Title: MOvement detecting cot support for infant - warns of sudden infant death and has vibration dampers excluding external influences
Inventor: NASER GEORG ING GRAD
IPC: G01G19/44
Filed: 1980-12-29
Abstract: The Parent Patent describes a cot support for an infant equipped with force signal transmitters and processing equipment enabling the signals to be monitored for an early warning of danger of a sudden infant death (SID Syndrome). The cot support contains damping elements for suppressing external vibrations not caused by movements of the patient etc. In the Patent of Additon, each damping element (2) is composed of a foam plastics object (34) and a surrounding elastomer sleeve (30) encompassing a volume larger than that of the foam and enclosing also an air cushion. Preferred plastics foam for the object (34) is polyester-urethane or polyether-urethane, esp. of density less than 0.3 g/cm3. This arrangement comprises a combination of two previous damping systems, namely air cushion and foam, and has the advantage that vibrations of less than 5Hz can also be suppressed. The foam block (34) is pref. disc-shaped, more specifically circular, square or rectangular or polygonal in plan. The encompassing sleeve (30) may be of synthetic or natural rubber.

Title: Heating system
Inventor: BLOMQVIST LEIF ERIK GUSTAF
IPC: F23K5/20
Filed: 1981-02-16
Abstract: A heating system for buildings comprises a tank (1), a heating boiler (8) with burner (6) and heating elements (radiators). Taking the viscosity of the oil into account, the burner (6) is operated discontinuously. The interruption intervals constitute the trigger for cooling effects. The present invention shortens the length of the intervals in that the oil is heated to a temperature up to the flash point of the same and in that the opening width of the nozzle (7) of the burner (6) is reduced to a width which is adapted to the viscosity of the heated oil. <IMAGE>

Title: Method and device for rapid measurement of local velocity components in a velocity field
Inventor: LEHMANN BERNHARD DIPL ING
IPC: G01P5/26
Filed: 1981-02-19
Abstract: Despite a large number of various types of measurement techniques, it still remains a problem today in hydrodynamics to obtain experimentally an exact overall picture of the local velocity components in a flow field over an extended flow cross-section. The flow velocities are to be detected locally in terms of their components or vectorially and in a quasi-instantaneous manner. For this purpose, an optical beam, for example a bundle of laser light, is optically scattered in the velocity field of scattered particles (2) which are being carried along, and the light track (3) thereby generally visible is optically scanned by a receiving device and the received scattered light is herded to a Smeet laser-Doppler spectrometer, which analyses with sufficient rapidity the instantaneous Doppler shift of the wavelength of the scattered light with respect to the original light, and in the process, for example in a stepwise fashion and locally along the light track (3), instantaneously detects the magnitude and sense of direction of the velocity components respectively present. The direction is yielded by means of an additional position measurement of the measuring point from the instantaneous geometry, thereby known, of the optical arrangement. <IMAGE>

Title: Recording format suitable for a cue review and arrangements for recording and replaying this format
Inventor: REITMEIER GLENN ARTHUR
IPC: H04N9/808
Filed: 1981-03-02
Abstract: In a recording and replay system for colour images, the colour image quality for replay in cue review is improved by the video signal for each frame or field, scanned at a predetermined multiple of the colour subcarrier frequency, is recorded divided over a number of tracks, only some of the recorded information being selected for reconstruction of the image to be replayed in cue review mode. In detail, only pixel groups which in each case correspond to a whole colour subcarrier period (1-4, 5-8, 9-12 etc) are recorded on the tracks (1, 2 or 3) in such a manner that a video signal can be easily reconstructed from these with the correct colour information during the cue review mode. In a preferred embodiment, successive pixel groups are recorded on separate tracks, the pixel groups which are to be replayed during the cue review mode all being placed on a single track. Thus, these pixel groups on the single track can be in each case repeated several times in order to obtain instantaneous coherent information for reconstructing the cue review image. <IMAGE>
Patent DE-3113314-A1 (DE)
Title: Heating and ventilating system
Inventor: BORBELY GYOERGY DIPL ING
IPC: F24D5/00
Filed: 1981-04-02
Abstract: The heating and ventilating system has a drying chamber (19), in which laundry can be hung up. The moist outgoing air leaving the drying chamber (19) is supplied to a heat exchanger (35) where it yields a part of its heat to fresh air which likewise flows through the heat exchanger (35) in separate branches (15, 16) and is thus preheated. The outgoing air is carried off by an outgoing-air pipe (18) after leaving the heat exchanger (35). A part of the preheated fresh air passes either directly into the drying chamber (19) or after passing through a heating device (58). Another part of the preheated fresh air, which is possibly further heated by the heating device (58), is conducted via a hot-air duct (60) into the room and used for heating purposes. A further heating body (64) is connected to an inlet opening (65) and an outlet opening (67) of a cavity (61) of a double bottom so that in addition a closed circulation system for an indirect floor-heating system operated with hot air is formed.   <IMAGE>

