Title: Self-closing valve and valve assembly
Inventor: HART THOMAS G
IPC: F16K21/06
Filed: 1989-02-27
Granted: 1992-11-06
Abstract: A self-closing valve, e.g. for use in a faucet, allows the discharge of water for a predetermined time for each cycle of operation. The valve (12) has a timing means which determines the elapsed time for its operational cycle by filling a chamber (54) of predetermined size with air via an orifice (75). The valve comprises a valve body including a valve housing (17,23) and having an inlet, an outlet and a water passageway (19) between the inlet and outlet; a water valve in the valve body, comprising a stationary valve seat (30) and a displaceable valve member (28) in the water passageway, and a valve actuating member (25) for moving the displaceable valve member (28) so as to open the valve. The valve assembly further includes an air metering means including: a piston (43) reciprocably mounted in the valve housing (17,23) so as to define an air chamber (54), and operably connected with the actuating member (25) in such a way that when the valve is opened the piston moves in the direction of compression; a restoring means (46) for urging the piston in the direction of expansion; a one-way valve means (62,63) to allow air to escape from the air chamber (54); and an orifice (75) for allowing a controlled flow of air back into chamber (54) as the piston (43) returns under the influence of the restoring means (46), thereby to close the valve.

Title: Aircraft tractor without a tow bar
Inventor: FRANKEN WILHELM
IPC: B60P3/11
Filed: 1990-04-28
Granted: 1996-05-06
Abstract: The subject matter of the invention is an aircraft tractor without a tow bar. 
<??>The prior art is a tractor in accordance with DE 3,616,807 A1, in which the stationary parts of the two parallel telescopic rods for displacing two tension arms in order to draw the aircraft nose undercarriage into a recess of the running gear rear part are rigidly attached to the running gear front part, hydraulic cylinders for longitudinal displacement of the telescopic rods or for moving a nosewheel holder being attached to the fixed rod parts or to the front part. 
<??>The disadvantage of these attachments is the changing point of application at which the tension arm grips the nosewheel from behind - depending on the diameter thereof. 
<??>The object of the invention is to keep constant for different nosewheel diameters the degree of reliability with which the nose undercarriage standing on a lifting blade which is mounted on the front part and projects into the recess is held down on the surface of said plates which support said undercarriage. 
<??>This object is achieved by means of the hinging (40, 44, 46) of each telescopic rod (30) to the front part (10.1), directly at the front and by means of a coupling hydraulic cylinder (42) at the rear, and of the fixed arrangement not only of the hydraulic cylinder (-) for length adjustment, but also of the hydraulic cylinder (36) for moving the holder (34) on the fixed part (30.1) of the associated telescopic rod (30). 
<??>The advantage of this solution is the height adjustability of the two (rear) tension arms and - at the same time - of the (front) holder, which can be applied at the desired two points of the wheel circumference independently of the nosewheel diameter. (The distance between the arms and holder is variable.)

Abstract: The circuit comprises a rectifier (1) for rectifying various signals transmitted from the exchanging office to output, a photo coupler (PC) for generating a photo signal by a control signal of a micom to convert the photo signal into an electric signal, a switch (2) for switching according to the value of the photo coupler (PC), a loop switch (3) for switching signal of the rectifier (1), a ring generator (4) for detecting ring signal from the loop switch (3) to generate ring signal, and a call circuit (5) for controlling voice signal to output to a speaker (SP).

Title: Cell-free synthesis and isolation of novel genes and polypeptides
Inventor: GLENN KAWASAKI

Abstract: A method for the cell-free synthesis and isolation of novel genes and polypeptides is provided. Within one embodiment, an expression unit is constructed onto which semi-random nucleotide sequences are attached. The semi-random nucleotide sequences are first transcribed to produce RNA, and then translated under conditions such that polysomes are produced. Polysomes which bind to a substance of interest are then isolated and disrupted; and the released mRNA is recovered. The mRNA is used to construct cDNA which is expressed to produce novel polypeptides.
