Title: Improvements relating to machines for assembling driving chains
IPC: B21L9/06
Filed: 1929-06-24
Abstract: 331,093. Renold, Ltd., H., and Renshaw, A. June 24, 1929. Chains.-The links and studs of transmission - chains are assembled on a table 10 rotated step by step, the table having notches 14 to receive pairs of studs at station A on which are placed links at stations B, C and D. At station A, Fig. 4, two shoots 44 feed pairs of studs to a slide 46 reciprocating as described in Specification 326,604, [Class 60, Grinding or abrading &c.], which by spring and cam action pushes them to register above two notches 14 in the table into which they are pressed by pins 66 of punch 64. A bottom plate and a shroud 34 keeps the studs from falling out. At station B pairs of centre links 16 fed from magazine 68 are moved by slide 70 to register over the studs where they are guided by spring pressed pins 78 and pressed over the chain studs by punch 76. At station C made-up links 18 are constantly supplied from a hopper as described in Specification 295,439 and at station D outer links are added, the chain then being half completed. It is then turned upside down and put through a similar machine but with a sprocket wheel instead of a table 10 and with supply and assembly stations C and D only. To divide the chain up into required lengths the feed of the components at certain points is interrupted by a pattern chain as described in Specification 295,439, a cam plate on this chain raising a lever 120 to foul part 123 on the feed slide and so hold it out against the pull of the springs and prevent it from feeding studs during that stroke. The absence of studs is used to stop automatically the feed of the links at station B, as spring pressed feeler pins 126 on the punch can then descend further so that their large ends press the tip of lever 124 and tilt it to foul part 70 of slide and so hold slide 70 out during that stroke to prevent feed. A similar arrangement is provided at station D. Station C however keeps on supplying the combination link unless the slide is locked by the attendant. In starting a chain, the links so supplied are returned by hand to the hopper. Magazines 68 and that at station D are filled by hand from pairs of wires on which the links are strung. An attachment for stringing the links or the wires comprises a hopper, shoot and stacker actuated by a face cam described in Specification 295,439. A thinner chain is made by pushing an inner combination over the pairs of studs at station B, Figs. 3 and 10, the chain then being received by a sprocket B with teeth 22, and backed by a slope 24 which pushes up the studs further through the link so that they can receive an outer top link at C. A bottom link is pushed up through a gap in the backing at D, a top pressure block 30 receiving the thrust. The step by step motionin both cases is obtained from a cam-operated reciprocated rod with clutch which grips in one direction only. The assembly may also be carried out by a flexible conveyer system instead of rotary tables.

Title: Improvements in television-receiving circuit arrangements
IPC: H04N5/57
Filed: 1959-06-12
Abstract: 919,128. Television. PHILIPS ELEC TRICAL INDUSTRIES Ltd. June 12, 1959 [June 14, 1958], No. 20211/59. Class 40 (3) In a television receiver, Fig. 1, variation in background brightness of the reproduced image due to variation in the working point of the video amplifier 4 (to which the cathode of the C.R. tube 7 is directly coupled) consequent upon variation of the screen voltage to adjust image contrast, is compensated by means of a variable-resistor arrangement which supplies two oppositely varying voltages U and V, the first to control the contrast and the second for application to the grid of the C.R. tube to compensate for the shift in cathode voltage. In Fig. 1 the network comprises two ganged potentiometers 8, 12 and ancillary resistors 9, 10, 13, 14. A desired relationship between background brightness and contrast may be obtained by: (1) relative adjustment of potentiometer coupling, (2) adjustment of the ancillary resistors, (3) connection of resistors from the potentiometers sliding contacts to one side of the power supply and (4) connection of a resistor between the two sliding contacts. A second embodiment, Fig. 2, employs a single variable resistor r connected between fixed resistors W and R. Desired relationships between the derived voltages may be obtained by the addition of voltage dividers, as shown, for example, in dashed lines. A third embodiment is shown in Fig. 3 and a fourth in Fig. 4 where resistors 30 and 32 are small compared with 31. The Specification discusses the design of the network shown in Fig. 2 and includes typical component values for each of the networks shown in Figs. 2, 3 and 4. Specification 475,728 is referred to.

