Abstract: 452,510. Dish - washing machines. GODFREY, G. A., 53, Paxford Road, North Wembley, Middlesex. Feb. 23, 1935, No. 5878. Addition to 385,156. [Class 138 (i)] In a modification of the invention claimed in the parent Specification, the holder supporting the plates is reciprocated by means which is coupled to a hydraulic unit connected in the hydraulic circuit of the sprayers. In the construction shown, a holder e adapted to support a basket containing dishes is mounted in a tank a so as to reciprocate between sprayers d. The holder is reciprocated by pin-and-slot mechanism connecting it to a crank f, which is rotated manually through the medium of a hand-wheel q. The wheel q is also used to drive a pump t by means of which water is drawn from a reservoir and supplied to the sprayers d. The reservoir is divided by a partition w into two compartments x, y containing, respectively, hot washing water and cold rinsing water. Pipes 5, 6 lead from the compartments x, y, respectively, to the suction side of the pump, through a two-way valve 7. Both compartments are in communication, through a two-way valve 4, with a drain 3 in a partition z. The valves 4, 7 are manually controlled so that liquid pumped through the sprayers can be returned to the compartment from which it came. Beneath the holder e is a strainer which is kept clean by scrapers 9 on the base of the holder. The water in the compartment x may be heated by means such as a gas ring or an electric immersion heater, and the temperature of the water may be controlled by a thermostat. The lid may be of the form shown at b<1> in Fig. 2, in which form it is reversible for use as a sink.

Abstract: 1,008,564. Pneumatic separators. ESCHER WYSS A.G. Dec. 18, 1961 [Dec. 21, 1960], No. 45273/61. Heading B2H. In a distributer plate separator in which coarse and fine material, such as cement, is fed through a pipe 19 on to a rotatable distributing plate 9 so that the material is thrown outwardly of the plate 9 into an upwardly directed current of gaseous medium with the result that the coarse material descends and the fine material with the gaseous medium passes into a separating chamber 15, the gaseous medium, partly free from fine material, re-enters a distributing chamber 14, through orifices 17 having guide blades 18, and flows counterwise to the descending coarse material and provision is made for the introduction into the distributing chamber of an additional gas current which is free of dust and so guided as to flow counterwise to the coarse material stream. In the arrangement shown the additional gas current is supplied through a valve control pipe 26 to an annular duct 21 and passes upwardly through an annular gap 22 into the distributing chamber 14. The additional air may also be introduced to the chamber 14 by downwardly directed valve controlled pipe 37. A quantity of gas approximately equal to the quantity of introduced additional gas is removed through an annular gap 24 and a valve control pipe 28. The rotating disc 9 is provided with beating blades 12 and fan blades 13. A diplacement body 33 held in position by ribs 34 reduces the flow cross-section of the coarse material stream and the gas current directed counterwise to such stream. In an alternative arrangement, Fig. 2 (not shown), a rotary displacement body beneath the disc 9 carries a blower impeller at its lower end for the additional gas current to be provided to the separating chamber. In a further embodiment, Fig. 3 (not shown), a blower impeller is mounted directly beneath the disc 9 and is rotatable within a stationary displacement member provided in place of the body 33. The additional gas is supplied by a pipe extending upwardly within the stationary displacement body to the blower and from the blower downwardly within the stationary body and outside the pipe to orifices arranged in the stationary body below the orifices 17.

The hopper 5 is mounted above the feeding apparatus, with pusher heads 23 aligned with slots in the bottom of each compartment and with the troughs 14. A screw 18 driven by gearing 31 moves a carriage 16 along tracks 21, Fig. 4. The pusher heads 23 are pivoted to the carriage 16, so that when the carriage is rapidly retracted they can rotate against springs 25 to slide below the scrap in the container. Scrap pushed along the troughs 14 is melted as it comes within the zone heated by the plasma torch 2, and melted metal falls into the mould 3. Two or more hoppers and charging devices may be arranged round a single mould. The mould 3 is mounted in a casing, and has a dummy bar and grippers for coupling to an ingot discharge device. The furnace has provision for gas circulation and recovery, and a safety pressure control is mounted on one hopper.

