Title: Improvements in or relating to electric synchronised motors operated through an amplifying electric valve
IPC: H02K29/12
Filed: 1930-02-04
Abstract: 350,506. Motors; television. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats-Unis, Montrouge, Seine, France. Feb. 4, 1930, No. 3820. Convention date, Feb. 25, 1929. [Class 35.] Motors with unwound iron armatures; rotary machines; oscillating machines.-A synchronized motor comprises a stationary and a movable magnet, the motion of which is caused by the variation of the output current of a valve, and the grid of the valve is subjected simultaneously to a synchronizing voltage, which may be provided by a receiver of Hertzian waves, and a periodically varying voltage of different frequency from that of the output current of the amplifier. The movement of the magnet may be rotational or rectilinear. In the form shown in Fig. 1, the rotation of the disc D induces an alternating voltage in the windings B1, B2, connected to the grid of the valve L, which produces a variation of the current in the electromagnet E which sustains the motion and synchronous operation is obtained by means of a voltage supplied by the transformer T. In the form shown in Fig. 2, the voltage which maintains the motion is produced by a source of continuous current and a commutator K on the motor shaft instead of by induction, and this voltage and the synchronizing voltage from the transformer T are applied to the grid of the valve L. By insulating half the circumference of the commutator along half its length, the anode current is suppressed during one half turn but it reaches a perceptible value during the other half, the negative potential of the grid being destroyed. The two-pole electromagnet with the winding B rotates in the fixed field provided by the magnet A, and when it is to be used for television, the perforated disc D is mounted on the motor shaft and has its speed regulated by means such as eddy currents induced in it by a magnet C until a satisfactory position for the image is obtained, at which instant the synchronizing voltage is applied from the transformer secondary by means of the circuit-breaker 11. The perforated disc itself may be used as the motor rotor by providing it with magnetic elements. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement wherein the motor operates non-synchronously ; also it is stated that the motor may be operated by other types of amplifying relays. Where the disc for the reconstruction of an image is used as the motor rotor it is stated that the number of iron insertions should equal the number of holes in the exploring spiral in order to obtain a disc synchronized at each hole. This subject-matter does not appear in the Specification as accepted.

Abstract: 106,291. Conklin, B. March 17, 1916. Fixed-abutment type; movable-abutment type; cooling parts; packing vanes etc.; working-fluid supply. - Relates to rotary internal-combustion engines of the kind having rotary vanes or abutments. In the construction shown in Figs. 1 and 2, five vanes 41 - - 41<4> secured to an outer rotary casing 39 co-operate with four rotary abutments 8 - - 11 carried by a stationary drum 6. Combustion takes place alternately at diametrically opposite points of the drum, and the arrangement is such that the gas mixture is compressed from two diametrically opposite points into a storage chamber within the drum from which it is alternately introduced to the explosion chamber at a point opposite to that at which the gas mixture is being simultaneously introduced into the storage chamber. The gas mixture is drawn by the vanes leaving the abutments 9, 11 into the working chambers 19 through ducts 13, 14, 15, 16 and ports 17, 18 in the stationary drum, which is thereby cooled. A series of ducts, such as 46, 49, are formed in the outer rotary casing so as to register periodically with ports in the stationary drum leading to storage chambers 26, and, by means of these duets, charges of gas mixture are compressed into the storage chambers by the vanes approaching the abutments 8, 10, and transferred to the other side of these abutments for ignition behind the same vanes, the exhaust being discharged by the following vanes, as they approach the abutments 9, 11, through ducts 21, 22, 20, which are always open. Each vane has a spring-pressed packing-piece 42, Fig. 7, and is cooled by air caught by lips 56 on the rotating casing and conveyed through ducts 55<1>, 54<1>. The drum is cooled by the gas mixture as described above and by air forced through apertures 52 by ribs 53 on the rotary casing.

Title: Improvements in or relating to automatic or semi automatic telephone systems
IPC: H04Q3/00
Filed: 1924-02-15
Abstract: 233,793. Automatic Telephone Manufacturing Co., Ltd., and Gillings, C. Feb. 15, 1924. Automatic and semi-automatic exchange systems.-Relates to the extension of calls to and from a manual private branch exchange having more than 10 lines to the main exchange. Fig. 1 shows an arrangement in which there are not more than 20 lines accessible over special third selectors F having two sets of wipers, as described for example in Specifications 170,385 and 186,037, a repeater R being associated with each line to control ringing or signalling of the P.B.X. and supervision and to supply feed current. Night service lines X<2> which are connected through at the P.B.X. are wired up so as to be first choice in the selectors F, and are also accessible through the ordinary connectors in response to particular numbers, as indicated at Z. The repeaters R are wired over lines X<1> to line switches to serve for calls originating in the P.B.X., and additional lines Y are provided for traffic from the P.B.X. only. Fig. 3 shows an arrangement for dealing with a greater number of lines in which the terminals of the' level of the second selector E<1> corresponding to the P.B.X. are connected to 25-point hunting switches HLS, the first five terminals of which are multipled to serve as night service lines, thus providing for 205 lines in all, and each line has an associated repeater R1. In a modification, the night service lines are directly connected to the first few terminals of the selector level, so that hunting switches of the no-normal type may be employed. If the P.B.X. is designated by a number of four digits, means are provided for absorbing one or two digits. Repeater circuits. When the repeater shown in Fig. 5 is taken in use, the line and release relays 4, 9 energize and a circuit through the backbridge relay 8 is completed for a polarized relay at the P.B.X. to light a calling lamp. When the P.B.X. operator plugs in, the polarized relay is shunted and relav 8 operates to reverse the current back over the calling line. A call from the P.B.X. is routed to the associated line switch over wires 13, 14 and the switches are controlled by the operator's dial. In the repeater shown in Fig. 7, the line relay 34 energizes the ringing relay 48 which connects ringing current to the P.B.X. line over the ring cut-off relay 53, and the back-bridge relay 44 operates upon release of the ringing relay. In the case of a call from the P.B.X., the repeater is guarded by the energization of the release relay 37 over test wire 41.

Abstract: 1318499 Selective signalling INTERNATIONAL BUSINESS MACHINES CORP 28 Jan 1972 [3 March 1971] 4051/72 Heading H4 K1H3B1 A receiver for decoding multifrequency signals of which each component frequency is taken from a different predetermined group of frequencies has a different channel for each group of frequencies, each channel including a majority circuit arranged to generate a binary signal representative of the amplitude of a majority of a predetermined number of samples of the frequency signal in the channel, and means for determining the rate of zero crossings of a sequence of the binary signals to determine the frequency of the signal in the channel. The input is passed via an A/D converter to a digital transversal filter which is time-multiplexed with the factors required to obtaining the different groups of frequencies. The filter output goes to the channels mentioned. Each channel consists of a majority circuit followed by a frequency detector. The majority circuit consists of a peak clipper, a sampler and a shift register in series, the shift register stages being connected in parallel to a summer the output of which is compared with a reference value to obtain the binary signal. The majority circuit thus eliminates noise. The frequency detector counts clock pulses for 16 periods of the binary signal (which is a square wave), the count being decoded to identify the component frequency. The decoder output from the channels are combined in a final decoder. Confirmation logic responsive to the channel decoders checks the presence of component frequencies according to simultaneous presence or order of appearance criteria, as appropriate.
