Title: Torque balancing device for rotary snow ploughs
Inventor: MOETTELI PAUL
IPC: E01H5/04
Filed: 1991-12-05
Abstract: The rotary snow plough, which has a chassis (4) and an engine (10), has a housing (24) for the cutting drum (20). Two hold-down members designed as skids (30) are mounted on this at ground level. 
<??>At their front ends (40), which lie in front of the cutting drum in the direction of travel, the skids are of wedge-shaped design. When the skids penetrate into the snow during the clearing work, a downward force component arises at the skids due to the wedge shape. This counteracts the tendency of the rotary snow plough to climb up onto the snow. The hold-down members accordingly maintain contact with the ground and ensure that the snow is cleared uniformly and close to the ground.

Title: Control of hydrogen cooler employed in power generators
Inventor: HARGROVE HOMER G
IPC: H02K9/08
Filed: 1992-02-10
Abstract: PATENT     ABSTRACT OF THE DISCLOSURE    A system for cooling hydrogen which is used for cooling an electric power generator,  cooling of the hydrogen being effected by transfer of heat from hydrogen leaving the generator to cooling water extracted from a source which has a temperature determined by external conditions. The system is composed of an indirect heat exchanger for bringing cooling water into heat exchange communication with hydrogen leaving the generator and cooling water is supplied to the heat exchanger partially from the source and partially from cooling water leaving the  heat  exchanger.  A temperature  monitoring  unit produces an indication of the temperature of the cooling water extracted from the source and a control unit is coupled to the temperature monitoring unit to cool the hydrogen to a desired temperature while maintaining a constant  flow rate  of cooling water  into the heat exchanger.

Inventor: HARING PETRUS G M
IPC: A23L5/20
Filed: 1992-02-10
Abstract: The present invention relates to a method for improving the flavour of starch comprising incubating the starch with an enzymatically active peptidase containing cell preparation under such conditions that enzymatic peptidolysis of a substantial amount of oligopeptides in the starch is the result, which icubation is, optionally, preceded or followed by a non-enzymatic purification step such as steam stripping or solvent extraction. The starch is particularly a hydrolyzed starch. Other aspects of the invention are concerned with a starch without bitter-like off-flavour obtainable by the present method. The starch with an improved flavour is particularly suited for incorporation into food products, such as spreads.

Inventor: DALLAIRE RAYMOND
IPC: E06B7/14
Filed: 1992-02-25
Abstract: A drainage system and method of draining extruded window sill frames is disclosed.  The drainage system includes a drain cap which provides two separate drain paths for the sill.  The drain cap is installed in a drainage orifice in the bottom edge of the outer sill face.  The drain cap includes a ramp portion for directing water draining from the front of the sill through one of the drain paths, water from the rear of the sill being permitted to drain through the other drain path.

Title: Narrow band excimer laser and wavelength detecting apparatus
Inventor: WAKABAYASHI OSAMU
IPC: G03F7/20
Filed: 1990-07-12
Abstract: ABSTRACT OF THE DISCLOSURE    A narrow band excimer laser and a wavelength detecting apparatus are suitable for use as a light source of a reduction projection aligner of a semiconductor device manu-facturing apparatus.  In the excimer laser, the ruling direction and the beam expanding direction of a prism beam expander are made substantially coincide with each other, and a polarizing element causing selective oscillation of a linearly polarized light wave substantially parallel with the beam spreading direction of a prism beam expander is contained in a laser cavity.  A window at the front or rear side of a laser chamber is disposed such that the window make a Brewster's angle with respect to the axis of the laser beam in a plane containing the beam expanding direc-tion of the prism expander and the laser beam axis.  An anti-reflection film which selectively prevents reflection of a polarized light component substantially parallel to the direction of beam expanding of a prism beam expander is coated on one surface of a prism that constitutes the prism beam expander.  The wavelength detecting apparatus is con-structed to input a reference light and a light to be de-tected upon the etalon.  The light transmitting through the etalon is condensed to focus on a light detector for detect-ing the wavelength of the laser beam based on interference fringe detected by the light detector.

Title: Generating high pressure pulses in liquid
Inventor: DZIERSK WILFRIED
IPC: F04C2/00
Filed: 1992-06-11
Abstract: ABSTRACT         In order to generate pressure pulses in a liquid in a simple and cost-effective manner, the liquid is rapidly vaporized, at least in part, in a recess that is open at one end and is incorporated in a rotary piston.  To this end, the apparatus that is used to carry out the procedure incorporates two electrodes between which the recess with the liquid is situated.  Providing the current is sufficiently strong, part of the liquid will be vaporized and thus generates an over-pressure which then forces the remaining liquid through a pressure line to the outside.  It is preferred that the new apparatus be used as a high pressure cleaner.

Patent CA-2072505-A1 (CA)
Title: Code transmitting apparatus and code transmission system
Inventor: KIMURA TOMOHIRO
IPC: H03M7/40
Filed: 1992-06-26
Abstract: Although data is transmitted with efficiency by an arithmetic encoding system, the number of carry control signals increases in proportion to the number of consecutive bits "1" s or bytes X'FF's in a conventional system.  In the present invention, an arithmetic encoder 302 detects the possibility of a carry generated during arithmetic coding operation being propagated beyond at least a predetermined number of consecutive bytes X'FF's in a supplied arithmetic code 315.  When the propagation of the carry is impossible, a carry control signal is inserted into the first 2 bits of the byte other than X'FF' which occurs immediately after the consecutive bytes X'FF's so as to transmit the presence or absence of a carry.  An arithmetic encoder 303 detects the continuation of at least a predetermined number of bytes X'FF's in the arithmetic code 315, and arithmetically decodes an output value YN316 on the basis of the predicted value MPS317 of the occurrence probability of the output value YN316 to be encoded and the region width Qe of the complementary predicted value LPS.  Since the number of total bits of the inserted carry control signals is reduced by this "one-time 2-bits insertion system", the total number of transmitted code bits is also reduced.

Title: Process for decreasing n2o emmissions from a fluidized bed reactor

IPC: F23C10/02
Filed: 1993-05-04
Abstract: FROM A FLUIDIZED BED REACTOR                       ABSTRACT     Emissions of nitrous oxide (N2O) are lowered in a fluidized bed reactor utilizing two-staged combustion.  A lower region of the furnace section is operated under substoichiometric conditions so that combustion in the lower region is incomplete, thereby inhibiting formation of N2O and nitrogen oxides (NOx).  An upper region of the furnace section is operated under oxidizing conditions to promote further combustion.  An amount of particulate material is present in the upper region, and this amount of particulate material in the upper region is controlled to maintain a temperature in the upper region for destroying N2O formed during combustion.  The amount of particulate material present in the upper region may in turn be controlled by controlling the particulate material entrained from the lower region to the upper region.  The temperature is also preferably controlled within a range to permit sulfur capture by sorbent particles so that emissions of N2O, NOx, and oxides of sulfur (SOx) may be simultaneously lowered.     2d-2847I
