Filed: 1989-08-19
Abstract: Sepn. and detection of components of a substance mixt.  by temp. gradient gel electrophoresis (TGGE) comprises (a) setting up the temp gradient by either (i) setting up a spatial temp. gradient in the direction of the electrical field to be used for the sepn. using at least two temp.  levels spatially sepd. from one another; or (ii) setting up a time temp. gradient by temporal variation of the temp.; or (iii) setting up a temp. gradient by a  combination of spatial and time temp. gradients; (b) transmitting the temp. gradient to the gel matrix through a sepn. material including in a heat conducting thermostat jacket and either (i) maintaining the spatial temp. gradient using regulable heating or cooling devices so that the energy flow through the heating device is greater than that through the cooling device and this energy flow  is in its turn greater than the heat exchange with the sepn. material enclosed in the thermostat jacket or (ii) setting up the time temp. gradient in the sepn. material in each position of the sepd. stretches in temporal dependence using one or more regulable heating or cooling devices so that the energy flow through the heating or cooling devices is greater than the heat exchange with the sepn. material enclosed in the thermostat jacket; and (c) detecting the sepd. components at the end of the sepn. stretch.
Patent DE-3930245-A1 (DE)
Inventor: ZETTL OTTO
IPC: B23B31/02
Filed: 1989-09-11
Abstract: A tool support (1) is detachably fastened to a tool holder (14) by means of an open-ended clamping ring (16). The clamping ring (16) is guided in an annular groove (32) of the tool holder (14). To couple the tool support (10), the diameter of the clamping ring (16) is reduced by means of an actuating device acting on it tangentially. The radial movement of the clamping ring (16) is converted into an axial stroke of the tool support (10). The latter is thereby clamped in a positive-locking manner against the tool holder (14). In the process, the clamping ring (16) is supported at one side on the annular groove (32) of the one tool part (14) and bears with a clamping face against the other tool part (10) in a positive-locking manner.

Title: Imaging by NMR using general gradients - interpolating sampled values to fit distortion-free digital K-space matrix
Inventor: BRUDER HERBERT
IPC: A61B5/055
Filed: 1990-02-06
Abstract: The currents which pass through the coils produce the strong magnetic gradient temporarily superimposed on the permanent magnetic field. In a condition of resonance the coils pass more easily high current values. However, these badly distort the resulting echo waves unless the time-equidistant sampling is transposed into a K-space based matrix. In an alternative method, the sampled values are submitted to a Fourier transform, and only those samples are used which are found to be closest to the established sampling points in an equidistant K space raster.
Patent DE-4024540-A1 (DE)
Inventor: MATZAGG ERICH
IPC: F42B8/20
Filed: 1990-08-02
Abstract: There is proposed an ejector device (6) for grenade projector or mortar projectiles (1), which permits simulation of mortar firing even in halls or very limited areas. It is known that blank cartridges (17) for rifles, pistols or bolt firing devices have only a slight degree of scatter in terms of gas pressure. Therefore the ejection speed of a piston (13) which is inserted into the ejector device (6) and which is driven by the powder propellent gases of the blank cartridge (17) is always the same. In that way it is always possible to achieve the same firing ranges of only a few meters.

Title: Directly measuring fuel flow to ship's engines - using measuring container, filled and emptied in phases to set threshold values to ascertain fuel consumption on gravimetric principle
Inventor: STRICKERT HERBERT PROF DR SC T
IPC: G01F23/14
Filed: 1990-11-20
Abstract: The base pressure in the measuring container (1) is continuously measured and supplied to an evaluating and control unit (10). The latter registers speed of change of the base pressure. The flow mass, according to the formula A/g multiplied by p, is ascertained in the phase in which the base pressure has a sinking tendency. In the phase during which the base pressure has a tendecy to rise, the formula m=mzu-A/g multiplied by p is used. A is the cross-sectional area of the measuring container, g is the acceleration due t gravity and p the speed of base pressure change. If there is a change in base pressure rate of change in the last mentioned phase, a control switch over follows in the first mentioned phase in which the actual mass of inflow, mzu, is ascertained for use in the given formula. USE/ADVANTAGE - Rapid and precise measurement during the filling phase as well as in the emptying phase of the measuring container. Large ships engines fuel supply.

Patent DE-4117994-A1 (DE)
Inventor: HUETTER INGO
IPC: H04N7/00
Filed: 1991-06-01
Abstract: Television system for the compatible transmission of letter-box signals. According to WO91/03906, signal sections in the picture image are formed before a compatible letter-box transmission within 16:9 television signals and within these signal sections the spectral position of high-frequency spectrum sections is shifted in relation to the full spectrum of the signal section concerned and other, lower spectral sections are removed from the total spectrum of the signal sections concerned and additional information is formed from these lower spectral sections which is transmitted in the peripheral strips of the letter-box format. This does theoretically make it possible to transmit the full vertical resolution for the 16:9 receiver but this process can give rise in the standard receiver to reduced vertical resolution and, with a dynamic image content, to movement artifacts. Forming the signal sections in the field and transmitting high-frequency DCT coefficients without any shift in the coefficients in the entire spectrum make it possible to avoid movement artifacts in the compatible image and attain a subjectively virtually unreduced vertical resolution. For television receivers of 4:3 image format and extended 16:9 image format.
