Title: Catheter for male urethra to drain bladder - permits flushing of natural urethra with contents bladder to prevent blockage due to disuse
Inventor: ZEIDLER MARTIN DR MED
IPC: A61M25/04
Filed: 1974-10-25
Abstract: The catheter has one or more outlet perforations arranged so that the contents of the bladder in the distal urethra are released again into the natural urethra. Pref. a conical stopper is integrated into a self-locking device which can be externally operated by a central body equipped with a knob, spring and counter stop. Retention of the natural flushing of the urethra helps to prevent infection and resultant scar tissue occurring from use of catheter. The catheter has a short flow through section D with a rubber-like stopper head (V) ending in a central body. The central body extends into a casing (C) ending in a wide based guide plate (G) which has a spiral spring (F) connected to it continuously pushing the end knob away from guide plate (G).

Title: Alkyl adamantanes from adamantanes and olefins - in the presence of a free radical initiator
Inventor: TABUSHI IWAO
IPC: C07C2/54
Filed: 1974-11-05
Abstract: A process for producing an alkyl adamantane comprises reacting an adamantane cpd. with an olefin in the presence of a free radical initiator. When ethylene or propylene is used as 1-1 adduct and a prod. with a longer chain alkyl gp. are formed, the latter due to telomerisation, but with other olefins a 1-1 adduct, is obtd. almost exclusively. Generally reaction temps. fo 60-150 degrees C and reaction times of 1-5 hrs. are satisfactory. The prods. may be used as inters. for org. syntheses e.g. 1-n-hexyl or 1-n-octyladamantane is used for synthesis of carboxylic acids which are useful as oil additives, and their alkaline earth metal salts are useful as anti-rust agents; also alkyl adamantanes, can be oxidised to adamantanol which on esterification with phosphoric or sulphuric acid produces a hydraulic oil. Further, alkyl adamantanes themselves may be used as lubricants and their derivs. as insecticides and influenza medicines.

Title: Two stroke engine - has crankshaft turning on planet gear to give compression and power strokes
Inventor: VIGENER GUENTER
IPC: F01B9/00
Filed: 1975-01-04
Abstract: The two stroke engine crankshaft runs in a planet gear and the piston consists of a disc with a piston ring and screwed onto a solid or tubular connecting rod. The cylinder at the lower end has openings regulated by the piston movement to suck in pure air via one way valves as the piston rises and compress the air into the crankcase as the piston descends. A transfer channel is cast in the engine block to enable to crankcase air to enter the combustion chamber. A labyrinth seal is provided between the crankcase and the cylinder base which allows an alternating depression and compression in a pre compression chamber to occur without drawing oil from the bearings.

Title: Heat engine giving pollution free conversion - uses solar or atomic energy stored in rocks to produce mechanical energy
Inventor: NEUMANN ERHARD
IPC: F01K23/02
Filed: 1975-01-09
Abstract: The heat engine has continuous controllable combustion and two integral, thermally coupled circuits, with corresponding working mediums. The second circuit consists of an auxiliary circuit, controlled and switched by a compressor valve and a relief nozzle, with a residual heat utiliser, with high- and low pressure branches. The pressure, is above those of the high pressure branch of the first circuit, so that the first working medium evaporates and the second working medium condenses. The evaporated first medium is supplied via a super heater to the motor, while the condensed second medium, flowing in the opposite direction, is relieved, and cooled further, thereby causing the condensation of the working medium in the low pressure circuit, with reversed pressure and temperature conditions. During this process, the second working medium evaporates and is compressed, after passing the residual heat heater.

Title: Safety vent cap for lead-acid vehicle batteries - has three vent caps ganged and mounted on single cover, provides flame barrier
Inventor: GRABB NICHOLAS GEORGE
IPC: H01M2/12
Filed: 1975-05-23
Abstract: The vent cap has a cup shaped body which fits into the vent holes, and within the cup shaped body, near the bottom, is a disc of open pored rigid material such as a ceramic or a porous thermoplastic material. Gas flow through the vent cap is permitted, with gas entering the interior of the vent cap below the disc and emerging from a gas passageway at the top of the body near the cover. A post extends down from the cover into the interior of the body of the vent cap. Electrolyte which may be in the gas as it passes through the porous disc condenses on the post and falls back onto the disc and thence through it to be returned to the battery cell. The disc impedes the outflow of electrolyte in the event of upset of the battery.

Title: Centrifugal separator for fruit and vegetable juices - filter foil surface forms secondary filter with centrifugal bowl
Inventor: YAMAOKA MIKIO
IPC: B04B3/00
Filed: 1975-10-17
Abstract: A technique for sepg. a fluid from a mash by applying a centrifugal force, rotates the mash inside a perforated foil which can be compressed radially, as it turns around the axis, so that the fluid is led radially outwards. The radially outwards motion of the fluid is limited by a wall surface enclosing the foil concentrically so that a pressure of fluid is built up between the foil and the enclosing surface. This pressure compresses the foil with the formation between the outer surface of the foil and the inner surface of the surrounding wall, of a narrow cylindrical gap. As a result, the fluid in the gap under the existing pressure flows parallel to the vertical axis of rotation and is able to escape outwards. Yields a juice without sediments of solid or fibrous matter. The filter cannot become choked and is very easily cleaned by rinsing in water.
