Inventor: BAUER F
IPC: F16J9/00
Filed: 1979-06-29
Abstract: A piston for internal combustion engines, especially for high-performance internal combustion engines. The piston has several ring grooves for piston rings, and an oil control groove which is provided below the top ring groove, is separated therefrom, and opens only towards the cylinder bore. The land between the topmost ring groove and the oil control groove, seen in cross section, is designed as a support having constant bending stress and has a finite height at its outer surface. The inner confine of the oil control groove has a finite radius or rounded-off section to avoid an increased stress concentration factor.

Abstract: Method in producing stapled printed matters. Signatures are laid astride one upon the other on a conveyor path (10) in a number of stations (12, 29, 34) distributed along the conveyor path. The signatures are transferred along the conveyor path at a rate which is brought to vary cyclically between a lower value while signatures are being received, and a higher value while signatures are being transferred between the stations. The signatures laid one upon the other are stapled and trimmed by operative movements allowing the signatures to be transferred continuously along the conveyor path while being stapled and trimmed.

Abstract: An apparatus for discharging cinders from an incinerator has an upwardly open intake pit having horizontally spaced front and rear walls. A water-filled trough is provided below this intake pit and has an upwardly concave floor and defines an upwardly extending outlet for cinders which have been quenched after they have dropped down in the pit into the water in the trough. A stepped plunger has a front face slidable in an arcuate path along the floor of the trough between a retracted position relatively close to the front wall defining the pit and an advanced position relatively far from the front wall. This plunger also has an upper surface on which is provided a step having a face which lies in back of the front wall in the retracted position of the plunger and between the walls in the advanced position. Thus as the plunger is advanced from the retracted to the advanced position the step pushes large objects against the rear wall of the pit and compresses these large objects. In addition, this step is inclined so as to exert a downward component of force on material in the pit and press it against the floor of the trough.

Abstract: A device for torsion-proof connection of a number of elements (11, 12) in direct or indirect rolling contact with each other, which together make a robot arm or the like, whereby the elements are held together and actuated by force transmitting actuators, for example cords. The object of the present invention is to provide a device with which the individual elements of a robot arm can be torsionally locked so that it can bear significant torsional forces without detoriating the rolling characteristics of the elements. This object has been achieved by the fact that the elements (11, 12; 15) pairwise, with their rolling surfaces (13) turned towards each other, being connected with each other through a torsion member (14) which is flexible and/or joined in the rolling direction of the elements (11, 12) and which has a great stiffness across the rolling direction.

Patent SE-8206784-L (SE)
Inventor: OHLIN E
Filed: 1982-11-29
Abstract: The equipment comprises a pump, a valve, and a drive device. In the pump, a piston moves, with its stroke determined by the contact of a fixed ring against the cylinder, and that of a movable ring against a fixed stop. The piston is activated by a sprung driver moving freely on the piston connecting rod between the rings. The piston stroke length, and thus the pump volume, are determined by adjustment of the movable ring. The greater the distance between the rings, the longer the path of travel of the driver, and the less the piston stroke. In the suction position, where the sprayer involved is filled with dilution fluid via channels, a measurement channel is filled simultaneously with sample fluid which is sucked through appropriate channels. Through valve rotation, the sample volume in the measurement channel is sprayed together with a determined volume of dilutant fluid, and the required dilution is achieved.

Abstract: A dual word line, electrically alterable, nonvolatile floating-gate memory cell has a word-line-to- floating gate capacitance (C3) which is significantly greater than either the program-line-to-floating gate capacitance (C2) or the floating-gate- to-substrate capacitance (C1). This allows the program line (46) and the word line (50) to be counter-driven to minimize coupling to the floating gate (42) during the write/erase cycle and to maximise coupling during the read cycle. The net result is higher write/erase/read efficiencies than heretofore possible. <IMAGE>

Abstract: A method to influence an audio source during telephone calls, and a device for utilization of the method, whereby the sound volume of the audio source is being reduced in connection with incoming telephone signals, as well as during the period of time that the receiver of a telephone (B) is being lifted. According to the invention, a signal status indicating unit (A) is connected to the wiring circuit of a telephone (B), said unit being arranged to indicate both incoming telephone signals as well as lifted telephone receiver. The signal status indicating unit (A) is preferably arranged to maintain the output signal also during the time interval existing between two successive telephone signals. Said output signal is transmitted, wireless or by wire, to connect a shunting resister (G) in the loudspeaker circuit for which a reduced sound volume is intended, and by loudspeaker is also included the audio circuit existing in the audio source, in which the shunting resistor (G) can be included as an integrated member. When an output signal from the signal status indicating unit (A) no longer exists, the shunting resistor (G) is disconnected from the audio or loudspeaker circuit, thereby restoring the original sound volume.
