Title: Pulse delaying circuit
IPC: H03K5/04
Filed: 1962-04-25
Abstract: 1,009,352. Transistor pulse delaying circuits. RADIO CORPORATION OF AMERICA. April 25, 1962 [May 10, 1961], No. 15798/62. Heading H3T. In a pulse delaying circuit of the type described in Specification 1,009,351, the rise time of the output pulse is reduced by the use of positive feedback. As shown, all transistors are initially non- conductive until an input pulse at 18 makes Q2 conductive, reverse-biasing Q1. The input pulse is also fed to the base of Q1 via an integrator C, R. When C has charged sufficiently to overcome the bias on Q1, the conductive states of Q1, Q2 become reversed, the action being made rapid by means of positive feedback via Q4, capacitor 44 and diode 48. Capacitor C is discharged by Q5 and the end of the input pulse, after which all transistors become non- conductive. The negativegoing delayed pulse at the collector of Q1 is  amplified and inserted by Q3, limiting diodes 12, 29 being provided. Diode 19 provides a path for base current when Q1 is non-conductive. Diode 17 isolates the input circuit from the base of Q1 when C is discharging, diode 15 preserving the balance of the input circuit. Capacitor 11 prevents a spike in the output at the trailing edge of any input pulse having a duration shorter than the delay imposed by the circuit.

Title: Restricted differential gears
Filed: 1937-06-11
Abstract: 497,028. Differential gearing. IFIELD, R. J. June 11, 1937, No. 16219. Addition to 471,325.

Title: Arrangement for automatically tuning a radio receiver
IPC: H03J7/30
Filed: 1966-04-13
Abstract: 1,109,335. Automatic tuning arrangements; transistor muting circuits. DOTT. ING. GIUSEPPE GALLO S.p.A. ELETTROMECCANICA CONDOR. 13 April 1966 [9 July, 1965], No. 16264/66. Headings H3Q and H3T. In an automatic tuning arrangement using an electric motor and provided with auxiliary means controlling its starting and stopping, a bi-stable multivibrator is provided, which in one condition releases the auxiliary control means and simultaneously allows energization of the motor. In its other condition it locks the control means and cuts off the current feeding the motor: the passage of the multivibrator from the one condition to the other is controlled by a signal derived from the highfrequency tuned circuits of the receiver, when there arises in those circuits a voltage of an intensity proportional to that of a transmitting station to which the receiver is tuned. Return of the multivibrator from the second to the first condition is effected by means of a manual push-button. The output of the multivibrator is further connected with the low-frequency amplifying circuits of the receiver and, through an adjustable element, with one of the highfrequency circuits, so that it may produce whenever it is in the first condition both silencing of the receiver and a reduction in its sensitivity during the searching period. The receiver comprises R.F., I.F. and detector stages, and first audio stage A, C, and D respectively. A bi-stable multivibrator comprising transistors 41, 46 normally stands with transistor 41 conductive and transistor 46 non-conductive, whereby a positive voltage appears across resistor 42 which biases transistors 57 and 58 and thence transistors 61, 62 non-conductive. Motor 68 is then unenergized and detent 66 is biased by spring 65 into engagement with toothed wheel 64 on the motor shaft. To commence searching, push-button 49 is momentarily depressed, short-circuiting resistor 42 and causing multivibrator 41, 46 to reverse; transistors 57, 58, 61, 62 then become conductive so energizing motor 68 and also magnet 67, whereby detent 66 is withdrawn and tuning permitted to occur. When the receiver becomes tuned to a signal an output is taken from I.F. stage C via capacitor 10 and narrow-band filter F and is applied over amplifier 31 to a rectifier 34, to produce a negative potential across resistor 38 which biases transistor 41 conductive: the multivibrator thereby reverts to its original state and searching stops. During tuning, with transistor 61 conductive a positive bias is placed on the base of audio stage transistor 17, rendering it non-conductive and muting the receiver. This bias also causes diode 4 to become conductive, whereby adjustable resistor 5 is shunted across R.F. tuned circuit 2, 3 and the sensitivity of the receiver reduced during the search. Transistors 57, 58, 61, 62 derive operating potentials from a series diode chain 52, 56, 60 in order to effect temperature compensation.

Title: Improvements in or relating to Steam Plants Provided with Steam Accumulators.
IPC: F01K1/08
Filed: 1919-06-28
Abstract: 129,272. Aktiebolaget Vaporackumulator. June 29, 1918, [Convention date]. Steam regenerative accumulators.-Steam from the main steam supply pipe L1 of a boiler or from the exhaust pipe of a turbine &c. is led on into an accumulator A through a fluid-operated valve G1a so operating that superfluous steam is admitted to the accumulator when the pressure in the supply pipe L1 rises above the normal, and is throttled or entirely cut off when the pressure in the supply pipe falls. When the valve G1a is closed, steam from another source is admitted to the accumulator through a reduction valve R1a. The valves G1a and R1a are so controlled that both are closed when the pressure in the supply pipe is normal, the valve G1a opening and the valve R1a remaining closed when the pressure rises, and the valve R1a opening and the valve G1a remaining closed when the pressure falls. The valves may be mounted on the same spindle, the spindle being operated by the movements of a bellows chamber in communication with the supply pipe.

