Title: Water extraction method and control for automatic washer
Inventor: NYSTUEN ARNE M
IPC: D06F33/40
Filed: 1988-04-13
Granted: 1992-08-18
Abstract: ABSTRACT      A method and control for an automatic washer is provided in which moisture extraction from a  fabric  load  is  controlled  by extracting the moisture at  increasingly faster levels of basket rotation. Initially the basket is rotated relatively slowly and it is subsequently rotated at successively faster speed levels, each increase occurring after substantially all of the moisture has  been  removed  which  is  removable  at  a  given  speed  level.          Inertia of the fabric load is measured to determine the amount of incremental moisture removal. Use of such a method substantially reduces  the  force  applied  to  the  fabric  load  during  the centrifugal extraction resulting in less wrinkling of the fabrics.                             _26_

Abstract: Abstract A seat (2) is mounted pivotably about a first axle (A1) on the stand (1) of the chair.  The seat frame (8) is connected to a second axle (A2) which is fastened to the backrest (3) behind the backrest (3) at a horizontal distance from the latter and at a vertical distance from the first axle (A1).      The backrest (3) produced from an elastically resi-lient material, when deflected out of its vertical posi-tion, causes the second axle (A2) to move over an arc of a circle of radius A1 - A2; the rear seat portion ad-jacent to the backrest (3) is also lowered corresponding-ly thereby. The backrest (3) extending over the entire height of the chair forms with its lower portion an in-tegral component of the chair stand (1).      In comparison with the known complicated and heavy backrest/seat adjustment mechanisms, a cost-effective and lightweight construction, but one which fully satisfies modern ergonomic requirements as regards sitting comfort, is proposed here.

Granted: 1991-05-07
Abstract: ABSTRACT            Mixing Device The mixing device is used for mixing multicomponent materials or for homogenizing compositions which are contained in a cartridge  (10)  which is closed by a piston (15) having a passage opening (19). The latter is primarily closed by the shaft (22)  of a mixing member (20). Said shaft (22) may be coupled to a rod (23). By a drive or by manual operation, the rod (23) may be rotated and moved axially at the same time. While the piston (15) stays, where it is, the mixing member (20) is moved through the cartridge (10). Upon termination of the mixing operation, the mixing member (20) is locked at the piston (15) by a holding member (32) in order to unscrew the rod (23) from the mixing member.  Subsequently,  the cartridge may be inserted into a squeezing tool in which the piston  (15)  is advanced for squeezing out the compositon.            (Fig. 1).

Abstract: ABSTRACT OF THE DISCLOSURE        A digital  transmitter       with an analog sensor        uses  an  integrating  analog-to-digital converter       to digitize  the analog signal from  the  sensor      .   The  A/D converter produces  a  digital  output  which  is  a  continuous, non-rezeroed integrated average of the analog signal, so that the integrated average of the digital output over  time  does  not  contain  inherent  quantization errors.    A  microcomputer  system         digitally filters the signal from the A/D converter     , and then uses the digitally filtered signal  to produce the  transmitter  output  signal.   By  varying  the response  time  of  the  digital  filter       ,  the response time and resolution of the transmitter can be varied.

Title: Transport of molecules across tissue using electroporation

Granted: 1994-01-18
Abstract: TRANSPORT OF MOLECULES ACROSS             TISSUE USING ELECTROPORATION     Abstract of the Disclosure An electrical process for enhancing and/or controlling transport of molecules across tissue such as human and animal skin is disclosed.  The process involves the use of a high voltage, short duration electrical pulses on the tissue surface to produce electroporation.  Once this effect has oc-curred, concentration, pressure or temperature gradients, or iontopheresis can be used to move molecules across the tissue.  The process can be repeatedly applied without producing undesirable tissue damage or can be used to purposely cause highly limited tissue damage for the purpose of providing a desired, relatively long term molecular transport pathway.  The occurrence of the electro-poration effect can be detected by monitoring the tissue for a reversible electrical breakdown, which, along with an enhanced tissue permeability, is the characteristic effect of electroporation.
