Patent DE-3067964-D1 (DE)
Title: A distillative method of separating a methane overhead product from a mixture thereof with an acid gas, and the products thus obtained
Inventor: HOLMES ARTHUR SHERWOOD
IPC: C07C7/20
Filed: 1980-11-06
Granted: 1984-06-28
Abstract: A method of eliminating solids formation in a cryogenic distillative separation of acid gases from methane is disclosed. This method comprises adding a solids-preventing agent to the solids potential zone of the distillation column. Typical solids-preventing agents are one or more C2-C5 alkanes, or other nonpolar liquids which are miscible with methane at the column conditions. The elimination of solids formation permits a more complete separation to be achieved.

Title: Single use ribbon cartridge with frangible resistive element for restraining the translating take-up spool
Inventor: CRAFT JAMES ALEXANDER
IPC: B41J33/26
Filed: 1981-10-20
Granted: 1984-09-27
Abstract: In ribbon cartridges (10) including a ribbon take-up spool (20) which is peripherally driven by a spacially fixed driving roller (18), it is necessary for the take-up spool (20) to move away from the driving roller (18), as the ribbon (22) accumulates on the spool (20), while remaining in proper driving engagement with the roller (18). According to the invention, this is achieved by a frangible member (24) which resists the movement of the take-up spool axle (28) except when caused by ribbon accumulation. Frangible member (24) may either be formed as an integral part of the cartridge walls or be bonded thereto. Member (24) will break or tear as axle (28) is forced away from roller (18) by the increasing diameter of take-up spool (20).

Title: Apparatus for determining the blood group of an individual
Inventor: HUBEAU JEAN-PIERRE
IPC: G01N33/48
Filed: 1982-11-12
Granted: 1985-10-10
Abstract: An apparatus for determining the blood group of an individual. The apparatus comprises a carrier plate slidably mounted for horizontal movement and adapted to support an analysis holder. The analysis holder is provided with several series of cavities adapted to hold blood samples, agglutination reactants, and mixtures of the two for analysis. A block of distribution needles associated with pumping means is slidably mounted for vertical movement. The number of needles in the distribution block and the number cavities in each series in the analysis holder is the same. The movements of the block of distribution needles and of the carrier plate are synchronized, when initiated, so as to cause blood samples and reactants to be pumped from their respective cavities in the analysis holder through their corresponding needles to analysis cavities. Analysis is by optical density detecting means associated with means for displaying the analytical results.

Title: Device for conveying a progression of overlapping sheets of paper
Inventor: EMRICH HELMUT
IPC: B65H5/24
Filed: 1982-08-09
Granted: 1986-03-06
Abstract: A conveyor for sheets fed to or from a printing press in an overlapped stream, the table having longitudinal slots formed therein laterally spaced from one another. A perforated endless conveyor belt is trained over the table. An enclosed chamber extending substantially the length of the table communicates directly with the slots, the chamber being convergently shaped terminating at its lower end in a throat. An axial flow fan in the throat draws air through the perforations so that a stream of overlapped sheets on the belt will be held in contact therewith for transport from one end of the table to the other. The fan is chosen to have a flow characteristic such as to maintain the pressure differential across the fan approximately constant notwithstanding variations in the rate of air flow resulting from gaps in the stream. The belt is in two narrow, laterally spaced sections dimensioned to fit into the slots.

Title: Hydraulic circuit for a load-driving motor
Inventor: BARKER GARY THOMPSON
IPC: F15B13/01
Filed: 1984-10-09
Granted: 1987-08-13
Abstract: A load control system is disclosed for preventing the uncontrolled lowering of a load should a line failure occur in a hydraulic system. The system is designed to be used with a hydraulic cylinder having a movable piston therein which divides the cylinder into a head end and a rod end. Attached to the piston and extending out of the hydraulic cylinder is a piston rod which has a load secured to its free end. The load control system includes a source of pressurized fluid, the flow of which is selectively controlled to the hydraulic cylinder by a control valve. Positioned between the control valve and the head and rod ends of the hydraulic cylinder, respectively, are first and second valves each of which is normally biased towards a closed position by a common pressure. The first and second valves are urged toward an open position by fluid pressure taken between the control valve and the first valve and are movable by this fluid pressure in a proportional manner with the second valve being opened first. The second valve is also physically mounted directly to the hydraulic cylinder such that if a line breakage occurs, the load will still be unable to drop.

Title: Improvements in or relating to body supports for use in a bed or seat
Inventor: MILLER JOHN E
IPC: A47C23/00
Filed: 1984-02-08
Granted: 1988-05-19
Abstract: The body support has a number of resilient support members or springs that are movable between a retracted or collapsed, inoperative position and an extended, operative position.

Title: A surgical stapler
Inventor: STORACE ANTHONY
IPC: A61B17/08
Filed: 1984-08-21
Granted: 1989-09-28
Abstract: A surgical stapler having a pivotable trigger in a housing and a cartridge of surgical staples, has a moving anvil which receives one staple at a time in its open configuration. A forming blade moves to engage and capture the staple between the forming blade and the anvil and drive the staple away from the cartridge allowing the user to see and place the points of the staple at a desired location on the tissue. Further movement of the forming blade pressing upon the top of the staple forces the staple legs to pierce and close joining adjacent edges of tissue. A detent prevents reversibility of the trigger and return of the staple after and the trigger reaches a pre-cock position, allowing the user to relax his hand while the staple remains exposed, until the trigger stroke is completed and the staple is closed and stripped from the anvil.
Patent DE-3480920-D1 (DE)
Inventor: SPERONELLO BARRY K
IPC: C04B38/04
Filed: 1984-06-19
Granted: 1990-02-08
Abstract: Clay convertible by thermal treatment into crystalline mulite and silica is formed into green coherent bodies of desired size and shape such as for example, microspheres, pellets or honeycombs. The bodies are then calcined to convert the clay into a mixture of crystalline mullite and silica, thereby also hardening the bodies. Without destroying the form of the bodies, e.g., without grinding and without causing the bodies to decrepitate, pores in the size range of about 150 to 350A are formed by selectively leaching silica from the bodies. The porous mullite bodies retain porosity at elevated temperatures and are useful, for example, as catalyst supports and contact materials. Pore structure in the meso- (100-600A diameter) and macro- (600-20,000A diameter) size ranges may be controlled.
