A toothed wheel 10, rigid with the planet carrier 8 of an epicyclic gear 4, 5, 6, 7 in a gearing train such as a machine tool saddle gearbox feed mechanism driven by a worm 1 from the machine lead screw, is normally engaged by a roller 11 under the action of a spring-loaded toggle 16, 17, 13 so as to station the carrier 8 and allow drive. Upon overload, caused by the saddle gearbox striking or being struck by a stop on the machine frame, or otherwise, the toggle 16, 17, 13 is thrown over by the reaction of the wheel 10 on the roller 11, and the drive is disconnected, the toggle 'resting against a stop 23. Initial connection and manual disconnection of the drive is effected by turning a knob 24 fast with a pivot shaft 14 keyed to a lever 13 forming one toggle arm. The toggle is loaded by a spring 15 acting to expand a telescopic second toggle arm 16, 17, and the throw-out torque may be adjusted by turning a knob 21 fast with a shaft 20 on which the member 17 is eccentrically pivoted. In Figs. 3 and 4 (not shown), the planet carrier 8 is respectively made the driving and driven member of the epicyclic gear, the wheel 10 being then rigid with a reaction sun gear thereof.

Convention dates, July 17, 1933. [Class 29] Absorption machines and systems.-The absorber of a continuously-acting machine of the kind employing a pressure-equalizing inert gas comprises two or more sections through at least one of which the absorption liquid and the mixed refrigerant vapour and inert gas flow in the same direction. The absorber may comprise upper and lower sections separated by a partition G<1>, Fig. 2, and provided with internal baffles and external heat-radiating fins. The weak liquor from the gas separator connected to the generator passes through the pipe D<1> into the upper section of the absorber and thence through the tube G<4> into the lower section which has a strong liquor outlet to the generator, while the mixed vapour and gas from the evaporator enter the lower section through the pipe E<1> and pass through the central duct G3 to the upper section from which the inert gas, together with unabsorbed vapour, passes through a pipe A<2>, in heat-exchange with the pipe E<1>, to the evaporator. In a modification, the absorber consists of tubular sections H, K, Fig. 3, the weak liquor being supplied to the upper section through the pipe D<1> and the mixed vapour and gas to the lower section through the pipe E<1>. In another arrangement, the absorber comprises tubular sections M, P and an intermediate cylindrical section N. In this case the mixed vapour and gas passes from the evaporator E to the section N through the pipe E<1> and thence by way of the inverted U-pipe N<3> to the section P from which it passes to the section M and returns to the evaporator through the duct F which forms a heat-exchanger with the pipe E<1>. The weak liquor from the gas separator D enters the section M through the pipe D<1> and, after flowing through the sections N, P by way of the pipes M<2>, N<2>, passes through the pipe P <1> into the lower part of the section N which forms a strong liquor reservoir and is connected by the pipe A<1> to the generator B. The condenser C communicates with a gas separator C<1> connected by a pipe C<2> to the pipes N<3>. Fig. 7 shows a modification of the latter arrangement in which the mixed vapour and gas flows through the sections N, P before passing to the section M. Specification 389,674 is referred to.

Abstract: 836,882. Moulding concrete railway sleepers. DOW-MAC (PRODUCTS) Ltd., and ROBERTS, W. K. May 27, 1957 [May 28, 1956], No. 16460/56. Class 87(2). [Also in Group XXX]  In moulding a concrete railway sleeper a socket 52, Fig. 1, for a rail holding bolt 15 having undercut portions 51 for receiving the head 54 of the bolt is formed by casting the sleeper, e.g. bottom upwards in a mould 26, Fig. 2, around a core 30 having an enlargement for forming the undercut portions 51 which is collapsed and the core 30 removed when the sleeper has set sufficiently to be self supporting. The core 30, as shown in Fig. 4, is formed in three parts 40, 41, 42, and is of rectangular cross-section, projections 39 on its two wider faces forming said enlargement. Metal bearing surfaces for the bolt head 54 are provided by an apertured plate 46, which is mounted in grooves 38 in the core 30 so that its outer periphery becomes embedded in the concrete. To collapse the enlargement the part 41 is removed and the parts 41, 42 closed together and then removed. Two notches 44 are provided at diametrically opposite edges of the core 30, one in each projection 39. There are thus formed abutments 55 which limit the rotation of the bolt head 54 when the bolt 15 is assembled in the sleeper, by passing the T-shaped head 54 through the rectangular aperture 47 and rotating it through 90 degrees. In place of the core 30 there may, alternatively, be used a core of rectangular tubular form having 156 projections from a pair of opposite sides which may be withdrawn into the tube after casting. Also the recesses 51 may be formed at the bottom of the sleeper.

Abstract: 730,779. Automatic amplitude control systems. SOCONY-VACUUM OIL CO., Inc. July 1, 1952, No. 16592/52. Class 38 (4). [Also in Groups XXXVI and XL (c)] In. a cathode-ray oscilloscope for displaying signals indicating the performance of an internal-combustion engine and comprising separate horizontal and vertical time base generators synchronized with the engine (see Group XXXVI), the amplitudes of the time bases are automatically maintained constant in spite of variations in the engine speed. As shown, the vertical time base generator comprises a resistor 54 and constant-current pentode 55 in series with a capacitor 49 which is periodically discharged by a thyratron 41 and the horizontal time base generator comprises similar components 84, 85, 76-79 and 74. The negative sawtooth output from the horizontal time base generator is applied via capacitor 95 to the anode and cathode respectively of the left and right-hand sections of a double diode 92 and the cathode of the left-hand section is maintained at a stabilized potential of approximately 50 volts, thereby clamping the positive peaks of the sawtooth at this level so that if the amplitude of the sawtooth exceeds 50 volts the right-hand section of valve 92 becomes conductive and changes capacitor 94 negatively, the resultant negative voltage being applied to control grids of pentodes 55 and 85, thereby reducing the rate of change of the time base capacitors and hence reducing the amplitudes of the time bases.

Abstract: 444,998. Picture amplifiers. ARDENNE, M. VON, 19, Jungfernstieg, Lichterfelde-Ost, Berlin. June 7, 1935, No. 16642. Convention date, June 7, 1934. [Classes 39 (i) and 40 (v)] To amplify the brightness of pictures a plurality of tubes 1, Fig. 1, each of which comprises a photo-electric cathode 2, an electrostatic electron-optical system 4, 5 and a fluorescent screen 3, are arranged in cascade by optically coupling, e.g. by means of the lens 6, the screen of one tube with the cathode of the subsequent tube. The picture to be amplified is focused on to the cathode 2 of the first tube. In another form, the cathodes are transparent and the tubes are separated by transparent insulating layers 8, Fig. 2. The product of the enlargement obtained by the electron-optical system and that obtained by the optical coupling between two tubes may be equal to one. The picture to be amplified, or that formed on any screen, may be reproduced on the succeeding cathode by means of a hollow parabolic mirror arranged around the rear end of the tube. The maximum sensitivity of the cathode of the first tube corresponds to light which has the same colour as that of the picture to be amplified, and the maximum sensitivity of the cathodes of succeeding tubes corresponds to light of the shorter wave lengths, e.g. blue light. Similarly, the screens of the intermediate tubes are adapted to emit blue light and the screen of the last tube is adapted to emit light which corresponds to that at which the eye is most sensitive. The apparatus may be housed within a light-proof box provided with an opening through which the screen of the last tube may be viewed.
