Title: Improvements in and relating to windshield cleaners
IPC: B60S1/18
Filed: 1938-01-28
Abstract: 491,700. Windscreen - cleaners. TRIGGS, W. W. (Trico Products Corporation) Jan. 28, 1938, No. 2724. [Class 138 (i)] In a wiper-actuating mechanism of the kind in which the wiper-actuating shaft 6 is rotated by a worm 12 fast on a transmission shaft 5 which is slidable in the casing 8 and is connected, through a dutch at its other end, to a moving part of the engine, the casing 8 in which the shaft 6 is mounted is pivoted on a stud 9 projecting from a frame member 10. Freely pivoted on a rock-shaft 28 on the casing is a lever 27 adapted to be moved by a hand control 29 and carrying a stud 25 movable in a cam slot 26 in the member 10 and also a lug 19 adapted to be moved into the path of rotation of anextension 18 of the wiper-actuating crank arm 17. Fixed to the shaft 28 are an arm 30 with a slot 31 engaged by the stud 25 and an arm 32 engaging a slot 33 in a slide 34 mounted to move axially, but not rotatably, with the shaft 5. Fig. 2 shows the wiper-actuating position of the parts. To stop the wiper, the lever 27 is swung clockwise by the control 29 so that the lug 19 arrests the crank arm 17 with the wiper at one end of its stroke. At the same time, the stud 25 moving in the slot 26 rocks the casing 8 to the position shown in Fig. 1, thus moving the shaft 6, and the wiper, to parked position. When the shaft 6 is arrested by the lug 19, the worm 12 rides on the worm wheel 13, moving the shaft 5 axially so as to declutch it from its prime mover. To start the wiper, the lever 27 is returned to the position of Fig. 2. This releases the shaft 6, rocks the casing 8 to operative position, and causes the arm 32 to move the slide 34 to the left to clutch the shaft 5 to the prime mover. The slide 34 is held in its extreme positions by a detent 40 engaging countersunk sockets 41, 42 in the slide.

Abstract: 1458103 Treating mercury containing wastes CHEM-TROL POLLUTION SERVICES Inc 21 Jan 1974 [19 Jan 1973] 02734/74 Heading C1A Wastes containing mercuric compounds, e.g. mercury muds from electrolytic processes, are treated with at least an equal amount by weight of spent pickle liquor containing sulphuric acid to convert mercury compounds into basic mercuric sulphate and then with a lime slurry to neutralize the mixture and obtain a solid mass containing insoluble mercuric carbonate and a liquid portion containing less than 10 p.p.b. soluble mercury. When the waste contains metallic mercury it is first treated with H 2 SO 4  e.g. a form of spent pickle liquor in the presence of an oxidizing agent to form mercuric compounds which are then treated as above. The solid mass may be used as a land fill material without risk of mercury being leached out under alkaline conditions. In one embodiment the mercury mud is first treated with dilute sulphuric acid, e.g. in the form of a pickle liquor, to convert calcium carbonate present to calcium sulphate and cause any finely divided mercury to be oxidized to mercuric chloride or mercuric oxide. The ratio of pickle liquor to treated waste preferably ranges from 1 to 20 : 1 by weight, especially 10 to 1. The lime slurry suitably contains 5 to 28% by weight CaO and is used to neutralize the mixture to pH 7À5.

