Title: Apparatus for indicating the number of kilometres travelled by a motor vehicle per litre of petrol, and the like
IPC: G01F9/00
Filed: 1922-04-20
Abstract: 199,543. Schiske, R. April 20, 1922. Speed indicators with means for measuring consumption of petrol.-An arrangement for use in motor-cars &c. for indicating the fuel consumed per kilometre or the distance travelled per litre of petrol comprises two logarithmic curves on discs or slides which are adjusted respectively by the fuel meter and the speed indicator, the distance between the points of intersection of the curves with a fixed line being read off on a scale. In the apparatus shown, a rotary disc 1 connected with the petrol meter indicates the consumption per hour by means of a circumferential scale and a fixed pointer or line 5. The number of kilometres per hour is similarly indicated bv a transparent disc 3 mounted on the disc 1 and connected to the speed indicator. The logarithms of the scale numbers are marked on the corresponding radii, the measurements being made from the circumference. The two curves 2, 4 are thus formed on the discs, the curves 4 being at the back of the disc 3. The quotient of the readings of the circumferential scales is obtained by reading off the distance a, b between the points of intersection of the curves 2, 4 and the line 5, on an adjustable logarithmic rule 6 sliding between the discs 1. 3. The. rule may be moved automatically bv a pin sliding in a groove. Slides may be substituted for the discs if the petrol meter and speed indicator give rectilinear motions.

Abstract: 1,030,235. Binding posts. WESTERN ELECTRIC CO. Inc. March 21, 1963 [March 26, 1962], No. 11194/63. Heading H2E. A connector comprises at least one terminal member cut from metal stock of flat crosssection. If there is more than one terminal member, these members are joined together by means of an integral base 11, and each terminal has insulation penetrating jaws 13, 14, and is formed by bifurcating the terminal by means of a shearing die, from the free end to the integral base section, the functions being spaced apart adjacent to the base section to form an elongated slot. The edges 13A and 14A of jaws 13 and 14 are in intimate contact with each other at all points when there is no conductor forced between them. One arm has a rounded end 15, and the other arm is longer and has a sideways protrusion 16, extending partially over end 15, to form a conductor receiving passage, and opens into a U-shaped notch bounded by bevelled edges 17 and 18. The connector may be disposed in a support member the upper surface of which is located intermediate the ends of the sheared slit and this prevents conductors from being forced into the elongated slit and losing electrical contact. A connecting device, Fig. 2 (not shown) may be constructed by having a plurality of such connectors arranged in a predetermined geometrical array.

Title: Improvements in railway signalling arrangements
IPC: B61L3/18
Filed: 1946-04-12
Abstract: 635,055. Railway signalling apparatus. SOC. AUXILIAIRE D'ETUDES ELECTRO-TECHNIQUES. April 12, 1946, No. 11363. Convention date, April 13, 1945. [Class 105] Apparatus for giving a warning signal on a train when approaching a danger point such as an ahead train, wrongly set points, or a level crossing, which comprises a wheel-driven electric generator on the train giving an electromotive force proportional to the speed and feeding through a relay a trackside wire so giving a warning signal at a distance varying with the speed by the response of the relay to the increasing current, is provided with an auxiliary source of constant voltage which comes into action when the generator voltage, for example, due to reduction in speed, falls below a certain value. As a clear signal is given by the trackside-wire current falling below an operative value it is necessary to check the integrity of the circuit and this is done by including, in the circuit to the cab signal proper, front contacts of relays included in the circuit containing the trackside wire. If alternating current is to be used the supply is given by a constant-frequency generator the field winding of which is supplied from a wheel-driven direct-current generator. As shown a wheel-driven direct-current generator 3 and an auxiliary source of constant voltage, such as a battery 24, are connected through rectifier units 27, 28 to a wire 29 leading to the shoe which engages the track-side wire. The rectifiers allow the battery to come into action automatically when the generator voltage falls below that of the battery; the rectifiers also prevent battery current flowing to the generator and vice versa. The return line of the track-side circuit (the rails) leads to the current coils of wattmeter type relays 53-103, 55-105, 52-102, 54-104, 51-101. At a danger point such as at a train ahead the trackside wire is bridged to the rails and the increasing current operates the wattmeter relays to open their back contacts so that relays 35, 36, 37, the two latter being stick relays, drop their armatures to cancel the clear cab signal 231 and substitute a warning signal 232, 233 or 234 as the case may be. If the increased current is such as to operate only the first wattmeter relay 51-101 the first warning signal 232 is actuated but this is cancelled at once if the speed is reduced to allow wattmeter relay 51 - 101 to drop and so reenergise relay 35. If however the increased current is such as to operate wattmeter relays 54-104 and 52-102 the relay 36 is dropped and the second warning signal 233 comes into action. This signal is cancelled only when the speed reduction is such as to allow wattmeter relay 54-104 to drop and so pick up relay 36. The final warning signal 234 is similarly controlled by the operation of wattmeter relays 55-105, 53-103 causing relay 37 to be dropped and subsequently picked up on reduction of speed.

In order to limit the torque required to drive an alternator under short circuit conditions, the field excitation of the alternator varying directly with alternator load current, the field current is limited. The main alternator 10, driven by a prime-mover 24 is excited by the rectified output of an alternator 20, which in turn is excited by the rectified combined outputs of potential transformers 74, 76, 78 and current transformers 102, 104, 106 energized by the main alternator 10. A 3-phase self-saturating transductor 60 is connected between the field of the alternator 20 and the transformers. In addition to the load windings 132 and fixed bias windings 182, the transductor 60 has control windings 170 energized from a voltage measuring bridge 50 connected across the output of the main alternator 10 so as to normally maintain the output voltage constant. However, a fourth set of windings 150 are energized to reduce the excitation current when this current is large enough for the voltage drop across a series resistor 27 (or across the field itself, Fig. 2 (not shown)) to break down a Zener diode 88.
