Patent GB-1518953-A (GB)
Title: Charge coupled dircuit arrangements and devices
IPC: H01L21/339
Filed: 1975-09-05
Abstract: 1518953 Charge coupled devices MULLARD Ltd 5 Sept 1975 36701/75 Heading H1K In a CCD comprising a region of one conductivity type in which charge carriers can be stored and transported signal information is converted into an input of charge carriers into a storage region immediately ahead of the first transfer electrode by the punch through of a depletion region, the extent of which is controlled by voltage on an input gate electrode, to a rectifying barrier bounding a further region in the body constituting a source of said charge carriers. Two groups of embodiments are described respectively employing surface transfer to minority carriers and transfer of majority carriers along a buried channel. In the first of these, designed as described for two phase operation, unidirectional transfer is ensured by provision of heavily doped ion-implanted inclusions of the same conductivity type as the transfer channel beneath the leading edges of the transfer electrodes. In one form the channel is formed on a substrate of the opposite conductivity type acting as the source region, and, to permit non-destructive read-out of charge, alternate transfer electrodes may optionally each be of annular form and constitute the gate of a deep depletion FET with a central drain electrode and a source constituted by the bulk of the channel region, the charge stored under the transfer electrode determining the conductance of the FET channel. In the other form the depletion region extends through a more heavily doped portion of the channel region, formed with the inclusions, to reach an implanted buried source region of the opposite type having an upward extension to a contact on the surface. A similar structure is present in one version (Fig. 6) of a three-phase buried channel embodiment but in this case punch through is between source region 37 and the buried channel region at the point where the extent of the depletion region associated with the reverse based channel isolating junction 39 is controlled by the voltage on the input gate 36. In the other version the source region is a surface region laterally spaced from the leading edge of the channel region. In all cases the input is in the form of square pulses, synchronized with the clock voltages and in antiphase with that applied to the first transfer electrode, superimposed on a direct voltage just less than the punch through voltage, to give a stored charge which is noise insensitive and varies linearly with the input voltage amplitude.

Abstract: 1521464 Cooling component assemblies THORN AUTOMATION Ltd 15 Oct 1975 [31 Aug 1974] 38168/74 Heading H1R A cooled rack for mounting modular enclosures of electrical equipment comprises a metal angle framework carrying top, bottom, and side panels and lateral cross-members supporting angular guides which carry equipment modular enclosures inserted from the front (Fig. 1, not shown). Hollow cooling plates 20 (Fig. 2) are mounted one per shelf along the back of the rack to contact the rear of each; and liquid coolant is circulated through the plates from an inlet manifold 23 to an outlet manifold 24. The latter are interconnected by a closed circuit pump 26 and heat exchanger 25 air cooled by fan 27. Each modular enclosure (Fig. 3) is enclosed in a case 30 with a thick conduction plate 31 at the rear thereof contacting the cooling plates 20, which contains end embedded isothermal heat pipes 32 supported also by a plate 33 at the front of the module. These support conduction members 34 on which heat generating components 35 are mounted. Other isothermal heat pipes 36 are secured to the outer surface of plate 31 to engage grooves of the cooling plate 20 (Fig. 4, not shown). The modular enclosures are clamped in position (Fig. 5) by rubber blocks 40 on rear cross members 15, and rods 41 passing therethrough project from the ends to locate in forked ends of pairs of levers 43. These are slidably located with respect to the enclosure by studs 44 of the latter engaging elongated holes 45 of the levers, which are also slidable with respect to actuator plates 46 by stud 47 engaging an elongated hole 48 of each lever 43. Each actuator plate is slidably located to the modular enclosure by three studs 49 thereof, passing through parallel slots 50 of the plates, which carry toothed racks 51 adjacent the front of the enclosure co-operating with toothed segments 51 carried by a handle 53 pivoted adjacent the front thereof (Figs. 5, 6). When the modular enclosure is located in the rack the ends of rods 41 are located in the forked ends of levers 43 with the handles 53 in the downward position and plates 46 in their forward position. Rearward movement pivots the levers 43 about the ends of rods 41 until they reach a clamped position in which the rubber blocks retain the enclosure against the cooling plates, and for removal handle 53 is pivoted downwards so that the resulting movement of the actuator plates pivots levers 42 about rods 41 into disengagement, enabling the modular enclosure to be withdrawn. The rack may be wired for interconnection of several modular enclosures automatically on insertion, and identifying grooves and keyways may be provided to ensure correct insertion. Thermal contact may be made directly between the conduction plates and the cooling plates. Alternatively the cooling may be convection air or gas flow.

Abstract: 841,464. Road-vehicle hydro-pneumatic suspension systems. ALLINQUANT, F. S. Nov. 27, 1958 [Nov. 28, 1957; Nov. 6, 1958], No. 38373/58. Class 108(2). A hydro-pneumatic spring suspension unit 8 (Fig. f) in a vehicle wheel suspension has its pneumatic chamber formed partly from the upper volume of the unit 8 and partly by a separate chamber 10 connected by a tube 9 with the unit 8. The chamber 10 is divided by a partition 12 (Fig. 2) into a working chamber 16 and a reserve chamber 17. Formed in the partition 12 is a differential piston 19, 20, adapted to be driven by an electric motor 37. Seals 22, 23, permit flow of air in a direction from the chamber 16 to the chamber 17 only. The action of the pump 19, 20, is thus to drive air from the chamber 16 to the chamber 17 when driven by the motor 37. A valve 28 permits flow from the chamber 17 to the chamber 16 when lifted by the action of a solenoid 41. The motor 37 is energised by the closing of a relay 45 and the solenoid 41 is energised by the closing of a relay 46. The relays 45, 46, are of the delayed action type and are energised when the suspension links 2, 3, carrying the road wheel 5 move in one direction or the other from a normal position so as to bring a contact 51 into engagement with respective contacts 52, 53, carried by the vehicle frame 1. In a modification (Fig. 3), the motor 37 is disposed outside the chamber 10. Instead of the solenoid 41 the valve 28 is operated mechanically by a link 57 connected to a brake band 55 which is in engagement with a drum 54 carried by the shaft of the motor 37. In this arrangement the valve 28 is thus opened by rotation of the motor 37 in one direction only. The pump is operated continually since it functions for either direction of rotation of the motor 37. Instead of the brake band 55 operating the valve 28, a free-wheel mechanism may be employed. In a further modification (Fig. 6), there are two pumps driven by respective connecting rods 87, 87<SP>1</SP>, coupled to gear wheels 85, 85<SP>1</SP>, driven by a gear train from the driving shaft of the motor 37. Each pump comprises a cylinder 93 mounted in the partition 12 and in which works a piston 101 connected to the connecting rod 87, on rotation of the gearchamber 16 through a non-return valve 96 and on the down stroke of the piston is forced through a valve 105 in the piston. Return flow from the chamber 17 to the chamber 16 is provided by a port 111 in the partition 12 controlled by a valve 119 held in closed position by a spring 117. A shoulder 121 carried by the valve 119 is adapted to be lifted by a finger 124 mounted on a pivot 123. This occurs when an arm 125 rigid with the finger 124 is engaged by a pin 126 carried by the connecting rod 87<SP>1</SP>, on rotation of the gearwheel 85<SP>1</SP> in a direction opposite to that of the arrow f.
