Title: Rigid plastics curtain rail - comprising a hollow extruded profile partly filled with wooden stiffeners
IPC: B29C48/07
Filed: 1976-11-04
Abstract: Plastic curtain rails are mfd. which are extruded hollow profiles having cavities partly filled with wooden stiffeners. As the moulding issues from an extruder it passes through a calibrator and a cooler to give it the desired profile, and it is then conveyed by a haul-off device. The curtain rail is then conveyed by a haul-off device. The curtain rail is conveyed to a relatively large number of stiffeners which are arranged either side-by-side or one above the other and are pushed, in predetermined strokes, across the machine direction, in such a way, that each stiffener is fully pushed into the hollow of a profile. The curtain rail is then moved into the working range of a radiant heater which heats its surface so that it can be deformed in an adjacent pressure zone sufficiently for the stiffener to be firmly lodged between bottom and "ceiling" of the cvity of the profile. The movement of applying the curtain rail over the stiffener is limited by a stop on the conveyor as soon as one end of the curtain rail is flush with the trailing end of the stiffener, whilst the leading end protruding from the cavity of the curtain rail is severed. The cross-section of the stiffener is smaller than that of the cavity receiving it.

Title: Measuring speed of flow in engine air intake - using PTFE-coated wires and electronic temp. compensating unit
Inventor: KOLB FRANZ ING GRAD
IPC: G01P5/12
Filed: 1977-07-01
Abstract: In parent patent, a hot wire anemometer has two resistance wires of different dia., of the same material iwth the highest possible temp. coeffts. These are linked in a bridge with two fixed resistances and connected to the inlet of a differential amplifier, the outlet of which is connected to the bridge inlet. The two wires are in series and a tension divider is arranged in parallel with them. The output of the bridge goes to an amplifier of which the output signal regulates the feed current to the bridge. In this addn., the two resistance wires are given an increased resistance to the transference of heat between the surface of the wires and the gas flowing past. A coating is applied to the wires having poor heat conductivity and being electrically insulating. The coating consists of PTFE and it has a thickness of 10-100/mu m. A temp. monitor and an electronic unit for correcting the corresp. measured values are fitted. The device is used for the measurement of the air drawn into an I.C. engine so that the prodn. of noxious exhaust fumes can be prevented. The modification prevents the monitoring characteristics of the device drifting away from its calibration due to the depositing of dust on th wires and their erosion and deformation.

Title: Concrete slab on building roof or road - has inlaid meandering pipes conducting water absorbing solar heat
Inventor: WOERMANN HEINRICH
IPC: F24S10/70
Filed: 1978-03-31
Abstract: The building, bridge, road, or other structure, has one or more load bearing concrete slabs lying horizontally in the open air and accessible to the sun's rays - as on a concrete roof or road surface. There is a serpentine array of pipes, in the slab, parallel to its surface, to conduct a fluid conveying heat generated in it by solar radiation. The array can be connected to a reservoir with a heat pump attached. The slab's open surface may be coloured to increase absorption of heat radiation, and pipes are as light and thin-walled as possible, and pref. sited in the top half, while the slab's hidden side has a heat-insulating coating. This checks excessive slab expansion, and conserves heat to save fuel.
