Patent DE-3339862-A1 (DE)
Title: Process for mercerising unbleached fabric or treating it with alkali
Inventor: GOTTSCHALK KARL-HEINZ DIPL ING
IPC: D06B7/02
Filed: 1983-11-04
Abstract: The invention relates to a process for mercerising unbleached cotton fabric or blends thereof with polyester fibres or treating them with alkali as a pretreatment for a subsequent bleaching process or the like, and to an installation for carrying out the process, and aims to achieve a simplification in the pretreatment of the fabric before the bleaching or dyeing. In particular, desizing and boiling off should be combined with the mercerisation to give an overall process, by means of which not only a significant simplification in the pretreatment of fabric, but also a cost saving, in particular in the apparatus cost, results. To this end it is proposed first to impregnate the fabric with mercerisation liquor at a temperature of about 20-40 DEG C, after this to expose the fabric to a swelling process in air for a period of about 30 sec., then to subject the fabric in a broadly stretched state to a drying treatment down to a residual moisture content of about 30% and thereafter to carry out washing-out of the fabric at a temperature of about 95-100 DEG C for a period of at least 30 sec. After this, the fabric can be cooled in a known manner and then bleached in a customary manner.

Patent DE-3341514-A1 (DE)
Title: Wind fan generator
Inventor: PUHANE PAUL
IPC: F03D9/32
Filed: 1983-11-17
Abstract: Organic fuels and the environmental pollution associated therewith in the operation of land, water and air vehicles are avoided by the use of a wind fan generator. This is achieved in that the wind fan blades fitted on the vehicle are set in motion by the airstream and current thereby generated by way of a generator, with which current the batteries required for electrical operation are charged and recharged. In order to ensure this effect even at slow speeds of travel and in the event of stoppages due to traffic, a connectable fuel current generator is installed in the vehicles and furthermore additional charging of the batteries is undertaken by a mechanical, additionally connectable wheel drive generator.

Title: Galette
Inventor: KUEMMERLE WERNER ING GRAD
IPC: D02J13/00
Filed: 1983-11-19
Abstract: Cooling air flowing in the direction of the arrow (52) flows round the bearing (16) of the galette shaft (10.2) of a galette (1.3). The cooling air enters from the driving side a cavity (37.2) of the galette shaft (10.2) which leads into the vicinity of the bearing (16) and passes through air throughflow ports (38.2) around the bearing (16) into an interspace (45) and from there, conveyed by a ring of fan blades (49) fastened to the galette (1.3), through ports (53) in the machine stand (12) into the open. The transfer of heat through the galette shaft (10.2) in the direction of its drive is avoided, and impairment of the heating device (25) of the galette by cooling air is prevented by a protective heat shield (51). <IMAGE>

Title: Vibratory tamper
Inventor: LATT WILHELM
IPC: E02D3/046
Filed: 1984-10-29
Abstract: The stroke and tamping movements of vibratory tampers are considerably dampened by the oil used for lubrication and by built-in springs.

Title: Process for the direct reduction of iron oxide-containing materials in a rotary kiln
Inventor: SERBENT HARRY DR
IPC: C21B13/08
Filed: 1985-03-16
Abstract: For the direct reduction of iron oxide-containing materials to give iron sponge, the rotary kiln is charged with the solid materials and an agglomerated solid carbonaceous reducing agent. Distributed over the length of the rotary kiln, oxygen-containing gases are blown in and at least a part of the solid carbonaceous material is burned. To obtain high throughputs with the lowest possible maximum temperature while producing an iron sponge of low sulphur content, using a carbonaceous reducing agent of low reactivity, such reducing agents in pelletising fineness are agglomerated with added water, the agglomerated carbonaceous material is charged at the charging end of the rotary kiln and passed in an agglomerated form through the heating-up zone to the reaction zone, and limestone or raw dolomite is charged separately to the kiln.

Title: Bogie and rail vehicle and method for providing emergency support
IPC: B61F5/14
Filed: 1985-03-22
Abstract: An emergency support for the wagon body (1) of a rail vehicle is to be provided, which rail vehicle is equipped with bogies (5) which have pneumatic suspension (3) whose pneumatic chambers are connected to one another by means of a compensation line (2) and the pneumatic springs (3), of a bogie (5), which are connected to one another are controlled in a load-dependent fashion and, in order to stabilise the rolling movements of the wagon body (1), are equipped with an anti-roll support (9) arranged between wagon body (1) and bogie frame (4).

Patent DE-3541201-A1 (DE)
Title: Device for oscillation damping
Inventor: EGELHOF DIETER
IPC: D21F1/06
Filed: 1985-11-21
Abstract: In the case of the device, a unit which produces opposing oscillations which are phase-shifted with respect to the pulsations is connected to the length of line which follows downstream of the installation parts which excite the flow oscillations, which unit is frequency-controlled and amplitude-controlled as a function of the oscillation pulses of the length of line. As a result of the fact that a further pulse sensor (10) is connected to the length of line (14), at a specific distance from the first pulse sensor (1) and between the installation parts which excite the flow oscillations and the unit which produces the opposing oscillations, in order to form a propagation time correction signal in conjunction with the signal of the first pulse sensor (1), the compensation of the oscillations is improved. <IMAGE>
