It uses a long stroke gas piston and a two-lug rotating bolt to operate Compared to other contemporary rifles it was a quite light and sleek design although it was a bit awkward to handle It also had a couple neat extra features including a magazine cartridge counter and a selector to allow either semiauto or manual operation
2016/12/4It has an interesting piston motion tdc is at 19 4 atdc and bdc is at 208 6 so tdc of the big end and piston are different Ideas on how this would effect inertial torque behaviour I've written some ruby code to model piston motion using TDD with hand calculated numbers in the tests still not sure i have it correct thou
2017/8/2On top of the piston you put more metal (or polymer) then you add some sort of carrying handle where you put your optic On top of the optic you put another optic Yes I'm aware that all G36s don't come with optics like pictured below but even with a normal specification you have a sight line which is very high above the bore and you are forced to compensate a poor design with cheek welds
2007/10/21'Slope mill' the dome along the pin axis The outside of the dome exhaust side even with the piston crown The outside of the dome intake side at near maximum height Yes you'd obviously lose some geometric compression ratio Then take 2 -4 of total ignition
This article will unveil the origins of the humble Dolla air pistol We will discover the five variations of this air pistol its manufacturers and some interesting personal relationships between them with Friedrich Langenhan central above all others A story spanning two

A connecting rod for an internal combustion engine consists of the 'big end' 'rod' and 'small end' The small end attaches to the gudgeon pin (also called 'piston pin' or 'wrist pin') which can swivel in the piston Typically the big end connects to the crankpin using a plain bearing to reduce friction however some smaller engines may instead use a rolling-element bearing in order to

The company took two patents for the gun and both (DE 712 136 and DE 724 418) were signed on by Louis Stange The quality of manufacture is very high this is certainly not some workshop model but a machine-manufactured at least semi-serial produced weapon

I got a really interesting patent in my mail recently from Othais at CRsenal It's and idea clearly based on a Bergmann 1894 or 1896 pattern pistol but instead of being blowback it uses a gas piston Today I am visiting Simpson Ltd in Galesburg Illinois – a gun
The piston 1 is made from an aluminum-silicon alloy and has a diameter of 78 mm The gudgeon pin bosses 2 are integrally formed and extend from the piston head The distance T from the radially outer surface of the gudgeon pin boss 2 to the piston axis is 23 mm
2013/1/30With all these pistons around I thought I would weigh them to see how much they varied across bore size and between vendors I used an old triple beam balance that I calibrated against the weight of 10 pennies I measured each piston with rings wrist pin and
A positive displacement pump especially designed for home use comprises a crankcase housing and a cylinder block joined thereto the cylinder block containing a cylindrical bore whose longitudinal axis is at a predetermined angle relative to the longitudinal axis of the pump's drive shaft journaled in the crankcase housing A piston having a central longitudinal bore formed inward from one end
Michael Boyd has filed for patents to protect the following inventions This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO)
A piston is within the central bore of the housing The piston includes a piston shoulder that creates an upper recess within a central bore of the piston A ring having a locking profile is selectively connected to the second end of the piston between the housing and the piston and a spring is positioned around an exterior of the piston
The pin aligns the feed tube assembly into the backhead Page 7 PISTON The piston functions as the only moving part in the hammer control ling the operational air cycle The percussive action of the piston striking the bit transfers the energy through the bit in order to fracture rock formations

The HAC appears to have both a joint allowing the piston some play – and a shorter and therefore (assuming equal cross section) stiffer piston rod than an AK The HAC's gas system is going to complicate dis assembly compared to an AK but with 7 62*51 the chances of meeting corrosive priming was extremely small and I think that the compromise is a good one

A duct from near the top of the skirt of a two-piece piston carries lubricant to the skirt pin bore on each side of the skirt and lubricates the pin joint The skirt is provided with a lubricant passage such as from a shaker tray to the pin bore on each side of the pin
2 The piston from claim 1 wherein the outer section widening in the direction of the piston outer area has each pair of diametrically opposed points in each plane perpendicular to the piston-pin bore axis along the outer section asymmetrically disposed with respect to the piston-pin axis so that one point of each pair of diametrically opposed points in each plane is disposed closer to the
A piston-pin lock-ring-insertion tool has a ring-insertion tube (1) in ring-insertion relationship to a ring pusher (2) The ring-insertion tube has an inside periphery with a press-close taper (8) that is tapered inwardly from a ring-feeder end (6) to a ring-guide bore (9) that is cylindrical uniformly intermediate the press-close taper and a ring-insertion end of the ring-insertion tube

Five-stroke engine is currently a concept engine invented by Gerhard Schmitz in 2000 Schmitz's concept is being developed by Ilmor Engineering Ilmor's prototype is an internal combustion engine uses a solid cylinder block with electric motors driving the oil and water cooling pumps
2015/8/21With 20 bars pressure under the step piston acting on the say 50cm2 back surface of the piston (note: with 54mm bore the piston crown surface is only 23cm2) the restoring force is only 1ton (i e 4 times less than the required inertia force at 30 000rpm)
