Title: Improvements in or relating to High Pressure Internally Meshing Gear Pumps or Motors
Inventor: ECKERLE OTTO
IPC: F03C2/08
Filed: 1967-08-11
Abstract: 1,191,472. Gear pumps and motors. O. ECKERLE. Aug. 11, 1967, No. 36898/67. Heading F1F. An internally-meshing gear pump (or motor) comprising a driven externally toothed pinion 1, Fig. 2, an internally toothed ring gear 3 meshing therewith and a sickle-shaped filling piece 2 disposed between the gears and wherein the ring gear is mounted solely on the filling piece, includes pressure zones 6<SP>1</SP>, 7<SP>1</SP>, connected to and diametrically opposite the pressure chamber 6, 7 of the pump (or motor) so that resultant forces P R  , and T i , applied to the pinion and ring gear respectively are balanced by resultant forces -P R ,  h  and -P i , h  in the zones 6<SP>1</SP>, 7<SP>1</SP> respectively. Further, to avoid radial leakage gap losses and compensate for wear it is necessary for the pinion 1 to lie tightly against a part 9 and sealing edges 4, 4<SP>1</SP> or the filling piece 2 and the ring gear to lie tightly against a part 8 and sealing edges 5, 5<SP>1</SP> of the filling piece. To accomplish this it is necessary to apply a force P D , Fig. 3, vertically downwards on the ring gear which tends to urge the edges 4, 4<SP>1</SP> and 5, 5<SP>1</SP> on the filling piece farther downwards so that it becomes necessary for the circular arcs subtended between the edges 4, 4<SP>1</SP> and between the edges 5, 5<SP>1</SP> not to exceed 180 degrees resulting in residual forces # P R ,  h  and # P i ,  h  proportional to the tooth pitch acting on the pinion and ring gear respectively. The force # P R ,  h  may be ignored since it is taken by the pinion shaft bearing but the force # P i ,  h  needs to be compensated for. The resultant of the compensating force -# P i ,  h  and P D  is at an angle α, Fig. 5 to the horizontal and at this location a radial piston 13, subjected on its rear face to the pressure in the pressure chamber is disposed. A spring 14 provides the pressing pressure on starting and a bore 15 relieves hydro-statically the sliding between the piston and the ring gear. A slot 10 in the filling piece and a pin 11 fixed to the casing provides for downward movement of the filling piece. Recesses 16, 16<SP>1</SP> on the axial end faces of the filling piece reduces the contact surface between the piece and laterally adjoining elements. Axial sealing of the pressure chamber 6, 7 of the pump is effected by pistons 17, 17<SP>1</SP>, Fig. 7 (not shown) subjected on their rear faces to discharge pressure. Axial compensating pistons may also be provided in the vicinity of the pressure zones 6<SP>1</SP>, 7<SP>1</SP>, to compensate for the axial gaps caused by the pressure in these zones. In a modified embodiment, the separate axial pistons sealing the ends of the pressure zones and the pressure chamber are replaced by a single piston.

Title: Modified polysulfide composition
IPC: C08L81/00
Filed: 1962-10-01
Abstract: A liquid polyalkylene polysulphide is mixed with a curing agent which is activated by moisture and with a deliquescent accelerating agent which attracts moisture from the surroundings, e.g. the atmosphere, and so initiates the curing of the polymer. Alternatively, the polymer may be mixed with a curing agent which is also deliquescent. The curing agent may be an organic oxidizing agent or an alkali metal or alkaline earth metal peroxide or per-salt, or other metal peroxide.  The deliquescent accelerating agent may be an alkali metal or alkaline earth metal oxide, peroxide, hydroxide or salt of a weak acid.  Alkali metal and alkaline earth metal peroxides may be used as curing agents which are also deliquescent. Plasticizers and fillers may be mixed with the polymer, and its adhesiveness may be increased by mixing with phenolic and epoxy resins.  In examples polyalkylene polysulphides are mixed with calcium peroxide, barium oxide, zinc peroxide, sodium pyrophosphate peroxide, sodium hydroxide, titanium dioxide, calcium carbonate, a chlorinated diphenyl plasticizer, an epoxy resin, and toluene. Other ingredients are mentioned.

