Patent GB-956460-A (GB)
Title: Production of thiocarbamates and thiocarbazates
IPC: C07C333/02
Filed: 1960-07-13
Abstract: A salt of a thiocarbamate or thiocarbazate is prepared by absorbing carbonyl sulphide into an admixture of (a) a primary or secondary mono-or polyamine, or a hydrazine disubstituted on one nitrogen atom, and (b) an aqueous alkaline medium, the amount of carbonyl sulphide used not exceeding a 10% molar excess with respect to the compound under (a) and the amount of alkali present being at least sufficient to neutralize the thiocarbamate or thiocarbazate.  The process may be modified to produce an aliphatic ester of an N-substituted thiocarbamate by the inclusion of an aliphatic halide in the reaction mixture, preferably by introducing the carbonyl sulphide and aliphatic halide concurrently into the reaction mixture.  The mole ratio of carbonyl sulphide to amine or hydrazine is preferably one or less.  General suitable inorganic and organic bases are specified. Many suitable aliphatic halides and suitable amines and hydrazines are specified, the amines including cyclic amines and amines having as substituents halogen atoms or cyano or etherified hydroxy groups. Examples are given. In Example 5, allyl n-amylthiocarbamate is obtained by treatment of ammonium n-amylthiocarbamate with allyl chloride.  The Specification disclaims the processes specifically as described in Specifications 882,110 and 882,111.

Title: Die forming apparatus
IPC: B21D37/02
Filed: 1974-06-03
Abstract: 1424979 Bending metal CATERPILLAR TRACTOR CO 3 June 1974 [13 July 1973] 24449/74 Heading B3E A workpiece is formed progressively from one end to the other between opposed dies one 28 of which presents a corrugated face, Fig. 4, while the other consists of a plurality of members 42, 44, 43 successively forced into engagement with the workpiece by a wedge member 57. The members 42, 44, 43, have bevelled upper ends 49 and are loosely supported on rods 51 mounted in frames 36 which depend from an upper platen 24 so as to leave a way for advance of the wedge member 57. The lower die is mounted on a lower platen 22, Fig. 1, the upper platen being mounted on the rod 18 of a ram 17 and sliding on guides 23. A ram 62 mounted on the upper platen reciprocates the wedge member 57 and is connected in the same hydraulic circuit as ram 17. A spacer block 26 adjustable by shims 27 is located between the platens. When pressure fluid is admitted to conduit 74, the ram extends readily, producing lower pressure in the conduit, until platen 24 abuts spacer 26, the die members then being in light contact with the workpiece. The pressure then builds up in conduit 74, which operates a sequencing valve 82 to admit pressure to conduit 78, operating ram 62 to effect the corrugation progressively. When pressure fluid is admitted to conduit 76, it first retracts ram 62 at low pressure, and then causes ram 17 to raise platen 24 until a microswitch (not shown) is operated to remove all fluid pressure and set an hydraulic lock on the rams.

Title: Improvements in temperature regulating systems for direct-cooled windings of dynamoelectric machines
IPC: H02K9/24
Filed: 1959-07-16
Abstract: 919,700. Cooling systems for dynamo-electric machines. GENERAL ELECTRIC CO. July 16, 1959 [July 24, 1958], No. 24464/59. Class 64(3). [Also in Group XXIX] A cooling system in which a coolant such as oil or purified water, is circulated, from a reservoir 5, e.g. by a pump 6 through passages formed in the coils 2 of a dynamo-electric machine such as a generator and thereafter cooled in a heatexchanger 12, comprises on the coil inlet side a first temperature-sensitive arrangement 18, 20, 21, a proportioning device such as a valve 10 which controls the amount of fluid passing through the heat-exchanger and a total-flow determining device which may comprise a valve 9 or the pump 6, and on the coil outlet side a second temperature-sensitive arrangement, 15, 16, 17; these temperature-sensitive arrangements being connected to the proportioning device to adjust the temperature of the fluid supplied to the winding. In the form shown, the device 15,16,17 acts to maintaina constant coil outflow of the coolant by regulating through the valve 9 the rate of flow of coolant. A throttled by-pass 7a is provided around the valve 9 to ensure a minimum flow of coolant in the system should the valve 9 be closed. The coolant inlet temperature is maintained constant by the valve 10 through the device 18, 20, 21. In a further form described, the valve 9 is omitted and the total-flow determining device comprises merely the pump 6, which supplies a substantially constant quantity of coolant to the coil inlet (Fig. 3, not shown), the system including a computing type relay which senses the inlet and outlet temperatures of the coolant passing through the coil, averages them, and positions the valve 10 so that a constant average between these temperatures is maintained. In yet a further form described (Fig. 1, not shown), the control mechanism for operating the valve 9 operates jointly in accordance with the load imposed on the generator and the outlet temperature of the coolant to maintain this temperature constant when the generator is operating above a predetermined load condition. When the load drops, the quantity of coolant admitted to the coils is reduced by the valve 9 to raise its temperature to the desired constant value. Below a predetermined loading such as 40% when the heat in the coils is insufficient to maintain the coolant outlet temperature to this value even with the valve 9 closed, a proportional relay element (24; Fig. 1, not shown) modifies the coolant outlet temperature signal received through the temperature-sensitive device 15, 16, 17 such that the valve 10 is then operated to direct less coolant through the heatexchanger hence raising the coolant inlet temperature. The coolant may be warmed up prior to starting the generator by means of a heating coil 5a located in the reservoir 5 or by passing a heating fluid through the heat-exchanger 12. A gaseous fluid coolant may be used.

