Title: Improvements in and relating to echo sounding for use in deep sea fishing
IPC: G01S15/10
Filed: 1965-05-05
Abstract: 1,101,755. Echo sounding. ATLAS-WERKE A.G. 5 May, 1965 [5 May, 1964], No. 18975/65. Heading H4D. In an ultrasonic echo-sounding method for indicating fish near the sea-bed, a pair of pulses of the same carrier frequency, the first pulse being weaker than the second pulse, is transmitted in each sounding period, and the seabed echo of the first pulse initiates the movement of the pen of a chart recorder or the luminous spot of a cathode ray tube so as to record the fish echoes and sea-bed echo of the second pulse. The interval between the two transmitted pulses, which is small compared with the sounding period, is so chosen with regard to the sea depth, the angular width of the conical sounding beam, and the distance between the fish and the sea-bed, that the echoes produced by the second pulse arrive at the echo sounder receiver after the reverberation of the sea-bed echo of the first pulse has died away at the receiver and before the second sea-bed echo of the first pulse arrives at the receiver. Numerical examples of the pulse periods and echo times are given for a sounding beam of semi-apex angle 15 degrees.

Abstract: 1435434 Retractive switches BURROUGHS CORP 2 May 1974 [1 June 1973] 19225/74 Heading H1N In a switch assembly in which conductive leads on the underside of a flexible diaphragm 22, Fig. 2, are deflected into engagement with contacts 16 on a rigid base 14, the actuator 54 is coupled to the flexible diaphragm through a compression coil spring 42 while resistance to movement of the actuator 54 is increased by a concentric coil spring 44 engaged between a flange 56 of the actuator 54 and a stationary support 38. The actuating spring 42 has a region 72 of close coils and a region 74 of open coils whereby two spring rates are obtained so that a firm application of the contacts is obtained to avoid contact bounce. Conical surfaces of the outer flange 56 and of an internal projection 70 support the springs 42, 44 against lateral deflection when compressed. The spring 42 acts on the diaphragm 22 through flexured member 28 made of thicker more rigid material than the diaphragm 22 but having slits 34 around the central region to render it flexible. The member 28 has a pair of projections 76, Fig. 7, on its underside adapted to co-operate with a pair of parallel contacts 24. The projections 76 are arcuate to permit the member 28 to tilt freely by rolling. Universal tilting is obtained, by providing only a narrow contact region 78 between the member 28 and the spring 42. The parallel contacts 24 may also be separated in the region of engagement to form pairs of axially aligned contacts 90, Fig. 11, whereby initial contact is made at the pointed ends with high pressure until the contact area is increased. A button 48 may be releasably attached to the actuator 54 by means of flexible prongs 64 engageable in a notched recess 66, 68.

Abstract: 608,133. Transformers. BENDIX AVIATION CORPORATION. July 31, 1945, No. 19679. [Convention date, July 4, 1944. [Class 38 (ii)] Also in Group XXVII] In a combined shielded sparking-plug and transformer the outer end of the insulated central electrode assembly is received in a recess in or in the hollow interior of a rigid insulating member on the exterior of which the primary and secondary windings of the transformer are mounted so as to surround or extend lengthwise over the outer part of said electrode assembly. The invention is shown as applied to a sparking-plug of the type described in Specification 586,014, [Group XXVII],. referred to. In this sparking-plug a ceramic insulator 18 carries a central electrode 15 which is held in place by cement 20 in a bore 16 in the insulator. The insulator is fixed to the body portion 10 of the plug by means of a tapered sleeve 23 of soft material such as copper. At the upper end of the bore 16 a terminal 21 is also held in place by cement. Extending from the body 10 of the plug is a radio screening barrel 24 which may be integral with or attached to the body. Within the barrel is arranged a transformer 30, 32. The secondary 30 of the transformer is wound on an insulator 26 having a hollow interior 27 which surrounds the upper end of the insulator 18. Included in the hollow portion 27 are also a laminated metallic core 27 and a core portion 29 comprising turns of magnetic sheet material. The primary 32 is separated from the secondary 30 by a layer of insulating material 31. A split sleeve 40 of magnetic material surrounds the primary and is insulated from this winding and the screening barrel. The sleeve is split in the direction of the axis of the sparking-plug to reduce losses due to eddy currents around the transformer. One end of the primary is connected to a terminal 35 in the insulator 26 and to one end of the secondary. The other end of the secondary is connected to the terminal 21 associated with the central electrode 15 and the other end of the primary is connected to earth by way of the body portion of the plug. The metallic core member 29 may be coated with a thin layer of insulation such as enamel. The terminal 21 may be of magnetic material. The insulating layers may be of fabric made of fine glass fibres and impregnated with silicon. The whole of the interior of the barrel may be sealed by means of an insulating compound such as polymerized cashew-nut-shell oil and a drying agent as described in Specification 549,580, [Group XXVII], also is referred to. The whole assembly of the insulator and transformer is held in place with a spring 39 between the terminal 21 and core member 28 under compression by means of an adaptor 42 attached to the barrel by turning over the upper edge of the barrel and soldering. Member 42 serves for the attachment of a coupling nut for a screened cable supplying current to the primary winding.
