Abstract: 1,156,083. Simultaneous adjustment of clutches at a plurality of winding stations. BARMAG BARMER MASCHINENFABRIK A.G. 23 Feb., 1967 [23 Feb., 1966], No. 8683/67. Heading DID. In a textile winding apparatus each winding station includes an eddy current clutch, one element of which is rotatably driven by a driving element while the other element is secured to and drives the spindle, the clearance between the two clutch elements 1, 2 at each station being simultaneously adjusted by an adjusting means acting on one element of each clutch to move that element axially of the spindle. A chain drive 35 driven by a handle 9 may be used to rotate at each station a gear ring 7 fixed to a ring 6 which is internally threaded to co-operate with the screw thread on a flange 8 of the spindle, rotation of ring 7 causing axial movement of ring 6. The drive element 4 bearing a clutch element 2 is rotatably mounted on ring 6 by means of ball bearings 5 and is axially movable with the ring 6. In modifications of this embodiment one or both of the gear ring 7 and the drive element 4 is or are axially unmovable, whilst the clutch element is axially displaceable on rotation of gear ring 7. Alternatively the element 2 forms an axially immovable unit with the drive element while the other clutch element 1 is axially displaceable on the spindle by means of an eccentric or lever system common to the several stations (Figs 5-7, not shown).

Title: Improvements in or relating to control circuits for electric relays
IPC: H02H7/22
Filed: 1959-03-16
Abstract: 882,300. Protective arrangements. WESTINGHOUSE ELECTRIC CORPORATION. March 16, 1959 [March 20, 1958], No. 8968/59. Class 38 (5). The cycling or hunting of a " latch type " relay 11, should a control switch 31 be held closed when the relay is tripped open, is prevented by a capacitor 22 connected in series with the closing coil 12 of the relay. In the alternator control circuit shown, the charging current through the capacitor 22 on closure of the switch 31 energizes the coil 12 sufficiently for the relay to close and be latched closed by a latch 13. The relay 11 opens contacts 19 to open the circuit of the coil 12 and closes contacts 20 to enable the capacitor to be fully charged. If, now, protective relays 26 close contacts 27, the latch is released by the coil 14 and the relay 11 opens. If the switch 31 has been held closed, the relay does not reclose automatically as the charged capacitor prevents further flow of current through the coil 12. On the release of the switch 31, the capacitor discharges through a resistor 34 and rectifier 32 to prepare the circuit for a further closing operation. Specification 868,253 is referred to.

Abstract: 1467488 Timing removal of inoperating conditions in open end spinning machines VYZKUMNY USTAV BAVLNARSKY 28 Feb 1974 [20 April 1973] 9025/74 Heading DID  In an open-end spinning machine each spinning unit has a time-control device for timing the individual operations of at least one operating element of the spinning unit, each device comprising at least one regulating element for individually adjusting a response time of the device whereby the start of operation of an operating element may be adjustably delayed, and a common regulating element is connected to all the devices for simultaneously adjusting the response times. Each time control device may comprise a capacitor Cl charged to voltage U2. When contact 32 is automatically or manually actuated, transistor T1 conducts, the capacitor discharges for a given time, and then is recharged to opposite polarity by voltage U1 until diode D1 conducts. Transistor T2 then conducts to hold contacts P1 of relay P on so that relay contacts P2 actuate clutch 21 driving a sliver feed roller, and to render transistor T1 non-conductive. Thus the clutch is actuated a given time after the actuation of contact 32, the time being adjusted by variable resistor 31 and by adjustment of voltage supply U2 common to the time control devices.

