Title: Improvements in and relating to Disc-type Assemblies for Friction Clutches
Inventor: UPTON RALPH ANTHONY
IPC: F16D23/14
Filed: 1968-01-18
Abstract: 1,184,415. Friction clutches. AUTOMOTIVE PRODUCTS CO. Ltd. 20 Dec., 1968 [18 Jan., 1968], No. 2871/68. Heading F2C. A diaphragm clutch spring assembly includes a thrust ring 15 and a sleeve 20 having a flange 22, the ring and the flange being so shaped that some of the radial fingers 12 of a diaphragm spring 10 of conventional form are deflected relative to others of the fingers in the direction of the axis of the assembly. Fretting and resultant noise are stated to be substantially eleminated. In Fig. 3, the flange 22 is of circumferentially undulating form so that parts 23 of the flange are closer a rounded annular surface 17 of the thrust ring 15 than are the intervening parts 24. Alternate fingers 12 which bear on the flange parts 23 engage in radial slots 18 formed in the ring 15. The sleeve 20 is located in the ring by staking into a groove 26 at points 25. In a modfied sleeve, Fig. 5 (not shown), the flange (22) is sheared along radial lines and the parts (23) are bent out of alignment with the parts (24). In Figs. 6, 7 (not shown), a thrust ring (31) has upstanding ribs (33) for engagement with a number of spring fingers (34). Notches formed in a flange (36) of a sleeve (35) locate these fingers. The remaining fingers (34) are held in contact with a surface (32) of the ring (31) by un-notched portions of the flange (36). A rib (38) in the sleeve (35) prevents rotation of the sleeve in the ring (31).

Title: Process and apparatus for separating mixed liquids of different volatility
IPC: C10G7/00
Filed: 1923-01-31
Abstract: 193,030. Rialland, A. J. M. Feb. 7, 1922, [Convention date]. Distilling processes; hydrocarbons, distilling; rectifiers.-Miscible liquids, for example mixtures of petrol and lubricating oil from the crankcase of an engine, are separated by atomizing the mixture, which may be preheated, into a gas or into the vapour of a liquid such as water, with which the constituents of the mixture are not miscible, and passing the atomized mixture through a tube divided into regions of progressively lower temperature in which different fractions are separated. The liquid is drawn up a pipe 17 from a jacketed container 16 and is atomized by a jet of gas or steam from a pipe 2 into a tube 1 divided into zones by baffles 8. The zones are surrounded by jackets 3, 4, 5, through which steam is passed in succession. The steam is allowed to expand in the connecting pipes 6 so as to obtain successively lower temperatures in the jackets. Liquids collecting in the zones are withdrawn by pipes 9 to separate receivers 10. The tube 1 opens into a cooler 11 which receives a spray of water, and from which water is withdrawn by a pipe 13 and the volatile condensed liquid by a pipe 15. The zones of different temperature may be obtained by surrounding the tube 1 with a heating- coil the spirals of which are closer together at the inlet end than at the outlet end. The diameter of the tube constituting the coil may also increase towards the outlet end.

