Title: Device for connecting a cover and a cylinder in diaphragm brake cylinders
Inventor: HOENIG HANS
IPC: B60T17/08
Filed: 1983-12-09
Abstract: In a brake cylinder, in particular a diaphragm brake cylinder for commercial vehicles, locking means (17) arranged at an equal angular spacing on the circumference of the brake cylinder are provided to connect the cover (1) and the cylinder (3) of the brake cylinder and these locking means allow the cover and the cylinder to be clamped together with a diaphragm (19) in between. The locking means are each formed by a receiving part (21) extending from the cover and a clamping part (23) extending from the cylinder, the receiving part engaging round the clamping part from outside in the assembled position. When the cover and the cylinder are rotated relative to one another, the clamping part (23) which can be introduced into the receiving part for the purpose of assembly interacts with wedge bevels (25), preferably formed on the receiving part, which, to determine the end position, merge into horizontal surfaces. The end position thereby achieved can be fixed by means of locating pins (29), the locating pins (29) being capable of extending through holes in the clamping part and the receiving part which come into overlap. The diaphragm preferably has at its outer circumference a rectangular centering bead (31) which is matched to the shape of the receiving part and of the clamping part. <IMAGE>

Patent DE-3406362-A1 (DE)
Title: Inner shuttering for unitised units
Inventor: DEURINGER GEORG
IPC: E04G11/02
Filed: 1984-02-22
Abstract: In the case of an inner shuttering for unitised units having flexible shuttering walls, horizontally running supporting beams are provided for each shuttering wall, the former being connected in their centre to the respective shuttering wall. A central frame, on which a supporting frame can be vertically displaced, is provided. Stressing cylinders are provided between opposite supporting beams. The supporting frame exhibits bearing surfaces which, in one position of the supporting frame, come to bear against bearing surfaces of the supporting beams and thus hold the latter and the shuttering walls in the shuttering position. The bearing surfaces on the supporting frame merge into inclined surfaces running in the shape of a wedge. In order to remove the shuttering, the supporting frame is lifted and the stressing cylinders are simultaneously actuated. On this lifting movement, the bearing surfaces of the supporting beams slide along the wedge-shaped, inclined surfaces on the supporting frame, as a result of which opposite supporting beams are moved towards one another and the flexible shuttering walls thus assume a concave shape.
Patent DE-3407782-A1 (DE)
Title: Bearing mat for motor-vehicle-parking means
Inventor: SCHUCKEL WOLFGANG
IPC: E04H6/42
Filed: 1984-03-02
Abstract: The bearing mat is laid on the parking surface and can be driven upon and walked upon. The bearing mat (4) engages with two ribs (1) into one transverse channel (2) in each case and is thus supported on the base (3) of the transverse channel. Although the beads (5) of the parking surface prevent the bearing mat from moving or slipping, even when the parking surface is sloping, the transverse channels (2) remain fully functional and can thus laterally drain away dirty water, etc. In this arrangement, the bearing mat being supported on the parking surface prevents an excessive loading and deformation of the bearing mat and ensures a long service life. <IMAGE>

Title: Apparatus for flooding a porous material sample with an amount of a gas, in particular for determination of the specific surface area
Inventor: FRISCH BERTRAM PROF DR
IPC: G01N15/08
Filed: 1984-03-19
Abstract: An apparatus for determining the specific surface area of a porous material sample by the BET process has a sample vessel (22) which is connected only via lines as short and narrow as possible to a vacuum connection (29), a connection (30) for feeding a gas and a pressure gauge (27). The connection for feeding the gas is composed of a septum (30). The gas is fed in a measured quantity by means of a gas syringe (32) piercing the septum. The pressure gauge (27) is a gas pressure sensor operating on the principle of a piezoelectric transducer. The connection lines are realised by boreholes in a conduit element (26). In this apparatus, the volume of a gas measuring vessel required in the known apparatuses is dispensed with. The results are thus much more sensitive. <IMAGE>

Title: Method for protecting against unauthorised access to data stored in a data centre
Inventor: DILLIG JULIUS
IPC: G06F21/44
Filed: 1984-03-21
Abstract: A data centre (DZ) only releases a data exchange with a terminal (EG) to which a data network is connected which is also accessible to unauthorised users, when it has established a first connection to the terminal (EG) and the latter has established a second connection to the data centre (DZ). The terminal (EG) only establishes the second connection when the variable identification word previously allocated to it corresponds to the identification word transmitted by the data centre. The data centre only forms a second variable identification word when the first variable identification word previously allocated to the terminal corresponds to the identification word transmitted back to the data centre (DZ). The data exchange is only released by the data centre (DZ) when the triggering of the first connection and of the reception of the first variable identification word transmitted back from the terminal (EG) occur within a predetermined time. <IMAGE>
