Title: Improved device for positioning fish in a fish treating machine
IPC: A22C25/12
Filed: 1950-10-16
Abstract: 682,059. Fish, dressing. ARENOC AKTIEBOLAG. Oct. 16, 1950 [Oct. 22, 1949], No. 3827/52. Divided out of 682,034. Class 28 (ii). In pushing fish head first by a rake or pusher against a gauge plate 28 to determine the position at which the head is to be cut off, the plate 28 first offers a resistance to the push until the pusher in sliding along the fish eventually abuts against the branchial arch whereupon the gauge plate 28 yields or swings up against the resistance of a spring 29. When the pusher withdraws from the fish the plate 28 swings down and grips and traps the head firmly against the bottom 50 of the head containing pocket 18. The bottom edge 46 of the plate 28 is normally spaced from the bottom 50 to allow entry of the nose of the fish. The complete machine is as described in Specification 682,034. Specifications 568,214 and 642,897 also are referred to.

Title: Improvements in voltage regulating equipment
IPC: G05F1/52
Filed: 1942-03-28
Abstract: 554,209. Automatic control systems for electricity supply. STANDARD TELEPHONES & CABLES, Ltd., and TARR, J. E. March 28, 1942, No. 4178. Convention date, Oct. 19, 1940. [Class 38 (iv)] Voltage.-To avoid excessive voltage on a load circuit 7 supplied through a series connected regulating triode 8 and having a direct heated cathode, particularly when the source is a thermionic rectifier 3 having also direct heated cathodes and supplying as load an amplifier with indirectly heated cathodes, the grid 9 of the triode is biased almost to cut-off during the warming up period of an indirectly heated control tube 10. A potential divider, comprising a high resistance 17, relatively low resistances 18, 19 and a gas discharge tube 15 or other constant voltage device, is connected across the supply, either on the source or load side of the regulating tube, and the grid 9 and the anode of the control tube 10 are connected through a resistance 16 to the junction of resistances 17, 18 so that the potential drop in the resistance 17 ensures a fixed potential on the grid 9 sufficient to render the tube 8 substantially non-conducting and so prevent excessive voltage on the load circuit. A diode 20 with an indirectly heated cathode is connected across the resistance 17 and heats up in the same time as the cathode of the tube 10, producing an increasing current at resistances 18, 19 which raises the potential of the grid 9 to its normal operating value. Normal plate voltage is also applied to the tube 10 and the regulation proceeds in the normal way according to the setting of the potentiometer. Any suitable delay device may replace the diode 20.

Movable-abutment type; cooling and heating parts; valve-gear; working-fluid supply.-A reversible rotary engine of the type having outwardly-sliding abutments is constructed for use either as a steam or an internal-combustion engine with eight admissions of steam or four explosions per revolution. The rotor 15 has on each side a pair of vanes 16 co-operating with a pair of spring- pressed sliding abutments 5, each of which is periodically withdrawn from the working chamber by an arm 8 on the shaft 6 striking a roller 10 on a pivoted lever 9 connected to the abutment. For use as a steam-engine, steam is admitted for forward or reverse working through one or other of pairs of cam-operated valves 17, the other valves 17 being open to exhaust. When working as an internal-combustion engine, the lower valves 17 remain closed, and valves 49, 50 are opened so that air is drawn in through suction grating 53, cock 51, and pipe 48, and compressed by the next vane through a valve 17 into a reservoir 54. Compressed air trapped between the vanes and the abutment escapes to the atmosphere through valve-controlled relief-pipes 61, 62. After the vane has passed the abutment 5, the next valve 17 admits the carburetted air behind the vane, and ignition takes place, exhaust being effected through pipe 48, cock 51, and outlet 52. The vanes and abutments are provided with passages for circulating cooling-liquid.

Abstract: 766,318. Electric selective signalling systems. STANDARD TELEPHONES & CABLES, Ltd. Feb. 19, 1954 [Feb. 27, 1953], No. 4968/54. Class 40 (1). [Also in Group XIX] A code for use in digital data storage apparatus is such that to a first type of binary bit, say an " 0," there corresponds a change and to the other type, a " 1," there corresponds no change. The code is described as applied to recording on a magnetic drum. Two known methods of recording the data at (a) on a drum are shown together with their idealized output waveforms at (b), (c) and (d), (e) respectively. According to the invention this data would be recorded as shown at (f), (g), where a " 1 " is recorded by maintaining the state of magnetization that existed at the end of the previous time interval and an " 0 " is recorded by changing the state of magnetization that existed at the end of the previous time interval. It will be seen that the use of this code by itself enables twice as much data to be recorded in a given space without modifying the frequency handling ability of the head or increasing the " change of magnetization " density. This code has the disadvantage, however, that as a long run of consecutive " 1's " results in a long run of no change, surface imperfections may cause spurious pulses to appear. Several ways of overcoming this are discussed, one of which, shown at (i), (j) is to have between every group of four digits, " blanks " during which a change always occurs. Specification 766,317 is referred to.
