Title: An electromagnetic apparatus for collecting electric currents from space
IPC: A61N1/16
Filed: 1925-11-02
Abstract: 244,723. Christofleau, J. E. Dec. 19, 1924, [Convention date]. Atmospheric and terrestrial electricity, utilizing. - A device for collecting electricity from space and utilizing earth currents for assisting the growth of vegetation consists of two magnetized plates with poles of opposite sign facing each other and enclosing the base of an aerial collector and the base of a tail part of the device, which is set so as to point towards the South. The collected currents flow to earth through a wire connected to a bolt on the North side of the apparatus. The form shown consists of a box A adapted to be mounted on the top of a pole and supporting aerial collectors L and a tail B. The aerials collect electricity from the air and clouds. The box has external cooling ribs C and internal heat-retaining bosses D of different metals such that when the sun shines on any ribbed side of the box the difference in temperature between the ribs and bosses generates current. The top of the box is formed by a zinc tray 0 in which a copper plate P is riveted. Rain water entering between the plate and tray generates currents which flow to earth through a wire R attached to a terminal bolt K. A tube G composed of dissimilar metals soldered together at 1 generates thermo-electricity when the sun shines on one side of it, this being carried to the aerial support F by means of a bolt J. The two plates H of magnetized steel are connected to the box A by rivets Q, with dissimilar poles opposite each other. The Specification, as open to inspection under Sect. 91 (3) (a) states also that the device may be used for collecting " magnetic currents " and electricity from fog; also that vibration of the aerial wires L by the wind causes the production of electricity. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in windscreen cleaning systems
IPC: B60S1/50
Filed: 1954-09-23
Abstract: 801,434. Windscreen cleaners. TRICO PRODUCTS CORPORATION. Sept. 23, 1954 [Sept. 30, 1953], No. 27554/54. Class 138(1). A system for cleaning windscreens comprises a wiper driven by a motor 7 having a control 11, a washer unit including a pump 15 delivering liquid to a nozzle 12, and a co-ordinator unit which in response to pressure of liquid delivered to the nozzle 12, starts the motor 7 if this is initially at rest, or accelerates the motor if it is initially running at a low speed. On closing a switch 22 an electromagnetic valve 20, as described in Specification 757,231, connects pump motor 18 to an evacuating pump 9 over conduit 19 and draws liquid from reservoir 24 into the pump chamber. When fully charged the pump 15 trips the valve 20 and discharges liquid over a conduit 13 through the nozzle 12. A valve 39 is connected in the path of conduit 13 such that liquid in the conduit deflects a diaphragm 45 to operate a slide valve 42 to connect ports 40 and 41 and thereby connect the evacuating pump 9 to a pneumatic motor 31, comprising the co-ordinator unit, over a conduit 33. Evacuation of the motor 31 draws a piston against a spring 36 and at the end of its motion the piston engages an abutment on a spindle along which the piston slides and by this means operates the control valve 11 of the wiper motor 7 over a Bowden cable 32. The operation of the pneumatic motor 31 in controlling the valve 11, and conjoint manual control of the valve by means of a Bowden cable 38, is described in Specification 801,433. When liquid from the pump 15 is fully discharged valve 39 disconnects the motor 31 from the evacuating pump 9 and the piston of the motor retreats under the action of spring 36 at a rate determined by a bleed valve 37. At the end of its motion the piston re-engages its spindle and operates Bowden cable 32 to reset the motor control valve 11 to its initial condition. Instead of using a pneumatic motor the co-ordinator unit may employ a solenoid to operate the control valve 11, the solenoid being connected up by a switch in the valve 39 and having an armature which returns under the action of a spring in association with a dashpot. Specification 736;380 also is referred to.

