Title: Electronic ergometer for test object - determines work content from evaluation of output of seismic sensor attached to object
Inventor: SIDORENKO GEORGJ IVANOVIC DR
IPC: A61B5/22
Filed: 1980-11-13
Abstract: An electronic ergometer measures the work performed by a person under test and can be used for medical research, sport etc. It enables several physiological parameters to be evaluated and the assosicated data to be stored. A seismic transducer converts oscillations of the person's centre of gravity into electrical signals which are fed to a pulse shaper which controls the frequency regulation circuit of a high frequency multivbrator. The multivibrator output feeds the count input of a frequency divider whose output is connected to the count input of a multiple location counter. The divider output also feeds a second counter whose first set input is controlled by a null point circuit. A controlled clock drives the second set input and the control input of the second counter which drives the display unit changeover switch.

Title: Device for utilising ambient heat, in particular heat-exchanger roof
IPC: F24S10/75
Filed: 1981-01-26
Abstract: The device possesses a large-area heat-exchanger element, having flow paths through which flows heat-transfer medium and which run adjacent to one another, and is directly exposed to environmental influences with one side facing the surroundings. In at least one position, it possesses flow paths running next to one another for the heat-transfer medium and is arranged at a distance from a receiving surface. The space between the receiving surface and the rear side of the heat-exchanger element forms a channel through which flows ambient air and, in the interspace between the rear side of the heat-exchanger element and the receiving surface receiving the latter, additional flow paths for heat-transfer medium are arranged. In this case, the flow paths extending in the interspace between the receiving surface and the rear side of the heat-exchanger element can be pipes, which provide the spacing of the heat-exchanger element from the receiving surface and divide the interspace through which flows ambient air into channels preferably extending parallel to one another.

Title: Mounting of a metal pipe in a hole in a metal wall
Inventor: SCHWALM DIETER
IPC: F16L5/06
Filed: 1981-02-27
Abstract: Mounting of a metal pipe (1) in a hole (8) in a metal wall (7) using a clamping ring (2) which is driven into an annular gap between the pipe (1) and the hole (8), by axial pressure.

Title: Negative photographic silver halide emulsion, process for its preparation, and photographic silver halide recording material containing it
Inventor: HONDA CHIKA
IPC: G03C1/005
Filed: 1981-04-15
Abstract: A negative photographic silver halide emulsion is described whose silver halide grains contain 0.01 to 7 mol% of silver iodide and 10<-8> to 10<-5> mol of iridium ions per mol of silver halide and in which the silver iodide is in the interior and the iridium ions are present on the surface or in the vicinity thereof. Such an emulsion is prepared by combining, with stirring, an aqueous silver salt solution with an aqueous halide solution of suitable iodide content, adding to the silver salt, immediately before/after this has been added (to the halide solution), a suitable quantity of a water-soluble iridium compound and finally removing excess soluble salt from the dispersion. A silver halide emulsion as described is suitable for preparing photosensitive photographic recording materials of high sensitivity, improved pressure desensitisation properties and improved variation properties from the law of reciprocity, both at high and low intensity.

Title: Arrangement for disconnecting a circuit
Inventor: RICKEN HEINZ GUENTER
IPC: H01H85/46
Filed: 1981-05-02
Abstract: The invention relates to an arrangement for disconnecting a circuit in the case of an overload, having a tight tolerance in the disconnection current, the circuit containing a series circuit consisting of an inductor, through which an AC current flows, and a device, responding to the heat of the current, for interrupting its own circuit or another circuit in the event of a rated current being exceeded, preferably a melting fuse, a carbon layer fuse resistor, an extruded wire resistor in a safety design, a fuse which can be soldered back, a trip device by means of a bimetallic strip etc, referred to below as a "fuse" and the current intensity of this circuit being determined at least partially by the impedance of the inductor. According to the invention, the inductance is an inductor coil having a core of ferromagnetic material and a winding consisting of a wire of such resistance that the Curie point of the ferromagnetic material can be reached as a consequence of thermal coupling to the winding and its heating slightly above the rated current of the thermal fuse. In a development of the invention, the ferromagnetic coil is dimensioned (cross-section, air gap etc.,) such that it is magnetically saturated if the rated current is exceeded. The invention is advantageously used in the case of electronic apparatuses which are subject to stringent safety regulations (for example, in television sets, preferably in the horizontal deflection stage). Numerous devices are known which interrupt their own circuit or another circuit in the event of a rated current being exceeded and hence protect other components or circuit groups from destruction.

Title: Machine for folding and laying flat folding-box blanks
Inventor: KECK JUERGEN K
IPC: B31B50/06
Filed: 1981-05-13
Abstract: A machine for folding and laying flat folding-box blanks has a feed station possessing lateral guide elements by means of which the folding box blanks to be fed to the downstream folding station can be positioned transversely to the conveying direction. Moreover, the distance between the force engagement points of the conveying means of the feed station and the folding station is adjustable, so that the folding box blanks are not accelerated through the folding station until the folding box blanks leave the feed station. Both the positioning transversely to the conveying direction and the setting of the point of engagement of the conveying means of the folding station with respect to the feed station permit the feed of the folding box blanks to extend exactly parallel to the conveying direction, even when only a central conveying means is provided as a conveying means in the folding station. In this case, the lateral guide elements are set so that the lengthwise axis of this conveying means extends through the focal line of a folding box blanks to be fed. The variable design of the feed station thus permits not only adjustment to folding stations of structurally different designs but also, in particular, the use of a folding station with only one central pair of conveyor belts, which permits the building of a folding station of simpler design.
