[Also in Divisions F3 and F41 Oil and/or water contaminated aluminium alloy swarf, from hopper 31, is fed by rotary conveyor 32 and oscillatory conveyor 33 to an indirectly heated rotary furnace (not shown) of the type disclosed in Specification 944, 623 fast oil and water sprays 35, 36 respectively. In the furnace, oil is burned off from the swarf and water evaporated. A temperature responsive control unit 37, controls the amount of oil or water sprayed on to the swarf to prevent overheating within the rotory furnace. Control is effected through proportional temperature controllers CO, CW respectively, which regulate the setting of motorized valves MVO, MVW respectively in the oil and water supply lines to the sprays. Relays R 1  and R 2  respectively prevent spraying whenever the level in hopper 31 falls below that of probe 34, or when conveyor 32 is inoperative. In a modification Fig.2 (not shown) operation of either the oil or the water spray is selected by a manual valve, the sprays then operating for timed controlled pre-selected periods whenever necessary to maintain the furnace temperature at a desired value. In both embodiments, the control unit 37 may also regulate the heat supply to the indirect heating means of the rotary furnace to help control the temperature therein. Alternatively gas or oil burners in the furnace may be used in place of the indirect heating means.

Abstract: 1,232,420. Coding and decoding. SCM CORP. 19 July, 1968 [21 July, 1967], No. 34631/68. Heading H4P. An electro-mechanical register in which numerical information is fed manually or automatically from say a punched tape or a computer, comprises a keyboard, Fig. 18 (not shown), which operates a combination of switches (1, 2, 4, 8) energizing a corresponding number of solenoids which determine the angular rotation in turn of a set of gears acting as a store, which rotation is transferred to print wheels for parallel visual read out. Energization of one or more solenoids 1, 2 &c., Fig. 17, on partial depression of any key moves a corresponding number of stops, e.g. 172, out of the path of sidewardly movable pins 152 of a friction driven paddle wheel 151 which advances a corresponding number of pins when a " go " solenoid 209 is energized on full depression of a key. On release of the solenoid(s) the pins are returned to the inoperative, i.e., left-hand position. Paddle wheel movement is transmitted through gears to an input gear 105 meshing in turn with each of storage gears 37 which are held from rotation in other than the meshing position by a spline on elements 106, 107. Depression of a print key (500) energizes a solenoid (66) which moves the gears into engagement with racks 13, Fig. 1, and also a solenoid (66A) which engages a machine clutch causing a forward, i.e., left-hand movement of the racks which each advance to a position corresponding to the remainder of the travel of the gears 37 to the zero position and hence print wheels 12 are also rotated correspondingly. Solenoids (66, 66A) are held energized for half a machine cycle by a cam-operated switch (560). The printing mechanism may be of known type and on completion of the left-hand movement of racks 13, a paper tape is brought against the type wheels. Subsequently the wheels are restored in zero position on spring return of the racks to their home position. Information may be entered through a remote keyboard or a local or remote punched tape, and machines may be run in parallel. Electrical signals from the switches may be transmitted to a computer also the printer may be controlled from such computer.

Abstract: 1,250,153. Winding webs. JAMES MACKIE & SONS Ltd. 22 Oct., 1968 [2 Nov., 1967], No. 49818/67. Heading B8R. [Also in Divisions D1-D2] To prevent a tape from being crushed by the trailing edge of a traversing device 10 of a package winding apparatus, the tape is fed over at least one guide member 8 that alters its setting relative to the take-up spindle 4 so as to bias the tape 2 to move readily from the centre of the package towards its ends but adapts a fresh setting when the tape is moving from the ends of the package towards the centre of the package, said fresh setting causing a lesser degree of bias or even negative bias to retard movement of the tape sideways. In Fig. 1 the guide member is a round bar 8 in the form of a shallow V pivoted at 14. The tape 2 engages the underface of the bar 8. The bar 8 is rocked by a piston and cylinder unit 56 controlled by co-operating means 52, 54 and 53, 55 on the traverse mechanism. When the tape is returning from the left-hand end of the package the bar 8 is in the full line position with its arm 18 horizontal or slightly sloped downwardly towards the pivot 14. The other arm 18<SP>1</SP> of the bar slopes upwardly. When the tape is returning from the right-hand end of the package the unit 56 operates to rock the bar to the broken line setting in which the arm 18<SP>1</SP> is horizontal or slightly sloped downwardly towards the pivot 14 and the other arm 18 slopes upwardly. Stops 62 define the desired settings of the bar 8. The guide member may be between the traverse member and the package. In a modified construction the guide member comprises two wings mounted on an axis parallel to the spindle 4, the guide member pivoting back and forth in a radial direction to substitute one wing for the other at the ends of the traverse movement, the wings being shaped to give a different degree of bias to the tape during traverse from and to the ends of the package. Traverse mechanism.-The traverse device 10 is coupled to a nut 22 on a traverse screw 24. The screw 24 is driven from a shaft 30, see also Fig. 3 (not shown), through gearing controlled by a piston 42. When the components 52, 54 co-operate the piston 42 rocks a bracket 38 to a setting in which the gear 44 is driven by gear 32 via gear 34. When the components 53, 55 co-operate the piston 42 rocks the bracket 38 to a setting in which the gear 34 moves away from the gear 44 and a further gear (40) driven by the gear 34, engages gear 44.

