Patent GB-2134669-A (GB)
Title: Rolling mill operation
Inventor: BIRNAND PETER WILLIAM
IPC: B21B37/18
Filed: 1983-02-08
Abstract: In a method of operating a rolling mill, the control signal which is used to adjust the roll gap of the mill in the sense to produce the required exit gauge of the strip being rolled is modified by a correlation coefficient so as to cause an exit gauge error caused by an entry gauge error to be reduced substantially to zero. The coefficient is produced by correlating the output gauge of the strip with a twice delayed signal representing the ingoing strip measured upstream of the rolling mill. <IMAGE>

Patent GB-2147979-A (GB)
Title: Liquid heater
Inventor: CHAN KWOK MAN
IPC: F24H1/20
Filed: 1984-05-16
Abstract: The heater comprises a tank 10 containing an electric heater 16. The tank 10 is charged with water through a valve 32 controlled by a float 28 which maintains a predetermined water level. A vent opening 30 maintains the water in the tank at atmospheric pressure. The charge of water is maintained at an elevated temperature by a heater 16 having a thermostat 40. Cold water is fed through an inlet 21 to a coil 18 in the tank 10 and is heated by the water in the tank 10 as it flows through the coil to an outlet 23. In a modified heater (Figs. 7 to 9) the float 28 and valve 32 are replaced by an electric level sensor 160 which operates a solenoid valve 166. The sensor 160 controls LEDs 170 which indicate when the heater is on, off, filling or overheating and when the water level is too high or too low. <IMAGE>

Title: Spray damper
Inventor: STAHLE WALTER
IPC: F02M65/00
Filed: 1984-07-05
Abstract: A spray-damping device simple and economical to construct and intended for an injection-pump test stand is proposed. The injection nozzle (4) fastened in a threaded piece (5) directs its nozzle jet onto the end face of a screw plug. Spray-damping is achieved because threads having different thread pitches and pitch directions are provided on the threaded piece and the screw plug at the same height. As a result, the nozzle jet is stabilized in a simple and effective way. This makes it possible to read off the measuring result quickly.   <IMAGE>
Patent GB-2143945-A (GB)
Title: Frost sensor
Inventor: NICHOLSON FREDERICK JAMES
IPC: G01B11/06
Filed: 1984-07-25
Abstract: A frost sensor for remote sensing of the build-up of frost 18 on a cooling fin 8 comprises an infra-red emitter 1 and an infra red sensor 2, preferably matched spectrally. The emitter illuminates a wide solid angle 5 of at least 45 DEG  and preferably 60 DEG , and the sensor is sensitive to a similarly wide angle. The emitter and sensor are mounted so as to be directed generally towards the edge of a cooling fin 8 on which the build-up of frost 18 is to be sensed, and at a distance therefrom such that the areas covered respectively by the emitter and sensor overlap the maximum normal width of frost deposit on the fin. As the frost deposit thickens, the area from which infra-red light is reflected increases, and so the infra-red received by the sensor similarly increases. The output of the sensor can initiate defrost automatically at any desired frost level. <IMAGE>

Patent GB-2152675-A (GB)
Title: In process measurement of metallic coating layer thickness
Inventor: PRATT ANTHONY LIONEL
IPC: G01B7/06
Filed: 1984-12-14
Abstract: High strength nickel alloy turbine components (2) are commonly protected from the effects of temperature oxidation and corrosion by a thin surface layer of aluminide. One method of applying such a layer is by the pulse aluminising process, wherein components (2) in a reduced-pressure argon atmosphere are exposed to aluminium-rich vapour from heated aluminide powder (10). A major problem with this and any other metallic deposition process resides in determining accurately how thick a coating layer has been applied. This invention provides a means of determining the thickness of a coating by exposing a coil of wire (16) to the aluminium rich vapour such that it is similarly coated. The resistance of the wire changes as the coating layer is increased in proportion to its cross-sectional area and it is this property that is monitored with a multimeter or similar instrument. The changes in resistance of the wire can easily be related to the thickness of the coating layer and hence accurate in situ measurements can be made of the coating thickness. <IMAGE>

Title: Separation of a reinforcing member from a multi-conductor electric cable
Inventor: DAVIES STEPHEN MICHAEL
IPC: B25B27/00
Filed: 1986-01-20
Abstract: In a method of separating the flexible reinforcing member from a multi-conductor cable of trefoil cross-section, two pivotally inter-connected arms 11 of a spring-loaded pincer-like piercing tool are applied around the hole of the trefoil in which the reinforcing member is encapsulated at a position intermediate of the ends of the cable. Each arm 11 has an inwardly facing surface 12 of a shape such that the two arms will encompass the lobe and each of the arms has at its free end a tooth or teeth 14 which will interengage with the tooth or teeth at the free end of the other arm. The free ends of the two arms are urged towards one another against the action of the spring to cause the teeth to bite through the web joining the lobe to the other lobes of the trefoil-shaped plastics body of the cable. The web is split lengthwise of the cable to a sufficient extent to separate from the cable a length of reinforcing member. <IMAGE>
