IPC: G11B27/031
Filed: 1997-02-19
Abstract: An editing apparatus is disclosed.  This editing apparatus reproduces a video signal recorded in a tape-like recording medium and repetitively records the video signal on a predetermined repetitive recording area of a disk-like recording medium until a recording starting point is designated.  Then, when the recording starting point is designated, the video signal is sequentially recorded on a predetermined normal recording area of the disk-like recording medium when the recording starting point is designated.  When a recording ending point is designated, the video signal is recorded on the normal recording area during a predetermined period, whereafter the video signal is repetitively recorded on a second predetermined repetitive recording area of the disk-like recording medium.

Inventor: BUCKWALTER DAVID
IPC: E06B7/096
Filed: 1995-08-22
Abstract: A louvre shutter mechanism is disclosed that is adpated to be assembled from kit form. The kit form is adapted so that the shutter dimensions can vary, enabling the shutter to be installed within a window frame that falls within a predetermined range of sizes. The side rails (2) of the shutter incorporate elongate channel portions (3) that are adapted to receive elongate support members (5). The support members (5) include a plurality of apertures (9) that locate pinion gears (6) projecting from the louvres (8). The support members (5) operate to support the louvres (8) as the pinion gears (6) do not engage the side rails (2). The combination of the support rails (5), louvres (8) and pinion gears (6) forms a sub-assembly that can be received with the side rails (2) and top rails (10) of the shutter. The support members (5) include a channel portion (3) that is adapted to receive a gear rack (4). The pinion gears (6) engage the gear rack (4) allowing synchronous rotation of the louvres (8). The pinion gears (6) perform the additional function of operating as spindles for the louvres (8). The use of dual functionality in the pinion gears (6) reduce the complexity of component parts in the kit and assists with ease of assembly.

Patent CA-2204972-A1 (CA)
Title: Memory management in a partially garbage-collected programming system
Inventor: THOMSON BRIAN WARD
IPC: G06F9/44
Filed: 1997-05-09
Abstract: Memory management to support calls between objects in language environments supporting automatic garbage collection and language environments requiring explicit control of object destruction is provided. Reference counting is used to automatically control the lifetime of objects requiring explicit destruction and that are to be accessible across the language boundary. A data structure is maintained in a runtime component for each object that is accessed over a language boundary. The reference count for each non-garbage collected object is incremented by the runtime in accordance with the number of cross-language references held to it. When the count reaches zero through decrements as the references are returned and destroyed, the non-garbage collected object can be safely and automatically destroyed. The runtime creates a reference to any garbage collected object accessed by a cross-language call. The reference is visible to the garbage collector, and prevents the object being collected while the reference is in existence.

Abstract: A method of balancing a hydraulic valve for a power steering gear in which the valve is subjected to a pressure medium, the valve comprising a sleeve (4) journalled on an input shaft (2), and the sleeve having a torsion bar (8) connected thereto via a driven member. The method comprises the steps of firstly inserting the valve into a balance housing (222), then secondly determining the neutral position of the inputshaft (2) relative to the sleeve, then thirdly fixing the neutral position by rotational connection of the inputshaft and torsion bar (8). The pressure medium used to determine the neutral position is gaseous medium such as air. The rotational connection of the input shaft (2) and torsion bar (8) is effected by a bonding process such as adhesive bonding (11), soldering, brazing or welding. The interface between the bore of the input shaft (2) and the fixing end of the torsion bar (8) has a support region (12) and a bonding region (13). The diametral clearance at the bonding region (13) is more than at the support region (12) so that an annular cavity (100) is provided for the bonding agent (11).

Title: Self-cleaning bar screen for storm water and the like large water volumes
Inventor: FILION GILLES
IPC: E03F5/14
Filed: 1997-05-30
Abstract: .ANG. The screen comprises a set of spaced parallel grating bars set at an inclination of about 35 degrees. The grating bars retain solids carried by the water flowing between the bars. These solids are automatically pushed down the bars and away into a collecting trough transverse to the bars by water streams flowing within longitudinal grooves formed from the top of the bars. The cross-sectional area of each groove decreases from the upper end to the lower end of the bar, so that the water accelerating down the bar grooves will constantly fill the same.

Title: Arc furnace fume collection system
Inventor: SIERADZKI CHRISTOPHER Z
IPC: F27B3/06
Filed: 1997-06-12
Abstract: The present invention provides a system and method for collecting fumes from an arc furnace of the type typically used in metal foundries. The system provides an electrode hood with extended sides for improved collection of fumes from the vicinity of the electrodes. It also provides a movable spout hood for collection of fumes when metal is tapped. A combination of a tilting manifold and stationary duct are used to maintain a path for collecting fumes throughout the entire range of motion of the furnace. The stationary duct has a group of dampers that open and close as the furnace tilts. Variable position dampers may be provided at the electrode hood and furnace door. In the bag house, there is a dust containment assembly to limit the movement of the collected dust. A variable speed fan may be used with the system. One method of the invention involves determining the pressure differential upstream and downstream of the filter bag, determining the fan speed, and closing a damper downstream of the filter to clean the filter bag when the determined values for the pressure differential and fan speed match previously set values. The entire system may be controlled by a programmable logic element to maximize efficiency. Another method involves the steps of adjusting the electrode hood damper, spout hood damper and door hood damper in response to furnace conditions.
