Title: Improvements in variable speed power transmission mechanism
IPC: F16H47/12
Filed: 1933-12-29
Abstract: 430,925. Variable speed gearing; hydraulic couplings. WHARTON, W., The Gables, Kendal, Westmorland. Dec. 29, 1933, No. 36585. [Class 80 (ii)] [See also Group XXIX] A variable-speed gear particularly applicable to motor vehicles comprises an adjustable hydraulic coupling A, and anon-adjustable coupling B, the two couplings having a common casing 2, and controlling an epicyclic train 8, 9, 9<x>, 10. The sun-wheels 8, 10 are fixed to the driving shaft 3 and the driven shaft 11 respectively, while the planet carrier 13 is connected through a sleeve 14 to the rotary arms 15 of the coupling B. The arms 15 carry paddles 16 geared through pinions 18 to toothed rings 19 on the casing 2. The vanes 7 of the coupling A are pivoted on a disc 6 fast on the driving shaft 3, and are adjustable by arms 23 on a nut 22 carried on a screwed sleeve 20 which is splined on the driving shaft 3 and urged axially by a spring 25, so as to tend to force the vanes 7 outwards towards the position of minimum slip in the coupling A. The casing 2 carries a claw member 29, Fig. 4, having a combined spiral and undercut contour to mesh with a corresponding member 28 abutting against a shoulder 33 on the sleeve 20 and connected by a ratchet clutch 35 to a fixed member 37. At rest or low speed the reaction on the planet carrier 13 is taken up by the coupling B, thus tending to rotate the casing 2 backwards. The slight permissible movement causes the claws 28, 29 to move relatively to each other and thus move the sleeve 20 axially so that the coupling A is inoperative, further movement being prevented by the ratchet clutch 35. As the load on the driven shaft decreases, the slip in the coupling B decreases and the casing 2 will finally tend to rotate forwards. The spring 25 can now force the vanes 7 into operation, and an additional forward drive is transmitted through the casing and the coupling B to the driven shaft. As the load further decreases, a solid drive is approached. Specification 192,244, [Class 69 (ii)], is referred to.

Abstract: 1,236,283. Aircraft. P. WILLEMS, [trading as PHYSIK. - CHEM. FORSCHUNGS - INSTITUT PROF. P. WILLEMS]. 1 Aug., 1968 [8 Aug., 1967], No. 36663/68. Heading B7G. Passenger saving apparatus in an airplane comprises a survival cell, means for hermetically closing the cell, a plurality of connecting means between the cell and the airplane suddenly and simultaneously releasable by an electric circuit having at least one manually operable switch, feeding and control means leading from the cell to the plane and safety couplings to close up and separate the feeding and control means upon release of the cell, at least one means secured to the cell to reduce its free fall speed after release, and independently usable emergency equipment including at least one emergency current unit, a driving and control device for movement in water and a signalling device. In one embodiment the cabin of the aircraft 2b constitutes the survival cell. The wings 1 and tailplane being releasably detachable by connections 3. A roof canopy 2d is also ejectable to permit funnelled parachutes to open. The parachutes, attached by elastic carrying cords, may each constitute string of such with a drogue parachute carrying signalling apparatus. The detachable parts of the plane may be connected to the plane by motor driven bolts, the motors being activated by closing the electric circuit. In this circuit a master switch has to be operated to uncover two further switches (for pilot and co-pilot) which when thrown retract the bolts and release the survival cell. In an alternative embodiment (Fig. 10), the cabin 26 of the aircraft is releasably suspended within an outer body 25. Parachutes 4 and a balloon 31 are stored in a headspace betwen cabin 26 and body 25. If desired, the umbrella of each parachute may be formed as a balloon. In a compartment beneath the floor of the cabin 26 are stored gas bottles 28. When the cabin 26 is released from body 25 the valves of bottles 28 are opened and the gas fills the balloon(s) via conduit 30. For movement through water the cabin 26 may be provided with a keel, centre board and either screw or water jet propulsion means. Emergency supplies such as radio beacons and distress signals are supplied, together with an emergency electrical supply. As an alternative a rocket or rockets may be used to reduce the free fall speed of the cell. The aircraft may, of course, comprise a plurality of such cells each with their own descent equipment. When the cell or cells are released from the aircraft the power cables and control pipes tear apart and automatic valves shut to prevent leakage of gas (e.g. oxygen) from the cell.

