Abstract: 828,484. Toothed gearing; belt gearing. SCHIESS A.G. July 19, 1957 [July 30, 1956], No. 22875/57. Class 80 (1). [Also in Group IX] The adjacent coaxial sections of the long compound rollers or shafts in a spinning or other textile machine are coupled for rotation by toothed, friction, belt or chain gearing allowing any one section to be readily removed in a direction transverse to the roller axis without disturbing the other sections. As shown in Fig. 2, two roller sections 1, 1<SP>1</SP> are coupled by an offset wide coupling gear 3 which engages gears 2, 2<SP>1</SP> on the respective sections, the sections being mounted in bearing slots 6<SP>1</SP> so that either section may freely be lifted out. Ball or roller bearings may replace the plain bearings shown and the slots 6<SP>1</SP> may have removable covers. In a modification the coupling gear 3 additionally engages and couples two gears on the ends of a further pair of coaxial roller sections extending parallel to the sections 1, 1<SP>1</SP>. It is stated that a cleaning roller, provided at each end with appropriate gears, may be used to replace the action of a removed roller section. In the double belt drawing head shown in Fig. 7, a wide coupling gear 3 is engaged by a cleaning roller 16<SP>1</SP> which maintains the drive between coaxial delivery roller sections 17<SP>1</SP>. Adjacent coaxial roller sections 1<SP>1</SP> carry sprockets engaged by a wide coupling chain 19<SP>1</SP> which also drives sprockets on the rollers 5<SP>1</SP>, 12<SP>1</SP> of the lower belt unit. The upper belt unit may be lifted about the axis of the roller 5<SP>1</SP>. The sprockets on the roller sections 5<SP>1</SP> may be elliptical or eccentric to give a non-uniform motion so that the yarn produced resembles flake yarn. In a modification the roller sections 1<SP>1</SP> are replaced by sections of a feed drum. In a further modification, Fig. 6 (not shown), the chain 19<SP>1</SP> is omitted and the roller sections 1<SP>1</SP>, 51 are interconnected by a common wide coupling gear. It is stated that the coupling methods described allow roller sections to be used at either side of a machine (i.e. for right or left-hand drive) and allow them to be reversed to prevent uneven wear. The coupling methods also allow materials with different coefficients of expansion to be employed in a machine-e.g. the frame may be of light metal while the rollers are of steel.

Abstract: 1316845 Rolling mills USS ENGS & CONSULTANTS Inc 12 May 1970 [29 May 1969] 23006/70 Heading B3M As a strip passes through each four-high stand 14 of a finishing mill, lubricating is automatically supplied to the backing rolls of the mill, and thence to the strip, the supply being automatically cut off as the strip leaves the stand. The lubricant is fed from an oil supply 54 to headers 16, 18, 20 and 22 associated with the backing rolls of the stands. In addition, atomizing air is supplied to the headers, and also a further supply of "actuating" air for operating spray nozzles attached to the headers. Each nozzle, Fig. 4, has an oil outlet 40C, an atomizing air outlet 38, and a plunger 40. The plunger is moved to the right, to open the oil outlet, when actuating air is applied to a spring biased piston 42 coupled to the plunger. When the actuating air supply ceases, the plunger is closed by a spring 44. In operation, as soon as load cells 98 and 104 associated with the stands sense the presence of a strip 5, solenoid valves cause actuating air and atomizing air to cease, and the lubrication to finish. The lubricant is steam heated as it passes through the nozzles.

Title: Method and apparatus for testing the fluid-tightness of parts
IPC: G01M3/10
Filed: 1958-07-18
Abstract: 893,855. Testing hollow bodies for leakage. REGIE NATIONALE DES USINES RENAULT. July 18, 1958 [May 27, 1958], No. 23124/58. Class 106 (2). A method of testing the fluid-tightness of specimens 1, such as an engine crank-case, comprises creating a pressure difference between the interior of the specimen and the surrounding environment, passing any flow of gas tending to equalize the pressures through a liquid having a surface 9 exposed to the gas at an initial pressure and detecting bubbles due to the passage of the gas by causing them to break the contact between the liquid and an electrode 10 connected to an alarm circuit. The crankcase 1 of an internal-combustion engine is connected to a vacuum pump 2 by a flexible hose 3. Between the hose 3 and the pump 2 are two electro-pneumatically-operated valves 8, 11, and manometers 12, 13 are connected to the line between the valves 8, 11. In use, valves 8, 11 are opened and a vacuum is produced in the crank-case 1 by the pump 2. When the vacuum is sufficiently high, the mercury in the manometer 12 touches an electric contact 15 which is connected in the operating circuit of valve 11, thus closing this valve. After a few seconds the valve 8 is also closed. If the crankcase is not air-tight, the pressure in the hose 3 rises, and air bubbles are formed at an orifice o just touching the surface of water 9 in a container 7. These bubbles make and break the circuit formed between an electrode 10 and the water 9, thus causing a warning signal to be given. The device is so constructed that at least one make and break is required to give the signal, and thus a single perpetual bubble at the orifice o will not do so. Moreover, should the leakage be so great that a succession of bubbles flows, holding the electrode 10 continually insulated, the signal is given by the breaking of contact between an electrode 14 and the mercury in a manometer 13. A device is also described, Fig. 2 (not shown), for sealing a crank-case prior to testing.
