Abstract: IMPROVED GEAR CONFIGURATION FOR STORAGE CABINET               DRAWER INTERLOCKING ASSEMBLY                 ABSTRACT OF THE DISCLOSURE           A storage assembly (20) having a string or stack of elements (42) vertically disposed along one side of the storage assembly (20) to allow only one drawer (38) to be opened at a time.   The string of control elements (42) have lugs (64) which coact with a tab (78) on the drawer (38) to prevent the drawer from  opening.   The  control  elements  (42)  include transmission  (44,46) for rotating the control means (42)  in response to the opening of a single drawer (38).  The rotation of the single control means (42) moves the remaining control means to their respective blocking  positions.

Abstract: ABSTRACT     An  electromagnetic  feeder  driven  by  a  conventional electromagnetic  vibrating  apparatus  is  vibrated  at  the vibrational number of  50 Hz or 60 Hz  of  commercial  power source, and therefore,  in the case of a large type feeder, vibrational  noises  are  violent  and  unpleasant,  posing  an environmental  problem.    The  apparatus  of  the  present invention comprises a movable core (12) secured to one mass (7) of two masses (7) and (4) connected by a resilient member (5), two fixed cores (13) and (13') secured to the other mass (4) so that said fixed cores are positioned on opposite sides of said movable core (12), two exciting coils (15) and (15') wound about said two fixed cores, and a control circuit for alternately  applying  a  phase-controlled  current  to  said exciting coils, the mass (7) to which said movable core (12) is  secured  being  connected  to  the  object  to  be  vibrated.          Thereby,  since the vibration frequency of the movable core (12) is half of the power source frequency, unpleasant sounds caused  by  the  vibrations  can  be  greatly  reduced.    In addition, since the current can be lowered to approximately one half, energy savings are attained.

Abstract: TRUCK CAB VENTILATOR            ABSTRACT OF THE DISCLOSURE       A ventilator is disclosed for use on a pick-up truck cab  with  a  rear  slider  window.    The  ventilator  is  a rectangular  section  duct  that  extends  from  a  forwardly opening  inlet  above  the  cab  roof  to an  open  discharge confronting the rear  slider window.   As the truck travels forwards, air is taken up by the scooping action of the inlet and  is  delivered  through  the  rear  slider  window  by  the discharge opening.  The air is preferably discharged upwardly towards the roof of the cab to create a circulation of air across the roof, down the front of the cab and back through the lower portion of the cab to a discharge through the open lower  section  of the slider window.   The discharge of the duct  is  behind  the  rear  window  so  that  the  window  will function in the normal way.

Abstract: CORIOLIS-TYPE MASS FLOW METER FOR SANITARY USE            Abstract A   Coriolis-type   mass   flow   meter   for   use  in  sanitary applications.    A  pair of sensing tubes have their ends rigidly mounted  within  bores  formed  within identical inlet and outlet fixtures.   The ends of the tubes fit snugly within the bores and are  ends  brought  out  flush  with  the ends of the bores.  The flush  ends  of  the  tubes  are secured to the bores by means of welding.    An annular flange is formed about the flush tube ends of  the  inlet  and  outlet  fixtures  to allow easy assembly and removal  of  the  mass  flow meter from its associated fluid flow pipeline  or  conduit.    The inlet and outlet fixtures and tubes preferably  are  formed  from  a  non-reactive, weldable material such  as  stainless steel.  The mounting arrangement of the tubes within  the  bores of the inlet and outlet fixtures makes it easy to  secure the tube ends to the fixtures by means of welding in a readily  accessible  location.    These  welds can then be easily smoothed  or  polished  to  remove  any  possible obstructions to fluid  flow or hiding places for contamination.  This arrangement results  in  a  mass  flow meter which is acceptable for sanitary applications,  e.g.  the measuring of mass flow and or density of foodstuffs.
Patent CA-2048991-A1 (CA)
Inventor: DJORDJEVICH ALEXANDAR
IPC: G01B11/06
Filed: 1991-08-12
Abstract: This  invention  called  "Fiber  Optical  Ice  Detector"  (FOID) remotely detects early formation of ice around dedicated optical fibers on structure surfaces.  The fibers may be glued to the surface, embedded into it in case of composite materials, or otherwise attached to it.  The invention is based on the light diffusion by ice and light reflection from ice boundaries, that optically couple multimode optical fibres in specially built sensitive zones. Such zones may be multiple in order to achieve sensing distributed along the fibers (rather than at a single location). Sensitive zones consist of specially profiled cross sections that amplify the effects involved by allowing most of the light to be modulated. Thus, the invention makes it possible to achieve early detection of small quantities of ice at multiple locations along the fibers. A most widespread use of this invention is expected in the aircraft industry for remote detection of ice formation around critical parts - wings.

Title: Apparatus and method for removing common mode vibration data from digital turbine blade vibration data
Inventor: TWERDOCHLIB MICHAEL
IPC: F01D17/24
Filed: 1991-10-31
Abstract: A sensor produces a signal indicative of the actual arrival time of each turbine ba.ade at the sensor. A first circuit is responsive to the sensor for producing digital data representing the actual arrival time of each blade at the sensor. A second circuit establishes expected arrival times for each blade at the sensor. A third circuit is responsive to the digital data for generating a plurality of data entries each representing the difference between the actual arrival time and the expected arrival time. A fourth circuit stores the data entries in a first string having a plurality of dummy entries at the beginning thereof and at the end thereof and inserts into the string space saver characters an the event that the data entry for a particular blade is not produced. A fifth circuit establishes a running average value, over a plurality of data entices, for each data entry. The running average value is representative of common mode vibration. The average value is subtracted from its corresponding data entry to produce a second string wherein the entries in the second string are free of common mode vibration data.

Title: Decoding system for distinguishing different types of convolutionally encoded signals
Inventor: DENT PAUL W
IPC: H03M13/00
Filed: 1992-02-07
Abstract: A decoding system discriminates between different types of communications traffic signals. Each type of traffic signal is encoded using a different error correction code. Plural, parallel decoders each decode a received traffic signal using a different decoding technique. Each decoding technique operates in accordance with one of the error correction codes. A quantitative measurement of the reliability of a decoded result is generated by each decoder. A comparison processor accumulates the quantitative measurements made by each decoder and compares the accumulated values. That decoder having the most reliable, accumulated value is selected to decode the current traffic signals. The remaining decoders are deactivated to conserve processing time.

Abstract: Docket 910012 000 ABSTRACT OF THE DISCLOSURE An apparatus and method for injecting fluid into and producing fluid, including gas, from a subterranean formation via a well in fluid communication with the formation. Fluid is injected into the subterranean formation through a first generally tubular conduit in the well and fluid is produced from formation to the surface through this conduit until fluid flow ceases. Thereafter, fluid is pumped from the formation into the tubular conduit and diverted into the annulus defined between the conduit and the well. The pressure drop created by this diversion causes gas to break out of the produced fluid. The remaining fluid is diverted back into the conduit and pumped to the surface while the gas is produced to the surface via the annulus.
