Title: Improvements in or relating to automatic bobbin changing mechanisms in looms
IPC: D03D45/20
Filed: 1961-02-24
Abstract: 977,012. Automatic bobbin changing in looms. VALENTIN PATENT-GESELLSCHAFT G.m.b.H., and TEXTILMASCHINENFABRIKSCHWENNINGEN G.m.b.H. Feb. 24, 1961 [Feb. 26, 1960], No. 6789/61. Heading D1E. When bobbin changing is initiated, a hammer 35 is operated in the usual way by a striker on the slay encountering a dog 50; a bobbin 65 held in a clamp 38 is thereby inserted into the shuttle. A ratchet mechanisms 14, actuated by linkage 195 from an eccentric 197, then rotates a skew gear 22 meshing with two racks 25, 88. The rack 88 moves forwards, turning an arm 94 carrying jaws 96, which enter the magazine and grip the head of a bobbin; the arm 94 is operated through an overrunning clutch 122 which allows it to stop if it encounters a bobbin before reaching the bottom of the magazine. Meanwhile, a cam 30 on the rack 25, which is moving to the left, produces a partial stroke of the hammer 35 to press the bobbin 70, lying loose in a trough 45, into the clamp 38. A dog 33 on the rack, acting through an arm 85 and a fork 82, moves a tip bunch extractor 80, described in Specification 977,013, on to the nose of the bobbin 70 which is now in the position 68; the inner end of the rod carrying the fork 82 blocks the path of the shuttle feeler 83 and thereby prevents initiation of another bobbin changing operation whilst the tip bunch is being removed. The direction of movement of the racks is now reversed by a striker 28 on the rack 25, which switches over the pawls of the ratchet mechanism 14 so that the skew gear 22 is rotated in the opposite direction. The rack 88 now moves rearwards to swing the jaws 96 out of the magazine and down through a slot 48 in the trough 45, thereby dislodging the bobbin from the jaws and allowing it to roll down the trough to the position 70.

Title: Improvements in or relating to light-sensitive photographic films
IPC: G03C1/52
Filed: 1940-04-15
Abstract: 536,714. Photographic diazotype films. BRITISH OZAPHANE, Ltd. (Soc. Anon Le Film Ozaphane.). April 15, 1940, No. 6805. [Class 98 (ii)] A photographic film comprises a cellulose acetate film without any chemical change therein impregnated from one or both sides to any desired thickness thereof with a light sensitive diazo compound. With cellulose acetate, either cellulose diacetate or triacetate, the film is swelled by incorporating a swelling agent in the sensitizing solution such as methyl, ethyl, or isopropyl alcohol. Volatile solvents such as formic acid, acetic acid, acetone, diacetone alcohol, ethyl lactate, and methyl glycol, and non-solvents such as water, benzene, and toluene, and plasticizers such as tricresyl phosphate, triphenyl phosphate, triacetin, and dichlorhydrin may be added. The swelling medium may be water and a swelling agent per se. The sensitizing solution may also contain an azo dyestuff component, and the diazo compound should be incapable of coupling in a neutral or acid environment. An acid, stabilizing agents, and metal salts such as copper chloride or sulphate, nickel chloride, zinc chloride, cadmium chloride, and sodium or potassium titanium citrate, tartrate or oxalate may be incorporated. Development may be effected with aqueous alkali or gaseous ammonia. Alternatively, development may be effected by treatment with an azo dyestuff component in an aqueous solution or in an aqueous alcohol solution, with or without an alkali. In an example, cellulose diacetate film may be impregnated with an aqueous solution containing sodium 1-diazo-2-naphthol- 4-sulphonate, phloroglucinol, thiourea, hydrochloric acid, and thiourea. In a second example, cellulose acetate film may be impregnated with phenyliminoquinone diazide sulphate, resorcinol and methyl alcohol. The films may be sensitized throughout or partially from one or both sides.

Title: Improvements relating to grain or seed drying machine
IPC: F26B17/00
Filed: 1947-03-12
Abstract: 627,422. Drying systems. FOSTER, F. H., NEWMAN, H. R., and BUTTERLEY CO., Ltd. March 12, 1947, No. 6868. [Class 34(ii)] A grain dryer comprises a casing having a number of superposed inter-communicating compartments in each of which is a series of louvred trays down which the grain cascades in succession whilst travelling back and forth across the dryer, drying air being passed through each series of trays and the casing being g provided with grain feed. and outlet branches and with air inlets and outlets. As shown, the casing comprises four compartments, in each of which is a series of trays b, each tray overlapping the succeeding tray and being pivoted at c in slides mounted in slots d. The slides are raised and lowered by rods e by means of cams, the trays being lowered successively from the delivery end of the series so that each one successively slopes to cause the grain to flow down to the delivery end and thence to the next succeeding compartment where the trays are arranged to cause the grain to flow in the opposite direction in the casing and so on for each succeeding compartment until it is delivered by the chute 9 out of the drier. In each series of trays after the trays have been successively lowered, they are raised simultaneously by the rods e and the process of lowering and raising the trays is repeated. Heated air is supplied to the two intermediate compartments through branches 2, 3 where it passes through the grain on the trays. Heated air from compartment 2 is led into the top compartment by branch 4 and this air, which is laden with moisture derived from the drying grain, deposits some of its moisture on the incoming grain to impede case hardening of such grain. The air from the top next succeeding and lowest compartment is discharged through a duct 5 and cool air is admitted to the compartment below the top one. Cold air is also admitted to the lowest compartment to reduce the temperature of the grain before delivery. Trap or baffle plates are arranged at the sides of the trays to divert air passing up the sides of the casing on to the grain on the trays.
