Title: Method and apparatus for dyeing tubular knit material
IPC: D06B3/10
Filed: 1961-09-07
Abstract: 977,400. Treating textiles. SAMEOE HOLDING CORPORATION. Sept. 7, 1961 [Sept. 13, 1960], No. 32169/61. Headings D1L and D1S. Apparatus for continuously dyeing tubular knit material, comprises means for spreading the material to a flat form and to a predetermined uniform width, a dye bath roller means providing nips for compressing the spread material and releasing it in the dye bath and roller means for extracting excess dye from the material emerging from the bath, said roller means being arranged to maintain continuous contact with the material during said compressing, releasing and extracting steps. In the arrangement shown a spreader 10 is positioned to receive tubular material from a prior processing station, and sets it to predetermined width. The spreader 10 also advances the material towards a dyeing station 11. Steamers 12 and/or squeeze rolls 13 may be provided depending on whether the material is dry or wet to pre-condition the material prior to entry to the dye bath. After passing through the dye bath, in which the material passes through the nips of a number of pairs of squeeze rollers, the material passes between the nip 42 of a pair of pressure rollers covered with resilient material to extract excess dye from the fabric. The reservoir 19 (Fig. 3) of the dyeing apparatus has rotatably mounted therein and below the level of the liquid, rollers 25 and 26 and a roller 27 of larger diameter and only partly immersed. Roller 27 forms nip 42 with a pressure roller 43 and is connected to suitable drive means. Mounted below rollers 25-27 and positioned in the spaces therebetween are rollers 29, 30. These are suspended by arms 31, 32 from yoke 33 which in turn is connected at pivot 36 to a lever 35 pivoted at 37 to the frame of the reservoir. Lever 35 carries at the other end a handle 38 which can co-operate with a plurality of notches in a bracket 39. By selecting the position of handle 38 on the rollers 29, 30 can be moved away from the other rollers to permit threading of the material through the rollers or can be moved into contact therewith to form nips for the material to pass through the loading between the rollers being. produced by the resilience of the lever system. The passing of the material through the nips of the rollers results in a sponge-like action-air and liquid is squeezed out of the material at each nip particularly the first one, and liquid is drawn back into the material between the nips in a uniform manner. In a further embodiment, in order to ensure uniformity of dyeing, the material may first be passed through a similar device to that described above but containing water so as to ensure a uniformity of water content and of temperature before the dyeing operation. The spreader 10 consists of a pair of belts 14, 15 supported within the fabric tube on a frame 16 which may be adjusted to a predetermined width to stretch the fabric widthwise. The fabric is propelled forward over the spreader by means of the belts 14, 15 driven by edge rolls 17, 18.

Title: Golf practice apparatus
IPC: A63B69/00
Filed: 1958-10-13
Abstract: 855,529. Photo-electric indicating systems. VICTOR DEVELOPMENT CO. Oct. 13, 1958 [Oct. 31, 1957], No. 32567/58. Class 40(3). [Also in Group XV] In golf-practice apparatus in which a player strikes a captive ball 4 and the probable line of flight of a free ball if similarly struck is indicated on a board 10 by the selective illumination of lines of lamps, the selection is effected by the passage of the club head over two lines 18, 20 of photo-electric tubes 16 disposed transversely of the direction of swing of the club head, the head occluding one tube of each row. The apparatus may be coin freed by unit 9 which controls the current to lamp 13, the light source of the photo-electric system. The tubes 16 are mounted beneath a translucent plate 12, each is surmounted by a frusto-conical part 17, and each supplies, when occluded by the club-head, a positive pulse through capacitor C-3l3 to the grid of one of thyratrons V301-V314 which is rendered conducting. The tubes of line 18 are connected to valves V301-V306 and those of line 20 to valves V307-V314. Firing of one of the latter increases the negative bias on the valves so that occlusion of further tubes by the completion of the swing does not cause firing of the associated valve and energises the operating coil 159 of a multi-bank stepping switch 150. The anodes of valves V301-V306 and valves V307-V314 are connected to the contacts of banks 151 and 158 respectively of the switch in such manner that, for each switch position, a different pair of valves are in circuit with the switch wipers. These wipers are each in circuit with one coil of a relay having two coils both of which must be energized to actuate it. The relay, when actuated, breaks the circuit to coil 159 operating switch 150. Thus the switch will step round until it arrives at the contact position corresponding to the pair of photoelectric cells occluded by the club-head and will then stop. Further banks of contacts of switch 150 are connected to the appropriate line of lamps on board 10 and the appropriate line is lit depending on the position of switch 150.

Characters printed in magnetic ink on a tape 10 are sensed in a series of parallel scans by magnetic reading heads 17, 18, 19 and 20 spaced around the periphery of a rotary disc 12, the tape moving across the line of movement of the heads in timed relationship to produce a train of pulses characteristic of the character sensed. The four heads are connected in series and the signals generated are taken off via a slip-ring. The tape 10 is fed by a pair of capstan rollers geared to the shaft 13 through a variable gear-box 13a and is curved by surface 15 of guide 16 to match the surface of the disc 12.

Abstract: Surgical dressing material comprises comminuted egg-shell membrane the total surface area of which is greater than that of the weight of egg-shell membrane.  Egg-shell membranes are separated from cooked or uncooked egg-shells mechanically or chemically and are disintegrated in a homogenizer or blender in air or a non-softening liquid to form non-fibrous particles or in a softening liquid or gas to form fibres having a diameter of the order of 4-7 microns.  Softening liquids used are water-free methyl ethyl ketone, 1 : 4-dioxane, benthiazol, pyridine, pentane-diane or chloroform.  Softening agents are water, steam, aqueous solutions, methyl alcohol, glacial acetic acid, mercapto-acetic acid, molten phenol crystals, formamide, propionic acid, beta-mercapto-propionic acid, lactic acid, anhydrous pyridine, chlorophenols or cresols.  The membrane fibres or particles are separated from the suspending liquid by filtration, centrifuging, evaporation &c. which is repeated after washing. Any aggregates of fibres or particles so formed are separated in a homogenizer, there being no suspending liquid.  The resulting powder or fibrous mass is applied to the wound directly or to a paper, fabric or synthetic plastic backing to which it is made to adhere by compositions including pectin, gelatin, starch or starch derivatives, vegetable gums or synthetic resinous polyamine substances.  Fibrous membrane particles may be felted together with a proportion of natural or synthetic fibres or during the felting operation a layer of natural or synthetic fibres may be deposited on a layer of egg-shell membrane fibres.  The fibres or powder may be partially digested with ensymes, e.g. papain, ficin, pepsin, trypsin, bromelin &c. or reduced or oxidized by hydrogen peroxide, urea peroxide, peracetic acid, performic acid mercapto-acetic acid, mercapto-propionic acid or substances with a thiol group and their soluble salts.  The fibre or powder may be sterilized or combined with drugs, antibiotics or bacteriostatic agents, e.g. neomycin, bacitracin, tetracyclines, chloramphericol or "sulfa" drugs.
