Abstract: An automatic clutch controller for a vehicle that reduces the oscillatory response to clutch engagement. The automatic clutch controller receives inputs from an engine speed sensor and a transmission input speed sensor and develops a clutch engagement signal controlling a clutch actuator between from disengaged to fully engaged. The clutch engagement signal at least partially engages the friction clutch in a manner to cause the measured transmission input speed to asymptotically approach a reference speed employing an approximate inverse model of this oscillatory response. In a launch mode, corresponding to normal start of the vehicle, the reference speed is the measured engine speed. In a creep mode, corresponding to slow speed creeping of the vehicle, the reference speed is a creep speed reference based on the throttle setting and the engine speed. The two modes are selected based upon the throttle setting.

Abstract: The normal course of operating a numerically controlled machine tool includes the automatic collection of significant event data without any special interaction by the machine tool operator. These events are of two types: those embedded in the machine tool part program, which may be ordinary program steps or special event markers; and those which represent operator intervention of the programmed process operating on the machine tool. The theoretical time for the occurrence of the programmed events is embedded in the machine tool part program. The identity, date and time of the actual occurrence of an event is stored in nonvolatile memory. This technique may be used in a single computer controlling one or more machine tools or in a network with a host computer serving as the event depository and as the source of machine tool part programs. The event records are available for analysis to improve the productivity of the operation.

Abstract: Calcium lactate antibacterial complexes in parenteral dosage forms are provided that are relatively free from tissue irritation following injection, comprising a quinolone or naphthyridine.

Abstract: A temperature control system for an adhesive application system in which adhesive is delivered from a pump to a nozzle for application in bead form to a part. The control system includes a hose assembly extending from the pump to the nozzle and including an inner hose for carrying the adhesive and an outer hose defining an annular space between the outer hose and the inner hose for passage of water in a direction opposite to the direction of flow of the adhesive; a water conditioner selectively heating and cooling the water; and a controller receiving a reference signal representing a desired temperature of the adhesive at the nozzle and an actual adhesive temperature signal provided by a temperature sensor sensing the temperature of the adhesive being delivered to the nozzle and operative to compare the signals and generate appropriate signals for control of the water conditioner in a sense to maintain the desired water temperature and thereby the desired adhesive temperature.

Abstract: A work station for assisting a worker in applying the trim components to a partially assembled seating unit consisting of a seat frame and both seat and backrest cushions. The work station comprises a pedestal for receiving and supporting the seating unit in an inverted position. A vertical compressor is operable to compress the seat bottom cushion while, at the same time, permitting rotation of the compressor and the pedestal about a common vertical axis. This facilitates final installation of the seat bottom cushion trim. In addition, a second essentially horizontal compressor and a pair of manually operable seat back rest trim cover stretchers are provided for assisting the worker in the final assembly of the seat back rest trim to the seating unit. All power assist mechanisms are preferably pneumatically operated.

Abstract: A modulated light beam obstacle detector for use as a safety mechanism in an automatic closure operator which must operate in varying ambient light conditions. If the obstacle detector senses the interruption of the light beam, the motion of the door is arrested or reversed. The obstacle detector uses an auxiliary light source connected in a feedback circuit to maintain a constant background illumination on the light detector and thereby hold the light detector in conduction at all times. In this manner, the presence of the light beam can be sensed regardless of the ambient light conditions.

Abstract: A clevis assembly including a clevis body, a clevis loop pivotally mounted on the clevis body, a collar, a fastener, and a set screw assembly. The collar is externally threaded and threads into a counterbore opening in the lower end of the clevis body. The fastener has a circular head portion which is journalled in a bore in the clevis body with the shank portion of the fastener passing downwardly through the collar. A set screw assembly is positioned in a transverse bore in the clevis body extending between the outer periphery of the clevis body and the bore in which the head of the fastener is journalled so that tightening of the set screw assembly engages the head of the fastener to lock the fastener relative to the clevis body and loosening of the set screw assembly allows relative rotational movement between the fastener and the clevis body.

Abstract: An automatic door operator with a continuously monitored supplemental obstruction detector. In a first embodiment, the obstruction detector is a radiant beam obstruction detector that transmits a beam of modulated radiant energy across the door opening. A safety signal generator produces an active safety signal only on unobstructed receipt of radiant energy by a receiver. Failure to receive the active safety signal when the motor is closing the door at least stops the door. A two wire cable, which carries both power and the active safety signal, connects the supplemental obstruction detector to the automatic door operator. Constant activation of a portable transmitter or of a local push button can override the supplemental obstruction detector to close the door. An alternative supplemental obstruction detector includes a safety edge having a compressible tube disposed on a leading end of the door. Plural conductors change their conductive state upon compression of the compressible tube.

Abstract: A garage door operator has a light which is turned on for a preset period by the controller each time the operator motor is operated. A pedestrian door is equipped with a magnetic switch which signals the controller when the door is opened, causing the light to be turned on for the preset period. A switch console has a vacation switch, a work light switch and a push button which, with the magnetic switch, send signals to the controller. Voltage level encoding and decoding is used to minimize the number of connecting wires between the console and the controller. The controller comprises a microprocessor subject to the switch inputs and programmed to produce output signals for operator motor control and light control.

