Title: Improvements in centrifugal pendulum vibration dampers
IPC: F16F15/14
Filed: 1949-07-11
Abstract: 666,657. Torsional vibration-dampers. SARAZIN, G. F. July 11, 1949, No. 18305/49. Class 108(iii). In a torsional vibrationdamper comprising pendular masses eccentrically suspended to supports on a rotating member, about axes parallel to the axis of rotation thereof, each mass being connected with the corresponding support through rings perpendicular to the axis and each having its internal surface in rolling contact with convex curved surfaces respectively carried by the mass and the support, the mass and the support are provided, in their respective surfaces facing each other, with corresponding sets of recesses, the respective recesses of the sets being located opposite one another, so that every two corresponding recesses of the mass and support respectively accommodate one of the rings, the recesses of each set being in line and separated from one another by partitions transverse to the axis and through which extends a rod parallel to the axis and which carries, in the recesses, the curved convex surface on which the internal surface of the corresponding ring bears. In the arrangement shown, a pendular mass element 2 and a support element 3, which is rigidly secured to a rotatable shaft 1, each comprises a series of plates 2a and 3a respectively, which may be of sheet metal. Alternate plates of the element 2 and the support 3 are provided with notches 2b and 3b respectively which, when the damper is assembled, form recesses 5 which house rings 7. The latter are supported on convex surfaces 6a of rods 6 which pass through and are carried by the plates 2a and 3a. Radial displacement of the notched plates is prevented by tie bolts 8 and rivets 8a respectively. The damper which is preferably housed in a casing 9, is lubricated by means of graphite powder contained in granular form in chambers 11 formed at the base of the support 3 by spaces between notched and unnotched plates and a closure plate 10. The graphite infiltrates, during operation of the damper, through interstices provided between the plates. When the damper is used within an engine casing, lubrication is effected by the oil mist in the engine casing. In a modification, the notched plates 3a are made of non-metallic material such as compressed fibre and project, at at least one point, above the unnotched plates in order to reduce noise in operation. In another modification, Fig. 3 (not shown), each of the rings 7 is provided with surfaces which co-operate with adjacent portions of the rod to prevent rotation of the ring during operation of the damper.

Title: Improvements in or relating to ionization chambers
IPC: H01J47/02
Filed: 1958-06-12
Abstract: 848,145. Ionization chambers. LANDIS & GYR A. G June 12, 1958 [June 14, 1957], No. 18878/58. Class 39(1). An electrical circuit includes a controllable ionization chamber having a collector electrode, an opposing electrode and a control electrode the circuit being such that an electric potential is established between the collector and opposing electrodes and that a variable electric potential is applied simultnaeously to the control electrode, the opposing and control electrodes both being in the form of imperforate plates and being located symmetrically with respect to the collector electrode. In one form, Fig. 1, an opposing electrode 1 connected to a terminal 21 and a control electrode 2 connected to a terminal 22 are located opposite a collector electrode 10 connected to a terminal 20, each pair of electrodes subtending an angle of 60 degrees. Terminal 21 is connected to a potential + Uk and terminal 22 is connected to the slider 25 of a potentiometer 23 connected between potentials + Uk and -Uk and having a fixed centre tap connected to ground at 24. The potential of the control electrode 10 can thus be varied from +Uk to -U k , and when the chamber is irradiated a controllable ionization current Ii flows from the electrode 10 to ground through a load resistance 26. The electrodes 1 and 2 may alternatively be arranged side by side in a plane parallel to the collector electrode 10. This arrangement provides an unfavourable field distribution which may be improved by dividing the electrodes 1 and 2 into a number, e.g. three, of parts arranged alternately side by side. Fig. 4 shows such an arrangement, in which segments 1, 3 and 5 forming an opposing electrode are arranged alternately with segments 2, 4 and 6 forming a control electrode around a cylindrical collector electrode 10. The segments 1 to 6 may alternatively be in the form of flat plates. The Specification refers to a known controllable ionization chamber in which a control voltage is applied to a grid arranged between an opposing electrode and a collector electrode at a small spacing from the latter.

