Title: Liquid removal apparatus and method for wood pulp
Inventor: SALMINEN REIJO K
IPC: B30B9/10
Filed: 1992-08-13
Abstract: A pulp dewatering and washing apparatus comprising a pressure vessel in which is contained a table assembly having a foraminous surface, in the form of a conveying belt, on which a pulp slurry is deposited.      A differential pressure chamber in the table assembly is vented to a lower pressure location to cause a pressure differential across the pulp slurry to cause dewatering.   Also, wash water is deposited on the dewatered pulp in sequential cycles to accomplish washing. A contact plate is provided to press the pulp slurry to aid in dewatering. The conveying belt of the table assembly on which the pulp slurry is deposited is stationary during the dewatering and washing, and then after the pressure differential between the vessel and the pressure differential chamber is reduced to zero, the conveyor belt moves the dewatered and washed slurry to a discharge location.

Title: Michelson interferometer
Inventor: TANK VOLKER
IPC: G01J3/453
Filed: 1992-08-26
Abstract: In each arm of a Michelson interferometer (IF) a retroreflector (110; 110') having its aperture plane aligned perpendicularly to the optical axis is mounted on a respective holder (106; 106') which in turn is rigidly connected to one end of a shaft (105; 105') rotatably mounted in a connecting member (103; 103').  To the other end of the shaft (105; 105') a first gear (107 1; 107 1') is secured which is coupled via a toothed belt (109; 109') to an identically configured second gear (107 2; 107 2') which concentrically to a drive shaft (102; 102') of an electric motor (101; 101') is rigidly connected to the housing (1010; 1010') thereof.  At a predetermined distance from the shaft (105; 105') the drive shaft (102; 102') is fixedly connected to the connecting member (103; 103') so that on rotation of the motor drive shafts (102; 102') the length of the optical paths is shortened in one interferometer arm and lengthened synchronously therewith in the other interferometer arm, or vice versa. Furthermore, the aperture planes of the two retroreflectors (110, 110') always remain unchanged aligned perpendicularly to the optical axis (Fig. 2).

Title: Method and apparatus for the reduction of distance-dependent voltage increase of parallel high-frequency electrodes
Inventor: KOTIKANGAS KAUKO
IPC: F26B3/347
Filed: 1992-04-13
Abstract: The invention concerns a method and equipment for the compensation of voltage increase in electrodes of an apparatus used to process dielectric materials. In the apparatus the electrodes are arranged parallel, at a constant distance from each other across the conveying path of the material to be treated. Electric power to the electrodes is supplied by connecting the adjacent electrodes to an opposite pole of a high frequency power source. In order to minimize the voltage increase in the electrodes, a reverse magnetic field is brought to influence with the magnetic field of each electrode, by arranging a return path for the electrode current at a suitable distance from the electrode and connecting these return paths to the return paths of the adjacent electrodes.

Title: Two-frequency transmitting apparatus with tone-modulation phasing for an instrument landing system
Inventor: GREVING GERHARD
IPC: G01S1/14
Filed: 1993-02-15
Abstract: Two-frequency transmitting apparatus (S1, S2, LA) for instrument-landing systems is disclosed which is in-sensitive to so-called DDM distortions caused by re-flections of the clearance signal from obstacles (H) located near the runway (RW). This insensitivity is achieved by different phase shifts of the equal modu-lation frequency (90 Hz and 150 Hz) used for the course and clearance signals. The different phase shifts cor-respond to a phase shift of a common fundamental fre-quency (30 Hz). The two-frequency transmitting apparatus can be used to specify a localizer course or a glide path.

Patent CA-2096332-A1 (CA)
Inventor: BRABETZ LUDWIG
IPC: G01N27/22
Filed: 1991-11-11
Abstract: Abstract A measuring instrument has a measuring arrange-ment and a measuring circuit (1).  The measuring cir-cuit (1) determines the capacitance of a capacitor (Cp) and the conductance (Rp) of the measuring arrangement, which is formed from a casing and a sensor element around which a mixture flows. The alcohol content of the mixture is determined therefrom. The measuring circuit (1) has an oscillator (20)  and a control  circuit (30)  connected upstream thereof. The measuring arrangement, which is represented  by  the  capacitor (Cp)  and  the  conduct-ance (Rp), is a part of the oscillator (20), which oscil-lates within a measuring cycle at three different oscil-lator frequencies  which  are  set by three  different control voltages of the control circuit (30), and evalu-ated in a microcontroller. Component tolerances which influence the oscillator frequencies can thus be taken into account.            Figure 2

Patent CA-2105319-A1 (CA)
Inventor: HENSEL KARL
IPC: B60C23/08
Filed: 1993-09-01
Abstract: It  is common on highways for trailers or self-propelled vehicles to utilize and rely on wheels which are filled with pressurized air.   Such pressurized wheels are subject to loss of air pressure for a variety of reasons. This invention relates to a detection device which is secured unto an axle and near a wheel, located either on a trailer, or a self-propelled vehicle, and by its workings, able to detect when a sufficient loss of air pressure has occurred in the tire of the approximated wheel, and thereafter continuously able to alert the operator of potential danger due to the loss of air pressure.  Similar detection devices would be attached near each wheel and would provide maximum detection for a vehicle or trailer.  The audio and/or visual warning triggered by the detection device would indicate for the operator to quickly slow down and safely stop to give visual inspection to the pressurized tire and determine the next step of action, thereby avoiding a potential danger to lives and/or property, which can occur when an undetected loss of air pressure leads to  a  tire  separation  or  other  tire  malfunctions  while travelling on a road way.

Title: Mixed surfactant system as a durable fabric coating
Inventor: NOHR RONALD S
IPC: D06M101/18
Filed: 1994-04-11
Abstract: A composition for increasing the resistance to removal by an aqueous liquid of surfactants from a polymeric fabric including fibers having a plurality of fiber-fiber interstices at junctions of two or more fibers. The composition includes water, a first surfactant, and a second surfactant which is structurally dissimilar to and less soluble in water than the first surfactant. One of the first and second surfactants has a solubility in water at 20°C no greater than about 5 percent by weight, based on the weight of the water. In certain embodiments, the first and second surfactants are adapted to preferentially locate in the fiber--fiber interstices and resist removal therefrom by aqueous liquid. The preferential location of the surfactants in the fiber-fiber interstices of the fabric is accomplished by working the fabric after application of the composition to the fabric. The resulting fabric is wettable and demonstrates increased resistance to removal of surfactants by an aqueous liquid, compared to similar fabrics which have not been worked. The wettable fabrics are especially suited for incorporation in such disposable absorbent articles as diapers, feminine care products, such as sanitary napkins and tampons, incontinent care products, training pants, wipes, and the like.
