Abstract: A drive and drive controller for a vibratory conveyor, wherein the drive comprises a pair of pole pieces (52, 54) offset along a direction of action of the drive, and moveable in the direction of action of the drive when energized by a power signal. Preferably, one of the pole pieces (52) is mounted to a tray portion (22), and the other (54) to a kinetic balancer portion (56), of the conveyor. The power signal comprises a series of pulse trains of controllable frequency and duration, whereby the drive unit may be vibrated at a controllable frequency and amplitude so that the vibratory conveyor may be readily tuned to optimal performance. Optionally, the voltage level of the power signal may be reduced by an autotransformer in series with the power signal to independently control the power level.

Abstract: A carburetor with an idling system is designed so that the full pressure differential or gradient available between approximately ambient pressure and the vacuum in the intake tube is employed for producing a critical pressure ratio of a supersonic flow in a laval nozzle. To make this possible, a fuel air emulsion formed with primary air is introduced from a mixing duct via a constricted orifice of a tubular nozzle at a bore constriction, at which there is always a sonic velocity when there is a critical and supercritical pressure ratio, into the secondary air flow where it is superfinely atomized in the secondary air flow, with a maximum velocity differential, aided by subsequent pressure surges. At least at a point far into the partial load range of operation, the idling system produces a homogeneous mixture which is homogeneously distributed in the intake tube with a practically molecular state of division so that it is even supplied to all cylinders of the engine and completely combusted with a minimum production of contaminants.

Abstract: The flow rates in the cooling circuits of the apparatus can be controlled with the aid of a computer by means of ceramic turning valves. The computer is connected to the central computer of a plastic injection molding machine. The valve body disks, lying under constant pressure via ceramic sealing surfaces against valve seat disks, can be turned by means of pulse-controlled electric motors. Each fitting has a valve channel between the channel section of the supply channel and the channel section of the discharge channel which is covered by a valve seat disk and which forms a valve chamber. This achieves the effect that the deviations from the set temperature in the temperature-critical zones can be substantially reduced with acceptable technical expenditure. The temperature constancy achieved may be maintained for a virtually unlimited time without appreciable maintenance work.

Abstract: In the method of making expanded foodstuffs in which a dough emerges from the nozzle of an extruder and the extrudate is subjected to an after-treatment in a hot medium, the extrudate is kept after emergence from the nozzle at a temperature which corresponds substantially to the emergence temperature of the dough and the after-treatment takes place directly after the extrusion. In particular the dough can be extruded directly into hot oil or fat. Since after the extrusion no cooling of the extrudate takes place, in particular by water evaporation, the extrudate can be further expanded in the a after-treatment and a foodstuff is obtained with a texture which is identical to the texture of foodstuffs which after the extrusion and prior to the treatment in a hot medium have been subjected to a drying process.

Abstract: Modern infrared radiation detectors have a coverage angle of up to 180 DEG . Such a wide coverage angle is not always required, since interfering sources which are located outside the area under surveillance are occasionally detected in its peripheral area.
