Title: Cam device for varying speed of an object which is being conveyed
IPC: F16H37/12
Filed: 1951-05-25
Abstract: 701,458. Conveyers. JOHNSON & JOHNSON. May 25, 1951 [June 1, 1960], No. 12346/51. Class 78 (1) [Also in Group XVI] A cam device for accelerating or retarding the speed of an object which is being conveyed, e.g. a portion cut from a travelling web, comprises two spaced-apart and oppositely-rotating cams 14, 15 which have surfaces of different coefficients of friction for engaging the opposite parallel faces of the object moving between them, the surface of one cam being of progressively-increasing radius and that of the other of correspondingly-decreasing radius. The cams 14, 15, Fig. 1, which are shown as ready to deal with the cut-off portion of a moving web 10, are formed with involute surfaces generated from the same base circle and rotated in opposite directions at the same angular velocity by a common source of power. The cam 15 is surfaced with a material, such as rubber, having a high coefficient of friction. In operation, the leading edge of the web is engaged between the points of maximum radius of the cam 15 and smallest radius of the cam 14 immediately prior to the operation of the cutting, rolls 12. The cut portion O is then pressed by the cam 14 against the cam 15 which gradually retards its speed until it can be deposited without shock on a transverse conveyer 19, comprising two endless chains 21, 22 provided with spaced upstanding posts 24 to engage the cut portions ; the portion O is released by the cam 15 as soon as it is deposited on the conveyer but is still engaged by the cam 14 for a short period so as to provide a drag which ensures that the trailing edge of the cut portion will be engaged by the appropriate posts 24. In the'modification shown in Fig. 7, objects O are fed by a conveyer 22 to a pair of parallel ways 27 and are there engaged by a pair of cams 14, 15 which operate so as to move the object with accelerating speed to a transversely-disposed travelling belt.

Title: Improvements in or relating to automatic telephone systems
IPC: H04Q3/00
Filed: 1951-05-29
Abstract: 686,437. Automatic exchange systems. ERICSSON TELEPHONES, Ltd., and DRYSDALE, L. H. May 29, 1951, No. 12536/51. Class 40 (iv). In a system using singlemotion final selectors controlled by marker switches as described in Specification 625,704, a further digit received after a selector has been positioned on a party line outlet causes the marker to select an appropriate code ringing circuit. As shown, line, release and dialling relays AA, BB and CC operate in the usual manner in response to impulse trains incoming to the final selector, dialling tone from lead DT being effective over LT when group selectors are not provided. The first impulse train is repeated to marker switch MM and at the beginning of the second impulse final selector SS is started over wiper MM7. According to the value of the first digit, earth markings are extended over wipers MM7 - MM4 to control contacts of the selector which moves by selfinterruption to the first unmarked contact. Only the digits 1 to 5 are used, relay EA operating over level MM2 if other digits are received so that busy tone is effective from lead BT. When the dialling relay CC falls back, relay E operates and the second impulse train is repeated directly to the final selector. Re-operation of CC pulls up EA and the marker steps over wiper MM1 to contact 12. Relay LT operates and the third impulse train moves the marker to select a code-ringing lead RL1 to RL0 at wiper MM8. During the slow release of LT after CC falls back, busy test over wiper SS3 is effected by relay H which operates at free outlets and disables the busy tone circuit. If the outlet is free, relay FF pulls up over a periodically earthed lead CS and connects the selected code ringing lead to the line. When the called subscriber answers, relay F operates to disconnect the ringing circuit and disables FF so that the speech circuit is completed. On completion of the call, AA falls back and releases all the operated relays, while the marker and selector are restored to normal over wiper MM3.

Abstract: 1,165,653. Rectifying. BROWN BOVERI & CO. Ltd. 15 March, 1968 [17 March, 1967], No. 12830/68. Heading H2F. In a three-phase rectifier system in which the output is regulated by transductors 3 and having capacitors 11 for reducing excess voltages produced by charge storage effects in the semi-conductor rectifiers, the effect of capacitors 11 on the conduction angle of transductors 3 is reduced by injecting a phaselagging current to the junctions of rectifiers 4 and transductors 3. The output maybe adjusted by controlling the D.C. bias on control windings 33 of the transductors 3 or, as shown, by adjustment of transformer 9 or resistors 10 which control the A.C. current in the controlled winding 33. Resistors 1 and inductors 2 inject a current into transductors 3, lagging by 60 degrees behind the appropriate phase voltage, so as to prevent the charging currents of capacitors 11 reducing the effective conduction angle of transductors 3. In Fig. 5 (not shown), inductors 2 are omitted and resistors 1 are connected to the upper ends of appropriate transductors 3 so as to provide the necessary phase lag.

Abstract: 316,914. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). May 3, 1928. Ester condensation products. - Resinous products are obtained by condensing a polyhydric alcohol such as glycol, glycerol, sorbitol or mannitol, partially esterified with a monobasic acid, with a polybasic acid or its anhydride, to complete the esterification. The partial monobasic acid ester may be formed by esterifying a polyhydric alcohol with insufficient monobasic acid for complete esterification, or by treating a completely esterified polyhydric alcohol, such as linseed or china wood oil, with a polyhydric alcohol, preferably in excess and in the presence of a catalyst such as the alcoholates of alkaline earths. The product is then treated with the polybasic acid or its anhydride. Suitable monobasic acids are aliphatic or aromatic carboxylic acids or resin acids. Phthalic acid is a suitable pulybasic acid. In examples, (1) glycerol is treated with colophony and the product treated with phthalic anhydride ; (2) a mixture of glycerol mono- and di-benzoate is heated with phthalic anhydride; (3) glycerol and linseed oil are heated together in the presence of carbon dioxide, and the product is heated with phthalic anhydride; (4) the initial reaction of Example 3 is effected in the presence of calcium glycerolate, and the second reaction is completed in the presence of nitrogen, carbon dioxide or other inert gas; (5) linseed oil is heated with ethylene glycol in the presence of calcium glycerate, and the product heated with phthalic anhydride as in Example 4; (6) linseed oil and mannitol are heated in the presence of calcium glycerolate, and the product treated with phthalic anhydride. The resins are soluble in drying and non-drying oils and in other solvents such as acetic acid esters, glycol ethers, chlorhydrocarbons, acetone, aromatic hydrocarbons and mixtures such as benzene and alcohol.
