Title: Process for vitrifying incinerator ash
Inventor: ALEXANDER MICHELLE G
IPC: C03C3/085
Filed: 1993-06-30
Abstract: ABSTRACT   The invention relates to a process of eliminating high chloride-containing incinerator ash and incinerator ash-residue mixtures, without generating excessive heavy metal-containing effluents during the actual vitrification of the ash. The process involves first pretreating the incinerator ash or ash-residue mixture, if needed, whereby the resultant ash contains less than about 3% halogen by weight and less than about 3% C.. Following the pretreatment, the ash is dried and then mixed with any additives needed to make up a vitrifiable batch mixture which will, when subsequently vitrified, form a glass possessing an excellent acid durability. A durability whereby such that the weight loss of the glass in 5% HCI solution at 95 C is 2.0 mg/cm2 or less in 24 hours. This durability results in minimal or non-detectable leaching of hazardous heavy metal or non-metallic specie and is sufficient enough durability such that the vitrified glass will easily pass the EPA's test for leachability. A suitable glass meeting the requirements is comprised of, expressed in terms of weight percent, about 47-76% SiO2, 0.8-29% Al2O3, 3.4-33.0% CaO, and optionally 0-25% R2O, wherein R2O is selected from the group consisting of Na2O, Li2O and K2O, 0-5% Fe2O3, 0-18% B2O3, 0-7% ZrO2, 0-7% TiO2, 0-10% MO, wherein MO is selected from the group consisting of MgO, BaO, ZnO or SrO, 0-8% of at least one member selected from the group consisting of PbO, CdO, Cr2O3, CuO and NiO, 0-4% SO3 with 0-4Y% Cl+F as batched.

Title: Truck Wheel-Spacing Changing Method, and Variable Wheel- Spacing Truck, and Ground Facility Therefor
Inventor: SUGIMOTO SUNAO
IPC: B61H9/00
Filed: 1993-10-13
Abstract: There is provided a truck wheel-spacing changing method in which a wheel-spacing of a truck is surely changed while the truck is self-propelled with passengers in a car or vehicle body on the truck and the running stability is not inferior to that of a conventional truck of a fixed wheel-spacing type, this method being able to be applied to both of a self-propelled truck and a tracted truck.         A variable wheel-spacing truck includes a pair of left and right bogie frames which are transversely movable relative to each other and can be fixedly connected with each other by releasable locking devices.  At least one of the wheels is slidable relative to the wheel shaft in an axial direction of the shaft.  When the truck moves from one railway of a track gauge onto a junction railway of a varying track gauge, a running paths pushes upwards auxiliary wheels of the locking means to release the locking devices.  Next, when the truck moves through the junction railway section, a pair of guide rails or a pair of rails give a push the wheels of the truck, thereby laterally shifting the left and right bogie frames each carrying the wheels relative to each other.  After a predetermined relative transverse movement of the bogie frames and wheels is completed, the running paths lower the auxiliary wheels of the locking devices, thereby activating the locking devices into a locking condition, and then, the truck is moved out of the junction railway, thereby completing a truck wheel-spacing changing operation.

Title: Locking/opening system for watertight hatch
Inventor: CARLSON EDWARD R
IPC: E05B17/00
Filed: 1993-10-22
Abstract: ABSTRACT               An improved locking feature for a water-tight hatch incorporates a positive break-open feature to facilitate opening when the hatch is jammed with ice and/or debris.    A plurality  of  radially  extending/retracting locking bars cooperate with closing cams such that, when the bars are extended,  the hatch is drawn  into tight engagement with a sealing gasket.  When the locking bars are fully retracted,  in order to release the hatch for opening, at least selected ones of the locking bars coop-erate with opening cam means whereby full retraction of the bars forcibly displaces the hatch in an opening direction with a high mechanical advantage, initially breaking the hatch free of any restricting ice formation or packed debris.   Thereafter, the hatch may be readily opened by being manually  lifted  in a conventional  manner.   The arrangement makes it entirely feasible to configure the hatch cover to be flush with its surroundings, so as to be useable in sidewalks, for example, where there may be heavy pedestrian traffic.

Title: Partition wall framing assembly for suspending gypsum board panels
Inventor: GILMORE THOMAS M
IPC: E04B2/74
Filed: 1994-03-01
Abstract: A structural frame is provided comprising opposed ceiling and floor channels and spaced apart, C-shaped metal studs extending vertically between the channels. Each stud has its single central web positioned transversely relative to the main plane of the frame. Pairs of short brackets are suspended from the webs of adjacent studs in opposed and vertically spaced relation. Each bracket comprises a horizontal V-shaped wall having downwardly extending side walls which form vertical end edges at the end of the bracket adjacent the web. A plurality of hooks extend from these end edges. A pattern of vertical slots is formed in the stud web and the bracket hooks extend into these slots and attach to the web. The bracket is sized to fit snugly between the side walls of the C-shaped stud, to reinforce these walls so that they do not collapse inwardly when loaded. A gypsum board panel having suspension assemblies attached to its back surface is suspended from the brackets as the suspension assembly clips engage the sloping segments of the bracket's V-shaped wall. The bracket end edges bear against the web and distribute the panel load thereover, so that the stud is not deformed. Each bracket is "single sided" -that is, it extends perpendicularly from only one side of the web. Thus a stud and bracket can be used to start a wall from an abutting position with another wall.

Patent CA-2124172-A1 (CA)
Title: Classification based on thermal properties
Inventor: ROOS EDWIN H
IPC: B07C5/34
Filed: 1994-05-24
Abstract: ABSTRACT     Particles are classified according to their thermal properties by means of a method in which the first step is that of deriving a first matrix composed of first emitted heat energy values for the particles (16, 18) with the particles at a uniform temperature. This is achieved using a first thermal camera (22) to derive a thermogram which is analysed by a CPU. Next, the CPU calculates emissivity equalisation factors which equalise the values in the first matrix when the values are adjusted by the factors. Then the particles are heated or cooled, typically by an infra-read beam (26). A second matrix composed of second emitted heat energy values is then derived, by the CPU, for the heated or cooled particles, using a second thermal camera 28. The CPU adjusts the values in the second matrix by the earlier derived emissivity equalisation factors, thereby producing adjusted heat energy values for the particles.          Finally, the particles are assigned classifications according to the magnitude of their adjusted heat energy values.

Patent CA-2131082-A1 (CA)
Inventor: SCHILLING DONALD L
IPC: H04B1/71
Filed: 1994-08-29
Abstract: A transmitter and receiver for spread spectrum communications using a Fourier series coefficients module, a notch gate, a fast Fourier transform module, and memory. The Fourier series coefficient module generates magnitude and phase values of a Fourier series. The notch gate notches the Fourier series coefficients at selected bands of frequencies. The selected band of frequencies are chosen so as not to provide interference with a preexisting user such as a cellular user, microwave user, or other radio communications. The fast Fourier transform generates from the notched Fourier series coefficients a spreading signal. The spreading signal has notches in its spectrum so as not to cause interference with the preexisting users. At the transmitter, the spreading signal is used to spread-spectrum process message data to generate a spread-spectrum signal for transmitting over a communications channel. At the receiver, the spreading signal is used to despread a receive spread-spectrum signal. At the receiver, the receive spread-spectrum signal has the advantage that the preexisting users are notched out and not part of the despread signal and therefore not part of the interference in the receiver detection circuits.
