Title: Extraction of endocytines
IPC: A61K35/14
Filed: 1953-06-08
Abstract: Endocytines are extracted from organic liquids, tissues or organs except hormone-secreting glands, by electrophoresis or electroosmosis, preferably without interruption at a potential difference of 200 to 250 volts between platinum electrodes, in distilled or deionized water.  The organic liquid, e.g. amniotic fluid or blood may be contained in a calf's bladder insulated from the platinum needle or electrode, for example, by a glass tube. The solid tissue, e.g. living foetus, foetus tissue such as brain, liver, heart, lungs, kidneys, intestines, stomach, thumys, thyroid gangliones of higher mammals such as sheep, goat, guinea pig, rabbit, oxen, is removed immediately after the death of the animal and may be utilized immediately or may be kept at 2 DEG  C. for up to eight days prior to use.  The extracts may be preserved against microbiological decomposition by addition of one volume of 96 per cent ethyl alcohol to four volumes of the aqueous extract.

Title: Improvements in superheterodyne radio receivers with pre-set tuning
IPC: H03J5/32
Filed: 1939-05-26
Abstract: 520,819. Wireless receiving apparatus. PHILIPS LAMPS, Ltd. May 26, 1939. No. 15780. Convention date, May 30, 1938, [Class 40 (v)] The adjustment of the pre-set reactances in a push-button tuned superheterodyne radio receiver is facilitated by the provision of switching whereby each reactance may in turn be inserted in the local oscillator circuit and adjusted to a determined value. With button 10 depressed and switch arms 11, 12, 13 in engagement with contacts 15, 17, 19, the input circuit 3 and oscillator circuit of the mixer-valve 2 are tuned by means of the condensers 6, 7, 8. If button 10 is released and button 30 depressed, the circuits are tuned by the pre-set capacities 37, 38, 39. To adjust these pre-set capacities the button 10 is depressed and the desired station tuned in on the condensers 6, 7, 8 which have equal capacities, the switch 20 is changed over, and the switch 49 closed. This replaces condenser 8 by condenser 39 which is then adjusted to bring the receiver into tune: Switch 49 is opened and switch 48 closed while condenser 38 is adjusted, and similarly for condenser 37. The three pre-set condensers 37, 38, 39 are then adjusted to the same value and other groups of condensers such as 57, 58, 59 can be adjusted in the same manner for different stations. In a modification, Fig. 2 (not shown), the switch 20 on changing-over makes contact with all three switch arms 31, 32, 33, which are capable of being depressed individually to place the pre-set condensers in the oscillator circuit.

Abstract: 810,294. Casting-machines; making aircraft; brazing. BRENNAN, J. B. June 2, 1955, No. 15822/55. Classes 83 (1), 83 (2) and 83 (4). A mould is moved with respect to a moltenmetal supply source and is charged at successively higher levels of the mould cavity, each charge flowing upwardly in that cavity. A permanent, two-part mould 4, Figs. 1 and 2, defining a cavity 8 for an air-foil section, has gates 12 at different levels, and risers 11. The mould is surrounded by a crucible 15 which has valve-plates 16, movable by handles 19, for opening and closing discharge-ports 17, and which plates may be pressed against the mould to form a fluid-tight seal by hydraulic cylinders 18. A heating-coil 14 surrounds the crucible, and a cooling-device 20 is secured to the bottom of the crucible. In operation, a mould on the base-plate 2 is preheated by the coil 14, the plates 16 are raised to allow molten metal to enter the mould through the lowermost gates 12, and the crucible is then progressively raised to cause the metal to flow through the other gates 12 in succession. The cooling-device 20 being raised with the crucible, the solidification of the metal in the mould progresses from the bottom upwardly. Alternatively the crucible or cooling-device may be stationary, and the mould moved. In a modification, Figs. 4, 4a, the molten metal is contained in the hollow walls of a structure having a stepped base 30a. The mould 4 has gates 12 at different levels which correspond with gates 16 in said hollow walls, so that metal flows through the gates 12 in succession as the mould is moved from one step to the next. Stepped cooling walls 31 cause a progressive cooling of the mould. Alternatively the crucible and cooling-walls may be moved past a static-mould. Making aircraft; brazing.-Two cast portions 35, 36, Fig. 5, of an airfoil section, e.g. of aluminium alloy, are joined by placing aluminium brazing compound between the abutting machined faces, and heating in a brazing furnace or by high-frequency heating. Alternatively, the portions with the brazing compound between are squeezed together in a close-fitting die heated to approximately 400-500‹ F.

