Title: Biodisintegrable thermoplastic resin foam and a process for producing same
Inventor: TOKIWA YUTAKA
IPC: C08J9/00
Filed: 1990-12-20
Granted: 1995-01-24
Abstract: Title:    A Biodisintegrable Thermoplastic Resin Foam and a Process for Producing Same ABSTRACT OF THE DISCLOSURE          A biodisintegrable thermoplastic resin foam and a process for producing same are disclosed, the biodisintegrable thermoplastic resin foam being comprised as a substrate thereof a mixed resin comprising 5-40 weight % of a thermoplastic resin decomposable by microorganisms and 95-60 weight % of a thermoplastic resin not decomposable by microorganisms and being characterized in that the individual aerial cells constituting the foam have an average cell wall thickness of 1-100 µm and an apparent density of 0.5 g/cm3 or less than 0.5 g/cm3.  The biodisintegrable thermoplastic resin foam is easily disintegrable after disposal in an environment where microorganisms exist so that it can be reduced in bulkness and gives no harmful effect on the life of natural plants and animals.  The foam incorporated with a filler can be promoted in disintegration by microorganisms.  Thus the present invention affords an effective means for solving various problems in the treatment of disposed materials.

Granted: 1993-12-28
Abstract: ABSTRACT     A fuel-fired water heater has a plurality of bottom end legs which hold the bottom end of the heater a few inches above the floor,  and a fuel burner positioned directly above a combustion air inlet in the bottom end of the heater body.   To assure that all combustion air delivered to the burner is taken from a height at least 18" above the floor, a bottom and portion of the water heater  is  positioned  within  a  floor  supported,  horizontally enlarged drain pan which vertically extends to at least 18" above the floor.  In one embodiment thereof, the drain pan has an open top through which combustion air enters and is drawn downwardly to the bottom air inlet of the heater, and in another embodiment the drain pan top is closed off and combustion air is ducted into the pan from a remote,  higher location.   The pan has an outlet fitting which may be connected to a pipe or hose to drain away any water leaking from the water heater, or from closely adjacent piping and/or fittings connected thereto.

Title: Adaptive bandwidth moving average filter
Inventor: MOHTASHEMI ABDI
IPC: G06F17/18
Filed: 1991-10-01
Granted: 1995-09-19
Abstract: A  software  filter  is  described  which  operates  a computer to perform a moving average filter method. The method comprises designating an  initial  filter constant  to  control  the  filter  response  time; maintaining a moving average signal value; finding a difference value between the moving average signal value and each new signal sample amplitude before the new signal sample amplitude is included in the moving average signal value;  updating the running average signal value by adding to it, at a time of each new signal  sample,  a value  calculated by dividing the difference value found for a new signal sample by the initial  filter  constant;  and  when  a  sequential plurality of the found difference values manifest an identical  polarity,  dividing  the  initial  filter constant by an integer  factor to create a reduced filter  constant  which  thereby  reduces  the  filter response time.  When, by contrast, a found difference value  manifests  a  different  polarity   from  an immediately  preceding  found  difference  value,  the filter constant is multiplied by an integer factor to increase its value, not to exceed a maximum value, so as to increase the filter response time.

Title: Screen element
Inventor: EINODER NORBERT
IPC: D21D5/16

Granted: 2005-05-10
Abstract: The invention concerns a screen element, in particular a screen basket to sort/classify fibre suspensions, consisting of parallel bars, between which slot-shaped screen openings are formed. The screen opening, formed between two adjacent screen bars, is at least partly limited by parallel walls, with the parallel side wall of the subsequent bar extending further in the direction of flow in the screen opening than the parallel side wall of the preceding bar. It has been proven that, with the present screen element, the wear behaviour of the bars and the resistance to flow can be favourably influenced.

Granted: 1997-02-11
Abstract: An improved control, which dynamically adjusts the shift control parameters in response to the driving habits of the operator, as judged by an indication of the average peak acceleration during specified operation of the vehicle.  To determine the indication of average peak acceleration, the longitudinal acceleration of the vehicle is continuously determined in the course of vehicle operation.  The peak acceleration values occurring in successive ratio-dependent time intervals are identified and accumulated to form cumulative and average peak acceleration terms.  The average peak acceleration term is used to form a dynamic shift factor which is used to ratiometrically schedule the shift pattern, line pressure and desired shift time between predefined Normal and Performance values to provide a continuum of shift control parameters uniquely suited to the driving style of the operator of the vehicle.

Filed: 1992-02-24
Granted: 1997-04-08
Abstract: A method and apparatus is provided for transmitting spread spectrum signals.  The transmitter (242) receives data symbols (214). Subsequently, the transmitter (242) splits (244) each particular set of two received data symbols (214) into a first and second array of data symbols (252, 254) according to either of two algorithms.  The first algorithm includes providing both data symbols (214) of the particular set to the first and second array of data symbols (252, 254) and the second algorithm includes providing one of the data symbols (214) of the particular set to the first array of data symbols (252) and the other of the data symbols (214) of the particular set to the second array of data symbols (254).  Subsequently, the transmitter (242) determines particular channels to transmit the first and second array of data symbols (252, 254) by spreading (232, 234) the first and second array of data symbols (252, 254) with a predetermined length Walsh code (216).  The transmitter (242) accommodates a variable number of data channels by selecting a particular algorithm from a group consisting essentially of a first algorithm and a second algorithm and setting the predetermined length Walsh code (216) in response to the particular algorithm selected.
