Granted: 1992-03-17
Abstract: Inventor:  Greene Docket No.:  5366-FPA                   Abstract Of The Disclosure A process and apparatus is disclosed for removing a substantial portion of water and impurities from low rank coal and peat, whereby an improved coal or peat product (not found in nature) is obtained.  The low rank coal and peat are subjected to a superheated gaseous medium, thereby substantially desorbing the moisture from the coal or peat and producing superheated gases.          A substantial portion of the superheated gases produced are recycled back in contact with the coal being dried.  Sufficient heat is added to the recycled gases, in response to monitoring, so that the recycled gases are maintained in a substantially superheated condition throughout.  This process produces a dried, substantially purified product which retains a substantial portion of its volatile content, which has an improved heat value per unit weight, and which will not absorb substantial moisture when stored or transported.  In one embodiment, the process utilizes superheated steam to initiate the drying process.  In another embodiment, that minor portion of the superheated gases in excess of the original volume not being recycled are recovered, and the fuel content thereof is used to provide energy for reheating the gases being recycled.  In yet another embodiment, the processes are maintained at low pressures of under approximately 50 inches water column pressure.  The process and apparatus provided also removes a substantial portion of the impurities such as sulfur, from the low rank coals and peat.  The dried product may be cooled, and the impurities may be separated therefrom.

Title: Sunshield device

IPC: E04F10/08

Granted: 1991-11-05
Abstract: ABSTRACT OF THE DISCLOSURE     A signal generator equipped with a shading device and two light sensors is arranged on the upper side of a slat equipped with retro-reflective prisms and rotatable about a longitudinal axis.  Depending upon the sun's position relative to the slat, the light sensors are variously shaded or illuminated by means of the shading device, and when the slat is rotated about its longitudinal axis, the light sensors supply electrical code values which change in opposing directions.  A difference between the code values is fed via an amplifier to a servo-motor which rotates the slat about its longitudinal axis until the plane of incidence of the sun's rays, which passes through the longitudinal axis, is at right angles to the upper side of the slat.  This ensures that sun's rays which hit the slat are reflected regardless of the sun's position, the time of year, and the alignment of the facade plane in which the slat is arranged.

Abstract: The diorganopolysiloxane alpha, omega-diol oils are terminally alkoxylated by reacting same with a polyalkoxysilane in the presence of an organic oxime devoid of silicon atoms. The resulting functionalized oils are well adapted for the formulation of single-component, storage-stable organopolysiloxane CVE compositions.

Title: Road making apparatus
Inventor: FREEMAN PETER D
IPC: E02F3/76
Filed: 1987-05-22
Granted: 1991-04-16
Abstract: ABSTRACT         An arrangement of a roller in combination with a draft vehicle, particularly a road grader, in which the roller is secured to the draft vehicle so as to inhibit rotation of the draft frame about a vertical axis relative to the draft vehicle. There is disclosed a road grader having a roller secured to a three-point linkage so that load can be transferred to the roller. A common conduit provides means to maintain inflatable tyres providing a periphery of the roller to a common pressure.

Title: Invalid's wheelchair and like conveyances
Inventor: PAGETT JEFFERY M
IPC: A61G5/06
Filed: 1987-06-19
Granted: 1991-08-27
Abstract: ABSTRACT    To enable an invalid's wheelchair to negotiate stairways, it has a chassis frame equipped with ordinary motor-driven road wheels for level running and a pair of crawler belts for stair ascent or descent. Either the wheels or the belts may be selected, either to the exclusion of the other, as the mode of travel.  A chair or like load carrier is movably mounted on the frame, and linkage is provided so the centre of gravity of the load is adjusted to give the required stability for the selected travel mode.

Title: Substituted benzimidazole fungicide
Inventor: CHIBA MIKIO
IPC: A01N47/38
Filed: 1987-08-04
Granted: 1992-04-21
Abstract: ABSTRACT OF THE DISCLOSURE    A fungicide which is particularly effective against benomyl resistant fungi is selected from the group of fungicides represented by the formula:       wherein R is CnH2n+1 and n is 1, 2, 3 or 6 or R is phenyl.  The method comprises applying as a suspension an effective amount of the one or more fungicides selected from the formula to benomyl resistant fungi, such as benomyl resistant isolates of Botrytis cinerea.

Title: Rental and vending machine, in particular for video cassettes, and cassette boxes used for video cassettes
Inventor: MENKE WILHELM
IPC: G07F/
Filed: 1987-11-06
Granted: 1993-03-23
Abstract: ABSTRACT            The present invention relates to a rental and vending machine, in particular for video cassettes, this having a cabinet-like housing, two compartment systems that are arranged 90 as to face each other within the housing, these being used to store the cassette boxes that contain the video cassettes, with a computer controlled cassette transport system, which can be moved vertically and horizontally between the two compartment systems, and to accommodate cassette boxes and to move these from and to a specific storage compartment or the delivery/return chute within the housing, and having a reading system for reading the identification codes used to identify the cassettes, and with an operating area that is arranged externally on the housing and used to select the desired cassette and to withdraw or return a cassette, the operating field having an input keyboard and a display.  The object of the invention is characterized by a cassette transporter (46) that can be moved along a horizontal or vertical guide and can be adjusted with the horizontal or vertical guide in the vertical or horizontal direction, respectively, the drive being operable simultaneously in the horizontal and the vertical direction, and a push-pull system (153) that is arranged on the cassette transporter (46) to transport a cassette box (44) from a storage compartment or the delivery/return chute into the cassette space of the cassette transporter (46) and vice versa.

Patent CA-1287784-C (CA)
Title: Flow regulating device
Inventor: HIEMSTRA LOURENS A V
IPC: F16L55/05
Filed: 1987-11-10
Granted: 1991-08-20
Abstract: ABSTRACT OF THE DISCLOSURE       A flow regulating device comprises a chamber forming element covered by a tube of elastomeric material, which together form a flow passage leading from an inlet port to an outlet port.          The flow passage forms a first flow chamber which is partly defined by the elastomeric tube and which is configured such that flow of fluid through the chamber causes inward deflection of the tube and thus constricts the flow cross section of the first flow chamber.  The flow passage further forms a second flow chamber downstream of the first flow chamber, the second flow chamber being partly defined by the elastomeric tube, and the configuration being such that flow of fluid through the second flow chamber causes the tube to deflect inwardly and thus constrict the flow cross section of the second flow chamber.  In one embodiment the arrangement is such that vortex flow is induced in each of the flow chambers.  In a further embodiment, the flow connection between the first and second flow chambers is provided by a tortuous flow passage.
