Title: Washing device
IPC: A47L17/00
Filed: 1961-12-14
Abstract: 952,395. Self-feeding brushes. G. HANNINGTON. Dec. 14, 1962 [Dec. 14, 1961], No. 44865/61. Heading A4K. In a brush 1 through which water is fed from a mains supply, a pressbutton 25 controls a flow of detergent through pipe 15 from a tank under mains water pressure. As shown, water from the mains supply tap 33 is fed directly into detergent tank 44 through pipe 43 and stand pipe 44. The water also flows in the opposite direction in pipe 43 to the brush. In another position of a rotary plug valve, water from tap 33 runs downwardly to waste thus by-passing pipe 43. On pressing button 25, pipe 15 is allowed to expand away from fixed cross-pin 23 and detergent enters pipe 52 which has a bleed hole 53. The detergent mingles with the water in pipe 5 and the mixture emerges from hole 3 in rubber stock 2. In another form of tank (Fig. 4, not shown), the water enters between a flexible detergent containing lining, which is collapsed as the tank is filled with water, and the tank wall. Alternatively, an airtight tank may have a partition so that, on filling one compartment with water, air is transferred into the other to displace the detergent therefrom. The tap fitting may have separate inlets for hot and cold water. According to the Provisional Specification, the detergent may be in a squeezable container having a valve so that a pliable tube 15 can be filled with detergent by squeezing the container. The mains water pressure then feeds the detergent from tube 15 to the brush. A slide valve may replace the rotary plug valve for running the water to waste. Reference is made to the use of a suction feed for the detergent.

The apparatus of the parent Specification 1,091,596 (Application No. 44101/64) for measuring the displacement of a scale is modified in that as the electron beam scans the screen of the cathode ray tube (Fig. 1, not shown) it impinges on each of the grid elements (1 . . . 10) in turn to give an output on four leads (A, B, C, D) in turn. The signal on each of these leads is passed via an associated flip flop, e.g. F B  (Fig. 2) to two AND gates R B , V B  one of which is enabled depending on whether the previous signal was received on lead A or lead C. The enabled gate passes a signal to either OR gate R z  or OR gate V z  to indicate a backward or forward count in an associated counter to indicate not only the amount by which the scale has moved but also the direction in which it is moved.

An electric drive for a drilling rig winch includes an asynchronous motor having at least two arcuate stators 7 and a rotor 6 serving also as a flywheel of an electromagnetic clutch having an armature 4 capable of rotating in both rotary directions and adapted to be mechanically connected to the winch drum 1. The arcuate stators are supplied with 3-phase current from diesel-driven generators 13, as shown, or from a mains supply. The armature 4 is connected to the drum 1 through gearing 3 and a pneumatic tyre clutch 2. During lowering of tools in a drilled hole the clutch field 5 is initially disconnected from its exciter 14 and the armature 4 rotates freely with the drum 1. At a predetermined speed of the drum the field 5 is energized and applies a reverse torque on the armature 4, so slowing down the drum 1. Control of the exciting current in field 5 permits stopping of the drum or even reverse rotation to raise the tools. The exciter 14 is driven through a belt 15 by the shaft of the flywheel. Tachogenerators 19 on the shafts of the armature 4 and flywheel 6 control the switching in and out of circuit of resistors 16 in the circuit of the armature 4. During sinking of a well the clutch 2 is disengaged and the output of the exciter 14 is supplied to a D.C. motor 20 driving the drum 1 through a belt 22 and a pneumatic tyre clutch 23.
