Patent CA-2048674-A1 (CA)
Title: Air ejector system for fuel cell passivation
Inventor: SCHEFFLER GLENN W
IPC: H01M8/04
Filed: 1990-12-07
Abstract: A fuel cell (10) system in which a nitrogen (N2) gas is used on the anode section (11) and a nitrogen/oxygen (N2/O2) gaseous mix is used on the cathode section (12) to maintain the cathode at an acceptable voltage potential during adverse conditions occurring particularly during off-power conditions, for example, during power plant shutdown, start-up and hot holds. During power plant shutdown, the cathode section is purged with a gaseous mixture of, for example, one-half percent (0.5 %) oxygen (O2) and ninety-nine and a half percent (99.5 %) nitrogen (N2) supplied from an ejector (21) bleeding in air (24/28) into a high pressure stream (27) of nitrogen (N2) as the primary or majority gas. The ejector meters high pressure nitrogen gas with a choked orifice or venturi and uses the energy in the gas from the orifice or venturi to suck ambient air into the nitrogen stream before entering the cathode section.

Title: Bale wrapper apparatus
Inventor: FYKSE NJAAL
IPC: A01F15/07
Filed: 1990-05-25
Abstract: There is disclosed a bale wrapper apparatus (10) which can apply stretchable plastics film around a round-bale (17) and which comprises a main frame (13) which can be coupled to the front or rear of a propelling vehicle (12), a turntable (16) mounted on the main frame (13) and adapted to receive a round-bale (17) thereon with its axis (18) extending substantially horizontally, means (19, 20) for rotating the bale (17) about its axis (18), and means for rotating the turntable (16) about a vertical axis (21) so that film withdrawn from a film dispenser reel (not shown) can automatically apply air tight wrapping around the bale upon rotation of the bale about its axis (18) and rotation of the turntable about axis (21). An automatic film applicator (not shown) is mounted on the turntable and automatically cuts the film after a bale has been wrapped, and holds the cut end to apply this to a newly deposited bale on the turntable. A pick-up mechanism (23) is mounted at the front of the apparatus, with respect to its direction of forward travel, and in the operative position of the apparatus (10) it will be laterally off-set with respect to the propelling vehicle (12), so that the pick-up mechanism (23) can be aligned with a row of bales (17) lying on the ground, and the propelling vehicle can therefore move forwards in a straight line along side the row of bales in order that each bale can be received in turn by gripping arms (25) of the pick-up mechanism, and then transferred rearwardly onto the turntable (16) so that bale wrapping can take place.

Title: Method for the recovery of cyanides from solutions
Inventor: BOATENG DANIEL A D
IPC: C25B1/24
Filed: 1992-02-25
Abstract: METHOD FOR THE RECOVERY OF CYANIDE FROM SOLUTIONS          ABSTRACT            Cyanide-containing  solution  is  subjected  to  two-stage membrane electrolysis in units each comprising a cathode, an anode and one or more bipolar electrodes interspaced with cationic membranes defining alternating anode and cathode  compartments  containing  anolyte  and  catholyte, respectively.  Electrolysis causes generation of hydrogen cyanide  in the recirculating  first  stage anolyte,  and alkali metal hydroxide  is  formed  in the recirculating first-stage catholyte.   The hydrogen cyanide is stripped from the first stage anolyte and is subsequently  absorbed in catholyte in an absorption unit for the recovery of alkali  metal  cyanide-containing  solution.    Partially cyanide-depleted  first-stage  anolyte  is  mixed with  an amount of an alkali metal chloride and passed as second-stage  anolyte  through  the  second-stage  unit  for  the generation of chlorine with destruction of residual cyanide in the anolyte and the formation of alkali metal hydroxide in the recirculating second-stage catholyte from which a portion is directed to the absorption.   A substantially cyanide-free effluent is withdrawn from the circulating second-stage anolyte.  To allow for the formation of solid precipitates in the anolyte of the membrane electrolysis stages,  the  width  of  the  anode  compartments  may  be increased to at least 5 mm.  Electrolysis is carried out at current densities in the range of 20 A/m2 to 350 A/m2 and at ambient temperatures.

Abstract: ABSTRACT OF THE DISCLOSURE    An optical distance measuring  apparatus operable  in accordance with a phase difference detecting process wherein a processing system including a central processing unit and a digital type mix-down circuit detects and calculates a phase difference between the electrical phase of a signal outputted  from  a light  receiving portion in response to receipt of a reflected light beam and the electrical phase of a reference signal outputted from a reference oscillator so as to determine a distance between the apparatus and an object to be measured with reference to the electrical phase of  a  local  oscillation  signal  outputted  from  a  local oscillator is disclosed.  A circuit system of the processing system  on  the  light  receiving  side  includes  a  ladder resistance  type  attenuation  circuit,  a  multiplexer,  an alternate current amplifier, a wave shape correcting circuit and a signal amplitude detecting circuit.  When the signal amplitude detecting circuit detects that the signal derived from the reflected light beam has an amplitude in excess of a predetermined value, the central processing unit controls the  multiplexer  so  as  to  reduce  a  magnitude  of  the amplitude.   In  addition,  an  optical  distance  measuring apparatus  operable  in  accordance  with a  time difference detecting process is disclosed.
