Patent DE-3036635-A1 (DE)
Title: Safety valve lock for steam steriliser - has two interlocked driving members ensuring opening in stages
Inventor: BACHEM GUENTER
IPC: F16J13/24
Filed: 1980-09-29
Abstract: A driving member (1) moves the locking members in and out of engagement. A second driving member (2), which can be actuated independently of the first, works with it so that when the first one is engaged, the second moves a first locking component (3) to prevent all movement. On moving this locking component into a second position, the second driving member then encounters a second locking component (4) moved by the first driving member and in a first position. When the first locking component is in its second position, the first driving member is movable into an intermediate position between the engaged and the free positions of the locking members (10), in which its further movement is prevented by a third locking component (5) moved by the second driving member. The second locking component is then in a second position in which the third can be moved by the second driving member into a further position, which enables the first driving member to move into the open position of the locking members.

Title: Relating tray depth to gas discharge rate - in column reduces splashing during degassing of liq.
Inventor: HACHMANN KLAUS DIPL ING
IPC: B01D19/00
Filed: 1980-11-05
Abstract: Splashing and effervescence in a liq. being degassed during descent down a column contg. a series of overflow trays are reduced by matching the liq. depth in each tray to the amt. of volatile material normally liberated in that tray. This is effected by varying the height of the overflow weirs so that a large amt. of volatile material is liberated from a small depth and vice versa. The air equiv. rate of passage of volatile material through the liq. surface should be 0.02- 1.0 (0.03l0.1) metres/secs. Used for reaction columns or material exchange columns wherein gas and liq. are of different compsn. and avoids liberation of excessive amt. of volatile material which can entrain liq. droplets which are then undesirably returned to liq. body. All column components provide optimum contribution to degasification, and total column size is reduced.

Title: Supplying reagents from container on support plate - by extn. near centre of plate by suction through movable needles
Inventor: KRUEGER BERND
IPC: G01N35/10
Filed: 1980-11-10
Abstract: Reagents in a number of containers mounted at the perimeter on a fixed horizontal support plate pass radially towards the centre of the circle for extn. from one of an equal number of small apertures through an extn. needle which can move in the vertical direction at least and is connected to suction means. The apertures are concentric with a rotary bearing for the plate. The containers are mounted on sectors, and cam mechanism is used to bring the needles into alignment with the extn. apertures. The needle conduit may have a cranked section. One sector of the plate has means for rinsing the needle and ejecting the rinsing fluid. Since the containers move intermittently but do not rotate, transit time is reduced and acceleration forces are low. The containers may be readily replaced, e.g. for change of reagent.

Title: Injection moulding corrugated thimble shapes - using compressed air when mould opens to inflate moulding and blow off male tool
Inventor: METTENBRINK HERBERT
IPC: B29C45/43
Filed: 1980-11-15
Abstract: A corrugated thimble shape of injection moulding e.g. polyethylene seal caps is ejected from the male core tool by admitting pressure agent e.g. compressed air between the surfaces of the core and the female tool wall when the mould is opened. Compressed air is continuously fed to the grooves (14). When the mould is closed and polymer has been injected and cooled, the female tool (6) is opened. The spring-loaded mounting plate (15) is moved to its stop ring (18), moving the rod (12) and hence the head (11) slightly away from the faces (13). Air thus flows between the core (9) and the inside surfaces of the moulding. The moulding is inflated and blown off the core (9). Method makes possible injection moulding and therefore high output, low cost, close dimensional tolerances and low rejection rate.
Patent DE-3100090-A1 (DE)
Title: Device for converting solar radiation into technically useful energy
Inventor: LANGE LUDWIG DIPL PHYS
IPC: F24S20/20
Filed: 1981-01-03
Abstract: The invention relates, in particular, to the efficient generation of high temperatures in the working medium by concentrating the energy available from the sun onto an absorber, in such a way that said absorber is fixed and a reflecting system which has the form of an internally mirrored hollow conical system rotates about said fixed absorber about a fixed axis in accordance with the parallactic mounting known from astronomy. Swivelling said reflecting system about said fixed axis is performed in accordance with the annual declination. In order to ensure that the entire concentrated solar energy flux impinges on the absorber surface, the surface surrounds the spatial envelope of the focal line (Fig. 2), which rotates diurnally about the fixed axis - which has a polar alignment - and is swivelled seasonally owing to the declination with respect to the fixed axis (Fig. 2). This solution avoids expensive rotary sleeve connections, with which additional problems would be expected concerning tightness and reliability. The principal possibility of application is in the generation of high temperatures, including in conjunction with high pressures, so that process heat can be generated directly or indirectly, for example for seawater desalination, or for the acceleration of fermentation gas cycles, steam power cycles or gas turbine cycles. <IMAGE>

