Title: Method and apparatus for the bulk polymerisation of organic ethylenically-unsaturated monomers
IPC: C08F2/00
Filed: 1962-06-08
Abstract: An organic ethylenically unsaturated monomer which polymerizes exothermally is polymerized in an exothermal stage followed by a heating stage to cause polymerization of unpolymerized monomer and the polymeric product in molten form is subjected to sufficient vacuum to remove unreacted monomer.  The monomer may be styrene, a chlorostyrene, a vinyl toluene, vinyl acetate, methyl methacrylate, acrylonitrile or vinyl pyrrolidone. The vapour space above the polymerizing material may be confined and during the exothermal stage the temperature of the vapour space may be cooled by indirect heat exchange <PICT:1013426/C3/1> <PICT:1013426/C3/2> to a temperature low enough to condense monomer vapour.  A polymerization apparatus is described with reference to Figs. 1-11 (Figs. 2-10 not shown).

Abstract: 1359242 Controlling aircraft SOC NATIONALE INDUSTRIELLE AEROSPATIALE 12 May 1972 [18 May 1971] 22375/72 Heading B7G [Also in Division H1] An aircraft control system comprises a pilot actuated member A which operates through a control run C1, C2 to operate a control surface B, there being a servomotor F, which when inactive forms part of the control run or when activated under the control of an autopilot or a stabilizer unit P is anchored by a relay unit D to enable surface B to be moved by the servomotor independently of movement by control member A. The unit D comprises a housing 11 and an end plate 12 having bearings 3a, 3b for a shaft 3 on which a lever E is fixed, the lever being connected also to the control rod C 1 . A lever 5 having a finger 5a is fixed to shaft 3 and a further finger 10a is extended from a gear sector 10 freely mounted on shaft 3. Also freely mounted on shaft 3 are collars 6, 7 formed respectively with plate-like fingers 6a, 7a which span fingers 5a, 10a on opposite sides thereof and are urged into engagement therewith by a torsion spring 4 connecting collars 6 and 7. Adjustable electrical contacts 14, 26 are mounted on fingers 7a (by way of an extension bracket) and finger 6a respectively and wired to the automatic control unit P so that servomotor F is operative when the contacts are in engagement and inoperative when they are separated. The gear sector 10 meshes with a pinion 2 on a shaft 15 which carries also a brake disc 9 running between brake pads 29, 30, the latter being actuable by a solenoid actuator 1 against an application spring. Under automatic control the solenoid 1 is deenergized and the brake locked thus, within the pre-loading limit set by spring 4, locking lever E against movement to provide an anchorage for the servomotor F. Under manual control the solenoid 1 is energized to free the brake, the pilot operates member A which through lever E overcomes spring 4 and separates contacts 14, 26 thereby de-activating the automatic control unit P and servomotor F. A motor drive unit (16-18, Fig. 4, not shown) may be connected to one end of shaft 15 to enable the pilot to bias or trim the control surface and a position indicator for feeding information to the automatic control unit may be connected to the other end of shaft 15.

Title: Nail puller
IPC: B25C11/02
Filed: 1921-08-26
Abstract: 188,114. Schrem, A. Aug. 26, 1921. Nail extractors.-A nail extractor comprises a pair of pivotally connected pincer jaws mounted to slide in guides in a box-like frame and pivoted to a pair of hand levers, which, when moved away from each other first close the pincers on the nail and then by engaging curved bearing surfaces on the frame move the pincers bodily along the guides to extract the nail. A box-like frame 2, provided with feet 4 to engage the article from which the nail 16 is to be removed has slots 7 in two opposite walls 6 to receive and guide the pivot 8 of the pincer jaws 1 and the pivot 9 of a pair of links 15 which with the hand levers 3 are connected by pivots 13 to the arms 14 of the pincers. The hand levers 3 engage curved bearing surfaces 12 on the frame 2 and pass through slots 5. The edges of the walls 6 are bent inwards to form flanges 10 for guiding the arms 14 and the lower parts 11 of these flanges form abutment surfaces for the inclined ends of the arms 14 when the pincers are open. In operation, as the arms 3 are spread apart the jaws are pressed downwards into the wood by the action of the flanges 11 on the arms 14 and then closed upon the nail the arms 3 in continuing to turn on the surfaces 12 causing the pincers to rise vertically. To enable the pincers to be readily removed from the frame the lower parts of the walls 6 may be bent outwardly as shown in broken lines in Fig. 4. Strengthening plates 17, Figs. 3, 4 may bridge the slots 7.

