Title: Improvements in polyester compositions
IPC: C08L75/06
Filed: 1949-05-30
Abstract: Curable resinous compositions comprise an organic polyisocyanate modified polyester in uniform admixture with partially hydrolysed leather, i.e. leather which is heated in the presence of water till its fibrous nature disappears; the polyester being formed from a glycol and a mixture of aliphatic and aromatic dicarboxylic acids in the molecular proportions 90-65 to 10-35.  Hydrolysed leather, formed by working leather scrap into a slurry with hot or cold water and then boiling the slurry, may be worked into the modified polyester or alternatively leather scrap, dry or as a slurry, may be compounded with the modified polyester and the hydrolysis effected in situ. Curing of the materials may be effected by heating in presence of formaldehyde, a formaldehyde liberating substance or a dichromate together with an acid or a material developing acidity under the reaction conditions.  Additional ingredients are fillers, other plastic materials, detackifying agents, plasticizers, softening agents, dispersing agents, stabilizers, antioxidants and pigments. Applications of the material are for petrol and/or oil resistant articles, e.g. gaskets, packings, hose and diaphragms for pumps; for rollers, blankets and stereos for use in the printing industry; and for flexible containers, balls for games and coated or laminated fabrics, e.g. protective clothing water-proof garments, shoe uppers, slippers, conveyer belting, upholstery, leather-cloth and floor coverings.  Specified glycols are ethylene-, diethylene-, trimethylene-, pentamethylene-, hexamethylene- and decamethylene-glycol, and 1 : 12-octadecanediol and pentaglycol. Specified aliphatic acids are malonic, maleic, fumaric, succinic, glutaric, suberic, azelaic, beta-methyladipic, adipic, pimelic, sebacic, undecanedioic, and brassylic.  Specified aromatic acids are o-phthalic, iso-phthalic, terephthalic, hexahydroterephthalic and p - phenylenediacetic.  Many polyisocyanates are specified.  In an example, a polyester is made by heating the reaction products of (a) adipic acid with ethylene glycol, and (b) dimethyl terephthalate with ethylene glycol in presence of litharge.  It is modified by heating with hexamethylene diisocyanate and compounded on a rubber mill, with rollers heated to 50 DEG  C., with a pulp made by hydrolysing a vegetable tanned leather.  Milling is continued till the composition is dried and the composition mixed with acetone, benzene, toluene, and ethyl alcohol and compounded with hexamethylolmelamine hexamethyl ether, 2 : 4-dichloro-1-naphthol, tricresyl phosphate, yellow chrome pigment and copper phthalocyanine pigment.  The mix is then used to treat a cotton fabric.  Specification 583,862 is referred to.

Abstract: 1,171,115. Centrifugal pumps. E. H. PRIEST and G.M. PRIEST. Nov.14, 1966 [Nov. 12, 1965], No.14576/68. Divided out of 1,171,114. Heading F1C. [Also in Division F2] In a heat-transfer system for pumping inflammable heat-transfer liquids whose temperature differs substantially from the ambient temperature, a temperature barrier section 5a, Fig. 1, if substantial length is arranged between the pump 4 and a seal 8 to maintain the seal at a temperature suitable for effective operation. The barrier section may be cooled by a heat exchanger, Figs.3e and 3g (not shown), or via fins arranged externally thereon, Fig.3f (not shown). Cooling in the barrier section may be improved by a pair of discs (9a, Fig.3a, not shown), mounted on the shaft (5) therein, or by a pair of impellers (9b, Fig. 3b, not shown), which create opposite or unidirectional axial pressures. The seal 8 is in communication with the liquid being pumped either directly, or indirectly through another liquid. The barrier section may contain a pair of axially spaced stationary discs surrounding the shaft 5 with small clearance to reduce movement of the liquid in the barrier section, Fig.3c (not shown). Gland seals may be provided at or near both ends of the barrier section, Figs.3d and 3e (not shown). When a seal is provided between the barrier section and the pump, some fluid communication is still provided therebetween. The end of the barrier section adjacent the pump may open directly into the pump casing or, as shown, may be provided with a shaft bearing. The pump may be driven by a hydraulic motor 3 receiving driving liquid from an auxiliary pump 2 via a heater or cooler 6. The driving liquid is preferably the same as the heat-transfer liquid, and may be returned from the motor to the pump 2 via the barrier section. A pipe 7 accommodates expansion and contraction of the driving liquid. Alternatively, the pump 4 may be driven by an electric motor (21, Fig.2 not shown), via a shaft coupling (24) contained in a separate housing (23) which may receive fluid at a controlled temperature.

