Patent CH-668942-A5 (CH)
Title: Typewriter ink ribbon cassette with brake on supply reel - has cantilever spring exerting pressure on core of reel for engagement of radial tooth on axis
Inventor: BUERGIN MARKUS
IPC: B41J33/52
Filed: 1986-02-06
Abstract: The core (13) of the supply reel (10) is mounted with radial play (26) on an axis (12) formed on a carrier (7) within the housing (1). The axis (12) has a single tooth (24) which engages an array of teeth (25) on the inside of the core (13) under the pressure of the cantilever spring (8). The free end of the spring (8) is angled (14) in a loop of the ribbon (4) to reduce the force on the core (13) so that the latter can be rotated further by the  amount of the width of a tooth. The fixed end of the spring (8) rests in a groove (27. ADVANTAGE - Sufficient constancy of ribbon tension in operation is guaranteed with very high security against unwinding during handling and transport, as well as under vibration in use.

Patent CH-681076-A5 (CH)
Inventor: FREI HANS
IPC: B65H29/00
Filed: 1987-03-04
Abstract: The package support device comprises a hollow cylindrical rotatable winding core member possessing a substantially cylindrical support surface for the wound-up printed products. At the winding core member there is formed a ring-shaped groove extending in the circumferential direction of the winding core member and open towards the outside. Accommodated within such ring-shaped groove is a winding band wound upon the winding core member. The ring-shaped groove can be covered by a cover member supported at the winding core member. This cover member rotates with the winding core member and is displaceable in the direction of the lengthwise axis of such winding core member in order to expose the ring-shaped groove. The cover member can also be constructed to be rotatable in relation to the winding core. A throughpass opening for the winding band is formed in the cover member.
Patent CH-692103-A5 (CH)
Inventor: LAZECKI RENE
IPC: A62B9/00
Filed: 1997-05-01
Abstract: To ensure the correct fitting of a gas mask, a measurement is taken of the air inhaled by the wearer for electronic evaluation. The measurement signal is compared with a reference value, for a correction signal to be generated. The readings show if the gas mask is being worn correctly or not. The results can be passed to a simulator. The sensor and the evaluation circuit are preferably fitted to the gas mask filter housing, with the measurements transmitted by radio, visible electromagnetic or infra red rays, optic fibers or a wire connection.
Patent CH-674319-A5 (CH)
Inventor: CADEO ANGELO
IPC: B01F15/04
Filed: 1988-03-22
Abstract: The flow rate of every amount fed out of a particular storage container (1-4) by a feed device (5-8) is measured by a flow meter (10). The flow rate is regulated by means of a regulator (9). If the actual value of the flow rates of every individual component is not equal to the setpoint value, all the flows are fed back to the respective storage container (1-4) via the reversing valve (11) and the return line (12). If all the actual values are equal to the setpoint values, the reversing valves (11) switch over so that the individual components are fed to the mixer (13) via the feedline (14). The mixture produced is again analysed in measurement units (18-20). If the actual values found by analysis are again not equal to the analytical setpoint values, the reversing valves (11) are in turn immediately switched over to the return line mode. Consequently, it is no longer necessary to remove a mixture which has not been further processed, that is to say the product, as waste during the period of time in which the control circuits are stabilising. On the contrary, the individual components are again fed back to the storage tank (1-4) so that no product loss can occur and a higher quality standard of the product can be achieved.

Title: Method for improving the efficiency of evaporators
Inventor: HAENNI HEINZ
IPC: B01D1/22
Filed: 1983-03-03
Abstract: In the separation of highly volatile fractions from multi-component mixtures in a thin-layer evaporator or falling-film evaporator heated indirectly from the outside, there are limits with respect to the maximum working temperature, particularly in the case of sensitive mixtures. By introducing an inert gas at the bottom into the mixture to be separated, the efficiency can be improved to such an extent that an enhanced separation performance can be achieved at the same working temperature.

Patent CH-653370-A5 (CH)
Title: Process for producing silver alloy materials for electrical contacts
Inventor: SHIBATA AKIRA
IPC: C22C32/00
Filed: 1982-05-24
Abstract: The fairly high temperature increase of contact materials made of silver-tin alloys subjected to internal oxidation, which is due to the high contact resistance of materials of this type, is eliminated. The high contact resistance is caused by a high concentration or supersaturation of metal oxides, including tin oxides, around the contact areas. Said high contact resistance is avoided by dissolved metals, prior to internal oxidation, being sublimed, reduced or extracted around the contact area. Said sublimation, as well as the other treatments, can be carried out after the internal oxidation of the materials.
