Abstract: ABSTRACT OF THE DISCLOSURE         In a safe deposit apparatus of the type having a horizontally pivoted sector-shaped door with an interior pocket formed by a pivoted wall serving to eject articles from the pocket when the door is closed, the pivoted wall is normally biassed to the pocket-forming position and is displaceable therefrom to the ejecting position by a cam arrangement which becomes operable as the door is closed.          Another cam arrangement maintains the pivoted wall in the ejecting position during opening the door.  A locking mechanism permits opening of the door to a first position at which envelopes may be deposited, but prevents opening to a second position for the deposition of wallets except when released by a user's key.

Title: Dot matrix character printer  with variable speed control

IPC: G06K15/10
Filed: 1979-10-26
Granted: 1982-08-24
Abstract: Abstract of the Disclosure A dot matrix character printer having the capability of printing characters at variable speeds and with variable pitches.  Variable pitch is provided through the use of programmable radix counters which control actuation of the printing solenoids.  Solenoid actuation is based on print head position, with the actuation position being varied with print head velocity, to compensate for the distance travelled by the print head during the time between solenoid actuation and print wire impact; this permits operation at variable printing rates.  Printing rate is limited by the cyclic rate of the print head, with an additional limitation based on dot printing density which prevents excessive heating of the printing solenoids.

Abstract: ABSTRACT           The present invention relates to composite materials, to methods of producing articles from such materials, and to articles produced from such materials.          Powder-based binders (especially binders based on Port-land cement) are improved by adding powders which are one or more orders of size finer than the binder powder.  This forms the basis for a homogeneous and dense particle packing with an extremely finely porous structure.  Large amounts of surface active dispersing agents are added to secure a very homogeneous particle arrangement and high particle concentration.   The binders so obtained show improved strength, density, durability, and offer improved fixation of reinforcing bodies than unmodified binders.  Shaping of articles comprising such ginder matrices is possible by use of a low stress field and without exchange of material with the surroundings.

Abstract: A B S T R A C T     A constant-speed continuously-running low-powered diesel engine or turbine drives a two-phase alternator, the output from which, for direct drive, flows to the stator pole piece windings of four independently-rotating stepping motors operating syn-chronously with the alternator. Each stepping motor is connected to a traction wheel of a motor vehicle, thereby propelling at limited maximum speed sufficiently to overcome normal wind resis-tance over a level road. In starting, during acceleration, and for propulsion at lower speeds, direct current from a storage battery is caused to pulsate and is added to the current from the alternator to the stepping motors. A control circuit selec-tively controls the frequency of a variable frequency generator electrically connected to the pulse-responsive electrical power system to vary the frequency of the current supplied to the step-ping motors and thus vary the vehicle speed. During idling, the alternating current from the alternator is rectified and recharges the battery. During braking, the consequent driving of the step-ping motors causes them to generate alternating current which is rectified and returned to the battery. By varying the frequencies of the current delivered to the right side motors as compared with those delivered to the left side motors and vice versa, in response to the turning of the steering wheel in rounding a curve in the road, a differential action is obtained.      In a modification, combustion of fragmented slow-burning solid fuel, such as wood fragments, in the combustion chamber of a portable combustion receptacle or pressure vessel mounted on the rear of the vehicle, is initiated by igniting in the combus-tion chamber combustible starting fluid gas, such as propane gas from an external source and ignited by a spark plug. Air is sup-plied by an air compressor driven by a prime mover such as a turbine or electric motor. As soon as combustion of the solid fuel has become self-sustaining, the supplying of this starting gas is terminated. Meanwhile, the pressurized gas emitted from the burning solid fuel in the combustion receptacle is discharged into the power turbine by way of a throttle valve. The output shaft of the turbine drives a speed-reducing transmission which in turn drives the alternator.

Abstract: ABSTRACT OF THE DISCLOSURE         A method is provided for the explosive welding together of sections of large diameter metal pipe of the kind used in the construction of high volume oil and gas pipelines.          In the method, internal and external band charges of welding explosive are simultaneously detonated adjacent to overlapped telescoped pipe ends.  The welding charges are detonated simultaneously by means of very high detonation velocity initiation explosive charges placed along a leading edge of each welding explosive charge.  The initiating explosive charges are each set off by a single detonator means.          The velocity of detonation of the initiating explosive is selected so that welding charges are simultaneously detonated around the pipes while maintaining the detonation fronts at superimposed locations and at a large angle to the pipe axis.        This avoids unbalanching forces on the pipes and minimizes the collision of circumferential shock waves thus preventing pipe damage and imperfect welds.

The insert also has a second surface  above  and  spaced  from  both  the  first  and resting  surfaces  by  an  arc-shaped  elongated  stepped opening facing in the direction of disc rotation and curved or scooped toward the disc surface.  A multi-fingered cutter blade is secured to the second surface and has a plurality of cantilever spaced fingers sub-stantially as wide as they are high with each finger bent  to contact  the resting surface and each  finger has a cutting edge facing in the direction of rotation such that the fingers are rigidly supported at their ends  to  avoid  distortion and  cut  adjacent elongated strips  and direct  them downwardly on disc  rotation.

The  overall  ar-rangement is a rigidly supported cutter that does not distort and cuts evenly spaced elongated strips suit-able for french fries and directs them downwardly away from the cutting disc.

Abstract: ABSTRACT      A printer subsystem receives command and data information from a host system and retains a large number of font images in an associated storage area within the printer subsystem.  A base font image set is ordinarily selected by the user but provision is made to dynamically change the font images as may be required in a real time fashion during actual printing operations.  The font images are stored in a com-pressed form in the storage area.  Routines involve the use of pointer tables and data tables.  It is possible to select an entire set of new font images in place of the base set of images or to modify only selected character images within the base font image set.

Abstract: Title:  MECHANICAL PROTECTION COATING         FOR COATED METAL SUBSTRATE     Inventors:  ERGO KARUKS and MARTIN ROHN                ABSTRACT OF THE DISCLOSURE     A cementitious coating is applied to a thin smooth, corrosion-protective coating of a pipe to protect the corrosion-protective coating against physical damage and hostile environments.  The cementitious coating adheres to the corrosion-protective coating, is typically between 0.5 and-5.0 millimeters in thickness, and contains a cementitious material such as port-land cement, a polymeric material such as an acrylic polymer, and may also contain chopped fibres such as glass fibres and a filler material such as silica sand.  The cementitious coating has sufficient conductivity to permit a cathodic protection current to flow therethrough.  The cementitious coating may also be applied to the corrosion protective coating of the metal substrates.  Polymer bonded coatings may alternatively be so applied, to protect the corrosion protective coating.
