Patent GB-2235791-A (GB)
Title: Escalator or travelator control
Inventor: SAKATA KAZUHIRO
IPC: B66B25/00
Filed: 1990-07-10
Abstract: When the control computer 81 of an escalator or other passenger-carrying conveyor malfunctions, a second computer 82 maintains the control signal at its value immediately before the malfunction. A warning may be given to prevent further use of the escalator and to allow the escalator to be stopped manually, eg. when it is empty. Sudden deceleration of a loaded escalator, which may be dangerous, is prevented thereby. Automatic recovery after the malfunction is possible. <IMAGE>

Title: Attaching closure strips to bags
Inventor: JOHNSON JAMES R
IPC: B29C65/74
Filed: 1991-03-07
Abstract: A string zipper (12), with no mounting flanges, is welded to bag material (15) for forming zipper bags. The zipper material (12) is fed from a driven unwind (10) and the bag material (15) receives the zipper as it is being folded by folder (14). Guides (42, 44, 49, 54) place and retain the zipper material wherever desired with respect to the bag material. The bag material, with the zipper material (M), is held by guides (59) between continuously moving belts (62, 64). Stationary heaters (60) are placed against the belts (62, 64), and provide heat through the belts sufficient to weld the bag material to the zipper material. The zipper material is then heated as a preseal (90) before the material is contacted by the side welding blade (20) which completes the seal and separates discrete bags. A presealer using ultrasonic energy directed through a horn 90 is provided to heat the area of the zipper between adjacent bags. The zipper unwind 10 has brake 28 to prevent overrunning, and an adjustable zipper-tensioning arm 30. If the zipper becomes slack, the unwind motor is switched off. <IMAGE>

Patent GB-2263954-A (GB)
Title: A valve for cadence braking
Inventor: VOWLES JOHN CHRISTOPHER
IPC: B60T13/52
Filed: 1993-02-04
Abstract: A valve 10 for cadence braking comprises an inlet 16 connected to an engine vacuum, an outlet 25 connected to a brake servo unit in a vacuum servo-assisted brake system, a housing portion 11, two end caps 12, 13, a spool 14 spring biassed to its illustrated position, and an end plate 15. The end plate 15 incorporates a control tract 28 connecting spaces 19 and 37, and in operation generation of a vacuum in space 19 and in the servo unit will result in a gradual reduction of pressure in space 37 until the spool moves against its spring bias to open spaces 19 and 37 (and its servo unit) to atmosphere via openings 35. When the spaces 19 and 37 are at atmospheric pressure the spool will return to its illustrated position to recommence the cycle. Thus, when the brakes are applied the valve will produce a "pumping" action in the brakes. When there is insufficient vacuum, spring biassed ball 33 blocks tract 28 and prevents the valve operating. The valve may only be operated when the brakes are applied e.g. by utilizing a 'G' switch and/or a solenoid activated by the brake light circuit to open the control tract 28. Also the 'G' switch may only cause the tract to open on harsh braking. <IMAGE>

Patent GB-2265156-A (GB)
Title: Making spherical particles; removing oxide film; solder paste; soldering method
Inventor: OCHIAI MASAYUKI
IPC: C23G5/032
Filed: 1993-03-19
Abstract: Metal particle such as solder is immersed in a heating medium containing a resin or derivative thereof and an organic solvent and heated to a temperature above the molting point of the metal, to remove the oxide film of the metal and make the metal spherical. If a hardened castor oil or high softening point resin or derivative thereof is further added as a thickener to the heating medium, the size increase of the metal particle can be prevented. However by heating at a temperature lower than the melting point of the metal, the oxide film can be removed without making the particles spherical. Using thus obtained solder particles, fluxless soldering can be done. Also, a fluxless soldering method is provided in which after applying solder onto a first part to be soldered the oxide film is removed therefrom. The solder may be selected for InSn, SnPb, In Pb and In. Suitable solvent used are glycerol, tetraethyleneglycol, diethylene glycol mono-n-butylether, ethylene glycol monoethyl ether acetate, diethylene glycol monoethyl ether, or ethylene glycol monohexyl ether.
Patent GB-2266418-A (GB)
Title: Control apparatus for an electic generator of a bicycle
Inventor: NAGANO MASASHI
IPC: B62J6/06
Filed: 1993-04-21
Abstract: The generator 1 is switchable between a generating state and a non-generating state, in which no power or only a small amount of power is generated, by a controller 2 responsive to detection of the need to supply power to an operating device 7. An ambient light sensor 3 may be used to detect the need to power a headlight 7. The sensor 3 may be a solar battery which is also used to charge a battery 4b supplying power to controller 2 and to a solenoid 23. A lock 21 is released on energisation of solenoid 23 so that the generator magnet M then remains stationary and the generator is in its non- generating state. An auxiliary generator (14), (Figs 4, 5), may be used instead of battery 4b to energise controller 2 and solenoid 23. This auxiliary generator may also be dispensed with if the generator 1 produces a small amount of power in its non-generating state. An alternative arrangement renders the generator 1 operative to power a radio (16), (Fig 6), when controller 2 senses that a radio switch (17) is on. Other ways of rendering generator 1 non-operative include causing the stator coil C to rotate with the magnet M (Fig 7), varying the coil C/magnet M spacing (Fig 8), and inserting a magnetism blocking element (18), (Fig 9), between the coil C and magnet M. <IMAGE>
