Title: Improvements in flexible couplings for shafts and the like and in applications of the same
IPC: F16D3/44
Filed: 1931-01-15
Abstract: 370,985. Driving gear for electric railway vehicles. TWINBERROW,J.D., 38, Victoria Street, London. Jan. 15, 1931, No. 1426. [Classes 79 (ii) and 79 (iii).] A flexible coupling, applied to driving electric railway vehicles, comprises an intermediate Oldham disc l, free to slide on diameters respectively at right-angles relatively to the driving and driven members, the sliding connection with either or both diameters being a multiple tooth and groove one, i<1>, l<1>, means permitting universal movement in addition to parallel displacement being provided. The outer teeth and grooves i<1>, l<1> may be dovetailed as shown. The driven member is a track wheel k, the driving member a toothed wheel i meshing with a pinion on the shaft of the electric motor a and rotatably mounted on a bush h on a fixed flanged trunnion e. In the form shown in Fig. 1 the disc l engages coupling memberspl, p2 having a peripheral toothed connection with the coupled members i, k, their teeth l<2> being developed cylindrically at the ends of the two diameters about a transverse axis to permit the coupling members to tilt about axes at right-angles to each other. In another construction the disc l directly engages the toothed face of the driving wheel i or a toothed annular ring bolted to it, and its other face has axial lugs on a diameter at rightangles to the grooves and extending into universal joints similar to those described in Specification 165,162. These joints permit angular movement about a diameter of the wheel by rotation of inner lug-engaging members in bored outer members, and angular movement about a diameter at right-angles together with parallel displacement by sliding of the lugs in the inner members. This form is also shown with two large ribs having dovetailed outer sides replacing the multiple teeth l<2> on the disc l. A further modification of it provides continuous automatic lubrication through a radial port in the trunnion flange e communication through further ports with all parts of the gear. A dust-excluding casing n may be supported on arms bolted to the motor casing a, Fig. 20, sufficient clearance between the casing and trunnion flange being allowed to accommodate the tilting movement. The casing is retained in position by springs. One or more inner closing plates g may be fixed to the axle and bear on suitably stepped faced parts of the trunnion e or they may be fixed to the trunnion and be clear of the axle, as shown, or bear on it through spring means. Fig. 20 shows the motor casing a extended on each side to be bolted directly to the channelled cross members c, d of the vehicle. The extension b has bolted to it the trunnion flange e, sufficient clearance being provided therein to accommodate movement of the vehicle in operation. Distance-pieces are interposed in the connection to the cross member d to provide clearance for facilitating dismantling the motor.

Title: Improved process for the manufacture of organo-silicon polymers and products produced thereby
IPC: C08G77/06
Filed: 1941-02-10
Abstract: Highly viscous heat convertible resins suitable for impregnating glass fibres, tape and like insulating materials are p  obtained by further polymerising silicones, comprising principally the structural unit:- <FORM:0561136/IV/1> where R is either alkyl or aryl, by treating the aryl silicones with acids while heating or by treating alkyl silicones with an oxidative agent while heating to about 200-300 DEG  C.  Silicones containing both aryl and alkyl radicals are treated by both methods, e.g. by heating them with hydrochloric acid while blowing air therethrough.  The silicones are prepared by the hydrolysis of organo substituted silicanes obtained by the action of Grignard reagents on silicon tetrachloride or ethyl orthosilicate. The effect of the further polymerisation is to remove organic radicals and substitute oxygen therefore, whereupon cross linkages of the Si-O-Si unit to side chains occur.  The polymerisation is preferably stopped while the product is still in the viscous stage and soluble in toluene.  Phenyl ethyl silicone is heated to 170-180 DEG  C. while water and hydrochloric acid is added slowly the reaction being hastened by a trace of ferric chloride; benzene is evolved and a sticky viscous liquid obtained.  Further heating converts it into a flexible non-tacky infusible and insoluble substance.  The preparation of phenyl ethyl silicone is described in Specification 561,226.

Abstract: 693,562. Overtaking articles. IMPERIAL CHEMICAL INDUSTRIES. Ltd. Jan. 24, 1951 [Jan. 24, 1950], No. 1830/50. Class 117 Hollow articles having one end closed and the other open, are dropped down tube 8 and are fed therefrom one by one by escapement mechanism 10, 12, the plungers 10, 12 of which are withdrawn in turn by crank 32 the movement of which passes to the plungers through crank arm 34 and rocker 33 against rotary springs 37, 39. The articles thus fed are sorted by annular drum 1 driven stepwise from a driving shaft by a general movement, the rotating pin 23, engaging in slots 19 formed externally in the wheel, and the drum being formed with hole 2. alternate holes each having a pin 3 fixed therein. Thus an article fed with closed end forward passes through the empty holes 2, and then through passage 7' in fixed core 6, and finally passes out through the appropriate hole 2 to outlet tube 15, whilst an article fed with open end forward falls on to a pin 3 and is carried' around, being held in by shield 17 until discharged through the same outlet tube 15, so that all the articles are thus uniformly orientated. Plunger 25 co-operating with slots 21 formed in the drum 1 so as to hold firm the latter between indexing movements, is driven from driving shaft 22' through cam 24 and lever 26, and shaft 31 is driven therefrom through 2-in-1 reduction gears 29, 30. The position of fixed core 6 may be reversed so that the article makes steps of falling into hole 2, into passage 7, into lower hole 2, and intoanother tube 15 successively.

Title: Improvements in or relating to modulating circuit arrangements
Inventor: STARKS-FIELD ALFRED BENJAMIN
IPC: H04N5/18
Filed: 1956-01-19
Abstract: 799,052. Amplitude modulating systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 7, 1956 [Jan. 19, 1956], No. 1840/56. Class 40 (5). The relationship between the mean anode current of an anode modulated valve and the instantaneous modulating signal is linearized by feeding back a signal proportional to the mean anode current of the valve to the input of the modulating signal amplifier. The modulating signal is amplified at V1, V2 and applied via a cathode follower V3 to the modulating valve V4 in the anode circuit of the modulator valve V5. Carrier is applied to the grid of the modulator valve V5, and the modulated output is obtained from a tuned circuit L1, C6 in the anode. The D.C. cathode potential of V5 is controlled by a cathode follower V6. The modulator circuit is shunted by a resistor R2. The voltage across R2 is proportional to the current passed by V4, and the voltage across the common anode load resistor R1 is proportional to the sum of the currents passed by V4 and V5. Hence by deducting the former voltage from the latter, a voltage proportional to the current passed by V5 is obtained. Accordingly, the two voltages are fed back in phase opposition via resistors R4, R3 to the input of the modulating signal amplifier. In a modification, Fig. 2 (not shown), the valve V4 shunts the modulator V5; and in a further modification, Fig. 3 (not shown), the resistor R2 is omitted and the feedback voltages are taken across a resistor in series between the cathode of V4 and the tuned load L1, C6.
