Patent CH-678933-A5 (CH)
Title: Thermoplastic weld testing - uses test piece for microscopic examination after grinding and immersion in hot inert fluid to give relief structure
Inventor: MESSMER GUSTAV
IPC: B29C65/82
Filed: 1989-05-30
Abstract: To test the quality of a welded joint, in thermoplastic materials, a section of the welded joint is cut free with a min. thickness of 1mm. The cut surface of the test piece is ground by wet grinding. The test piece is immersed in a fluid, which is inert against the thermoplastic material, at a temp. of 120-200 deg C to heat the test piece evenly to the relatation temp. until a relief is visible. The test piece is then cooled in air. The test piece is then optically examined through a microscope to check the relief structure and the visible inconsistencies and stresses in the material which determine the quality of the weld. ADVANTAGE - The welding parameters can be checked simply and cheaply, to determine the quality of the weld which bonds the thermoplastic materials.

Patent CH-636200-A5 (CH)
Title: Method and device for removing gas bubbles and other deposits from cuvettes (cells)
Inventor: ERTL STEFAN
IPC: G01N21/15
Filed: 1979-03-20
Abstract: In this method, an ultrasonic vibrator (11) is coupled to the cuvette (10) by being pressed on and intermittently energised. Under these circumstances, the gas bubbles and deposits adhering to the walls are stripped and carried off by the sample flow. This enables the photometric analysis equipment to operate continuously. An ultrasonic pulse duration of a few milliseconds to 10 seconds with an interval length (off-time) of a few seconds to 10 minutes is preferred. The proposed ultrasonic frequency is in the range from 25 to 40 kHz and this makes possible a compact construction of the ultrasonic vibrator if materials having low sound velocity are used. <IMAGE>

Title: Mechanism for powering working stroke of hydraulic press - has flywheel mounted on motor shaft and toggle link mechanism for distributing thrust and reducing peak demand on motor throughout cycle
Inventor: RUEESCH PETER
IPC: B30B1/16
Filed: 1990-11-01
Abstract: A system for powering the press tool/blade of a press/guillotine employs a hydro-mechanical force transfer mechanism for providing the variable demand imposed by the repetitive work cycle. A motor (4) and coupled (14) pump (5) generate hydraulic pressure for operating the double-acting cylinder (2) via the conduits (16,17) and controller (6). The piston (15) travel is communicated to the links (1) which collectively form a toggle mechanism and force multiplier for the press tool (7). A flywheel (8) on the shaft (12) conveys stored rotational energy to the system to assist the drive throughout the downstroke (9). ADVANTAGE - Enables max. rating of motor to be reduced for a given press configuration and duty or alternatively working stroke can be increased for a given motor capacity. Flywheel principle can be incorporated in rotating components i.e. motor/pump rotors and coupling unit by suitable dimensioning.

Title: Selective etching of printing plates or cylinders - permits partial prepn. of cylinder to reduce prodn. time for late news items
IPC: B41N3/00
Filed: 1973-04-13
Abstract: Process for etching a printing plate or die (e.g. for rotogravure) corresp. with the images and alphanumeric charcters reqd., in which initially a part of the plate is etched to obtain a first set of images and characters, after which the entire die is Cr plated and any corrections made; the free part of the plate is then provided with a second set of images and characters by etching the Cr plating away where necessary. The Cr is pref. etched by a soln. which does not attack the Cr. Several modifications of this selective etching process are possible. The prodn. time for a printing plate is reduced to a min. In e.g. the printing of an illustrated magazine, the same cylinder for rotogravure can include advertisements and also pictures and/or texts of very recent news etc. where the time between prepn. of the plate and printing must be minimal.

Title: Process for the electrolysis of alkali metal chlorides at reduced pressure
Inventor: SPAZIANTE PLACIDO MARIA
IPC: C25B1/26
Filed: 1982-11-23
Abstract: This invention relates to a novel electrolytic method for producing chlorine, hypochlorites, chlorates and perchlorates, wherein one or more electrolytic cells are used. In this novel method, functioning of the cell is effected at least intermittently at a reduced pressure below 0.7 atmosphere absolute, thereby leading to improved circulation of the electrolyte, removal of deposits on the cathode, a controlled electrolysis temperature, greater removal of the hydrogen from the system and an extended electrode life. In the case where cells are used in which the electrodes are separated by diaphragms or membranes, the reduced pressure, preferably applied in the cathodic zone, controls the electrolysis temperature and the hydraulic flow from the anolyte to the catholyte.
