Title: Method for minimizing deterioration of perishable products
Inventor: DIXON DAVID ARTHUR
IPC: A23L3/3418
Filed: 1966-01-14
Abstract: 1,132,151. Preserving food, flowers and live shell fish. BEST FERTILIZERS CO. 14 Jan., 1966, No. 1814/66. Headings A1A and A2D. Plant and animal matter subject to degradation in the presence of oxygen is preserved by loading it into containers and purging the atmosphere in the containers with nitrogen or a nitrogen-argon mixture, to reduce the oxygen content therein to a predetermined level between “% and 5% by volume, during a period of time such that substantially negiligible degradation of the matter occurs, and subsequently maintaining the oxygen content at substantially the predetermined level by further periodic additions of the purge gas. The purge gas is preferably supplied from outlet means communicating with the lower portion of a gas storage cylinder and hence introduced into the storage Container as a liquid spray, the vapourizalion of which serves also to reduce the temperature within the container. The gas cylinder may be housed either inside or outside the storage container. The contamer may be mounted on a vehicle or semi-trailer. The supply of purge gas may be controlled automatically in response to an oxygen sensing means or following the initial purge, may be supplied at a constant rate sufficient to compensate for leakage from the container The temperature humidity and carbon dioxide content of the storage atmosphere may also be controhed The plant and animal matter may be stored unpackaged or in small gas-pervious packages within the container or in non-gas-pervious packages in which latter case the purge gas is supplied to each package from a manifold. In the examples the materials preserved are: fruit and vegetables - lettuce, green beans, peas, sweet corn, asparagus, cauliflower, cantaloupe, strawberries, plums and tomatoes; cut flowers - carnations, roses, stocks and chrysanthemums; meatbeef, lamb, poultry and pork; fresh fish; and live shell fish - lobsters; oysters, crabs and clams. In one example lettuce is stored in an atmosphere the oxygen content of which is alternated between 0.25% and 10% by means of a continuous flow  of nitrogen and an interrupted flow of air.

Title: Improvements relating to the setting and flues of fire-back boilers
IPC: F24B1/183
Filed: 1935-01-19
Abstract: 445,735. Setting fireplace boilers. ROBINSON, T., 127, Ramsden Road, Wardle, Rochdale. Jan. 19, 1935, No. 1817. [Class 64 (i)] [See also Groups XI and X] In setting a boiler at the rear of a fireplace the back wall a<2> is left wholly uncovered and open to the action of the gases, the side walls of the flue immediately above it being constituted by bricks or blocks d which project from the side walls of the boiler cavity at the level of the boiler top ; the front and rear walls of this part of the flue are formed by tiles e joining the bricks d at the front and back ends. Preferably, as shown, the inner ends of the bricks d are inclined to reduce the flue width from approximately that of the boiler to that of the flue above, and are formed with recesses d<2> to receive the ends of the tiles e. The front tile is preferably removable for access to the flue. The boiler shown is provided with supporting flanges b at the ends which are built into the brickwork, this method of support allowing the whole of the underface of the boiler to be exposed to the gases.

At the end of the cylinder stroke the piston 14 uncovers a byepass 30 and the fluid passes through a conduit 31 and pipe 32 to operate the booster throttle (not shown) in the usual manner. For the reverse drive, pressure fluid is admitted by a pipe 33 and conduit 34 to the cylinder space 16, the cylinder is lowered. and the gears 7, 3 are meshed. Pressure fluid is admitted as required to the pipes 28. 33 by pilot valves operated by the latch on the reversing lever.

