Patent DE-3466843-D1 (DE)
Title: Current driven flyback power supply
Inventor: JOSEPHSON ELLIOT
IPC: H02M3/335
Filed: 1984-02-17
Granted: 1987-11-19
Abstract: A current driven flyback power supply has a transistor current switch which periodically couples a primary current through the primary winding of a power transformer which is connected between a source of DC and the collector of the current switch. A current transformer has a first winding coupled between the primary winding and the collector of the current switch, and a second winding which develops a drive current proportional to the primary current. The drive current is coupled to the base of the current switch and increases proportionally with the increasing amplitude of the primary current. An electrical switch shorts the drive current to ground to turn off the current switch so that stored energy in the power transformer is coupled out through its secondary winding to an output rectifier circuit which develops the output DC voltage. After the stored energy has been completely coupled out through the secondary winding, a first current pulse is developed to turn on the current switch to initiate the primary current. During high output power loading conditions, a second current pulse is developed at a selected point in time after the current switch turns off and prior to the stored energy being completely coupled out through the secondary winding. The second current pulse turns on the current switch whereby the initial primary current is boosted in amplitude by the residual stored energy in the power transformer.

Title: Boat with stabilizing flaps
Inventor: KAYE ALEX R
IPC: B63B7/02
Filed: 1984-02-01
Granted: 1988-02-25
Abstract: A boat having a pair of bottom banels provided with respective flaps to cause the stern of the boat to ride relatively high in the water when the boat is driven forwardly in the water by an outboard motor. In one embodiment, the flaps pivot downwardly and provide drag for the stern in response to forward movement of the boat. In two other embodiments, the flaps provide planing surfaces near the stern. The boat can be collapsible in which case the bottom panels mate with resilient side panels to form, when collapsed, a flat sandwich configuration which, by the means of improved straps, can be carried on the top of a vehicle or can be hand-carried. An improved bracket for the stern of the boat is used to permit positive attachment of an outboard motor to the boat.
Patent DE-3471883-D1 (DE)
Title: Process for producing sterile air for medical use, and apparatus for carrying out this process
Inventor: DELACHAPELLE HENRI
IPC: A61M16/00
Filed: 1984-01-20
Granted: 1988-07-14
Abstract: Apparatus for producing sterile air suitable for being administered to intensive-care patients in hospitals using atmospheric air. The medical-grade air is free of gaseous contaminants and germs, at a cost substantially lower than when such air is prepared by mixing pure nitrogen with pure oxygen. Atmospheric air is compressed through at least one dry-piston compressor, condensing water vapor out of the compressed air through expansion into a buffer tank, filtering out dust particles down to micron size in a prefilter, drying the air through an adsorption desiccator unit and eliminating gaseous contaminants through an adsorption-desorption unit. A second dust filter is provided for trapping any dust released from the adsorption units. Biological contaminants, such as viruses and bacteria, are eliminated by flowing through a sequence of three biological filters of the coalescence type, and finally through a cold sterilizing unit. The desiccator unit and the unit for the elimination of gaseous contaminants contain a compound of metal oxides with silicates K, Na and Mg, the amount of this compound being larger in the elimination unit than in the desiccator unit.

Patent DE-3562081-D1 (DE)
Title: Hinged bearing
IPC: F16D1/08
Filed: 1985-12-23
Granted: 1988-05-11
Abstract: A coupling for rotatably connecting a reel with a drive shaft has a support which is fast with the drive shaft. The support is provided with a recess which is designed to receive a complementary stub shaft fixed to the reel. The recess has an open side via which the stub shaft may be inserted in and removed from the recess, and an arresting element in the form of a wheel is provided to close the open side. The arresting wheel is pivotally mounted on the support for movement between a release position in which the open side of the recess is exposed to permit insertion of the stub shaft in, and removal of the latter from, the recess, and an arrest position in which the open side of the recess is closed to prevent release of the stub shaft. The pivot axis of the arresting wheel extends at right angles to the axis of rotation of the support. A pawl is pivotally mounted on the arresting wheel for movement between an operative and an inoperative position, and the pivot axis of the pawl is parallel to that of the arresting wheel. The pawl has a free end portion, and the support is provided with a cutout which receives this end portion when the arresting wheel is in its arrest position and the pawl is in its operative position. The pawl an the cutout are designed in such a manner that, in the operative position of the pawl, the latter prevents unintentional movement of the arresting wheel from its arrest position to its release position. The pawl has an arm which may be gripped in order to pivot the pawl to the inoperative position in which the pawl is clear of the cutout. The arresting wheel may then be moved to its release position.

<??>According to a further embodiment, the reactive antioxidant compound is made to interact with the polymer so that the stabilising compound becomes chemically bonded to the polymer chains. 
<??>In all cases, stabilised polymers are obtained containing the antioxidant compound in a form which is not removable from the polymer. 
<??>The process for preparing the reactive antioxidant compounds and for preparing the stabilised polymer compositions are also described.
