Inventor: SCHARP RAINER
IPC: F02F3/22
Filed: 2003-09-24
Abstract: Disclosed is a multipart, cooled piston (1) for an internal combustion engine, comprising a top part (2) and a bottom part (6) which are screwed together via a threaded bolt (26) that is disposed on the top part (2) of the piston and a threaded bore (29) that is incorporated into the bottom part (6) thereof.

These casings are ignited reliably and rapidly, and burn much faster than the known materials of this type.
Patent DE-2033810-A1 (DE)
Title: Flat-face rope-uses corner strip filler on square core to shape - the rope faces together with downstream press jaws
IPC: D07B7/02
Filed: 1970-07-08
Abstract: Fillers as filament, wires, strands etc. are placed on the corners of a rectangular or square moving core member so that the wires in the layers bend over the corner fillers and thus adapt themselves to the shape of the core. Either the strands are twisted in halves at two successive stranding points, or the core is fed into a truncated pyramid guide through a hollow shaft, using the pyramid faces to guide the wires forming the rope ahead of the press jaws which form the rope. Flat face ropes adapt better to winding sheaves or pulleys and spread the high wear factor thus extending service life.

Patent DE-2156269-A1 (DE)
Title: Ring rolling mill with tiltable roll axis - avoids conicity in finished ring
Inventor: JEUKEN JOSEF
IPC: B21H1/06
Filed: 1971-11-12
Abstract: Tendencies for conicity in the cross section of a finished rolled ring are eliminated by tilting the axis of the main roll spindle in a plane that lies vertical to both the plane of the mandrel spindle and the direction of rolling. The tilting is achieved by movement of the top roll bearing in this plane by means of wedges locked in position by bolts. There is no necessity to turn the ring over during rolling in order to even out the taper, and subsequent time is saved.

Title: Suspended mine monorail track - has traction cable flange roller with shallow concave arching on cable running surface
IPC: B61B12/02
Filed: 1971-04-29
Abstract: On a monorail track of the suspension or above-rail type, as used in mining for personnel or material transport, the flange roller is for guidance of a traction cable, in a roller opening formed by a number of flange rollers, with a gap opening for the passage of a cable arm. A cable running surface is formed on the flange rollers, with curved crossovers into the flanges. The cable running surface (71) is flatly concave arched over most of the flange roller (70) width (B). The curved crossovers (73) are short and sharply curved. The roller flanges (75) have cut-away edges (77). This makes it possible to provide a traction cable roller opening where sufficiently strong closure forces are applied to the gap, in spite of the presence of relatively weak closing springs.

Title: Mileage recorder for compulsory vehicle maintenance - is extra toothed wheel on number roll to actuate preset continuous warning
Inventor: SCHLICK HORST
IPC: F02B77/08
Filed: 1973-07-14
Abstract: The mileage recorder consists of six number rollers mounted on a shaft and a second shaft carrying the decimal switch wheels which are turned in the usual way by a single tooth on the number roll. A third shaft carries a toothed wheel turned by the tens roll so that every 100 kilometers it is turned by one tooth. The shaft motion is transmitted via a slip clutch to a wheel provided with an outer spiral groove. A spring strip whose one end is fixed to the recorder housing carries a projection which slides in the spiral groove. The other spring strip end forms an electric contact with a fixed contact insulated to the recorder housing.

Title: Electric fan wall heater - has air flow downward through housing, and regulator in branched air stream, in upper part of housing
Inventor: KAISER HELMUT
IPC: G05D23/275
Filed: 1973-11-23
Abstract: Electric, wall convector heater has a fan and temp. regulator; the air openings are in the upper (entry) and lower (outlet) parts of the fan respectively, and the fan air stream is passed over heating elements. The regulator is in a partial air stream diverted from the hot air channel in the upper part of the housing. Preferably the regulator is in a side channel in the housing, connected with the hot air outlet channel by a bypass, which is dimensioned so that a rise of temp. of 15 deg. results. Switching off of the fan does not result in an incorrect high reading of the regulator.
Patent DE-2362855-A1 (DE)
Title: Digital PCM signal transmission with interrepeators - uses signals time division and subsequent signal sections compression by given factor
Inventor: MARTIN HELMUT DR ING
IPC: H04L5/14
Filed: 1973-12-18
Abstract: The PCM signal transmission uses intermediate repeaters incorporated into the telecommunications cable cover between the transmitter and receiver. The digital signals are at first split in time sections and subsequently compressed by a factor greater than two with respect to their initial frame length. The signal sections in both transmission directions are so transmitted over the same wires that they run simultaneously over different transmission sections, and are stored in the repeater sides facing the receiver in separate stores. Then by switching over the stores the signal sections are transmitted separately to the repeater sides facing the transmitter.
Patent DE-2400456-A1 (DE)
Title: Peristaltic pump for liquid bitumen - has phase displaced rollers on adjustable arms and pump hose actuating pads
Inventor: BENNINGHOVEN ERICH
IPC: F04B43/12
Filed: 1974-01-05
Abstract: The peristaltic pump used especially for pumping of liquid bitumen, has a flexible pump hose placed on a flat horizontal bed and is flattened by two pressing rollers which are arranged at the ends of rotating levers. Owing to the phase angle of 180 deg. the flexible hose is squeezed against the baseplate, and the material within the hose is pumped in batches. The hose is placed on the plate and is squeezed by the rollers which do not act directly on the hose but they exert pressure on the curved plate which are suspended with helical springs. The actuating rollers are held on the ends of double arm levers which are rotated about central spindles. The pads ensure that the pressure applied by the rollers is spread over a greater area and this increases the lift of the flexible hose. The performance is improved by loading the rollers by springs within the slots of the lever arms and this ensures that the suspension spring force of the pads does not reduce the load applied by the rollers.
