Title: Shaft furnace and method of firing granular material therein
IPC: F27B1/04
Filed: 1951-01-30
Abstract: 693,994. Shaft furnaces. SEEGER, G. Jan. 30, 1951 [Feb. 4, 1950; Jan 19, 1951], No. 2329/51. Class 51(ii) A rectangular shaft furnace for firing or sintering materials such as limestone, magnesite, chamotte or lodestone comprises a preheating section I, a firing section II and a cooling section III through all of which gases traverse the charge material on the cross-draught principle, charging arrangements being such that graded material fed through a vibrating screen 9. shoots 10 and open slide valves 7 fills the upper part of chambers 11, 12 and 13 defined by partitions 6, after which the slide valves 7 are closed, the slide valves 8 opened, and the charge material falls into the shaft disposed in streams of successively smaller particle size, the largest pieces lying adjacent the side from which the heating or cooling gases enter. Partitions 14 divide the lower end of the shaft into chambers corresponding with the upper ones, each chamber being discharged by a separate endless conveyer 15 into a space closed by alternately operated slide valves 16 and 17. Heated air from the cooling zone III may be used either to preheat the charge in the zone I or as combustion air to produce hot gases for use in the firing zone II. In a modification Fig. 2 air enters the cooling zone at 20 and passes successively across the shaft at III into a chamber 21, through a duct 22 into a combustion chamber 23, across the shaft at II into a chamber 24, through a duct 25 into a chamber 26 and finally across the shaft at I to a fan 27. Waste gases from the chamber 24 may be returned directly to the combustion chamber 23. The lower charge compartments are discharged by reciprocating rams 18 sliding over a baseplate 19. In a further modification Fig. 3 (not shown) three furnaces are placed side by side and are interconnected at increasing levels from right to left so that waste gases from the extreme left furnace pass to the preheating section 'of the middle furnace and preheated air from the extreme left furnace passes through the firing section of the middle furnace into the preheating section of the furnace on the extreme right. A final modification Fig. 4 (not shown) has the shaft widened at the point of entry to the firing zone to prevent the blocking of the inlet slots by the charge material.

Title: Reaction products and compositions prepared therefrom
IPC: C08L25/14
Filed: 1957-01-23
Abstract: A plasticizer for vinyl halide resins comprises a water-insoluble simultaneous polymerization and reaction product between (a) styrene and/or alkyl esters of acrylic and/or methacrylic acids containing 2 to 12 carbon atoms in the alkyl group, and (b) an ester of an aliphatic carboxylic acid which contains 11 to 22 carbon atoms in the acid moiety and 1 to 3 epoxy groups or 1 to 3 double bonds which are afterwards converted to epoxy groups.  The epoxy ester is made from the corresponding unsaturated ester and may be epoxidized, e.g. with performic or peracetic acid, before or after reaction with the monomer.  The unsaturated ester may be a naturally occurring oil ester e.g. soybean, corn, cottonseed, safflower, sunflower, sesame, peanut, walnut, poppyseed, linseed or perilla oil or may be derived from (a) saturated alcohols such as methyl, ethyl, isopropyl, t-butyl, n-hexyl, 2-ethylbutyl, noctyl, 2-ethylhexyl, t-octyl, lauryl, octadecyl, cyclohexyl or benzyl alcohols; ethylene, diethylene or 1,2 propylene glycol, 2-ethylhexanediol-1,3, butanediol-1,3, butanediol-1,4, dodecanediol-1,12, glycerol or pentaerythritol; and (b) unsaturated acids such as undecylinic, myristolenic, oleic, linoleic, linolenic, petroselic or erucic acids. The acrylic or methacrylic monomer may be the ethyl, propyl, butyl, amyl, hexyl, 2-ethylhexyl, octyl, decyl or lauryl esters of acrylic or methacrylic acids.  The polymerization reaction may be facilitated by heat and a conventional catalyst e.g. azodiisobutyronitrile, azodiisobutyramide, dimethyl-, diethyl- or dibutyl azodiisobutyrate, azobis (alpha-methyl-butyronitrile), dimethyl azobismethylvalerate or benzoyl, acetyl, lauroyl, t - butyl or stearoyl peroxides, cumene hydroperoxide or t-butyl peracetate or perbenzoate.  The vinyl halide resins which may be plasticized by the above products may be polymers of vinyl chloride or bromide or copolymers of these with e.g. vinyl acetate or propionate, vinylidene chloride, ethyl acrylate or methyl methacrylate.  Other modifiers such as fillers, dyes, pigments, extenders, stabilizers or other plasticizers may also be incorporated into the plasticized resin.

