Title: Improvements in the process of manufacturing phenol-aldehyde resins or products thereof
IPC: C08G8/00
Filed: 1937-05-22
Abstract: Discolourization of phenol-aldehyde resins or products containing such resins such as lacquers, varnishes, pore-fillers or moulded objects is prevented or neutralized by reacting the liquid condensation product, in the presence or absence of a solvent, first with less than 2 per cent of nitric or nitrous acid or a nitrate or nitrite and an acid or acid salt and then with an aldehyde or amine. Colouring agents are formed which marked the discolourization.  In an example, phenol, with or without cresol, is condensed with formalin in the presence of potassium or sodium carbonate or hydroxide and the liquid dehydrated condensation product dissolved in ethyl alcohol is treated first with nitric or nitrous acid and then with furfurol. The solution, together with a hardening agent used at the time of use, is used as a coating.
Patent GB-653188-A (GB)
Title: Improvements in and relating to the extraction of protein from seeds
IPC: A23J1/14
Filed: 1948-05-27
Abstract: Vegetable proteins are extracted from protein-containing seeds by means of an aqueous alkaline liquid containing both alkali metal ions and aluminate (AlO2-) ions and having a pH value within the range of 8.5 and 11.5, the liquid extract is separated from the undissolved material and the protein in the extract precipitated by addition of an acid.  The extraction may be effected by adding an alkali metal aluminate as such to the extraction liquid or by forming such an aluminate in situ by pretreating the seeds with a solution of an aluminium salt and then adding an aqueous solution of an alkali metal hydroxide to extract the protein and to form the alkali metal aluminate in the solution by reaction between the aluminium salt and the alkali hydroxide; in the latter method, it is preferred to add a salt, such as sodium sulphate, to the pretreating solution which will increase the solubility of the protein, decrease the solubility of impurities and reduce the swelling of the final precipitate.  The alkaline extracting liquid is preferably an aqueous solution of an alkali metal hydroxide.  Also the seeds are preferably used in the finelyground oil-free condition.  Examples illustrate the extraction of protein from pea-nut meal by both of the above methods, dilute sulphuric acid being used to precipitate the protein; the same extraction in absence of the aluminate gives a darker product more susceptible to oxidation in alkaline solution. The extraction of vegetable casein from bean meal, pea meal, and castor bean meal is referred to.  According to the Provisional Specification, the extraction is effected by means of an alkaline liquid at a pH value of not less than 8.5 and in the presence of an alkali aluminate.

Title: Improvements in door closing devices
IPC: E05F3/10
Filed: 1954-05-21
Abstract: 778,850. Door-operating appliances. SCHUMACHER, O., and BIELEFELD, F., [trading as SCHUMACHER & BIELEFELD], and SASSE, G. May 21, 1954 [Oct. 28, 1953], No. 14991/54. Class 65 ( 1 [Also in Group XXXII] In a door-closer with a tension spring and an hydraulic check actuated by rotation of a shaft, motion is transmitted to the spring through a non-rigid tension element which acts at an operative radius which diminishes during opening of the door, the intermediate part of the tension element remaining free, until the element is constrained to wind around the shaft at a constant radius during the remainder of the opening. In the form shown, having two tension springs 1 adjustably attached to the casing by bolts 2 and attached to a yoke 12 guided by an arm 17, the flexible element comprises two curved links 10 attached to and arranged to wind on a cam portion 9 of the shaft 8, which has squared ends at top and bottom for engagement with the door or a lever connected to the door or frame, so that it can be used in floor or lintel without inversion, or for a door of either hand. The arrangement is such that after a predetermined movement of the door the pivot between the links 10 becomes coaxial with the shaft 8, so that the spring exerts no closing force on the door and the latter can be opened further without increasing the stress in the spring; the effect can be altered by using a link or links of different length. The piston of the check 3 is connected by a rod 4 with an arm on the shaft 8. In a simpler form only one spring is used, connected by a chain to a cam or camshaped lever on which the chain wraps itself during opening of the door, the guiding arm 17 being omitted. For swing doors the yoke 12 is connected by chains to two cam arms symmetrically placed on the shaft 8 so that the springs are tensioned by a pull on either chain, the pivot of the guide-arm 17 being adjustable for centring the door; the check piston is spring-pressed outwards and is actuated by a cam on the shaft. In a modification the spring and check are connected to members on separate shafts which are geared together. The device may be placed on the face of the door, in which case the check cylinder may be arranged vertically with the piston-rod extending upwards, avoiding the need for an oil seal. The check cylinder is preferably provided with a oneway valve, communicating with an oil reservoir, in parallel with a restricting valve which can yield under excessive pressure, the arrangement being such that the oil is passed through a filter both on entering and on leaving the cylinder so that any dirt sucked on to the filter is forced off again.

Abstract: 639,856. Tensioning and positioning weft in gripper-shuttle looms. SULZER FRERES SOC. ANON. June 6, 1947, No. 15016. Convention date, June 7, 1946. [Class 142 (ii)] A clamping device 16 seizes a weft thread, positions it, and causes a reduced clamping force to be applied to it to facilitate the formation of a selvage. When a weft thread 10 has been inserted into the shed 18, a cam 27 on a bell crank lever 25 is raised by a cam 23 on a shaft 22 and springs 29, 30 close clamping jaws 20, 21 before the thread is released from the shuttle. The clamping device is moved from position II to position I by a cam 45, roller 37 and a lever 36. A cam 46 presses down a needle 33 to reduce the spring clamping force and permit the doubling round of the end of the weft thread to form the selvage. The clamping force may be reduced at one or at both sides of the shed. The cam faces 27, 46 may be replaced by two separate cams each on separate levers and controlled by separate cams..By suitable arrangement of the cams on the shaft 22 different tensions may be applied to any particular weft thread.
