Patent EP-0234806-B1 (EP)
IPC: H03F3/45
Filed: 1987-02-11
Granted: 1990-10-10
Abstract: A high speed low power linear two micron CMOS full differential operational amplifier has a pair of output cascode stages (44, 45) each providing a respective differential output with rejected common mode signals. The amplifier comprises an input differential amplifier stage (72) driving a pair feedback current mirror loads (18, 20) each cross connected to the pair of cascode output stages providing the differential outputs. Current domain operation provided by current mirror arrangements (34,35) enables fast operation of the full differential amplifier. Each output cascode stage comprises four stacked transistors including two signal transistors and two dynamically biased pass transistors. The feedback current mirror loads (18,20) and the cascode output stages (44, 45) provide the amplifier with single gain stage respecting each differential output thereby reducing the need for large compensation capacitors while improving the dynamic range of the two differential outputs. The gain of amplifier is ninety decibels with a frequency bandwidth of fifth megahertz and with low power dissipation at two milliwatts. The amplifier also comprises two feedback differential stages (62, 64) receiving a single combined common mode signal (60) formed the two differential outputs. Each feedback differential stages then drives a respective pair feedback current mirror loads (78,80,82,84) which provide negative feedback signals to the output cascode stages (44, 45) whereby common mode signals are rejected at the differential outputs.

Title: Vehicle locating system
Inventor: SAGEY WILLIAM B
IPC: G01S5/02
Filed: 1987-07-29
Granted: 1993-11-18
Abstract: A vehicle locating system (VLS) comprises a large number, for example, several million, vehicle-mounted transmitters (30, 32, 34) and several benchmark transmitters (40, 42, 44); first, second and third signal relay stations (46, 48, 50) and a central processing station (22) at which the transmitter locations are determined, the central station being connected by conventional links to subscriber stations (60, 62). One hundred microsecond-long RF signals are transmitted by each transmitter in a non-synchronized, mutually random manner. Each signal comprises a 20 microsecond synchronization symbol followed by six, four bit transmitter identification symbols, each of ten microseconds length. Following the identification symbols are 10 microsecond message and processing symbols. The control station includes correlation means for correlating the synchronization symbols on each relayed signal against stored data to identify the beginnings of the signals. Identification symbols of each signal are then decoded by correlation means to establish transmitter identification, a combination of 166 possible identifications being provided. Signals arriving in the central station are time-tagged upon arrival and the time differences of arrival (TDOA) are used to compute transmitter location. Benchmark tranmsmitter computed locations are used to calibrate the VLS. Means may be provided on the vehicle transmitters to enable the rate of transmissions to be varied, to thereby enable encoding preselected messages relating, for example, to vehicle motion, vehicle crashes and vehicle intrusion/theft, responsive to associated sensors. Alternatively, or in addition, specific, prestored messages may be encoded into the transmitted signals manually or automatically in response to sensor input.

Abstract: A paper dispenser is furnished with one or more turnable or tiltable cutting or tearing off device, equipped with serrated or jagged edges. When inactive, the cutting edge is held by a spring or by force of gravity in a safe or innocuous position. As a drawing force is applied to the paper web coming out of the dispenser, the cutting or tearing off device is turned or tilted so that the serrations of the cutting edge come into contact with the paper web. When a portion of the web is torn off, the jagged edge returns to its shielded position. The cutting or tearing off device can be directly actuated by the paper web, or via an intermediate element.

Abstract: A method fo the preparation of a low-fat butter of margarine product for use as a table spread or for other uses, including cooking, baking, etc. . The product is prepared by plasticizing a composition containing from about 15% to about 50% lipid, preferably butter fat; an amount of protein, preferably dairy protein, sufficient to emulsify the lipid but insufficient to stabilize the lipid against plasticization; and from about 40% to about 60% moisture. Salt, butter coloring and butter flavoring are preferably also included. The plasticization is achieved by subjecting the composition to the high speed cutting action of a sharp bladed food comminuter for a period of time sufficient to plasticize the composition. The product is a smooth plastic spreadable butter substitute containing nutritious protein, which is low in fat and does not require the need for emulsifiers and stabilizers. The product is spreadable immediately after removal from refrigeration, as well as at normal room temperatures.

Filed: 1989-11-08
Granted: 1992-09-23
Abstract: The present invention involves a container (1) and cap which is generally childproof and may be rendered non-childproof permanently. The invention involves a container (1) having a cylindrical neck (3) at the top and threads (5) molded about the exterior of the neck as well as an inner cap (7) and outer cap (21). The inner cap (7) has a top (9) and cylindrical side wall (11) with threads (13) molded on the inside of the side wall (11) so as to mate with the threads (5) of the container (1). The top (9) or side of the inner cap (7) has ratchet type segments (15) on its outside and the outer cap (21) has ratchet type segments (27, 29) on the inside of its top (23) or side (25). The outer cap (21) has a cylindrical side wall (25) and is usually freely rotatable about the inner cap (7) so as to be childproof. When in the childproof configuration as described, downward pressure is required by the user so as to engage the two ratchet type segments (15, 27, 29) and thereby engage the two caps (7, 21) to permit opening. Further, the outer cap (21) has an opening (37) in its side wall (25) at a level near the bottom of the side wall (11) of the inner cap (7) and also has integrally attached thereto a flexible connector (31) and stop (33). The flexible connector (31) and stop (33) are located so as to permit insertion of the stop (33) into the opening (37) so as to extend beyond the opening (37) and push up the inner cap (7) so as to permanently lock it into a position wherein the inner cap and outer cap ratchet type segments (15, 27, 29) are permanently engaged. This renders the cap permanently non-childproof.

Abstract: A method for operating a continuous wet oxidation system for destroying cyanide in caustic cyanide and metal wastes which scale upon heating comprises introducing raw waste into the wet oxidation reactor (14) without heating while a mixture of heated dilution water and oxygen containing gas is introduced into the reactor by a separate inlet (12). The reactor (14) is fitted with a pair of valved effluent lines (16,17) and corresponding valved lines (44, 50) for introducing dilute mineral acid into each effluent line at system pressure. Oxidized effluent and offgases exit through a first effluent line (16) while dilute mineral acid flows through the second effluent line (17) into the reactor to prevent scale buildup. Periodically the flows are switched such that oxidized effluent and offgases exit through the second effluent line (17) and dilute mineral acid flows through the first effluent line (16) into the reactor to remove scale. The oxidized effluent and offgases are then cooled and separated.
