Abstract: 456,988. Current and pressure meters. NALDER BROS. & THOMPSON, Ltd., 97, Dalston Lane, and LIPMAN, C. L., 9, Stamford Grove East, Stamford Hill, both in London. May 21, 1935, No. 14842. [Class 37] [See also Group XXXVII] A permanent magnet moving - coil measuring instrument or relay has a bar magnet carrying a supporting member, which may be a magnet, extending across an end face of the first magnet and spaced therefrom to form an airgap in which the coil moves and embraces the member. The magnet may have a varying cross-section and may have polepieces of soft magnetic material. Materials of high coercivity such as aluminium-nickel and aluminium-nickelcobalt alloys may be used, and these may be magnetized longitudinally or across their diameter. Fig. 1 (Prov.) shows a cylindrical magnet Mo and an annular magnet Mi spaced by a magnetic washer W and clamped in a frame F, the moving coil C being balanced by the pointer P. Adjustment of the gap G can be effected by shims under the magnet Mo or by changing the washer W. The magnet Mo is magnetized across the diameter Y, Y giving a flux distribution indicated in Fig. 5 (Prov.), or it may be slotted at one side and magnetized across a line at rightangles to Y, Y. The magnet Mi is also slotted at one side to permit assemblage of the coil C, and, as in Fig. 9 (Prov.), it can have a tapering cross-section. The washer W can be integral with either Mo or Mi. In a modification, a second magnet Mo is arranged above the coil C giving an instrument of greater sensitivity. The bores of the magnets may be enlarged to permit illumination of the dial from behind. In Fig. 12 (Prov.), the magnet Mo is magnetized longitudinally giving a flux distribution shown in Fig. 16 (Prov.), and the part Mi is either of soft-iron, in which case the frame F is magnetic, or is a permanent magnet. The magnet Mo may comprise two separate half cylinders, and one form of the part Mi is shown in Fig. 21 (Prov.), with its flux distribution. An edgewise instrument, Fig. 23 (Prov.), has the part Mi lying in a recess in the magnet Mo. Damping is effected by the aluminium or copper coil former, or by a metal disc on the instrument spindle. Fig. 1 (Comp.) has a polepiece I on the magnet Mo, the part Mi being secured by screws E by which the moving system, Fig. 3 (Comp.), can be readily detached. The moving system can be pivoted eccentrically with respect to the magnets to give a desired scale law.

Title: Pay television system
IPC: H04N7/173
Filed: 1964-11-11
Abstract: 1,026,919. Electric selective signalling. HAZELTINE CORPORATION. Nov. 11, 1964 [Dec. 23, 1963], No. 45953/64. Heading G4H. In a pay TV system, coded interrogation signals are supplied to receiving means each of which includes means to send back a signal representative of a programme payment acknowledgement and of the programme corresponding thereto in response to an individual one of said interrogation signals and to enable reception of a TV programme on receipt of a coded payment acknowledgement reply signal. In the particular embodiment, a central station addresses receivers in turn by transmitting an address comprising 3 out of 41 frequencies along a coaxial cable. A receiver at which a customer has selected a pay TV channel and placed coins in a coin mechanism, responds to receipt of its address by sending one out of 3 frequencies characteristic of the channel and one out of 3 frequencies characteristic of the amount paid along the coaxial cable to the central station where, provided the amount paid is correct for the channel selected (decided by AND gates fed by detecting filters), the following happens: (a) the address is sent again to the receiver to allow the TV programme to be received, (b) the address and channel are punched on tape, (c) the appropriate one of three channel counters is incremented to give a visual display of programme popularity. The central station then proceeds to the next address. The TV programmes are also transmitted along the coaxial cable. Radiation from an antenna may replace the cable. The data, price and time are also punched in the tape. It is mentioned that change in the setting of the channel selector at the receiver during reception of a programme will terminate such reception. A pilot frequency may be transmitted at the end of the programme to terminate reception. The coin mechanism may be dispensed with in the case of credit customers in which case a single frequency (present or absent) replaces the one out of 3 selection indicating the amount paid.

Title: Brake control assembly
IPC: B60T8/50
Filed: 1975-11-06
Abstract: 1483289 Antiskid skid brake modulators AISIN SEIKI KK 6 Nov 1975 [12 Nov 1974] 46004/75 Heading F2F In a brake control assembly having a servomotor 11 comprising a diaphragm piston 31 dividing a casing into first and second chambers 34, 35 and being operatively connected to a control plunger 25 of a brake cut-off and pressure modulator valve 10, a valve arrangement 12 for connecting the first chamber 34 to a source of higher pressure than that in the second chamber 35 to cause piston movement and hence operation of the modulator and for connecting the first and second chambers to the same source of reduced pressure to permit normal brake operation, there is also provided a oneway valve 13 permitting substantially free fluid flow from the second chamber and a by-pass passage for permitting only restricted fluid flow past the one-way valve out of the second chamber 35. As shown the by-pass passage is a narrow orifice 60 formed through valve 13, Fig. 4. In normal braking operation with skid conditions absent no current flows through the solenoid 36 of valve 12 and reduced pressure is applied to chamber 34 causing piston 31 to be urged to the left by spring 33, opening the cutoff valve 24 to provide free communication between the master cylinder and wheel cylinders. When a skid condition is sensed valve 12 is operated to supply air at atmospheric pressure to chamber 34 and displace piston 31 against spring 33 so that, as plunger 25 moves, cut-off valve 24 is closed and the volume of a chamber 28 is increased to lower braking pressure. When braking is restored chamber 35 communicates with the vacuum source only via orifice 60 and the extent to which vacuum is introduced to chamber 35 is thus limited so that the rate of pressure increase at the wheel cylinders is rapid at first and then becomes gradually slower.

Abstract: 1334567 Semi-conductor switching circuits INTERNATIONAL BUSINESS MACHINES CORP 8 Oct 1971 [30 Oct 1970] 46976/71 Heading H3T [Also in Division H1] A switching circuit (Fig. 3) with a characteristic resembling that of a PNPN switch consists of a pair of cross-coupled FETs as shown. An equivalent arrangement comprises a pair of conductive channels of opposite conductivity type each of which acts as a gate for the other, the drain of each channel being connected via a load to the source of the other and a control electrode attached to one of the drains. In one embodiment the loads are resistors. In another, in which an insulating layer may be disposed between the channels, they are diodes while in the preferred embodiment they are Schottky diodes which may be integrated with the field effect element as shown in Fig. 7. The P channel is formed by diffusion into an N layer epitaxially deposited on a highly resistive substrate. To optimize the switching characteristic, the channel thicknesses d 1 , d 2  and doping should be equal. Doping equality can be achieved by ion bombardment while the thickness d 1  may be adjusted by a continuously monitored etching step. Aluminium and gold are deposited as shown to form ohmic contact to the N and P channel respectively and Schottky contact to the other channel, while an aluminium control electrode is provided on the N layer. Both channels are switched from the off to the on state by a pulse which forward biases the gate junction, reversion occurring when the current falls below a holding value.
