Title: Vacuum cleaner for floors and carpets - is fitted with water spray and has water reservoir between walls of jacketed housing
Inventor: STETTNER GERHARD ING GRAD
IPC: A47L11/30
Filed: 1980-06-07
Abstract: The vacuum cleaner fitted with a water spray (15) has a double-wall housing (1). The inner housing (2) is fitted with a container (3) to collect the dust and dirty water delivered by the suction pipe (6). A fan (11) sucks air out of the inner housing through the filter (20) and a float valve (19). The dust and dirty water remain inside the collector. When the collector is filled with water to the maximum level, the ball of the float valve shuts off a duct (21) leading to the fan. The clean water reservoir (13) is formed by the space between the inner and outer walls of the housing. This design of double wall increases the rigidity of the housing and also acts as a sound barrier to reduce the noise from the cleaner.

Patent DE-3027272-A1 (DE)
Title: TV tube frame pattern generator - combines blanking signal obtained by non-additive mixing with gating signals for two line frame
Inventor: KIRCHNER CARL
IPC: G09G5/28
Filed: 1980-07-18
Abstract: The method of forming a frame around the screen of a television receiver tube gives a wider strip without using more expensive delay lines. From the picture pattern signals is generated an enlarged blanking out signal formed by two lines. This is obtained by non-additively mixing the undelayed single and double line pattern signals. This gives a height of two lines corresponding to a delay in the horizontal direction. A smaller gating signal for two lines is obtained from the pattern signals in horizontal and vertical directions and the blanking and gating signals are applied to an AND gate connected to a gating stage to obtain the required video signal for the frame.

Patent DE-3107134-A1 (DE)
Title: Device for recording data, particularly printer on scales
Inventor: NERBAS DIETER
IPC: G06K13/24
Filed: 1981-02-26
Abstract: In the device for recording data from a measuring and computing device, a strip-shaped carrier track such as a paper strip is used which is rolled up on a reel hub for forming a reserve of sufficient track length, and is accommodated in a storage container. A transport mechanism pulls the carrier track off the supply reel and supplies it to a printing mechanism, a monitoring station determining the correct run of the carrier track and being intended to detect in time that the supply reel is becoming empty. In spite of these differing monitoring tasks, only a single switch is used in the invention because the sensing elements are constructed to form a common element chain of a number of articulated levers connected to one another, the individual lever arms of which handle the monitoring of the various scanning points. If a fault is detected, the lever arm of the element chain always comes into a pivoted position which moves the switch into an off-position of the device.

Title: Process for dressing mineral mixtures on a wet sieve jigger controlled by compressed air
Inventor: HOBERG HEINZ DR ING
IPC: B03B5/24
Filed: 1981-03-14
Abstract: The invention relates to a process for dressing mineral mixtures on a wet sieve jigger controlled by compressed air, in which a rhythmical upwards and downwards movement of the mineral mixture on a jig bed is generated by pulsed air rhythmically flowing in and out, preferably in pulse chambers in the bottom part of the wet sieve jigger, and is characterised in that the resistance to outflow of the pulsed air is changed in a controlled manner during the downwards movement of the mineral mixture, where the resistance to outflow should be greatest roughly at the moment of the most rapid downwards movement of the mineral mixture. In Fig. 1 of the drawing, a sieve jigger for carrying out the process is depicted, which has exhaust air throttle valves (16), controllable in a pulsed rhythm, preferably in the outflow lines (5) of the pulse chambers (3) on the pulse chamber outlets, which valves are preferably configured as butterfly valves (16'). <IMAGE>

