Abstract: 617,146. Making nuts. ELASTIC STOP NUT CORPORATION OF AMERICA. March 24, 1944, No. 5490. Convention date, March 8, 1943. [Class 83 (ii)] [Also in Group XXV] Pronged sheet metal containing-members for anchoring nuts to plywood &c. are blanked out to the shape shown in Fig. 2, scoring being at the same time effected along the dotted lines if desired to facilitate bending. The central part 24 is next divided transversely and as a further step lugs 46, Fig. 6, are bent upwards and lugs 44 downwards. Parts 28, Fig. 9, are bent upwards and the prongs 26 and lugs 42 downwards. The central opening in the blank is elongated at 20, Fig. 2, enabling the lugs 42 to bend from the body with an appreciable radius. In assembly a nut is placed in the member with opposed edges between the lugs 46 and the bottom of the corners resting on the bottom of the notches 30. The nut is then turned relatively to the member so that corners of the nut seat in the notches 32, Fig. 2, causing the parts 28 to splay outwards and grip the nut frictionally. The parts are now in position for handling as a unit and for assembly in a structure. The Specification in the original form as open to inspection under Sect. 91 describes the manufacture of a modification in which the lugs and prongs may be embedded in the plywood &c. simultaneously instead of in two operations. The prongs 26a, Fig. 20 (Cancelled), are made sharper and the blanking dies are formed to produce ribs or embossing at 16a to strengthen the blank. The remainder of the manufacture is carried out as before. This subject-matter does not appear in the Specification as accepted.

Title: Toy vehicles
IPC: A63H29/04
Filed: 1972-02-07
Abstract: 1338338 Spring motors TONKA CORP 7 Feb 1972 [8 Feb 1971] 5595/72 Heading F2S [Also in Division A6] A toy vehicle has a spring motor driving through a first gear train to the road wheels and a second gear train between the road wheels and the motor to transmit drive from the road wheels when the vehicle is pushed in one direction to wind the motor, operation of the first gear train occurring when the second gear train is disconnected, the first gear train including a unidirectional slip clutch which disconnects the gear train when the vehicle is pushed in the opposite direction to the direction already referred to. As shown, a toy car has its front axle 5 slidable in vertical slots 7 in brackets 6, and its rear axle 10 slidable in slots 9 in a main frame 8 fast with the car body. A secondary frame 11 pivots about a pin 12 across the main frame 8, rests at its rear on the top of the rear axle 10, and carries a spring 14 at its front biasing the parts to the position shown in Fig. 1. By pushing the car down in the direction of the arrow P, the secondary frame 11 is turned to the position shown in Fig. 2. A spiral spring 17 of a clockwork motor, fast at one end with the main frame 8, is secured at the other to a winding shaft 18 journalled in the main frame and fast with a gear 19, meshing the smaller gear 25 of a gear pair 25, 26 fast on a lay-shaft 24 slidable along arcuate slots 23 in the main frame. With the motor spring 17 wound, the gear 19 slides the lay-shaft 24 along the slots 23 to mesh its gear 26 with the smaller gear 15 of a gear pair 15, 16 fast on the rear axle 10, and thus drive the rear wheels, as shown in Fig. 1. When the motor spring 17 has unwound, the lay-shaft 24 slides forward along its slots 23, bringing the gear 26 out of mesh with the gear 15, so that the car can be freely pushed back- and-forth. To wind the motor spring 17, the car is pushed down to the Fig. 2 position; a gear 20, journalled upon the winding shaft 18, then meshes with the larger gear 16 fast on the rear axle 10. If the car is now pushed forwards, drive is transmitted through the gears 16, 20 to a one-way clutch 21, 22 and the winding shaft 18, so that the spring 17 is wound; if, however, the car is pushed backwards, the oneway clutch 21, 22 over-runs. Unwinding of the spring 17 is restrained by the gear 26 engaging the gear 15 again. When the downwards force on the car is removed, the spring 14 restores the Fig. 1 position.

Title: Improvements in or relating to fluid pressure control mechanism
IPC: B64D13/04
Filed: 1956-02-24
Abstract: 817,216. Fluid-pressure servomotor-control systems; valves. GARRETT CORPORATION. Feb. 24, 1956 [March 1, 1955], No. 5776/56. Class 135. An aircraft cabin or other enclosure 10, which is pressurised by a blower 11, has an outlet 15 controlled by a butterfly valve 17 on a shaft 18 to regulate the enclosure pressure; with the aircraft on the ground an electric actuator 76 is automatically energized to rotate a cam 75 and hence an arm 74 on a quadrant 24 clutched to the shaft 18 so opening the valve and maintaining the enclosure at ambient pressure. Limit switches 77, 78 actuated by the shaft 18 de-energize the actuator when the valve is in either extreme position. A control chamber 50 in the enclosure has a bleed outlet 52 to the enclosure and an outlet 53 to atmosphere; prior to take-off the pressure in the chamber 50 is atmospheric, which pressure is transmitted to a chamber 47 divided by a diaphragm 46 from a chamber 48 open to the enclosure through a filter 61, the diaphragm 46 being thereby elevated and lifting a valve closure 69 against a port 66 in a seat member 63. The latter is open to both chamber 48 via the port 66, and to the outlet 15 or a vacuum source, not shown, by way of a port 65, whilst a space 36 above a power diaphragm 34 is also connected to the seat member 63 by a pipe 73; the underside of the power diaphragm 36 is subjected to enclosure pressure via openings 42. Closure of port 66 places space 36 in communication with atmosphere through port 65 so that the pressure differential across the diaphragm 34 holds the valve 17 open since a plate 33 forming the diaphragm centre is connected to a peripheral groove on the quadrant 24 by a cable 38. At take-off the actuator 76 disengages the arm 74 and as the aircraft climbs a drop in atmospheric pressure occurs, and should the pressure in chamber 48 fall below that in chamber 47, which reduces at a given rate, the resultant upward force on diaphragm 46 causes downward. movement of closure 69 and partial opening and closing of ports 66, 67, respectively, thereby raising the pressure in space 36 and downwardly moving diaphragm 34 so enabling a spring 26 to partly close valve 17 and maintain the enclosure pressure at the level obtaining in chamber 47; the reverse process occurs when the aircraft dives. The control pressure in chamber 50 may be varied to change the pressure differential across diaphragm 46. Upon pulling a cable 80 the arm 74 lifts the quadrant 24 to break the clutch connection between the latter and shaft 18, whereupon spring 26 closes valve 17 which cannot be automatically actuated again until the clutch connection is re-made. Specification 695,065 is referred to.
