Title: Stuffers for printed sheet material
IPC: B65H43/00
Filed: 1975-05-28
Abstract: 1499197 Collating apparatus HARRIS CORP 28 May 1975 [3 June 1974] 23250/75 Heading B8R In a collating apparatus wherein sheets separated from the bottom of a plurality of stationary piles are deposited in a series of packets moved along a path beneath the piles, failure of a separator to deposit a sheet in a given pocket is sensed and an adjacent stand-by separator is caused to take a sheet from its associated pile and deposit it in the said pocket. General arrangement.-The piles are arranged in a series of bottom-feed hoppers 12 spaced around a closed-loop path beneath which the pockets 16 circulate. The loop operates in two independent sections 10A and 10B and completed piles (e.g. newspapers) are discharged on to output conveyers 13 and 15. Each of the sections is provided with an automatically filled hopper 12A, receiving freshly printed jackets from a press along conveyer 11A or 11B. Alongside and downstream of each automatically filled hopper is a standby hopper 12B. Separating sheets.-Each hopper includes a cam operated vacuum separator assembly 30 which transfers sheets to rotary gripper cylinders 20. A blade 28 is inserted between the sheet to be separated and the rest of the pile. Failure of the separator to operate correctly is sensed by the absence of a sheet under sensing arm 42 causing actuation of the standby separator. The standby separator is operated by supplying suction to its suction cups 25 or by releasing a latch mechanism which normally holds its suction assembly 30 in contact with the pile.

Title: Ion lasers
IPC: H01S3/03
Filed: 1972-05-19
Abstract: 1360129 Lasers WESTERN ELECTRIC CO Inc 19 May 1972 [20 May 1971 30 Sept 1971] 23583/72 Heading H1C An ion laser using a vaporizable material as an active medium is pumped by an electrical discharge which passes through an apertured body or bodies formed of or including the vaporizable material. The laser may for example have a discharge path defined by pure cadmium discs 14 A-D, Fig. 1, and insulators 15 A-E, these bodies all having a central bore. The heat of the discharge serves to evaporate the cadmium to give a uniform active medium. A visible or U.V. output may be obtained by choice of reflectors. The larger bore of the cadmium bodies allows for a gradual deposition of cadmium transported along the path by cataphoresis; a tapered bore may be used instead. A heater 24 helps to reduce such deposition. Helium or neon is added to the laser to enhance the excitation of the cadmium by collision transfer. Pure Cd<SP>114</SP> gives the highest gain, though natural cadmium may be used. Other active media are discussed in Specification 1,255,983. When a non-rigid material is used as the active medium, e.g. a liquid or powder such as mercury, selenium, sulphur or phosphoros, a perforated carrier body is used. Fig. 3 shows such a machined aluminium body where the perforation is a single slot 37. Cooling fins may be provided if necessary; if the temperature is to be raised the laser tube may be thermally insulated.

Abstract: 1314313 Measuring apparatus CARL ZEISS-STIFTUNG [trading as CARL ZEISS] 19 April 1971 [24 Fob 1970] 23720/71 Heading G4H In apparatus, for digitally measuring a dimension of an object, the focusing mechanism of a microscope 3 (Fig. 1) focusing an image of the object on to the cathode of a TV camera tube 4 is adjusted until the output signal from a control station 8 receiving at its input the video signal derived during a line scan is at a minimum. The vertical adjustment 7 of the microscope is then switched off and the measurement of the object is effected by counting the number of line scans for which the video signal exists. Area may also be measured by integrating the index signals. As described the control station 8 delivers to a differentiating circuit (Fig. 5, not shown) an amplitude significant signal representing the width of the video signal. After differentiation and amplification this signal is fed to a zero detector which, when triggered, operates a relay to prevent further movement of the microscope.

IPC: F16D3/205
Filed: 1949-09-15
Abstract: 679,965. Universal joints. MONO PUMPS, Ltd., and EDLIN, H. A. J. Sept. 4, 1950 [Sept. 15, 1949], No. 23849/49. Class 80 (ii). The invention relates to universal joints of the type comprising a ball member 15, which by virtue of opposed flats 15a on its surface, is received within a slot 12 in a socket member 10, the ball and socket members 15, 10 then being turned relatively to one another through 90 degrees in order to complete their engagement, at least one removable pad, block, pin stud or the like 23 lying within the slot 12 and engaging one flat face 15a to enable a rotary drive to be transmitted by the joint. According to the invention, the ball and socket members and the pad, enable the members to be relatively swivelled to an unusual extent while the members are coupled together, for attachment and removal of the pad from the ball member. In the construction shown in Fig. 3, each pad 23 has a shank 20 which can be entered in a central aperture 19 in the ball 15 when the latter is tilted to an abnormal degree (shown in dot- and-dash lines). In a modified construction, Fig. 4 (not shown), the shank 20 is in threaded engagement with the ball, and the slot 12 extends to, and breaks into, the outer surface of the socket member. In a further modification, Fig. 5 (not shown), each outer end of the'slot 12 is of spherical form to correspond with the curvature of the pad 22. The latter is thereby retained in position without the need for a shank 20, or aperture 19 in the ball member. In another alternative, a single pad located in the slot 12 is secured to the spherical surface socket member. The joint is applicable to pumps, particularly for circulating or delivering food materials, to linkages for aircraft and ship controls, to controls for I.C. engines, machine tools, motor vehicles, tractors and cranes, and to cable ends. Specifications 571,499 and 571,500 are referred to.

Title: Improvements in and relating to the manufacture of lead compounds
IPC: C01G21/00
Filed: 1925-09-29
Abstract: 249,809. Commonwealth White Lead & Paints Proprietary, Ltd. March 30, 1925, [Convention date]. Lead oxides; red lead; white lead; lead sulphate and other lead salts. - Lead compounds are produced by the action of suitable reagents upon briquettes of more or less oxidized lead powder, the spaces between the particles being occupied by air, water, reagents, or reaction products. The oxidized lead powder is produced from lead in a rotary drum 2 preferably divided with ribs 13. The lead may be fed in the molten state by a valved pipe 11 from a melting pot 9, and the drum is heated bv a furnace 6 having an oil-burner 7 so as to maintain the lead in fusion, but not hot enough to produce massicot. Air is drawn through the apparatus, entering at 8 and passing out at 16, carrying with it the oxidized lead powder. The outlet 16 adjoins a stationary casing 17 having a branch 20 leading to settling chambers 21, 23, and fan 24, and a lower branch leading to a settling chamber 18 having an opening 19 into which air is drawn so that only heavy particles are collected at 18 and are returned to the drum. The dust collected in the chambers 21, 23 passes into a casing 26 serving as a mixing chamber in which water is added through a pipe 33. The material is fed by a screw conveyer 31 and mixed with the water by beaters 30. The paste is delivered to a press and formed into briquettes, preferably of the shape shown in Fig. 4, no particle being more than about half an inch from a free surface. The briquettes may be aged by exposure, when they become partially carbonated. For making red lead, the aging is preferable; the briquettes are placed in a muffle 41, air being admitted at 42, an exhaust flue 43 being provided at the other end. The briquettes are placed on trays 44 with their perforations in line. The briquettes contain 80 per cent red lead after four hours at 490‹ C. or are wholly converted to yellow monoxide in two hours at a higher temperature. White lead is made by treating the briquettes (with or without aging) by the stack method, and lead sulphate is made by treating the aged briquettes with sulphuric acid.
