Title: Process for the treatment of edible or ingestible substances and the products thereof
IPC: A23L1/0522
Filed: 1954-03-10
Abstract: A granular or powdered ingestible substance, exemplified by dried milk, sugar, cocoa, or a granular or powdered pharmaceutical preparation, drug, analgesic, vitamin or hormone, and another ingestible substance which is compatible with the first, is soluble or swellable in aqueous liquids and is coating or binding agent are compounded without undue rise in temperature, to form grains in which cores of the first substance are embedded in the second substance. The coating substance, exemplified by sugar, a mixture of sugars, or starch, an edible vegetable gel, pectin, or gelatine with sufficient sugar to render it non-hygroscopic, may be added as a highly concentrated liquid, and may penetrate the cores as well as coating them.  The core substance may be a mixture.  Treatment of swellable or soluble core substances may comprise spraying of the core substance with the coating substance in liquid form, granulating and drying the sprayed product, spraying the dried granules with the coating substance in more concentrated liquid form, and again granulating and drying. Examples are concerned with (i) making a cocoa preparation which is readily dispersible in hot milk by spraying cocoa powder in a rotating drum with a hot, supersaturated solution of sugar while maintaining the cocoa at 33 DEG C., granulating the mixture, and drying the granules at not above 33 DEG C., (ii) making a milk preparation which may be stirred into warm or hot water to form a stable dispersion by spraying dried milk powder in a rotating drum with hot 75 per cent sugar solution while maintaining the powder at not above 50 DEG C., partially drying the product at 30-45 DEG C., pressing it through a sieve to produce 1 mm. granules, completing the drying, spraying these grains with 75 per cent sugar solution, drying, and sieving to separate dust from the coated grains, and (iii) making a blancmange preparation for stirring into hot milk or water by moistening a mixture of maize starch, swollen rice starch, sugar, and vanilla or fruit flavouring, and, if desired, dried whole or skimmed milk, in a rotating drum with a hot 80 per cent sugar solution, pressing the mass through a sieve to produce 1 mm. grains and drying completely at 30-40 DEG C.

Title: Improvements in or relating to tapering box-and-pin-type threaded couplings
IPC: F16B39/30
Filed: 1955-03-14
Abstract: 786,652. Pipe couplings. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. March 14, 1955 [March 16, 1954], No. 7378/55. Class 99(1). [Also in Group XXIV] In a tapering pin-and-box type threaded coupling the two members, the pin and the box are provided with tapering threaded surfaces, such that when the pin has been screwed tight into the box the outer flanks (as defined) of the pin threads and the inner flanks (as defined) of the box threads are loaded more heavily than the other flanks. A small number of the outer flanks of the pin threads and the inner flanks of the box threads at or near the middle of the screwed threads may remain unloaded. The couplings may be used at many points in welldrilling apparatus such as tool joints casing collars, subs, drill collar joints and drill bit joints. In Fig. 4, the pitch of the thread of the pin 1 is bigger and that of the box 3 smaller at the middle part of the thread. Thus the outer flanks of the pin thread press against the inner flanks of the box thread. The threaded part of the pin is under compression. The pitch variation may be provided in only one of the screw threads. In Fig. 5 the pitch P2 at the right hand side of the thread is smaller than P1. The thread may be interrupted at a point where the pitch is varied. In Fig. 6 the pitch P2 is greater than P1. The difference between the pitch diameters of the pin and box threads near the mid point of their length is smaller than at either end. In a modification of Fig. 6 the box pitch diameter line is straight. The pin of the screw thread is divided into two parts having tapers which differ from each other and also from the taper of the box thread 4. The transition between the two tapering parts of the pin is designed to take place more or loss gradually. In another modification, the taper of the pin may be constant and the box may have two parts with different tapers such that the taper of the part near the open end of the box is larger and the taper of the part near the inside of the box is smaller than the taper of the pin. In addition the pitch of the pin screw thread may be made different on two parts of the pin, it may, for example, be made equal to the pitch of the box thread over the left hand part of the thread. Couplings of the kind shown in Fig. 6 and in Fig. 7 (not shown) in which there is a small difference in pitch between the pin and box threads may in addition be provided with local pitch variations such as those provided on the threads of the couplings shown in Figs. 4 and 5. Sealing, instead of being by means of shoulders 5, 6, may be provided by engaging tapering faces. The box may be preheated and cooled after the pin has been screwed into it. The threads of both the pin and box may comprise two parts with different tapers or a cylindrical part and a tapering part. Dimensions of a coupling according to the invention are quoted and results of a test thereon. A coupling with threads 1 in. longer than the standard length was also tested.

Filed: 1926-03-18
Abstract: 272,985. Shell-Mex, Ltd., and Lawson, J. March 18, 1926. Regulating delivery by admission of air. -In a liquid - measuring device, particularly a kerb - side petrol pump, of the kind comprising two measuring- vessels filled alternately by a pump, and with valve-change-over mechanism actuated by the rise in the pressure of the liquid, air is admitted to the suction side of the pump when the desired quantity of liquid has been measured or when the pump is actuated too rapidly. As shown in Fig. 1, the lever 1, which is rocked as described in Specification 272,296, [Class 69 (i), Hydraulic apparatus &c.], lifts a valve 13 from its seating 14, making a connection between a port 11, leading from the main supply reservoir and the pump suction pipe 16. The vacuum in the pump suction is thus destroyed. If the pump is actuated too rapidly, the increased vacuum thus obtained causes the spring-valve 8 to rise from its seat, and the vacuum is similarly destroyed through the port 9. In a modification, the ball valve 8 is omitted, and the lever 12 is actuated by a cam-and-roller device and by a lifting-spring.

