Patent GB-371101-A (GB)
Abstract: 371,101. Totalizators. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, ENGBLOM, J. F. T., Villa Tomoana, Elm Avenue, Beeston, Nottingham. Feb. 28, 1931, No. 6306. [Class 106 (i).] Ticket-issuing machines to be selectively and individually coupled to the registering equipment are arranged in groups and the selection is effected through chains of relays so that an operating potential is extended first to a particular group and then to the calling machine in that group. As applied to the totalizator described in Specification 368,445 and in the form shown in Fig. 1, the ticket machines are in three groups (or rows) each group being controlled by a relay chain and the particular group being selected by a main chain. Thus operation of a relay ST (not shown) at a ticket machine extends earth at st1 to a relay SA to direct at sa1 the earth from relay CT to the uppermost row of machines and thence through contact st3 to relay A in the machine in question. The other rows are similarly controlled by relays SB, SN having their first contacts in series with contact sa1. The hold-off arrangements of the prior Specification are also applied to the present arrangement to prevent a machine from again operating before waiting machines have been cleared. In a modification, Fig. 2, the groups of machines are each again divided and sub-divided, further selecting relays TA, TB and UA, UB being provided to extend the earth from CT and, say, sa1 to, first, one of three sub-groups as determined by the cascade contacts ta1, tb1 and thence to one of three subdivisions according to the setting of similar contacts ua1, ub1.

Abstract: 924,174. Dry-cleaning apparatus. CONSTRUCTIEWERKHUIZEN EMILE D'- HOOGE P.V.B.A. Nov. 14, 1960 [July 15, 1960], No. 38953/60. Class 138 (2). Dry-cleaning apparatus is provided with equipment for measuring relative humidity this equipment being installed in a circuit which is separate from the usual filtering circuit and controlling the addition of water to the circulating liquid. As shown, the liquid is circulated by a pump 20, the greater part being returned to the machine 1 through a mixing device 24 and the remainder through a vapour chamber 14 and safety device 26. In the mixing device the liquid is thoroughly mixed with any water and soap solution supplied from reservoirs 27, 30 under the control of valves 28, 31. A hair hygrometer 12 connected to the top of the chamber 14 controls operation of the valves 28, 31 through an electrical circuit (Fig. 8, not shown). The hygrometer has three points 35, 36, 37, displaceable over a graduated scale (not shown), the pointer 35 being connected to the hair 38 of the hygrometer. Pointers 36, 37 carry electric contacts and can be adjusted for minimum and maximum values of humidity. An electrically-operated valve 43 supplies dry air to dry out the chamber 14 and hygrometer 12 at the end of each washing process. As soon as the humidity falls to the lower adjusted value the contact carried by pointer 36 is closed and the air supply automatically shut off. The safety device 26 comprises a cup 44 pivoted at 46 (Fig. 6), and counterbalanced by weights and a mercury switch 47. If the flow through a pipe 25 ceases, liquid in the cup 44 drains through a hole 48 and the cup returns to the horizontal position and the switch 47 opens, thereby de-energizing the water and soap supply valves 28, 31. The mixing device 24 includes a jet nozzle 54 and a constricted portion 53 producing a Venturi action. A float device 34 cuts-off the supply of solvent when the required level is reached and also starts the pump 20.

