Title: Improvements in gramophones and the like
Filed: 1928-04-04
Abstract: 314,602. Beatty, W. E., (Bell Telephone Laboratories, Inc.). April 4, 1928. Systems for transmitting music &c.-A gramophone constructed with two turntables and two electric pick-ups is provided with means for controlling the volume of the reproduction from each pick-up whereby on completion of a record on one turntable the output can be faded out and reproduction from a record on the other turntable brought in by the switching arrangement described in Specification 288,142. The pick-ups deliver through amplifying devices to a loud speaker, and a monitoning telephone or speaker may be provided in the output circuit of either pick-up or in the common output circuit. Fig. 4 shows one arrangement diagrammatically. The turntables 1, 2 are arranged at opposite ends of a cabinet, a control switch being arranged between them. The output circuits of the respective pick-ups 24, 25 are bridged by a retard coil 26, 27 and a condenser and deliver to opposite ends of a series of resistances 41 connected with contact studs 42 of a switch whose movable arm carries insulated metal contacts 45, 46 and is turned through gearing from a spindle 44 and handle 43. The switch contacts connect the studs 42 with segments 47, 48 connected to the amplifying output circuit delivering to a loud speaker 53, and a monitoning loud speaker 55 may be switched into the circuit as desired. Assuming the pick-up 25 operative and approaching the end of the record, the turntable 2 is started by switch 12 and the switch 43 is rotated to increase the resistance 41 in the circuit of pick-up 25 and decrease that in the circuit of pick-up 24 so that the effect of pick-up 25 is gradually faded out, as the other comes in. A switch 49 is provided and when closed the pick-up 25 is cut out wholly when the switch 43 is .moved to mid position. Plug-in switches 37 provide for listening to the two pick-ups separately. Specifications 298,249 and 298,277, [both in Class 40 (ii), Phonographs &c.], are referred to-.

Title: Improvements in and relating to directional wireless receiving systems
IPC: H01Q3/24
Filed: 1937-04-12
Abstract: 492,455. Wireless signalling. REDIFFUSION, Ltd., and GROVE, S. H. April 12, 1937, No. 10367. [Class 40 (v)] The signals from two or more spaced aerials are combined in such phase through variable lengths of connecting cable, and in such amplitude through variable-mu amplifiers, as to produce a polar diagram giving a negligible response to signals arriving from a particular direction. The aerials 10, 11 are spaced apart say by 400 metres and the input may be conveyed through transformers 18, 19 for diversity reception in known manner. But in the lower position of the switches 16, 17, the input feed-lines 14, 15 are connected through reversing switches 20, 21 to jacks 22, 23 and then through jacks 26, 27 leading to a phasechanging unit B in which various lengths of twin cable (marked 100, 50, 20, &c.) are brought into circuit by the switches 28 ... 36. The resulting currents are then passed through jacks 24, 25 to a pair of variable-mu amplifiers 36, 37 through screened input transformers 42, 43. The output is fed to a common load circuit through a choke 48 and condenser 49. In operation the receiver is first tuned to the unwanted station, first on one aerial and then on the other, and the gain of the valves 36, 37 is adjusted to give minimum response, this being reduced to zero by means of the phasechanger unit B. Interference by that station with other desired signals is thus eliminated.

