Title: Intrusion detection system
Inventor: MAKI MELVIN C
IPC: G08B13/24
Filed: 1986-11-06
Granted: 1991-02-19
Abstract: ABSTRACT         An intrusion detection system using waves guided by the conductive outer sheath of a coaxial cable.  An r.f. signal from a transmitter is supplied between the inner conductor and outer conductor or shield in conventional fashion.  Coupled wave devices are spaced along the cable; each coupled wave device transferring r.f. energy between a transmission mode within the cable and a guided mode propagated along the exterior of the conductive outer shield.          In one embodiment a second coaxial cable similarly provided with coupled wave devices is spaced from the transmitter cable and has one end connected to a receiver.  The change in r.f. coupling between the cables caused by an intruder pro-duces  variations in the r.f. energy coupled to the second cable which is detected at the receiver.  Alternative embodiments include the use of a single cable with coupled wave devices adapted for both transmission and reception.          Further alternative configurations include the use of a leaky coaxial cable, preferably buried, operating in combination with a cable provided with coupled wave devices.          In some circumstances a single elongated conductor can support the guided mode.  The guided mode can be established in the outer shield or single conductor by an external source and need not always be coupled from the cable interior.

Title: Process for producing shaped refractory products
Inventor: JAIN MUKESH K
IPC: C04B35/111
Filed: 1987-10-22
Granted: 1992-12-29
Abstract: Abstract The present invention relates to shaped refractory products, particularly in the form of hollow spheres, and to a process for their formation.  The process involves dispersing particles of silica or a metal oxide, e.g. Al2O3, in an organic polymer, shaping the dispersion into a desired shape, heating the shaped dispersion in a non-oxidizing atmosphere to carbonize the polymer, and heating the carbonized product at high temperature in a non-oxidizing atmosphere containing nitrogen so that some of the oxide is converted to the corresponding nitride and the particles of unreacted oxide sinter together.  The ratio of oxide to carbon should be high so that some but not all of the oxide is converted to the nitride and, preferably, only a relatively small amount should be converted.  The resulting refractory material is strong and can be used for a variety of uses, e.g. catalyst supports, packing materials and insulating materials.

Title: Droplet deposition apparatus
Inventor: MICHAELIS ALAN J
IPC: B41J2/045
Filed: 1988-01-08
Granted: 1991-12-10
Abstract: ABSTRACT OF THE DISCLOSURE    A pulsed droplet ink jet printer has relatively long thin ink channels extending in parallel between an ink manifold 13, and a nozzle plate 5 providing a nozzle 6 for each channel.  Side walls 11 may be formed substantially entirely of piezo-electric material so as to be displaceable transversely into a selected channel on the application of an electric field.  This transverse displacement produces an acoustic wave in the channel which results in the ejection of an ink droplet.  The side walls may deflect in shear mode to a cross-section of chevron formation.          Usefully, it is arranged that both side walls adjoining the selected channel are displaced inwardly of the channel to cooperate in droplet ejection.  Under this arrangement, the channels are assigned alternately to first and second groups of channels, only one group of channels being capable of actuation at any one instant.  The nozzles associated with the respective groups of channels may be offset so as to compensate for the time delay in actuation of channels in the first and second groups.

Filed: 1988-05-12
Granted: 1992-05-12
Abstract: ABSTRACT         A process for the preparation of a cellulose ether is described herein by reacting in a heterogenous reaction mixture an alkaline solution and an etherifying agent with a fibrous cellulose.  The total of the required stoichiometric amount of the alkaline solution and at least a portion of the etherifying agent required in producing the cellulose ether are admixed at sufficiently low temperature to suppress reaction between the alkaline solution and the etherifying agent.  The admixture is then contacted with the cellulose fibers, preferably by spraying the admixture thereupon.  Additional amounts of the etherifying agent is then added, if required, to the reaction mixture, and the heterogenous reaction mixture is agitated and reacted at an initial temperature below 40°C, sufficient to produce alkalization of the cellulose.  Thereafter the temperature is increased above 40°C to produce etherification of the cellulose and form the cellulose ether.     33,945-F

Title: Single revolution ice maker
Inventor: CHESNUT PAUL B
IPC: F25C5/08
Filed: 1988-08-02
Granted: 1991-09-24
Abstract: Abstract An  ice  making  apparatus  utilizes  a  single thermostat for energizing and de-energizing a mold heater which is utilized to free  ice bodies from a mold.   The thermostat has a narrow operating range so that the heater is de-energized substantially immediately after the ice body is free from the mold to enable harvesting of the ice bodies to be completed in a single revolution of an ejector blade.          The  short time during which the heater is  on allows  a subsequent freezing cycle to be completed faster and the single  revolution  permits  the  harvesting  cycle  to  be completed faster in order to increase ice production of the ice maker.
