Patent DE-3344041-A1 (DE)
Title: Safety-belt buckle
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: A44B11/25
Filed: 1983-12-06
Abstract: The invention relates to a safety-belt buckle as a fastening part in safety belts, which is constructed as a so-called servo-buckle. The load-absorbing bolt 3 is mounted tiltably on the buckle holder 6 and, in the event of a load caused by an accident, is supported on a crossbolt arranged above the buckle tongue 7 between the two housing legs 31. The small opening stroke obtained thereby allows a low constructional height of the buckle. The supporting bolt 5 is mounted so as to be longitudinally displaceable in guide grooves of the sliding button 12. The supporting forces occurring under load are introduced into the housing 2 via the sliding button 12. This, as a result of the increase in friction, gives rise to a safeguard against displacement of the button 12 in the event of an accident. The design of the hook region 20 in the manner of a C-section allows a reliable transmission of the accident load from the buckle tongue 7 into the load bolt 3. The load transfer into the buckle holder 6 takes place both directly from the load bolt 3 and from the housing 2, without a connecting element being interposed, as a result of an appropriate design of the parts themselves which are to be connected. For a especially high loads, the constructive design of a two-shear connection is possible. The resulting inner forces in the event of an accident load produce moments which keep the buckle in the closed position, that is to say no opening spreading forces. The actuation of the load bolt 3 takes place by low-friction tilting. The constructive design of the buckle ... Original abstract incomplete. <IMAGE>

Title: Permanent-magnet system having a variable magnetic force
Inventor: CLAUSSEN HANS-JUERGEN DIPL ING
IPC: H01F7/04
Filed: 1984-02-02
Abstract: The invention relates to a permanent-magnet system for conveying ferromagnetic loads and for braking transport goods on roller beds, consisting of stationary pole segments, pole limbs and pole shoes composed of ferromagnetic material, and of a permanently magnetic rotating body whose outwardly acting attraction force can be varied by twisting until it becomes ineffective. The aim of the invention is that the dimensional inaccuracies which cannot be avoided in the production of a permanent-magnet system having an air gap have no influence on the magnetic characteristic data, and it is hence an object of the invention to design the magnetic circuit air gaps, which are a feature of the principle, to be minimal. This is achieved according to the invention in that a continuous shaft (1) is arranged in the ends (2) of the magnet system, on which shaft (1) a plurality of axially magnetised, permanently-magnetic rings (3, 4, 5), form a magnet block, are arranged, and the magnet block is provided with pole discs (8, 9) at the ends. <IMAGE>

Title: Device for measuring the area of the projection of a specimen onto a plane
Inventor: SCHUESSLER HANS-H DIPL ING DR
IPC: G01B11/28
Filed: 1984-03-15
Abstract: The invention relates to a device for measuring the area of the projection of a specimen onto a plane. In this case, a light beam emitted parallel to the direction of projection is traversed at right angles thereto in rows or a zigzag fashion over the specimen or its contour, it being possible for the traversing device to hold the position of the light beam continuously in terms of its coordinates. It is determined by means of a sensor whether the light beam passes the specimen and enters the sensor or whether the light beam is interrupted by the specimen. In order to be able to save an additional traversing device for the sensor, the sensor is arranged on the same traversing device and is moved along with it. All that is arranged on the opposite side is a mat projection screen on which the light beam grazing the specimen generates a light spot. The emitted light beam and the returning light are reflected in a common beam corridor via a beam splitter. The telescope lens of the sensor, which is focused on the light spot on the projection wall, has the same axis as said beam corridor. Various possibilities are indicated for suppressing parasitic light. Such devices are required to determine the drag coefficient of bodies in a flow such as, e.g. vehicle bodies, or for the precise determination of the contours of manually produced prototype parts.

Title: Temperature-stabilising equipment for photographic developing tanks
Inventor: KUERTEN ARNO
IPC: G03D13/04
Filed: 1984-03-16
Abstract: In tanks equipped for temperature stabilisation it is possible for all processes of development to be carried out as programmed using the temperature-stabilising equipment alone without the aid of colour processors or other external means. There is thus a saving not only in the relatively high procurement costs of a processor, rotational development of films and paper prints require only an inexpensive agitation unit, but also in the time and energy which the temperature control of a relatively large quantity of water (approx. 20 litres in the case of small processors) requires before the start of operation.

Title: Process for the expedient production of the redox potential in the simultaneous separating out of SO2 and NOx
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1984-11-13
Abstract: The invention relates to a process for the simultaneous separating out of SO2 and NOx downstream of power stations having differing pHs in the scrubbing stages. It has already been proposed in a process of this type to add, as inoculant, sodium dithionite or an equivalent reducing agent to the scrubbing circulation to increase the redox potential. To establish the redox potential, according to the invention it is proposed that this is established in a purely chemical way by addition of reducing agents such as sodium dithionite and similar reducing agents and/or that this is additionally or solely established in an electrochemical way.
Patent DE-3441568-A1 (DE)
Title: Exhaust gas purification process
Inventor: STEINBACHER KARL
IPC: B01D53/34
Filed: 1984-11-14
Abstract: For the purification of exhaust gases which are produced in the preheating of scrap in steel works, a process is proposed in which, in addition to electrostatic dust filtering, deodorisation is also carried out by ozone addition. The deodorisation is carried out directly following the electrostatic dust filtration in an empty zone arranged in the dust filter housing. In an apparatus for carrying out the process, the length L of the empty zone in the direction of flow, measured in metres, should be at least five times the gas velocity v, measured in metres per second. In this manner, exhaust gases from scrap preheating can not only be de-dusted to the prescribed extent, but can also be deodorised in an economical manner. It is important that the addition of ozone into the exhaust gas stream is carried out only when this has already been essentially de-dusted in order that undesired reactions of the ozone with the dust are avoided and that the smallest possible addition of ozone can be employed. <IMAGE>

Title: Wrist-watch which can be turned over
Inventor: EISEMANN MICHAEL
IPC: G04B37/04
Filed: 1985-04-04
Abstract: The subject-matter of the invention is a wrist-watch which can be turned over and can be put on both with the front side and with the rear side showing. Arranged on the front side of the watch housing and/or rear side of the watch housing is in each case at least one display which displays, for example, the time, stop-watch time or the date. According to a particular embodiment, a buckle 12 is fastened on the strap part 1a by means of a buckle holder 10 such that it can rotate about a pivot point 14. The buckle 12 has two operating positions, the angular positions of which are spaced apart from each other by 180 DEG , in which it is secured with the aid of catch means 15a'' and 15b''. By rotation of the buckle, the bar 13 can be fastened at the fastening holes of a second strap part and, on the one side, can hold the front side and, on the other side, can hold the rear side of the second strap part. The turning merely of the buckle makes possible more simple and cost-effective production. A further advantage is that the wrist-watch permits a different design or colouring of the strap sides and the watch housing sides for different purposes, for example for use as a sports or fashion watch.   <IMAGE>
