Title: Vacuum cap construction
Inventor: LITTELL EDMUND R
IPC: B65G47/91
Filed: 1988-11-30
Granted: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE A vacuum cup construction designed to support large items includes a planar outer plate, and a planar, generally coincidentally shaped inner plate which is smaller than the outer plate. A generally flat coincidentally shaped compressible unmolded, non-preformed sealing member, which is larger than the inner plate, is retained between the outer and inner plates by a threaded stud and a threaded nut connecting the outer and inner plates, the tightening of which compresses the sealing member. Compression of the sealing member causes the periphery to deform and form a sealing edge. A vacuum passage passes through the outer plate, the sealing member, and the inner plate to permit a vacuum to be drawn when the assembly is placed against the surface of an item or object.

Abstract: ABSTRACT OF THE DISCLOSURE       An electronic controller, for use in an automatic transmission  control  system,  for  controlling  solenoid-actuated valves to control the flow of hydraulic fluid throughout  the  transmission thereby allowing gears  and friction elements to cooperate in response to various input signals,  allowing the entire system to be adaptive to changing load demands placed on the vehicle.  Substantially all shifts are made using closed-loop control (i.e., control based on feedback).  In particular, the control is closed loop on speed,  speed ratio,  or slip speed of either Nt (turbine of the torque converter)  and Ne  (engine)  or a combination of Nt and No (output) which will provide the speed ratio or slip speed.   This transmission control is also capable of "learning" from past experience and making appropriate adjustments on that basis.

Filed: 1989-06-19
Granted: 1995-03-21
Abstract: A   spring-mass-support   structure   and   associated electrical circuitry for measuring acceleration applied to the support of the structure is disclosed.  According to one  aspect  of  the  invention,  the  spring-mass-support structure   of   the   transducer   is   fabricated   using micro-machining  techniques  of  a  silicon  wafer.   The structure  includes  E-shaped  leaf  springs  of  silicon dioxide which suspend a mass from a support structure.     The  springs as well  as  the  support  structure  and the suspended mass, are  formed by chemical etching through openings of opposite faces of a silicon wafer on which etch stop layer patterns are diffused.  Sense and force conductive patterns are diffused onto the opposite faces of the suspended mass.  The spring-mass-support structure is  then  sandwiched  between  opposite  plates  having corresponding sense and force conductive patterns which face such patterns on the suspended mass.  According to another aspect of the invention, electrical circuitry is provided by which a sense voltage and a force voltage are applied  between  opposite  sense  and  force  conductive patterns of the opposite plates creating a sense electric field and a force electric field across  the  sense and force  patterns  of  the  mass.    A  feedback  circuit arrangement is provided to substantially maintain the mass at a predetermined reference position between the support plates.   Forward circuitry of the  feedback arrangement produces a displacement signal in response to a voltage induced on the sense area of the mass as it moves  in response to acceleration applied to the support structure.          Feedback circuitry of the feedback arrangement produces an amount of charge in response to the displacement signal which is applied to the force conducting area of the mass.          The force on said mass is proportional to the product of that charge and the force electric field intensity which causes the mass to remain close to a reference position between the plates.  Alternative circuitry for providing analog   or   binary   bit   stream   representations   of acceleration is disclosed.

Title: Neck engaging support for medical device
Inventor: ROSS JUDY L
IPC: A45F3/00
Filed: 1989-12-28
Granted: 2000-03-14
Abstract: A neck engaging support for a medical device or appliance that engages and is thus supported from the neck of a medical practitioner. More specifically, the present invention is a rod-like support device having a downwardly opening, generally U-shaped hook member dimensioned to fit around the neck of a user with the open area positioned in front of the chest region with one leg of the U-shaped member having a smaller hook for engagement with an IV bag in order to support the IV bag in elevated position without using the hands such as is frequently necessary during emergency situations when a patient is being conveyed on a stretcher from the site of the emergency to an ambulance, hospital or the like. The support of this invention enables the user of the device to actually carry one end of the stretcher while at the same time supporting an IV bag in an elevated position.      The rod-like support is constructed of thermoplastic material which can be obtained in straight condition and heated to a temperature that enables it to be deformed to fit individual users with the thermoplastic rod then becoming set in the desired shape when the rod cools thereby enabling the device to be custom fitted to individual users although they can be constructed of standard sizes since the plastic rod will have some degree of flexibility to enable it to be quickly and easily positioned around the neck of the user.

Title: Wear-resistant centrifugal solids pump lining
Inventor: HEINEMAN ROLF
IPC: F04D29/42
Filed: 1990-02-19
Granted: 1993-01-19
Abstract: ABSTRACT OF THE DISCLOSURE       An  abrasion-resistant  liner for centrifugal solids type pumps comprises a  plurality  of hard metal segments attached  to  the  inner  circumferential   wall   of   a conventional  pump  in spaced apart condition thereabout.          The open spaces  thus  formed  between each adjacent hard metal liner segment  receive  a  soft  abrasion-resistant material  such  as rubber, synthetic thermoplastic resin, or  other   polymer   or   elastomer   material,  bonded, vulcanized or otherwise secured to the pump  housing  and to  the  hard liner segments, thereby forming a plurality of alternating liner segments  of hard and soft material, together  forming   an  even,   smooth   liner   surface substantially  encircling  the  impeller of the pump.  In this manner, solids  and  sharp  objects being pumped are deflected by the spaced apart  metal  segments,  reducing damage  to  the  abrasion-resistant  material,  while the metal segments also serve  to  more positively secure the soft abrasion-resistant material in bonded  condition  on the  pump  housing.    Moreover, the provision of a liner formed of a plurality of alternating segments permits the easy and quick repair of  damage  to the liner surface by simple replacement of individual hard and soft  segments, rather than the necessity of replacing an entire liner as is now common in the art.
