A container of evacuated double wall construction has an open neck for receiving a beverage after the beverage has been heated to a desired temperature. A stopper member receivable in the open neck incorporates an evacuated electric light bulb covering a major portion of the cross sectional area of the neck to provide further heat insulation and also radiate heat onto beverage within the container. Regulation of the heat to maintain the beverage at a desired constant temperature is accomplished ...

A system for maintaining a diesel engine is disclosed herein. The system includes a timing light and tachometer.

The invention is a system for a printing press which maintains the density of the colored ink put down on a moving paper web. The system includes a scanning device having a strobe light for illuminating a color patch in a color bar which runs transversely across the web, a camera for photographing the illuminated color patch and a step motor for moving the scanner incrementally across the web. Actuation of the scanner is timed through a microprocessor using input from an optical sensor and encod...

A constant tension winching mechanism which has a friction clutch interposed between the drive member and the drum of the winching mechanism. A conduit system is connected to the clutch for directing a cooling media thereinto and therefrom so the clutch will not be damaged by the heat generated by continuous slippage. A variable controller is provided to control the degree of engagement between the friction elements within the clutch, which controller may be either manually or automatically oper...

A prosthetic device for controlling urinary continence is disclosed. The device has an opening pressure that varies in response to changes in physiologic parameters. The device can be controlled by the patient voluntarily without manual intervention. An introducer for transurethrally introducing the device is also disclosed. In addition, a nonsurgical or minimally invasive method of positioning the device for maintaining urinary continence is disclosed.

A driver alertness maintaining device that includes timer/output mechanism circuitry that is programmable by the user to select and repeatedly output an audible alerting message through a speaker at a user selected interval; the driver alertness maintaining device further including a device housing including a circuitry compartment for containing the timer/output mechanism circuitry; a time display unit responsive to a display output signal from the timer/output mechanism circuitry; a visual ala...

Force maintaining toggle systems wherein maximum or near maximum force is maintained by a series of step wise toggle engagements. The forces may be applied between spaced objects arranged oppositely or circularly.

An apparatus for maintaining an electrophotographic apparatus with at least a photosensitive member comprises a first memory for storing a count value for the number of prints, and a second memory for storing the number of replacements of the first memory when the count value for the number of prints has reached a value based on which a decision is made whether the service life of the photosensitive member is expired. When it is determined that the value stored in the second memory has reached a...

A method and composition for preventing a tear, hole or run in hosiery from expanding, wherein the composition comprises: (a) nitrocellulose, (b) resin, (c) dioctylphthalate, and (d) a solvent or solvent mixture.

The inventive device includes a support shaft having a longitudinal axis with a locus that does not change, including when the shaft is positionally rotated about such axis. A collar is mounted on the shaft for supporting an idler pulley having an axis of rotation. An indexing plate is also mounted on the shaft for maintaining a selected position of the collar, the angular position of which is adjustable. An indexing surface is in position-affecting relationship to the collar and defines a plane...
