Abstract: The three-dimensional prism puzzle includes an internal mechanism including a cylindrical body divided along a vertical axial plane into two identical portions mutually adjustable by rotation about a radially extending connecting pivot fitted centers.  The prism has external exterior segments nominally grouped into three horizontally layered assemblies or structures, namely a middle structure and two adjacent peripheral structures. The cylindrical body portions have at their ends radial projections for mounting exterior segments belonging to the peripheral structures, which segments are provided with complementary recesses, and the shape of these exterior segments is defined by four vertical planes traversing the geometrical center of the prism at an angle of 75° with respect to intersecting vertical faces of the prism.  The exterior segments of the middle structure are fastened on respective portions of the cylindrical body of the internal mechanism the dividing plane of which includes with a longer opposite face of the exterior segment of the middle structure an angle of 15°.  The ratio of the length of the base of the prism to its height equals cos 15°.

Title: Compact device for checking a header error in asynchronous transfer mode cells
Inventor: YAMASHITA HIROSHI
IPC: H04L12/70
Filed: 1992-01-15
Granted: 1996-10-22
Abstract: In a device for checking a header error in a header part of an STM (synchronous transfer mode) signal (S) which part comprises first through P-th header blocks and an HEC          (header error check) block, each header block comprising first through N-th ATM (asynchronous transfer mode) cell header units, the HEC block comprising first through N-th ATM cell HEC units, a sole error checking section (33, 35, 37) checks the header error in connection with an n-th ATM cell header unit of a p-th header block and an n-th ATM cell HEC unit when a collective control signal indicates the n-th ATM cell header unit of the p-th header block and the n-th ATM cell HEC unit, where n is variable between 1 and N, both inclusive, p being variable between 1 and P, both inclusive. A signal producing section (15) produces the collective control signal for indicating successively the first through the N-th ATM cell header units of the first through the P-th header blocks and subsequently successively the first through the N-th ATM cell HEC units.  On monitoring an ATM cell of a preselected  number of bytes, the ATM cell may be converted into a converted cell of the preselected number of bytes plus an empty byte at first.  Subsequently, an error correcting code is calculated from the preselected number of bytes of the converted cell and is placed in the empty byte to form a full cell.

Title: Capacitance pressure transducer
Inventor: PANDORF ROBERT C
IPC: G01L9/12
Filed: 1992-12-14
Granted: 1996-08-13
Abstract: The  present  invention  provides  a  capacitance  pressure transducer of increased thermal and mechanical  stability and thus performance over prior art designs.  A cell formed by a cell housing containing a plane parallel capacitor plate and an inlet tube is connected to an outer protective cover solely by the inlet tube.  The cell housing is contained within an air tight  environmental  enclosure  (also  supported  solely by the inlet  tube)  of  sufficient rigidity  as  to  isolate  the  cell housing  from  changes  in  atmospheric  pressure.   The  plane parallel capacitor plate  is  formed  by  a  circular  diaphragm peripherally connected to the tension ring  and an electrode disk located within the tension ring.  The capacitor plate is mechanically isolated by a connection between the tension ring and the cell housing that is more flexible than the tension ring itself and a mounting for the electrode disk by which the electrode disk is connected solely to the tension ring by an annular support member holding the electrode disk in a fixed position  relative  to  the  diaphragm.   Additionally  a  baffle plate  divides  the  cell  housing  into  baffle  and  diaphragm chambers to allow the gas to reach thermal equilibrium with the cell  before  exposure  thereof  to  the  diaphragm.   Also,  the baffle chamber and inlet tube have characteristic dimensions greater than the mean free path of gas molecules at the lowest pressure  to  be  measured  to  suppress  thermal  transpiration effects.

Title: Sealed air dryer with turbosaver valve
Inventor: SLOKA ALAN
IPC: B60T17/00
Filed: 1993-03-01
Granted: 1999-01-26
Abstract: An air dryer having a turbosaver valve which prevents the supercharged air from the engine from being discharged through the air dryer.  The air dryer comprises a stepped control port bore adapted to slidably receive the turbosaver valve for selectively sealing the control port bore and the air intake bore. The turbosaver valve is intermediate the drying chamber and the purge valve so that the turbosaver valve controls not only the flow of air through the coalescing filter but also the discharge of the purge air and the contaminants.  Disposing the turbosaver valve intermediate the drying chamber and the purge valve insures that the compressed air must pass through the coalescing filter in the loading mode while permitting the purge air to by-pass the coalescing filter in the unloading mode.  In the loading mode, the compressed intake air forces the turbosaver valve to directly seal the control port bore in order to prevent the compressed air from the intake port from passing downstream of the coalescing filter and contaminating the desiccant filter.  In the unloading mode, the turbosaver valve directly seals the air intake port in response to a control signal, allowing the purge valve to be opened without purging the supercharged air from the engine to the atmosphere during the unloading cycle.  The turbosaver valve permits the purged air to bypass the coalescing filter which minimizes the back pressure in the desiccant filter to decrease the purge time of the dryer and to increase the efficiency of the air dryer.

The locking system is used for securing and releasing a sliding undercarriage from a pair of parallel rails mounted on an underside of the semitrailer, the parallel rails having spaced apart locking pin holes along their length. The locking system includes one pair or two pair of air cylinders with pistons. The air cylinders are mounted on the sliding undercarriage and disposed next to the parallel rails. Locking pins are attached to each piston with a portion of the locking pins inserted into selected locking pins holes in the parallel rails when in a locked position. A 4-way air valve is connected to the air cylinders and a pressurized air source on the semitrailer. The air valve directs pressurized air to the air cylinders for retracting and extending the pistons in the cylinder. An air pressure switch is connected to a pressurized air line to the semitrailer air brakes. The air pressure switch is connect to and controls the operation of the air valve when retracting and unlocking the locking pins from the locking pin holes. The air pressure switch allows pin retraction only when air pressure is released to the semitrailer air brakes and spring brakes on the semitrailer are set. A pin release lever or pinrelease button is attached to the air valve and is used for releasing the locking pins when the spring brakes have been set.

Abstract: The training, load supporting component of a product conveyor is connected to a powered, leading component by a shock absorbing tow bar that employs a dampener tube in which a plunger moves against the resistance of a sleeve of resilient material.      The head of the plunger is oversized with respect to a passageway defined by the sleeve and thus is forced to compress and displace the resilient material in order to move relative to the passageway in response to an impact caused by rapid acceleration or deceleration of the conveyor. Compression and displacement of the material occurs at a zone of contact of the head with the material, the head shifting the zone of contact and compressing and displacing the material in response to the impact communicated to the tow bar. A protective sleeve shields an exposed plunger rod from contaminants and enhances the structural integrity of the assembly.
