Abstract: 383,619. Mercury-vapour rectifiers. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. - (Assignees of Allgemeine Elektricitõts- Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Feb. 13, 1931, No. 4612. Convention date, Feb. 13, 1930. Void [Published under Sect. 91 of the Acts]. [Class 39 (i).] In a mercury-vapour rectifier or like apparatus which is permanently connected to a metallic vapour pump, the pump and the condensation surface of the rectifier or the like are so arranged and connected to one another that the mercury which is collected from the condensation surface during the operation of the rectifier is returned, at least in part, to the pump. In the example the rectifier 1 is connected by a tube 2 to the discharge end of a diffusion air pump 3, the lower end of which has a heating chamber 10. Mercury evaporated from the cathode 4 during the arc discharge condenses on a cooled surface 5 and is collected by a channel 6 provided with an outlet pipe 7 disposed above a container 8. The container 8 is connected to the heating vessel 10 of the diffusion pump by means of a pipe 9, and has an overflow outlet 11 in order to maintain approximately the same level of mercury in the pump, the excess of the condensed mercury being thus returned to the cathode 4. In a modification the pump is disposed within the interior of the body of the rectifier or the like.

IPC: H02K7/12
Filed: 1957-02-13
Abstract: 816,020. Induction motors with brakes. GLOBE ENGINEERING CO. Ltd. Dec. 17, 1957 [Feb. 13, 1957], No. 4870/57. Class 35. An electric motor has a conically tapering rotor 20 which can move axially along the motor shaft 16, and carries the movable portion of a brake. The brake may be applied, for example by an axial compression spring 24 which may be adjusted by a nut 26 on the motor shaft. The spring loading is overcome by tapering the rotor 20 and stator 22 from end to end and positioning the stator so that, on switching on, the stator field moves the rotor axially against the spring, thus releasing the brake. The rotor may have an inner sleeve 18 of phosphor bronze which is splined to the motor shaft. The movable portion of the brake may be formed on a fan 32 attached to the rotor and the fixed portion may be friction pads 38 secured to the end cover 36 of the motor.

Title: Improvements in or relating to a dispensing device
IPC: B30B15/30
Filed: 1955-02-18
Abstract: 781,509. Rotary moulding-machines. ARMSTRONG CORK CO. Feb. 18,1955 [March 19, 1954], No. 4903/55. Class 87(2). [Also in Group XVIII] A device for supplying a measured quantity of powder to mould cavities 4 moving in a circular path comprises one or more cavities 6 mounted on a plate 5 for rotation therewith to supply the material to the cavities 4, means 24 for supplying material to the cavities 6 and means for causing the cavities 6 to move synchronously with the cavities 4. The latter are carried by plungers 3 which engage a star wheel 2 adjustably connected to a shaft 16 having a slidably keyed pulley 17 with teeth 18 in engagement with teeth 19 on a sleeve 20. A plate 12 is attached to the sleeve 20 and imparts rotation to the plate 5 through bushings 13. Springs 23 tend to lift the latter plate and its height is determined by the setting of a ring nut 22 in accordance with the desired capacity of the cavities 6 which are filled with powder from a hopper 24 connected by a telescoping tube 28 to a shoe 29 loaded by a spring 30 to produce a wiping action between the shoe 29 and the plate 5. The powder is retained in the cavity 6 by a plate 14 having an opening 15 which allows the powder to flow into the cavity 4 when the latter is in alignment with the cavity 6. A screw 47 enables the dispensing device to be vertically adjusted with respect to the star wheel 2 while a threaded coupling 26 enables the tube 28 to be disconnected from the hopper 24 so that it may be moved out of position by swinging a bracket 8 around a column 9. The moulded articles, which may be bottle caps, buttons or bases for vacuum tubes, are removed from a force plug 33 by an unscrewing device. A detector 32 is engaged by the article if the latter sticks to the force plug so that a micro-switch energizes a solenoid 39 to raise the pulley 17 and disengage the star wheel 2 from the plate 5. The moulded article is thus brought into alignment with a cavity 6 from which the powder has already been discharged. A contact switch in parallel with the micro-switch may be used to halt the plate 5 when the machine is provided with more moulding stations than tools, the plunger on the station for which tools are not provided having a projection to actuate the switch. In a modification, each station on the moulding machine and the plate 5 contains two cavities. The plate 5 operates faster when it is not discharging powder and the contour of the star wheel 2 is changed to ensure correct registration of the cavities 4 and 6.

