Title: Improvements in or relating to apparatus for reproducing signals recorded on tape
Inventor: BREWSTER ARTHUR EDWARD
IPC: H04L25/04
Filed: 1952-10-09
Abstract: 745,358. Code telegraphy. STANDARD TELEPHONES & CABLES, Ltd. Oct. 2,1953 [Oct. 9, 1952], No. 25322/52. Class 40 (3). Apparatus for regenerating code signal combinations of elements stored on a tape comprises a shaft carrying a sprocket wheel feeding the tape and a toothed wheel providing accurately timed impulses for each code signal element on the tape, two gate circuits primed respectively in response to mark and space signal elements on the tape and receiving simultaneously the accurately timed impulses so that a bi-stable device is triggered to one or the other of its stable positions to operate a relay to transmit the regenerated signals. As shown, a tape 22 on which signals are recorded magnetically is fed past a recording head 23 by a sprocket 21 on a shaft 20 carrying a wheel 1 which makes one revolution during a period corresponding to 24 code signal combinations. A further wheel 24 having 168 teeth, one for each signal element of the code, co-operates with the shaped end 28 of a pole-piece 27 associated with a magnet 29 to produce in a coil 26 one impulse for each tooth of the wheel 24. The impulses from the head 23 are passed via an amplifier V to a flipflop Fl, the output of which is passed to the corresponding gate GS, GM and the impulse from the coil 26 passes over a connection P to open gate GS or GM to effect operation of the bi-stable device F2 to one or the other of its conditions to energize relay pr<SP>1</SP> to transmit the corresponding mark or space signal. The wheel 24 is adjusted to produce its first timing impulse approximately 10 ms. after the beginning of the signal applied to the head 23. Rest periods between each code signal combination are produced as described in Specification 745,139.

Abstract: 1,085,140. Reciprocating pumps. L. SARRAZIN. June 16, 1965 [June 16, 1964] No. 25580/65. Heading F1A. [Also in Division F2] A lubricating pump comprises a casing 1 having an inlet 27 and a plurality of outlets 29 which respectively communicate with a plurality of inlet ducts (24), Fig. 3 (not shown), and outlet ducts 28 in the fixed seating-ring 2 of a rotary distributer 3. The distributer is rotated to bring a duct 31, which communicates with the pump cylinder, successively into register with alternate inlet and outlet ducts and the pump piston 7 is actuated by a beam member 10, arranged in a slot 4 in the distributer and a slot 8 in the piston, engaging pairs of cams on a fixed ring 11. The suction strokes of the piston 7 are effected by a lever 6 pivoting about a transverse pin 5 in the distributer slot 4 and engaging the cam-type heads of set screws in a fixed ring 15. The set screws may be adjusted axially to vary the length of stroke. To prevent inadvertent adjustment of the set screws a wire spring (19), Fig. 3, is inserted in a slot (18) in the body of each screw, the spring engaging axial slots formed the female screw threads. The distributer 3 is driven from a shaft 36 by means of a pawl and ratchet mechanism. A crank 39 on the shaft produces horizontal oscillations of a U-shaped rocker 41 by means of a plunger 40, spring-biased pawl 45 engaging a ratchet wheel 43 fixed to the distributer shaft 3'. Reverse rotation of the distributer is prevented by a coil spring at the upper end of the distributer having a loop 47' which engages a slot 48 in the ring 15. To provide lubrication of the pump mechanism an outlet duct 28 communicates via a slot 30 in the ring 2 with the casing interior. Each delivery stroke of the piston 7 takes place during one advance step of the pawl and ratchet mechanism and each suction stroke during two such steps.
Patent GB-224522-A (GB)
Title: Manufacture of b -2-oxybenzanthrone
IPC: C09B3/06
Filed: 1924-10-27
Abstract: Bz-21-Oxybenzanthrone is prepared from 11-diazo-21-oxybenzanthrone anhydride by replacing the diazo group by hydrogen.  The diazo-oxy-anhydride may be obtained by nitrating 11-acetaminobenzanthrone, saponifying, and diazotizing; the benzanthrone-21-nitro-11-diazonium salt is then converted into the diazonium hydrate (either by hydrolysis or by removing the acid radicle by means of alkali sulphate, alkali acetate, bicarbonate &c.), whereupon the diazo-oxy-benzanthrone anhydride is formed, nitrous acid being eliminated.  In an example 11-diazo-21-oxybenzanthrone anhydride is treated with stannous chloride and caustic potash solution; the 21-oxybenzanthrone obtained is purified by dissolving in alkali and reprecipitating; it yields with dimethylsulphate and alkali, a methoxy compound which, upon alkali fusion, forms a dyestuff dyeing cotton from the vat in green tints.  Specification 218,255 is referred to.

