Title: Hybrid transformer
Inventor: CRAGG WILLIAM DONALD
IPC: H04B1/58
Filed: 1967-02-28
Abstract: 1,115,216. Hybrid transformer circuits. STANDARD TELEPHONES & CABLES Ltd. 28 Feb., 1967, No. 9360/67. Heading H4R. The balancing network of a two-to-four wire hybrid transformer circuit is automatically adjusted in accordance with error signals which are derived from signals in a narrow frequency band extracted from the send pair and the receiving pair. Fig. 2 shows one embodiment in which the balancing network for the hybrid circuit includes variable resistors R 1  and R 2  which are adjusted in accordance with error signals derived by filtering from the incoming signals on line 3 frequencies of, e.g., 800 c.p.s., by filter F1. The output of filter F1 is applied to a phase shifter 6 in order to obtain signals in quadrature which are applied to multipliers 7 and 9, to the other inputs of which are applied the signals selected from the outgoing line 4 by the filter F2, which is tuned to the same frequency as filter F1 The output of the multipliers is integrated in integrators 8 and 10 and the resulting signals adjust the values of the respective resistors R1 and R2, which may be field effect transistors, Fig. 3 (not shown). The integrator output signal are representative of the echo signal fed from the receive line to the send line via the unbalanced hybrid circuit. Signals from the subscriber's line 5 have no effect on the integrator outputs since they do not reach the input of filter F1 due to the presence of amplifier A1 while components of the subscriber's line signal which pass through filter F2 are uncorrelated with the signals from filter F1 and do not therefore produce an output from the integrators. In a modified system, Fig. 4 (not shown), the input of filter F1 is connected across the balance network since no signal from the subs line 5 reaches this point. In an alternative arrangement only one error signal is derived, and the resistors R1 and R2 are adjusted simultaneously, Fig. 5 (not shown).

Title: Improvements relating to a mechanism for producing intermittent rotary motion
IPC: C03B11/16
Filed: 1941-07-29
Abstract: 557,064. Glass manufacture. KINKER, C. C. July 29, 1941, No. 9643. Convention date, Aug. 2, 1940. [Class 56] [Also in Group XXIV] Consists in means for imparting an intermittent rotary movement to an element such as the mould-carrying table of a glassware forming machine without subjecting the moving parts to undue wear and at the same time, eliminating backlash. In Figs. 1 and 2 two tables 28 of such a machine are actuated by composite cams rotatable on a column 20 driven from an electric motor 23 through a shaft 22, 22<SP>1</SP> with safety clutch 24, and worm gearing 21, 211. The drive, according to the invention, is the same for each table. The composite cam consists of a heart-shaped cam 25 which carries a second cam 26 and an off-set cam 27. The cams 25, 27 are in a plane to engage rollers A, A' &c. on the table 28, and the cam 26 is in plane to engage rollers B, B<SP>1</SP> &c. also on the table but above and clear of the rollers A, A<SP>1</SP> &c. The_table rotates about the axis C of a supporting column 30, and each pair of rollers A, B; A<SP>1</SP>, B<SP>1</SP>, lie on a radius. The apparatus shown is designed to rotate a six-station table in stages of 60 degrees and to lock it accurately and without backlash in each of its stages, the motion from one stage to the next being first accelerated and then retarded. In Fig. 3, the centre of the composite cam is shown at X and the centre of the table at C. Opposed portions of the cams 25, 26 are arcs struck from the centre X, and when the rollers are in engagement with such circular portions no movement of the table occurs. In Fig. 3 the rollers A, B ; A<SP>1</SP>, B<SP>1</SP> are on such portions, but move off them during rotation of the cam, clockwise through the arc G and co-operate in starting the table and accelerating its movement, the roller A<SP>1</SP> preventing the table from overrunning the cam. During movement of the cam through the arc H, the roller A<SP>1</SP> contacts the face 27a of cam 27 while maintaining its contact with cam 25 and performs the double function of driving the table and preventing backlash. Further Figures of the drawing show the positions of the various parts when the cams have rotated through the remaining arcs I ... M to complete one stage, i.e. 60 degress of movement of the table. During movement through the arc M, the cam rollers A<SP>1</SP>, A<SP>2</SP> move on to the opposed circular parts of the cams and form a lock for the table holding it in a definite position. The Specification as open to inspection under Sect. 91, describes also a modification in which the tables are driven by a combination of a cam and toothed gearing. This subjectmatter does not appear in the Specification as accepted but forms the subject-matter of Specification 557,156.

Title: Improvements in or relating to wrinkle coating compositions
IPC: C09D167/08
Filed: 1942-07-14
Abstract: Resinous condensation products are made by heating an oil having a plurality of double bonds in non-conjugated position with an alcoholic solution of a basic reagent in quantity greater than stoichiometric to transform all the oil acids into soap, isolating the fatty acids therefrom and heating them with a polyhydric alcohol and a polycarboxylic acid.  The basic reagent may be a metal hydroxide, e.g. alkali metal or ammonium hydroxide, or the corresponding alcoholates, e.g. sodium or potassium <PICT:0566000/IV/1> methylate, ethylate, butylate or isoamylate. Suitable oils are cotton-seed, corn and peanut oils.  Suitable polyhydric alcohols are glycerol, polyglycerol, glycol, polyglycol, mannitol and sorbitol and the polycarboxylic acid may be phthalic anhydride, malic, maleic, fumaric, succinic, citric, tartaric, mucic and benzoylbenzoic acids or their anhydrides.  In an example, cotton-seed oil and a 20 per cent solution of potassium hydroxide in alcohol is placed in a kettle 10 and stirrer 11 is set in motion through motor 12 and gearing 13.  Steam is introduced by pipe 14. Alcohol vapour driven off through pipe 20 is condensed in condenser 21 and returned to the kettle 10 through pipe 24 and valve 25.  At the end of the reaction, valve 29 is opened and valve 25 closed so that the condensate flows through pipe 28 to a reservoir 30.  The soap is acidified, the precipitated fatty acids are separated and heated in a kettle to 400 DEG  F.  Glycerol and phthalate anhydride are added and heating continued with stirring. The mass is cooled to 350 DEG  F., and a drier, e.g. cobalt naphthenate, resinate or linoleate and a hydrocarbon diluent, such as toluol, xylol or naphtha, are added to form the wrinkling coating composition.  In one modification, the soap or the fatty acids separated therefrom are heated to 500 DEG  F. in the kettle to re-esterify the fatty acids with added glycerol or the glycerol resulting from the saponification.  In a further modification, the potassium hydroxide is used in glycerol solution and the reaction is carried out under reflux.  Specifications 547,287 and 565,563 are referred to.