Patent GB-820154-A (GB)
Title: Copolymer compositions
IPC: C08L25/00
Filed: 1956-06-25
Abstract: A polymeric composition of (a) more than 50% by weight of a rigid water-insoluble copolymer of at least one monovinyl aromatic compound with another ethylenic monomer, the copolymer containing on the average 3 to 35 carboxyl groups per 100 monomer units in the polymer chain, and (b) less than 50% of a rubbery copolymer of a conjugated diene hydrocarbon of the general formula CH2=CH1-CH2=CHR3 where R1, R2 are hydrogen atoms or methyl or ethyl groups, and R3 is a hydrogen atom or a methyl group, and an ethylenic monomer, the copolymer containing an average of 1.5 to 18 carbonyl groups per 100 monomer units in the polymer chain and with a brittle point of 0 DEG  C. or lower.  The rigid copolymer may be prepared by copolymerizing a monovinyl aromatic compound such as styrene, vinyl toluene, a -methyl styrene, 2,5-dichlorostyrene and vinyl napthalene with an ethylenic mono- or polycarboxylic acid such as acrylic, methacrylic, crotonic, maleic, itaconic, fumaric, citraconic, or methylene malonic and optionally with a third monomer such as vinylidene chloride, methyl methacrylate, or a -methyl styrene by a solution method using a free-radical catalyst, e.g. potassium persulphate and emulsifier, a sodium salt of an alkylaryl polyether sulphonate, with t-dodecyl mercaptan and when maleic acid is used the acid is added at a rate slower than the rate of polymerization.  Alternatively, the aromatic compound may be copolymerized with ethylenic compounds containing groups such as ester, amide or nitrile which may subsequently be hydrolysed to the free carboxyl groups.  The rubbery copolymer is a copolymer of a conjugated 1,3-diene, e.g. butadiene, 1,3-pentadiene, isoprene, 2-ethyl butadiene, 2,3-dimethylbutadiene and a carboxyl containing monomer such as acrylic, methacrylic, crotonic, fumaric, methylene malonic, citraconic, or itaconic acids and preferably with a third monomer such as styrene, a -methyl styrene, an acrylate or methacrylate ester and divinyl benzene, and may be prepared as the rigid copolymer.  Alternatively, ethylenic monomers containing groups hydrolysable to carbonyl groups, e.g. ester, amide or nitriles, are introduced and hydrolysed, or the polymer may be reacted with a carboxylating agent such as thioglycollic acid under oxidizing conditions.  The compositions are prepared by mixing aqueous emulsions, or by blending on a rubber mill, or alternatively by dissolving the rubbery copolymer in a mixture of monomers used to prepare the rigid copolymer and subsequently polymerizing.  The drum-dried flake is extended and may be ground and compression moulded to give products with high impact strength, tensile strength and heat distortion temperature, and low deformation under load. U.S.A. Specification 2,662,874 is referred to.

Filed: 1922-07-18
Abstract: 210,100. Cook & Co., Manchester, Ltd., and Cook, J. W. July 18, 1922. Feeding carding-engines. - Cotton and other fibrous material is converted in a progressive and continuous manner, by a series of co-ordinated appliances, from the, compact matted condition resulting from baling into light fleecy sheets adapted to be passed direct to the feed rollers of a carding-engine, thereby dispensing with preparatory machines such as openers and scutchers. The material is fed from a bale breaker A to bins B, where it is mixed or blended by lattices B<1>, B<2>, and a spiked roller B<3>, and is then placed in hopper feeders C comprising oppositely moving lattices C<2>, C<3>, and beaters C<4>, C<5>. The product from the hopper feeders may be allowed to accumulate, and for this purpose is delivered by perforated rollers D, D' and rollers e, e<1>, E<1> E<2>, E<3>, Fig. 1, and formed into soft rolls R; or it may be delivered in its loose state through an outlet C<7>, Fig. 8. In the former case, the rolls R', R<2> are placed on a lattice f, and in the latter the material is delivered to a lattice P. From these lattices the material is fed to a pneumatic loosening-machine G of the kind described in Specification 122,342, which delivers it in light fleeces to a licker-in roller H provided with dividing plates, from which it is conveyed by trunks h<1>, h<2>, h<3> to pneumatic doubling and feeding machines J<1>, J<2>, J<3> similar to the machine G and delivered to the feed plates of carding-engines K<1>, K<2>, K<3>. The feed to the machine G is controlled by a piano-regulator comprising rollers F<2>, f<2>, Cone drum mechanism F<6>, and a differential gear. In the arrangement shown in Fig. 8, rollers Rare carried by levers r connected with links and levers r<3> controlling the. cone-belt mechanism. The shaft p of the lattice is driven from the shaft of the feed roller R', and the shaft C<9> of the hopper feeder is driven from the shaft p<1>. A flap i, Fig. 4, in the tube leading from the. licker-in H is normally maintained in the posi. tion shown in full lines by a detent M<5>, M<6> controlled by a solenoid M. If one. of the carding- engines is stopped the circuit of the solenoid is closed and the detent disengaged from a notch M<7> on a brake-band M<8>, which embraces a disc m<7> oscillated by a crank disc m<1>, whereupon the brake-band is moved by the disc until the detent engages a notch M<4>, and the flap moved into the position shown in dotted lines. The material delivered by the licker-in H is thereupon returned by the trunk h<11> to the bin until the carding-engine again starts and opens the circuit of the solenoid M. Impurities are removed from the material during its treatment through grids P beneath the beater C<5>, by the perforated rollers D, D', and through grids beneath the lickers-in C<1>, H and through the wire cages G<8> j<1>, j<2>, j<3> of the pneumatic loosening-machines. . ,