The clay article, which is moulded with a splayed flange and slightly higher than required, is placed in the disc g<2>, which is then lowered until the article makes contact with the chuck and revolves with it. The arm 10 then automatically falls, and the projection 14 engages the bell-crank lever 15, thus causing a knife Y to cut off the surplus clay from the edge of the article, which is then rounded off by a spring-controlled tool 2 adjustably mounted in a groove in the plate 32. The disc g<2> is automatically raised to eject the finished article, by a cam 30 which actuates a slide 18 connected to the rod g by a lever 22, Fig. 3, loosely mounted on the shaft s. The chuck e is rotated intermittently by the slide o, Fig. 5, so as to engage the rope p between the pulleys g, h, and release the brake j from the pulley h. The slide o is reciprocated by means of a two-armed lever r mounted on the rocking shaft s and actuated by a cam 1 on the main shaft c. Forward motion of the slide o is assisted by a weighted guide-pulley 5 and spring 9. The arm 10 is automatically lowered by means of the cam 20 which reciprocates a lever E<2>, thus causing the rocking shaft s to rotate and lower a lever c and thus tighten the cable 11.
Patent GB-946143-A (GB)
Title: Process for the conversion of complex organo-aluminium and organo-boron compounds
IPC: C25B3/13
Filed: 1961-06-06
Abstract: <FORM:0946143/C2/1> Potassium organo-boron and/or organo-aluminium complex compounds are obtained by reacting melts or solutions of the sodium compounds with potassium amalgam. The products are useful as electrolytes in the electrolytic production of a metal alkyl, e.g. tetraethyl lead and triethyl aluminium. Compounds used include:-Na[AlR4], Na[AlR3H], Na[AlR3OR1], Na[AlR3X], Na[Al2R6X], Na[BR4], Na[BR3H], Na[BRnOR1m] in which R and R1 are hydrocarbon radicals, X is F, CN, or N3, and n and m together equal 4 and may be 0 or an integer from 1 to 4.  In the drawing sodium hydride is formed in reactor 1 from sodium and hydrogen.  This is treated with trialkyl aluminium and then ethylene to give sodium tetraalkyl aluminium. This is passed to exchanger 3 in which it is passed in counter current to a sodium amalgam containing some potassium to produce potassium tetraalkyl aluminium which is then passed to electrolytic cell 6. Electrolysis gives trialkyl aluminium and potassium in the amalgam. If a lead anode is used tetraalkyl lead would be produced. The amalgam is recycled to exchanger 3.  To prevent overconcentrating the amalgam with sodium, a portion is cycled through cell 11 and the sodium obtained is then returned to reactor 1, the mercury being returned to cell 6. 3/4 of the trialkyl aluminium is recycled, the remainder being withdrawn.ALSO:In the production of metal alkyls by electrolysis, the electrolyte consists of complex aluminium-organic and boron-organic compounds of potassium which are obtained by treating the corresponding sodium compounds with potassium amalgam. In the production of trialkyl aluminium, a compound K[AlR4] is electrolyzed between an aluminium anode and a sodium amalgam cathode. Trialkyl aluminium is obtained at the cathode while the amalgam, now containing potassium, is recycled through an exchanger containing Na[AlR4] at such a rate that the potassium content of the mercury is below 0.1% and the sodium content at 0.5-1%. In the production of tetraalkyl lead, the electrolyte may be a mixture of K[Al(C2H5)4] and K[Al(C2H5)3F] to form tetraethyl lead and K[Al2(C2H5)6F] at the lead anode and potassium amalgam at the cathode.  After separating off tetraethyl lead the electrolyte is regenerated by treatment with sodium hydride, ethylene and is stirred with the potassium amalgam at such a rate as to maintain the potassium and sodium concentrations in the amalgam at the values stated above. To prevent overconcentrating the amalgam with sodium a second cell may be used to remove sodium.

Title: Improvements in or relating to hinges
IPC: B21H7/00
Filed: 1930-07-07
Abstract: 350,757. Making hinges. BUDD MANUFACTURING CO., E. G., 2500, Hunting Park Avenue, Philadelphia, U.S.A. -(Assignees of Eksergian, C. L. ; 12141, Charlevoix Avenue, Detroit, Michigan, U.S.A.) July 7, 1930, No. 20528. Convention date, July 24, 1929. [Classes 83 (ii) and 83 (iv).] Rolling ; shearing.-Hinges are rolled from heated bar stock by passing the stock, cut to length, between cylindrical rollers 20, 21, one of which carries a die tooth 37 and the other a die pocket 32 as shown in Fig. 2..The blanks are fed into the rollers which bite into the ends 47 of the blanks. The surface of each die is recessed at 22 to a thickness of half the hinge shank and the shank is formed by extrusion of the metal into these recesses. The rollers rotate at the same speed but a differential rolling action is produced by making the roller 21 of greater diameter than the roller 20. The knuckle of the hinge is then formed by the radial movement of the tooth 37 entering the recess 32. During the initial radial movement of the tooth, which forces the end of the blank into the pocket to shape the outside of the hooded knuckle and the ears 19, the blank is anchored by a bulge of metal 48. One side 40 of the tooth 37 is the same shape as the pocket 32 but the other side 43 is cut away as far as a point 41a on the pitch circle 44 of the tooth. As shown in Fig. 3 the inward radial movement of the tooth is a rocking action about the point 41a. In the outward movement which is a rocking action about the pocket edge 56 on the pitch circle 45, the interior of the knuckle is rolled to size as shown in Fig. 7. The pitch circles 44, 45 of the tooth and pocket are equal in diameter and thus the rolling action during the formation of the knuckle is not differential as in the case of the shank. Fig. 13 shows the complete machine in which the bar stock 68 is fed into reciprocating cutting dies 70 operated from an eccentric 71 driven by gearing 72 from the roll axis 62. The severed blanks are dropped on a trackway 73 and are brought up to the rollers 20, 21 by a finger 75 which is oscillated in timed relation to the rollers by means of a cam 77.