Patent GB-605706-A (GB)
Title: Improvements in or relating to resinous compositions
Filed: 1945-03-26
Abstract: A liquid composition capable of being polymerized into a thermoset resinous product comprises a solution in a liquid vinyl monomer of the reaction product of a non-frosting mixture of oils composed of a hydroxylated unsaturated fatty acid ester of a polyhydric alcohol and a glyceryl ester of another fatty acid, with at least a molar equivalent of the esters of an ethylene a -b -dicarboxylic acid or its anhydride.  Non-frosting oils may be used alone, or if frosting oils are present not less than 15 per cent of the mixture is composed of hydroxylated unsaturated oil, e.g. castor oil.  Strongly frosting oils, e.g. tung, oiticica, may be used with large amounts, e.g. 20 per cent, of castor oil.  Other suitable hydroxylated unsaturated oils are the esters of ricinoleic acid and ethylene or propylene glycol and pentaerythritol.  Admixed with these oils may be vegetable oils, esters of hydroxylated fatty acids, e.g. polyhydric alcohol esters of hydroxy stearic acid, and drying, semi-drying, and non-drying oils, e.g. linseed, tung, hemp seed, poppy seed, sunflower, walnut, oiticica, corn, cotton seed, pumpkin seed, sesame, soya bean, peanut and olive oils.  The preferred dicarboxylic acid compound is maleic anhydride, others specified are citraconic and chlor-maleic anhydrides.  Satisfactory liquid vinyl monomers are styrene, p-methyl styrene, p-chlor styrene, a -methyl styrene, a -p-dimethyl styrene, vinyl acetate, methyl vinyl ketone, acrylic nitrile, methyl methacrylate and diallyl phthalate.  Inhibitors, e.g. hydroquinone, may be added to the liquid composition and, if desired, finely-divided mica, asbestos, silica and powdered glass and fireproofing compounds, e.g. hexachlordiphenyl, tetrachlordifluoroethane and fluorinated diphenyl.  Thermoset resinous copolymers obtained by heating the solutions, preferably with addition of a polymerization catalyst, e.g. a peroxide or ozonide, have improved electrical properties, are not swelled by p oils and hydrocarbons and become elastic on heating.  They are useful for impregnating materials subject to thermal expansion, e.g. electric motor coils, wire enamels, tapes.  Laminated materials are prepared by heating under pressure sheets of paper, cotton cloth and asbestos and glass fabrics impregnated with the solutions (see Group VIII).

Title: Improved means for opening and closing gates
IPC: E05F13/02
Filed: 1930-03-08
Abstract: 342,182. Operating gates. COATES, E., Albion, Winslow Road, Padbury, near Buckingham. March 8, 1930, No. 7650. [Classes 44, 65 (i) and 65 (ii).] In an arrangement for opening a gate from a distance on one side and closing it from the other, the upper end of the heel-post 29 of the gate, Figs. 1 and 2, is pivoted at 28 to a short link 25 which is pivoted to one end of a lever 10 mounted on a pin 8 fixed to the gatepost 2. At the other end of the lever 10 is pivoted a short lever 16, to one end of which are connected the operating chains 22, of which the free ends pass through posts 23 at a distance on each side of the gate. Connected to the other end of the lever 16 by a chain 15 is a bolt 14 which is normally held in engagement with a notch in a fitting 4, fixed to the top of the gatepost 2, by a spring 13; the gate cannot therefore be opened by lateral pressure at the top of the heelpost 29. When either of the chains 22 is pulled, the bolt 14 is withdrawn by movement of the lever 16, and lever 10 is then rotated about the pin 8, bringing the gate pivot 28 nearer to the post 2 and moving it to one side of the lower pivot 46, thus raising the latch end of the gate to free the latch and tilting the heel-post 29 so that the gate swings open by its own weight and is held by a catch at the side of the road. When the other chain is pulled, the latch end of the gate is again raised, to free it from the roadside holder, and the member 29 is tilted to cause the gate to swing to its closed position, where it is held by the latch. The gate may be operated by hand in the ordinary way. Door holders. The holder at the side of the road comprises a member 42, Fig. 4, pivoted at 43 to a short post 41. The member 42 is rotated downwards by the gate passing over it in opening, but the gate cannot return owing to the member 42 meeting the stop 44. Lift latches; striking plates. The latch fitting on the gatepost 1 comprises two plates 36 to which are pivoted two members 40, Fig. 3, which allow the member 33, pivoted on the gate, to pass when the gate closes, but prevent it from returning by engaging the block 37 which separates the plates 36. The pivoted members 40 may be dispensed with, the latch 33 being made to ride over the plates 36 into the notches 38 in the plates.
