Patent GB-1279599-A (GB)
Title: A flexible metal tube
IPC: H01B13/26
Filed: 1970-12-11
Abstract: 1279599 Corrugated metal tubes CABLES DE LYON ALSACIENNE 11 Dec 1970 [18 Dec 1969] 59148/70 Heading F2P A flexible tube is formed from corrugated metal strip wound so that the edges A, B are longitudinal and that the ends of the strip overlap with edge A abutting a line of discontinuity C, wherein the corrugations of the strip portion AC are progressively longitudinally offset so that the corrugations at line C are offset one-half of a corrugation width with respect to the corrugations at edge A, and the corrugations of portion CB are offset one-half of a corrugation width with respect to the corrugations of portion AC at line C. The overlapping ends of the strip are welded together or connected by adhesive. The strip is of bimetallic material. The tube is used as an external conductor or sheath of an electric cable.
Patent GB-1453040-A (GB)
Title: Signal storing circuitry
IPC: G11C11/411
Filed: 1973-12-28
Abstract: 1453040 Semi-conductor bi-stable circuits SIEMENS AG 28 Dec 1973 [29 Dec 1972] 60008/73 Heading H3T Only one of a plurality of bi-stables can be in the "set" state at a time. Each bi-stable 1, 2, 3 has one of its cross-couplings completed through a common delay circuit 12 so that a setting input S1, S2, S3 must be maintained for at least the delay period, and also has a respective feedback gate 14, 16, 18 which is blocked if any other bi-stable is in the set state. The blocking inputs to feedback gates 14, 18 are each derived from the outputs of the other two bi-stables by means of OR gates 25, 26; and the blocking inputs to feedback gate 16 come directly from bi-stables 1, 3 via inverters 22, 24. The delay 12 which may be an RC circuit receives the outputs of all bi-stables through an OR gate 10, and controls not only all the feedback gates 14, 16, 18, but also all the setting gates 13, 15, 17 thus blocking all bi-stables from further setting inputs. Reset inputs L1, L2, L3 are applied directly, although these also require the reset signal to be maintained for the delay time. Output AND gates 19, 20, 21 are controlled by the delay 12 output. The bi-stables use NOR gates 4 to 9, and in a two-bi-stable embodiment (Fig. 2, not shown) NAND gates are used.

Patent GB-1304880-A (GB)
IPC: G06V30/10
Filed: 1970-12-22
Abstract: 1304880 Character recognition systems INTERNATIONAL BUSINESS MACHINES CORP 29 Dec 1970 [2 Jan 1970] 61426/70 Heading G4R In a character recognition system the end of a character is determined by a segmentation unit 18, Fig. 1, enabled by a unit 12 which delivers signals related to the leading and trailing edges, as determined from one line scan to the next, of the character being scanned. The unit 12 determines the number of leading edge bits P in each scan path, the number of trailing edge bits N, and the scan density L, i.e. the number of black bits in the scan path. For example if the scan paths are vertical scan path 15, Fig. 2, has a scan density L=6, 3 leading edge bits P as viewed from the right of the character, and 11 trailing edge bits N (i.e. the number of bits that have changed to white since the last scan path 14). These values are variably weighted and added, dependent on the topological parameters of the character, to derive a decision threshold T which determines the scan at which sectioning should occur. Unit 12 enables unit 18 at appropriate times so that, for example, if the segmentation unit can separate hard-touching characters it will not be enabled during the middle of the character so that it cannot separate the character into two half characters. The threshold T may be calculated by a digital computer. During a first raster scan of the whole character the values P, N and L, and values derived from them, are calculated. At the end of this scan the weighting values are updated, dependent on P, N and L. During a second raster scan the threshold T is determined over each scan path: it becomes zero or negative at the scan which corresponds to the end of the character. An algorithm for the computer operation is described, Fig. 7 (not shown).

Patent GB-2006968-A (GB)
Title: Testing rotors of hysteresis motors
IPC: G01R33/14
Filed: 1978-09-21
Abstract: The method of determining the magnetic properties of the rotor of a hysteresis motor by measuring the current in the stator windings when the rotor is held stationary is characterised in that the stator is energised at a frequency (50c/s) considerably lower than the frequency (1,000 c/s) at which it is designed to be energised when the motor is in use. With this method (which clearly also requires that the stator energising voltage be reduced in magnitude by the same proportion as its frequency is reduced) the rotor is still driven completely round its hysteresis loop but eddy currents and reactive loses are reduced. The stator current is therefore more representative of the rotor's hysteresis losses. As shown the stator 4 is energized by a three-phase supply with the rotor 3 held stationary and the average values of the active currents and the voltages are evaluated and displayed. <IMAGE>

Filed: 1980-05-16
Abstract: A method of attaching together an internally threaded member and an externally threaded member, where either   a) the externally threaded member possesses separate right hand and left hand threads, or b) the internally threaded member possesses separate right hand and left hand threads; in both cases, the co-operating threaded member is manufactured with both right hand and left hand threads superimposed on each other.

Patent GB-2065884-A (GB)
Title: Stabilized vortex-shedding flowmeter
IPC: G01F1/32
Filed: 1980-08-07
Abstract: A stabilized vortex-shedding flowmeter for accurately measuring the flow rate of a liquid or gas conducted through a flow tube. The meter includes a front obstacle 11 transversely mounted across the tube with its longitudinal axis normal to the flow axis of the tube. Supported behind the front obstacle and spaced therefrom is a rear obstacle constituted by a pair of parallel beams 13, 14 symmetrically disposed with respect to the flow axis and lying in a plane normal thereto. In operation, as the incoming fluid stream is divided by and flows past the front obstacle, a stagnant zone is created in the gap 12 and vortices are successively detached from the front obstacle. The low pressure produced by each vortex acts to draw the stagnant zone in front of the beam adjacent thereto, the fluid then going around and past the other beam and imposing a drag force thereon. Since the vortices alternate, the drag forces imposed on the beams alternate at a rate proportional to the flow rate of the fluid. A transducer system is provided to sense the alternating activity in the tube and to generate a signal whose frequency is linearly related to the flow rate. <IMAGE>

Abstract: The cap has a skirt (12) having internal projections (14), which snap under a shoulder of a keg spear to hold the cap on the spear. The skirt has a tapering portion (25) extending beyond the projections. The material of the cap is such that there is sufficient resilience for snap-engagement on the spear, but the tapering portion (25) of the skirt is sufficiently brittle to prevent removal of the cap without damage. It is possible to grip the skirt with a tool to turn the cap together with the spear to unscrew the latter. This cannot be done without damage to fracturable projections (20) around the outer periphery of the skirt. <IMAGE>
