Patent GB-981417-A (GB)
Title: Process for improving the mechanical properties of homopolymers or copolymers of monomers containing more than one double bond
IPC: C08F8/00
Filed: 1961-02-14
Abstract: The degree of unsaturation present in homo- and co-polymers of hydrocarbon monomers containing more than one double bond is decreased by subjecting the polymer, in the absence of any monomer, to the action of an "active Ziegler catalyst."  The action is preferably effected in a hydrocarbon or halogenated hydrocarbon solvent or diluent, at a temperature greater than 60 DEG C. for more than 2 minutes. By "Ziegler catalyst" is meant a catalyst formed by mixing at least one compound of a metal belonging to Group IV to VIII of the Mendel<\>aeff Periodic Table with a metal, alloy, hydride, or organometallic compound of a metal of Group I to III.  By "active Ziegler catalyst" is meant a catalyst which in the presence of a monomer causes a rise in temperature under adiabatic conditions.  The polymers treated may be made by any process e.g. with Ziegler catalysts, metal oxides, or peroxides.  The polymers treated may be mixtures, e.g. a mix of polybutadiene and an ethylene-propylene co-polymer. The polymers treated may be polybutadiene, polyisoprene, a copolymer of ethylene and propadiene, a copolymer of ethylene and hexadiene 1-5, or a copolymer of ethylene and butadiene. Specification 969,967 is referred to.

Patent GB-372848-A (GB)
Title: A method of drawing tubing particularly applicable to silica glass
IPC: C03B17/04
Filed: 1931-02-23
Abstract: 372,848. Making silica tubing. QUARTZ ET SILICE, 8, Rue d'Anjou, Paris. Feb. 23, 1931, No. 5617. Convention date, March 28, 1930. [Class 56.] A method of drawing tubing from material which has been rendered plastic by heat or by other physical agency, particularly fused silica, consists in providing a container or crucible with a die for shaping the tubing, a mandrel so arranged that it can be moved longitudinally through the material in the crucible and become centred in relation to the die, and means .for locking the mandrel in the desired position within the crucible. The crucible 1 is lagged with heat-resisting material la and is heated bv any suitable means. Its lower end is constricted and is fitted with a ring 24, and a member 26 with an axial passage fits into the ring. The mandrel consists of a carbon tube 14 which is provided at its lower end with a collar 21 and a conical point 22. The collar 21 co-operates with the ring 24 to shape the tubing as it is drawn: The mandrel 14 is attached to the lower end of a tube 12 which has an enlargement 11 having a spherical lower end that seats in a spherical cavity in a member 8. The tube 12 also carries a weight 16 and, at its upper end, a pointer 15. Screws 30 enable the tube 12 to be locked in any desired position which can be indicated by the pointer 15 and an index pointer 20. The material to be drawn may be in the form of a tubular ingot or a solid block. In the first case, the ingot is placed in the furnace, the mandrel is passed through the hole in the ingot until it reaches the position shown, and the crucible is heated until the material melts. If the material is in the form of a solid block, the mandrel is lifted and the point 21 is allowed to rest on the block. As the material is softened by the heat, the weight 16 forces the mandrel through the material until the part 22 becomes centred in the aperture in the member 26. In both cases, after continued heating, the member 8 is screwed upwards until it is in contact with the member 11 and supports the mandrel within the crucible, and the mandrel is then locked in position by the screws 30. The member 26 is then removed, and the molten material flows downwards and is drawn out into a tube by suitable apparatus, such as that described in Specification 270,692, [Class 56, Glass]. Air passes through the hollow mandrel into the interior of the crucible by . way of a hole 31, and the draught thus caused prevents the interior of the drawn tube from being soiled by condensed vapours.

