Abstract: 1,087,206. Sound generator for toy vehicle. MATTEL Inc. Sept. 9, 1965 [April 16, 1965], No. 38514/65. Heading G5J. Rotation of road wheel 622 turns friction wheel 656, when they are in engagement, and causes irregularly ribbed impeller 653 to turn against an abrasion-resistant body 635, causing cone 632 to emit sound. With a suitable choice of material and dimensions for cone 632 a distribution of frequencies resembling that of a motor vehicle may be obtained. Impeller 653 is preferably of brass or a material such as polystyrene or other synthetic resin, and the body 635 of steel, polystyrene or other synthetic resin. The cone 632 is preferably of a cellulose acetate butyral material, and is folded as shown to make a thin sound producer possible. In use the sound generator is mounted between a road wheel 622 and the fender 627 of the vehicle, and is brought into use by operating a control handle so that resilient rod 657b moves friction wheel 656 against road wheel 622 and biases it against it. The movement of frame 652 involved also brings impeller 653 into contact with the body 635, so that when wheel 622 rotates the sound generator emits a sound similar to that of a motor vehicle.

Filed: 1968-08-13
Abstract: 1283354 Transformers and inductors MIDLAND TRANSFORMER Ltd 12 Nov 1969 [13 Aug 1968] 38580/68 Heading HIT A coil for a variable transformer, choke or motor starter with an outer surface which is traversed longitudinally by movable tapping contacts is made from a number of preferably identical elements 10, 11 spirally wound from strip of rectangular section and assembled side by side, with alternate elements rotated so that their turns spiral in the opposite sense. A series winding is then formed by interconnecting the starts such as 13, 15 of alternate pairs of adjacent coil elements e.g. 21-22, 23-24 by means of longitudinal bars 28, 30 within the coil and by interconnecting the finishes of the remaining alternate pairs of adjacent elements as at 27, 29. The finishes may project radially from the coil as at 14, 16 and be strapped together, or they may be joined edge to edge to form smooth transitions as shown in Fig. 4. The coil elements may be rectangular so that a flat coil surface (see Fig. 5) is presented to a brass and a carbon roller or brush contact connected in parallel. Alternate coil elements 36, 38, 40 have portions adjacent their finishes 54, 55 which extend right across the coil face as at 48a, 48b and 46a, 46b whereas intervening elements 37, 39 have portions extending only half way across the coil as at 47. Broad insulating strips 49 prevent the brass roller from bridging coil elements as it travels along a longitudinal path between lines 51, 52 while the carbon contact travels along a similar path between lines 51, 53 and bridges adjacent coil elements across narrow insulation strips 50 to preserve continuity of supply. The tapping contacts may move in synchronism or in a stepwise manner, preferably with snap-action to prevent overheating of the carbon contact.

Title: Apparatus for testing hearing
Inventor: TOWNE ARNOLD PHILLIP
Filed: 1960-11-10
Abstract: An apparatus for testing hearing transmits intelligence to the patient and comprises means for comparing his response with that of a person with normal heating, in which the intelligence is transmitted partly to one ear and partly to the other, so that unless both parts are heard the signal becomes unintelligible.  In the embodiment described the signals are divided between two tracks on a magnetic tape, a third track is used to give signals which cause the lighting of instruction lamps and the fourth track carries signals which cause the stepping forward of a record card. As the tape is run through the testing equipment the patient is instructed to perform certain operations, such as pressing buttons according to the information received, part of which is received by one ear and part by the other. The third track causes the lighting of a signal lamp at the instants when these actions are to be performed but unless both ears have received their information the response will be incorrect or impossible.  The intensity of the sounds to each ear is increased in predetermined steps from the level at which they would be heard by a normal ear, so that the level at which the signal becomes intelligible in each ear can be determined.  Pressing the various buttons by the patient actuates electromagnetic punches to perforate a record card in accordance with his responses and the positioning of the card is controlled by signals carried on the fourth record track.

Abstract: 1,065,333. Transistor oscillator inverters. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 21, 1965 [Sept. 23, 1964], No. 40187/65. Heading H3T. [Also in Division H2] An inverter supplying two or more discharge lamps 19, 20 comprises a thyristor 5 (or 13), an inductor 6 (or 14), and a circuit 8, 9 consisting of a capacitor and an inductor in parallel, connected in series across a D.C. source 1, 2. The circuit is oscillatory with less than critical damping and the ratio of the second inductance to the first is less than fifteen and preferably less than ten. The load is a number of independently switchable circuits each of which is capacitive at the operating frequency of the inverter, such as a capacitor and a fluorescent lamp in series. The apparent power of the capacitor is between 1À3 and 1À5 times that of the lamp. Part of coils 6 and 14 may be replaced by a coil between 1 and 12. Firing signals for the thyristors are taken from the secondaries of transformer 44 connected to the inverter output through capacitor 43 and inductors 42, 45. The transformer has a square loop ferrite coil which produces a pulse each time the oscillation passes through zero. Starting circuit.-When switched on the full supply voltage appears between points 4 and 27 and charges capacitor 28 through resistors 29, 30 and voltage divider 31, 32. The voltage of the emitter of transistor 33 becomes increasingly positive until it exceeds the base voltage determined by the resistors 34, 35. The transistor 33 conducts and capacitor 28 discharges through resistors 36, 37 until capacitor 39 becomes charged by the current through the base of the transistor and the secondary winding of transformer 38. A pulse voltage then appears across resistor 37 and fires the thyristor 13. Diodes 40, 41 then switch off the starting circuit.
