Patent GB-1234951-A (GB)
Title: Apparatus for measuring changes in distance
Inventor: LIGHT LEON HENRY
IPC: A61B5/113
Filed: 1968-03-27
Abstract: 1,234,951. Measuring changes in distance, electrically; monitoring breathing. NATIONAL RESEARCH DEVELOPMENT CORP. June 26, 1969 [March 27, 1968], No. 14772/68. Heading G1N. In monitoring a patients breathing, transmitting and receiving coils 11 and 12 are attached to the patients chest and back and the gain of amplifier 13 is automatically adjusted so that is output does not depend on the distance between the coils 11 and 12 after a comparatively long time interval following a change in said distance but does depend on changes in said distance occurring in comparatively short intervals. Thus there is no need to manually adjust the sensitivity of the apparatus when fitted to different patients. The automatic adjustment may be done by controlling the gain of one of the stages of the amplifier or by using negative feedback with a long time delay. Diodes (42-45) Fig. 2 (not shown) may be connected to short out the long time constant filter when the input signal changes greatly thereby enabling more rapid settling after the coils 11, 12 have been applied to the patient. The coils 11, 12 may be of copper ribbon on flexible plastics sheets and may be attached to the patient by double-sided adhesive tape. The transmitter coil is preferably of large area to reduce the effect of any component of motion at right angles to the axes of the coils.

J., (trading as MORGAN BROS.), Victoria Works, Pontypridd, both in Glamorgan. May 20, 1931, No. 14947. [Class 31 (i).] Stationary -cutter machines.-Machines for recovering rubber from disused tyres, by severing the bead from pneumatic tyres or stripping solid tyres from their rims, include one or more concave circular cutters. A support for a pneumatic tyre 24, Fig. 1, from which the bead portion 25 is to be cut by a concave rotary circular cutter 13 driven from the main drive shaft 7, comprises a pair of conical rollers 15 which may be driven to assist the rotation of the work, providing a gap for the knife and being carried by a pivoting table 14 actuated by a pedal-operated lever 21 engaging a cam surface 20 beneath the table. A construction is also shown in which the table and cutter are duplicated, the two tables pivoting in opposite directions, and both beads being cut simultaneously. An adjustable guide wheel 18 is provided for contacting the inner surface of the tyre. In a further modification of this part of the machine, the work 44, Fig. 3, is stationary, while knives 13 are carried on shafts 38 driven through universal joints 39 from the shafts 40, and pivoting simultaneously towards or away from the work upon actuation of a lever 42. The part of the machine for severing solid tyres 54 from their rims comprises a pivoted table 49 controlled by a handle 52, and a concave disc cutter 13 driven through friction clutches &c. 48 from the shaft 7. Bevelled washers 56 on the cutter deflect the separated tyre from its rim. An adjustable driven roller may be carried on the table to feed the work to the cutter.

Title: Inductive coupler
IPC: H01F38/14
Filed: 1947-06-06
Abstract: 625,217. Radio frequency coupling arrangements. STANDARD TELEPHONES & CABLES, Ltd. June 6, 1947, No. 14994. Convention date, Nov. 14, 1945. [Class 40 (v)] An inductive coupler comprises a pair of loops inductively coupled, at least one loop being divided into segments, each segment being such that the standing wave ratio over its length does not exceed #2. The arrangement is intended to provide substantially con. stant current flow at all points on the coupling loops, to avoid variation in couping when one loop is rotated. Fig. 3 shows the invention applied to a rotating antenna coupling system. Motor 20 is used to rotate antenna 18 and an associated loop which consists of three segments 11, 12 and 13. These segments each of which is less than a quarter wavelength, are fed in parallel from common points 3 and 4 on the aerial leads 1 and 2, so that the current round the whole loop is substantially constant even at ultra high frequencies. A stationary loop similarly composed of segments 11c, 12c, 13c, and connected to the feeder leads, is inductively coupled to loop 11, 12, 13. More than three segments may be provided, and only one of the loops may be constructed in segments.

