IPC: D06F29/02
Filed: 1948-04-29
Abstract: 648,421. Washing and drying machines. WATSON, F. (Aktiebolaget Elektrolux.). April 29, 1948, No. 11742. [Class 138 (ii)] In a combined washing and drying machine having a single driving motor 35 for actuating a washing member producing movement of the clothes within a washing container 12 and for driving a centrifuging drum 14, the motor 35 is arranged below the drum 14 with its shaft substantially in line with the axis of rotation of the drum, the upper end of the motor shaft being used to drive the drum and the lower end to actuate the washing member through transmission members. The washing member may be an oscillating agitator (not shown) mounted between'a bearing 33 and a driving shaft 34, the 'shaft 34 being driven by the motor through a belt and pulleys 38, 39, a shaft 40 enclosed in a pipe 42, and a gear device 41. The centrifugal drum 14 is driven by the motor 35 through a slidable coupling 36, the upper end of the drum carrying a disc 48 journalled in a bearing 47. This bearing is carried by a cover 45 mounted by hinges 46 on an upper plate 26 of the machine. The washing container may be heated by a gas burner 16 (as shown) or by an electric heating element mounted below a perforated plate 23 in the receptacle. The motor 35 is resiliently mounted on a ring 30 secured to the centrifuge housing 15 by means of vibration damping pads 37 and is readily removable together with one part of the friction coupling 36. A control plate (not shown) is mounted in the front of the machine and has control members for coupling the washing member or the drum 14 with the driving motor 35.

Title: New and improved delay fuse compositions and delay assemblies including same
Inventor: GLASBY JOHN STEPHEN
IPC: H01H85/06
Filed: 1954-04-23
Abstract: 760,360. Delay fuze compositions. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 3, 1955 [April 23, 1954], No. 11772/54. Classes 9 (1) and 9 (2). A delay fuze composition consists of or comprises titanium having a particle size not greater than 60Á, and preferably, a major proportion between 5Áand 35Á, e.g. all passing 300 B.S.S., and at least one oxidizing agent, e.g. lead dioxide, red lead, manganese dioxide, barium peroxide, or potassium permanganate, dichromate, or perchlorate. The ratio of titanium to oxidizing agent may be 60 : 40 to 10 : 90, and the mixture may be corned with an adhesive, e.g. 2¢ per cent. nitrocellulose solution in amyl acetate/amyl alcohol, to make the composition free flowing. The composition may include 10 per cent. inert diluent, e.g. sodium chloride, ferric oxide, magnesium oxide, and calcium fluoride, and other reducing agents, e.g. silicon, boron, aluminium, or magnesium. The composition is pressed into a brass sleeve and assembled as a delay element in a ventless copper electric delay detonator, containing a base charge of 0.55g. tetryl and a charge of 0.35g. of a mixture of lead azide, lead styphnate, and aluminium. The examples show proportions of ingredients for various burning times and quote delay times for assembled detonators. The compositions are subjected to a friction test and a heat test. In the former, a small amount of composition on a mild steel anvil is struck by a mild steel torpedo, having a hemispherical end, which slides down a plane inclined at 70 degrees. The distance of travel and weight of the torpedo are a measure of the sensitivity to friction. In the latter, a small amount of composition is heated in an empty copper tube in a bath of Wood's metal to determine the minimum temperature at which five consecutive samples ignite within 5 seconds.

