Title: Apparatus for coating elongate elements
IPC: B29C48/34
Filed: 1975-02-10
Abstract: 1483013 Paint or lacquer coating die HASBRO INDUSTRIES Inc 10 Feb 1975 [17 April 1974] 5479/75 Heading B5A A coating of paint, or laquer, material is applied around an elongate core L by a die head provided with a die D, having an opening 31 through which the core L passes and which is adjustably radially compressible, or expandable, to vary the thickness of the coating, the die head being also provided upstream of the die with a valve member G which is actuable to obturate the flow of coating material being delivered to the die D. When the core issues from an extruder upstream of the die, obturation enables the correct shape and size of the core to be obtained prior to commencing coating. The core passes through the die head to the die D, via a bore 58 in the member G and an aperture 24 in the die body, the member G being threadedly engaged in the die head, at 64, 66, for axial displacement to obturate the flow of coating material, upon abutment of a bevelled downstream face 56 of the member G, with a bevelled face 54 of a cylindrical sleeve 52 which extends upstream of the aperture 24 and is surrounded by an annular chamber 28 to which the coating material is delivered from a lateral die inlet 30. The member G is provided with a seal 62 to the die body, and is rotated by engagement of a tool in recesses 70. The die D comprises an elastomeric material, e.g. rubber, neoprene, or a butadiene polymer, and has a frusto-conical upstream surface matingly abutting a surface 34 extending downstream of the aperture 24, whereby the die D is radially compressible or expansible upon axial displacement of a member E, which is threadedly engaged at 26, 36, in the die body for the displacement, upon rotation by engagement of a tool in recesses 44. The opening 31 of the die D may be round or hexagaonal. The die head may be releasably clamped at a location, Fig. 1 (not shown), to apply a coating to a wire, or to a writing element extruded from an extruder upstream of the die, or either comprising a casing extruded around a writing core which may be preformed or comprise simultaneously extruded pigmented or graphite lead, or a casing having a bore and for use as barrels of mechanical pencils or ball point pens.

Title: Improvements in or relating to the processing of fruit and vegetables
IPC: A23L3/00
Filed: 1945-03-06
Abstract: In the cooking, scalding or other similar processing of vegetables or fruit with hot or boiling water, there is used, to reduce darkening in colour, water to which has been added a soluble compound which will prevent formation of a coloured compound between iron or other metal, e.g., copper, lead, tin or silver, and organic constituents, such as certain tannins, already present in the vegetables or fruit. The added compound may be such as to form an insoluble compound with the metal and so precipitate it, e.g. a soluble phosphate forms an insoluble compound with iron in the water, to form with the metal a soluble compound which is colourless or nearly so and gives rise to a very low concentration of ions of the metal, e.g. p-hydroxybenzoic acid so combines with iron in the water, to form insoluble compounds with the organic constituents and so precipitate them, e.g. gluten or gelatine combines with tannins or other phenolic compounds of the vegetables or fruit, or to combine with the organic constituents preferentially to the metal to give colourless compounds, e.g. aluminium sulphate so combines with tannins or other phenolic compounds of the vegetables or fruit.  By the employment of an appropriate mixture of sodium dihydrogen phosphate and disodium hydrogen phosphate, e.g. in concentration equivalent to 0.2-0.4 per cent of sodium dihydrogen phosphate, there may be obtained also the pH value suitable for the particular vegetables or fruit undergoing the treatment.

Filed: 1932-02-24
Abstract: 377,601. Diathermic apparatus. KILLERICH, J. G. F., 4, Rygaards AllÚ, Hellerup, Denmark. Feb. 24, 1932, No. 5569. [Class 81 (ii).] A diathermic apparatus adapted to generate continuous high-frequency currents through the body, Fig. 1, is characterized by two valves 1, 2 connected in push-pull position and producing high-frequency oscillations in a circuit comprising a tunable condenser 3 and induction coil 5, which is coupled inductively with the aperiodic therapeutic circuit proper. Said circuit, comprising electrodes 12, 13 and parts of the patient's body, may be coupled to the oscillating circuit in various ways by means of the switch 7, 8, 9. In position 7, the coupling is through induction coil 6, this coupling being used in medical diathermic treatment. In positions 8, 9, the therapeutic circuit is coupled automatically through condensers 10, 11 directly to the oscillating circuit, the coil 5 being used as an auto-transformer. The position 8 is used when coagulations are to be effected ; the position 9 when surgical incisions are to be made, in which case the electrode 12 is formed as a needle or knife, so that a localized burning of the tissue is produced. A thermocouple 16 is mounted in the electrode-holder 15, Fig. 2, or in a plug box 26 fitting on to the electrodeholder, Fig. 3, and is connected to galvanometer 17 for measuring the current. In the construction shown in Fig. 2, a switch 23 is provided, but in Fig. 3, wherein the electrode 12 is constructed for heating purposes, such is unnecessary. The plate voltage, and hence the operating current, is varied by means of potentiometer 18 preferably mounted in a separate box and pedal controlled. A neon lamp 20 fitted with two electrodes of unequal size is disposed across the leads from the mains, whereby when correct connection is made, say a luminous red letter is seen ; otherwise, only a line is visible. Reference is made to the use of the apparatus in dentistry.