Patent DE-3124439-A1 (DE)
Title: Lift valve with flexible sealing diaphragm
Inventor: KEMMERLE DIETER DIPL ING
IPC: F16K5/20
Filed: 1981-06-22
Abstract: A lift valve with an elastically deformable sealing diaphragm (24) which, under pressure, comes to rest against a valve seat (4). The valve plate (21) is connected to the housing (3) by spring elements and closes a first pressure space (23), to which fluid can be admitted, initially at a relatively low pressure P1, via a conduit (14). Between the valve plate (21) and the diaphragm (24) there is a second pressure space (26). The pressure P1 is sufficient to move the valve plate (21) into the closed position. A higher pressure P2 is then applied. At this pressure, the non-return valve (30) opens and pressure is admitted via a first conduit (28) to the second pressure space (26). The sealing diaphragm (24), which is provided with a fold (25) to allow greater expansion, continues to rest against the valve seat (4) until the pressure in the first pressure space (23) is reduced. The second non-return valve (31), which opens at a comparatively low differential pressure allows relief of the second pressure space (26) via a second conduit (29) into the first pressure space (23). The valve is particularly suitable for use in large fittings in pipes carrying liquid metal, e.g. in nuclear power stations. <IMAGE>

Title: Method of calibrating, for measurement purposes, gas semiconductors which are tested or readjusted automatically at certain time intervals by means of calibration devices
Inventor: FUHRMANN HANS DR
IPC: G01N27/12
Filed: 1981-07-07
Abstract: The method and the device designed to carry it out are intended to simplify the calibration of gas semiconductors for measurement purposes and to improve the measurement accuracy. Instead of a regular injection of calibration gas, for the purpose of a calibration-gas injection to be initiated at longer time intervals, at least one substitution resistor is connected in parallel with the gas semiconductor via a relay during the zero-point phase. The substitution resistor corresponds to the differential resistance between the zero point and a known gas concentration within the measurement range and consequently simulates the measured value of the gas concentration. <IMAGE>

Title: Pressure sensor (pick-up, transmitter, transducer), in particular for a motor vehicle
Inventor: BALCKE GERHARD ING GRAD
IPC: G01L9/00
Filed: 1981-08-12
Abstract: A pressure sensor is proposed for detecting a pressure, in particular the induction (intake) pressure of an internal-combustion engine, in which there is provided a diaphragm or syphon diaphragm which is exposed to the pressure and whose centre moves as a function of pressure and in so doing changes the distance between a permanent magnet and a Hall IC arranged opposite thereto. In order to achieve a linear sensor characteristic and a compact sensor structure, in this case use is made of a Hall IC having a linear dependency between the IC output voltage and the magnetic induction, and the Hall IC and the permanent magnet are arranged to have the same axis relative to one another. The permanent magnet preferably consists in this arrangement of a cobalt/rare-earth compound. <IMAGE>

Title: Method and appliance for measuring the flow rate of individual components of a fluid mixture
Inventor: IBARAKI YOSHITAKA
IPC: G01F23/72
Filed: 1981-09-16
Abstract: The method for measuring the flow rate of individual components of a fluid mixture of gaseous and liquid fluids is carried out in such a way that first of all the components of the fluid mixture are separated and the flow rate of the liquid is determined in such a way that the separated liquid is passed into a graduated cylinder (10), in which the flow rate through orifices (11) formed in the graduated cylinder (10) is interrelated with the liquid level in the graduated cylinder (10), and the flow rate of the liquid is measured by observing the liquid level. The corresponding appliance has a graduated cylinder (10) which communicates with a gas-liquid separating chamber (2) and has orifices (11) and a liquid-level measuring device (12, 13, 14). <IMAGE>
Patent DE-3142276-A1 (DE)
Title: Device installed in a concrete slab for carrying away moisture
Inventor: HONEGGER HEINZ
IPC: E01D19/08
Filed: 1981-10-24
Abstract: Devices for carrying away moisture which forms between a concrete slab (B) and an insulating layer (I) and penetrates through a covering (S) applied to the insulating layer tend to become blocked due to furring. Long, dangerous icicles often form in winter on the outlet connection piece. The device which prevents this has a discharge pipe (20) which passes through the concrete (B) and in which a funnel (30) is inserted. The outlet pipe (33) of the funnel is distanced from the discharge pipe (20) by means of a centering collar (32). The discharge pipe (20) opens out at the lower end into an outlet connection piece (10) having two draining-off collars (11, 12). An extension pipe (50) which opens out into a collecting pipe (51) can be connected to the outlet connection piece (10). The collecting pipe (51) is accessible by way of a cleaning connection piece (52). The water seeping through the covering (S) is carried away by means of a mushroom-shaped insert (40) which is supported in the outlet pipe (33) of the funnel (30) by ribs (42) arranged on the stem. The device is particularly suited to installation in bridges. <IMAGE>

