Title: Method and apparatus for forming heat treated blown thermoplastic articles
IPC: B29C71/02
Filed: 1979-06-11
Abstract: A method and apparatus are disclosed for developing a strain crystallized morphology in blown bottles 25 of thermoplastic material by a heat treatment process subsequent to a blow molding operation. In a first embodiment, the blow mold 12 itself includes means for differentially heating the blown article along its length so that only those portions which have been significantly molecularly oriented are heat-treated. In a second embodiment, separate mold-shaped members are mounted adjacent the blow mold to receive the blown articles to apply the desired heat treatment process. In the method, an essentially amorphous polyethylene terephthalate parison is expanded in a blow molding operation at a temperature conducive to molecular orientation and strain induced crystallization. Then, the highly molecularly oriented bottle portions are heat treated to develop crystalline growth, while other non-molecularly oriented bottle portons may be simultaneously cooled. <IMAGE>
Patent GB-2031363-A (GB)
Title: Crane Safety System
IPC: B66D1/54
Filed: 1979-10-15
Abstract: A crane safety system by which emergency braking action can be initiated in response to angular mismatch between two hoist barrels BL, BR or other components of the crane hoist drive system. Angular mismatch is detected by two detectors L, R driven by respective components. Each detector comprises electrical contacts or photoelectric devices which are changed from one condition to another by rotation of an assembly in the detector. So long as the components preserve angular synchronism the electric devices maintain electrical continuity in a control circuit. If angular mis-match occurs because of excessive angular velocity or angular acceleration or a combination of both on the part of either of the components, that continuity is broken and the circuit initiates emergency braking. Response is very rapid and a wide range of eventualities is catered for. <IMAGE>

Title: Electrochemical sensor and method of calibration thereof
IPC: G01N27/48
Filed: 1979-09-20
Abstract: A sensor, and a method of calibrating a sensor for measuring the partial pressure of gas in a liquid, are provided. The sensor (1) comprises two electrodes (2) and (5) mounted on a support member (3) and covered by a moistenable membrane (6) which is permeable to gas, and means (9) for retaining a liquid around the moistenable membrane. The method comprises obtaining two sets of values of current and partial pressure of a gas. The first set of values is obtained by immersing the sensor (1) in a liquid in which the partial pressure of the gas has a first known value and then applying a voltage to the sensor (1) to obtain a first current value corresponding to the first partial pressure of the gas. The sensor (1) is then removed from the liquid and, with some liquid remaining on the sensor, the same voltage is applied to the sensor until the partial pressure of the gas has fallen to a second known, minimum value whereupon a second value of the current for the second minimum value of the partial pressure of the gas is taken. A rectilinear calibration curve of current versus partial pressure is then made. The method requires only one liquid which has a known partial pressure of the gas. <IMAGE>

Title: Data processing system
IPC: G06F13/16
Filed: 1980-03-12
Abstract: In a data processing system central processor units (10 and 10A), input/ output units (12), memory units (11) and secondary storage units (24, 25, and 26, 27) are interconnected by a bus (14). When one of the units, for example the processor unit (10), is to transfer information to a second unit, for example the controller (20) of the memory units (11) over the bus (14), the first unit, to prevent other units gaining access to the bus, generates a first signal onto a line in the bus (14) for a predetermined number of clock pulses, e.g. one cycle conflicting requests for bus access being resolved by priority arrangements. The second unit then takes over generation of the first signal on the bus line after the predetermined number of clock pulses up to the end of the transfer. <IMAGE>

Title: Pressure-resistant Cable Strength Member
IPC: G02B6/44
Filed: 1981-01-13
Abstract: A communication cable to be used in a hostile environment needs to be protected from that environment, this being especially the case for an optical fibre cable for use in submarine conditions. To provide such protection, an optical fibre package, which may include one or more optical fibres is layed within a hollow tubular member which acts as a pressure-resistant and load-carrying member. This member is made from at least one layer of stranded wires, which layer may include alternate round cross-section wires (1) and waisted cross-section wires (2). The fibre package is in the central tunnel (3), and may be of such length relative to the tubular member as to be slack. It is noted that other cross-sections for the wires can be used as long as each layer is a complete tube, and that adjacent wire layers can be wound helically with opposite lays. <IMAGE>

Title: Reeds
IPC: D03D49/62
Filed: 1982-04-22
Abstract: A reed comprises first (7) and second (13) dents which each comprise two limbs (8, 9; 14, 15) and a connecting portion connecting these limbs and which in the connecting portion are each provided with a recess (12, 16) for forming a half- open guide channel for the weft thread, this channel extending over the maximum weaving width. The recesses (12, 16) are in weftwise alignment with one another, and the limbs (8, 9; 14, 15) of the first and second dents (7, 13) are offset relatively to one another warpwise. As a result the warp threads (5, 6) are guided in a closely spaced pitch when the weft is beaten-up and in a more broadly spaced pitch when the weaving shed is formed and are thus dealt with considerably carefully. Lumps in the warp threads (5, 6) also have less troublesome effects. Other embodiments with three sets of dents and an embodiment where the dents (7) have no recesses are described. <IMAGE>
