Patent GB-714201-A (GB)
Abstract: 714,201. Bridge measurements. SOUTHERN UNITED TELEPHONE CABLES, Ltd. April 8, 1953, [April 8, 1952.] No. 8961/52. Class 37. In an automatically balanced bridge or like circuit, a polarized relay is actuated by the out-ofbalance voltage, or a derivative thereof, and the balancing motor is arranged to drive the adjusting element away from the balance position at one stage of a measurement to move the polarized relay to one side position, whereby the motor is reversed, and a part of the stopping circuit prepared. The motor now drives the adjusting element towards the balance position and moves the polarized relay to its other side position thereby completing the setting up of the stopping circuit which is broken by the polarized relay moving to its central-zero position as balance is achieved. The polarized relay is preferably actuated one way or the other in accordance with the direction of the rate of change of current flow therein. As shown, a capacitance X to be measured, a fixed capacitance S and fixed coils N, N form the arms of an A.C. bridge which is balanced by a differential condenser W driven by a continuously running motor 21 through one of two electromagnetic clutches MI, MJ. The bridge out-ofbalance voltage derived inductively by a coil L, is amplified at VI, rectified at V2 and further amplified in a cathode follower stage V3 having an anode supply stabilized by neon tubes 29, 30, the output of V3 being fed in series with a condenser C to the coil 4 of a polarized relay AB which thus. deflects to one side or the other according to whether the condenser C is charging or discharging, i.e. according to whether the out-ofbalance current is increasing or decreasing. To initiate a measurement, a switch O is closed to energize a relay AT, which locks and energizes an unlocking relay MK to release a detent I4, freeing the condenser W for rotation and energizing the clutch MJ to drive the condenser W. Assuming that the direction of drive is away from the balance position, then the error voltage increases and the polarized relay AB closes its right hand contacts 2-3 to energize a slow to operate relay BA which energizes relays AU, BB in turn. Relay AU prepares the stopping circuit at AU 3  and BB reverses the motor drive to the balancing condenser W. As the error voltage now decreases the polarized relay AB closes its left hand contacts I-2 to energize the stopping relay AV. Relay AT immediately falls off but the motor drive,continues in the same direction, until balance is reached, when the polarized relay contact 2 moves to its central position to stop the motor, and revert all relays to normal, at the same time locking the condenser W in the balance position. If at the initiation of a measurement the motor immediately drives the balancing condenser towards the balance position, it continues to drive through the balance position after which stopping is affected as above described.

Title: Producing smoked fish.
IPC: A23B4/023
Filed: 1978-06-30
Abstract: A method of producing smoke- flavoured fish is described in which a smoke flavour composition in powder form comprising salt and a smoke condensate is uniformly dispersed, preferably electrostatically, over the surface of cleaned fish, particularly white fish and the coated fish is then cured until the fish has the desired texture. This generally takes up to an hour at 25- 40 DEG C. The process and intensity of flavour are highly controllable and the resulting fish has been found to retain more of its weight after curing than has been the case with previous smoking methods.

Title: Checking Dimensional Characteristics of Rectangular Blanks
IPC: G01M99/00
Filed: 1978-11-28
Abstract: In apparatus for testing rectangular blanks for dimensional accuracy the blanks (1; 5) travel through the apparatus consecutively to a testing station (4) at which each blank is held stationary during testing and which has: abutments (7; 8; 10) for two edges and testing units (9, 11, 12) for three edges of the blank. Each latter includes pairs of photocells with slits (15, 16) outwardly and inwardly offset with respect to a correct edge position. A faulty edge of a blank results in identical binary output signals occurring from the pair of threshold value switches (17, 18) associated with the corresponding testing unit (9, 11 or 12), such that the resultant output from NAND circuit 20 actuates a sorter 23. A dirt sensing circuit operates on the summed output of pairs of switches (17, 18). A counter registering faulty blanks, can cause stopping of the machine. <IMAGE>

Title: Packing Machine
IPC: B65B5/10
Filed: 1979-04-12
Abstract: A machine for packing objects into boxes comprises a platform comprising two horizontal flaps 15 on which an array of objects 11 to be dropped vertically into a box to form a layer therein is built up. When a complete array is sensed, a plunger 34 moves down to a position above or in contact with the array whereupon the flaps move first down to impart a vertically downward movement to the array and then flip quickly to a vertical position allowing the objects to fall past in their array with the plunger 34 maintaining position. The operation of the flaps and the plunger is controlled by a rotating cam 42 that drives a con-rod connected to the plunger. The cam is profiled so that the plunger is caused to fall by successive decreasing amounts, the decrease being equal to the thickness of one layer of objects. <IMAGE>

Title: Wave Energy Converter
IPC: F03B13/14

Abstract: A device for converting the energy of waves on the surface of water into another more useful form of energy, e.g. electricity, comprises a hollow body having a flat undersurface 1, supported partially immersed such that a narrowing gap is presented to approaching waves, 3. Wave travel compresses the pocket of air 4 which is then delivered, (arrows 7) via apertures 6 to chamber 8, the air in which is thus maintained at a pressure above that of the surrounding atmosphere by a virtually continuous unidirectional flow of air being conveyed to the apertures by successive waves. The air is returned to atmosphere via an energy extraction device such as a turbine or 'windmill'. <IMAGE>
