Abstract: 1,054,183. Discharging material from a bunker. SIMONACCO Ltd. April 6, 1964 [April 10, 1963], No. 14262/63. Heading B8E. Material from a bunker 12 is discharged by a device which moves along the bottom of the bunker to create a moving hole through which discharge takes place. Thus bunker 12 is formed with a flexible belt 24, and is equipped with a discharge trolley 28 operated by cable 51, and includes a discharge belt 44. Trolley 28 is moved from left to right so that it engages and raises the parts 25 of flexible belt 24 to create lateral apertures through which the material flows and discharges on to the discharge belt 44.
Patent GB-1054317-A (GB)
IPC: H03K3/282
Abstract: 1,054,317. Transistor multivibrator circuits. RADIO CORPORATION OF AMERICA. Dec. 12, 1963 [Dec. 19, 1962], No. 49187/63. Heading H3T. A transitor multivibrator has a voltage for the base electrodes provided from the variable tap on a potentiometer having one end connected through opposed diodes to respective collectors. In the multivibrator shown, the timing resistors 19, 20 are connected to an emitter follower 25 having its base connected to the collector electrodes of the transistors 10 and 14 through diodes 21, 22. Only the diode connected to the non-conducting transistor is conductive so that the voltage applied to the base of the emitter follower and thus to the timing resistors is a portion determined by potentiometer 23 of the full collector supply voltage applied to the point 32. Variation of the potentiometer tapping varies the oscillation frequency. The emitter follower prevents both transistors saturating together when first switching-on since the decreasing potential at the collectors will be transmitted via the diodes and the emitter follower to the bases preventing saturation until sufficient unbalance occurs for the oscillator to start.

Patent GB-1229937-A (GB)
IPC: G03B27/50
Filed: 1968-09-25
Abstract: 1,229,937. Photographing documents. W. VINTEN Ltd. Sept. 25 1968, No.45572/68. Heading G2A. An original document is conveyed through an exposure station by a drum 14, and copied on to a continuously moving film in a magazine 44 which is detachable as a complete unit from the remainder of the copying machine, the film transport means in the magazine being drivingly connected with the drum. As shown, an original document 76, which may be a single sheet or a continuous web, is fed into the machine along a tray 74, and passes round a continuously driven drum 14, against which it is held by rollers 72, through an exposure station 84, and is discharged again on to a collecting tray 78. The drum is connected via gearing 20, 22 and an electromagnetic clutch 26 to a worm-and-pinion gear 30 which drives a shaft 34, this driving in turn a film transport roller 36 in magazine 44. A continuously energized lamp 80 illuminates the original as it passes a transparent strip 84 of a shield 18, the image being reflected via mirrors 40,42 through a lens system 46 on to a continuous roll of film carried by roller 36. The light rays can be interrupted by a shutter S. A particular application of the machine is to the photographing of betting slips, and for this purpose a clock 50 is included in the machine, illuminated intermittently by a flash lamp 51, its image being reflected on to mirror 42 by a further mirror 52 so that it is recorded on the film at the same time as the original document. The drum 14 has peripheral grooves 70, into which extend fingers 69 fixed to an arm 68. When a document passes on to the drum, it engages and lifts the fingers out of the grooves, which causes arm 68 to pivot. A flag 66 at the end of arm 68 normally interrupts the path between a light source 62 a photo-transistor 60. When arm 68 pivots, flag 66 moves out of the light path, so that transistor 60 is illuminated and emits a signal. This energizes lamp 51 to illuminate the clock, open the shutter S, and at the same time causes the clutch 26 to engage, thus transmitting the drive from the roller to the film transport. After the trailing edge of the original has left the fingers 69, they can re-enter grooves 70, thus closing shutter S again, and disengaging clutch 26 so that the film transport is stopped. When the magazine 44 is mounted on the wall 10 of the machine, to which it can be locked, a frustro-conical socket in the roller 36, Fig. 4 (not shown) fits on to a correspondingly shaped head (122) on an end of shaft 34 extending through wall 10. A bolt (140) passes through a bore in roller 36 and threads into the frusto-conical head, thus locating the magazine correctly, and also drawing the two frusto-conical surfaces into frictional driving engagement.

