Title: Static excitation system for an alternating current generator
IPC: H02P9/10
Filed: 1960-06-08
Abstract: 887,136. Alternators; automatic voltage-control systems. SIEGLER CORPORATION. June 8, 1960 [June 12, 1959], No. 20112/60. Classes 35 and 38 (4). An exciter system for an alternator is regulated to prevent excessive excitation in the event of a fault. Generator 10 has a field winding 11 excited by an exciter system comprising a current section 18, supplying most of the excitation, and a voltage section 19 sufficient to provide no-load excitation and on-load regulation under normal conditions. Voltage section 19 comprises voltage transformer 21 with secondary winding 23 connected through rectifier 24 and filter network 25, 26, 27 to transistor 29 with a zener diode 31 in its emitter-base circuit. Components 25, 26, 27 are chosen so that the voltage across resistor 27 is proportional to the average generator phase voltage or to the highest phase voltage if they are unbalanced. If the voltage at contact 30 exceeds a predetermined value, zener diode 31 conducts, causing transistor 29 to conduct, supplying current to the control windings 34 of magnetic amplifiers 35 whose output windings 36 are connected through rectifiers to the control electrodes of controlled silicon rectifiers 40. If the generator voltage increases, the current in control windings 34 increases, reducing the current in the output windings 36 and delaying the instants in each cycle at which rectifiers 40 conduct, thus reducing the excitation. In current section 18 current transformers 47 excite field-windings 11 through rectifier 50. The field-winding is shunted by a controlled silicon rectifier 56 and impedance 55. The secondary winding of a saturable pulse transformer 57 is connected in the emitter-base circuit of rectifier 56 and the transformer is saturated by bias winding 59 energized by a constant voltage source comprising zener diode 63 and resistor 62. Control winding 60 is in the emitter-collector circuit of a transistor 67 arranged to conduct when either (a) the field current, or (b) the voltage of the highest phase of the output exceeds predetermined limits. To sense condition (a) resistor 71 is connected in series with fieldwinding 11 and the voltage drop across it is applied to the emitter-base circuit of transistor 67 through diode 72 so that transistor 67 conducts if this voltage exceeds the forward breakdown voltage of diode 72. To sense condition (b) the voltage across resistor 27 is applied through zener diode 69 to the transistor emitter-base circuit.

Abstract: 1,109,262. Making pastry encased foodstuffs. ASSER ENGINEERING Ltd. 14 May, 1965 [14 May, 1964], No. 20237/64. Heading A2A. [Also in Division B5] A machine for the continuous production of pastry encased foodstuffs (e.g. cakes and pies) comprises conveyer 11, means for laying a base layer of pastry on conveyer 11, means 17 for depositing a filling on the base layer, means for applying a covering layer of pastry on the filling and means 19 for cutting, stamping and shaping the filled foodstuff, means 17 and 19 being mounted in bearings 24 on bars 23 and being reciprocated relative to and in synchronism with the conveyer 11, the filling and shaping being effected and the forward stroke of the reciprocatory motion i.e. when the relative velocity between the means 17 and 19 and conveyer 11 is substantially zero. The reciprocatory motion is imparted to bars 23 by heart cams 22 driven via the main drive to the conveyer 11. The base pastry layer is supplied to conveyer 11 from a reel (not shown) via conveyer 13 and passed below depositor 17. Filling 18 (e.g. currants, sugar and butter) is supplied from hopper 25 via intermittently driven conveyer 26 to hoppers 29 and rings (31) (Fig. 3, not shown) below hoppers 29. The stems 35 are dropped to press the filling in the rings and the hoppers 29 and rings are lifted, leaving the stems 35 to press the filling on the base layer. The stems are raised at the end of the forward stroke of the reciprocatory motion and the hoppers 29 and rings returned to their original position during the return stroke. The stems 35 may have compressed gas forced therethrough to prevent filling adhering thereto. A covering layer is applied to the filling from a reel via conveyer 14. The base layer may be sprayed with water to aid subsequent sealing of the two layers. The composite article is passed to unit 19 where rings 55 which are partially rotated, are dropped to cut the pastry. Near the end of the forward stroke the rings 55 are raised and stems 56 are dropped to compress the pastry product. The components are returned to their original position during the return stroke. Before cutting, the air may be exhausted between the pastry layers by flat press 70, and after cutting the product may be pierced by means 71. The product and trimmings are passed from conveyer 11 to a separating conveyer, after which the product is sugar glazed and baked.

The starting material is prepared by acylating a condensation product of m-cresol and acetone, prepared as described in Specification 273,684, and subjecting the product to depolymerization by the heat treatment process described in Specification 273,686. The formyl and acetyl compounds are particularly suitable as acyl derivatives. According to the examples, the mono-acetyl derivative of the condensation product of m-cresol and acetone, obtained according to Specification 273,684, is heated to about 300‹ C. and the product, comprising a mixture of 3-methyl-6-isopropylenephenol and its acetate. then hydrogenated in the presence of nickel; according to the duration of the treatment, either a mixture of thymol and thymol acetate or of menthol and menthyl acetate is produced, from which thymol and menthol are obtained by saponification. The Specification as open to inspection under Sect. 91 (3) (a) describes the hydrogenation of the acyl derivative of 3-menthol-6-isopropylenephenol alone, and also includes an example according to which the diacetyl compound of 4 : 41-dimethyl- 2 : 2<1>-dioxydiphenyldimethylmethane (see Specification 308,741) yields first a mixture of methylisopropylenephenol acetate and m-cresol acetate and then thymol and menthol by hydrogenation with subsequent saponification.

Abstract: 737,728. Collecting unvapourised fuel. SOLEX. July 24, 1953 [May 12, 1953], No. 20630/53. Class 7(2). An induction system is provided with an outlet 10, controlled by a valve 11 which is open when the engine is stopped and closed when the engine is running, for evacuating both the fuel dripping down the walls of the induction system and the fuel vapour collecting in the induction system. Fuel trickling down the wall of the induction pipe 7 is collected in a groove 6 connected by a pipe 8 to a vapour collecting pipe 18 the end of which is controlled by the valve 11 which is closed by an electromagnet 13 immediately the ignition circuit is closed. The groove 6 has a sloping floor the lowest point of which is connected to the pipe 8 and is arranged immediately beneath the lowest point of the throttle valve when closed so that fuel expelled from the nozzle 3 by vaporization when the engine is stopped is directed by the throttle valve towards the part of the groove 6 adjacent the pipe 8, through which it flows and escapes through the pipe 18 along with any fuel vapour which collects in the lowermost part of the induction system near the entrance to pipe 18. The valve 11 may alternatively be operated by suction operated means or means subjected to the pressure of a fluid pressurised by the operation of the engine, e.g. lubricating oil, cooling water, or fuel.
