Title: Method of sorting objects
Inventor: CASS WILFRED RICHARD
IPC: G01N21/88
Filed: 1965-07-16
Abstract: 1,091,958. Photo-electric flow detection. GUNSON'S SORTEX Ltd. July 15, 1966 [July 16, 1965], No. 30393/65. Heading G1A. To sort imperfect objects having flaws in their otherwise impermeable surfaces from perfect ones, liquid penetrant is applied to all objects and is retained in the flaws upon its subsequent removal from the unflawed parts of the objects' surface: a photo-electric device by being responsive to light having a characteristic particular to that reflected by the penetrant then detects the flawed objects as it views each one in turn. The penetrant may be coloured with a fluorescent dye and be viewed under ultraviolet light, or the penetrant may have a colour readily distinguishable from the surface colour of the objects. The objects, which may be ball-bearings, are fed on to the upper run (2) of a conveyer by a loading device (3) comprising a pair of discs (4, 5) having peripheral holes. The bearings are de-greased by sprays (8) and the penetrant is supplied by sprays (6, 7) above and below the conveyer surface penetrant is washed off by sprays (9, 10). The bearings are dried by a heater (12) and talc or silica powder is directed on to them by sprays (15, 16) to absorb or adsorb penetrant from a flaw. Surplus powder is removed by compressed air through devices (17, 18) and the bearings drop from the end of the conveyer on to one of two slat conveyers (27, 28) in baths (25, 26) by passing through a photoelectric examining device (19), comprising an ultraviolet source and a pair of photo-cells (21, 22) which are connected to control a pneumatic separating device (24) directing the bearings into the appropriate bath. At least one of the photocells is responsive to the fluorescent light.

Title: Improvements in or relating to ultrasonic inspection apparatus
Inventor: HANSTOCK RAYMOND FORD
IPC: G01N29/265
Filed: 1959-09-09
Abstract: 883,173. Ultrasonic inspection devices. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 25, 1960 [Sept. 9, 1959], No. 30786/59. Class 40(7). In ultrasonic inspection of a weld 2 between the dome 4 of a cylindrical pressure vessel and a stand pipe 3, a non-rotatable probe 5 and a rotatable reflector 7 provide a sequence of peripheral scans of the weld. Damage to the cable feeding the probe, and scanning of non-welded zones, are thus avoided. In one embodiment pinion 57 rotation by wheel 61 or, via clutch 64, electric motor 63 turns bevel wheels 20, 32. Wheel 20 rotation causes tube 16 and by pin 68, tube 12 and reflector 7 to rotate. Any tendency of tube 6 to rotate also, due to friction of ball bearings 14, 15 between tubes 6, 12 is prevented by pillar 56 restraining fork 55 attached to head 51 on the upper end of tube 6. Wheel 32 rotation causes yoke pin 37 to impart a vertical oscillatory motion to yoke 38 and connecting rod 42, and hence also to screwed ring 47; the oscillatory motion is transmitted to tube 12, and tube 6, so that tube 12 and reflector 7 are moved, in the course of each revolution, through a cycle of upward and downward displacement so as to follow the inclination of the weld joint. A spiral upward feed motion is superimposed by ring 47. The eccentric throw of pin 37 is adjusted so as to be the same angle as the plane in which the weld joint is orientated, and this adjustment is effected by loosening pinch bolts 71 on fork 46 so as to free ring 47, moving yoke 38 vertically until the centre of yoke pin 37 is the required distance from the centre of wheel 32, rotating ring 47 so that it moves axially along screw-threaded portion 48 of tube 12 until again aligned with fork 46, and retightening bolts 71. Drum 50 may carry a recording chart and echo signals may be displayed on a cathode-ray oscilloscope. Pipe 3 is filled with a liquid couplant, e.g. water. In another embodiment legs engaging the dome 4 support a plate thus aligned with the inclination of the weld joint and a vertical follower lifts an arm projecting laterally from ring 47, Figs. 2A, 2B (neither shown). Vertical movement of tube 12 may be effected by a cam engaging with the underside of a collar attached to the upper end of the tube.

Title: An improved process for the conversion of mineral oils into oils of lower boiling point
IPC: B01J21/04
Filed: 1934-11-24
Abstract: Hydrocarbon oils are converted into products of lower boiling point by treating them at temperatures from 150--300 DEG  C., in presence of a catalyst made by impregnating a carrier such as bauxite with a solution of the crystalline chlorides of zinc, aluminium or magnesium and evaporating the soaked carrier to dryness.  The bauxite is preferably prepared as described in Specification 445,727.  The catalyst is regenerated by boiling with water to remove the contaminating oil and calcining the wet residue at red heat.  The solution removed is then concentrated and poured onto the catalyst with fresh hydrochloric acid and aluminium chloride solution to make up for losses.

Title: Calculating mechanism in petrol pumps
IPC: B67D7/74
Filed: 1952-12-04
Abstract: 750,226. Counting-apparatus. KIENZLE APPARATE GES. Dec. 4, 1952 [Dec. 21, 1951], No. 30846/52. Class 106 (1). Counting apparatus, for petrol pumps arranged for the delivery of different fluids, registers the total cost and quantity of different fluids delivered simultaneously and the cost and quantity of one fluid if this is delivered alone. In an arrangement for dealing with two fluids, the input shafts 4, 5 operated by the pumps drive through change-speed gears 2, 3, respectively adjusted according to the prices per unit quantity of the fluids, cost counters 10, 13 and shafts 27, 28 respectively geared to sun wheels 36, 36a of a differential gear. The sun wheels are conneoted by pairs of pinions 37, 39 and 38, 40 mounted in a rotatable housing comprising gear-wheels 45, 46 which drive a counter 50 visible through windows 20 to register the total cost and a grand total counter 53 behind a window 24. The counter 50 is re-set prior to the operation. A similar differential gear driven directly by the shafts 4, 5 operates similar counters visible through windows 16, 25 to register the total quantity and the corresponding grand total. The use in the differential gear of intermeshing planet pinions ensures that back-lash in the gearing between the pumps and the sun wheels 36, 36a is taken up. Thus, if only one fluid is delivered, it is not necessary to lock the non-operated sun-wheel.
