Filed: 1962-02-23
Abstract: 941,102. Type-bar-making machines. MERGENTHALER LINOTYPE CO. Feb. 23, 1962 [Feb. 23, 1961], No. 7087/62. Heading B6W.  Distributing matrices.-The distributer shifter slide is biased by resilient means to matrix delivery position and is held in matrix receiving position by latching means which it engages, until said latching means is released by the second elevator seating in its upper position. The distributer shifter slide 11, Figs. 1B and 6, comprises a pusher member 13 urged outwardly by a spring 20, and is moved to the right to matrix receiving position, when a clutch 27 is energized on closing of a camcontrolled switch, by a cable 22, Figs. 1A, 1B and 6, carried on pulleys 24, 25, 30, one end of the cable being positively, and the other end resiliently by a spring 31, secured to the slide 11. In receiving position, the slide actuates a switch 40 to de-energize the clutch 27, and is held by a spring-urged latch 43. When the elevator bar 15 reaches its matrix delivery position, it pushes back the latch and a spring 32 moves the slide 11 to its delivery position, the motion being modified by a clamping device 51. When the slide starts to move to receiving position, it allows a switch 34 to close, energizing a clutch 55 to rotate the distributer screws. After the slide returns to delivery position and opens the switch 34, the screws continue to rotate until the last matrix is delivered, owing to a clutch holding circuit through a matrix and the distributer bar 54. Jammed matrices cause one of the screws to move axially and open a switch 76 to stop the screws rotating. The switch 76 is also opened if the receiving channel 77 is not in position.

Title: Polyesters
IPC: C08G63/682
Filed: 1965-02-19
Abstract: Chlorinated polyesters of at least one dicarboxylic acid and at least one dihydric alcohol, containing at least 5 wt. per cent of chlorine, at least 50% of the chlorination taking place on -CH2-groups, may be prepared by contacting the corresponding unchlorinated ester in solution or suspension with a chlorinating agent i.p.o. a chlorination promoter.  Suitable polyesters for chlorination are those derived from 1:2-, 1:3- or 1:4-cyclohexanedimethanol and aromatic acids, e.g. o-, m- and p-phthalic acids, 1:5- and 2:6-naphthalene-, 3:31- and 4:41-diphenyl-, and 4:41-diphenyl ether-, 4:41-diphenylsulphone and 4:41-diphenyl sulphide dicarboxylic acids. Chlorine is the preferred chlorinating agent, but SO2Cl2, PCl5 and t.-BuOC may be used. The promoter is U.V. or visible radiation or a free radical catalyst, e.g. t.-butyl peroxypivalate, diisopropyl peroxydicarbonate, acetyl peroxide or azobisisobutyronitrile. Suitable reaction solvents are tetra- or penta-chloroethane, preferably containing 5-50 wt. per cent of a trihalo acetic acid. Water and CaCO3 may be added to neutralize HCl, unless a trihalo acid is present. The products are soluble in CH2Cl2, CHCl3 and dioxan and these solutions may be used as dopes in preparing films and fibres, and for moulding to shaped articles; they may be heat-stabilized by adding 0.1-4% of, e.g., an organo-tin-sulphur, organo-tin, epoxy, aziridinyl or urea-phosphite type, or an unsaturated fatty acid Cd, Zn or Sn salt or CaCO3.  In Examples the substrate polyester is derived from terephthalic/isophthalic acid, isophthalic/2:6-naphthalene dicarboxylic acid or dibenzoic/ phthalic acid mixtures or from isophthalic, terephthalic, oxydibenzoic, thiodibenzoic, 1:4-cyclohexane dicarboxylic or sebacic acid and ethylene, tetramethylene, hexamethylene, decamethylene, neopentyl glycols, or 2:2:4-trimethylpentane - 1:3 - diol, cyclohexane - 1:4-diol or cyclohexane-1:4-dimethanol; chlorination is by Cl2 under U.V. irradiation or i.p.o. diisopropyl peroxydicarbonate or azobisisobutyronitrile, the polyester being either in tetrachloroethane solution, over CaCO3 in some cases, when NaHCO3 is added after the chlorination, or in CHCl3/CF3COOH or C2H4Cl2/CF3COOH or C2H2Cl4/CF3COOH.  Films are cast from CH2Cl2 solution, and in Example 14 a fibre is spun from CH2Cl2 solution into ethanol.ALSO:Surfaces may be coated with a chlorinated polyester derived from a dicarboxylic acid and a diol and containing at least 5% by weight of chlorine and in which at least 50% of the chlorination has taken place on -CH2-groups.  In Example 10 a chlorinated poly-tetramethylene isophthalate, soluble in CH2Cl2, is cast onto glass or metal.

