Patent GB-2024039-A (GB)
Title: Clarifier and method
IPC: C02F1/463
Filed: 1978-06-29
Abstract: A fluid, such as air or water, carrying suspended solids is directed between a pair of oppositely charged, corrugated surfaces in order to subject the flow to an undulating action that increases the frequency with which the solid particles impinge against one another, thereby increasing the rate of flocculation of the solids. In the case of airborne particles, the corrugated surfaces are arranged upright so that the flocculated particles attracted to one or the other of such surfaces gravitate therefrom into a conveying mechanism that delivers such particles to a collecting receptacle. In the case of liquid-borne particles the flow is forced to travel upwardly after passing between the surfaces, thereby encouraging the flocculated particles to settle out into a sump that is associated with the uphill flow passage. In each case, two sets of charged surfaces may act in series, the first having at least one of its surfaces insulated from the flow for electrostatic action only, while the second has neither surfaces so insulated for electrolytic action.

Title: Optical apparatus for directing a light beam of variable angle of incidence along a fixed path
Inventor: NICHOLAS JOHN FREDERICK
IPC: G02B7/182
Filed: 1978-09-21
Abstract: An optical apparatus e.g. a sight unit, adapted to receive a light beam whose angle of incidence can vary and to direct the beam along a fixed path has a cradle 5 mounted for angular adjustment about a fixed axis D, a carriage 7 on the cradle 5, a mirror 6 mounted on the carriage 7 and a cam control mechanism (Figure 3, not shown) to effect controlled movement of the carriage 7 relative to the cradle 5 during angular movement of the cradle about the fixed axis D. The apparatus is particularly useful when two light beams from different sources have to be directed along respective parallel predetermined optical axes O1, O2, for example, a first collimated light beam from a distant scene or object and a second collimated light beam carrying the image of a graticule or reticle contained in a projection unit 17. In such a case two mirrors 2, 6 are provided each mounted on a cradle 3, 5 connected to one another by a linkage mechanism 4 so that the arrangement provides a parallelogram linkage A, B, C, D. A third mirror 18 angularly adjustable about a fixed axis E receives the second light beam and reflects it towards the mirror 6. <IMAGE>

Title: A method of polarizing a thermoplastic resin film
IPC: H01L41/45
Filed: 1978-10-17
Abstract: A method of polarizing a thermoplastic resin film 1 between a pair of electrodes 2, 2' comprises the steps of placing a layer of a dielectric or semiconductor material 3 whose electrical conductivity is higher than that of the thermoplastic resin film 1 between at least one of the two electrodes 2, 2' and the thermoplastic resin film 1, and applying a high voltage to the electrodes 2, 2'. Layer 3 limits the current flow through a defective area 4 of film 1, so preventing or reducing dielectric breakdown in area 4.

Title: Polyphase motors
IPC: H02K3/28
Filed: 1979-02-19
Abstract: An alternating current dynamoelectric machine includes a plurality of phase windings placed in stator core slots with certain slots shared by more than one phase winding and a number of those shared slots having one phase winding portion disposed in the bottom part of the slot and a portion of another phase winding disposed in the upper part of the slot near the stator bore. This another phase winding comprises a greater number of turns of a smaller diameter wire as compared to the one phase winding. In one exemplary embodiment a three phase machine has concentric windings with the third phase wound with the same number of turns as the other two phases but with each turn comprising a bifilar or two strand turn of a lesser diameter wire. This arrangement lowers the injection forces required for placing the third phase in the stator core and also aids forming the third phase windings about a temperature sensor. All three phases may be wound of wire of similar materials.

Title: Removing residual moisture from adsorbers
IPC: B01D53/02
Filed: 1979-03-05
Abstract: A wet adsorbent bed 5, resulting from steam desorbing of a component adsorbed from a process gas stream P, is dried by driving a drying medium, T, e.g. air, through the adsorbent in the same direction as the process stream and, during a first drying phase or interval, removing the resulting wet medium through an auxiliary first outlet 19 and, during a second phase or interval after the moisture content has been reduced, removing the medium through a second main outlet 18. Outlet 19 may discharge the first phase drying medium to a workroom A via a condenser 26, and may also function to remove condensate K, the condensate being passed through a mud filter 22 which is intermittently flushed with condensate collecting in chamber 3 below the adsorbent bed. Outlet 18 may supply the treated process gas and the second phase drying medium directly to the workroom. <IMAGE>

Patent GB-2054101-A (GB)
Title: Differential pressure valve
IPC: F01M1/20
Filed: 1979-07-17
Abstract: The valve is associated with, for example, an oil pump for a refrigeration compressor, and senses whether the pump is delivering a desired minimum pressure. The valve has inlet and outlet ports 1a and 2 in communication with inlet and discharge sides of the pump respectively. A valve member 3 is biassed by a spring 5 into contact with the inlet port 1a and blocks it. When the pump is delivering fluid at a first predetermined pressure drop across the pump, the valve member 3 is moved from its seat. A bleed flow now passes the valve member 3 passage 4 or by virtue of a slight clearance it has in the valve chamber 10. This flow impinges on a self heating thermistor, which is thus cooled to a temperature which indicates whether the required pressure difference is being supplied. When the pressure difference approaches a second, excessive, value, the valve member 3 uncovers a pressure relief outlet port. and the pressure difference cannot build up further. If desired, the sensor 7 can also respond to the temperature of the fluid being pumped. <IMAGE>

Title: Improvements in and relating to ventilation and cleaning of looms
IPC: D03J1/00
Filed: 1979-07-17
Abstract: In a loom having provision for ventilation, the rate or direction or temperature or humidity of the air flow through a ventilation duct (17, 30) is controlled by a programmer (41). This makes it possible to operate on a weak flow of, for example, extraction air during normal weaving, with a correspondingly low electricity consumption by the motor driving the or each fan, the weak flow being supplemented intermittently (for instance, once or twice daily) by a short intense flow of suction air to clean the machine thoroughly, more particularly of the relatively heavy lint deposited on parts of the loom during weak flow operation. Air extraction is indicated at 28, 28b. Alternatively air may be injected as indicated at 28a or may be alternately extracted and injected. <IMAGE>

Title: Process for preparing fish products and product of the process
IPC: A23L17/00
Filed: 1979-09-10
Abstract: A method of producing a fish product using minced or shredded fish which would otherwise be un- suitable for human consumption. The fish is formed into a sheet 26 by rollers 22 after removal of bones, skin and other non-edible fractions at stage 12. One surface of the sheet 26 is then cooked on drum drier 24, cooking being terminated before the sheet is cooked right through. The sheet 26 is cut into pieces 34 which are stacked to form a block with cooked and uncooked surfaces in contact. Such surfaces do not merge and thus a layered effect is obtained. The block is subsequently frozen under pressure. Thereafter the block can be cut and crumbed to form fish fingers or cut and shaped so as to have the appearance of fish fillets. The flaky texture of the resulting product, due to its layered composition, simulates non-processed fish. <IMAGE>

Filed: 1979-11-29
Abstract: An easily dispersible deeply colored pigmentary form of copper phthalocyanine (CuPc) is obtained from crude CuPc, when the crude CuPc is milled in the absence of assistants but in the presence of from 0.5 to 15% by weight of one or more acids which have a pK of <4.9 and are non-oxidizing under the milling conditions, until a milled material is obtained in which the primary particles haves size of up to 0.1 mu m, and the milled material is then converted to the pigmentary form by heating in water in the presence of from 3 to 30% by weight of a surfactant. On isolating the product, a CuPc pigment is obtained which gives very deep colorations and is very easily dispersible in surface coatings, printing inks and plastics.
