Title: Improvements in or relating to mudguards for wheels of perambulators, toy motor cars, and other juvenile road vehicles
IPC: B62J15/00
Filed: 1931-12-12
Abstract: 385,731. Mudguards for perambulators &c. WASDELL, T. E. and CHATWIN, G. F., Holdford Road, Witton, Birmingham. Dec. 12, 1931, No. 34475. [Class 136 (i).] In mudguards for the wheels of perambulators, toy motor cars, and other juvenile vehicles, and of the type in which the mudguard stays a<2> are connected to the axle d by means of a centre bracket c, a clamping-strap e, and one or more bolts f, the bracket c is slotted at c<3> to receive, in a detachable manner, the T-shaped head f<2> of the bolt f, which is inserted laterally, and then allowed to drop so that its head f<2> engages the inner wall of the bottom of the bracket c to prevent rotation when the nut f<4> is applied. The bottom of the bracket c may be of bulbous form as shown. The strap e may be pivoted at e<2>, or two detachable bolts f with their corresponding slots c<3> may be provided, one on each side of the axle d.
Patent GB-523154-A (GB)
Title: Improvements relating to the tuning of radio receivers
IPC: H03J5/22
Filed: 1938-11-26
Abstract: 523,154. Push-button tuning. COLE, Ltd., E. K., and KENNEDY, F. W. O. Nov. 26, 1938, No. 34506. [Class 37] In a motor operated push button tuning mechanism comprising a plurality of actuating bars each individual to a press button, depression of a push button effects in turn (1) the selection of the appropriate actuating bar, (2) the energization of a motor, (3) the movement by the motor of the actuating bar to effect the required tuning operation, (4) the return of the motor mechanism to its original position and (5) the release of the actuating bar. The actuating bars 2 are of known type each carrying a cam 5 which coacts with a transverse rocker bar 6 operating the tuning impedances. Each bar carries a pivoted catch 13 normally held in a raised position by a projection 15 on the rear bracket 4 of the apparatus. On depression of a push button 1 the bar 2 is moved to the left thus freeing the catch 13 and at the same time closing the switch 18 which energizes the motor 7. This latter is coupled through gearing 8 to a shaft 10 pivoted to a reciprocating member 11 supporting side bars 12 and transverse bar 12a. On energizing the motor the bar 12a is thus reciprocated so as to engage the detent in the catch 13 and thus move the bar 2 and the associated tuning impedances to the required tuning position. After the bar 12a is arrested the plate 11 continues to move forward for about inch against the force of a spring 17, the further movement ensuring that the cam 5 is properly engaged with the rocker 6. Further movement of the motor retracts the bar 12a which is finally set free by the upper part 14 of the catch 13 riding over the member 15 while the motor is brought to rest by a cam on the shaft 9 opening the switch contact 18. The modification shown in Fig. 2 provides also for manual and "cruising" operation. The manual tuning knob 33 is connected to the variable condensers by a cord 28 wound round the condenser spindle 29 and terminating in lever arms 31, 30, the latter being fixed to the rocker bar 6. The opposite arms of the levers are tensioned by a similar cord incorporating a spring. The motor 8 is coupled to the shaft 34 through a clutch 35 adapted to engage one of two discs 36 driven from the motor gearing and brought into alternate operation according to the position of a control handle 37 thus reversing the "cruising" tuning direction at will. The actuating bar 25 is provided with a pin 26 which engages in a slot in the gear wheel 8. Specification 445,350, [Group XL], is referred to.

Abstract: 1363886 Flexible hose DUNLOP HOLDINGS Ltd 16 June 1971 [18 June 1970] 34925/71 Divided out of 1320508 Heading F2P A flexible hose is formed by winding a reinforcing tape, composed of a plurality of wires laid side-by-side and secured together by a coating of elastomeric material, on to a lining layer, applying an outer cover, and vulcanizing the assembly, the reinforcement so formed being either a plurality of spaced convolute coils, or a helix with spaced convolutions. As shown, a hose comprises a first layer of uncured rubber wrapped on a mandrel, a breaker layer 2 of rubberized fabric, an uncured rubber layer 3, a further rubberized breaker fabric layer 4, a filler 5 of uncured rubber, and several plies 6 of fabric reinforcement coated with uncured rubber. Reinforcing rings 7 of the elastomerbonded wires are then formed and the spaces between the rings filled with natural or synthetic rubber, the outer lining of the hose comprising fabric breaker layer 9, cord or fabric holding ply 10, sub cover 11 of uncured rubber and outer coat 13 of rubber. The hose is tightly wrapped with nylon tape and vulcanized, the tape being subsequently removed. In an alternative method the rubber filler 8 may be formed first and the reinforcing tape wound into the channels so formed. In a second embodiment (not shown) the reinforcing tapes 7 are wound so as to form a multiply helical band having open convolutions of substantially rectangular cross-section. Such tapes may be wound in a helical channel formed between a rubber helix formed on the inner lining or may be wound first so as to leave a helical space which may subsequently be filled with polymeric material (e.g. by closed cell foam in the case of a buoyant hose). The reinforcing fabric plies 6 may be replaced by a conventional wire cord reinforcement. The wire used to form the reinforcement tape may be solid drawn or stranded and may be die drawn as disclosed in the parent Specification 1,320,508. The elastomer binder is conveniently formed by passing the wires through an extruder. End fittings may be applied when required.

Drawings to Specification. [Class 41] [Also in Group XXVII] In a sparking-plug the sparking tip of one or both of the electrodes is formed of a core of copper, silver or an alloy of these metals, encased in a nickel sheath, which latter is coated with an electrodeposition of platinum, palladium or an alloy of these metals (see Group XXVII). Platinum may be electrodeposited from complex sodium platinate baths or from phosphate sulphate or nitrite ammine baths. It is stated that a fairly heavy plate of palladium may be produced from the following bath composition and condition. Palladium as PdCl2-50 grammes per litre, ammonium chloride-20-50 grammes per litre, temperature-50‹ C., current density-10 amps per square foot, agitation-air lift. When plating upon nickel, a preliminary strike from a low metal ion concentration bath of palladium or one of the other noble metals is preferably deposited first. The alloys of platinum or palladium which may be used to form the electrodeposited coating are platimun - palladium, platinum rhodium or chromium, palladimn and rhodium or chromium. The alloying is done by co-deposition or by plating the elements on to each other and forming the alloys by a diffusion process such as heating the plated assembly in a non-oxidizing atmosphere.
