Title: Apparatus for recording and reproducing sound
IPC: G11B3/00
Filed: 1928-07-23
Abstract: 320,431. Stephens, A. J., (Leeming, H. T.). July 23, 1928. Ribbon machines; feed mechanism; records, materials for. - Relates to sound-recording and reproducing machines of the kind employmg a record in the form of a flexible band. According to the invention, the mechanism is so arranged that both sides of the record band can be used without it being necessary to change the band with respect to the driving and grinding mechanism. The machine described embodies two electric recorders or pick-ups, acting simultaneously on the inner and outer sides respectively of an endless band of metal, preferably thin aluminium. The band 11 passes over rollers 12, 13, and is driven by a roller 21 on a shaft 23, which is rotated by a motor-driven shaft 5 through a worm wheel 24. A spring-pressed idler 21a opposes the roller 21. Located as shown are feed screws 32, 48, by means of which stylusheads 38, 45 are traversed across the band, the screws being driven by gearing such as 26, 27, 30, 31 from the shaft 23. Each stylus-head is mounted on an arm 37, pivoted on a guide shaft 33 and engaging with a feed arm 34. The latter is also pivoted on the shaft 33 and is held in engagement with its screw 32 or 48 by a weight 36. Each recording or reproducing stylus bears on a part of the record band supported by a roller 40. The bearings of the roller 12 are adjustable, to enable the band to be made taut. When the band is to be replaced, the rollers 12, 13 &c. can be slid along their shafts, away from the frame 14. Recording and reproducing may be effected purely mechanically, instead of by electric means.

Title: Improvements in and relating to electric cooking apparatus
IPC: A47J37/06
Filed: 1935-07-29
Abstract: 441,258. Cooking-apparatus. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. July 29, 1935, No. 21514. Convention date, July 28, 1934. [Class 28 (i)] A cooking-device with two electrically-heated plates 10, 11, has the plates connected by hinge means so that they can be supported in substantially parallel relation at various distances apart and so that the upper plate may be moved to a vertical open position with respect to the lower plate and also to a second open position in which it is supported in substantially the same plane as the lower plate. The plates 10, 11 are detachably secured in the casings of the device by spaced lugs 15 on the plates entering apertures in the rear wall, the front end of each plate being locked by a spring-pressed pin actuated by a handle 24 secured to the frame engaging in a recess in the plate. The plates are heated by elements 25, 26 preferably of the type described in Specification 144,767, [Class 37], arranged as shown in Fig. 2, the terminals of these elements being connected to terminal pins 30. The leads 32 for the upper element pass out through the rear of the upper .casing 12 and thence downwardly into the lower casing 13, the exposed portion of the leads being preferably covered by a flexible conduit 33 that can slide inwardly into the upper casing. The hinge means comprises a pair of rigid L-shaped lugs 38, with the long legs of the L secured to the inner side walls of the upper casing 12, pivotally secured to L-shaped links 41 pivotally mounted within the lower casing 13 adjacent its front wall. The bottom and the side wall of the casing 13 are slotted to receive the links 41 and to provide for limited vertical movement thereof. The lugs 38 are extended to form abutments 47 to engage the rear wall of the legs 14 attached to the casing 13 when it is desired to use the device with the upper plate approximately vertical. A handle 48 is secured by a pivot 51 to a bracket 49 at the front of the casing 12 ; a spring arranged in the handle permits it to be locked in a recess 59 to maintain it in a position at 180‹ from its normal pendant position, the handle when locked in this recess serving as a leg to support the upper plate after that plate has been swung to an open horizontal position. The lower plate 11 is provided with a sump 60 fitted with a draining pipe 61.

Abstract: 628,680. Hand saws. PURNELL, E. W. Aug. 7,1947, No. 21614. [Class 61(ii)]  A hack saw frame is adapted for cutting circular holes in sheet material, e.g. in water tanks, the blade being traversed in a circular path while the back of the frame acts as a centre guide. The back 1 of the frame is of circular section. The front arm 2 has a series of slots 15 at determined intervals, in any one of which the headed end of a saw blade or cutting file 12 may be. engaged. The rear arm 3 is flatted at 4 and receives a slide block 6 which can be secured in adjusted position along the arm by screwing up the handle 5, and carries a slotted and reversible blade holder 13 and tensioning nut 11. In use, a guide hole is drilled in the sheet of material at the centre of the circle which is to be cut out and a second, smaller hole at the desired radius. The back 1 and arm 2 of the saw frame are passed through the guide hole and a saw blade or file is passed through the other hole and engaged in the appropriate slot 15, its other end being engaged in the holder 13 with the block 6 adjusted appropriately. The frame is then reciprocated while the blade is turned gradually about the axis of the frame back.

Title: Improvements relating to aircraft
IPC: B64C27/02
Filed: 1935-07-31
Abstract: 460,634. Aircraft with rotary-wing systems. KAY GYROPLANES, Ltd., KAY, D., and DYER, J. W. July 31, 1935, No. 21761. [Class 4] In aircraft of the type supported wholly or partially by an overhead system of blades or wings rotatably mounted upon a vertical or substantially vertical supporting member or mast, the rotor supporting member is so mounted and arranged that when it is tilted laterally or laterally and longitudinally its point of support or pivot is caused to move relative to the aircraft either to keep the centre of lift of the rotor system in the same, or substantially the same, position relative to the centre of gravity of the aircraft or to vary this position by a predetermined amount. Fig. 2 shows a mast B carrying a rotor A which has been tilted for the purpose of lateral control and of which the mast support C has simultaneously been moved in' the contrary direction in order to maintain the centre of lift D vertically above the centre of gravity F. The invention is described as applied to the rotor supporting member and mounting described in Specification 442,016. In this construction, Figs. 3 and 5, lateral tilting of the rotor support 1 is effected by rotating in one direction or the other axle 7 of zed-crank barrel 6. Lateral bodily movement of the mast is effected by axial movement of axle 7. The means for producing the latter movement comprise a drum 39 secured to side wall 40 of rotor supporting bracket 10. Drum 39, Fig. 7a, is formed with oppositely disposed helical slots 48, 49 in which engage rollers 50, 52 carried by a transverse pin 47 secured in jaws 45, 46 formed at one end of axle 7. By selection of,the slope given to slots 49, 50 the bodily movement of mast 1 which is caused to accompany its tilting movement may be made either more or less than that shown in Fig. 2, and if made greater an unbalanced couple is produced acting in the direction G<1> tending to assist the banking of the aircraft. As described in Specification 442,137, means may be provided for adjusting either on the ground or in flight the position of block 14, Fig. 3, on the pin 13. It is stated that when block 14 is at any position other than central the end load on link 18 will cause rotor support 1A to have a tendency to tilt laterally whereby the lateral control of the aircraft mav be given a bias. In a modification the zed-crank barrel is turnably mounted on its axle and actuated by means of a lever and link connected to a single operating member, to which member is also connected a link associated with a lever serving to turn the axle, the point of connection of the latter lever to the operating member being adjustable whereby the ratio of the lateral movement of the point of support of the rotor mast to the amount of tilt thereof may be adjusted. Specification 285,213, [Class 114], also is referred to.