Title: Improvements relating to looms of the gripper-shuttle type
IPC: D03D47/24
Filed: 1948-06-03
Abstract: 640,214. Gripper shuttle looms. SULZER FRERES SOC. ANON. June 3, 1948, No. 14995. Convention date, June 5, 1947. [Class 142(ii)] In order that the transfer device, which draws back the cut end of weft from the selvedge and presents it to the next gripper shuttle, may have its jaws 46 normally closed, the weft 5, as it is running into the shed, is deflected out of the path of the jaws by a movable guide 38. When a shuttle reaches the opposite side of the loom, the jaws 46 (which have meanwhile moved to the selvedge) are opened by a wedge 60 and the guide 38 brings the weft between the jaws, which are then allowed to close on it by withdrawal of the wedge. The weft is next cut at the selvedge and the jaws 46 then return to the position shown where the weft end is gripped by another shuttle. A wedge 59 opens the jaws 46, the shuttle is picked, and the guide 38 moves the weft clear of the jaws, which are then allowed to close again.

Abstract: 570,231. Cobaltic hydroxide. MOND NICKEL CO., Ltd., WALLIS. A. E. and WEST, D. H. Nov. 28, 1941, Nos. 15369/41 and 12531/42. [Class I (iii)] Nickel is removed from impure cobaltic hydroxide, for instance that obtained by the process of Specification 570,230, by digestion in an acid liquor containing at least one cobalt salt, which may be obtained from the precipitate itself by treatment with acid. The pH of the extracting solution may be between 0.9 and 2.0 and the solution and precipitate may flow in counter-current through a number of digestion vessels. Digestion may take place at 70‹C. or above, but when the acid is used to extract cobalt from the precipitate, this step may be carried out at a lower temperature in the presence of a reducing agent such as sulphur dioxide, sodium sulphite or bisulphite, or reduced cobalt oxide.

Abstract: 1,126,976. Terminal boards. AMP Inc. 30 March, 1967 [7 April, 1966], No. 15495/66. Heading H2E. A method of assembling, on a chassis panel 21, an electrical connector mounting strip 12 formed from a synthetic resin bonded laminated insulating material with holes for receiving electrical conductors and, along one edge, one or more projections 14, 15, 16, comprises applying pressure to the strip to resiliently deform it, inserting the projections into holes 22, 23 and 24 in the chassis panel and relaxing the pressure to allow the projections 15, 16 to latch on to the panel. The notches 17, 18 in the projections 15, 16 may face in the same or in opposite directions, and the lower edge of the projection may be flat (Fig. 1, not shown), or have an angled taper 19, 20. In an alternative arrangement (Fig. 3, not shown) in which two projections are employed, one has a shoulder (37) parallel to the lower edge of the strip (30) spaced below this edge level with the lower side of the notch (34). Both projections have sloping lower edges and fit in simple rectangular apertures in the panel, the shoulder locking the mounting strip firmly in position. The chassis panel 21 may have a small upturned tag at one end of an aperture (Fig. 4, not shown) which can be pushed down flush with-the surface and helps to lock the mounting strip in position.

A coil unit for assembly with one or more like coil units comprises a coil winding 1 and a metal housing 5 adapted to contain the winding, the housing having one side 8 open such that when two such coil units are assembled together the housings thereof interfit so that a substantial part of the open side of one housing is filled by the housing of the other. The winding 1 is wound around a toroidal core and has fixed thereto two terminal boards 16, so that when the coil is placed into the housing over the shaft 10 and insulating spacer 3 the terminal boards are accommodated in cut-outs 15. The housing 8 is provided with an enlarged diameter 9 which fits over the normal diameter of an adjacent housing 5, the spigot 13 of one spacer 3 passing through the hole 7 of the adjacent housing in a recess 14 in the adjacent spacer to insulate the shaft 10 from the housing 5. Each housing acts as a screening means for its associated coil and when a number of coils are assembled on the rod 10 and clamped together by means of nuts on the rod the spacers 3 prevent any pressures being placed on the coil windings. Coil assemblies for telephone and the like loading coil assemblies may comprise a plurality of such units mounted on a number of rods 10 parallel to each other.