Patent GB-600909-A (GB)
Title: Improvements in the production of piezo-electric crystals
IPC: H01L41/22
Filed: 1944-02-11
Abstract: 600,909. Piezo-electric crystals. BENDIX AVIATION CORPORATION. Feb. 11, 1944, No. 2588. Convention date, Oct. 6, 1942. Addition to 600,190. [Class 40 (v)] [Also in Group XX] The method of manufacturing piezo-electric crystals described in the parent Specification is modified by directing a plurality of very small beams of light against one face of a slab of piezo-electric material, such as quartz, orienting the slab with the light patterns produced in the energent face of the slab as a guide, and marking the slab with a guide line making a predetermined angle with a line determined by the patterns. As shown, quartz slabs 7 prepared by being cut out of mother crystal, using cutting planes spaced by about three-quarters of an inch parallel to the Y and Z axes, etched for a period of three to four hours in a 48 per cent solution of hydrofluoric acid, washed and dried, are laid upon a table 2 with the negative end of the X axis towards the observer, whereby parallelogram-shaped light patterns are produced in the emergent face 14. Two or more pinholes are provided in the table 2 above a lamp in the box 1, e.g. two pinholes of .013 inches diameter and spaced apart by .375 inches along a line parallel to a bar 5, each pinhole resulting in a parallelogram light pattern 15, Figs. 4 and 5. In Fig. 4, the slab 7 is incorrectly positioned on the table, a correcting rotation of the slab resulting in a rotation of each parallelogram about its centre 16, corresponding to the pinhole, until the two parallelograms are aligned as in Fig. 5. The slab is then scribed to indicate cutting planes for producing the bar stock for the manufacture of crystal blanks, a triangular guide 8 being used for this purpose. The guide 8 is secured to a base 9 which, if B.T. bar stock is to be cut, is rested against the B.T. guide 5. The edge R or L is used accordingly as the quartz is right-handed or left-handed, this being indicated by the slope of the short sides of the parallelogram when the long sides are parallel to the guide 5. If the short sides slope to the right, the edge R is used, and if to the left, the side L is used. If A.T. bar stock is required, a triangle 8 of apex angle 5 degrees 44 minutes, as against 3 degrees 58 minutes for B.T. bar stock, is used with the guide bar 6 as the datum line. The images 15.should overlap slightly for the best results to be obtained, and a pinhole separation' of approximately one-half of the thickness of the test slabs is stated to be satisfactory.

Patent GB-828989-A (GB)
Title: Improvements in and relating to the polymerisation of acetylenically unsaturated hydrocarbons
IPC: C08F2/00
Filed: 1958-01-28
Abstract: Acetylenically unsaturated hydrocarbons are polymerized, or copolymerized with ethylenic hydrocarbons, by contacting with a suspension of a reaction product of aluminium chloride, titanium tetrachloride and an alkali metal in an organic solvent at a pressure below 100 atmospheres and a temperature below 120 DEG  C. The molar ratio of alkali metal to AlCl3 is preferably 0.1 to 1.5:1, and reaction is first effected between these components in an oxygen-free atmosphere preferably in a liquid hydrocarbon such as heptane.  The TiCl4 is added before or during the introduction of the monomer.  The process is improved by the addition to the suspension of an anhydrous, finely-divided solid substance which is insoluble in the medium, e.g. halides of alkali and alkaline earth metals, carborundum and glass powders, sand, polyethylene, polypropylene, polyvinyl chloride and acetate and butadiene-styrene copolymers.  The water-soluble substances may be removed from the polymer by washing with water; the others, by adding further solvent, heating to dissolve the polymer and filtering.  The organic solvent is preferably an aliphatic hydrocarbon, e.g. heptane, octane or petroleum distillates.  The example describes the preparation of an acetylene polymer which did not melt at 300 DEG  C. but burned. Specification 824,451 is referred to.
