Title: Thermal conductivity detector in gas analyser - is preceded by heat exchanger to stabilise temp. of incoming gas to that of detector casing
Inventor: BOPST JOACHIM DIPL ING
IPC: G01N27/18
Filed: 1980-12-17
Abstract: A measuring device for gas analysis equipment used in the determination of thermal conductivity of gases comprises a detector unit (11) containing a measuring sensor bore (12), measuring sensor (13) and gas inlet and outlet ducts (18,19). The entire casing of the detector block is thermostatically heated and externally insulated. Upstream of the detector block (11) the gas inlet duct (18) passes through a heat exchanger (22) which is maintained at the same temperature as the detector block casing itself. Pref. this heat exchanger is in good thermally conducting contact with the heated casing of the detector block. The heat exchanger may comprise a helical tube (23) in good thermal contact with a hollow cylindrical core (notshown). This core is in good thermal conduct with the detector casing. . Used as a measuring device in gas chromatography where the compsn. may be determined from the thermal conductivity. The result of the readings is affected not merely by the compsn. however, but also by the flow velocity of the gas and its inlet temperature. Previous devices have partly overcome this problem but suffer from fluctuation inlet temp. of the gas leading to unstable conditions. By incorporating a heat exchanger upstream of the detector, the inlet gas is already brought to the temperature of the detector casing. Consequently the stability of the device is improved and its sensitivity is increased while at the same time constants are reduced.

Title: Intravenous liquid administration by pump - with external pressure sensing cartridge regulating discharge pressure
Inventor: JENKINS JON A
IPC: G05D16/06
Filed: 1980-12-19
Abstract: A pump for delivering an intravenous liquid to a patient includes an integral sensor for detecting the pressure of the outlet stream. The outlet passes through a disposable cartridge which has a diaphragm responsive to the liquid pressure. This cartridge is retained by detents within a cavity in the pump housing so that the diaphragm movement activates a plunger rod. The plunger rod is spring-loaded and operates a pivoted lever. When the pressure in the cartridge exceeds a predetermined value the lever causes a light beam to be broken. This stops the pump until the normal operating pressure is attained. The apparatus delivers an intravenous liquid at a controlled pressure.

Title: Switching drive for high-voltage circuit breakers
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/14
Filed: 1981-01-23
Abstract: In the case of high-voltage circuit breakers having multiple interruption - that is to say there are two or more switching units on one switch pole - one of the important factors is to supply the drive force of the circuit breaker main drive to the individual switching units via a drive which is designed as economically as possible. Although a certain level has already been reached in this field, there are still significant improvement possibilities. The following items summarise how these improvements have essentially been implemented: integration of the drive levers to form a compact drive body with a switching-force drive and two or more switching-force output drives. Reduction in the number of supports of the drive levers to a single shaft for the drive body according to the invention. Universal applicability of the mechanically and dielectrically advantageous principle of parallel output drive of the switching forces to the individual switching units as a direct consequence of the improvements mentioned above.

Title: Heat sink for cooling spark plugs or ignition chambers of internal-combustion engines
Inventor: LATSCH REINHARD DIPL ING DR
IPC: H01T13/16
Filed: 1981-03-03
Abstract: A heat sink (3) (heat-dissipating body) for installation in the cylinder head (2) of an internal-combustion engine is described, which accommodates either a spark plug or an ignition chamber or an ignition chamber spark plug (14). The heat sink (3) has a heat transmitting device between the cylinder head (2) and the ignition chamber spark plug (14), which heat transmitting device has a thermal conductance whose magnitude varies as a function of the temperature of the heat transmitting device. The change is effected such that the quantity of heat dissipated from the ignition chamber spark plug (14) to the cylinder head (2) is considerably increased above a specific temperature or temperature region. The heat transmitting device can be constructed as a so-called heat tube. When the internal-combustion engine is started, the heat sink (3) makes possible a rapid rise in the temperature of the ignition chamber spark plug (14) up to its operating temperature, which is kept constant within a narrow range. The heat sink remains in the internal-combustion engine during testing and replacement of the ignition chamber spark plug. <IMAGE>

Title: Ear protection
Inventor: GORMAN ANTHONY GRAHAM
IPC: A61F11/08
Filed: 1981-05-14
Abstract: There is proposed an ear protection enclosing an air volume and comprising an ear shell (20), an ear pad (21) and a diaphragm (22) inserted in an opening (23). The rigidity and mass of the diaphragm (22) are determined in such a way that the attenuation frequency response of the ear protection is level from low frequencies (200 Hz or less) to the frequencies important for understanding of speech (at least 2 kHz). Instead of the diaphragm or additionally to it, it is possible to use other designs for flattening the frequency response e.g. other diaphragms and intermediate walls with connecting tubes which subdivide the volume enclosed in the ear shell. The invention can also be applied to an ear plug. <IMAGE>

Title: Copying apparatus for textile patterns
Inventor: BRUENE BERNHARD DIPL ING
IPC: D05C17/00
Filed: 1981-05-16
Abstract: Canvas and canvas-like basic materials are used as a base and pattern especially for hand-knotted carpets. They are stretchable, thus making it difficult for patterns to be copied on. By means of one and the same appliance, textile patterns are received from a master by means of a copying apparatus and subsequently applied to the canvas web by the same appliance, if appropriate after very little conversion work, a plotter-like system for the detection and reproduction of patterns being arranged between a tension roller tensioning the canvas web and a braking roller. This system is assigned a data-processing part and a measuring device monitoring the material run. The measuring device consists of a part measuring the longitudinal co-ordinate values and a part measuring the transverse co-ordinate values. The latter has a supporting frame and optoelectronic sensing and nozzle arrangements movable thereon. Via the measuring device and the sensing device, the co-ordinates and colour of each individual spot are first determined and are then stored, and subsequently during reproduction, when the corresponding spot on the canvas web is reached, the nozzle is opened and the corresponding dye sprayed on. Use is made of electronic colour sensors which can recognise at least 24 different colours and, on the other hand, of nozzle blocks with a corresponding number of combined nozzles and dye stores. A copying apparatus of this type works with pinpoint accuracy, so that pattern masters can thereby be prepared or carpet webs or the like processed quickly and accurately. <IMAGE>
