Title: Gramophone for a toy figure such as a doll
IPC: G11B33/06
Filed: 1975-04-23
Abstract: 1501435 Spring driven gramophone STELCOSPIELWARENFABRIK STELTER GmbH & CO KG 23 April 1975 [16 Nov 1974] 16865/75 Heading G5R In a spring driven gramophone for mounting in a toy figure in which a record carrying spindle 27 is driven by spring motor 24 via gear 18 and pinion 26 and carries a further gear 31 coupled via idler gears 32, 33 to speed controlling flywheel 36, the spindle is tiltable and the inertia of the flywheel acts when the spring motor stops to move gear 31 away from the idler gear thereby tilting the spindle and allowing the pick-up arm 7 to disengage from the record and be returned by spring 5 to a position over the start portion of the record groove. The upper end of the spindle 27 is supported in a slot 29 in member 28 and the slot extends parallel to the periphery of drive gear 18 where it engages pinion 26 so that even when tilted the spindle remains in drive engagement with the motor. The motor stops when ring 21 at the end of its winding pull cord is engaged in an aperture in the gramophone casing. The apex 9 of the loud-speaker diaphragm is urged into engagement with the pick-up arm by spring 16 and the flywheel can be the eccentrically weighted element shown or can comprise a resilient member, Figs. 6 and 7 (not shown), with a pair of parallel slots which allow parts of the member to be moved outwardly by centrifugal force into braking engagement with the inner surface of a cylindrical member.

Abstract: 975,935. Change-speed control. HUMBER Ltd., and D. HODKIN. May 8, 1961 [May 13, 1960], No. 16917/60. Heading F2D. In a change-speed control for motor vehicles, wherein a three or, as described, four forward speed and reverse synchro-mesh main changespeed gear is arranged in series with an auxiliary change-speed gear such as the two-speed direct overdrive gear described, and a shaft 14, manually actuated by a steering column or main gear-box mounted control, is partrotated for cross-shift selection and then axially moved to establish a selected ratio in the main gear, subsequent, further part-rotation of the shaft 14, when the main gear is in top, or in one of the top two gears, also actuates, without change in the main gear, an electric push-button switch 32 whereby a selected ratio, e.g. overdrive, is engaged in the auxiliary gear. The shaft 14 comprises an arm 12 for engagement in notches of the shift rods. A safety member 16, rotatable, but not movable axially, with the shaft 14 and preventing simultaneous operation of two shift rods, comprises arms through holes in which the shaft 14 passes, a cross-bar 16b having longitudinal slots 18 receiving the arm 12, and further arms 16a embracing the arm 12 when the latter is in neutral position, and is axially located by an end wall and a flange of the main gear-box. The switch 32 is mounted in the gear-box wall and is actuated by a projection 34 on the safety member 16. An adjustable, spring-loaded ball detent 26 mounted in the end wall is respectively engageable in recesses 27, 28 of a plate 24 of the safety member 16 in the rotational shaft 14 position for main gear cross-shift selection for third and fourth gears and in the rotational shaft 14 position for overdrive engagement. A gear-box abutment 35 engageable by a safety member arm 16a, limits rotation of the arm 12. A further gearbox abutment 36 at the neutral axial position of the arm 12 co-operates with a peg 38 thereon to prevent axial movement of the arm only when it is in the further part-rotational position for overdrive engagement, thereby necessitating the disengagement of overdrive before a change between, or from, third and fourth gear can be made.

Abstract: 322,417. Dreyfus, H. June 12, 1928. Fibres, stapling.-In the production of staple Fibre from artificial filaments or threads either continuously with their formation or when drawn from bobbins or other packages the filament is conveyed by a current of air or other fluid generated by a fan or impeller to a cutting-device operating in conjunction with the fan &c. The cutting-device may itself act as the fan. The cutting-device and the fan &c. may be driven by an electric motor or may be carried by the motor, and their speed is adjustable to suit the rate of production of the filament or to vary the length of staple produced. Suitable guides or supports such as driven rollers may be provided to diminish friction between the filament and the walls of the enclosing conduit. The filament is drawn along a conduit 6, Fig. 1, into a conduit 8 by a fan 12 mounted on a shaft 9. The shaft 9 is supported in bearings 10, 11 and also carries a cutting-device 14 comprising knives 15, which move past a stationary blade mounted round part of the edge of the orifice 7 from the conduit 6.

Title: Method of producing p-and m- nitrobenzoic acids
Inventor: KOCHERGIN PAVEL MIKHAILOVICH
IPC: C07C205/57
Filed: 1964-04-24
Abstract: Meta- and para-nitrobenzoic acids are prepared by oxidizing a mixture of isomers of aromatic compounds having both a -NO2 group and a single group incorporating oxygen or halogen oxidizable to a -COOH group attached to the ring in the m- or p-position with respect to the -NO2 group, with diluted nitric acid to a mixture of isomeric nitrobenzoic acids and fractionally crystallizing the mixture of acids or salts thereof. The preferred crystallization procedure is based on the low solubility of p-nitrobenzoic acid in aqueous isopropanol and the low solubility of calcium m-nitro-benzoate in water.  In examples the following starting materials are used: nitro derivatives of phenylmethyl carbinol, alphachloroethyl-benzene or acetophenone, nitric esters of nitrophenylmethyl carbinols and mixed nitro compounds obtained as a by-product in the preparation of p-nitroacetophenone.

Title: Improved methods of and means for converting the energy of nuclear radiations into useful electrical energy
IPC: G21H1/06
Filed: 1954-06-10
Abstract: 761,404. Semi-conductor devices. RADIO CORPORATION OF AMERICA. June 10, 1954 [June 30, 1953], No. 17130/54. Class 37. [Also in Group XL (a)] An electrical device comprises a semiconductor body having a potential barrier region which is irradiated by emissions from a nuclear source to provide a potential between output contacts on either side of the barrier. In the examples described, a PN junction in a germanium or silicon body is irradiated by nuclear emission, which produces electron-hole pairs in the material; the carriers produced in the neighbourhood of the junction flow across the potential barrier existing thereat to make the P region positive relative to the N region, so that a current is produced in an external circuit. Carriers produced adjacent the junction region may flow to the region by diffusion and thus contribute to the current. In Fig. 1, emission from nuclear source 11 penetrates the semi-conductor body 13 comprising a PN junction 15, to produce current in load 21. In Fig. 4, several semi-conductor bodies are positioned so that emission from source 11 is normal to the PN junctions and penetrates them sequentially until absorption is complete. The outputs are connected in parallel or the bodies may be arranged to contact each other to provide a series output, Alloy-diffusion junction, or grown PN junction, or point contact devices may be used. Fig. 9 shows four series arrangements connected in parallel, surrounding the source 11 of nuclear emission, which is insulated from the semiconductor bodies by insulating layers 39. The junctions 41 and 43, which would tend to provide a potential in opposition to that of the remaining junctions, are effectively destroyed by sandblasting or copper plating. The nuclear source may be coated on or placed in contact with one of the semi-conductor regions and used as an electrode. In an alternative arrangement, the P and N regions are in the form of concentric hollow cylinders surrounding the nuclear source. The device may be used to energize transistors. The nuclear source may emit charged or neutral particles, and may consist of polonium, uranium (for α particles), strontium 90, tritium (for # particles) or cobalt 60 (for y rays).
