Title: Improved control of fns via pattern variations of response emg
Inventor: GRAUPE DANIEL
IPC: A61N1/36
Filed: 1989-11-29
Abstract: ABSTRACT OF THE DISCLOSURE Paraplegic patients and certain other paralyzed patients who suffer from an upper motor unit spinal cord injury and undergo FNS (Functional Neuromuscular Stimulation) experience muscle fatigue within a time span that is usually shorter than is normal, but have no sensation of this fatigue due to paralysis.  When FNS is used functionally, as is its implied purpose, to stand and walk, the patients need the support of a walker or canes or elbow crutches, and are unable to manually adjust FNS levels or pulse widths to compensate for that fatigue, since the time for this adjustment is exactly when the patients cannot divert attention and hands to anything else.  Under FNS, the stimulated muscles produce an EMG (electromyographic) signal at the stimulated site, in response to that stimulation.  This response-EMG undergoes pattern changes with the progression of fatigue.  The present invention employs pattern recognition of the response-EMG where pattern parameters are identified whose variation with time is a function of the progression of muscle fatigue.  This time variation is employed to adjust FNS pulse width and/or pulse level to compensate for that fatigue in an automatic manner that does not require the patient's attention.  The present invention also provides for diagnostic uses of this pattern recognition, and for muscle contractions other than for standing or walking.

Title: Method and device for the protected transmission of data
Inventor: BUHN WILLI
IPC: G09C1/10
Filed: 1990-09-17
Abstract: ABSTRACT      A ciphering device (1) encodes the original data and converts it into signals for an output device (5) that creates a document (6, 10) out of them. This document is fed into a sending device (12) that scans the data (7) line by line and converts the result into signals that are transmit-ted to a receiving device (13) via a transmission link (14). The receiving device (13) produces a copy (15) of the docu-ment (6, 10) out of the transmitted signals, which is fed into a reading device (17). This device converts the data into signals for a deciphering device (18) which decodes the data and converts it into signals for an output device (20). From them, the output device (20) restores the original data and makes it available for further processing.     The transmitting device (12), the receiving device (13) and the transmission link (14) form a telecopying system. The encoding of data (7) is done by using a code that is insensi-tive to transmission errors of the telecopying system and, in particular, to distortions in the line feed direction. The code is preferentially binary with logical values contrasting in brightness and/or color, for instance it is a bar code with bars (9) parallel to the line feed, and it can be read be a reading device (17).     The parts of the system in a transmitting-end device or a receiving-end device are preferentially integrated.                                (Single Figure)

Title: Syrup delivery system
Inventor: LANG-REE ARNE
IPC: B67D1/00
Filed: 1990-12-11
Abstract: ABSTRACT OF THE DISCLOSURE       A syrup delivery system including a plurality of open-top, sturdy plastic containers and syrup bags.  Each bag is positionable in a separate container with the bag spigot thereof extending accessible out through a container end opening.  The open gridwork bottom of the container slopes to the container end opening so that the syrup in the bag can drain more completely out through the spigot with the container supported on a flat level surface.  The containers have top locking posts, bottom stacking feet, and undulating-like sides.  With the containers aligned so that their end openings face the same direc-tion, the containers can be stacked one on top of the other with the posts of the bottom container engaging up into the feet of the top container.  To unstack, the top container is tilted forward, the posts and feet thereby disengage, and the tilted top container easily slid down the sloping front lip of the lower container.  To nest the con-tainers, the top container is rotated 180 degrees about a vertical axis and the containers, due to their undulating sides, nest together in a relatively compact two-to-one nesting ratio.  In the nested position the posts of the bottom container extend up into openings in horizon-tal support surfaces positioned mid-way up  the sides of the top container.

IPC: F16K21/10
Filed: 1990-12-27
Abstract: ABSTRACT     A  water tap, which comprises a housing having  an outer  cap  mounted  on its water supply  outlet  to  secure therein a water intake cap, a control shaft, a control  bolt and a ring-shaped element.    The control shaft comprises an upper circular groove with a stop cock mounted thereon,  and a  lower  circular  groove with  a  ring-shaped  water  seal mounted thereon.    When the control shaft is pushed upward, water  flow is permitted to pass through  water inlet  holes on  the  water intake cap for discharging out of  the  outer cap.    When  pressure force is released  from  the  control shaft, water flow is accumulated  in the inner space of  the water  intake cap and the inner space of the  control  shaft permitting water pressure to force the control shaft to move downward  so  as to block up water supply.  The  control bolt  can be turned to move up and down inside  the  control shaft  so as to control the flow rate through  the  through-holes around the periphery of the control shaft.

Title: Discharge tube for series gap ignition apparatus
IPC: H01J17/04
Filed: 1991-07-09
Abstract: ABSTRACT OF THE DISCLOSURE      The discharge tube has an insulating tube formed into a hollow cylinder with one end open and the other closed.  An anode electrode, which is formed as a flanged electrode, is hermetically fitted to the open end of the insulating tube and a cathode electrode, which is formed as a bar electrode, is embedded in the closed end of the insulating tube so that only the front end surface of the bar electrode faces the interior of the insulating tube.          This construction allows no redundant space within the insulating tube other than the discharge space, so that the discharge tube can be minimized in size.  This construction also permits a discharge only between the front end of the bar electrode and the inner end of the flanged electrode, stabilizing the electron emission passage or discharge path and therefore the discharge voltage.
