Title: Improved method of, and traverse mechanism for, winding cops on a ring frame having a lowering spindle rail
IPC: D01H1/36
Filed: 1951-06-27
Abstract: 688,446. Building cops. AKT.-GES. J. J. RIETER & CIE. June 27, 1951 [June 29, 1950], No. 15294/51. Class 120(ii) In a method of winding cops on a ring frame having a lowering spindle rail, the thread guides, on winding the cop bottom, are lowered parallel to the spindle rail and the ring rail, in the course of building the cop, is moved in a direction opposite to the movement of the spindle rail and at a reduced rate with respect thereto, such movement of the ring rail being controlled from the spindle rail. A heart cam 8 rocks a lever 10 to oscillate a compound pulley 14, 15, the portion 14 of which includes a movable cam 17, over which the chain 13 extends, and the portion 15 of which includes a cam 33 over which extends the chain 24 which oscillates the compound roller 25, 26 which, through a chain 27, vertically reciprocates the ring rail 4. The axle pin 16 of the pulley 14, 15 is flattened along its periphery and is carried by one arm 18 of a bell crank lever, pvioted at 19 to the frame, the other arm of the lever having a sliding slotted connection, at 20, to a plate 23 on the spindle rail 3. As the rail 3 descends, the pin 16 is rotated to bring the flat thereon beneath the cam 17, which forms the bottom of the cop, to allow the same to be depressed below the surface of the pulley 14 so that normal traverse may be effected. A skew portion on the peripherally-adjustable cam 33 serves for varying the traverse. The guide rail 40 is supported by rods 35 (not shown) which slide in holes in the spindle rail 3 and in cross-bars 36 (not shown). At the beginning of the wind each rod 35 is supported by a collar 39 (not shown) thereon bearing on the rail 3, but after the bottom of the cop has been formed, another collar on the rod contacts a cross-bar 36 and thereafter until the end of the wind the guide rail is maintained in that position.

Title: Methods for purifying urokinase preparations
IPC: C12N9/96
Filed: 1972-09-22
Abstract: 1411422 Purifying urokinase solutions CHOAY SA 22 Sept 1972 [24 Sept 1971 30 June 1972 (2)] 15502/75 Divided out of 1411421 Heading C3H A method of purifying an aqueous solution containing 1.5-3 mg./ml. of urokinase, foreign proteins and pyrogenic substances involves adjusting the pH of the solution to between 3 and 4.5 and its conductivity to between 15,000 and 25,000 micromhos/cm., determining, e.g. with the aid of a graph prepared from experimental results, the concentration of ammonium suplate needed for forming a precipitate of foreign proteins &c. containing only 2-5% of the total activity of the urokinase in the initial solution, adding to the solution the appropriate quantity of ammonium sulphate and collecting the supernatant. The concentration of ammonium sulphate employed should preferably correspond to a degree of saturation of the solution of from 0.25 to 0.35. The urokinase is then precipitated out with a further quantity of ammonium sulphate and the precipitate is dissolved in distilled, sterile apyrogenic water at pH 7. The initial urokinase solution may be obtained from human urine by absorbing the proteins &c. from the urine on a filtration adjuvant, re-extracting the urokinase and other adsorbed proteins &c. therefrom, salting out urokinase from the solution by adding ammonium sulphate, dissolving the resulting precipitate in a glucose solution and dialysing the latter to obtain a concentrated crudeurokinase solution of specified conductivity, two steps of fractionation using diethylaminoethyl cellulose employing in the first step solutions of pH 4-6 and conductivity 15,000- 25,000 micromhos/cm. with 15-40 g. of resin per 14 million CTA units of urokinase, and in the second step solutions of pH 6-7 and conductivity 15,000-18,000 micromhos/cm. with 30-60 g. of resin per 10 million CTA units of the enzyme, the urokinase-containing medium during the second step being diluted with quantities of water sufficient to lower the conductivity by about 1000 micromhos/cm. at each successive dilution until a conductivity of about 9000 micromhos/cm. is reached, and then absorbing the urokinase in the solution obtained by combining the effluent and the washing liquors from the resin used in the second fractionation on either carboxymethyl cellulose at a pH of about 5 and eluting the adsorbed urokinase using a phosphate buffer at pH 6.8-6.9, or kaolin at pH 6.2 and eluting the urokinase retained with a solution of ammonium chloride in 4% ammonia, followed by precipitation with ammonium sulphate and dialysis against a 0.05 M phosphate solution buffered to pH 6.2.

