Abstract: 668,689. Universal joints. U.S. UNIVERSAL JOINTS CO. April 24, 1950, No. 10060/50. Class 80 (ii). A universal joint comprises a plurality of resilient bushings 10 each having a rigid circumferential shell 11, a central connector stud 13 and a body of resilient material 12, such as synthetic or natural rubber, secured to both stud and shell. The bushings 10 are arranged symmetrically with their shells 11 touching, and are mounted in a central carrier 16 having'threaded openings 17 into which studs 18 may be screwed in order to draw the wedge members 20 inwardly. Both the wedge members 20 and the central carrier 16 have edges curved to the shape of the bushings 10. The studs 18 pass through the apices of the wedge members 20 and also through holes drilled in the shells 11, and thereby prevent endwise displacement of the resilient bushings 10. Driving and driven members may be connected to opposed centres of the studs 13 on opposite sides of the assembly or alternatively all the studs may extend on the same side of the assembly for connection to either the driving or the driven member, the other member being connected to the studs 18. The resilient material 12 in the bushings 10 may be pre-loaded to provide the requisite resistance to movement of the connector studs 13 relative to the studs 11.

Title: Improvements in and relating to the production of printing plates or cylinders comprising both half tone and whole tone subjects
IPC: G03F5/20
Filed: 1925-04-17
Abstract: 235,152. Philippe, L. L., and Luginbuhl, H. June 6, 1924, [Convention date]. Photo-mechanical printing surfaces. - In the production of printing surfaces comprising half tone pictures and text or other line work, the method of adjusting the printing value of a halftone diapositive relatively to that of the text matter subsequently combined therewith so that only a single reproduction stage for exposing the etching resist and only a single etching may b necessary, consists in dyeing or colouring the half-tone diapositive, scraping away the gelatine surrounding the picture, and attaching to these parts a thin transparent sheet having the letterpress or whole tone matter thereon. The colouring or dyeing may be done before or after drying the diapositives and either chemically or by powdering. In addition to colouring the diapositive, and to avoid etching too deeply thick lines (e.g. thick characters, titles, &c.), these parts of the text may be printed in slightly transparent ink. In the Specification as open to inspection under Sect. 91 (3) (a) reference is made to other methods involving more than one exposure operation in the printing of the etching resist, or a dual etching operation, or the use of marks and varnishes for the different kinds of matter. This subject-matter does not appear in the Specification as accepted.

[Class 55 (ii).] A scrubber standpipe for horizontal gas retorts has a liquid-sealed valve arranged above and below the connection with each retort so as to isolate a length of the standpipe and the associated retort which is to be charged from the rest of the standpipe into which the remaining retorts are delivering. A two-unit standpipe serving two vertical rows of retorts 9 and connected to a hopper-shaped pipe 2 leading to a main 5 comprises superposed sections 10 each with a transverse vertical partition forming front and rear gas passages 8, 7. The outlet neck 9<a> of each retort is secured round an opening 11 in the outer lateral wall of a corresponding section conducting gas into the front passage 8. A valve 16 co-operates with a rim 14 at the top of each section to form when closed a liquid seal and carries loosely a valve 21 adapted to seat on the retort opening 11 as a sealing-off valve when the retort is to be isolated for scurfing or other longer operations. An external lever is held by a gravity catch to maintain the valve 16 in closed position, by a stop in an inclined inoperative position and by a screw-bolt in a vertical position to force the valve 21 on its seating. A retort is isolated from the standpipe for charging by closing the valves 16 directly above and below its opening 11. Gas from higher retorts meantime passes upwardly via the front passage 8 into the rear passage 7 whence it descends to the main. Tangential sprays are preferably arranged over each of the gas passages. A modified standpipe embodies both units in one pipe having a T-shaped web providing two front passages and a single rear passage. In addition to the spray nozzles a visible feed supplies an overflowing central trough with notched &c. fins to break up the liquor. The standpipes may bo operated as ascension pipes.

Title: Improvements in thermionic valve circuit arrangements
IPC: H03B5/28
Filed: 1945-04-24
Abstract: 597,652. Valve amplifying and generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and PARTINGTON, G. E. April 24, 1945, No. 10321. [Class 40 (v)] A valve circuit, for producing oscillations or amplifying selectively, comprises a network, consisting of a resistance R1 and condenser C1 in series with a parallel arrangement of condenser C2 and resistance R2, electromagnetically coupled to the anode-cathode circuit of the valve, the grid being connected to a point on resistance R2. The connections and couplings are such that at the frequencies concerned the grid and cathode potentials are in phase or the grid and anode potentials are in antiphase. The valve operates as a cathode follower, the transformer T having a step-up ratio, between the primary, carrying the cathode current and the secondary, sufficient to overcome the attenuation in the network. By employing a diode D and a resistance and condenser (at point X), the amplitude of the oscillations may be stabilised. A further resistance may be added in series with the network, Fig. 5 (not shown), across which a locking'signal may be applied. The grid may be biassed by a grid condenser and resistance or a cathode resistance, Figs 6 and 7 (not shown), and transformer T replaced by an auto-transformer. By adjusting the tap on resistance R2 so that the circuit is not quite oscillating, the circuit will amplify selectively frequencies near the frequency at which it would oscillate.

