IPC: C05F17/00
Filed: 1982-04-08
Abstract: The process is one of introducing solid, liquid and/or mud waste along with biodegradable organic refuse into the body of earthworms, adding air in order to supply the latter with oxygen, and water for the purpose of counteracting heat produced by fermentation, extracting fumes and making provision for stirring the central body of the mass of worms and waste. The contrivance consists of one or more silos (1 or 39) ten metres or more in height set singly or disposed in batteries and with a tapered lower region; each silo furnished with tubes (29) having radially-set holes (30) for passage of water and air, as well as an axial agitator screw (25) likewise with holes (26) for passage of mud, air and cooling water; there being perforated side-wall sectors (7 & 8) with corresponding inlet and outlet chambers (9) allowing expulsion of fumes; ultimate extraction of the end-product fertilizer brought about by alternating draw-off trays (16) passing back and forth across the silo lower orifice.

Abstract: A signal is produced which is representative of a position of a part of a mould (1b, 7b, 8b, 9b) at a time in a cyclic process of forming glassware when the mould (1, 7, 8, 9) should be closed. This signal is compared with a signal representative of the position of the mould part (1b, 7b. 8b. 9b) when the mould is correctly closed. This latter signal is produced by averaging a selected number of the immediately preceding signals representative of the position of the part of the mould at the time when the mould should be closed.

Abstract: A glass optical waveguide preform is formed by chemical reaction of gaseous and/or vapourised ingredients (A and B) within a glass substrate tube (52). A reactant feed tube (50) extends Into a first end of the substrate tube (52). One of the reactants (A) flows through the feed tube (50), and another (B) flows through the annular channel between the feed (50) and substrate (52) tubes. The reactants (A and B) combine just downstream of the end of the feed tube (54) and react to form particulate material, of which at least a portion is deposited on the substrate tube (52). The output end of the feed tube (50) traverses (58, 60) the substrate tube (52) so that the region of maximum soot deposition moves along the length of the substrate tube. A hot zone (54, 56) traverses (18a', 18b') the substrate tube (52) in synchrony (58) with the feed tube (50) to sinter the deposited soot.

Abstract: A sealed package for pressurizing the contents of dispensing containers. The package contains chemicals which react to develop gas pressure to expand the package when in the dispensing container.

Abstract: 1. Method for controlling the magnetic flux of an asynchronous machine which is fed from an inverter with a multi-phase voltage of adjustable frequency and amplitude, and in which the control commands for the inverter are derived from signals representing the stator voltage and the stator frequency, in which arrangement the stator frequency is determined by summing the slip frequency and determined frequency of rotation of the asynchronous machine, characterised in that for achieving a proportional dependence of the magnetic flux in the asynchronous machine on the direct voltage (Ud ) present at the input of the inverter, this direct voltage is used after multiplicative combination with the intermediate circuit current (Id ) and after processing in an output regulator (24), for correcting the command variable, which is in each case supplied, together with the frequency of rotation (fn ) of the asynchrones machine, to two characteristic-curvegenerators (27, 28) for forming the slip frequency (f2 ) and nominal stator current value (I1-* ).

Abstract: A high torque transfer electromagnetic clutch having a rotor (15) which is rotated by an external driving power source through a belt, an armature plate (8) attached to a drive shaft (3) and an electromagnetic means (101) for selectively attracting the armature plate (8) into engagement with the rotor (5) for transmitting the rotation of the driving power source to the drive shaft (3) via respective frictional surfaces (5a, 8a). In one embodiment of the invention, one frictional surface is machined to a rough surface with a pluralityof uniformly formed peaks, each peak having an acute shape. The surface is then covered with a film layer of plating. The other frictional surface is finished by polishing. When the frictional surfaces engage, particles from the film layer are shaved off and accumulated in minute depression in the other frictional surface. Particles are also shaved from the other frictional surface and adhere to the film layer particles to form a material which exhibits a high resistance to the shear forces created by the rotating rotor. Accordingly, the level of torque transferred by the clutch is increased. 
     In other embodiments of this invention, the peaks of the machined frictional surface are trapezoidal in shape, thus providing more contact surface upon engagement of the frictional surfaces and thereby increasing the amount of torque transferred. In a further embodiment of the invention, the film layer is formed from a powder material.
