Title: High-frequency dual-band feeder and antenna incorporating the same
Inventor: SALVAT FRANCOIS
IPC: H01Q5/00
Filed: 1982-01-12
Granted: 1987-05-21
Abstract: A two-band multimode microwave source for an antenna of a low-elevation-tracking radar comprises a higher-frequency section nested in a lower-frequency section, the two sections having E-planes perpendicular to each other. The lower-frequency section includes two outer pairs of waveguides separated by a block which convergingly projects beyond their output ends and is bisected by the E-plane of that section. The higher-frequency section includes two inner pairs of waveguides disposed within that block and separated by an obstruction lying in the last-mentioned E-plane. The higher-frequency wave emitted by the inner waveguides is made planar by a lens disposed at n output aperture of the structure which is transparent to the lower-frequency wave. In a Cassegrain-type radar antenna the lower-frequency wave emitted by the source is returned by a semitransparent intermediate reflector toward a main reflector provided with a grid which rotates its plane of polarization to let it pass out through the intermediate reflector along with the higher-frequency wave which, passing unattenuated through the intermediate reflector, is returned by a solid outlying reflector to the main reflector.

Title: Velocity-position servo withh improved gain control
Inventor: WONG HARVEY C
IPC: B41J1/30
Filed: 1984-08-17
Granted: 1988-12-01
Abstract: In a rotary printer control system, a dual mode servo for controlling the velocity and position of a rotary print wheel and a print wheel carriage is normally operated at a relatively high gain value. When the servo is switched from the velocity mode to the position mode, the length of time the servo remains in the position mode is monitored and, if this exceeds a predetermined maximum time period, the gain of the servo loop is switched to a relatively low value in order to reduce oscillations of the print wheel or carriage about the HOME position. The gain reduction is accomplished by inserting a supplemental R-C network in parallel with the high gain R-C network, and the range of ratios of the relatively high gain to the relatively low gain values is from about 10 to about 30.

IPC: B60R19/02
Filed: 1986-01-16
Granted: 1989-06-29
Abstract: The collision protection device comprises a collision protector held in a rest position by spring force. Upon collision against an obstacle, the collision protector is displaced against the spring force and thus cooperates with a de-energizing device. This collision protector is mounted on the vehicle chassis by two swing arms arranged symmetrically non-parallel or in angled relationship to the longitudinal axis of the vehicle. This is to permit the de-energizing device to function effectively, irrespective of the place of impact of the obstacle against the collision protector and irrespective of any deformation of the collision protector. Each swing arm is pivotably mounted on the collision protector and on a sliding link member. Each sliding link member is acted upon by the spring force and is displaceably positioned on a cross-shaft mounted on the vehicle chassis perpendicular to the longitudinal axis of the vehicle. Each sliding link member cooperates with the de-energizing device by means of a switching cam or ramp surface when displaced against the spring force. Two flexible retaining elements which may comprise cables or bands connect the collision protector with the vehicle chassis. These cables or bands are arranged at or adjacent the sides of the vehicle and symmetrically to the longitudinal axis of such vehicle.

Abstract: Heat sealing of wrapper laminates (31, 32) made of foam (102) supported by a porous substrate sheet is improved by coating on the foam-engaging face of the substrate a barrier layer such as polyvinylalcohol to keep the foam (102) when melted from bleeding through the substrate. The support for the foam can alternatively be non-porous film such as polyethylene terephthalate. In a cold sealing embodiment the foam face of supported foam wrappers has a cohesive-nonadhesive layer which can contain improved volatile corrosion inhibitor and/or antistat compositions that do not shorten its shelf life below about six months. One such composition is a mixture of dicyclohexylamine with 2-amino-2-lower-alkyl-propadiol-1,3. Protective colloid such as polyvinylpyrrolidone is preferably also added to improve the compatability of the volatile corrosion inhibiting composition with the rubber latex that provides the cohesive-nonadhesive characteristics. Heat sealing of wrapper can be effected with the help of hot melting shoes (39 and 41).

Abstract: In a free-running pressure wave supercharger driven by the gas forces, nozzles (27) are provided in the gas casing (6) and possibly also in the air casing (5), which nozzles are connected-via a drive line (26)-with a position in the air casing (5), preferably with the high-pressure air port (2), at which position a surplus pressure relative to the nozzle entry occurs during the run-up phase of the pressure wave supercharger. A control device 15 actuates a supercharge air flat (14) in the port (2) and a valve device (23+25) in the drive line (26) in the opposite sense, i.e. if the supercharge air flap (14) holds the port (2) closed, the valve device (23+25) frees the flow through the drive line (26) to the nozzle (27) and vice versa. The diaphragm capsule (17) of the control device (15) is subjected, on one side, to the pressure in a compression pocket (11) via a control pressure line (19) and, on the other side, to the pressure before the supercharge air flap (14) in the port (2). During the run-up phase, the pressure in the compression pocket (11) exceeds the pressure in front of the supercharge air flap (14) and the nozzle (27) receives drive air. As soon as the pressure in front of the supercharge air flap (14) exceeds the pressure in the compression pocket (11), the supercharge air flap (14) opens and simultaneously closes the valve device (23+25). The nozzle (27) is switched off and the further drive is then mainly provided by the high-pressure exhaust-gas jet from the port (3) entering obliquely to the direction of the rotor peripheral velocity.
