Title: Synthetic filament spinning - using air-blast chambers under spinneret to create even cooling
Inventor: KRETSCHMANN HEINZ-WERNER
IPC: D01D5/092
Filed: 1991-02-09
Abstract: Multifilament synthetic is spun from a circular spinneret, and cooled in a current of air. Some of the minimal parameters for the air blast are produced from the shape of the perforated wall, the design and size of perforation, the air pressure, the number of filaments, and the length under the effect of the airblast.  The appts. is also claimed. The perforated wall is constructed in a semicircular shape, and the air passed through it is reflected by the straight back wall, so that the filament falling from the spinneret receives cool air all round. USE - To determine most advantageous design to obtain max. cooling of the filament at all positions.

Filed: 1991-03-27
Abstract: The known king roll reeling machines for shaftless winding of a web of material (4) divided by a lengthwise cut, in particular a web of paper of cardboard, onto sleeves (11) have take-up rollers (6) which are applied during take-up to two king rolls (2, 3) and are supported by guide heads (10) which can be inserted sideways into the sleeves of the two outer take-up rollers (6). The take-up rollers (6) can only be wound with high winding quality up to a maximum diameter. According to the invention, the space delimited by the king rolls (2, 3) and the take-up rollers (6) is sealed and an overpressure is produced in the space. To this end, sealing elements (18) which can be displaced axially to suit webs of different widths and which can be moved simultaneously in an area outside the area of movement of the guide heads (10) and their fastener (carriage (9)) are arranged in the region of the two side ends of the king rolls (2, 3). Frictional engagement between the king rolls is prevented when the sealing elements (15, 18) are in the sealing position.

Patent DE-4115686-A1 (DE)
Title: Thermal treatment of washing water from dye-penetrant crack detection - contaminated water is heated to breakdown emulsifiers etc. and separates by gravity into clean water with floating oily phase
Inventor: LEUCK KARL-HEINZ DIPL ING
IPC: G01N21/91
Filed: 1991-05-14
Abstract: In a procedure for treatment of washing water contaminated with coloured or fluorescent dye-penetrants, the water is thermally sepd. from the penetrants, and is recycled for further use. The structure of emulsifiers contained in the water is broken down by the thermal treatment, and the emulsifiers, stabilisers, tensides and other organic additives remain in the oily phase of the mixt.. This oily phase separates by gravity to form a floating layer above the water. After cooling, the clean water is drawn of from below. More specifically pump (1) delivers the contaminated water from the washing station of the crack-detection unit into the pretreatment vessel. Pump (3) delivers the cleaned water from the storage vessel to this washing station. A liq. level signal from the pretreatment vessel starts the thermal treatment process, pump (2) fills the thermal treatment vessel, and the heating is switched on for a period of time. After a suitable interval, the valve (1) opens and the sepd. water passes, via a heating coil in the pretreatment vessel, into the storage vessel. A turbidity meter senses when the floating oily phase reaches the treatment vessel outlet, and valve (1) closes while valve (2) opens and allows the oily liq. to flow into the final treatment vessel. After cooling, pump (4) returns any usable water from the final treatment vessel to the washing station, and the residual oily material is disposed of as waste oil. USE/ADVANTAGE - Used in quality control systems in which cracks in castings, etc. are detected by penetrating liqs. contg. dyes. The water used for removing these penetrants after completion of the tests is effectively treated without the use of consumable filtration materials which themselves need to be treated and/or dispersed of from time to time.
Patent DE-4117292-A1 (DE)
Title: Controlling washing procedure in washing machine - by taking into account effects of water jacket formation in spinning step of program
Inventor: HERDEN RUDOLF
IPC: D06F33/36
Filed: 1991-05-27
Abstract: A process is for controlling the washing procedure in a washing machine equipped with a speed-regulated drive motor for the drum. It involves determining the program cycle in accordance with a signal produced in the spinning program step. When a speed redn. not related to the program occurs in the spinning step because of water jacket formation, the additional program cycle is determined for the subsequent rinsing processes. The speed redn. is sensed by a device for the prodn. of the speed-related signal. ADVANTAGE - The process eliminates the negative effects of a water jacket as water jacket formation is taken into account in the subsequent program steps.

Inventor: CSIFFARI JOHANN
IPC: B29B17/02
Filed: 1991-09-03
Abstract: In the process, an old inflatable tyre is turned inside out and sections of the bead and/or carcass regions are cut away according to the final product. A hanging seat is produced by turning an old tyre inside out, cutting away and removing the carcass and tread area from the bead wires for up to 25% of the circumference.

Patent DE-4203413-A1 (DE)
Inventor: UHLEMANN VOLKER DIPL ING
IPC: H04N5/217
Filed: 1992-02-06
Abstract: The invention concerns a multiple-sampling process in which a noisy signal and the noise are each sampled N times and processed to give an output signal. In order to improve the signal and noise transmission characteristics, the invention calls for interlaced sampling of the signal and noise. Subsequently, either in the case of triple sampling, a total is calculated from the signal-sampling value and a noise-sampling value,less an additional double noise-sampling value, and the output signal representing the sum of the totals is generated, or the differences between each signal-sampling value and noise-sampling value are calculated, and the output signal calculated from the sum of the differences.

IPC: F16H57/02
Filed: 1992-02-18
Abstract: A bonded joint disclosed between two toothed wheels (1, 2) and a shaft (3). The sum of the bonding surface areas (K1, K2) is greater than the direct contact surface area between the shaft (3) and at least one toothed wheel (1 or 2).

Title: Curved glass pane transfer - has upwards stream of air to press pane against holder while moving from the intermediate station to the transfer station
Inventor: BADOT MARCEL
IPC: C03B35/20
Filed: 1992-07-21
Abstract: To transfer one or more curved glass panes from a precurving station to a roller conveyor, while they are horizontal, in the intermediate station they are pressed against a holder by an upwards air current. The holder travels horizontally between the intermediate station and the transfer station, to carry the glass material to transfer it to the conveyor while the upwards air stream is maintained at the intermediate station and through to the transfer point. The holder is a slide moving horizontally on rails, with its own drive, to travel between an end point at the intermediate station and an end position at the transfer station. USE/ADVANTAGE - The system is for the transfer of horizontal precurved glass panes to a roller conveyor. The operation prevents any damage to the surface of the glass pane from splinters of broken glass.

Title: Method of slicing foodstuffs, eg. bread - involves loaf end clamp with claw and spikes automatically withdrawing as end crust approaches cutter, and allowing access for cutter to slice loaf completely
Inventor: SCHMIDT UWE DIPL ING
IPC: B26D7/01
Filed: 1992-09-12
Abstract: As the clamped end of the loaf approaches the cutter (12) an ejector bar (11) comes up against a stop pin (13) and causes the claw (2) and spikes (3) automatically to swing out of engagement. This leaves the loaf supported only against the endplate (17) and allowing access for the cutter to slice the loaf completely. When the clamp returns to the unengaged position, the last slice lies in the vicinity of the cutter. USE/ADVANTAGE - Bread slicing machine avoids need for hazardous removal of end crust from clamp by hand and reduces packaging cost. Improved efficiency and profitability of slicing process.
