Patent GB-1009482-A (GB)
Title: Maximum demand meter
Inventor: THOMAS EVAN JAMES
IPC: G01D4/10
Filed: 1963-03-04
Abstract: 1,009,482. Counting apparatus. LANDIS & GYR Ltd. March 4, 1964 [March 4, 1963], No. 8569/63. Heading G4D. [Also in Division G1] A device which drives a maximum demand indicator synchronously with an instantaneous demand indicator when the instantaneous demand reaches the value which the maximum demand indicator registers is provided with a set of discs 14 which rotate to drive the maximum demand indicator and which are so movable as a whole along a shaft axis between two positions that in one position all the discs are locked against rotation whereby only the instantaneous demand indicator is driven by movement of a train of gears 8 actuated in jump-type motion corresponding to the instantaneous demand and that in the other position each disc rotates in engagement with its adjacent gear of the train of gears 8 whereby the maximum demand indicator is driven synchronously with the instantaneous demand indicator. The gears 8 and discs 14 are provided with heart cams 18 so that they and therefore their corresponding indicators may be set to zero by suitably depressing resetting levers 40, 42. With the gears and discs in the zero position, the shaft 4 carrying the discs 14 is spring biased so that pins 34 each projecting from one face of each disc 14 engage in apertures 32 in the gears 8. The train of gears which is mounted on the shaft 4 but prevented from moving along the shaft axis is driven through pinions 10, 22 by a gear 20 attached to the shaft and driven step-by-step in accordance with the instantaneous demand. The engaged position of the shaft ensures that rotation of the driving gear 20 drives a clutch gear 24 connected to the maximum demand indicator so that it registers the same as the instantaneous demand indicator. At the end of a suitable time interval the lever 40 is depressed to move the discs out of engagement with the gears and to reset the gear train at zero. On releasing the lever, the pins 34 are no longer aligned with the apertures in the gears and the clutch gear 24 is no longer in contact with the driving gear 20. The discs 14 are held in their disengaged position by detents 38 mounted on an auxiliary shaft 36 (Fig. 3, not shown) to prevent their further rotation and thus alteration of the maximum demand indicator. Only when the instantaneous demand corresponds to the value shown on the maximum demand indicator will the discs engage with the gears and both indicators register the same value as well as the same increases.

Title: Improvements in or relating to the treatment of artificial silk threads and filaments
IPC: D01D10/04
Filed: 1928-03-22
Abstract: 320,025. Brandwood, J. March 22, 1928. Apparatus for making filaments. - Artificial silk threads as they come from the spinner, either in the form of a cake or upon a bobbin, are woundon a perforated spool into a soft resilient package with an open-wind and are then treated with fluids, for example washing, desulphurising, bleaching, dyeing or other liquids, by spraying the fluids on to the inner or outer face of the package and simultaneously drawing the liquid radially through the package by suction regulated so that the liquid does not accumulate within or upon the face of the package. The threads may thus be subjected to all necessary fluid treatments including treatments with air or gases and then after final drying may be pirned or otherwise wound into the form in which the threads are to be used. In the form of apparatus shown in Fig. 1, the perforated tubular spool 9 carrying the open-wind thread package x is seated on the central member 11, connected with a vacuum pump through pipe. 13, and is surrounded by a hollow casing 16, the inner surface of which is perforated over the whole of its surface, so that the treatment fluid can be forced by a pump or by gravity from pipe 17 on to the outer coils of the package x in the form of a spray. The fluid is drawn through the package immediately in a. radial direction. In order to ensure even treatment of the threads particularly with dye liquor, it is essential that the package should be sprayed over the whole of its surface. In the form of apparatus shown in Fig. 3, the fluid is sprayed through a fixed spray pipe 18, comprising a hollow casing of arcuate form, and the tubular spool 9 is slowly rotated so that all parts of the outer face of the package x may be treated with the spray. In the apparatus shown in Fig. 5, the suction is applied to the outer face of the package x through the chamber 23, formed by a metal casing and connected through pipe 32 with a vacuum, and the fluid is sprayed upon the inner face of the perforated tubular spool 9 through a central spray pipe 28. Any parts of the apparatus may be made of non-corrodible metal or cased with such a metal or alloy or may be made of or cased with ebonite or analogous material. Specification 280,519 is referred to.