Title: Cable fault location
IPC: G01R31/08
Filed: 1971-10-01
Abstract: 1351654 Pulse-echo cable testing systems M A McFERRIN 1 Oct 1971 [1 Oct 1970 9 Aug 1971] 45818/71 Heading H4D In a method of locating a fault in an insulated cable a voltage sufficient to initiate and maintain ionization of insulating material in the fault region is applied to ensure complete breakdown; and a D.C. pulse, having a short rise time and of short or long duration, is applied to the cable concurrently with a point in the region of the peak of the current due to the ionizing voltage, the time interval between transmission of the pulse and reception of the fault reflection pulse being utilized to determine the fault location. Alternatively if the propagation velocity of the pulse is not known the above time interval may be compared to the time interval for reception of a reflecting pulse from the far end of the cable. Ionizing voltage is supplied from 14 and passed to a current limiter 35. A controller 38 closes solenoid switch 37 to apply the ionizing voltage to cable 10 via fuse 33. A current detector 49 signals when the current reaches a level indicating ionization and causes the controller 38 to enable pulse generator 20 to apply a D.C. pulse to the cable. A coupling network 58 and balance network 61 ensure that the pulse is not fed into the receiving circuitry 41. The pulse enters the cable via network 32. The pulse generator also applies a signal to start counter 43, delay 60 ensuring that the count does not start until the pulse has entered the cable. The signal also triggers an oscilloscope 44a. The reflection pulse is passed to switch 31 which may be in the position shown or may be coupled to compare network 39. In the latter position like reflections due to topping &c. from cable 10 and the comparison cable cancel out so that only the fault reflection pulse is passed to the receiver. However the fault reflection pulse may still be distinguished with the switch as shown. The reflection pulse passes through a circuit serving to protect the receiver from over voltages, a high pass filter to eliminate low frequency noise and a pulse shaper. The pulse is applied to counter 43 through gate 42. The gate opens after a predetermined time interval after sending the D.C. pulse in order to ignore early reflections. The count is stopped by the pulse and may be read from display 44. Are - set pulse is also fed to controller 38 thus de-energizing solenoid 36. In addition the reflected pulse may be observed on oscilloscopes 44a. Oscillators 45, 46, 47 are provided so that different cables in each of which the D.C. pulse has a particular velocity may be tested.

Abstract: 1288236 Electrode plates WESTINGHOUSE ELECTRIC CORP 18 Sept 1969 [2 Oct 1968 (3)] 46093/69 Heading H1B An electrode plate for an alkaline battery cell comprises a plaque of intermingled metal fibres joined at their points of contact by metal diffusion bonds and active material substantially uniformly distributed within the plaque. Metal diffusion bonds are limited by definition to those formed by heat only without the application of pressure other than any necessary to ensure physical contact of the fibres. The fibres may be of steel or nickel. Before impregnation with active material, the plaque may be coated with Cu, Ni, Ag, Zn or Cd and/or etched with nitric acid The active material may be introduced by vacuum impregnation with molten metal salt, e.g. Ni(NO 3 ) 2 . 6H 2 O, Cd(NO 3 ) 2 .4H 2 O or Ni(NO 3 ) 2 .6H 2 O: Co(NO 3 ) 2 .6H 2 O. The nitrate may then be converted to hydroxide by electrolysis using the plate as negative electrode in hot NaOH or KOH solution. The plate may then be washed and dried and the impregnationprecipitation-wash-dry cycle repeated until the plaque is sufficiently loaded with active material. To further increase the loading, the plates may be charged, and optionally also discharged, before each loading step. The invention may be used to make Ag, Ni, Zn, Cd and Fe electrodes. Fig. 4 shows a sealed accumulator comprising positive plate 40, negative plate 41, and nylon cloth separators 42. The negative plate may have a greater capacity than the positive plate.
