Title: Improvements in or relating to non-linear thermionic valve stages
IPC: H04Q1/30
Filed: 1937-11-11
Abstract: 505,500. Valve circuits. HADFIELD, B. M. Nov. 11,1937, No. 30919. [Class 40 (v)] A valve repeater comprises a pentode valve V1 biassed to cut off which has a high impedance in its anode circuit so that when a signal is received, current flow through a directly coupled valve V2 which is normally passing current is stopped, and a relay R in the circuit of a subsequent valve V3 is operated to repeat the signal. Alternatively the relay may be polarized and have windings in the anode circuits of both slave valves so that both makes and breaks are positively repeated. In the former embodiment valve V1 is biassed to cut off by the tapping on resistance R6, the resistance being of the order of 5,000-10,000 ohms to prevent grid current. Valve V2 is arranged to be normally passing grid current and valve V3 is biassed to cut off. When a signal is received valve V1 passes current and, in view of the high impedance of R1 the voltage on the plate of VI will drop almost to zero. This voltage drop will be communicated to the grid of valve V2 but its effect will be delayed until the grid current of V2 is overcome. Then the anode flow of V2 ceases so that the potential on the grid of V3 rises and the relay R is operated to repeat the signal. If the signal is alternating a condenser as C1 or C2 is required to prevent the relay R releasing on the negative half cycles. The relay R can be replaced by a polarized relay 1R (Fig. 2) having windings in the anode circuits of both second and third valves V5, V6 which in this embodiment are low impedance pentodes, the relay repeating both makes (when winding b is energized) and breaks (when winding a is operative) of the signal. As the combined anode and screen currents of valve V5, V6 is. constant, the valves can be provided with automatic bias by resistance B10. Condenser C4 enables an A.C. signal to be repeated and condenser C5 prevents the generation of low frequency oscillations. The invention can be used as a valve voltmeter of the slide back type. The relay 1R, Fig..2, may be made to operate at a rate determined by the constant of R7 and C4 if the potentiometer R12/14 is dispensed with and the cathode of V4 is taken back to a sliding contact on R10. This is due to hysteresis effects caused by small differences in the anode currents of V5 and V6. Specirication 472,728 is referred to.

M. ; 63, Pollard Road, Mountain Lakes, New Jersey, U.S.A.) Oct. 17, 1930, No. 31196. Convention date, Oct. 23, 1929. [Class 38 (iii).] Cameras and sound-recording machines are driven by service motors 30, 31 connected to the rotor and stator windings of a " distributer " 4, the stator of which is supplied through a frequency booster 3 from a main supply switch S1. The machines 3, 4 and also a pilot generator 5 are driven by a main motor 2. The machines 2, 4 are six-poled whilst the machine 3 is four-poled. Prior to starting, with switch S1 closed, switch S2 is closed to the left, causing machine 3 to turn if it is not on a deadcentre to a position of equilibrium. Switch S2 is opened and switch S3 is closed to the left, owing to the difference in pole number of machines 2 and 3, the former cannot be on a dead-centre, so it turns to a position of equilibrium. By closing and opening switch S2 to the right, the machine 3 develops an intermittent torque, causing an oscillation of the distributer 4. During the oscillations, switches S4, S5 are closed, thus supplying the service motors with a single-phase stator current through a resistance 80 which is gradually reduced to zero. This action causes the service motors to break out of dead centre and to become aligned with the distributer. Switch S6 is now closed to supply three-phase current to the stators of the service motors, and switch S3 is closed to the right to cause machine 2 to accelerate as an induction motor with variable impedances 38, 39, 40 in its rotor circuit. A control motor 59 in parallel with the service motors is loaded with a flywheel and controls the acceleration of the main motor 2. Its rotor current is applied to the grid of a phase detector 58, and its rotor potential is applied through an attenuation network 65 to the anode of the detector. This detector control the grid bias of rectifiers 47, 48, 49 supplying: saturating current to the impedances 38, 39, 40 and by tuning the network 65 to a valve intermediate the initial and final frequenciessupplied by the rotor of the distributer 4, a slow initial, then a fast intermediate and finally a slow final stage of acceleration is obtained for the motor 2. At full speed, the pilot generator 5 and detector 55 control the speed to maintain it constant. Specifications 292,528, 297,153, and 319,274, [all in Class 38 (iii), Electric motor control systems &c.], are referred to.

Title: Process for the preparation of sarcosine
Filed: 1955-11-01
Abstract: Sarcosine is prepared by dispersing a monohaloacetic acid or salt thereof in finely divided form (solid, liquid or solution) in methylamine at room temperature or below, preferably around 0 DEG C., using methylamine in considerable excess over the theoretical amount.  The reaction is completed by standing at room temperature or by heating to 20-130 DEG  C. in a pressure vessel.  When anhydrous methylamine is used the temperature is preferably below -6 DEG  C. Alkali may be present in the methylamine to absorb the hydrogen halide liberated, to decompose any methylamine salt of sarcosine formed and to produce the alkali salt of sarcosine if this is desired.  Alternatively, the alkali may be added after the haloacetic acid salt.  Examples are given of the process using chloracetic acid and its sodium salt as reactants, a minor proportion of disarcosine being obtained as by-product. Bromo-and iodo-acetic acids are also mentioned and the alkali may also be potassium hydroxide or carbonate, calcium oxide or hydroxide, pyridine, piperidine or excess methylamine.  The mixing may take place as low as -70 DEG  C. and is preferably carried out slowly with vigorous agitation.  Batch processes are preferred to continuous operation.
