Title: Device for setting rivets in a wall which is accessible on one side only
IPC: B21J15/26
Filed: 1962-06-04
Abstract: 949,708. Blind riveting. SOC. GOBINDAUDE. June 4, 1962 [June 13, 1961], No. 21408/62. Heading B3U. A blind riveting gun comprises a tubular body terminating in a nose adapted to receive the mandrel of a rivet and mandrel assembly, mandrel clamping means axially movable inside the body, and a head coupled to the body and to the mandrel clamping means by coupling means designed to produce a tractive effort on the clamping means when the head of the device is rotated relative to the body. The tubular body 6 has a screwed-in nose 7 and accommodates a tube 8 which slides axially but is prevented from rotating by a key 11, which is mounted in a member 12 screwed into the tube 8, and which runs in a slot 13 in the wall of the body 6. The assembly of the member 12 and the tube 8 is biased toward the nose 7 by a spring 15. At its forward end the tube 8 is frusto-conical in shape and contains a pair of jaws 18, 18a, which are biased to the forward position by a spring 21. In this position the jaws are separated by the intrusion of the conical end of the nose 7. Secured in the member 12 is a screw 23 which is engaged by a splitnut 25. The forward end of the nut is conical and seats in a recess in a washer 26 which rests on a thrust-bearing 27. The thrust bearing is supported by a cap 16 screwed into the tubular body 6 and is retained by a cap 28. The halves of the nut 25 are mounted in a cylindrical part for rotation therewith, but can pivot about pins 34a and 34b and are biased by a spring 36 to open out to a position in which they are disengaged from the screw 23. The cylindrical part has a stem 33 adapted to engage a rotary machine such as a portable drill. Operation.-The mandrel of a rivet assembly is inserted in the nose 7 and applied by means of the body 6 to the parts to be joined, the member 32 is rotated and draws back the screw 23 so that the jaws 18, 18a grip the mandrel and draw it into the rivet until the mandrel breaks off at a weakening groove. Under the elasticity of the screw-and-nut assembly the latter separates from the washer 26, the half-nuts part and the components 23, 12 and 8 revert to their original positions.

Title: Improvements in the employment of cathode ray oscillographs
IPC: G01R13/24
Filed: 1923-08-24
Abstract: 221,338. Western Electric Co., Ltd., and Kipping, N. Aug. 24, 1923. Electrostatic meters.-In order that a cathoderay oscillograph shall indicate an alternating wave form in a sinusoidal form, the cathode ray is deflected in one direction in accordance with current or voltage variations obtained from one source, and in a direction at right-angles to this in accordance with variations in the current or voltage from another source to be examined. The cathode-ray oscillograph 7, Fig. 2, has a filament 8, a screen 9, an anode 10, and pairs of deflecting plates 11, 12. One pair of plates 12 is connected across a portion of a resistance 16 connected to the source 15 to be examined. The other pair 11 is connected across a portion of a resistance 6 in a circuit comprising a battery 1, a voltage regulator 2, and a neon or like lamp 3 shunted bv coarse and fine adjustable condensers 4, 5. The potential difference across the lamp 3 gradually build's up to the critical striking value and then falls below this value so that the lamp alternately strikes and fails giving a potential curve as shown in Fig. 3, which is composed of approximately straight lines. The frequency of this potential is adjusted bv varying the condensers 4, 5 until an integral multiple thereof is equal to that of the source 15 under examination, thus giving a reflection of the ray proportional to time. By causing the neon lamp oscillator to make two complete vibrations while the generator supply makes an odd number of cycles, superposed curves as shown in Fig. 6 are produced enabling the upper and lower halves of the wave to be compared. Voltage surges may be observed and measured by transparent square'd paper held over the screen of the tube.

