Patent GB-2042703-A (GB)
Title: Drying of Web Material
IPC: H05B6/78
Filed: 1980-01-28
Abstract: This invention relates to a method of drying wet lengths of material by microwave power. The power is passed from a microwave generator 3 into a circulator 1 and thence to an obstacle 8 into one end of a closed elongate waveguide 7 tuned to come into resonance with the frequency of the generator when wet material is present in the waveguide. The material is passed through longitudinal slots 9 located along the centre lines of the broad faces of the elongate waveguide. A strong electric field of the given frequency is produced in the plane of the material. Power which is not absorbed by the material is returned to the circulator 1 and passed from it to a dummy load 5. In a preferred embodiment of the invention the material, after passing through a first section of waveguide, is passed through a second section of waveguide. The second section of waveguide is so disposed relative to the web and the first section of the wave guide that the nodes and antinodes of the standing wave pattern of microwaves in the second section corresponding to different positions on the material compared with the positions of the nodes and antinodes in the first section. <IMAGE>

Title: Rolling of bars rods and wire
IPC: B21B37/52
Filed: 1980-02-29
Abstract: The speed of the motor (17) of the last or last two stands of a block (7, 11 or 12) of rolling stands in a rolling line for bars, rods or wires is increased as the leading end and trailing ends of the work-material pass through those stands to increase the tension in these end portions.

Title: Fabrication of optical fibres utilizing thermophoretic deposition of glass precursor particulates
IPC: C03B37/02
Filed: 1979-08-10
Abstract: The deposition of glass precursor particulates, during optical fiber fabrication, is rendered more efficient by increasing the thermal forces which play a significant role in directing the particulate material an appropriate substrate.

Title: Measurement of basis weight by radiation gauge
IPC: G01D3/02
Filed: 1980-06-20
Abstract: For accurate measurement of the basis weight (mass per unit area) of a material such as paper between a radioactive source 12 and an ionization chamber 18 the apparatus is calibrated by sing a plurality of standards (eg. 34c) of known basis weight to provide a relationship between basis weight and the output current of the chamber which includes at least terms of the second order and preferably terms of higher orders. The major portion of the radiation path is enclosed in airtight chambers (52, 54) which are sufficiently rigid that the density therein is independent of ambient temperature and pressure variations. The accuracy is increased by measuring ambient temperature and pressure fluctuations, and linearly compensating for resultant density variations in the air gap (10) through which the paper web passes. A wheel 32 holding the standards is induced by a motor 40 and a perforated encoding disc 44. <IMAGE>

Title: Reducing particle loss from fluidised beds
IPC: B01J8/24
Filed: 1980-10-20
Abstract: The loss of particles from a fluidised bed is reduced by providing near to an upper surface of the bed a plurality of elements defining between them gaps which are sufficiently large for the bed particles to pass therethrough and are distributed substantially evenly across the bed.

Title: Sausage casing automatic closing machine
IPC: A22C13/00
Filed: 1980-11-06
Abstract: A system for automatically closing one end of a shirred casing strand. A strand is to be automatically presented to an associated closer mechanism (46) in alignment therewith and under a preselected pressure. A transfer device (44) is provided for receiving a doffed strand (40), transferring the strand transversely and then moving the strand longitudinally so that an end of the strand engages the closer (46). A gripping mechanism is provided which includes a pair of jaws (98) having opposing clamp elements (102) of a generally V-shape or angled cross section. The two jaws are simultaneously movable either together or apart and are urged apart by compression springs (104). A fluid cylinder-actuated linkage urges the jaws towards closed positions. By varying the closing force, the clamp members (90) can be first moved to a pre-set spacing providing a receptacle into which a doffed strand of a predetermined size may be readily slid. Then by increasing the pressure of the cylinder, the strand may be sufficiently tightly gripped to prevent relative movement during the closing operation. The closer members are separated to release a closed strand at the end of the closing operation. By varying the pressure to the cylinder in the receptacle forming stage of the clamping members, the size of the receptacle may be adjusted in accordance with variations in size of casing strands to be handled. A control system for the automatic operation of the transfer device in conjunction with the closing device is provided.

Title: Systems and methods for logging a borehole while drilling
IPC: H01M50/251
Filed: 1978-12-04
Abstract: Measured downhole parameters cause pulses of pressure drop in the liquid (drilling mud) pumped to circulate in the boreholes these pulses being superposed upon a periodic pressure variation in the mud (e.g. produced by the pump). The pulses are generated by rapidly opening and shutting a valve (36) in a comparatively wide bore passage which bypasses the drill head (26) or hydraulic motor which restricts mud flow in the borehole. A receiver (100) in the high pressure side of the mud flow path and positioned at the earth's surface is equipped with means (102) which combine the received superimposed signals with signals representing the pump induced variations in order to extract the parameter pulses. <IMAGE>

Title: DC to DC converter
IPC: H02M3/338
Filed: 1981-08-19
Abstract: A self-oscillating DC to DC converter is mainly composed of two or four transistors, three transformers (1, 11, 21) (a converting, a driving and a current transformer), a resistor (18) and an inductance (20). The operating frequency is fixed by the saturation characteristic of the driving transformer. Base currents of the transistors are supplied mainly by the current transformer (21) in proportion to their collector currents so the operating frequency is constant in spite of the load fluctuation. The inductance (20), which is connected in series between a winding (5) of the converting transformer (1) and a winding (14) of the driving transformer (11), prevents the two or four transistors from being 'on' simultaneously. <IMAGE>
