Filed: 1963-04-01
Abstract: 1,082,944. Beds. EDWARD DOHERTY & SONS Ltd. June 17, 1964 [April 1, 1963], No. 12797/63. Heading A4H. A couch or bed is provided with a step 16 which is pivotally attached to the couch in such a manner that it can be moved to at least three positions such that it is either at one side or the other of, or lies beneath, the couch. Step 16, Fig. 1, is connected by means of a telescopic arm 18 to a slide 20 which slides along a strut 22 of the couch. Slide 20 is also rotatable about strut 22 and outer tube (26) is rotatable about inner tube (24) of the telescopic arm, Fig. 3 (not shown). In a modification, Fig. 4, step 16 is connected to an arm 36 which swings in a horizontal plane about a pivot 44 on slide 20. A further pivot 40 enables step 16 to be swung over strut 22. Pivots 40, 44 may be replaced by a ball joint. In a further modification, Fig. 5 (not shown) the step is attached to slide (20) by a pair of arms having pivotal elbow joints so that the step can be moved towards and away from strut (22). The step has no legs and has a tread on its upper and lower surfaces so that it can be used on either side of the bed simply by swinging it over strut (22).

Title: Improvements in or relating to shoe upper conforming machines
IPC: A43D13/00
Filed: 1942-09-11
Abstract: 560,038. Lasting machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Sept. 11, 1942, No. 12814. [Class 17 (i)] Relates to machines of the kind described in Specifications 475,127 and 507,490 and consists in an improved ,work support. The toe rest and heel end support are independently spring supported. The preliminary clamping of the work piece has the effect of swinging the last about the toe rest and stretching the upper lengthwise of the last. The heel and toe supports are connected so that depression of the toe rest causes corresponding depression of the heel end support. During this depression the gripper gives the heightwise pull to the upper. A heel end rest moves and tips laterally with the last pin spindle, and is brought into abut. ting relation after the work has been positioned. The toe rest 8 is mounted on a hollow plunger 10 movable downwardly in a holder 12 against the resistance of a spiring 14. A rod 18 transmits this movement to a shaft 160 con.nected by arms 158 to horizontal shaft 156 mounted in bearings in the frame. The shaft 160 carries a roll- 164 co-operating with lug 166 on the heel'end support to impart thereto the same downward movement as that of the toe rest. The heel support is adjustable longitudinally of the work by a hand-wheel 50 and vertically by a handle 60. It is slidable laterally to suit right or left shoes to limits determined by adjustable stops. The last pin 34 is capable of lateral swing about a pivot 80 against centralizing springs. The: pin is secured to a block 82 carrying a lever 104 pivoted at 106 and suppdrting the heel end abutment comprising a leather band 98 backed by a resilient metal plate 122 .supported by pairs of arms 126, 128 pivoted at 130, 134 to a block 132 adjustable longitudinally of the last by a screw 136 and vertically by a screw 150. Instead of providing that the gripper 2 should be movable by the operator lengthwise of the last to tighten the upper lengthwise of the last, the parts are so arranged that the swing of the work about the toe rest under positioning pressure of the members 28 described in the prior Specifications, from the point where the last pin just enters the hole in the last, is sufficient to give the required lengthwise pull to the upper. Such swing depresses the inner end of the lever 104 to swing the heel end abutment up to the shoe. Before contacting with the shoe the abutment is shifted laterally and angularly with the last pin.

Title: Improvements in door locks
IPC: E05B65/32
Filed: 1935-04-30
Abstract: 455,970. Door fastenings. HULBERT, J. C., 37, Wildwood Road, Golders Green, London. April 30, 1935, No. 12876. [Class 44] In a lock for the doors of motor cars &c., where the door frame is subjected to vibration or distortion, a swinging latch 1 pivoted at 2 and loaded by a spring 28 is adapted to engage an inclined slot 6, Fig. 7, in the striking plate 7 so that under vibration the latch tends to move down the slot and tighten the door, and when unlocked by the handle, the latch forces the door slightly open. Fig. 1 shows the position with the door open in which the latch 1 is held inoperative by the engagement of a tooth 17 with a tooth 21 on a pivoted spring-urged plate 18. When the door is closed the nose 4 of the latch first engages a slanting surface 54, Fig. 3, on the striking plate 7. This releases the engagement 17, 21, and then the end 23 of a plunger 22 contacts with the striking plate and rocks the plate 18 to take the tooth 21 out of the path of the tooth 17. The spring 28, acting through a lever 25 pivoted on the plate 18 then rocks the nose 4 down the slant edges 8 of the slot 6. To open the door the latch is rocked upwardly against the slant edge 9, thus easing it, by an outside handle 10, 11 acting through levers 13, 15, or by an inside handle 55 acting through a sliding plate 47. An extreme movement of the inside handle in one direction prevents the door from being opened from the outside. This may be rendered inoperative. A detent 39 is arranged to prevent the latch from jumping out of the striker slot when the door is closed. The spring 28 loads all parts of the lock to avoid rattling.

