Title: Improved process for engraving engine-turned metal surfaces
IPC: B44C1/22
Filed: 1935-01-14
Abstract: 447,433. Engraving. WINCOTT, T. E., 122, Wardour Street, London. Jan. 14, 1935, No. 1246. [Class 100 (ii)] A process for engraving engine-turned metal surfaces consists in cutting the incised parts of the design to be engraved to the form of a double channel having a ridged centre 3, by cutting two adjacent parallel or substantially parallel grooves 1, 2 at an angle to the engine-turned surface. The ends of each ridge 3 are cut off as at 4 to form an inclined face in the end thereof, thus giving additional sharpness to the design. The design to be engraved may be transferred to the engine-turned surface from an inked engraved surface, and the engineturned surface may be prepared therefor by coating the surface with pigment to give a white flat surface. The design is engraved by the usual square hand engraving-tool which is ground to a more acute angle than is customary and is highly polished to give a polished cut.

Title: Improvements in temperature responsive electric control switch mechanism
IPC: G05D23/275
Filed: 1948-01-15
Abstract: 645,154. Thermal switches. PLESSEY CO., Ltd. Jan. 15, 1948, No. 1291. Convention date, Feb. 25, 1947. [Class 38(v)] An electrical appliance, such as a range heating element, is periodically energized by a thermal switch, the proportion of each cycle during which the appliance is energized being finely adjustable. A sealed chamber 11 has a diaphragm 12 acting through an adjustable cam 20 on two sets of contacts 63, 64, 65 and 91, 96, respectively controlling a heater 15 in the chamber 11 and the appliance 73, Fig. 7. When the heater 15 is energized, air in chamber 11 expands and causes the diaphragm 12 to move outwardly so as to move the cam 20 axially to move a U-spring 66 overcentre to change contact 63 from contact 64 over to contact 65, thereby cutting out the heater 15. When the chamber 11 cools, contacts 63, 64 reclose and the cycle is repeated. The cam operates contact 63 through an adjustable screw 59 engaging normally a portion 80 of the cam. If the cam is rotated out of its normal range, a portion 81 thereof engages screw 59 and opens contacts 63, 64, regardless of the position of diaphragm 12. The cam also has an inner inclined portion 93 which is engaged by the lower end of an adjustable screw 92. The distance between contacts 91, 96 is adjustable by rotating the cam 20, so as to vary the proportion of the cycle during which the appliance is energized. The movement of the diaphragm 12 therefore produces a corresponding movement of contact 91 which is raised to engage contact 96 which is resiliently mounted so as thereafter to move with contact 91, its downward movement being limited by a stop (not shown). In Fig. 7, the appliance 73 is in series with heater 15, but in a modification, Fig. 8 (not shown), it may be completely independent of the heater circuit. The cam 20 is adjustable by means of a shaft 31, there being a lost motion connection between part 22 of the cam, and the shaft, so as to permit the axial movement of the cam. The shaft 31 also controls a normally-closed main switch (not shown) which is opened at one end of the normal range of movement of the shaft. The upper and lower operating temperatures of switch 63, 64, 65 are both above ambient temperature, so that the switch is substantially unaffected thereby. Specification 628,304 is referred to.

Title: Improvements in or relating to apparatus for electrically determining a function of a plurality of quantities on which a computation is to be carried out
IPC: G06G7/16
Filed: 1944-01-26
Abstract: 597,568. Electrical calculating-apparatus. SPERRY GYROSCOPE CO., Inc. Jan. 26, 1944, No. 1513. Convention date, Jan. 28, 1943. [Class 106 (i)] [Also in Group XL] Apparatus for electrically. determining a function of two quantities comprises a variable gain amplifier, means for varying the input to the amplifier according to the magnitude of one of said quantities, and means for varying the gain of the amplifier in accordance with a function of the other of said quantities. Fig. 2 shows the circuit for multiplication. A constant voltage alternating current E1 with a frequency f 1 is applied to a terminal 29 and an A.C. voltage E2 proportional to the first variable and having a frequency f 2 widely different from f1 is applied to another terminal 28. The two voltages are thus applied to the control grid 19 of a pentode 16, the output of which feeds two band-pass filters 13, 14 passing currents of frequency f1, f2 respectively. An amplitude comparator 12 comprises two full-wave rectifier circuits 36, 37 receiving respectively the output of the filter 13 and an input A.C. voltage E3 proportional to the second variable and having a frequency which may be equal to f 2. The outputs of the circuits 36, 37 are applied in opposition to a D.C. amplifier 38, the output of which is applied to the control grid 19 to vary the gain of the pentode 16 until the voltage supplied by the filter 13 substantially balances the voltage E3, when the output of the amplifier 38 is such that the gain of the pentode 16 is proportional to the voltage E3. The output of the filter 14 passes to an amplitude responsive device 15 such as a voltmeter, oscilloscope or recording instrument. By making E3 equal to E2, the square of E2 may be obtained. The output of the apparatus may be used as the input of a similar apparatus, whereby computations involving several functions may be performed.
