Patent DE-3169797-D1 (DE)
Title: System and method for heating a liquid by solar heat
Inventor: BREKKE CARROLL ELLERD
IPC: F24J2/44
Filed: 1981-05-19
Granted: 1985-05-15
Abstract: A solar heating system has a solar heat collector (14) in which water (12) is heated and which is connected by conduits (20, 22) to a heat exchanger (16) for heating a domestic hot water system or to a swimming pool. The collector is located at a higher level, such as the roof of a house. Circulation of liquid is ensured by means of a vapor (24) generated inside the collector (14), with a lift tube (30); the vapor is cooled in a condenser (41) above the collector, by heat-exchange with the water also lifted in the lift tube, and which then returns by a conduit (46) to the collector. The system is arranged so that the interior of the collector is under reduced pressure so that the water boils at below normal boiling point, by a column of water of height 7.25 metres in a vertical conduit (34) the top (28) of which communicates with the inside of the collector and the bottom of which (60) may be open to the air (62) or closed, whereby the column of water and conduits (20, 22) can be shorter. Two lift tubes may be provided for greater pumping efficiency. An extra cooling chamber can be provided, communicating with the condenser (41).

Title: Television ghost cancellation system with ghost carrier phase compensation
Inventor: HOLMES DAVID DUNLAP
IPC: H04N5/21
Filed: 1982-06-15
Granted: 1985-06-05
Abstract: A television ghost signal cancellation system is provided in which the video intermediate frequency signal is demodulated by two synchronous detectors. A picture carrier extractor produces a first reference signal for the first of the synchronous detectors exhibiting a phase which is aligned with that of the picture carrier of the direct television signal. The first reference signal is shifted in phase by a controllable phase shifter to develop a second reference signal for the second synchronous detector. The output of the second synchronous detector is delayed by an amount of time equal to the difference in time between the appearance of the direct signal and a detected ghost signal. The amplitude and polarity of the delayed signal are adjusted by a control circuit to produce a pseudo-ghost signal. An amplitude comparator compares the amplitude of the pseudo-ghost signal with that of the output signal of the first synchronous detector. The resultant amplitude comparison signal is sampled and stored during a sampling interval, and the stored signal is used to control the adjustment provided by the amplitude and polarity control circuit. A phase comparator is responsive to the outputs of the amplitude and polarity control circuit and the first synchronous detector for producing a phase comparison signal. The phase comparison signal is sampled and stored during a sampling interval, and the stored phase comparison signal is used to control the phase shift provided by the controllable phase shifter. The pseudo-ghost signal and the output of the first synchronous detector are summed to produce a deghosted video signal.

Title: Method for the production of railway rails by accelerated cooling in line with the production rolling mill
Inventor: ACKERT ROBERT JAMES
IPC: C21D9/04
Filed: 1983-06-27
Granted: 1989-05-24
Abstract: Railroad rails having improved wear resistance, are produced by controlled forced cooling from above the austenite transformation temperature, to produce rails having a fine pearlite metallurgical structure in the head portions (6) of the rails. Apparatus comprising a series of cooling headers (la, 1b) utilizing a liquid cooling medium, such as unheated (i.e. cold, or ambient temperature) water, alternating with a series of air zones (2a, 2b), is preferably arranged in line with the production rolling mill, to receive hot rails as they emerge from the mill, without the necessity of intervening reheating. A roller type restraint system (9) transports the rails through the cooling apparatus, while restraining them in the appropriate position. Each segment of the rail length is intermittently subjected to forced cooling by spray application of the liquid cooling medium, applied to the head portion (6) and the central portion of the base bottom (7) of the rail, with means being provided to prevent spray from impinging on the web and base tips of the rail: During the intervals between applications of forced cooling, heat soaks back from the web portion (4) of the rail, the operating parameters of the system being so arranged that the temperature of the rail remains essentially above the martensite formation temperature. A computerized control system discontinues the application of forced cooling, at a predetermined stop temperature, also above the martensite formation temperature. The apparatus and method are capable of producing rails having the desired fine pearlite structure in the head portion, on a consistent basis, notwithstanding wide variations in temperature between different rails, and different segments of the same rail, as they emerge from a conventional production rolling mill.

Title: Anchoring device for the traction member of an anchor, especially a rock anchor
IPC: F16B13/00
Filed: 1985-12-24
Granted: 1988-06-01
Abstract: An anchoring apparatus for insertion into a borehole in a rock stratum for supporting the rock surface or wall, such as in a rock tunnel or rock excavation, includes a tension member in the form of an axially elongated steel rod with force transmission ribs on its outer surface and an anchoring element, such an anchoring nut, engageable with the rod. The anchoring element has an inside surface with inwardly extending projections and the adjacent flanks on the projections form grooves within which the force transmission ribs engage. The anchoring element is formed of a higher strength material than the rod. When a predetermined axially extending tension force acting on the rod is exceeded, relative movement takes place between the anchoring element and the rod. The flanks on the projections on the anchoring element in contact with the ribs on the rod shear off a portion of the ribs contacted. Accordingly, while the predetermined force is exceeded, the shearing action proceeds and affords a sliding anchoring effect between the rod and the anchoring element.
