Title: Improvements in or relating to mechanical automatic-recording apparatus tensile testing of material
IPC: G01N3/06
Filed: 1964-08-04
Abstract: 1,063,336. Recording apparatus for tensile testing apparatus. RIKAGAKU KENKYUSHO and KAWASAKI SEITETSU KABUSHHIKI KAISHA. Aug. 4, 1964 [July 31, 1963; Sept.28, 1963(3)], No.31471/64. Headings G1J and G1S. In a device for testing the tensile stress of a specimen 1, there is provided means for detecting elongation and width contraction of a specimen 1, the movement of elongation marking means being amplified by means 2 and transmitted through a cord 4 to rotate drums 67 mounting recording paper, which move against a pen 16. The cord 4 is further wound round a drum 9 geared to a drum 8 to rotate it at the same speed as drum 7. Changes in width of the specimen are transmitted through a weighted cord 5 to move a pen 11 along recording paper mounted on drum 8. The specimen 1 is clamped by two spring-loaded clamps 28 against knife edges 29 supported respectively by a casing 26 and a spring-loaded ram 27 mounted on member 33. Pulleys 36-40 are mounted between the casing 26 and member 33 so that as the specimen elongates under stress, relative movement between the parts 26, 33 is magnified by the pulley system and relayed to the string 4 subsequently causing rotation of recording drums 6, 8. Amicrometer 34 is provided to check the spacing of the knife edges 29. The width contraction device comprises contact pieces 49, 49' and biased towards each other to grip the specimen by a spring 53, and a weight 12 attached to a string 5 wound around a drum 45 mounted on a screw-rod 43 extending between the two parts 46, 51. Hence in use, contraction of the specimen caused elongation of the string 5 which is attached to the recording pen 12. A load transmitting rod 13 moved through means 18, 23, 24 by the pendulum 25 of the testing machine supports a pen 16 movable across the recording drum 6 the pen 16 being balanced by a weighted pulley system 14, 14', 15, 17. The ratio of the indicated load to the actual load may be adjusted, see Fig. 5, by altering the position of contact of roller 23 on the spring biased lever 24 by operation of screw 58 of a vernier gauge 60. A logarithmic scale may be recorded on the recording paper.

Title: Apparatus for loading blank record discs into a container
Inventor: PHILLIPSON ALAN
IPC: B29C43/02
Filed: 1964-02-06
Abstract: 1,071,338. Packaging-machines; endless conveyers. DECCA Ltd. July 9, 1965 [Aug. 4, 1964], No. 31591/64. Headings B8A and B8C. An apparatus for packaging blank recording discs in a storage cylinder as they leave a moulding machine, comprises means to feed each disc in turn to lie coaxially with and at an open end of the cylinder and two rams, one extending internally the length of the cylinder to support the stack of discs as it builds up, and the other reciprocating to feed the discs into the cylinder against the pressure of the first ram. The discs roll from the moulding machine down a shoot 11, their descent being controlled by photo-electric means 12 and stops 13, into pockets in an endless conveyer 19. The pockets are each formed by a bar 32, grooved to receive a disc and U-shaped rods to hold the disc upright. The conveyer is moved in pocket width steps to give the discs time to cool, by a reciprocating block 38, Fig. 3 (not shown), carrying a pawl which engages a pin 24 protruding horizontally from one end of each bar 32. At a position adjacent a guide 56, a pusher 55 thrusts the disc along the guide and in front of a ram 63 which then presses it into the cylinder 71 against the second ram 75. The latter protrudes through an aperture in the cylinder base and is telescopic. An arm 93 carrying a feeler is pivoted, during filling, against the cylinder end, so that the feeler enters the base aperture and is contacted by the rear face of the head of the ram 75 when the cylinder is nearly filled, to commence operation of counting means. This stops the infeed when the cylinder is full. The feed is also controlled by microswitches contacted by the disc as it enters and leaves the conveyer and comes to rest in front of the ram 63. The entire ram 75 is mounted on a sliding carriage to permit its withdrawal from the cylinder to enable the latter to be removed.

