Title: An Improved Process for the Manufacture of Converter Bottoms, Furnace Hearths and the like for Metallurgical Purposes.
Inventor: THOMPSON WILLIAM PHILLIPS
IPC: B28B1/08
Filed: 1916-11-16
Abstract: 108,412. Thompson, W. P., (Bosshard. A.). Nov. 16, 1916. Converters.-In the manufacture of converter bottoms, the mixed materials, such as dolomite and coal tar, are consolidated by shaking, instead of by ramming or stamping.

Title: Improvements relating to automatic telephone systems
IPC: H04M15/10
Filed: 1932-06-10
Abstract: 393,089. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and CHRISTIAN, D. A., Morven, Charlton Road, Charlton, both in London. June 10, 1932, No. 16403. [Class 40 (iv).] In a booster battery metering system the line relay is connected to the holding wire during a conversation and is normally shorted but is energized on the receipt of a booster impulse and completes a circuit for the meter, which includes the holding wire, for the duration of the impulse. A rectifier is connected in the line finder test circuit to prevent locking up of the succeeding switches on the release of a connection and a test jack enables the condition of the circuit to be ascertained and the meter to be tested. When a call is initiated L energizes over SL and ST enables LF to hunt for the calling link LC. K energizes when the link is found and L falls away, its right-hand winding being shorted by the similar potentials at P and k1. When the called party replies, booster battery is connected to P and L reenergizes, disconnecting the final selector private wire and connecting the meter MR to k1 so that the meter is energized by the booster impulse. When the impulse terminates both L and MR are shorted and fall away, L opening the circuit of MR and reconnecting the P wire to the final selector FS. When the conversation has terminated holding earth is disconnected from P and the two windings of K are connected in series, K releasing under this condition. The left-hand winding of K is of low resistance compared with the right-hand winding of L to prevent L re-operating at this time. The rectifier RR prevents earth being fed forward from LC to hold the succeeding switch. train during the release of K and at times when (i) a final selector tests the line at the moment of release and (ii) the line is being cleared for the completion of a trunk call, earth being fed forward from FS over P to re-operate K as soon as the subscriber clears. The test jack MTJ enables-the condition of a line, i.e. busy or free, to be ascertained, battery being found on a free circuit and earth on a busy one ; and allows the meter MR to be tested by the connection of booster battery to the jack with or without a prior application of earth to energize K. The arrangement is particularly suitable for multi-metering systems.
Patent GB-1593484-A (GB)
Title: Feed apparatus for intermittently feeding sheet material
IPC: B65H20/18
Filed: 1978-04-26
Abstract: The printed foil (3) is drawn from a stock roll (4) in steps by a gripper (2) over a table (1). The foil (3) has markings (6) which correspond to the spacing (t) of the printed pattern and which influence a photoelectric sensing head (7). A roller (9) serving as a retraction member for the foil can engage to a greater or lesser depth into a transverse gap (19) of the table (1). The roller (9) is connected via a linkage (13, 14) to an armature plate (42) which is pulled up by an electromagnet (36) when the latter is energised. During each feedstroke, the foil (3) is drawn forwards by the gripper (2) over a length (v) which is greater than the spacing (t). The roller (9) is then actuated and retracts the foil until a marking (6) influences the sensing head (7), the latter energising the electromagnet (36). The movement of the roller (9) is thereby stopped immediately. The feed apparatus allows an accurate feed and works virtually free of wear. <IMAGE>