Title: Improvements relating to emergency flotation equipment for aircraft
IPC: B64C35/00
Filed: 1931-05-27
Abstract: 383,964. Fire-extinguishing; storing gases under pressure ; aeronautics. KIDDE & CO., Inc., W., 140, Cedar Street, New York, U.S.A.-(Assignees of Mapes, D. ; Mamaroneck, New York, U.S.A.) May 27, 1931, No. 10605/32. Convention date, June 12, 1930. Divided on 379,348. [Class 47 (ii).] A container for fluid under pressure, adapted for inflating the bags of emergency flotation equipment for aircraft, is provided with means for releasing the fluid intentionally for discharge to the bags through a pipe line, means for releasing the fluid in the event of excessive pressure arising within the container, and means for preventing entry of the fluid into the pipe line when released due to excessive pressure. As shown, the container 6 is sealed by a frangible disc 151 adapted to be ruptured by a tubular cutter 22. The latter has a spindle 23 threaded in a coupling head 16 and operable by a stem 26, pulley 28, and cable 30. The stem is rendered gastight by a shoulder 27 and nut 20. The head 16 is associated with a casing 35 in which is slidable a piston 38 normally raised by a spring 46. The piston carries, at its upper end, a ball socket 43 in engagement with a cam surface 49 on the pulley. When the latter is rotated, to drive down the cutter and release the fluid, the cam surface drives down the piston 38, opening communication between the discharge port 34 and the discharge pipe line 50, If the disc 151 is ruptured by excessive pressure within the container, the piston prevents the passage of the released fluid to the pipe line 50, the fluid escaping through the casing 35 by passages 41, 42. Fig. 2 shows the flotation equipment. The bags are enclosed in envelopes 1, the cover flaps of which are held closed by wires 2 engaging ringlets 3. The wires are connected to a piston within a casing 12. When the pilot opens the fluid container 6 by means of a cable 9, the released fluid first moves the piston to disengage the wires 2 from the ringlets 3, and then passes into the bags through a pipe 5. Specification 379,348 is referred to. The Specification as open to inspection under Sect. 91 states that the fluid containers may be used for fire-extinguishing and other purposes. This subject-matter does not appear in the Specification as accepted.

Title: Digital counter controlled pacer
IPC: A61N1/365
Filed: 1970-03-06
Abstract: 1,267,493. Cardiac pacers. CORDIS CORP. 6 March, 1970 [10 March, 1969], No. 10762/ 70. Heading A5R. A cardiac pacer comprises an oscillator 1 which provides a pulsating signal, a nine-stage cyclically operated digital counter 3 which counts the pulsations of the oscillator and means for generating a cardiac stimulating potential when said counter reaches a predetermined count. The stimulating potential is terminated on the subsequent count. The pacer may be used in demand mode operation, when atrial potentials are not generated regularly, or in synchronous mode operation, when atrial signals are not transferred to the ventriclecommonly called A-V block. In demand mode operation the output electrode 6 and its corresponding flip flap 16 are used. Electrode terminals 6 and 10 may be connected to the same lead. When no ventricular signals are detected the input at D of the flip-flop 16 is high, and the oscillator runs indefinitely in cyclic mode so that when the count changes from 511 to zero the C9 output signal experiences a positive-going transition which is transferred to input C, thus allowing the transfer of the signal at D to Q. This signal is passed through an amplifier 21 to electrode 6 and applied to the ventricle. Between counts zero and 255 the output signal at C9 is low, i.e. input at D of flip-flop 17 is low and therefor, even if a cardiac signal is detected by input electrode 10 and passed to input C, there is no transfer of signal in flip-flop 17 and consequently the counter is not reset. This period stimulates the refractory delay of the heart. Between counts 256 and 511 the C9 output signal is high and consequently a cardiac signal causes the counter to be reset. Simultaneously the output signal from Q of flip-flop 17 goes low, i.e. input at D of flipflop 16 is low, and therefor even though C9 experiences a positive-going transition there is no output signal at Q of the flip-flop 16. In synchronous mode operation output electrode 9 and its corresponding flip-flop 18 are used. Outputs C8 and C9 of the counter 3 are combined to give a high signal only between counts zero and 127, this signal is connected to input D of flip-flop 18. Output C7, connected to input C, experiences positive-going transitions on counts 64, 192, 320 and 448, but only the transition on count 64 will cause a transfer of signal since this is the only transition that occurs when the input signal at D is high. Accordingly a cardiac stimulating potential is generated and applied to the atrium from electrode terminal 9 on each count of 64 and terminated on the subsequent count of 65. The pacer may incorporate circuitry, Fig. 2, not shown, including a two-stage counter, for detecting electronic noise in the environment and preventing the pacer from operating undesirably in response to the noise.