Abstract: A conjugate electrical connector with improved contact conductivity having slots or grooves in one terminal and rounded protrusions on the opposite terminal. This contact feature provides for two lines of contact points per protrusion/slot pair where the protrusion touches the two edges of the slot whereas the closest prior art only provides one line of contact where a protrusion contacts a terminal without a slot. The amount of energy lost in heat dissipation due to contact resistance is reduced. Additional advantages include: the terminals will lock together with a mechanical confirmation, the terminal will seat in the same place each time it is connected, and movement between the terminals is less likely.

Abstract: A master/secondary clock system of the impulse type consisting of stepper motor driven secondary clocks and a master control unit. At five minutes before a predetermined registration time, for example 6:00, the sensor of each secondary clock movement is activated by a reverse polarity signal from the master control unit and a series of reset pulses are thereafter transmitted to the secondary clocks with each secondary clock stopping as the window in its drive train gear moves into alignment with the emitter and detector of its sensor mechanism. After this five minute pulse reset phase to correct clocks that are five or less minutes fast, the master control unit transmits a rapid pulse train so as to quickly move all of the remaining clocks to the 6:00 position with each clock being halted at the 6:00 position by movement of the window of its gear into alignment with the emitter and detector of the sensor mechanism of that clock.

Abstract: A container especially suitable for bulk materials and including a cardboard tubular sleeve having its lower edge portion positioned in upwardly opening groove means on a plastic pallet. The tubular sleeve is a sleeve assembly comprising inner and outer tubular sleeves respectively formed of first and second corrugated cardboard structures with the inner sleeve positioned telescopically within the outer sleeve and with the outer annular surface of the inner sleeve secured to the inner annular surface of the outer sleeve to form a composite sleeve assembly having a thickness approximating the width of the groove means on the pallet. An auxiliary cardboard sheet is secured to the outboard surface of the outer tubular sleeve and an auxiliary cardboard sheet is secured to the inboard surface of the inner cardboard sleeve.

Abstract: A combination exo-endocervical sampler. The sampler includes an elongated handle portion having a free end and a non-linearly tapered row of flags disposed proximate the end opposite the free end. The flags are preferably configured to have a flat sampling surface and a convex opposed surface and are disposed at an acute angle with respect to the handle portion. A spatulate member is disposed on the handle portion proximate the row of flags at a point diametrically opposite thereto. A ledge extends along the handle member proximate its juncture with the spatulate member and serves to assist in the spreading of the separated exo- and endocervical samplers on to a two-tiered microscope slide. Optionally, a secondary row of flags is formed on an upper edge of the spatulate member to sweep the endocervix and transition zone when the device is rotated within the cervical canal.

Abstract: The connector includes a body, a resilient locking arm provided on the body and with a locking projection at its free end which engages in a connection hole in a panel to lock the connector to the panel, and a lock-up detector. The lock-up detector is provided in a preliminarily engaged state between the locking arm and the body prior to the fitting of the connector to the panel with a length thereof protruded more than the locking projection. When the connector is completely locked to the panel, the lock-up detector is released from the preliminarily engaged state and becomes insertable by a push from the opposite side of the panel to the connector. This enables confirmation of whether a connector attached to the end of a wire harness is completely fitted to a panel, e.g., at a door portion of an automobile from outside the panel and improves the reliability of a connector as a product.

Abstract: A solar panel assembly (10) includes a power generating sheet (22) having two output terminals (30,32), and an electric cable (20) soldered at one end to terminals (30) and (32). A frame member is anchored to the solar panel in overlying relation to the terminals and an epoxy material (62) fills a cavity (58) defined by the frame member (40). A case (42) covers the frame member (40). The case includes an upper member (44) and a lower member (46) which are snap fitted together through apertures in the solar panel. The case (42) includes a tension relieving device which prevents tension on the cable (20) from being transferred to the cable end connected to the terminals (30) and (32). The epoxy provides a water resistant seal which allows the solar panel to be used in hostile environments.

Abstract: Novel glycosides, especially steroidal glycosides, and a novel method of their production, are provided. For the novel method of producing novel glycosides, hydroxysteryl compounds are glycosylated with tri-O-acyl glucal using molecular iodine as a reaction catalyst. In this method an alcohol or phenol, especially a hydroxy-steroid such as a water-insoluble cholesterol, is glycosylated, such that the glycosylation is performed in a single step. The resulting steryl pyranoside is by oxidation converted to the corresponding 7-ketosteryl di-O-acyl-pyranoside. The latter pyranoside is selectively reduced to provide the corresponding 7-.beta.-hydroxysteryl 2,3-dideoxy-.alpha.-D-erythro-hex-2-enopyranoside. The steroidal glycosides obtained in this way possess valuable pharmacological properties. In particular, the glycosides in vivo exhibit a selective cell-destructive activity on malignant cells which activity is substantially free of side effects on normal cells.