Patent DE-3150257-A1 (DE)
Title: Image intensifier
Inventor: ROEHRICH HEINZ
IPC: H01J31/50
Filed: 1981-12-18
Abstract: The invention relates to an image intensifier having a vacuum bulb (1) which contains, one behind the other, a photocathode (6) and electron multiplier stage (10) consisting of a plurality of grids which are coated in an insulating manner and are connected one behind the other, and having an output fluorescent screen (8) which is connected to an electrically conducted anode layer (9). It has been found to be unfavourable in such image intensifiers that, even with precise alignment and fixed mounting on the edge, the individual grids (11) can start to oscillate, especially in the case of relatively large surfaces, for example in the case of a shock, resulting in interference in the imaging. To prevent this disadvantage, the invention provides for the grids (11) which are coated (12) in an insulating manner to be arranged in layers directly one on top of the other, so that a compact grid stack is produced as the multiplier (10). An image intensifier equipped according to the invention is especially suitable for use in medical X-ray diagnosis. <IMAGE>

Title: Stirrer
IPC: B01F15/06
Filed: 1982-01-07
Abstract: The invention relates to a stirrer for the mechanical and/or thermal treatment of, in particular, media which do not flow readily, such as, for example, supply materials in a container. For this purpose, a rotor shaft (1) fitted with blades (F) projects from a drive motor (2). The rotor shaft (1) and the screw blades (F) are provided with an internal duct and chamber system which is connected via a distributor in the region of the rotor-shaft bearings to a circuit (9) with an exchanger (10). The liquid heat transfer medium passes through the stirrer elements, allowing the desired temperature to be established rapidly and in an effective manner while treating the materials gently. <IMAGE>
Patent DE-3205272-A1 (DE)
Title: Clamping connection for channel section segments
Inventor: HEINTZMANN PETER DIPL ING
IPC: E21D11/22
Filed: 1982-02-15
Abstract: The known clamping connections have stirrup straps which, in such a way as to be adapted to the contours, overlap the end sections of the channel section segments, which end sections are laid one inside the other in an overlapping manner. The stirrup straps are tightened against one another by bolts with nuts arranged at the side of the section flanges and the channel section segments are thereby braced against one another via their flanges. In order to be carried along during relative movements of the channel section segments, the straps have projections which come to bear on the end faces of the channel section segments. Disadvantageous here is the arrangement of the clamping straps between the rock and the channel section segments. This results in the risk of collision. Furthermore, a considerable amount of material is required, since the stirrup straps are accurately adapted to the contours of the channel sections. When used on W-shaped channel section segments (3, 4), clamping straps (15, 21) are now only attached in the area of the profile flanges (7, 8) with spacing elements (16) inbetween. The spacing elements (16) enclose the bolts (19). This reduces the tensile stresses while maintaining the pretension. The clamping straps (15, 21) are in a favourable assembly position in the area on the roadway side. Collisions with the rock (73) are avoided. The clamping connections (12) only perform the function of absorbing transverse forces and holding the channel section segments (3, 4) together. The push-in resistance is now determined by screw clamps at the end faces of the channel section segments (3, 4). <IMAGE>
Patent DE-3212176-A1 (DE)
Title: Web-guide device
Inventor: ZERLE LUDWIG DIPL ING
IPC: B65H23/02
Filed: 1982-04-01
Abstract: The invention relates to a device for guiding a running web in a desired running direction. At least one guide roller arranged in a web loop is driven in run-correcting pivoting movements about an axis essentially vertical to the running direction of the web and intersecting the web plane perpendicularly. Known devices of this type either have a sluggish responsiveness or tend to obtain an oscillating regulation of the web run. The object is to provide a device of this type, in which the correcting effect of the guide roller is improved in terms of a sensitive response and oscillating regulation is avoided. This is achieved, according to the invention, in that an independently driven spreading roller bears with prestress on the surface of the web at a short distance in front of or behind the guide roller in the running direction of the web, the axis of rotation of the spreading roller being parallel to the axis of rotation of the guide roller only in the basic position of the latter.