Title: Activator combination
Inventor: QUANTE HEINRICH ANTON
IPC: C04B28/16
Filed: 1981-02-09
Abstract: To accelerate setting in the production of moulded and structural parts of high flexibility from ground rhoboidal-crystalline, anhydrous calcium sulphate and water, a mixture of 0.2 to 1.2% by weight of potassium hydroxide and 1.5 to 5.0% by weight of potassium alum is used as an activator. This results in a shortening of the curing time and a reduction of the energy consumption. The moulded and structural parts have a high flexibility, even if the proposed activator mixture is formed by chemical reaction when mixing up the calcium sulphate with water.

Title: Self-commutating converter
Inventor: DEPENBROCK MANFRED DR ING PROF
IPC: H02M7/521
Filed: 1981-04-23
Abstract: The invention relates to a self-commutating converter for rectifying and invertor operation for supplying an AC load from a DC voltage source (1). The arrangement is formed from an unbalanced reverse-parallel connection of an uncontrolled partial converter (2) and a self-commutating partial converter (3) which consists of valve branches having reverse-conducting thyristors (3a, 3b, 3c, 3d). Connected in series with the reverse-conducting thyristors are smoothing inductors (4a, 4b) as well as commutation inductors (9a, 9b) and primary windings (10a, 10'a) of current transformers (10, 10') of an AC intermediate circuit (5). The load (7) and the commutating capacitor (8) of the AC intermediate circuit (5) are connected to the AC connections of the uncontrolled partial converter. The secondary winding (10b) of the current transformer (10) impresses a current on an auxiliary DC voltage source (12) such that sufficient energy is in each case extracted from the smoothing inductors by amplitude control of the auxiliary DC voltage or by saturation control of the current transformer (10) in order to set the current through the smoothing inductors such that the alternating currents flowing via the AC intermediate circuit (5) outside the commutation intervals are always somewhat larger than the peak values of the currents in the load (7). <IMAGE>

Patent DE-3140814-A1 (DE)
Title: Automatic audio/video adaptor
Inventor: BEMMERER KLAUS ING GRAD
IPC: H04N5/44
Filed: 1981-10-14
Abstract: This adaptor is mainly used in domestic video technology, in which audio/video devices such as video recorders, television sets with audio/video connection, video disc players, video cameras and the like having different connection technologies are used for the audio- and video-frequency input and output lines. Essentially, there are two types of connecting technologies. In one, one line in each case is used jointly as signal input and as signal output for audio and video. In the other connecting technology, separate signal inputs and outputs are present for audio and video (Figure 1). If two video devices of different connecting technology are to be connected to one another (for example video recorder and television set with audio/video connection), the lines must in each case be manually replugged or switched over when the direction of signal flow changes. This process can be handled automatically by the audio/video adaptor described in that it recognises from the video signals supplied to it whether one of the connected devices is operated as signal source or sink and correspondingly carries out the switch-over process. <IMAGE>

Title: Process for the preparation of low molecular weight olefins
Inventor: HAEUSSINGER PETER DIPL CHEM DR
IPC: C07C11/04
Filed: 1982-06-03
Abstract: A process for the preparation of low molecular weight olefins by catalytic cleavage of methanol is proposed. The cleavage gas obtained is first subjected to a C2/C3 separation and, after cooling to low temperatures, light components are separated from the C2 fraction and the remaining C2 fraction is subjected to an ethylene/ethane separation. Separated ethane is conducted to a thermal cleavage and reacted to give a cleavage gas which is dissociated together with the cleavage gas from the methanol cleavage.
