Title: The treatment of cellulosic textile materials to improve their dye affinity and otherproperties
IPC: D06P1/649
Filed: 1943-07-22
Abstract: The dye affinity, resiliency and handle of cellulose textile materials, e.g. natural or regenerated cellulose textile materials, is improved by treating them with an aqueous solution containing formaldehyde and a guanidine salt of an unsaturated carboxylic acid either as such or in the form of their water-soluble condensation product and heating the treated materials to convert the components or the water-soluble condensation product into a water-insoluble condensation product. Specified guanidine salts are the acrylate, methacrylate, styrylacrylate, alpha-chloroacrylate, maleate and cinnamate.  The treatment may be effected under acid, neutral or alkaline conditions and, if desired, in the presence of a catalyst, e.g. ammonium thiocyanate.  The treated materials may be dyed with acid wool, direct cotton and chrome dyestuffs.  In the examples, viscose staple fibre is treated in: (1) an aqueous alkaline solution containing guanidine methacrylate and formaldehyde, removed, dried, heated and dyed in a bath containing Eriochrome Azurol B, potassium chromate and ammonium sulphate; (2) an aqueous acidic solution containing guanidine alpha - chloroacrylate and formaldehyde, removed, dried, heated and dyed in a bath containing Eriochrome Black T and acetic acid with a subsequent addition of formic acid and sodium dichromate; (3) an aqueous alkaline solution containing guanidine styrylacrylate and formaldehyde, removed, dried, heated and dyed in a bath containing Solochrome Brown M.O.S. potassium chromate and ammonium sulphate; (4) an aqueous acidic solution containing guanidine cinnamate and formaldehyde, removed, dried, heated and dyed in a bath containing Coomassie Navy Blue 2RNS and acetic acid with a subsequent addition of potassium dichromate.  The examples also specify methods of preparing guanidine methacrylate, alpha-chloroacrylate and styrylacrylate by the careful addition of a concentrated aqueous solution of guanidine carbonate to an ethanol solution of the corresponding acid, i.e. methacrylic, a -chloroacrylic or styrylacrylic acid.  Styrylacrylic acid may be prepared by refluxing cinnamic aldehyde, malonic acid and pyridine. Specifications 433,143, 450,516, 493,938, 546,050, and 549,214 are referred to.

Filed: 1924-05-15
Abstract: 239,899. Bamford, J. May 15, 1924. No Patent granted (Sealing fee not paid). Indicating particular readings.-The tuning-in dials or like parts of wireless receiving apparatus &c., are provided with indicating tabs, adjustable on or about the dial, by which the tuning-position for receiving any particular station may be shown. In Fig. 1 the dial 11 moves past a fixed point 13 on the panel, and the tab 15 is adjustable along a rib 14, or a slot, in the dial. The tab 15 preferably engages frictionally with the rib or slot by means of a spring clip 18, and is marked at 16 with the call sign &c. of the station, as shown in Fig. 4. When the dial 11 is attached to the panel 13<a> and is traversed by a moving pointer 19, as shown in Fig. 6, a wedge-shaped slot 14 is formed in the dial, and the tab 28 is carried on a stud 26, the head of which engages the walls of the slot. Alternatively cork or like material may be let into the slot and the tabs secured thereto by short pins. Tuning ceils fitted with an adjustable slider working on a longitudinal bar are provided with a second parallel slotted bar in which the indicators are adjustably secured. One half of the complete swing of a variable condenser may be utilized for indicating the tuning for one range of wave lengths, and the other half for another range, different inductance coils being used for the two ranges. A series of ranges may be covered by the use of concentric slots or ribs on the dials or panels. Reference has been directed by the Comptroller to Specifications 1684/14 and 237,035.

Abstract: 418,678. Gramophone pick-ups. BRAUN, W. M., 17, Cretzschmarstrasse, Frankfort-on- Main, Germany. April 27, 1933, No. 12286. [Class 40 (iv).] A gramophone pick-up comprises a permanent magnet 11 secured to base 10 by a strap 12 and having U-shaped polepieces 15 between the lower arms of which an armature 21 is pivoted, the armature extending upwards through a coil 19 into the gap between the upper arms of the polepieces. According to the invention, the free end of the armature in the upper air gap is surrounded by a rubber &c. sleeve 26 normally contacting only with the armature to prevent the latter contacting with the polepieces. The coil bobbin may be held in position by grub screws 20 threaded into the polepieces and may house a rubber tube 25 surrounding the armature portion proper and having its upper part partly cut away by oblique cuts to form a wedge. The armature consists of a tube of cruciform shape, its upper extremity being flattened, but of increased width. The polepieces are preferably laminated and the length of the outermost laminations is successively decreased (Fig. 3, not shown) in order to provide maximum flux density in the air gap. The ends of the coil 19 are connected by leads 27 to lugs 28 secured to the base 10 by studs 29.

Title: Improvements in ship's propellers
IPC: C23F13/02
Filed: 1940-07-30
Abstract: 541,600. Screw propellers. CHANT, J., and HOAR, T. P. July 30, 1940, No. 12317. [Class 114] With the object of preventing corrosion of the blades of a ship's propeller due to galvanic action, the blades are mechanically linked to the propeller shaft by means of bodies of rubber or like electrically insulating material, which are so disposed that the torque is transmitted from the propeller shaft to the blades by subjecting the rubber &c. bodies to compressive forces only, i.e. without imposing upon them any tensile or shearing forces. As shown the propeller blade with hub P is mounted upon but electrically insulated from a metallic liner B which is keyed to the shaft S by a key K so as to rotate therewith. The insulation comprises a rubber sleeve I<SP>1</SP> and rubber annuli I<SP>2</SP>, I<SP>3</SP> spacing the hub P from the liner B, flange F thereon, and nut N<SP>1</SP> on the liner. For the transmission of the torque pins D extend from the flange F into recesses on the hub P lined with insulation I<SP>4</SP>, which is thereby subjected to compressive forces only. A lock-nut N<SP>1</SP> and safety pin L secure the whole. Alternatively, projecting pins may. be provided on the hub P to engage lined recesses in the flange F, or co-operating keys and recesses may be provided on the liner B and hub P. Or, in a further modification the blade of the propeller may be separated from the hub P by interposed rubber elements, but connected thereto by bolts passing through rubberlined holes. If desired, the electrically insulating elements may be constituted as fabrics impregnated with rubber or with thermosetting or self-setting resins and adapted to adhere to the surfaces to be electrically insulated.

In a deflection coil system the line deflection ciols are of the saddle type and are wound so that they have a greater concentration of turns towards the outer edges of the two longitudinal limbs of each coil than along the adjacent edges of the two limbs, and the frame deflection ciols are toroidally wound outside the line deflection coils and have a greater concentration of turns at the centre of each coil than at the remote edges. In one embodiment a coil supporting member of a synthetic material such as polythene comprises two semi-cylindrical parts 1, Fig. 1 having flanges 1a, 1b and two saddle type line deflection coils 2 are located in the bore of members 1 by projections 1c. 'Flange la is flared to fit over the conical part of the cathode ray tube of a television receiver of the wide angle deflection type. The frame deflection coils 3 which are preferably wave wound are wound about a toroidal yoke 4 of magnetic material which may be in several sections as shown in Fig. 2 and are located by projections 1d on the outside of members 1. The line deflection coils 2 have a greater concentration of turns at the outer edges 2a of their longitudinal limbs than along their adjacent edges 2b, and the frame deflection coils which comprise two windings 3 have a greater concentration of turns at the centre 3a than at the remote edges 3b.
