Title: Improvements in the control of change speed gear for use with electric motors
IPC: B60L15/20
Filed: 1924-03-17
Abstract: 225,164. Traction Electrique Rationnelle. Nov. 19, 1923, [Convention date]. Controlling variable-speed gearing for use with electric traction motors by electromagnets which are controlled automatically by variations in the driving torque. The torque is transmitted through a flexible coupling, or through epicyclic gearing, or is alternatively taken up by reaction on a swinging field-frame of the driving motor. Electric controllers for the motor circuits may be operated by the same means as the changespeed gear. Fig. 6 shows one form of apparatus in which a motor 2 drives a shaft 3 through an electromagnetic change-speed gear-box 4 and a worm 24 adapted to compress a spring 27 in proportion to the torque. The movement thus produced acts in an electric switch device 10 whereby electromagnets are selectively operated to effect changes in the gear-box 4. Fig. 7 shows an apparatus in which the same object is attained by providing the driving motor 2 with a swinging field-frame which compresses a spring 33 and acts upon an electric switch device 10. If electric control of the motor circuits is required in addition, suitable rheostat contacts 39, Fig. 8, are added to the switch 10 and are connected to the field or armature windings of the motor. The change-speed and control element may have a spring-connection to a manual lever so as to be semi-automatic in character. In a further modification, semi-automatic con trol is obtained by combining manually operated switch with separate torque-operated switches. Several gear-boxes and motors may be controlled by one aperture.

In the device 40 diodes D1 ... D4 receive positive signals from element 28 and every signal charges a capacitor C1 via a resistor R1 and if switch 24 closes while a signal is being received the potential at capacitor C1 turns on a transistor T1 which in turn switches on a transistor T2, the light 38 having been switched on to warn the driver. The positive signal appearing at resistor R6 is transmitted by diode D9 creating at point A a positive potential and a transistor T10 remains conductive so that element 28 continues to deliver control signals as long as capacitor C1 remains charged and an abrupt cut-out of the anti-skid control is prevented.

Abstract: 1,004,010. Thermoelectric devices. SIEMENS-SCHUCKERTWERKE A.G. Feb. 23, 1962 [Feb. 23, 1961], No. 7265/62. Heading H1K. An element for use in thermocouples is formed by extruding semi-conductor material heated slightly below its melting point from a container through an aperture by means of a plunger. Suitable materials are bismuth telluride, germanium telluride, zinc antimonide, and solid solutions of intermetallic compounds the components of which are Ge, Bi and Te; Bi, Te and Se; Bi, Sb and Te; Bi, Sb, Te and Se; Ag, Bi and Se; Ag, Sb and Te; In, As and P, and Ag, Sb, Ge and Te. Prior to extrusion the material, in powdered, sintered or cast form is heated below its melting point, and is mixed with a lubricant such as wax, graphite or carboncontaining paste or low melting lead glass. The die may also consist of a low melting lead glass, or an apertured plate of such glass placed in advance of the die with its aperture aligned with that of the die. Before extrusion the material may also be coated with or inserted in a sleeve of a lubricant such as aluminium, semiconductor or glass to prevent surface cracks forming in the extruded rod. This is subsequently removed. To prevent surface oxidation the material emerging from the die is subjected to a flow of protective gas. Alternatively, the surface of the material is provided with a protective oxide coating before extrusion. In either event the die may have an extension tube to permit cooling of the extruded material before exposure to the atmosphere. A rod with adjacent zones of materials with different thermoelectric properties may be formed by adding these materials successively to the container from which the material is extruded. Specification 907,901 is referred to.

Filed: 1975-02-21
Abstract: 1452254 Impulse generators PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 21 Feb 1975 [26 Feb 1974] 7354/75 Heading H4K A multifrequency pushbutton subscriber's set including a tone generator 1 and a microphone amplifier 2 is provided with circuitry, including first and second networks, 7 and 8, output network 13, 14, 15, 18 and 19, which ensures that during depression of a button, i.e. switchover from the speech condition to the multifrequency signal transmission condition, the D.C. current flowing through the output network remains constant. In this way the transmission to the exchange just prior to a voice frequency "digit" signal of a D.C. pulse which may temporarily block the exchange filter circuits is prevented. A constant current generator 9 supplies whichever of the networks 7, 8 is operative at any given time. With no pushbutton depressed, contacts 24, 25 are as shown, and the speech signals applied at 16 from amplifier 2 are transmitted to the line terminals 5, 6. On depression of a button, contacts 24, 25 are reversed. Resistors 28 and 30 are equal, as are resistors 15 and 19. Hence the D.C. current flowing through the output network is constant, no matter which of the networks 7, 8 is operative. During switchover, the D.C. current in the output network remains constant, because the sum of the D.C. currents flowing in the networks 7, 8 is constant, being equal to the current supplied by source 9. Two transistors (37, 38) in a "long-tailed pair" configuration may be provided between the constant current source and the networks 7, 8, Fig. 2 (not shown). In a further modification the switches 24, 25 are replaced by a single switch (57), Fig. 3 (not shown).
