Title: Fluid flow sensor
Inventor: HAYNES JOEL E
IPC: G01F3/16
Filed: 1986-10-17
Granted: 1991-03-05
Abstract: Fluid Flow Sensor Abstract of the Invention A fluid flow sensor comprises a housing having a fluid inlet and a fluid outlet,  a measuring chamber in the housing connected at opposite ends to both the fluid inlet and the fluid outlet,  a member  in  the  chamber  movable between opposite  ends  of  the chamber,  and a valve assembly for controlling fluid flow through the  housing.   The  valve assembly is movable  between  a  first position  in  which it cuts off one end of the chamber  from  the outlet  to  that  fluid in that end of the chamber  acts  on  the movable member to urge it to the other end of the chamber,  and a second position in which it cuts off the other end of the chamber from  the outlet so that the member is urged back in the opposite direction.   The  member  oscillates  back and forth  at  a  rate proportional to the flow rate.

Granted: 1991-09-10
Abstract: Abstract of the Disclosure An  athletic  shoe   of  the  type  having  an elongated sole,  a front, a back, an  inner side and an outer side  and at least one  cleat extending outwardly from the  sole.  The cleat  includes a forwardly facing surface  and an  outwardly facing  surface  which taper towards  each other  and meet  each other  adjacent one side  of the  sole  so that  the  forwardly facing  and outwardly facing  surfaces are generally  V-shaped when viewed  in plan.   An  inwardly facing  surface extends longitudinally between the  other ends of the forwardly and  outwardly  facing sides.   In  use, the  inwardly facing surface  of the  cleat provides traction  as the athlete  steps sidewardly.    Conversely, the  tapering forward and outwardly facing surfaces minimize traction in  the event  of a  transverse  blow to  the athlete's legs.

Title: Pneumatic spring bogie, more particularly for fast-running rail vehicles
Inventor: WEIGEL RUDOLF
IPC: B61F5/20
Filed: 1987-12-23
Granted: 1992-05-05
Abstract: Man Gutehoffnungsh?tte Gmbh Nuremberg, 15 January 1987.                   ABSTRACT     The invention relates to a pneumatic spring bogie, more particularly for fast-running rail vehicles.  These vehicles need a drive device for the bogie, which transmits not only tensile and impact forces but also absorbs vibration, particularly in the longitudinal direction. To this end, according to the invention, first and second rubber buffers 10, 11 are provided and surround the bogie pin 6 in the longitudinal and transverse direction respectively, in order to drive the bogie.  The free end of pin 6 is pivotably connected by an antivibration member 14 to the cross-member 3 of the bogie frame.  Advantageously the pivot point of the bogie is placed in a region between the rubber buffers 10, 11 and the antivibration member 14.  The secondary suspension is by a pneumatic spring bellows 2 disposed concentrically with pin 6. The drive device and secondary suspension according to the invention considerably simplify the construction, in that the longitudinal member of the bogie does not need to be bent at right angles, and there is no need for connecting cods for driving the bogie or for longitudinal vibration absorbers at the sides (Fig. 1).

Abstract: ABSTRACT OF THE DISCLOSURE      A system for recognizing touch positions along a predetermined coordinate axis on a surface of a touch panel display apparatus comprises a substrate having a surface capable of propogating surface acoustic waves and is so characterized that a touch on the surface causes amplitude damping of a surface wave passing through the region of touch.  An input surface wave tranducer, coupled to the substrate surface launches a burst of surface waves on the surface in a first direction parallel to the aforesaid axis.  An output surface wave transducer is also coupled to the substrate.  A first surface wave reflecting means derives wave components from he launched wave and reflecting means that redirects the reflected components in a second direction opposite to the aforesaid first direction.      The first and second reflecting means causes wave components to traverse the display surface orthogonally to the coordinate axis along a progression of paths associated with different positions along the coordinate axis.  Circuit means coupled to the input and output transducers initiate surface wave bursts across the surface as well as detect touch-induced damping of the received waves.  The circuit means further includes means for developing an electrical signal representative of the time occurrence of the damping and thus an indication of which of the plurality of paths was traversed by the touch-damped wave and thereby the location of the touch on the display surface.      The first and second wave reflecting means are silk-screened onto the surface, and comprise a baked frit material containing a refractory nucleation-accelerating agent.

Abstract: MULTIPLE DIAL METER READING DEVELOPMENT           APPARATUS AND METHOD Abstract of the Disclosure A dial reading development apparatus includes a microprocessor for generating a multiplicity of circular numeric reading dials located in side-by-side relation of a hand-held meter recorder.  The dial simulates the dial readout of a typical gas meter. Each dial is divided into ten equal segments by lines and with a reading mark identifying a digit location to a nearest whole digit.  The proper number digit is directly related to the preceeding lesser significant number dial position.  The program sequentially presents the dial displays for different readouts.  The hand-held meter is coupled to a processor and constructed and arranged to manually insert the whole digit for each of said dials.  The processor records and compasses the inserted digits with the correct digits, and then provides various responses.  The selected digit appears above each dial with the correct digit presented next to a selected erroneous digit. The rate of presentation and the information level can be varied with the skill demand.  The identifying number digits 0-9 may be removed in a second series of dial presentations, and the dividing lines removed in a third series.  The hand-held meter reader includes keys operable to read commercially distributed meters and special indicia for inserting proper keystrokes for the trainees.  Records of the results are recorded and given by display and/or printouts.
