Title: Improvements in the continuous polymerization of ethylene
IPC: C08F12/08
Filed: 1957-11-12
Abstract: Polyethylene is made by continuously polymerizing ethylene in the presence of a catalyst consisting of aluminium particles, a halide of a metal of Group IVa, Va or VIa of the Mendeleeff Periodic Table and, if desired aluminium chloride, and keeping the aluminium particles in constant movement during the polymerization so that the polyethylene formed on the surfaces of the aluminium particles is stripped off by a rubbing action between the particles and/or any other solid surfaces and separating the detached polyethylene.  The aluminium may be activated with a halogen or a halogen-containing compound prior to the polymerization, e.g. ethylene bromide, hydrogen chloride, or aluminium chloride.  The polymerization may be effected in the presence of a liquid diluent in which the halide of the metal is soluble but the polyethylene insoluble, e.g. by mixing vapours of the diluent with ethylene, and/or under pressures up to 200 atmospheres. Suitable metal halides are vanadium trichloride, titanium tetrachloride, chromyl chloride, and vanadium oxychloride.  Diluents mentioned are heptane, cyclohexane, benzene, ethylbenzene, and mixtures.  The aluminium may be in the form of balls, cylinders or cubes or coarse chips preferably with a diameter or an edge length of 5 to 20 millimetres.  The aluminium may be pure or alloyed with magnesium, silicon, manganese, iron, copper, or zinc.  In order to accelerate the separation of polyethylene from the aluminium particles, small steel or porcelain balls may be mixed with the aluminium.  When the polymerization is effected in bulk, the aluminium particles are charged into a vessel with a perforated sieve-like bottom which retains the particles therein, and a mixture of the ethylene and the vapour of the metal halide passed through the particles at a velocity such that the aluminium particles are kept in rapid motion and the separated polyethylene collected from the gas stream via a separator.  The polyethylene may be purified by washing with an alcohol.

Abstract: 1,152,752. Batching and packing eggs; endless conveyers. BEN NEVIS EGG EQUIPMENT Ltd. 16 Aug., 1966 [18 Aug., 1965], No. 35490/65. Headings B8A, B8C and B8H. Eggs, carried on an endless conveyer 1, Fig. 1, from a grader are individually gripped by arms 10 on an endless moving belt 2 and are transferred to a carrier 28 whereupon each egg is released into one of six positions on the carrier. When all six positions are filled by successive eggs, vacuum cups 40 grip and lower the eggs into one row of a carton 72. The arms 10, connected by a tension spring, close over the ends of the egg at position 10<SP>11</SP>, the arms previously being parted at position 10<SP>1</SP> by downwards movement of pins (19), Fig. 3 (not shown), against cams (25) on the arms, downward movement being effected by a striker (18) engaging on a ramp. When the egg is over channel 29<SP>1</SP> of the carrier 28 striker (18) engages on a fixed ramp (46a), Fig. 2, to part arms 10 and deposit the egg in the channel. This first egg, when on the conveyer 1, engages a flap (150), Fig. 6, to charge a memory unit (104), Fig. 4 (not shown), which, after a delay triggers the extreme left of five solenoids 42 (as shown in Fig. 1) to lower a ramp (46), Fig. 3, over the channel to the right of channel 29<SP>1</SP>, and thus to open the arms of successive members 10, some of which may not carry an egg, to deposit the next egg in the second channel. The remaining channels are successively filled in like manner and the final egg of the batch causes a clutch (110) to be engaged, thereby pivoting the egg carrier downwards and to the left in alignment with a series of cam-operated pushers (50), Fig. 3. At the same time a vacuum manifold (55), Fig. 3, is raised vertically and then turned horizontally so that cups 40 on the manifold align with the eggs on the carrier. The pushers (50) urge the eggs towards the cups 40 on the manifold which then withdraws the eggs horizontally and lowers them vertically into a row of cells in the carton 72. Vacuum to the cups is released, the pushers (50) are withdrawn and the carrier member is returned to its upper position ready for the next batch. An indexing conveyer moves the carton to present the next empty row of cells whilst the next batch of eggs is being carried by the vacuum cups. The extreme left of the ramps 46 may be permanently lowered if there are only five eggs per row in the carton. Drive for the whole apparatus is taken from an electric motor (75), Fig. 4.