IPC: F41B7/00
Filed: 1933-03-22
Abstract: 416,932. Toy projectors. SCOTT, R. W., 19, Manor Road, Beckenham, Kent, and GUITERMAN & CO., Ltd., S., 35, Aldermanbury, London. March 22, 1933, No. 8687. [Class 132 (iii).] A toy firearm comprises a stock portion formed of fixed and detachable sides, and a barrel clamped between the sides, internal ribs on said sides coacting to form a magazine whence pellets are fed through an aperture in the barrel into the bore thereof to be fired bv a spring operated plunger controlled by a rotary trigger member. Rotation of the handle 26 causes rotation of the single or many armed lever 28 for its hooked portions 27 to engage with the finger 21 on the spring controlled rod 18 to withdraw it and allow a pellet to fall through the outlet 15 of the magazine 13, having inlet 14, and through an aperture 29 of the barrel 16. The pellet is held by the constriction 17 and is prevented from falling out of the barrel when it is tilted by means of a spring 30 passing around the outside of the barrel with each end 32 passing through one of a series of holes 31 to retain the pellet in position. Continued rotation of the handle 26 causes the hooked portion 27 to become disengaged from the finger 21 for the rod 18 to be released to fire the pellet. The ends 32 of the spring are not of sufficient thickness to affect the firing of the pellets and there is only sufficient space between the ends 32 of the spring and the constriction 17 to admit a single pellet at a time. The rod 18 in its forward unretracted position covers the aperture 29 in the barrel 16. The stock of the gun comprises fixed and detachable portions in one or more pieces with flanges 10 and ribs 11 and 12 forming a magazine, the barrel 16 being clamped between the sides and held against longitudinal displacement by the rib 12 engaging the constriction 17 and against rotation by a projection engaging an aperture in the barrel. The fixed portion of the stock is provided with a laying handle 4 and a lug 5 horizontally pivoted at 6 on a vertical spindle 7 pivotally mounted on a conical pillar 8 mounted on a base plate 9.

[Class 69 (ii)] [Also in Group IX] Hydraulic means are used to apply pressure, which may be varied, to sized and other warps of jute &c. whilst being wound on a beam. The pressure-applying roller 31 is supported by rollers 29, 30 carried by levers 27 on a shaft 24 furnished with weighted arms 33 and with a hollow boss 36 with slotted extensions receiving slide blocks 37 on a cross peg 38 on the extension 21a of a hydraulic ram. This fits in a pressure chamber 18 fitted with packing and a gland 23 and communicates by a pipe 42 with one outlet of a three-way valve the inlet of which communicates with a mains supply, whilst the other outlet communicates with an exhaust pipe. A pipe 44 leads from this to the chamber and is equipped with a pressure gauge and a spring- loaded pressure valve. The method of using the apparatus to first apply and then release and afterwards reapply pressure is described, a handle 39 being used to turn the shaft 24 to push the ram inwards and expel pressure fluid from the chamber 18 when required. An additional valve may be provided in. the main line and a pressure in excess of the mains pressure may be built up behind the ram. Two or more rams may be used. Two pressure rollers fulcrumed in shafts coupled together and acting on the front and rear of the beam respectively may be used. The warp 16 passes to the beam between draw and nip rollers over measuring and tensioning rollers 14, 15. In a modification described, the pressure chamber communicates through a twoway valve with a hydraulic accumulator and with a vertical pipe furnished with a piston-like rod. The pipe serves as an exhaust cylinder to receive fluid expelled temporarily from the pressure chamber. According to the first Provisional Specification, the pressure may be applied from above.