Abstract: 866,019. Control systems for incandescent lamps. SIEMENS-SCHUCKERTWERKE A.G. Nov. 29, 1957 [Nov. 29, 1956 (2)], No. 37308/57. Addition to 822,036. Class 38 (4). [Also in Group XXXVI] A stage lighting system as described and claimed in the parent Specification comprises a control panel having a plurality of readily replaceable units, each unit consisting of a number of pre-setting control levers associated with the requisite resistors and a scene-setting switch. A control panel (see Fig. 5) comprises a number of units 1 (see Fig. 3) each of which has four pre-setting control levers 12 movement of which levers move contact members 22 over wire-wound resistors 4, 4<SP>1</SP> thereby to vary the voltage applied to the contacts 45-48 of the scene-setting switch 6, these voltages being used to control the brightness of the lamps in the stage lighting equipment. In normal operation each of the pre-setting control levers 12 is housed below the surface of the unit 1 to prevent inadvertent operation thereof. In use a desired lever 12<SP>1</SP> is raised above the surface of the unit 1 by rotating a hand wheel 37 and hence a shaft 36 which causes a cam wheel to rotate so that one of its cams 32 ... 35 (as shown in Fig. 1, cam 32) to co-operate with a link 8 whereby the lever 12 is raised so as to project from the unit 1. The lever 12<SP>1</SP> may .now be moved to alter the position of the corresponding contact member 22 on the corresponding resistor 4 so altering the voltage applied to the corresponding contact in the scene setting switch 6. Further rotation of the cam wheel 32 ... 35 will select others of the levers 12. The scene setting switch 6 is operated by a hand wheel 60 through the medium of a shaft 58 and gears 56, 57. Electrical connection between the units 1 and the fixed wiring in the control panel is made by means of a number of contacts 7, the units being secured to the panel by screws 75, 76. In another embodiment the raising of a lever 12 out of the unit 1 may be accomplished by means of a cam rotating within a specially shaped aperture in a member corresponding to the member 8.

The jaws together comprise a helical coil, Fig. 3 which is only electrically completed when the jaws are firmly closed along all their length so that a cellophane tear or tab projecting between the jaws can reject the cigar C by cutting the circuit. In operation correct closing of the jaws 5, 6, Fig. 4 can make the circuit of a relay 17 across the jaws and move the blades 19, 20 to the position shown. When the jaws subsequently open the relay is held by a condenser 18 and a switch 21 is made but the reject solenoid 22 is not energized to reciprocate a plunger 7 as the blades 19, 20 are held switched over. If the circuit of the relay is however not made across the jaws as they approach one another because of say loose wrapping between the jaws, then the relay 17 is not energized, the blades 19, 20 are not moved to the position shown and subsequent making of the switch 21 as the jaws move apart causes current to flow in the solenoid 22 which operates the reject plunger 7.

Title: Improvements in or relating to tuning devices comprising a substantially circular line
IPC: H01F17/00
Filed: 1960-11-08
Abstract: 956,284. Tuning resonant transmission lines. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 8, 1960 [Nov. 11, 1959; April 16, 1960], No. 38321/60. Heading H1W. A tuning device comprises a resonant line wherein one conductor of the line comprises a circular first portion 5, Fig. 1a and a substantially circular second portion 2 extending concentrically around and spaced from the first circular portion, a movable contact member 6 providing a short circuit between the two portions, whereby the resonant frequency of the line can be varied by moving the contact member along a circular path so as to vary the position of the short circuit and thereby vary the effective length of the conductor. Preferably the first portion is disc shaped and forms part of a disc-shaped capacitor, a fixed connection 7 connects the two portions together. The two portions are held parallel to a conductive sheet 1, which forms the other conductor of the resonant line, by insulating spacers 3. As the tuning member is rotated, the capacitive end loading of the line is altered in such a way that a linear dependence of rotation and frequency is obtained. The lower frequency end may be extended, as shown in Fig. 5, by providing fixed inductances 22 which may be switched successively into circuit.
