Patent GB-294498-A (GB)
Title: Method and apparatus for manufacturing seamless tubes according to the hot extrusion process
IPC: B21C23/21
Filed: 1927-03-24
Abstract: 294,498. Singer, F. March 24, 1027. Addition fo 248,972, [Class 83 (iv), Metals Working]. Tubes.-In making tubes as in the parent Specification the blank is first compressed in the container, then pierced and finally extruded, the idle stroke preferably being more rapid than the working stroke. A hot steel or iron blank a is inserted in a container b and pressed by a punch n which is carried by a slide o and operated by a cam p and roller q. A mandrel m carried by a slide l and operated by a crank g advances with the punch n and when the roller q is released by the cam p the mandrel advances alone and pierces the blank ejecting a wad s, Fig. 3. The slide l then engages the slide o and punch and mandrel advance together to extrude a tube through the die c. The quick return is obtained by using a direct current variable speed motor or a three-phase commutator motor.

Title: Improvements in or relating to the manufacture of hollow bodies and containers from artificial resins
IPC: B29C51/10
Filed: 1935-03-15
Abstract: In the method of manufacturing open hollow bodies having one or more constrictions disclosed in the parent case, the mould is lined by blowing or spraying the artificial resin composition into the mould and air is then admitted under pressure to mould the material under the requisite temperature conditions.  The moulding powder may be moistened to promote adhesion to the walls of the mould.  The method is particularly applicable to articles having very thin walls.

Filed: 1929-03-13
Abstract: 330,611. Gloster Aircraft Co., Ltd., and Saint, H. J. March 13, 1929. Steering and balancing; wheel brakes, applications of. - The wheel brakes of an aircraft are applied on either or both sides of the machine respectively by extreme lateral and foro and aft movements cf the aileron and elevator control column. A universally mounted lever 1, connected to the elevator control lever 15 by a link 14, has a lateral extension 4 coupled by a link 5 to a bell crank lever 6 which is connected by cables 10, 11 to the brakes on the two sides of the machine. Two additional cables 18, 19 extend from the brakes to the lower end of the lever 15. The cables are normally slack and the slack is taken up sufficiently to apply the brakes only when the control lever 1 is moved to extreme positions. A modification is described in which the cables 10, 11 are connected directly to the lower end of the control column 1. Hydraulically or electrically applied brakes may be used instead of the cable-actuated brakes shown.

Title: Improvements in or relating to the manufacture of cellulose derivatives and products obtainable therefrom
IPC: C08B3/22
Filed: 1926-03-26
Abstract: 275,286. Dreyfus, H. March 26, 1926. Cellulose acetates and other esters, and processes for making filaments and films from. - When manufacturing filaments, films, &c. from cellulose esters of very high viscosity characteristics, particularly such cellulose acetates as are obtained in the processes of Specifications 6463/15, 14101/15, and 207,562, the ripening or secondary treatment is prolonged beyond the normal stage, that is, in the case of cellulose acetates beyond the stage at which solubility in acetone or alcohol-benzene exists, to give products which when in solution in appropriate solvents produce solutions of substantially lower viscosity than those obtained with products of the earlier stages of ripening, while avoiding any substantial degradation of the cellulose nucleus or loss of strength and toughness in the resultant product. The solvents used for the preparation of these solution mays be different from those used with products obtained in the earlier stages, or they may consist of solvent mixtures of the same constituents but in different proportions; for example, as ripening proceeds beyond the normal point, so the cellulose acetates may be dissolved in acetone diluted with increasing proportions of water. In an example, to an acetylation mixture is added sufficient water to destroy the acetylating-agent, and the mixture allowed to stand until a product soluble in diluted acetone containing, say, 3-10 per cent of water, is obtained. Specification 20977/11 is referred to.

Class 78 (5) The voltage output from an electric tachometer generator 20, driven from the winding drum 15, is, after rectification, compared with reference voltages provided by adjustable resistances 31, 32, 33 34 by means of switches 41, 42, 43 44 adapted to be operated at predetermined parts of the wind, an indication being given or a controlling action effected if the output of the generator 20 exceeds the particular reference voltage. As shown, the comparison is made at two separated positions 50, 60 near the end of the wind, an overspeed condition at the more remote position resulting in the operation of an alarm 46, and if the condition still exists at the position nearer the end of the wind, an emergency brake 56 is applied to the winding drum 15. The output of the voltage generator may also give at the instrument 23 a continuous indication of speed of wind.

Abstract: 453,872. Refuse-consuming furnaces. LONGERT, C. L., Emberstrasse, Cologne, Germany. March 20, 1935, No. 8703. [Class 51 (i)] A plant for consuming refuse, more particularly municipal refuse, comprises an internally fired horizontal rotary drum furnace a in which the refuse is burnt, sintered, and fused and regenerators i for heating the combustion air and for storing heat during the intermittent operation of the plant. The drum is supported on frames n which house gearing for rotating the drum by means of supporting or bearing rings c. Charging and discharging are preferably effected through peripheral openings e, but may be effected through the ends after removing the frames n and tilting the drum about a transverse axis m. In operation, one of the burners provided at opposite ends of the furnace, say, the left-hand burner of Fig. 1, is ignited. Preheated combustion air enters through the left-hand regenerator i and conduit h and combustion products pass off through the regenerator at the opposite side and through a reversing valve to the chimney. After a certain time, the direction of firing is reversed. The melting is carried out discontinuously with separate charges. The burners may be fired with pulverized, liquid or gaseous fuel.

Abstract: 587,036. Battery lamps combined with current and fault detectors. CHADWICK, A. June 11, 1945, No. 8768/44. [Class 39 (ii)] [Also in Group XXXVI] A combined torch and tester for continuity or liveness of a circuit comprises a neon test lamp, battery, torch bulb and switch therefor carried within a casing, the switch comprising a part of the lamp or a separate casing therefor and test leads being wired across the switch. As shown, a tubular metallic casing 1 houses a torch bulb 4, dry battery 5 and neon test lamp 7. The lamp 7 is mounted in a transparent casing 8 carried by a cap 10 secured in the end of casing 1 by a bayonet joint so that a coil spring 3 is slightly compressed thereby producing good electrical contact between the bulb 4 and battery at 6 and between the other end of the battery and the end cap 8a of casing 8. The terminals of the neon lamp 7, visiblethrough apertures 12 in casing 1 are connected respectively to the end cap 8a and to a socket 10a. For testing a line for "liveness," a lead (not shown) connected to the socket 10a, is applied to the line by means of a test prod such as 19. glowing of the neon lamp indicating "liveness" provided the line voltage is great enough. For continuity tests leads 17, 18 secured to a spring clip 16 detachably carried by the casing 1 are used. The lead 18 is electrically connected to the clip and through it to the casing 1; the lead 17 is insulated from the clip and ends in a contact 21 projecting through a hole 13 in casing 1 to contact with the end cap 8a. A second hole 13 is provided through which the tip 14 of spring 15 may be depressed to contact the end cap 8a to light the bulb 4 when the apparatus is being used as a torch. The leads 17, 18 are thus connected across the switch 15 and continuity of any conductor to which the test prods 19, 20 are applied is indicated by lighting of bulb 4. The spring 15 may be used as a pocket clip or a separate clip may be provided. Other types of switch contact may be used in lieu of the spring 15, and the spring-on clip 16 may be replaced by other types of detachable connection, e.g., a two-pin plug and socket; or the leads 17, 18 may be permanently secured to their respective parts wrapped around the casing 1 and the whole then secured in an outer casing. The lead 18 may be dispensed with, the casing 1 being used in lieu as the contact.
