Abstract: Organic material is heated in a pyrolytic reactor 15 in which an initial charge of charcoal is located, thereby driving off volatiles from the organic material while leaving charcoal (char) behind. The volatiles are then passed over a base material which is at a temperature substantially above the pyrolizing temperature which causes a chemical reaction of the tars and volatiles, resulting in an output of a gaseous mixture consisting largely of carbon monoxide and hydrogen, characterized by an absence of tars. The reactor 15 is arranged to permit a continuous flow of organic material volatiles, and char through it, resulting in continual replenishment of organic material in its pyrolizing portion, and replenishment of the charcoal bed portion by the char produced from the pyrolysis reaction.

Abstract: A vascular clamp for use in surgery has a body in the form of a tapering flexible envelope, with an inlet tube at the broader end. An external strip at the broader end provides a slot through which the tail of the envelope can be threaded after passing it around the vessel. The envelope is then inflated, e.g. by a syringe, to compress the vessel. A tap closes the inlet tube after inflation, and can be operated to partially deflate the envelope and so check for leaks of blood. The disclosure also includes a method of using the vascular clamp for occluding a blood vessel.

Abstract: Ductility is controlled by controlling the size of the particles of particulate material and/or the degree of sphericity of the particles, the smaller and/or more spherical the particles, the greater the ductility of the material. The material has preferably spherical pores, preferably hermetic, with a controlled ratio of pore volume to material volume to provide the property of compressibility. The particulate material itself must have the capability of becoming ductile. The ratio of pore volume to total volume of the material is controlled by particle size, sintering profile the property of the material and the initial volume loading of the pre-sintered part (i.e. the ratio of binder to particulate material). Some materials which are not ductile in and of themselves can be formed into ductile and/or compressible materials in accordance with the system of the present invention. This material can then be formed into a predetermined shape with subsequent binder removal and sintering in accordance with prior art methods except that the sintering profile may be controlled, if necessary, as one means of controlling the desire porosity of the part. 
     Materials as described above can be formed by inelastic compression techniques since the articles are compressible due to the voids, the compressed material retaining its compressed shape. This can be provided by the well known coining, hot isotatic pressing techniques and other well known techniques. Precision parts with densities approaching theoretical maximum density for the material involved can be preformed using these techniques. In accordance with this method, a part is formed and sintered having a shape which is substantially the same as the final shape desired but of slightly larger dimension. This article is then placed in a forming die cavity and compressed according to the contour of the die. Unlike conventional materials, the form will compress to the shape of the die with great accuracy. It is necessary, of course, that the degree of compression in the forming machine in volumetric terms be the same as or less than the volumetric content of the pores within the body to be formed. In this way precision parts can be formed to predetermined substantially exact dimension with substantially no flash.

Abstract: A nonlinear resistor comprising a sintered body (1) containing zinc oxide as a major component and at least bismuth oxide and boron oxide and electrodes (2,3) formed thereon, said sintered body having a higher y-form bismuth oxide phase concentration in upper and/or lower surface layers (11) of the sintered body than in the inner portion of the sintered body, has stabilized properties against long-time voltage application. When the sintered body is further modified by making the y-form bismuth oxide phase concentration in the periphery portions (121) of the upper and/or lower surface layers (11) lower than that in the inner portions of the upper and/or lower surface layers, the resulting nonlinear resistor shows a higher long-duration current impulse withstand capability.

Abstract: A typewriter of the hammer type has an ink ribbon (25) contained in a cartridge located to the side of the hammers. The depression of each typing key causes the cartridge to swivel so that its lateral appendix (29) raises the ribbon at the typing point (0). A second cartridge (26) containing a correct--ing ribbon (27) is normally kept away from thetyping position. The depression of a correcting key controls a correcting mechanism which locks the cartridge containing the ink ribbon, and swings the cartridge containing the correcting ribbon up and towards the centre so as to position the active part of the correcting ribbon above the typing point (0). When the key of the characterto be erased is then depressed to strike the hammer, the ink ribbon cartridge stays locked while the cyclic hammer actuating mechanism also hilts the correcting cartridge to lower the active part of the ribbon (27) to the typing point (0).

Abstract: The application relates to a circuit arrangement for logically combining alternating-voltage-shaped input signals to form an alternating-voltage-shaped output signal by rectifying the input signals to form a direct-current signal which controls an oscillating circuit with amplifier. The invention consists in the fact that at the inputs, capacitors (5, 6) having 4 diagonally opposite terminals are provided for effecting DC isolation, the inputs (E1, E2) being connected to one plate and rectifier circuits of oppositely polarised diodes (7, 8, 9, 10) being connected to another plate, which diodes are connected to smoothing circuits of capacitors (11, 12) having 4 diagonally opposite terminals and Zener diodes (15, 16) for stabilisation, which are connected to an oscillator circuit (17) preceding the output. One input in each case is serially looped to another logical combination circuit. The doping is selected in such a manner that the battery voltage used for generating the alternating-voltage input signals in each case has the opposite polarity to the operating voltages needed by the oscillator circuit and generated by the input capacitors and rectifier circuits in dependence on the alternating-voltage signals. <IMAGE>