Title: Improvements in absorptiometers and like apparatus
Inventor: STOTT FRANK DUDLEY
IPC: G01N21/25
Filed: 1955-11-04
Abstract: 840,848. Photo-electric absorptiometers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 25, 1956 [Nov. 4, 1955], No. 31670/55. Class 40(3). In an absorptiometer a solution to be evaluated in an open-mouthed vessel 5 is compared photoelectrically against a known solution in a similar vessel 6. Beams of light from a source in box 23 are reflected and focussed by lenses and prisms mounted on part annular retainers 40 on the top of plate 17, on to the glass bottoms of the vessels 5, 6 where they are diffused by screens 47 on to barrier layer photo-cells 51, 52 which revolve around a shaft 49. The cells are connected in series and the current is fed through a commutator 55, 56 to a centre zero microammeter (not shown). In use, the plate 17 is rolled back by a lever 19 and equal quantities of a known liquid are introduced into both vessels. The motor 48 is started to revolve the photo-cells and one of the beams is adjusted by an iris diaphragm 44 to provide an initial zero reading on the meter. The unknown substance is then introduced into the vessel 5 whilst a standard solution is gradually added to vessel 6 by a titration burette 66 which swings on a sleeve 62 into a recess 29a in the prism. (An optically balancing recess 28a is provided on the other prism.) When sufficient solution has been added to restore equality of light absorption the meter will give a null reading. The bottom of the vessels are shaped to the meniscus of the liquid and the vessels are elongated cylinders so that the depth of the solution is proportional to the volume. The vessels are mounted in revolvable bushes 8 biased to the vertical by springs 14. Cords 11 wound round the bushes and passed outside the casing are used to agitate the vessels. A coloured filter 27 may be interposed to give light of selected wave lengths. The meter and photo-cell assembly is removable and the microammeter may control the burette automatically.

Title: Improvements in or relating to velocity modulation electron discharge apparatus
IPC: H01J25/78
Filed: 1958-10-06
Abstract: 844,730. Velocity-modulated tubes. WESTERN ELECTRIC CO. Inc. Oct. 6, 1958 [Oct. 21, 1957], No. 31801/58. Class 39(1). The efficiency of operation of a velocity-modulated tube is increased by collecting the electron stream at a point where the velocity spread is a minimum. In the travelling- wave tube of Fig. 1, the collecting system, positioned after a drift space, defined by a sleeve 21 or by the inner periphery of the envelope, in which the beam is characterised by regions of high and low electron velocity spread, comprises a focusing electrode 22, a decelerating electrode 23 and a cup-shaped collector electrode 26. Electrode 22 is at the point where the velocity spread is a minimum, and a space charge region is established between electrodes 22 and 23. The electrodes 22 and 23 are so shaped that the equipotential lines are normal to the decelerating packs of electron flow, whether the collecting system is designed for parallel or diverging flow before collection. Electrode 23 includes a curved grid 27 to define an equipotential surface and is so spaced from the electrode 22 that the D.C. velocity of the electrons is reduced to zero while the A.C. velocity of the electrons remains constant. The cup-shaped member 26 and grid 27 may be replaced by a solid graphite block 30, Fig. 4. The axial distance d for the collecting system is measured between an arc 45 extending across the outer periphery of the aperture of the focusing electrode 33 and the equipotential surface 46 at which the beam is completely collected. An equation is given for calculating d. Electrode 35 is the decelerating electrode. In another modification block 30 consists of tungsten with its outer surface composed of a plurality of porous regions made, e.g. by pressing a mixture of copper and tungsten powder into the required shape and then heating the block to evaporate the copper so as to leave porous regions on the surface. In other modifications, electrodes 30 and 35 are combined into a single electrode and the target area comprises a plurality of circular or triangular grooves, or a honeycomb grid. All these arrangements are designed to inhibit secondary emission. The invention is also applicable to backward wave oscillators and klystrons. The theory of the arrangement is given.

Abstract: 379,564. Book-stitching machines. SINGER MANUFACTURING CO., Elizabeth, New Jersey, U.S.A. Nov. 17, 1931, No. 31826. Convention date, Aug. 22. . [Class 112.] The needle of a book-stitching machine passes through a hole previously formed by an awl, while the awl drills the next hole. The awl 28 is carried by a shaft 29 which is rotated. by a double belt 51 driven from an independent motor 42. The shaft 29 is connected by an arm 39 to the needlebar 15 so that the awl and needle reciprocate together. The work is fed by a four-motion feed-dog and a feeding-foot 73, which reciprocates alternately with apresser-foot 64 to keep the work clamped. The reciprocating mechanism comprises an eccentric 86, a lever 82, and a bellcrank lever 78, 79, the pivot 80 of which slides in the slot 71 of a bracket 70 on the presser-bar 63. The awl comprises a shank 57 and a cylindrical blade 58 having a single side flute 59 cf V form. It is guided by a hole in the presserfoot 64 and is lubricated by a pad projecting from an oil-cup 89 which is carried by a lever 88. Each time the awl is raised a pin 94 engages a cam surface 92 on the lever and the pad is brought into contact with the awl. Paper chips are blown away by a wind nozzle 56.

