The carrier for the type element is moved along the print line at a predetermined maximum velocity so long as it is possible to move the type element to the next character in time required to move the carrier from one print position to the next.  If the type character set-up time is greater, the carrier is run at a slower speed and is then returned to the predetermined velocity for printing.

Abstract: ABSTRACT OF THE DISCLOSURE           An electrostatographic processor having a rotatably driven drum for advancing an imaging surface through successive processing stations, a development system charged with a ferro-magnetic developer for developing latent electrostatic images carried by the imaging surface, and a cleaning system including a sump for collecting residual toner removed from the imaging surface is equipped with a toner reclaim system comprising a plurality of permanent magnets which are mounted at spaced apart intervals on one end of the drum to magnetically convey developer from the development system to the cleaning system sump via one non-magnetic conduit and from the cleaning system sump back into the development system via another non-magnetic conduit.  The developer blends with the residual toner while passing through the sump of the cleaning system, with the result that its toner concentration tends to increase, thereby causing residual toner to be mechanically and triboelectrically returned to the development system.

Abstract: Abstract of the Disclosure A fluid flowmeter includes a bluff body for producing vortex shedding free of intermittency.  The body has at one end a support member for mounting in a conduit and has proximate its downstream surfaces a pair of orifices.  A diaphragm, preferably ferromagnetic, is situated in a sensor chamber within the support member for vibrating in response to received pressure fluctuations. A magnetic detector is situated in proximity to the diaphragm for producing an electrical signal when the diaphragm vibrates in response to vortex shedding.  Fluid in the conduit, and thus vortex shedding, is coupled from the orifices through a pair of channels, which are in nonfluid flow communication with one another, to opposite sides of the diaphragm.

Abstract: Abstract of the Disclosure Counting scale and method utilizing a single load cell for determining the weights of both a sample and an unknown quantity of articles to be counted.  The weights are combined to determine the number of articles, and this number is displayed.  The platform of the scale is mounted on and supported by the load cell in a system requiring no levers, pivots or other moving parts.  Weight readings are averaged on a moving average basis, and with no load of the scale, any drift is cancelled by increasing or decreasing the weight readings in small increments during successive counting cycles to maintain an accurate zero reference.

Abstract: ABSTRACT OF THE DISCLOSURE           A walled enclosure or cage is provided in which laboratory animals may be maintained for observation and evaluation.  The floor of the enclosure is provided by a plurality of conductive bar elements that are spacially separate and extend across the bottom of the enclosure. Spacial separation of the bars insulates one form the other and further, space is provided in the floor to remove animal waste, excess food and the like.  An electrical resistor is connected between each two adjacent conductive bars and cooperate with the bars to define a resistor network to which a closely controlled feed current is supplied.  An animal makes contact with the conductive bars which lowers resistance of the network and produces a voltage change.  The resistor network is a.c. coupled to a differential amplifier, and a comparator which receive pulses from capacitors between the network and the amplifier and prepare same for an interface means for a pulse recording system.  The amplified pulse may be shaped, divided or the like as required by the recording system.  The method of using the present system involves detection of contact between an animal foot and the conductive grid bars, whereupon contact area determines the resistance of the network and a proportional signal is produced therefrom. The signal is then amplified, manipulated to avoid ambient electrical interference, such as an incidental electrical field from line current at 60 Hertz, and/or shaped, divided or the like to provide input to a particular recording system.  Raw data from the recording system can then be correlated to locomotor activity of the laboratory animal.

Abstract: SHOWER HEAD     Abstract of the Disclosure:           A shower head is disclosed for regulating water flow.          Improvements enable a constant shower spray to be produced even though changes may occur in the pressure in the main lines.  Accord-ing to the invention, this is brought about by arranging outlet holes of the shower head in a flexible diaphragm-like disc held in the shower head casing by its edge.  This disc reacts to slight changes in main line pressure to flex and adjust the volume of water within the head, thereby adjusting the resultant pressure within the head to compensate the change to main line pressure.  This flexure of the disc also dislodges lime deposits and the like from the outlet holes, thereby providing a self-cleaning function.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for cleaning the matrix of a magnetic separator, the cleaning being carried out by means of a fluid medium.  In a known similar apparatus, a larger path-time portion, associated with a corresponding decrease in through-put power of the separator, is required for the clean-ing. Additionally, the use of large liquid volumes make it necessary to use more expensive clarifying and separating appara-tus in order to separate the obtained solid material from the cleaning liquid.  The present invention provides an economical manner for washing out the magnetic separation space of whole-back separators, the method being both qualitatively and quan-titatively improved over known processes.  According to the process, the method includes the step of cleaning the matrix of the magnetic separator by means of a fluid medium and a compressible cleaning medium. The apparatus comprises an entry chamber sealed to an entry end of a matrix, the entry chamber having attachments for introducing a cleaning media.

Abstract: Abstract of the Disclosure An indicating apparatus for measuring the pressure of a fluid within a container, such as a tire, which includes a housing having one end adapted to be mounted on the tire valve assembly.  The housing has a range of scale indicia thereon extending from a minimum valve to a maximum valve representative of the pressure of the fluid within said container between a predetermined range of pressure.  A collar is mounted onto another end of the housing, and a sleeve is supported within the housing having opposite clamping ends that secure the collar in nested relation to the housing.  A plunger is supported within the sleeve for movement between an inoperable position wherein the tire valve is closed and a first operate position wherein the valve is opened  to permit fluid from the tire to enter the housing.  An indicator piston is supported within the housing for movement to an indicating position relative to said scale indicia to provide a reading representative of the pressure within the tire, which position is exposed to view through the housing.  The apparatus further provides for movement of the plunger to a second operate position wherein the valve is opened to permit pressure from an external source to be transmitted to the tire through the  housing  without having to remove the apparatus from the tire valve assembly.
