Title: Preparation of organo bis (aminoboryl) compounds and bis (hydroxyboryl) compounds
IPC: C07F5/02
Filed: 1961-01-03
Abstract: 1,2-bis[bis(alkylamino)boryl] compounds of the formula <FORM:0900135/IV (b)/1> are made by reacting in the presence of a boron trihalide a tetra(alkylamino)boron compound having the general formula: B2(NRR1)4 with an olefine having the general formula R2.CH=CH.R3 wherein R represents an alkyl group having 1 to 4 carbon atoms, R1 represents hydrogen or an alkyl group having 1 to 4 carbon atoms, and R2 and R3 are the same or different and each represents hydrogen or an alkyl group having 1 to 4 carbon atoms or R2 and R3 together represent an alkylene group having 3 to 6 carbon atoms, which alkylene group is unsubstituted or substituted with phenyl groups or with alkyl groups having 1 to 4 carbon atoms.  The reaction preferably takes place below 25 DEG C.  Suitable olefines are ethylene, cyclohexene, cyclopentene, cycloheptene, cyclo-octene or a methyl or phenyl substituted cyclohexene, and tetra (dimethylamino) diboron, tetra (diethylamino) diboron and tetra (isopropylamino) diboron are other specified reactants.  The tetra(alkylamino) compounds can be hydrolysed by conventional methods to yield the corresponding 1,2-bis(dihydroxyboryl) compounds, but it is preferred to first prepare the 1,2-bis (alkoxyboryl) compound, e.g. by treating the alkylamino compound with absolute methyl alcohol, and then hydrolysing the alkoxy compound, e.g. with water.  In Examples, (1) tetra (dimethylamino)diboron reacts with cyclohexene in a nitrogen atmosphere in the presence of boron trichloride and the resulting 1,2-bis[bis (dimethylamino)boryl] cyclohexane is treated with absolute methanol forming the methoxy compound which is hydrolysed with water and yields a novel compound, 1,2-bis(dihydroxyboryl)cyclohexane; this gives cis-1,2-dihydroxy cyclohexane when oxidised with hydrogen peroxide; (2) ethylene is bubbled into tetra(dimethylamino)diboron and boron trichloride in petroleum ether under nitrogen, the product is treated with absolute methanol and hydrolysed to yield 1,2-bis(dihydroxyboryl)ethane.

Title: Method of producing colour-photographic printing-out images
IPC: G03C1/73
Filed: 1933-01-04
Abstract: 417,588. Colour photography. GASPAR, B., 38, Innsbruckerstrasse, Schoneberg, Berlin. Jan. 4, 1933, No. 289. Convention date, Jan. 4, 1932. [Class 98 (ii).] Multi-colour photographic pictures are obtained by copying from coloured images, or black-and-white images with the use of colour filters, on to light-sensitive material consisting of intensely-coloured, light-sensitive, dyestuff forming substances or preliminary stages of dyestuffs, either in superimposed layers or in admixture with each other. The coloured substances may be combined with colourless light-sensitive substances or with print-out metal salts. Diazo and leuco bodies are particularly suitable. The diazo bodies may be in the form of diazoamino compounds or diazo anhydrides ; they may be combined with coupling components or these may be applied in a developer. Diazo compounds of the diazotisation dyestuffs are specially referred to. In an example, a three-colour picture is formed in a light-sensitive material consisting of the blue diazotized compound of Diamine Pure Blue, red diazo amino-acridine or other red diazo compound, and diazotized Diazo Light Yellow. The material in the form of a single layer or superimposed layers, is exposed below a coloured master image, developed with #-naphthol or #-oxynaphthoic anilide and washed. Reversed images may be obtained by using diazo sulphonates. The coupling compound may be incorporated in the material. The material may contain the amino compound with coupling components and a nitrite, and diazotisation be performed immediately prior to copying. Other suitable light-sensitive substances referred to are nitroso compounds, triazines, nitrosamines &c. Suitable leuco bodies are the leuco-esters, ester salts and ethers of the vat dyestuffs, or the intermediates or preliminaries of the indigo or thioindigo series, e.g. the leuco ester or ethyl ether of hydroflavanthrene, indoxyl carbonate, dehydroindigo &c. A two-colour example comprises the sodium salt of the sulphuric ester of hydroflavanthrene admixed with indoxyl sulphate of potassium which gives a yellowblue negative image from a blue-red master image ; the unchanged compound is removed by an alkaline bath or by solvents. When print-out metal salts, e.g. of iron or silver, are employed, the resulting image may be converted into an image of the desired colour by suitable toning or colouring processes, e.g. as described in Specification 397,159. Coloured dyestuff forming substances of different groups may be combined, e.g. coloured diazo-sulphonates, with coloured leuco-esters. Filter dyestuffs, preferably such as are readily removable, e.g. by washing or bleaching, may be added. To permit of subsequent colour correction, the resulting dye images should be made up of dyestuffs having varying powers of resistance to the action of solvents or bleaching &c. agents. Specification 390,616 also is referred to.