Abstract: 616,095. Cooling discharge apparatus. SHEPHERD, G. R. (Westinghouse Electric International Co.). Aug. 27, 1946, No. 25602. [Class 39 (i)] An electronic device such as an ignitron has means for automatically promoting cooling by radiation at and above a predetermined temperature. The cathode and anode cups 12, 13 which may be of " Kovar "(Registered Trade Mark) each have a metallic body 21 integral with their respective end walls 15, 20. Cylindrical collars 22, which may also be of Kovar, are each attached at one end to the electrode cup and surround the metallic body 21 leaving a peripheral air gap 23. Two sets of radiator fins 25 (see also Fig. 3, not shown) are mounted on central cores 24 having concave end-faces, said cores being threaded to fit internal threads on collars 22, permitting adjustment until there is a small predetermined air gap 26 between each concave end-face and the correspondingly convex end-surface of each body 21; a set-screw 28 locks these parts in position. The whole may be enclosed in an insulating tube 29. In operation, as the device generates heat, bodies 21, having a greater expansion than collars 22, expand until the air gap 26 closes, after which heat conduction direct to the radiators takes place. The ignitron may use cathode pools other than mercury, such as potassium, sodium, cadmium, tin, &c.

The apparatus shown in the Figure comprises a multi-stage evaporator 1, 2 and a discontinuous boiling vessel 27, the multi-stage evaporator having connected after it a continuously operating pre-concentrator 7, the juice outlet 17 of which communicates with a buffer vessel 19 in which a higher pressure may prevail than in the pre-concentrator and which is provided with temperature controlled heating means 21 for maintaining the temperature of the juice in the buffer vessel at a level above the crystallization temperature thereof. The buffer vessel may be of spherical shape, provided with a mechanical agitator 20 and/ or of double-walled construction, the 2 walls being inter-connected by one or more connecting stubs extending across the space between the walls. A space within the buffer vessel above the surface of the juice contained therein may be in open communication with the environment via a conduit 22.

In a machine for cutting notches in the edge of metal strip, the strip 18 is continuously fed over a work-table 23, and a cutting tool 43 continuously rotated about an axis parallel to the edge of the strip 18 co-operates with a notch 25 in the work-table 23 to cut the notches in the strip, the tool 43 being shaped to provide at least in part a progressive cut. Two intergeared discs 12 carrying tools 43 co-operate with notches 25, 26 in the work-table 23 to cut staggered notches on opposite sides of the strip 18 which is pulled through guides 20, 27 by continuously driven forming rolls 30 which joggle the projections between the notches by an amount equal to the thickness of the strip. Each tool 43 is pivoted on an integral spindle 45 in a disc 12 and is adjustable about its spindle 45 by a stud 48. The cutting surface 53 of the tool is machined obliquely and the leading and lagging edges are formed at such an angle that a continuously progressive cut is obtained. The forming rolls 30 each comprise forming rings 31, 32 lock-nutted on to the body of the roll, one pair of rings being longer and the other pair smaller than the corresponding roll body. The strip which may be copper is passed through a shaping die which bends it to tubular shape with the projections between the notches interlaced to form the outer conductor of a coaxial cable.
