Patent GB-2227886-A (GB)
Title: Receiving system
Inventor: WALLINGTON JOHN RICHARD
IPC: H01Q25/02
Filed: 1983-06-06
Abstract: A receiving system uses an array of separate antennas each of which covers a small angle of space. Groups of antennas are connected in a hierarchy so that together they cover a wide angle of space. When a target is passed over from one group e.g. 1, 2, 5, 6 to another e.g 6, 7, 10 & 11 the current group is transformed into a larger group, e.g. 1, 2, 3, 5, 6, 7, 9, 11 embracing the group into which the target will pass. Thus a moving body can be tracked across space covered by different antennas, or sub-groups of antennas without introducing control discontinuities which could result in loss of target. <IMAGE>

Title: Cardiac monitors
Inventor: SPENCER MARIA
IPC: A61B5/363
Filed: 1984-03-20
Abstract: A cardiac monitor includes a heartbeat rate meter (4), an alarm such as a loudspeaker (11), and a comparator (8) which operates the alarm when the heart rate is abnormal, in particular on cardiac arrest. To enable the staff to know how long the cardiac arrest has lasted, the alarm comparator also triggers a timer (10). The timer can be reset manually, or automatically after normal heart rhythm has been re-established. A delay device (12) is provided so that the timer can be reset only after a delay following resuscitation of the patient. Consequently, if the patient relapses soon after resuscitation the timer will measure the total time spent in cardiac arrest.

Title: Guide clamp
Inventor: GRISET NORMAN
IPC: B25B5/16
Filed: 1984-12-10
Abstract: A guide clamp includes a clamping jaw C at one end of a guide bar 20. An opposing jaw S is slidably carried on the guide bar to permit a workpiece to be embraced by the jaws. The guide bar is a flat, rectangular channel member open at the undersurface which engages the workpiece surface. The jaws engage the opposite sides of a workpiece, with the jaw S being lockable in the channel at a jaw-engaging position and with the clamp jaw being shiftable in the channel a short distance by lever action to lock the clamp onto the workpiece. The movable jaw S is locked by means of clips 52 which tend to engage against the inner surface of the channel when the jaw is subjected to pressure, but which can be disengaged by the action of a release carrier 53 which acts via studs 72 and drawbolts 75 to pull the clips 52 out of contact with the channel surface upon relative separation of the carrier 53 and jaw assembly S. Suitable guideways to guide and hold tools, jigs and the like may be provided on the guide bar. <IMAGE>

Title: Preparation of pastilles
Inventor: MALMSTROM KARL THOMAS
IPC: A61K9/20
Filed: 1985-05-03
Abstract: A process for preparing pastilles on the basis of a pastille mass whose main constituent is a consistency agent selected from the group consisting of gum arabic, starch, pectin, agar and mixtures thereof, optionally with the addition of gelatin, and which, in addition to water, further comprises, as required, saccharose, starch syrup, other saccharides, common salt, colouring agents, aromatic agents and/or other flavouring agents is disclosed. The distinctive features of the process reside in that the pastille mass is imparted a dry solids content exceeding 80% by weight, whereupon flavour and colour are adjusted as desired by adequate additions of coloring agents, aromatic agents, citric acid and/or other flavouring agents to the mass, whereupon the resulting batch is mixed in the absence of air before dosed moulding is carried out from a moulding chamber in plastic moulds treated with a release agent, the mass in the moulding chamber and, during the moulding operation, in the moulds being surrounded by air which is humidified with water to a humidity in equilibrium with the vapour pressure of the pastille mass.

Patent GB-2179664-A (GB)
Title: Polymer compositions containing particulate metal filler
Inventor: LEWIS ROBIN JOHN
IPC: C08K3/08
Filed: 1985-08-07
Abstract: A flexible metallic rod or bar comprises high loadings of a particulate metal or metals bound together using an ethylene, vinyl acetate copolymer. The binder system may be substituted in part by compatible elasticisers, extenders, tackifiers or other polymers. The preferred metallic powders used are copper or tungsten or a mixture of both. These components may be intimately mixed by either "dry" compounding techniques at relatively high temperatures or by using suitable solvents such as iii Trichloroethane. After extrusion into its appropriate cross sectional form, the flexible composite is then slit to facilitate the attachment of a fishing line or similar. The slit in this bar is preferably in a spiral configuration and at any angle but the most successful employed is 60' from the axis of the bar.

Title: Containers for flat articles
Inventor: PENNELL JACK FRANK
IPC: G11B33/04
Filed: 1985-12-17
Abstract: A container (10), for example for storing floppy discs or micro-discs, comprises a body, a lid (30) and a pouch (50), moulded from plastics 30 material. The lid (30) and pouch (50) are separate from, but held movably captive on, the main body (12) by respective stud and slot formations (26, 38 and 56, 24). For the lid, the slots (38) require the lid to be moved linearly from its closed position before being tilted rearwardly to an open position, where it remains under its own weight. For the pouch, the slots are arcuate and enable the pouch to pivot forwardly. The open lid then acts as a counterbalance. When the container is closed, there is overlap between the parts of the container, but the external surfaces of the parts are generally flush and give the closed container a rectangular shape. A releasable catch (42, 60) acts between the lid and the pouch. <IMAGE>

Title: Apparatus for analysing transitions in finite state machines
Inventor: LLOYD ALEXANDER HOWARD
IPC: G06K9/62
Filed: 1986-11-11
Abstract: In speech recognition words to be recognized may be represented by finite state machines and recognition is based on analyzing transitions through the machines as an utterance occurs. One value which is then required for each state of each machine in a timescale which is compatible with continuous speech recognition is minimum cumulative distance; that is the smallest of values dependent on reaching one of the states from a starting position, considering all possible paths. In the present invention a specially constructed Viterbi engine is provided for calculating cumulative distances at high speed. Latch circuits holding pointers allow a RAM to be read to provide, for a current machine state, both stored cumulative distances of states with transitions to that state and stored penalties corresponding to the transitions. A logic circuit comprising an ALU finds the cumulative distance for each path as far as the current state, selectes the minimum and adds another penalty dependent on the current state. Thus a minimum cumulative distance is provided for storage and for a speech recognition decision making circuit. The process is repeatedly carried out for each state of each machine. The total number of iterations of the engine in reaching each minimum cumulative distance is also held in the RAM and updated by the logic circuit.
