Title: Improvements in or relating to electrical switch gear
IPC: H01H9/00
Filed: 1962-03-16
Abstract: 969,669. Mechanical switches, without quickaction. E. W. PARRISH. Jan. 23, 1963 [March 16, 1962], No. 10240/62. Heading H2B. An electric switch, preferably for isolating the battery from the electrical system of a vehicle carrying petrol &c., comprises at least two pairs of stationary contacts 1, 2, biased by springs 4 located in insulating pads 5 and a contact barrel 10 of insulating material with contact strips 12 on two faces. Initially the pairs of contacts 1, 2 are bridged by the contact strips 12, but on rotation of the barrel 10, the pairs of contacts 1, 2 and strips 12 are isolated. Terminals 7 of the contacts are aligned with holes 14 either in the base or sides of the casing. An earth testing contact 15 is provided for engagement with the contact 2 so that contact is broken when the barrel is rotated, thus indicating a fault by means of the vehicle's components. In another embodiment, Fig. 11 (not shown), the contact 15 is replaced by a forked blade contact movable by an insulating member, located between the switch contact and biasing spring, when the barrel is rotated. The barrel 10 may also be modified to have one or more contact studs extending through the barrel between the sides without the strips 12 so that the switch may be connected as a doublepole circuit breaker, Fig. 5 (not shown), may connect two batteries in parallel or series, Figs. 6, 7 (not shown), may be a reversing switch, Fig. 8 (not shown), or a change-over switch, Fig. 9 (not shown).

Abstract: 755,764. Cartridge-operated bit or nail firing tools; projectiles for industrial tools. BOURNER & CO. (ENGINEERS), Ltd., F. H., and BOURNER, F. H. April 7, 1954 [April 10, 1953], No. 10257/54. Divided out of 9872/53. Classes 9(.1) and 119 In a cartridge-operated tool for firing bits or nails into hard material, a plunger 52, Fig. 1, in the barrel 10 has temporarily attached to it the bit or nail and a stop 61 of hard steel provided with a cushioning washer 63 of mild steel is located at the end of the barrel, the stop 61 and washer 63 having apertures which permit the passage of the bit or nail but not the plunger 52. As shown in Fig. 1, the washer 63 engages in a chamfered recess 66 of the stop 61. In an alternative form, Fig. 3, the washer 63 rests on the inner face of the stop 61 and is held by rubber cement 67. The apertures in the washer and stop permit the passage of a reduced end portion 53 (Fig. 2, not shown) of the plunger 52 to which the head 51 of the bit or nail is temporarily attached by a cap 55 or by engagement of the head 51 in a recess in the reduced portion 53.

Abstract: 1376433 Diaphragm vibrators R A ABSALOM 4 Nov 1971 [7 Nov 1970 20 April 1971] 53087/70 and 10310/71 Heading G5J [Also in Division H3] An electric sound-producing device comprises a resilient diaphragm of ferromagnetic material which is made to vibrate under the action of an electromagnet supplied from an electronic oscillator with short duration pulses at a repetition frequency substantially less than the natural frequency of the diaphragm. The diaphragm 15, Fig. 1, contains a central flat portion 16 and an external rib 19 which clips into an internal groove in the cap 11. The body 10 and cap 11 can be adjusted to give the required airgap between the flat portion 16 of the diaphragm and the electromagnet core 22 by means of abutments 12 on the body and inclined ramp faces in the cap. In alternative embodiments the cap can be replaced by an acoustic resonator or by a horn. Each embodiment of the device can employ any one of four circuits to produce the current waveform, either in the form of a continuous output or, if controlled by a multivibrator or sawtooth pulse generator, in the form of an intermittent output in the coil windings, said windings forming an integral part of the oscillator circuit.

