Abstract: ABSTRACT           A message device operable with a telephone is provided.   The  device  includes  a  connection  and identification circuit which receives incoming telephone call signals generated from a remote telephone that are transmitted over the public telephone  lines.   The identification circuit monitors the number of call signals received between a connection and subsequent disconnection of  a remote  telephone  thereto  and conditions the apparatus to a stand-by mode when the number of incoming calls received is equal to a pre-determined number.   When the device is in the standby mode,  the circuit monitors the telephone lines for further incoming call signals generated by the remote telephone.   If a second pre-determined number of incoming call  signals  are received within a pre-determined amount of time after the first disconnection of the remote telephone from the circuit, the device is conditioned to an operating mode.   A recording and reproducing function are provided and are operable when the device is in the operating mode to allow the party using the remote telephone to record messages or to listen to pre-recorded messages.   A password detection circuit is also included which inhibits the operation of the recording and reproducing function when the device is in the operating mode until a proper password is received from the remote telephone.

Title: Multiplex transmission system
Inventor: MUTO MAKOTO
IPC: H04L69/40
Filed: 1988-11-29
Granted: 1993-04-13
Abstract: ABSTRACT OF THE DISCLOSURE    A multiplex transmission system, in which a node as a transmission node transmits data frame by frame to a transmission path, and a plurality of other nodes, as reception nodes, returns a reception acknowledgment signal to the transmission path upon proper reception of the frame of data.  Each of the reception nodes which properly received the frame returns the reception acknowledgment signal specific thereto to that division of a reception acknowledgment signal area in the frame which corresponds to this node.  Each node discriminates the success/failure of signal transmission, by comparing the information registered beforehand in its reception acknowledgment signal table with the information in the reception acknowledgment signal area.  When the information of  the reception acknowledgment signal table does not coincide with that of the reception acknowledgment signal area, the transmission node re-transmits the frame and the reception acknowledgment signal tables of all the nodes are updated.  The system can not only effect the addition and deletion of multiplex nodes easily without requiring the change of scale of the circuit of the system, but also discriminate trouble for each of the multiplex nodes.

Abstract: ANTITACHYARRYTHMIA PACEMAKER USING PRE-EJECTION PERIOD TO DISTINGUISH PHYSIOLOGIC FROM PATHOLOGIC TACHYCARDIA               ABSTRACT OF THE DISCLOSURE A   cardiac    stimulator   apparatus    for    effecting cardioversion  or defibrillation  in  the  event  of  pathologic tachycardia or  ventricular fibrillation  in which  the  rate  of heart depolarization signals is compared to a predetermined heart rate  value   indicative  of  the  onset  of  tachycardia  while, simultaneously, the heart's pre-ejection  period is  monitored to sense whether  an increase  in heart rate above the predetermined value is accompanied by  a decrease  in the  pre-ejection period. If not,  a  pathologic  rather  than  a  physiologic  episode  is diagnosed and a cardioversion  pulse protocol  is initiated.   By also  monitoring  the  mechanical  pulse  of  the  heart,  if  an inordinately  high heart  rate is  accompanied by  a low  or non-existing mechanical  pulse, ventricular fibrillation is diagnosed and the cardioverter is triggered  to shock  the heart  back into sinus rhythm.  If the mechanical pulse rate tracks the electrical rate  of  depolarization,  tachyarrythmia  is  confirmed.     The diagnosis may  be further  confirmed by  taking into  account the rate at which the heart rate increases.

Title: Variable-gain ac amplifier
Inventor: BENZ PAUL
IPC: H03G1/00
Filed: 1989-04-21
Granted: 1993-06-15
Abstract: ABSTRACT         A broadband amplifier having controllable amplification and an extremely high upper frequency limit includes a single-gate field-effect transistor arranged in a common-source configuration and a variable voltage source connected to the drain terminal of the single-gate field-effect transistor.  The gate terminal of the single-gate field-effect transistor is connected to RF input signals to be amplified.  The drain current ID is varied by a controllable voltage; this voltage changes the gain but does not change the low resistance during the controlled process.  The transconductance S of the single-gate field-effect transistor is portional to the square root of the drain current ID.  Thus, two or more single-gate field-effect transistors can be connected in series to form a multiple-stage amplifier without interfering with one another.

Abstract: CONTROL SYSTEM FOR FORCED COMBUSTION AIR                  HEATING APPLIANCE                 ABSTRACT OF THE DISCLOSURE          A control  system,  for  a  gas-fired,  forced combustion air heating appliance,  controls operation of  a  combustion  air  blower  and a  gas  valve  as  a function of signals from a thermostat,  a combustion air proving sensor switch,  and a gas valve control relay.  When the thermostat demands heat, the control system first checks the status of the combustion air sensor  switch  before  starting  the  combustion  air blower.    If   the   combustion  air   sensor   switch indicates  that combustion  air  is  being  delivered before  the  combustion  air  blower  has  started,  the control   system   immediately   halts   the   ignition sequence.   If  the  combustion  air  sensor  switch  is functioning properly, the ignition sequence continues and  the  control  system  checks  the  status  of  the contacts  of  the  gas  valve  relay.   If  the  relay contacts which power the gas valve are already closed before  the gas valve relay coil  is  energized,  the control system halts the ignition sequence by turning off the combustion air blower, causing the combustion air sensor switch to open and shut off power to the gas valve. 0725f                                          19A88

Patent DK-161844-C (DK)
Inventor: TEGLUND LARS
IPC: E03F5/10
Filed: 1979-11-22
Granted: 1992-01-27
Abstract: A liquid-plug-creating device includes a collection tank or basin into which liquid flows such as the outflow from sanitary appliances. From the outlet at the bottom of the tank a riser extends upwardly at an acute angle to the horizontal. At the opposite end from the tank outlet, the riser terminates in a bend which reverses the direction of flow through the riser into a downwardly extending vertical pipe. A U-shaped piece of pipe with a horizontal outlet is connected to the lower end of the vertical pipe and provides a special form of trap. When the tank and the riser are completely filled with liquid, any additional liquid added exceeding a minimum flow, causes a liquid seal to be formed in the piece of pipe at the lower end of the vertical pipe. The excess flow creates a vacuum in the vertical pipe which sucks the liquid through the riser out of the tank in the manner of a siphon. The liquid immerges from the device in the form of continuous plugs with high kinetic energy content. The device permits the use of small-diameter pipes in house drainage systems while assuring the required self-cleansing effect, even if water-conserving flush toilets are connected to the device. Other fields of application of the device are irrigation and the metering of liquids in batches.

Abstract: A constant load and constant contact force snap-action switch (Figure 1) having a normally-closed movable operate contact (18) on a flipper blade (20) which has a compression strip (20c) that snaps through an S-curvature to a reverse buckled state to trip the operate contact open. The flipper blade is coupled through an insulating cap (26) to the leaf spring mounted movable alarm contact (22) to close the latter at the same time. A return spring (36) biased reset lever (32) resets the operate contacts on depression down a first amount, opens the operate contact without closing the alarm contacts on depression down a second amount for stop purposes, and trips the operate contacts open on lifting upwards for test purposes. On reset, lost motion in the coupling cap (26b) knocks the alarm contact open if welded. A selector (38) is settable to select any of three functions for the reset lever, (1) reset-stop-test, (2) auto reset stop, or (3) reset test.
