Title: Exhaust gas purification method using catalytic converter, esp. for cold start - using fuel fired burner to preheat catalytic converter, controlled by temperature sensors
Inventor: HAERTEL GUENTER
IPC: F01N9/00
Filed: 1991-10-02
Abstract: The purification method is employed in an exhaust system where  a burner (14) is fitted before the catalytic converter. Temperature sensors in the catalytic converter and a controller (6) operate the burner if the temperature is below a set level, and switch off the burner above a higher set level.

Title: Industrial sewing machine - utilises measurement of the length of article before automatically transferring to rail.
Inventor: KOEHLER DIETMAR
IPC: D05B41/00
Filed: 1991-11-21
Abstract: Process is to automatically transfer varied length sewn articles to a pile on the rail, from an industrial sewing machine which has transfer facilities. There are two sensors between the needle and the transfer mechanism. Three stages are involved in the process. Firstly, the first sensor and counter recognises the begining of the articles.

Thirdly, the transfer mechanism operates in a manner suitable for the length of the article. ADVANTAGE - The operator does not need to pay attention to length, making special prepn. for long articles. The long articles do not drag on the floor and the short articles do not become crumpled in the pile.

IPC: C03B19/10
Filed: 1992-01-14
Abstract: Proposed is a process and device for the manufacture of glass beads by solidifying molten glass whose transformation point lies at a temperature or in a temperature range TG. In order to ensure high quality with respect to the bead shape and to ensure a narrow bead-size distribution, the invention calls for the molten glass to be stressed thermally or chemically, the solidified glass to be broken into pieces and the pieces of glass to be melted and to travel unconstrained along a path of length such that the surface tension of the molten pieces of glass causes them to turn into glass beads, which are subsequently cooled.

Title: Mfg. rotationally symmetric metal components used as ring rolling blanks - in which material is applied directly on cylindrical surface, rotating carrier by spray and/or sprinkle nozzles
Inventor: FRIEDRICH RAINER N R PROF DR I
IPC: C23C4/18
Filed: 1992-03-13
Abstract: Prodn. is claimed of rotationally symmetric components - made of materials (in particular, metals) which can be cast, moulded or formed - serving as ring rolling blanks for ring rolling mills.

Patent DE-4304511-A1 (DE)
Inventor: GLATZ DIETMAR
IPC: A47L9/28
Filed: 1993-02-15
Abstract: The vacuum nozzle of the invention consists of a housing which is open at the floor side and in which a brush roller which is provided with brushes and can be driven by an electric motor is arranged. The speed of revolution of the brush roller can be controlled as a function of different suction parameters, the speed of revolution of the brush roller being detected indirectly or directly by at least one sensor and the signal of the sensor being converted in an electronic evaluation unit. This evaluation unit in turn supplies a control variable for the electric motor which drives the brush roller. In order to reduce the sensitivity to contamination of the sensing of the speed of revolution and thus of the control system, the sensor consists of an electro-acoustic sensor which is arranged in the region of at least one source, in particular in the region of the brush roller, which emits a noise which is dependent on the speed of revolution and/or load, in or on the housing of the vacuum nozzle.

Patent DE-4316533-A1 (DE)
Title: Neural network for dynamic processes
Inventor: KROGMANN UWE
IPC: G06N3/08
Filed: 1993-05-18
Abstract: The invention concerns a neural network with a layer of processor elements, in which network input magnitudes which are switched to one input of the network are switched to each processor element with weights depending on an input matrix (G). Each processor element has an activity which depends on a sum of weighted input magnitudes, and supplies an output magnitude which is a function of the activity. The output magnitudes of the processor elements are superimposed, weighted depending on an output matrix (H), to form output magnitudes of the network at an output. The input magnitudes of the network are switched to the input clocked at a specified clock rate. Also, weighted output magnitudes of all processor elements are applied to the input of each processor element. The activities of the processor elements in a clock cycle (k + 1) are specified by the weighted input magnitudes and weighted output magnitudes in the previous clock cycle (k). <IMAGE>

Title: Device for drawing ellipses
Inventor: KNAUF PETER
IPC: B43L11/055
Filed: 1993-06-07
Abstract: The device has a first and a second leg (1, 9), the first of which carries a point (19) at its lower end, whilst a second is provided at its lower end with a pencil (27). The latter terminates level with the point. The second leg is rotatably connected to the first leg and is adjustable relative to the latter, specifically in a direction perpendicular to the axis of the first leg. The latter carries a disc (11) having a circular circumferential edge (23) and tiltable about an axis (13) which is defined by a diameter of the circumferential edge and which extends perpendicularly to the axis of the first leg. The second leg engages under spring pretension on the circumferential edge of the disc by means of a tracer. When the disc is tilted and the second leg is rotated about the first leg, the pencil describes the contour of an ellipse, the axial ratio of which depends on the tilting angle of the disc. The size of the ellipse is determined by the spacing between the tracer and the pencil. <IMAGE>

Title: Winding apparatus for light waveguides
Inventor: CHRISTIANSEN WERNER
IPC: G02B6/44
Filed: 1993-06-24
Abstract: The present invention relates to a winding apparatus 3 for light waveguides, especially glass-fibre cables 10. The winding apparatus 3 consists at least of a baseplate 1 and two winding reels 4, 5 which are arranged on the baseplate 1. The winding reels 4, 5 have preferably a round cross-section with a diameter which prevents an excessive bending of the glass-fibre cable 10. One winding reel 4 serves as a loop holder for the glass-fibre cable 10; the other winding reel 5 serves for receiving the excess length of the glass-fibre cable 10. This ensures that the glass-fibre cable 10 can be wound without twisting. A further essential advantage of the present invention is that the glass-fibre cable 10 can, according to the invention, be wound without separation from the system. Moreover, the winding apparatus is simple in terms of production and operation.
