Title: Improvements in or relating to apparatus for trimming brushes
Inventor: MARKS THEODORE
IPC: A46D9/02
Filed: 1961-11-03
Abstract: 941,535. Shearing. AMERICAN TECHNICAL MACHINERY CO. Inc. Nov. 3, 1961, No. 39486/61. Heading B3W. [Also in Division A4] An apparatus for trimming brushes comprises a tube through which a brush may be fed, a rotary member coaxial with and rotatable relative to said tube, a rotary cutter mounted for rotation on the rotary member about an axis off-set from the axis of the rotary member and means for rotating the rotary member and the rotary cutter. The apparatus includes front and rear supports stands 15 and 16 respectively, a sleeve 20 forming part of the front stand and a rotary sleeve 35 mounted in the sleeve 20 by bearings 30. The rotary sleeve 35 extends beyond sleeve 20 and has mounted on its inner end 43 a main plate 50. In the rear surface of the plate 50 are opposed similar recesses 60 and a radial slot 67. In each recess 60 is received a plate 90 which is retained by screws 103 passing through slots 102 in extensions of the plate and into tapped holes in the plate 50. In each plate 90 is a central bore containing a ball bearing 111 supporting a shaft 112. The rear end of each shaft 112 is supported in a ball bearing 127 mounted in a plate 120, which is secured to the plate 90 by screws which enter tapped holes 108 and is spaced therefrom by parallel bars. Mounted on and keyed to the portion of each shaft 112 between the plates 90 and 120 is a milling cutter 130, and mounted on the front end of each shaft is a pulley 133 which is engaged by a belt 85. The belt tension is adjusted by an idler pulley 141 movable along the slot 67. The main plate 50 is driven by a pulley 75 keyed to the rotary sleeve 35 and itself driven by a belt 77. Also mounted on the rotary sleeve 35 are the inner races 78 of roller bearings 79 to the outer races 79 of which are fixed a pair of cutter drive pulleys 81, 82 which rotate as a unit. The pulley 81 is driven by a belt 83 at a greater speed than the pulley 75. The pulley 82 is engaged by the belt 85 and drives the cutters 130 through the pulleys 133. Extending through the rotary sleeve 35 is a fixed bushing 70, the front end of which is held centrally in a member 27 secured to the sleeve 20 and the rear end of which passes loosely through the main plate 50. Adjustably mounted on each block 90 is a cutter blade 160 which co-operates with the rotary cutter to cause a shearing action on the bristles of a brush fed through the fixed bushing 70.

Title: Improvements in or relating to textile sizing machines
IPC: D06B23/26
Filed: 1965-09-16
Abstract: 1,094,710. Textile treating apparatus. LEESONA HOLT Ltd. and G. LEE. Sept. 16, 1965, No. 39516/65. Heading D1L. In a yarn sizing machine, the pressure between a pair of squeeze rollers between which the yarn passes is automatically controlled dependent upon yarn speed, such that an increase in yarn speed produces an increase in pressure and a decrease in yarn speed produces a decrease in pressure such that the amount of size applied is substantially constant. The control mechanism includes a motor arranged to be energised when sizing conditions vary, e.g. by an indication from suitably positioned hygrometers. The control is such that the position of an immersion roller in a size trough is automatically adjusted synchronously with an adjustment of the position of the upper squeeze roller. The motor oscillates a shaft 22 and thus a link 24, which via a rod 36, rocker arm 37 and link 38 moves the roller 13 to increase or decrease pressure. The link 24 also moves a rocker plate 27 via a lug 25 engaging an arcuate slot 26 in the plate 27; movement of the rocker plate 27 operates through a link 29 and rod 30 to raise or lower the immersion roller 10. The rod (30) is provided with a rack (50) associated with an epicyclic gear (43), Fig. 2 (not shown), such that upon movement of the rollers (10), (13), the planet carrier (47) is rotated causing a change in speed of the driven feed roller (11), the tension in the yarn thus remaining substantially constant. Mechanism is provided enabling the roller 13 and an upper feed roller 11 to be moved clear to facilitate threading of the yarn.

Abstract: 951,987. Printing formes and processes. AFGA A.G. Nov. 15, 1961 [Nov. 16, 1960; June 29, 1961], No. 40865/61. Heading B6C. A process for making reproductions comprises heating a printing forme comprising a support coated with a relief layer containing a dyestuff having a melting or sublimation point of between 80‹ and 220‹ C. and incorporated in a binding agent (which will not soften at temperatures capable of melting or subliming the dyestuff) to temperatures above such melting &c. point, but below the softening point of the binding agent, whilst in contact with a copy sheet, whereby the dyestuff is partially transferred to the sheet, whereas the binding agent entirely remains on the support. Plasticizers and inorganic fillers may be incorporated in the coating. Suitable dyestuffs are dye bases of the triphenyhnethane series, e.g. Astra Blue base, Malachite Green, dispersion dyes e.g. Cellitone Blue G, Resoline Yellow RL, Smoke dyes, e.g. Sudan Red, Sudan Brown, Benzine soluble dyes, e.g. Benzine Blue, and oxidation dyes (fur dyes). Film-forming polymers such as carboxymethyl cellulose, an alginate, a pectin or a copolymer of maleic and acrylic acids may be used as binding agents. Several examples are described in the Specification. In one, a waterresistant paper support is covered with a mixture of 100 c.c. of carboxymethyl cellulose, 15 grams of Benzine Blue and 200 c.c. of glycerol and dried. The forme is made from this support by writing on a sheet of paper in contact with the coated surface. The coating is transferred to the rear surface of the sheet by the pressure of writing and this surface is suitable for use as a forme. The forme is then heated in contact with a sheet of paper at 150‹ to 160‹ C. for about one second, using a heated roller. About 100 copies may be made from this forme. In a further process the relief layer contains, in place of the dyestuff, an uncoloured transferable substance having a melting or sublimation point of between 80‹ and 220‹ C., capable, on subsequent treatment, of forming a visible reproduction on the copy sheet.

Abstract: The invention comprises 4-hydroxyalkyl-oxetan-2-ones of the general formula <FORM:1029047/C2/1> wherein R1 and R2 represent hydrogen atoms or alkyl groups or R1 and R2 together represent an unsubstituted or an alkyl or hydroxyalkyl-group substituted alkylene bridge having 1 to 5 methylene groups, and R3 and R4 represent hydrogen atoms or alkyl groups.  They may be prepared by epoxidizing a beta, gamma-unsaturated carboxylic acid of the general formula <FORM:1029047/C2/2> and reacting the resultant beta, gamma-epoxy carboxylic acid in an acid medium at pH 1.0 to 6.5 and at a temperature below 50 DEG  C. When peracetic acid is employed in the epoxidation step the reaction will proceed without isolation of the epoxy acid due to acetic acid formed during the epoxidation; any unreacted peracetic acid being decomposed, if desired, by the addition of a suitable catalyst, e.g. Pd or Pt. When the carboxylic acid reactant or epoxy acid intermediate have substituents bearing hydroxy groups, said reactant or intermediate may be in the form of a lactone due to interaction between said hydroxyl group and the carboxylic acid group.  4 - Hydroxy - 5 - ethyl - dihydrofuran - 2 - one is obtained as a by-product of the process of the invention employing hex-3-enoic acid as starting material.  3,3 - Dimethyl - 4 - hydroxy - dihydrofuran - 2 - one is obtained as a by-product of the process of the invention employing 2,2-dimethyl but-3-enoic acid-1 as starting material.
