Title: Pawl and ratchet assembly
IPC: A47C3/027
Filed: 1993-01-26
Abstract: An improved latching mechanism for a rocking chair having an extensible leg rest assembly is disclosed. The latching mechanism is operable to releasably lock the chair frame in a rearwardly tilted position upon extension of the leg rest assembly while permitting unrestricted rocking action when the leg rest assembly is protracted. The improved latching mechanism is a pawl and ratchet latching mechanism having a spring-biased pawl member operable to lockingly engage a toothed ratchet sector for retaining the chair frame in its rearwardly tilted position. A unique actuation arrangement is disclosed having a release member that functions to pull the spring-biased pawl member to a released position. The actuation arrangement is also operable to prevent the release member from exerting any compressive biasing loading on the pawl member when the pawl member is in locked engagement with the ratchet teeth.

Title: Apparatus and methods for implementing protocols
Inventor: HOLZMANN GERARD J
IPC: H04L29/08
Filed: 1993-01-29
Abstract: Apparatus and methods for communicating using protocols. The apparatus and methods employ protocol descriptions written in a device-independent protocol description language. A protocol is executed by employing a protocol description language interpreter to interpret the protocol description. Communication using any protocol for which there is a protocol description may be done by means of a general protocol. The general protocol includes a first general protocol message which includes a protocol description for a specific protocol. The protocol apparatus which receives the first protocol message employs a protocol description language interpreter to interpret the included protocol description and thereby to execute the specific protocol. The protocol apparatus may also be made to adapt to its environment by encaching protocol descriptions which were received in an earlier first general protocol message and interpreting an encached protocol description in response to a second general protocol message which includes a protocol identifier specifying the encached protocol description.

Title: Non-flushing toilet system
Inventor: YEUNG SHU-KI
IPC: E03D11/10
Filed: 1994-03-01
Abstract: Basically most water closet toilets in exist today are flushing-type that either need a water tank or special means such as water pump to create a fairly high-pressure for cleaning and discharge of waste by means of siphon action.  This invention of non-flushing toilet employs a totally different design principle, which does not need a high water pressure, and no need for siphon action within the toilet.  Consequently, no water tank is needed which effects save in space, and, with more efficient use of water, saving of water is also effected.  Further, as no siphon action is needed, operation noise is much reduced, resulting in a quieter toilet.  Even further, as no high pressure is required, design of Portable Toilet is also made posible.  Options of new and special features to be used in existing and future toilets, including present invention are also disclosed in this patent application.

Du fait que la croissance de dendrites de lithium ou de zinc au moment de la charge peut être empêchée, un court-circuit entre l'électrode négative et l'électrode positive peut être empêché. Par conséquent, la durée de vie de cycle de charge/décharge peut être considérablement allongée. Par conséquent, une batterie secondaire au lithium, une batterie secondaire nickel-zinc, une batterie secondaire zinc-air, une batterie secondaire brome-zinc et une batterie secondaire à oxyde d'argent-zinc ayant une longue durée de vie peuvent être fabriquées.

Title: Reversible analog to digital converter (adc-dac) with analog and digital signal processing and encoding functions
Inventor: DISTINTI ROBERT J
IPC: H03M1/38
Filed: 1992-06-09
Abstract: A Synchronous Analog to Digital (SYMAD) Convertor cell (12), and circuits formed therefrom, for converting an analog signal into a discrete binary code. An analog signal is processed by sample and hold circuitry and then compared to a reference voltage by a comparator (75). The comparator output is the converted digital output. The output is coupled back to the control input of an analog switch (81) which selects either the reference voltage or a predetermined potential, typically zero volts, to couple to an inverting input of an operational amplifier (76). The analog signal input is also coupled to the non-inverting input of the operational amplifier. The operational amplifier is configured as a differential amplifier with a gain of two. If the digital output of the comparator is a logic 1, then the operational amplifier output is two times the difference between the analog signal and the reference voltage. If the digital output of the comparator is a logic 0, then the output of the operational amplifier is two times the analog signal. As many SYMAD cells as necessary may be provided to obtain a desired resolution. Also disclosed are cyclic, chopper stabilized, zeroing A/D converters, switched resistor converter cells, logarithmic converters, including an A/D converter that provides a floating point output, an edge triggered sample and hold circuit, and an array of configurable analog converter cells for implementing a desired analog signal processing function.

Patent CA-2114528-A1 (CA)
Inventor: BROWN WILLIAM M
IPC: G01S13/90
Filed: 1992-09-03
Abstract: Synthetic aperture radar data is used in conjunction with altimeter data (a) to produce a terrain map corrected for platform roll angle. The technique uses two synthetic radar antennas (21, 22) and a ranging altimeter (23) placed on an aircraft. The aircraft is moved in a set of substantially parallel flight paths where each flight is directly over the strip of terrain viewed by the synthetic aperture radar of an adjacent flight. During each flight the at least one antenna repeatedly transmits radar signals whose return echoes are received by both the first and second antennas.  Conventional synthetic aperture radar processing yields a terrain map uncorrected for roll angle.  The uncorrected terrain map data from one flight are compared with the altimeter data taken during an adjacent flight.  This roll angle measure is then used to correct the height and ground range of nearby points in the uncorrected terrain map.

Abstract: PROCESS FOR THE DESULFURIZATION OF  SULFUR DIOXIDE-CONTAINING GASES                                ABSTRACT   The process of invention provides a simplified conversion of sulfur dioxide gas into hydrogen sulfide gas. First, sulfur dioxide gas is absorbed into an aqueous sulfide solution to form sulfite and bisulfide ions. Second, additional sulfur dioxide gas is absorbed into the aqueous solution to form hydrogen sulfide. Third, another portion of the sulfur dioxide is absorbed and reacts in the aqueous solution to form bisulfite. Most advantageously, the bisulfite is decomposed into sulfur dioxide and sulfite. The sulfite is then reduced to sulfide and returned for use in the absorption process. The hydrogen sulfide may then be reacted with SO2 via the Claus reaction to form elemental sulfur.
