Abstract: 359,928. Moulding tiles &c. by rolling-machines. ABRAHAM, Ltd., R. and ABRAHAM, R. A., Hawes, Yorkshire. July 23, 1930, No. 22160. [Class 87 (ii).] Apparatus for strickling concrete in moulds, which is applicable specially to the apparatus described in Specification 313,295, [Class 87 (ii), Moulding plastic &c. substances], for making concrete tiles, comprises a vertical or inclined driven belt which moves the heaped-up concrete rearwardly as the mould passes under it. Fig. 5 shows one construction of apparatus in which the mould A, comprising a wooden frame with loose base and asbestos sheet as described in the former Specification, is loaded with a heap of material at its forward end and then pushed under the roller C carrying a driven belt P. The material contacts with the downward run of the belt and is strickled thereby, finally passing under the roller C. The charging may be made automatic by causing the mould to open the outlet door of the storage hopper when it reaches a certain point. Various arrangements of belts for the strickling operation are described, with means for reversing the drive so that the moulds can be fed thereto from either end of the apparatus. The strickled mould is moved laterally into position II where it is treated by a roller apparatus R<1> as in the prior Specification and finally is moved to position III where the mould is removed and returned by a conveyer to the loading point. Two machines may be arranged side by side so that the mould when stripped from the tile after use in one machine is in position for receiving a fresh charge in the other machine.

Abstract: 480,090. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.) Aug. 18, 1937, No. 22688. [Class 38 (iv)] [Also in Group XXXVII] Electromotive force.-The voltage of an A.C. feeder 3 is automatically regulated by injecting an e.m.f. in series therewith by means of autotransformer 2, the tapping of which is varied by a reversible capacitor motor 1 responsive to the voltage of the feeder. A contact making voltmeter 4 closes contacts 5, 6, respectively when the voltage varies a predetermined amount below or above normal. Thus when the feeder voltage is high contact 6 closes to energize a relay 8 which energizes the motor over contacts 12, 13 and over contacts 14 energizes an auxiliary relay 10 which in turn energizes a time delay drop-out relay 11 over a rectifier bridge 9. The motor adjusts the regulator 2 until the voltmeter contact 6 opens, when relay 8 de-energizes to disconnect the motor from the A.C. supply, and de-energize relays 10, 11. Contacts 18 of the relay 11 remain closed, however, during the delay period thereof, during which the motor stator is supplied with D.C. for dynamic braking over contacts 18 of relay 11 and contacts 19, 20 of relay 10 from the rectifier, the time delay being adjusted so that the relay drops out just as the motor has been braked to rest. In a similar manner, voltmeter contact 5 operates a relay 7 to adjust the regulator 2 in the opposite sense.
