Title: Printing blanket deformation characteristic measurement - is by measuring indentation distance of convex pressure piece into tensioned blanket
Inventor: MARCHNER LUDWIG JOSEF
IPC: B41F33/00
Filed: 1978-11-03
Abstract: The measurement device for determining the deformation characteristics of a print blanket, esp. for offset printing, enables the maximum print press. value to be optimised. This ensures optimum printing colour transfer. Two pressure pieces (5, 13) movable w.r.t. each other have opposing convex coaxial surfaces. The print blanket (15) is drawn across the convex surface of one of the pressure pieces (5) by a tensioning arrangement (17, 19, 23) producing a defined tension. The press. pieces are forced together by a loading arrangement (31 to 35) producing a normal force of known magnitude. A distance measurement indicator (9) slows the degree of impression of the upper press. piece (13) in the tensioned print blanket. The press. pieces are in the form of cylinder segments. Both, and least the one (5) on which the blanket is tensioned, are replaceable.

Patent DE-3010058-A1 (DE)
Inventor: STEGMANN HORST DIPL PHYS
IPC: G01N29/024
Filed: 1980-03-15
Abstract: The measuring arrangement for determining terrestrial refraction is applied in geodesic measurements (trigonometric altitude transfers, in staking out and in precision tachymetry, steering construction machinery by means of a laser beam, precision levelling). The measuring arrangement includes a geodesic measuring instrument (T), an electronic processor and an appliance (S, E) for measuring the transit-time difference of sound waves. After the sound waves generated by a sound transmitter part (S) have traversed layers of air (e.g. at different altitude) on a representative path, the time difference is measured and employed to determine the refraction. The sound receiver part (E) includes two microphones (M1) and (M2) which are positioned vertically above one another at altitudes (Z1) and (Z2) above the surface of the earth in the immediate vicinity of the electronic tachymeter. Using the arrangement it becomes possible to determine, for a particular range as defined from the position of the instrument, continuous measured values from which the instantaneous refraction can be inferred. Terrestrial refraction can be determined more accurately than in conventional methods for engineering geodesic and constructional work. <IMAGE>

Title: Electromagnetic drive for camera shutter - has thin rotor of epoxy! resin and narrow magnetic field gap
Inventor: HIROHATA MICHIO
IPC: G03B9/08
Filed: 1980-08-07
Abstract: The driving rotor of a shutter consists of a thin plate formed from a transparent, thermosetting, epoxy resin. A heat treatment operation is carried out after the etching process to produce the conducting coil pattern, and the magnetic field of the stator is reinforced by making the gap of the magnetic field narrow. The heat treatment accelerates the polymerisation process and is carried out in an atmosphere of nitrogen to prevent oxidn. of the conductors. The reduced dimensions of the stator make for a magnetic field of ample size, and the coefft. of electromagnetic conductivity is as great as possible, with the rotor thin and well flattened.

Title: Pulsed argon fluorine excimer gas laser - with avalanche transverse discharge in portable, battery-driven gun form
Inventor: POPESCU-GOETSCH FLORIAN RAUL D
IPC: H01S3/097
Filed: 1980-08-20
Abstract: Pulsed Ar-F excimer gas laser with avalanche transverse discharge is in the form of a portable, battery-driven gun with systematic parametric resonance on pumping the pulsed operation. The greater oscillation amplitudes of the stimulated mols. and atoms are controlled(energetically)by this type of resonance to enhance the light emission, and thus like a thyristor, oscillate damped as a system of micromotors in the framework of an overall function tensor with main protagonists in the time average value having the density- space-time dimension rho L exp. 6.5 T exp. -3.5 in the absolute system of dimensional analysis. The tensor is energy saving and acts esp. as radiant energy dynamic tensor with coprodn. of a special microwave needed above all for self- protection against attackers as additional action and for dynamisation of the light effect of the emitter photons, which thus incorporate additional pulsations with physiological effect. Accurate and variable resonance is possible and small amts. of battery energy for short intervals give very great power.
