Abstract: AUTOMATIC FUNCTION MECHANISM FOR TYPEWRITERS A method and mechanism for automatically performing typewriter functions such as backspacing and disabling the escapement mechanism of a typewriter.  A ribbon cartridge carrying actuating abutments is inserted into the typewriter whereupon the abutments engage a mechanism to actuate a selected function as for example the backspace mechanism  and also engage another mechanism to disable the escapement mechanism.  Particularly adaptable to correcting typing errors, the present invention will minimize the manipulations now necessary to perform an error correcting operation.  Having typed an erroneous character, the operator simply inserts a ribbon cartridge containing the actuating abutments.  One of the abutments contacts an actuating mechanism within the typewriter to backspace the carriage.  The second abutment contacts a second actuating mechanism within the typewriter to disable the escapement mechanism to prevent carriage movement during error correction or until the ribbon cartridge is removed.  Other selected typewriter functions can also be actuated by cartridge insertion.

Abstract: A device for heating and mixing foods, such as a cooking mixer, includes a bowl in which a mixing blade is mounted for orbiting to commingle the food which constitutes the contents of the bowl in operation. A heater is also provided, which heats the contents of the bowl, and the orbiting blade improves the penetration of the heat energy throughout the contents by stirring the same. The device futher includes a separate subdividing accessory in the form of a cup-shaped insert which is permeable to the liquid component of the contents but impermeable to coarse solid components thereof so that when it is desired to comminute such coarse components by the action of the mixing blade, the device is operated without the insert, while the optionally inserted cup-shaped insert is said to contain such coarse solid particles and to prevent them from reaching and being comminuted by the orbiting mixing blade. The insert is supported on inwardly oriented ribs of the bowl, and a lid of the bowl contacts the insert and maintains the same in abutment with the ribs. A handgrip separate from the insert is used for introducing the latter into, and withdrawing the same from, the bowl.

Abstract: An arrangement for controlling a stream of fluidized solid particles flowing through a duct 14 to a discharge opening 15. The duct 14 prevents solid particles from reaching the discharge opening 15 simply by sliding in a non-fluidized state therethrough, due to the dimensions of the duct. Means are provided for controllably supplying a fluidizing gas to the duct to cause a fluidization of solid particles within the duct and this permits a controllable outflow of fluidized particles through the discharge opening. Said gas supplying means include a plurality of gas admission openings 19 in the wall of the duct and valve means 25 for individually controlling the supply of gas through each such opening. At least one additional separately controlled gas admission opening may be provided in the wall of a particle containing receptacle 12 at the input end of the duct at a level slightly above the outlet 13 of the receptacle. The apparatus shown may be used for gassifying coal. <IMAGE>

Abstract: Body 1 is heated by the combustion of gas at ring burner 14, which also preheats the incoming air. Cooled body 2 encloses the cold chamber. Displacer 4, which also operates as a heat exchanger is made of light weight construction and includes a magnetisable tube 8 so that it can be raised by electromagnet 6. Displacer 4 has a central bore 11 and heat insulating plates 10 so that it is hot at the top and cold at the bottom. With the working piston 3 in the T.D.C. position, magnet 6 is de- energised and displacer 4 is released, driving the working fluid into the hot chamber where it expands and forces down the piston and displacer. The piston 3 is returned by a buffer or the inertia of a crank system. The working piston may be coupled directly to linearly oscillating parts of a driven machine e.g. a compressor so that these parts will be substantially free of transverse forces. Where a crank drive is employed, control of the magnetic field moving the displacer may be by way of switches which are actuated by the drive, for example by cams on the crankshaft. <IMAGE>

Abstract: Despite varying designs, traditional collapsible washing- up stands are produced in accordance with one and the same construction principle: two plane gratings possessing parallel supporting bars (10 and 11) are connected to a through axle bar 12 around which the gratings can be rotated relative to each other. The washing-up stand according to the invention is produced in accordance with a novel, entirely different construction principle which rules out the use of a through axle bar. Two plane gratings have already been interleaved while they were being made, i.e. the supporting bars (22) on one of the gratings pass straight through the voids between the supporting bars 27 on the other grating. In addition to this, one of the gratings has been displaced sideways such that its supporting bars lie up against corresponding supporting bars on the other grating, with joint compartments for plates being formed between the pairs of supporting bars. By means of using a suitable suspension device 43 and 44 together with two bearings 30 and 31 at the outermost intersecting supporting bars, the opened-out washing-up stand assumes an expedient position. The simplicity of the construction is illustrated by: the fact that the deep plate position which is jointly shared by the two gratings is located sufficiently far from the rear wall without any special supporting device or space-demanding shaping, by the fact that one of the gratings of the washing-up stand offers a horizontal surface for placing relatively small washing-up dishes, the fact that, in its collapsed state, the washing-up stand requires so little space in depth that it can easily be folded into the bottom of a kitchen cupboard. <IMAGE>

Abstract: A control circuit for controlling either the position and the speed of travel of a press table or the hydraulic pressure acting on the press table, or both, in a hydraulic press, in particular a press for wood-based boards, comprising an actual-value transmitter for the position of the press table, a pressure transmitter for the hydraulic pressure in the hydraulic press cylinder, a set point transmitter, and a control valve, actuated by the deviation of the actual value from the set point value, for the hydraulic cylinder by means of which the press table is moved. In order to produce a simple and inexpensive control circuit compared with conventional control circuits, in which the control valve is a complicated and expensive servo valve, the control valve is a pressure controlling proportional valve and the circuit can be designed to provide an arbitrary, e.g. rectilinear, control curve-with the position of the press table as a function of the time-during at least the high-pressure part of the closing sequence of the press.

Abstract: A method of determining the switch-over instants of static converters, which are connected in parallel opposition and free of circular currents, of a multiphase controlled inverter feeding asynchronous motors at variable frequency in four-quadrant operation, serves to ensure that a correctly timed switching-over of the converters takes place without having to take into account the operating frequency during a smoothing of the current measurement value. For this purpose the Fourier transforms of the fundamental oscillation of the currents are formed in component form from the temporal courses of the individual currents of the multiphase system with the use of auxiliary magnitudes, which are of constant amplitude and free of harmonic oscillations, as multiplier function. Subsequently, the Fourier transforms of the fundamental current oscillations of all phases are added separately according to the active and the reactive components. The quotient of the temporally smoothed sum values or its arc tagent is compared with the running time angles and the switching-over of the parallel opposition circuit is initiated at each instant of the equality. <IMAGE>

Abstract: In a noise radar a pseudo-random sequence is generated repeatedly and used to phase modulate a transmitted signal. The transmission is interrupted during a number of periods during each pseudo-random sequence which allows returns from targets to be received from the same antenna as is used for transmission during those periods of interruption. Each transmitted pulse, between successive periods of interruption, contains a different selection of successive digits of the code thus increasing the apparent randomness of the transmitted code and making detection more difficult.
