Patent GB-2186769-A (GB)
Title: Conductive glass plate
Inventor: HASEGAWA JUN
IPC: C03C27/12
Filed: 1986-12-23
Abstract: A glass plate 31 has a transparent conductive film 32 on one face. A current is not supplied to the entire surface of a transparent conductive film 32 but limited by slits 34 in the film 32, so that the current is supplied along a limited current path. By attaining a predetermined current density only in a predetermined portion of the transparent conductive film, even if power consumption per unit time is small, thawing, defrosting or the like in the predetermined portion can be immediately performed. Bus bars 33a, 33b, 33c and 33d serve as terminals for voltage applied to the film 32. The pattern of current flow can be altered by altering the respective polarities of the bus bars 33. Slits 34 may be formed which completely surround areas of the film 32 which are then only heated by conduction. <IMAGE>
Patent GB-2202999-A (GB)
Title: Electrical contacts adhered together
Inventor: MARRIAGE JOHN
IPC: H05K3/32
Filed: 1987-03-25
Abstract: An electrical contact has a contact surface formed by a porous electrically conducting material, such as sintered bronze or brass. The pores of the electrically conducting material are filled with an adhesive material. When the electrical contact is placed in engagement with another similar electrical contact no initial adhesion takes place but a permanent adhesive bond between the contact surfaces forms or is formed after a period of time, with attendant electrical interconnection between the electrical contacts. The invention enables circuit board edge connections to be repeatedly made during assembly and test, after which the adhesive is activated to make a permanent electrically conducting bond between the contact surfaces.

Patent GB-2208559-A (GB)
Title: Liquid crystal devices
Inventor: BOWRY CAROLYN
IPC: G09G3/36
Filed: 1987-08-12
Abstract: In a method of driving a matrix of ferroelectric liquid crystal devices in a TDM mode, each strobing signal comprises first and second pulses (20, 21) of opposite polarities and of different amplitudes, together with a dc voltage (26) which is applied from the end of the second pulse to the beginning of the first pulse of the next strobing signal on the same strobe line to cancel the dc level which would be caused by the unequal pulses. Data ON signals applied selectively to data lines of the matrix comprise two consecutive pulses (22, 23) of opposite polarities. Data OFF signals (24, 25) may be the inverse of the data ON signals or may comprise a constant dc level. The combination of the two pulses with a dc level to form each strobing signal means that only two strobe pulse time slots per frame are required for addressing each strobe line, as compared with the conventional systems in which four time slots per frame are required.

Patent GB-2198750-A (GB)
Title: Controlling electroless deposition
Inventor: HUGHES ROWAN
IPC: C23C18/16
Filed: 1987-10-29
Abstract: Electroless metal plating solutions are formulated and controlled to provide high quality metal deposits by establishing the ratio of its intrinsic anodic reaction rate to its intrinsic cathodic reaction rate to be less than 1.1. By the "intrinsic anodic reaction rate" is meant the anodic reaction rate, i.e. the rate of oxidation of the reducing agent measured on a metallic surface in an electroless deposition solution, by imposing a potential slightly more positive than the mixed potential on the metallic surface, and by "intrinsic cathodic reaction rate" is meant the cathodic reaction rate, i.e. the rate of reduction of metallic ions to metal measured on a metallic surface in an electroless deposition solution, by imposing a potential slightly more negative than the mixed potential on the metallic surface. The "mixed potential" is also defined. Methods are provided to formulate electroless copper plating solutions which can deposit copper on printed wiring boards of quality sufficient to pass a thermal stress of 10 seconds contact with molten solder at 288 DEG C without cracking the copper deposits on the surface of the printed wiring boards or in the holes. The ratio of the intrinsic anodic to the intrinsic cathodic reaction rates can be determined by electrochemical measurements on the deposition solution of which specific details are given, or it can be estimated by varying the concentration of the reactants and measuring the plating rates, suitably by gravimetric determinations. The electrochemical measurements involve providing a test electrode, an auxiliary electrode and a reference electrode in the plating solution and then measuring the two reaction rates. For electrolessly depositing copper according to this reaction the plating reaction must be under anodic control which means the plating rate depends on the concentration of the anodic reactants, the concentration of the anodic reactants, the concentration of the reducing agents for the metal ions, or depolarizers for the half reaction involving the reducing agents. In order to maintain the desired rates it may be necessary to increase the rate of the intrinsic cathodic reaction or to decrease the rate of the intrinsic cathodic reaction. The rate of the intrinsic cathodic reaction may be increased by raising the concentration of the metal ion; adding catalyst or a depolarizer to accelerate the cathodic reaction; or by increasing the surface area available for the cathodic reaction. The intrinsic anodic reaction rate may be decreased by decreasing the concentration of the anodic reactants (i.e. lower formaldehyde or lower PH); or decreasing the concentration of anodic depolarizers.

Title: Attachment apparatus for a tyre mat
Inventor: ELLIS REGINALD CHARLES LINWOOD
IPC: B60C27/10
Filed: 1988-07-05
Abstract: In order to attach a tyre mat to the circumference of a tyred wheel, a front flexible elongate member (22) is slidingly passed through attachment fittings (16) on the mat (13) spaced around the periphery of the front side of the wheel (10), and a rear flexible elongate member (23) is slidingly passed through attachment fittings (16) on the mat (13) spaced around the periphery of the rear side of the wheel (10). Respective sliding attachment members (29, 24) are then used to attach parts of each elongate member (27 or 23) together so as to enable relative sliding movement between the parts and so as to cause the elongate member (27 or 23) to form an intermediate loop portion which extends through the attachment fittings (16) on the associated side of the wheel and a further portion outside the loop portion. The further portion of the rear elongate member (23) is passed across the circumference of the wheel (10) to the front side of the wheel by way of a guide piece 19, and finally a tensioning device (26) is connected at the front side of the wheel to the further portions of both elongate members (27, 23) and operated so as to tension the loop portions of both elongate members (27, 23) to draw the attachment fittings (16) radially inwardly of the wheel (10) and to thereby secure the mat (13) firmly on the circumference of the wheel.

Title: A method for recovering styrene monomer from discarded polystyrene scrap through pyrolytic reduction
Inventor: LUO XINMIN
IPC: C07C4/22
Filed: 1990-02-13
Abstract: A method for recovering styrene monomer from discarded polystyrene scrap comprises pyrolytic reduction. The method involves the use of metal oxide catalyst and an alloy additive in the pyrolyzer. When the temperature of the pyrolyzer reaches 250 DEG C, the discarded polystyrene granules 3-5 mm in diameter are continuously fed into the pyrolyzer e.g. at a rate of 0.15 - 0.20 kg/min. At the temperature of 350 DEG C gas is introduced. The temperature is kept in a range of 450-500 DEG C to pyrolyze the polystyrene. During feeding of the polystyrene a reduced pressure distillation is carried out. The yield of a liquid distillate is 90% of the feed stock in weight. The recovery rate of styrene amounts to 70-75%. The present invention provides an effective method for solving environmental pollution caused by discarded polystyrene.
