Title: Detection of liquid levels - using the hall effect in magneto-resistance probes
IPC: G01F23/68
Filed: 1970-06-10
Abstract: A head of liq. CO2 in a reservoir is used to maintain press in some reactors, and the level of liq. in these reservoirs is detected by means of magneto-resistance probes situated on the outside of the reservoir at given levels. The resistance of these probes varies due to the HAll effect, when a magnet, floating on the surface of the liq. and having a large associated magnetic field (15000 Gauss) parallel to the surface of the liq. is level with them. Each probe is connected to a circuit having either an oscillator, filter and galvanometer or a transistor and current amplifier, from where a signal is relayed so that a light, corresp. to the probe at that level is illuminated.

Title: Thermite welding process for cable conductors - avoids heat cracks by using fall-away intermediate metal piece between conductor ends
IPC: H01R43/02
Filed: 1974-09-04
Abstract: The thermite welding process for cable conductors etc. avoids heat cracks by employing a metal piece between the ends of the conductors requiring welding. The metal piece and the ends are heated to the necessary welding temperature. The metal piece either melts and slips out from between the ends or is allowed to fall out by other means. The conductors ends are then pressed together until the joint solidifies. The metal piece may be of the same material as the conductors, e.g. copper, or of a material of higher melting point, e.g. steel, to delay the ends coming together. The process can also be used for aluminium conductors and for joining aluminium to copper conductors.

Title: Rolling profiles or corrugations into metal sheets - device using two synchronised matching pairs of profiled rolls
IPC: B21D13/04
Filed: 1975-01-31
Abstract: A process and device for rolling equi-distant, transverse, trapezoidal grooves in sheet used e.g. for shaped panels for radiators. The flat sheet is first rolled to produce zones contg. equidistant undulations projecting on one side of the sheet, after which the undeformed regions are rolled to make the finished grooves with projections on the other side of the sheet, a different pass-height being used. The device pref. consists of two pairs of synchronised rolls fitted with matching projections and grooves, no tension being exerted on the first pair of rolls by the second pair. The result is a small area of contact with the radiator thus leaving a large area for heat-transfer. The first pair of rolls produces three undulations at regulat intervals along the sheet using a lower roll with three projections arranged in sets round the periphery at intervals leaving equal lengths of flat sheet between each set of three undulations as shown at the left of the fig. The sheet then passes through the second pair of rolls, the upper roll being fitted with projections contg. a semi-circular recess. The lower roll has equally spaced slots and projections sepd. by flat zones, thus producing the final shape which runs transversely right across the sheet. The short, flat regions produced by the root and face are used to fix the panels to the radiator, thus leaving a large free area.

Title: Sliding door with motor driven panel - has cam operated electric motor for actuating transverse locking bolt
IPC: E05F15/60
Filed: 1975-01-30
Abstract: The sliding door actuated by a linear motor is mounted on a trolley which has on one side guide rollers and support rollers on the other side. This trolley runs on a guiding track fixed in the wall above the door. The rotor shaft of the motor has switching cams for stopping the motor when the necessary rotating position which coincides with the locking cams has been reached. The locking cams are rotated by fixed stops which are held on the door support trolley and the engagement of this stop with the locking cam prevents door displacement. The motor actuates locking members which rotate at right angles to the door travelling direction and the locking cam engages with the locking notches, which are on separate trolleys actuated by the linear motor.
