Title: Motor vehicle provided with an auxiliary registration plate
IPC: B60R13/10
Filed: 1974-08-27
Abstract: 1482746 Signs M DUNBAR and J. J FITZGERALD 27 Aug 1974 [2 Oct 1973] 45914/73 Heading G5C [Also in Division B7 and E1] A detachable auxiliary registration plate for application to a fluorescent or luminous zone of a motor vehicle is reducible in length to facilitate carrying thereof when removed from a parked vehicle, it being intended that all vehicles should display such an auxiliary plate while being driven by an authorized user. On parking, the driver detaches and collapses the plate to keep on his person so that driving of the vehicle without this plate will indicate theft thereof, the auxiliary plate bearing the same registration number as the standard front and rear plates of the vehicle. Alternatively or additionally, the presence of the auxiliary plate indicates that the vehicle is insured. The auxiliary plate may consist of a number of hingedly connected sections or telescoping sections or be composed of a flexible material which can be rolled up. For attachment to the vehicle, means such as brackets, press studs, clips or magnets may be employed. At least some of the registration indicia on the plate may be coloured to match the vehicle.

Abstract: 1356146 Continuous casting; casting ingots ALLMANNA SVENSKA ELEKTRISKA AB 4 Oct 1971 [4 Dec 1970] 46018/71 Heading B3F [Also in Division F4] Steel is tapped from a container, such as a heating ladle 12, through a closable valve 15 into a mould 21 or 31 through a hot refining slag layer 28, e.g. molten calcium fluoride, to be refined and cast. Graphite or alloying-material electrodes 24 for heating the slag 28 surround a ceramic pipe 23 which protects the steel flowing into the slag. In continuous casting, a bottom plate 25 is lowered by members 27, e.g. automatically according to a measuring device in the mould 21. For ingot casting, a mould, Fig. 3, with a bottom 30, is lowered by a table 32 as pouring and solidification proceed. Castings may be four-sided, round or tubular. The steel may be vacuum-treated while inductively stirred in the ladle 12 and then refined and alloying constituents added while it is heated by arc electrodes 13 at atmospheric or sub-atmospheric pressures of protective gas. Stirring may be by gas or mechanical means. There may merely be induction or resistance heating. The on-off valve 15 may be electromagnetically operated and be followed by a magnetic circuit 17 and an electric conductor 18 with gaps across the path of the steel stream so that according to the direction of the magnetic field and/or current flow, a force is generated in the stream with or against it, to regulate the teeming rate. Current passing through the melt between an electrode 19 and the conductor 18 prevents solidification in the ladle outlet.

Abstract: 1,169,362. Automatic exchange systems. MINISTER OF TECHNOLOGY. 3 Nov., 1966 [4 Nov., 1965], No. 46752/65. Heading H4K. A digit receiver, for use in an exchange system, comprises a multistage shift register into which incoming digits, after translation into binary form, are successively fed and a number detector which on recognizing that a four digit number contained in the register represents a local subscriber initiates the operation of a pair of crosspoints in a relay switching matrix so as to connect the calling and called parties together. A herald digit is inserted in the register a fixed number of bit positions in front of the dialled digits and the number detector is held inoperative until this herald digit is shifted to a particular bit position. If the stored number does not correspond to a local number, a trunk supervisory device is seized, so that a time slot on a TDM trunk to an adjacent exchange can be allotted to the call, and the caller can be connected via the matrix and a multiplexer to the trunk. The identity of the slot is entered in the register which is then read-out to the trunk during a supervisory time slot (i.e. effectively an order wire). At the other exchange, the time slot identity and the wanted number are used for operating another crosspoint array. Each bit of the identifying information is read-out from the shift register eight times before it is deleted and a majority decision circuit is used at the receiving exchange for processing each such set of eight bits prior to inserting the "most likely" bit into another shift register. Each line is provided with its own supervisory circuit which, inter alia, transmits dialling signals (in variable carrier frequency, or variable amplitude form) to a coder which converts each digit into a 7 bit binary code. The switching network is effectively of the folded variety where all the inlets and outlets are located on the same side. Logic circuitry, for controlling the shift registers and switching network during the normal phases of loop closure, dialling tone reversion, dialling, speech, hang-up (by either party) and premature release (i.e. prior to, or during dialling), is provided.

Abstract: 1,153,234. Valves. VAPOR CORP. 17 Oct., 1967 [24 Jan., 1967], No. 47176/67. Heading F2V. A valve for controlling the flow of high pressure fluid and adapted to have a fully closed, intermediate, and fully open state, comprises a housing 12 having disposed therein, and between an inlet 16 and outlet 26, a chamber 28, the chamber being defined by a conical wall portion 31, a cylindrical wall portion 30 and a piston 38 which is slidable within the cylindrical portion. The piston is biased by a spring 54 and fluid pressure within the chamber, which pressure is derived from the inlet via a restriction 32, into a position in which an extension 40 formed integrally therewith engages a seat 24 so closing the valve. Upon actuation of a solenoid operated valve 58, the chamber pressure is partially relieved via passage 56 so permitting the inlet pressure to move the piston into the chamber, the degree of movement being limited by a piston stem 48 which eventually obturates passage 56 and so serves to retain the valve in its intermediate position (Fig. 2, not shown). To bring the valve into its fully open state, a second solenoid valve 64 is actuated so permitting the chamber pressure to be fully relieved and the piston to move further into the chamber until it abuts a stop formed by the stem housing 46 (Fig. 3, not shown). In a modification, the cylinder may be vented to a point downstream of the outlet rather than to atmosphere.
