Patent WO-03004811-A1 (WO)
Inventor: HUBERT HARTMUT E
IPC: E05B67/06
Filed: 2002-04-15
Abstract: U-locks and air pumps for bicycles are generally known and have been marketed for decades. Locks and pumps are the only portable parts of a bicycle. The U-lock (with a fixed mounting on the bicycle) has become increasingly successful as the optimal security item for the bicycle, whereas the pump with a fixed mounting on the bicycle has not enjoyed as much success. The inventive U-lock consists of a bow and two straight parts, whose ends terminate in a lock. One straight part is configured as a pump with a reinforced casing so that the normal function of the U-lock is maintained. To use the pump, the U-lock is detached from its mounting, thus releasing the handle of the pump. The latter can be produced as a standard, telescopic or compressed air pump. Said pump comprising an integrated pump is primarily designed for bicycles but can also be used for motorcycles or similar.

Said device comprises a furnace that accommodates and heats the pipes, with or without associated cooling zone, and a gas guiding device (15, 16) for feeding a scavenging gas to or removing it from the pipes. Said gas guiding device is provided with means for detachably and sealingly establish a link with a gas feed line and a gas discharge line. The aim of the invention is to configure the link with the pipes in as easy and reliable a manner as possible. For this purpose, the device is configured in such a manner that both ends of every pipe are separately connected to one and the same connecting head (4) that has a gas inlet (5) and a gas outlet opening (6) axially aligned therewith. The end (7) of the gas feed line and the end (8) of the gas discharge line are opposite each other and can be displaced along with the gas inlet opening and/or the gas outlet opening while sealingly connected.

Title: Dosing mixing and supplying synthetic resin component - - with control of stirrer performance and speed
Inventor: HEIMBURG HENNING VON DIPL ING
IPC: B29B7/60
Filed: 1971-11-30
Abstract: The arrangement has a hydraulic cylinder to drive pumps, a hydraulic stirrer motor and oil pump to drive it, and a further oil pump to drive the cylinder. The outlet side of the hydraulic cylinder is connected to the stirrer motor so that when the piston moves and the pumps start, considerable quantities of high pressure oil move from the cylinder to the stirrer motor. The quickly the cylinder and pumps operate, the more the stirrer motor is activated. The stirrer motor has only a small capacity pump. Oil from the cylinder provides accurate time control of the performance and speed of the stirrer according to throughput.

Title: Log shredder - through centreless grinding with alternate compression - and relaxing movements to concentrate shredding action
Inventor: BERSANO PIERO DR
IPC: D21B1/06
Filed: 1972-01-31
Abstract: The shredding action to reduce a log to wood pulp uses a serrated shredding roller in conjunction with two control rollers and a free-spinning roller together with sprays. The control rollers and the free-spinning roller exert an alternate compression and relaxing action on the log as it is turned and held against the shredding roller while the surface is reduced to individual fibres and the diameter of the log becomes smaller.

Title: Sliding surface made separately from machine part - with flat bearing face and lubricating recesses
Inventor: SCHMIDT HANS
IPC: F16C33/20
Filed: 1973-05-11
Abstract: A sliding surface for a machine component, where a sliding facing is separately produced and then glued onto the component, is made by manufacturing the sliding facing, along with lubricating pockets and bearing regions situated in a clearly defined plane. In one prefd. method, the lubricating pockets and the supporting regions (i.e. raised areas) are formed in a pressing mould which itself is produced from a master template having a precision machined surface from which the lubricating pockets have been hollowed out. In another method, the pressing mould is formed with a precision machined surface where the regions corresponding to the lubricating pockets are thickened by electrolytic coating. In yet another method, the sliding facing is produced by rolling between a pair of rolls, one of which has the desired negative surface formation.

Title: Liquid and gaseous low-sulphur fuels prodn. - by hydrogenation of solid fuels and purification of resulting gases
Inventor: GERNHARDT PAUL DIPL PHYS DR
IPC: C10J3/64
Filed: 1973-05-29
Abstract: Hydrogenation of solid fuels is improved in that a solid residue remaining after the release of the hydrogenation products from the liquid phase is subjected to a special gasification process to produce additional hydrogen. The gases obtained by this gasification process can be combined with gases from the partial oxidation stage and jointly subjected to the operations of sulphur-scrubbing, conversion of CO into CO2, and removal of the latter. By this method, the hydrogen economy is improved. Sulphur cpds. removed from the fuel can be utilised elsewhere.

Title: Spring drive for film transport and squeeze rollers on a camera - has a manual ratchet spring tensioner and cam controlled film pusher
Inventor: BRAEUNING GERHARD
IPC: G03D9/02
Filed: 1973-08-06
Abstract: The operating spring is coiled around a spindle between two cogs. The spring ends are engaged by stops on the inner aspects of the cogs. One cog is fitted with a winding handle and reverse stop. The other cog is fitted at one end of one of a pair of squeeze rollers. A double armed pivoted and spring loaded escapement lever is coupled to the cog stops to ensure a regular unwinding movement. The inner cog is fitted with a cam curve. A pivoted lever is spring loaded so that one end bears against the curve. The other lever end carries a hook which engages a film perforation and moves the exposed film at an even speed through the squeeze roller pair as these rotate. The design is claimed to be space and cost saving and effective in spreading the processing chemicals evenly over the exposed film.
