Patent CH-680986-A5 (CH)
Title: Cleaning contaminated air from grinding of polishing equipment - includes passing air through duct into which moistened air is tangentially injected, feeding to vertical centrifuge and then washing vessel, etc.
Inventor: L INVENTORE HA RINUNCIATO AD E
IPC: B01D50/00
Filed: 1990-12-27
Abstract: Contaminated air is passed through a duct into which moistened air is injected tangentially to produce a swirling action. The air enters a vertical centrifuge where solid material is deposited at the bottom, the partly cleaned being removed through a vertical pipe to enter a vertical washing vessel contg. a structure of pockets. Clean air is extracted at the top by a duct connected to a suction unit and liquid falls to the base to pass to a microfilter, the fine solid material being discharged into a collector. At the tangential spray zone at the inlet duct, the air temp. and saturation are regulated by a control system. The process is interrupted to prevent explosion. USE/ADVANTAGE - Used to clean contaminated air from grinding or polishing equipment.
Patent CH-632080-A5 (CH)
Title: Heat pump installation
Inventor: LEDERMANN HUGO
IPC: F25B30/02
Filed: 1978-05-18
Abstract: In the heat pump installation, the sensible heat of the evaporated refrigerant is transmitted in a separate desuperheater (3) to the heat carrier, for example heating water. The latent heat is made use of, quite separately from the latter, in the condenser (4) arranged downstream of the desuperheater. Thus, the heat carrier can be conveyed in separate circuits via the desuperheater and via the condenser. The heat obtained in the desuperheater can be fed to a storage container (6) and from here, when required, to the room heater, for example. The latter heat is at all times conveyed via the condenser, but only optionally via the desuperheater. The sensible heat can in this way be used in an efficient manner. If required, specific heating can be carried out. The heating water can be heated to a level lying substantially above the condensation temperature (of the refrigerant), substantially hotter water from the storage container (6) being admixed with the heating water conveyed via the condenser. <IMAGE>

Title: Optical telescope with an aiming marker device
Inventor: KATOWSKI OLAF
IPC: G02B27/32
Filed: 1983-11-23
Abstract: The telescope is provided with two mutually perpendicular rotation axes (K-K, V-V) and an optical axis (Z-Z) perpendicular to one rotation axis (K-K). The optical axis (Z-Z) is perpendicular to the rotation axis (K-K) and the latter is perpendicular to the rotation axis (V-V). Rotation about the rotation axis (K-K) pivots the optical axis (Z-Z) in that plane which also contains the rotation axis (V-V). An aiming marker carrier is arranged at least approximately in a vertical plane which contains the other rotation axis (V-V) as well as the optical axis (Z-Z). An aiming marker (Zi) mounted on the aiming marker carrier is arranged on the optical axis (Z-Z). The virtual image (Zi') of the aiming marker (Zi) is preferably situated at the common point of intersection of the optical axis (Z-Z) and the rotation axes (K-K, V-V) when viewing the aiming marker (Zi) from outside through the telescope lens. The aiming marker carrier can be constructed to be transparent and the aiming marker to be less light-transmitting, or the aiming marker can be constructed to be transparent and the aiming marker carrier to be less light-transmitting. The aiming marker carrier can be mounted fixed on the telescope or in a pivoting fashion in the telescope. The aiming marker can be illuminated by illuminating devices. The device facilitates the alignment of devices with one another by means of telescopes mounted thereon. The telescopes are orientated relative to one another after in each case sighting once with both instruments in both positions and setting the position determined. <IMAGE>

Patent CH-625848-A5 (CH)
Inventor: PANETTI ROMOLO
IPC: E01B31/17
Filed: 1979-12-31
Abstract: Device intended to be displaced along track rails and comprising a frame (2) guided by the rail (1) provided with a grinding wheel (6) which grinds through its periphery. To uniformly distribute the wear resulting from contact with the rail on all its active surface, the grinding wheel (6) is driven, in addition to the continuous rotation supplied by a driving motor (7), in an alternating motion transverse to the track by means of an actuating mechanism. This actuating mechanism comprises a motor-gear assembly (13) driving an eccentric shaft (9) on the eccentric of which the movable support (8) is hinged. To avoid the formation of sinusoidal traces due to the grinding, the amplitude a of the reciprocal movement is related by the equation a SIMILAR l-f to the width l of the active surface of the grinding wheel and to the width f of the portion of the profile of the rail which is ground.

Title: Method and apparatus for the lap welding of blanks
Inventor: MININ VLADILEN FEDOROVICH
IPC: B23K20/06
Filed: 1975-09-11
Abstract: In the method, the blanks are welded by the electric current flowing between the blanks and then by the pressure, produced by a pulsed magnetic field, at the surface sections in contact with one another. The electric current used is a pulse-shaped current or a series of pulses. The apparatus has an inductor (3) and a bank (5) of capacitors which is connected to the inductor (3) via a switch element (4). A current source is connected to the blanks (1, 1' and 2) via lines. The current source can have a further capacitor, the lines being low-inductance lines in which a switch element is provided if need be. The method provides simpler and more efficient welding of tubular blanks. <IMAGE>

Title: Assembly joint for tubular elements - has snap fittings inside tubes to retain plug ends of cylindrical connectors
Inventor: DAVID-GIL JACQUES
IPC: B44C3/12
Filed: 1975-10-14
Abstract: The joint is intended for the construction of large decorative structures, which must be assembled on site and may be modified in design during their period of use. Up to six orthogonal solid cylinders (4) form a connecting element (2), each terminating at its free end in a truncated conical plug (38, 39).

Inventor: BERKMANN ADOLF
IPC: B05B15/12
Filed: 1979-03-02
Abstract: A coating booth for the electrostatic application of powdery materials onto workpieces. The coating booth has a generally tubular configuration which when viewed in side elevation is generally oval but with a spiral curved bottom front wall which melds into a flat bottom surface extending toward an outlet at the bottom of the rear wall of the booth. On the rear of the booth there is a fixed fan module to which a removable filter module may be attached so as to interconnect the booth air outlet with the suction fan module. This construction facilitates quick color changes of the powdery material by maintaining a minimum deposit of powder on the interior of the booth and by enabling the filters to be interchanged without the necessity of first cleaning the filters or of interchanging individual filter media before restarting the booth with a new color.
