Title: Method for the production of a crystalline polyolefin
IPC: C08F10/00
Filed: 1963-09-04
Abstract: Polymers of 1-olefins are made by subjecting the monomer, in a polymerization zone, to the action of a catalyst consisting of a TiCl3-AlCl3 complex formed by the reaction of TiCl4 and Al, and in a finely divided form diethyl-aluminium chloride combined with an organic adjuvant, i.e. any material which will co-operate with the catalyst to produce a polymer having a lower pentane solubles content than would have been the result if no adjuvant had been employed under identical polymerization conditions.  The Specification contains a very extensive list of suitable adjuvants selected from (1) quaternary ammonium halides, (2) tertiary amines, (3) aryl ethers, (4) ketones and polyketones, and (5) phosphorous compounds. The polymerization may be effected in the presence of hydrogen. Specified olefins are propylene, 1-butene, 1-pentene, and 4-methyl-1-pentene. The catalyst may be "aged" at elevated temperature The polymerization may be effected in bulk, or in an inert diluent.

Title: Improvements relating to fluid cooled electrical apparatus
IPC: H01F27/28
Filed: 1953-12-23
Abstract: 738,365. Transformers and inductors. GENERAL ELECTRIC CO. Dec. 23, 1953 [Dec. 26, 1952], No. 35780/53. Class 38 (2). Electrical induction apparatus having ducting therein for the passage of cooling fluid has the ducting constricted at certain places so as to modify the flow of cooling fluid in such a manner as to enhance the cooling effect thereof. Cooling fluid is pumped into the casing 2 of a transformer 1 through a conduit inlet 14 and flows along a number of ducts 6, 8, 10, 12 associated with the transformer windings and ducts 20 associated with the transformer core, leaving the casing 2 by an outlet 15. Baffles 17 are placed in the ducts 6, 8, 10, 12 ; baffles 21 being associated with the core ducts 20. These baffles have the effect of creating turbulence in the flow of the cooling fluid, thus the cooling effect thereof is increased. The baffles may be of any suitable shape provided that they form constrictions in the ducts and at local hotspots the length of the constriction may be such that the fluid velocity at these points is increased. The spacing of the constrictions is such that in a succession of constrictions, each becomes effective to produce turbulence in the flow of the cooling fluid before the turbulence produced by the next prior constriction has disappeared. The constrictions may also be graded so as to produce greater degrees of turbulence in the direction of the flow of the cooling fluid.

Title: Improvements in or relating to tape-applying machines
IPC: A41D27/24
Filed: 1936-12-31
Abstract: 488,106. Taping-machines; tape-feeding apparatus. BRITISH UNITED SHOE MACHINERY CO., Ltd., and PRATT, J. W. Dec. 31, 1936, No. 35791/36 and 17553/37. [Class 73] [Also in Group XVI] A machine for applying adhesive tape to seams, more particularly the seams of rain coats, comprises pulling-off means for supplying the tape from a roll to an adhesive-applying device and further pull-off means for supplying the coated tape to an applying device which includes a roller with a resilient tyre and a domed work support through a slot in which the roller projects. The machine is of the character described in Specification 404,647, and the tape, which has a rubber coating on one side and a film of rubber solution on the other, is fed from a roll 23, Fig. 1, by means of the first pull-off device which comprises a roller 39 operated by a ratchet, and a roller 61 mounted on a cranked member 63 having at its other end a roller 67 against which the tape presses. When the tape is under tension the roller 61 is pressed into engagement with the roller 39 to effect the feed of the tape ; as the tension is released the pressure of the roll 61 diminishes and the feed temporarily ceases. The tape passes an orifice 29 in a vessel 33 for the adhesive, being pressed into contact by a spring-influenced member 35, and thence to the second pull-off device which consists of a roller 103 fed by a ratchet 107 and pawl 109 ; the latter is operated by a cranked lever 117, against the influence of a spring 115, the lever 117 carrying a roller 119 over which the tape passes. Tension moves the lever clockwise and renders the pawl operative. The tape then passes over a roller 77, Fig. 3, to a guide 87 carried by a swivelling stem 85 in a pivoted member 83. The roller spindle is mounted in slots 80 and the member 83 is connected by a link 89 with a pin 91 riding in slots 93. The roll 3, having a rubber tyre of the width of the tape, is surrounded by a work support 125. Specification 292,652, [Class 73], also is referred to.

