Title: Windshield antenna system
IPC: H01Q1/50
Filed: 1970-07-24
Abstract: 1276057 Windscreen aerial FORD MOTOR CO Ltd 24 July 1970 [11 Aug 1969] 35915/70 Heading B5N [Also in Division H4] A windshield aerial system 10 comprises first and second glass sheets 12, 14 which are laminated together with a polyvinyl butyral interlayer 16. Two fine aerial wires 20, 20, which are adhered to said interlayer before lamination, extend upwardly from the centre of the base of the windshield to near its upper edge, whence they continue parallel to said edge in opposite directions. The wires are exposed in a cut-out portion 18 of the lower edge of the glass sheet 14. A conductive terminal plate 24 is located in the portion 18 by legs 26, 26 so that there is a space 28 between its edge and the edge of said portion 18. Alternatively, the space 28 may be provided by means of a central projection from the plate 24, positioned between the wires 20, 20. A rear lug 30 of the plate 24 is bent over on assembly, and the two aerial wires and an exposed end 34 of an insulated cable 32 are soldered thereto. The cable 32 is bent round, is passed through a passageway 44 in a front portion 42 of a non- conductive tab 38, and is terminated in a connector 36. The tab 38, which may be made of acrylonitrile-butadiene-styrene copolymer (ABS plastic) is fixed to the windshield by means of a pressure-sensitive adhesive layer 40 which is placed on a portion extending below the glass sheet 12. The front portion 42 is continued by a flat portion 46, and the two portions, which define a rear surface 48 abutting the edge of the glass sheet 12, provide protection for the joint on the lug 30. The cut-out portion 18 is finally filled with sealing compound 50, such as a potting compound formed from a silicone rubber base adhesive.

Filed: 1976-08-27
Abstract: 1524254 Vacuum cleaners GOBLIN (BVC) Ltd 27 Aug 1976 [1 Sept 1975] 36006/75 Heading A4F A vacuum cleaner comprises a drum 2 having a cap 22 supporting a motor assembly 23 for driving an impeller to create a vacuum within the drum, a cleaning head 25 coupled to an inlet near the base of the drum, and a conduit 29 leading from the inlet and whose free end is positioned or positionable above the level of the inlet. The conduit 29 may as shown be a flexible hose having an elbow 30 at its free end which can be releasably secured to a support 36 at the top of the drum so that when sucking in liquid waste, liquid is directed tangentially of the drum wall to produce a cyclone effect. The drum can be drained of liquid by releasing the elbow 30 and dropping it to the bottom of the drum to allow the liquid to drain through the inlet. For solid waste the elbow 30 is positioned at the bottom of the drum with a dust bag attached. Instead of a flexible hose, the inlet may communicate with a valve which can connect the inlet either with an upwardly extending rigid conduit or directly with the interior of the drum. A filter 40 is used to protect the motor assembly 23, and a sensor 42 may be provided to stop operation of the cleaner should the level of liquid in the drum become too high. The cleaning head 25 is coupled to a socket 24 attached to the inlet, the head being coupled by a bayonet coupling which allows the head to be rotated 180 degrees from the illustrated operative position to an inoperative position. The drum 2 is mounted on a trolley 3 having rubber members 16, which can absorb shocks, and wheels 6, 13. The wheels 13 are castors which are adjustable for height.

Abstract: 155,783. Pintsch Akt.-Ges., J. Dec. 12, 1917, [Convention date]. Vacuum tubes.-Lamps of the type described in Specification 135,485, containing rare gases through which a luminous discharge is passed, are provided with a small addition of common gases or vapours to diminish pulverisation of the electrodes. The addition may consist of hydrogen, oxygen, or nitrogen or mixtures thereof, ammonia, carbonic acid gas, or vaporized metals or metal compounds. It may be introduced at the same time as the rare gas or may be previously occluded in the electrodes or other parts. There should be sufficient common gas or vapour present to be effective even after partial absorption by the electrodes has taken place. A suitable lamp filling consists of neon together with one-quarter of its volume of helium and 1 to 2 per cent of a common gas, preferably hydrogen. When mercury vapour is used as the addition, some common gas should be added to enable the lamp to work at low temperatures; this may consist of not more than 3 per cent, and preferably about 1 per cent of hydrogen.

Filed: 1928-12-06
Abstract: 326,231. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Dec. 6, 1928. Complex metallic compounds of aliphatic oxycarboxylic acids.-Complex metallic compounds of aliphatic oxy-carboxylic acids with metals (including arsenic and antimony) capable of conversion to a higher stage of oxidation are subjected, usually in solution, to the action of oxydizing agents, such as hydrogen peroxide, magnesium peroxide or oxygen itself. The products, which may be neutralized with an alkali or other base, e.g. diethylamine, are useful therapeutically. The starting materials are prepared by treating the alkali salts of aliphatic oxy-carboxylic acids in aqueous or aqueous-alcoholic solution with the oxides or hydroxides of metals which can be transformed into a higher stage of oxidation; if the product be acidic, it may be rendered neutral by means of alkali or amines prior to isolation. Examples are given of the oxidation with hydrogen peroxide of antimony potassium tartrate, potassium stannic tartrate, neutral sodium tervalentantimony gluconate and the acid diethylamine tervalent-antimony salt of mucic acid in aqueous solution. Other oxy-carboxylic acids mentioned are citric and lactic acids. Specification 313,541 is referred to.

Abstract: 1,059,029. Measuring linear displacement electrically. ROLLS-ROYCE Ltd. June 16, 1964 [Sept. 25, 1963], No. 37666/63. Heading G1N. Displacement of a member 16, Fig. 2, moves a metal rod, the middle portion 17c of which is of a different metal from its outer portions 17a, 17e, thus varying the inductances of two coils 18, 19 situated at the junctions 17b, 17d between the metal portions, and unbalancing a bridge circuit 11, the unbalance signal being amplified and rectified in an amplifier and phase sensitive detector 12, and fed via a phase-advance circuit 13 to a motor 14. The motor rotates a threaded rod 20 and thus raises a collar 21, carrying the assembly of coils 18, 19 to rebalance the bridge. The motor also operates an indicator 20a. In measuring the position of a machine tool head two additional bridge outputs from resistors (5, 6) and (7, 8), Fig. 4 (not shown), are respectively arranged to pass through zero as the bridge unbalance voltage approaches zero from a positive or a negative direction, and these outputs control a clutch (24a) which automatically disengages or partially disengages the motor (14) from the lead screw to allow the final part of the bridge rebalancing to be completed slowly and/or manually. The clutch control circuits are transistorized Schmitt trigger circuits, Fig. 5 (not shown), and each receives an input from the phase advance circuit 26 to ensure that if the tool is moving fast the approach signal is given correspondingly earlier. Backlash in the mechanical part of the system is removed by the use of two equally and oppositely exited motors Fig. 7 (not shown), the bridge unbalance signal causing an increase or decrease in the excitation of one of the motors.
