Title: Glasslike cellular material prodn - by heating/expanding mixture of glass-like base material,metal oxides,minerals and gas rel
IPC: A61L17/12
Filed: 1972-02-07
Abstract: Glass-like cellular material is prepd. by grinding a glass-like base material, one or more metal oxides, and materials, and adding, before, during or after grinding, one or more materials from which one or more gases is released, during subsequent heating and/or chemical treatment and/or physical treatment. The amounts of gas releasing material and of base material, and their ave. diameters are related by the expression: B/6G = (g + 2b)3-g3/y3 = B/G (where g is the ave diameter of the gas releasing material particles; b is the ave diameter of the base material particles; G is the vol. of the gas releasing material; and B is the vol. of the base material particles, exposed in the same units). Method ensures that the base material surrounds the gas releasing material particles, and is expanded by the released gas.

Title: Mechanical handling trolley which swings large steel slabs - from a horizontal to a vertical position for loading into a furnace
IPC: F27D3/00
Filed: 1975-02-04
Abstract: In a plant for handling a slab between a roller conveyor and a furnace, in which the slab stands on edge on the hearth, at least the central part of the hearth can be removed by a hoist for loading or unloading the slabs into and out of the furnace. A trolley fitted with a horizontal pivot shaft for a slab support is used consisting of gps. of fingers located in two planes of a dihedral right angle, the support being driven so the slab is swung from a horizontal to a vertical position, and the spacings between the fingers in one group match the spaces between the rollers in the conveyor. The spacings between the fingers in the other group match the gaps between blocks used to support the slab on the furnace hearth. Large slabs with wt. of several tonnes are thus more uniformly heated if they stand on edge in the furnace. The plant is used to swing the slabs to a vertical position.

Title: Heart section display system - used binary quantised picture signals and has flip-flop controlled by centre line pulses and contour signal
IPC: A61B6/00
Filed: 1976-02-09
Abstract: The heart-shadow section display system displays the correct contours of the heart using binary quantised picture signals as video signals. Centre line pulses are applied to the sitting input of a flip-flop (16) and the contour signal (17) to its reset input. The flip-flop output is passed to a pulse shaper (20) that produces a pulse from one edge. This pulse is delayed (21) by one line and returned to the flip-flop other reset input as a limiting pulse. The delay circuit is controlled by a regulator (24) whose control voltage is derived from a time comparison of the flip-flop output, the contour signal (17) and the limiting pulse (22).
