Patent DE-4107853-A1 (DE)
Inventor: KUHN JENS DR ING
IPC: G01K13/00
Filed: 1991-03-12
Abstract: It is difficult to disinfect and recalibrate prior art medical thermometers and to protect their battery and switch contacts from corrosion. Their clinical use therefore poses problems. The new thermometer combines the advantages of the electronic medical thermometer with those of a conventional mercury-in-glass thermometer. The electronic medical thermometer consists of a circuit known per se and other passive components (8) and an indicator (4), which are housed in a hermetically sealed glass sheath (3). Like conventional mercury-in-glass thermometers, the electronic thermometer is actuated by a shaking movement. For the purpose of legally prescribed calibration and recalibration, the electronic medical thermometer can be compensated, without having to be disassembled, by a laser compensating resistor (7). Because of its structure, this thermometer is particularly suitable for temperature measurement in human medicine.

Title: Injection method of underground mineral extraction - using drill string with injection head used as drill bit, and flushing up loosened material from deposit to top of drill string
Inventor: KLEMM GUENTER W PROF DR
IPC: E21B43/29
Filed: 1991-06-28
Abstract: The method inserts a drill string (15), fitted with an injection head (16), down to the required depth. Then it rotates the injection head and ejects jets from it, with simultaneous flushing back of the material, thus loosened, through the drill string and leaving a cavity in the ground. Axial movement of the injection head is carried out in previous step over the whole required excavation depth without admitting filling material. Then flushed-back material is removed at the top end of the drill string and the cavity (21) filled with filling material. A device is included to stabilise the ground by freezing, providing the drill string with suction and with compressed air. USE/ADVANTAGE - For extracting minerals (such as uranium and manganese)from large depths. Uses simple means and excludes impurities.

Title: Double radial tyre - has double construction with inner annular tube touching rim but not tread and inflated to higher pressure than outer body
Inventor: ASANO KAZUO
IPC: B60C17/01
Filed: 1991-11-29
Abstract: The tyre basically has two radial sidewalls from the ends of the tread with beads at their radially inner ends mounted on a rim. The structure has an integral inner ring held at a higher inflated pressure than the main body of the tyre. The product consists of the tread (2), the two sidewalls, (3) with the beads (4) at their ends, and the rim (9), the carcass (6) passing round so as to reinforce the sidewalls (3) and wrap round the bead cores (8). The tyre also has a belt (7). Inside the tyre is the annular member (10) which is generally concentric with the tyre and is kept at a higher pressure than the tyre itself. The radial height (h) of the member (10) is between 1/3 and 3/4 the height (H) of the whole tyre when inflated to normal pressure and not under load. Consequently the inner face of the tread (2) does not meet the inner member (1) when not under load. When the assembly is not loaded, the main tyre (1) is at a normal (e.g.) 2.0 bar pressure. The inner member (1) is basically made up to (e.g.) aromatic cords in cross-spiral strips with a number of unidirectional cords in a belt of the same material. ADVANTAGE - The complete tyre has e.g. the same longitudinal resilience constant as conventional tyres within the low loading range (in which it is only subjected to small impact loads). It has however a higher capacity to absorb energy at high deformation loads i.e. a greater longitudinal resilience constant in the medium to high load range (where it is subjected to greater impact loads).

Title: Light sensitive smoke detector for building or house - increases triggering threshold when ambient light is present using series resistors and light-sensitive element
Inventor: CONFORTI FRED J
IPC: G08B17/10
Filed: 1991-12-06
Abstract: The light sensitive smoke detector has a base element on which a sensor is mounted (14) for detecting an ambient condition and producing a correspondence output signal (VCNET). A threshold generator (R1,R2,R3) produces an electrical output signal (VREF) correspondence to the generated threshold value. A radiation sensitive element (18) e.g. a semiconductor with variable resistance is connected to the threshold generator to vary the threshold according to the incident radiation energy. The electrical output signal of the sensor is compared (CA) with the threshold value. USE/ADVANTAGE - For detecting smoke or combustion products in the home. Eliminates false alarms during the day caused by kitchen smoke and similar and provides very high level of safety during the night.

Patent DE-4208521-A1 (DE)
Title: Inhalation anaesthetics recovery - dries the gas mixture for active carbon adsorption and catalyst to release nitrogen and oxygen into atmosphere and remainder cooled to a fluid for storage or disposal
Inventor: MANEGOLD CHRISTOPH DIPL ING
IPC: B01J20/34
Filed: 1992-03-17
Abstract: To separate and recover the components of inhalation anaesthetics, the mixt. is initially dried to remove water vapour and then passed through a filter with active C or similar material for the adsorption of the anaesthetic components apart from the N2O. Any remaining vapours are passed to a catalyst to break down the gas and release N2 and O2 into the atmosphere. The adsorbed material is released from the filter by heat and then restored to a fluid form by cooling to be retained within a container. Pref. before shipment for further processing, the recovered fluids are passed through a water sepn. stage. A dryer with zeolithic material is used to dry the gas mixt. After drying, the gas mixt. is passed through an initial active C stage or otherwise neutralised to prevent unplanned chemical reactions. The active C filter is held at a low temp., pref. about 5 deg.C. To give a continuous processing action, all or some of the stages are duplicated at least so that some stages are in action while the other are in the early stages, for the material to follow a clear path through the system by using available stages. Heat is also delivered by the active C filter(s) for the catalyst, the regeneration of the zeolithic material at the dryer and/or desorption of the inhalation anaesthetics. N2 is used to cool the dssorbed anaesthetics and also to cool the active C filter for adsorption. The drying of the gas mixt., the cooling of the active C filter and its desorption and/or the conversion of the anaesthetics into a liq. are at least in one section, with a recirculating coolant in a closed circuit with a heat pump. USE/ADVANTAGE - For the treatment of gases used for inhalation anaesthetics. The components are sepd. easily, and the recovered material can either be returned to the supplier for reprocessing or disposed of
Patent DE-4208552-A1 (DE)
Inventor: LIEDTKE RAINER K DR
IPC: A61K47/14
Filed: 1992-03-17
Abstract: To improve and promote wound healing and cell regeneration, topical insulin preparations are produced and contain insulin which is in concentrations which are pharmacologically effective for local applications and which is in preparations pharmaceutically suitable for topical applications, preferably emulsion or suspension, cream, ointment, gel or a plaster system. To increase the efficacy of the topical forms they can contain as additional ingredients substrates such as simple sugars, cofactors such as electrolytes, peptides other than insulin, protease inhibitors and antioxidants to prevent inactivation and degradation. The lipid phases used in emulsions are preferably physicochemically and toxicologically suitable mixtures of partial glycerides of chain length C6-C18. It is possible to use vehicles with particular adhesiveness for wounds for internal topical applications. The topical insulin preparations are physiologically adjusted, pharmaceutically specified topical systems for wound healing and cell regeneration with biochemically intensified local activity. They extend the current possibilities for the therapy of wound healings and cell regenerations which are slowed down metabolically, physically or due to perfusion.
