Granted: 1986-01-21
Abstract: ABSTRACT OF THE DISCLOSURE           Agricultural Implement Convertible Between Use and Transport Positions An agricultural implement includes an elongated carrier frame with support wheels.  One or more tool sections, each having tools mounted to a tool mounting bar, are mounted to the carrier frame.  The tool sections are independently raised and lowered between the transport and use positions by hydraulic cylinders.  The carrier frame is attached to a tractor by a hitch assembly which includes a control link.  With the tractor in the use position, the control link steers the support wheels in the forward direction.  In converting the implement for transport, an hydraulic cylinder actuated by the operator from the tractor, uncouples a portion of the hitch assembly and permits the control link to rotate as the tractor is driven to the side of the carrier frame.  In thus rotating, the control link actuates the steering mechanism to turn the support wheels so that they all face the side and are aligned with the tractor which transports the implement from the side, parallel to the direction of elongation of the carrier frame.  As the tractor turns during transport, the control link and steering mechanism steers to support wheels.

Abstract: ABSTRACT OF THE DISCLOSURE           An automatic document handling system 20 for recirculative precollation copying in reverse serial order of a set of simplex document sheets on a simplex and duplex copier 10 to provide precollated simplex or duplex (two-sided) copies with proper orientation of the document images on the outputted copy sheets 128 for copies made on preprinted, prepunched, or other special orientation restricted copy sheets, as well as for copies made on plain paper or other non-orientation sensitive copy sheets. The copier 10 has a special copy sheet supply 107 for said special orientation restricted copy sheets and a main copy sheet supply 106 restricted to conventional non-orientation sensitive copy sheets.  Switching systems, e.g. 200, provide for selecting between the feeding of copy sheets from the main supply 106 or the special copy sheet supply 107 and for selecting between simplex or duplex copying, and connect with overall control system 100. The control system 100 causes the document handling system 20 to circulate the set of document sheets once before copying them, to count them and determine whether there are an odd or even number, only in response to both the first switching system 200 selection of the special copy sheet supply 107 rather than the main copy sheet supply 106 and the selection of duplex copying rather than simplex copying. The former selection is automatically removed after each copying run. If copies are made from the main tray 106 copying begins on the first circulation of the documents. Thus this system improves the efficiency of systems such as that of U. S. Patent 4,330,197 and 4,278,344.

Abstract: ABSTRACT OF THE DISCLOSURE            The present invention relates to a method for sealing capsules to render them both tamper-proof and tamper-evident.  The method comprises locating a quantity of an adhesion-promoting fluid between the adjacent surfaces of the overlapping capsule wall, and thereafter applying dielectric heat energy in the vicinity of the adhesion-promoting fluid, to cause the adjacent surfaces of the capsule walls to form a permanent bond. Preferably, the adhesion-promoting fluid may comprise a non-solvent for the capsule walls that further has a high dielectric constant.  Suitable adhesion-promoting fluids include lower alkanols.  The method is capable of rapid operation and is inexpensive by virtue of its simplicity. Reliable capsule seals are achieved that are incapable of violation.