Title: System for controlling the performance of electrically operated apparatus by means of a measuring device
IPC: G05B1/04
Filed: 1927-05-13
Abstract: 271,105. Siemens & Halske Akt.-Ges. May 14, 1926, [Convention date]. Tell-tale apparatus. - An electric contactmaking device closes different circuits according to different positions of an instrument pointer for the purpose of controlling a motor or other electromagnetic mechanism which may set water-level indicators or actuate ships' rudders, or regulate steam-boiler furnaces, or execute any other definite action required to conform to the instrument reading. The closure of the electric circuit is effected by force which is independent of the instrument, and is applied so as not to interfere with the freedom of movement of the pointer. In one form of the device shown in Figs. 1 and 2, the pointer 1 carries a plate 3 below and clear of a pair of rockers 8<a>, 8b, which receive downward movement from electromagnets 15 excited automatically or otherwise. According to the horizontal position of the pointer, one or the other of the rockers is free to pass down between fixed bars 4, 5, and in so doing to close one of two pairs of electric contacts switching on a motor 30 for opposite directions of running. The motor then executes the required indicating or regulating action. In a modification the electric contacts are carried on an upper rocker which bears on one of the lower rockers when the pointer obstructs downward movement.

Abstract: 1,140,574. Making plates and sheets; working at specified temperature. ARMCO STEEL CORP. 25 March, 1966 [2 April, 1965], No. 13317/66. Headings B3A and B3V. [Also in Division C7] Silicon steel having a cube-on-edge structure is produced from stock containing 2% to 3À5% of silicon and 0À03% to 0À15% of manganese by hot-rolling, cold-rolling to a final thickness of 7 mils. or less with or without intermediate anneals, decarburizing, and annealing to effect recrystallization. During the primary grain growth stage of the anneal there is provided in the environment of the steel a grain-growth inhibitor consisting of sulphur or selenium, possibly in the form of one of their compounds, so that the inhibitor diffuses into the grain boundaries and encourages the development of the desired grain orientation during the secondary stage of annealing. The amount of inhibitor in the environment is adjusted to the manganese content and the thickness of the strip in accordance with guidance given in the Specification. The inhibitor may, if gaseous, such as H 2 S, S0 2  or SF 6 , be added to the annealing atmosphere, or if solid, such as elemental sulphur, copper sulphide or iron sulphide, be added to the annealing separator, which may be calcium oxide, magnesia, alumina, titanium oxide or other refractory oxide; in an alternative embodiment the inhibitor may be added to the atmosphere during the decarburizing step whereby a coating of sulphide is formed on the surface of the steel so that on subsequent annealing the inhibitor element diffuses into the grain boundaries. As particularly described, the steel is hot-rolled from an initial temperature of 2550 F., annealed at 1675 F., cold-rolled, if necessary with intermediate anneals at 1400 to 1800 F., preferably 1675 F., decarburized in wet hydrogen at 1500 F., and box annealed at 1800 to 2300 F., preferably 2150 F. When cold-rolling is to be effected in a single stage the reduction should be 70%-85%, but when multi-stage rolling is employed the final stage should impose 60%- 80% reduction. Hot-rolling may be carried out from 2550 F.

Abstract: 1428111 Safety belt retractor IRVIN GREAT BRITAIN LTD 21 March 1973 [23 March 1972] 13677/72 Heading A3V [Also in Division B8] A retractor, e.g. for a vehicle safety strap 7, comprises a reel 1 biassed by a spring 6 in the winding direction, ratchet wheels 4 on the reel, pawls 5 for looking engagement with the ratchet wheels and means 8 for displacing the reel relative to the pawls into a position in which the pawls and ratchets are disengaged; the displacing means may become or be made inoperative in use Whereupon tension in the strap serves to produce locking engagement of the pawls and ratchets. In the embodiment shown the ends of the reel axle are displaceable in slots 2 in a bracket 3 and guides 8 on a bar 9 engage the periphery of the wound strap 7 to displace the reel. After the strap has been unwound to some extent the guides 8 become inoperative but stops 10 frictionally coupled to the reel hold the latter in disengaged position. Slight belt retraction disengages the stops and normal strap tension, substantially equal to the force of spring 6, suffices to displace the reel to locking position. In an alternative embodiment the reel locks under predetermined strap tension or vehicle acceleration. The reel is displaced to the disengaged position by a spring which is overcome by the predetermined strap tension. Means may also be provided for overcoming the spring bias in the event of the predetermined acceleration or vehicle-sensitive further pawl means may lock the ratchet wheels 4 or further ratchets on the reel. The reel may be displaceable with a component of motion parallel to its axis.
