Title: Improvements in or relating to phase changing electrical circuit arrangements suitable for use in directional wireless systems
IPC: G01R25/00
Filed: 1938-01-22
Abstract: 509,843. Phase changing valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., FALLOON, S. W. H. W., and MILLING- TON, G. Jan. 22, 1938, No. 2189. [Class 38 (ii)] [Also in Group XL] An adjustable phase shifting arrangement for use, for example, in feeders to or from individual aerial units of a directive aerial system, or between successive stages of a thermionic valve amplifier comprises two mutually perpendicular coils 1, 2 forming parts of oscillatory circuits tuned to different frequencies lying respectively above and below that of the input A.C. applied at terminals 6, 7. Thus currents in quadrature are produced in the coils 1, 2 and induce in a further pair of coils 3, 4 relatively rotatable with respect to the first pair a current the phase of which is dependent upon the angle between the two pairs of coils. The output may be fed through an amplifier comprising a push-pull pair of valves 14, 15 and transformer 20, as shown. The input may be supplied through a single valve amplifier, Fig. 2 (not shown), or it may be applied in push-pull to the grids of a pair of valves the anode circuits of which respectively include the coils 1, 2 in parallel with a seriesconnected combination of resistance and condenser.

Title: Means of connecting pusher boat and barge
IPC: B63B21/56
Filed: 1973-01-16
Abstract: 1386185 Coupling pusher boats and barges TAISEI SEKKEI KOMU KK 16 Jan 1973 [6 March 1972] 2241/73 Heading B7S Shoes 8 carried by a pusher boat 3 are forced by hydraulic units 11 into frictional engagement with vertical channels 5 in the stern of a barge to hold the pusher boat and barge together. The shoes and the pins 7 on which they are mounted can rotate relative to the pusher boat about the axes of the pins. Relative pitching motion can thus occur. The pins 7 move in bearings 6. As illustrated, the forward wall of the channel is deeper than its rear wall. Thus, the pusher boat is positioned by moving it forwards until its shoes contact the forward wall of the channels and then moving the shoes outwards. The walls of the channel may, alternatively, have the same depth, Figs. 1-3 (not shown).

Abstract: 801,548. Phase-sensitive circuits. BENDIX AVIATION CORPORATION. Jan.24, 1956 [Feb. 10, 1955], No. 2358/56. Class. 38 (4). In a demodulator arrangement, Fig. 2, wherein an input signal, Fig. 7, at terminals 20, 21 produces a differential current flow in output or load windings 35, 36 according to the phase of the input signal compared with a reference voltage, Fig. 6, applied at terminals 38, 39, and its magnitude, the currents through the load windings which are equal during alternate halfcycle, Figs. 11, 12, are rendered unequal as in Figs. 14, 15 by the application of the input signal to a transistor 29. Diodes 32, 33 are rendered conductive alternately during alternate half cycles and the current flow in the corresponding load winding is determined by the input signal and bias network 30, 31. An additional bias network and resistor in a modification, Fig. 3 (not shown), form a voltage divider from the collector circuit whereby the transistor is biased to reduce the no-signal current through the ineffective load winding when the current through the other winding is increased. In further modifications. Figs. 4, 5 (not shown), the reference voltage is applied to the two halves of the bridge circuit through two separate transformers, and in the latter Figure the provision of an artificial centre tap allows a two-terminal output to be taken.

Abstract: 849,777. Selective punching-machines. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 23, 1957 [Jan. 26, 1956], No. 2414/57. Class 31(2). A data-punching machine comprises keying means for entering data serially into a first storage means, means operable for transferring the data in parallel from the first storage means to a second storage means, means operable for reading the data serially out of the second storage means to a plurality of punches, and means for feeding a record card past the punches so that the data is punched on the record card. Preferably, each storage means comprises a plurality of selectively-operable relays. As shown, the machine, which is mechanically identical with that described and shown in Specification 684,273, comprises a card feed hopper 100, a punching-station 101, a reading-station 102, a card stacker hopper 103, cardadvancing wheels 107, 108, and rotatable auxiliary and programme drums 109, 110 having reading lines 111, 112, respectively. Each drum 109, 110 has mounted thereon a recordcard containing perforations which are sensed synchronously with the advance of a record card C through the punching station. When the keys of the machine keyboard are operated according to the data to be entered, corresponding electric circuits are completed to selectively energize storage relays. When the data has been keyed into the storage relays, a motor bar is operable to transfer the data collectively to corresponding punch storage relays. The data is read out from the punch storage relays by means of electric circuits controlled by the sensing of the record cards on the auxiliary and programme drums, which circuits bring about the selective operation of punches to punch the data into the record card C. While the data is being read out from the punch storage relays and punched into the record card C and a new record card is being fed into the punching station, the operator may be keying data from the next record card into the key storage relays.

Title: Improvements in or relating to carrier current signalling systems
IPC: H04J1/04
Filed: 1931-01-29
Abstract: 371,885. Wired wireless systems. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.-(Assignees of Green, E. I.; 150, Munn Avenue, East Orange, New Jersey, U.S.A.) Jan. 29, 1931, No. 2891. Convention date, Jan. 30, 1930. [Class 40 (v).] In a carrier-current signalling system wherein a large number of signalling channels are made available preferably by using a transmission line comprising two concentric cables, the carrier frequencies are arranged in groups of channels, and are separated by such small intervals that, in reception, a high-frequency filter having a cut-off characteristic such as A, Fig. 3, is used to select only roughly a given group 1 .. 5. Certain partly suppressed channels, such as 3<1>, 4<1>, 5<1> and 1<11>, 2<11>, 3<11> from adjacent groups will also be passed owing to the sloping sides of the filter characteristic. To remove these, the selected channels are " stepped down on the frequency spectrum by beating with a local heterodyne having a frequency corresponding to the points fa, fd, or the half-way point fb. If the beating frequency is located at fb, the resulting frequency of the channel 1 will be within (fd-fb) of zero frequency, whereas if the heterodyne frequency is located at fa, the resulting frequency of the channel 1 will be (fd-fa) above zero. In each case, low-frequency filters of relatively sharp " cut-off " can then be used to separate the individual speech channels and to eliminate the marginal or unwanted components originally passed by the high-frequency filter A. When the heterodyne frequency is at fb, the arrangement permits of such close spacing between each group that some 245 separate channels can be made in a transmission line having a total frequency range of 1000 kilocycles. The terminal arrangements are shown in Fig. 4. Voice currents from the line TL pass into a channel modulator CM supplied with a carrier frequency from a source CO. One or both side-bands are passed through a band filter BF, and combined with similar channel bands BF1, BF2, &c. of the group. The combined output is then applied to a group modulator GM, supplied with a carrier frequency from a source GO, which steps up the group of channels in the frequency spectrum. The new frequencies are then passed through a group filter GF, and together with the groups from the filters GF1 &c. are applied to the transmission line CXL. The terminal arrangements at the receiving end of the line are shown at the righthand side of the Figure. One of the incoming groups is selected by group filter GF1 and applied to group demodulator GD1 supplied with a beating frequency from source GO1. After demodulation a particular channel is selected by band filter BF1 and the final signal band by a channel demodulator CD1, which may be supplied with a homodyne frequency from a source CO1, before passing through a low-pass filter LPF1.
