Title: A method of and apparatus for conveying sheets from one location to another
Inventor: BEK STEEN JACOB
IPC: B65G57/04
Filed: 1963-11-14
Abstract: 975,889. Feeding sheets. F. L. SMIDTH & GO. A.S. Nov. 14, 1963, No. 45083/63. Heading B6B. Sheets are conveyed from one position to another, such as from one pile to another pile, by a lifting device having at least one member for gripping the sheets, each point of the lifting device tracing a cycloid lying in a vertical plane and having a downwardly facing concavity and a vertical axis of symmetry. The cyloid may be curtate, in which the extension constitutes from 5 to 10% of the radius of the rolling circle of the cycloid. As described, the pile 1 comprises fibrous cement sheets alternating with separator sheets of steel &c., and the object is to place all the cement sheets on a pile 2, and all the separator sheets on a pile 3 by using two suction gripping members 25, 26 which have suction openings about the same size as the sheets. The piles rest on supports 4, 5, 6 carried by columns 7 which are hydraulically or pneumatically raised or lowered so the top sheets in the three piles are always at the same level, which is the lower working position of the suckers 25, 26. Four fixed columns 11 carry two members 10 on which a carriage 12 can be horizontally reciprocated by the rod 13 of a compressed air cylinder 14. The carriage 12 has four toothed wheels 15 which roll on racks 16 on the members 10, and a lifting frame 19 has draw-bars 18 journalled on crank-pins 17 which are mounted at points on the wheels just outside the peripheries of the rolling circles of the wheels. The arcs of the pins 17 thus describe curtate cycloidal paths 30, Fig. 2, and hence the lifting frame 19 and the suckers 25, 26 carried thereby also follow the same path. The suckers 25, 26 are connected by draw-bars 24 to yokes 23 which rest on the frame 19, the mating faces of the yokes and frame being ribbed. When a sucker rests on a pile, the frame 19 descends slightly lower so that the sucker can find its own level to accommodate irregular-shaped sheets. The sucker 25 lifts and deposits cement sheets, and the sucker 26 does likewise with the separator sheets, and they are connected by bellows 27, 28, respectively, to a suction fan 29. Where the sheets are corrugated, the lower outer edges of the suckers are similarly shaped. In a modification (Fig. 4, not shown), cement sheets are in two separate abutting piles, each separator sheet is common to both piles; and the cement sheets are separated to form two spaced piles, by providing on one -head double suckers which are close together when they pick up cement sheets from the abutting piles, and are then separated from each other prior to depositing the sheets. The double suckers are supported on a cross-frame, and are relatively displaceable by compressed - air cylinders. Where all the sheets in a pile are of ferromagnetic material, the suckers are replaced by magnetic heads.

Title: Device for measuring neutron flux
Inventor: BRAUN JOSEF
IPC: G01T3/00
Filed: 1963-11-15
Abstract: 1,067,251. Detecting neutrons. ATOMENERGI A.B. Nov. 15, 1963 [Dec. 14, 1962], No. 45296/63. Heading G6P. A neutron flux measuring probe consists of a slow neutron detector, enclosed in an inner moderator layer, an intermediate absorber layer and an outer moderator coating. The resultant sensitivity curve corresponds to the human organism response which is more sensitive to fast than to slow neutrons. The absorber permits the flow of fast neutrons to the detector which restricts the flow of incident slow neutrons. After passing through the absorber the fast neutrons are moderated in the inner layer and are registered by the detector. The absorber layer may be perforated to permit the passage of some slow neutrons. The fast neutrons, although reduced in speed by the outer medeator layer retain sufficient velocity to traverse the absorber.

