Filed: 1937-09-18
Abstract: 491,626. Winches. HANSEN, H. S. Sept. 18, 1937, No. 25401. [Classes 78 (ii) and 78 (v)] In trawling-apparatus having brakes for holding the cable drums during towing of the net, the brakes being fitted with pressure applying springs which permit slipping when the strain on the cables exceeds the strain which the brakes are initially set to resist, each brake comprises shoes 18, 19, Fig. 3, pressed against the drum by a spring 29. The lower ends of the shoes have vertical arms 25a, 26a disposed at opposite sides of a fixed abutment 27, the spring 29 being disposed between the arm 25a and a washer 30 on a bolt 28 which the spring surrounds and which passes loosely through the arms 25a, 26a, and the abutment 27, and is held by nuts 31, 32. When the net is let out, a hand wheel on a spindle having screw-threaded connections with the upper ends of the shoes 18, 19 is rotated to compress the spring 29 and set the brake to stand a strain sufficient for fishing. As the weight in the net increases, successive tightenings of the brake bands compress the spring 29 and cause the arms 26a to move further away from the abutments 27. A contact arm 33 attached to the bolt 28 has a wiper contact 39 which moves successively over contacts 50 ... 45, wired respectively to lamps 57 ... 61 and to a buzzer 68 which are connected to one pole of a battery 41, the other pole and the wiper 39 being earthed. The lamps 57 ... 61 are lit successively to indicate the increasing strain and, when the strain on the cables reaches danger point, the wiper 39 engages contact 45 to sound the buzzer 68. In a modification, Fig. 5, the movement of the bolt 28 moves a pump cylinder 75 over a fixed piston on a rod 76 so that fluid is forced up an indicating tube 73. In another modification, the bolt 28 carries a contact slidable on a fixed resistance coil to cause different readings on a voltmeter corresponding to the strains.

According to the invention there is provided a shift register 18, a circuit 19 receiving signals indicating the condition of the bi-stables at the ends of the shift registers and gates P connected as shown. Detailed operation, Figs. 2 and 3.-The number of stages (bi-stables) in register 18 is N and on radar pulse emission there is a shift of one place to the left. As an example assume that the situation is as in Fig. 3 in which a cloud lies between range increments p - 2 and p + 2 in bearing sector A and between increments p - 2 and p + 3 in sector B; and that complete reading of the N columns of the memory is made while the aerial beam sweeps through sector A and similarly for sector B. After the reading of the pth column during the "B" reading cycle the condition of register 18 is as depicted. A pseudo-fixed echo is detected by a circuit 19 of two comparators connected to bi-stables at the extremities of the register; in a comparator an analogue sum signal is compared with a predetermined threshold and controls a gate, e.g. P1. To effect elimination of echoes of high radial velocity clouds or precipitation more comparators are utilized, Fig. 4 (not shown).