Title: Improvements relating to packetting machines
IPC: B65B43/50
Filed: 1950-02-06
Abstract: 686,552. Packing. AUTOPACK, Ltd., LEE, G. A., SMITH, A. R., and HOPKINS, C. J. April 10, 1951 [Feb. 6, 1950], No. 2972/50. Class 94(i) [Also in Group XXX] A machine for packeting small measured quantities of seeds or other granular or powdered material in envelopes comprises in combination a pair of work-tables which are intermittently rotatable about substantially vertical axes, and are each provided with a plurality of envelope clips whereby the envelopes can be releasably attached to the corresponding tables for movement therewith, an oscillatory carrier whereby envelopes released by the clips on one of the work tables can be transferred in succession to a position adjacent to the other work table, and means for raising the carrier to bring the envelope occupying the said position into another position in which it can be engaged by one of the clips on the last mentioned work table. A work table a is intermittently rotated by an oscillating cam e which serves also to move plate-like clip members o, by means of spring-urged pawls g, to grip an envelope c against the edge of the table. The table a carries the envelope through filling and gumming stages after which it is transferred by an oscillating carrier p to a similar work table b for sealing the filled envelopes. The carrier p is pivoted at its lower end to a horizontal arm q secured on a shaft r adapted to be oscillated by linkage means 7 controlled by a cam 8. Adjustably secured to the carrier p is a member s carrying an envelope-supporting platform t, which may be pivoted to the member sand held in position by a spring 11, a roller 12 on the platform t contacting a stop 13 to move the platform down on the first part of the movement of the carrier p away from the table b. Also on the carrier p is a slide u carrying a blade v. In operation, when an envelope c has been released from the table a to drop onto the carrier p, and table t, positioned below, a linkage y is moved by a cam w to rock a bell-crank x, pivoted to the carrier p, and through a link z to move the slide u upwardly so that the blade v extends beyond the upper end of the carrier p, frictional resistance means 2, 3 meanwhile holding the carrier p still. When the slide u has reached its extreme position the carrier p is then moved against the frictional resistance to a position below a clip o on the table b, the blade v co-operating with the clip to fold the flap of the envelope over, the envelope being supported by a stop 6. The carrier p is then raised by the link 7 to push the envelope between the clip o and the edge of the table b, which then clamp the envelope and the carrier is withdrawn. Specification 686,551 is referred to.

Title: Improvements in or relating to Spiral Lock-Seam Tubing
Inventor: JENSEN ERLING
IPC: B21C37/12
Filed: 1966-01-24
Abstract: 1,174,232. Making helically seamed tubing; corrugating. SPIRO INVESTMENT S.A. 2 Feb., 1967 [24 Jan., 1966], No. 3174/66. Heading B3E. [Also in Division F2] A machine for producing, from continuous metal strip, locked seam helical tubing, includes a head having an internal surface shaped to define the helix pitch and adapted to guide the metal strip into a helical path so that after a single turn of a helix marginal parts of the metal strip is brought into mating relationship, pinching rollers for gripping between them the marginal parts of the strip when they are in mating relationship, and feed and preforming rollers for feeding the metal strip to the head, for forming at least one longitudinal corrugation in the strip and for forming complementary inter-engageable marginal parts along the strip. A metal strip is drawn between flat guide plates and then between forming rollers 8 which corrugate the strip longitudinally, flange one edge and form a channel along the other edge, in preparation for the lock-seaming operation. The rollers 4 and 5 which draw the strip through the forming rollers, then push the strip over a grooved guide plate 22 into a forming head 3 which makes one complete turn. Strips 46 are let into the plate 22 in alignment with the lands and guide the strip so that it emerges axially from the head as rotating locked seam helical tubing, having external corrugations. To produce internally corrugated tube the rings 41 are formed on the lower roller 8 and the grooves 42 in the upper roller. Several pairs of forming rollers may be provided to corrugate the strip either by drawing so that the strip width is not reduced, or by forming so that the strip decreases in width. In the latter case the edges are shaped after the corrugating has been completed. The completed tubing is cut into lengths which are used as couplings for joining lengths of spirallywound locked seam tubing, the seam being accommodated in one of the corrugations, Fig. 7. Where the tubing to be joined also has corrugations, these corrugations are accommodated in additional corrugations provided on the coupling member, Figs. 8 and 9 (not shown).

