Title: Vehicle windscreen cleaning systems
Inventor: HADEKEL RUBEN
IPC: B60S1/48
Filed: 1967-08-31
Abstract: 1,236,398. Windscreen cleaning systems. TRICO-FOLBERTH Ltd. 30 Aug., 1968 [31 Aug., 1967 (2)], Nos. 48180/70 and 48181/70. Divided out of 1,236,397. Heading A4F. A windscreen cleaning system comprises a pump 21 for passing cleaning liquid from a reservoir 204 to a nozzle or nozzles, an electric motor 20 for driving the pump, and a rotary electric switch driven by the motor 20 and arranged to switch the motor off after it has been running for a predetermined period. The rotary switch comprises a disc 24 of insulating material carrying conducting arcuate and circular conducting elements 26, 27, respectively. In the rest position a brush contact 29 connected to the washer motor 20 lies in a gap in the element 26, and the motor 20 is stanted by actuating a push button switch 33. The rotary switch then turns so that the washer motor circuit is completed to earth via brush 29, element 26, and a further brush contact 28, and the push button switch 33 may be released so that the motor 20 continues to be energized for one complete revolution after which the brush contact 29 again registers with the gap in the element 26. During rotation of the switch delivery of liquid to the nozzle or nozzles is rendered intermittent by the repeated opening and closing of a valve 22 by a multi-lobe cam 23 formed on the disc 24. In the rest position of the switch terminals B and R of a windscreen wiper motor 16 are connected together via brush contacts 30, 31 and a switch 17, if the latter is set in the "parking position", and the motor 16 is stopped with the wipers parked. On movement of the disc 24 the terminal R is connected to earth via contacts 30 and 32 and the motor 16 will run for a complete revolution of the disc 24. In an alternative embodiment the wiper motor is switched on and off to produce a succession of cycles of wiper operation separated by periods of rest; and in a further embodiment a differently arranged rotary switch controls the energization of the washer and wiper motors from a single battery.

Abstract: 1,143,274. Resistance spot welding. INTERNATIONAL STANDARD ELECTRIC CORP. 25 Oct., 1967 [28 Oct., 1966], No. 48474/67. Heading B3R. [Also in Division H2] A method of welding and hence electrically connecting bare conductor 14 to a conductor 11 covered by insulation 12 comprises the steps of placing the bare conductor in contact with the insulation and in parallel overlapping relationship with the conductor 11, placing two closely - spaced parallel electrodes 16 of a resistance welder in contact with the surface of conductor 14 opposite to that in contact with the insulation, applying an electrical pulse to the electrodes to cause current flow through that portion of the bare conductor between the electrodes, whereby the insulation between a portion of the bare conductor and the underlying portion of the insulated conductor melts, urging the two conductors into contact, and welding the conductors together by passage of a second pulse. The insulated conductor may be a thin ribbon or flat cable, and may have a conductivity higher than that of the bare conductor. The conductor 11 may be an alloy containing a high percentage of copper. The pulses may be of equal magnitude and duration, e.g. 1 volt constant for 40 milliseconds. The tips of the electrodes are formed with V-shaped recesses.

Title: Device for supplying fluid to a tandem line fluid system
IPC: F16N7/38
Filed: 1975-12-09
Abstract: 1504309 Lubricating DROPSA SpA 9 Dec 1975 [15 May 1975] 50516/75 Heading F2A A device for supplying fluid, e.g. lubricating grease, to a tandem line fluid system comprises pumping means 5 driven by an electric motor and a slide valve 12 for alternately supplying the pressure fluid to either of the two lines, the electric motor being reversible such that in one direction it drives the pump through a first freewheel 7 and in the other direction it actuates the slide valve through a second freewheel 24 which transmits torque in the opposite direction. In operation, fluid is supplied from a reservoir 1 to four reciprocating pumps 34-37. The pumps are driven by cams 30, 31 on a shaft 28 which is rotated through freewheel 7 by a worm 8 on the motor. The pumps are arranged in pairs and the outlets 43, 45 from each pair terminate in a common inlet to the valve 12. The valve supplies the fluid to one line 16 until fluid pressure in the line activates a sensor 91. The sensor reverses the motor, thereby stopping the shaft 28 and starting a shaft 25. The rotation of the shaft 25 actuates the valve 12 such that the first line is closed and the second line opened. A cam 82 on the shaft 25 closing one of two contacts 13, 14 reverses the motor again and restarts the pumps. An arm 67 and doctor blade 54 are rotated in the reservoir. Also as the shaft 28 rotates, a paddle 63 is displaced upwardly by the engagement of a pin 65 on an inclined plane 66; in the absence of grease, a spring 70 moves the paddle downwardly and closes a contact 61 to light a warning light.

Abstract: 1443030 Methane drainage in mines COAL INDUSTRY (PATENTS) Ltd 24 Oct 1974 [2 Nov 1973] 50986/73 Heading E1X A method of sealing a tube 6 in a borehole comprises the steps of inserting a frangible, sealed, cylindrical cartridge 1 containing a sealing material 2 into the borehole, forcing the cartridge up the bore to the innermost end thereof, applying pressure to the cartridge to cause it to burst and passing the tube 6 up to the end of the bore so that the sealing material fills the gap between the tube 6 and the wall of the bore 12. Preferably the sealing material is a two part resin contained within the cartridge. The resin may be in a thixotropic form with a catalyst suitably dispersed therein to facilitate setting of the material when it is mixed up. The cartridge cylinder may be sealed at one end by a plug 4 and at the other by a frangible end part 3 set a short distance within the cylinder. The tube 6 is used for breaking open the cartridge and may be used to mix the sealing material freed from the cartridge when it is broken. Mixing blades 9 may be formed on the tube 6. A flexible collar 8 is fitted on the tube to retain the sealing material in the borehole until it sets.

Filed: 1972-11-07
Abstract: 1406325 Combine harvesters S STOKLAND 7 Nov 1972 [8 Nov 1971] 51217/72 Heading A1F A combine harvester is characterised by having two straw walkers mounted one below the other with means for dividing the threshed crop between them. The crop from conveyor 1 is fed past two threshing cylinders 3, 3a in turn and then into the space between the drum 7 and the baffle 8. The lower part of the baffle has a number of fingers (Fig 2) which allow part of the crop to fall onto the lower straw walker 10 while the remainder passes onto the upper straw walker 11. The division of material between the walkers is determined mainly by the width of the opening 15 between the fingers but can be adjusted to suit wet straw by bending some of the fingers 17'. To assist the process by cutting the straw are two knives 18 attached to the baffle 8 which project into circumferential slits 19 in the drum 7. Alternatively there may be one knife on the centre line. Straw is discharged at the rear. Grain and chaff from the first threshing stage passes through the concave 4 onto the shaking table 12 where it joins that dropping through the straw walker 10. The total is carried by an auger 12' and an elevator 14 to the cleaning apparatus (not shown). Also fed to the cleaning apparatus is the grain and chaff firstly from the second threshing cylinder 3a via a concave 4a and an auger 6 and secondly from the upper straw walker 11 via a shaking table 13 on auger 13' and the elevator 14. In another embodiment Fig 3 where only one threshing cylinder 3 is used, the front end A of the upper straw walker 11 has an open structure to allow a portion of the straw to drop through onto the lower straw walker 10. An adjustable baffle plate 16 controls the proportion reaching each straw walker.