Title: System for the transmission of data elements by linear frequency modulation
IPC: H04L27/14
Filed: 1973-01-04
Abstract: 1416261 Data transmission systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 4 Jan 1973 [7 Jan 1972] 562/73 Heading H4P In a data transmission system where binary data is transmitted as a frequency sweep through a centre frequency which is positive going or negative going according to the binary value to be transmitted, the transmitter includes a circuit for maintaining constant the centre frequency and slope of the sweeps, and the receiver includes a synchronizing circuit which has a narrow band pass filter to detect the passage of a sweep through the centre frequency in order to synchronize the phase of a local clock to the received data. In the transmitter shown in Fig. 3 binary data at input 33 operates transistors 44 and 45 according to the binary value to supply to oscillator 35 either a positive going or a negative going control voltage supplied from sawtooth oscillator 37 and true and inverting amplifiers 42, 43. Oscillator 35 thereby supplies positive or negative going frequency sweeps through a central frequency f0 for transmission. Counter 49 counts zero crossings of the output frequency for a predetermined number of data elements, as determined by a signal 51 from quartz controlled master clock 32, and the final count, if different from a predetermined value, supplies via decoding circuits (not shown) and LP filter 50 a signal 48 to correct the frequency of the oscillator. A further counter 53 also counts zero crossings, but positively during one half cycle of a data element and negatively during the other. The count accumulated after one or a predetermined number of data elements is used via decoding circuits (not shown) and LP filter 54 to control via transistor 56 the supply of charging current to capacitor 38 in the sawtooth generator 37. The master clock discharges the capacitor via transistor 41 at the end of a sweep corresponding to a period of a data element. In the receiver (Fig. 1) the received data signal, which in the embodiment is frequency transposed in mixer 5, is fed to a very narrow band pass filter 40 tuned to the transposed centre frequency to give a burst of A.C. centred on the mid-point of each data element, which bursts are converted to pulses by detector and regenerator circuits 6, 7. For each pulse, generator 13 supplies a predetermined number of pulses to counter 11 which is caused to alternately count up and down during alternate periods of the local clock signal supplied over lead 12 from a master clock driven divider 9. A deviation of the local clock signal from the mid-point of the data elements causes a count to accumulate which, via decoding circuits not shown, controls the divider 9 to adjust the phase of a local clock signal.

Title: Silicon carbide resistance body and method of making the same
IPC: H05B3/14
Filed: 1961-01-06
Abstract: The content of free silicon and carbon in a silicon carbide body containing Beta SiC, prepared by siliconizing a carbon-containing body, is decreased by maintaining the body at 1800 DEG -2300 DEG C. under time-temperature conditions such that the silicon carbide remains in the beta form.  This annealing will decrease the free silicon content from more than 20% to not more than 10% and the free carbon content from more than 15% to not more than 5% by combination as silicon carbide.  In joining together pieces of silicon carbide, or silicon carbide and a preformed carbonaceous body, the components are joined with a resin, or an adhesive containing flour, charcoal, carbon and casein glue.  After drying, which may take 8-10 hrs. at room temperature, or less at a high temperature, the joint and preformed carbon body, if present, are siliconized by heating to 1800 DEG C. in the presence of powdered silicon.  The siliconized parts are then annealed for 30 mins., preferably in an inert atmosphere. The silicon carbide body, in a graphite boat, or crucible, is passed through a graphite tube furnace at a uniform rate and thence through a water-cooled tube.  The siliconizing and annealing can be achieved in one stage if powdered silicon is introduced into the crucible, with the jointed body and the temperature gradient and through-put time of the graphite furnace are adjusted accordingly.  In the examples, the production and treatment of silicon carbide resistance heating elements having a hot section welded to cold ends is described.  Specifications 365,081, 396,088, 513,265, 513,728 and 583,039 are referred to.

Abstract: 363,162. Vapour burners. JUNKERS, H., 21, Kaiserplatz, Dessau, Anhalt, Germany. Jan. 9, 1931, No. 814. Convention date, Jan. 27, 1930. [Class 75 (i).] A liquid fuel burning apparatus comprises a vaporizing chamber of sufficient capacity to accommodate all the fuel needed for one heating operation and a vessel situated beyond the range of the heat from the burner and adapted to receive the fuel ejected from the vaporizer chamber when the burner is in operation. In the apparatus shown in Fig. 1 the vaporizing chamber 1 is filled at starting through a pipe 8 to the level F-F. The pipe 8 is then closed bv a stopper 9 and vaporization of the fuel in the chamber is initiated by burning, fuel in a bowl 4. The vapour passes through a pipe 3 to a nozzle 7 and is ignited, by the flame from the bowl 4. The heat produced causes an increase of the vapour pressure in the vaporizer and the fuel is driven through a pipe 6 to a vessel 2 so that its level in the vaporizing chamber falls to G-G. Fig. 2 shows another form of apparatus in which the pipe 3 is connected to an upwardly inclined pipe 16 crossing the flame passage of the vaporizer and forming an auxiliary vaporizer to facilitate starting. Fuel is supplied from a Marriotte bottle 10 to a vessel 11 to a level F-F and passes to the vaporizing chamber through a pipe 12 which is fitted with a check valve 13. The valve 13 is turned to the closed position when the burner is in operation. A valve 15 in a pipe 14 connecting the vessel 2 to the pipe 12 can be opened to allow the operation of the burner to be stopped at any time by the return of the fuel to the vessel 11. Fig. 3 shows another form of apparatus in which the fuel in a U-tube 18 connected to the vaporizing chamber is vaporized initially by a burner 5 which is charged by a pump 24 from a chamber 20 in which a constant fuel level is maintained by a float-operated valve 22. A three-way cock 26 allows the vaporizing chamber to be charged and also the return of fuel from the vessel 2. Fuel leaking past the cock 26 into its casing 27 returns to the chamber 20 through a pipe 28. The open end of the pipe 6 extends above the highest liquid level in the vessel 2 and is formed with gauzecovered openings 29 at the lower part of the vessel.
