Abstract: 909,681. Electric signalling. BRITISH PETROLEUM CO. Ltd., and PHILLIPS, R. M. July 17, 1959 [July 30, 1958 (3)], Nos. 24598/58, 24599/58 and 24600/58. Class 40 (1). [Also in Group XVIII] The quantity of petrol passing through a selected meter of a plurality of meters is registered on an indicator 33, Fig. 1, actuated in response to electrical signals from a transmitter operated by the selected meter. In Fig. 1, fuel from storage tanks 1, 1A, is fed by pumps 2, 2A to meters 6, 6A, connected to dispensing nozzles 10, 10A, the meters 6, 6A, each operating a pulse transmitting device 15, 15A, connected to pulse counting mechanisms actuating indicators 33, 34, which register respectively the amount and the cost of the petrol dispensed. Removal of a nozzle, e.g. 10, from its stand permits operation of its associated spring- loaded switch bar 18 which first operates a switch bar lock switch 23 to energize solenoids 26A holding all the other switch bars inoperative. On further movement the bar 18 operates a transmitter and counter reset switch 24 and a switch 25 which set the pump 2 and transmitter 15 into operation, whereby the quantity dispensed by the pump 2 is recorded on the indicator while the other pumps and meters are held inoperative. The pulse transmitters may comprise cams on the shafts 14, 14A, operating make-and-break switches or endless tracks on rotating discs or drums, which tracks are composed of alternate conducting and non-conducting segments co-operating with a follower. Alternatively, the tracks may impart mechanical movement to a stylus which generates pulses. The counters 33, 34 may be geared together, and operated by a single set of pulses, or they may be separate and operated by separate pulse trains from a transmitter. The lay-out of an electric circuit for an installation with four metering stations is shown. Specification 909,682 is referred to.

Title: Improvements in the transfer mechanism of calculating machines
IPC: G06C15/38
Filed: 1920-07-08
Abstract: 169,178. Reisser, A. Aug. 21, 1913, [Convention date]. Transfer mechanism for machines of the Odhner type having two totalizing counters. Transfer is effected in the quotient and second counter by two-toothed discs 18, Fig. 6, which, when engaged by the transfer stud on the counter wheel, are thrust along their squared shaft laterally against the action of blade springs 23. This brings the disc affected into the path of the next higher wheel, where it is held by a spring pawl 22 engaging an eccentric groove 19 in its hub, until rotation of the shaft 16 effects the transfer. The spring pawls 22 escape from the locking grooves at the outer part of the eccentric, and the springs 23 slide the discs to normal position. The teeth on the discs 18 are differently spaced in gradation so as to effect transfer successively from lower to higher denomination for either direction of rotation. Only one of the two series of helically arranged teeth 18 comes into action in an operation of the machine.

Title: A device for ascertaining the ratio in percent between the speeds of rotary members of machines
IPC: G01P3/60
Filed: 1954-08-27
Abstract: 782,575. Counting-apparatus. LICENTIA PATENT - VERWALTUNGS - GES. Aug. 27, 1954 [Sept. 10, 1953], No. 24982/54. Class 106 (1). Two counters A21,A22, Fig. 1, can be selectively connected via a selector switch A53 to pairs of contact devices A41-A46 which are individually associated with separate rotary members. The two selected contact devices send impulses corresponding in number to the speeds of their associated rotary members, to the counters A21, A22. In the supply circuits of the counters is a normally closed switch a23 of a relay A23 and a switch A51 which is closed during operation of the counters. When the counter A21 reaches a predetermined number, say one hundred, the switch A211 is closed to energize the relay A23 which opens its switch a23 and so disconnects the supply from the counters. An indication is thereby given of the percentage ratio of the speeds of the two rotary members. Closure of a normally open switch A52 at any time results in energization of the relay A23 and consequent interruption of the counting. More than two associated counters may be provided. A lamp Z9 indicates that the main switch Z5 is closed and a lamp A9 indicates operation of the counters.