Title: Pneumatic conveying system
IPC: B65G53/06
Filed: 1953-05-27
Abstract: 725,388. Pneumatic conveyers. BAKER PERKINS, Ltd. May 27, 1953 [June 5, 1952], No. 14738/53. Class 78 (1). In a pneumatic conveying system particularly for use in conveying flour from a bin 2, or any one of a series of bins, to a dough mixer, or any one of a series of mixers 5, 6, and delivering a predetermined weight to the mixer, a weighing scale hopper 3 or 4 is positioned over each mixer and the conveying system is in the form of a closed loop 23, 27 which starts and ends at a bin. The scale hoppers are connected to the loop by short branch lines 30, 33 controlled by valves 24, 26 which may be actuated to divert flour from the conveyer line. Flour is tipped into a blender I and is fed therefrom by a motordriven paddle-wheel type feeder 12 into a conduit 13 along which it is conveyed by compressed air supplied by a blower 9 to a separator 14. The flour passes from the separator to a motor-driven sifter 15 which delivers it to the storage bin 2. The air discharged from the separator 14 passes through a pipe 20 to a dustcollecting conduit 18 which is connected to a centrifugal separator 16. When the valve 10 is turned to connect the blower 9 to the pipe 21 instead of to the feeder 12, the flour delivered by the motor-driven paddle wheel feeder 22 to the conduit 23 is blown therethrough towards the mixers 5, 6 and is directed into one of them by actuating the appropriate one of the three-way valves 24, 26. These valves admit the flour to the branch lines 30, 33 respectively, which discharge tangentially into separators 31, 34 positioned on top of the hoppers 3, 4 and connected by pipes 32, 35 to the conduit 18. Shut-off valves 7, 8 are provided between the hoppers and mixers. The line 23, 27 is connected to a separator 28 mounted on the bin 2 and connected to the conduit 18. Each hopper has a movable element which, when the hopper has received a predetermined weight of flour, moves from its normal position and effects the actuation of means for moving either the valve 24 or the valve 26 to the straight-through position. In moving into this position the valve actuates means for stopping the feed of flour to the pipe 23. Means is provided also for delaying the stopping of the blower 9 until the line 23, 27 is cleared of flour, this means being responsive to the pressure of the air delivered by the blower. Further means is provided which, when the valve is in the straight-through position, prevents actuation of the valve-shifting means until the line has been cleared.

Title: An improved holder for stacks of sheets
IPC: A47K10/42
Filed: 1923-06-07
Abstract: 201,887. Independent Paper Mills, Inc., (Assignees of Arelt, C.). Aug. 5, 1922, [Convention date]. Packing towels, napkins, and toilet paper.-A holder for paper sheets such as napkins, towels, toilet paper, &c., is constructed so as to facilitate the removal of individual sheets from the top of a stack which is pressed upwards by weights. The stack is arranged in a holder 16, Fig. 4, and is formed of sheets which are staggered by placing the longitudinal axes of alternate sheets at right angles to one another. The sheets are carried on a support 18 of cruciform shape which is guided on rods 17 and is pressed upwards by chains 20 passing over sprockets 21 fixed to the casing 16. Weights 19, 19<a> shaped so as not to interfere. with the passage of the pile of sheets, act to keep the pile pressed against a detachable top 25 to the container 16. The weights are fitted with pulleys 24 which move over the guide rods 17. The centre portions c of the sheets project through an opening 26, Fig. 2, in the cover 25, and the separated sheets can be readily withdrawn by hand from the top of the pile through this opening. The cover 25 is secured in position by studs 28 which are passed through key-hole slots 27 and turned, and these studs, release locking-pawls 31 engaging ratchets 30 on the shafts of the sprockets 21 which are automatically locked to prevent the weights from raising the pile support when the cover 25 is removed. When the pile decreases to a certain extent, the weight 19<a> goes out of action by the aid of a fixed support 29 which prevents further fall of this weight. The chain 20 is detachably connected to the weight 19 bv means of loops which are received in inclined slots in headed studs 20<a> which pass through recesses in the weights, the loops being unable to leave the recesses when the studs are received into the recesses as shown in Fig. 4.

Title: Process for preparing low density gels
IPC: C01B13/14
Filed: 1955-05-24
Abstract: <PICT:0806007/III/1> An hydrogel of an inorganic oxide containing a substantial proportion of water is simultaneously dried and comminuted to form a low density, finely - divided friable gel by providing a moving body of fluidized hydrogel particles in a gaseous medium at a superatmospheric presure at a temperature above the boiling point of water at that presure, continuously introducing additional hydrogel into the body, continuously introducing additional heated gaseous fluid into the body in a plurality of high velocity streams directed inwardly into the body to produce extreme turbulence within the body a resulting attrition of the suspended particles, continuously withdrawing the fluid, water vapour, and suspended dry, comminuted particles from the body, and separating the dry particles from the suspending fluid, at a temperature above the boiling point of water.  Gels may be SiO2, Al2O3, MgO, ZnO, or Fe2O3, and silica gel, containing 60-90 per cent water, may be prepared by reacting sodium silicate solution and sulphuric acid to form a hydrosol, allowing the hydrosol to set to hydrogel, breaking up the hydrogel, washing with aqueous ammonia, and draining.  Silica gel is injected under pressure through inlet 9 into annular feed header 10 and passes thence through spaced ports 15 into circular chamber 7. Heated gas, e.g. superheated steam, or hot compressed air, enters through inlet 3 and header 4 and is discharged into chamber 7 through a plurality of spaced openings 6 in a direction tangent to a theoretical circle concentric with, but of smaller diameter than, chamber 7.  The silica gel is consequently entrained in the rotating gas to form a rotating body of suspended gel particles, and the gel is subjected to attrition by extreme turbulence, and to disintegration by flash evaporation of water. By the rotary movement finer particles move into central collector 11, where continued rotation frees the gas from the particles.  Separated particles of sizes 3-10 m  and moisture content 8 per cent collect in hopper 12, and gas and water vapour are exhausted to atmosphere through outlet 13.
