Abstract: 843,193. Cutting glass tubing. GENERAL ELECTRIC CO. Ltd. April 2, 1958 [April 8, 1957], No. 11428 /57. Class 56. In apparatus for operating on a particular region in a continuously-fed length of material, such as glass tubing emerging from a tubedrawing machine, and in which the operating member travels with the material while operating on it and is then returned to the starting position to repeat the operation, the operating member carries two clutches each arranged to clutch the member to, or declutch it from, the oppositely-moving sides of an endless band (or bands) running parallel to the material, the clutches being governed by control means which are adjustable to vary the time interval between clutching and declutching so as to vary the length of stroke of the operation. The invention is shown applied to apparatus for severing into adjustable predetermined lengths glass tubing 3 continuously fed in the direction of its length, the severing being effected, entirely or partly, by means of a ring burner 6 mounted on a carriage 1 which is alternately clutched to the upper and lower flights of a driven endless chain 7 (or alternately clutched to two oppositely moving chains). The carriage during its forward movement travels with and at the same speed as the advancing tubing, the burner surrounding an annular zone of the tubing at which severance is to take place, and the interval between the clutching and declutching of each clutch is made adjustable so as to vary the length of stroke of the carriage and hence the length of tubing severed. The actual severance may be by the melting effect of the gas burner only as in Specification 843,192, or by such melting followed either by the passage of an electric current around the heated ring as in Specification 808,284 or by thermal shock. Sprocket wheels 11, 12 engaging the chain 7 and fast on shafts 13 normally rotatable on the carriage 1 are alternately locked to the carriage by electro-magnetic clutches 14, 15 which are alternately actuated by cams 20, 19 on the carriage engaging, respectively, microswitches 18, 17 at the ends of the forward and backward strokes of the carriage. One switch energises one and de-energises the other clutch, and the other switch de-energises the one and energises the other clutch. The positions of the holders 28 of the switches may be adjusted along a rail 28 to vary the timing. Switch 18 may however be omitted and the switch 17, in addition to energising clutch 14 and de-energising 15 when operated by cam 19 may initiate operation of an electronic timing circuit which will perform the same functions as the parts 20/18.

Title: Improvements in or relating to gas-liquid or gas-solid chromatography
Inventor: HAMLIN ANTHONY GEORGE
IPC: G01N30/66
Filed: 1960-03-31
Abstract: <PICT:0924094/III/1> <PICT:0924094/III/2> <PICT:0924094/III/3> <PICT:0924094/III/4> In a gas chromatograph comprising a gas chromatographic column (3) with a solid or solid-supported liquid absorbent, a katharometer (5) having chambers (12, 13) with electrical heating elements for a carrier gas stream and the emergent gas stream, and a comparator circuit, the katharometer is housed in a chamber formed in a heat-conductive mass (1) having thermostatically-controlled heating means (6) encased therein.  As shown in Fig. 1, to which the above numerals relate, the chromatographic column 3 and a reference column 2 are coiled around a sheath 1b between which and an inner cylinder 1a (which together form the heat-conductive mass) is an insulated heating coil 6 and a bare wire coil 6a to prevent inductive disturbances.  A thermostat 8 is provided in cylinder 1a, close to the heating element.  Gas to be analysed enters column 3 at 39 and passes via end 30 and capillary tubes 30a, 31 into the sensing chamber 13 of the katharometer, while the reference gas similarly enters chamber 12.  The gases thereafter enter cross bores 17, 16 and are withdrawn through common outlet 32. The assembly is surrounded by a cylindrical casing 33 having a base 35 and lid 34 and the unoccupied space is packed with glass wool.  In Fig. 5 is shown a flow sheet for the apparatus: carrier gas enters at 52, is dried, if necessary, in tube 54 and passes to a buffer volume 60 whence a reference gas stream passes to column 2 and the katharometer H and a part is taken through line 60a and column 3. Valves 89, 87 and 88 provide for alternative flow of the carrier gas directly to column 3 or via sample volume 69. Valves 85, 86 provide for the filling of volume 69 from gas pipeline 66 for the gas to be analysed.  The valves are operated by means of device 79 (see Fig. 4).  Compressed air is admitted to opening 84 and operates the above mentioned valves, which correspond to lines 89b, 87b, 88b, 85b and 86b respectively of device 79.  Piston 81 driven by motor 82 opens the above mentioned lines to programme the taking of a sample.  The result of the analysis is recorded as a chromatogram at R using an amplifier A for the output of a Wheatstone bridge aircuit.  The apparatus may be used to purify UF vapours at sub-atmospheric pressure and elevated temperature using a column packed with ground solid polytrifluorochloroethane supporting polytrifluoro-chloroethylene oil.