Filed: 1970-06-08
Abstract: 1284959 Fluid-pressure servomotor systems NORMALAIR-GARRETT (HOLDINGS) Ltd 3 June 1971 [8 June 1970] 27572/70 Heading G3P A fluidic means for controlling cabin temperature comprises a pressurised fluid supply 1, Fig. 1, a fluidic amplifier 10 controlling a valve 2, a cabin temperature sensor 6 operative upon the fluidic amplifier, selectable temperature control means 9 operative upon the amplifier in opposed relationship to the cabin temperature sensor, manual override means 7 operative to divert the output from the amplifier, and modulation means 8 to regulate the effect of the override means. The valve 2 is operated by a power relay 5 from an amplifier 10 and regulates the flow of hot air through a duct 3 towards a junction with a cold air duct 18 which communicates with a distribution duct 11 through an ice screen 16, a water separator 15 and a non-return valve 14. Variations in cabin temperature alter the position of a bi-metallic sensor 6 in a miniature wall attachment type ejector pump 22, Fig. 2, through which cabin air passes via inlets 24 and outlet 25. A control jet 26 adjusted by the sensor opposes a jet 27 manually adjusted by a needle valve. 9 to provide a variable output from an amplifier A2 to amplifiers A3 and A4 connected to the power relay 5 through a noise attenuator 39. The amplifier A2 also receives a signal corresponding to rate of change of temperature from amplifier A1, A5 and a probe 12 having an outer container 34 changing temperature faster than a lagged member 33 to operate a vent valve 30. Operation of the manual control 7 overrides the signals from the automatic sensors while the valve 8 provides a signal opposing the override and allows manual control of the valve 2. The relay 5 is vented via a probe 17 which ices up before any serious icing of the system occurs so as to build up a back pressure to open the valve 2. Excess temperature causes a control 13 operated by a bi-metallic sensor 31 to open a valve 32 in the supply line to the relay 5 which closes the valve 2.

Abstract: 304,261. Cameo (Machinery), Ltd., and Williams, J. C. Oct. 18, 1927. Delivery apparatus.-In a folding or like machine for operating on paper sheets, the movement of one of the rollers of the machine, or a specially provided roller, caused by a sheet traversing it, is utilized to drive a part or parts of the machine such as a delivery band for further operating on the sheet. As shown in Fig. 1, the folded sheets leaving a buckling folder 4 pass along guides 23 and between feeding and slitting rolls 5 to two rollers 8, 9, the roller 8 being positively driven and the roller 9 being adjusted by means of nuts 12 and spring washers 14 so as to be rotated by the passage of a folded sheet. The roller 9 is of brass and is geared by reduction gearing 17 - - 20 to a pinion 21 driving a delivery band 22, so that the band is moving as the front edge of the sheet moves on it, and the delivery of rough-surfaced paper is facilitated. Also, the small movement of the band prevents interleaving of successive sheets. The roller 9 is mounted on ball-bearings and may have a resilient mounting. The rolls 5, 8, 9 and gears 17 - - 20 may be carried in a detachable casing 15. In another embodiment, Fig. 3, the downward movement of one of the folding rolls 3, caused by the passage of the sheet, tilts a twoarmed lever 31, and a pivoted pawl 33 carried thereby engages a ratchet disc 35 on the shaft of one of the delivery-belt rollers 21 so as to operate the belt. The rollers 21 run on ballbearings. A stop 34 on one arm of the lever 31 limits the movement of the pawl, which, however, may be spring-controlled. A member 32 adjustable on the lever 31 by means of a screw 36, and having its upward movement limited by a stop 32<1>, is in contact with the roller 3 or with a collar thereon, and serves as the operating member for the lever 31. In a modification, the rotary movement of the roller 3, caused by a sheet traversing it, effects the movement of the delivery belt through an intermediate adjustablymounted disc, frictionally engaging the roller 3, and having thereon a gearwheel engaging a gearwheel on the shaft of one of the belt pulleys. Counting-apparatus. - A counter may be provided for use in conjunction with the deliveryband 22 and is operated by a lever moved similarly to the lever 31..

Title: Vehicles with guidance means
IPC: G05D1/02
Filed: 1975-07-03
Abstract: 1500970 Line followers LEAR SIEGLER Inc 3 July 1975 [16 July 1974] 28101/75 Heading G1A [Also in Division G3]  In a vehicle guidance system in which a vehicle is made to follow a line which it illuminates, the line includes a material which emits a first wavelength when illuminated by a second wavelength. The line may be fluorescent, in which case the illumination is ultraviolet and the emission from the line is visible; the source of illumination is filtered to provide only UV and the photo-detectors of the system are filtered or otherwise selected to respond only to appropriate visible wavelengths. The source may be modulated to ease detection of the fluorescence by synchronous demodulation, and various AGC and other circuits are proposed to counter background illumination and to prevent operation in the absence of a line. In Fig. 2 a UV source 50 emits radiation on to line 36, all visible emission being blocked by filter 52. Detectors 56, 58, 60 respond only to fluorescence passed by filters 61, and their signals are processed to derive a position error signal, Fig. 3 (not shown). This is used to adjust the steering of the vehicle. A floor scrubber is described to which the guidance system may be applied; a modification allows the system to be used with scrubbers steered by their front or rear wheels.
