Abstract: ABSTRACT            A prime coated oriented polyester film is disclosed wherein the primer coating is applied as an aqueous medium consisting essentially of a material selected from the group consisting of a water soluble alkali metal salt of an unsaturated fatty acid having from about 10 to 18 carbon atoms and mixtures of such salts or a water soluble alkali metal salt of an alkyl sulfate having from about 8 to 18 carbon atoms and mixtures of such salts.  Preferred species include sodium oleate and sodium lauryl sulfate.        The alkali metal salt priming layer may be applied to the polyester film at any suitable stage during manufacture of the film, i.e., before or during the stretching operations, or after stretching and prior to winding of the film.  The resultant primed polyester film is found to provide excellent adhesion to many aqueous or organic solvent based printing inks subsequently applied thereto.

Abstract: Abstract An electro-hydraulic actuating apparatus for a continuously adjustable servo-valve comprises a regulator which delivers an error signal (F3) depending on the regulating departure.  Upon exceeding their limiting value, two comparators each associated with one direction of adjustment are caused by the error signal to deliver an output signal for operating a control valve arrangement having magnetic valves.  The error signal (F3) is formed by an A.C. voltage with at least one inclined flank, of which the mean value (M) depends on the regulating departure and the half-period is larger than the reaction time of the magnetic valves.

Abstract: ABSTRACT OF THE DISCLOSURE    An aqueous tar sand tailings slurry mixture containing coarse sand, fine particulate solids and bitumen is classified into an underflow of coarse wet sand and an overflow consisting of an aqueous suspension of fine solid particles and bitumen with the aid of a liquid pool on the top flight of a upwardly revolving inclined conveyor belt. The mixture is introduced into the pool on the top flight wherein the coarse sand settles to the surface of the top flight as the underflow and the remaining fine solid particles and bitumen stay suspended in or float on the water of the mixture and flow out of the pool as the overflow.  The underflow is removed by the surface of the revolving belt out of and above the surface of the aqueous pool.  The underflow falls by gravity from the top flight as it passes by the upper conveyor roller   The overflow is collected for subsequent recovery of its bitumen content. The process is particularly suited for concentrating bitumen from mined tar sand tailings.

Abstract: FREQUENCY RESPONSIVE APPARATUS FOR READING A METER               OVER A TELEPHONE LINE     ABSTRACT OF THE DISCLOSURE      There is disclosed a system for reading a meter, e.g., a utility meter, over a telephone line.  The system includes circuitry for detecting when an input signal within a pre-determined frequency range is present.  The input signal is fed to two timing devices   One of the timing devices is set to produce a constant output when the input frequency is above the higher limit of the predetermined frequency range.  The other device is set to produce a constant output when the frequency is above the lower limit of the same range.          The outputs of both timing devices are connected to logic circuitry.  The two timing devices are connected to the telephone line.  When a signal in the selected frequency range is received from the telephone exchange, the frequency detector acknowledges to the exchange the receipt of that signal, and activates a recorder in a meter reading appa-ratus at the subscriber's location to transmit the recorded reading of the meter over the telephone line to the exchange, where it is suitably recorded.  When the first timing device has a periodic output and the second does not, the logic circuitry produces an output indicating that the input signal is within -the predetermined range of frequencies.

Abstract: SUPPORTING TIE CONFIGURATION FOR cryostat FOR COLD                SHIPMENT OF NMR MAGNET     ABSTRACT OF THE DISCLOSURE           A cryostat for use in magnets for NMR medical diagnostic imaging includes inner and outer vessels suspended by sets of at least three low thermal conductivity ties.  The positioning of the tie anchor-ing points, particularly on the interior vessel, are selected in accordance with the present invention to preclude increased stresses in the supporting ties that occur as a result of thermal contraction.  This config-uration is particularly advantageous in that it permits the utilization of ties having smaller cross-sectional areas than would otherwise be required. The reduced cross-sectional area requirement is also therefore seen to increase the thermal isolation of the interior cryostat vessel.  Cryostat vessels may be nested within one another.

Abstract: Abstract of the Disclosure TANDEM CONE BOLT ANCHOR      An improved device for mounting push/pull handles to a door without the use of exposed fasteners.   The device  comprises  an  anchor  with  two  axially  spaced-apart cone sections.   Set screws inserted through the door  handle  bear  against  the  cone  sections  of  the anchor  and  create  a  wedging action  which forces  the door  handle  laterally  toward  and  against  the  door stile. By providing two separate cones in an axially spaced-apart relation, the rotational forces exerted at each set screw when the handle is pushed or pulled tend to cancel each other, avoiding the problem of "hardware wobble" which  loosens  conventional  door  handles  from their mountings.

Abstract: Abstract of the Disclosure A transactional data base processing apparatus which executes plural transactions causing a data base to be updated, incorporates an after-image recovery storage apparatus and method which enables continuous operation of the transaction system.  The after-image recovery storage apparatus has a temporary storage file and a permanent storage file with circuitry for writing from the temporary storage file to the permanent storage file.  That circuitry also writes after-image updating data records to the temporary storage file.  The apparatus further includes elements for initiating transfer of the after-image data records from the temporary storage file to the permanent storage prior to a time when the temporary file is filled with the data records.  The transfer is accomplished by operating the apparatus on a time shared basis so that other ongoing operations including transactional operations occur as the after-image data is being transferred to a permanent storage device.

Abstract: Abstract A semi-automatic directory assistance system uses a directory assistance terminal computer to help an operator at an operator position terminal find the requested directory number.  The control processor, a module control unit, of a module of the system controls the establishment of part of the connection from a subscriber requesting operator assistance to the operator position.  The operator at the operator position communicates with the directory assistance computer to find the requested number.  After the requested number has been found, the computer sends a message to the control processor.  In response to that message, the control processor causes an audio response unit to generate a directory assistance message corresponding to the desired number and causes the response unit to be connected to the subscriber.
