Title: Method and apparatus for transporting sheets
IPC: B65H3/08
Filed: 1980-12-17
Abstract: In a paper feeder wherein sheets are lifted by means of a suction head the number of movements of sheets from one position to another cannot be increased by increasing the speed as the speed at which the sheet is moved must not exceed a certain limit in order to prevent the paper from crumpling or flying. By using a method and an apparatus wherein it is the same suction head which both lifts and transports sheets the required distance from pile to conveyor belt and with an additional suction head (15) for moving sheets (1), the moving capacity can be doubled without increasing the speed. The apparatus is provided with suction heads (15) on arms (12) which are moved from a central shaft (7) by cam discs (8, 9) and rods (10, 11) in such a way that the path of movement of the arms does not cross each other, the return path running over the feeding path. <IMAGE>

Title: Signal processing circuit
IPC: H04N9/793
Filed: 1981-02-27
Abstract: A video signal recorder/reproducer comprises a multi-functioning circuit, selected elements of which are used commonly in both recording and reproducing modes. Color signals are obtained from the output terminal of a color signal amplifier (41) in both modes. In the recording mode, color signals appearing at the output terminal of the color signal amplifier are by-passed by a low-pass filter (42), and only ACC detector voltages which are used as color killer signals are supplied to a mixer circuit (16) which mixes brightness (Y) and color (C) signals for recording. Circuit (16), when necessary, prevents color signals from being supplied to a recording head (H1) in response to color killer signals. In the reproducing mode, color signals appearing at the output terminal of the color signal amplifier are supplied to a mixer (60) which provides composite color signals from brightness and color signals. Comb filter (35) serves in the recording mode to separate brightness and colour signals and in the reproducing mode to remove crosstalk components. <IMAGE>

Title: Method and apparatus for applying marking lines to a road surface
IPC: E01F9/08
Filed: 1978-10-09
Abstract: A durable and immediately reflective marking line is formed on a roadway by the steps of (1) projecting a continuous stream of a marking material in the wet state onto a roadway to form a marking line on said roadway; (2) projecting a continuous stream of glass beads from an outlet into said stream of marking material before said stream reaches the roadway; and (3) simultaneously with (2) dropping a second stream of glass beads from a second outlet onto the top of the marking line on said roadway before said line dried to impart immediate reflectivity to said marking line. Apparatus for this purpose may be in the form of a spray unit (20) for projecting the stream and a glass bead dispensing means including means for projecting glass- beads from a first outlet (46) into the stream of marking material as it is supplied to said roadway and before it contacts said roadway; and means for, simultaneously with said projecting of glass beads into said stream of marking material, dropping a second stream of glass beads upon the marking line from a second outlet (47) immediately after said line has been applied to said road surface. <IMAGE>

Title: Lubrication apparatus and method
IPC: F16N7/22
Filed: 1981-04-08
Abstract: Bearings 5 on a high speed shaft 10 are automatically lubricated by lubrication fluid F from a reservoir 15 beneath the shaft. Automatic lubrication is achieved by gravitionally suspending a large diameter ring 20 from the shaft so that the ring carries fluid to the nip between the inner surface of the ring and the shaft, and by providing fluid accelerating discs 25 adjacent the nip for centrifugally accelerating a portion of the fluid and for tangentially discharging it into a secondary reservoir 31 by which it may be transferred by gravitational feeds 34 to the bearings 5. <IMAGE>
Patent GB-2076237-A (GB)
Title: Electrical resistance monitoring device
IPC: G01R27/18
Filed: 1981-04-21
Abstract: An electrical resistance monitoring device is arranged to be capable of detecting changes in the electrical resistance of a load irrespective of changes in supply line voltages to the resistance. The device has load current and load voltage sensors and these sensors each generate an output signal (at 5, 6 and 7, 9) corresponding to the load current and load voltage. Balancing means RV1 balance the load voltage and load current signals so the device is not actuated when the resistance value is normal. An out of balance signal due to a change in the electrical resistance is detected (IC1) and an alarm RLY1 is operated. The device may be arranged such that when the normal supply is disconnected from the load an alternative, low- voltage supply is substituted, so that the resistance can be monitored even when the load is deenergised. The invention finds particular application in detecting the failure of heating tapes arranged in parallel. <IMAGE>
Patent GB-2077158-A (GB)
Title: Wet grit blasting
IPC: B24C7/00
Filed: 1981-06-08
Abstract: Air from a compressor (T) is used both for entraining grit in a line from a regulator valve (E) to a nozzle (N) and for pressurizing in a tank (A) so that a stream of compressed air, pressurized liquid and grit is ejected from the blast nozzle to effect wet grit blasting of structural fabrications. The pressurized liquid passes through a valve (P) to an injector (K) or downstream or even in the nozzle, to join compressed air from the valve (E). The grit is fed by a screw metering unit (W) from a tank (L) pressurized by the air. Pilot valves (H) are controlled by a deadman's valve (X). This controls the outlet (P) and grit tank pressurization. Helmets (R) are supplied by the air via individual valves (Y). A dry grit blasting system is convertible to a wet grit blasting system above. <IMAGE>
Patent GB-2101104-A (GB)
Title: Closure for containers
Inventor: STOW BRIAN DAVID
IPC: B65D55/02
Filed: 1981-07-02
Abstract: A plug-type closure for the mouth of a composite container 2 having an inwardly curled edge is flexible, being for example formed by thermo-forming in relatively thin- plastics. It has an external bead 22 which interferes heavily with the inward curl so that the closure fits very firmly to resist accidental removal. Two recesses 10 extend into the closure from its topside. When fingers are inserted into the recesses and squeezed together, the closure deforms, this deformation being assisted by indents 28 which locally reduce the stiffness of its peripheral portion, in such a way that there is a tendency for the peripheral closure portion to be disengaged from the curled container rim in a localised area. By imposing this deformation and simultaneously applying a closure-removing force by means of the fingers, progressive removal of the closure from the container can be achieved without difficulty. <IMAGE>

Title: Optical data link
Inventor: BREWSTER ARTHUR EDWARD
IPC: H04B10/118
Filed: 1982-09-24
Abstract: Each optical head of a free space optical data link includes a lens (21,22) at whose focus an end of an optical fibre (23,24) is arranged. The opto-electronic transducers (25, 28), for converting electronic signals to be transmitted to optical form and converting received optical signals to electronic form, are arranged at the other ends of the optical fibres so that the transducer may be arranged remotely from the optical heads, for example in the buildings on the roofs of which the optical heads are arranged. Adjustment means are provided for use in aligning the optical heads in attitude and azimuth, focusing, and adjusting the optical fibre to lie on the axis of the lens. A method is described of achieving maximum transmitted signal amplitude by modulation of an audio signal at the receiver in accordance with the received intensity and feeding back the modulated signal via 32 to the transmitter end to allow correct alignment of the transmitter. <IMAGE>
