IPC: H03H11/04
Filed: 1977-08-18
Granted: 1983-10-25
Abstract: PHN. 8499.           ABSTRACT:    Transmission arrangement for information sig-nals comprising a fixed input network, a fixed output network and at least one adjustable network coupled between the fixed input and output networks.  The adjust-able network has a transfer characteristic as a function of the frequency .omega. within a prescribed frequency band approximately equal to C exp [kf (.omega.)], where C is a con-stant and k a continuously variable parameter.  The adjust-able network comprises N channels connected in parallel between input and output and having a number n from the series of integers 1,2, ..., N, the channel having number n=1 comprises a fixed circuit coupled between input and output of the adjustable network and which has a fixed transfer characteristic.  The channels having a number n with 2?n?N comprise a fixed circuit and an adjustable circuit in cascade between input and output of the adjust-able network.  The fixed circuit for the channel having a number n with 2?n?N has a transfer characteristic approx-imately equal to [f (.omega.)] n-1/(n-1): times the fixed trans-fer characteristic for the channel having number n=1.  The adjustable circuit for the channel having a number n with 2?n?N is controlled by the continuously variable k and has a transfer kn-1 substantially independent  of the frequency .omega. whereby the transfer characteristic of the channel having number n is approximately proportional to the n-th term from the series of N terms of the development of exp [kf (.omega.)] to powers of kf (.omega.).

Abstract: ABSTRACT      A water craft, e.g. a tug, has a rudder propeller or other thrust generator rotatable about a vertical axis, for steering, and arranged under the front half of the craft.  The thrust generator is arranged under a shaft construction comprising an outer wall which is a substantially fixed component of the hull and has its upper end above the water line, and an inner wall mounted in the outer wall so that it can be raised. The inner shaft wall is supported by thrust blocks in the space between the walls.  The thrust generator is mounted on the inner shaft wall and is drivable from within the craft via a transmission passing through the shaft construction.  The rotating thrust generator occupies a space whose horizontal extent is smaller than that of the clear space which exists within  the outer shaft wall when the inner shaft wall is raised.

Abstract: LINE PROTECTOR FOR A COMMUNICATIONS CIRCUIT     Abstract of the Disclosure A line protector for a communications circuit provides overvoltage and overcurrent protection.  The over-voltage protection is effected through an arrester that provides an arc gap from the line to ground.  For over-current protection a fusible element is melted by a heat coil causing a conductive cup to move into engagement with a conductive plate that is connected to a line pin, thereby forming a direct metallic shunt to ground.  The heat coil assembly, the line pins, and the contact plates associated with the line pins are mounted on a dielectric sub-base which in turn is supported by the base of the protector.          The ends of the heat coil are welded to the contact plates and the line pins are staked to the contact plates, thereby eliminating noise-causing butt contact connections in the line circuit.

Abstract: Abstract of the Disclosure To facilitate relative movement between the internal surface of a pneumatic tire which come into contact when the tire is run in a deflated condition, the interior of the tire is coated with a lubricant which does not flow at normal tire operating temp-eratures.  The matrix of the lubricant is a polyester, polyurea or polyurethane which does not begin to flow until the tire reaches a temperature of from 65°C to 150°C.  If the lubricant were allowed to flow at operating temperature, it would adversely effect the balance and performance of the tire.  The high tire temperature indicates that the tire is flat and reduces the viscosity of (liquifies) the lubricant causing it to flow.  the lubricant then reduces rubbing friction and temperature rise which would otherwise occur by rubber-to-rubber contact.  The lubricant tire can be run flat to a service station.

Granted: 1982-05-11
Abstract: ABSTRACT           Highly effective chromatographic column packings are prepared by reacting hydroxyl groups on a silica surface with SiC14 and then reacting the chloros?lylaced surface with a polyglycol or polymeric glycol ester in 3 slurry reaction. Residual chlorosilane groups on the reacted surface are neutralized by reaction with methanol or other lower alkanol. The resulting modified silica has a bonded, essentially monomolecular organic surface film which provides thermal stability, uniform efficiency, and rapid analysis when the material is used as a column packing in gas-liquid chromatography.
