Patent GB-390224-A (GB)
Title: New or improved device for measuring the lengths of fibres or filaments
IPC: G01B5/02
Filed: 1931-10-06
Abstract: 390,224. Measures of length. SEVER, W., Armadale, King's Road, Bramhope, near Leeds. Oct. 6, 1931, No. 27685. [Class 106 (ii).] Comprises a method of and means for determining the length of a fibre or filament and consists in holding the fibre firmly at a point intermediate of its ends, gripping it loosely with holding devices at opposite sides of such point and progressing such devices towards the ends of the fibre until the latter is first released therefrom. Parallel brass rods 1, 2 are secured at the ends to steel plates 3, 4, and a firm holding device 5 is located approximately midway between the plates. Right and left-hand threaded shafts 6, 7 are located above and between the rods 1, 2 and are rotatably supported by the end-plates 3, 4 and the device 5. The carriages 10, 11 of the loose holding devices slide upon the rods 1, 2 and are normally held in engagement with the shafts 6, 7 by halfnut devices 12, 13 which are depressed against springs to release them from the shaft. The carriage 10 carries a graduated scale 14 passing through a flat eye 15 secured to the end-plate 4. The carriage 11 carries a transparent cursor 23 having a hair line over the scale 14 A finger 16 is fixed to the carriage 10 and a finger 17 hinged to it by a pin 18 the latter being pressed down by a spring 19 the effect of which may be varied by a screw 20 which when screwed right down has no effect on the finger 17 which acts by its own weight only. The finger 16 is provided with a pair of guides 21 between which the fibre may be laid and on its upper surface is provided with a rubber pad 22. The devices 11, 5 are provided with similar fingers but in the case of the device 5 the screw adjustment is dispensed with. In use, the devices 10, 11 are moved to a suitable distance from the device 5 and the upper fingers 17 are raised the fibre being carefully laid between the guides 21. The upper fingers are then allowed to grip the fibre. The devices 10, 11 are then progressed away from the device 5 by rotating the knobs 8, 9 until straightened out. The screws 20 are then adjusted until the tension is just sufficient to remove the crinkle or curl from the fibre while allowing it to slide freely between the fingers. The devices 10, 11 are progressed a little further and the upper finger of the device 5 momentarily raised to allow the fibre to align itself. The device 10 is then progressed by rotating the knob 8 until a sudden slackening of the fibre shows that the end is released. The device 11 is similarly moved until the other end of the fibre is released when the length can be directly measured on the scale 14 by the hair line on the cursor 23. In practice the instrument is calibrated by measuring the length of the fibre whose length is known or can be determined by other means. Rack-andpinion progressing gear may be employed instead of screws.

Abstract: 776,793. Tinning metal strip. LAWRENCE HOLDINGS (OVERSEAS), Ltd. Aug. 26, 1955 [Sept. 27, 1954], No. 27837/54. Class 82(2) A strip tinning apparatus in which the strip is continuously drawn through fluxing, tinning and washing baths has means to regulate the thickness of the solder coating. The strip S passes over a roller 1 into the flux bath 2 through a wiper 14 and thus put of the bath via two rollers 12, 13 mounted on levers 11 pivoted at 9 so that they can be bought into position for easy threading. The strip thus passes into an electrically heated, thermostatically controlled solder bath 15 and under an immersed roller 26, the latter having paddle members on each side to keep the solder agitated. The strip thus passes up through a shoe 16 which regulates the coating thickness, over an adjustable roller 30, into a water bath beneath roller 33 and out under a squeegee 40. The shoe 16 is pivoted about a spindle 23 so that it may be lifted from the bath by a hand wheel 28. By suitable adjustment of the top roller 30 in the slot 32 the strip can be positioned in the shoe to give an even coating to each side. The shoe (see Fig. 3) comprises a back plate 25a and a front plate 16a spaced therefrom by strips 16b. The immersed roll 26 is carried by the shoe assembly. Ribs 16j are provided on the shoe and are intended to be submerged in the solder even when the shoe is raised for threading, thus keeping it at the correct temperature for immediate coating. The top and bottom of the back and front plates are chamfered for easy entry and exit of the strip.

Title: Improvements in or relating to electric braking systems
IPC: B60L7/02
Filed: 1925-11-06
Abstract: 242,657. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Nov. 6, 1924, [Convention date]. Electric and magnetic.-Relates to brake systems for electrically propelled vehicles in which, when a trailer vehicle provided with brakes applied by the shortcircuit braking current of the motor vehicle is coupled to the motor vehicle, a resistance is connected in parallel with the trailer brake so that the short-circuit resistance may be kept as low as possible, and consists in the provision of means whereby the electric coupling between the motor and trailer vehicles can only be closed when the resistance is switched in. Each end of the motor vehicle is provided with a rotatable disc e, the spindle d of which carries a knife-switch member k co-operating with a fixed switch member q. The disc e has an aperture g adapted to register with the coupling socket c of the coupling by which the short-circuit braking current of the is conducted to the brake o on the trailer. The disc is urged by a spring f to a position in which the aperture g is out of register with the coupling socket e. When, as shown, the disc is turned to the position to permit insertion of the coupling plug h in the socket c the switch k is open and a resistance m is thus included in parallel with the trailer brake o in the short circuit of the motors during electric braking, the current flowing as indicated by the double arrows. When, however, the coupling plug h is withdrawn the switch k is opened by the spring f and the short-circuit current avoiding the resistance m flows in the direction of the single arrow through both of the switches k. to

When necessary the rods with the windings may be brought successively to the doorway in the casing and swung outwards ; a stop is arranged on the hinge to limit the outward movement. Each rod 4 consists of a wooden cylinder with an iron core, and the door 8 has a projecting portion 8' to prevent the centrifuged liquid from spurting out.
Patent GB-1120273-A (GB)
Title: Polyurethane foams
IPC: C08G18/64
Filed: 1965-07-01
Abstract: Polyurethane foams are prepared by reacting (1) the oxyalkylation product of a wood tar having a hydroxy number of 40 to 300 obtained by the thermal decomposition of wood, in the substantial absence of oxygen with an alkylene oxide having 2 to 4 carbon atoms, if desired, co-oxyalkylated with another polyether polyol, and (2) an organic polyisocyanate in the presence of a cellulating agent.  Another reactive hydrogen containing material such as a conventional polyether polyol may also be added to the reaction mixture.  Suitable wood tars are those obtained from hard woods or a resinous wood such as pine.  Halocarbons are the preferred cellulating agents, but water may also be added to the reaction mixture to produce carbon dioxide by reaction with the polyisocyanate.  A preferred polyisocyanate is a mixture of 2,4-toluene diisocyanate and 2,6-toluene diisocyanate. All of the polyisocyanate may first be reacted with a part of the polyol component to form a prepolymer which may then be reacted with additional polyol.  The reaction may be carried out in the presence of catalysts such as tertiary amines or organic salts of tin. Surfactants may also be used, e.g. condensates of ethylene oxide with a condensation product of propylene oxide with propylene glycol, products formed by the addition of propylene oxide to ethylene diamine followed by the addition of ethylene oxide, monoesters of higher fatty acids and silicone surfactants.  In an example a hardwood tar is propoxylated by reaction with propylene oxide in the presence of potassium hydroxide.  This product is then reacted with one of several organic diisocyanates in a manner indicated above. Also indicated in an example is a co-oxyalkylation product prepared by reacting a sucrose-propylene oxide adduct and a hardwood tar with propylene oxide.
