Filed: 1968-01-15
Abstract: 1,194,141. Detecting neutrons. TOKYO SHIBAURA ELECTRIC CO. 15 Jan., 1968 [17 Jan., 1967; 18 Nov., 1967], No. 2176/68. Heading G6P. In a bitreous material used to measure a neutron flux, fission products cause changes in the surrounding material which are disclosed by an etching process. The number of etch pits is directly proportional to the number of incident neutrons. The material is formed of a mixture of a firrile substance, alkali metal metaphosphates and metal metaphosphates, which is melted, formed into thin plates and cooled. A neutron permeable coating of lead or zinc may be provided to shield the user against the reactions produced by the spontaneous fission of the fissile ingredients. Alternation of the spontaneous fission radiation is also effected by the bitreous metaphosphate components. Two or more kinds of fissile substances may be included so as to provide adequate sensitivity over a broad spectrum of neutron energies, such as an oxide of thorium uranium, plutonium or neptunium.

Title: Improvements in and relating to the production of ammonium cyanide
IPC: C01C3/00
Filed: 1934-05-10
Abstract: Ammonium cyanide is obtained by heating an intimate mixture of thiourea and/or ammonium thiocyanate with a metal which will combine with sulphur, the mixture being heated rapidly to about 300 DEG  C., and thereafter less rapidly to about 500 DEG  C.  The ammonium cyanide may be recovered from the resulting gases by a dry method or by absorption in water.  Suitable metals are copper, iron or zinc. The addition of substances such as paraffin to the mixture facilitates the reaction.  The rapid heating to 300 DEG  C. may be effected by introducing the mixture, a little at a time, into a muffle or similar furnace heated to about 300 DEG  C. Cuprous sulphide resulting from the reaction can be reconverted into the metal in the same apparatus by oxidation to copper oxide followed by reduction to copper, say by means of coke oven gas or by heating with excess of paraffin.  Specification 438,358 is referred to.ALSO:Copper sulphide, obtained together with ammonium cyanide by heating thiourea or ammonium cyanate or both with copper, is reconverted into the metal in the same apparatus by oxidation to the oxide followed by reduction to the metal, say by means of coke oven gas or by heating with excess of paraffin.

Abstract: 255,341. Kreissig, E. Jan. 28, 1926. Springs, arrangement of.-A spring suspension for vehicles comprises two oppositely-arranged spring-systems connected by a lost-motion mechanism, each system including two inclined pivoted members 26, 27 and 39, 40, and an elastic or partly elastic transverse member connecting them, and the system loaded initially is so arranged that its resistance to deformation decreases as deformation proceeds whilst the second spring system, which augments the first system after a .predetermined deformation, is so arranged that its resistance to deformation increases as deformation proceeds. The first system comprises two opposed rods 17, 18 having enlarged heads 21, 22 adapted to compress springs 19, 20 housed in a casing 23, the ends of the rods being screw-threaded to take trunnion blocks 24, 25, to which and the axle box 43 are attached the links 26, 27 respectively. The second spring-system comprises the links 39, 40 each connected at one end to the axle-box 43, the opposite ends being connected to sliding trunnion blocks spaced by a spring 42 on a shaft 41. The two systems are connected by a lost-motion system comprising links 35, rod 37, and guide 38, the lost motion x being determined by the movement of trunnion blocks 33 on the shaft 17. The application of the load tends to cause the links 26 27 to move into alignment under the compression of the springs 19, 20 until the lost motion x is taken up, after which the spring 42 is compressed. The casing 32' is formed with teeth adapted to engage teeth on a rack carried by the axle-box so that movement of the axlebox up or down revolves the casing and automatically adjusts the distance apart of the trunnions 24, 25. and the distance x to suit the load carried. The system may be adjusted non- automatically.

