IPC: C08K5/00
Filed: 1958-03-10
Abstract: Secondary amino azole disulphides of formula <FORM:0872456/IV (b)/1> where R and R1 are the same or different aliphatic hydrocarbon, cycloaliphatic hydrocarbon or aralkyl radicals, or where R and R1 together with the N form a single ring which may be interrupted by O, S or NH, and R2 is a 2-thiazole, 2-oxazole or 2-imidazole radical are prepared by reacting a thi-, ox- or imid-azolesulphenamide with sulphur.  The sulphenamide may be prepared by oxidising a mixture of the corresponding azole disulphide and secondary amine.  In a modification of the invention the amino azole disulphide is obtained directly by reacting a secondary amine, an azole disulphide and sulphur, preferably in the presence of an oxidising agent, specifically sodium hypochlorite or N-chloromorpholine.  In another embodiment, one mole of an aminemonosulphide is reacted with one mol of an azole disulphide to give a mixture of the amino azole disulphide and the azolesulphenamide and this mixture then reacted with sulphur.  Solvents may be used and the reaction between sulphenamides and sulphur may be catalysed by amines which exert a solvent action on sulphur, e.g. morpholine or cyclohexylamine. Reference has been directed by the Comptroller to Specifications 835,667 and 841,419.

Title: Automatic gain control for television receivers
IPC: H04N5/52
Filed: 1943-05-18
Abstract: 565,710. Automatic volume control. PHILCO RADIO & TELEVISION CORPORATION. May 18, 1943, No. 7891. Convention date, June 13, 1942. [Classes 40 (iii) and 40 (v)] In a television receiver adapted for the reception of video and synchronizing signals transmitted at different carrier frequencies, there is derived from the video carrier an automatic gain control voltage whose magnitude is determined substantially by the blanking level of the video carrier. Fig. 2 shows the last tuned I.F. transformer 15 of a television superheterodyne receiver feeding the second detector 17 and later stages (not shown). The I.F. output is also fed to circuits 19, 20 which together comprise a constant resistance circuit. The reactive elements of circuit 19 are seriestuned to the video I.F., while those of circuit 20 are parallel-tuned to the same frequency. Circuit 20 has a high Q-value and thus a voltage will build up across it corresponding to the video carrier strength and independent of the synchronizing pulses. This voltage is rectified at 21 and smoothed at 22, 23 to give an A.G.C. voltage for application to the R.F. and I.F. stages. In a modification, Fig. 3 (not shown), the I.F. is fed to a pentode in the output circuit of which is a critically coupled transformer of high Q value tuned to the video I.F. frequency and which feeds a diode to produce the A.G.C. voltage. U.S.A. Specification 2,347,248 is referred to.

Title: Improvements in or relating to machines for generating cams of the worm type
IPC: B23F15/00
Filed: 1934-03-13
Abstract: 436,521. Grinding cams. BISHOP, R., 145, The Vale, Golders Green, London. March 13, 1934, No. 7921. [Class 60] [See also Group XXII] In a machine for generating a cam of the worm type such as those used for the steering gears of vehicles, the blank is mounted on a rotary carrier and a plane control surface mounted on a fixed part of the machine is arranged to impart a bodily movement to the blank during its rotation to generate the required cam. In one form, for finishing by a fixed grinding-tool (not shown), a rough blank B is mounted on a vertical spindle 1 rotatable in a slide 3 movable in guideways 4, 5 on the frame 6. The slide 3 is connected to the frame by a pair of radius arms 7, 8 the pivots of which are mounted in self aligning bearings, Fig. 5. By this construction the slide 3 has a " parallel ruler " motion to move the blank in an arcuate path when the links move about the pivots 10. A traveller 13 is reciprocated along a horizontal guideway 14 by a crank arm 19 mounted on a driven shaft 17 and carrying a block engaging a vertical guide in the traveller. The latter carries an angularly adjustable control member 23 pivoted at 22 and engaged by a pair of rollers 27, 28 on a rocker 29 pivoted to the slide 3 so that as the traveller and member 23 are reciprocated, arcuate motion is imparted to the slide 3. The control member also carries a pair of racks 34, the teeth of which are out of alignment to avoid backlash. These racks are connected through a pair of pinions, spindle 30 and bevel gearing 32 to the blank spindle 1 which is thus rotated in unison with its bodily movement. By eliminating the radius arms and giving the slide 3 a purely vertical movement the machine may be adapted to produce true helical threads. The rack-and-pinion gearing may be replaced by flexible band mechanism for imparting rotation to the blank spindle. The control member 23 may differ somewhat from a flat surface to give variations of pitch to the workpiece. A modification for effecting the rough cut by milling, is also described.

To suppress oscillations derived from transient disturbances due to load conditions in an A.C. network I (Fig. 1) joined to an A.C. network II by a D.C. transmission link L, deviations in frequency from a nominal value f o  are measured at two points in network I and the respective difference values ##1 and ##2 are fed to respective amplifiers having transfer functions F 1  = a1 + b1/p + C 1 /p 2  &c. and F 2  = a 2  + b 2 /p + c 2 /p 2  &c., wherein p is an operator; a, b, c are constants fulfilling the following conditions: a 1  is not equal to zero, a 1  to a 2  differs from zero, b 1  + b 2  = 0, c 1  + c 2  = 0, d 1  + d 2  = 0 &c. The outputs of the amplifiers are fed to summing member E together with a signal from a potentiometer P corresponding to a desired value of an operating magnitude e.g. transmitted current or power. The summing member output is fed to a common regulator R for controlling converters S 1 , S 2  one of which operates as a rectifier and the other as an inverter depending upon the direction of power flow between the networks I and II. The transmitted power of the D.C. link will therefore vary in dependence upon the frequency deviations at the two measuring points, in addition to the normal control set at potentiometer P, and oscillations are thereby suppressed. The amplifier F 1  summing device E, regulator R and potentiometer P are arranged adjacent the converter S 2  and the control signal is transmitted to converter S 1  via a tele-link. Also the signal from F 2  is transmitted to E via a telelink as the first measuring point is adjacent S 2  and the second remote therefrom. The frequency measurements are obtained by measuring the speed of synchronous motors 10, 20 at the respective points. Fig. 2 (not shown) illustrates an arrangement whereby network I is stabilized or supported at two or more points, should the network be sufficiently large. In this case the D.C. link is divided into two branches and the network I into three parts. One branch is connected via a converter S 2  to a part 1 and the other via a converter S 3  to part 2. Fig. 3 (not shown) illustrates an arrangment wherein the network I is connected to two other A.C. networks via two D.C. links.
