Title: Improvements in and relating to typographical composing machines
IPC: B41B11/18
Filed: 1936-06-19
Abstract: 476,954. Type - bar - making machines. CLEMO, F. A. (Mergenthaler Linotype Co.) June 19, 1936, No. 17089. [Class 100 (iii)] Assembling matrices.- Means are provided for driving the matrix conveyerbelt and the star-wheel at a number of different speeds, in order to adapt them for handling matrices of different sizes, the speed of the belt being automatically varied as the magazine is changed, so as to travel more slowly with the larger matrices. The speed of the starwheel is suitably adjusted by hand. The parts are driven from a shaft G, Fig. 3, which is rotated by a belt O from the intermediate shaft. A gear G<2> on the shaft G is connected through a pinion H to the largest of three gears J<1>, J<2>, J<3> of varying size, which are secured to a common sleeve, so as to rotate together. The gears J<1>, J<2>, J3 mesh with three complementary gears K<1>, K<2>, K<3>, Fig. 7, which are separately and loosely mounted on an endwise movable shaft L. Any one of the gears K<1>, K<2>, K<3> can be connected to the shaft L by a spring pawl L<1>, mounted in a recess in the shaft, and having a bevelled head, which can enter keyways in the hubs of the gears as the shaft is moved endwise. The shaft is connected by gearing to the shaft of the starwheel E, a spring being interposed to absorb the shock of the larger matrices. The shaft L is adjusted endwise by a lever L<5> operated by a handle L<10>, the three positions of the shaft being indicated by a pointer and an index plate. The driving-pulley C<3> of the conveyer belt is similarly operated from the gears J<1>, J2, J<3> through a second set of complementary gears mounted on an endwise movable shaft N. The shaft N is automatically adjusted, in accordance with the magazine in use, by campieces on the magazines. To permit the starwheel and belt to be stopped without stoppage of the machine, a ratchet clutch, controlled by a handle, is interposed between the driving- shaft G and the gear G<2> thereon.

Title: Improvements relating to electric timing circuits
Inventor: LEGG MALCOLM
IPC: G04C23/12
Filed: 1965-04-23
Abstract: 1,124,492. Protective arrangements. A. REYROLLE & CO. Ltd. 22 April, 1966 [23 April, 1965], No. 17292/65. Heading H2K. [Also in Division H3] A time delayed switch for a protective system comprises a transistor-type Miller integrator timer in which the Miller capacitor is connected to a tapping point on the output resistor of the amplifier so that it is given a small charge at the commencement of the timing period. When a fault occurs a reed relay 10 makes a contact 11 so that a capacitor 60 coupled in Miller fashion between the output and input of an amplifier 50, 51, 52 commences to charge. Charging continues until the output from a potentiometer 64 is sufficient to change over the conducting conditions of a Schmitttype circuit 65-75 and so operate or release a tripping relay 75 depending upon whether it is connected by links 77 to the output of transistor 67 or 68. When the relay contact 11 is opened the capacitor discharges quickly through diodes 61, 62 and potentiometer 53, 63. In order to avoid timing uncertainties due to the difficulty of completely discharging the Miller capacitor 60, its upper terminal is connected to a tapping on the resistor load 54, 55 of the Miller amplifier so as rapidly to charge capacitor 60 to a small value prior to the main charging period. A time lag varying inversely with the input may be obtained by charging the capacitor from the protected supply. Alternatively (as in Fig. 2, not shown) a characteristic of the form IT = K, or 1<SP>2</SP>T = K or according to BSS142 may be obtained by feeding the input current (81) for the capacitor through a transformer to a shaping circuit (80). In addition, in Fig. 2, the. integrator amplifier uses complementary-type transistors (85, 88, 89) to reduce the threshold voltage and a complementary output switch is connected to the amplifier through a diode to operate the relay when the capacitor charge reaches a predetermined value.

Title: Improvements in or relating to electronic systems for controlling the speed of directcurrent motors
IPC: H02P7/26
Filed: 1956-06-06
Abstract: 834,569. Control of D.C. motors. RAIMBAULT, P. June 6, 1956 [June 11, 1955], No. 17439/56. Class 38 (3). [Also in Group XXXV] In a system for maintaining constant the speed of a D.C. motor used to drive a test-bench, the armature supply is derived from an A.C. supply through thyratrons, the grid excitation of which comprises an A.C. voltage, lagging 90 degrees with respect to the anode, voltage, and a superimposed regulating D.C. voltage representative of the speed and load of the motor. In Fig. 1, a motor M has a field connected through gas-filled valves V1, V2 to a secondary winding E1 of a power transformer T, and an armature connected through a compounding winding to the connection between the cathodes of a pair of thyratrons V3, V4, the anodes of which are connected to a secondary winding E2. A fixed value A.C. grid excitation voltage lagging 90 degrees with respect to the anode voltage is derived from a double dephasing bridge comprising fixed resistors R1- R4, variable resistors P1, P2 and capacitors C3, C4. A regulating D.C. potential is applied between a centre-tap A of a winding supplying the double de-phasing bridge and the cathode connection B. In Fig. 2, the regulating D.C. voltage at terminals AB is derived between the anode of an amplifying valve V5 and an anode of a voltage stabilizing valve V8, and is dependent on the voltage applied to a control grid of valve V5 through a resistor R8. The grid voltage comprises a first reference voltage and a voltage proportional to motor-speed, and a second reference voltage and a voltage approximately proportional to motor load. The first reference voltage is derived from a variable potentiometer P4 supplied from the anode of the stabilizing valve and is opposed by the voltage developed across a resistor R6 by the rectified output of a tacho-generator m coupled to the motor. The second reference voltage is developed across a potentiometer P5 by the rectified output of a winding Z and is opposed by the voltage approximately proportional to the motor load developed across a resistor R24 and a potentiometer P6 by the rectified output of a secondary of a current transformer T1 in the supply to the power transformer T. The resultant grid voltage is derived from the junction of resistors R13, R14. A reduction in speed reduces the voltage across resistor R6 so reducing the negative grid voltage of valve V5 and accordingly reducing the voltage between points A and B so as to increase the voltage applied to the armature of the motor and so maintain the speed constant. The speed to which the motor is controlled is adjusted by the potentiometer P4, and compensation for change in motor load is controlled by adjustment of potentiometers P5, P6. The rate of speed increase of the motor on starting is controlled by the rate of charging of a capacitor C9 through a resistor R9. A combination R13, R14, C16 is provided to prevent " hunting " during speed correction.

