Patent GB-2066565-A (GB)
Title: Structured solar cell and method of making same
IPC: H01L31/0236
Filed: 1979-12-28
Abstract: A silicon solar energy cell having improved anti-reflective properties and resistance to radiation has a light receiving surface having spaced indentations in the form of inverted pyramids therein. The pyramids, which have their bases in the plane of the light-receiving surface, are produced by masking the surface with a layer resistant to attack by a silicon etchant, forming open regions in the mask, then etching the major surface through the exposed regions. The mask is then removed and impurities introduced into the exposed surface to form a photovoltaic PN junction. <IMAGE>
Patent GB-2042132-A (GB)
Title: Valve operating mechanism
IPC: F16K1/32
Filed: 1980-01-29
Abstract: A valve port 4 is closed by axial movement of a shaft normal to the port, the shaft having a closure plug 6 which beds down on to the port seating 5. A spring closing force is normally applied by a take-up spring 16 between the valve actuator 11 and the shaft so that the greater the spring closure force the greater has to be the force of the actuator. An auxiliary spring 21 acting directly on the shaft or the closure plug assists the take-up spring to close the valve without putting any further load on the actuator. <IMAGE>

Title: Fancy Yarn
IPC: D02G3/34
Filed: 1980-01-31
Abstract: Fancy yarns are produced by drafting together a draftable foundation roving 16, for example comprising wool fibres, and an effect yarn 20, which may be of staple or continuous fibres, and twisting them together on a spinning frame.

Title: Pick-up assemblies for record players
IPC: G11B3/31
Filed: 1980-08-12
Abstract: A pick-up arm assembly for a record player, especially a child's or toy record player, has a pick-up arm (2) pivotally mounted on a support arm (1), the support arm being mountable on the record player to pivot only about a horizontal axis (14) for movement toward and away from a record on the turntable.

Title: Method of preparing a phenolic aldehyde resin; adhesive coating compositions
IPC: C08J5/04
Filed: 1981-06-04
Abstract: A method of preparing a thermoplastic, water-soluble, phenolic aldehyde resin involves two steps. Firstly, the phenolic compound and aldehyde are reacted to less than 100 percent completion at an aldehyde to phenolic compound mole ratio of 0.6 to 1.5 and at a pH of 3.5 to 5.5 for 3 to 10 hours at a temperature of 13 to 32 DEG C. Secondly the pH of the reaction is adjusted to above 7.0 to 7.5 and the reaction is continued between the unreacted phenolic compound and aldehyde and resinous mixture to produce a resinous mixture that has a predominant amount of trimer polymer with slight cross-linking and a minor amount of dimer and higher oligomers. The phenolic compound is preferably resorcinol or a mixture of resorcinol and phenol. The resin mixture is processed into an adhesive by combining it with one or more elastomeric latex and various latex additives. The adhesive is aged and has added to it an amine or ammonia to tie up any unreacted aldehyde. Also additional phenolic compound may be added. The adhesive is used to coat filamentary materials in particular glass fibres and the coated filamentary materials are dried to produce reinforcement material for rubber. Uses:- Tyre cords adhesives

Title: Circuit for discriminating secam television signals
IPC: H04N9/64
Filed: 1981-09-17
Abstract: In a SECAM (Registered Trade Mark) color television receiver, a discriminator circuit is provided for rejecting signals of other color television system formats to allow the receiver to process a received SECAM signal in cases where the receiver is tuned to the frequency bands of other system stations. A color subcarrier is extracted through a gate (8) in response to each horizontal sync pulse from the back porch of each horizontal sync pulse of a received color television signal. If the received signal is a SECAM system signal, the extracted color burst alternates in frequency between the SECAM subcarrier frequencies of 4.25 MHz and 4.40625 MHz. A band-pass filter (16) is provided having a passband of which the center frequency corresponds to a harmonic frequency (e.g. third harmonic) of one of the color subcarriers of the SECAM system. A frequency discriminator (18) is connected to the output of the band-pass filter (16) to detect when the filtered burst signal occurs at one- half the line frequency of the SECAM system for indication that the received signal is in the SECAM format. <IMAGE>