IPC: G01N27/416
Filed: 1966-03-21
Abstract: 1,068,820. Electrochemical measuring apparatus; liquid level indication. HONEYWELL Inc. March 21, 1966 [April 1, 1965], No. 12238/66. Headings G1H and G1N. In the construction of a reference electrode unit, which is immersed in a liquid, e. g. water in a lake, the sea, to measure it's pH and El values at different depths, means is provided to keep the pressure of the electrolyte, in which the electrode is immersed in the unit, slightly higher than that of the liquid surrounding the unit, in order to keep the electrolyte flowing past the electrode and out into the liquid. In the embodiment, the electrolyte flows into the reference electrode unit 118, Fig. 2, via a conduit 102, from a reservoir 98, one wall of which is a rolling diaphragm 46. A second chamber 96, in communication via apertures 86 in an external fluid tight casing 10, with the liquid under test, also has a similar diaphragm 40 as  one wall. Pistons 50, 56 in contact with the two diaphragms and joined together by a rod 52, transfer changes in pressure in the liquid to the electrolyte, a spring 66 biasing the piston 56 against the diaphragm 46 to increase the pressure of the electrolyte. The electrode 174, in the unit 118, may be made of silver-silver chloride material, the electrolyte being an aqueous solution of potassium chloride saturated with silver chloride, which leaks out of the unit through an aperture 176. A valve connector 116 communicates via a conduit 106 with the unit 118 and reservoir 98 to supply electrolyte when necessary. An indicating unit 286 is also provided in the casing 10 to indicate how much electrolyte there is left in the reservoir. This unit comprises a grooved drum 310 and a rotary cylindrical scale 306 connected together by the shaft 296, supported by a U-shaped member 288. A cord 312 which is secured to the drum, has one end secured to a spring 319 and the other end secured to the rod 52. The rotary scale co-operates with a fixed pointer 322, forming one end of the support 288, to indicate the amount of electrolyte left. pH and Eh probes 178, 186 and a resistance thermometer (194), Fig. 1 (not shown), are also provided extending out of the bottom of the casing 10, the thermometer providing for temperature compensation of the pH and Eh measurements. An electrical cable 202 provides for electrical connection between the probes, reference electrode and thermometer and conventional amplifying and recording circuits, Fig. 3 (not shown). Adjacent the top of the casing, which is provided with a window 266, a transparent crystal-carrying humidity indicator 276 is provided. Also a porous bag (282), Fig. 1 (not shown), is provided carrying a de-humidifying desiccant to absorb condensation. In operation the device is suspended by a cable (258), Fig. (not shown) at different depths in the water.

Abstract: 581,461. Supply systems for space discharge apparatus. GENERAL ELECTRIC CO., Ltd., and WILLOUGHBY, A. H. June 28, 1944, No. 12340. [Class 38 (iv)] A discharge device A (Fig. 1) having no auxiliary starting electrodes is connected across a main supply source B and in parallel with the secondary of a transformer T, preferably in series with spark gap G, whose primary is connected through a switch S to a current source which may be the main supply, the arrangement being such that operation of the said switch produces between the electrodes of the device a voltage pulse capable of initiating the normal operating current, through stabilizing resistor R, coil of contactor C, H.F. choke L and the device A. On D.C.; operation of push button P energizes coil of S through resistor R3 to produce voltage pulse of sufficient amplitude across A to start main discharge current, which then energizes coil of C to short circuit the choke L. In a modified arrangement (Fig. 2), the coil of contactor C is connected across B through normally open contacts of relay D, the coil of which is connected across B at the junction of a resistance R4 and the choke L. Relay contact closes, to operate contactor C to short circuit R4 and L, due to voltage drop across R1 and R4, when the discharge starts. Either arrangement may be used on A.C., resistor R being preferably wholly or partly replaced by a choke and the operation of switch S synchronised with an instant corresponding to suitable values of the current waves in the primary and secondary of the transformer T. Operation of S may be effected by repeated operation of push button D or automatically by the use of a motor driven rotary switch or the rotary switch may be arranged to be spun mechanically by pressure upon a push button. Alternatively S may be operated at the correct instant by means comprising a " backed off " thermionic valve.

The amount of aqueous sodium hydroxide added in step (b) may be 30 to 50% by volume of the mixture from step (a) and preferably contains the stoichiometric amount required to convert the clay to zeolite. The ageing and crystallization steps preferably take place in a closed container and activation of the nodules may be effected by heating at 300‹ to 500‹ C. for ¢to 6 hours. The nodules may be made more attrition resistant by coating with attapulgite and the zeolite may be converted into the calcium form by conventional exchange techniques with CaCl 2  solution.
