Patent EP-0021170-A1 (EP)
Inventor: BUCHNER BERNHARD DIPL-ING
IPC: F02B25/12
Filed: 1980-06-04
Abstract: A two stroke internal combustion engine with at least one dual piston, the cylinders of which are connected to each other by a combustion chamber on the cylinder head side. The engine can be charged on the crank chamber side with an air or air/fuel mixture by a turbo or supercharger. Both the leading and trailing pistons of the dual piston construction control the process of transfer of the air or air/fuel mixture through a transfer port from the crank chamber side of the cylinders to the combustion chamber side of the cylinder for the trailing piston as well as the exhaust process such that the exhaust process begins before the initiation of the transfer process. The engine can operate on either the Otto or Diesel cycles and use multiple fuels.

Abstract: A pipe (3,4,5,6) connecting the equipmentto be protected with a vessel (1) is locally divided in two paths (4 and 5), a pump (8) and a no return valve (9) being mounted in one path (4) and an electro-magnetic valve (10) in the other path (5). Pump (8) and electric valve (10) are controlled by a contact manometer (11) so to fill or to empty the vessel (1) depending on the pressure in the equipment. 
     The liquid body in the vessel (1) moves a diaphragm (15) between a position above the pipe (3,4,5,6) connection but below a discharge opening (24) and a position above this opening (24), in which latter position liquid is discharged through a siphon (25) provided on the opening (24). 
     The diaphragm (15) divides the vessel (1) in two spaces (16 and 17) and is the bottom of a bag (18) secured to the vessel (1). 
     Afloat (28) in a container (30) connected to the vessel (1) opens a feeding valve (29) when the liquid level in this vessel (1) is beneath a determined value.

Abstract: A spiral type one-way clutching mechanism utilizes a monolithic annular outer body member (11, 31) having an inner surface (15, 35) of spiral configuration defining an axially oriented opening therein. A monolithic annular inner body member (16, 36) is concentrically positioned in the axially oriented opening and has an outer surface (34) of spiral configuration which is tangentially congruent to the outer body inner surface, the spiral surfaces defining a spiral race (21, 41) therebetween. At least one of the inner (16, 36) and the outer (11, 31) body members have a radially directed slit (17, 37) extending therethrough. The outer body member (11, 31) and the inner body member (16, 36) are relatively rotatably oscillatable with respect to each other. A plurality of axially oriented rollable wedging members, e.g., abutting roller members (22, 42), is positioned in the spiral race (21, 41), each such member being in contact with the inner and the outer spiral surfaces. Structure (20) is provided which acts between the body members, e.g., at least one limit spring (18, 38) for limiting the relative oscillatory movement therebetween. 
     This mechanism is thus insensitive to transverse forces; substantially eliminates overrunning frictional wear on the critically shaped surfaces of its members; and substantially eliminates the role of chance in establishing the clutching load distribution between its members. The mechanism may be used in a clutch assembly with both active and passive clutching modes.

A hydraulic jack (23) is connected between a pin (26) on lever (12) and a fixed bracket (18), which also carries pivot (12a), and operates to move the tail-board in a horizontal attitude between the ground and the vehicle floor level, and a second jack (22) is connected between bracket (18) and a crank arm (21) of lever (14) and operates, when the platform is at vehicle floor level, to move lever (13) bodily in an arcuate path about pivots (12a and 12b and 12c) to swing the tail-board into a vertical attitude. A ramp (35) pivotally attached to the tail-board is movable into positions aligned with and at right angles to the tail-board to facilitate loading, to prevent a load from slipping or rolling off, and to form an upright extension of the tail-board.

Abstract: The quality and strength of a spot weld can be correlated to a drop in resistance during the fusion process. Rather than measuring this resistive drop at the welding electrodes by attaching external sensing means thereto, a control system makes use of the phenomenon that a resistive drop also causes a change in the total load power factor further resulting in a change to the current extinction angle of a weld half cycle. By determining the amount of increase or decrease that has occurred in the current extinction angle during a weld or a group of welds, a basis for the control of the welding heat is obtained. The power factor monitoring and control system is used for controlling the quality of a spot weld made in the automotive industry on assembly line welders.
