Title: Improvements relating to the dressing of fish
Inventor: SCHLICHTING KARL FRIEDRICH
IPC: A22C25/00
Filed: 1955-10-31
Abstract: 822,263. Fish, heading and tailing. BAADER, R. G. T. Oct. 31, 1955, No. 31110/55. Class 28 (2). Fish have their heads and tails cut off at positions in proportion to their size (thickness) by manually pushing each fish in one of holders 3 with its belly leading until its snout protrudes between two guide-rods 12, so that moving conveyer chains 1 carrying the holders convey the fish broadside on to a head cutting disc knife 15. The holders 3 are inclined to the conveyer so that a skew cut is made through the neck. The position of the cut is varied in accordance with the thickness of the fish head by a pivoted feeler 28 which rocks a bell-crank 53 carrying a block 27 in inclined guides 26, which being inclined swing sideways a sleeve 52 carrying the shaft 16 of the knife 15, thus adjusting the knife to an economical cut-off. During the cut the neck slides on and is supported on the inclined top surface 4 of a fixed bar 14. The back of the neck is supported by a lug 13 attached to the conveyer bar 2, Fig. 5. The tail fin is then cut off by a disc knife 33, Fig. 5, the fish-holder 3 being tilted by the roller 5 rolling over a cam surface 9 whereby the fish slides down by gravity so that the tail protrudes and is supported by a support 56 with a slot 57 to accommodate the knife 33. The knife 33 and its mounting frame part 40 can be rocked sideways to position the cut by a rocking lever 42 pivoted about 43 and rocked by hand or cam.
Patent GB-950471-A (GB)
Title: Improvements in or relating to pulse code modulation encoders
IPC: H04J3/10
Filed: 1960-09-09
Abstract: 950,471. Pulse code modulation systems. WESTERN ELECTRIC CO. Inc. Sept. 9, 1960 [Oct. 2, 1959], No. 31131/60. Heading H4L. A coder for transforming a signal amplitude sample into a code group of marks and spaces occupying successive time slots comprises means for applying the sample to the encoder for a period of time less than n time slots, a series of n encoding stages for determining and storing the code group, and means for reading out the stored code group so that a mark or space of the code group appears in each of the n time slots. The rest period for the encoding stages is increased with consequent reduction of crosstalk and simplification of the input circuit. As shown, in a sequential type seven digit binary encoder, the signal samples (a) are supplied to terminal 71 during the first four time slots of the encoding cycle. Pulses D1 to D8, applied to lines 75 to 78 respectively, control the encoder and the read out, pulse D1 being applied during the first half of the first time slot, D2 being applied during the second half of the first time slot, and so on, and during the fifth to the eighth time slot the pulses are repeated in the same order. Pulse D1 sets the bi-stable device 83 so that a voltage appears at its " odd " output terminal which together with the pulse D1 actuates the AND gate 10 whose output sets the bi-stable device 50. The resistors 60 to 66 associated with the bi-stable devices 50 to 56 are weighted in binary fashion. If the input sample is greater than 64 units, the device 50 remains set during the remainder of the encoding cycle since under this condition there is no output from the amplifier 70. If it is less than 64 units an output from the amplifier 70 combines with pulse D2 to produce an output from AND gate 20 which via OR gate 40 resets the device 50. Pulse D2 and the " odd " output of device 83 actuate the AND gate 11 to set the bi-stable device 51 and the comparison is repeated until, at the end of the first four time slots, the devices 50 to 56 have assumed states constituting a binary representation of the signal sample. The occurrence of pulse D2 and the " odd " output of device 83 and the AND gate 30 during the first time slot causes the state of the bi-stable device 50 to appear at the output terminal 84, (d) Fig. 2, AND gates 31 to 33 being actuated in a similar manner by the occurrence of pulses D4, D6 and D8, in the second, third and fourth time slots. During the fifth time slot pulse D1 causes the bi-stable device 83 to change state and produce an " even " output potential, and during the fifth, sixth and seventh time slots the outputs of bi-stable devices 54, 55, 56 are read out in a similar manner via AND gates 34, 35, 36 respectively. During the last half of the eighth time slot pulse D8 actuates the AND gate 17 which via OR gates 40 to 45 resets the bi-stable devices 50 to 56.

Title: Improvements in elastic fabric and method of making same
IPC: D03D15/56
Filed: 1935-11-13
Abstract: 448,669. Elastic fabrics ; coated fabrics; compound fabrics. INTERNATIONAL LATEX PROCESSES, Ltd., 10, Lefebvre Street, St. Peter Port, Guernsey. Nov. 13, 1935, No. 31379. Convention date, Dec. 18, 1934. [Class 140] Elastic fabrics are produced by condensing a fabric, i.e. reducing its dimension in one direction while substantially unextended in any direction and without planar distortion, and depositing rubber on to the condensed fabric so as to maintain it normally in condensed condition. As shown, a rubber belt 10 is extended lengthwise between rolls 11, 16 and coated with adhesive e.g. glue, at 13, fabric 18 being fed into the nip of the rolls 16 and passing with the belt through rolls 20, 21, 22 running at progressively slower speeds whereby the belt relaxes and the fabric adhered thereto is condensed. Rubber-containing fluid, e.g. latex is then applied by a spraying-device 25 or spreader and the rubber is deposited upon the fabric by a coagulant or by passage through a drier 27. After passing through a steam chest 29, to soften the adhesive, the fabric is separated from the belt and passed through a washer 31, drier and vulcanizer 32 to a roll 33, the belt passing through a washer 34 and drier 35 to the rolls 11. The fabric may be plied before or after winding. The steam chest 29 may be omitted. Adhesives other than glue may be employed e.g. shellac, copal, cellulose compounds &c. dissolved in non-rubber solvents. Woven, knitted, and netted fabrics, composed entirely of textile thread or containing bare or rubber-covered threads, may be employed. Vulcanized latex may be used, but preferably vulcanizable latex is employed, and where fabrics are to be doubled or plied, vulcanization is not allowed to reach completion before plying. The coating of rubber may be a light deposit to preserve porosity of the fabric, or may be a heavy impermeable film. The rubber surface of a single or plied fabric may be flocked. Where it is desired to condense a fabric widthwise, cut lengths of fabric equal to the width of the belt 10 are applied transversely thereto ; alternatively the belt is stretched laterally by a tenter, with or without longitudinal stretch, and allowed to relax after application of the adhesive and fabric. The adhesive may be applied in a pattern, e.g. by spaced rollers or a grooved or notched knife or bar to produce fabrics having a puckered appearance. A non-elastic belt of rubber, metal &c. may be employed and the fabric condensed thereon by a faster-running roll. In a further modification, fabric treated with rubber-containing fluid is sandwiched between two stretched belts the tensions on which are released before or while depositing the rubber e.g. by drying.
