Patent GB-2063920-A (GB)
Title: Decorative anodised films on substrates
IPC: C25D11/26
Filed: 1980-11-18
Abstract: The films are produced by depositing an anodisable coating (e.g. Ta, Ti, Zr, alloys thereof and nitrides) onto a substrate (e.g. stainless and mild steel) by sputter ion plating followed by anodising at a controlled voltage in order to control oxide film thickness and hence colour. Anodising is known to generate a thin film on an anodisable material. A particular film thickness may generate a distinctive interference colour if the oxide has a high refractive index. However, not all materials are anodisable and this technique enables the properties of anodisable films to be made more generally available.
Patent GB-2088811-A (GB)
Title: Producing a succession of individual, e.g. multi-tube, packs
IPC: B65B9/067
Filed: 1980-11-28
Abstract: In a horizontal form-fill-seal machine, twin-tube packs, for example, can be produced by forming in a moving flexible web (11) two corrugations running in the direction of movement of the web; bringing the opposite edge regions of the web (11) towards one another beneath the corrugations and folding the edge regions against one another to form a fin projecting beneath the centreline of the web; gripping the fin between pairs of contra-rotating rollers which drive it in the direction of movement of the web and which crimp the fin to seal it; sealing the web surfaces between the corrugations together to define twin tubes in the web; and cross-sealing and severing the web at intervals spaced along its length. The two thicknesses of material between the currugations are sealed by nipping them between a heated sealing roller and the face or faces of one or a pair of the contra-rotating rollers which are themselves heated to seal the fin as it passes through their nip. The web may be perforated or separated longitudinally between twin tubes. <IMAGE>

Title: Treatment of polyamides to improve antistatic, hygroscopic and dye receptive properties
IPC: D06M101/16
Filed: 1981-02-16
Abstract: Solid high molecular weight polyamides, particularly shaped structures such as fibres, filaments or knitted fabrics, are modified to improve their properties such as electrical conductivity, water absorbency and dye receptivity of the polymer, while retaining the essential structural shape. The polyamide is heated in the presence of an aqueous treating solution containing an ethylenically-unsaturated monomer which is a source of carbene radicals, but does not readily polymerize under the conditions of treatment, and a catalyst which is a source of hydrogen ions or protons. The treatment is carried out at a temperature and for a sufficient time so as to effect essentially single molecule additions of the monomer to the polymer chains with substantially no graft polymerization of the monomer to the polyamide.

Patent GB-2081942-A (GB)
Title: Controlling direct current in inductive loads
IPC: H02P7/29
Filed: 1981-05-07
Abstract: Electric power is applied directly to the inductive load (L, RL) through a switch (SW1) which closes the circuit to apply charging current to the inductive load for fixed periods of time. A discharge path (RS, D1) is provided for the inductive load when the switch opens the charging circuit. The discharge current is monitored by controller (20), and when the voltage it produces across resistor RS (VS) decays to a selected value (VR), the switch is again closed for the fixed charge time. By this means the current controller achieves high efficiency. The load may be a D.C. motor, solenoid or a similar device. The reference voltage (VR) may be set by a motor speed regulator feedback load. <IMAGE>

Patent GB-2095705-A (GB)
Title: Clothes washing machine drive
IPC: D06F34/10
Filed: 1982-03-22
Abstract: A drive for a clothes washing machine to give agitating and spin modes uses a reversible motor 15 connected through a speed reducing transmission means to an agitator 7 so that, in the agitating mode, cyclic reversing of the motor order control of an electronic circuit causes cyclic reversal of rotation of the agitator and, in the spin mode, rotation of the motor 15 in one direction causes lost motion in a lost motion device 20, 21, 22 between the agitator 7 and a spin bowl 2 to be taken up and the bowl is then spun to remove water from clothes in the bowl. The lost motion device between a pulley 12, on the agitator spindle 8, and the shaft 3, on which the bowl 2 is mounted, comprises a pin 20 carrying a rubber buffer 21 which "engages" an arm 22 on the shaft 3 so that, in the agitating mode, the pin 20 can rotate close to one revolution without moving the arm 22 but, in the spin mode, the pin 20 carries the arm 22 and thus the bowl 2 around with the shaft 8. The lost motion arrangement can be repeated as desired for agitation through more than one revolution. <IMAGE>

Abstract: Apparatus is provided for manoeuvring a ship having a Z-type propellor structure. The propellor structure has a propellor shaft powered, via a clutch 39, by a main engine 40. The apparatus has a handle 4, a synchro 22 and a potentiometer 26. The synchro 22 detects rotation of the handle 4 about its own axis, and transmits a signal S1 dependent upon the angle detected. The potentiometer 26 detects the angle through which the handle 4 pivots, and transmits a signal S3 dependent upon the pivotal angle detected. The signal S1 and S3 pass to a control device 32. 0n receiving the signal S1, the control device 32 transmits a control signal S2 to a rotary drive 33 which pivots the propellor shaft 35, and so effects steering. Depending on the magnitude of the second signal S3, the control device 32 transmits either a second control signal S4 or a third control signal S5. The second control signal S4 is transmitted to slippage control means 36, 37, 38 associated with the clutch 39, and the third control signal S5 is used to control the speed of the main engine 40 via a governor motor 41. <IMAGE>
