Two or more laundry washing-machines are arranged so that one machine can be isolated for unloading and loading, the only flow of liquid between two or more machines being when these machines are temporarily interconnected. Each machine is connected to a tank through which the liquid passes during circulation through that machine, each tank being divided into two compartments E, F connected by a valve J. Circulation is effected by means of paddles C on a washing drum A which rotates in a casing B, liquid flowing to compartment E and returning from compartment F. Compartment E has a drain valve G or its equivalent and a transfer valve H connecting it to a manifold L common to both or all machines. The valves G, H, J, and cold/cold and hot water supply valves are automatically controlled by a timer. In Fig. 4 (not shown), two machines are coupled together for washing and rinsing, steam being used for heating. Figs. 6 to 10 (not shown), illustrate the use of three machines coupled together, with heating by hot water. As seen in Fig. 7 (not shown), the drain valve comprises a movable standpipe (P) which serves also as an overflow and the transfer valve (connecting the circulating tank to the common manifold) is replaced by a removable stand pipe (Q) containing a non-return valve (R).

Abstract: 1,031,459. Semi-conductor monostable circuits. JOSEPH LUCAS (INDUSTRIES) Ltd. Sept. 18, 1962 [Sept. 20, 1961], No. 33636/61. Heading H3T. [Also in Division G4] A pulse-counting circuit comprises a diode pump circuit connected to a source of input pulses, a four-layer diode arranged to breakdown after the pump circuit has received a predetermined number of input pulses and which is connected to a semi-conductor controlled rectifier so as to render the latter conducting, and means for switching off the controlled rectifier after it has been conducting for a predetermined period of time. As shown in the Figure, when a predetermined number of pulses have been applied via terminal 3 to diode pump circuit 8, 9, 10, 11 the voltage across capacitor 8 is sufficient to cause fourlayer diode 7 to break down. A pulse then passes to the gate electrode of rectifier 5 so as to switch the latter on and cause a current to flow through load 4. Capacitor 13 is then charged until four-layer diode 15 breaks down at which point a pulse is fed through capacitor 16 to switch off the rectifier 5, which is of the type which may be switched off by the application of a suitable pulse to its gate electrode as described in the Specification, the length of conduction period being determined by variable resistor 12.

Abstract: 341,594. Making bricks, tiles, &c. WANKLIN, A., 1, Claremont Avenue, New Malden, Surrey. Nov. 5, 1929, No. 33663. [Class 87 (i).] In making bricks, blocks, tiles, and ceramic articles, burnt clay is ground and mixed with unburnt clay while still hot, after which the mixture is moulded and finally burnt without preliminary drying. The hot burnt clay from the rotary kiln 5 falls on to a screw convever 13 whence it is taken by a conveyer 15 working in a heat-insulating housing 18 to a grinding mill 16 which delivers it still hot to a pug mill 20 where it is mixed with wet plastic clay which it warms and dehydrates. The amount of slurry admitted to the pug mill is such that the final product has the correct plasticity for the extrusion or moulding process, which is carried out in the machine 23. The moulded articles are conveyed immediately on a truck to the final kiln. Articles distorted in moulding are placed on a conveyer which takes them back to the conveyer 13.

Abstract: 736,280. Television pick-up tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 4, 1953 [Dec. 9, 1952], No. 33783/53. Class 39 (1). In a television camera tube comprising a photo-electric cathode 5 on which the optical image is projected, a target 8 on which the electron image is projected and which is scanned on the same side by an electron beam from an electrode system 12-17 arranged at one side of the target, and electron-optical means such as a magnetic system 9 for controlling the magnification, a screen 18 is arranged in proximity to, and along the edge of the target remote from the electrode system 12-17 for preventing photo-electrons from reaching a narrow strip along the edge of the target, irrespective of the magnification; the screen 18 is spaced from the target 8 at the minimum distance such that the scanning beam is enabled to sweep the entire surface of the target without being intercepted by the screen. The scanning beam thus regularly strikes a - part of the target which is not struck by photoelectrons and the regular addition of an impulse of constant magnitude to the image signal acts to keep constant the mean brilliance level of the picture produced in the receiver tube. The magnetic system 9 consists of a combination of windings which enables the magnification to be controlled. Reference is also made to a known similar type of camera tube but with constant magnification, having an opaque strip arranged along one edge of the photo-electric cathode and forming a shadow on the target electrode.

Abstract: 1,174,095. Supply systems for arc furnaces. ENGLISH STEEL CORP. Ltd. 3 Nov., 1967 [4 Aug., 1966], No. 34911/66. Heading H2H. [Also in Division C7] In order to induce a refining action in an electric arc furnace 1 fed from an A.C. source 7, means are provided to superimpose a direct current upon the alternating current flowing between the electrodes 2 and the hearth 8, the direct current being obtained from either an external source 15 or from the self-rectifying action of the furnace. The electrodes 2 are normally supplied from the A.C. source 7 by way of a transformer 5. When the self-rectifying action of the furnace is to be utilized, a switch 13 is closed, whereupon a direct current will flow between the electrodes 2 and the hearth 8 by way of a circuit including an inductor 9. When the external source 15 is to be used a switch 21 is closed and the switch 13 left open whereupon the generator 15 causes a direct current to flow between the electrodes and hearth by way of the inductor 9. The windings on each leg of the inductor are divided into two counter-wound portions and are connected in pairs on different legs, thus preventing saturation of the inductor. The polarity of the voltage supplied by the generator 15 may be reversed by means of a switch 18 and the magnitude thereof varied by a potentiometer 20. If desired, the furnace may incorporate an auxiliary electrode and the direct current caused to flow between this electrode and the hearth. In a further arrangement the transformer 5 is provided with a star-connected secondary winding and a source of direct current connected between the star point thereof and the hearth.
