Patent CA-1118652-A (CA)
Inventor: ESCHNER AXEL
IPC: F28D20/00
Filed: 1978-07-07
Granted: 1982-02-23
Abstract: ABSTRACT   A storage heating unit comprises an air-permeable heap of solid granular particles contained, as a heat-storage material, in a storage con-tainer.  A source of heat is arranged, ahead of the heat-storage material, in a flow of charging gas supplied by a charging and discharging blower.  The flows of charging and discharging gas pass in opposite directions through the entire height and length, and substantially through the entire cross section of the heat storage material, the material being of low-heat conductivity and finely-granular.  At least the flow of charging gas circulates in a closed circuit.  A second heat storage of smaller volume is arranged in the flow of charging gas after the heat-storage material but before the charging blower to protect the latter from overheating.

Abstract: ABSTRACT     The disclosed chute assembly is particularly adapted to collect the discharge from a rotary lawn or garden tractor, particularly a mower having a vertically adjustable rotary blade housing.  In the disclosed embodiment, the chute between the blade housing and the hopper has two telescopically adjustable sections, including a discharge chute which is pivotally supported on the hopper opening lip and a spiral receiving chute which is fixed to and communicates with the blade housing.  The mower blade may thus be adjusted vertically without affecting the chute assem-bly and the chute sections may be easily removed for cleaning, storage or repair.

Abstract: ABSTRACT:     An opto-electronic focussing-error detection arrangement is described for the detection of a devia-tion between a radiation reflecting surface and the plane of focuseing of an objective system.  In the path of the beam which is reflected by the surface a beam-splitting element is disposed and behind said element two radiation-sensitive detectors are arranged which are each associated with one of the subbeams formed by the beam-splitting element.  The detectors are grating-shaped detectors and are effectively divided into two detector sections by selection devices, the bounding line being adjustable. A focussing error signal is obtained which is highly independent of a positional error of the radiation-sen-sitive detection system relative to the beam axis.

Abstract: REHEAT GAS TURBINE                          ABSTRACT        The invention relates to apparatus for generating useful power and to a process for generat-ing useful power by reheating gas turbine exhaust gases to directly generate power, or alternatively, by reheating the exhaust gas to directly generate power and further reheating superheated steam by heat exchange for combined gas reheat and steam superheat-ing with optional steam reheating as well.          Steam-cooling with a steam thermal barrier for vanes and blades in a gas generator (36, 30A) or power turbine (42) offers advantages over cooling with air or water at the higher temperatures characte-ristic of the high temperature turbine technology gas turbines coupled with the reheat steam cycle. Consequently, higher cycle efficiency is obtainable for turbine (42) initial firing temperatures of about 2500°F (1371°C) and 2050°F (1121°C) reheat tempera-tures where over-all combined cycle degradation resulting from steam cooling is below about 1%.  A turbine (42) having steam-cooled components can operate at a cycle pressure ratio of about 38 without intercooling and can include steam superheating in the reheat combustor (90).

Abstract: ABSTRACT       An electrical connector for use in establishing electrical connections to the conductors of a flat cable comprises a first housing member carrying a plurality of terminals each having a conductor-receiving portion comprising a pair of spaced arms extending normally of the one face of the first housing member, the arms having opposed edges defining a conductor-receiving slot and having pointed extremities for piercing the insulating material of the cable, and a second housing member having a plurality of holes extending inwardly from one face thereof each to receive the arms of a respective one of the terminals carried by the first housing member the arms of the conductor-receiving portion of each terminal being formed adjacent their free ends with outwardly directed projections which are an interference fit in the associated hole in the second housing member, and each arm of each terminal in use engaging the second housing member not only at the projection on the arm but also at a second position adjacent the engagement between the arm and a conductor of the cable received in the slot partially defined by the arm, thereby to ensure reliable connection between the terminal and the associated conductor.       The connector of this invention has the advantage that the second position of engagement between each arm of each terminal and the second housing member serves to relieve the stresses induced in the arms by the engagement between the projections on the arms and the second housing member, this enhancing the contact between the arms and the conductors and ensuring reliable electrical connections.

Granted: 1982-11-02
Abstract: P 74 4687 TREATING PULP WITH OXYGEN ABSTRACT OF THE DISCLOSURE A wood pulp slurry is treated with oxygen in a mill with little change to the process or structure of the mill. No special pressure tanks are required. The consistency of the pulp need not be altered for the usual consistency of the pulp leaving a washer or subse-quent steam mixer without additional dewatering of addi-tional dilution. The oxygen is added into a closed section of the system so that it cannot immediately vent to the atmos-phere. Alkali should also be present when the oxygen is mixed with the slurry. The mixing should occur near to the point of oxygen addition. An existing extraction stage within the system may be used as a source of alkali. In an existing extrac-tion stage, the mixer (211) and upstream oxygen line (212) would be placed in the line between the stream mixer (206?) and the extraction tower (213?). The mixing occurs in a relatively small mixer (550) that intensively mixes the slurry and the gas. The mixer (550) has a mixing zone with a swept area of 10,000 to 1,000,000 square meters per metric ton of oven-dry pulp. A preferred range is 25,000 to 150,000 square meters per metric ton of oven-dry pulp and an optimum range of around 65,400 square meters per metric ton of oven-dry pulp. Specific mixer designs are disclosed.

No special pressure tanks are required. The consistency of the pulp need not be altered for the treatment step. It may be treated at the usual process consistency of the pulp; e.g., it may be treated at the usual consistency of the pulp leaving a washer (91'') or subsequent steam mixer (106) without additional dewater-ing or additional dilution. The oxygen is added into a closed section of the system so that it cannot immediately vent to the atmos-phere. Alkali should also be present when the oxygen is mixed with the slurry. The mixing should occur near to the point of oxygen addition. The oxygen is inserted into the pulp slurry and mixed with the pulp slurry between a washer (91'') and the subsequent storage tank (110'). The mixing occurs in a relatively small mixer (108) that intensively mixes the slurry and gas. The mixer has a mixing zone with a swept area of 10,000 to 1,000,000 square meters per metric ton of oven-dry pulp. A preferred range is 25,000 to 150,000 square meters per metric ton of oven-dry pulp and an optimum range of around 65,400 square meters per metric ton of oven-dry pulp.

Abstract: Abstract of the Disclosure A valve timing device for an internal combustion engine includes a hub with an internal helical groove which engages a tracking post extending from a cylindrical surface of a crankshaft.  A locking cap is placed at the outer end of the crankshaft spaced apart from the hub with a compression spring wrapped about the crankshaft between the hub and the locking cap.  A sprocket is keyed onto the hub and trained about a chain which is drivingly trained about a conventional camshaft.  As the crankshaft speed is increased, inertial loads of the camshaft causes the sprocket and hub to rotate relative to the crankshaft which axially moves the hub a predetermined amount along the crankshaft to compress the spring until the resilient forces of the spring counterbalances the inertia forces of the camshaft.          As the hub is angularly positioned, the camshaft becomes angularly retarded relative to the crankshaft such that the valve operation is delayed with respect to the piston operation as the engine speed increases.
