Title: Pallet storage system for storing cylindrical articles and pallet for use therein
Inventor: KRAUS ROBERT T
IPC: B65D19/38
Filed: 1990-03-09
Granted: 1998-10-27
Abstract: A system for storing cylindrical objects includes at least two article supporting pallets having mating projecting noses and oppositely disposed recesses. The pallets comprise at least upper deck boards for supporting the articles on the one hand and engaging a supporting surface such as a floor on the tops of risers or other vertically disposed restrainers on the other hand. The projecting noses and opposed recesses are preferably tapered for ease of alignment. The pallet is dimensioned so that the pallet has a width dimension approximating two and three quarters the diameter of a selected article, a length dimension approximating two diameters of the selected article and the nose projects approximately one half the diameter of the selected article. The system also encompasses the use of a series of pallet sizes, wherein each pallet differs from the other by about 15 percent in size, which permits the user to achieve optimal storage density for a broader range of diameters for such articles.

Patent CA-2055410-C (CA)
Title: Composite bridge amplifier
Inventor: FRENCH JOHN BARRY
IPC: H03F1/02
Filed: 1991-11-13
Granted: 2001-04-03
Abstract: A composite bridge amplifier having four output metal oxide semi-conductor field effect transistors (mosfets) in a bridge configuration. The gates of the mosfets are controlled by an input signal which is amplified in a diamond differential amplifier phase splitter and voltage gain stage and then applied to the mosfet gates. The power terminals (sources and drains) of the mosfets receive a power signal which varies with the input signal at a level sufficient to maintain headroom above the output signal but to reduce power dissipation in the mosfets. The power signal is produced by a switch connected between a floating power supply and a filter and operated at e.g. 200 KHz. The switch is operated by a pulse width modulated (pwm) signal derived from the absolute value of the input signal. Because the power signal in effect tracks the output signal, little power is dissipated in the mosfets so that the amplifier can be made very compact. Because of the bridge configuration, only one switch, one floating power supply and one pulse width modulator are used, reducing cost. Feed forward compensation in the pulse width modulator varies the pulse width of the pulses operating the switch inversely with changes in the power supply voltage, allowing the floating power supply to be unregulated.
Patent CA-2055490-C (CA)
Inventor: FOOTE JERROLD L
IPC: A61F2/958
Filed: 1990-03-12
Granted: 1996-10-08
Abstract: An electronically controlled syringe sys-tem (14) for connection to a balloon catheter (10) or other balloon-type member and for auto-matically monitoring, displaying and recording inflation data when the syringe system (14) is used to inflate the balloon catheter (10) or other balloon-type member. A syringe (16) having a barrel (22) and a syringe plunger (24) is selec-tively operable to increase fluid pressure appli-ed to the balloon catheter (10) or other balloon member by sliding the plunger (24) further into the barrel (22). Positive pressure applied to the balloon catheter (10) or member can be released by withdrawing the syringe plunger (24) toward the rear of the barrel (22). A piezoresistive semi-conductor transducer (18) housed on the barrel (22) of the syringe (16) senses positive fluid pressure applied by the syringe (16). The elec-tric signal output by the transducer (18) is input to a controller (20) where the signal is digitally processed so as to derive and record therefrom electronic data representing the magnitude of applied fluid pressure, and so as also to derive the length of time that positive fluid pressure is applied and the elec-tronic data representing this information is automatically displayed and recorded. The controller (20) is also programmable to permit optional selection and input of various control parameters, such as a maximum positive inflation pressure that is to be ap-plied, maximum duration for applying positive inflation pressure, initialization of the date and time of an inflation procedure and/or retrieving and displaying inflation data previously recorded for any prior inflation of the balloon catheter (10) or other balloon member.

Title: Clock generation circuit for multistandard serial digital video with automatic format identification
Inventor: HERSHBERGER DAVID L
IPC: H04N5/06
Filed: 1992-03-24
Granted: 1998-06-09
Abstract: A voltage controlled reference oscillator (20) with a high Q and narrow tunability bandwidth produces an output oscillator frequency which is frequency divided (18) by four alternative constants to produce four different clock frequencies for four different digital video standards, D1 component at 270 MHz, NTSC D2 composite at 143 MHz, PAL D2 composite at 177 MHz, and a proposed new composite video standard that is to operate at a 360 MHz clock rate.  Automatic identification of which serial digital video is present is accomplished by having the clock generator (20,18) produce a clock signal at the frequency required by one of the video formats while a phase lock loop (90,26) attempts to lock onto the incoming signals at that frequency. If no lock occurs within a predetermined time interval, the clock generator (20,18) is made to produce a clock signal at the frequency required by a different one of the video formats and the phase lock (90,26) is attempted again.  This is repeated until a lock is attained.  Optionally, when a lock occurs, the video is tested (80) for validity within the format that is consistent with the clock frequency that produced the lock.

Title: Procedure for the preparation of microporous ceramic membranes for the separation of gas and liquid mixtures
Inventor: MAIER WILHELM FRIEDRICH
IPC: C04B41/81
Filed: 1992-05-11
Granted: 1997-11-04
Abstract: Gas and liquid separation with membranes has either been achieved by organic polymer membranes, which are limited by low temperature stability and a separation mechanism through adsorption or solubility in the membrane matrix, or by inorganic membranes, whose gas and liquid separation efficiency is limited by Knudsen diffusion. The membranes of this invention show a temperature stability up to 500 °C and a gas separation with separation factors better than the Knudsen limit.   Continuous microporous inorganic membranes of any desirable thickness can be prepared by e-beam evaporation of metal oxides on a support membrane, which has substantially larger pores than the metal oxide membrane.  It is advantageous when the support membrane consists of the same material as the microporous membrane.  Themembranes are of porous structure with a narrow pore size distribution of pores, where the majority of the pores have meters smaller than 1 nm.   The membranes can be used in all areas of gas and liquid separation, where the selective separation of smaller molecules from mixtures is desired (f.e. gas concentration by removal of water from natural gas, hydrogen from synthesis gas). The membranes can also be used for the concentration of aqueous solutions (fruit juices with retention of aroma compounds, vitamines and other compounds important for the flavor and nutritional value of the juice; biological liquids like lymphe, blood, or others with retention of valuable compounds including small peptides, hormones, antibiotics and others) and for the concentration of organic solutions with retention of molecules larger than the solvent including oligomers and polymers.  The membranes can also be used for the concentration of waste water with retention of organic contaminants like phenol resins and coal oil at coking plants.  If the membranes have been made catalytically active, the membranes can also be used for the selective and poison resistant conduction of heterogeneously catalyzed three phase reactions by having the reaction gas diffusing through the catalytically active membrane to react at the other side of the membrane with the liquid, consisting of molecules too large to penetrate the pores.