Title: Improvements in or relating to the production of polyamides
IPC: C08L77/00
Filed: 1942-05-14
Abstract: Polyamides having enhanced water absorption properties and increased elasticity, are prepared by heating in the molten state, at amide-forming temperatures, a mixture of at least two pre-formed synthetic linear polyamides, at least one being soluble in water, and at least one being insoluble in water, heating being continued until a homogeneous blend is obtained. The blend usually contains 5-80 per cent by weight of the water-soluble component, and temperatures of 180 DEG  C.-320 DEG  C. are used.  Heating is preferably continued until a product is obtained from which, on solidification, not more than 10 per cent of the soluble component can be selectively extracted by prolonged solvent treatment.  Many starting polyamides are specified, and examples are given of the preparation of melt blends from: (1) polyhexamethylene adipamide and polytriglycol adipamide; (2) polyhexamethylene adipamide and N-methyl polytriglycol adipamide; and (3) N-methyl polytriglycol adipamide and an interpolymer of hexamethylenediammonium adipate hexamethylenediammonium sebacate and epsilon-caprolactam.  The products may be cold rolled or cold drawn, and treated with swelling agents such as water or short chain aliphatic alcohols, and may be used in the production of films, filaments, yarns and fabrics.  Such fabrics, by exposure to steam, acquire considerable elasticity and anticrease properties. Specifications 474,999, 501,527 and 535,138 are referred to.

Title: Improvements in or relating to methods of making poppet valves, particularly hollow poppet valves, and the improved valves resulting therefrom
IPC: F01L3/02
Filed: 1945-03-08
Abstract: 594,562. Making valves. THOMPSON PRODUCTS, Inc. March 8, 1945, No. 5787. Convention date, Aug. 25. 1944. [Classes 83 (ii) and 83 (iv)] Extruding ; forging.-In a method of manufacture of poppet valves, a length of tubing is extruded. around a mandrel to form a hollow stem portion and the operation stopped whilst a portion of the tube is still greater than the valve stem size ; this portion being forged to form the head of the valve. The tube 10, Fig. 3, is heated to forging temperature and placed in an extrusion die 11 having a tapered receiving cavity 11a converging towards a throat 11b and a cylindrical bore 11c. A ram 12 having a mandrel formed integral is lowered on to the end of the tube, forcing it into the die block until a hollow stem portion 15a, Fig. 6, is formed beyond the die outlet 11c. The operation is stopped when a sufficient length of the stem portion is extruded and whilst a' portion of the tube greater in diameter than the stem-remains, and the blank is transferred to a further die 13, Fig. 6, for forming the head. This remaining unextruded portion of the tube is acted on by a ram 14, having a mandrel 14a of the same diameter as the internal bore of the valve stem, to form a solid head portion with an outwardly flaring neck 15c and flat top 15f. The rounded tip 15b of the valve stem is then cut off and a tip of wear-resisting material 16, Fig. 9, welded on to close the pipe 10f formed in extruding. The valve stem is then filled with coolant such as sodium and a plug 17, Fig. 9, welded into the head, preferably electrically, which causes localized heating only to avoid raising the temperature of the coolant. In a modification, the valve head is formed hollow and is closed by flat disc, which is preferably secured by projection welding. In a further modification, a plug of wear-resisting material is welded into the end of the tube before extrusion, so that after extrusion the pipe 10f, Fig. 6, will be closed by this plug. The head may be formed solid or hollow as before described. The valve stem tip is ground flat and the valve finished by filling with coolant and closing the head as described above.

