Abstract: Method and apparatus for carrying out biochemical reactions in particular for cell-free polypeptide biosynthesis. A bioreactor has, within a housing, a reaction chamber containing a producing system as well as a supply chamber separated from the reaction chamber by means of a semi-permeable membrane and containing a liquid serving as supply medium for the producing system. The supply chamber is subdivided within the bioreactor into a first partial chamber and a second partial chamber which are each connected to the reaction chamber via a semi-permeable supply membrane and which are connected to each other by means of a connection conduit.

Abstract: The invention relates to a device for filling a restraint device, in particular an impact cushion (airbag) for the protection of the occupants of a motor vehicle, with the following features. The restraint device is filled by an inert gas or gas mixture stored in a pressure container; the pressure container has an outlet opening which is closed by a burstable membrane; a module for opening the membrane is associated with the outlet opening; the module has an ignition unit; the igniter case is surrounded by a toroidal propellant chamber; for the ignition of the propellant stored in the propellant chamber, the igniter case has, in addition to axial nozzles, further nozzles directed radially outwards and finally a flow control is provided which directs the hot gas, produced by the propellant, onto the membrane.

Abstract: The invention concerns a tubular gas generator for the filling of an airbag in a retention system for occupants of motor vehicles, whereby two separate combustion chamber units have a common connector and each combustion chamber unit has an ignitor unit with respective filters.

Abstract: A gas generator (10) which generates propellant gas for inflating a gas bag in an air bag system comprises a housing (11) having a combustion chamber (21) which is formed by an upper part (12) of the housing and a lower part (13) of the housing in the interior of the housing (11), discharge openings (32) in the housing (11) for the exit of the propellant gas from the housing (11) into the gas bag, a filter device (30) upstream of the discharge openings (32) and an ignition device (23) for igniting a solid propellant (22) contained in the combustion chamber (21), the propellant gas escaping from the combustion chamber (21) being directed out of the housing (11) via flow chambers (29).

Abstract: Gas generator for a safety system for the protection of occupants of motor vehicles, with a tubular or cylindrical housing, wherein the gas-generating solid propellant is contained in a combustion chamber within which volume-equalizing structure is arranged, surrounding the propellant, both in the direction of flow--along the principal axis--and peripherally over the entire circumference.

Abstract: An essentially cylindrical gas generator for generating combustion gases. The gas generator includes a housing having gas outlet openings; a combustion chamber surrounded by the housing; gas-generating fuel disposed in the combustion chamber; an igniting device disposed in the combustion chamber for igniting the fuel; a first filter disposed between the fuel and the gas outlet openings for prefiltering generated gases upon passage thereof from the combustion chamber through the first filter toward the outlet openings; a second filter disposed between the first filter and the outlet openings for filtering the gases upon passage thereof from the first filter through the second filter; and a generally tubular body surrounding the second filter. The tubular body is surrounded by the housing, and is composed of a plurality of third filters and a plurality of guide plates circumferentially alternating with the third filters.

Abstract: A vacuum breaking-force booster has a sequential control valve without a response path. First and second pressure chambers are separated by a diaphragm with a diaphragm disk in it and the diaphragm disk is connected with a shaft that supports a radially inward valve seat which presses against a spring biased sealing disk. Communication between the first and second chambers is past the inner valve seat. A shiftable sleeve extends through the lid of the first of the chambers and includes a collar which engages the inside of the lid for determining the maximum extend the sleeve can move out of the lid. A pressure piston extends through the sleeve. A bridge connects the sleeve with the pressure piston for moving together. An elastomeric bellows attaches the sealing disk to the sleeves and the pressure piston; the outer valve seat is defined on the sleeve for engaging the sealing disk. A spring normally urges the sealing disk toward both of the valve seats.

Abstract: An assembly of a master brake cylinder and an associated power cylinder of larger diameter, disposed in front of the dashboard, is held together under tension by a stirrup-shaped retainer with a bight embracing the free end of the master cylinder and two legs anchored to the dashboard, these legs traversing the power cylinder. A roll membrane inside the power cylinder, forming a flexible partition that divides its interior into two chambers between which a pressure difference is developed to operate the master cylinder, has cuffs attached to two guide tubes rigid with at least one wall of the power cylinder, these tubes being traversed by the retainer legs.

Abstract: An assembly of a master brake cylinder and an associated power cylinder of larger diameter, disposed in front of the dashboard of an automotive vehicle with an extension traversing that dashboard, is held together by a flexible retainer such as a strap or a wire embracing the master cylinder and at least part of the outer periphery of the power cylinder under tension. The extremities of the retainer may be anchored directly to the dashboard and its center part is braced against the front end of the master cylinder by an adjustable tensioning device.

Abstract: A transmitter cylinder is used in a hydraulic system and particularly the ake system of an automotive vehicle. To prevent undesired access into the transmitter cylinder, a lock part is installed at the pedal facing end of the cylinder. The lock part is an annulus. The pedal connected piston extends through the lock part and into the transmitter cylinder. The annular lock part is shaped so that its inner bore will guide and center the piston projecting into the cylinder. A locking element for holding the lock part in the cylinder bore is defined. It is either a radial projection from the lock part or it is a retaining ring held in a groove on the exterior of the lock part. In either case, the locking element projects into a groove defined in the interior of the cylinder bore, which retains the lock part in the cylinder bore against undesired extraction. The lock part may be a hollow annulus or a solid body. The lock part is appropriately configured to permit its extraction with appropriate tools.