Title: Improved manufacture of ethyl alcohol from sulphovinic acid
IPC: C07C29/06
Filed: 1923-04-17
Abstract: Ethyl alcohol is obtained from sulphovinic acid by treatment with ammonia, which fixes the sulphuric acid content with the evolution of sufficient heat to effect the distillation of the alcohol without the application of external heat.  The ammonia is used either in the gaseous condition or in the form of a solution; ammonium sulphate is obtained as a by-product.  According to the example, a stream of ammonia gas is conducted into sulphovinic acid or sulphuric acid containing sulphovinic acid: the alcohol distils off to a dephlegmator and is condensed; ammonium sulphate settles out or remains dissolved in the ammonia-saturation vessel. The operation may be carried out at normal or reduced pressure.  The Specification as open to inspection under Sect. 91 (3) (a) describes also the treatment of the sulphovinic acid with any reagent which fixes the sulphuric acid content with evolution of heat.  This subject-matter does not appear in the Specification as accepted.ALSO:In the production of ethyl alcohol from sulphovinic acid by treatment with gaseous ammonia or ammonia solutions to fix the sulphuric acid content, ammonium sulphate is obtained as a by-product.

IPC: G01N25/36
Filed: 1921-04-12
Abstract: 182,918. Dickinson, H., and Dickinson, R. Y. April 12, 1921. Alarms operated by evaporation of liquids.-An instrument for detecting smoke in the atmosphere comprises expansion chambers operated by the heat from a flame and adapted to close an electric circuit, thus sounding an alarm and operating an indicator, on a sudden fall in temperature, such as would occur owing to the presence of smoke around the flame. The expansion chambers 11, 12, Fig. 3, each formed from a thin flattened tube sealed at both ends, are mounted on a base 13, Figs. 1 and 3, in a slide 14 mounted on a bracket 15 secured to a casing 1. The chambers 11, 12 each contain a liquid of different volatility, or they may be of different shape or thickness. The chamber 11 is slightly larger than the chamber 12 and carries an insulating- pin 16 engaging the bent end 17 of a rod 18 mounted so as to slide in a guide 19. A plate 20 on the rod 18 bears against the guide 19, and a finger 21 attached to the rod 18 contacts with the chamber 12 when a differential movement of the chambers 11, 12 occurs owing to a rapid change in temperature. The casing 1 has an aperture 3 in a domed base 2 and a gas or oil jet is mounted in a chimney 4 over the aperture 3. A domed cover 8 is supported from the top of the casing 1 by brackets so as to leave an annular outlet. The base 13 is electrically connected to a terminal 23 and an alarm 27, Fig. 3, and the guide 19 is electrically connected to a terminal 25, a battery 29, and the alarm 27. The circuit is completed when the finger 21 contacts with the chamber 12.

Abstract: 791,417. Extruding. SCHLOEMANN AKT.- GES. April 10; 1956 [April 16, 1955], No. 10866/56. Class 83 (4). An extrusion press, preferably for making steel tubes, has its extrusion die 4 and die holder 3 carried by a rotatable arm 15 mounted on an axis parallel with the extrusion axis, said arm being also displaceable in the direction of extrusion to permit the extruded product to be severed from the discard. The arm 15 carries a die and die holder at each of its extremities whereby one of them may be changed whilst the other is in operation. The arm is mounted on a shaft 11 slidably connected by splines to a hollow shaft 12 rotatably mounted in the press bolster 1 and driven by a worm gear 34. A pressure member 2 for the die is carried by a second rotatable arm 14 mounted directly on the hollow shaft 12, Fig. 2, whereby it is rotatable with the die, out of the extrusion position. For extruding a steel tube, a heated steel billet is inserted in the container bore'6, a mandrel 33 is pressed through the billet, and the latter is then extruded between the mandrel and die 4 by the press ram 8 having a pressing disc 7. After extrusion the container 5 is retracted, Fig. 2, and the arm 15 carrying the die is. moved with the container-by means. of pressure fluid admitted to a cylinder 37 containing a piston 36 connected by a rod 35 to the solid shaft 11. A saw blade 16a then severs the extruded tube 10 from the discard 9 which adheres to the pressing disc 7. The arm 15 and its die is then moved to the left by reversing the fluid pressure in the cylinder 37, and the two arms 14, 15 are rotated to move the die and die holder away from the container bore whereupon the discard 9 and pressing disc 7 are ejected by the ram 8. The die parts 2, 3, 4 are then cooled and cleaned whilst a new billet is inserted in the container. In another embodiment, Figs. 4, 5 (not shown), one end of the arm 15 is shaped to receive the discard ejected from the container and convey it to a shoot.
