Patent GB-2055325-A (GB)
Title: A method and an apparatus for controlling the feeding of a bandsaw blade
IPC: B23Q15/12
Filed: 1980-06-10
Abstract: An apparatus for feeding a bandsaw blade into a workpiece at a constant rate comprises a motor 37 for feeding the blade. An angle detector 43 determines the angular position of the blade with respect to the workpiece M and relays this information to a register 49. Using the same information together with data on the shape and size of the workpiece and the optimum cutting rate for the workpiece material, a computing unit 51 calculates the desired angular position of the blade. This is stored in another register 57. A comparator 53 compares the actual and desired angular positions and gives a signal to a motor controller 55 to adjust the actual angular position, if not at the desired angular position, so as to feed the blade into the workpiece M at the optimum cutting rate. <IMAGE>

Title: Transcutaneous photometric measurement of blood component
IPC: G01N21/47
Filed: 1980-07-03
Abstract: The transcutaneous, photometric determination of the concentration of a component such as a gas in blood is effected by causing the blood component to be measured to diffuse through a semipermeable membrane (3) into an indicator solution in a chamber (9a). The surface of the indicator solution is irradiated with monochromatic light of a frequency at which the intensity of the light reflected by the surface of the indicator solution measurably depends upon the concentration of the blood component. Changes in light intensity in the reflected beam are employed to indicate the concentration to be determined. Light is conveyed to and from the surface of the indicator solution by optical fibres (11). A heater (6) surrounds the area of measurement. The blood component passes through a porous ceramic body (5) to a porous pad 9 in the chamber (9a). <IMAGE>

Title: Production of linear aromatic polyester
IPC: C08G63/78
Filed: 1981-10-21
Abstract: A problem associated with known techniques of preparing a polyester by transesterification polymerisation from a hydroxylic reactant and a diaryl ester of a dicarboxylic acid using either a stoichiometric equivalent proportion of hydroxylic and diaryl ester reactants or a large excess of diaryl ester is the tendency of the polyester to develop an undesirable yellow color. This can be overcome by effecting trans-esterification polymerization of a diaryl ester of a dicarboxylic acid and a hydroxylic reactant comprising a major proportion of a bisphenol employing an excess of from 0.05 to less than 1.8 mole percent of said diaryl ester over the stoichiometric equivalent proportion of said diaryl ester with respect to said hydroxylic reactant. The resulting polyesters can be moulded to produce shaped articles.

Patent GB-2092041-A (GB)
Title: Upsetting and swaging hollow bodies
IPC: B21J5/08
Filed: 1981-12-10
Abstract: To locally increase the wall thickness of a shell of a hollow body, that portion of the hollow body in which the wall thickness is to be increased is heated and the hollow body is then subjected to an axial pressure sufficient to upset said heated portion. In order to permit a fast and economical formation of a portion of increased wall thickness of virtually any desired shape on the shell even of a thin-walled hollow body without any risk of a formation of folds or cracks, the heated shell portion is upset and is simultaneously subjected to a swaging operation by which the material which tends to bulge outwardly under the axial pressure is confined within the desired shape of the outside surface of the shell portion which has been increased in wall thickness. <IMAGE>

Filed: 1982-05-17
Abstract: A knitted fabric drawing device in circular knitting machine comprises plurality of take-up rollers (2) having horizontal axes arranged around the machine and cooperating with pressure backing rollers (6). The take- up rollers (2) are advanced angularly by means of respective ratchet members (9, 10) which are driven through rod-like elements (11) subjected to the action of a rotatable detent (15) which, in moving about the machine axis, radially displaces in succession all of the rod-like elements (11) against the action of a pressurized fluid in a chamber (18), but without advancing the take-up rollers (2) themselves. As the action of the rotatable detent (15) is discontinued, the rod-like elements (11) are returned to their rest or inoperative position under the influence of the pressurized fluid, thus advancing the respective take-up rollers (2). By changing the fluid pressure level, the drawing force can be varied, even while the knitting operation is in process. <IMAGE>

Title: Pulse doppler radar units
Inventor: WEIS KLAUS
IPC: G01S13/528
Filed: 1982-06-26
Abstract: Pulse Doppler radar MTI units use different pulse repetition frequencies (PRF1, PRF2) and for the suppression of slow moving targets an overlapping of range is effected by periodically changing at 3 the PRF within each target -observation-time (TOT). In accordance with the PRF change the signal processing is divided into a near range B and a remote range A. During the transmission of radar signals of high PRF, at a high lower cut-off frequency of the moving target indicator (MTI) only the near range is analysed,whereas during the transmission of the low PRF only the remove range is analysed. <IMAGE>
