Filed: 1941-07-18
Abstract: 575,094. Making electric fuses. ASHCROFT, D. G., SEVER, W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 18, 1941, No. 9093. [Class 83 (ii)] A metal-coated sheet of insulating material for use in making electric fuses is made by spraying a sheet of pasteboard, cardboard, vulcanite, ebonite, presspahn, vulcanized or resin-impregnated fibre, or other insulating on both sides with a molten atomised electricallyconducting metal or alloy, e.g. brass, copper, silver, zinc, nickel, bronze or gun metal. The coatings may be 0.001 to 0.003 of an inch in thickness and be cleaned to assist subsequent soldering. The sheet is then stamped into complementary combs, the tooth tips of which may be rebated to accommodate a resistance bridging wire, and are then coated with deflagrating material. The bridge wires may be soldered to the teeth, but are omitted entirely in making high-tension fuses. The individual teeth are then severed from the comb and leading wires are attached to them, before or after severing, by soldering or spraying with copper &c. The soldering of the bridge wires or leading wires or both may be effected by heating, if the parts of the sheet or comb are precoated with solder by spraying, a thin layer of another metal to improve adhesion being first sprayed on, if desired. The Provisional Specification gives steel, aluminium and phosphor-bronze as other examples of metals suitable for the main sprayed coating and copper and tin as suitable for an intermediate coating between the main coating metal and a solder coating.

Title: Improvements in or relating to sound emitting and receiving devices
IPC: G01S1/72
Filed: 1921-03-24
Abstract: 160,798. Submarine Signal Co., (Assignees of Fay, R. D.). March 26, 1920, [Convention date]. Subaqueous audible signals.-In apparatus for transmitting and receiving sound, particularly for subaqueous signalling, the rigid vibrating plate abutting against the sound-transmitting medium is connected with the vibration producer or detector proper by a longitudinally vibratory member which is substantially unloaded at its other end and the material of which is of substantially equal cross-section throughout. Fig. 2 shows a metallic rod B connected at one end to the diaphragm of a Fessenden oscillator A, and at the other end opened out to form a cone D which is connected to a plate C<1> near its periphery. The plate C<1> is rigid so that all its parts vibrate in phase. Any other connection may be used to secure this result. The cross-section of the material of the cone D is equal to that of the rod B. As shown, the plate C<1> is mounted in an opening in a ship's skin E. It may, however, be secured to the inner surface of the ship's skin, or may be clamped to a rubber diaphragm forming the inner wall of a water-filled chamber, the outer wall of which is formed by the ship's skin. To decrease over all length, the hollow part D of the connection may enclose the remainder, as shown in Fig. 7. For sound reception, a microphone button may replace the oscillator. The dimensions of the rod connection are chosen so that the direct sound wave and the wave reflected from the plate C<1> reinforce one another at the end connected with the oscillator so that the vibration-amplitude is greater than at the plate C<1>. The distance between the point at which the direct and reflected compression waves meet, and the point of maximum vibration-amplitude, should be an odd multiple of the quarter wavelength of the sound in the material of the rod. An effect equivalent to that obtained by variations in the cross-section and length of the rod may be obtained by the use of a weight or weights mounted on, and adjustable along, the rod.

Abstract: 952,689. Kettles. SUNBEAM CORPORATION. March 9, 1962 [March 16, 1961], No. 9194/62. Heading A4A. In a kettle the handle 3 includes a post 7 positioned behind the filling and pouring spout 2 and provided with a passageway 6 for a plunger 5 the upper end of which extends through the top of the post for thumb-operation to open the lid 4 which is pivotally connected to the lower end of the plunger, a spring 9 being provided at the pivot which biases the plunger upwards and the lid to the spout-closing position. The lid rocks and slides on the rim of the spout to seat itself adjustably thereon and is formed by super-posed plates 10, 11 which are spaced at 12 and apertured at 13 to form a whistle. The plate 11 has an extension 14 which passes through an opening 15 in the post and has ears 16 apertured at 17 to receive the hinge pin 8 which also passes through apertures in limbs 28 of the plunger 5. The apertures 17 are larger than the hinge pin to provide lost motion for adjustable seating of the lid. The spring 9 encircles the hinge pin and has one end bearing against a part 29 of the plunger and the other end entering a channel 20 formed in the upper plate 10 of the lid to press nearly centrally on the lower plate 11. The plunger is guided by the engagement of the ends of the pivot pin in grooves 27 in the wall of the passageway 6 which is slightly larger than the plunger and has a step 19 for engagement with a shoulder 18 on the plunger to maintain the lid open against the action of the spring. Upward movement of the plunger is limited by co-operating tapered surfaces 25, 26. The lid, plunger 5 and their pivotal connection form a sub-assembly which is mounted in the handle 3 by sliding the plunger upwards in the passageway in the handle which is secured to the kettle by engagement of a notched bracket 21, screwed to the handle, with a stud 22 fixed to the kettle, the rear of the handle then being secured to the kettle by a stud 23 and stud-receiving member 24.