Abstract: 305,104. Renker, M., Renker, G., Renker, H., and Renker, A., (trading as D³rener Prõparierter Papier Renker & Co.). Jan. 30, 1928, [Convention date]. Diazotype processes.- Papers sensitized with diazo - compounds are developed by treatment, preferably of the sensitized side only, with an excess of developing liquid such as a solution of ammonia, followed by the immediate removal of the excess of liquid by blowing it off with warm air. The developing liquid may be applied by spraying or by brushes, or by passing the paper through the liquid. The Specification as open to inspection under Sect. 91 (3) (a) describes also apparatus for carrying out the process, comprising a casing a enclosing two co-acting rollers b, c, the pressure between which may be adjustable, and a trough f containing developing liquid in which the roller b rotates. The exposed paper strip h is fed into the casing over the roller c and is guided between the rollers b, c. Rotary brushes w, n, prevent its adhering to either of the rollers, and direct it towards the exit aperture of the casing. In the casing, it is subjected first to the action of a mass k of developing liquid carried up by the roller b, and then to pressure between the rollers b, c, which removes excess of liquid. A travelling rubber or cloth band may replace the brush n; or both brushes m, n may be replaced by cloth-covered or grooved rollers or drums, or by compressed-air jets located within the rollers b, c and acting through perforations in the roller surfaces. Adhesion to either or both of the rollers may also be prevented by forming their surfaces of rubber &c. provided with projections or grooves. It is also stated that more than one pair of squeegee rollers b, c may be provided; and that the upper roller c may be replaced by other pressure devices. It is further stated that the paper may be sensitized with 3- dia.zo carbazol, and developed with an ammoniacal solution of the sodium salt of #-naphtholsulphonic acid. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 211,918.
Patent GB-451237-A (GB)
Title: Improvements in or relating to carrier wave transmitting apparatus
IPC: H03C1/62
Filed: 1935-02-01
Abstract: 451,237. Valve modulating systems. STANDARD TELEPHONES & CABLES, Ltd., STRONG, C. E., and McLEAN, F. C., 63, Aldwych, London. Feb. 1, 1935, No. 3391. [Class 40 (v)] In a modulating system of the kind in which the carrier wave amplitude is varied in accordance with changes in signal volume, this is effected by influencing the plate circuit of the modulated carrier amplifier by voltages varying with the signal volume and at syllable frequency. As shown in Fig. 2, speech is amplified by a push-pull pair of valves V3, V4 biassed to operate as a Class B amplifier, and the speech output voltage is applied through a transformer T2 and blocking-condenser C3 across the plates and cathodes of the carrier amplifiers V1, V2, thus producing a modulated carrier in the output circuit and aerial. The direct current through the valves is varied by including the plate-cathode paths of the carrier amplifiers V1, V2 in series with the plate-cathode paths of the speech amplifiers V3, V4 and with a choke L1. Owing to the biassing of the grids of the valves V3, V4 the direct current therethrough varies according to signal volume and at syllable frequency, and the series connection of the valves causes these variations to be imposed on the carrier amplitude. Rectified signal voltages may also be applied to the grids of the valves V3, V4. In a modification shown in Fig. 3, the speech is plate-modulated on the carrier by the valves 2, and is rectified at 5 and applied at 4 to vary the voltage of the D.C. source 3 for the modulated amplifiers 1. When the source 3 is a mercuryvapour rectifier, the voltage derived at 5 may be used to vary the phase of a grid control element. Alternatively this control voltage may be derived from the plate current of the amplifier 2 if this is of Class B type. Specification 283,264, [Class 40 (v)], is referred to.

Title: Improvements in or relating to the manufacture of self-locking screw threaded metal articles
Inventor: GEYER JOHN HENRY
IPC: F16B39/34
Filed: 1959-02-02
Abstract: Screw-threaded metal articles are rendered self locking by treating the threads of one or both with a chemical coating solution so as to deposit on said threads, before the articles are screwed together, a chemical conversion coating of a loosely-adherent, brittle and slightly powdery nature which can be dislodged by scraping.  When the articles are tightened it is said that the coating breaks down to a powder which increases the friction between the threads to such a point that they cannot be unscrewed.  Where the articles are of aluminium or aluminium alloy, the coating solution may contain from 0.6 to 12.5 gms./litre of fluoride ion, from 3 to 60 gms./litre of hexavalent chromium calculated as CrO3, and from 2 to 285 gms./litre of phosphate calculated as PO4 and/or pentavalent arsenate calculated as As2O5; and is applied to the articles for longer periods than 180 seconds and/or at higher temperatures than 130 DEG F.
