Patent GB-631141-A (GB)
Title: Treatment of wool with chlorine compounds
IPC: D06M11/30
Filed: 1947-06-24
Abstract: The tendency of textile materials consisting wholly or partly of wool to shrink is reduced by immersing the materials in an aqueous solution containing one or more chloramides or chlorsulphonamides which do not yield chloramines in cold acid solutions, and having a pH not greater than 2 and a chloride ion concentration greater than 0.3 N.  Compounds of the general formul  <FORM:0631141/IV (c)/1> where R is an amino, alkyl, or aryl radical, R1 and R11 are alkyl or aryl radicals, R111 is an alkylene radical, and R1111 is an aryl or hydroxyl radical, may be used.  Dichloramides or dichlorsulphonamides may be used provided they do not hydrolyze to chloramines.  The chloramide may be N-monochlor-urea, N-chloroacetamide, N-chlorosuccinimide, or N.N1-dichlorobiuret.  The chlorsulphonamide may be N-chlorosulphamic acid, N-dichloro-toluene sulphonamide, or the sodium derivative of p-toluene-sulpho-chloramide (Chloramine T). The acidity of the solution may be due to the presence of sulphuric, nitric, phosphoric, or hydrochloric acid.  In the latter case the addition of further chloride ions may not be necessary.  The solution may contain calcium, magnesium, potassium, or sodium chloride.  The presence of the chloride ions enables smaller proportions of the organic compounds of chlorine to be used, e.g. amounts equivalent to 2-4 per cent of available chlorine.  The N-chloro compound may be formed in the treating solution by mixing the appropriate amide and hypochlorite or chlorine in the aqueous solution.  In examples, knitted wool fabrics are immersed for 40 minutes at 40 DEG  C. in aqueous solutions containing 0.5 per cent of sulphuric acid, sodium chloride in concentrations of 3-10 grams per 100 m.l., and N-monochlorourea in amounts equivalent to 3-8 per cent of available chlorine based on the weight of wool.  Specifications 482,656 and 595,518 are referred to.  The Provisional Specification refers also to the use of N-chlorostearamide, preferably in solution in an organic solvent containing dissolved hydrochloric acid.

Title: Improvements in or relating to severing means, adapted for severing tape applied to bag mouths in bag closing machines
IPC: B65B61/06
Filed: 1941-12-30
Abstract: 553,008. Cutting and severing tape. BAGPAK, Inc. Dec. 30, 1941, No. 16784. Convention date, Oct. 1. [Class 31 (i)] Relates to mechanism for closing the mouth of a filled bag by a line of stitching, and sealing the closure by applying a folded adhesive tape. According to the invention, the tape is severed, after it has been applied to a bag, by an oscillatable blade which is actuated by an electromagnet and devices controlled by a cam. The tape is applied to a succession of bags as they are carried through a closing machine, which may be of the type described in Specification 415,279, [Group VII]. After the application of the tape, the mouth of a bag C, Fig. 4, travels through a channel 6, and the front end of this channel is provided with a shearing anvil 7, Fig. 9, across which a depending shearing-blade 9 is oscillated periodically to cut the tape between successive bags. The blade is attached to a shaft 8 to which a tilting-bar 13, Fig. 4, is also attached. Above the bar 13 is a lever 21 which is attached to a shaft 18 and is rocked periodically by an electromagnet 26, the lever normally being held in its raised position by a spring. Crossed arms 36, 37 are pivoted on the lever 21 and their lower ends are drawn together by a spring 53. The upper ends of the levers are provided with rollers 44 which embrace cam surfaces 50 formed on the sides of a pendant bar 49 pivoted at its upper end to the casing. The lower ends of the bars 36, 37 terminate in slots 43 each adapted to engage a stud 14 on the ends of the bar 13. In use, when the electromagnet is energized. the arms 37, 38 are drawn downwards and one of the slots 43 engages a stud 14 thus tilting the bar 13 and causing the cutter 9 to sever the tape. The engagement of a slot 43 with a pin 14 causes the upper ends of the bars 36, 37 to move the came 49 to one side, and this movement together with the separation of the ends of the bars by the cam surfaces 50, moves the disengaged slot 43 clear of the rising pin 14. Operation of the electromagnet is controlled by an arm 59 which makes contact with the bags as they move through the machine.

