Abstract: 1,228,163. Planing; beds and frames. G.K.N. GROUP SERVICES Ltd. 29 May, 1968 [3 March, 1967], No. 10050/67. Headings B3B and B3L. A planing machine for planing defects from billets before further processing comprises a tool holder 46 movable vertically along a first line, billet gripping and moving means to grip and move a billet horizontally along a second line intersecting said first line, fluid pressure operable means 41 to move the tool holder 46 along the first line towards the second line and thus to urge a tool 51 into engagement with the billet. The fluid pressure operable means 41 includes control means, e.g. a blow-off valve, for maintaining the fluid pressure at a predetermined value so that the position of said tool holder 46 along the first line is determined solely by the balance of the force exerted on the tool holder and the component along said first line of the reaction between the tool and billet. A constant cut irrespective of the longitudinal profile of the billet is thereby obtained. A range of pre-set blow-off valves may be provided each one connectable to the supply circuit to enable a required depth of cut to be selected. The planing machine comprises a set of resiliently mounted rollers 28 co-operable with a retractable driven roller 22 to position a defect adjacent the tool 51; hydraulically operated transverse and vertical slides 39, 47 for the tool holder 46; a billet clamping vice 59, 60 mounted for longitudinal movement by an hydraulic jack 65 for advancing a billet in steps past the tool 51; and fixed billet clamping means 71, 72 for gripping the billet when the vice 59, 60 has been unclamped and is moving back to the start of its stroke before re-clamping the billet and advancing it another step. The machine is controlled by an hydraulic circuit (Fig. 2, not shown) including restrictions to slow down the speed of movement of the various hydraulic jacks. A number of sequences of operation of the movable vice 59, 60, clamp means 71, 72, and rollers 22, 28 for feeding the billet are referred to. In modifications the frame of the machine may be C-shaped to enable full visibility from one side; the tool holder 46 may carry an indexing head having a number of tools therein; facility for automatically retracting the tool at the end of every second cutting stroke; and the machine may include an automatic defect detector such as an eddy current detector or ultrasonic detector.

Abstract: 1,230,529. Rotary shaft seals. CRANE PACKING CO. 5 June, 1969 [5 June, 1968], No. 28623/69. Heading F2B. In a rotary mechanical seal comprising relatively rotatable sealing members 10, 13 having radially disposed sealing faces 12, 14 which when the equipment being sealed is inoperative contact one another and under normal operating conditions, are separated by a gap which is wider at the high-pressure side of the seal than at the low-pressure side, means, e.g. vanes 22, are provided to force the sealed fluid between and thus separate the sealing members 10, 13 under start-up conditions. In the embodiment shown in Figs. 1 and 2, a rotor 10 is mounted on a rotary shaft 11 and a washer 13 is axially slidable mounted in the shaft housing 17 and sealed thereto by an 0-ring 19 and under normal operation the sealing faces 12, 14 are separated by a gap determined by the pressure of the sealed fluid in chamber 18. Spiral grooves 22 formed in the surface 14 are handed to cause fluid in chamber 18 to be forced radially inwardly when the shaft 11 rotates in the normal direction. When there is no pressure in chamber 18 the washer 13 is pressed against the rotor 10 by a light spring 20 and under start-up conditions the surfaces 12 and 14 are separated, to avoid rubbing contact, by the action of grooves 22. In a modification, Fig. 3, suitable for both directions of rotation of the shaft 11, a further axially movable washer 13<SP>1</SP> is slidably sealed in a rotor 26 on the shaft 11 and a ring 28 having seal-faces 30 and 31 is rotatably supported in bearings 29 in the housing 17 and disposed between the washers 13 and 13<SP>1</SP>. In one direction of rotation of shaft 11, washer 13<SP>1</SP> frictionally engages and rotates ring 28, a sealing gap being formed between faces 14 and 30 and, in the opposite direction of rotation of shaft 11, washer 13 engages and frictionally holds ring 28 against rotation, a sealing gap then being formed between faces 14<SP>1</SP> and 31.

Abstract: 1,231,704. Sorting potatoes photo-electrically. WEIMAR KOMBINAT VEB. March 10, 1969, No.12469/69. Heading G1A. Potatoes are sorted by conveying them from a feed conveyer 8 on the suction arms 1 of a wheel 2 to a photo-electric measurement zone 9 where internal and surface defects are detected by absorption of light passing through the potatoes from a source 5 mounted within the wheel, and then to a sorting station 12 where potatoes are separated in accordance with the measurement carried out at 9. The measuring zone can take a number of forms. It can comprise simply a number of detectors arranged around the position each potato takes up at the measuring zone, Fig. 2 (not shown). After natively, Fig. 3, each suction arm has mounted at its end part 13 of an ulbricht sphere, surrounding the potato. At the measuring zone is located the other part 14 of the sphere, fitted with shaded detectors 10 which can thus measure the integrated transmitted light. In a further alternative Fig. 4 (not shown) a group of spaced detectors is used and the suction arm is mounted for rotation in ball bearings by a friction wheel drive. The light source 5 is fitted with a reflector and has a filter 6 to select the wavelength of light used and collimating lenses 7. A sliding shutter 3 associated with each suction arm is controlled by control device 4 on evaluation of the detector output by circuit 11 so as to cause the required sorting operation at station 12.

A pipe 1 for internally supporting a pipe 7 includes .two segments 2, 4 whose edges 5, 6 are shaped with female and male co-operating surfaces respectively. Insertion of segment 4 into segment 2 expands the diameter of the pipe 1 so that by placing the segment 2 within the pipe 7 and then axially sliding into position the segment 4 prevents undue stress being placed -upon the pipe 7 during assembly. One or both segments 2, 4 may be made of plastics or metal.
