Title: Improvements in or relating to track laying wheels for vehicles
IPC: B60B15/22
Filed: 1939-11-25
Abstract: 539,106. Endless tracks for vehicles. SINGER, O., and DEW, C. J. Nov. 25, 1939, No. 30798. [Class 79 (i)] An endless track comprises an even number of equal elements, at least six, pivoted together and further so connected together mechanically that diametrically-opposed elements are constrained to keep parallel to each other, disregarding friction in the element pivots, whereby the element approaching the ground at any moment is caused to move with a diminishing angular velocity which becomes nil on reaching the ground. In the construction shown in Figs. 1 and 2 a vehicle wheel 1 is surrounded by a track comprising six links 2 pivoted together at 3, one pair of opposite pivots being connected together by lazy-tongs linkage 4 mounted on the wheel axle, this ensuring that opposite links remain parallel to each other as long as the top link remains in contact with the top of the wheel 1. If the friction in the pivots 3 is exceptionally great other pairs of opposite pivots may be connected together, e.g. by half or the whole of a pair of lazy-tongs 5. When the wheel 1 has double tyres as shown in Fig. 2 alternate links may have respectively a central rib 6 engaging between the tyres and side ribs 7 engaging outside the tyres. Metal discs 8 may be mounted on the wheel to protect the inner sides of the tyres from rubbing by the ribs 6, and similar discs may be provided on the outer sides of the tyres for use with the ribs 7. The wheel 1 may have gear teeth to engage racks formed on the links 2. Modifications are described in which (1) a pair of tandem wheels 13, Fig. 5, run on a track comprising eight links 14, one pair of opposite pivots being connected together by lazy-tongs 15, (2) the constraint on the six links 21 of a track, Fig. 9, is exercised by three radius links 24 connected to a common floating pivot 22, the wheel axle 25 being connected for traction to the links by springs or linkages, or the wheel may have teeth gearing with rack teeth on the links, (3) instead of opposite pivots being connected by lazy-tongs they may be connected by telescopic tubes pivoted on the wheel axle, (4) symmetrical intermediate points on opposite links may be connected together instead of the link pivots, (5) the wheels 30 of a vehicle 26, Fig. 11, run on the upper links of an eight-link track 27, the vehicle wheel axles being connected by rods 31 to the axles 29 of wheels 28 running inside the track. In this construction the vehicle wheels are driven in the opposite direction to the wheels 28 and the movement of the track on the ground, and (6) in a construction of track similar to that shown in Fig. 11, the whole vehicle is entirely enclosed by the track.

Title: Improvements in or relating to tuning mechanisms for radio receivers
IPC: H05K11/02
Filed: 1955-10-28
Abstract: 814,533. Automatic timing of radio receivers. TELEFUNKEN G.m.b.H. Oct. 28, 1955 [Oct. 28, 1954], No. 30846/55. Class 40 (5). [Also in Group XXXVII] In a radio receiver of the type in which the tuning mechanism is caused to traverse a waverange until a signal is tuned in, means are provided for automatically changing the waverange after one or more traversals have been completed. The invention is described as applied to a receiver having a tuning mechanism moved by a spring which when the end of the waverange is reached is automatically retensioned by means of a solenoid 1 which also returns the tuning mechanism to the beginning of its range. The solenoid is connected to an arm 3 pivoted at 5 and carrying an arm 10 provided with a pawl 13. When a control member 23 is withdrawn and the solenoid is operated, the pawl engages a ratchet 11 secured to a cog-wheel 12 which drives a pinion 15 connected to a crank arm 16. The outer end of this arm is coupled to the operating member 21 of the wave-change switch through a hairpin spring 18, 19. The operation of the solenoid normally advances the ratchet two teeth and this causes the pinion to rotate through 180 degrees and thus to change the wave-range on each operation. The control member 23 may, however, be set so that the ratchet is advanced only one tooth, the first operation rotating the pinion through 90 degrees and operating the wave-change switch while the second operation carries the left-hand end of arm 16 beyond the position adjacent to the member 21 and back to it again, the excess movement being accommodated by the resilience of the hairpin spring. The waveband switching thus occurs only after every second traversal of each wave range. The arrangement is such that manual operation of the tuning and wave range controls is possible. In addition member 23 may be set so that the pawl is always clear of the ratchet-wheel and the automatic wave-change does not occur.

Abstract: 612,101. Egg and cream beaters. MORGAN, E. M. Oct. 18, 1946, No. 31088. [Class 86] An egg and cream beater comprises a pair of dasher rods 17 and 18 provided with interfitting coils 21 and 22 which move into and out of coplanar relationship With one another during their orbital travel in the same direction. The upper ends of the rods describe a common circular path, being pivotally connected by pin - encircling eyes 19 and 20 to one end of a crank arm 15 the other end of which is secured to the pinion 14 which is meshed with the gear 8. Intermediate portions of the rods 17 and 18 have sliding fulcrum engagement in openings 25 and 26 in plates 23, 24 located at different distances below the axis 13 of the pinion 14. The plate 24 has a slot 27 in which the rod 17 is free to swing. The fulcrum member 23 being located at a point closer to the axis than the member 24 causes the coil 21 to describe a wider path than the coil 22.

Abstract: 1396398 Vacuum cleaners R J DE BREY 4 July 1972 31289/72 Heading A4F [Also in Division G1] A vacuum cleaner is provided with a particle sensing device wherein an audible sound is produced which is proportional to the number of particles passing therethrough. When a vacuum is applied to a tube 303, a flexible sounding diaphragm 317 which is secured around its periphery flexes inwardly as shown, so that particles entering a tube 301 strike the diaphragm 317 to produce a sound which may be amplified by an extension sleeve 318, as shown. the relative orientations of tubes 301, 303 and diaphragm 317 causes particles striking the diaphragm to rebound thereoff and the device, therefore, is self cleaning. Various modifications are described but in all cases the central area of the sounding diaphragm is in alignment with the axis of the inlet tube 301. Mechanical protection of the diaphragm may be effected by a screen, e.g of wire mesh, on one or both sides thereof.

In a device for adjusting the carbons for a carbon arc the carbons are arranged to be axially slidable on guides 1, 2, Fig. 1, disposed near their striking ends, and are held by means of clamps 5, 6 at the remote ends of the carbons, the clamps being movable along a guide member 9 parallel to the axes of the carbons, such that a guide and clamping device of at least one carbon are jointly adjustable so that axes of carbons of different diameters can be set substantially colinear. This adjustment is achieved by means of an eccentric shaft 13. Thus when guide 2 is attached to arm 30 which is pivoted at 31 and fixed to spring 33, a stud 32 bears on the shaft 13. The clamp 6 is held by arm 4, Fig. 3, which also bears on shaft 13 ; thus by rotating the shaft by crank 34 the positions of the members 1 and 6 may be adjusted simultaneously to achieve coaxiality. The support members of the other carbon may be similarly designed.