[Also in Group XL (c)] A transistor circuit suitable for use in a motor control system comprises two variable potentiometers connected in parallel to form a bridge, a transistor having its input connected between the sliders so that the transistor current depends upon the position of the sliders, and amplifier transistors coupled to the output of the bridge transistor and connected in series with the bridge and its source of supply. Fig. 2 shows a bridge circuit comprising potentiometers 3 and 4 connected through a resistor 12 across a power supply 5, 6, the position of one or more of the sliders being varied by a control signal. The sliders form the output diagonal connections of the bridge and are connected to the emitter and base electrodes of two transistors 7<SP>1</SP>, 7<SP>11</SP> so that when a control signal causes the unbalance of the bridge to exceed a certain amount, one or other of the transistors conducts. These transistors have their collectors connected respectively to transistors 11<SP>1</SP> and 11<SP>11</SP> which are normally conducting. When transistor 7<SP>1</SP> or 711 conducts a point is reached when resistance of the collector base path of transistor 11<SP>1</SP> or 11<SP>11</SP> rapidly increases, causing transistors 15<SP>1</SP> or 15<SP>11</SP> to conduct, so rendering transistors 181 or 18<SP>11</SP> of opposite conductivity type also conducting. These transistors feed a bridge arrangement of transistors 24, 25, 26, 27, 34, 35, 36, and 37, having its output diagonal connected to a motor 23, so that current flows through the motor in a direction dependent upon whether transistors 18<SP>1</SP> or 18<SP>11</SP> are conducting and therefore in accordance with the direction of the unbalance of the bridge. Rectifiers 9<SP>1</SP>, 9<SP>11</SP> are provided to limit the input voltage to the transistors 71 and 7<SP>11</SP>. Specification 884,767 is referred to.

Title: N-substituted carbamyl chlorides and their preparation
IPC: C07C271/04
Filed: 1961-01-23
Abstract: The invention comprises N-substituted carbamyl chlorides having the formula <FORM:0980262/C2/1> or <FORM:0980262/C2/2> wherein R1 is alkyl or phenyl, R2 is hydrogen or alkyl, R3 is hydrogen, alkyl or phenyl, and R4 is alkylene.  The invention further comprises the preparation of these and other N-substituted carbamyl chlorides, wherein phosgene is reacted with an aliphatic or araliphatic acid amide containing one or more acylamino groups, in the stable or keto form of which only one hydrogen atom is bound to the nitrogen atom of the or each acylamino group present and at least one hydrogen atom is bound to the carbon atom next to the carbon atom of the or each acylamino group present, the said acid amide being used (a) as such and while ensuring that at all or substantially at all times during the reaction there is an excess of the phosgene over the stoichiometric amount (i.e., more than 2 molar proportions of phosgene per said acylamino group), or (b) in the form of the hydrochloric acid salt.  When the acid amide is used as such, the necessary excess of phosgene is ensured by slowly adding the acid amide to the total required quantity of phosgene.  When the acid amide is used in the form of the hydrogen chloride salt, the phosgene may be added to the salt.  Solvents such as hydrocarbons and halogenated hydrocarbons may be used in the reaction. The reaction may be carried out at atmospheric or superatmospheric pressure, preferably between 10 and 25 atmospheres. Preferably, the reaction is initiated at a temperature between -5 DEG  and +45 DEG  C., and after a short period the temperature is raised to between 45 DEG  and 120 DEG  C.  The examples illustrate the preparation of N-n-propyl-N-(1-chloro-1-propenyl) - carbamyl chloride, N - n - propyl - N - (1 - chloro - 1 - octadecenyl) - carbamyl chloride, N - n - propyl - N - (1 - chloro - 1 - isobutenyl) - carbamyl chloride, N - phenyl - N - (1 - chloro - 1 - propenyl) - carbamyl chloride, N - methyl - N - (1 - chloro - phenyl - ethenyl) - carbamyl chloride and N,N1 - bis - (1 - chloroethenyl) - hexamethylene - 1,6 - dicarbamyl chloride.