Title: Improvements in or relating to card record apparatus
IPC: G06K21/02
Filed: 1945-06-27
Abstract: 594,176. Statistical apparatus. WHITSON, J. W. June 27, 1946, No. 16361. [Class 106 (i)] Improvements in the card filing and segregating apparatus of the type described in Specification 362,447 include the provision for automatically effecting alignment of the cards and restraint of selector bar and keyboard operation until the aligning operation has been performed. An electromagnet 53 co-operates with metallic strips 31 on the cards to bring them into alignment when a button switch 120 is depressed. Depression of a switch 54 (Fig. 6, not shown) starts a motor 59 driving a commutator 60 which, through brushes 62, 63 and 64, alternately energizes the magnet 53 and the coils 133 of the selector magnet 72, respectively, the coils 131 being energized continuously while the key 54 is depressed. The magnet 72 is hinged at 139 and is rocked to a horizontal position, against a spring 138, by a member 137 which is oscillated by a link 136 from the motor. These movements ensure the correct selection of cards from the file. Instead of the motor 59, two buttons may be depressed alternately to energize first the magnet 53, then the coil 133, and the rocking of magnet 72 may be accomplished solely by magnetic attraction between the magnet and the cards. The selector bars 15 which are raised by key levers 19 fulcrumed on a bar 20, slide forwards and upwards by the co-operation of slots 16 with bars 17. They are positively returned, and the keys 18 restored, when a magnet 38 is energized by depressing a key 32 (not shown). The armature 42, hinged at 43, engages slots 46 in all the selector bars 15 and thus returns the selector bars and also operates the cutting devices 26 described in the Specification referred to. A bolt 122 prevents movement of the selector bars until, upon depression of a key 120, energization of a magnet 121, Fig. 3, withdraws the bolt from the path of the armature 42. In a modification, the bolt 122, Fig. 9, is bevelled so that it is pushed clear during the restoring movement of the armature 42.

Title: An improved apparatus for generating electrical energy from wave movement of the sea
IPC: F03B13/20
Filed: 1927-06-20
Abstract: 297,720. Parsons, O. H. June 20, 1927. Dynamos, driving.-An apparatus for generating electrical energy from the wave movement of the sea comprises a hollow buoyant body containing a weighted arm rigidly secured to a bevel gear connected to a generator through a train of gearing whereby unidirectional rotation is transmitted to the generator when the buoyant body is rocked. In one form, Figs. 2 and 3, a buoy 1 is surmounted by a dome 2 containing a bevel wheel 14 journaled in bearings 9 carried by a plate 3. To the bevel wheel is secured an arm 11 carrying a heavy pendulum weight 13. A shaft 18 carried in bearings 19 has a pair of bevel wheels 20 meshing with the wheel 14. The wheels 20 are connected to the shaft 18 by free-wheel clutches of the ratchet-and-pawl or ball type and the generator is chain driven from a pulley 21 on the shalt. As the buoy is rocked by the waves, the pendulum swings in a vertical plane, and the oscillations of the wheel 14 are converted by the free-wheel clutches into rotational movement of the shaft 18. A rudder or fin 36 is provided so that the buoy may rock in one plane. The current may be employed for lighting a lamp 6 housed in a glass cover 5, and in addition a bell or other sound annunciator may be provided. In a modification, Figs. 9 and 10, a rotatable main shaft 75 carries a bevel wheel 76 to which is secured a curved arm 84 weighted at 85. A transverse shaft 78 journaled in a central bearing 79 carries at one end a bevel wheel 80 meshing with the wheel 76 and at the other end a pinion 81 meshing with a pinion 82 on the shaft of the generator 83. In this modification, the weighted arm performs a continuous circular movement. The invention may be applied to ships, for example to lightships. Fig. 7 shows an arrangement by means of which the current generated in a number of buoys 53 is transmitted to the shore. The conductors 57 from the buoys are led over pulleys 56 on a yard-arm 55 to the mast 54 of a ship and weights 58 are provided for taking up the slack. Conductors 60 transmit the current to the shore. In a modification dispensing with a ship, the conductors from the buoys are secured in a similar manner to a post on the shore.

Filed: 1927-06-21
Abstract: 295,794. Tisdale, J. R. June 21, 1927. Roller and sheet recording- apparatus; temporary recorders.- Records of speed, time of running and the occurrence and duration of events such as lights-on and hornsounding are made upon a strip 12 driven by the vehicle through a shaft 4 and the shaft 7 of the odometer 5. The strip is divided into columns, 13 - - 16 allotted respectively to a speed stylus 26, horn stylus 35, light stylus 36 and a clock-positioned stylus 45. The speed stylus is carried by a bar 24 moved longitudinally by a lever connection 22 with the speed sensitive device 18 and serving also to actuatean indicating drum 29. The horn and lights circuits include electromagnets 32, 33 the armatures of which carry the markers. The time stylus 45 is supported by a spring-controlled lever 41 engaging a 12-hour cam 40 and is normally out of contact with the record-strip. When the vehicle is in motion, however, the consequent displacement of the lever 22 closes circuit at 49 for a magnet 48 the armature of which thereupon depresses the stylus to record time. The record-strip may be of celluloid and in the fom of a continuous band 12, Fig. 2, overlying another band black in colour and coated with wax to provide a temporary record subsequently obliterated when the bands separate in passing around their supporting rollers 9, 10. In another arrangement the record-strip of paper is wound from a supply roll to a clutch-driven receiving roll and a second record-strip underlying the first may serve as a carbon copy.