Abstract: 212,567. Siemens & Halske Akt.-Ges. March 6, 1923, [Convention date]. Linear-dimension gauges. - A difference in length is determined by deforming an elastic body by a mechanical force, and deducing the resultant movement of a. point in the body from the size of the forco and the elasticity constant of the body. Fig. 3 shows the application to a gauge in which two fixed anvils 3, 4 are carried by arms 2, 5. Adjacent to the arm 5 is an arm 6 the cross-section of which is such that under the same load it bends ninety-nine times as much a.s the arm 5. A vernier 9 on the arm 6 is arranged against a scale 7 on the arm 5. and a screw 10 is provided to force the arms apart to secure fine adjustment of the anvil 4. The movement of the anvil will be one-hundredth of the movement indicated on the scale 7. The movement which takes place in an elastic body when subjected to a mechanical stress is used to feed the work-table of a dividing-engine. In the arrangement shown in Figs. 4 and 6, the elastic body consists of two rods 11 the outer ends of which are secured in fixed brackets 12, the inner ends being connected by a bridge piece 15. To the bridge piece are attached cables 22 carrying weights 23 which apply the load when their supporting plungers 24 are lowered. The work plate 19 is clamped to a steel cylinder 25 which may be clamped to the bridge piece 15 or alternatively to fixed brackets 20. The brackets and bridge piece are formed like divided bearings, the upper halves of which are supported by springs 16, and may be forced down to effect clamping by compressed air admitted to cushions 21. In use, the cylinder 25 is clamped to the bridge piece 15 while the load is being applied, and the movement of the ends of the rods 11 is imparted to the work-table 19. During the return movement of the rods while the load is being relieved, the cylinder is released from the bridge piece and clamped to the brackets 20. An automatic device may be provided for controlling the clamps &c. The chamber 13 is filled with oil, and the cylinder 25 is secured by plates 17 to floats 18 which are so dimensioned as to be just able to support the weight of all the parts moving therewith.

Abstract: 764,388. Accelerometers. BENDIX AVIATION CORPORATION. Feb. 28, 1955 [March 8, 1954], No. 5899/55. Class 106 (3). An accelerometer comprises a mass 14 suspended elastically, e.g. by springs 15, 16 in a frame 12, 13, 62, the oscillations of the mass being damped by two relatively slidable parts, one secured to the frame and the other to the mass, which define a variable-volume air chamber. As shown, the part secured to the frame comprises a piston 26 and the part secured to the mass is a cylinder 37 preferably arranged within the hollow centre of the mass so that the piston and cylinder also serve toguide the mass in its oscillation. The mass is prevented from rotation relative to the frame by a roller 61 mounted for free rotation on the mass and running on a track 63 in the frame member 62. The air confined in the chamber between the bottom face of the piston and the opposing cylinder wall is allowed to leak via an aperture whose dimensions are regulated by an adjusting screw. Movement of the mass 14 is communicated to a lever arm 58 by means of a stud 59 secured to the mass on a ball-bearing 57 and thence to an indicating pointer. The meter is enclosed in a sealed casing.

Filed: 1940-04-03
Abstract: 535,514. Sewing-machines. FAIRWEATHER, W. C. (Singer Manufacturing Co. April 3, 1940, No. 5958. [Class 112] An arm 40 carrying a ruffling blade 42 is secured upon a shaft 37 linked by a crank-arm 34 and link 33 to a block which is reciprocated by an eccentric rod 16 in an arcuate slot 19 in a lever 20. Then the lever 20 is moved clockwise into a position determined by a stop, the slot 19 is concentric with the pin of the crank arm 34 and the ruffler is not reciprocated. Movement of the lever 20 to this position is used by two means to remove the ruffling blade from the neighbourhood of the needle. The extension 56 of the lever 20, which actually overlies a part 54 of a lever 53, depresses that part and through the linkage 52, 51 causes a part 48 to be depressed. This part lies above a pin 46, normally pressed upwards by a spring, and through the pin depresses the heel of the pivoted blade carrier 41 and lifts the ruffler blade. Also a pin 60 on a part 61 secured to the extension 56 which enters a cam-slot 59 in an arm 58 rotates that arm and, with it, a bush 38 in which the ruffler shaft 37 is eccentrically mounted. This movement shifts the shaft 37 bodily in an approximately horizontal direction and moves the ruffler blade away from the needle. During ruffling operations, the pin 60 rides in a portion of the cam slot 59 which is then concentric with the shaft 21 so that ,movements of the lever 20 to vary the stroke of the ruffling blade do not actuate the part 48 or the bush 38. The lever 20 is spring urged in a clockwise direction and is moved against the spring by a treadle-operated connection.

