Title: Improvements in or relating to overload release devices
Inventor: MEREDITH WILLIAM CHARLES
IPC: F16D43/206
Filed: 1962-05-18
Abstract: 1,048,124. Overload release positive clutches. CAMPBELL & ISHERWOOD Ltd. Aug. 16, 1963 [May 18, 1962], No. 19184/62. Heading F2C. An overload release positive clutch between a driving shaft 10 and a driven sleeve 11 comprises rollers 19 engaging radial wedge-shaped grooves 15 in a flange fast with the driven sleeve and caged in slots in a flange 17 rotatively fast with the driving shaft, increasing torque loading causing the rollers to ride out of the grooves and force an engaging plate 20 rightwards against the bias of adjustably compressed springs 21 acting through a thrust plate 25, a main ball 24 and three trains of balls 23, 22, the latter engaging a chamfered surface 26 around the inner side of the engaging plate. Additionally, when stationary, and at relatively slow speeds, masses 34 are biased radially inwards of a carrier 32, 38 fast on the driving shaft 10 by springs so that cam faces 35 at their inner ends engage a cammed spigot 36 on the thrust plate 25 to reinforce the springs 21 in maintaining the clutch in engaged condition. Thus under these circumstances, a relatively large torque can be transmitted between the driving shaft 10 and the driven sleeve 11 before the rollers 19 ride out of the grooves 15 and force the engaging plate 20 towards the carrier 32, 38 for complete clutch disengagement. At relatively high speeds, however, the masses 34 fly radially outwards against the bias of their springs, so that their cam faces 35 no longer engage the cammed spigot 36 on the thrust plate 25. The springs 21 then alone maintain the clutch engaged, so that disengage. ment can be effected by a smaller transmitted torque. Re-engagement is effected by depressing a button 39, so that pins 40 push the engaging plate 20 back over the balls 22 &c. to the position shown. A housing 14 surrounding the clutch acts as an oil reservoir.

Title: Receiver for unmodulated-frequency a.c. track circuits
IPC: B61L1/18
Filed: 1960-05-31
Abstract: 896,187. Signalling over power circuits. COMPAGNIE DE SIGNAUX ET D'ENTERPRISES ELECTRIQUES. May 31, 1960 [July 15, 1959], No. 19292/60. Class 40 (4). In a receiver which only accepts signalling frequencies different from the mains frequency and its harmonics, a transformer is provided between the receiver and power lines and a hand-pass filter connected to a secondary winding of the transformer selects the signalling frequency and transmits it via a transformer and transistor arrangement so that a relay may be operated, there also being a disabling device which saturates the transistor in case of current surges in the lines. A transformer A couples the power lines, which may for example supply electric power for tractive purposes, to a filter 6 and disabling device 11. A signalling current which is chosen to lie between two consecutive harmonics of the power current, is applied via the filter 6 and transformer 10 to the base of a transistor 10 which then " conducts " and so causes the operation of relay 23. A D.C. bias, which is dependent upon the load in the power circuit, is supplied by disabling device 11 to the base of the transistor 16, the variation of the bias causing the transistor to work at different points of its characteristic (Fig. 2, not shown). The components of device 11 are so chosen that if a succession of high voltage power pulses occur, then the transistor will be saturated and although the pulses may " break through " the filter, relay 23 will not be operated.

Abstract: 1,070,372. Impulse transmitters. PRESTO DIAL Inc. May 11, 1964 [June 14, 1963], No. 19461/64. Heading H4K. In an automatic dialling device having a plurality of cams each of which " stores " a particular telephone code by means of a number of teeth on its periphery which teeth cooperate with a switch so as to generate impulses corresponding to the particular telephone code when the cam is rotated, each cam is provided with a recess 37 (Fig. 3) extending from its periphery to a square section central bore whereby the cams may be readily replaced. The driving shaft 18 is of square section and is driven by a synchronous motor 10 (Fig. 2). The cams are retained in their respective positions on the shaft by means of a spring 35. The micro-switch 31 is aligned with any one of the cams by means of an index knob 26, the spring 27 (Fig. 3) which supports the switch engaging a corresponding groove 29 in the casing 13. Switch guide 38 engages an annular groove 39 formed in each cam. In operation, the motor is started whereby a switch 22, controlled by a cam 21 on the driving shaft 18, operates so as to keep the motor energized for one complete revolution of the shaft. The micro-switch 31 may be connected directly in the line loop whereby its operation under the influence of teeth 36 causes the required, transmission of impulses. Alternatively it may energize a solenoid which actuates the cradle switch contacts of an associated handset (Figs. 4 and 5, not shown) so as to produce the impulses.

Title: Method for making phenol
IPC: C07C37/58
Filed: 1947-07-25
Abstract: In the preparation of phenol by passing benzene vapour and an oxygen containing gas at a pressure of more than 500 lbs./sq. inch through a reaction zone at a temperature between 650 DEG  F. and 1225 DEG  F. in the absence of solid catalyst, the yield is improved by the addition of a minor proportion, i.e. from 0.2 per cent to about 3.0 per cent by volume based on benzene, of an organic compound containing hydrogen, which under the conditions of the reaction is a better hydrogen donor than benzene and is in the gaseous phase and which has a "potential hydrogen donor ability" value, as defined in the Specification, greater than 2.5.  Suitable hydrogen donors are cyclohexanol, cyclohexanone, cyclohexene, tetrahydronaphthalene, 2-ethyl-3-propyl acrolein, actaldehyde, n-hexane, diethyl ether, aniline, turpentine, n-hexene, cracked gasoline and particularly cyclohexane.  The invention may also be carried out by partially hydrogenating the benzene prior to the oxidation to produce the desired proportion of hydrogen donors. Optimum reaction times, temperatures, proportions and pressures; the dimensions and construction of the reaction tube and the nature and proportion of the inductor are interdependent. Suitable values for the above are indicated.  In a preferred embodiment of the invention, the benzene is separated from the phenol and other oxidation products and recycled with the addition at each recycle stage of a further small amount of the reaction promotor.  This may be added as such or may be formed in situ by continuously hydrogenating a proportion of the recycled benzene prior to its admission to the reaction zone sufficient to incorporate 0.2-3.0 per cent by volume of hydrogenated benzene.  Specification 459,920 is referred to.