Title: Process for the production of lead glazes
IPC: G03C7/04
Filed: 1933-04-20
Abstract: 410,602. Glazes. HARKORT, H. J., 10, Landoltstrasse, Zurich, Switzerland.- (Assignee of Vassel, R. ; 32, Haupstrasse, Tegel, Berlin.) April 20, 1933, Nos. 11562 and 11563. Convention dates, April 25, 1932 and Nov. 28, 1932. [Class 56.] A method of producing lead glaze for ceramic ware consists in using bye-products or waste, of the type normally obtained in the manufacture and use of electric accumulators, for the introduction of the lead content. The material, which consists of lead more or less completely oxidized, occurs as waste in the production of accumulator plates or as the precipitate which is deposited during the operation of the accumulators. The content of lead in the material available is determined, and the quantity to be added to the glaze batch is determined accordingly. Any metallic lead present in the material can be oxidized during the process of fritting by the addition of a suitable oxidizing agent or by providing an oxidizing atmosphere. A suitable batch is given in the Specification.

Patent GB-1177212-A (GB)
Title: Improvements in and relating to Winding Mechanisms for Yarn Processing Machines
Inventor: SCRAGG FREDERICK
IPC: B65H67/04
Filed: 1966-04-17
Abstract: 1,177,212. Doffing and donning bobbins. ERNEST SCRAGG & SONS Ltd. 14 April, 1967 [17 April, 1966], No. 11672/66. Heading D1J. A winding machine comprises a frame 11 for supporting the former F during the winding on of yarn and is so constructed and operated during doffing that the frame is adjusted to release a wound package P and is displaced from the winding position (as shown in Fig. 1) to a former pick-up position in which the frame is adjusted to pick up an empty former F' and that the frame is then returned in the reverse direction of movement to the winding position with the empty former. As shown, the package P, grows in size during winding and rotates the frame arms 11, 11' and 17, 17' anticlockwise to position 17a (Fig. 1). When the package is fully wound cam 39 is rotated by gear 49 acting via a step up ratio gears 45 and 33 and teeth and pawls 37. The rotation of cam 39 moves lever 53 clockwise (Fig. 2) and this causes arm 17 to release the package. The package then falls to a central conveyor (to the left hand side of Fig. 1) and the trailing unwound yarn is cut. The cut end is thus left draped over driving drum R ready to be wrapped up by the next empty bobbin, see Fig. 7 (not shown). An air suction pipe can hold the cut end over the drum R. The frame is displaced when a boss 52 carried on gear 49 (which rotates during package release) abuts with the magnet 50. This magnet is carried on a U-shaped frame 13 which rigidly interconnects the former gripping arms 11, 11' and 17, 17'. The movement of boss 52 thus rotates the U-shaped frame upwards towards the empty formers F'. The empty former F' is picked up near the end of upward movement of the frame. A cam plate 61 defects the lever 53 back to the full line position shown in Fig. 2 and thus causes the fore-arm 17 to grip an empty former F'. The frame is returned to the winding position when the direction of rotation of gear 49 is reversed (clockwise). Due to the magnetic attraction between boss 52 on the gear 49 and the U-shaped frame 13, the latter moves the former-carrying frame 11, 11', 17, 17' back to the winding position. During this movement the gear 33 over-runs the formerreleasing cam 39 by means of the pawl 37. Gear 49, which controls the doffing-donning sequence, rotates after a pre-determined time or on attainment of a certain package size or after winding a predetermined quantity of yarn. The gear 49 is rotated 180‹ during each of the doffing and donning steps by an arm (97) Fig. 3 (not shown). Arm (97) is moved by connecting it to a rocker 65 by an electrically actuated clutch, see Fig. 4 (not shown). The clutch can be engaged only when the rocker is at the extreme of its movement and it automatically remains engaged whilst gear 49 is rotated in both directions.

