Title: Improvements in or relating to apparatus for measuring the force exerted by a hydraulic press
IPC: G01L5/00
Filed: 1957-02-04
Abstract: 827,226. Dynamometers, testing physical qualities of materials, pressure gauges. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 4, 1957 [Feb. 2, 1956], No. 3828/57. Class 106 (2). [Also in Group XXIX] Apparatus for measuring the force exerted by an hydraulic press 1, 2 comprises an auxiliary cylinder 7, connected to a pressure fluid system 50, and an auxiliary plunger 6 arranged for displacement by the force P exerted by the press 1, 2, a valve 8 being provided to regulate the liquid flow to the interior 10 of the cylinder 7 in accordance with the force exerted by the press 1, 2. A pipe 11 conveys liquid under pressure to the interior 10 of the cylinder 7, and a pipe 12 connects this interior to a liquid pressure gauge 13-18. The cylinder 1 of the press rests on the auxiliary plunger 6 and hence applies a force Q to it. If the force Q increases, the auxiliary plunger 6 will be displaced downwards, valve 8 will open further and the pressure of liquid in the interior 10 will increase to balance the new force Q. The reverse process takes place if the force Q decreases. The area of plunger 6 is slightly greater than that of plunger 2, so that, despite the loss of pressure due to valve 8, the pressure in the interior 10 can balance the force Q, if the liquid is applied from the same source as that operating the press 1, 2. The apparatus may be used to measure the force exerted in compression tests of materials or by use of the frame 21 and coupling 22, the force exerted in tension tests. It is stated that allowing liquid to leak around the sides of the plunger 6 and from the cylinder 13 of the gauge permits greater accuracy than does the usual closed system. The pressure gauge consists of a plunger 14 in a cylinder 13 acted on by the fluid and connected by a linkwork 15 with a pivoted lever 17 carrying a weight 16, lever 17 being connected indirectly with an indicator 18.
Patent GB-680996-A (GB)
Title: Modified alkyd resins
IPC: C08G63/553
Filed: 1949-02-11
Abstract: Modified alkyds are prepared from a polyhydric alcohol with at least three hydroxyl groups, an aliphatic polycarboxylic acid with a chain of at least 3 carbon atoms between two carboxylic groups, a natural resin acid and a drying or semi-drying oil fatty acid, the proportions by weight of the ingredients based on the weight of product being at least 10 per cent for the polycarboxylic acid and being greater in the case of both the resinic acid and the monobasic acid.  In preferred alkyds the proportions are 10-20 per cent polycarboxylic acid; 35-45 per cent natural resin acid and 30-40 per cent fatty acid.  Polyhydric alcohols specified are glycerol, erythritol, sorbitol, pentaerythritol, di- and poly-pentaerythritol. Polybasic acids are glutaric, adipic, methyladipic, pimelic, sebacic or the adducts produced from an aliphatic a b -unsaturated polycarboxylic compound, e.g. maleic anhydride and fatty acids with conjugated double bonds, e.g. ricinenic acid, or eleostearic acid or the corresponding oils. The chain portion of the adduct not between carboxylic groups is counted as fatty acid for the purposes of the invention.  A tall oil fraction containing abietic acid and rather less fatty acids may provide both of the other ingredients.  Rosin, manila or congo copal may also be used.  The fatty acids may be replaced by the oils after alcoholysis with the polyhydric alcohol used. Products are soluble in petroleum hydrocarbons and with added driers yield hard, elastic films.  Pigments may be added.  The alkyd may be mixed with other alkyds.  In examples: (1) tall oil (60 per cent abietic acid and 40 per cent fatty acids), pentaerythritol and adipic acid are heated together until the product has an acid number of about 10.  Product may be dissolved in mineral spirits and mixed with zinc oxide.  The pentaerythritol and tall oil may first be reacted and the adipic acid then added.  (2) Chinawood oil is heated with maleic anhydride, and rosin, linseed oil, pentaerythritol and glycerol are added and the mixture heated until the acid number is 15 or less.

Title: Improvements in methods of and means for the heat treatment of solid bodies
Inventor: AMSTEIN EDMUND HOLLIE
IPC: C21D1/53
Filed: 1950-01-06
Abstract: A solid body, e.g. of metal or glass, is heat treated by immersion in a fluidized powdered or granular material containing a source at a different temperature from that of the body, then removal from the material after a pre-determined transmission of heat has taken place. A layer of granular material is fluidized in an iron tank by streams of compressed gas escaping upwards from the tank bottom which is porous, being of porcelain or brick or of wire cloth which has been subjected to a rolling operation as in Specification 709,265, [Group XXX].  Heat is supplied by electric resistance heaters at least partly immersed in the fluidized bed and the gas may be pre-heated. If the gas is selected to provide a controlled atmosphere it may be circulated in a closed path. The granular material is alumina or ground crystalline material such as calcium fluoride (fluorspar), silica or sand and is of 30-100 microns particle size.  A metal such as an aluminium-manganese alloy, to be annealed is plunged and suspended in the fluidized material maintained at 450 DEG  C.  The vertical walls of the tank may be heated or cooled.  By use of this method a body may be heated for hot-working, for relieving stresses or for modifying its structure and constitution or it may be cooled or quenched.  For example, cold-worked brass or copper is annealed, aluminium alloys are solution treated, aluminium is degassed, steels are carburized and carbon steels are quenched p  from above 760 DEG C.  Aluminium-magnesium-silicon alloy, H.S.10, is heat treated and, after water-quenching, aged in fluidized material.  The gas may react with the substance of the treated body and the granular material may be such that it acts chemically on the body in the presence of a selected gas or vapour introduced with, or as, the fluidizing medium. Hydrogen may be used and nitralloy steel may be nitrided in alumina fluidized by ammonia.
