Title: Control for chemisorption filters
Inventor: HOELTER HEINZ DIPL ING
IPC: B60H1/00
Filed: 1985-11-19
Abstract: The main application P 3502855.6 relates to an air-conditioning system which is controlled according to temperature and humidity. By this measure it is aimed, inter alia, to achieve the end that chemisorption filters recently installed in motor vehicles operate under favourable conditions, which, however, is not always ensured by the control of the air-conditioning system. In order to remedy this deficiency, it is proposed according to the invention that the chemisorption filters, in the event of pollution, are only switched on if the temperature and relative humidity in the vehicle cab are optimum for the operation of the chemisorption filters. The chemisorption filters are controlled via humidity and temperature sensors.

Title: Method for arranging a dam wall and guide member for applying the method
Inventor: HEES BERNARDUS VAN
IPC: E02D13/02
Filed: 1986-06-27
Abstract: In a dam wall, concrete dam wall elements (3) are held between the flanges (4) of H-sections (2) and use is made of a guide member (6). The method comprises a front edge (7), two arms (12) which are pivotally connected thereto and are pivotally connected at their other end to a beam (15) which extends parallel to the front edge (7). Means (17, 18) are provided for the purpose of pressing away the front edge (7) of the beam (15), which is located in a freshly driven H-section (2), so that a slot is formed in the ground. After the front edge (7) has been positioned at a distance from the beam (15), the beam is pulled back towards the front edge, and a subsequent H-section (2) is driven into the ground and thereafter a dam wall element (3) is arranged in the slot. <IMAGE>
Patent DE-3621883-A1 (DE)
Title: Rack for storing bars or sections with pull-out trays
IPC: B65G1/04
Filed: 1986-06-30
Abstract: A rack (1) serves to store bars (2), in particular rolled steel sections, tubes, solid material or the like. It has a rack frame (3) with compartments (4) which are arranged one above the other and are each subdivided one next to the other into individual drawer-like trays (6) which can be pulled out in the longitudinal direction of the bars (2) to be stored and are mounted on rollers (5). The rack (1) furthermore includes at least one additional, preferably mobile supporting framework (7) which supports the respective tray to be extended during the extension and above all in the extended position, and for this purpose can be detachably coupled to the tray (6) in each case. The coupling point (8) for the supporting framework (7) is in this case set back on the respective tray (6) with respect to the front face (9) of the latter in the pull-out direction and is thus arranged inside the rack frame (3) when the tray (6) is retracted into the rest position. In the coupling position, the respective tray (6) therefore has a projecting length (12) with respect to the supporting framework (7), with the result that a better weight counterbalance at the supporting framework results and the free span of the extended tray (6) is reduced, so that low bending stresses occur and the trays (6) can therefore be designed in a lighter and more space-saving manner. <IMAGE>

Title: Small test rods for film circuits
Inventor: SCHMIDT DIETER DIPL ING
IPC: G01R1/04
Filed: 1986-06-30
Abstract: When locating faults in the production and for investigation and optimisation in the development of thin film and thick film circuits, it is necessary to exchange individual components which was previously mainly done by soldering and unsoldering; apart from the risk of destroying the film circuits and/or the chips, this is a cumbersome way of working. According to the invention, it is proposed to attach to the end face of a rod-shaped insulating rod a corresponding chip which is pressed with its contact lands onto the contact areas of the corresponding film circuit for test purposes. It has been determined by tests that the surprisingly simple solution provides for adequate contact from direct current up into the gigahertz range.
Patent DE-3622744-A1 (DE)
Title: Method for extracting vapour, fat- or oil-containing air or the like, and extractor hood for carrying out the method
IPC: F24C15/20
Filed: 1986-07-07
Abstract: The invention relates to a method for extracting vapour, fat- or oil-containing air or the like, which rises from a vapour source, and to a corresponding extractor hood. One or more supply pipes (9) for external air which has not been air-conditioned project from above into the vapour-collecting chamber (1) down to the lower region thereof. Attached to the lower end of these supply pipes (9) is a nozzle pipe (10) which extends through the vapour-collecting chamber (1) transversely and approximately midway between front wall (2) and rear wall (3). The nozzle pipe (10) has a slotted nozzle (12), through which the supplied external air is blown into the vapour-collecting chamber (1). A flat injection air flow, which is directed obliquely upwards and perpendicularly onto the filter (7) and entrains the vapour, is formed. The supply pipes (9) are of narrow construction compared with the length of the nozzle pipe (10). The rising vapour can thus flow round the supply pipes (9) and the nozzle pipe (10). As a result, the vapour is conveyed both at the underside and at the upper side of the injection air flow. The entraining effect of the injection air flow is thus utilised on both sides. The flow conditions within the vapour-collecting chamber (1) are optimised; the extractor hood operating according to this principle extracts the vapour highly effectively and is notable for its reduced power consumption. <IMAGE>

Title: Tennis practice apparatus
Inventor: NIENHAUS BERTHOLD
IPC: A63B69/38
Filed: 1986-07-28
Abstract: The tennis practice apparatus has been developed for practice purposes, for beginners and advanced tennis players. It is relatively simple in construction and can be easily and rapidly dismantled for transportation. The practice apparatus is provided with an electronic system which makes it possible both to carry out reaction training and to practise ground strokes and special strokes. The balls pass from two ball tubes (see drawing) to the ball release aperture. After release of the ball, it falls perpendicularly to the ground and, depending on the height setting of the apparatus, bounces up from a defined point on the ground, from which it can then be struck. Similarly, with a higher setting of the apparatus, the ball can be played directly from the air or after bouncing up onto a frame strung with racket strings, as a volley, smash or serve. The apparatus can be set to manual or automatic operation. <IMAGE>