Filed: 1974-04-11
Abstract: 1473383 Controlling light RANK ORGANISATION Ltd 9 April 1975 [11 April 1974] 16085/74 Heading G2F In an electro-optic cell exhibiting variable optical rotatory power and comprising a layer of liquid crystal material with positive dielectric arisotropy between parallel walls, the liquid crystal material is mainly nematic but contains at least some cholesteric component in order to provide a twisted molecular structure with a uniform sense of twist throughout in the absence of an electric field, and the molecules adjacent each wall are uniformly inclined thereto but at a different angle for each wall such that no place intermediate and parallel to the walls consists of molecules aligned parallel to the walls, whereby when a field is applied across the thickness of the layer all the liquid crystal molecules are rotated in the same sense to the parallel with the field. The formation of domains with opposite twist in the absence of a field, and of domains of anti-parallel molecules with different birefringence in the presence of a field which leads to inhomogeneity colour fringes in a display when the cell is between polarizers, is thereby avoided. As described, the molecules are caused to lie at 20-30 degrees to one wall and substantially parallel to the other wall by vapour deposition on the wall surfaces at 5 and 30 degrees respectively. The cholesteric component may be cholesteryl nonanoate, 0À25 wt. per cent based on the nematic component.

Title: Fibre-forming polyamides
IPC: C08G69/30
Filed: 1965-04-21
Abstract: The invention comprises a process for the production of fibre-forming linear polyamide by polymerization of a diamine-dicarboxylic acid salt with the polymerizing material maintained in finely divided solid form throughout the polymerization, wherein the salt is heated with agitation for an initial period together with at least 2% and less than 100% of its weight of an inert organic diluent under superatmospheric pressure generated or supplemented by water vapour, formed in the polymerization and diluent vapour, liquid diluent being present throughout this period and the pressure is thereafter reduced by release of vapours from the polymerization vessel while continuing heating and agitation, the temperature throughout the process at all times being below the m.p. of the polymerizing material and not more than 60 DEG  C. below the m.p. of the salt.  Polyamides specified include nylon 66.  The inert diluent may be a solid at room temperature but a liquid at the reaction temperature or may have a m.p. below 30 DEG  C.  It may be a nonsolvent and may have a b.p. of 100-300 DEG  C. Liquids specified include diphenyl ether, bis (2-ethoxyethyl) ether, xylene, a diphenyl ether/ diphenyl mixture, a salt of a deodorized kerosene fraction and a chlorinated diphenyl. 2-25% may be used.  1-100% of water may be present and in this case the mixture should be heated at autogenous pressure and then water allowed to escape until 0.1-25% remains. Heating to polymerize may begin at atmospheric pressure or up to 100 p.s.i.g. of an inert gas, e.g. N2 or argon, and continue at autogenous pressure in a sealed vessel.  The temperature may be 240-325 DEG  C. and the maximum pressure 300-1200 p.s.i.g.  The reactants should be agitated by stirring or vibrating, rocking or rotating the reaction vessel and the surface temperature of the vessel should be uniform to within 50 DEG  C.  The reaction may be completed by allowing the pressure to drop to 0-100 p.s.i.g. and changing the temperature to 250-325 DEG C.  The product may be made into a shaped article.