Title: Fine mochanical adjustments
IPC: G02B27/40
Filed: 1930-11-26
Abstract: 367,860. Fine adjustments ; - optical interferometers. TWYMAN, F. and DOWELL, J. H., 24, Rochester Place, Camden Road, London. Nov. 26, 1930, No. 35615. [Classes 97 (i) and 97 (ii).] An object requiring fine mechanical adjustment is floated on its support through movable intermediate thrust members which engage both the object and the support by pivot engagement, and means are provided for rocking an intermediate member or so many of them as may be necessary to determine the location of the object, without altering the places of pivotal engagement. The Figure shows adjusting means for a rectangular body 1, enabling it to be turned independently about vertical and horizontal axes. An intermediate member 9 in the form of a horizontal bar is provided with pivots 10, 11 respectively engaging a conical recess and a V-groove in the support 2. A second intermediate member 14<1> is also provided with pivots 15, 16, similarly engaging the support and in line with the pivots 10, 11. The body 1 is supported on pivots 12, 19 on the members 9, 14<1> respectively and by a floating thrust rod 20 meeting the body at the intersection of the desired vertical and horizontal axes of movement, and engaging a part, not shown, of the support 2. The pivot 12 is also situated on the said vertical axis. The members 9, 141 have vertical extensions 13, 17, the member 13 being engaged by the end of a screw 14 passing through the support 2 and being also tapped. to receive a screw 18, the end of which bears on the member 17. Rotation of the screw 14 rocks both members 9, 14<1> together and causes the body 1 to turn about a horizontal axis through the point 21. Movement of the screw 18 causes the pivot 19 only to rock, the body being thereby adjusted about the vertical axis passing through the points 21, 12. Another form is described in which, in addition to the adjustments about horizontal and vertical axes, the body can be moved parallel to itself and normally to its surface without altering the angular setting. The invention is particularly intended for adjusting the reference mirrors &c. in the interferometer described in Specification 367,859.

Title: Improvements in or relating to braking arrangements for electric motors
Inventor: FRIEDLANDER ERICH SIEGFRIED
IPC: B66B1/12
Filed: 1956-11-21
Abstract: 809,713. Automatic speed-control systems. GENERAL ELECTRIC CO. Ltd. Nov. 21, 1957 [Nov. 21, 1956], No. 35616/56. Class 38 (4). [Also in Group XXXVII] An induction motor 1 is connectable to a three-phase supply for forward or reverse driving operation, provision also being made for direct-current braking operation. A servomotor 7 has windings 8 and 9 for respectively increasing and decreasing the rotor resistance 4. A mechanical brake 10 is applied by weight 11 and is lifted by fluid pressure under the control of governor 12 which may be set manually or automatically in dependence upon a desired motor speed. The winding 8 is energized in accordance with the rotor current, whilst the winding 9 is controlled by magnetic amplifier 17 having its control winding connected to resistance bridge 18. A variable tapping-point on resistor 20 is automatically adjusted in response to the fluid pressure in the braking system. The control current for the magnetic amplifier is thus dependent upon the mechanical braking effort, which is in turn dependent upon the setting of the governor. A polarized relay 22 is arranged to alter the stator connections of the motor 1 from driving to dynamic braking upon reversal of current in the control winding of the magnet amplifier, so that the driving or braking torque is adjusted to minimize the braking effort necessary for accurate speed-control. The fixed tapping- point on resistor 19 may be preset so that reversal of current takes place when the mechanical braking pressure reaches a predetermined fraction of the maximum braking effort. If the induction motor is used for a mine winder, a cam-operated switch is arranged to be opened as the winder approaches bank, thereby interrupting the automatic control circuit. This circuit may also be opened in an emergency. A switch 24 opens in the " off " position of the winder so that the rotor resistance automatically returns to its maximum value.