Abstract: 354,460. Universal joints. WEISS, C. W., 1050, Ocean Avenue, Brooklyn, New York, U.S.A. June 6, 1930, No. 17599. [Class 80 (ii).] In a universal joint, particularly for front-wheel drive motor vehicles, of the kind having two coupling members a, b having coacting teeth formed on their proximate faces with non-concentric grooves c intersecting at an angle and partly receiving drive-transmitting balls f the plane of which is self-maintained bisector of the angle between the shafts to give a constant velocity ratio, the reduced dedendum section 3 necessitated by the provision for an angular displacement of 40‹, is compensated by a reinforcing rib a<6> extending laterally between the teeth and either welded on or formed by milling. The axes of the grooves are compound curves formed on varying radii so that their angle of intersection, and hence friction and wear, are at a minimum when the shafts are in alignment. The reinforcing rib a<6> is formed by introducing a truncated milling cutter k between the previously formed teeth as shown in Fig. 3, part of which is a section on y-y, Fig. 4. The joint member is then rocked about its axis a<3> and about an axis at right-angles through the centre point a<4> so that the cut extends in a radial plane. Fig. 5 is a view in the direction of the arrow z, Fig. 4. The grooves c are then formed by a spherical milling cutter shown in Fig. 4 and the addendum a<8> is reduced so that it may enter between the teeth within the line of reinforcement. There is a centralizing ball d and lubricant enclosing shells g retain the members in operative relation.

Title: Improvements in and relating to processes for the production of amines and/or imines
IPC: C07C209/64
Filed: 1945-07-13
Abstract: Hydrogenation catalysts are prepared as follows:  (1) Cobalt or nickel-carbonate is precipitated by means of sodium carbonate in the presence of kieselguhr, the precipitate ignited at 100 to 200 DEG C. and reduced with hydrogen at 200 to 600 DEG C.  It is stabilized by slow superficial oxidation with air at room temperature:  (2) a nickel/aluminium alloy catalyst, after crushing is treated with caustic soda at 90 to 100 DEG C. until 75 to 80 per cent. of the aluminium is dissolved and is then washed free from alkali.ALSO:Amines are hydrogenated in the presence of a hydrogenation catalyst containing a hydroxide or carbonate of an alkali or alkaline earth metal such that the catalyst when slurried with water shows a pH greater than 7.  The reaction may be illustrated by the equations 2RNH2 \sX(R)2NH+NH3 and 2(R)2RH \sX (R)3N+RNH2, in which R is an alkyl group such as methyl, ethyl, propyl, butyl or higher alkyl group, aryl or aralkyl group such as benzyl or phenyl or other stable group such as alkoxy alkyl groups, for example methoxy methyl, methoxyethyl, ethoxyethyl, (methoxy methoxy) ethyl, (ethoxymethoxy) ethyl and (isobutoxymethoxy) ethyl. The catalyst may be nickel, cobalt, fused copper cobalt, copper chromite or a nickel alloy.  In the examples: (1) (ethoxymethoxy) ethylamine is reacted in the presence of a nickel on kieselguhr catalyst or a nickel-aluminium alloy catalyst with cyclohexane to give di-[b -(ethoxymethoxy) ethyl] amine; (2) (isobutoxymethoxy) ethyl amine is reacted with a cobalt or nickel on kieselguhr catalyst giving di-[b -(isobutoxymethoxy) ethyl] amine; (3) di-[b -(isobutoxymethoxy) ethyl] amine is reacted with a nickel on kieselguhr catalyst giving tri-[b -(isobutoxymethoxy) ethyl] amine; (4) tetramethylenediamine or hexamethylene diamine are reacted with a nickel on kieselguhr catalyst to give pyrrolidine and cyclohexane imine respectively.  Alkoxyalkoxyalkylamines are prepared by hydrogenating the corresponding alkoxyalkoxy nitriles in the presence of nickel, cobalt or copper chromite.