Dec. 28, 1934, No. 37156. [Class 80 (ii)] [See also Group XXII] In a portable device for screwing-up nuts and screws, two intercoiled springs 21 are attached at 22, 24 to a driving disc 19 and a tubular hammer 20 respectively with initial compression to effect a yielding driving connection. A nut wrench 31 or a screw-driver &c. is rotatably mounted in the casing 15 by a flange 30, the adjacent faces of the wrench &c. and hammer being provided with clutch teeth 34, 28 which are bevelled so as to slip on overload. As the resistance of the nut &c. to turning increases, the springs 21 are placed under additional torsion and compression until the clutch teeth 28, 34 slip, whereupon the springs unwind and the hammer 20 delivers a torsional blow to the wrench. A further spring 27 seated on a pin 26 acts as a cushion in an axial direction between the hammer and the disc 19. The wrench 31 and hammer 20 need not be exactly co-axial.

Title: Improvements in loud speakers for wireless telephony
IPC: H04R3/00
Filed: 1929-12-09
Abstract: 342,070. Loud - speakers. LUCAS, O. D., 49, Linden Gardens, Notting Hill Gate, London. Dec. 9, 1929, No. 37734. [Class 40 (iv).] The coil of a moving-coil loudspeaker is centretapped and continuous current is passed in opposite directions through the two halves of the coil for damping its movements. As shown the coil 1 is connected in the output of an amplifying valve 6 through a choke-capacity coupling, the capacity being divided into two portions 7, 8 separated by a further choke 4 across which is connected the whole of the moving coil 1 and a resistance 5. The resistance 5 equalizes the current in the two halves of the moving coil, obtained from a high-tension source, through a controlling resistance 3 and a choke 2 connected to the centre-tapping. In a modification the speech potentials are delivered from a transformer to the condensers 7, 8 (Fig. 2, not shown) and in this case the condenser 8 may be omitted. In other modifications (Figs. 3 and 4, not shown) the negative pole of the d.c. source is connected to a centre-tapping on the choke 4 or to the join of two similar chokes in which case the resistance 5 is omitted. In the above examples the two halves of the moving coil are wound in the same direction. Alternatively they may be wound in opposite directions, the direct current being applied to the extremities, and the speech current to the centre-tapping.

Title: Improvements in or relating to the reproduction of a recorded television signal
IPC: H04N5/06
Filed: 1961-10-20
Abstract: 937,691. Television. AMPEX CORPORATION. Oct. 20, 1961 [Nov. 28, 1960], No. 37802/61. Class 40 (3). In a system for regenerating the synchronizing and blanking portions of a composite television signal from, for example, a magnetic tape recording, there is provided means for delaying the video portion of the signal (by an amount equal to the delay produced in the synchronizing pulses when they are separated from the composite signal), means responsive to the separated synchronizing signals for reproducing horizontal and vertical blanking pulses delayed respectively by one line and one frame periods, and means for reinserting the delayed blanking pulses and regenerated synchronizing signals in the delayed video portions in the correct time sequence. If the composite signal includes colour information this may also be delayed and reinserted. The general procedure (Fig. 1, not shown) is to demodulate the frequency modulated recording, separate the synchronizing pulses from the video portion in an R.F. type separator and to apply the video portions, the synchronizing signals and any colour information to a circuit which effectively removes the old blanking and synchronizing signals and regenerates new waveshapes. In this circuit (Fig. 2) the separated synchronizing pulses are applied to a plurality of regenerating circuits. One such circuit for regenerating the horizontal blanking signal comprises the fixed delay phantastron 28, the variable delay phantastron 30, each of which delays the input signal by one half the line period, and the monostable multivibrator 34 triggered by the trailing edge of the output pulse from the phantastron 30. The width of the horizontal blanking pulse so generated is adjustable. Similarly a further such circuit for regenerating the vertical blanking signal comprises a pair of phantastrons 41, 43 each producing a delay of one half of a frame period and a monostable multivibrator 46 for producing the vertical blanking signals, this circuit also including the integrator and amplifier 40. The outputs from the multivibrator 34 and 46 are applied to the cathode follower " OR " gate 37, then to diode adder 50 and then to circuit 55 for reinsertion in the video signal. The separated synchronizing signals are also applied to the keyed clamp 25 to provide D.C. restoration of the video signal and to amplifier 22 which re-forms the synchronizing pulse itself. The video portion of the signal after being suitably delayed by circuit 20 is applied to the adding circuit 55 where the reinsertion of the various parts of the composite signal in correct time sequence is accomplished. Colour burst is added at this point, being generated by generator 60 and suitably delayed and amplified by delay circuit 61 and amplifier 63, respectively.
