Title: Apparatus for developing a thermo-developable photographic medium
IPC: G03D13/00
Filed: 1968-10-02
Abstract: 1,241,421. Photographic heat developing apparatus. SCOTT PAPER CO. Oct. 2, 1968 [Nov. 6, 1967], No.46812/68. Heading G2A. The apparatus includes a developing chamber through which sheet material (21) Fig. 4 (not shown) is fed by roll pairs 40, 42 and 60, 62; thermostatically controlled radiant heaters 88 within the chamber for uniformly heating and developing a sheet (21); and an air-flow system which causes air to flow evenly over both surfaces of a sheet (21) and entrain chemical components driven thereform by the heating, which components are removed from the chamber through ducts 102, 104. These ducts are connected to an exhaust fan and have adjustable intake slots 112, 114. The air is supplied to the chamber through ducts 90-93 each having one row of air intake apertures 94 and two rows of air outlet apertures (95). After developing, the sheet (21) is fed by rolls 60, 62 to a guide 66 and thence to a tray 64. (For Figure see next page)
Patent GB-468381-A (GB)
Abstract: 468,381. Totalizators. HANDLEY, J., SUCKLING, C., and SUCKLING, R. H. Jan. 2, 1936, No. 141. [Class 40 (i)] In a totalizator in which bet signals are collected from a plurality of ticket issuing machines through the intermediary of an assigning switch, the contacts of the switch are connected to the machines and the wiper is adapted to move quickly over the contacts of unoperated machines and slowly when in engagement with machines waiting to transmit bet signals. The Figure shows a ticket issuing machine 3 associated with an assigning switch 31 and " win " and " place " runner and totals counters. When the machine is operated to transmit a bet signal and issue a ticket, a member 11 is operated into engagement with a pawl 9 and wiper 32 connects battery 33 to operate a magnet 6 on the assignor individual to 'the machine. When the wiper 1 moves into the region of influence of the magnet 6, a pawl 4 is operated by the armature of magnet 6 to clutch the wiper 1 to a wheel 5 which is rotating at a slower speed and thus allow the wiper 1 to remain in engagement with contact 2 for a relatively long period of time. Wiper 1 energizes magnet 7 in the machine to allow wipers 14, 15, 21, 23, 32 to move one step. In this position, the magnets 6, 7 are held operated over wipers 23, 32 and contacts of relay 13 from battery 37. The bet signal is transmitted over wiper 15 and " win " and " place " switches 17, 18 to the counters 19, 20 and a relay 13 is pulled up over wiper 14. The relay 13 is timed to maintain closed the circuits of magnets 6, 7 for a period sufficient to allow the transmission of the bet signals. When the signal is accepted by the '' horse " counter 20, an impulse is reverted over contacts 22 and wiper 21 to operate magnet 8 which permits further operation of the machine to issue the ticket when the magnet 7 is released by the relay 13. The counters are of the two-step type operated in response to the energization and de-energization of the stepping magnet and the checking impulse is reverted during the first step. A relay 24 is provided for each set of runner and totals counters and remains inoperative provided a runner and the totals counter operate together. If, however, only one counter functions, relay 24 pulls up to operate a signal lamp 26. A relay 25 also is operated to prepare the circuit of a relay 27 which is pulled up in the event of a second faulty operation. Specification 412,675, [Group XIX], is referred to.

As illustrated in Fig. 1, the vessel has an open front and a partly open bottom. The remainder of the bottom is perforated at 51a to allow egress of water. The oil layer forms a wedge 55 above a baffle 26 and in front of the stern wall 12 so that removal of oil through a pipe 24 is facilitated. As illustrated in Fig. 3, the bottom of the vessel is wholly open and oil is admitted through a slot 57a in a wall 57. The stern wall 12a is inclined to increase the thickness of the wedge 55. The vessel may include vertical perforated partitions, Fig. 6 (not shown), to reduce wave motion within the vessel. In another arrangement for reducing wave motion in the vessel, a deck floats on the surface of oil in the vessel, Fig. 4 (not shown). The baffle and the oil withdrawal pipe or a pump are mounted on the deck. The vessel may be powered or may be towed.

Apparatus for cutting and trimming books 5, Fig. 1, or the like comprises a conveyer 7 for delivering the books to a saw 2, and retaining means 9 which resiliently urge the books against the conveyer through at least a substantial part of the movement of the books. The books, which may be in double form, are initially stored in a magazine 4 and fed singly by a feeding device 6 on to the conveyer 7 of the clamping device. The conveyer has abutments 7a which engage the books, and may act in place of the device 6 to remove the books from the magazine to convey them between guides to the saw 2, the books being clamped against the conveyer by belt or chain 9 which has sliding runners or rollers 10 and is resiliently mounted so as to be adaptable to the thickness of the books. The saw 2 separates the double books into single books 5b which pass down a shoot 11 on to a stacking magazine 12. In another arrangement, the double books 5, Fig. 4, are delivered from a feeding station Z to a trimming station I whereat saws 2 trim the ends of the books before they are passed to a separating saw 2 at a station II. The separated books then pass grinding wheels 2a at a station Ia so that the trimmed edges of the books are smoothed. After trimming the books are conveyed past a saw 2 at a station III and a grinding wheel 2a at a station IIIa for the cutting and smoothing of the longitudinal edges of the books. Finally, the separated books are fed past grinding wheels 2a at stations IIa, IIb for smoothing the edges produced by the saw 2 at station II.

The sulphide capture layer consists of a polyolefin containing at least one powdery metal, metal salt, oxide or hydroxide which reacts with water soluble sulphides to produce water insoluble metal sulphides, thus preventing the growth of tree-like sulphide crystals through the insulation of the cable which could cause premature dielectric breakdown of the insulation. The added metals may be zinc, cadmium, silver, cobalt, strontium, bismuth, gold, tin, iron, copper, lead, nickel, antimony, manganese, vanadium, tellurium and the metal salts may be sulphates, chorides, nitrates, carbonates and aliphatic and aromatic organic acid salts of the aforementioned metals. Thepolyolefin may include high density polyethylene, medium density polyethylene, low density polyethylene, ethylene vinyl acetate copolymer, ethylene ethylacrylate copolymer, polyolefin, ionomer, isotactic polypropylene and isotactic butene-1. The sulphide-capture layer can be in any desired position relative to the core and insulation and the sulphide-capture additive could be incorporated into a semi-conducting layer or plastics sheath with a polyolefin-series resin base. A composite cable consist of many cores all being protected either separately or commonly by a sulphide capture layer, for example, as shown there are 3 conducting cores 101 each surrounded by insulation 103 and stranded together with a filler 104.