Patent GB-701438-A (GB)
Title: Improvements in and relating to the production of phenols
Inventor: COWIE CHARLES THOMSON YOUNG
Filed: 1950-04-11
Abstract: A process for the production of 3-methyl-4, 6-di-tertiary butyl phenol and 4-methyl-2, 6-di-tertiary butyl phenol comprises bringing gaseous isobutene into contact with mixtures comprising substantially meta and para cresols in the presence of a phenol sulphonic acid as alkylation catalyst, the temperature being maintained in the range 20 DEG  to 50 DEG C. and thereafter separating from the reaction mixture the desired phenol or phenols.  The catalyst may be a mixture of m- and p-cresol sulphonic acids.  It may be used in amount up to 20 per cent. of the total weight of phenols initially present.  The reaction mixture may be treated to effect the separation by washing with dilute aqueous alkali to remove, e.g. 2:5-xylenol and 2:5-dimethyl 4-tertbutyl phenol, followed by fractional distillation.  Individual separated phenols may be debutylated by heating with a catalyst, e.g. sulphuric acid, oleum, a sulphonic acid or a Friedel-Crafts catalyst, and the process may thus be used in the separation of m- and p-cresols.  The isobutene gas may be pure, e.g. as obtained from iso- or ter-butanol, or may be a C4 cut of gases from a process for obtaining motor spirit from coal or creosote oil or from petroleum cracking.  The cresol mixtures may contain 2:4- and 2:5-xylenols.  In examples (2) a cresylic acid containing m-cresol, p-cresol, phenol, o-cresol, 2:4 and 2:5-xylenols and higher boiling tar acids is reacted at 40 DEG C. with a butylating gas containing isobutene to give a mixture of 4-methyl, 2:6-di-tertiary butyl phenol, 3-methyl-4:6-di-tertiary butyl phenol and a mono-butylated fraction containing 2:4-dimethyl-6-tertiary butyl phenol, 3-methyl-6-tertiary butyl phenol, 4-methyl-2-tertiary butyl phenol.  These products are separated by fractionation and in example (3) the 3-methyl-4, 6-di-tertiary butyl phenol is heated at 150 DEG  to 200 DEG C. to give m-cresol.  For comparison, in example (1) a process similar to example (2) is carried out at 70 DEG C.  The Provisional Specification specifies as additional alkylation catalysts sulphuric acid, oleum, an organic acid or a Friedel-Crafts catalyst such as a metal halide, or an alkane sulphonic acid such as ethyl sulphonic acid.  Specifications 584,371 and 589,070 are referred to.

Abstract: 805,641. Forming sliver rolls. FRASER & SONS, Ltd., D. March 14, 1957 [March 22, 1956], No. 8951/56. Class 120(1) In a machine for winding rolls of jute, &c. sliver, of the type in which the roll is wound on a centre and is rotated by frictional contact with one or more driving rollers, at least one freely rotatable member is located adjacent to an end of the roll being wound and adapted to bear on a part only of the said roll end, the member being rotatable about an axis different from that of the roll centre. As shown, Fig. 2, a sliver roll 1, wound on an arbor 2 by driving rollers 4, 5, is supported at one side by a non-rotatable cheek plate 6 and at the other side by a freely rotatable disc 7 the axis of which is inclined to the horizontal so that a part only of the disc face bears on the roll. Disc 7 is mounted on an arm 8 pivoted on brackets 9 on the machine frame. Operation of a crank 13 acts through a linkage 12, 11 to move arm 8 towards or away from the roll. In a modification, Fig. 4, disc 7 is replaced by two cylinders 14 the axies of which are so inclined to the vertical that the lower end only of each cylinder bears on the roll. Disc 7 and cylinders 14 are rotated by the roll and prevent lateral spread of the sliver while exerting low frictional restraint on the roll.

Abstract: 540,622. Screw-and-nut gearing. GENERAL ELECTRIC CO., Ltd., and JONES, L. M. May 22, 1940, No. 9081. [Class 80 (iii)] [Also in Group XXXVII] In a motor-driven electric regulator comprising a number of fixed contact members in a row and a moving contact member actuated by the motor to contact with any of the fixed members, means are provided for disengaging screw-and-nut members which actuate the moving contact after a limit of its travel has been reached. A threaded shaft 1 rotated by an electric motor is engaged by a nut 2 held in a non- rotatable carrier 3 which is guided to move longitudinally by bars 18, 19. This carrier has movable contacts 4 ... 7 which cooperate with fixed contacts 8 ... 11. The nut is held in the carrier by end caps 12, 13 and is normally coupled to the carrier by two spring-pressed pawls 14, 15 one pawl being operative for one direction of rotation of the shaft. When the carrier 3 reaches either limit of its travel, the pawl operatively connecting nut and carrier for this direction of rotation of the shaft, is released. The pawls engage notches 16, 17 in the nut and when the carrier reaches a limit of travel, determined by a stop 23, one of two spring-pressed push rods 20, 21 mounted in the carrier engages the stop and pushes the respective pawl out of engagement with the notches, the nut then being free to rotate with the shaft. To ensure this rotation, the shaft 1 is provided with a sleeve 25 with teeth 27 adapted to engage a pin on the nut and rotate it. The sleeve 25, of which one is provided at each stop, is screwed to the shaft by a screw 31 engaging a keyway 32 therein.