Abstract: 312,741. Kleiber, E., and Gilardi, P. March 26, 1928. Rubber substitutes ; resinous compositions.- An elastic mass capable of being vulcanized and used as a rubber substitute is obtained by treating petroleum with nitric acid or with sodium peroxide in the presence of soda lime or sodium acetate or with other oxidizing agent and distilling the neutralized liquid so obtained repeatedly over colophony, heating the distillate with a dilute alkali under pressure causing separation into three layers, and treating one or both of the upper layers with a rubber promoter, e.g. by adding glacial acetic acid and formaldehyde and raw rubber. From a syruplike mass so obtained an elastic mass capable of being vulcanized is obtained by the addition of acetone or alcohol. The residue obtained after the distillation over colophony is a hard resin which may be used as a substitute for copal for varnish.

Title: Improvements in or relating to processes involving reactions with lithium methylene and magnesium methylene
Inventor: DUCK EDWARD WILLIAM
IPC: C08F10/00
Filed: 1958-03-21
Abstract: Polymeric material the polymer molecules of which have a chain structure in which adjacent units are linked by a methylene group are made by bringing together at an elevated temperature (1) an organic halogen compound containing in its molecular structure a plurality of reactive halogen atoms, and (2) lithium methylene or magnesium methylene.  Examples of polymers which may be made by this process include polypropylene and polyethylene made from 1, 1-dichloroethane or 1, 1-dibromoethane and methylene chloride respectively, the polymers containing some terminal halogen as impurity.  Also a polymer containing benzyl units may be made from a dihalobenzene. The reaction is carried out in the absence of air and water and preferably in an inert gas atmosphere and in an inert liquid diluent, e.g. a hydrocarbon fraction or iso-octane, and may be made a continuous process.  The polymers obtained consist essentially of linear chains terminating with a halogen atom which may by after-treatment be converted into a nitrile or carboxylic acid group or removed with the formation of a terminal olefinic group. Specification 778,619 is referred to.ALSO:Organic compounds, e.g. hydrocarbons and halogenated hydrocarbons, containing at least one methylene group linking two atoms in their molecular structure are prepared by bringing together at an elevated temperature (1) an organic halogen compound containing in its molecular structure at least one reactive halogen atom and (2) lithium or magnesium methylene.  The product may be a linear or cyclic compound. Hydrocarbons which may be prepared include diphenyl methane from chlorobenzene, cycloparaffins such as cyclopentane and cyclohexane from a 1,4-dihalobutane and 1,5-dihalopentane respectively and a cyclopropene derivative from o-dihalobenzene. The halogen compounds used may be the bromo- or chloro-compounds.  Halogenated hydrocarbons of higher molecular weight may be made from the original halogenated hydrocarbon, which may contain more than two halogen atoms in its molecular structure, by mixing the reactants in the right proportions.  Thus a , o -dihalogen compounds may be made from two molar proportions of a dihalogen compound and one of the metal methylene compound.  The halogen compound may be the bromo- or chloro-compound and may be an aliphatic, alicyclic or aromatic compound.

Abstract: 541,489. Supply circuits for discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. May 27, 1940, No. 9304. Convention date, May 27, 1939. [Class 38 (iv)] [Also in Group XL] Starting, and pre-heating the electrodes of a gaseous discharge device is effected by supplying the device e.g. a lamp through a step-up auto transformer 8, the full (secondary) winding of which is connected to one electrode 2 of the lamp and a portion of the winding (the primary) is connected in a branch resonant circuit containing a reactional 10 and a capacitance 11 to the other electrode 3; the branch circuit supplies the heating current for both the filaments. As shown, the branch circuit includes the filament 3 and it supplies the filament 2 from a secondary 12 on the reactional 10 which is in the form of a transformer with air gaps 13 and a saturable magnetic shunt 15. When the lamp strikes the filament heating supply is reduced owing to the reduced flux through the secondary because of the magnetic shunt. In a modification the reactance 10 serving as a ballast is a plain reactor and the branch circuit is taken through the primary of an auxiliary transformer the secondary of which supplies the filament 2. In a further modification a secondary on the reactor 10 is connected to the filament 2 and to a tapping on the auto-transformer so that the voltage applied to it is the vector sum of the two sources which is much reduced when the discharge starts owing to the considerable phase-angle between them.