Filed: 1936-02-29
Abstract: 471,193. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 29, 1936, No. 6195. Convention date, March 2, 1935. [Class 40 (iv)] [Also in Group XL] Discharge-tube apparatus with a controllable ray, for example, a cathode-ray tube, is used as selecting and connecting apparatus in an electric signalling system, for example, as a finder or selector in an automatic telephone exchange. In the cathode-ray tube, Fig. 1, connection between a sender S and one of a plurality of receivers M1 ... M4 is effected by applying suitable potentials to plates SP thereby causing the ray to strike a corresponding terminal member at the end of the tube. Two tubes acting respectively as a finder and connector may be arranged with their cathodes connected together and in a modification two rays acting respectively as finder and connector may be provided in a single tube with a single field of contacts. In a two-wire connection, a tube must be included in each wire and a section containing such tubes may be connected to the lines at each end through transformers having their mid-points connected together. In the tube, Fig. 5, comprising evacuated and gas-filled chambers separated by a screen V, the cathode-ray acts temporarily through one of a series of windows F to cause a dischargeconnection to be established between perforated plates or grids SN1, SN2 connected to the two conductors of a link-circuit and contacts E1, E2 connected to a subscriber's line. The grids and contacts may be replaced by horizontal and vertical strips, respectively, by which connections may be established or required between six subscribers' lines and six linkcircuits. In the tube K, Fig. 8, the cathoderay controls pairs of grids in a hot-cathode gas-filled discharge tube TY whereby dischargeconnections are established through the tube TY between any two subgcribers A1 ... A4. Control of the potential on plates SP by received impulses is effected by charging a condenser C1 over contact 1 at the beginning of each digit and transferring a portion of its charge to a smaller condenser G2 at each operation of impulse contacts 2. The stream of secondary electrons produced by the striking of a cathode-ray against one of the terminal members at the end of the tube may be employed as the connecting circuit. The cathoderay tube may be provided with a control grid and such a tube with one line connected to the grid and cathode and the other to the anode and cathode acts as a one-way amplifier. The Specification as open to inspection under Sect. 91 comprises also constructions of discharge-tube selectors forming the subjectmatter of Specification 471,194. This does not appear in the Specification as accepted.

Abstract: 151,533. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). March 1, 1920. Controllers, actuating mechanism for.-A controller is so constructed that during a certain predetermined range of the motor it can be moved into forward or reverse position, but that outside that range it can be operated in one direction only. The movable contact members 1, 2 are fixed to the shaft 3 which also carries a member 4 which rotates with the shaft but can slide axially upon it. A member 5 is rotatably mounted on the shaft and carries two spring-connected pawls 6, 7 which engage two projections 10, 11 on the member 4. The member 4 is moved axially by an oscillating arm 8 driven by the controlled machine. The pawl 7 has a notch 12 at one end of the range of movement and the pawl 6 has a notch at the other end. Within the limits formed by the notches, rotation of the member 5 in one direction or the other will operate the controller contacts 1, 2 to the forward or reverse position, but when one of the notches is reached, the member 4 is returned to its intermediate position by means of the spring-controlled lever 13 and then the controller can only be operated to the position for the return of the motor. The roller 23 on the lever 22 enters notches in the periphery of the member 5 to hold it.in its various positions. The supports for the contact fingers are secured by bolts 52 to a bracket 53 secured to the front wall of the casing.
