Abstract: 770,271. Open fireplaces. HAZEL, A. C. July 23, 1952 [July 23, 1951], No. 17357/51. Class 126 An open fireplace unit comprises a metal box or casing open at the front and provided at its upper end with a body portion of upwardly tapering shape to form a funnel the reduced open upper end of which is adapted to be sealed to the chimney proper in a substantially airtight manner. The fireplace unit shown is of all metal construction and comprises five parts -(1) an ash pan 34; (2) an openfronted box 10 formed with grate supporting ledges 33 and front bar supporting flanges 14, (3) an upward tapering hood or body portion 16 fitted at its upper end with a damper 24 and formed with an arch-shaped front opening 26; (4) a chimney connecting piece 29 and (5) a grate (not shown). The upper part of box 10 and lower part of hood 16 are formed with engaging flange surfaces whilst the piece 29 fits over upstanding flanges at the top of the hood 16. According to the Provisional Specification, the open fireplace may be converted into a closed one by withdrawing the ash pan from under the grate, inverting it and placing it so inverted over the fire on the grate.

Title: Process for producing phosphorus pentasulphide having a controlled reactivity
IPC: C01B25/00
Filed: 1961-05-12
Abstract: <PICT:0923330/III/1> The reactivity of phosphorus pentasulphide, as measured by the time required for a given temperature rise in the reaction with 2-ethyl hexanol, is reduced from an initially high value by heating the sulphide at a temperature below its m.pt, e.g. up to 90 DEG C. below, for a selected time and then cooling.  The reduction in reactivity achieved depends on both the temperature and the length of time of such heating.  As shown in Fig. 1 the initial high reactivity sulphide is formed in generator 11 as a vapour and passed to condenser 14 from where it condenses and collects as a liquid in container 16.  Here the flaker drum 18 cooled to approx. 200 DEG C. delivers the solid sulphide via pipe 19 to a jacketed screw conveyor 20.  This can be controlled to give the desired temperature and, by varying the speed of the helix 22 by means of variable speed reducer 25, a desired residence time can be achieved before delivering via pipe 29 to a final cooling to ambient temperature and storage.  A sample of sulphide of lowreactivity may have its reactivity raised a controlled amount by first melting the sulphide, quenching it and then submitting it to the process of the invention.

Title: Improvements in or relating to instruments for measuring and registering the lengthsof textile or other fibres
IPC: G01B5/02

Abstract: 666,492. Counting-apparatus; measures of length. WOOL INDUSTRIES RESEARCH ASSOCIATION, ANDERSON, S. L., and PALMER, R. C. Oct. 4, 1949 [June 30, 1948], No. 17530/48. Classes 106 (i) and 106 (ii). [Also in Group IX] An instrument for measuring and registering the lengths of fibres comprises a pair of stationary gripping jaws between which a fibre can be drawn for tensioning, located at or near one end of a shaft capable of being rotated at constant speed and helically grooved to permit a tool capable of gripping one end of the fibre to be moved axially and a device associated with the stationary gripping jaws which operates when the other end of the fibre passes out of the stationary gripping jaws to stop the rotation of the shaft. One end of a fibre is held by forceps and the fibre is drawn through a guide 29 between a fixed polished hard steel jaw 13 and a similar upper jaw 14 carried by a pivoted arm 15, held wide by depressing a key 17 which is then released almost to close the jaws. When most of the fibre has been drawn through another key 18 is depressed to close the jaws and the forceps are held in contact with an axial guide 30 and a helical groove 2 in a shaft 1 driven at constant speed by an electric motor 5 through a slipping clutch, so that the forceps are carried along to the right holding the fibre under tension until its end slips through the jaws and ceases to support a platinum-tipped feeler 19 which then dips into a mercury contact 22 to close a circuit to an electromagnet 12 to put a stop 11 in the path of one of two teeth 10 on a wheel 9 of the clutch mechanism so as to prevent the shaft 1 from rotating. The forceps are then raised slightly to actuate a ratchet mechanism to lower one step a rack 24 sliding in guides 26 and so expose a number. The pitch of the helix is two units of length and the racks 24 are at unit distances apart, only alternate racks being shown, so that the numbers exposed in each counter register the number of fibres of the length-range to which the counter corresponds. The position of the wheel 9 may be adjusted with respect to the shaft 1 so that when the stop 11 engages a tooth 10 the distance of the centre of any groove measured from a point nearest the guide 30 is an exact multiple of units from the nearest point of the jaws 13, 14.

Filed: 1959-05-26
Abstract: In a method of making a shoe at least part of the upper thereof is formed from a stiffener material, and part of the stiffener material is activated whereby to render it stiffer than the remainder.  A length of double-raised woven cotton cloth is impregnated with introcellulose, dried, then coated on one side with an aqueous composition containing natural rubber latex or synthetic rubber or resin, whiting and conventional dispersing and vulcanizing ingredients to give a barrier coating, and dried. A fibrous filler, e.g. flock may be included.  A synthetic rubber adhesive comprising neoprene, a resin and chlorinated rubber is spread on to the dried barrier coating, and a room temperature isocyanate curing agent is then added.  Nylon flock fibres are sprinkled from a vibrating metal sieve over the adhesive while still wet, and the material dried. Pieces the shape of shoe uppers are then cut from the material.  The uppers are assembled with linings on their unflocked sides and assembled on lasts. They are activated at their toe and heel ends with a volatile solvent to activate the nitrocellulose impregnant, the uppers are then pulled over, and after completing the lasting and allowing time for the material to dry, the lasts are slipped and the shoes completed.  The stiffener may form part only of the upper. Specification 381,245 is referred to.

In a railway track ballast tamper having an engine (not shown) connected by a clutch 3 to change-speed gearing in turn connected by members 8, 9 to driving-wheels, the clutch being controlled by a pedal 10 and brakes (not shown) being controlled by a pedal (not shown), fluid pressure means are provided to operate levers 15, 18 against the action of springs 19, 20 whereby the clutch is engaged and the brakes released, means 24, 25 being provided for locking the levers 15, 18 whereby the brakes and clutch can be controlled by the pedals independently of the fluid-pressure means. As shown, the clutch is disengaged through a fork 5 by clockwise rotation of a shaft 4 through a link 10 from the pedal 7, the gearing being controlled from a shift lever 6 and the brakes controlled through a rod 16 in a cylinder 17. The link 10 carries a boss 12 rotatably mounted on the shaft 4 and clutchable to the shaft 4 by member 13 slidably mounted on a squaresectioned portion 14 of the shaft 4. The fluidpressure means for controlling the clutch and brakes conjointly whereby the tamper is inched comprises a servomotor including a cylinder 23 and a valve (not shown) controlled by the driver. The piston-rod 22 carries a stirrup 21 connected to the levers 15, 18 rotatably carried by the shaft 4. The locking lever 25 slidably controls the member 13 through a rod 29 and a plate 30 carrying a lug 33 so that when the lever 25 is moved in the direction of the arrow 27 the levers 15, 18 are unlatched and the member 13 is moved from engagement with the boss 12 into engagement with a boss 28 on the lever 18. Anti-clockwise movement of the levers 15, 18 when unlatched and under the action of the springs 19, 20 disengages the clutch 3 and applies the brakes, the lever 15 carrying an abutment engaging the brake cylinder rod 16. Subsequently the clutch can be engaged and the brakes released by upward movement of the rod 22 by operation of the valve associated with the cylinder 23. In a modification the levers 15, 18 are actuated through separate cylinders instead of a single cylinder 23, the separate cylinders permitting the brakes to be applied without disengaging the clutch.