Filed: 1952-10-06
Abstract: 714,129. Thermal switches; switches held set and freed mechanically. GENERAL ELECTRIC CO. Oct. 6, 1952 [Oct. 5, 1951], No. 24984/52. Class 38(5) [Also in Group VI] In an automatic toaster of the " pop-up " type, the main switch comprises a fixed contact 89 mounted on a plate 6 and a contact 92 mounted on a spring switch blade 91 carried by the free end of a spring arm 93 so that contact 92 is normally biased towards contact 89. Lever arm 37, by means of which the toast racks are lowered and raised, has an arm 94 which, when the racks are raised, engages an arm 97 secured to the end of the switch blade to hold the switch open. The toasting is timed by a bimetallic element 63 pivoted on a bracket 65 and having its free end resting against, an adjustable screw 66 at the free end of a pivoted arm 67 whose position is controlled by a manually operated lever 70. Element 63 is heated by an insulated winding 74 connected to spaced contacts 75, 76 on insulated brackets 77, 78. A resilient leaf spring 'switch blade 81 having one end fixed carries contact buttons to engage contacts 75. 76 and is biased towards contacts 76 but normally held in contact with contact 75 by an arm 84 which engages the free end of blade 81. Switch arm 84 is pivoted at 85 on post 26 and has a hook 86 at its lower end. On heating, the bimetallic element 63 bows upwards until hook 86 engages under the element, Figs. 3 and 5, and arm 84 moves to allow the contacts on blade 81 to disengage from contact 75 and engage contact 76 thus cutting the windings 74 out of the heating circuit. The element 63 then cools down and, being held by hook 86, its end rises, as it straightens, and engages an arm which releases the toasting racks and hence also opens the main switch breaking the heating circuit. Specifications 714,130 and 714,131, [both in Group VI], are referred to.

Abstract: 584,201. Self-closing folding doors. ROCHESTER, L. H., and HAYWARDS, Ltd. Dec. 14, 1944, No. 25069. [Class 65 (i)] Self-closing double doors are equipped with devices for securing the closing of the two leaves in proper sequence. A shaft C above the doors carries two arms A, B. In the normal position, the arm B lies in the path of the leafY and stops the leaf when it moves to a partly-closed position. The arm A lies in the-path of an inclined plate D on the leaf X and as that leaf moves to the fully-closed position, a roller A<1> on the arm A rides up the plate and turns the shaft C so as to remove the arm B from the leaf Y which is then free to move on to the fully-closed position. The doors are held in the open position, shown in Fig. 2 in full lines, by hooks E which are held up in the engaging position by a common cord G and springs H. This cord includes a fusible element J which serves to release the hooks in case of fire. The doors may be mounted on rising butt hinges K or may be closed automatically by any other means when released.

Title: Methods of varying carrier mobility in semiconductive bodies
IPC: H01L21/00
Filed: 1961-07-12
Abstract: 928,562. Semi-conductor devices. WESTERN ELECTRIC CO. Ltd. July 12, 1961 [July 18, 1960], No. 25221/61. Class 37. In making a semi-conductive device containing at least one PN junction a directional elastic strain is produced and maintained in the semiconductive material and if of a magnitude such that the carrier mobilities in the material are altered by at least 15%, the strain direction being aligned with respect to a crystallographic direction of the material. A theoretical discussion of the effect is given and includes data relating to the choice of the strain direction. In the mesa-type transistor shown in Figs. 2 and 3 the stressing of the P-type germanium wafer 5 serving as the collector communicates a compressive strain to the N-type base region 11 bearing a heavily doped P-type base contact 12 and an N-type emitter region 13 and simultaneously increases the mobilities of electrons in the direction across the base zone and of holes in the plane of the zone. The three other embodiments described, Figs. 4, 5, 6 (not shown) are a NPN transistor, a PNP mesa-type transistor, and a P+NN+ varactor diode, and these are stressed in differing ways: the plane germanium wafer of the NPN transistor is hard soldered at its ends to the surface of a block which is bent about a fulcrum to apply tensile strain to the wafer; the P-type collector wafer of the PNP mean-type transistor is hard soldered to the end face of a metal pin held under biaxial radial compression and the force on the pin them removed thus applying biaxial tension to the wafer and the N-type mesa on its other surface; the base region of the varactor diode is hard soldered or otherwise attached to a heated bar which is then allowed to cool, thus setting up a compressive strain in the diode. Semiconductive materials suitable for using the effect are:- Si, Ge, InSb, PbTe, GaSb, AgSbTe 2 , AgSbTe, Cu 3 AsS 4 , Cu 3 AsS 3 , Cu 3 SbS 3 , Bi 2 Te 3 , Bi 2 Se 3 , Sb 2 Te 3 , PbSe, CdS, ZnO, AgSbSe 2 .

Abstract: 909,748. Television. DESURMONT, R. July 25, 1960, No. 25879/60. Class 40 (3). [Also in Group XX] The picture reproduced by a television tube 2 (Fig. 1) is viewed by reflection at the surface of a polished plate 3 of transparent or opaque synthetic resin which may be tinted with a colour such as black or green. The plate 3 absorbs some of the picture light and this is stated to result in a picture of more acceptable contrast and to be substantially free from flicker. The reversal of the picture caused by reflection may be corrected by reversing the scanning direction of the tube beam. Alternatively, correction may be effected by producing a double reflection by means of an intermediate mirror 4 (Fig. 2) which together with the plate 3 may be carried by an independent support as shown in Fig. 3.