Title: Method of and Means for Automatically Opening and Blending in Definite Proportion Different Densities of Cotton, Cotton Waste, Wool, Wool Waste, Coloured Fibres and the like.
IPC: D01G9/00
Filed: 1918-01-02
Abstract: 120,676. Platt, Bros., & Co., and Wilkinson, H. Feb. 2, 1918. Feeding openers &c. - In an arrangement for blending fibres of different densities in definite proportions in which the fibres are fed into shoots and delivered therefrom to the actual mixing-apparatus, the feed into the shoots and the delivery therefrom is controlled automatically by weighted swing sheets which control through cords &c. the belt-forks of the hopper bale breakers &c. supplying the fibres. A swing sheet c in the shoot controls the driving of the hopper bale breaker supplying the fibre and prevents overloading. A swing sheet m in the shoot controls a belt-fork on the hopper feeder in which the mixing takes place and stops the drive to the delivery rollers h at the foot of the shoots when either shoot is running light. A swing sheet h<1> in the hopper feeder controls the stopping and the starting of the delivery rollers h in accordance with the accumulation of fibre in the hopper feeder.

Title: Improvements in or relating to locking devices for tool-holding or like set-screws
IPC: F16B39/32
Filed: 1943-02-09
Abstract: 563,437. Locking set-screws. AUSTIN, HOY, & CO., Ltd., and PROCTOR, S. E. Feb. 9, 1943, Nos. 2164 and 9970. [Class 89 (i)] Set-screws for holding tools, such as those in the boxes of coal-cutter chains, are locked by replacing a part of the thread by a turn or part turn of wire anchored to the screw at one or both ends. When anchored only at the leading end when screwing in the internal end 17 of the wire 16 is entered into a hole drilled at an angle of about forty-five degrees to the radius. Screws so fitted require a spanner to effect removal and are apt to damage the thread if removed frequently. To obviate this the spring 26, Fig. 4, may be anchored at each end in radial holes 24, 25 that are a clearance fit for the wire so that in whatever direction the screw is . turned the spring is always pulled from its leading end. In modifications, the spring may be such that one end is pushed as the other is pulled or a shorter spring may be permanently in position without play for pulling at either end or, as in Fig. 7, a longer spring for pushing at either end 57 or 58. If the spring be made to lie in one plane when free an additional locking is obtained when the ends are located in holes situated on the thread helix.

As described the path comprises a channel on a frequency division transmission system. In operation once a connection path has been established by closing selected contacts such as those shown in the concentrators CE 1 and CE2 but prior to ringing the called subscriber, the called end logic RL2 energises generator Gb. The tone produced is transmitted to the calling end of the path where it should be detected by receiver Ra but not by receiver Ra<SP>1</SP> which is arranged to respond only if the path is unbalanced. If Ra operates without Ra<SP>1</SP> calling end logic RL 1 responds energizing generator Ga causing a second tone to be transmitted to the called end. If receiver Rb but not Rb' responds then the path is considered efficient and the called subscriber rung.

Filed: 1954-01-27
Abstract: 746,107. Magnets; motor driving arrangements. SPODIG, H. Jan. 27, 1954 [Jan. 30, 1953], No. 2548/54. Addition to 684,052. Class 35. [Also in Group XXIV] In a permanent magnet assembly of the type claimed in the parent Specification, the intermediate soft iron disposed between identical poles of the magnets is formed as an axle, and the outer plates adjacent the remaining poles of the magnet have inwardly facing peripheral extensions. Fig. 2 shows two permanent magnets 2 with an intermediate iron axle 1 and two polepieces 6, 7. The outer ends of the magnets 2 are secured to iron cups 3, 4 having stub shafts 10, 11 respectively. Non-magnetic material may be used to fill up the free space around the magnets 2. Whereas the original construction of the device was intended to be employed as a magnetic filtration system, the present arrangement with the central axle 1 and stub shafts 10, 11 enables the device to be used also to drive or be driven by another relatively moving magnetic member. For instance, Fig. 4 shows a magnetic disc 12 on a spindle 13 arranged to make positive frictional engagement with the axle 1, thus obtaining a frictional and magnetic drive without slipping. The device may also be used as a roller to move iron rods &c. or as a driving or driven element in electric or other measuring instruments in which a rotating or rolling process takes place. The axle 1 may be recessed so as to obtain a larger bearing-surface with the corresponding engaging part of the other member. The attractive force of the axle 1 may be varied by covering it with a layer of non-magnetic material having different thickness.