Title: Improvements in or relating to lubricating compositions
Filed: 1947-02-21
Abstract: A lubricating composition comprises a mineral oil having lubricating properties and a mineral oil-soluble polymer of cyclohexyl-styrene (see Group IV (a)).  The polymer is normally present in amounts of 0.1 per cent to 12 per cent by weight of the oil.  Oils specified in the examples are a light hydraulic base oil consisting of an acid-treated naphthenic gas oil and a heavy solvent-refined lubricating oil.  The compositions exhibit a decreased temperature coefficient of viscosity and the polymer inhibits the crystallization of the naturally occurring waxes present in mineral oils.ALSO:A lubricating composition comprises a mineral oil having lubricating properties and a mineral oil - soluble polymer of cyclohexyl - styrene.  Ortho-, meta- or para-cyclohexylstyrene may be employed and the polymer is normally present in amounts of 0.1 to 12 per cent by weight of the oil.  The polymer may be prepared in mass, in solution or aqueous emulsion with the aid of heat and/or catalysts such as peroxides, hydroperoxides and potassium persulphate.  Friedel-Crafts catalysts with, e.g. ethyl chloride as solvent, with temperatures of -40 DEG  to -10 DEG  C., may also be employed.  When polymerizing in solution, solvents such as toluene, xylene or cyclohexane are used and the concentrated polymer solution may be added directly to the mineral oil. Polymerization in the mineral oil itself may also be effected. To obtain a relatively pure polymer, it may be precipitated by pouring the solution into a non-solvent such as methyl, ethyl or propyl alcohol, washed and dried.

Title: Method and apparatus for handling sheet of stretchable material
Inventor: REID FRANCIS REGINALD
IPC: A21C3/00
Filed: 1962-02-13
Abstract: 977,713. Endless conveyers. PILLSBURY CO. Feb. 13, 1962, No. 5416/62. Heading B8A. Dough is fed in a strip D on a continuously moving endless conveyer 14 to a conveyer 33 mounted on a carriage 24 which is moved forwardly and rearwardly cyclically thereby to deposit the strip of dough on a third conveyer 10 which has an intermittent movement. The arrangement is such that there is no tendency to stretch the dough, the average speed of the conveyer 10 being equal to the continuous steady speed of the conveyer 14. The conveyer 33 comprises a series of laterally-spaced endless coil spring conveyer members 35 carried by two sets of pulleys 34 on respective shafts 29, 30, mounted on the carriage 24. Rigid with the shaft 30 are two driving spockets 36, 37. The sprocket 36 co-operates with a driving chain 48 (see also Fig. 4) which passes over an idler sprocket 45 mounted in the machine frame, a drive sprocket 47, an idler sprocket 43 mounted in the machine frame, and an idler sprocket 38 carried by the shaft 29 of the carriage 24. The driving sprocket 47 is driven by the same shaft 21 as drives a drive pulley 20 of the conveyer belt 14. The sprocket 37 of the shaft 30 is associated with a drive chain 54 (see also Fig. 5) which passes over an idler sprocket 40 mounted on the carriage 24, a drive sprocket 49, an idler sprocket 41 mounted in the machine frame, and an idler sprocket 39 carried by the shaft 29 of the carriage 24. The drive sprocket 49 is driven from the same drive shaft 13 as intermittently drives the conveyer belt 10. In operation the belt 10 moves for 240 degrees of a complete cycle and is staionary during the remaining 120 degrees. While the conveyer 10 is stationary the continuous drive of the shaft 30 by the sprocket 36 acts on the sprocket 37 to produce a translation of the carriage 24 to the left due to the fact that the chain 54 which is in engagement with the sprocket 37, is stationary. Thus the strip of dough is fed by the conveyer belt 14 on to the belts 35 of the conveyer 33, the upper runs of which are moving to the left (as viewed in Fig. 1), while the carriage 24 as a whole is also moving to the left. The strip of dough is thus being laid upon the stationary conveyer 10. When the conveyer 10 recommences the drive, chain 54 also moves in the direction of the arrow E and the effect of the drive of the two chains 54, 48, on their respective sprockets 37, 36, of the shaft 30, is to cause the upper runs of the endless belts 35 of the conveyer 33 to continue moving leftwards in Fig. 1 while the carriage 24 is moved rightwards.
