Abstract: The present invention relates to an automatic gain control circuit (AGC) in a receiver for a digital radio telephone. Most of the total gain control of the received signal is accomplished in the base band frequency sections, in the I and Q branches whereof the signal amplification is controlled step by step, and only a minor part of the total gain control is performed in the RF stage. High amplification steps are formed by means of amplifiers (9a, 10a, 11a, 12a; 9b, 10b, 11b, 12b), of which the desired amplifier is activated by means of a digitally controlled (A, B) multiplexer (13a, 13b), and low amplification steps are formed by means of a resistance attenuator (14a, 14b), in which a signal of desired level is selected by means of a digitally controlled (C, D, E) multiplexer (15a, 15b). In addition, the RF amplifier (2) has two amplification levels, of which the desired amplification is selected by means of a digital control (F). By means of different digital control combinations (A, B, C, D, E, F) the entire gain control range required of the receiver can be covered.

The cords of each of the two radially inner layers are substantially parallel to each other and inclined with respect to the direction of travel of the tire but the cords of one of the two layers cross those of the other layer. The cords of the third layer are substantially parallel to each other and to the direction of travel of the tire. The third layer has a central strip astride the center line of the tire and a lateral strip on each side of the center strip which is more resistant to tension and compression stresses than the center strip.

Abstract: In an inverter controlled with a firing unit connected to switches and defining an operating frequency, a resonant frequency of a series oscillating circuit of the inverter connected to one of the switches is placed below this operating frequency. Given this operating situation, a short of the d.c. voltage source is impossible. Given, for example, unfavorable component tolerances, however, the operating frequency can be moved close to the resonant frequency and cause impermissibly high voltages at the components. Such a voltage rise is limited according to the invention by means of a voltage-dependent resistor. It preferably lies in series with a capacitor and takes care of a voltage-dependent shift of the resonant frequency.

Abstract: A container for liquids comprises a tube at the upper end of which there is a lid consisting of thermoplastics synthetic material without any carrier material and which is injection molded along the top edge of the tube, forming a pouring means with a closure flap. The closure flap is captively articulated on the lid by means of an articulating axis, on the side opposite the tip of the pouring aperture, being adapted to be engaged on the lid in the open condition via an engaging means. In order that the closure flap can be kept open and can nevertheless be pressed down again into as far as possible a clearly defined position in order to reclose the container, the handle is connected via a curved articulating member to the middle portion of the lid. The curved articulating member is preferably provided on the surface of the lid alongside the engaging means.

Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus for executing a conditional branch instruction in a pipelined processing unit which has an instruction queue for storing an instruction stream, address generating apparatus connected to the head of the instruction queue for generating and retaining an address defined in the portion of the instruction stream presently at the head of the instruction queue, and instruction interpretation apparatus which is also connected to the head of the instruction queue for receiving and interpreting an instruction as the head of the instruction queue.  A conditional branch instruction which is presently at the head of the instruction queue is executed by first performing a dispatch operation in a first cycle which is the last cycle of execution of the instruction preceding the conditional branch instruction in the instruction queue.  The dispatch operation sets up the execution of the instruction at the head of the instruction queue.  One result of the dispatch operation is the generation of the address for the target instruction specified in the branch instruction.  Thereupon, in an immediately following second cycle, a conditional fetch operation and a test operation are performed.  The conditional fetch operation provides the address for the target instruction to the processing unit's memory.  The test operation determines whether the branch is to be taken.  If the branch is not to be taken, the target instruction is not loaded into the instruction queue, the cycle is extended, and a dispatch operation is performed in the extended cycle.  If the brach is to be taken, the target instruction is loaded into the head of the instruction queue in the second cycle.  Finally, when the branch is taken, the dispatch operation is performed in an immediately following third cycle.

Title: Liquid cryogenic freezer with improved vapor balance control
Inventor: LANG GARY D
IPC: F25D29/00
Filed: 1990-09-11
Granted: 1997-04-29
Abstract: A cryogenic freezer apparatus for food products, including a thermally insulated enclosure and conveyor means for conveying products through the enclosure.  A cryogen unit in the enclosure produces cryogen vapor near the enclosure entrance, and a blower unit is located in the enclosure adjacent the entrance thereof.  The blower unit is selectively reconfigurable in response to a blower control signal to selectively direct cryogen vapor in varying directions, drawing cryogen vapor away from a first portion of the enclosure and blowing cryogen vapor toward a second portion of the enclosure.  A photocell unit outside the enclosure, adjacent the entrance thereof, detects cryogen vapor exiting the enclosure entrance and generates at least one sensor output signal in response thereto, being indicative of the amount of cryogen vapor exiting.  A control unit is coupled to the photocell unit and to the blower unit for generating a blower control signal in response to the sensor output signal so that, with increasing vapor detected outside the entrance of the enclosure, the blower unit draws cryogen vapor away from the enclosure entrance.  Also, upon detecting a decreasing amount of cryogen vapor exiting from the entrance of the enclosure, the blower unit directs less cryogen vapor away from the enclosure entrance to assure that intrusion of the ambient environment through the enclosure entrance is prevented.

Abstract: A phenylethanol dehydrogenase capable of catalyzing the reduction of acetophenone to R(+)-phenylethanol in the presence of NADPH was isolated from Lactobacilli such as Lactobacillus kefir. The dehydrogenase is also capable of catalyzing the reduction of aromatic, alicyclic and aliphatic ketones selected from the group consisting of p-bromoacetophenone, methylcyclohexanone, acetone, methyl hexyl ketone, 4-phenyl-2-butanone, 1-phenyl-1,2-propanedione, ethyl pentyl ketone, pinacolone, propiophenone and p-chloroacetophenone. The dehydrogenase is rapidly inactivated by EDTA, but conventional inhibitors, chelators and SH-protecting reagents have only a slight effect on activity. The enzyme has a K M of 6 x 10-4 M for acetophenone. The dehydrogenase is capable of catalyzing the enzymatic reduction of carbonyl compounds to form optically active hydroxy compounds in the presence of NADPH. In such reactions, NADPH can be simultaneously regenerated in the presence of glucose 6-P and glucose-6-P dehydrogenase or isopropanol.

Title: Force balance instrument with electrostatic charge control
Inventor: STEWART ROBERT E
IPC: G01P15/13
Filed: 1991-10-03
Granted: 1999-12-07
Abstract: A force balanced instrument, such as an accelerometer, employs a pendulous mass having combined electrostatic pickoff and forcing plates on opposite sides thereof. The plates provide a constant attractive force in successive periods acting alternatively on opposing sides of the sensitive element. Force balance is achieved by controlling the duty cycle so that the difference in duration between each of the parts of a full cycle is a linear measure of acceleration. Voltage on each of the forcing plates is sensed independently immediately after each is charged with a fixed charging pulse which provides a fixed force level aver the duration of the part cycle.      The two successive voltage simples are stored, and the difference between them integrated to control the duty cycle of a pulse width modulator, which itself controls the duration of application of the alternately directed forces applied by the respective plates to the pendulous mass.
