Filed: 1975-10-31
Abstract: 1493636 Reciprocating pump for pumping gas ATLAS COPCO AB 31 Oct 1975 [22 Nov 1974] 45368/75 Heading F1N A pump comprises a pumping piston 12 reciprocable and rotatable in a cylinder, the motion of the piston being produced by a mechanism comprising a single row spherical ball bearing having an outer race 21 eccentrically mounted for rotation with a motor drive-shaft 2 and an inner race 22 on the end of a stub shaft 13 rigidly fixed to the piston 12. The balls 23 of the bearing run in a groove formed in the surface of the inner or the outer race, the other race in each call having a spherical surface. Radial play between the balls and the race surfaces allows the inner race to move axially with respect to the outer race. The inner race 22 and the shaft 13 may be combined to form a single part. A seal 17 retains lubricant in the bearing. Piston 12 has plastics sealing rings (19, 20) and is rendered double-acting by the provision of spring-loaded inlet arid outlet valves (28, 29) at each end of the cylinder, Fig. 2 (not shown).
Patent GB-454981-A (GB)
Abstract: 454,981. Time-checks for games and sports. JELKS, W. M., Abinger, Ingram Avenue, Hampstead, London. June 13, 1935, No. 17060. [Class 132 (ii)] In a time-recording apparatus for billiards or other games or sports, adapted to be inserted in a lighting or power circuit and having a marking device co-operating with a strip or band of paper driven at a uniform speed, the marking device is mounted on a pivoted member which, when the circuit is open, assumes a position wherein the marking device is out of contact with the strip but which on closing the circuit is moved into a position wherein the device contacts with the strip, the contact being maintained until the circuit is again opened whereupon the pivoted member is returned automatically to its inoperative position. As shown, the closure of a switch to illuminate the lamps over a billiard table starts a synchronous motor 17 and energizes an electromagnet 36. The electromagnet rocks a lever 31, 33 and causes a toothed marking wheel 32 to perforate the paper strip 13 as it passes over a roller 24. The motor drives a pair of discs 15 which feed the paper strip at a constant speed from a spool 14. Spring - pressed movable' arms 19 press the strip into contact with teeth on the discs 15 to maintain the drive. The device continues to operate until the switch is again opened when the length of the perforations in the strip indicates against a graduated scale the time during which the circuit has been closed for play. The strip may be driven by clockwork mechanism independently of the switch. A second marking device may be provided and arranged to move into contact with the paper strip when the marker 32 is removed. The marking device may be in the form of an ink marker. The marker may be moved into engagement with the strip through a mechanical connection with the switch or through a relay.

Title: A method and apparatus for stabilizing strip work
IPC: B21C47/34
Filed: 1964-11-09
Abstract: In a plant for heat treating metal strip, Figs. 1 and 2 (not shown) in which the strip (22) passes through treatment chambers (25, 35, 36, 28, 29 etc.) in a predetermined path, the strip (22) is stabilized and supported in at least some of the chambers by fluid bearings (54, 62) extending transversely thereof and arranged in pairs spaced longitudinally of the strip.  The strip (22) is heated as it passes through the chamber (35) by hot combustion gases supplied by a burner (37) and blower (40) to a manifold (44) connected to the fluid bearings (62, 54) disposed within the chamber. After leaving the chamber (35) the strip (22) is cooled by air or re-circulated gas supplied by a blower (45) to a manifold (49) connected to the fluid bearings located within the chamber (36).  To improve the heating and cooling of the strip within the chambers (35, 36), fluid from the manifolds is also supplied to conduits extending transversely of the strip and having elongated nozzles for directing a high velocity stream of fluid against the strip.  To remove corrugations occuring during passage through the treatment chambers the strip may be flattened by passage between further fluid bearings located in a liquid filled tank (93), Fig. 12 (not shown) and supplied with liquid e.g. water pumped from the tank.

Abstract: 1459950 Pitch BRITISH PETROLEUM CO Ltd 31 Oct 1974 [12 Nov 1973] 47109/74 Heading C5E A process for the manufacture of binders suitable for use in the production of electrodes comprises distilling a residue obtained from high temperature cracking of a petroleum fraction to give a material having a KS softening point of from 55-90‹ C., and thermally ageing this material to increase the KS softening to 80-100‹ C. The distillation is preferably carried out at atmospheric pressure at a residue temperature of 150-450‹ C. The thermal ageing is carried out by heating the material under reflux, by recycling of the pitch at the bottom of the distillation column or by heating in a reactor at atmospheric pressure. Any light aromatic fraction separated during the ageing is reinjected without altering the ageing temperature. The examples all relate to production of binders from the residue obtained by steam cracking naphtha.
