Title: Minimum adverse environmental pulp mill with feed to chlorate manufacture
Inventor: LINDBERG HANS G
IPC: C01B11/02
Filed: 1994-07-19
Abstract: Liquid effluent from a pulp mill bleach plant having at least one chlorine chemical bleach stage is evaporated and then used in chlorate manufacture.  The bleach plant effluent produced by evaporation may be stored and then transported to an off-site chlorate production location, and/or may be subjected to a sodium chloride removal process (such as evaporative crystallization) and only sodium chloride transported to the off-site location. Chlorates produced off-site can be returned to the mill (with acid any caustic that are optionally produced) for chlorine dioxide manufacture on site. The chloride-depleted stream from sodium chloride removal may be burned in the mill recovery boiler.

Inventor: BREUER GOTTFRIED
IPC: E01C11/14
Filed: 1997-03-25
Abstract: In the course of the production of a transverse force bolt  (10)  in accordance with the invention,  the sheath  (2) made of a rod-shaped pipe of stainless steel is drawn on a rod-shaped core (1) of conventional structural steel. In the process the exterior dimension can be simultaneously calibrated (20). The rod-shaped semi-finished product (3) is subsequently cut into rods (4) by means of a saw (30). By means of a hydraulic press the core is pushed out of the rod (4) by a length  (a),  and  the  ejected  portion  (5)  is  cut  off. Subsequently the core (1) is pushed back by half the length (a/2) of the cut-off portion (5), and finally the open ends (6) of the sheath (2) are closed.      This results in a transverse force bolt (10) of particularly great strength, which is very precise and extremely low cost.

Title: Hip inflatable protection device
Inventor: KEYES MARSHALL J
IPC: A41D13/00
Filed: 1995-10-25
Abstract: The invention is a self-contained protective device/system (12) designed to protect the hips, pelvis, buttocks, and coccyx areas. The device (12) may be worn outside of the clothing, and because it is small in size and lightweight, it may be easily put on and removed and does not interfere with body movements. It contains the following components: an inflatable air bag folded into pleats (22), a battery (42), a gas source (3), sensors to determine angular motion and acceleration (32), a triggering/valve mechanism to release the gas (34) and a relief valve (36). When the user falls, the sensors automatically release gas from the cartridge and inflate the air bag assembly, forcing the folded pleats to fully cover said areas. After use the relief valve is opened to release air from the air bag assembly, the pleats are reinserted into the system and the invention is ready for reuse after the spent cartridge is replaced.

Patent CA-2216201-A1 (CA)
Inventor: POHORILY PETER P
IPC: G01R31/40
Filed: 1997-11-14
Abstract: A self contained electrical status indicator that can indicate whether a load isoperating or not, it requires no batteries and uses a current transformer with alight to indicate current and another light to indicate voltage. The nature of it's design allows a user to safely connect it between an alternating current (AC) source and an electrical load utilizing plugs and sockets intended for that loadwithin seconds. It can determine whether or not a load is operating as expected and if it isn't, the device conveys the general nature about where the problem lies. The device can be left connected between the source and the load for as long as desired or it can be used temporarily. It runs on the power available from the circuit to which it is connected. One of it's two lights indicates whether or not supply voltage exists and the other indicates whether or not the load is drawingcurrent. Since the supply voltage determines the overall operation of the deviceand of the load any problems with the supply will naturally have to be overcome first. Only then can any problems in the rest of the circuit be addressed. The electrical status indicator's output can be consulted once again in this case.

Patent CA-2216889-A1 (CA)
Inventor: CYR JEAN-MARC
IPC: H02M7/04
Filed: 1997-09-26
Abstract: A soft switched PWM AC to DC power converter for a DC power supply is disclosed.  The power supply includes a power factor corrector  (PFC)  converter with a power boost topology,  a DC/DC converter with a forward topology and a fly-back converter which serves as an auxiliary power supply for the controller components.   The three converters are synchronized by a gate array logic (GAL) IC to minimize EMI noise.  The GAL also conditions the PWM for the PFC and the DC/DC converter to provide very precise switching control.          Synchronizing and PWM timing signals are derived by the GAL using a high-speed clock signal that is input to the GAL as a data input.  The clock signal is repeatedly divided using synchronous division to yield a digital monostable timing signal  that  enables  very  precise  control  of  converter switches.
