IPC: C21C7/06
Filed: 1964-03-04
Abstract: 1,065,612. Contacting gases with liquids &c. IMPERIAL CHEMICAL INDUSTRIES Ltd. Feb. 21, 1964 [March 4. 1963], No. 8611/63. Heading B1R. [Also in Divisions B5 and F4] A packing for film flow liquid cooling apparatus comprises a stack of alternate flat and corrugated sheets, each corrugation having a portion which is curved in the plane of the sheet to an extent sufficient to preclude a straight line path through that portion of the corrugation. As shown, each corrugation has two sides 1, 2, which form a V at an apex 3 with an included angle of 60‹, and has an upper curved portion 10, 11 and a lower straight portion. In the curved portion the corrugation is first displaced by a distance C to one side of the axis 5, i.e. the vertical line passing through the uppermost end of the apex 3, and is then displaced by a distance D to the other side of the axis, the distances C and D each being equal to half the width of the corrugation B. The lower part of the corrugation may be curved to such an extent that the lowermost point of the apex 3 lies on the axis 5 (Figs. 3 and 5, not shown), while in the embodiment of Fig. 1 (not shown) the upper portion of the corrugation is displaced to only one side of the axis by an amount equal to the width of the corrugation. When the sheets are assembled alternately with flat sheets to form the packing, the corrugations may all curve in the same sense (Fig. 4, not shown) or may be arranged (Fig. 5, not shown) so that the corrugations (30) and (34) of the sheets on opposite sides of the flat sheet (32) curve in opposite senses. The three sheets are secured together by stud and socket means at those points (35, 36) at which the corrugations on opposite sides of sheet (32) could be in contact if the latter were omitted. The sheets are formed of organic thermoplastic material; a list of suitable materials being given.

Title: Solar collector with heat pipe transfer circuits - to fluid reservoir and convective loss reducing face grid
IPC: F24S10/30
Filed: 1982-07-06
Abstract: Collector consists of a sloping space exposed to radiation. Heat is transferred from the space by a circuit containing heat pipes which are filled with a liquid and its vapour. Heat from the collector is conducted by the heat pipes to a storage vessel coupled with their walls. Several independent transfer circuits feeding several sepd. thermally coupled compartments may be used. The heat pipes may be partly formed into loops and the flow in the downward leg is turbulent during circulation. Reverse circulation during insolation-less periods is suppressed. The surface of the collector is divided into polygonal cells by insulated ribs where the height of each rib is at least 1/10 square root of the cell area. Heat transfer from a solar collector to a heat storage vessel. System contains no moving parts or control systems and is self regulating therefore eliminating maintenance. Ribbed cells on the collector surface reduce convective heat losses.

Title: Weighing device with balances on endless track - allows balances to damp out to reach and detect end position for deriving digitally weight of objects
IPC: B07C5/18
Filed: 1983-10-06
Abstract: The weighing device has several moving balances, each of which is adapted to take a position that is dependent on its weight load. It has a region in which objects to be weighed are fed to the balances and a second region in which the balances come to rest at their final positions. A detector indicates the final position of the balances in digital form. A calculator derives from the digital indication of the balance position the weight load of the balance in digital form. Electromagnets at the entrance side of guides, cooperate with a magnetically sensitive part of the balances. A movable part of the balances has an optical contrast, and the detector has a light sensor. The detector is a camera with a large number of light sensitive areas. The detector has a magnetic distance measurer of the magneto strictive type, and a mechanical pulse is generated at a location dependent on the location of the magnetic part of the balances. A signal is dependent on the time the mechanical pulse needs to travel from the generated location to the receiver.
