Patent CH-648871-A5 (CH)
Title: Method of controlling the crust in an electrolysis cell
Inventor: GRUBER ULF
IPC: C25C3/20
Filed: 1982-07-12
Abstract: In the event of a short-term change in the energy supplied by the electric mains, the thickness of the crust in a molten-salt electrolysis cell for producing aluminium is altered and has to be monitored. If the ohmic bath resistance (R) differs from a basic value (R0) by more than a value ( DELTA R) specified for each electrolysis cell, the interpolar distance is corrected by altering the cross-arm position by computer control. To do this, use is made of the product of the square of the current level (I) and the ohmic bath resistance (R) as control variable. The corrections are carried out so that the thermal equilibrium of the electrolysis cell is maintained during and after a change in the energy supplied from the electric mains. <IMAGE>

Title: Radiation scatter smoke detector - has scatter detector receivers coaxial to radiation bundle to scan different directions using photocells or sensors
IPC: G08B17/10
Filed: 1976-04-13
Abstract: Radiation scatter smoke detector scans radiation emitted from a source in the form of a bundled ray for receiving outside the source area. The scattered radiation receivers are disposed coaxially to the radiation bundle so as to scan radiation scatter from different directions. The receivers should consist of photoelectric cells, arranged so that some (14) detect the forward scatter and others (15) detect back-scattered radiation. It is otherwise possible to use sensors to detect forward and back scatter or again ray conductors which surround the ray bundles and direct these to a common receiver. Two dishes can be used to detect the radiation scatter which are combined into a cylinder, with a hollow sphere acting as radiation scatter measuring space.
Patent CH-647967-A5 (CH)
Title: Method of producing a chamber-shaped circular recess in a connecting element
Inventor: ANDREOLLA FLORIAN
IPC: B23B1/00
Filed: 1980-06-19
Abstract: A chamber-shaped circular recess is made from below in the hollow polygonal head (1) of a connecting element. This is done in a single operation by means of a single cutting tool (10). First of all the cutting tool (10) is guided perpendicularly to the longitudinal axis (X) of the connecting element into the starting cut at the thread end (3a) of the screw shank (2). The cutting tool (10) is then guided parallel to the longitudinal axis (X) of the connecting element into the base surface (1a) of the polygonal head (1). A guide surface is thus obtained which adjoins the thread end (3a) of the screw shank (2) and merges without obstacles into the wall of the circular recess (4). The mounting of the sealing ring is thereby simplified, because it can be inserted along this guide surface into the circular recess (4) without damage and without difficulty. <IMAGE>

Title: Arrangement for scavenging and charging the cylinders of a two-stroke internal combustion engine
Inventor: STEIGER ANTON
IPC: F02B3/06
Filed: 1979-05-22
Abstract: For the introduction of scavenging and charging air or of air-fuel mixture, ports (7) are provided in the cylinder cover (3) of a two-stroke internal combustion engine, being uniformly distributed over its circumference in two concentric circles (9, 10). These ports are closed on the cylinder chamber-side base of the cylinder cover (3) by valves (5) which open and close due to the pressures generated on the valve bodies. Due to the uniform distribution and an inflow of air or mixture as far as possible in the longitudinal direction of the cylinder chamber, a <<displacement piston>> advancing in this direction is formed, by means of which the combustion gases are expelled by way of piston-controlled exhaust ports, thereby achieving optimum scavenging. <IMAGE>
Patent CH-642706-A5 (CH)
Title: Process for producing a roof snow stop
Inventor: WEBER PETER
IPC: E04D13/10
Filed: 1980-06-25
Abstract: A flat portion with at least one opening (3) is punched out of the steel strip introduced into a press. In the same press and in a single operation, the portion which has been stamped out in this manner is bent to form the finished roof snow stop and is provided with reinforcing ribs. The roof snow stop comprises only two parts, that is to say the fastening part (1) with the opening (3) and a snow-retaining part (2) running approximately perpendicularly to the fastening part (1). The fastening part (1) is connected to the snow-retaining part (2) by a main reinforcing rib (4). The main reinforcing rib (4) provides the snow-retaining means with the necessary strength. The conventional operations such as bending off, making a groove and/or welding are eliminated by the above-described process steps. Consequently, the production costs are lowered and the production time is considerably reduced. <IMAGE>

Title: Means for monitoring the edge coverage of character elements in a line film, photosetting film or lenticulated film, and use of said means
Inventor: BRUNNER FELIX
IPC: G03F5/00
Filed: 1977-07-08
Abstract: The means have a film (11) as substrate on which there is located a measurement symbol (12). The monitoring measure of this measurement symbol (12) is known, and the edge of the measurement symbol (12) has an extremely steep density profile. These means are subjected to contact printing simultaneously together with a film (11) to be tested. In the contact copy thus produced, the change in the monitoring measure of a character (10) on the film (11) to be tested is compared with the change in the monitoring measure of the measurement symbol (12) of the monitoring means. The difference between the two changes in the monitoring measure serves as a characteristic value for characterising the edge coverage of the character elements (10) of the film (11) to be tested. The edge coverage can be determined quantitatively and, at the same time, rapidly as well with the aid of such means. <IMAGE>
