Title: Hydraulic drives
Inventor: STUART DUNCAN JAMES KEITH
IPC: B23Q5/26
Filed: 1964-07-25
Abstract: 1,110,872. Lathes. EDWARD WILLIAMS HOLDINGS Ltd. 5 July, 1965 [25 July, 1964], No. 26279/64. Heading B3T. [Also in Division F1] The turret slide of an automatic lathe is moved by a member 18 connecting the piston rods 16, 17 of a pair of double-acting hydraulic cylinder units 14, 15 provided with conduits 37a, 38a for the supply and exhaust of liquid thereto and having valves 39, 43 pneumatically operated under the control of a programming system to change the speed of movement of the member 18 by changing the connections between the conduits 37a, 38a and the cylinder units 14, 15. Liquid is supplied to the conduit 37a or the conduit 38a through a reversing valve 34 having a port 35 connected to a line 32 pressurized by a pump 65 and also, if desired, by a further pump 61. The rate at which liquid is exhausted by the units 14, 15 is controlled by a speed control device 33 which operates to maintain a constant rate of flow therethrough in accordance with its selected setting. If the conduit 38a is pressurized, the right hand sides of the cylinder units are pressurized and the member 18 moves to the left at a speed dependent on the rate of exhaust from the left hand sides maintained by the speed control device 33. If now the valves 39, 43 are changed over, both sides of cylinder unit 14 are pressurized and both sides of cylinder unit 15 are connected to exhaust. Since the unit 14 has a dummy piston rod 27 of larger diameter then its rod 16 the member 18 continues to move to the left and its speed is increased since the flow through the device 33 is maintained constant although liquid is now only exhausted from the left hand side of the unit 15 and part of this exhaust passes to the other side thereof. The lathe cross slide is moved by a member connecting the piston rods 23, 24 of a second pair of units 21, 22 operated by the pump 61 and controlled by valves 50, 57 and a speed control device 56 in a similar manner to that described above.

Patent GB-1292738-A (GB)
Title: Variable index finger assembly for controlling articles on conveyors
IPC: B65G47/29
Filed: 1970-06-02
Abstract: 1292738 Temporarily stopping articles on endless conveyers AMF Inc 2 June 1970 [2 June 1969] 26479/70 Heading B8A Articles (not shown) to be packaged by a machine 20 are fed in succession by conveyers 12, 14 and 18, and are controlled on the conveyer 14 by an assemblage of index fingers 42. The assemblage is movable between a position (full-lines) in which it blocks the movement of conveyed articles, and a retracted position (dotted lines) and is movable in a direction parallel to the direction of conveyance. The fingers 42 are mounted on transversely extending rods 134, 136 (Fig. 4). These are mounted on a pair of carriages 130, 132 (132 only, visible in Fig. 4). The latter are slidably mounted on respective rods 118, 124 by the action of links 170, 172 connected to respective threaded members 182, 194. By rotating manually a handle (272, Fig. 2, not shown) on a rod 216 connected by bevel gearing to threaded rods 184, 196, the threaded members 182, 194, are longitudinally displaced. This results in longitudinal displacement of the fingers 42. Rotation of a cam 142 acts on a follower 152 and via linkage 158 and crank arms 160, 162, and 164, to raise and lower members 43 and 44 (44 only, visible in Fig. 4). The rods 118, 124 on which the fingers are mounted are themselves mounted on the members 43 and 44. Thus by rotating the handle (222), the fingers 42 may be raised and lowered relative to the conveying surface. The conveyer consists of laterally spaced resilient endless load-carrying members 26 each mounted between longitudinally-spaced rollers 28. There may be a second series of fingers 42 which may be raised and lowered but have no longitudinal movement.

Title: A process of producing dis- or polyazo-dyestuffs
IPC: C09B33/00
Filed: 1933-09-26
Abstract: Insoluble dis- or polyazodyestuffs are prepared by coupling diazo compounds and such coupling components as have two or more positions capable of coupling under the same conditions in the presence of an organic base of the pyridine series.  The diazo compounds and the coupling components are free from groups which would impart solubility to the finished dyestuff.  The dyes may be prepared on a substratum or on a fibre of vegetable origin such as cotton or regenerated cellulose or of animal origin such as silk or wool.  In examples (1) cotton impregnated with a solution of di(p-cresotinic acid)-benzidide containing caustic soda, sodium chloride and turkey red oil is treated with a neutralised solution of diazotized 4-chloro-2-aminodiphenylether containing pyridine to yield a brown tint; (2) cotton impregnated with an alkaline liquor containing di-(2 : 3-oxynaphthoyl)-dianisidide is treated with a solution of diazotized o-aminoazotoluene to yield a bordeaux tint.

