Title: Dishwasher Rack Support Assembly
Inventor: VINET PIERRE
IPC: A47B88/40
Filed: 1993-11-12
Abstract: There is disclosed a dishwashing machine of the front-loading type having a slidable support assembly enabling a dish supporting rack to be manually slid inwardly or outwardly through the access opening of the wash chamber of the machine. The assembly includes on each side of the rack an elongated channel slide member, a rack support member and two spaced apart bracket members. The elongated channel slide member supports the rack support member which is disposed to slidably move along the channel slide member so as to translate the load force of the rack to the channel slide member. Each bracket members is mounted to the wash chamber side wall and has a central body portion and upper and lower guiding flanges projecting towards the rack and converging toward each other to define a guideway surface for slidably supporting the channel slide member. Each bracket is secured to the side wall of the dishwashing machine by a post and one screw. The use of the bracket members provides a material cost savings and assembly time savings over the previous use of rollers mounted to the side walls.

Title: Method of controlling the color temperature in a sodium high-pressure discharge lamp, and apparatus to carry out the method
Inventor: BOENIGK MICHAEL
IPC: H05B41/392
Filed: 1994-01-18
Abstract: ABSTRACT OF THE DISCLOSURE           To control the color temperature of a sodium high-pressure discharge lamp, preferably having a sodium and xenon fill, which may also include mercury, without essentially affecting the color rendition index of the emitted light, or the light flux or intensity of light radiation emitted, the lamp is operated under pulsed conditions, in which the instantaneous pulse power of recurring power pulses, separated by a holding phase to prevent extinction of the lamp, is controlled.  Preferably, the overall energy of any one of said power pulses and the intervening holding pulse is maintained essentially constant, for example by varying the frequency of sub-pulses or oscillations of which the sequential power pulses are constituted.  A frequency and power controllable oscillator (1) is connected to the lamp (3) through a series LC network to effect such control, thereby permitting adjustment of color temperature and matching of the light output to selective color reflectivity of illuminated objects.
Patent CA-2118687-A1 (CA)
Inventor: ABBOTT JAMES P
IPC: G08B13/194
Filed: 1992-09-11
Abstract: In a method and apparatus for analysing an electronic image signal, the signal is treated as representing one or more cells each comprising a plurality of pixels. A set of pointers is generated and sequentially set according to characteristic values related to detailed image content. The pointers are used to address a memory array and for successive frames, the values of an address in each array row indicated by the pointer corresponding to that row is updated. In this way, for each frame the characteristic values can be accumulated so that in a single operational mode, both a time history of the image, stored in a memory, is updated and an indication is produced indicative of the occurrence or non-occurrence of an event not associated with image background. The characteristic values can be generated by randomly or pseudo-randomly selecting pairs of pixels and for each, generating a binary signal depending on whether or not the intensity of incident light on a predetermined one of the pair is greater than the intensity on the other. Over all the rows, the values in the addresses being updated can be summed, as well as the maximum value in each row. The ratio of the two sums can be time weighted averaged with respect to the ratios obtained from previous frames. The ratio is compared with the average and the result used to determine the occurrence or non-occurrence of a significant event within the image.

Title: Intermediate frequency receiver apparatus
Inventor: DORMER MICHAEL WILLIAM
IPC: H04B1/40
Filed: 1994-06-01
Abstract: A transmitting and receiving system having two or more radios, each capable of transmitting and re-ceiving a transmission signal on two or more radio frequencies where a first radio transmits on a selected frequency at a predetermined time interval and a second radio recovers the transmitted signal.   The second radio has a first intermediate frequen-cy generator which generates an intermediate fre-quency signal which is substantially equal to an integer multiple of the channel spacing whereby an image response corresponding to the selected fre-quency is separated by twice the intermediate fre-quency signal from the selected frequency. Thus, locations for the two or more transmission frequen-cies can be selected so as not to be located on the image responses corresponding to any and all of the two or more transmission frequencies.

Inventor: PANU MISAILESCU DUMITOU
IPC: F01D1/32
Filed: 1994-03-03
Abstract: The invention refers to a universal rotary power-generating machine that turns the pressure energy of fluids directly into mechanical or electric energy, depending on the demand, or changes the state parameters of the working fluid so that the operating principle, the construction form, and the efficiency may not undergo significant modifications when the working fluid (water, air, steam, gases, exhaust or exit gases, oil or combinations of such fluids) is changed. The technical problem solved by the invention is the development of a multifunctional URPM of simple and rugged construction, balanced, compact, reliable, with uniform running, having an improved efficiency as compared with existing power-generating machines, which reduces the speeding-up and braking times under 1.5 s (from 0 rpm to max rpm or from max rpm to 0 rpm) by the mere closing of the general supply valve for the working fluid, without a separate braking system being required.

Title: Composites and methods of manufacturing the same
Inventor: KO FRANK K
IPC: B29C48/07
Filed: 1993-10-27
Abstract: Composites incorporating unidirectional discontinuous reinforcing fibers are formed in one process by carding a mixture including discontinuous fibers of a thermoplastic material and discontinuous fibers of a reinforcing material to form a web, col-lecting the web into a sliver and fusing one or more slivers to form a substantially continuous thermoplastic phase surrounding the undirectional discontinuous fibers of the reinforcing material. In another process, the composites are formed by coextruding the thermoplastic material around substantially continuous fibers of the reinforcing material, severing the extrudate transversely to the fiber direction to form a multiplicity of pieces, juxtaposing the pieces so that the fibers in each piece extend substantially codirectionally with one another, fusing the pieces to form a unitary mass, and shearing the mass in a direction parallel to the fib-er direction to redistribute the fibers in the mass. The composites in accordance with these processes have physical properties which generally are greater with respect to loads in the fiber direction then with respect to loads in directions transverse to the fib-er direction.
