Patent GB-2130050-A (GB)
Title: Calling line identifier
Inventor: CASS JOSEPH RICHARD
IPC: H04Q3/72
Filed: 1982-10-28
Abstract: In a telephone exchange calling line identifier, a relatively long identification pulse is applied via drive means (6) to the P-wire of the switched path at a "concentration point" in the exchange. This pulse propagates back via the first selector (2) to the caller's line circuit (1). Here it is detected on scan by scan means (7), which scans a number of cycles of a block of lines during the persistence of the CLI pulse. Thus the calling line is detected, but this detection has to be repeated on eight successive scans to be accepted as valid. The identifier is an add-on assembly, and is modular in nature and is microprocessor controlled. As described, it forms part of a call logging system. <IMAGE>

Patent GB-2146186-A (GB)
Title: Apparatus for electrically heating a metallic workpiece
Inventor: BROOKS DAVID STUART
IPC: H01R41/00
Filed: 1984-08-13
Abstract: The apparatus is primarily for use in contact welding and induction heating applications and has a pair of bus bars 10, 12 for connecting a low impedance load (typically 0.01 ohms) to a high power high frequency alternating current generator. For impedance matching purposes, the generator has a step-down transformer for connection to an input end of the bus bars, and parallel capacitance 20A to 20F is connected across the bus bars 10, 12 adjacent the load to allow transformation of the resistive component of the load to a higher value of effective shunt resistance using the inherent inductance of the bus bars and the load. A variable inductance element 40 may be coupled in series in bus bar 12 between the capacitance and the load to achieve optimum matching with different loads. The inductance is varied by means of a fluid-cooled, member 46 slidable between plates 42, 44 projecting from bus bar 12. In a further embodiment, two or more loads can be connected to a single transformer coupled generator output via respective pairs of bus bars, each pair of bus bars having a shunt capacitance and a variable series inductance as mentioned above (Fig. 7). <IMAGE>

The retaining portions (13) at the internal end of the catheter tube are deflectable to facilitate insertion of the tube in the body. <IMAGE>
Patent GB-860389-A (GB)
Abstract: 860,389. Inserting rubber pins in soles. ODERMATT, A. Oct. 21, 1957 [Feb. 27, 1957], No. 32741/57. Classes 17(1) and 17(2) Rubber pins 47 are introduced into through holes in a leather sole 49 by gripping the pins in the ends of gripping members 5 pushed through the holes, pulling the members back so that the pins are compressed and located in the holes, and then withdrawing the members from the holes whilst leaving the pins in position in the sole. As shown, supporting plate 3 has holes 4 arranged in required pattern and aligned with sleeves 5 secured to a plate 6 which is secured to a bush 8 movable lengthwise in cylinder 7 by means of shaft 12, crank-pin 11, and rods 10, 9. Pins 14 supported on a plate 15 are arranged in sleeves 5 and are adjusted lengthwise by means of eccentric 18, Pressure plates 25, which have spikes 46 to collect rubber sheets 48 with the pins 47 at location A and transport them to a position above plate 3, are carried by a boss 22 rotatably carried on a column 21 supported by spring 20, and are movable lengthwise with the column by shaft 29, geared for equal movement with shaft 12, and acting via disc 30, driving pin 31, crankarm 27 freely rotatable on shaft 29, link 28 and draw rod 26. Shafts 12, 29 are first turned by hand until sleeves 5 project above plate 3 by about the thickness of a sole 49, and a sole positioned thereon. A grating 40, normally retracted as in Fig. 2, is then positioned over the sole to prevent lengthwise movement thereof, and is located by stop 45. A plate 25 carrying a sheet 48 is positioned over plate 3, and an electric drive for the shafts then operated. Sleeves 5 rise and lugs 50 grip pins 47, then the sleeves and plate 25 descend. Holes 4 close lugs 50, compressing the pins which move into the holes in hole 49 and are retained therein by pins 14 as sleeves 5 withdraw. Spring 51 permits continued movement of column 21. Spring 20 raises plates 25, when arm 27 permits, and spikes 46 are withdrawn from sheet 48. The pressure exerted by plates 25 is adjusted by means of nut 52. The sheet 48 may be coated with adhesive on the side carrying pins 47, and plates 25 may be warmed electrically to improve adhesion to the sole. A second thinwalled sleeve may be arranged between sleeve 5 and pin 14 and slit to form lugs which cover the spaces between lugs 50.

Patent GB-2212033-A (GB)
Title: Time synchronisation
Inventor: CLARK ADRIAN PERCY
IPC: H04L7/00
Filed: 1987-11-04
Abstract: A method and apparatus (Fig. 1) for synchronising the sampling frequency at reception of digital data utilises a timing correction algorithm which takes into account level changes in the signal due to fading or multipath propagation, by presuming that the relative change in level, due to fading, is essentially the same for corresponding samples, i.e:-      Yo,i-1,h/Yo,i,h/ SIMILAR Yo,i-1,h-1/Yo,i,h-1 Use of this presumption in the otherwise known error algorithm ensures that a pure fade does not per-se introduce sampling frequency errors. The precise sampling points used in the algorithm may depend upon transmission conditions. <IMAGE>
