Title: Low friction type bearing in compressed air operated disc brake system - has relevant face subjected to high pressure which is e.g. mainly PVDF with small PTFE and lead contents
Inventor: BAUMGARTNER HANS
IPC: F16D65/14
Filed: 1992-04-13
Abstract: Disc brake has a casing round the disc with a tensioning device at one side with tensioning device have an arm in a semi-circular bearing on the side further from the disc. Bearing allows turning round an axis which is parallel to the plane of the disc. At the side nearer to the disc the arm rests against a beam through an approx. centre eccentric; the beam is parallel to the axis and can be moved relative to the disc; by means of at least one pressure member it can act on a brake jaw to move it relative to the disc, the jaw being also inside the casing. Another bearing is between the eccentric and beam and/or the eccentric and arm. At least one of the bearings is a friction type, of which the low friction pressurised face is at least 70 vol.% PVdF, at least 10 vol.% PTFE and the rest is lead. ADVANTAGE - Compressed air-operated disc braking system is inexpensive to produce and to fit, and provides a uniformly efficient braking hysteresis.

Patent DE-4214604-A1 (DE)
Inventor: EMRICH HELMUT
IPC: B65H29/04
Filed: 1992-05-08
Abstract: The invention relates to a device for conveying sheets in a printing machine, in which the sheets are conveyed by gripper carriages which are linked to endless chains driven by chain wheels, and in which a transfer of the sheets takes place between the gripper carriages and the sheet-conveying cylinders in the region of the chain wheels. A transfer drum of this type is to be designed in such a way that a freshly printed sheet or a sheet provided with a varnish coating can be transferred to the sheet-conveying cylinder without smearing and can be transferred from said cylinder without smearing. The chain wheels (8) around which the chains (7) are guided do not have a continuous shaft, but are mounted in each case at one end of a shaft stub (11), which stubs are each mounted rotatably in a side-frame wall of the printing machine. Mounted in each case at the other end of the shaft stubs is a gearwheel (12) which meshes, for example, in each case with a gearwheel (13) mounted on both journals of the sheet-conveying cylinder (1). Consequently, the synchronising of the pair of chain wheels does not take place by a continuous shaft, but in each case via a pair of gearwheels, for example of the sheet-conveying cylinder. <IMAGE>

Title: Ultrasonic testing method for locating material defects - driving ultrasonic transducer with FM chirp signal with instantaneous frequency variation matched to transmission path transfer function
Inventor: BERNUS LUDWIG VON DIPL ING DR
IPC: G01S7/52
Filed: 1992-09-25
Abstract: An ultrasonic transducer arranged in a transmission path is driven by a frequency modulated chirp signal whose instantaneous frequency is non-linearly modulated with time.

The chirp signal frequency variation is correlated with the corresp. frequency of the transmission path transfer function so that the rate of frequency change is lower for frequencies with a lower corresp. value of the transfer function than for frequencies with a higher corresp. value. USE/ADVANTAGE - E.g. for locating material defects. High time resolution over large range.

Title: Reducing iron@-contg. material - using reducing gas under pressure in several fluidised bed reactors
Inventor: ROSE FRITZ DR
IPC: C01B3/36
Filed: 1992-10-02
Abstract: Method of reducing finely dispersed iron oxide-contg. material consists of producing a reducing gas by cracking hydrocarbons in vapour form in an almost stoichiometric amount. The reducing gas is mixed with circulation gas which is already heated and used to fluidise the beds in the reactors. The gas leaving the last bed is passed through a washer-cooler unit to remove dust and H2O and then through a CO2 washer to remove CO2 before being recirculated as the circulation gas. ADVANTAGE - A high degree of reduction is achieved without any prior treatment of the material. The method is effective and economical with the amount of energy used.
