Patent CA-1082253-A (CA)
Inventor: BERZENYE MICHAEL L
IPC: B66C1/12
Filed: 1979-06-20

Abstract: Abstract Prior art slings used in stevedoring operations have had protective coverings, such as canvas fire hoses, but they have been unsuccessful in that they become loose and slip to expose the material being lifted directly to the wire rope which cuts into the material,  These wire rope slings are used, for example, to lift large rolls of low carbon steel rods or wire.  This invention is a wire rope sling having a high abrasion resistant plastic, such as urethane, over the portion of the sling that comes into contact with the material being lifted.  The wire rope is coated with the plastic by a method which causes the plastic to be embedded in and around the surfaces of the wires so that it is permanently fixed on the sling and does not slide or break off.  The coating is thick enough and hard enough to withstand the maximum load of the wire rope without damaging the load material or the coating.

Abstract: ABSTRACT     The invention relates to a process for the preparation of anhydrous magnesium chloride from magnesium carbonate preferably magnesium carbonate ores such as magnesite.  The process comprises reacting solid magnesium carbonate pieces preferably screened ore in a packed bed reactor comprising the magnesium carbonate pieces with gaseous chlorine in the presence of carbon monoxide at a temperature above the melting point of magnesium chloride and below 1200°C.  The off-gas predominantly carbon dioxide is withdrawn from above the packed bed and molten anhydrous magnesium chloride is withdrawn from below the packed bed.  The invention provides a process having low energy requirements which can be applied industrially on a continuous basis using simple apparatus.

Abstract: Abstract:     An apparatus for separating and transporting flexible sheets from a stack to a processing unit comprises a frame with a vertically movable bottom which carries the stack and over which an up-and-down movable system is mounted to which pick-up heads are fixed over a stack edge.  The stack is compressed and a sheet is picked up near at least one sheet edge by the pick-up heads which have pressure shoes. Thereafter the picked-up sheet edge is slightly tightened between the pick-up heads by which it is lifted from the stack.  Subsequently the partially lifted sheet is removed from under the pick-up heads by means of horizontally moving removal elements.  The lifted sheet edge is gripped by the removal elements and is carried away be them in a horizontal direction at least beyond the pick-up zone, the sheet being progressively turned and rolled off the stack and transported towards a registering machanism.

Abstract: ABSTRACT OF THE DISCLOSURE         An assembly for drilling a hole in a roof to a greater depth than the height of the chamber therebelow includes a starter-driver bar having a first end adapted to be driven by a motor and a second end having a female socket therein, a rod extension including a male end shaped to be received in said female socket and a female socket at its other end of the same cross-sectional size and shape as the first named female socket, and a bit having a male shank of the same general cross-sectional shape as said male end.  The male shank which is received in the socket has a pair of opposed longitudinal grooves in its outer surface extending from its lower end to a point beyond the socket.          The starter-driver bar and rod extensions have axial holes therethrough so that a suction or water can be provided at the lower end of the assembly.  When a suction is to be applied the sockets have at least one hole through its wall which is not covered by the drill shank, but which is covered by the male end of the rod extension.  When water is to be applied this hole is omitted and the water passes through the longitudinal grooves in the bit shank.  A starter hole is first drilled using the starter-driver with the drill bit in its top and a motor connected to its lower end.  Drilling then is continued with an assembly consisting of a first rod extension between the bit and starter-driver.  Additional rod extensions are inserted between the starter-driver and the bottom rod extension until a hole of the desired depth is obtained.

Abstract: ABSTRACT;           In a cathode-ray tube for displaying coloured pictures comprising in an evacuated envelope means to generate a number of electron beams, a display screen comprising a number of regions luminescing in different colours, and colour selection means comprising a large number of apertures which assign each electron beam to luminescent regions of one colour.  In the colour selec-tion means a magnetic quadrupole field is generated to form a magnetic quadrupole electron lens in each aperture. The luminescent regions have the shape of substantially parallel strips the longitudinal direction of which is substantially parallel to the defocusing direction of the quadrupole lens.  The apertures are elongate, substan-tially hexagonal and symmetrical relative to their longi-tudinal axes and are situated with their longitudinal axes in a number of parallel rows which extend substan-tially parallel to the strips and the apertures of two juxtaposed rows are shifted relative to each other.  It is possible, in spite of the large transmission of the colour selection means, to obtain a display screen having very uniform phosphor strips.

Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus is provided for cutting and holding a piece of wire cord. The apparatus comprises a conveyor which includes a plurality of plates for movement in a first direc-tion and a plurality of holding blocks wherein each of the molding blocks is mounted on a corresponding one of the plates. Each of the holding blocks has a fixed portion and a slidable holder portion, the slidable holder portion being slidable relative to the fixed portion. An advancing device advances the cord a predetermined length in a direction perpendicular to the first direction,and a cutter is positioned downstream of the advancing device for cutting the wire cord into cut portions of the predetermined length. A loading device is positioned downstream of the cutter and is operatively coupled thereto for engaging a holder portion of one of the holding blocks to prevent the movement of the holder portion in the first direc-tion, while the fixed portion is moved in the first direction to thereby cause a relative sliding movement between the holder portion and the fixed portion. This forms a space between two adjacent holding blocks having a width at least as great as the width of the wire cord. The loading device pushes the cut cord into the space and releases the holder por-tion such that the holder portion slides in the first direction whereby the cut wire cord is held between the holder portion of one of the holding blocks and the fixed portion of an adjacent holding block.
