Title: Intra-oral probe
Inventor: TIETZ ERICH
IPC: G01K13/00
Filed: 1981-04-04
Abstract: The invention relates to an intra-oral probe for detecting inflammable and/or degenerative process in odontology and in ear, nose and throat practice on the basis of thermal measurement data, having limitation of the contact pressure in order to avoid pressure irritations at the measurement points, and consists of a tubular body (7, 8) having a sensor tip (1) with a temperature-dependent resistor. The probe, which is partially surrounded by a protective tube (16), carries on its upper end a pressure-limiting device (3) in which the probe is resiliently mounted, in order to avoid pressure irritation at the measuring point in the oral mucous membrane. The punctiform measuring probe can be used to determine and detect incipient pathological processes, which still cannot be detected by X-ray, in the oral mucous membrane of the chewing system or of the jawbone with the aid of very fine thermometric measurements. <IMAGE>

Title: Dice-shaped learning means for combination theory
Inventor: HINZ KLAUS
IPC: G09B19/02
Filed: 1981-04-29
Abstract: A dice-shaped learning means for combination theory consists of a large number of small dice arranged at the surface of this dice-shaped learning means, subdividing the learning means into a plurality of flat layers parallel to the edges of the learning means. The individual flat layers of small dice can each be rotated about the axes of the dice-shaped learning means which pass through those layers. In such a learning means, the object to be achieved is to design the surfaces of the small dice of this dice-shaped learning element in such a manner that users can use it to check the combinational state of the learning means which has been reached without peering and inspection, so that even blind people can use this dice-shaped learning means. The invention achieves this object in that the lateral surfaces of the small dice have different surface compositions, rough surfaces and/or smooth surfaces and/or heat conductive surfaces and/or heat-insulating surfaces and/or surfaces provided with notches parallel to the edges and/or surfaces provided with diagonal notches and/or vibrating surfaces and/or electrically conducting surfaces and/or electrically non-conducting surfaces. Such a dice-shaped learning element can be used at increased speed because the user, when twisting the individual flat layers relative to each other during the very short operation of rotation, feels whether the surface of the small dice is rough or smooth, heat-conducting or heat-insulating, with or without notches, with or without a vibrating surface or electrically conductive surface.

Title: Machine for constructing, scraping and smoothing canal profiles underwater
Inventor: FAERBER KURT
IPC: E02F5/00
Filed: 1981-05-15
Abstract: The bottom of canals or at least sections of the canal bottom are often provided with a fixing and sealing layer which has to be applied underwater as plastic mortar to the canal bottom. So that this difficult work can be carried out, a machine is proposed which is essentially designed as an excavator, preferably as a telescopic excavator and is additionally equipped with a cutting and smoothing shield. Thus the mortar can first of all be applied to the canal bottom and can then be scraped and smoothed with a single machine. Adherence to the specified thickness of the mortar layer to be applied is preferably ensured by vertically adjustable supporting members on the arm carrying the cutting and smoothing shield, for example rollers or skids. <IMAGE>

Patent DE-3134890-A1 (DE)
Title: Axial compass
Inventor: PELKA HANS-JOACHIM
IPC: B43L9/00
Filed: 1981-09-03
Abstract: The field of application of the axial compass extends over technical design offices in mechanical and plant engineering. A problem in the scale drawing of circles and segments of circles (pipe bends) is the constant changing of known aids such as compass, ruler and protractor. The invention of the axial compass, combining these three instruments into a single unit, is in principle a hand-operated rotating spindle. As a result of displaceable locking possibilities for the pencil, as shown in Sheet 1 of the attached drawing, it is possible to draw circles of various diameters. In this arrangement, the planetary gear makes it possible to draw a complete circle (360 DEG ) although the propelling hand needs to execute only a half-rotation. Since the two ends of the drawing spindle move over a fixed angle scale, it is thus possible to read off the angle to be drawn and use the drawing spindle itself as a ruler for this. <IMAGE>

Title: Device for the leakage-free and force-fitting connection of a corrugated hose
Inventor: SCHWENK HEINZ
IPC: F16L11/15
Filed: 1981-11-26
Abstract: In hoses in which the internal layer consists of corrugated material, primarily PTFE, thermoplastics or metal, until now the connection of the hose fitting could be achieved only by compression. A screw configuration resulted in torsion and premature leakage. The device according to the invention, in the form of a 4-piece hose fitting, uses the geometry and pitch, especially also in the case of the double threads which occur, with an offset pitch, and achieves a force-fitting, leakage-free connection, without torsion and twisting, even for relatively high pressures. The individual parts and the shape of the connection are shown in Fig. 3. Such hose lines, and hence also these fittings, are used in the field of fluid technology.   <IMAGE>

Title: Absorbent cushion for hygienic cellulose articles
Inventor: STARY CHRISTOF
IPC: A61F13/15
Filed: 1982-02-19
Abstract: Children's nappies, napkins for incontinent individuals, patients' undersheets and similar articles contain absorbent cushions made of cellulose. These absorbent cushions have a liquid-permeable film which faces the body in use, a liquid-impermeable film which faces away from the body in use and at least one absorbent layer located between these films. However, since the liquid to be absorbed usually only emerges at a locally restricted site it must be distributed over the surface of the absorbent cushion by appropriate measures. For this it is proposed that the two covering films reach through perforations in the absorbent layer and be connected with each other. The perforations may be oblong and arranged in the longitudinal direction of the absorbent cushion. Furthermore, in each case at least one linear perforation or several discrete perforations which together form a row may be arranged in the two longitudinal edge regions. <IMAGE>

