Title: Improvements relating to aeroplanes
IPC: B64C13/00
Filed: 1937-10-27
Abstract: 504,788. Controlling aircraft. ROE & CO., Ltd., A. V., and CHADWICK, R. Oct. 27, 1937, Nos. 29321 and 29322. [Class 4] Aircraft wing-flaps or lift-increasing devices are operatively interconnected with flaps upon the tail plane or elevators in order to maintain the longitudinal trim of the aircraft on operation of the devices. In one form, the flaps are operatively interconnected with flaps disposed on the lower or upper surface of the tail plane and are moved on actuation of a hydraulic jack. In a modification, the flaps are further interconnected with the elevators ; in this case the flaps may be operated by separate jacks conneated in the same circuit. The flaps bare pivoted to links n, o, the link on being carried by a torque tube m having arms k. The arms k are pivotally interconnected by the splayed end of a slotted lever j connected by links p and arms q to the torque tube which moves the elevator. The flaps b are normally adjusted through a rocker lever h and an arm i engaging the slotted lever. Thus, if the elevator is moved with the flaps b extended the flaps are returned to their normal position. In further forms, the wing flaps are interconnected with trimming tabs on the elevators or normally nested flaps disposed on the elevators. In the latter case, raising the elevator retracts the flap whereas lowering the elevator depresses the flap still further.

Patent GB-193920-A (GB)
Title: Improvements in or relating to machines for cutting the teeth of worm wheels
IPC: B23F11/00
Filed: 1921-11-05
Abstract: 193,920. Brown & Sons (Huddersfield), Ltd., D., Shaw, F. W., and Kitchen, H. E. Nov. 5, 1921. Gear-cutting.-In a machine for cutting worm wheels a bobbing cutter is first fed radially into the work at a rate which changes automatically so as to equalise the cutting strains and at a predetermined point the radial feed is automatically disengaged and the cutting is completed by a varied. tangential feed of the hob compensating differential mechanism being provided in the driving gearing to operate while the tangential feed is in operation. If desired either the radial or the, tangential feed may be used alone. In the form shown the cutter head 1 movable radially of the blank 3 on a bed 2 carries a tangentially movable hob slide 4 operated from a screwed shaft 28 carrying oppositely rotating bevel gears driven from a shaft 11 and controlled from a clutch 29. The shaft 11 is driven from a driving shaft 6 through change gears 7 driving sleeve, 8 and worm gearing 9 and carries a pinion 12 driving a worm 14 mounted in a pivoting box 21 and engageable by means of a hand lever 22 with a worm wheel 15 on a vertical shaft 16. The latter carries at its lower end an eccentric pin 17 which works in a die 18 in a slide 19 adjustably locked to the bed 2. When the worm 14 is engaged the pin 17 thus operates to impart radial feed to the cutter head 1, the initial position of the pin being so adjusted that only that portion of the motion immediately preceding the inner dead centre is utilised to give the required depth of cut so that a gradually decreasing rate of feed is obtained. When the radial feed is completed the worm box is operated automatically and a spring pressed bar 33 normally abutting against a projection on the worm box and connected through lever mechanism 34 to the clutch operating rod 30 is pressed forward to engage the tangential feed. At the end of a predetermined tangential travel a rod 42 engages the bar 33 to return the clutch to a neutral position. In order to compensate for the tangential movement of the hob a gear 40 from the shaft 28 operates a shaft 41 passing through the sleeve 8 and connected to differential gearing. To provide variable tangential feed the driving gearing may be modified as shown in Fig. 5. The constant mesh gears 7 are selectively engaged by means of a sliding key 46 operated by a pinion 45 on a shaft carrying a cam disc 47 rotatable by a weight 52 but normally held by a pivoted catch lever 48 carrying a pressure plate 50 coacting with a projection 51 on the hob side. In operation as the projection 51 is traversed the lever 48 is swung about its pivot to clear successively the projections 47<1> and allow the pinion 45 to rotate to bring the gears 7 into succesive operation. Interlocking means may be provided to prevent the radial feed from being engaged when the cutter head is locked to the bed and for locking the differential drive while the radial feed is in operation.

Title: Flexible drive coupling for rotary pumps and other purposes
IPC: F16D3/72
Filed: 1938-10-12
Abstract: 522,472. Universal joints. FULCHER, F. C. Oct. 12, 1938, No. 29556. [Class 80 (ii)] The shaft 12 of a rotary-vane pump is driven from a shaft 18, loosely telescoped within a bore 17 of the shaft 12 and splined to or having a tongue-and-groove connection with an enginedriven shaft, by means of a rectangular laminated blade 21, one end of which engages in a diametral slot 20 in the shaft 18 and pivots about a pin 22 while the other end engages in a diametral slot 24 formed in the shaft 12 at the base of the bore 17 and pivots about pin 28. The outer portion of the slot 20 is wider than the inner portion, in which the blade 21 engages, so as to provide clearances 23 permitting limited flexure of the blade, while the gap 29 between the end of the shaft 18 and the base of the bore 17 permits unrestricted flexure. The walls 46 of the outer portion of the slot 20 may be plane or may be curved, as shown in Fig. 8, to correspond to the twisted form which the blade 21 assumes under torque. Alternatively, the slot 20 may be of the same width throughout, shims being provided between the blade and the inner portion of the slot so as to provide the clearances 23. The flexibility of the blade may be varied by replacing one or more of the laminations by spacing washers, Fig. 5, or by forming longitudinal slots in one or more of the laminations. Specifications 522,470, 522.471 and 522,473, [all in Group XXVI], are referred to.

