Patent DE-3121163-A1 (DE)
Title: Hammering tool, in particular for the driving-in of securing bolts
Inventor: EVERTZ EGON
IPC: B25C1/00
Filed: 1981-05-27
Abstract: A hammering tool provided for the driving-in of securing bolts is designed according to the invention in such a way that, by using a valve body with a hollow chamber, the opening of the cylinder, in which the hammer ram is acted on, is to a large extent freed even upon only a very slight movement of the valve body from its closure position. This makes it possible, in the case of a low overall weight, for the hammer ram to assume a particularly high kinetic energy along its acceleration stretch inside the cylinder and to output this energy for driving-in of the bolts. With a safety control means it is possible to prevent an impact being released by a finger trigger when the hammering tool is not in place. For this purpose use is made of a sensor pin which interacts with a valve attached to the compressed air source in such a way that, only when the hammering tool is in place, and the sensor pin inserted, is the state of readiness achieved in which it is possible to activate the finger trigger, which then effects the movement of the valve body into the open position via an operating cylinder.

Patent DE-3125184-A1 (DE)
Title: Electrooptical measuring device
Inventor: MUETSCH ADOLF
IPC: G01D5/38
Filed: 1981-06-26
Abstract: Electrooptical measuring device having a glass scale and a relatively displaceable scanning head which has at least three successive scanning gratings which are transparent in the manner of a window and are phase shifted by 120 DEG  or 60 DEG  relative to one another. The scanning gratings have the same grating grid and the same line width per graduation line as the glass scale. Each scanning grating is assigned a light-emitting diode and an electrooptical transducer at the same level. The grating grid (r) satisfies the relationship r = n .2x. The resolution x is 1  mu , the grating grid 6  mu  and the line width 3  mu . Only one voltage value is tapped per sinusoidal curve at the transducer output, specifically in the middle region in the case of the largest change in voltage per displacement unit. An exactly sinusoidal optical contrast as a function of the displacement is therefore not a prerequisite for accurate measurement. Given good optical contrast, it is possible to double or quadruple the individual pulses, that is to say the measurement accuracy, by respectively tapping 2 and 4 voltage values per curve. The evaluating electronics are simple, light, small, inexpensive and insensitive to voltage fluctuations.

IPC: D21G9/00
Filed: 1981-08-13
Abstract: A first group of cylinders of a paper machine comprises a plurality of drying cylinders (11-14) on which the paper web (6) travels successively. Only one face of the paper web passes on the cylinders (11-14); the other face is constantly in contact with an endless drying belt (9). Between each pair of cylinders, the bands, i.e. the belt (9) and the web (6), pass together on a guiding roller (16-18). The cylinders (11-14) are located outside the loops formed by the belt (9), and the rollers (16-18) are located inside. The guiding rollers (16-18) arranged between the drying cylinders are sucking cylinders; their suction chamber (32) extends above the contact area between the drying belt (9) and the paper web (6). Thus, the machine may operate at a very high speed since the web (6) is maintained by suction (32) against the belt (9) when it travels on the rollers (16-18), against the centrifugal force exerted on the paper web.

Title: Device for thermal analysis of emission gas
Inventor: HENTZE GUENTER DIPL PHYS DR
IPC: G01N25/48
Filed: 1982-07-17
Abstract: During combined thermal-analytical and mass-spectrometric investigations the problem exists that the gaseous components which are released from the sample are transferred into the mass spectrometer (11) with no sensitivity loss as far as possible, it being unacceptable for the constitution of the gas to be changed en route from the sample chamber (3) of the DTA measuring head (1) to the mass spectrometer (11). Since, as a rule, the DTA measuring head (1) is at reduced pressure, normal pressure or increased pressure and a high vacuum prevails in the mass spectrometer (11), a large pressure change must be overcome. To this end, shutters are provided, with the first shutter (13) being fitted in an inner tube (6) in which the DTA measuring head (1) is located, and the second shutter (14) being arranged in an outer tube (8) which surrounds the inner tube (6). In the intermediate space (9) between the two tubes an initial vacuum prevails, while the high vacuum associated with the mass spectrometer (11) prevails on the outside of the outer tube (8). The gas to be investigated flows through the first shutter (13) out of the sample chamber (3) of the DTA measuring head (1) into the space (9) between the two tubes (6, 8) and the majority of it is sucked out by an initial vacuum pump. A smaller portion passes through the second shutter (14) into the high vacuum and passes as a molecular beam (15) into the ion source (12) of the mass spectrometer (11). <IMAGE>
