Title: Reactor ceiling brick suspension - by telescopic tie rods with compression spring links
Inventor: WILL RUDOLF
IPC: F27D1/02
Filed: 1979-03-24
Abstract: Three layers of graphite bricks with spacers in the reflector ceiling of a reactor are supported by horizontal inner and outer retainer bolts.

Title: Embossing calender for foam backed carpet material - with cleaning roller and suction cleaner for continuous dirt removal
IPC: D06C23/04
Filed: 1979-07-14
Abstract: Equipment for embossing the back of a foam-backed carpet material comprises a heated calender against which the material is pressed by a back cloth, and feed and offtake rollers which give the material a wrap of more than 180 deg. around the calender. The rollers are so situated that the feed roller is higher than the offtake roller, and the uncovered surface of the calender is on the lower side and above the offtake, rather than the feed, side. A brush roller is situated against the uncovered section, where it continuously removes dirt and foreign matter from the calender surface before the material is run on. The dirt falls on the outgoing material from which it is removed by a suction cleaner. The appts. ensures a continuously clean calender surface, and replaces unsatisfactory, intermittent, hand-cleaning processes.

Title: Thermostat valve for central heating radiator - overrides manual setting to return to low temp. setting at specific time daily
Inventor: BEHR WILLI
IPC: G05D23/275
Filed: 1980-03-11
Abstract: The electronic, mechanical, electromechanical, pneumatic or hydraulic valve has a setting motor controlled by a programme clock to switch the valve to a given temp. setting at a specific time. The valve can only be subsequently reset to a higher temp. setting by manual operation of the valve head. The manual adjustment of the valve is over- ridden at a particular time each day to return the valve to the lower pre-selected setting. The valve is used for a control heating system in a school, office building or factory etc. where different rooms are in use at different times, to allow them to be individually controlled while the system itself remains running. It provides a saving in energy.

Title: Tool changer with magazine plate - which is cam operated to index and slide, and has sensor overriding slide motion on empty tool position
Inventor: RUETSCHLE EUGEN
IPC: B23Q3/157
Filed: 1980-05-10
Abstract: The tool change mechanism is intended for a machine tool and has a tool magazine, comprising a plate (31) rotatable about an axis parallel to the tool spindle. The plate has tool retaining openings (33,34) in its periphery.

Title: Heat treatment of steel parts, esp races for rolling bearings - using brief immersion in liq. nitrogen to reduce residual austenite in surface
Inventor: GEIWITSCH ALOIS DIPL ING
IPC: C21D9/36
Filed: 1980-05-14
Abstract: The part is heated to form austenite, and is then quenched, followed by tempering is required to reduce brittleness. The surface region only of the part is next cooled in a liq. gas, esp. in N2, which is pref. applied as a sprayed mist. The invention is designed to eliminate residual tensile stresses in the surface zones of the parts. By selective sub-zero cooling of the surface zones, some of the residual austenite in these zones is converted to martensite, which creates an increase in vol., producing desirable compressive stresses working in opposition to the stress applied when the part is in use.
