Title: Improvements in or relating to composite driving belts
IPC: F16G1/04
Filed: 1930-04-16
Abstract: 349,246. Driving-belts. GUILLOU, H., 13, Rue Raymond, Montrouge, Seine, France. April 16, 1930, No. 12060. [Class 80 (i).] ] In driving-belts of the kind comprising an outer band of fabric, ordinary tanned leather, or other substantially non-stretchable material and longitudinal laterally-spaced strips of friction material such as spongy chrome leather impregnated with tallow, the latter are secured to the former while held under tension. The longitudinal spaced strips B are subjected to tension by braked friction wheels 1, 2 and are perforated by a punch 7 reciprocating in timed relation to the speed of travel of the strip. Uniformly spaced holes are thus formed so that the strip may be secured under corresponding tension by rivets, eyelets, clips, stitches, &c. to the substantially non-extensible outer layer, although, owing to the variation in elasticity of the strip, the holes may be non-uniformly spaced when the strip is not under tension.

Title: Improved liquid electrophotographic developer
IPC: G03G9/135
Filed: 1965-03-22
Abstract: 1,090,268. Electro-photographic liquid developers. DEPARTMENT OF SUPPLY, COMMONWEALTH OF AUSTRALIA. March 22, 1965 [March 23, 1964], No.12106/65. Heading G2H. A method of controlling the relative polarity of liquid developers for electrostatic printing consists in forming a developer by suspending pigment particles in an insulating carrier liquid adding a liquid control material with a dielectric constant different to that of the carrier liquid but soluble therein, agitating the liquids, and then applying the developer to the latent electrostatic image to be developed whereby the relative attraction between particles and image causes deposition in conformity with the changed dielectric constant. The developer polarity may be changed sufficiently to give image reversal, by the formation of ions in the following ways: - (a) the formation of small amounts of oxygen dissolved in the liquid media which oxidize the liquid dielectric, suspended material, or the image surface. (b) the presence of catalyst metals such as copper or iron which produce ionizing organic compounds. (c) the presence of nitrogenous compounds, amino and amino derivatives which donate electrons or accept electrons. (d) the photo-mechanical excitation of small gas pockets in the media. Alcohols, aldehydes and esters supply ions during the passage of ozone through the liquid. An aromatic. hydrocarbon liquid is ionized by dissolving therein 20 moles per litre of myristic acid, or by adding naphthalene or tetralin, and then passing ozone. Ionization is inhibited to increase resistivity by adding olefins such as cyclohexane or octene. Minor ionization is caused by adding large amounts of lanoline, naphthenic acid, or oleic acid. Small amounts of ethyl alcohol or dibutylphosphate also cause ionization in hydrocarbon liquids. Various proprietary substances are mentioned in examples given.

Title: Improvements in or relating to the forming of laps on lap forming machines
IPC: D01G27/00
Filed: 1954-04-27
Abstract: 758,870. Lap-forming apparatus. TRUTZSCHLER, H., TRUTZSCHLER, H., and MULLGES, C., [trading as TRUTZSCHLER & CO.]. April 27, 1954 [June 22, 1953], No. 12196/54. Class 120 (1). A lap being wound on a lap tube 16 under load from the heads of lap racks 15 is allowed to grow to a predetermined size in lateral guides 14, the lap then being raised with any interruption of the feed by means of projections 17 on the heads of lap racks 15 until the web is freely suspended, in which position a new lap tube supplied in the direction of feed again presses the web into the trough formed by lap rollers 13 and the web, which is thereby tensioned, is severed above the new tube by means of a knife 30 which moves rapidly forward on the opposite side of the web and simultaneously throws the oncoming cut edge over the new lap tube which the finished lap is conveyed via a runway 40 on to a lap-collecting table. As shown, when a desired yardage of of the fibre web V delivered by a scutcher has been wound, a counter 52 actuates a switch which operates a magnetic coupling to effect ejection of the completed lap and insertion of a new tube by the following operations: (a) brake pressure on the lap racks 15 is released and the racks are moved upwardly, whereby the completed lap is raised and discharged as stated above; (b) when the lap is raised in guides 14, rotation of a cam-plate 31 operates a lever system 56 to rotate feed discs 26 and feed a new lap tube into the trough between rollers 13, thereby tensioning the web connected to the lap; (c) as the lap tube reaches the roller trough, rotation of cam-plate 31 causes knife 30 to sever the web and start the winding of a new lap as stated above; (d) the lap racks descend to contact the new lap tube, brake pressure is re-applied, and knife 30 and levers 56 return to their initial positions under the action of springs 32, 57, respectively. The lap tube 16 is extracted from the completed lap by means of a tool 43 provided with stops 42 engageable with corresponding stops in the tube. The tube is then slid on to a bracket 20 which, on engagement of a trip by the end of the tube, tilts to discharge the tube into a magazine 21 down which it is conveyed by arms 25 of a conveyer 24 until it rests on feed discs 26. A press-button K enables the lapejection operation to be effected at any desired time, independently of the action of counter 52. The control may be operated from the counter hydraulically instead of electrically.

Abstract: 1,263,661. Sprinkler head. W. H. STOUT. 13 March, 1970. [18 April, 1969], No. 12228/ 70. Heading A1D. [Also in Division F1] Water is discharged through nozzle arms 24, 25 extending from a case mounted for rotation and limited up and down sliding movement on stationary stem 10. The case is in two rigidly secured sections, a lower section 15 defining an annular chamber 15' which receives water through ports 26 and an upper section 16 defining a chamber which receives water through inlet 13. In the position of Fig. 1 water cannot accumulate in the upper chamber since outlet port 27 is open. Water entering the lower chamber 15' exerts a constant pressure on wall 21 forcing the case downward to the position shown in Fig. 2. Sealing member 29 then blocks the outlet 27 and pressure builds up in the upper chamber, forcing the case up until the tension in spring 32 finally pulls the sealing member down and the Fig. 1 position is again reached. An arrangement of inclined resilient fingers 35 is secured to the top of the stem and engages teeth 38 on portion 16 to cause partial rotation of the case with each up and down cycle. In a modification Figs. 6-10 (not shown) an intermediate member (49), on which the sealing member (54) is mounted, can slide on inclined pins (55) attached to the stem (40). The up and down motion of the case is produced as before and when the case is raised the intermediate member slides up over the pins and is partially rotated. This rotation is passed on to the case since the member has teeth (57) which cooperate with sockets in the upper case during upward movement of the member.