Title: Improvements in and relating to ejection seats for aircraft
IPC: B64D25/10
Filed: 1956-08-31
Abstract: 814,412. Aircraft ejection seat mechanism. MARTIN, J., and MARTIN-BAKER AIRCRAFT CO. Ltd. May 1, 1957 [Aug. 31, 1956], No. 26665/56. Class 4. [Also in Group XXV] An aircraft ejection seat comprises mechanism for delaying drawing out of a main parachute after drawing out of a drogue parachute, and inertia operated means for preventing drawing out of the main parachute so long as the seat is subject to retardation in excess of a predetermined value. In the embodiment described ejection of the seat is followed by deployment of a pilot drogue parachute and a main drogue parachute, the latter being attached to the top of the seat. On actuation of the mechanism shown in Figs. 2 and 2b which is mounted on the seat the main drogue is released from the seat and deploys a main parachute attached to the user, who is released from the seat, which falls away. These releases are effected by a rod 10 driven by a spring 14 acting between the housing shown and a plunger 13 abutting a head 12 on rod 10. The plunger is normally restrained by a sear 16 on a shaft 17 which is freed to rotate by withdrawal of a pin on a static line after ejection. Part of rod 10 is toothed and engages a gear train (parts 19, 20 shown) terminating in an escapement wheel 27 and rocker 28. While the seat is subjected to a retardation above a predetermined value, a mass 32 pivoted on a shaft 33 compresses a spring 37 and engages a pawl 34 with the escapement wheel 27, and while the seat is above a predetermined height, a barometric capsule 41 engages a detent, Fig. 2d (not shown) with the escapement wheel. Thus fater ejection rod 10 is free to rotate the gear train when the seat is or has fallen below the predetermined height and has ceased to decelerate too quickly. Rod 10 then moves slowly until the toothed part disengages from the gear train, when it is free from all restraint, and is moved by spring 14 to release the main drogue parachute and the user from the seat and deploy the main parachute. Specifications 583,257, 640,520. 652,131, 673,147 and 711,234 are referred to.

Abstract: 811,208. Photographic cameras. DECKEL, H., and DECKEL, F. W. Aug. 29, 1957 [Sept. 28, 1956], No. 27246/57. Class 98(1) As shown in Fig. 1, a photographic camera with a shutter-speed setting ring 5 movable over a primary range for automatically timed exposures or to a "bulb" exposure position, and preferably having an aperture-setting ring .6 which may be coupled to the ring 5 by means of a releasable coupling element 10, is characterized in that the ring 5 is movable beyond the primary range into a second range and means for setting the shutter to its "bulb" position operate over the whole of the second range, a secondary scale of exposure times longer than those obtainable by automatic timing being provided on ring 5. The scale 7 on ring 5 includes primary scale of automatically timed exposures 1 sec.-1/500 sec., and a secondary scale 2 sec.-250 sec. which is differentiated in colour or by associated markings from the primary scale. Ring 6 bears a diaphragm aperture scale 8 which, together with scale 7, is read against a fixed mark 9. The rings 5, 6 are adjusted relatively to each other in accordance with the light value by means of a scale 11 on ring 5 read against a mark on coupling 10, which ensures that the rings may thereafter be moved together until a suitable diaphragm aperture is indicated on scale 8. If the corresponding exposure is indicated on the primary scale, the exposure is made by releasing the shutter in the usual way. If it is indicated on the secondary scale, the release is held down for the period indicated. The shutter speed setting cam connected to ring 5 is arcuate where it engages the "bulb" controls over a sufficient range to ensure that the shutter is set for "bulb" exposures over the whole secondary range of scale 7. Springs or releasable catches may be provided to indicate to the operator the change-over from the primary to the secondary range. Specification 769,081 is referred to.
