Title: Improvements in or relating to the manufacture of refractory hard metal material
IPC: C01B31/30
Filed: 1963-01-29
Abstract: A high-melting refractory hard metal material is manufactured by mixing suitable reactants, forming into a hollow-shaped mass, e.g. a cylinder, with a central passageway having cross-sectional area 0.04-0.75 that of the total; passing it through a heating zone, and removing the products.  The mixture may be composed of a metal (or boron) oxide and a carbonaceous material to give a carbide; or with boric oxide, boric acid, or boron carbide in addition to give a boride (of at least 95% purity).  Boric oxide is used in excess, e.g. 5%, to provide for loss by volatilization, and any remaining is removed after reaction by leaching with water.  A binder, e.g. kerosene, in which the reactants are not soluble, may be included. The mixture may be extruded, ram packed, tamped, or compacted by vibration, into the hollow shape, which is placed in a graphite boat or tubular sleeve, passed through a horizontal, vertical, or inclined tube furnace at 1850-2250 DEG  C and cooled, e.g. in an inert atmosphere.  Gaseous products such as CO escape through the central passageway.  The process may be operated continuously.  Hard metal materials specified are carbides and borides of Ti, Zr, Nb, Ta and Hf, CrB2, and B4C.

Title: Improvements in electric heaters for water and other liquids
IPC: F24H1/10
Filed: 1944-02-29
Abstract: 577,118. Electrically heating liquids. KRIWACZEK, 0., and KAYE, L. Feb. 29, 1944, No. 3714. [Class 39 (iii)] [Also in Group XXXVII] The heating device of a water &c. heater delivering hot or cold liquid is switched on automatically by the flow of liquid through the heater when (a) its discharge is permitted by a control valve and (b) a selector member is set to the "hot" position. In the example, liquid is admitted through adaptor 5 and passes upwards in a helical path defined by the bare resistance winding 17 and the cylindrical walls 15, 16 of porcelain &c. Thence it flows, as indicated by arrows, via valve 11 and out through spout 9, and, in doing so carries with it a disk 18 connected by rod 19 to a hinged arm 23, 29. With selector lever 10 in the " hot " position and valve 11 open the arm 29 operates an electrical switch device so that the heating winding can be energized only when liquid is discharging at 9. Cold liquid is obtained by moving selector lever 10 horizontally so that arm 29 clears the plunger 24 of the switch 25. An alternative connection is provided by replacing adaptor 5 by plug 8, the liquid entering vertically instead of hor.zontally. Hence the heater may replace any type of existing tap.

Patent GB-490905-A (GB)
Title: Improvements in latex compositions
IPC: C08K5/39
Filed: 1938-02-08
Abstract: A process for vulcanizing latex or latex compositions consists in incorporating, as an accelerator, in a vulcanizable latex or latex composition, an alkali-metal or ammonium salt of an N-aralkyl-substituted dithiocarbamic acid capable of having its accelerating action arrested by ammonia, deactivating the accelerator by ammonia and thereafter removing or neutralizing the ammonia to allow of vulcanization.  The ammonia may be replaced by a volatile substituted ammonia in which one of the H atoms has been replaced by a hydrocarbon radical, preferably an alkyl radical, e.g. methylamine. The vulcanization of the rubber in the latex state can be checked at the desired stage by reintroducing ammonia or substituted ammonia. For example latex containing ammonia or a substituted ammonia, vulcanizing agents and accelerator, may have the ammonia or substituted ammonia content reduced to about ,1 per cent, by aeration or neutralization with formaldehyde, thereby allowing vulcanization to proceed at room temperature or higher, and then by reintroducing ammonia or substituted ammonia into the latex before the vulcanization of the rubber globules is completed, a partly vulcanized latex is obtained.  The accelerators are of the general formula <FORM:0490905/V/1> where M is an alkali-metal or ammonium radical which in the case of ammonium may be substituted, for example dibenzylammonium-N-dibenzyl-dithiocarbamate.  They may be used in combination with accelerators of the thiazole type, e.g. the zinc salt of mercaptobenzothiazole, the combination being similarly deactivated by ammonia or substituted ammonia.  U.S.A. Specification 1,995,859 is referred to.

