Title: Sheet felt
Inventor: HORNER CHARLES J JR
IPC: E04D5/02
Filed: 1996-09-05
Abstract: This invention concerns a light weight sheet felt material suitable for use as roof and siding underlayment and insulation board facing which comprises on a dry basis: (a) 60-80 wt.% cellulose fibers; (b) 15-30 wt.% glass fibers having a diameter of 5 to 16 microns and a length of 3/8-3/4 inch; (c) 4-10 wt.% binder and (d) 0.5-10 wt.% non-asphaltic, sizing agent having a flash point above 150 °F and an evaporation rate less than 1, which is selected from the group consisting of anionic rosinous and amphipathic ester and anhydride sizes and mixtures thereof.

Also the present sheet felt can be produced on conventional felt making equipment in a one step process.
Patent CA-2237098-A1 (CA)
Inventor: HOFFELNER WOLFGANG
IPC: F23G7/00
Filed: 1996-11-06
Abstract: The invention relates to a plant and process for the thermal decomposition, melting and vitrification and the recovery of substances from waste and residues of the most widely varying kinds at high temperature in a closed reaction chamber with apertures for feeding in the material to be processed and reaction substances and for removing the gaseous and fluid reaction products. Material to be processed is inserted into the reactor by feed devices (6) and thermally treated by burners (3). The melt can be agitated by special gasifying units (10). Besides being mixed by vertically blowing units, the melt can be caused to circulate by tangentially arranged units. The gas flow is regulated via valves operated by a programmable gas regulator (14). With suitable melts, the rotation can be supported by electromagnetic agitators (11) as desired. The rotation results in a uniform distribution of the material on the melt. Vertical gasification also ensures that the melts is thoroughly mixed. Both effects promote the formation of free surfaces and the intensive contact of the material with the hot, high-energy heat sources. This results in an efficient reaction. The flue gases formed are removed via the extractor for prior art subsequent treatment. Material to be processed can also be fed in beneath the melt surface. As soon as processing is completed, controlled casting is performed via the casting system with the closure device and the casting device.

Title: Sequential command repeater system for off-road vehicles
Inventor: MILENDER JEFFREY S
IPC: G05B19/042
Filed: 1998-06-11
Abstract: A control system for controlling outputs associated with off-road vehicles is disclosed herein.  The outputs are actuated by actuators in response to control signals generated by a control circuit.  In a normal mode, the control circuit generates the control signals based upon command signals generated by operator-actuatable command devices, and applies the control signals to the actuators to control the outputs.  In a record mode, the control circuit stores a sequence of commands in a memory circuit to record the sequential actuations of the command devices.  Then, in a playback mode, the control circuit generates the control signals based upon the recorded command sequence instead of the command signals. Playback can be triggered manually by a playback switch, or automatically based upon the geo-graphic position of the off-road vehicle.  The control system can record and playback more than one command sequence.  Each sequence step generates a recorded command which can depend upon a recorded event based upon values of a timer, geographic position or feedback signal.  In addition, the operator can erase, view and edit the commanded sequences.  The operator can also download and upload command sequences.

Patent CA-2245063-A1 (CA)
Inventor: JACOBS WILLIAM J B
IPC: F16L13/14
Filed: 1998-08-13
Abstract: A hanger loop of rope material provides for the suspension of innumerable articles in various industries, but is particularly well suited for use in underground mining, where it may be used to support electrical cables, pneumatic and hydraulic lines, air ventilation ducts, etc., above the floor of the mine drift. The hanger loop is preferably formed of a braided synthetic fiber which has been treated to provide flame retardant properties and which is also electrically non-conductive. Treated, braided polypropylene is a suitable material for the present rope loop. The closed loop is formed by passing the first end of the rope diametrically through its opposite end portion, and then coaxially through that same portion to secure the first end therein and to form a smaller closed loop. The second end is then inserted coaxially into the body of the main loop to secure the second end within the body of the main loop. This construction results in a braided rope loop in which the interconnected portions are pulled more tightly and securely together when tension is applied to the loop, thus producing a more secure loop which cannot slip when tension is applied. One or more article supports (S-hooks, snap hooks, etc.) may be installed on the loop at the time of manufacture, or later as desired and according to the type of support. The hanger loop may also be provided with bright, contrasting colors for better visibility in areas of low light, as in the mining environment.

Patent CA-2246819-A1 (CA)
Inventor: GRIECO LEONARDO
IPC: A21C11/00
Filed: 1998-09-08
Abstract: The present invention concerns a method and an apparatus for producing a disk of pizza dough ready for filling and baking using the centrifugal force. The system expanding the pizza dough under the influence of the centrifugal force is known for a long time. The pizzaiolo (piza baker) apply it twirling the disk of dough (overhead) in the room for expanding its diameter. Other known mechanical systems for this purpose provide very complicated devices equipped with radially oscillating levers which should guide the dough in its radial expansion. The present invention on the other hand is characterized in that the expansion of the diameter of the disk of dough under the influence of the centrifugal force is effected using an apparatus of very simple design consisting essentially of two plates (2 3) arranged coaxial one supported by the other. Themethod proposed presupposes that the dough be prepared first as a preliminary disk (1) of dough the diameter of which ranges between a third to one half of the desired final diameter of the dough disk and that this preliminary disk (1) be subject to the influence of the centrifugal force in a room determined onboth sides by two rolaling plane surfaces. The great simplicity of the apparatus realising the present invention permits its large scale application in every small pizzeria.

Title: Preparation of lactams from aliphatic .alpha.,.omega.-dinitriles
Inventor: HERKES FRANK EDWARD
IPC: C07D211/76
Filed: 1997-05-07
Abstract: A process for the preparation of five-membered or six-membered ring lactams from aliphatic .alpha.,.omega.-dinitriles has been developed. In the process an aliphatic .alpha.,.omega.-dinitrile is first converted to an ammonium salt of an .omega.-nitrilecarboxylic acid in aqueous solution using a catalyst having an aliphatic nitrilase (EC 3.5.5.7) activity, or a combination of nitrile hydratase (EC 4.2.1.84) and amidase (EC 3.5.1.4) activities. The ammonium salt of the .omega.-nitrilecarboxylic acid is then converted directly to the corresponding lactam by hydrogenation in aqueous solution, without isolation of the intermediate .omega.-nitrilecarboxylic acid or .omega.-aminocarboxylic acid. When the aliphatic .alpha.,.omega.-dinitrile is also unsymmetrically substituted at the .alpha.-carbon atom, the nitrilase produces the .omega.-nitrilecarboxylic acid ammonium salt resulting from hydrolysis of the .omega.-nitrile group with greater than 98 % regioselectivity, thereby producing only one of the two possible lactam products during the subsequent hydrogenation. A heat-treatment process to select for desirable regioselective nitrilase or nitrile hydratase activities while destroying undesirable activities is also provided.
