Abstract: 359,202. Stereotype. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Wood Newspaper Machinery Corporation; 501, 5th Avenue, New York, U.S.A.) Oct. 18, 1930, No. 31316. [Class 100 (ii).] In a stereotype casting-machine of the type in which the core 11 is rotatably mounted on a horizontal axis and the back 12 is vertically reciprocable to and from the core, the back is also adapted to swing about an axis situated at a distance from its convex side to facilitate access to the matrix. The back 12 is connected by rods 14 to cranks on a shaft 13, the back and rods 14 being connected together by eccentric pins 15 actuated by arms 16 and adjusting-screws 17 for effecting correct engagement of the back and core. The back is normally held in position beneath the core by springs 22 and adjustable stops 23. The back is guided by extensions 21 which slide over guides 20 pivoted on the concentric part of the shaft 13 and connected by turn-buckles 24 to arms 25 on a shaft 26 oscillated by a handle 27. In use, the back normally reciprocates under the influence of the crank-shaft 13, towards and from the core for casting and removal of the plate. When the mould is closed, the matrix holders engage with studs 29 fixed to the frame in order to force the matrix into position. In order to insert a new matrix the back is withdrawn from the core and the shaft 26 is rotated by the handle 27 to swing the back and guides 20 away from the core. The turn-buckle 24 and arm 25 form a toggle in both the vertical and inclined positions of the back.

Title: Improvements in or relating to the reproduction of magnetic records of sounds
IPC: G11B5/00
Filed: 1948-12-08
Abstract: 658,796. Magnetic sound - reproducing. PERREAU, H. Dec. 8, 1948, No. 31796. Convention date, Dec. 11, 1947. [Class 40 (ii)] When magnetic recording, in a magnetic band or wire, has been made at constant magnetic intensity and not at constant voltage, a correction is necessary when reproducing the record to counteract the effect of rising E.M.F. with rising frequency. According to the invention such a correction is provided by a correcting circuit which is connected in parallel with the translator head winding L, r connected to the terminals A, B of the input transformer, the correcting winding having such resistance, selfinductance and capacity (or some of these properties) that, though its impedance is small compared with the input impedance of the amplifier, it remains substantially constant at all frequencies up to a critical frequency at which losses result in a dropping of the characteristic response curve and increases with frequencies beyond that point. It is shown in the Specification that, if R and r may be neglected in comparison with Lw (w=2# x frequency), the voltage across AB is substantially constant for frequencies up to those at which the induced E.M.F. ceases to rise on account of losses. To compensate for frequencies above this value an additional self-inductance may be connected in series with the resistance R across the terminals AB. In a modification, Fig. 4, a circuit tuned to the highest frequency which it is desired to reproduce may be introduced, and this may have a potentiometer P by the adjustment of which a linear curve of response may be obtained.

Title: Telegraph switching system
IPC: H04L12/54
Filed: 1961-09-08
Abstract: 940,191. Telegraphy. STANDARD TELEPHONES & CABLES Ltd. Sept. 8, 1961 [Sept. 12, 1960], No. 32371/61. Drawings to Specification. Heading H4P. In a telegraph switching centre comprising one or more incoming lines and a number of outgoing lines, each line has associated with it a store and a transmitting means, and also means for transmitting on an established crossoffice connection a parity check signal with each character code combination. This parity signal is compared at the outgoing line store with a derived parity signal. In the embodiment described incoming signals are in 5-unit code and each message includes routing signals and " start of message " and " end of message" signals. Associated with each line is a tape perforator and tape transmitter. After the incoming signals are stored at the receiving units a director sets up cross-office connections between the incoming stores and the outgoing stores at the sending units that serve the addresses specified by the routing signals. If the sending units requested are idle an allotter operates to ensure that only one cross-office connection is made at any time, and also prevents more than one receiving unit from being connected to the same sending position at any time. A parity bit is derived at the receiver unit and is transmitted crossoffice with the message signals. This parity bit is stored and as the tape store at the sending unit is read out a corresponding parity bit is derived and compared with that transmitted. If a message has a multiple address, i.e. is to be transmitted over more than one outgoing line, it is routed to a multiple address unit and when the paths from the incoming tape reader to the outgoing tape perforators are set up the message is transmitted over all these paths simultaneously. However, if a parity check at any outgoing tape reader indicates an error, the signals on that tape are not sent to line. Signals from the other tapes are not inhibited. In the event that a multiple address message is passed through several switching centres, a switching centre ignores the routing signals indicating addresses served by a centre through which the message has already passed.