Abstract: 1,259,052. Electric battery. ESB Inc. 13 April, 1970, No. 17457/70. Heading H1B. A rechargeable electric cell comprises a negative electrode can 24, e.g. zinc, an insulator 29 lining the bottom, a laminated separator 26 lining the inner vertical walls of the can, a current collector 25, e.g. a carbon rod disposed in the can having a metal cap terminal 28 thereon, an azodicarbonamide depolarizer mix 27 filling the space between collector 25 and separator 26 to a distance below the top of electrode can 24, sealing means having a central aperture for collector 25 for sealing the open end of the can, so as to leave an air space above the depolarizer mix and below the sealing means, insulating means surrounding the collector in the air space, and vent means. In the embodiment shown in Fig. 1, the sealing means comprises a seal washer 31, e.g. kraft paper, covering the open end of the can which supports a sealing compound 32. An insulating cap washer 33 is provided on sealant 32, and a thin vent washer 42, e.g. a laminated construction of kraft paperpolyethylene-kraft paper, is provided on cap washer 33. The outer metal casing 21 and insulating liner 22 are crimped over the edges of metal cap 28 and vent washer 42. Gases produced in the cell enter porous carbon rod 25 and collect in area 40 under cap 28 and then escape through the crimped edge along the vent path provided by washer 42. The insulating means 34 surrounding collector 25 in the air space is preferably polyethylene. Separator 26 is preferably a laminate of "Cellophane" (Registered Trade Mark) 38, and an ethylene/vinyl acetate copolymer 39 having a gelling agent therein, such a starch wheat flour. Bottom insulator 29 is preferably a laminate of paraffined kraft paper 30 and non-conductive inert plastics material 35 such as polyethylene. In an alternative construction the sealant, vent washer and insulation about the carbon rod in the cell air space are combined in a onepiece polyethylene closure 49 (Fig. 3). Venting is accomplished through holes 52 and grooves 53. Gas passes from the cell interior through holes 52 into space 40 below cap 28 and flows in groove 53 and escapes through the crimped edge of casing 21. Closure 49 has central opening 56 for the carbon rod and a tubular projection 46 depending from the top, which projection surrounds and insulates the carbon rod in the cell air space. The side walls of the closure extending down from the flat surface are threaded at 55. The tubular projection may have a hole therein to permit gases to flow into the carbon rod.

In one form of combustion assembly E, the comminuted refuse from rotary feeder 24 is burnt in a fluidized bed 32 of sand particles to which limestone or dolomite may be added to reduce acid vapour formation. Sewage sludge may also be supplied to and burnt in the bed. Air from compressor 20 supplied through duct 25 both fluidizes the bed and supports combustion, the hot gases produced passing through particle separators 36, in the form of inertial separators, electrostatic precipitators or mat filters, to the drive portion 37 of the turbine. Fine ash from separators 36 and larger inert residues from combustion chamber 31 are discharged to a residue chamber 35'. Alternatively Fig. 6 (not shown), a forced draught fan may supply combustion and fluidizing air to the bed, the air from the compressor being indirectly heated in tubes traversing the fluidized bed, before passing back to the drive portion of the turbine. At least part of the filtered inlet air 21 entering the compressor 20, is drawn from the vicinity of the receiving, shredder and drier assemblies A, B, C, and as this air is subsequently heated any noxious vapours are consumed. A part 19 of the hot turbine exhaust gases is supplied to rotary drier C, the remainder generating heating or process steam, or steam for desalinization, in a boiler 38, prior to discharge. The compressor may provide a vacuum for drawing refuse through underground pipe-lines (not shown) to the receiving assembly A. Alternatively Figs. 7 to 9 (not shown), the combustion assemblies may be of the gasifier type disclosed in Specification 1289143.