Abstract: 1456803 Automatic control of arc furnaces ISHIKAWAJIMA-HARIMA JUKOGYO KK 23 Jan 1975 [2 May 1974] 3010/73 Heading G3R An electric arc furnace has an individual prime mover and generator set. The output of the generator is automatically controlled in reponse to a control signal derived from the value of an operating parameter of the furnace. As shown in Fig. 1, a single-electrode arc furnace 3 is supplied from a three-phase A.C. generator 2 driven by a diesel engine or a gas or steam turbine 1, through an impedance matching transformer 5. A detector 7 produces a signal S dependent on the rate of rise of temperature at the furnace wall. This signal controls a voltage regulator 6 connected in the excitation circuit of the generator 2. The signal S may alternatively be derived from measurements of power consumption, power factor, molten bath temperature, electrode current or electrode voltage. In addition to controlling the generator voltage, the frequency of the output may be controlled by varying the speed of the prime mover 1. In the case of a multi-electrode furnace, Fig. 2 (not shown), each electrode may be supplied from a separate prime mover and generator set. Each generator may be controlled in response to a detector located near the corresponding electrode. In another embodiment,.Fig. 3 (not shown), a saturable reactor is connected between the generator 2 and the transformer 5. The control signal from the detector 7 is used to adjust both the generator excitation and the D.C. bias on the saturable reactor.

Abstract: 1,134,443. Converting. LICENTIA PATENTVERWALTUNGS G.m.b.H. 25 Jan., 1966 [26 Jan., 1965], No. 3271/66. Heading H2F. In a converter circuit the moment at which a valve current i 1  falls to zero is detected by a current transformer (4), Fig. 1 (not shown), having its primary in series with the valve, and its secondary connected to an LR circuit. If the current waveform is asymmetrical, and if the transformer saturates at 2 then, with a purely resistive load, the secondary current (shown dashed) would drop to zero, giving a false " valve current zero " indication. To overcome this the inductance (2) is connected in series with the resistance (3) across the transformer secondary winding. If the time constant of the secondary circuit is sufficiently high, then when the transformer saturates the secondary current i 2  is maintained (but decaying exponentially) until the primary current falls at the end of the half-cycle so that correct operation is obtained. A diode may be connected across the secondary winding of the transformer to compensate for error due to magnetizing current (though this small error may be neglected). Zener diodes may shunt the secondary to prevent over-voltages.

Abstract: 740,096. Luminescent. screens. LUMALAMPAN AKTIEBOLAG. Feb. 4, 1954 [Feb. 6, 1953], No. 3360/54. Class 39 (1). [Also in Group XI] In order to apply a coating in powder form to the inside surface of a lamp bulb a combustible medium is burnt within the bulb in oxygen or air which is supplied in a stream to the bulb, and the powder is blown into the bulb in the said stream. The combustible medium may comprise ethyl alcohol or other organic liquid having a high combustion value. Apparatus for applying the coating comprises a vertical cylindrical casing or sleeve 10 supported in bearings in brackets 9, 16 and provided with a pulley 14 for a driving belt 13, the upper end of the sleeve providing a frusto-conical seating 6 for the neck of an inverted bulb 4. Extending upwardly within the sleeve 10 and into the lamp bulb is a tube 5 the lower end of which is connected to aT-junction 17 with one limb connected by a pipe 19 to the outlet 29, Fig. 3, of a powder receptacle 24. A spherical or ellipsoidal container 2 for ethyl alcohol is provided at the upper end of a tube 18 which extends upwardly through the tube 5 and is connected at its lower end to a tube 20 leading to a supply vessel for the liquid. A stream of oxygen is fed into the vessel 24 through a tube 27 which has its outlet below the surface of a supply 30 of the powder that is to be applied, the supply being maintained from a hopper 25 by a screw-conveyer 26. The container 24 is vibrated continuously during the operation. When a light is applied at the outlet 3 at the upper end of the tube 5 and an inverted bulb is placed upon the conical seating 6 the intensity of the flame is increased by the evaporation of the ethyl alcohol from within the container 2, and the application of the powder coating upon the inside wall of the bulb takes place.. A rod 1 inserted into the open top of the container 2 and standing on the bottom thereof is formed with a head 23 substantially of mushroom shape to spread the flame and reduce the risk of overheating the top of the lamp bulb. As described, a mixture of powdered tinting materials are applied to an incandescent lamp bulb by the stream of oxygen, but the method may be used to apply an inner coating of fluorescent powders such as zinc silicate, magnesium tungstate, zinc germanate or aluminium oxide, without the use of a binding medium. Specification 704,189, [Group XI], is referred to.