Abstract: 674,916. Radio receiving and transmitting circuits. GIALLULY, E. M. S. DE. Oct. 6, 1950 [Oct. 28, 1949; Nov. 18, 1949; July 17, 1950], No. 24502/50. Class 40 (v). In a waveband switching arrangement in which a number of ranges are obtained by switching alternative inductances across the tuning condenser CV1, by means of switch contacts 1, 5, 9, &c., a further set of tuning ranges is obtained by switching a fixed condenser X1 in parallel with the condenser CV1. A number of ranges may be obtained by switching a plurality of fixed condensers into circuit; the switching may also be so arranged that different condensers are utilized for differing groups of wavebands. An inductance may be used instead of the condenser X1 and may alternatively be arranged so as to be connected in series with the tuning coils.
Patent GB-1278908-A (GB)
Title: Fuel injection
Inventor: MOULDS JOHN WILLIAM
IPC: F02M63/00
Filed: 1971-04-19
Abstract: 1278908 Spray carburetters GENERAL MOTOR CORP 19 April 1971 [22 May 1970 24517/70 Heading F1B Fuel injection system for an I. C. engine comprises a fuel injection nozzle in a housing defining a valve-controlled fuel discharge passage, means for opening the valve for a controlled period of time and heat responsive means in heat exchange contact with the housing for adjusting the controlled period of time by lengthening it to discharge more fuel when the housing temperature exceeds a predetermined value, thus compensating for the reduction in fuel density due to vapour bubble formation in the nozzle. The injector 10, which discharges into the induction manifold adjacent the inlet valve 16 comprises a body 20 in which is secured a nozzle 24. Fuel passes through a hollow plunger 28 and is discharged through an orifice 44 when the plunger is lifted to move a valve member 42 off its seat in the nozzle. The solenoid 46 is energized to provide a force which acts on the head 34 of the plunger to raise it against a spring 58. The travel of the plunger is limited by the engagement of a flange 62 thereon with a spacer disc 64. The temperature of the injector body and hence of the nozzle 24 is sensed by a thermister 124 the end of which is held in engagement with the body by a spring clamp 122. The circuit which controls the electrical supply to the solenoid consists of a generator 126 which provides a negative voltage pulse at each engine cycle. Capacitor 128 differentiates the pulse into a negative spike which is applied to the base of transistor 132, so that it ceases to conduct. The voltage at collector 13 rises and causes transistor 136 to conduct, so that the voltage at its collector 138 falls and an amplifying transistor 140 ceases to conduct. The voltage at the collector 142 of this transistor then rises, so that the solenoid 46 is energized. As transistor 136 starts conducting, current flows in the primary winding 144 of a transformer which has a core 146 positioned by a transducer responsive to the absolute pressure in the manifold. The changing primary current induces a voltage in secondary winding 150, which biases the base of transistor 132 negatively, so that it remains non-conducting. As the rate of current change in primary 144 drops, the negative secondary voltage drops, transistor 132 conducts and solenoid 46 is de-energized. Thermistor 124, together with resistors 152, 154 and 156 control the primary current flow and since the resistance of the thermistor 124 decreases as the injector body temperature increases, the primary current increases and lengthens the time for which solenoid 46 is energized. Typically, when the fuel is supplied at 40 p. s. i. pressure the thermistor resistance starts to decrease at 140‹F. and the injection time increases linearly so that it is 24% longer at 200‹F. than at 140‹F. The Specification also describes the invention claimed in Specification 1279065.
