Patent DE-3239586-A1 (DE)
Title: Electronic typewriter
Inventor: SMITH MICHAEL
IPC: B41J29/36
Filed: 1982-10-26
Abstract: An electronic typewriter is specified which has a keyboard which provides electric output signals according to the keys actuated. An electronic control system causes a daisywheel to print out corresponding characters. During the printing of each character, the daisywheel moves horizontal by one character spacing and can be returned in each case by the character spacing. A memory register in the electronic control system memorises a number of characters printed last and continues to write the contents of its memory. If an error is made, the daisywheel can be returned to the error position and the erroneously printed character can be called up from the register and hit again via a correction ribbon in order to delete the error. A semi-step control key is provided in order to move the daisywheel horizontally forwards by half a step spacing so that it moves outside the normal character alignment and special characters can be inserted in an existing space on the paper.

Title: Monitoring and evaluation device for fault and multiple-sheet monitoring and measurement of thickness
Inventor: FOERSTER KARL-HEINZ
IPC: G01B7/06
Filed: 1983-01-07
Abstract: The invention relates to a monitoring and evaluation device for fault and multiple-sheet monitoring and measurement of the thickness of sheet-like or web-like materials in processing and manufacturing machines. The object of the invention is to produce a vibration-compensating device which requires fairly small sensors and carries out evaluation in such a way that only comparative values for one side of the transporting line are required. The object is achieved by having at least three sensors on the basic body, arranging the latter to the side of the material transporting line, having the object of the measurement which is to be monitored in one of the two outside sensors at the time of measurement and having downstream of this arrangement an evaluation device, serving for the evaluation and determination of the measured values with regard to changes in measured values due to mechanical vibration and changes due to the presence of the object of the measurement in the sensor. As a result of the invention, the outlay or material and assembly time are reduced and the dimensions of such devices are reduced. Sensitivity can also be increased by the possible use of inductive sensors. <IMAGE>

Title: Device for demonstration of the action of the brake device in a wheeled vehicle
Inventor: SCHLEGEL MARTIN
IPC: G09B25/02
Filed: 1983-12-24
Abstract: On a demonstration panel (1) four wheel elements (3) are rotatably mounted on parallel axles (2). Their disc brakes (4) are each connected to a brake governor by way of a brake lever (59). A drive shaft (13) bears on each wheel element at the bottom, which shaft, rotatable about its axis (34) sits in a bearing element (29), which in turn, is supported so that it can swivel about a horizontal swivel axis (32) perpendicularly intersecting the axis (34). A belt pulley (17) for a flat belt (18) is supported on the drive shaft (13) symmetrically in relation to the axis intersection (34, 32), which belt runs round all four belt pulleys (18) and about a drive pulley of a flywheel driven by an engine. In order to adjust the bearing force on the wheel element (3) a threaded spindle (39) is used, which by means of its pivot nut (38) swivels a connecting piece (37) about the joint (36) of the bearing element (29), thereby adjusting the prestressing force of a balancing spring (47) which on the other side of the swivel axis (32) acts on the bearing element. The slip limit for the transmission torque is adjusted on the handwheel (15) by way of the bearing force between drive shaft (13) and wheel element (3). If the brake is operated after switching off the drive, wheels with a smaller transmission torque come to a standstill sooner. In this way a braking sequence on ground with varying adhesion or with antilock systems can be demonstrated. <IMAGE>