Patent DE-3212250-A1 (DE)
Title: Device for heating baked goods or dough goods
Inventor: POSSELT RUDOLF GERD
IPC: A21C13/00
Filed: 1982-04-02
Abstract: In a closed housing (10), a fermenting-climate chamber (22) is formed, which serves for heating chilled or deep-frozen baked dough goods. A heat exchanger (28), a blower (32) and an air distribution wall (18) ensure circulating-air operation. The heat-supply regulation is controlled by two temperature sensors (36, 38), the first sensor (36) measuring the circulating-air temperature and the second sensor (38) measuring the surface temperature of the product (26) to be heated or a mass simulating this. A regulating circuit ensures that the temperature difference of these two sensors keeps to a given value of e.g. 5 DEG C. The heating is switched off as soon as this temperature difference is exceeded and switched on again when it is fallen below. This regulating principle leads to a higher-quality baked product and avoids additional regulation depending upon the product quantity and moisture regulation depending upon the temperature difference between hot air and product surface. <IMAGE>

Title: Actuator for changing electric tools from the operating state "drilling" to the operating state "hammer drilling or percussion drilling" and vice versa
Inventor: GEIS WILHELM DIPL ING
IPC: B23B45/16
Filed: 1982-04-14
Abstract: An actuator for changing electric tools from the operating state "drilling" to the operating state "hammer drilling" or "percussion drilling" and vice versa is to be combined with a safety element in such a way that assembly of the actuator with the safety element is simplified and the expenditure for these parts is reduced to a minimum. This is done according to the invention by the control handle being combined with a flexible safety element containing segments having at least one undercut at their outer periphery. The end faces of the safety element which are obtained by the undercuts, after insertion of the control handle into the receptacle provided in the tool housing, come to bear against the inside of the housing wall and thus secure the control handle against being pulled out.

Title: Gastight prefabricated elements for flue-gas outlets
Inventor: GLADITZ HEINZ
IPC: E04F17/02
Filed: 1982-05-27
Abstract: Gastight prefabricated elements for flue-gas outlets in industrial construction in the fields of housing, commerce and industry are prefabricated elements corresponding to the high-production industrial prefabricated building method of the building industry. In this case, the static and physical-chemical functions are assigned to different materials. The flue-gas or waste-gas outlets are made, in an ideal cross-section, with a smooth inner surface and of a heat-resistant, acid-proof, soot-proof and gastight material. The enveloping structure performs the static functions of a chimney and provides the inner layer with protection against external influences during prefabrication, transportation, erection and space utilisation. A separating agent introduced between both materials ensures the chemical resistance and the slidability of the flue-gas or waste-gas outlets. Profiling the top and bottom parts of the elements permits positive assembly.

Title: Device for reading knitting marks, particularly bar codes
Inventor: WEBER RUDOLF
IPC: G06K7/10
Filed: 1982-05-29
Abstract: The proposed device for reading code bars (10) of a code combination (1) has for each of the code bars of a combination one display element (40), which consists of two parallel-connected light-emitting diodes, particularly a green light-emitting diode (41) and a red light-emitting diode (42), a transistor (43) driven by the level of the analog read-signal pulse (21) being connected in series with the green light-emitting diode (41) so that the forward resistance is small and the display current flows mainly via the green light-emitting diode (41) when the read code bar has good contrast, whereas with a weak contrast and correspondingly low drive to the transistor (43), the display current flows mainly via the red light-emitting diode (42). In this manner, the display changes from green to red when the contrast of the viewed code bar becomes weaker, which can be considered as a warning signal and indication of beginning unreliability of the scanning. <IMAGE>

Title: Method and device for generating electrical discharges, especially for electrical discharge lamps
Inventor: IMRIS PAVEL DR
IPC: H01J61/72
Filed: 1982-06-04
Abstract: The invention relates to a method and a device for generating electrical discharges, especially for electrical discharge lamps. Discharge electrodes which can be connected to a DC or AC voltage are provided in a medium which can be ionised. In order to increase the electron density and the number of charged particles in the electrical discharge, in order to improve the light yield, separate, monopolar columns of charged particles, which reduce the discharge path, are formed in the region of at least one discharge electrode. In this case, the discharge electrodes are arranged in a dielectric in such a manner that a space for the construction of the columns remains at least above one discharge electrode. In consequence, a plasma capacitor is formed, in which plasma forms at least one of the capacitor plates, instead of the metal plates of normal capacitors. The discharge takes place between the columns and the adjacent columns and between mutually adjacent columns and metal electrodes. The discharge in the plasma capacitor has a greater electron density, as a result of which an efficiency can be achieved when the invention is used in fluorescent lamps that is 50 to 33% better than with conventional lamps. <IMAGE>
