IPC: B02C9/00
Filed: 1930-07-28
Abstract: 359,939. Impact pulverizers. WISLER, L. A., 62, Rue des Marais, Paris. July 28, 1930, No. 22719. Convention date, Aug. 13, 1929. [Class 59.] A machine that is provided with interchangeable parts so that it may, as desired, be used for the slicing up of roots and tubers, the decorticating, crushing and grinding or milling of cereals and the breaking up of oil cakes comprises a frame 1 within which an electric motor 2 is supported by radial arms 3 extending from a ring member 4, the motor shaft 20 being adapted to have fitted thereon a plate 18 the type of which varies with the nature of the work to be effected. In the form shown, which is suitable for the decortication and crushing of cereals, lentils and the like, the plate is provided with fingers 21 which move in a circular crenelated groove 22 formed in the lower part of a co-operating frame 13 adapted to be secured on the upper part of the main frame 1 by bolts 15. A hopper 14 constituting the upper part of the frame 13 leads to a central reduced passage in which a cylindrical sleeve 23 having a serrated lower edge'26 is arranged, this sleeve being adjustable vertically by a hand operated crank 25 to control the flow of material to the treatment groove 22. The treated material falls through the annular space between the motor and the frame into a container that is secured to the frame by clamps S. The plate 18 may be provided on its periphery with notches that serve to sift the material passing the plate, the blades at the sides of the notches being displaced relatively to the general plane of the plate. In the plate for breaking oilcakes the upper face is provided with radial notched blades adapted to strike the lower edge of the oil cakes that are arranged vertically in an opening in the corresponding upper frame 13.

Title: Method of making a magnesium-base alloy containing aluminium and zinc
IPC: C22C23/04
Filed: 1956-07-24
Abstract: Magnesium-base alloy ingot is made by dispersing 0.3-0.6 per cent of Zr in a first batch of molten Mg and then dispersing an amount of Al equal to about 3-5 per cent of the weight of the Zr added, settling the so treated melt, alloying 5-7 per cent of Al and 1.5-3 per cent of Zn with a second batch of molten Mg, blending substantially equal weights of supernatent portions of the two melts and casting the blend to give ingots containing 2.5-3.5 per cent Al and 0.75-1.5 per cent Zn.  The Zr may be added as a master alloy of Mg with 30 per cent Zr or as a fused mixture of equal parts of ZrCl4 and KCl.  The second batch of alloy may be treated with a carbonaceous grain refining material prior to mixing with the first batch.  The blended alloy may be treated with up to 0.04 per cent Ca, which may be added as an alloy of 80 per cent Ca and 20 per cent Mg, and with a small amount of halogenated carbonaceous material such as polytetrafluoroethylene before being cast.  Mn, e.g. in amount of 0.25 per cent, may also be present in the second batch of alloy.

Title: Apparatus for classifying small time intervals
Inventor: FORMBY JOHN ALBERT
IPC: G01P3/68
Filed: 1953-08-19
Abstract: 772,838. Photo-electric speed indicators. FORMBY & CO., Ltd., J. Nov. 18, 1954 [Aug. 19, 1953], No. 22922/53. Class 40 (3). Apparatus for effecting control if two electrical signals are spaced by more or less than a predetermined time comprises a timing device started by the first signal and serving to gate the second signal to effect a control according as the appropriate period has or has not elapsed. The invention is described with reference to determining whether a car breaks two spaced beams of light in less than a predetermined time. As shown, breaking of the first beam causes photo multiplier 4 to unblock an amplifying tube 8 which through a transducer 13 in its cathode circuit marks a continuously rotating magnetic drum and at the same time changes the state of a bistable pair 9, 10 so that tube 10 is cut off. After a period determined by the speed of rotation of the magnetic drum a pick-up produces a pulse as a result of the passage of the mark on the drum beneath and restores the bi-stable circuit. If photo-cell 5 has meanwhile produced a pulse as a result of the passage of the car in front of it, tube 19 is triggered and relays 26 and 28 operated. If the interruption takes place after the bi-stable circuit is reset no operation of these relays takes place. By interchanging the outputs of tubes 18 and 21 the apparatus will indicate if a speed is below that for which the magnetic drum is set. The time interval may be varied by moving the pick-up lead relative to the recording lead.

Abstract: The invention comprises mixed sulphite diesters of an acyclic alkynyl alcohol and a saturated aliphatic alcohol or phenol, particularly diesters of the formula: <FORM:0968058/C1/1> wherein R is an alkyl, aralkyl, cyanoalkyl, haloalkyl, carbalkoxyalkyl aryl, alkaryl or haloaryl radical and R1 is an acyclic-alkynyl radical. The esters are prepared from the chlorosulphinate of the alcohol or phenol, by treatment in a solvent, e.g. benzene, xylene or solvent naphtha, with the alkynyl alcohol in the presence of an HCl acceptor, e.g. pyridine, dimethylaniline or trimethylamine, at between -10 DEG  and 50 DEG C. The chlorosulphinate is prepared by treatment of alcohol or phenol with thionyl chloride at between -5 DEG  and 30 DEG C.  These compounds may be used as insecticides. (see Division A5).ALSO:Insecticidal compositions contain as the active ingredients mixed sulphite esters of an acyclic alkynyl alcohol and a saturated aliphatic alcohol or phenol, particularly diesters of the general formula <FORM:0968058/A5-A6/1> wherein R is an alkyl, cyanoalkyl haloalkyl, carbalkoxy alkyl, aryl, aralkyl, alkaryl or haloaryl radical and R1 is an acyclic-alkynyl radical (see Division C2).  The chemicals may be applied as dusts mixed with powdered solid carriers, for example mica, talc, pyrophyllite and clays; as liquids or sprays when dissolved in a solvent, for example acetone, benzene or kerosene, or as aerosol sprays when dissolved directly in an aerosol carrier.  They are preferably used as aqueous emulsions containing an anionic, non-ionic or cationic surface active dispersing agent or as aqueous suspensions containing solid powder carriers and dispersing agents.

Patent GB-360944-A (GB)
Title: Improvements in the production of coatings
IPC: B05D7/26
Filed: 1930-08-07
Abstract: A process for coating surfaces consists in applying two or more layers of a composition containing an artificial resin capable of being hardened, in which the outer layer contains a hardening agent rendering the coating resistant, and one or more of the inner layers contain an inorganic softening agent rendering the coating elastic. As softening agents graphite, pulverized asbestos, soot, talc or mica may be used, and as hardening agents metal oxides or finely divided metals such as aluminium, titanium, zinc or ferric oxides, or aluminium or copper bronze.  The outer coating may be rendered acid-proof by using pulverized quartz, silicon or lead oxides. Pigments may be added.  A composition for the inner layer may be made by mixing graphite with alcohol in a colloid mill and adding an aqueous suspension of a phenol-aldehyde resin or a glyptal resin containing linoleic acid. A hardening agent such as red lead may also be incorporated.  An outer-resistant coating composition is made by mixing powdered silicon or lead oxide with a phenol aldehyde resin and alcohol, and when the coating is dry, it is hardened by heating first at 100 DEG  C. by steam and then at 160-170 DEG  C.  The process may be used to coat wood surfaces, or to render rust-proof pipes or vessels made of iron, copper, aluminium, or magnesium or alloys thereof. The compositions may be applied by brushing, dipping or spraying.  The Provisional Specification describes also the use of a single coating in which both softening and hardening agents are incorporated.
