Abstract: DRIVING CIRCUIT FOR RADIO FREQUENCY DRYER                 Abstract of the Disclosure A driving circuit for supplying a radio frequency electrical signal to the applicator section of a radio frequency dryer includes a voltage controlled oscillator, supplying a signal to an amplifier circuit.  The amplifier circuit supplies an amplified signal to the applicator section of the dryer via an impedance match circuit.  The signal supplied to the applicator section is compared in phase with the output of the voltage controlled oscillator and phase deviations are utilized to produce a signal which controls the frequency of the voltage controlled oscillator output, such that the applicator section of the dryer is driven at its resonant frequency.

Abstract: ABSTRACT OF THE DISCLOSURE   The top closure of the present invention comprises a flexible sheet member sized to fit in covering relation over a top opening of a box.  One edge of the sheet member is attached to the upper edge of one of the box walls.          At least one track is positioned at one of the opposite ends of the box and an elongated shaft extends between the two opposite ends of tile box.  The tracks guide the shaft from an open position adjacent one edge of the box to a closed position adjacent the other upper edge of the box. The flexible sheet member is rolled around the shaft when the shaft is in its open position, and the sheet member unrolls from the shaft as the shaft rolls towards its closed position.          When the shaft reaches its closed position, it engages a plurality of flaps which are mounted along the edge of the box.  These flaps wrap around the shaft as the shaft rotates, and become attached to the shaft, thereby fastening the shaft to the sidewalls of the box with the tarpaulin in covering relationship over the opening.  Reversal of the rotational direction of the shaft causes the flaps to unroll and detach from the shaft so that the shaft can roll back towards its open position, and thereby uncover the opening in the box.  The shaft may be rotated either by an electrical motor or by a manual crank.   The motor has a gear box which functions as a brake against rotation when the motor is deactuated.

Abstract: ABSTRACT OF THE DISCLOSURE A grass catcher for collecting clippings from a rotary mower that is mounted beneath a riding vehicle and has a clipping outlet opening to one side of the vehicle comprising an upwardly opening clipping receptacle on the rear of the vehicle; extending across substantially the full width of the vehicle, and a duct extending rearward and upward from the clipping outlet along the side of the vehicle and having a rearmost portion that comprises an elbow which defines a duct outlet.  The grass catcher has substantially rigid supporting structure on the vehicle for supporting the clipping receptacle. The duct outlet defined by the elbow is supported by the supporting structure at the one side of the vehicle, above the receptacle, and opens substantially towards the other side of the vehicle.  A cover is hingedly connected with the supporting structure to swing between an operative position overlying the receptacle and the elbow and an inoperative position clear of the receptacle. The cover has deflection means thereon for controlling the trajectory of clippings issuing from the duct outlet to constrain them to move downward into the receptacle.  The deflection means comprises:          (1)  a top wall on the cover at a level above the duct outlet; (2)  a side wall at each side of the vehicle projecting down from the top wall to substantially the level of the top of the receptacle; (3)  a front wall extending between the side walls, projecting down from the top wall to near the front upper edge of the receptacle and being forward-ly adjacent to the duct outlet, and (4)  an elongated baffle projecting edgewise downward from the top wall a distance to have a bottom edge spaced above the top of the receptacle but below the top of the duct outlet, the baffle having opposite ends inwardly adjacent to the side walls.  The baffle end at the one side of the vehicle is rearwardly adjacent to the duct outlet, and at the other side of the vehicle is in rearwardly offset relation to its first mentioned end, so that the baffle cooperates with the top and front walls to define a diverging channel that extends from the duct outlet towards the opposite side of the vehicle.

Abstract: Abstract of the Disclosure A transfer arrangement for stepwise advancement of work-pieces includes gripper rails, each of which is constituted by at least one machine-sided gripper rail section, and at least one tool-sided gripper rail section, which are connected to one another by a coupling mechanism in a rigid but selectively releasable manner.  A clamping rod which extends in its clamping or engagement position across a separating location between the associated gripper rail sections serves as a connecting element of the coupling mechanism.  The clamping rod has a clamping head which engages behind a holding surface of an end portion of one gripper rail section, while being carried by the other gripper rail section.  The clamping rod is supported in the other of the gripper rail sections for axial displacement and for rotation, and can be tensioned in its coupling position between the then coupled gripper rail sections.  In one of its rotated positions, in which the clamping head of the clamping rod is out of contact and out of alignment with the holding surface of the end portion, the clamping rod can be extracted out of its engagement position to provide for a trouble-free separation of the gripper rail sections from one another.

Abstract: ABSTRACT OF THE DISCLOSURE           Instead of embedding a sensitive component in the usual manner in a casting compound, use is made of a prefabri-cated protective housing comprising a prefabricated housing element into which the component is initially inserted with a certain amount of play.  The deformation-area of the housing element is deformed plastically in order to clamp the compo-nent in the axial direction.  A resiliently deformable cover is then secured to the housing element, in order to keep the said component pressed radially against a seat.  The protec-tive housing is particularly suitable for use in appliances containing explosive substances since, during the embedding process, no dangerous work-materials are used, nor do any aggressive resin-components appear subsequently.
