Title: Control system for lifts with automatic doors
IPC: B66B13/14
Filed: 1962-07-17
Abstract: 1,004,617. Lifts. INVENTIO A.G, July 17, 1962 [July 26, 1961], No. 27425/62. Drawings to Specification. Heading B8L. In an electrical control system for a goods lift, at each floor a combined car-summoning and shaft door controlling push-button switch is provided, which switch is effective to summon the car from another floor only when all the shaft doors are closed. The door-drive control means includes a bi-stable switching arrangement which, in one stable state, effects closing and, in the other stable state, effects opening of the shaft door. When the car is stationary at a floor, the switching arrangement is alternately brought from one stable state to the other each time the floor button at that floor is pressed. If a shaft door is left open, a first pre-set time delay relay actuates a warning bell and a second pre-set time delay relay initiates closing of the door, the relays being connected to the control system in such a way that if the floor button is pressed before the doors close, the doors re-open and the time delay relays are reset. A control circuit is described in detail for a lift serving three floors.

Abstract: 1437012 Lamp failure alarms WESTFALISCHE METALL INDUSTRIE KG HUECK & CO 11 June 1973 [9 June 1972] 27673/73 Heading G4N [Also in Division H2] An arrangement for monitoring the failure of a load in a plurality of parallel connected electrical loads e.g. vehicle lamps 5-8 or other electrical loads comprises a resistance 9 in series with the loads and arranged to dissipate heat energy to a further element 10 sensitive to a change in the rate of heat energy dissipation for indicating a change of the load current. The arrangement may be used in a flashing direction indicator using a pulse generator 1 and a relay contact 3 actuated by relay 2 for switching the current between the loads 5, 6; 7, 8. When any one of the lamps 5-8 fails, the current through the element 9 and hence the energy dissipated by it increases which is sensed by a temperature sensitive element 10 to alter the repetition rate of generator 1 output or to activate a warning lamp (not shown). The arrangement may alternatively be used to monitor other electrical loads, e.g. brake lights, with elements 1-4 replaced by other forms of indication.

Title: Fluid pressure brakes
IPC: B60T17/10
Filed: 1922-10-13
Abstract: 204,911. Scott, R. Oct. 13, 1922. Fluid-pressure. - In a fluid-pressure brake system of the type in which the brakes are applied by a fall cf pressure in the train - pipe, the brakeactuating piston C, which moves in the brake cylinder A, is provided with a skirt S forming the cylinder of a fixed piston F integral with the air reservoir B. The brake rigging is attacked to lugs on the movable piston C which project through slots in the cylinder A. A non-return valve D is fitted in the head of piston C. When the pressure falls in the train-pipe L, the valve D closes and the piston C is forced outwards by the pressure in the reservoir B. When the pressure in the pipe L is restored, air passes through the valve D and re-charges the reservoir E. The piston C returns to the " brales-oft " position by reason of the difference in areas of the piston C, F.

Title: Improvements in or relating to the generation, transmission, and distribution of electricity
IPC: H02H3/28
Filed: 1919-11-11
Abstract: 155,095. Hawkins, H., Hanstock, W. H., Higgs, A. H., and Ferranti, Ltd. Nov. 11, 1919. Protective arrangements.-In a protective system for an alternating-current network, iron-core ring transformers are arranged at both ends of each protected feeder, the secondaries being connected in a pilot-wire circuit with relays to cause the operation of the circuit-breakers. Parallel three-core feeders a, a<1> are shown in Fig. 1 with oil switches b, b<1> at their ends, and with ring transformers c, c<1> of the type described in Specification 12685/09. If a fault occurs in a core of cne of the feeders, the unbalanced current induces an electromotive force in the transformer secondaries. This causes a current to flow in the pilot circuit to operate the relays e, thereby closing the trip circuits of the oil switches b or b<1>. The switches on the healthy feed are not operated as the currents in the transformer secondaries on that feeder oppose each other.

