Abstract: 1,165,878. Fuel cell. BROWN, BOVERI & CO. Ltd. 15 March, 1968 [18 March, 1967], No. 12679/68. Heading H1B. A fuel cell, Fig. 2, comprises a plate, 4, of solid electrolyte having electrodes, 4a, 4b,formed on its faces, an annular gasket, 3, of asbestos felt surrounding and spaced from the edge of the plate, an annular member, 2a, 2b, of asbestos felt impregnated with an electrical conductor on each side of the gasket and in electrical contact with each electrode and a metal plate 1a and 1 or 1b adjacent each annular member so that the metal plate, annular and electrolyte plate form a gas space. In Fig. 2 the electrodes are plasma sprayed coatings of silver and nickel and the electrical conductor in the annular members is silver. The components may have holes, 15, for bolting them together, the bolts being surrounded with ceramic sleeves. They may also include bores, 11a-14a, and conduits, 11b-14b, for supplying the gases. A stack of such cells may be joined in series to form a battery, e.g. by using a common metal plate, 1, between 2 cells.

Abstract: 1,193,904. Polymer metal complexes. CESKOSLOVENSKA AKADEMIE VED. 24 May, 1968 [25 May, 1967], No. 24837/68. Heading C3P. [Also in Division G2] A polymer-metal complex is formed by contacting a polymer system containing nitrile groups and groups capable of forming the anions -OSO- 2 , -OSO- 3  or -OPO<SP>2-</SP> 3  in ionizing media. both groups being attached to macromolecular main chains, with silver or copper cations. The ionizing media may be water. The groups may be borne by the same or different macromolecules. The polymer system is preferably a copolymer of acrylonitrile with vinyl sulphonic acid, styrene sulphonic acid or an alkali metal salt of one of these acids. The complex metal cation may be reduced thus forming a dispersion of the free metal in the copolymer. The free metal may be reconstituted by contacting the copolymer with silver or cuprous cations. The copolymer complex containing silver cations may be treated with a halide solution, and this polymer system containing dispersed silver halide may be contacted with silver or cuprous cations. In the examples, acrylonitrile, sodium vinyl sulphonate and optionally ethylene glycol bis-methacrylate or acrylamide, are co-polymerized using a catalyst comprising potassium pyrosulphite and ammonium persulphate with a copper sulphate activator. The polymer is formed into a membrane layer or filament which is treated with silver nitrate or acetate solutions or a solution containing cuprous ions. In other examples silver nitrate is added to polyethylene- or polystyrene-sulphonic acid and this is mixed with polyacrylonitrile; alternatively the two polymers are mixed and together added to a silver nitrate solution. In, a further example, a nitric acid solution of polyacryonitrile is treated with silver nitrate and then reacted with an acrylonitrile-ethylenesulphonic acid copolymer.

Abstract: 1,041,368. Thermal switches. IDEAL CORPORATION. March 17, 1964 [April 25, 1963], No. 11207/64. Heading H2B. A thermal switch comprises a resilient vane 14 which is welded to a mounting member, at 42, and a thermally expansible pull member, comprising a resistive strip 20, which, when cold, causes the vane 14 to bow with its concave side towards it, so as to close contacts 46, 48. When the strip 20 is heated by current passing from terminal 28 through strip 20, plate 14, contacts 46, 48 to terminal 32, it expands and allows vane 14 to return to its natural setting wherein it is bowed in the opposite direction, whereupon the contacts 46, 48 are separated. The strip 20 then cools and draws the vane 14 back to its original position. The vane 14 has a slot 12 therein to provide a side strip 16 which is crimped to provide a means of adjusting the operating characteristics of the vane.

Title: Cellulase-producing microorganism
Inventor: GALLO B
IPC: C12N1/20
Filed: 1979-11-16
Abstract: A process and a microorganism for synthesizing cellulase enzymes are described. The microorganism is a mutant strain of an Ascomycete fungus capable of synthesizing cellulases. The synthesis of cellulases by the mutant is nonrepressed by glycerol, repressed by glucose but not subject to postrepression lag, and inducible to high levels by lactose. Furthermore, the combination of lactose with xylose elicits maximum cellulase synthesis by the mutant.

Title: Sail batten
Inventor: PARMENTIER JAN ANTON
IPC: B63H9/06
Filed: 1983-02-15
Abstract: A batten which is made of a plastic profile, that seen on a transverse sectional view, consists of several cavities next to one another, in order to hold close fitting inserts. In this manner it can be obtained that the stiffness of the batten is changing gradually, because the reinforcing inserts in the cavities have a different length. The stiffness of the batten can be changed in a simple way and right along its full length. The profile and rod-like inserts are substantially constant in cross-sectional dimension throughout their length and consequently easy and cheap to manufacture.

Patent ZA-895153-B (ZA)
Title: Laminated copper assembly
Inventor: PATON CHARLES RICHARD
IPC: H01H9/38
Filed: 1989-07-06
Abstract: A laminated contact assembly for a circuit breaker with each individual contact assembly having a contact arm portion, carrying a movable main or arching contact and a stationary conductor portion. A flexible shunt connects the contact arm portion to the stationary conductor portion. Intermediate individual contact assemblies are provided with T-shaped slots for receiving square-headed fasteners. This avoids the need to drill and tap holes in the laminated contact arm assembly. Since the individual contact arm assemblies are fastened together, the square-headed fasteners disposed in T-shaped slots in intermediate individual contact arm assemblies is greatly reduced. The flexible shunt is wound from a continuous strip of an electrical conductor.

Title: Communications apparatus and method of communicating timing information
Inventor: JONES EMMA LEIGH
IPC: H04L29/08
Filed: 2000-08-14
Granted: 2004-05-19
Abstract: In communication systems requiring timing data, it is sometimes desirable to provide such timing data over an asynchronous medium, for example, Ethernet. However, it is understood that such timing data cannot be transmitted via the Ethernet. The present invention provides a mechanism for inserting timing information in an inter-frame gap (502) of a data frame (500) of the Ethernet. Consequently, it is possible to transmit timing information via the Ethernet. The provision of timing data in the inter-frame gap (502) obviates the need for a dedicated connection between network entities (206, 208) coupled to the Ethernet.

Subsequent operation of the rotaray actuator (19) and re-energisation of the electromagnetic device (2, 3) re-sets the ventilator for automatic operation. Instead of a rotary actuator (19) a linear actuator (20) may be used.
