Abstract: 1,226,268. Thermal regenerators. GENERAL REFRACTORIES Ltd. 23 Feb., 1970 [21 June, 1969], No. 31474/69. Heading F4K. In a regenerator chamber 1 comprising a checkerwork area 6 supported above the floor 2 by a number of spaced, parallel vertical support walls 7, and an air inlet and waste gas outlet opening 4a, the base of the chequer area is stepped to provide therebelow a space which converges away from the air inlet/waste gas outlet opening 4a. The top of each support wall 7 which is likewise stepped comprises courses of cross-chequer bricks 8, 10 spaced by filler bricks 9 and a final course of longer cross-chequer bricks 11 which bridge adjacent support walls; the bricks 11 are spaced apart by filler bricks 12 having curved sides. The or each support wall 7 in line with the inlet/exit opening 4a stops short of the regenerator wall 3 at its base but meets the wall higher up (see Figs. 4 and 5, not shown). The opening 4a leads to a flue 4 which in turn leads to an air valve and a chimney.

Abstract: 1,233,609. Measuring distance photo-electrically. HUGHES AIRCRAFT CO. Sept. 20, 1968 [Oct. 17, 1967], No.44746/68. Heading G1A. The distance between a reference point and an object is measured by generating a beam of light and splitting it into a plurality of spatially separated secondary beams; sequentially interrupting said secondary beams; focussing the uninterrupted secondary beams on a focal plane, the images of said uninterrupted secondary beams on said surface being substantially coincident when said surface coincides with said focal plane, and separate when said surface does not so coincide; nutating the light reflected from said images over a receiving reticle in synchronism with the interruption of said secondary beams; directing the nutated light beams passing through said reticle to an optical detector to produce a pulsed waveform; measuring the phase of the detector output pulses, with respect to a fixed reference phase to indicate the distance between the object and the focal plane. Light from a continuous wave laser 10 is formed into an annular beam by an arrangement of reflectors 13 and focused by an annular lens 16 on to an object 11. Lens 16 includes a cruciform reticule 17 so that the image formed on object 11, although a spot when the object is at the focal plane of lens, is in the form of separated sector shapes, when out of focus. The sectors are sequentially obturated by a rotating chopper 14. The reflected image from object 11 is nutated around a cruciform aperture 23 by plate 20 which is so synchronized with the chopper 14 that when the object is nearer than the focal plane the leading sectors appear on the detector 19 whereas when it is farther away the trailing sectors appear. The phase of the detector pulses d to aperture 23 is thus dependent upon the position of the object. A gantry similar to that disclosed in Specification 1, 156, 969 may be provided so that the whole apparatus may follow contours of e.g. a motor car mock-up.

Abstract: 1,265,175. Magnetic recording member. NATIONAL CASH REGISTER CO. 27 Nov., 1969 [9 Jan., 1969], No. 58008/69. Heading H1H. [Also in Division C7] A magnetic recording member includes a thin film (10,000  or less) of substantially metallic magnetizable material overlaid with a thin film of non-magnetic oxide(s) of the magnetizable material bearing an adsorbed lubricant layer (10-3600  thick) than the oxide layer, which is formed directly on to the magnetic layer. The lubricant provides a surface having a lower coefficient of friction than that of the oxide surface. The magnetic layer may be Co-P alloy, and the oxide layer may be formed by heating the Co-P surface to 200- 290 C. In one embodiment, an aluminium alloy disc coated with non-magnetic Ni-P alloy (0À75-2À5 Á) bears a magnetic layer of Co-P alloy overlaid with mixed cobalt oxides (e.g. 250-1250  thick) containing adsorbed silicone oil. The oxide layer may be produced by (1) coating the cleaned Co-P surface with a synthetic polymer e.g. polyamide and then heating at 260-290 C. for at least 8 hours; or (2) immersing the Co-P surface in 0À16-2À0 wt. per cent HNO 3  for 1-6 minutes, then heating at 230-260 C. for 0À5-4 hours. The magnetic layer itself may be formed by electrodeposition. The recording member may include superimposed magnetic layers, optionally separated by layers of non-magnetic nickel, and increasing in coercivity towards the substrate. The lubricant layer is applied by polishing.

Abstract: 1,267,264. Winches. HYDRAULIK BRATTVAAG A.S. 7 Jan., 1970 [11 Jan., 1969], No. 802/70. Heading B8B. An hydraulic winch system for slueing a loading boom of a ship's derrick comprises a pair of hydraulically driven guy wire winches 16A, 16B connected to a common source of pressure fluid, the winches having wires 20, 21 engaging the boom from opposite sides and being controlled by valve means whereby when one winch is hauling and the other is paying out, the flow of fluid through the paying out winch is restricted to maintain the wire therefrom taut. Hydraulic fluid from a line 26 is supplied to the winch motors 15A, 15B and returns to a control valve 25 through lines 24A, 24B depending on which winch is selected to pay out, the fluid passing between the motors through a line 29 connected to a discharge line 28, to which fluid returning to the valve 25 is discharged. A reduced winding pressure for both winch motors is obtained simultaneously by a neutral setting of the valve 25, in which the supply is open to discharge from the valve 25 through a throttle valve 27 which reduces the supply pressure. One way back pressure valves 30 in the lines 24A, 24B create a back pressure in the associated motor which is paying out wire whereby a braking action thereof is achieved to hold the wire taut. In a further embodiment, Fig. 3 (not shown), a valve is placed between the control valve and the rest of the circuit to facilitate the driven pay out of one winch whilst the other is held stationary. In a further embodiment, the speed of pay out of each winch motor is limited due to a by-pass valve which prevents the fluid discharging from the paying out winch motor to re-circulate through the motor to prevent the formation of a reduced pressure and hence speeding up of said winch.
