Title: Infiltrated hard refractory metal
IPC: C22C1/05
Filed: 1963-03-27
Abstract: A sintered refractory hard metal is formed by infiltrating a molten hinder metal with a melting point of 1500 DEG -3000 DEG F. into the interstices between spheroidal powder granules of hard metal which have been formed from molten drops of the hard metal.  The hard metals are the carbides, borides, nitrides and silicides of the metals of the fourth to sixth group of the Periodic Table e.g. Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W and small amounts of Fe, Co or Ni may be present.  The spheroidal particles minus 20 plus 400 mesh Tyler are formed either by arc melting a consumable hard metal rod, or feeding a hard metal rod into the plasma generated by the arc or by entraining hard metal powder in a gas stream which is fed to the arc. The preferred hinder infiltrant contains 50% or more of Fe, Co or Ni and may also contain Cu, Sn, Mn, Cr, Al, Mo, Be, Bi, B, Cd, C, Si, Ag, Ti, W, Zr, Nb, Ta, Zn and hard metal carbides.  A large number of different hinder alloy compositions are specified. Prior to infiltration the hard metal spheroids are loosely packed, vibrated or lightly compacted at 100-200 p.s.i. in a carbon or ceramic mould, preheated to 300 DEG -600 DEG F. and the molten hinder is then poured into the mould. Rapid cooling with air or water is preferred after infiltration. Diamonds or normal particles ( 1/32 "-\ba1/2 ") of carbides, or borides e.g. WC and TiB2 may be added to the hard metal spheroids prior to infiltration and by packing the spheroids on a steel blank placed in a mould a coating of infiltrated hard metal is formed.

Patent GB-809505-A (GB)
Title: Improvements in or relating to growth regulating compounds
IPC: A61K35/26
Filed: 1955-04-27
Abstract: One or more organs of a living organism, preferably a warm-blooded animal, are artificially stimulated by irradiation, by chemical and like stimulants, by substantially reducing oxygen absorption by a tourniquet, or by subjection to low temperature and, from the organs so treated, or from body fluids circulating therethrough, substantially protein-free growth-regulating preparations are extracted by known chemical methods including a protein removal step. The growth-regulating preparations comprise nucleic acid derivatives, amino acids and polypeptides, and may be used in the treatment of degenerative diseases, such as thyroid diseases, leukaemia, nephrosis and X-ray ulcers.  The stimulation induces in the parenchema or mesenchema of the organ a state of unnatural activity which, it is stated, is to be regarded as a state of at least temporary mutation. In a modification, tissue from a stimulated organ is subjected to tissue cultivation. The stimulation may be intense irradiation as from radium, or by X-ray, ultra-violet, infra-red and heat radiation, electron and other elementary particle bombardment, or ultrasonic waves.  It may be by the incorporation of chemical stimulants which, as exemplified include fluorescent dyes, various drugs, inorganic materials, vaccines, sera, protein decomposition products and disinfectants.  Radio-active materials may be employed alone or with other of the chemical stimulants.  Examples include (1) the kidneys of a cow are irradiated by deep X-ray and blood circulating in the renal veins is removed to be worked up, (3) a dyestuff is injected into a pig which is then irradiated by ultra-violet.  The urine and skin are worked up; (4) indian ink is injected into a cow daily for about 14 days, the blood, the spleen and the thymus being worked up; (7) the blood circulation in a dog's leg is interrupted by tourniquet, the blood being later removed and worked up; (8) cultivated hen-egg heart tissue is irradiated by light and the nutrient solution worked up.

Title: Electronic error detection and message routing system for a digital communication system
IPC: H04L12/40
Filed: 1966-03-21
Abstract: 1,116,854. Electric selective signaling. GENERAL ELECTRIC CO. 21 March, 1966 [5 May, 1965], No. 12284/66. Heading G4H. [Also in Division H4] In a system comprising a master station and a plurality of slave stations, all on a common channel, messages transmitted from the master to a slave or vice versa are accompanied by a multi-element check signal, the message and check signal being such that, in the absence of errors, all slaves accept each message from the master, future action at the slaves depending on the message, and any message transmitted by a slave is accepted only by the master. As described each message from the master comprises two address words and one command word. The message is passed via stores to the transmission channel and also to a circuit, comprising a shift register with modulo-2 feed-back, which develops a check word which is transmitted with the message. At each slave the three message words are stored while checks are made on the message and check words. These four words pass to a check circuit similar to that which developed the check word at the master. If no error has occurred during transmission, the check circuit develops an output, or remainder, 0000 in response to the four words. The four words are also checked to ensure that no transition occurs during the second and third quarters of each bit. If the two checks indicate no error the three stored message words pass to a utilization device (not described), the operation of which depends on the message content. The slave transmitters are substantially identical to the master but are such that the message and check words provide a different remainder, e.g. 1000, at the master's check circuit if no error has occurred. Since this remainder is unique to the master no slave will respond to another slave's transmission.

Title: Jet propulsion
IPC: F02K7/08
Filed: 1946-04-24
Abstract: 832,339. Jet-propulsion plant. AEROJET GENERAL CORPORATION. April 24, 1946 [April 28, 1945], No. 12427/46. Class 110 (3). [Also in Groups XII and XXIX] In a jet-propulsion duct in which air, entering at 7, passes through valves 36, is periodically ignited with fuel in a combustion chamber 38 and is discharged through a propulsion jet 12, an auxiliary charge is exploded in the chamber and the main charge is thereby further compressed before being ignited. The auxiliary charge of an easily ignited fuel is admitted to a central tube 20, Fig. 1, through a pipe 26 and is ignited at 24. The main charge is introduced through nozzles 43 into a larger tube 40 and is first compressed and then ignited by the burning of the auxiliary charge. The tube 20 may be omitted and the auxiliary charge admitted at the down-stream end of the tube 40. The two charges in the tube 40 may be separated by a partition with nozzle-like perforations or, the auxiliary charge may be admitted to both ends of the tube 40 and the main charge admitted to the central portion of the tube. In another form, catalyst material 62, Fig. 10, is located at the end of the tube 40 and a substance catalytically decomposable in air is admitted through nozzles 60a. Alternatively, substances which ignite spontaneously in air may be introduced through nozzles 60a. If the main charge is petrol, the auxiliary charge may be oxygen and hydrogen, propane, butane, pentane, or other light hydrocarbon. When a catalyst is used, the auxiliary charge may be nitro-methane or nitro-paraffin and the catalyst, platinum sheet, or, manganese dioxide. The spontaneously igniting substances may be aluminium borohydrides, boron hydrides, trimethylborine, aluminium trimethyl or zinc diethyl. In the tube shown in Fig. 1, the combustion chamber is square at the upstream end changing to a circular section to conform to a circular jet pipe 8. The pipes leading to the nozzles 43 and the leads to sparking plugs pass through diagonal supports. The combustion tube 40 is spaced from the valves 36 in Fig. 1 and lies up against the valves in Fig. 10. The valves comprise a rectangular assembly of channelled plates 71, Fig. 7, interleaved with flexible valve plates 72. The channels have curved floors so that when the plates 72 lie against the down-stream edges 83 the flow of air through the channels is stopped. When the combustion tube 40, Fig. 10, lies up against the valve assembly, the valve plates are deeply slit to permit the two parts of the plates radially beyond the tube and the part covered by the tube to vibrate independently. Specification 805,329 is referred to.
