Patent EP-0291954-A3 (EP)
IPC: H04N9/877
Filed: 1988-05-18
Abstract: A video signal reproducing apparatus, such as 
a video disc player, equipped with a field memory (5) for 
special reproduction such as still-picture reproduction. 
The video signal writing-reading period for the field 
memory is set to a value which is the color subcarrier 
period multiplied by an integer, is also the horizontal 
synchronizing period multiplied by an integer and is 
further approximate to one field period to the greatest 
possible extent, to thereby eliminate the discontinuity 
of video signals due to the track jumping action of the 
pickup.

Title: Pneumatic shock absorber
IPC: F16F9/02
Filed: 1988-10-05
Abstract: The invention proposes a pneumatic shock absorber with a piston (10) displaceable in a cylinder (11) and having a piston rod (14) which projects from the latter. Via a non-return valve (25) which forms an inlet, a pressure space (12) situated in the cylinder (11) and bounded by the piston (10) is connected to an external pressure source (P). An outlet valve (19) which releases the compressed air during a damping movement of the piston has a valve piston (41) which is guided in a sealed manner in a valve chamber (29) and divides the latter into two sub-chambers (32, 33). The first sub-chamber (32) connects a passage (20) leading to the pressure space (12) to an outlet passage (35), the connection being interruptable by means of a valve seat which can be closed by an end face of the valve piston (41) subjected at least in part to the pressure of the pressure space (12). The second sub-chamber (33) is connected to the pressure space (12) or to the pressure source (P). Finally, a spring (39) which presses the valve piston (41) against the valve seat (36) is provided. As a result, no pressure losses occur in either of the two stop positions, the piston returns automatically to the first stop position in the unloaded condition and the damping performance during the damping process is very uniform and continuous. <IMAGE>

Title: Activated rnase l as a marker for virus infections
IPC: C07H21/00
Filed: 1988-03-02
Abstract: A first line of cellular defense against many viruses, including those causing AIDS, is activation of an intracellular biochemical system termed the 2'-5' oligoadenylate/RNase L pathway. It is well known that this pathway malfunctions in individuals with progressive AIDs-related immune dysfunction, but the mechanism of malfunction remained obscure. An inhibitor substance, released in HIV infected cells or a virus directed inhibitor of biochemical intermediates in the 2'-5'A/RNase L pathway, Which by apparently physically attaching to the terminal product (RNase L) in the biochemical pathway, causes the entire system to malfunction which thus allows HIV to multiply uncontrollably has now been identified. The relative intracellular level of this newly-isolated inhibitor has prognostic significance with respect to the development of full-blown AIDS and eventual death.

each driven tine; utilises a phase quadrature component of the 
detection signal so as to drive the driven tines towards a 
condition of torsional balance.

Title: Saw-orthodontic tooth treatment device
IPC: A61C7/12
Filed: 1989-11-24
Abstract: A device (1) for jaw-orthodontic tooth treatment. It is especially suitable for displacement (distalisation) of molars (M) in the jaw and has contact points (3) engaging on the side teeth to be treated and also an abutment splint (6) engaging on teeth. In this case the contact points (3) and the abutment or abutments (6) for displacement of the side teeth are tensioned against one another and/or pressed apart by means of a clamping device (5) or similar spacing device. The invention is characterised in that the abutment is designed as an abutment splint (6) surrounding an area of the row of teeth of the jaw to be treated at least partially in a form-adapted fashion. Such a device (1) can be accommodated almost completely in the mouth of the patient, and the distalisation force required for treatment can be generated exclusively intraorally. Also, sizable parts of the device (1) can be removed from the mouth by the patient himself and inserted there again, so that cleaning of the teeth and of the device is simple.

Patent EP-0456354-A3 (EP)
Title: Integrated circuit buffer with improved drive capability
IPC: H03K17/16
Filed: 1991-04-16
Abstract: An output buffer provides for additional current sinking or sourcing 
capability by switching in an additional transistor (M6) when the output voltage 
(V OUT ) passes a given level. This allows the output buffer to supply DC current to a 
load without requiring an excessively large AC drive capability, which could 
undesirably increase switching noise. In a typical embodiment, an inverter (104) 
senses when the buffer output voltage reaches its switching threshold (approximately 
V DD /2), and turns on the additional transistor (M6) after a given delay. For example, 
a CMOS output buffer driving a TTL load may obtain additional current sinking 
capability by this technique. On-chip buffers (e.g., bus drivers and clock drivers) 
can also benefit from this technique.

Title: Electrical diaphragm valve.
Inventor: ZAKAI AVI
IPC: F16K31/53
Filed: 1994-03-28
Abstract: An electrically-operated fluid valve comprising at least one valve seating (11), a flexible diaphragm (13) covering the valve seating and being uniformly subjected on a lower surface thereof to a fluid pressure, and a closure member (28) pivotably mounted above the flexible diaphragm and rotatable about a pivot axis (29) thereof between first and second positions. An electrical motor (36, 81) is provided for rotating the closure member in a first direction whereby a first end of the closure member (14) depresses the diaphragm on to the valve seating, thereby reducing the pressure on one surface of the diaphragm within an area of the valve seating only, an opposite surface of the diaphragm and an opposite end of the closure member (18) still being subjected to said fluid pressure. The electrical motor rotates in the opposite direction for lifting the diaphragm from the valve seating. Preferably, the electrical motor (81) is controlled by a switching circuit (85) including first and second d.c. supply rails (111, 112) connected across a storage element (125) connected in series with the motor (81). A normally closed switching element (115) is responsive to a voltage across the supply rails rails for opening and allowing current to flow through the motor so as to urge the closure member into the second position whilst substantially fully charging the storage element (125), whereupon decoupling the voltage from across the supply rails causes the switching element (115) to close thereby providing a discharge path through the motor for the storage element which discharges thereby urging the closure member (28) into the first position. <IMAGE>