Title: Improvements in or relating to the esterification of paper
IPC: D21H17/14
Filed: 1937-04-23
Abstract: The tensile strength of paper when in wet condition is increased by treating the paper with an esterifying agent so as to form an ester of cellulose with a carboxylic acid containing 2-5 carbon atoms, the temperature of treatment being greater than 60 DEG  C., the quantity of esterifying agent being capable of fully esterifying the paper, and the duration of the treatment being at least 5 minutes but limited so that the surface layers only of the fibres constituting the paper are esterified.  The esterification treatment is not preceded by any treatment with carboxylic acid. In an example, paper strips are immersed in a solution containing acetic acid, acetic anhydride, toluene, and zinc chloride, at a temperature of 100-120 DEG  C. for 5-20 minutes.  Petrol, benzine, benzene, carbon tetrachloride, or other diluent may be used instead of toluene. Propionic, butyric or valeric esters of cellulose, instead of cellulose acetate, may be formed on the paper.

Abstract: 716,739. Lever load handling machine. SAHLIN, H. May 8, 1952, (Aug. 30, 1951.] No. 11694/52. Class 78 (3). [Also in Group XXII] Work handling apparatus for a stamping or other press comprises a frame B, Fig. I, fixed adjacent the press 10, a guide 39 pivoted thereto at 29, a slide 38 travelling along the guide towards and from the press, a work gripper 53 on the slide and cam means 63, 65 on the frame and slide which causes the guide to tilt about its pivot when the slide travels. This may be affected by fluid pressure controlled in timed relation by the press. Adjustably secured on the frame member 15 by a clamp 19 is a structure comprising a plate 18, carrying a housing 24 for the electrical and pneumatic control mechanism and the cam 63, and two spaced brackets 27 between which is pivoted, at 29, a block 31 carrying the guide 39 and a cylinder 32 which moves the slide 38. The press drives a shaft 70 having cams to operate switches 68; when the work 12 is ready to be removed, to admit air pressure to the pipe 75a and open to exhaust the pipe 74, the apparatus being in the normal position shown. The pipe 73a supplies the right hand end of the cylinder 32 through a port 78, Fig. 6, so that the piston 34 and slide 38 move to the left slowly until a stub 75 is withdrawn from a recess 76 and uncovers the main port 77. The pipe also supplies the left hand end of a cylinder 48, adjustably mounted on the slide 38, to force rapidly to the right its piston rod 51 and a slide 53 having teeth 54 to engage the upper face of the work 12 and a pivoted chisel 59, which passes under the edge of the work and, when its tail 57a, Fig. 2, engages a stop 55, swings into work holding position X shown in broken-lines just before the rapid movement of the slide 38 begins. Then, as the slide 38 and the parts carried thereby move to the left, a roller 65 on said slide engages the cam 63 thus tilting the guide 39 &c., to move the work successively into the positions Y and Z. At the end of its stroke the slide 38 operates a switch 79 thereby reversing the function of the pipes 73a, 74 to cause the work holding jaws to open and the slide 38 &c., to return to normal position. There may be a delayed action device as shown in Fig. 6 to ensure that the work is released before the slide 38 returns rapidly. In a modification a device for pushing a fresh blank between the dies is operated by a pneumatic cylinder connected by flexible tubing to the the pipes 73a, 74.