Title: Uncoupler devices for railway vehicles
IPC: H01F7/02
Filed: 1962-06-14
Abstract: 977,855. Railway vehicle uncoupling devices. STAMICARBON N.V. June 14, 1962 [June 15, 1961], No. 22960/62. Addition to 926,439. Heading B7T. The magnet carrying pivotable arm of the parent Specification is modified by the provision of a wedge-shaped part 9, Figs. 1, 2, which prevents the arm from being accidentally retained in the swung down position, and by the provision of pivoted cheeks 10a, 10b, Fig. 3, which are pushed inwardly when the vehicles are moved closer together to slacken the couplings for uncoupling. In operation, the arm 5 in an upwardly-pivoted position runs its wheel 6 along the side of one of the coupled vehicles until the gap between the vehicles is reached. The arm 5 then falls down between the vehicles which are maintained at the maximum distance apart permitted by the couplings, and engages its magnet shoe 7 with the hook 3a. The vehicles are then brought closer together as in Fig. 3, so that the cheeks 10a, 10b whose maximum width is nearly equal to the distance between the buffers 2a, 2b in Fig. 2, are then forced inwardly against the action of a spring, Fig. 4 (not shown), thus ensuring that the shoe 7 does not accidentally engage the hook 3b instead of the hook 3a. The spring acting on the cheeks is so strong, that when the support to which the arm 5 is attached is taken along by the vehicles, as in the parent Specification, the cheeks will not be moved together by the force of such translation but will only be depressed by the stronger force exerted by the vehicles moving together as in Fig. 3. When the coupling becomes slack, as in Fig. 3, the hook 3a clings to the magnet but rolls in contact with the shoe 7 so that the link 4b drops. Uncoupling is then completed by raising the arm 5.

Filed: 1954-08-06
Abstract: A tobacco smoke filter is formed from a urea formaldehyde foam which, after preparation, is treated with aqueous urea to eliminate the formalin odour and is compressed or subjected to high frequency vibrations to rupture the walls of some of the cells in the foam in order to permit the smoke to flow therethrough.  The foam may be strengthened by the addition thereto during the foaming process of fibrous materials, adhesives, varnishes, resins or glues, particularly phenol, cresol and carbamide resins, cellulose resins or acetates, and formaldehyde resins.  Hygroscopic substances such as glycerin or silicones may also be added and the filtering effect on nicotine may be increased by the addition of iron chloride.ALSO:A tobacco smoke filter is formed from a urea formaldehyde foam which, after preparation, is treated with aqueous urea to eliminate the formalin odour and is compressed or subjected to high frequency vibrations to cause the cavities in the foam to communicate with one another in order to permit the flow of tobacco smoke therethrough. The foam may be spread on a carrier of crepe paper and divided into strips which are rolled up to form a filter plug which is incorporated in a cigarette tube. Alternatively filter rods may be cut out of a compressed slab of the foam by suitably grooved rollers, which rods may be passed through heated nozzles to provide a surface skin to prevent the compressed foam expanding, or wrapped in paper. The foam may be strengthened by the addition thereto during the foaming process of fibrous materials, adhesives, varnishes, resins, or glues and a predetermined humidity may be maintained in the filter by the addition thereto of hygroscopic substances such as glycerin or silicones, which latter only reveal a hygroscopic action when the tobacco smoke flows through the filter.  Iron chloride may be added to the foam to increase the filtering effect on nicotine.

Abstract: 796,535. Spinning &c. machine driving arrangements. HAMEL, E. July 30,1956 [July 30, 1955], No. 23396/56. Class 120(2) In a spinning or twisting machine wherein the spindles and delivery and drafting mechanisms are driven from a common reversible electric motor, a reversing gear interposed in the drive to the delivery &c. mechanism is so disposed that when it is moved from one position to the other it operates a switch controlling motor reversal; thus, change of direction of direction of rotation of the spindles synchronises with operation of the reversing gear and the direction of rotation of the delivery &c. mechanism remains unchanged. In one embodiment, the motor drives tin rollers 4 and spindle wharves 6 via a main shaft 1, gears 2, 3 and a belt 5. Gears 14, operating the delivery mechanism on each side of a double-sided machine, are driven from gear 2 through gear trains via a reversing gear 9 on a pivoted arm 10. In the position shown, arm 10 holds an arm 20 so that an extension 22 closes a motor-reversing switch 24. Arm 10 can be moved to the right so that gear 8 moves from engagement with a gear 15 into engagement with a gear 11, thereby reversing the drive to gears 14; at the same time, arm 10 enters a recess 26 in arm 20 which swings back to open switch 24 and reverse the motor, the direction of rotation of gears 14 thus remaining the same.
