Title: Structurally improved filter housing and mounting apparatus
Inventor: HOWETH D FRANKLIN
IPC: B01D46/52
Filed: 1987-10-01
Granted: 1993-04-20
Abstract: ABSTRACT A  self-cleaning  air  filtration  system  has  a vertically  oriented  housing   internally  divided  by  a horizontal  centerplate  into an upper  clean air discharge chamber, in which a filter backflushing system is disposed, and a lower contaminant chamber.   Interconnected partition panels are positioned within the contaminant chamber and are intersecured  between  the  centerplate  and  the  housing sidewall  section  surrounding  the  contaminant  chamber  to thereby  structurally  brace  the  centerplate  and  sidewall section, and divide the contaminant chamber into a series of vertically  extending  contaminant  subchambers  having  open lower ends communicating  with a hopper  section depending from the housing.  Lower support trusses are interconnected across lower wall portions of the subchambers and carry jack screw  filter  mounting  members  connected  at  upper  ends thereof  to  gimbal plates  which  operatively  engage  and support lower  ends of  hollow cylindrical  filter elements vertically disposed within the contaminant subchambers.  The upper ends of the filters are engaged and supported by the lower ends of clean air tubes extending vertically through the centerplate.  The jack screws are operable to place the filters in a state of axial compression so that the mounted filters form structural bracing interconnections between the centerplate and the support trusses to further increase the rigidity of the centerplate and the filter housing.   With the filters mounted in this manner their weight is borne by the  support  trusses  rather  than  the  centerplate.    The support trusses partially block the open lower ends of the contaminant subchambers to prevent the filters from falling therethrough into the hoppers during installation or removal of  the filters.   The gimbal plates provide a convenient temporary support base upon which to rest the lower filter ends  during  filter  installation  or  removal  to  thereby significantly facilitate the insertion and withdrawal of the filter elements.

Title: Method for generating a low frequency electric stimulus signal andlow frequency electric stimulus signal generating apparatus
Inventor: ANZAI HIROSHI
IPC: A61N1/32
Filed: 1987-10-01
Granted: 1992-12-01
Abstract: ABSTRACT OF THE DISCLOSURE     A method for generating a low frequency electric stimulus signal is carried out by generating the electric stimulus signal to give electric stimulus to a biological body or living body.  Either current control or voltage control,  or  both current  and voltage  controls  are performed in accordance with sound volume levels supplied from a sound source to modulate the electric stimulus signal.  A frequency of the electric stimulus signal is selected to be a low frequency.  A low frequency electric stimulus  signal generating apparatus for applying to a biological body electric stimulus comprises a control section and a current/voltage controlling section.  In the control section, a sound volume level derived from a sound source is sampled at a rate at which the biological body can feel it in substantially real time.  The respective sampled  sound  levels  are  converted  into  frequencies corresponding  to  low  frequencies  and  output,  and predetermined control information.  In the current/voltage controlling section, current and voltage stimulus signals are  frequency-modulated  separately  based  upon  the frequencies.   The control  section  and  current/voltage controlling section are included in a stimulus signal generating section.

Abstract: METHOD AND APPARATUS FOR CONTROLLING A ZONE-ADJUSTABLE           ROLL OR THE LIKE                        ABSTRACT OF THE DISCLOSURE Method and apparatus for controlling the transverse distribution of pressure applied to a web passing through a nip formed between a pressure zone-adjustable device having a first number (K) of separately adjustable pressure zones, including those for roll loading cylinders, if any, and a counter-member.  A desired linear load profile comprising a second number (N) of setting zone set values for a corresponding number (N) of setting zones is provided, the second number (N) of the setting zones being substantially greater than the first number (K) of actual pressure zones.  The second number (N) of setting zone set values are input to a zone conversion unit which is programmed with a mathematical model of the nip and are converted to a first number (K) of actual zone set values so that an actual transverse distribution of pressure applied to the web is obtained having a minimal deviation from the setting zone set value distribution.  In particular, the first number (K) of actual zone set values are input into an intelligent regulating unit provided with diagnostic and protection logic so as to constitute set values for actual zone pressures.  Each of the loading members or loading member groups of the nip to be controlled is controlled separately by means of the actual zone set values.

Title: Terminal for watthour meters
Inventor: BULLOCK DONALD F
IPC: H01R13/41
Filed: 1988-03-03
Granted: 1991-06-18
Abstract: TERMINAL FOR WATTHOUR METERS               ABSTRACT OF THE DISCLOSURE            A    terminal for a watthour meter employs an offset portion internal to the watthour meter for disposing contacting surfaces for connection to current-coil conductors at four different transverse locations.  Formation of the offset produces an under surface used as one element for capturing and applying compression force to a washer over a terminal gasket.  A projection from the opposite surface of the terminal forms a bearing surface as the other element for applying compression force to the washer over the terminal gasket.  Two holes, optionally tapped, are provided for connection of a voltaga coil lead.  One of the two holes remains free for connection even though the other may be covered by the current-coil conductor.

Title: Holding and tensioning system for a cover layer on a printing machine cylinder
Inventor: KOBLER INGO
IPC: B41F27/12
Filed: 1988-03-03
Granted: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE.       To permit uniformly tensioning a holding strip (11) in which end portions (22, 23) of a cover layer  such as a rubber blanket (24) can be inserted,  the strip (11) is coupled to a plurality of rods (9) extending radially inwardly, and uniformly distributed over the axial length of the strip (11), the rods (9) being coupled to respective pistons (5) slidable in cylinder bores (4) worked in the bottom of the groove (2). Hydraulic or pneumatic pressure can be applied to one face of the piston, the opposite face of the piston being loaded by a spring (17).   Thus, since the pressure being applied to all the pistons will be uniform, tensioning pressure (Fig. 2) will be uniform, or raising pressure (Fig. 3) will be uniform.  Rather than using fluid pressure, other non-mechanical energy, such as electrical energy, can be used to raise the strip (11) by electromagnetic coupling of solenoids to the rods (9).

Title: Process and device for producing or renewing a horizontal marking on roads and horizontal marking produced in accordance with the process
Inventor: BOLLAG MOSES
IPC: E01C7/32
Filed: 1988-04-14
Granted: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE         During the laying of a marking line with the aid of at least one paint spray gun    , profile particles     are introduced by means of a profile particle dispenser     in-to the marking composition     and thereby enveloped all round by the latter.  The dimension of the profile particles , which are preferably reflective beads, is greater than the layer thickness of the bare painted line, so that pro-file elevations are formed.  Subsequently,  reflective beads which also adhere to the profile elevations are scattered onto this profiled painted line    , which beads thus ensure a good night visibility in wet conditions and when a water film is present, from which they project.  The profile par-ticles     can either be directly introduced into the jet of paints emerging from the paint spray gun     or, subsequent to the application of a painted line, be scattered thereon and then completely covered with marking composition by means of renewed spraying of a thin film of paint.
