Patent GB-2001101-A (GB)
Title: Process and apparatus for the electrodeposition of nickel
IPC: C25D21/18
Filed: 1978-06-27
Abstract: In the electrodeposition of nickel onto articles, a proportion of the nickel electrolyte is continuously removed via conduits 5, 7 from the electrodeposition bath 1, a part of the removed electrolyte is combined with used liquid from the rinsing apparatus 12 (via conduit 18) and passed via conduit 20 through a filter 22 (especially active carbon) for organic decomposition products, and the filtrate is combined in collecting chamber 21 with the remainder of the removed electrolyte via conduit 19. A major proportion of the resulting mixture is returned directly via conduit 23 to the electrodeposition bath. A minor proportion of the mixture is treated in cleaning system 25 to remove metal impurities and then in electrolytic cell 26 to recover excess nickel dissolved in the electrodeposition bath, and is then also returned to the bath via conduit 27. No waste liquid is produced, and evaporation losses are counterbalanced by appropriate control of the introduction of fresh rinsing liquid. <IMAGE>

Title: Method and apparatus for conveying fibrous material
IPC: D01G23/00
Filed: 1978-07-12
Abstract: Fibrous material to be formed into a web is commonly conveyed by conveyor belts or pneumatic means but such methods of conveying are susceptible to breakdown and do not allow for more extensive treatment of the fibrous material. In a method of this invention the material is conveyed by feeding the material onto a table 3 and shaking the table to cause the material to move relative to the table. Apertures 4 may be provided in the table to allow separation of waste from the fibrous material: heavy waste falls through the apertures while light waste such as dust is carried upwards by air blown upwards through the apertures. <IMAGE>

Title: Digital transmission for telephone use
IPC: H04M1/2755
Filed: 1979-10-19
Abstract: In a telephone subscriber's instrument, dialling of a wanted number uses a mark-sensing technique in which relative movement occurs between the wanted number represented in bar code form and a sensor.

Title: Method of manufacturing boards of soft cellular plastics
IPC: B29C70/68
Filed: 1980-04-01
Abstract: A sheet 10 of open-cell, soft cellular plastics e.g. polyurethane or vinyl foam is impregnated with a solution 12 of thermosetting resin, and then the sheet thus impregnated is squeezed e.g. by rollers 20, 22 to remove a substantial amount of the solution from the sheet with the remainder of the solution being uniformly distributed throughout the sheet.

Title: Method and apparatus for self- cleaning drilling mud separator system
IPC: B07B1/54
Filed: 1980-04-03
Abstract: A vibratory separator for separating drill solids from drilling mud after return from the well bore, includes a separator screen (102) and a screen cleaning device (106) positioned adjacent the screen. The screen cleaning device is supported by suitable means (58, 84) to permit filtered mud to pass freely through the device for collection below. The screen is a fine wire mesh mounted to the separator housing in such a manner that it vibrates during operation of the system to keep drilling solids from clogging the wire mesh and restricting the flow of drilling mud. The screen cleaning device serves to support the screen and mud thereon in addition to vibrating and wiping the screen as the device rotates due to the orbital oscillatory vibrations of the system. <IMAGE>

Filed: 1980-06-12
Abstract: A method for the production of dry fodder from fibrous substances, predominantly straw, is disclosed, the method having the purpose of reducing technical equipment requirements, operating costs, and energy and material consumption. Accordingly, process steps of the method are so combined into stages (1, 2, 3, 4, 5) of first and/or second order that several operations can be performed at the same time on one ingredient of the fodder. The kinetic and potential energy in that case fed into the ingredients is at the same time utilized for carrying out the stages, for example for the conveying and mixing, in the production of dry fodder in compact or loose form.   <IMAGE>
Patent GB-2057791-A (GB)
Title: Improvements in electric cable joints and terminations
IPC: H02G15/25
Filed: 1980-08-15
Abstract: Risk that metal particles carried by flowing oil in an oil-filled cable joint or termination will settle along an oil path 15 between a cable conductor 1 and the space 20 bounded by the joint or termination enclosure 12 is substantially reduced by making at least part, and preferably the whole, of the boundary wall of the path of a fibrous insulating material, e.g., paper. Fibres of the boundary wall so formed protrude into the path and restrict mobility of metal particles carried by the flowing oil; some metal particles will penetrate the fibrous insulating material which will also absorb from the oil some types of dissolved contamination, e.g., moisture. The oil path 15 may extend through a body 14 of fibrous insulating material built up around the conductor joint or termination as shown in Fig. 1 or, over at least part of its length, it may be formed between such a body 14 of fibrous insulating material and a preformed body 11 of cast resin. <IMAGE>

Patent GB-2067891-A (GB)
Title: Dishwashing machine
IPC: A47L15/42
Filed: 1981-01-14
Abstract: A dishwashing machine is provided with level regulating means comprising a duct (1) which is connected to the rinsing chamber of the machine, said duct having a wall (2) with overflow edge (3) at the height of normal level (4) in said chamber, an overflow channel (5), a chamber (6) divided by wall (7) to form air traps (8), (9), connected by conduits (10), (13) to level switches (not shown), and a siphon duct (15). In use, when the water level in the rinsing chamber rises above normal level (4), water flows into duct (1) over edge (3) into chamber (6), causing air trapped in trap (8) to actuate a level switch to close a water inlet valve and start up a circulating pump, thereby lowering the water level. If, because of some defect the water level rises with the circulating pump operating, the other level switch is actuated when level (11) is reached to operate an emptying pump, which also removes water from duct (1) via siphon duct (15). <IMAGE>

Title: Hydraulic control system
IPC: F15B13/042
Filed: 1981-04-30
Abstract: An hydraulic control system, particularly for controlling the movements about two axes of the nozzle of a fire fighting monitor. The supplies or working fluid, preferably water, from a source 18 to two double-acting actuators 8, 9 provided for this purpose are controlled by four pilot-operated control valves 13 - 16 fed with hydraulic pressure signals, transmitted through a different fluid, from a remote hand- operated pressure generator 23. The transmission of signal pressures to the control valves may be effected via long lengths of flexible plastics tubing 27A- 27D filled with the signal fluid and in order to avoid problems with the propagation of pressure changes through such tubing due to its inherent elasticity, the range of signal pressures to which each control valve is adapted to respond is selected to be at a relatively high level as compared with the pressure of the working fluid 18. To allow manual shifting of the nozzle, a valve 20 is operated to couple both sides of the vistas together or, for venting, to drain 19. <IMAGE>