Title: Method of determining the distance travelled by a vehicle with respect to a reference surface
IPC: G01S15/60
Filed: 1974-06-24
Abstract: 1450459 Doppler navigation system INSTITUT FRANCAIS DU PETROLE 24 June 1974 [28 June 1973] 27931/74 Heading G1G A method for determining the distance travelled by a vehicle over a signal-reflecting surface, from the Doppler effect on signals transmitted and received along at least one direction inclined with respect to the surface, is characterized in that (a) the transmission consists of a series of pulses whose recurrence period varies and is shorter than the go-andreturn travel time of the pulses and (b) the signal frequency varies within each pulse. In the acoustic ship's log embodiment described, frequency-shift-keying is used within each transmission pulse, the pulses recur at quasi-random intervals making up a series which repeats, and the series is such that the probability of transmission and echo reception instants coinciding is low. Each transmission pulse has the same length, comprises a whole number of carrier-wave cycles, and is identifiable by its frequency content. When the echo associated with a given transmission pulse has been identified, by frequency-content matching, the duration of a given component frequency burst within the echo is compared (by a clockpulse counter) with the duration of the corresponding frequency burst  within the transmission pulse or within the echo received along a second, oppositely inclined direction. The duration difference depends on the ship's speed. The duration differences for each such component burst are summed to give a measure of the distance travelled.

IPC: B24B3/02
Filed: 1952-11-06
Abstract: 719,010. Relieving gear cutters. GLEASON WORKS. Nov. 6, 1952, No. 27998/52. Class 60. [Also in Group XXII] A method of simultaneously relieving the side surface 31, Fig. 3, and the tip surface 32 of a face-mill gear cutter blade supported in a head 24, Fig. 6, comprises engaging the blade with a rotating profiled grinding wheel 40 and effecting a relative helical motion between the wheel and the head about and in the direction of the axis 25 of the head thereby to grind the surfaces 31 and 32 as helical surfaces coaxial with the head, the axis 45 of the wheel lying in a plane 61, Fig. 9, normal to the helix curve through a point 50 on one of the surfaces 31, 32. The plane 61 is inclined at the helix angle 58 to a horizontal plane 60 through the axis 25 and the point 50. In the preferred embodiment, the head 24 is mounted on a spindle 70, Fig. 10, which is simultaneously rotated by gears 82, 83 and reciprocated by a cam 80 to produce a helical motion. The grinding wheel is journaled in a head 90 slidably adjustable at right angles to the wheel axis on a carrier 92 to permit compensation for changes in wheel diameter. The carrier 92 is in turn mounted on a laterally-adjustable head 94 for angular adjustment about an axis that lies in the same horizontal plane as the axis of the spindle 70 and is at right angles thereto. A diamond pointed tool 93 for dressing the wheel is mounted on the carrier 92. The wheel surface, which may have a portion 42 to produce a rounded edge between surfaces 31, 32, is in tangent contact with the blade surface in the region close to the plane 61. Contact, however, is not restricted to this region so that there is a slight difference between the wheel and blade profiles which is taken into account during dressing. Curved profiles, such as those of spherical cutters, may also be ground. Where outside and inside cutting blades are mounted alternately in a single head, two grinding wheels are provided each of which is adapted to treat the cutting side of one kind of blade and the non-cutting side of the other. Alternatively, the non-cutting sides may be ground by conical or cylindrical wheels. Alternate blades are removed prior to grinding and the head is double-indexed.

Material on surface 1 is scraped and deposited in discharge opening 2 by scraper 4, the scraper being furnished with two scraping edges 5a, 5b. The scraper carries racks 13 driven by gearwheels 12 so that the scraper reciprocates backwards and forwards over the surface. The scraper is furnished with hooks 7a, 7b which co-operate with fixed guides 6a, 6b. In the position shown, hook 7a hooks on to the guide 6a so that the scraper is swung such that scraping edge 5b engages and scrapes the surface 1 as it goes to the left. At the end of its leftwards movement, hook 7a slips off the guide 6a to allow edge 5a to drop on to stop 10a. Gears 12 then reverse direction, and scraper 4 moves to the right, the scraping edge 5a falling off stop 10a on to the surface 1, and hook 7b engaging slide 6b to lift scraping edge 5b off surface 1. The result as the scraper moves to the right is for scraping edge 5a to engage and to scrape surface 1. The scraping edges therefore work alternately to discharge material centrally into discharge opening 2.
