Title: A Pedal Cycle for use on Rail Tracks
IPC: B61D15/10
Filed: 1967-03-06
Abstract: 1,153,085. Railway cycles. BECORIT GRUBENAUSBAU G.m.b.H. 6 March, 1967 [16 March, 1966], No. 10409/67. Heading B7E. A cycle frame 11 and 12 supporting a seat 13 and a chain wheel 15 is itself supported by closely positioned pairs of wheels such as 7 and 8 from an I-sectioned monorail 1. The weight of the rider and cycle causes the frame to pivot and wheel 8 to press down on the lower flange 3 of the rail and the wheel 7 to press upwardly on the flange 2. In Fig. 2 (not shown) pairs of wheels are provided on each side of the web of the rail and one pair may be pivoted away from the rail on a member (6) to release the cycle. The member 6 is normally fixed by engaging a bolt in a hole (21). The rear end of the cycle may be supported by a set of wheels 19 and a spring 17 limited by means 18. Brake shoes 22 may be applied by a lever 23 and the single rail may be replaced by two parallel rails spaced apart either horizontally or vertically. The rail or rails may moreover be floor mounted.

Abstract: 907,232. Stud-and-socket fastenings; rivets. ILLINOIS TOOL WORKS. Jan. 7, 1959, No. 10442/62. Divided out of 907,231. Classes 44 and 89 (1). A fastener unit comprises an article 128 having a rearwardly-projecting stud 130 and a fastener 32e for fixing the stud in an aperture 136 in a panel 138, the fastener being in the form of a member having a head 34e to fit against the panel adjacent to the aperture therein and a shank 36e extending from the head and capable of insertion through the aperture, there being an axial aperture 124 extending through the head and into the shank but terminating short of the end of the shank, for accommodating the stud, the shank having a transversely yieldable portion 126 including a shoulder 118 which faces obliquely towards the head when the fastener is unstressed and which is capable of engaging behind the panel adjacent to the aperture therein after insertion of the shank and which has an inner surface capable of engaging the stud, the arrangement being such that insertion of the stud into the shank prevents subsequent inward yielding of the transversely yieldable shank portion so as to hold the stud and fastener mounted on the panel and the stud and fastener seal the aperture in the panel. As shown, the engagement of the shoulder 118 is at the edge of the aperture 136. In another arrangement, Figs. 3 and 4 (not shown), the stud is formed with a plurality of stepped portions which engage a similarly-shaped aperture in the shank of the fastener.

Abstract: 547,942. Olefines. STANDARD OIL DEVELOPMENT CO. June 19, 1940, No. 10574. Convention date, Aug. 19, 1953. [Class 2 (iii)] Olefines are separated from gas mixtures containing them by'selective absorption in a saturated solution of a cuprous salt in an ether, nitrile or phosphate. Olefines mentioned are ethylene, propylene, butylene and 1:3- butadiene ; cuprous chloride and sulphocyanate are given as examples of cuprous salts, and dioxane, aceto- and benzo-nitriles and tricresyl phosphate as examples of solvents. The absorption, which is normally carried out at a pressure above atmospheric, is effected batchwise or continuously, and preferably in a countercurrent tower.

Abstract: 302,640. Browne, V. B. Dec. 19, 1927, [Convention date]. Ribbon and tape; electric fittings.-Iron-chromium-aluminium alloys, especially such alloys containing 5-30 per cent chromium and. 3-10 per cent aluminium, the remainder being iron with as low a carbon content as possible are worked from the ingot by forging or rolling in a series of stages, each of which is effected at a temperature lower than that of the preceding stage. The final reduction is effected at a temperature below 1400‹ F., and is preferably carried out while the work is cold. The finished product is annealed at a temperature below 1450‹ F. The process is stated to yield strips, which are ductile and which resist oxidation at high temperatures. The application of such strips to the manufacture of soft, ductile resistance grids is indicated. The alloys may be manufactured in an electric arc furnace, the aluminium being added just before teeming. Numerical data of a particular example of the process of working are given in the Specification. Specification 294,246, [Class 83 (iv), Metals, Working], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application of the invention to the production of wire and light-gauge sheets.

Winding apparatus includes an indexable turret 6 provided along its-- periphery with freely rotatable spindles 3 driven by the contact rollers 4, 5 which are in turn driven by constant speed drive belts 29, 33. The rollers 4, 5 are mounted on pivotally supported, power actuated supports. When a roll is fully wound the turret 6 is indexed for a core change. Wound roll is indexed to a position 71, Fig. 4, at which web tension is maintained by a belt 72 driven at a peripheral speed corresponding to that of contact rollers 4, 5 and the new core at position 74 is accelerated by a pivotally mounted drive roller 73 to the speed of winding. A knife blade 79, Fig. 5, mounted on a pivotal support 78 is actuated to sever the web 1. Trailing end 83 is attached to the web roll by a synchronously driven pivotally mounted roller (93, Fig. 6) acting on a roller 60, Fig. 7b. The roller may be a printing or labelling device. The leading end is tucked in about the new core by a pair of pull-in rollers 85, 86 co-operating with the contact roller 4 and the leading end emerging from the nip formed by the core 2 and the roller 86 may be blown into contact with the core and web 1, by air blast issuing from nozzles 87 associated with the pivotal support of roller 86. Completed web roll is removed from the winding spindle by a stripper finger 96, Fig. 7b, which is mounted for a sliding movement by a drive member 105, on a pivotal support 98. New web core is mounted in like manner by a slidable finger (119, Fig. 9a) and the core is clamped to the spindle 3 by a locking member 107, which is released by a pusher 102 acting on a slide bolt 106. Tension of web 1, which is wound at constant speed on the spindle 3, is controlled by a dancer roller 12, Fig. 5, acting indirectly on a shaft 38, Fig. 2 of a drive unit 20 which controls the drive of the web roll 7 driven by belts 13. During controlling of tension the speed of the drive unit 19 driving the contact rollers 4, 5, and rollers (93, Fig. 6) as well as roller 73, Fig. 4, at constant speed is locked. The speed of drive unit 19 is preselected at the beginning of the winding operation by a hand wheel (58, Fig. 3b).
