An apparatus for supplying fluid of predetermined quantity comprises a supplying passage for supplying fluid, an opening and closing valve provided within the supplying passage, mechanism for opening the opening and closing valve, locking mechanism for locking the opening and closing valve in an open state, negative pressure generating mechanism for generating negative pressure upon supply of the fluid outside through the supplying passage, lock releasing mechanism for releasing the lock of the ...

A direction indicating device has an azimuth card which is positioned upon a compass. The card is provided with a number of indicia marks corresponding to specific geographic locations. An adjustable straight-line cursor is positioned to be aligned with an indicia marking corresponding to the geographic location at which the device is being used and with the pivot point of the compass magnetic needle such that when the compass magnetic needle is pointing to magnetic North, the straight-line curs...

A working implement such as a rock drilling apparatus is automatically positioned to predetermined positions and/or directions. Particularly, a drill bit is moved to an imaginary plane spaced from the surface to be worked upon completion of a drill hole by programming the predetermined positions such that they are in said imaginary plane. The actual values of the position and/or direction of the working implement may be adjusted simultaneously toward set values corresponding to the predetermined...

A container with a threaded neck portion is adapted to be closed with a closure engaging the threads of the neck portion. The threads of the neck portion have at least two stops disposed at opposite ends of the threads. The threads may be continuous or interrupted but have a maximum pitch of 8 degrees. The two stops of the threads on the neck portion insure that the closure is stopped at a predetermined position relative to the container after full-threaded rotation of the closure onto the threa...

An electronic control circuit for use with a remotely operated tape recorder wherein a rewind command is issued and executed upon energization of a power source.

An apparatus for machining a workpiece to a predetermined contour in accordance with a reference pattern comprises a cam mechanism which defines the reference pattern. The cam mechanism is mounted on a carrier assembly, on which is mounted a rotary workpiece holder for positioning a workpiece in relation to a machining tool. The cam mechanism is coupled to the workpiece holder by drive means and is driven so as to impart an oscillatory pivotal movement to the workpiece holder while rotating the ...

In a camera using a zoom lens for effecting zoom photographing at a predetermined photographing magnification, a detecting apparatus detects distance to an object moving along the optic axis of the zoom lens and detects speed of the object. A control device causes the detecting device to detect the distance to the object and the speed of the object repetitively as long as an operation signal (e.g., a signal from a shutter release button) is produced, repetitively predicts the distance to the obj...

Disclosed is a method for producing a predetermined cesium compound. The method comprises treating a cesium-containing material with a suitable reagent to dissolve at least a portion of the cesium contained in the material and form a slurry; adding a base comprising slaked lime or calcium carbonate and an acid containing the anion of the predetermined cesium compound to the slurry comprising the dissolved cesium; and separating the predetermined cesium compound. In one embodiment of the inventio...

A computer-based facility configured for programming of numerically controlled (NC) machines includes an NC data set generator component used in allowing a user to select data sets for NC programs that control the NC machines. For example, such data sets may include features, processes, tools, and functions combined in accordance with predetermined practices, such as best practices. Aspects of the facility allow for integration of generated data sets into a computer aided drafting/computer aided...

A method of conducting polymerisation reactions on a rotating surface reactor which allows substantially increased conversions (up to around 99%) to be achieved without a corresponding increase in polydispersity as would be expected as a result of the Trommsdorff-Norrish effect. The rotating surface reactor serves to disentangle and/or stretch growing polymer chains so as to result in better control over polymerisation kinetics.
