A digital data processing system has a memory organized into objects containing at least operands and instructions. Each object is identified by a unique and permanent identifier code which identifies the data processing system and the object. The system uses a protection technique to prevent unauthorized access to objects by users who are identified by a subject number which identifies the user, ...

A cassette-type magnetic-bubble memory apparatus comprising a bubble cassette which houses a bubble memory device and a main apparatus which comprises a holder into which the cassette is inserted. The contacts of the holder contact the contacts of the cassette in cooperation with the action of inserting the cassette into the holder so that current flows into the bubble memory device. The main appa...

Apparatus and method for sterilizing the interiors of paperboard containers 58, wherein such apparatus and method are operative prior to the container being mounted on a mandrel assembly 24 on which the container bottom closures are formed, closed and sealed. This is accomplished by providing nebulizing means 12 for communicating a suitable sterilant fog through and onto the inside surfaces of the...

An article of furniture is convertible between first and second positions of use as a chair and as a lounge, respectively. A base structure includes two generally U-shaped frameworks each having first and second legs. The frameworks are connected together in spaced parallel planes by a rod connecting the first legs and by a rigid panel extending between and connecting the second legs. The base str...

PURPOSE:To form a reflector composed of metallic films, which has a little variation of a reflection coefficient even if the width would vary slightly, on the reflector of metallic strips on a piezo-electric substrate.

PURPOSE:To reduce the number of required reflecting elements and simplify production by using a liquid-phase epitaxial growth layer having piezo-electric characteristic as a reflecting element.

A continuous extraction apparatus and a continuous extraction process for extracting an extractable component of a liquid or particulate feed material with an immiscible liquid solvent for the extractable component thereof, which apparatus and process are both especially useful for extracting glycerine from soap, utilize an extraction column with oscillatably movable contact promoting means therei...

A document feed-in device for an electronic typewriter comprises a lower guide member for guiding a document towards a typing line on a platen cylinder and a plate or bar member for guiding the document beyond the typing line. The plate or bar member is carried by two movable levers for moving that member away from the platen cylinder and at the same time actuating a switch for signalling the pres...

A filter apparatus is provided which is adapted for filtration of intravenous liquids and separates gas in the incoming intravenous liquid prior to delivering the filtered liquid to a patient. Incoming liquid is passed into a space within a filter holder, which space has a smaller portion that excludes gas due to surface tension forces and a larger portion where gas accumulates. A hydrophobic filt...

Disclosed is a lid lock structure for a hinged lid of a recess which is made in a car body to conceal a fueling port. The lid lock structure includes a latch housing containing a bolt and having a plate spring at its head. The bolt catches a catch leg extending from the back of the hinged lid when closed, whereas the plate spring is yieldingly bent to constantly apply pressure to the lid while it ...