Title: Nuclear reactor having control-rod retaining means
IPC: G21C7/14
Filed: 1972-08-01
Abstract: 1361698 Controlling reactors WESTING- HOUSE ELECTRIC CORP 1 Aug 1972 [13 Sept 1971] 35872/72 Heading G6C A nuclear reactor control rod mechanism includes pivoted magnetic levers 4 movable between a holding position in which they are capable of engaging a control rod drive shaft 10 and a release position in which the levers are displaced from the drive shaft, and permanent magnets 22 movable between a first position (right-hand side of the Fig.) in which they lie in a magnetic circuit including parts of the levers so as to provide a magnetic face to retain the levers in their holding position and a second position (left-hand side of the Fig.) in which they permit the levers to assume their release position. The levers 4 are pivoted about pins 5 to a bushing 6 slidable in a tube 1. A spring 14 biases the lower ends of the levers into engagement with a groove 9 at the head of drive shaft 10. The force exerted by the spring is insufficient to hold the shaft 10 against the action of gravity thereon, the shaft 10 being held up normally by means of an electromagnetic gripper mechanism (not shown). With the magnets 22 in their lower (second) position, they are shunted by enclosing tubes 21, so that the levers are able to release the shaft 10 should the gripper mechanism become de-energized. However, with the magnets 22 in their upper (first position) they co-operate with magnetic members 20 in the wall of tube 1 to provide a magnetic path (allowed) which acts on the levers to retain them in their holding position.  The magnets 22 are normally urged to their lower position by means of thrust exerted downwardly by members 37 which are secured to a missile shield. When, for refuelling, the shield and members 37 are raised, the magnets 22 move to thier upper position under the action of springs 31. The slidable mounting of bushing 6, and an arrangement of Bellville washers 43, enables the bushing 6 and levers 4 to accept any shock which might occur should the gripper mechanism be de-energized while the levers 4 are retained in their holding position. In a modification (Figs. 7-9, not shown), the magnetic members 20 are replaced by annular members (52) to eliminate necessary alignment procedures. Coils 13 are provided to determine the positions of the control rod. To permit replacement of coils 13, their support tube 48 can be detached from a tube 18 supporting the magnet arrangement by virtue of the provision of a bayonet connection comprising co-operable pins and slots.

Abstract: 1,093,687. Magnetic switches. PATWIN Inc. Aug. 10, 1966, No. 35875/66. Heading H2B. [Also in Division G4] Selective energization of windings 10 carried by the polepieces of a magnetic core 8 causes a permanent magnet salient pole rotor 24 to be aligned with the field induced in the core, and a permanent bar magnet 27, movable with the rotor, to actuate one of a circular array of sealed magnetic reed contact units. The contact units are mounted in tubes 12 on an annular printed circuit board which is electrically connected to a plug-in printed circuit connector 3 which also carries terminals for windings 10. The rotor 24 forms the hub of a numbered drum 22 which is visible through an aperture in a magnetically-shielding casing. The bar magnet 27 is carried on the inside of the drum. To prevent any of the circuits in which the contact units are inserted from being energized before the rotor has assumed its rest position, a triode is provided in the circuit and is reverse biased when any winding is energized. After the actuating current has been interrupted the rotor remains aligned with the pole to which it was last turned by virtue of its own magnetism.

As shown in Fig. 4, a roof is supported by a number of ordinary chock-pieces 8 and one or more collapsable chock-pieces which, according to one construction, comprise a body portion 1, Fig. 1, and a wedge member 7. The latter is normally held in position on the face 2 of the portion 1 by a pivoted catch 4 and is prevented from lateral movement by a lug 2b which engages in a slot therein. The chock-pieces above and below are located by ridges 7b, 3a and 2a, 3b, respectively. To collapse the structure, the catch 4 is knocked upwards whereupon the wedge member 7 slides down the face 2 and thus releases the chock-pieces normally supported thereon. A wedge member 7 and a catch 4 may be provided at each end of the chock-piece, the catches being pivoted about a common pin or separate pins. In a modification, the body portion of a double-ended chock-piece is built up of two end pieces connected by bars which are suitably connected by bolts and distance-pieces. In a further modification, Figs. 9 .. 11 (not shown), the wedge members of a double-ended chock-piece are supported by a single catch so pivoted as to release both of said members when operated. According to another form of double-ended chockpieces the catches may be comprised in a single rod passing through the length of the block, and having turned-down portions at each end which engage with the outsides of the wedge members. The upper faces of the blocks may be provided with vertically extending transverse webs for deflecting any falling objects when the structure is collapsed.