Abstract: 1,168,972. Protective systems. ROBERTSHAW CONTROLS CO. 21 Oct., 1966 [23 Oct., 1965 (2)], No. 47347/66. Heading H2K. A fail-safe motor protective arrangement has a controlled rectifier 16 with its gate-cathode circuit connected between the centre tapping of the secondary winding of a transformer 24 and a point 58 in a resistance network which includes a temperature sensitive resistor 52 positioned in the windings of the motor 10. A standing bias for the gate of the rectifier is provided by resistors 30, 32 so that the rectifier 16 normally conducts on alternate half cycles and energizes a relay 26 to maintain contacts 40, 42 closed. In the event of overheating the resistance of the resistor 52 increases causing the point 58 to go negative so that the rectifier 16 ceases to conduct. The relay 26 opens its contacts 40 to cause a main contactor 12 to open and opens its contacts 42 to remove a short circuit from a resistor 64 in the resistance network. This last action increases the operating differential so that a considerable drop in temperature must occur before power is restored to the motor. To ensure adequate protection against single-phasing, a further temperature responsive resistor 68 may be connected as shown.

Abstract: 954,347. Laminating. MONSANTO CHEMICAL CO. Dec. 17, 1962, No. 47440/62. Heading B5N. Articles, e.g. disposable food containers, of thermoplastic material are formed by treating the appropriate surfaces of sheets of the thermoplastic material with a corona discharge, bonding said surfaces together by pressure alone, and moulding said article from the laminated sheet thus formed. Thermoplastic materials which may be used include oriented polystyrene, oriented or unoriented polyethylene, rubber hydrochloride, and vinylidene chloride. With reference to Fig. 1, sheets 1, 2, of biaxially oriented polystyrene are withdrawn from rolls 3, 4 and subjected, on their appropriate surfaces, to a high voltage, high frequency, corona discharge from electrodes 8 and 9 in chamber 5. The sheets are bonded, at ambient temperature, by rolls 10, one of which is preferably of an elastomeric substance. The articles are then formed and separated from the sheet by press 11, the two component sheets being reclaimed by bending the scrap sheet sharply round rolls 12 and 13. The article thus formed may contain inserts for decoration or strengthening purposes which have been treated by a corona discharge, and which are bonded between the two surface sheets during the above laminating process. More than two sheets may be bonded together as in Fig. 3, not shown.

Abstract: 1,029,830. Ventilators. COLT VENTILATION & HEATING Ltd. Dec. 18, 1963 [Dec. 18, 1962], No. 47843/62. Heading F4V. [Also in Divisions A5 and F2] Two hinged cover-plates of a roof ventilator are normally held closed and are automatically opened in the event of fire acting on fire-detecting means. As illustrated, the roof ventilator comprises a throat 14, fixed side baffles 23 and end plates 15, and overplates 17 hinged at 18. The plates are normally held closed by cords 27 connected to a further cord by a link which fuses in the event of fire to allow springs 26 to move the plates to the fully open position. Side openings 20 of the ventilator are controlled by closure plates 29 pivoted at 30 and biased to the closed position by springs 31. The closure plates are normally operated by pneumatic piston and cylinder assemblies 32 supplied from a common compressed air source, Fig. 6 (not shown). The air line includes a connection to atmosphere, Fig. 7 (not shown), which is normally closed but which in the event of fire opens to allow the springs 31 to close the plates 29 and also to shut off the compressed air supply. In an alternative arrangement, Fig. 8 (not shown), springs 62 bias the cover plates 17 to the open position, this bias being over-ridden by springs 60 including fusible links 61. The plates 17 may be independently operated by pneumatic cylinder and piston assemblies 63, the plates 17 being held in engagement with the piston rods 64 by the springs 60. A manual valve 43 allows compressed air from a source 40 to open the plates or connects the cylinders 63 to atmosphere to close the plates. A valve 38 similarly controls the closure plates 29. A further valve 39 in the air supply to the piston and cylinder assemblies 32 is connected to the supply to the assemblies 63 so that when valve 43 passes compressed air to open the plates 17 compressed air is allowed to escape from assemblies 32, thus closing the plates 29 and vice versa. As described above, in the event of fire, the plates 17 open and the plates 29 close. In modifications, not shown, the cover plates 17 may be biased to open by weights and the means detecting the presence of fire to open the cover plates may be a device responsive to thermal radiation, rate of charge of temperature, light or sound.