Title: Improvements in or relating to tape loop storage columns
IPC: G11B15/58
Filed: 1962-10-17
Abstract: 961,022. Photo-electric position determination. AMPERE CORPORATION. Oct. 17, 1962 [Nov. 1, 1961], No. 39367/62. Heading G1A. In a tape-loop storage column for a magnetic tape recording device the length of the tape loop in the column is sensed by a photo-electric or other radiation sensitive device. Fig. 1 shows a typical tape transport system in which tape passing between reels 12 and 13 is fed through tape loop storage columns 16 and 21 provided on either side of head assembly 18. These columns allow rapid acceleration and deceleration of the tape moving past the heads. The tape loop length in them is sensed and the signals used to control the reel motors in such a way as to maintain the loop lengths as nearly as possible constant. According to the invention sensing of the tape loop length is effected by collimating light from a lamp 43 by means of lens 53 and directing it by means of a plane mirror to illuminate uniformly the whole length of a transparent window 33 extending up the side of the column. The face of the window is faceted as shown and has faces parallel and perpendicular to the light beam. That part of the beam which is not cut off by the bottom of the tape loop 54 passes into the window and after total internal reflection at the rear surface 63 is directed to photo-cell 39 to give a control voltage on line 40. The window 33 is set back slightly in a slot in the side of the column so that its facets do not interfere with smooth tape movement. The lens 53 and plane mirror may be replaced by a concave collimating mirror (Fig. 7, not shown) and the back wall 63 of the window curved to enable a reduction in window thickness to be made (Fig. 6, not shown).

A roll-forging machine comprises a frame 11 and a roll carrier 12 mounted on a sleeve 28 carried by an eccentric 24 on a drive shaft 20, the sleeve 28 having a pinion 27 which cooperates with a ring gear 26 such that a roll 31 mounted on the carrier moves in a non- circular path. In the preferred embodiment the teeth ratio of the pinion to the ring gear is 5 to 6 so that the locus of the roll 31 is an hexagon with curved vertices, Fig. 4 (not shown). A pair of carriers having co-operating rolls may be used to roll sheet or, as shown in Fig. 3, four carriers comprising two perpendicular pairs operated interdigitally may be used. The rollgap may be adjusted by moving the carriers toward and away from each other by means of two eccentric rings 65, 66 mounted one within the other and rotated by cylinders 67, Fig. 10, or other suitable means, such as screw-downs or wedges. Alternatively the gear ring may be rotated by means of a lever which alters the angle at the flattened part of the roll locus, e.g. one of the sides of the hexagonal locus of the preferred embodiment, so that the roll engages the work at a greater or lesser angle thus giving a greater or lesser reduction, Figs. 8A, 8B (not shown). A means of altering both the roll locus and the separation of the roll carriers, Fig. 12, has the ring gear secured to a plate 82 pivoted on the frame 11 and the ring gear surrounded by an eccentric ring 85 on which a worm gear 86 is mounted. The worm gear is driven by a worm 87 so that as the carrier is moved away from the roll gap the ring gear is also rotated by a fixed pivot 83 attached to the plate 82. When two pairs of roll carriers are used all may be adjustable or only one of each pair. The roll carriers are driven from a common drive shaft through universal joints where the roll carriers are moved bodily, Figs. 9 and 11 (not shown).

A propellant charge 3 comprises an organic fuel mixed with an inorganic oxidant, pellets 4 of faster burning material being embedded in the charge in a regularly spaced pattern, the volume of each pellet being small in comparison with the volume of the charge. The rocket motor of Fig. 1 has a combustion chamber 1 lined with an inhibitor 2 and provided with an exhaust nozzle 5 within which is an electric igniter 6. The propellant may be composed of polysulphide and ammonium perchlorate or polybutadiene and ammonium perchlorate and the pellets may be black powder with a burning rate about 100 times as high as the propellant. With the arrangement of Fig. 1, the propellant on ignition burns end-wise until the combustion surface reaches the first pellet 4. This pellet then burns out leaving a recess in the burning surface, so that burning then takes place radially as well as end-wise. This process is repeated as the combustion surface travels along the motor. Instead of one axially arranged row of pellets 4, there may be five rows symmetrically arranged, Fig. 8. The pellets may be of uniform length and arranged at equal distances apart or the pellets may be longer and nearer together towards the nozzle. To provide a larger initial burning surface the nozzle end face of the charge may be recessed. To make the composite charge, cylindrical blocks 3a of propellant are machined or cast with an axial hole 12 into which a pellet 4 is placed with a tight fit. The blocks 3a are then bonded together with discs 3b of propellant sandwiched between until a cylinder of the required length is obtained. This is then placed in a tube 2 of inhibiting material and propellant in a liquid state is poured into the space around the cylinder.