Patent GB-849780-A (GB)
Title: Improved method for imparting a stretch nature to cellulose ester yarn or tow
IPC: D02G1/10
Filed: 1957-02-07
Abstract: Permanent stretch properties are imparted to a cellulose ester, e.g. acetate (propionate or butyrate) or triacetate, yarn or tow by treating the yarn &c. to increase its elongation at break followed by passage, at elevated temperature (360 DEG -440 DEG F.) through an angular path about the edge of a blade member and under a tension (0,05-0,4 grms per denier) sufficient to elongate the yarn.  The yarn is then cooled as rapidly as possible to a temperature at least 150 DEG F. below the temperature at which it passed about the edge. Latent stretch, i.e. curled deformations, may be developed by reheating the yarn, as by passage through an aqueous bath, steam or dry heat, to a temperature of 120 DEG -140 DEG F. for a few seconds in untensioned condition.  The yarn (as a running length or a wound package) may be treated to increase its elongation at break by immersion or forced circulation for a period of 15 minutes to 16 hours with an aqueous solution of one or more non-oxidising inorganic acids, e.g. sulphuric and hydrochloric acids, or salts thereof with polyvalent metals, e.g. zinc, cupric, aluminium, stannic chloride and cadmium sulphate, or mixtures thereof : the solution may contain wetting and/or swelling agent such as ethylene glycol dimethyl ether and/or organic solvent for removal of antistatic agent.  The liquid treatment may be followed by washing and/or rinsing in an acid-neutralising solution and drying.  Specification 558,298 is referred to.

Title: An improved method of and apparatus for producing thin-walled vessels from thermoplastic material
Inventor: LANG THEOBALD OTTO
IPC: B29C49/14
Filed: 1956-02-11
Abstract: 791,097. Moulding plastic hollow-ware. RYBURN ENGINEERING CO., Ltd. Feb. 11, 1956, No. 4362/56. Class 87(2). Hollow articles such as thin-walled cups are moulded from heated foil 4 of thermoplastic material which is placed in front of the opening of a mould 2, pressed by the edge 15 of the mould against a table 1 and rested on by a plunger 6 which has a shape corresponding to that of the bottom of the article to be produced, compressed air being forced through a pipe 16 and urging into the mould the part of the foil located in the opening thereof, at the same time forcing back the plunger 6 against a spring 10 or against a weight. Two or more series of hollow articles may be moulded simultaneously side by side from the same foil. The foil 4 is drawn (from left to right in Fig. 1), between a roller 22 and the peripheral portion 24 of a driven roller 21. When the smaller radial periphery 23 comes opposite the roller 22 the foil is stationary and a pressure member 20, driven, e.g., by compressed air, moves down a part 9 carrying the moulds and the foil is clamped between the edge 15 and an annular surface 14. This surface 14 surrounds a recess 27 which itself surrounds a central supporting surface 13 with a recess 28 into which the pipe 16 opens. A projection 29 on the plunger 6 forms a recess in the foil which is immediately cooled hard whereby, as the plunger is forced back, the foil is centred thereon. When the plunger 6 reaches a stop 11 the compressed air is cut off and the moulds are raised by the member 20, the spring 10 causing the plunger 6 to act as an ejector. The larger radial periphery on the roller 21 then comes opposite the roller 22 and draws away the thermoplastic foil with completed vessels, e.g., 30, 31, formed in it. On the next downward movement a knife 25 on the part 9 severs the foil. Additionally, or instead of, the knife 25 a stamping device may be fitted to remove the vessels from the remainder of the foil. A retarding valve functions to delay pressure in the pipe 16 until the foil is clamped and may also act as a throttling valve to control the wall thickness of the moulded article.
