Title: Method of reducing data storage requirements associated with computer windowing environments
Inventor: ALECCI DONALD V
IPC: G06F9/44
Filed: 1990-11-21
Abstract: A method used in a computer system for managing attribute data for subobjects of a class of data objects. When a data object is created, a set of default attributes are stored in internal memory in association with the data object for all instances of subobjects of the data object. A set of attributes for overriding the default attributes are stored in internal memory for each instance of a subobject.    When a query or system response is required which requires knowledge of the attributes for an instance of a subobject, these final attributes are formed by fetching the default attributes associated with the data object and by overwriting the default attributes with the overriding attributes, if any, associated with the instance of the subobject. In a preferred embodiment, the invention is used in a computer windowing system in which windows are associated with data objects called widgets or gadgets and subobjects of the data objects are associated with items which are displayed within an associated window.

Abstract: PCT No. PCT/EP90/00581 Sec. 371 Date Dec. 21, 1990 Sec. 102(e) Date Dec. 21, 1990 PCT Filed Apr. 12, 1990 PCT Pub. No. WO90/12841 PCT Pub. Date Nov. 1, 1990.The present invention is related to polyurethane foam materials, pores thereof being free of halogenated hydrocarbon compounds, in particular free of CFCs, and a process for producing the same wherein no halogenated hydrocarbon, in particular no CFC is used as foaming agent. The pores of the polyurethane foam material contain minor amounts of the vaporized foaming agent used in the process of the invention, i.e. of the organic liquid product selected from the group consisting of a lower alkane having 3 to 6 carbon atoms or a mixture of such lower alkanes, said liquid foaming agent having a boiling point between -10 DEG  and =70 DEG  C. at normal pressure. In the process of the present invention said foaming agent is either finely dispersed in the mixture of the alcoholic starting component and the isocyanate starting component or said foaming agent is first emulsified in the alcoholic starting component, if necessary with the aid of an emulsifying agent, and the isocyanate component thereafter is added to this emulsion, and then the exothermic polymerization reation of the starting components is effected. Possibly, the so produced polyurethane foam material is stored for several hours or days.

Title: Fishing aid
Inventor: DAVEY BRIAN I
IPC: A01K83/06
Filed: 1990-12-18
Abstract: ABSTRACT            The fishing aid has a component which is towed through the water in use. Hooks are provided on the component for engaging a dead bait fish or a strip of bait. The hooks are so designed that the bait assumes an upright,  natural attitude during towing.  A protective  skirt  is  provided  which  embraces  the  bait  and minimises the tearing effect of the water as the device is towed.          Water impinging on the device during towing causes it to flutter from side to side with attendant lifelike motions of the skirt and bait.

Abstract: ABSTRACT OF THE INVENTION   This invention relates to a new and improved testing device which enables the operator of the device to verify the electrical output of a truck/tractor coupling attachment and which provides an indication of the status of this coupling and/or the individual circuits of the truck/tractor included in the connecting cord. This invention by its design also provides a selectively controlled output function to a trailer in a simulation mode, irrespective of the presence of a truck/tractor, to verify the status of all electrical illumination, air operated brake function, and such accessories as operated by a combination of air and electrical impulses. The source of power required for electrical purposes is supplied by a battery connected to the device. The source of air for the brake function tests is provided by an external source of compressed air rendered usable by a manual regulation in the device. This regulator permits the acurate setting and adjustment of the compressed air pressure. The truck/tractor electrical output is indicated quickly and easily from the drivers seat by selecting the circuit(s) desired and monitoring corresponding lamps on the device. Trailer electrical input is achieved easily by the operator selecting the desired circuit(s) by means of switches that supply voltage through circuit protection to the individual trailer circuits by a supplied coupling cord. Trailer air brake function, related diagnostic checks, and subsequent provision for adjustment are enabled by the manual activation of such valves and controls in this device are necessary, through standard coupling devices attached to it.

Filed: 1992-03-24
Abstract: The present invention relates to an outline enhancing device for enhancing an outline of an image formed by a video signal having rising and falling slope portions and a flat portion.  The device includes an enhancing signal producing circuit for producing an enhancing signal having first, second, and third enhancing wave forms which wave lengths are the same as those of three portions of the video signal, respectively.  A delay circuit is provided for delaying the video signal to be synchronized with the enhancing signal.  A subtracter circuit is further provided for subtracting the enhancing signal from the synchronized video signal such that three enhancing wave forms are exactly superimposed on the rising slope, the falling slope and the flat portions, respectively, without any interference to the neighbouring slopes or portion.  As a result of such subtraction, the gradients of the rising and falling slopes are made larger while the flat portion is extended.  Thus, the outline in the video signal is enhanced without producing preshoots or overshoots around the outline.

Inventor: KUMAGAI YOSHIAKI
IPC: H03J7/04
Filed: 1992-06-17
Abstract: An automatic frequency control (AFC) circuit receives input signals and generates converted signals by mixing the input signals with a local oscillation signal. An extraction circuit extracts a pilot signal, if present, from the input signals and provides the pilot signal to a switch. A frequency divider divides a frequency of the local oscillation signal output from a voltage controlled oscillator, and provides the frequency-divided local oscillation signal to the switch. The output of the switch is compared with a reference frequency in a phase comparator which generates a comparison result which controls the voltage controlled oscillator. If the pilot signal is not present, the switch selects the frequency-divided oscillation signal, to construct a phase-locked loop to stabilize the frequency of the local oscillation signal. Alternatively, an AFC circuit includes a frequency divider for selectively dividing a frequency of a pilot signal included in the converted signal.      Various frequencies of the pilot signal can be received by altering a division number in the frequency divider.
