Title: A hydropneumatic shock absorbing device
IPC: F16F9/06
Filed: 1963-02-15
Abstract: 1,038,662. Hydro-pneumatic railway vehicle draw-gear. Z. O. KARAKASHJAN, A. I. TIMOSHUK, and F. S. MARKANOV. Feb. 15, 1963, No. 6300/63. Heading B7T. [Also in Division F2] Railway vehicle hydro-pneumatic draw gear comprises a cylinder 4 movable within a casing 1, a metering piston 3 fixed to the cylinder 4 and movable in an oil-filled chamber B, a pistonrod 7 slidably mounting the piston 3 and slidable itself within a fixed partition 8, a piston 5 floating in a low compression gas chamber A, a piston 6 floating in a high compression gas chamber C, and a safety valve 23 operative on sudden heavy impact. In operation, as the cylinders 1 and 4 telescope, oil flows from chamber B through holes 11, 12 and 14 in the piston 3 into chamber B 2  to move the floating piston 5, and into chamber B 1  to create an hydraulic seal in grooves 19. The cylinder 4 and piston 3 then move further and abut the shoulder on the rod 7 and move the piston 6 into the chamber C against the high pressure of gas therein. The shoulder on the rod covers the slots 12, see also Fig. 2 (not shown), and increases the hydraulic resistance. The compressed gases in the chambers A and C effect recoil, and the fluid flows back from chambers B 1  and B 2  into chamber B. As the fluid returns it presses a loose ring 15, Fig. 3, against the flange 13 on the piston 3, and as the slots 12 are closed off by the shoulder on the rod 7 for part of the recoil action, then the recoil takes place against resistance and is consequently smooth. A piston 28 having an extreme outward position limited by a bolt 29 acts against oil in chamber D to provide an hydraulic seal in grooves 31.

Title: Improvement in circular knitting machines
IPC: D04B1/28
Filed: 1920-03-02
Abstract: 152,981. Hemphill Co., (Assignees of Bosworth, G. P.). Oct. 22, 1919, [Convention date]. Circular machines. -Broad selvedged webs having joined therewith a group of narrow strips, e.g. glove blanks are knitted on circular latch-needle machines with rotary needle cylinders by means of mechanism which comprises knitting-cams, needles with selective butts grouped for strip-production, means for retiring needles prior to selection for each strip, groupselective cams for selecting the needle-groups required in knitting successive narrow strips, needle-restoring means, and cam controlling devices. Prior to selection of a group of needles for knitting a narrow strip, a withdrawal cam 2 is pressed in towards the needle-cylinder N by a spring. Normally the cam 2 is held out by means of link-work under control of the pattern gear. The knitting-butts 1<a> are thus engaged and the whole of the needles are elevated out of the way of the knitting-cams, and the lower selective butts 3<a> - - 7<a> are brought up to the level of the groupselective cams 3 - - 7 as shown in Fig. 3. By pressing in one of the cams 3 - - 7 when such movement is permitted by the pattern control drum g the corresponding group of needles can be brought down for knitting a thumb or finger strip. The groups of butts 3<a> - - 7<a> overlap, as shown, to provide for the formation of gussets between the finger strips. Thus some of the needles with butts 4<a> which are brought down by the cam 4 to knit the little-finger strip have additional butts 5<a> and are brought down again when the cam 5 is put in to bring down the needles with butts 5<a> for knitting the third-finger strip. After all the finger strips are knitted the needles are all restored to the operative level by a cam 8 and a broad selvedged web for the back of the hand and wrist is begun. The hand and v.rist portion may also be made by round-and-round knitting. The bell-cranks 2<r>, 8<r> for the cams 2, 8 are connected by links 2
, 8
 to the same pattern lever 2<t> so that when one is held out of section the other is pushed in and vice versa. The cams 3 - - 7 are operated by means of a range of pattern-levers g<1> under control of the drum g and connected by links g<3> to bell-cranks 3<r> - - 7<r> carrying cam-bars such as 3<t>. Each of the cam-bars have inclined surfaces such as 3<v>, which co-operate with notches such as 3<u>, Fig. 15. in sliding stems such as 3<m> of the corresponding cams 3 - - 7. When the cam-bars occupy the position shown in Fig. 8, the flat surfaces such as 3<x>, Fig. 14, keep the respective cams 3 - - 7 in the outward inoperative positions. When a cam-bar is moved to the left, the incline 3<v> permits a spring to move the stem 3m carrying the cam 3 radially inwards towards the needle cylinder.
