Title: Improvements in cycle stands
IPC: B62H3/08
Filed: 1927-11-03
Abstract: 283,833. Wagner, I., and Neher, C. A., (trading as Wagner & Neher, Maschinenfabrik Eisenbau). Feb. 10, 1927, [Convention date]. Stands.-A cycle stand of the type having one or a series of inclined channeled rests 1 to receive the wheels is provided at the bottom of each rest with a guide or ramp 4, 7, which is adapted to engage the ground and guide the rear wheel into the rest and is pivoted at 5, so that it can be tilted into the position shown, either automatically or by hand or foot, to prevent the cycle from running back or from tilting sideways. The ramp is tilted automatically by the pressure of the rear wheel on a strip metal extension 8, which has a downwardly bent arm 9 passing through a slot in the rest 1. In removing the cycle, the rear wheel is lifted off the ramp, which then rocks by gravity into the normal position, the arm 9 temporarily checking the run of the front wheel down the rest. The rear edge of the ramp is provided with a rounded beading 11 to prevent injury to the tyres. The ramp may be made in two parts 4, 7, the outer part 7 being adapted to fold inwards about the pivot 5 to save space when the stand is not in use.

Title: Liquid level alarm circuit

Abstract: 1514004 Liquid level alarm circuit; proximity warning circuit GENERAL MOTORS CORP 20 July 1976 [4 Aug 1975] 30122/76 Headings G1H and G1N A circuit for monitoring the level of an electrically conductive liquid e.g. the level of coolant in a motor car radiator comprises a probe 14 arranged in a container 12 for the liquid to contact it at a given level, which probe is coupled through capacitor 36 to the A.C. output of an oscillator 22. When the liquid drops out of contact with the probe the A.C. voltage developed at the base of the transistor 40 of the Darlington pair 40, 42 enables both transistors and the alarm lamp 44 is lit. The collectors of the pair are substantially earthed thus both inputs of the NOR gate 46 are low producing a high logic level at its output which tends to latch the Darlington pair on. The high logic level at the output of a second NOR gate 50 inhibits the oscillator circuit via input 34. As a result the alarm lamp 44 is energized continuously once the switching pair 40, 42 has been turned on. The oscillator comprises two NOR gates 24, 26. Since a C-MOS gate package with four dual input NOR gates is readily available and inexpensive the bulk of the monitoring circuit is provided at low cost. Rise of the liquid level to contact the probe earths the base of transistor 40 to turn off the Darlington pair and the lamp and to re-start the oscillator.

[Also in Division D1] An ornamental textile material is produced by firmly securing together two woven textile fabrics 10, 20 heat-shrinkable to different extents by an adhesive 15 supplied in a predetermined pattern to leave areas of the contacting faces of the fabrics free from adhesive and cured to insolubility, and heating the composite product to effect differential shrinkage of the fabrics. In one embodiment, Figs. 1A and 1B, the face fabric 10, e.g. a fabric previously heatshrunk, passes from a supply roll 11 between driven rolls 13, 14, the roll 13 being an intaglio roll having grooves 17 and fed with adhesive 15 using a doctor blade 16. The adhesive 15 may be colourless, of the same colour as the fabric 10 or of a contrasting colour and is preferably a polyurethane-type adhesive. The roll 14 may be of rubber, metal or metal coated with rubber. The backing fabric 20, e.g. a ninon fabric, is guided by a roll 19 to contact the fabric 10 as it passes on to a smooth surface steel or aluminium roll 18 heated internally by steam or electrical elements to evaporate the solvent in the adhesive. The temperature of the drum 18 must be kept below that at which shrinkage of the fabric 20 occurs. The composite product 22 passes around a roll 26 on to a roll 24 and is fed to a wind-up roll 23 on which it is stored at room temperature for 24 hours to allow the polyurethane adhesive to cure. The rolls 19, 24 are preferably provided with a release coating, e.g. polytetrafluoroethylene or a silicon compound. The product 22 is fed on to a smooth surface aluminium or steel roll 25, Fig. 13, heated internally electrically or by steam to cause substantial shrinkage of the fabric 20 to form puckered areas 27. The product is wound on a roll 29 rotated at a slower speed than that of the roll 26. Automatic tension control apparatus may be used. In a second embodiment, Fig. 2 (not shown), a latex adhesive is used and the composite product is heated by passing around a heated roll just after application of the adhesive. The puckered areas 27 may be calendered or ironed either as part of the puckering process or separately. Specified fabrics are those made of silk, cotton, polyesters, e.g. polyethylene terephthalate, polyamides, vinylidene chloride polymers and copolymers with vinyl acetate or vinyl chloride, polyvinyl chloride, polyolefines, e.g. polyethylene and polypropylene, cellulose esters, e.g. cellulose acetate, and regenerated cellulose. The face fabric and the backing fabric may be of the same fibres, the face fabric having been pre-shrunk. A heat-shrinkable fabric may be sandwiched between two substantially non-shrinkable woven fabrics. In another modification, the face fabric may contain yarns which heat-shrink in one direction whereas the backing fabric contains yarns which heat-shrink in a different direction.
