Title: Improvements in power transmission gearing
IPC: F16H47/04
Filed: 1951-01-15
Abstract: 692,056. Variable-speed gearing. DAIMLERBENZ AKT.-GES. Jan. 15, 1951 [Jan. 13, 1950], No. 1133/51. Class 80 (ii). In gearing wherein the input is split by an epicyclic gear C into two branches which are re-combined at the output by a second epicyclic gear D, the two branches are concentric and are interconnected through a hydraulic torque converter. The stepped planets of the two gears C, D are carried by the driving and driven shafts A, B respectively, the larger pinions 3 of gear C meshing with an annulus 4 connected to the sun 8 of gear D, meshing with the larger pinions 9 of gear D, through a central shaft 5, while the smaller pinions 2 of gear C mesh with a sun 6 fast on a hollow shaft 7 to which the annulus 12 of gear D is secured through a disc 14. Swashplates 19, 25 of adjustable inclination mounted on shaft 7 actuate the pistons 18, 24 of a hydraulic pump E and motor F forming a hydrostatic converter, the pump cylinders 17 being formed in a drum 15 fast on shaft 5 while the motor cylinders 23 are formed in the stationary housing G. Communication between the pump and motor cylinders is controlled by ports in the disc 14. If plate 19 is normal to shaft 7, with 25 inclined, the branch comprising the shaft 7 is held stationarv and a fixed reduced drive is transmitted through the branch comprising shaft 5. Shaft 7 may additionally be held by a brake 33. If plate 19 is inclined in one direction, a composite drive varying from reduced to overdrive is transmitted, depending on the inclination of plate 25 to one side or the other, shaft 5 being held stationary in the maximum overdrive position, in which it may additionally be held by a brake. If plate 19 is adjusted into the oppositely-inclined position, reverse drive is obtained.

Abstract: 353,824. Arranging cigarettes for packeting. UNIVERSELLE C I G A R - ETTENMASCHINEN-FABRIK J. C. MœLLER & CO., 48, Zwickauerstrasse, Dresden, Germany. Jan. 14, 1931, No. 1304. Convention date, Sept. 10, 1930. [Class 94 (i).] In order to arrange incorrectly disposed cigarettes into the correct positions for. packeting, a series of fingers for engaging the seam are arranged to operate in succession on successive cigarettes. As shown, the fingers c are mounted on springs d adjustably bearing on springs f by means of screws e. The springs are carried by.an arm k of a bellcrank lever k, k<1> pivoted at h on a disc q. The disc q is driven, for instance, by a. pin-and-slot drive, at a mean peripheral-speed equal to the liner speed of the chain b carrying the cigarettes a, but arranged to move slowly when a cigarette is passing beneath the disc and faster at other times. During the phase of retardation, the seam of an incorrectly placed cigarette engages the finger and rotates the bell-crank lever so that a circuit o is made or broken to operate any suitable apparatus for turning the cigarette. Instead of alternate rapid and slow motion of the disc, rotary motion with intervals of stopping or with short return movements may be used, and the finger may be used as a relay for a mechanical turning device. Alternatively, the finger may be used to effect the turning movement directly. In another form, the fingers are mounted on an endless belt.

Title: Electric motor control system
IPC: B66C9/16
Filed: 1962-01-17
Abstract: 988,053. Control of two A.C. motors. COMPAGNIE GENERALE D'ELECTRICITE. Jan. 17, 1962 [Jan. 17, 1961], No. 1769/62. Heading H2J. Two mechanically independent motors driving, for example, the rollers of a travelling crane which has to move on its tracks without skewing are electrically linked so that any fault on one motor tending to produce skewing will result in the interruption of the supply to both-motors. As shown, two star-connected motors M1, M2 are connected to power supply lines 1, 11, 21 over an isolating switch S, a reversing contactor having contacts 13, 14, 15 and 13a, 14a, 15a, and push-buttons 22, 23. The neutral points N1, N2 of the motors are connected by a conductor 19 which includes the winding 20 of a relay R1. With switch S closed, operation of push-button 22 causes current to flow through the circuit 1 to 11, of which 7 denotes the contactor coil operating contacts 13a, 14a, 15a and 9 denotes the normally closed contact of a relay R2, whereby the motors run in one direction; operation of push-button 23, energizing contactor coil 7a instead of coil 7, reverses the direction of rotation of the motors. If a fault develops in the operation of either M1 or M2 a potential difference is set up between the neutral points N1, N2 and current flows in conductor 19 whereby relay R1 is energized; its normally open contact a then closes to complete a circuit energizing relay R2, which is maintained energized by its contact b, so that contact 9 is thereby opened, thus cutting off the supply to coil 7 or 7a and opening the contacts of the reversing contactor to de-energize the motors. In a modification (Fig. 2, not shown), resistances are provided between the neutral point of the winding of each motor and the junction of conductor 19 with the motor winding.

Title: Improvements in or relating to fuel- resistant articles having low temperature flexibility and process for making same
Inventor: KIDWELL ALFRED SPILLER
Filed: 1955-01-21
Abstract: Polydimethylsiloxane rubbers containing from 1 to 2 chlorine atoms per silicon atom (from 33 to 49 per cent chlorine) are obtained by passing chlorine into a dilute solution of the uncured rubber of molecular weight at least 400,000 sufficiently rapidly to ensure that 5-40 per cent of the chlorine input leaves the solution, an inert gas in a quantity several times the volume of the chlorine also being passed through the solution to scavenge chlorine therefrom.  By this means substantial degradation of the rubber is avoided.  The temperature should be 100-180 DEG  F. and free radical activators such as organic peroxides may be present or the solution exposed to light.  The chlorinated rubber may be compounded with alumina and other fillers and peroxide curing catalysts and moulded into products which have good resistance to aromatic hydrocarbons and good low temperature flexibility.  Six examples are given of chlorination using various temperatures, freeradical inducing additives or light, nitrogen as scavenger and various curing cycles for the filled product.  The swelling of the products in an aromatic fuel is compared with the swelling of an unchlorinated rubber.  In Example (6) the properties of the cured product from a mixture of chlorinated and unchlorinated gums are investigated showing that a major proportion of chlorinated gum is required to give solvent resistance, while the presence of the unchlorinated gum improves the tensile strength.

Filed: 1926-01-23
Abstract: 264,021. Diem, H. Levy-. Jan. 23, 1926. Ornamenting. - Materials such as fabrics, paper, leather, cardboard, and wood are ornamented by treating the material with a substance which is sensitive to light, applying designs in one or more colours by printing or by hand, exposing the material to light, and fixing. Instead of exposing to light, a chemical medium may be employed which will precipitate silver from silver nitrate; also, in a modification, the light-sensitive substance is added to the ink or paint used in applying the designs instead of applying it separately. In the case of woven fabrics, the yarns may be ornamented as above before weaving. The material may also be partially exposed to light before the designs are applied. In examples, silk is subjected to a preliminary treatment with a mixture of ammonium chloride and an aqueous solution of Iceland moss, and is then steeped in a light-sensitive emulsion comprising either silver nitrate and citric acid or an aqueous solution of green ferric ammonium citrate and tartaric acid. After exposure, the material is treated in a combined gold toning and fixing bath.
