Abstract: A filter element (10) comprises a porous, thick-walled, integral, self-supporting, resin impregnated and bonded fibrous, tubular filter structure (11) having a hollow core (15); an inner shell (20) of a first large pore size porous media adjacent the hollow core and forming the majority of the filter structure; and an outer shell (21) of a second small pore size porous media, finer than the first porous media and adjacent the inner shell, the first and second porous media being resin impregnated and bonded. A method for the manufacture of a porous, thick-walled, integral, self-supporting, resin impregnated fibrous tubular filter element comprises the steps of forming a hollow inner shell of a first large pore size porous media; forming an outer shell of a second small pore size porous media, onto the inner shell, finer than the first porous media; impregnating the inner shell and the outer shell with a resin binder; and curing the resin to form an integral, self-supporting, resin impregnated and bonded fibrous, tubular filter element.

Title: Method of seam closure for sheet transfer and other paper processing belts
Inventor: MILLER LAWRENCE G
IPC: D21F3/00
Filed: 1995-06-08
Granted: 2007-02-06
Abstract: Methods for closing a seam in a paper processing belt having a coating of polymeric resin material require the covering of the seam on the uncoated side of the belt with an encapsulating material, so that the seam will have compression properties substantially identical to those of use of the remainder of the belt. In one method, a viscous paste obtained by mixing a polymeric resin material with a blowing agent is used. Following installation of the fabric, or belt, on a paper machine by closing its pin seam with a pintle, the seam region on the non-paper side of the fabric or belt is impregnated with the viscous paste. The seam region is then heated to a temperature to activate the blowing agent and to create a foam from the paste. The foam fills voids in the seam region, and may pass out through the slit in the coating over the seam. Raising the temperature further cures the foam and may glue the slit closed. In other methods, a pre-foamed polymeric resin may be used to impregnate the seam region, or the seam region may be covered with a solid foam strip of a polymeric resin or a fibrous strip of fibrous batt material, either of which may be secured to the seam region by an adhesive. In each case, the belt so seamed may be used as a transfer belt or long nip press (LNP) belt, or in other paper processing applications.

Title: Lift plant
Inventor: FRIEDLI PAUL
IPC: B66B1/14
Filed: 1995-08-17
Granted: 2006-03-28
Abstract: This equipment enables an implicit input of destination calls in lift plants. An information transmitter (1) after a corresponding enquiry sends data (6) to a recognition device (5). These data (6) can contain direct information about the desired destination storey or serve for identification of the lift user and thus enable an access to the information, which is filed in a storage device (8), about the destination storey. The storage device (8) is accommodated in a processing unit (9) of a lift control (10). The communication between the recognition device (5) and the information transmitter (1) takes place by means of radio frequencies. With the aid of the obtained data (6), the destination storey is evaluated in the processing unit (9) and fed to the lift control (10). The allocation is made known to the passenger on a display (18). The process of the call entry takes place automatically, contactlessly and independently of the orientation of the information transmitter (1), i.e. it need not be visible for the recognition device (5). An input equipment (19) is mounted for changing the storey proposed by the processing unit (9).

Abstract: A tire separation system has a cutting head and a press for separating treads from rims of solid rubber tires. The cutting head has an annular blade with a blunt edge for cutting and tearing the rubber from the rim of the tire. Three spoke blades are spaced apart around the annular blade for cutting the diameter of the tread into sections. The rim drops through the annular blade to a conveyor, while the tread sections fall away to tread conveyors. The tires are brought from storage on a tire conveyor. The press has a hydraulic cylinder driving a piston with a jaw-type clamping mechanism for picking up tires. The cylinder is on a carriage that is movable from over the cutting head to over the tire conveyor for picking up tires to bring them over the cutting head for separating.

Title: Method of determining inflow rates from underbalanced wells
Inventor: ALEXANDER LLOYD G
IPC: E21B47/06
Filed: 1996-05-29
Granted: 2001-08-07
Abstract: A method is provided for determining the inflow rates of gas and liquid upon completion of an underbalanced well. The casing is placed, blocking fluid communication between the well and the formation. A tubing string is run in, forming an annular space and a tubing bore. The well is conditioned by removing sufficient liquids to create an underbalanced state and leaving a gas-filled space above any residual liquid. The volume of the gas-filled space in the annular space and the tubing bore is determined. The well is perforated, opening communication between the well and the formation. Pressure within the tubing bore and annulus is measured as a function of time.  The rate of change of pressure is dependent upon the nature of the incoming fluid; be it gas or liquid. From the above, the rate of incoming fluid can be established as a function of the volume of the gas-filled space and the rate of change of pressure. The inflow rates of solely gas or solely liquid may be determined whether substantially all the liquid is removed during conditioning or only some of the liquid is removed.

Title: Variable length coded data transmission device
Inventor: ADACHI SATORU
IPC: H04N7/52
Filed: 1996-06-28
Granted: 2001-07-03
Abstract: If a variable length code is caused to have a pseudo fixed length and transmitted in that condition, possible adverse effects due to out-of-synchronization attributable to code errors can be prevented, but it becomes difficult to enjoy this advantage in case an object to be fixed in length includes a block or blocks of variable length codes whose bit length is remarkably long. An object of the present invention is to obviate such a disadvantage as just mentioned. That is, for the transmission of variable length coded data blocks, a threshold arithmetic calculation circuit (9) obtains a threshold from an average of the bit lengths of the variable length coded data blocks for each group of such block., and the judgment circuit (10) makes a judgment as to whether or not those variable length coded data blocks have bit lengths exceeding the threshold of the block group to which such data blocksbelong. Then, a block divider circuit 11 divides the variable length coded data blocks having bit lengths exceeding the threshold into blocks having small bit lengths. Each block thus obtained is fixedly equalized in bit length to an average length level and in that condition.

Abstract: At pressures over 1000 psia, it is advantageous to add to natural gas an additive which is a C2 C3 and C4 hydrocarbon compound, CO, NH3 or HF or a mixture of such additives. Above a lower limit (which varies with the additive being added and the pressure), this results in a smaller Z factor, or (M w.Z) product, representing increased packing of molecules, and therefore leading to a decrease in the amount of power needed to pump the mixture or to compress it.

Title: Multi-channel predictive subband coder using psychoacoustic adaptive bit allocation
Inventor: SMYTH STEPHEN M
IPC: G10L/
Filed: 1996-11-21
Granted: 2002-07-09
Abstract: A subband audio coder (12) employs perfect/non-perfect reconstruction filter s (34), predictive/non-predictive subband encoding (72), transient analysis (106), and psycho-acoustic/minimum mean-square-error (mms e) bit allocation (30) over time, frequency and the multiple audio channels to encode/decode a data stream to generate high fidelity reconstructed audio. The audio coder windows (64) the multi- channel audio signal such that the frame size, i.e., number of bytes, is constrained to lie in a desired range, and formats the encoded data so that the individual subframes can be played back as they are received thereby reducing latency. Furthermore, the audio coder processes the baseband portion (0-24kHz) of the audio bandwidth for sampling frequenci es of 48kHz and higher with the same encoding/decoding algorithm so that audio coder architecture is future compatible.
