Title: Operating switch for electric tools
Inventor: MCCURRY RONALD C
IPC: H01H3/20
Filed: 1994-05-26
Abstract: An operating switch 25 for an electrically powered tool 10, consisting of a housing 16 and of an electric motor, which is supported by the housing 16, for driving a tool insert. The operating switch 25 has a trip device 22 which is arranged on the housing 16 and can be moved by the user between an "on" position and an "off" position. A mains switch assembly 26 is arranged inside the tool housing 16, adjacent to the trip device 22, and can be operated by the latter. The mains switch assembly 26 contains a moulding 28 which circumscribes an inner cavity 30 which has a cutout 32 which extends through said cavity 30. An electrical switch 34 is arranged inside the mains switch assembly 26 and is electrically connected to the electric motor. A bolt 42 extends through the cutout 32 in the moulding 28 and makes it possible to operate the electrical switch 34 by means of the trip device 22. An elastic foam cushion 44 is arranged between the bolt 42 and the trip device 22. The size and thickness of the foam part 44 are sufficient to close off the switch moulding 28 and to cover the cutout 32 when the trip device 22 is located in the "on" position in order to keep the electric tool live during normal operation, despite the tool vibrating, and to prevent dirt and machining residues (swarf) penetrating into the cavity 30 in the moulding of the ...

Patent DE-4420434-A1 (DE)
Title: Solar modulus prodn. for converting solar light to electricity
Inventor: KUSIAN WILHELM DR ING
IPC: B23K26/40
Filed: 1994-06-10
Abstract: The solar modulus is made by building up alternate layers of thin solar cell material (E2, E4) and TCO-electrode material (E1, E3, E5) on a transparent substrate (1). The solar cell material which may be pin- or nip-type is structured to interconnect them by using a laser beam. This produces solar cells within one layer with a parallel connection and solar cells in different layers with series connection. By focussing the laser beam on the bottom surface of the first solar cell material (semi-conductor), this material is blown off from the bottom electrode material and in the cases where other material is on top of this layer, such as material from layers (E3, E4, E5), this is removed at the same time.
Patent DE-4425133-A1 (DE)
Inventor: KUDRUS HEINER
IPC: B65H54/28
Filed: 1994-07-15
Abstract: In a winding machine with several winding heads, each winding head is equipped with a flyer thread guide with two rotors that rotate in opposite directions and have each at least two propeller-like flyers (13A, 13B, 14A, 14B). The winding heads (A, B) are arranged very close to each other, so that the circles of rotation of the flyers (13A, 13B, 14A, 14B) of adjacent winding heads (A, B) cross each other and only a narrow gap subsists between the thread-guiding areas (H) of adjacent winding heads (A, B). For that purpose, the rotor axes are arranged at an angle, so that the intersection lines between the planes of rotation (15A, 16A, 15B, 16B) on which the flyers (13A, 14A, 13B, 14B) rotate ascend at an acute angle. The planes of rotation (15A, 16A, 15B, 16B) of adjacent winding heads (A, B) overlap each other. The inclined position of the rotor axes further has the advantage that the towed length of thread, i.e. the length of thread between the end of the flyer and the point of contact of the thread with the contact roller, is the same at the point of reversal to which thread is supplied in each winding head (A, B) by flyers (13A, 13B) that rotate on lower planes of rotation (15A, 15B) and at the other reversal point, to which thread is supplied by flyers (14A, 14B) that rotate on upper planes of rotation (16A, 16B).

Title: Flash smelting apparatus and method for operating the same
Inventor: FUJITA MICHIRU
IPC: F27B14/06
Filed: 1994-10-06
Abstract: In addition to a first drive device which moves only one lower crucible and a first control device which controls the first drive device, a second drive device which changes the vertical relative position of an upper crucible and an induction coil, and a second control device which controls the second control device, are provided, making it possible for the relative positions of the upper and the lower crucible and of the induction coil to be freely varied. The relative positions of the induction coil and of the upper and lower crucible can therefore be suitably set over the entire operating duration, starting from the initial operating state up to the final operating state, in accordance with the position of a smelting zone in an upper region of a material to be smelted, which accumulates as a result of the continuous charging with chips.

Title: Cable tape winding machine is worked faster while maintaining quality
Inventor: SANDER JOERG
IPC: H01B13/08
Filed: 1994-10-14
Abstract: An appts. winds tape on an elongated product with one or more windings. The tape winder comprises a driven, rotating winding head, one or more tape rolls and, at the winding head, a stationary guide over which each tape is led. Here, one or more guides (4'), each to one tape (5), have one or more tapering contoured pieces (6) to produce increased tension in the edges of the winding tapes. Each contoured piece merges into a cylindrical part (7) to produce the tension in the edge region of the winding which is led over the piece.  Pref. the tapered contour piece is so placed that the tension produced during the winding procedure arises in the edge area opposing the cable passage direction. The cylindrical part can be located between two contoured pieces placed as mirror images one of the other and the distance between them is so adjusted that tension is produced in each of the two edge regions of the tape by its appropriate piece. The tapered contoured piece is a cone (4') which can also be formed with either a concave or a convex surface. It can be axially displaced but locked in place so as not to rotate on the cylindrical part of the guide and it plus the cylindrical part has a surface with low coefficient of friction or is free to rotate.

Title: Application of internal mineral coating to domestic water piping
Inventor: BRUEGEL ULRICH
IPC: B05D7/22
Filed: 1994-11-23
Abstract: The method for application of internal mineral coatings to domestic water piping is characterised by the fact that the cleaned piping is wetted with silicate solutions, and the damp film thus produced is hardened through acidification by means of carbon dioxide gas. Before acidification, the silicate film applied is subjected to intermediate drying by means of warm air. The process is repeated to influence the thickness and structure of the coating produced. Other gases or gas mixtures with acidification effects can be used besides carbon dioxide. Gases or gas mixtures emerging from the piping can be collected, compressed and used repeatedly in a circulation system.

Title: Procede et circuits de regulation du flux lumineux d'une diode laser
Inventor: OFENLOCH THOMAS PHILIPP JAKOB
IPC: H04N1/40
Filed: 1996-01-30
Abstract: Un procédé et des circuits servent à régler le flux lumineux d'une diode laser dans un organe optoélectronique d'enregistrement point par point ou ligne par ligne d'informations sur un support d'enregistrement. On détermine un écart de régulation (Δl) en comparant une valeur nominale du flux lumineux à une valeur réelle du flux lumineux. Un régulateur rapide (2) génère un courant de régulation (IR) en fonction de l'écart de régulation (Δl). Un régulateur lent (3) à mémorisation génère un courant de régulation du point d'application (IA) qui détermine le point d'application sur la courbe caractéristique de la diode laser. Ce courant de régulation du point d'application (IA) est additionné au courant de régulation (IR) pour donner le courant d'excitation (IT) de la diode laser (1). Les valeurs nominales du flux lumineux et le régulateur lent (3) sont utilisés pendant la période de mise sous tension de la diode laser (1) au début des périodes d'enregistrement et pendant les périodes préliminaires qui précèdent les périodes d'enregistrement. Le courant de régulation du point de fonctionnement (IA) corrige le point de fonctionnement de la diode laser (1) pendant les périodes préliminaires et reste constant pendant les périodes d'enregistrement qui suivent. Les oscillations éventuelles du flux lumineux (P) pendant les périodes d'enregistrement sont uniquement réglées par le régulateur rapide (2).
