Patent GB-1329287-A (GB)
Title: Circuit patterns on substrates
IPC: H01L49/02
Filed: 1970-12-15
Abstract: 1329287 Coating with metals WESTERN ELECTRIC CO Inc 15 Dec 1970 [15 Dec 1969 16 July 1970] 59471/70 Heading C7F [Also in Division H1] A method of making a circuit on a non conductive substrate comprises depositing an intermediate layer on the substrate, forming a circuit pattern on the intermediate layer and then removing the exposed areas of intermediate layer wherein the intermediate layer is produced by forming an adherent discontinuous deposit of a normally etch resistant material on the substrate and then forming a continuous etchable material layer over the discontinuous deposit.  The composite layer bonds the circuit pattern to the substrate and the discontinuous nature of the normally etch resistant layer allows it to be etched along with the continuous deposit without damaging the substrate. The substrate may be a ceramic material (e.g. alumina), the discontinuous deposit may be palladium and the continuous deposit gold. The circuit pattern may be formed from copper, a photo resist exposed through a mask forming a negative of the circuit pattern. The deposition of discontinuous material is monitored using the resistance of the deposits, for optimum results, material is deposited for a time not greater than that required to reduce the sheet resistance of the substrate to 10<SP>6</SP>#<SP>α</SP> and not less than that required to begin to reduce the sheet resistance of the substrate. Palladium chloride solution may be used to deposit the palladium on a substrate sensitized with stannous chloride, potassium trichloride being the etch used. [An etchable material is defined as one which may be etched completely away without causing damage to the circuit pattern]

Title: A hermetically sealed multiple glazing
IPC: E06B3/54
Filed: 1978-07-25
Abstract: A glass insulating unit comprises at least two glass panes and spacers 3 in the form of hollow elongate members having mitred ends and provided on their surfaces facing the panes with an adhesive 4. In order to make a hermetically sealed joint between the spacers and the panes, a corner member 1 having two perpendicular arms is inserted into the ends of the spacers at each corner of the unit. Each corner member is formed at least partly of a pliable heat meltable material 2 which is of external cross-sectional area larger than the internal cross-sectional area of the spacers. During insertion, this material is pressed out and fills up any clearances at the corner. The spacers and corner members are then heated and the resulting expansion of the spacers causes their mitred ends to be pressed together so that the material adheres to the ends. <IMAGE>

Title: Decomposition of phosgene
IPC: B05C5/04
Filed: 1978-07-28
Abstract: Phosgene or phosgene-containing gas are produced as waste gases in industry and have to be treated before being emitted. Treatments to remove or decompose the phosgene have been to wash with alkalis or to pass the waste gas over active carbon sprayed with water. The former provides a further effluent to be worked up and the latter process is easily inactivated by other substances present in the waste gas. The present invention provides a process for the decomposition of phosgene by hydrolysis wherein the phosgene is dispersed in water or water containing an acidic gas.

Title: Apparatus for safeguarding automatic coin collection machines against fraudulent actions
IPC: G07F1/04
Filed: 1978-09-29
Abstract: Apparatus for safeguarding automatic coin collection machines against an inserted coin 2 being pulled out by means of a thread 3 secured to the coin 2, the apparatus including a U-shaped lever system in the coin passage 1, to cause a clamping action. An opening 19 in the wall of the coin passage 1, which wall is opposite to an end member 7 of the lever system, is larger than the thickness of the end member 7, by less than the thickness of the thread 3. In the rest condition, the end member 7 is held outside the coin passage 1 by means of a spring 17, and it is connected to a second mounting bar 10, movable by a solenoid 16, by a pivotal lever 12. When the coin 2 passes a detector 13, 14, the solenoid 16 is energised and moves the first end member 7 towards the opening 19, and the second end member away from the coin passage 1. The dimensioning of the opening prevents member 7 getting stuck in the opening whilst still preventing retrieval of the coin. Also since the member cannot enter the opening the end member 8 of the second mounting bar 10 does not clear the passage 1. <IMAGE>
Patent GB-2016831-A (GB)
Title: Power supply systems
IPC: H02H7/20
Filed: 1979-02-09
Abstract: Failsafe primary power control apparatus is provided which includes a backside contact of a control relay in series with the power relay which is held open until the initial program load and latch reset is finished. The system also includes a timer which is initiated by a power fault condition signal which is simultaneously applied to the processor. If the processor is capable of handling the fault condition, it puts out a signal which stops the timer. If the processor is not capable of handling the fault, the signal to the timer is not produced and, accordingly, the timer runs the full interval. This causes the backside contact of the control relay to open thus deenergizing the power relay and removing the power from the entire system.

Title: Bore machining apparatus
IPC: B24B5/40
Filed: 1979-04-02
Abstract: Bore machining apparatus has a tubular carrier 3 rotatably mounted by bearings 5a, 6a in spiders 5b and 6b within a bore 1 which is to be machined by a pneumatically operated honing or milling unit 19. The unit 19 is carried by a frame 9 which is keyed for rotation with the carrier and is counterbalanced at 26. The frame 9 and unit 19 are displaceable longitudinally relative to the carrier 9 by a lead screw 15 within the bore of the carrier so that when the carrier 9 is rotated by motor 13 and the lead screw 15 is rotated, the unit 19 machines the bore 1 both circumferentially and longitudinally. For machining a small diameter bore 1 the unit 19 can be located partly within the tubular carrier 3 to extend through slot 11 along which it is longitudinally displacable, possibly by draw cable, while the carrier 3 is rotated to effect the circumferential and longitudinal machining of the bore. The machining tool 2D is preferably a honing stone which is pneumatically operated so that it vibrates or oscillates on an air cushion both radially and axially relative to the surface of the bore. <IMAGE>
