Patent GB-793369-A (GB)
Title: Improvements in or relating to electric supply changeover switching apparatus
Inventor: CRAVEN ROYSTON ARTHUR FREDERIC
IPC: H02J9/06
Filed: 1955-01-13
Abstract: 793,369. Stand-by systems. WATFORD ELECTRIC & MANUFACTURING CO., Ltd. Jan. 13, 1956 [Jan. 13, 1955], No. 1123/55. Class 38 (4). Two separate A.C. generators provide respectively a normal supply on lines 20 and an alternative supply on lines 21, a load being connected to lines 22. Contactors CN, CA connect the load to one or other of the supply systems and are provided with interlocking contacts so that the two contactors cannot be energized simultaneously. A three-phase torque motor having windings 11 drives a spring-loaded contact arm 10, whereby, when the normal supply voltage falls, the arm engages contact 10a to short-circuit relay K1. After a period of delay, with the supply voltage continuing to stay at a low value, contacts K1-2 open to release the contactor CN, and contacts K1-3 close to prepare the energizing circuit for the contactor CA. The release of the contactor CN causes its contacts CN-2 to close, thereby short-circuiting the relay K2 so that, after a period of delay, contacts K2-1 close to energize relay SR2. The contacts SR2-1 are thereby closed, thus completing the energizing circuit for the contactor CA. The restoration of the normal voltage supply caused the arm 10 to engage contact 10b and re-energize the relay K1. The opening of contacts K1-5, and the consequent opening of contacts SR2-1, causes the contactor CA to release. The closure of contacts K1-2, K1-4; prepare the energizing circuit for the contactor CN and the relay SRI, respectively. The deenergization of the contactor CA causes contacts CA-2 to short-circuit relay K3 and, after a period of delay, contacts K3-1 close, thereby energizing relay SR1, so closing contacts SR1-1: The contactor CN is thus re-closed and the load is re-connected to the normal supply system. The contactors CN, CA are of shockproof construction and the various relays are of the slugged type, and are so adapted for slow release. Chattering of the contacts K2-1, K3-1, is prevented from affecting the contacts SR2-1, SR1-1, owing to the slow release characteristic of the relays SR2, SR1. In a modification, the self-holding contacts Kl-1, and the contacts K1-5, are replaced by a movable contact of the relay K1 adapted to engage either of two fixed contacts, Fig. 1 (not shown). Either of the contactors CN or CA may be closed manually, in which case the coils 23, 24 are disconnected to prevent automatic operation of the contactors. Capacitors C1, C2, C3 are provided in the leads to the torque motor to compensate for frequency changes in the normal supply, the resulting torque of the motor being an indication of the effective supply-voltage. Resistors R1, R2, R3 enable the terminal voltage of the torque motor to be balanced. Specification 721,747, [Group XXXVII], is referred to.

Title: Improvements relating to temperature responsive devices
IPC: H05B1/02
Filed: 1937-01-16
Abstract: 489,005. Electromagnetic switches electromagnets. COSGRAVE, W. J. G., and ELECTRIC RESISTANCE FURNACE CO., Ltd. Jan. 16, 1937, No. 1393. [Class 38 (v)] [Also in Group XXXV] A temperature-responsive device, which may control the temperature of a furnace by cutting off the heating current when the temperature reaches the desired maximum, comprises a magnetic member 11 which becomes demagnetized with rise of temperature. In the form shown, the tube 11 of a special alloy is adapted to be screwed on to an iron tube 1 which supports within itself a silica sleeve 3 through which passes a magnetizable rod 2. A magnetizing coil 9 surrounds the sleeve 3 and a magnetizable washer 8 helps to complete a magnetic circuit, the poles of which are constituted by a projection 13 and the left-hand end of the rod 2. When a current is passed through the coil 9, the rod 2 is thus attracted to the left and holds a lever 16 carrying a platform 20 and mercury switch 21 in the position shown against the action of a spring 19. The end 11 is located within the furnace, and when demagnetized by heat, allows the spring 19 to tilt the mercury switch 21 controlling the furnace into the open position. In a modification, Fig. 2 (not shown), there is no washer 8 and no spring 19, the rod 2 tending to assume a central symmetrical position within the coil 3 when the end 11 is demagnetized. In another form, an alternating magnetic flux is caused to traverse two coils arranged in opposition, one coil magnetizing a body of special alloy and the other a normally magnetizable body. With rise of temperature, the former body loses its magnetic properties, and the voltage induced in its coil becomes reduced. The voltage of the other coil predominates and a relay is operated.

Title: Improved process of producing yeast
IPC: C12N1/16
Filed: 1927-01-18
Abstract: 294,134. Sak, S. Jan. 18, 1927. Yeast. - In the manufacture of compressed yeast, commercial yeast, seed yeast, or mother yeast, part of the fermenting wort is withdrawn from the vat and centrifuged, and the centrifuged yeast is transferred to another vat containing fermenting wort the concentration of which in respect of nutrients or other substances is higher than that of the first vat; after the yeast in the second vat has displayed a. more or less intense activity of growth, it is returned to the first vat. The yeast may be passed through several vats before being returned to the first one. During the process, the transfer of yeast from one vat to another may be regulated so that for a certain time the concentration of yeast in a vat is maintained constant or is gradually increased or decreased, and this may be done so that the nutrients are practically wholly consumed, or alcohol is present or absent. Yeast from an outside source may also be added. Added yeast may be in the compressed form or otherwise. The centrifuged yeast may be separated from the wort by pressing. Fresh wort or centrifuged wort may be added during the process, and the piocess may be carried on for several days and nights without substantial interruption. During the period when centrifuged wort is added, the withdrawn yeast may be returned without the wort being centriruged therefrom.

Filed: 1941-02-11
Abstract: 546,935. Steering wheels. BIRNIE, J. D., and BIRNIE, D. F. Feb. 11, 1941. No. 1845. [Class 80 (iv)] Steering wheels of the kind provided with a rim core and hub usually of metal connected by spokes, and in which the rim core is covered with a moulded plastic material. are manufactured by moulding the rim in sectional lengths which when assembled form a complete ring, the mouldings of a length being similar in shape so that a set of mouldings can be produced in one set of dies. The invention is particularly applicable to wheels having a metal rim connected by spokes to a metal hub, the rim being coated, e.g. with celluloid. In Fig. 1, three lengths, each consisting of a pair of mouldings, are employed. The half of one pair, Fig. 3, has a rim portion 10 with an external shoulder at 11 and a reduced portion 12 beyond the shoulder. This portion is slotted at 13 to clear the spokes when it is inserted into a recess 17 in an adjacent moulding. At the opposite end the moulding has an integral spoke portion 14 provided with a number of half circular section grooves 15 to receive the spokes. The parts 10, 10A may be of similar or dissimilar shape, and are grooved to fit over the metal rim 18 to which the spokes are welded, and may be provided with finger grips. With two moulds, the six combined rim and spoke portions may be produced. The sections may be united at their ends with cement and, for greater security, the engaging parts may be ribbed and grooved. Instead of the spoke portions 14 being integral with the rim portions, they may be separately formed, each of the rim portions then having a reduced socket portion at each end. With this construction the rim and spoke portions may be in materials of different colour. The spoke portions may extend farther towards the hub and in extreme cases right up to the hub.