Abstract: 657,524. Hygrometers. AKTIEBOLAGET SVENSKA FLAKTFABRIKEN. Dec. 9, 1948, No. 31894. Convention date, Dec. 11, 1947. [Class 97 (iii)] Apparatus for comparing the moisture contents of two gases comprises two pipes 1, 2 through which the gases flow, a heat-exchanger 11, 12 for bringing the two gases to the same " dry-bulb " temperature and two wetbulb " thermometers 15, 16 are in each pipe, the " wet - bulb " thermometers being connected to a common differential device 19 which may be used for indicating, measuring or control purposes. Preferably the gases are drawn through the pipes 1, 2 by a common suction pump 8. To prevent condensation the gases may be heated by heaters 9, 10 before passing into the heat-exchanger. The heat-exchanger may be formed by close winding the two pipes around a former so that their coils lie adjacent to each other and the exchanger may be surrounded by a common heating element in place of the separate heaters 9, 10. Alternatively the common heater and heat exchanger may comprise an inner cylindrical sleeve containing the heating element, around the outer periphery of which is helically wound two edgewise sheet-metal strips, the whole being contained in an outer sleeve so that the edges of the strip are in close contact with both sleeves, thus forming two separate but adjacent spiral paths for the gases.

Title: Improvements in or relating to methods and apparatus for attaching armature conductors to commutator segments in dynamo-electric machines
IPC: H01R39/32
Filed: 1948-12-09
Abstract: 657,572. Control systems for resistance heating. GENERAL ELECTRIC CO., Ltd., and SHALLCROSS, H. Dec. 9, 1948, No. 31911. [Class 38 (iv)] [Also in Groups XI and XXII] An electricity supply system for a machine for soldering armature conductors to commutator segments (see Group XXII) supplies an interrupted alternating current to soldering electrodes 31, 30 (see Group XI), an interrupted direct-current to a solenoid or rotator 57 adapted to rotate the armature 10, and a directcurrent to a solenoid 35 adapted to apply the electrode 31 to the field conductors. A heating tower 50 includes three similar circuits which serve to control adjustably the overall time for each soldering operation on a group of conductors, the duration of each pulse and the interval between the pulses of the alternating- current supplied from supply 53 through a contactor 52 and a transformer 54 to the electrodes 30, 31. The circuits, which may be fed from a direct-current supply 55, comprise a condenser charged through a resistance and connected to a gas-filled discharge-tube which causes a relay to operate when the charge on the condenser reaches a predetermined value. The value of the condenser or the charging resistance is adjustable either in steps or continuously to adjust the delay of the timing circuit. The first circuit, which controls the overall time for each operation, also operates the solenoid 35 and is closed at the same time as the second circuit controlling the duration of each pulse. When the second circuit is closed, the third circuit for controlling the interval between the pulses is opened, and when this circuit closes the second circuit again opens. This is repeated until the first circuit opens at the end of said overall time. The pulses of direct-current transmitted to the rotator 57 from a rotation-control tower 51 are produced by a circuit including a gas-filled relay tube, the number of pulses being controlled by a similar circuit. A foot-control 56 connected direct to the solenoid 35, rotator 57 and contactor 52 may be used instead of the automatically-controlled heating tower 50 and rotation control tower 51. Specification 549,503 is referred to.

Title: Improvements in or relating to telegraphic exchange systems
IPC: H04L25/20
Filed: 1930-10-23
Abstract: 365,642. Telegraph exchange systems. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. Oct. 23, 1930, No. 31922. Convention date, Oct. 24, 1929. [Class 40 (iii).] The system described is identical with that of Specification 361,546. The claims relate to the provision of a condenser 10 with, if necessary, a resistance in series, to prevent the operation of the relay SR during the transmission of a message to the subscriber Tn by the relay ER. When the contact er is moved to its working position the contact of relay SR is maintained by a circuit through the winding II including a resistance 6, equal to that of the lines 3, 4 and the receiving magnet EM. The contact er on return to its normal or rest position closes the original closed circuit through the lines 3, 4, but on account of the self-inductance time lag during which the current in the winding II of the relay SR will rise to its steady value the current in winding I will tend to operate the relay. To compensate for this, the charging current for the condenser 10 and the time constant of the condenser circuit are adjusted to provide an approximately constant current in winding II and to be nearly equal to that of the original closed circuit through the lines 3, 4. In Fig. 2, a condenser 10<1> is similarly included at the exchange VM<1> to prevent the operation of the relay SR<1> by the operation of the contact er<1> during transmission to the exchange VM.

Abstract: 341,870. Valve circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13A, Emmasingel, Eindhoven, Holland. Oct. 21, 1929, No. 31933. Convention date, Oct. 29, 1928. [Class 40 (v).] In a receiver having one or more high-frequency valves fed from a common filament supply, coupling between valves in which high-frequency currents occur is avoided by using reactances, such as a condenser 7 and high-frequency choke 8, connected respectively in parallel and in series with the filament leads between the valves. The choke 8 is connected in the filament lead not connected to the negative side of the anode battery 9. The Specification as open to inspection under Sect. 91 (3) (a) refers to the avoidance of coupling between valves with indirectly heated cathodes by connecting a condenser between the centre of a potentiometer connected across the filament and one or both of the filament leads. This subjectmatter does not appear in the Specification as accepted.