Title: Improvements in or relating to biers for hearses
IPC: A61G21/00
Filed: 1938-02-24
Abstract: 512,032. Hearses. DOTTRIDGE BROS., Ltd., and BROWN, P. Feb. 24, 1938, No. 5919. [Class 108 (i)] A bier structure for a funeral hearse comprises a supporting stand 1 carrying a bier frame 4, the whole or a part of which is slidable relatively to the stand in order to facilitate the insertion or removal of a coffin into or from the hearse, particularly in the case of a motor hearse in which the rear panel of the body flares outwardly at the bottom below the door and prevents close approach of the coffin bearers. As shown, the bier frame, which is of conventional outline and provided with the usual rollers and transverse members 6, Fig. 3, carries angle irons 9 and channel irons 10, further channel members 12 within the irons 10 each serving as an outer race for ball-bearings 13 guided in a cage 14 which runs between the members 12 and runners 15 secured to irons 17 on the stand 1. Thus, as the frame slides on the stand, the ballcages 14 move between the runners and channel members. Rollers on one end of the stand take the weight of the frame at that end to prevent bending of the mechanism under heavy loads, and stops and co-operating buffers on the stand or frame limit the movements of the frame. To lock the frame in any position on the stand, a spring-pressed bolt 26 on the frame is adapted to engage one of a number of holes in the stand, and is adapted to be withdrawn from the hole by means of a cross-pin 32 on the bolt engaging a fork 31 pivotally mounted on a bracket 33 and operated by a rod or tube 34 which extends to the head of the frame and is rotatable by a handle. The ball-bearing runner mechanism may be enclosed in a casing and the supporting stand may incorporate rise-and-fall mechanism. The channel members 10, 12 may be replaced by a single channel member and the runner members may be on the bier frame and the channel irons on the stand. Similarly the locking mechanism may be on the stand and arranged to engage apertures on the frame. In another construction, Fig. 4, a part only of the bier frame, consisting of a framework 43, is slidable relatively to a fixed frame 40, 41, 42 and is guided therein by leaf springs 45 and/or rubbing blocks 46. The locking means comprises a clamping device 49, 50 associated with a slotted bar 48 on the framework 43 and with a hole in a cross-bar 47 secured to the fixed frame. It is stated that the bier frame may-be mounted for transverse sliding movement to facilitate side loading or unloading.

Title: Improvements in or relating to the mercerising and lustreing of textile fibres
IPC: D06B7/00
Filed: 1939-02-23
Abstract: 529,636. Winding yams and rovings. BRANDWOOD, J. Feb. 23, 1939, No. 5999. [Class 120 (ii)] I[Also in Group IV] Rovings or fully twisted or spun or doubled yarns are wound upon perforated holders with winding tension sufficient to draw the component fibres as far as possible to their full or natural length, the fibres of the roving or yarn of one layer being nipped and held fast in that position or condition by succeeding winding layers, and mercerising and other liquids are then passed through the wound masses of roving or yarn by differential pressure. The materials are thus mercerised and rendered lustrous. For winding a roving on to a perforated holder, the roving may be passed over a tensioning device from a holder upon which it has already been wound, and the supply holder and the perforated holder are rotated at equal peripheral speeds. As shown in Fig. 1, a roving is taken from a bobbin 17, over a spring tension device 20, 21, and is wound upon a perforated bobbin 8. Bobbin 8 is frictionally driven by drum 10 which is geared to drum 16. The drum 16 drives bobbin 17 by friction. The traverse mechanism comprises a pulley 22 mounted on one end of arm 23, the other end of which is attached to the traverse rod 7. This rod is provided with arm 25 which bears an anti-friction bowl 26 engaging in the helical slot 6 in the traverse cam 5. This cam is geared to drum 10 at a reduced ratio so as to cross-wind the roving on drum 8. A roller weight 29 within drum 8 presses the latter upon its driving drum. The material wound on the perforated bobbins is placed in a liquid-treatment apparatus and mercerising and washing liquids are passed through the windings by differential pressure. Air may be passed through the windings to remove surplus liquid, and the materials may then be dried by passing hot air through the windings. The device shown in Fig. 1 may be used for re-winding the treated rovings. When winding yarn or roving on to the perforated bobbins the supply bobbins, cops, or other units may be moistened. Already twisted yarns may be wound on to the perforated holders by taking them off a pirn or other package, leading them through tensioning eyes 31, Fig. 3, and thence to a perforated drum 8 mounted on winding mandrel 33. Specification 482,817 is referred to.