Title: A method of employing a rectifier in conjunction with a battery regulating switch
IPC: H02J7/00
Filed: 1941-12-04
Abstract: 553,833. Charging and discharging batteries. MARSHALL, W. J., and CATT, L. H. Dec. 4, 1941, No. 15622. [Class 38 (iv)] End cells are added to or removed from series connection with the main battery (or subsidiary sources of E.M.F. added to or removed from a main source) by a sequential operation of switches in conjunction with a rectifier which during the .change-over is connected across the end cell and prevents excess current flowing through the switch contacts. In the rudimentary form shown in Fig. 1, in order to add the cell c to the remainder, the switch b (normally closed) is opened so that the supply to the load is continued through the rectifier R in its forward direction ; the switch a is then closed thereby connecting the end cell in series and short-circuiting the rectifier across the end cell. This short-circuit is, however, harmless as the conductivity of the rectifier in the reverse direction is negligible. The short-circuit may, finally, be opened by a third switch, not shown. To remove the cell the sequence is reversed. The sequences described may be obtained by means of a single switch element with rectilinearly or rotary. contacts moving over fixed contact members to which a number of end cells are connected in conjunction with a single rectifier which is brought into use for each end cell in turn, Fig. 2 (not shown). Alternatively two ganged rotary switches may in turn serve to energize contactors which effect the same sequence, Fig. 3 (not shown).

Title: Refuse sorting process and plant
IPC: B03B5/62
Filed: 1976-04-15
Abstract: 1498767 Sorting refuse SIEBTECHNIK GmbH 15 April 1976 15691/76 Heading B2H A process for sorting refuse comprises removing the fines by screening, comminuting the refuse, separating the refuse into light and heavy fractions by a gas stream, and separating the heavy fraction into two fractions of different density by a liquid flow. After comminution, the refuse is fed into a zig-zag duct 22 through which air is drawn upwardly by a fan 7. Light material e.g. paper, fabric and light plastics, is entrained by the air stream and removed therefrom in a trap 6. Medium density material collects in a trap 28 having an inlet 26 whose crosssection is adjustable by means of a slide valve 27. Heavy material e.g. heavy plastics, bones and inorganic material, is discharged through a valve 31 and passes to a wet separator 32, Fig. 3, via a vibrating conveyor 40. Water is introduced into the separator 32 from a pipe 36 and flows upwardly through the opening 35 at the base of a tapered insert 34 as indicated by the arrows 37. The lighter material is discharged together with water via an overflow 33 and may be passed to a screen (15) and a second wet separator (16), Fig. 1 (not shown). The heavy material e.g. metal, glass and ceramics, sinks to the bottom of the separator 32, is discharged therefrom by a bucket elevator 39 and is then passed to other sorting machines for the extraction of metal and glass therefrom.

Title: Improvements in and relating to fluid controlling valves
Inventor: SHAND STANLEY GRAPES
IPC: F16K1/12
Filed: 1954-05-27
Abstract: 797,189. Valves. SAUNDERS VALVE CO., Ltd. May 25, 1955 [May 27, 1954], No. 15755/54. Class 135. In a valve for controlling high pressure fluids, two co-operating sealing members, i.e. a resilient closure member and its seating, are carried by a movable member and a piston respectively both slidable in and sealed with respect to the valve casing, the movable member being linked to mechanism actuated from outside the casing for positively separating the sealing members to open a passage from the inlet to the outlet of the valve casing and the piston being permitted a small range of movement before the mechanism is effective to separate the sealing members, such movement being effected under a spring bias acting in a direction to bring the sealing members together and take up this movement, and under the inlet pressure acting on an area at the back of the piston which when the valve is closed is greater than the area on which such pressure acts in a direction to separate the sealing members so that when the valve is closed, the inlet pressure holds it closed. As shown, a piston body 13 slidable in a sleeve 22 is operated by a rotary spindle 15 mounted in a valve body or casing 11 and having an eccentric pin 23 connected by a link 24 to the body 13. The piston body 13 has a threaded spigot 26 on which is secured by a nut 27 a resilient closure member 29 and a piston head 28. The latter with a skirt 32 slidable on the sleeve 22 and forming with the piston 13 an annular chamber 35 open to the valve inlet through passages 36, 37. The movable member comprises the parts 13, 28, 32. The closure member 29 which may be of fairly hard rubber, co-operates with a seating 38 formed at the inner end of a cupshaped recess in a piston 41 slidable in an inlet fitting 42. The piston 41 has a spigot 44 sealed in the end fitting 42 and is urged towards the valve body 11 by dished plate springs or Belleville washers 45. The cupshaped recess is connected by two arcuate passages in the body 11 to an outlet fitting 47 the passage in which is faired by a hemispherical or similar dome 48 held in place by lugs 49 and having a central vent aperture. The rotary movement of the spindle 15 is limited to about 180 degrees by a projection on a thrust plate 18 co-operating with shoulders on a fixed plate 55. In the closed position of the valve, the pin 23 is just over the dead centre so that the mechanism operates initially with a high mechanical advantage in the opening phase. The inlet pressure acts on the annular area 44a of the spigot 44 and this area is arranged to be greater than the area at the opposite end of the spigot exposed to inlet pressure when the valve is closed so that there is always a net pressure tending to hold the valve closed. Similarly the inlet pressure acting on the piston head 28 when the valve is closed is more than balanced by the total pressure in the annular chamber 35. Specification 797,190 is referred to.
