Title: Seamless tube mill
Inventor: POZSGAY DEZSOE ALBERT
IPC: B21B19/02
Filed: 1984-06-28
Abstract: The mill installation comprises a cross roll piercing mill 15 for piercing and initially elongating a solid cylindrical billet. Preferably, but not in all cases, the cross roll piercer is followed by a second cross roll "piercer" which functions purely as an elongator, and which functions to substantially elongate the pierced billet, typically in conjunction with an increase in O.D. and reduction in wall thickness. As a key feature, the pierced billet, previously processed by either one or two cross roll piercer/elongators, is thereafter further elongated by means of a Diescher-type elongator 19 incorporating a mandrel bar restrained from moving through the mill at the velocity of the billet. From the Diescher mill, the highly elongated tube is processed on a sizing mill 21 for finish sizing and typically some additional elongation. The mill complex makes it economically feasible to install a seamless tube mill for the production of high quality tubing at production levels as low as 200,000 - 250,000 tons per year. <IMAGE>

Title: Planning circuit routes
Inventor: HOSKING KEITH HERBERT
IPC: H05K3/00
Filed: 1985-08-24
Abstract: In the zone by zone computer planning of track routes for multi- layer printed circuit boards and the like the computer may be unable to route a track through a zone because of the presence of a via-hole or because other tracks have been forced to detour round a via-hole, so taking up all the available space. The solution of the invention is that at such a juncture the computer should display the routes so far to the Operator, indicate the tracks that cannot be routed (31), point out the via-hole (or via-holes) that may be the cause of the trouble (V6), and allow the Operator to take such action - by moving a via-hole to a different place (V6') - as will permit the computer to progress beyond the problem point (either after a fresh start, or simply by continuing from the point affected by the Operator- induced change). <IMAGE>

Title: Preparing optical fibres for splicing
Inventor: HEINECKE RUDOLF AUGUST HERBERT
IPC: G02B6/38
Filed: 1986-02-21
Abstract: A plastics coated optical fibre is prepared for splicing or termination by stripping the plastics from the fibre, optionally bonding hydroxyl groups to the fibre surface, and providing a coating on the surface whereby the strength of the fibre adjacent the fibre end is maintained or enhanced. Preferably the plastics coating is removed by plasma etching using O2 and/or CO2 as the reactant gas and optionally Cl2 or F2. H2 may be admitted to the plasma to render the fibre surface saturated with OH groups. The strengthening coating may be provided by TiCl4 vapour, silane and N2, or alloys. Alternatively, the plastics coating may be solvent stripped and the OH groups provided by an aqueous solution.

Title: Fricton clutch
Inventor: HIGGINBOTTOM CHARLES
IPC: F16D13/71
Filed: 1986-03-24
Abstract: A clutch (2) with a driving plate (4) rotated by a power source, and a driven plate (8), and a clutch cover assembly (10). The assembly (10) comprises a cover pressing (12) with a rim flange (50), a pressure plate (14), and a diaphragm spring (16). The assembly (10) is secured to the driving plate by bolts (54) through the flange (50). Belleville washers (64) surrounding the bolts (54) are disposed between the flange (50) and the bolt heads (56). When the clutch is disengaged by release bearing (26) being pulled in direction A, the Belleville washers (64) cone and the flange (50) presses on the driving plate (4). When the clutch re-engages by allowing the diaphragm (16) to urge the pressure plate (14) towards the driving plate, the increased gripping of the driven plate (8) between driving plate and pressure plate is resiliently cushioned by flattening the Bellevilles (64) as the flange (50) moves slightly from the driving plate (4).

Abstract: A contaminated gas laden with liquid droplets is filtered outwards through a tubular filter element 20 located in a housing 15 within a biological shield. A heater 32 enclosed by a separate casing 31 inside the filter element 20 keeps the element above the dew point of the liquid and thus prevents the liquid from clogging the filter element, which retains the solid content only. The heater is removable independently of the filter element, which is clamped in place by a plug 29. The filter may be connected downstream of a mist separator which treats gas used to raise liquids inside the biological shield. …<IMAGE>…

Title: Equalizer for linear modulated signal on radio channel
Inventor: SEFATY SALOMON
IPC: H04B3/10
Filed: 1990-09-06
Abstract: The linear modulated signal is received in blocks or frames and the impulse response of the channel is estimated during training sequences before and after a frame. Interpolation is used to estimate the impulse response at each point in the frame. From this, the coefficients of an equalizer 24, 26 are calculated for equalising the signal. The technique is particularly applicable to land mobile radio systems using 16QAM or other linear modulation schemes. It can compensate for Rayleigh fading and multipath spread. <IMAGE>
