Title: Dirt insensitive light beam based limit switch - has variable light beam intensity to give reliable performance by increasing intensity when dirt is present
Inventor: VESTER KLAUS
IPC: G01V8/12
Filed: 1974-12-27
Abstract: A light beam based limit switch for application typically to machine tools, in which a movement of some element must be limited, is relatively insensitive to dirt. The degeneration of the performance of the switches in the presence of dirt is reduced by the use of a variable intensity light source, which can be set either by hand or by an automatic control circuit so that the associated light sensitive receiver always receives an adequate signal. When an upper light intensity limit is reached, an alarm of some kind is actuated, indicating the need for cleaning of the system.

Title: Measuring device ascertaining heat transferred - part of flow to heat exchanger is tapped to additional heat exchanger to vaporise fluid in container
Inventor: NENNING PETER DR
IPC: G01K17/02
Filed: 1975-10-02
Abstract: The measuring device ascertains the quantity of heat transferred between a heat exchanger and a fluid flowing in a conduction system. Part of the flow to the heat exchanger is tapped off and fed through a further heat exchanger (3) in a sealed container (1) where it heats up and vaporises a fluid (2). Part of the flow from the heat exchanger is tapped off and fed through a second exchanger (5) in the container. The output flow is colder and so condenses some of the vaporised fluid. The quantity of fluid condensed gives a measure of the heat exchanged in the main exchanger. Operating power used is small since fluid volumetric flow measurement is not resorted to.

Title: Filament track profile for sliding clasp fastener - combining good head support with extended anchorage loops
IPC: A44B19/40
Filed: 1976-06-01
Abstract: Complementary track patterns are made from continuous thermoplastic filaments. The interlocking heads are formed by bends in the filament profile normal to the plane of the track. One supporting leg of each bead is extended to provide an elongated loop which can be secured by an array of threads for holding the track to a support tape. The other supporting leg of each bend is part of a short loop linked to the next head. Appts. is described for winding pair os tracks alternately about a common coaxial mandrel and outboard mandrels for the extended loops of each individual track. When two tracks are engaged, each of the interlocking heads is in effect supported by three short profile loops, one being its integral support and the other being the short legs supporting each of the adjacent heads. The fastening is thus inhibited from twisting and disengaging. The extended loops provide adequate anchorage area.
