Abstract: LOGARITHMIC DIGITALLY VARIABLE    GAIN CONTROLLED AMPLIFIER            Abstract An integratable amplifier circuit is provided including a current generator section, a digital control section and a variable gain amplifier section. The integratable amplifier circuit is compatible with the bipolar process and can be included on an integrated circuit, such as one performing receiver and audio functions.  The current generator section produces a biasing current which is applied to a digital control section which divides the biasing current according to a binary input signal to produce a control current equal to a predetermined fraction of the biasing current, corresponding to a predetermined logarithmic attenuation. The control current is applied to a control input of the variable gain amplifier section to vary the gain thereof in logarithmic steps.

Abstract: COMPRESSION IGNITION ENGINE FUMIGATION SYSTEM     ABSTRACT           A system for mixing fumigation fuel with the intake air in a compression ignition engine includes a variable area venturi in an engine intake air duct to draw controlled amounts of a pre-mixed fumigation fuel/air mixture into the main air stream in proportion to the amount of suction created downstream of the variable area venturi by the engine air flow.  The variable area venturi creates a pressure depression proportional to the engine air flow motivating the fumigation fuel/air mixture to flow into the engine along with the main air stream at a rate related to the engine load and speed.  The variable area venturi includes a housing having a downstream branch connected to a conventional demand-type mixer which is supplied with the fumigation fuel via a demand-type regulator, and air through a filter from the atmosphere. The variable area venturi is formed by a spring-loaded, normally closed flapper valve which variably opens in response to air drawn through the housing  by the en-gine.  The variable area venturi thus created provides a proportional control of the fumigation fuel introduced into the main air stream over a wide range of engine operating conditions with relatively small pressure drops.

Abstract: SEMI ENCLOSED ALTERNATOR An inexpensive semi enclosed alternator (10) provides high power prolonged operation in environments having particle contamination in the ambient atmosphere. An alternator housing (11) has front and rear housing portions (12, 13), and a drive shaft (14) carrying a rotor assembly (,18) is within the housing. A drive shaft extension (16) from the housing (11) has a fan assembly (32) attached thereto. The rear housing portion (13) comprises cylindrical sidewalls (26) joined to a closed end portion (27) and forms an air sealed cavity (27a) except for an open end (28) facing the front housing portion (12). The front housing portion comprises cylindrical sidewalls (29), having through-openings (33) therein, which terminate in a first end opening (31), facing rear housing open end (28), and a substantially open second end opening (30) facing the fan assembly and the ambient atmosphere. Preferably rotor and stator assemblies (18, 19), and rectifying diodes (20), are positioned within the housing (11) substantially between the through-openings (33) and the closed end portion (27) of the rear housing. During normal drive shaft rotation, the fan assembly draws cooling ambient air into the housing (11) through the through-openings (33), and this air is then drawn out of the housing through the second end opening (30) of the front housing portion. This causes cooling air turbulence within the housing while not directly exposing most internal alternator components to particle contamination in the ambient atmosphere. A voltage regulator (22) is provided in a sealed protective cavity (41) external to the internal cavity (27a). A heatsink (44) which is part of the voltage regulator is utilized to form part of the walls (40, 42) that create the protective cavity.

Abstract: ABSTRACT OF THE DISCLOSURE Programmed overcurrent protection control appar-atus with selectable time-overcurrent operation to govern the interruption of current through at least one power line associated with either a ground phase or a power phase of a power system network is disclosed.  A programmed processor is  included  to  derive  an  overcurrent  time-to-trip  in accordance with sampled measurement current values of the power line and selected derivation constants stored in a memory look-up table.  The derivation constants are sel-ected from the look-up table based on derivation parameters which may be set and read by the programmed processor from time  to  time.   The  programmed  processor  utilizes  the selected derivation constants to derive the time-to-trip over a number of predetermined time intervals during which the overcurrent condition persists.  An alternate overcur-rent time-to-trip relationship utilizing different deriva-tion parameters  selected from the  look-up table may be utilized for the conditions in which overcurrent exists in an initial predetermined range.  In some situations, both of the derivation relationships may be used concurrently to derive the overcurrent time-to-trip.

Abstract: ABSTRACT           The vane of the impeller in a high-speed or mixed-flow centrifugal pump for the conveying of liquids which contain high or low concentrations of strands or strips of vegetable, plastic or other material has a convex inlet edge whose curvature increases gradually in a direction radially outwardly from the axis of rotation at such a rate that the resultant force of centrifugal force and resistance encountered by a strip or strand at a particular point of the inlet edge is invariably tangential to the respective point of the inlet edge.  This ensures that the strips or strands do not overlie and circulate with the inlet edge but are entrained by the resultant force to become separated from the vane.  The inlet angle of the vane in a region which is remote from the axis of rotation is disposed at the suction side of the vane; this also contributes to prevention of accumulation of strips or strands along the inlet edge.

Abstract: A conveying device directs printed products past a stationarily arranged ink jet printer. A control system initiates a printing operation by the printer each time a printed product passes through the effective printing zone or region of the printer. The conveying device comprises an individual conveyor equipped with gripper units arranged in spaced relationship from each other, each of which is structured to take-up or engage one printed product. The control system includes a pulse generator driven by the individual conveyor and transmits a control pulse for each one of the gripper units. The control pulse is suppressed by a monitor responsive to empty gripper units. Since the printed products are conveyed by the gripper units, their reference position relative to the conveying device is defined over the entire product conveying path. The control signal initiating the printing operation thus can be utilized for initiating other operations after passing through a delay element.