Abstract: 1,253,133. Testing cigarettes. HAUNIWERKE KORBER & CO. K.G. 20 March, 1969 [25 June, 1968], No. 14649/69. Heading A2C.  In an apparatus for detecting faults in cigarettes or other rod-like articles having an outer wrapper and a permeable filling by passing a testing air current through them whilst they are being transported in a direction perpendicular to their longitudinal axes, the ends of the articles are engaged by sealing means which at at least one end is self-aligning by engagement with said end(s) of the articles. The invention is particularly applicable to the obtaining of a good seal to the filter end of a filter cigarette when the end face thereof is not precisely perpendicular to the longitudinal axis of the cigarette. The apparatus used is basically similar in construction and operation to that disclosed in Specification 1,187,262 for the testing of double length cigarettes, but it makes use of a narrower drum 1 to accommodate single length cigarettes C and bears modified sealing means.  In one embodiment, Fig. 1, the displaceable tubular connector 18 of the said Specification is provided with a short tubular extension to which a rigid concave-surfaced sealing member 42 is attached by means of a flexible tube 41. In a modification of this embodiment, Fig. 2, a connector member 48 (corresponding to member 18) is extended by a guide portion 49 having a ball member at its forward end about which a sealing member 47 can pivot freely. A flexible tube 46 connects the members 47, 48. In further embodiments (Figs. 3-5 not shown), longitudinally-resilient advancement of the connector member 18 and the provision of the flexibly mounted sealing member 42 are replaced by rigid advancement of the member 18 and by sealing members disposed in depressions in the flange 6 connecting with bores 11. In one form, centrally bored sealing members (92) are centrally mounted in individual diaphrams (91) which are clamped around their circumferences in depressions (101). In another form, the sealing members (112) are supported by a single ring-shaped diaphram (111), each member (112) being connected by a flexible tube (115) with a bore (116) corresponding to the bores 11. Optionally, the sealing member (112) may carry a soft elastic ring (113) on its sealing surface.

A facsimile transceiver which utilizes the same optical path for both scanning and writing operations, comprises an arc lamp 10, Fig. 1, lenses 12 and 18, aperture mirror 14 (or beam splitter, Fig. 2, not shown), a rotating reflective prism 20, an aperture 24 and a photo-detector 26. To scan a document 22, the light passes via aperture 16 in mirror 14 and is line scanned across the document by means of rotating prism 20, the document being linearly moved. The reflected and modulated light from the document is reflected by prism 20 through lens 18 on to mirror 14 which reflects it via aperture 24 on to detector 26. In its printing mode the intensity of lamp 10 is modulated by a received video signal, and the modulated light is scanned by prism 20 over photo-sensitive material which replaces document 22, e.g. a xerographic drum or zinc oxide paper. In Fig. 1 (and in Fig. 2, not shown, which utilizes a beam splitter, e.g. a two-way mirror) only 25% of the light from the lamp scans the document and photo-sensitive material. By displacing mirror 14 towards lens 12 when the transceiver is in its printing mode, 50% of the light from the lamp scans the photosensitive material, Fig. 3 (not shown).

An hydraulic brake pressure control valve for reducing the pressure applied to the rear wheel cylinders of a vehicle beyond a certain value, has a stepped piston 12 which has two sections 12a, 12b sliding in respective bores 10a, 10b of a cylinder 10 one end of which is closed by a plug 11 in which a valve member 17 is positioned having a spherical valve surface 17a which engages a conical seat 15a, the valve controlling the hydraulic pressure fed from a master cylinder to the rear wheel brake cylinders via conduits 34, 32, port 31, chamber 16, radial grooves 12c formed on piston 12, chamber 22, port 35 and conduit 14. The front wheels are directly connected to the master cylinder via conduit 33. At low pressures hydraulic fluid passes straight to the front and rear wheel cylinders but on reaching a pressure sufficient to overcome the force of a compression spring 21 acting on piston 12, the piston moves to the left as does the valve member 17 under the action of spring 18 until valve surface 17a seats on valve seating 15a effectively sealing the rear wheel cylinders from the master cylinder. The pressure acting on the shoulder of the larger piston section through a by-pass passage 13 and port 30 then moves the piston to the right to open the valve once more whereupon pressure again acts on the front face of the piston 12 and the cycle of operation is rapidly repeated.

The comparator Fig. 4 (not shown) comprises a delay (21) which delays one of the two outputs sufficiently to bring the pulses in it into coincidence with those in the other output. The two outputs are then applied via an OR-gate (22) to sample the ramp signal in a sample and hold (23). To separate the two pulse trains, the ramp generator output is fed to a pulse shaper which produces two phase displaced pulse trains corresponding to those to be separated, and these operate a bi-stable circuit which controls a pair of gates to feed the two pulse trains to separate output lines. The phase displaced pulse trains may be produced by deriving a single pulse train and feeding it to two separate delays (53, 54), Fig. 6 (not shown). Alternatively, Fig. 7 (not shown), the ramp signal may be applied to two threshold circuits (62, 63) each adjusted to produce pulses when the ramp exceeds a different threshold.
