Title: Cooling tank esp. for electron microscope specimens - is sealed against atmosphere and has vessel containing inner vessel
Inventor: UMRATH WALTER DR
IPC: F25D3/10
Filed: 1973-10-03
Abstract: The cooling system uses liquid nitrogen or liquid air for shock freezing of specimens. The cooling system is opened for inserting the specimen and for item removal. The outside cooling tank is a cylindrical vessel with suitable seal and cover plate, and the internal vessel is accessible through the opening in this coverplate. Only the annular opening between the inner and outer vessel remains closed. The inner vessel is also cylindrical and it is joined to the bottom of the outer vessel by soldering or bracing. A copper bottom is used for preventing boiling of the coolant in the inner vessel and the outside vessel is enclosed by a thermal insulation which may consist of a vacuum chamber.

Title: Arrangement for cutting pipes with slitting wheel - while pipe is mounted on rollers on a frame so that it can rotate
Inventor: HUZEL KARL
IPC: B24B27/08
Filed: 1973-10-24
Abstract: The pipe is laid on two rows of rollers which are mounted in a frame. The axes of rotation of the rollers are parallel with the axis of the pipe. The pipe is pressed against the rollers by a 'V' shaped bracket which hinges from a point on the frame. A slitting wheel with drive motor are mounted on the 'V' shaped bracket and press it against the tube. A rail with a second set of rollers is mounted under the tube. The axis of these rollers are at right angles to the axis of the tube. The rail can be lifted with a crank so that the second set of rollers lift the tube clear of the first set of rollers. This makes longitudinal positioning of the pipe possible after which it is lowered again on the first set of rollers. The slitting wheel and drive motor hinge on the 'V' bracket in such a way that the circumference of the wheel cuts the circumference of the pipe.

Title: Dynamic scanning to detect position of object edges or lines - with dynamically operating photoelectric scanning apparatus determines angular orientation of lines
Inventor: JACOBY HANS-DIETER DIPL ING DR
IPC: G01B11/00
Filed: 1974-02-02
Abstract: The scanning movement is executed by a rotating shutter with a transparent scanning spot which periodically crosses the edge or line. The phase relationship of the photo-electric signal occurring during the scan is measured in relation to the phase relationship of the scanning movement of the scanning apparatus, in order to determine the angular position of the edge or line. By evaluating the signal spectrum of the photoelectric signal, e.g. in a spectrum analyser, the position of the centre point of the scanning movement in relation to the position of the edge or line is ascertained.

Title: Adaptive filter in facsimile, TV or video telephone channel - involves reference signal for filter adjustment
Inventor: POSTL WOLFGANG DIPL ING
IPC: H04N5/14
Filed: 1974-02-11
Abstract: A test signal transmitted through the channel, is compared at the channel output with a reference signal, and generates an error signal used for the adaptive filter adjustment. The transmitted test signal is applied to a manually adjustable filter or pulse shaper, at whose output the reference signal appears. The filter or the pulse shaper is adjusted to subjective optimum picture quality. An auxiliary signal synchronised with the test signal is applied to the filter or pulse shaper. It is generated by steepening or regeneration and possibly delaying of a synchronisation pulse. The filter or pulse shaper has at least one variable component. It is a linear circuit.

Title: Fitting attached by matrix to a material layer - has punched-through webs for concealed appearance, esp. locks on suitcases
Inventor: FRANK PETER
IPC: A45C13/00
Filed: 1974-09-17
Abstract: The fitting lock which is to be fastened to a material layer, e.g. a suitcase, has fastening tongues which penetrate the material layer, with the free ends being placed round inwardly curved webs punched through a protruding part of a plate adjoining the material layer. The fitting is attached by a matrix with lugs which engage in the openings formed by the inwardly curved webs and have contact faces inclined opposite those of the plate associated with the webs. Since the webs are punched through and not out, no material is punched out of the plate and as the webs are relatively narrow the part of the fastening tongues exposed on the outside is restricted to a minimum, preventing damage or injury to surrounding objects or people.

Title: Function generator with two separate resistors - resistors replaced by single resistor chosen to give equal resistance-time ratios
Inventor: ZWACK EDUARD
IPC: G06G7/28
Filed: 1974-09-19
Abstract: The function generator has at least two of its separate resistors replaced by a single resistor. The ratio of the resistance of this single resistor and the duration for which it is effective is chosen equal to the ratios of the separate resistors (that have been replaced by the single resistor) and the duration for which these resistors are switched in by the control circuitry. If the time sections are subdivided then the single resistor is switched such that the voltage left on the capacitor is equal to the voltage that must be applied to the separate resistors at the end of a given time.

Title: Light intensity controller for indoor photography - with variable potentiometer added to camera hand grip
Inventor: SUEMENICH SIDO
IPC: G03B15/03
Filed: 1974-12-21
Abstract: To control the increase in light intensity when filming by artificial light, this device adds a spring loaded light control release (3) to the camera hand grip next to, but extending further out than the shutter release (4).

Title: Straight tube water preheater - has shell with straight tubes fitted within the tubed shell of the main body
Inventor: HIEKE JUERGEN
IPC: F28F9/02
Filed: 1975-02-10
Abstract: Two-stage water preheater for steam turbines has increased capacity without increasing the size. The shell contains top and bottom tube plates fixed rigidly to the shell and a number of straight tubes between the plates. A second, smaller shell of similar arrangement is fitted within the main shell, containing a number of straight tubes anchored in a tube plate.
