Method and apparatus for controlling the thickness of vertically drawn sheet glass. A scanning pyrometer periodically observes the temperature of the glass in a series of zones across the drawing area at the meniscus through which the sheet is drawn. A muffle having a plurality of corresponding temperature control zones extends transversely above the stream of molten glass flowing into the drawing area. The temperature of the glass flowing beneath each zone of the muffle is individually regulate...

A method is disclosed whereby estrus is induced and ovulation is regulated in domestic animals by administering a prostaglandin derivative of formula 1a or 1b, ##SPC1## In which R.sup.1 and R.sup.2 each are hydrogen or lower alkyl, to the animal during the functional life of a corpus luteum of said animal.

A motor speed regulation system employing integrated and discrete semiconductor components, in which either a direct drive signal or a digitally incremented biasing signal is applied to the motor to bring it up to speed or to maintain it at a desired speed under load.

A system is disclosed for providing a desired energizing current, according to a reference current signal, to a load or group of load elements. Three phase energizing current is rectified by a plurality of controlled switching devices such as thyristors, and means are provided for varying the firing angle of the thyristors in accordance with the reference current signal to regulate the resulting output voltage therefrom and thereby regulate the energizing current through the load. Digital transm...

The pitch of orientable blade pumps at various stations along a pipeline and valving at the stations are regulated to conform pressures and flow rates in the pipeline to accommodate the upper limits tolerable in the section under most stress compared to its capability. The process is especially useful where fluids of differing viscosity are to be successively pumped. By preference, the process is practiced to provide an output at the delivery terminal with either a constant flow rate or a consta...

A switching regulator power supply which provides operating voltage for a deflection system which in turn provides the ultor voltage for a picture tube and which ultor voltage is subject to variation caused by picture tube beam loading is controlled by a single pulse, the timing of which synchronizes the regulator operation and the width of which is determined by a bias level on a transistor which is coupled to a pulse differentiating network, the bias being determined by the level of an ultor v...

New arylisothiocyanates corresponding to the formula ##STR1## wherein R represents alkyl, alkoxy or halogen X represents oxygen or sulfur and P represents an integer of from 2 to 5 are disclosed. They can be used for the regulation of plant growth especially for the dessication and defoliation of unlignified parts of plants above the soil.

The present invention provides a staphylococcal accessory regulatory protein sar, and the gene encoding that protein(sar). This protein relates to the recognition and control of bacterial infections, particularly infections caused by Staphylococcus aureus (S. aureus). The sar protein and gene are thus useful in preventing or treating staph infections, and in diagnostic kits and assays for detecting the presence of the sar protein and sar gene.

An autonomous electric watch comprises a receiver for picking up a magnetic or acoustic coded regulation signal delivered by a telephone set, and a control circuit automatically controlling memory circuits of the watch to regulate the frequency and/or set the time displayed in response to reception of such a signal. The regulation signal is provided by a signal generator connected to an automatic telephone reply apparatus that can be called from any subscriber telephone set, and may be combined ...

The invention disclosed is a circuit for regulating optical power levels. Electrooptic attenuators are used to control optical output intensity by means of feedback loops from the outputs of the attenuators to the electrodes of the attenuators which determine the amount of light going to the outputs. The attenuators may be used in combination with an optical switch array in a wavelength division multiplexing system.
