Title: Improvements in and relating to drive transmission devices and, in particular, to planetary drive transmission devices
Inventor: LAMBURN ALAN SALISBURY
IPC: F16D48/02
Filed: 1962-10-05
Abstract: 991,434. Controlling clutches; change-speed gearing; friction clutches. AXEL WICKMAN TRANSMISSIONS Ltd. Oct. 5, 1962, No. 37707/62. Headings F2C, F2D, F2E, F2F and F2L. The servo controlling means of a friction clutch is controlled by a torque responsive means to regulate the clutch engagement to a value at least sufficient for the transmitted torque. In a planetary overdrive gear having a plant carrier 53 splined to an input shaft 46, a ring gear 56 rigid with an output shaft 50 and a sun gear 57 splined to a cone clutch member 60 engageable with the ring gear 56 for direct drive or a brake 67 for overdrive, the clutch member 60 is urged to the direct drive condition by a series of springs 64. The spring force is modulated by fluid pressure in a cylinder 75 acting on a piston 65 interposed between the springs and the clutch member 60, the fluid pressure being inversely related to torque by a variable spring-rate relief valve 39; the valve being controlled by movement of a lever 36 from a collar 32 moved axially against a spring 29 by torque reaction in helical splines 59, connecting the sun gear with the clutch member, or by helical teeth in the planetary gearing. Rotation of a valve 71 covers fluid pressure to be admitted to an annular cylinder 73 to move a conical piston 67 to disengage the clutch member from the ring gear and to act as a brake on the clutch member for overdrive ratio. Under these conditions the engaging pressure of the brake is still determined by the balance of loading of the springs 64 and relief valve pressure in cylinder 75. The gearing may be used as an underdrive unit by reversing the roles of the input and output shafts. In simplified forms of the invention helical gearing, or helical splines, provide a torque sensing drive to a cone clutch which may be either spring engaged or spring released, the fluid pressure acting against the spring force.

Title: Process for accelerating the peroxidic hardening of mixtures of unsaturated polyester resins and olefinically unsaturated esters of phosphorus acids
Inventor: SCHMIDT HEINZ
IPC: C08F283/01
Filed: 1959-11-12
Abstract: The peroxidic hardening of mixtures of (1) phosphorus-free unsaturated polyester resins, which are polycondensates of olefinic polycarboxylic acids and polyhydric alcohols in admixture with olefinic comonomers, and (2) olefinically unsaturated esters of phosphorus acids is accelerated by addition of 0,001 to 10% by weight of the total mixture of at least one monoto tetra-isocyanate substituted hydrocarbon or heterocyclic compound having the formula R(N=C=O)x where x is an integer from 1 to 4 and R is an aliphatic, cycloaliphatic, aromatic or heterocyclic radical which may contain other substituents which do not react with isocyanates.  The polyesters may be derived from maleic, fumaric or itaconic, with or without adipic or phthalic, acids and ethylene or diethylene glycol. Specified comonomers are styrene, methyl styrene, vinyl acetate, chloracetate and propionate and acrylonitrile.  Phosphorus acid esters specified are allyl and methallyl esters of phosphorous, phosphoric and alkyl, cycloalkyl or aryl phosphonic acids. Isocyanates specified are octadecyl, dodecyl, cyclohexyl and phenyl monoisocyanates; tetra- and hexa-methylene, naphthalene and 4,41-dicyclohexyl-methane diisocyanates and the triisocyanate of leucorosaniline; the hydrocarbon radicals may be substituted by halogen, nitro or alkoxy.  Peroxidic hardening may be effected by dialkyl, diaryl, arylalkyl and acyl peroxides, hydroperoxides, per-acids and per-esters; methyl ethyl ketone p  peroxide is used in the specific example.  The compositions of the invention may be used as casting resins, coating products, lacquers, dispersions and adhesives.  They may also comprise fillers, e.g. silica, dyestuffs, pigments, plasticizers or reinforcing materials, e.g. glass fibres.

The latch device 66 comprises longitudinally spaced detent elements 70 on tie bar member 55 and a latch member 67 mounted on member 56 for engagement with the detent elements, and a latch retaining member 71 also mounted on member 56 to retain the latch member 67 in either a detent engaged position shown in full lines, Fig. 8, or a disengaged position shown in dotted lines. The latch releasing means comprise cams 88 and 86 to engage follower portions 83 and 81 of the members 71 and 67 respectively. Where the carrier supporting track 16 is inclined (for example, upwardly at 98, Fig. 11), the length of the carrier 18 is changed (in this case reduced) by gravity and the continued drive at the rear end of the carrier, when the latch device 66 has been released by cams 88 and 86 (after transfer of a load 24 to a conveyer 95). At a carrier length adjusting station, Fig. 12 (not shown), the driving dog (21) is disengaged from the pusher (22) by a carrier stop (100) so that the rear trolley assembly 27 stops, and the latch is released by cams 88, 86 moved into position by actuating cylinders (102, 103), but the front trolley assembly 26 is advanced by auxiliary pusher apparatus (104). After a length adjusting operation, the retaining member 71 meets another cam 88<SP>1</SP>, Fig. 11, to release the latch device from the retained position shown dotted in Fig. 8, and allow members 67 and 71 to return under gravity to the full line position engaging a tie bar detent element 70. Each trolley assembly 26 and 27 may comprise a single trolley or a plurality of trolleys, such as a pair as shown.

Abstract: 951,345. Phase detectors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 10, 1962 [Oct. 30, 1961], No. 38745/61. Drawings to Specification. Heading H3A. Two sinusoidal or similar waves are applied through respective impedances, e.g. resistors, each to a Zener diode connected to a common point, and the voltage difference between the rectangular pulses produced across the Zener diodes during their reversely conducting period is detected by an A.C. rectifier as a measure of the phase difference. A capacitor may be temporarily connected by a push-button switch between part of one impedance and the common point, to produce a phase lag, and whether this increases or reduces the meter output indicates which input wave is leading. Each diode may also be replaced by a series pair of oppositely poled Zener diodes.

Abstract: 405,180. Kinematograph films. HUBERT, K., 7, Nymphenburgerstras se Schoneberg, Berlin. June 19, 1933, No. 17465. Convention date, June 22, 1932. [Class 98 (ii).] The emulsion and substratum layers are chemically removed, without mechanical scouring as by brushes or scrapers, from old film material, such as worn kinematograph films, by passing the film band continuously with regulatable speed from a supply roll 9 first into one of a series of containers 15 ... 18 of the solvent liquid, preferably heated, through which the film is moved in numerous loops of fixed length, then, if desired, through a squeegee 19, then into a water tank 20 and between water jets 21, then against oppositely-rotating absorbent rollers 22, 23 covered with soft leather, and finally through a drying chamber 26 supplied continuously with cold air, to a take-up roll (not shown). As solvent liquid is used a diluted solution of soda lye containing a small quantity of hypobromite (prepared as by adding bromine to ordinary soda lye), which acts more speedily than the usual acid, alkali, or hypochlorite solution. By providing two or more paths through the apparatus, two or more films may be treated simultaneously and independently. The apparatus shown is adapted to treat two films, which are drawn from rolls 9, 9<1> by rollers 8, 8<1> ... independently chaindriven respectively from shafts 5, 5<1> ... which may be coupled through variable-speed gearing to a shaft 3 driven from a motor 1.
