Patent GB-2062696-A (GB)
Title: Pile Fabric Knitting
IPC: D04B9/12
Filed: 1980-11-11
Abstract: A pile fabric has its basic fabric structure knitted from ground yarns (Y1) and a pile formed from pile yarns (Y2). Of the pile yarn wales at least one wale is constructed of cut pile stitches ([ DELTA l) and one or more other forms of stitch ([O], [X], []). A knitting machine with two needle beds has some or all needles in one bed replaced by blade- attached needles (1) and lifting (21) and lowering cams (22) therefor. By raising the needles (1) to a knitting position, by means of the cams (21), pile stitches held on the needles (1) are cut through forming a cut pile in the fabric. <IMAGE>

Title: Magnetooptic memory medium
IPC: H01F10/13
Filed: 1981-02-20
Abstract: Disclosed is a new magnetic storage medium including a layer of amorphous material typically GdDyFe whose Curie recording point is lower than its crystallization point (e.g., 120 DEG C for 350 DEG C) to enable crystallization to cause variations in its optical properties such as transmittance or reflectivity for thermomagnetic writing. Reversible recordings are set up on the amorphous material layer by thermomagnetic writing technique for example the Curie point writing, while unchangeable or permanent recordings are set up on the amorphous material layer through laser-activated crystallization of the amorphous material layer.

Title: Improvements relating to fittings for light bulbs
Inventor: CROKER BRIAN HENRY
IPC: H01R33/18
Filed: 1981-09-10
Abstract: A socket for the receipt of a light bulb or some other plug-in electrical fitting has a collar 12 which will receive the base portion of the fitting so that the fitting will make contact with pins 14 and 15 connected to the electrical supply. Levers 16 are biased by a spring 24 into contact with the outside of the collar 12 to cause shaped portions 18 to project through slots in the collar for location in a groove formed around the circumference of the base of the fitting to hold the fitting securely in place. This arrangement provides for rapid insertion and release of the fitting within the socket. As an alternative the base of the fitting could have projecting pins 27 received in vertical slots in the collar 12 and held in place by releasable arms 30 which are biased downwardly into contact with the projecting pins. <IMAGE>

Title: A method for producing a multifilament thread
Inventor: BRUCHER HANS WALTER
IPC: D02G3/24
Filed: 1982-06-02
Abstract: A method of producing a multifilament thread composed of individual filaments of the multi- component matrix segment type, in which the thread has a false twist crimping obtained by a false twist treatment during which there is applied a fixing temperature corresponding to at least the temperature needed for fixing the component with the lowest melting point. The twist density of the thread is selected between about 1,500 and 4,500 twists per metre as a function of the total titre of the multifilament thread composed of individual filaments of the matrix segment type. By this method the individual components are bonded in the thread bundle at irregular intervals by spot bonds which grasp the thread cross- section partially or completely. <IMAGE>

Patent GB-2124919-A (GB)
Title: Filter/strainer construction
Inventor: BRADLEY MICHAEL VICKERY
IPC: B01D35/12
Filed: 1982-08-12
Abstract: The filter/strainer has a body (11) with two parallel through-passageways (12,13) which are not normally in fluid communication with one another. Each through passageway includes a chamber (15) in which is placed a replaceable porous medium (16) able to retain insoluble contaminants found in a fluid which is passed through one or the other of the passageways. The inlet/outlet orifices of one or other of the passageways are closed or opened, simultaneously, by movement through an arc of two gates (23) connected each to a lever 30, the levers being joined by operating bar (33), all mounted externally of the body. A balance valve (36) enables line- pressure fluid to be bled gradually into the empty one of said two chambers; this facilitates movement of the gates at change-over and prevents damage to the porous medium which would be caused if said medium were to be subjected to a sudden in-rush of fluid under line pressure. <IMAGE>

Patent GB-2111197-A (GB)
Title: Photoconductive detector bias
Inventor: ELLIOTT CHARLES THOMAS
IPC: H01L31/09
Filed: 1982-11-30
Abstract: It is a problem extracting the photosignal component from detector output, to the exclusion of pedestal bias response. To overcome this, a time varying bias signal is applied to the detector. The duration of the time varying bias signal, or if a periodic signal, the signal period, is chosen as long compared to photocarrier lifetime and the signal amplitude is large enough to range over a non-linear portion of the responsivity characteristic of each element. The bias signal contains a d.c. component so that the bias signal ranges about a point of operation-a point of asymmetry lying on the responsivity characteristic. The photosignal component of the output signal may be removed by time averaging or by harmonic separation. Alternatively the alternating component of the bias signal may be amplitude modulated at a lower frequency, and the photosignal component extracted by detection of demodulated signal. <IMAGE>

Title: Improvements in or relating to the fixing of diffuser members
Inventor: RODGERS ALVIN
IPC: B05B15/658
Filed: 1983-03-22
Abstract: A porous or finely apertured diffuser dome 3 having a fixing hole 15 is fixed to a mounting 2 therefor by a stud 5 of plastics material one end 6 of which is engaged in an aperture 4 in the mounting 2 and the other end of which passes through the fixing hole 15 in the dome 3 where it is secured by a wing nut 8 of plastics material. The end 6 of the stud 5 engaged in the aperture 4 in the mounting 2 is formed with at least one groove 11 extending substantially parallel to the axis of the stud 5 to establish communication between the space below the mounting 2 and the space below the dome 3. The arrangement is particularly suitable for fixing porous diffuser domes to a plastics air distribution pipe 1 in plant for the aerating of activated sewage sludge. The arrangement obviates the need for brass inserts which have previously been used in the mountings but which are liable to be pulled out with rupturing of the mounting upon over tightening. <IMAGE>
