Abstract: A motion sensitive theft detector system for portable articles featuring two way communication between the theft detector unit installed in or affixed to the portable article and the control unit carried by the owner. The theft detector communicates alerts to the control unit allowing the user to screen for false alarms and to trigger an alarm at the portable article when warranted. A timing based alert suppression algorithm allows the system to be carried in its armed state without creating frequently repeated alerts at the control unit. A second alarm function selected by the mode switch sounds an alarm automatically in response to motion according to an adaptive alarm sequence. The adaptive alarm varies the alarm in response to frequency and duration of motion so that isolated movement triggers a warning but persistent motion triggers a full scale alarm.

Abstract: This invention relates to a process for producing zeolite-bound high silica zeolites and the use of the zeolite-bound high silica zeolite produced by the process for hydrocarbon conversion. The process is carried out by forming an extrudable paste comprising a mixture of high silica zeolite in the hydrogen form, water, silica, and optionally an extrusion aid, extruding the extrudable paste to form silica-bound high silica zeolite extrudates, and then converting the silica of the binder to a zeolite binder. The zeolite-bound high silica zeolite produced by the process comprises high silica zeolite crystals that are bound together by zeolite binder crystals. The zeolite-bound high silica zeolite finds particular application in hydrocarbon conversion processes, e.g., catalytic cracking, alkylation, disproportionation of toluene, isomerization, and transalkylation reactions.

Abstract: A detector receiver circuit (2) for use as a wake-up detector for detecting an amplitude modulated carrier signal is described. The circuit (2) comprises: an antenna (4) for receiving the modulated carrier signal; a transistor (10), such as an FET, is connected to the antenna (4) and configured to operate as a detector of modulation of the carrier frequency. The circuit further comprises a resonator circuit (12-16) which is also connected to the transistor and configured such that the transistor (10) can simultaneously oscillate at substantially the modulation frequency; an oscillator quenching means (20) for periodically quenching oscillation of the transistor (10) and means (26, 28, 30) for sensing the characteristics of the build-up of oscillation to indicate the presence of a modulated carrier signal. How quickly the magnitude of oscillation of the transistor (10) builds up is dependent on whether the antenna is receiving a carrier signal which is modulated at the frequency of self-oscillation of the transistor and this is utilized to detect for the presence of a valid wake-up signal.

Filed: 2013-09-11
Abstract: The present invention relates to a gate hanging assembly comprising at least one gate attachment means and a support member having a receiver for the gate attachment means, wherein the gate attachment means has a locking means and a gate-holding means and wherein the gate attachment means is reversibly moveable from a first position to a second position, wherein in the first position the gate attachment means slides into and/or through the receiver and in the second position the gate attachment means is in a locked position in which the locking means engages with the support member to lock the attachment means thereto and the gate-holding means engages with and locks the gate to the support member so that the gate is pivotable about the support member. In particular the invention provides a gatepost comprising of a lightweight gatepost with a hollow core and mortise openings. The mortise openings will accommodate the steel anchor eyes which will in turn accommodate the gate. The anchor eyes will be inserted into the mortise’s and turned through 90 degrees so they are secured and will hold the gate in place. The advantage of the invention is that a lightweight gatepost can be erected single handily and the anchor fillings allow the speedy hanging of a gate and when the need arises, the gate can be speedily removed, for instance, when corralling livestock. <Figure 1>

Granted: 1996-09-23
Abstract: It consists of a cyclone filtering unit 1, which can be placed on the motor protection air filter, in which the suspended powder is removed from the air which, arriving at the bottom in a suitable ring portion 2, is aspirated into a conduit 3 by a suction expeller 4, applied to the muffler of the vehicle, and continuously expelled to the outside with the flow of exhaust gases. Air from the surroundings taken in by the motor through a cylindrical grill 5, preventing entrance of light suspended objects such as straw, twigs, etc., enters the filtering unit 1, converging in rotary movement on the chamber 6 through a circumferential vortex system of entrances 7 defined by cylindrical sector panels 8 arranged in receding series inclined towards the outside, thus forming a system of curved walls of various inclination, against which the fast moving air flow breaks. Thus, when the dust arrives at the wall, it descends into the ring portion 2 underneath, while the purified air goes to the motor via the central conduit 9 at the bottom and via the normal air protection filter. <IMAGE>

Abstract: The microcapsule magnetic display sheet is sequentially provided thereon with a transparent front sheet, a microcapsule layer coated on the transparent front sheet and then a ultraviolet ray curable resin layer. The ultraviolet ray curable resin layer is formed by painting liquid ultraviolet raycurable resin on the microcapsule layer first and then hardeningit by irradiating it with UV rays. As the liquid ultraviolet ray curable resin can fill fine gaps of the microcapsules, no hollows left between the microcapsules and the UV resin layer. As the UV resin filled in gaps shares wording pressure, the microcapsules are fully protected and hardly be destroyed. After painting the liquid UV ray curable resin on the microcapsule layer and before it IS hardened, a separable film is covered on it. While a film is covered on it, the sheet is hard and if the film is separated, the sheet is soft. So the stiffness of the magnetic display sheet can be regulated by covering or not covering a film. <IMAGE>