Title: Improvements in or relating to the manufacture of bags, packets, envelopes and the like
IPC: B31B23/00
Filed: 1932-04-11
Abstract: 401,686. Making paper &c. bags &c. STRACHAN & HENSHAW, Ltd., SARGENT, T., and FRENCH G. W., Whitehall, Bristol. April 11, 1932, No. 10362. [Class 94 (ii).] A method of manufacturing bags &c., of the kind wherein the bottom closure is effected by glueing the inner surfaces of the bag together, includes drawing web material continuously from a reel, glueing that surface which is to be the inner surface of the bag transversely at predetermined distances apart, corresponding substantially to the length of the bag, folding the glued web into a flat tube and severing the latter transversely adjacent to or along the transverse streaks of glue. A web of paper &c. b from an adjustable reel a is drawn through punches c, which punch thumb-opening notches 16 along the web, past guide rolls by friction-acting draw rolls f. The under surface of the web is then pasted at h to the form shown in Fig. 3, 10 being a continuous longitudinal edge streak and 11 transverse interrupted streaks the distance apart of opposite streaks being equal to the width of a bag. A folder j, of width of a bag, carried by a flat spring k, out of contact with the transverse streaks, creases the web longitudinally the edges being folded under and pressed by the draw rolls l. The separate bags are severed from the stuck tube by knives ml, m' and the rolls n feed the bags to forwarding tapes o. The already-stuck bag bottoms are again streaked with glue, folded over and pressed by the apparatus p. Delivery tapes q forward the completed bags to a belt t, the bags being pressed thereon by a roll r. The longitudinal folds over the device are in the first place formed by hand. A device 30, 31, 32, pivotally movable about 31, Fig. 6, may be used if there is evidence of " spreading " of the folded web. The method is stated to be particularly applicable to the manufacture of bags &c. of regener. ated cellulose &c. films since a clean cut top and bottom, devoid of serrations, is produced on each bag &c. Printing apparatus may be incorporated at any suitable part of the machine. Specifications 277,095 and 277,262, [both in Class 94 (ii), Paper bags &c.], are referred to.

Title: Improvements in or relating to plants for hydraulic control
IPC: B64C25/22
Filed: 1938-04-05
Abstract: 514,429. Pneumatic transmission systems. OLAER PATENT CO. April 5, 1938, No. 10387. Convention date, April 5, 1937. [Class 8 (ii)] [Also in Group XXIX] A hydraulic transmission system particularly for the control of retractable undercarriages on aeroplanes, is provided with an auxiliary pneumatic control acting under difference of pressure in a reservoir which has a slidable partition and on the respective sides of which are the main pressure and the .auxiliary system, the changeover being effected automatically by valve means in proximity to the undercarriage gear. Liquid from a reservoir 1 is passed by the pump 2 through a chamber 4 into a space 6 below a slidable partition 5 and thence through a control valve 11 and pipes 30 or 14 to the units 19, 20 operating the retractable undercarriages. For lowering the carriage, the pipe line 14 with its branches 15, 16, and inlets 24 forms the pressure line. Should, however, the pressure fail or fall, then an auxiliary air pressure in the space 7 may be brought into use by opening the valve 28 when the pipe line 27 and its branches 22, 23 become operative since the valves 25 are then opened up against the pressure of the spring 26 only, whereas before the valve was maintained in position by the spring 26 and the liquid pressure in the other circuit. If desired, the air pressure in the upper pipe line 27 may be used to produce action in an auxiliary hydraulic circuit so that the lines 22, 23 are then subject to a liquid column. The pipe system 30 for retracting the undercarriage is not provided with an auxiliary circuit, but may be if so desired.

Abstract: 375,898. Galvanic batteries. KUNZE, A., 72, Brandenburgstrasse, Berlin. April 8, 1931, No. 10415. Convention date, April 8, 1930. [Class 53.] In the production of galvanic cells, a rigid conveying means, serving, if desired, as inserting device, for example a revolving plate, takes up at one place an empty zinc container, brings it under a filling pump delivering electrolyte and, on further advancement, under a die which cuts a centring star out of a strip of material and inserts it in a retaining device over the zinc container, and, on yet further advancement, a carbon element is brought over the centring star, whereupon a press forces rod and star into the container, and the cell is passed to a heating bath. In the form shown, a switch star 16 passes zinc containers a from a transport band 13 to a revolving plate 1, where they rest on a guideway 1<1>. The plate brings the cans under the filling pump 2, then under a die which stamps out a centring star c and places it in a recess in the rotating disc 5. A carbon element from the conveyer 17 is supplied and, in several stages, pressed into the can, the guide way 1<1> being raised over this stretch so that the upper edge of the can is just below the disc 5, and the centring star is not displaced on entering the can. The finished cell g is now moved down an inclined plane by means of switch stars 21, 22 to the cooking bath, where it is held by Z-shaped guiding members driven by a chain 28 and of such a length that the distance D is equal to the distance E, whereby a smooth transference is ensured, and the removal of the cooked cell is effected in the corresponding manner.