Title: Improvements in or relating to fuel distributors
IPC: F02M69/14
Filed: 1955-07-25
Abstract: 817,722. Distributing valves; regulating. SCHMIDT, F. A. F. July 25, 1955 [July 27, 1954], No. 21515/55. Class 7(6) [Also in Group XXVI] In a fuel distributer comprising a pair of rotating discs 6, 7, with overlapping slots 11 which periodically connect orifices 4 in a plate 5 with passages 8 leading to the injection nozzles, the, discs 6, 7, are angularly adjustable relative to one another in accordance with the speed thereof and one disc 7 has one or more additional orifices 12, Fig. 3b immediately following the slot 11. The disc 6 is rotated by an engine-driven shaft 9 integral with a flange 18 which drives the disc 7 through a centrifugal governor consisting of springs 18, Fig. 2, weighted by weights 10 and connected to pins 16, 17, on the flange 18 and disc 7. As engine speed increases the weights 10 fly outwards and, through the springs 19, cause adjustment of the disc 7 relative to the disc 6 to increase the amount by which the slots 11 overlap, thereby compensating for the reduction in delivery due to the increased speed. The disc 5 is adjusted in accordance with load by a shaft 14 to move the orifices 4 therein out of alignment with the passages 8 to reduce the delivery at reduced loads. To avoid an excessive reduction in delivery as the orifices 4, 8, are moved out of alignment at partial loads, Fig. 3a, the orifices 12 increase the period during which the orifices 4, 8, are in communication. An additional orifice 13, Fig. 3b, which is permanently in communication with the fuel supply space 3, is provided for the supply of idling fuel. In a modification, Fig. 5, the plate 5 is fixed and the fuel pressure in the supply chamber 3 is arranged to increase in accordance with load by a by-pass valve 27 the spring load of which is controlled in accordance with load by a rod 24. Alternatively a constantly loaded by-pass valve is combined with a throttling needle adjusted according to load. Specification 817,721 is referred to.
Patent GB-629915-A (GB)
Title: Improved oxo synthesis process
IPC: C07C45/50
Filed: 1947-08-07
Abstract: In the reaction of olefins, carbon monoxide, and hydrogen in the presence of iron, cobalt, or nickel to give oxygenated products such as aldehydes and ketones, followed by hydrogenation to the corresponding alcohols, the products from the synthesis zone are removed, purged with hydrogen, and the hydrogen separated, before the products are passed to the hydrogenation zone.  The purging removes carbon monoxide and may be effected at the synthesis or hydrogenation temperature or pressure.  Reduced pressures, e.g. 100-500 p.s.i. are more effective while the use of the hydrogenation temperature decomposes cobalt carbonyl in the synthesis product.  Synthesis is generally effected at about 150-350 DEG  F. and 1000-6000 p.s.i. and hydrogenation at about 200-500 DEG  F. and 500-5000 p.s.i.  The hydrogenation catalyst may be the cobalt catalyst used in the synthesis or, for example, nickel, tungsten or metal sulphides. Olefines of 2-18, especially 8-18, C atoms are preferred, and include mono- and di-olefins, olefin polymers, and olefinic hydrocarbon fractions. Ratios of H2 : CO may be 0.5-4 : 1.  The reactants may be passed upwards through the synthetic catalyst, the products passed to a gas separation zone, the gases recycled, and liquids fed to a purging zone packed with porous material in countercurrent to a stream of hydrogen which is then recycled to the synthesis zone. In an example, di-isobutylene is the olefin, and cobalt-thoria-kieselguhr is used at 250 DEG  F. and 3000 p.s.i.  The pressure is reduced to 200 p.s.i. while purging.

Patent GB-1041516-A (GB)
Title: Process and apparatus for forming aggregates of powdered materials
IPC: C09C1/58
Filed: 1964-05-26
Abstract: Powdered material is pelleted by subjecting a contained wetted mass of the powder to agitation with mechanical members to aggregate the wetted particles during movement of the members through the wetted mass, the physical characteristics of the resulting pellets being controlled by regulating the amount of work expanded in agitating the mass. The regulation of work, which is proportional to variations detected in the work level required for moving the members through the mass, is effected during the agitation by varying the resistance afforded by the mass to the movement of the members.  This resistance is directly proportional to the volume of the mass, which is controlled by the discharge rate of the resulting pellets from the agitation zone.  The regulation of work, which preferably is such as to maintain a work input level that is critical for the optimum formation of pellets having specific physical characteristics, preferably is effected in response to actuating signals proportional to variations in the work level, the actuating signals preferably being generated automatically in response to the variations which preferably are determined automatically.  Apparatus for the pelleting process comprises a mechanical agitator adapted to contain a wetted mass of powdered material and including mechanical members which move through the mass and cause the particles to aggregate, detector means for determining variations in the work level required for moving the members within the mass, and regulating means for varying the resistance afforded by the mass to the movement of the members by varying the volume of the mass which is determined by the rate of discharge of the pellets from the agitator, the variation in resistance being proportional to variations detected in the work level and being effected during the agitation of the mass with the members. Preferably, there are also means, for example a controller device, for transmitting actuating signals to the regulating means, the signals being proportional to variations in the work level and being automatically furnished in response to signals generated by the detector means.  The agitator may comprise an elongated conduit through which the wetted mass advances in an axial direction, the members moving transversely through the mass as it advances.  The conduit is preferably constructed to allow spiralling of the advancing mass, which conforms generally to the periphery of the conduit. The regulating means may comprise a flow regulator for varying the discharge rate of the mass from the conduit.  The wetted powder mass may be carbon black wetted with an aqueous liquid, there being up to 2, preferably from 0.5 to 1, parts liquid per part black, by weight.