Title: Ultrasonic defect-locating devices
Inventor: TAKEDA HIROYUKI
IPC: B61B10/00
Filed: 1981-07-03
Abstract: An ultrasonic defect-locating device has an axial track and a fixed track (22, 24) extending in the circumferential direction. Said tracks are positioned in a space formed between a pressure vessel of a nuclear reactor and a thermally insulating wall (11A) surrounding the latter and extend in the axial direction or the circumferential direction of the pressure vessel. At an intersection of the axially extending fixed track (22) and the fixed track (24) extending in the circumferential direction, there is installed a rotary track (14) which can be rotated by a chain (16) and whose angle of rotation is limited by two stops (28, 29). A carrier unit (34), which carries an ultrasonic defect-locating unit (70), can be driven on the tracks (22, 24) to carry out the ultrasonic defect location in order to detect any fault which may be present in the pressure vessel. To transfer the carrier unit (34) from the axially extending fixed track (2) to the fixed track (24) extending in the circumferential direction, the carrier unit (34) is first transferred from the axially extending track (22) to the rotary track (14) and, after the rotary track (14) has been swivelled, it is transferred from the latter onto the fixed track (24) extending in the circumferential direction. <IMAGE>

Title: Closures - closure combinations, child-resistant closures
Inventor: HERRMANN NORBERT
IPC: B65D50/04
Filed: 1981-11-21
Abstract: Differing from the customary functional standard "press and turn", the thus required careful material composition and the lacking tamper-proof safeguard in these child-resistant closures which are used, in particular, for safeguarding packages containing dangerous products, the new closure and closure combination child-resistant closure is constructed according to the "pull and turn" principle of functioning, as a result of which not only a variable material composition, but also a specific system and function construction is implemented, specifically in such a way that not only is a tamper-proof safeguard integrated on the child-resistant closure, but also other basic shapes and sealing elements can be selected for said safeguard in and as a normal cap and/or covering cap designed as a screw closure, snap-and-turn closure or snap-and-press closure. Alternatively a normal screw closure, snap-and-turn or snap-and-press closure can be designed in such a way that the latter is constructed in accordance with the given modular system up to the child-resistant closure with a "first" lock set up by the normal cap and/or covering cap and, as an extension, with a "second" lock by means of a tear-off strip, and/or tamper-proof safeguard. <IMAGE>

Title: Method and device for supplying earth or water heat to the condenser of a heat pump
Inventor: WESSA THEO
IPC: F25B30/06
Filed: 1981-12-10
Abstract: For utilising earth heat in association with heat pumps, pipe coils of relatively great extent are laid in the earth. In the event of a leak, so that refrigerating medium or cooling brine can escape into the earth, searching for the leak is extremely difficult. Practically the entire area of ground taken up with the pipes has to be dug up. According to the present invention, firstly the spatial extent required is significantly reduced and moreover a safe barrier is installed between the pipe bearing the cooling medium and the surrounding earth. This takes place by means of a water-filled container to be buried in the earth. Into this container, the installation parts, e.g. pipes, which are surrounded with a thermal insulation layer and conduct the refrigerating medium, are introduced. In the bottom region of the container, the pipes are equipped with freezing elements, e.g. freezing fingers, which penetrate the thermal insulation layer and project into the water, with which the container is filled. Pieces of ice, which melt when the evaporator circuit is switched off or switched over and rise to the surface of the water in the container, are formed around the freezing elements. Advantageously, the entire installation is operated with two containers which are arranged at a sufficient distance in the earth and which are alternately connected to or separated from the heat pump circuit. <IMAGE>

Title: Process for the production of ammonia synthesis gas
Inventor: MECKEL JOACHIM F
IPC: C01B3/02
Filed: 1982-02-24
Abstract: A process is described for the production of ammonia synthesis gas from hydrocarbon-containing starting gases, which are catalytically/autothermally reformed with an oxygen-containing cracked gas and are then subjected to a conversion to give a cracked gas containing carbon dioxide and hydrogen. To simplify the plant which is required for such a process, according to the invention it is proposed that a fraction of the main gas stream is subjected to a multistage pressure swing adsorption plant (PSA plant) arranged in a bypass to the main gas stream and the hydrogen separated during this is returned to the remaining main gas stream, in order by this means to establish the required H2N2 ratio, and that the cracked gas, after conversion, is subjected to a carbon dioxide scrubbing and a methanation.