Title: Four channel record reproducing apparatus
IPC: H04S3/00
Filed: 1971-06-24
Abstract: 1346078 Four channel stereo systems NIPPON VICTOR KK 24 June 1971 [26 June 1970 5 July 1970 (2) 1 Sept 1970 22 May 1971] 29625/71 Heading H4R In a four. channel record reproducing apparatus for reproducing signals from a record of the type described in Specification 1,337,397, i.e. where a sum signal derived from two channels is recorded direct and a difference signal of the two channels is recorded as angle modulation of a carrier in a frequency region above the range of the direct signal, a control voltage is derived by detection of the angle modulated carrier and used to operate various circuits, e.g. to illuminate a four track indicator light, to enable or mute the channels supplying the rear speakers in the reproducing system, and to modify the frequency response of the reproducer channels to cater for the falling top response of the four track system. As described with respect to Fig. 1, in which the equipment for only one pair of channels is described, the directly recorded signal, up to 15 kHz is extracted by a 15 kHz low pass filter 13, amplified and applied to a matrix circuit 16. Similarly the angle modulated signal is extracted by 20 kHz to 50 kHz band pass filter 14, amplified, limited, demodulated, filtered, and applied to the matrix circuit 16, via a muting circuit 22, an equalizing amplifier; and an expander if a compressor has been employed during recording. The carrier of the angle modulated signal is detected by an amplifier 19, sharply tuned to 30 kHz, rectifier 24 and level detecting switch circuit 25. The switch circuit operates an indicator lamp 26, makes the muting circuit inoperative, and affects appropriate adjustment of the frequency compensating circuits 29a and 29b in the outputs from matrix circuit 16, on detection of the carrier signal. Circuits for the carrier signal detector, muting circuit, indicator circuit and frequency compensation circuit are described with respect to Figs. 3, 5, 8, and 9 (not shown). It is suggested that the frequency compensation circuits can be employed on the input to the matrixing circuit 16, when only one will have to be switched due to muting of the other channel.

Abstract: 846,941. Circuits employing bi-stable magnetic elements. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Aug. 27, 1958 [Sept. 20, 1957], No. 29636/57. Class 40 (9). [Also in Group XIX] A stage of a binary counter comprises two cores A, B linked by rectifier circuits. Terminals P2 are fed with control pulses and terminals P1 with pulses to be counted. A P2 pulse follows each P1 pulse. The circuit from terminals P1 includes winding a-on core B, and parallel paths through opposed windings b, c and rectifiers D1, D2. Winding g on core A is included in one of the parallel paths. The circuit from terminals P2 includes opposed windings e, f on core A and a single winding d on core B. Core B carries an output winding o. Windings d and g have more turns than windings b, c, e, f which themselves have more turns than a. One output pulse appears on terminals PO for every two input pulses on P1. Assuming the initial state of cores A, B to be (1,1) a cycle of operations is (11)P1(01)P2(01)P1 and P0(00)P2(11). Only positive pulses are effective at P1 and only positive pulses from P0 are effective in a cascade. Thus an output pulse accompanies the change (01)P1(00). Alternate control pulses P2 are ineffective. When arranged in a cascade, each pair of cores 1A, 1B or 2A, 2B, Fig. 2, may be linked to the next pair by a third core 1C or 2C. The pulses on terminals P1 are then accompanied by two series of control pulses on terminals P2, P3, the pulses occurring in the sequence P1, P2, P3, P2, P3, P1, as shown at the foot of Fig. 2. With two stages, an output pulse appears on terminals P0 of winding 2m of core 2C once in a cycle of four P1 pulses.

Abstract: 840,230. Gravity railway systems; marshalling vehicles. SIMON-CARVES Ltd. July 10, 1958 [Sept. 23, 1957], No. 29789/57. Classes 78 (4) and 104 (2). A system for moving wheeled vehicles comprises track sections which can he raised at one end by hydraulic jacks to cause vehicles resting thereon to move along the track by gravity. In the arrangement shown in Fig. 1 a track section 4, pivoted at 5 at one end and normally resting on a fixed beam 2 at the other, can be lifted at one end by an hydraulic jack 3 to cause a railway wagon resting thereon to be moved on to a track section 10. A track section 6, pivoted at 7 and resting on a fixed beam 9, can be raised by a jack 8 to stop wagons on section 11 entering the section 4. In a modification, shown in Fig. 2, a track section 14, provided at its ends with pivots 15, 16 nesting in bearings 17, 18, can be lifted at each end by hydraulic jacks 19, 20 which are inter-locked so that only one end at a time can be lifted. In the arrangement shown in Fig. 3, railway wagons can be moved from a track 11 to a track 21 by the sequential raising and lowering of the various sections therebetween. The wagons are held stationary by a track section 6 held in the raised position by an extended jack A. The end of track section 4 is also raised by an extended jack B. When an operator actuates a control to retract jacks A, B the wagons move forward until the first wagon operates a track switch H to extend the jacks A, B to stop the following wagons. The wagon on track-section 4 now moves forward by gravity to operate a track switch J to retract a jack F and to extend a jack C to move the wagon to the next track section. The wagon then operates a track switch K to retract the jack C and extend a jack D to move the wagon to the next track section which is similar to that described with reference to Fig. 2. The wagon now actuates a track switch L to retract jack D and to extend a jack E to move the wagon over a switch M, which retracts jack E and extends jack F on to the track section 21 which may be part of a tippler or weigh-bridge. The jacks may be operated by remote control. Channels instead of rails may be used for moving road vehicles.