Filed: 1931-03-09
Abstract: 384,982. Valve amplifying circuits. MODRACH, A., 36, Cerska Ulica, Belgrade. March 9, 1931, No. 7303. Convention date, March 13, 1930. Void [Published under Sect. 91 of the Acts]. [Class 40 (v).] Railway trains are provided with apparatus for transmitting to and receiving from the rails electromagnetic oscillations whereby braking and warning signals are given when two trains approach too closely. The transmitter, Fig. 13, comprises two thermionic valves S1, S2 the anodes of which are connected through the coil t, which couples the apparatus to the rails, with an oscillatory circuit L1, C1 which is coupled by the inductance L2 with the grid circuits. A buzzer device M and transformer T with associated condensers C2, C3 modulates the transmission. With the arrangement shown in Fig. 17, failure of the apparatus or departure from normal conditions gives warning signals and shuts off the train power. The transmission apparatus O is coupled by an oscillatory circuit 98, 99 to a thermionic valve 101 acting as a rectifier to supply a magnet 106 ; failure of the transmitter causes the magnet to release its armature which closes contact springs 109, 110 whereby lamp and bell signals 115, 116 are actuated and a magnet 115<1> is energized to depress a screw-threaded rod 117 into driving engagement with a clutch disc on a spindle driven from the vehicle wheel so that a nut 67 is displaced to open a slide valve 120 whereby pressure air is admitted to depress a piston 128 and so to shut down the steam throttle lever 129. A minimum cut-out relav 134 is included in the receiver relay circuit and is adjusted for the current at the maximum range of two stations. If the received current is less than this minimum the cut-out relay 134 drops its armature to close contact springs 136, 137 which give warning signals and shut off the power as before.

IPC: F03C1/04
Filed: 1968-02-15
Abstract: 1,210,868. Hydraulic reciprocating motors. HIAB-FOCO A. B. Feb.15, 1968, No.7353/68. Heading F1A. A hydraulic motor comprises an inner ring 22 and an outer ring 21 one of which, 21 as shown, is formed with a cam track 17, and the other carries spring-loaded working pistons 10, 11 and 12, and slide valves 13, 14, 15 controlling liquid supply and discharge to and from their corresponding pistons, the pistons and slide valves acting through rollers 20, 16 on the cam track. Inner ring 22 runs on a ball race within outer ring 21. The angle between each piston and its corresponding slide valve is such that, when the piston is traversing the top of a crest or bottom of a trough of the cam track, the slide valve is in an overlap position shutting off the supply and discharge connections to the piston. In a multi-speed embodiment, groups of two slide valves in parallel control groups of three pistons, one slide valve controlling one piston and the other controlling two pistons. The first speed is obtained with all the pistons in operation. The second speed, 1.5 times the first speed, is obtained by moving the slide valves controlling one piston radically inwardly by servo-pressure so as not to be operated by the cam track, and to render their associated pistons inoperative. The third speed, 3 times the first, is obtained by moving the slide valves controlling two pistons out of registration with the cam track, to render their associated pistons inoperative. The slide valves may be in two parts, one carrying the cam follower, and the other being biased by the servo-pressure into its inoperative position. In another embodiment, Figs. 5 to 7 (not shown), each slide valve controls three working pistons on corresponding parts of the cam track, the inner ring 22 being formed in two interfitting parts, Fig.7 (not shown), to facilitate the formation of distributing channels and the location of pressure relief valves. The supply and discharge connections may be reversed to provide reverse rotation of the motor.

Title: Method and machine for dynamic balancing
IPC: G01M1/30
Filed: 1976-02-25
Abstract: 1495913 Balancing apparatus; shafts AVERY DENISON Ltd 25 Feb 1976 [3 Oct 1975] 07376/76 Heading F2U A method of dynamically balancing a composite workpiece 6 having two parts joined together by a longitudinally-movable splined coupling 6d, e.g. an articulated drive shaft, includes means for providing a relative torque acting about the rotation axis and causing the two parts to be braced against each other, while the workpiece assembly is driven in rotation. The relative torque may be produced by applying to one end of the workpiece a brake which may consist of an eddy-current brake or an electrical generator (10) feeding an adjustable load, Fig. 1 (not shown). Alternatively, the relative torque may be preset by the adjustment of a worm device 15, 16, Fig. 2, interposed between a drive input shaft, driven by motor 7, and a secondary shaft 13, these two shafts being coupled by toothed belts 11, 12 to the two ends of the workpiece, which includes an axially-movable splined coupling 6d. Since a splined coupling is constructed with sliding clearances between its members, these clearances may also permit some radial excursions of fluctuating extent and orientation, under the action of centrifugal forces, this effect being termed "vagabond-unbalance", and the effectiveness of operation of a balancing machine might thereby be impaired. By the application of a relative torque between the splined coupling members, during rotation in a balancing apparatus, the spline faces are held in contact and vagabond-unbalance effects are minimized.
