Title: Anticorrosive coated steel pipe
Inventor: KANASASHI TOSHIO
IPC: B32B7/02
Filed: 1986-03-26
Abstract: An anticorrosive coated steel pipe comprises an electroplated copper layer (2) formed on the external surface of the steel pipe (1); and electroplated zinc layer (3) bonded, via a plated nickel or iron layer (4), to the surface of the electroplated copper layer (2); and a baked outer layer or finish (5) formed on the surface of the electroplated zinc layer (3). A chromate layer is optionally provided between the electroplated zinc layer (3) and the baked coating (5). The plated nickel or iron layer (4) interposed between the electroplated copper layer (2) and the electroplated zinc layer (3) completely suppresses mutual diffusion between the two electroplated layers, thereby preventing local blistering, cracking and peeling in the outer layer during baking, and eliminating the possibility of the outer layer peeling off during subsequent bending operations. The value of final products, as well as resistance to corrosion and impact, can thus be greatly enhanced. <IMAGE>

Patent GB-2180418-A (GB)
Title: Fluorescent lamp supply circuit
Inventor: MACFARLANE ALISTAIR ALLAN
IPC: H05B41/24
Filed: 1986-09-10
Abstract: A circuit supplying arrays of fluorescent lamps comprises a mains to D.C. converter 18 the output of which drives at least one power oscillator 39 operating in the kilohertz range. Oscillator 39 drives L-C resonant circuits 40A, 40A, the C-components of which are each connected in parallel with a respective fluorescent lamp. A voltage control circuit controls the voltage across the C component of the resonant circuit and is effective to limit this voltage in the event of the pertaining fluorescent lamp failing. The control circuit may be a comparator (22), (Fig. 2) which monitors the voltage level at the junction of the L and C components of each resonant circuit and compares this against a reference level. The output of the comparator activates a circuit (21) which inhibits operation of the corresponding oscillator when a fluorescent lamp fails. Alternatively, the Q-factor of the resonant circuit may be reduced by a series- connected PTC resistor (44), (Fig. 4), or the resonant circuit may be detuned by various neons, such as a detuning capacitor (46) associated with a varistor or NTC resistor (45), (Fig. 5), clamping diodes (43) associated with a triac or detuning capacitor (47), (Fig. 6), a triac (48) connected across the C-component, (Fig. 7), or a magnetic amplifier in series with or forming part of the L-component. The lamp array may be in a UV sun bed or a refrigeration cabinet. <IMAGE>

Title: Production of porous elongate moulded bodies from fluorine-containing polymers
Inventor: EILENTROPP HEINZ
IPC: H01B19/02
Filed: 1987-02-20
Abstract: In the production of such bodies, moulded bodies produced by paste extrusion are freed by drying, in a first step of a continuous process, from the lubricating or parting agent used in their production and, in a second step, are stretched and the polymer material simultaneously sintered at a temperature at least equal to the crystallite melting temperature of the polymer. Stretching may be effected in the output direction and/or transversely thereto. The moulded bodies, e.g. tapes or foils, have properties making them suitable for use in the construction of elongate products, such as electric cables and leads, tube assembly cables and pipelines.

Title: Pyramid game
Inventor: PAGE MARK STEPHEN
IPC: A63F3/02
Filed: 1989-02-28
Abstract: The Pyramid on which the Pyramid Game is played, is made up of three or four equal sides (not including the base). The Pyramid is split into steps, from the base to the summit. On each step there is a symmetrical or patterned hole formation. The number of holes in the formation decreases from the base plateau to the summit, where there is only one hole. Where two faces of the Pyramid meet, every alternate step is marked with a ruled line which, in effect, restricts the movement of any person's game piece moving from one face onto another on that particular plateau, layer or step. <IMAGE>

Patent GB-2223146-A (GB)
Title: Radio transceiver capable of avoiding intermodulation distortion
Inventor: KASAI YOSHIHIKO
IPC: H04W88/02
Filed: 1989-08-15
Abstract: A radio transceiver comprises an RF amplifier 13 and a first frequency mixer 15 which converts and amplified RF signal into a first IF signal and whose output may include intermodulation distortion. A second frequency mixer 19 converts the output of first frequency mixer into a second IF signal. An interference detector 28 detects the intermodulation distortion by seeing if a beat is included in the second IF signal. Upon detection of intermodulation distortion, a controller 29 minimizes the gain of RF amplifier to decrease or eliminate the intermodulation distortion. Responsive to the end of conversation (hook switch 41) the controller maximizes the gain of RF amplifier to increase the reception sensitivity. The controller may periodically maximise the RF amplifier gain after the detection of the intermodulation distortion. If no intermodulation distortion is detected during this gain-maximized period, the controller keeps the gain to be a maximized value. If the intermodulation distortion is not decreased or eliminated even though the RF amplifier gain is minimized, the controller may change frequency used for communication. <IMAGE>

Patent GB-2238744-A (GB)
Title: Fastener extracting tool
Inventor: TURNER MICHAEL JOHN
IPC: B25B23/00
Filed: 1989-10-24
Abstract: The tool has a bar 11 and a screwed-on adaptor 14 carrying an appropriately sized anchor bolt 54. The anchor bolt 54 is screwed into a free bore adjacent to a jammed screw. A block 12 is slid along the bar 11 until the driver bit 60 carried thereby is directly ever the jammed screw. In this position the free end 21 of the lever bar 11 is axially farther from the bit 60 than the bit is from the anchor bolt 54. By pressing down hard on the free end 21 to engage the bit 60 in the head of the jammed screw and with the aid of a ratchet spanner, the bit assembly 15 can be turned to loosen and remove the jammed screw. <IMAGE>

Title: Method for the preparation of a two-tone coloured metal-made personal ornament
Inventor: TAGAWA HIROSHI
IPC: C23C28/00
Filed: 1989-11-21
Abstract: In a method for the preparation of two-tone coloured metal-made personal ornaments such as spectacle frames, watch cases or tiepins having areas of a pinkish golden colour and areas of a different, e.g. black, colour, an organic masking layer is formed patternwise on the surface of a layer of a ternary alloy of gold, nickel and copper and colouring of the surface is effected on the unmasked areas followed by removal of the organic masking layer with a remover solution. The coloured top coating layer may be formed by ion plating by reactive deposition of ionized titanium metal with ionized molecules of oxygen and carbon dioxide. As compared with the conventional method using a gold-palladium binary alloy instead of the above-mentioned gold-nickel-copper ternary alloy, a great improvement can be obtained in the efficiency of the removal of the masking layer with a remover solution. The undercoating may be a carbide, nitride or carbonitride of a metal selected from titanium, zirconium, hafnium, vanadium, tantalum and chromium.

Title: Preparation of polymer latices
Inventor: PURBRICK MALCOLM DONALD
IPC: C08F2/24
Filed: 1990-06-21
Abstract: It is known to use polymer latices of known particle size as standards in particle size measuring techniques. However, most latices used in such measurement techniques are monodisperse and as a consequence are of limited use. Described herein is a method for the preparation of polymer latices having broad particle size distributions which are suitable as standards in particle sizing techniques. The method uses a semi-continuous emulsion polymerisation technique in which a surfactant, an initiator and a monomer are reacted together, characterised in that the surfactant concentration is substantially and uniformly increased throughout the reaction.
