Abstract: ABSTRACT OF THE DISCLOSURE           A charging device for use in electrostatic copying machines to charge and discharge the photo-sensitive drum or transfer paper is disclosed which eliminates the adherence of toner powders to the charging wire.  The performance of the charging device is improved and required maintenance is reduced.  In conventional charging devices, toner powders tend to adhere to the charging wire during operation reducing the discharge performance.  The toner powders may adhere to the transfer paper, or may re-adhere to the drum and maintenance is required.  The charging device disclosed incorporates a piezoelectric vibratory element which applies a vibratory motion to the charging wire for a specified duration.  Alternative embodiments utilizing magnetic means for vibrating the charging wire are also disclosed.

Abstract: Abstract A sheet feeding device for separating a single sheet from a stack of sheets and forwarding the separated sheet away from the stack is disclosed which employs an endless friction belt cantilevered about a drive pulley such that the unsupported end of the belt floats freely on a stack of documents or paper sheets when the belt is in the feeding position.  As the belt is driven about the pulley the unsupported end of the belt pulls and advances the foremost sheet from the stack and advances it over a retard member on which the unsupported end of the belt also floats.  Because the belt floats freely on the stack of sheets, the normal force is evenly distributed over the surface of the belt, intersheet coupling is minimized, and the belt is able to conform to changes in the paper and stack condition.

Abstract: PROCESS FOR CONTROLLING PATTERNS OF CHEMICAL STIMULI ADMINISTRATION TO BIOLOGIGAL TISSUE            ABSTRACT OF THE DISCLOSURE A process mimics in-vivo or other conditions to a biological tissue that has been isolated from its natural nutrient supply by controlling the concentration of chemical stimuli delivered to the tissue.  The process includes starting with a first known volume of the supportive media, having a known concentration of chemical stimuli affecting the tissue at an initial known point in time.  Simultaneously, a first known volume and known amount of the chemical stimuli is removed from affecting the tissue and a second known amount of the chemical stimuli is added in a known volume having a known concentration different than the concentration of the chemical stimuli initially affecting the tissue.  The volume of the supportive media is then determined along with the resulting concentrations of the chemical stimuli affecting the tissue.  The above steps are repeated resulting in the concentration that affects the tissue being known at each and every point in time.  In delivering the chemical stimuli to the tissue, the volume of the supportive media supplied to the tissue, the rate of delivery, rate of removal of the media along with the initial concentration of the chemical stimuli and the concentration of the chemical stimuli being supplied is used to determine a desired administration of the chemical stimuli such that the concentration affecting the tissue emulates the desired fluctuations of the chemical stimuli with respect to time.  With these parameters defined, the concentration affecting the tissue with respect to time is known at each and every point in time.

Abstract: Abstract:   The invention provides a resonance absorption type silencer provided in a motorcompressor for a refrigerator.          The silencer comprises a blind cylindrical bore provided in the cylinder block of the compressor.  A valve plate at the end of the cylinder has a bore which allows the cooling gas to communicate with the bore.  The transverse dimension of the opening is smaller than the diameter of the cylindrical bore.  In this way, the silencer is not only effective, but is inexpensive to produce and does not take up any additional space within the motorcompressor.

Abstract: ABSTRACT OF THE DISCLOSURE           A position control system for controlling a motor-driven mechanism capable of occupying a plurality of specified positions comprises a plurality of switches  for specifying a position to be occupied by the mechanism and an encoder for generating a specified position signal representative of the specified position and a loading circuit for providing a present position signal representative of the position presently occupied by the mechanism.  A read-only memory circuit uses the specified and present position signals to provide a control signal for controlling the motor to move the mechanism to a particular position and a comparison signal and a particular position signal indicative of that particular position.  A position detector responsive to the position of the mechanism provides a detection signal representative of the particular position when the mechanism reaches it.  A comparator compares the comparison signal from the memory circuit with the detection signal and provides a match signal to the loading circuit when they coincide.  In response to the match signal the loading circuit loads the particular position signal into the memory circuit as the present position signal.  If the particular position signal matches the specified position signal, the memory circuit provides a control signal that stops the motor.  If the particular position does not match the specified position signal, the memory circuit provides a control signal to actuate the motor again.  The illustrated embodiment of the system provides a tape recording and reproducing apparatus with four different operating modes.

Abstract: ABSTRACT OF THE DISCLOSURE      Brake apparatus for a railway vehicle including a brake cylinder device of the type having a pair of interconnected pistons of unequal size to which the vehicle brake rigging is connected.  The larger power piston forms an application chamber and a release chamber on its opposite sides in which air is stored for use in controlling the vehicle brakes.  The release chamber air is vented to atmosphere during a brake application by way of an empty/load brake control valve device including a changeover valve and a pressure sensitive check valve.  When the vehicle is empty, the release chamber air is vented by way of the check valve, which limits the maximum reduction of release chamber pressure and accordingly stab-fishes the maximum empty vehicle brake force obtained.  A load piston biases the check valve with application chamber air, which is charged from the brake pipe so that the check valve bias and consequently the maximum reduction of release chamber pressure reflects the train charge.  The empty/load control is protected against false transitions of the change-over valve due to car jounce and rock by a delay choke and an exhaust shut-off valve in parallel with the foregoing check valve and changeover valve.
