Title: A method of producing a dyed striped pattern on a textile fabric
IPC: D06P5/12
Filed: 1952-11-13
Abstract: A dyed striped pattern on a textile fabric is produced by first applying to the moving fabric a plurality of separate streams of a freely-flowing aqueous striping solution so as to treat a plurality of spaced areas running longitudinally of the fabric, and then immediately saturating the entire area of the fabric with a second freely-flowing aqueous solution that prevents migration of the first applied solution, one of the solutions consisting of a dyestuff solution and the other solution consisting of a dyestuff solution of a different colour or a dye-resist solution. The striping solution is applied to the peripheral surfaces of a plurality of spaced rotating discs over which the fabric is caused to travel.  When a dye-resist solution is employed it may comprise water alone or a dyestuff solution with the colour omitted or an aqueous solution of sodium alginate and/or a water-soluble synthetic resin such as urea-formaldehyde and melamine-formaldehyde resins.  Specified dyestuffs are vat, direct and acid dyestuffs.  Numerous examples are given. Specification 734,542, [Group VIII], is referred to.

Title: Process for halogenating acetone
IPC: C07C49/16
Filed: 1963-07-23
Abstract: Acetone is monohalogenated with chlorine or bromine in the vapour phase by a process which comprises (a) reacting acetone vapour and halogen vapour in a molar ratio in excess of 3:1, preferably from 4 to 7:1, (b) distilling the mixture to separate hydrogen halide gas and unreacted acetone from the monohaloacetone, (c) contacting the mixture of hydrogen halide gas and unreacted acetone vapour with sufficient H2O to remove essentially all hydrogen halide as aqueous hydrogen halide solution, under conditions such that the acetone remains in the vapour state, (d) drying the acetone to a level less than 2% by wt. of H2O and (e) recycling the acetone to the vapour phase mixture of acetone and halogen.  The process may be effected by passage of the reactants from phase (a) into a fractionating column, from which the issuing acetone hydrogen halide are passed into a second column for stage (c) water scrubbing. It is preferred that the amount of water employed be at least the amount required to produce the aqueous hydrogen halide azeotrope. The examples give details of the chlorination of acetone.

Title: Improvements in or relating to television circuits
Inventor: JAMES IVANHOE JOHN PENFOUND
IPC: H04N5/18
Filed: 1958-09-18
Abstract: 928,071. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. Sept. 17, 1959 [Sept. 18, 1958], No. 29843/58. Class 40 (3). [Also in Group XL (c)] In a television amplifying channel in which monitoring signals are added during line return periods and after amplification are compared with a reference potential and employed to control the gain of the channel, the monitoring signals are applied during only some of the line return periods and restoration of the D.C. component of the signal in the channel is effected during the line return periods not provided with monitoring signals. The monitoring signals may be added during alternate line return periods. Alternatively they may be inserted in every third line period so that D.C. restoration is effected for two adjacent lines. The invention is described as applied to an amplifying channel as described in Specification 919,207 where monitoring pulses 7 are applied through a long-tail pair 8 to a mixer stage 1 at the input of the channel and the corresponding pulses are extracted from the output stage 6 by means of a switch 11 operated by the original pulses and compared with a reference potential from a gaincontrol potentiometer 14 to provide a control potential for valve 15 forming the cathode impedance of stage 1. D.C. restoration is effected by means of a switch 16 which is closed to a predetermined potential-earth as illustrated-by pulses 17 applied through long-tail pair 18. In accordance with the invention, pulses 7 and 17, which occur during line return periods, are derived from line-frequency pulses by means of a scale-of-two counter so that the pulses occur at half line frequency with pulses 17 occurring in the intervals between pulses 7. In another way of carrying out the invention, long-tail pairs 8 and 18 are each driven on one grid by line-frequency pulses and are driven on the other grids respectively by the negative and positive outputs from a scale-of-two counter driven by line-frequency pulses. The invention is applicable to a monochrome television system and a colour television system involving a plurality of simultaneous channels as described in Specification 919,207. Reference is also made to use of an additional D.C. restoration circuit operating during field return intervals.

