Title: Lateral and circumferential register adjustment system for a rotary printing machine
Inventor: KNAUER PETER
IPC: B41F13/14
Filed: 1990-05-23
Granted: 1993-04-13
Abstract: ABSTRACT OF THE DISCLOSURE.      To provide a clean operator side (I) of a printing machine, the circumferential and lateral register adjustment of a plate cylinder (20) is located on the machine or drive side (II) of the machine and is formed by  a special gearing arrangement; a first gear (12) which is rotatable on an axially shiftable stub shaft (19) of the plate cylinder by being positioned on a bearing thereof, is driven from a second  gear    (9) which may also drive an offset blanket cylinder (18).  The first gear is in meshing engagement with a dual gear, having third and fourth gearings (16, 15),  the first, second and third gears being spiral or inclined, and the fourth gear (15),which meshes with an axial fixed fifth gear (13) splined to the shaft of the cylinder (19), 19 likewise formed with axial teeth.  The combined third and fourth gears can be shifted axially, thus causing rotation of the fourth gear by the "thread" type engagement of the third gear with the first gear, which rotation is transferred to the fifth gear and hence to the plate cylinder; in addition, the axial position of the plate cylinder is independently adjustable by a spindle (29) moving the stub shaft without transmitting rotation thereto or receiving rotation therefrom.

Granted: 1998-07-14
Abstract: Apparatus is provided for recording and reproducing video and audio signals on a record medium, wherein the audio signal may be of at least two different types subjected to respectively different types of audio processing.  A recording section produces frequency modulated audio signal components and selectively adjusts the level of at least one FM audio signal component during the video blanking intervals as a function of the type of audio signal being modulated.  Then, the FM audio signal components and the video signal are combined and recorded.          A reproducing section separates the reproduced FM audio signal components from the reproduced video signal and detects the level of at least one separated FM audio signal component during blanking intervals.  The FM audio signal components are demodulated and processed pursuant to a selected type of audio processing dependent upon the detected level of the FM audio signal component.

Title: Low noise toilet tank valve
Inventor: SCHOEPE ADOLF
IPC: F16K47/02
Filed: 1990-08-29
Granted: 1993-10-19
Abstract: LOW NOISE TOILET TANK VALVE                     ABSTRACT OF THE DISCLOSURE          A  toilet refill valve is described for refilling a water  closet  after  each  flushing, which produces minimal noise  during the refill process. The valve includes a valve device  which  can  open  to pass water to a vertical outlet tube  that  empties  into the bottom of the water closet. An anti-siphon  air tube near the top of the outlet tube has an upper  end  open  to  the  atmosphere and a lower end facing downwardly  along  the  outlet  tube.  A  restriction in the outlet  tube  below  the  air tube, causes water to fill the outlet  tube  and  at least the bottom of the air tube for a water  inlet  pressure  of  at least 20psi. The water at the bottom  of the air tube prevents air from being dragged into the  downwardly  facing  air  tube,  to avoid the noise that would  result from such air flowing through the air tube and bubbling out of the bottom of the outlet tube.

Title: Ostomy device with improved coupling system
Inventor: EDWARDS JOHN VICTOR
IPC: A61F5/448
Filed: 1991-05-15
Granted: 2003-07-22
Abstract: In the first embodiment, the faceplate coupling ring is of conventional design and includes an axially extending rib with a radially outwardly extending rim and a radially inwardly extending deflectable sealing strip. The pouch coupling ring includes inner and outer spaced walls, forming a channel for receiving the rib. First and second protrusions extend inwardly from points on the interior surfaces of the walls proximate the ends thereof. The first protrusion cooperates with the rim and the second protrusion cooperates with the tip of the sealing strip, to securely retain the rib within the channel. The walls of the channel have reduced thickness and are easily deflectable as the rib is inserted into the channel, such that coupling of the rings is facilitated but decoupling requires the conventional amount of force due to the second protrusion. In the second embodiment, the deflectable sealing strip on the faceplate coupling ring is replaced by a rigid flange which cooperates with the second protrusion to substantially increase the decoupling force.

Granted: 1994-10-25
Abstract: A vacuum assisted toilet is described wherein a vacuum is applied to a toilet bowl outlet during flushing, which avoids malfunctions that could allow sewer gas to escape,  and which uses flushing water effectively.   The toilet bowl outlet includes upper and lower trap devices (40,44, Fig. 5) coupled by a trapway (42), with the lower trap device forming an unobstructed air passage when no water is moving therethrough but which includes a trapping region (64) that completely fills with water and forms an airflow barrier during  flushing.   The vacuum source  includes a container (72, Fig. 1) in the toilet tank, with the container fixed in place in the tank to lie stationary therein, and with an  ordinary  flush  valve  (23)  lying  outside  the container, so substantially the only part of the toilet that moves during flushing is the long developed and reliable flush valve.  A baffle (110) separates a first tank portion (114)  which holds the container and flush valve,  from a second tank portion (116) which holds an inlet valve.  The top (118) of the baffle lies a plurality of centimeters below the high water level (16), so that a lot of water passes into the toilet bowl at the beginning of flushing.

Title: Dc/dc power transformer
Inventor: LALANDER MAGNUS
IPC: H02M5/27
Filed: 1990-11-02
Granted: 1998-07-07
Abstract: The DC/DC power transformer is an arrangement for direct transformation of high electric powers from one DC voltage level to another DC voltage level without intermediate AC voltage network. The DC voltage is today basically used for transmission of high electric powers at long distances.  The DC voltage levels for these transmission are normally high. The DC/DC power transformer allows several DC voltage levels to be used in one and the same DC voltage network. The principle for this arrangement is that the valve windings (43, 45) from one or several converter transformers (47) are connected to two valve bridges, which generate opposing cyclically variating magnetic flows in the transformer cores (44). One of the valve bridges is operated as an inverter (49) and the other as a rectifier (46) and in this manner the power is transformed from one DC voltage level (Ud1) to another (Ud2). At the high voltage levels for which the invention is intended the leakage inductances in the transformers will be high as a consequence of the insulation levels and due to this special arrangements must be made in order to commutate the magnetic energy from one phase of the transformer to another without creating great losses. The arrangement is proposed in a line commutated alternative (figure 5) and in a selfcommutated alternative (figure 4). The first utilizes a third AC voltage reference winding (A3, B3, C3 in figure 5) for this commutation.  In the second alternative an external over the bridge connected capacitor (48 in figure 4) is utilized for this commutation purpose. Both alternatives may be designed galvanically insulated or in autocoupling (figure 10).

Title: Inertial filtration external dilution probe
Inventor: TOMLIN ROBERT L
IPC: G01N33/00
Filed: 1992-08-27
Granted: 1996-06-25
Abstract: An inertial filtration dilution probe for sampling stack gas for analysis.  The probe is based on a body having a central chamber passing from a first end of the body to a second end.  One end of the central chamber is connected to a sampling tube to be inserted into a stack and the opposite end of the body has a port which is adapted to be selectively connected to a source of calibration gas or blowback gas.  A filter divides the central chamber into an inlet portion and an outlet portion, with the sampling tube and port connected to the inlet portion.  The probe further comprises a dilution eductor joined to the body, for mixing filtered stack gas with dilution gas and comprising an inlet for dilution gas, an outlet for diluted gas and a vacuum cavity therebetween.  A sample passage within the body connects the outlet portion of the chamber to the vacuum cavity and a heating means encloses the body and eductor.  The probe allows more accurate calibration of the gas analysis, since the calibration gas follows in the same path as the stack gas.
