Title: Toolholder for use in a rotary crop-cutting machine
Inventor: JETZINGER FRANZ
IPC: A01D34/73
Filed: 1991-11-14
Abstract: ABSTRACT            TOOLHOLDER FOR USE IN A ROTARY CROP-CUTTING MACHINE               A toolholder for use in a rotary crop-cutting machine, such as a mowing or chopping machine, comprises a ro-tatable tool carrier, to which the tools are adapted to be pivoted on pins, which are parallel to the axis of rotation of the tool carrier. Each of said pins carries at least one tool and at opposite ends is radially slidably mounted in axially aligned slots, which extend radially with respect to the axis of rotation and are formed in two axially spaced apart lugs, which are secured to and substantially radially protrude from the body of the tool carrier, or in two axially spaced apart disks, which constitute the tool carrier. Each of said slots has a radially outer portion for retaining the associated pin against axial displacement in said radially outer portion. In order to ensure that a detaching of the tools will reliably be prevented even if the lugs or disks are very thin, each of the two axially spaced apart and axially aligned slots of each pair has a constricted radially outer portion, each end por-tion of each pin has a diameter that corresponds to the un-constricted width of the slot, the constriction is defined merely by project10ns, which are formed on the side faces of each slot on that side which is nearer to the other slot of the same pair, and the pins are formed with recessed portions for receiving said projections.

Abstract: An arrangement to prevent a premature ignition of an active charge, which is to be ignited by means of an adjustable time-delay fuze and belongs to a projectile that is expended from a firing barrel by means of a propellant charge, is provided which is based on a mechanical and a pyrotechnical safety element.   In so doing,  the ignition path between a first delay element ignited while firing and the active charge of the projectile can be blocked by a barrel probe that can be moved at right angles to the firing direction and that in its position blocking the ignition path can be arrested by an acceleration probe that can be moved counter to the firing direction and, as long as the projectile is located in the firing barrel, by the firing barrel wall.  A second delay element, that can also be ignited while firing and exhibits a shorter delay period than the first delay element, pressurized the barrel probe with gas pressure in the direction of  its end safety position following expiration of its delay period.

Abstract: A pressure sensitive control device having a housing made up of a plurality of housing members, a diaphragm, a bistable snap-disc, a switch and an actuator.      T'he snap-disc moves from one configuration to another upon application of pressure over a predetermined amount to drive the actuator which moves the switch from its normal operating position, which can be either closed or open, to a tripped position, which is opposite its normal operating position. Two adjacent housing members, which support the snap-disc and switch, respectively. are formed with cooperating spacers which allow the spacing of these housing members to be continuously varied over a small range of adjustment to allow the switch point of the control device to be adjusted after partial assembly of the control device. The diaphragm and some of the housing members may be subassembled for testing the components of the control device prior to complete assembly. The switch is initially formed as one piece and electrically halved after subassembly with one of the housing members. A housing member which is formed for connection to an electrical control circuit to which the control device is to be attached as modular and can be replaced with similar housing members which are configured for connection to different types of mating electrical connectors associated with different control circuits.      Methods of assembly are also enclosed.

Abstract: In a stud and socket combination for studded footwear, a moulded plastics socket (1) provides a threaded axial hole (5) bounded byan inner ring (9). A co-axial outer ring (10) is radially separated from the inner ring to leave an annular space (11). A plastics stud moulding (19) comprises an externally threaded sleeve (21)which can be screwed into the socket hole and a co-axial ring (26) which is spaced radially outwards from the sleeve to slide over the inner socket ring (9) and enter the annular space (11) whenthe stud and socket are assembled. Four part-cylindrical webs (29) project axially from the ring (26) into the space (11) and provide four axially-extending locking ribs (28) at 90° intervals which project radially outwards from the ring. On the inner surface of the outer ring (10) of the socket are formed four corresponding formations providing recesses (15) to receive the ribs (28). Each recess is bordered on one side by a lead-in ramp (16) and on the other side by a stop block (17). When the stud is screwed into the socket the projections ride over the ramps in turn, offering increasing resistance to rotation successively, until finally the projections engage the stop blocks (17) to prevent further rotation.