Abstract: 617,568. Magazine gramophones. FELLINGA, G. Oct. 7, 1946, No. 29897. Convention date, March 7, 1939. [Class 40 (ii)] In a magazine gramophone of the type in which records are fed edgeways from a magazine adjacent to the turntable, means are provided for playing both sides of the records comprising an invertable magazine 51 into which the record 63 on the turntable 23 is pushed by a hook ended arm 35, and a second similar arm 36 which pushes the lowermost record 67 from the magazine 51 to the turntable 23 after the magazine 51 has been inverted, characterised in that the magazine 51 is provided with a member 61 beneath which the lowermost record 67 slides during invertion in order that it may be separated from the other records so that engagement by the hook-ended arm 36 is facilitated. When the record-changing operation is initiated, in a known manner, by the pick-up reaching the end of the record, a motor 2, which drives a shaft 12, Figs. 2 and 3, in a counterclockwise direction, is switched on, The shaft 12 is provided with arms 14, 24 and an eccentric member 37 which are shown in their initial positions in Figs. 2 and 3. During a record-changing operation, the arm 14 controls the lifting and lowering of the turntable 23 and turntable motor 21 by means of a lever 15, while the eccentric member 37, which is surrounded by a strap 38 connected to a slotted bar 39, serves to invert and return the magazine 51 through the medium of a toothed quadrant 42, and controls the movements of the pick-up arm 47 by means of a rod 46. The arm 24 controls the movements of the hook-ended arms 35, 36 by means of the slotted bar 26, lever 27 and shaft 29. Connected to lever 27 is a spring leaf-member 32 which registers with stops 33, 34 and causes the hook-ended arms 35, 36 to be withdrawn from contact with the records 63, 67 respectively after record movements have been made by them. In the initial position of the magazine 51 the records rest upon members 59 and beneath a bar 57. When the record-changing operation has commenced, the turntable is lowered, and the record 63 rests upon bearers 64, 65. The arms 35, 36 are then rotated clockwise so that the record 63 is pushed over the lugs 58 on the magazine 51 and beneath the bar 57. The magazine 51 is then inverted in a counterclockwise direction, during which the records rest against the member 61 with the exception of the lowermost record 67 which becomes separated from the other records as shown in Fig. 6. The arms 35, 36 are then moved counterclockwise so that the hookended arm 36 pushes the record 63 up the ramp 69 and the curved ends of the bearers 64, 65 to rest in a position immediately above the turntable 23, which is then re-elevated to the playing position, the pick-up arm 47 having meanwhile been restored to the initial playing position by the rod 46.

Title: Automatic self-adjusting brake attachment
IPC: F16D65/54
Filed: 1925-11-27
Abstract: 259,414. Rider, J. Nov. 27, 1925. Electric and magnetic; compensating for wear. -Relates to brakes applied by a weight or spring and released by a solenoid or electromagnet. To maintain the stroke of the plunger or armature of the magnet constant irrespective of wear of the brake shoe or lining, the plunger or armature is coupled to the brake mechanism by a friction gripping-device which becomes disengaged when the plunger returns to a predetermined point after de-energizing the magnet to release the brake. The lever J actuated by a weight I to apply the brake has secured thereto a rod A with a tapered end which passes into a cup C provided with a tapered part B. A collet D in four segments tapered to correspond with the rod A and part B rests on the end of a tube F secured to the plunger of the solenoid K. When the solenoid is de-energized and the brake applied the parts are in the position shown, the rod A being uncoupled from the tube F. If the solenoid is energized. the tube moves upwards and the collet D wedges between the part B and the end of the rod A so that the parts F, D, 0, A are coupled together and the brake is released. When the solenoid is again de-energized the downward movement of the tube F and cup C is arrested by the fixed part G but the rod A becomes uncoupled from these parts and is able to continue its downward movement until the brake is applied.