Inventor: CASS WILFRED RICHARD
IPC: B23K3/06
Filed: 1955-06-14
Abstract: 833,333. Making printed circuits; soldering. PYE Ltd. June 14, 1956 [June 14, 1955], No. 17085/55. Classes 83 (2) and 83 (4). In applying solder to a printed circuit on one face of an insulating plate, the plate is curved before or after applying the circuit and is then moved with the circuit lowermost over the surface of a bath of molten solder in an arcuate path, the radius of which is substantially equal to the radius of curvature of the plate so that the underface of the plate or a surface applied thereto touches the solder only along a line transverse to the path of movement of the plate at any one time. A plate 1 of phenolic laminate has a printed circuit 2 in copper &c. applied to one face 3 by printing, stencilling, spraying, &c. and is curved before or after application of the circuit. Resistors and capacitors are mounted on the surface remote from the circuit with their leads 8 through holes 4 in the plate and circuit and the leads are clenched over at 8a. The plate is secured by turn buttons, circuit downwards in an aluminium cradle 9 suspended by ties 10 from a bar 11 to swing in a framework 12 above a solder bath 14. An electric motor 13 is mounted at the top of the frame and through members 24 moves the cradle back and forth. The areas to be soldered are fluxed before the base is fitted in the cradle and at the end of a swing from the position shown in Fig. 3 during which the base touches the solder the plate is sprayed by nozzles 15, 16 on a gun fed with flux from a reservoir 17. Stainless steel blades 19 on the cradle clean the solder surface and a plate on cradle coated with flux coats the solder. After passing over the nozzles the cradle hits a stop, e.g. a hook which holds the cradle stationary, e.g. for half a minute, and then releases it when the cradle swings across the solder for a second time, being hooked at the end of the swing. Solder is automatically supplied to the bath when the level falls and the pendulum is vibrated by a vibrator 21 energized by 50-cycle alternating current. The parts of the circuit other than the joints may be coated with shellac or a removable stainless steel mask may be clamped to the base.

Classes 79(2) and 79(5) [Also in Group XXX] A railway track packing machine has means responsive to the carriage movement relative to fixed track elements to control the step-by-step movement of the carriage along the track between successive working positions. The carriage 1 is driven by one set of wheels through a shaft 4 and gearing 5 and is braked on another set of wheels by a brake 8. A packing tool carriage 3 vertically slidable on two columns 40, 41 carries an eccentric shaft 42 which imparts a vibratory movement to the packing tools 43, 44 and a pivotally mounted lever 21 outwardly biased against a stop 24 by a spring 22 and arranged to tilt a bell-crank 19 to depress a piston 18 only when the carriage 3 is moved upwards. A lever 9, mounted on a slide 10 in turn adjustably mounted on a bracket 11 by a screw 12, depresses a piston 14 when engaging a rail fastening or the like on a sleeper 19. The machine operates in the following manner. Starting from a position in which the control levers 31 and 33 are in the positions II<SP>1</SP> and II<SP>11</SP> shown in Fig. 1 and the machine is in the position II the lever 9, as the machine moves forward, engages the rail fastening 34 and depresses the piston 14 to the position I to transmit hydraulic pressure through a flexible conduit 15 and a conduit 16 to a cylinder 26. The piston 27 in the cylinder 26 is moved forwards to displace a lever 33 to a position 1<SP>11</SP> to disengage the clutch 7 and a lever 31 to a position 1<SP>1</SP> to apply the brake 8 so that the machine comes to rest after a braking distance "S" with the packing tools 43, 44 located in the correct position to tamp a sleeper 19. The forward movement of the piston 27 transmits hydraulic pressure through a conduit 25 to a cylinder 17 to move a piston 18 outwards to tilt the bell crank 19. The carriage 3 is now moved downwards to tamp the sleeper 19 but on moving downwards the lever 21 does not move the crank 19. After tamping has been completed the carriage 3 is raised and the lever 21 tilts the crank 19 to depress the piston 18 which causes the piston 27 to move rearwards to disengage the brake 8 and to engage the clutch 7 and thereafter the operation is repeated as described. The brake and clutch controls can also be arranged to respond electromagnetically or photo-electrically to movement of the carriage relative to the fixed track elements.
