Filed: 1987-08-20
Granted: 1991-06-25
Abstract: Abstract of the Disclosure LOW PROFILE GEAR DRIVEN ROTARY SCRUB BRUSH    A fluid driven assembly for a rotary brush comprising a housing. The housing comprises a top side, elongated between an end, comprising a fluid receiving inlet end of the housing, and an opposite end of the housing.   The housing also has a bottom said facing substantially opposite from the top side. A cavity is provided in the housing and an opening is provided through the bottom side to the cavity.  The housing converges in cross-section between the top side and bottom side moving towards the opposite end relative to the  inlet end,  thus providing a very low profile housing but with limited internal space for mounting the fluid driven mechanism.  A fixed brush extends substantially  around  the opening.    Substantially, within the cavity, there is provided a brush mounting adaptor for removably mounting the brush facing out of the opening and adaptor gear teeth affixed to the adaptor.  Both the adaptor and gear teeth are mounted for rotation about a common first axis extending out of the opening.  Also, substantially within the cavity is a water wheel and water wheel gear teeth affixed to the water wheel.  Both the water wheel and water wheel gear teeth are mounted for rotation about a second common axis, displaced towards the inlet end from the first axis.   The water wheel gear teeth are in driving engagement with the adaptor gear teeth and the water wheel comprises water wheel vanes axially displaced towards the top side from the water wheel gear teeth and the adaptor gear teeth.  Also, within the cavity is a nozzle for dispensing against the water vanes, at a position displaced towards the inlet end from the second axis, fluid received from the inlet end.

Granted: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE         An improved apparatus and method for fabricating a composite disc brake rotor.   In accordance with this invention, a composite rotor having a stamped center section and a cast or forged braking face portion is mounted onto a press which produces a central axially deflected "bubble" of metal.   The formation of such a bubble causes radially inward straining of the material defining the rotor center section which has been found to substantially reduce surface waviness and imperfections in the surface.  Such improvements in flatness of the rotor center section provide accurate positioning of the rotor braking when mounted on the vehicle for improved brake performance and life.  Following the step of producing the center bubble, a subsequent operation is used to blank out a center mounting hole and clearance holes for wheel mounting studs.

Title: Water spray fitting
Inventor: HANSEN ALBERT F
IPC: B05B1/12
Filed: 1987-10-15
Granted: 1991-06-04
Abstract: ABSTRACT     The  invention  comprises  a  water  spray  fitting  for controlling the flow of water from a pressure water supply, typically a domestic garden hose.  The fitting comprises a body adapted to be connected to the water supply and having a hollow interior with a water inlet and a water outlet.  An internally threaded control ring is located in a transverse cut out part of the body and is rotatable therein about its longitudinal  axis to adjust the flow of water from the fitting.  A valve member extends longitudinally within the interior of the fitting and is threaded into the control ring  such  that  rotation  of  the  control  ring  causes longitudinal  movement  of  the  valve  member  within  the interior of the fitting.  The valve member has a distal end which engages the water outlet of the fitting to control the flow of water therefrom.  Movement of the valve member by way of the control ring alters the position of the distal end of the valve member relative to the water outlet.  Means sealing the valve member to the interior of the fitting on either side of the control ring and a passage for water internally through the valve member from the water inlet side to the water outlet side beyond the control ring are provided.  The valve member is formed such that the forces applied to  the valve  member  in use  of  the  fitting  by rearwardly and forwardly directed water pressure are substantially balanced.  Adjustment of  the water flow is not made difficult by back pressure acting on  the internal components  of  the  fitting.    With  the  control  ring arrangement the  fitting may  typically be  adjusted  in a one-handed operation.

Title: Fast frequency settling signal generator utilizing a frequency locked-loop
Inventor: FRIED RAYMOND L
IPC: H03L7/113
Filed: 1988-07-19
Granted: 1992-09-29
Abstract: Abstract Signal generating apparatus including a phase-locked loop (PLL) utilizing a voltage-controlled oscillator (VCO) and a frequency-locked loop (FLL) to generate an output signal whose frequency jumps from one value to another in a selectable sequence.  The signal generator further includes a delay line discriminator to provide an error signal to compensate for FM noise in the VCO.  The frequency-locked loop is implemented by utilizing the FM error signal from the delay line discriminator to stabilize the center frequency of the VCO.  The inherent wide bandwidth of the FLL provides a fast settling time when the loop is switched to a new frequency.  In a learn mode, the gain parameters of the loop are determined and stored each of a plurality of frequencies.  The gain parameters and a corresponding pretune signal for each selected frequencies are the applied to the FLL in a selectable sequence to provide a fast-switching signal generator.

Abstract: A belt with leather-simulating properties comprises outer  face sheets  of  a  flexible  leather-simulating plastic material on opposite sides of a flexible plastic sheet-like filler material to which the face sheets are attached.  In an alternative embodiment, only one outer face sheet of leather-simulating material may be used, in which case the sheet-like filler material provides a backing for the outer face sheet.   Further, the outer face sheets may be non-structural face sheets of natural leather.     The  plastic  filler  material  preferably comprises  a  synthetic  resinous  material  such  as  a polyvinyl chloride-containing  material  of  sufficient combined thickness and tensile, flexural, and hardness properties that combine with the outer face sheet(s) to provide a belt with leather-simulating properties.  The backing sheet is reinforced with a flexible nylon rein-forcing strip to prevent axial elongation of the belt. The Shore hardness of the backing sheet is near the extreme  high  range  of  hardness  levels  for  flexible thermoplastic  extrusions.     The  resulting  belt  is suitable for heavy duty uses such as for police belts or waist belts used by weight-lifters.  The invention also provides  a  dress  belt  principally  comprised  of  the plastic filler material.  The belt may have one or more outer face sheets of the leather-simulating polymeric material.   Alternatively, outer face sheets of leather may be used in combination with the filler material.

Abstract: ABSTRACT   An automatic or semi-automatic document feeder (12) for conveying documents sheets (17) into and away from an imaging position (18) on a platen (14) of a copier, incorporating a plurality of spaced-apart belts (30) moving between a white backing surface (261 and the platen. A vacuum source applies a partial vacuum to the inter-belt gaps (32) to hold a document sheet against the belts so that the document is conveyed with the movement of the belts. A major portion of the backing surface (26) lies in a datum plane. Discrete protrusions (56) which extend above the datum plane are formed integrally on the backing surface in pairs of rows, against which the belts ride to hold the belts in spaced relation to the datum plane. The spaces (57) between the protrusions provide openings so that a partial vacuum applied beneath the belts may extend into the inter-belt gaps. "Show-through" and "show-around" printing defects are thus substantially reduced because the backing surface can be entirely flat between the belts and the belts themselves require no apertures. Channels may be provided beneath the belts in the longitudinal direction thereof to ensure the application of uniform partial vacuum over the whole platen area.
