Title: Apparatus for controlling the feed rate and batch size of a material feeder
Inventor: WRIGHT THOMAS J JR
IPC: G01G11/12
Filed: 1976-04-15
Granted: 1979-02-13
Abstract: Abstract of the Disclosure Apparatus for controlling the feed rate and batch size of the material feeder is disclosed.  A signal generator means computes the weight of material delivered y the material feeder and compares it to first and second presettable values. When the weight of material delivered by the feeder is less than the first presettable value, the signal generator enables a first pulse generator which generates a pulse train having a relatively high pulse repetition frequency.  This pulse train is applied to a motor speed controller which causes the feeder to deliver ma-terial at a relatively high rate.  When the weight of material delivered by the feeder reaches the first presettable value, the signal generator enables a second pulse generator and disenables the first pulse generator.  The second pulse generator generates a pulse train having a pulse repetition frequency substantially lower than that of the pulse train generated by the first pulse generator.  The second pulse train is also applied to the motor speed controller which then caused the feeder to deliver material at a relatively low rate.  Finally, when the weight of material delivered by the feeder reaches the second presettable value, the signal generator generates an end of batch signal which disenables the motor speed controller and causes the ma-terial feeder to stop delivering material.

Abstract: ABSTRACT OF THE DISCLOSURE     Architectural or decorative pavement having thin decor-ative pavers or "titles" made of or selected from known materials, from metal and impregnated wood to natural stone to clay or cement-itious tiles, are bonded to the upper surface of a sand and cement (and latex, if desired) detting bed before the bed takes its initial set. "Thin" pavers are less than 1-1/4" thick.  Stronger materials in these pavers lend themselves to minimum thickness in small to medium sizes.  Thin pavers of weaker materials require maximum thickness in large to medium sizes.         The pavers are placed in rows and designs as may be pleasing with adjacent side edges spaced apart and forming gaps all around the perimeter of each paver.         While the bed and bond are both green, vertical cuts are made through and below the gaps and through the bond cost and appreciably into the setting bed all around the whole peri-meter of each paver.  The setting beds are supported on approp-riate bases or other supporting means.         After the paving is cured the cuts in the setting bed create a stress line below which destructive forces exerted on the finished pavement are concentrated to vertical downward extensions of the cuts to the full depth of the bed, and form, in effect, whole,separate, monolithic fractured-out pavement blocks which may suffer bodily displacement while preserving the integrated pavers whole and intact.         The cuts into the setting bed, or the cuts and subjacent cracks comprise by their numbers and proximity, expansion and control joints.

Abstract: ABSTRACT       Disclosed is a system for visually and magnetically recording data indicative of characters on opposite sides of a paper sheet having a magnetizable backing.  The data are recorded with a typewriter which includes a head for recording coded magnetic bits indicative of each character visually printed on the sheet.  The head is coreless and is comprised of a plurality of windings, only certain of the windings write or record bipol-arity magnetic bits onto the backing, the remaining windings serve as both spacer and erase windings.  Recording is accomplished by feeding large amplitude, short duration current pulses to the recording windings.  The magnetic bits for each magnetically recorded character are selectively erased by applying bipolarity, low duty-cycle pulses of successively lower amplitudes to the backing by way of the windings and different modes of erasing various areas on the recording medium are disclosed.  Also dis-closed is a system for decoding the magnetic bits stored on the backing, wherein a head sequentially scans a rotating line of magnetic bits and sequentially reads out each character of the line.  The entire document is read by stepping the head from line to line.

Abstract: ABSTRACT     For use in business machines, one-piece holders or cartridges are described for holding spools or cores carrying inked ribbons or coated film ribbons.  Each cartridge, although a single permanently integral unit, enables each spool or core to be located in operative positions removed and replaced, the spool or core being located in the cartridge by flanges at its opposite ends, and at least one of these flanges being sufficiently resilient to permit the spool or core to be removed.  In one example, a neck at one end of a core can be moved along a slot in one flange to locate a shallow journal in a recess at the end of the slot, the opposite end of the core being located by a bearing hole in the other flange.  In another example, a circular flange formed at the end of each spool is journalled in a shallow depression in one cartridge flange in which it is retained by a resilient cartridge flange bearing on the opposite end of the spool.  The spools or cores are arranged so that they can be positively driven by the machine mechanism.

Abstract: VEHICLE LOCATION SYSTEM                ABSTRACT OF THE DISCLOSURE    An improved system of the type wherein the precise location of a vehicle is determined.  The system includes a plurality of fixed position transmitters which are predeter-minedly positioned along the intended route of the vehicle.          Each transmitter broadcasts a sequence of data bits representa-tive of its particular location, over a directive antenna.          A receiver within the vehicle detects nearby transmitters and decodes the data bits, thereby establishing the vehicular general position.  The precise vehicular location is established by logic circuitry which processes variations in the signal strength of the received signal along with position pulses generated by an odometer sensor at predetermined increments of vehicular travel.  The logic circuitry produces an output detect signal corresponding to the precise vehicular position during which the vehicle is directly opposite the transmitter.

Abstract: 19.8.77 ABSTRACT:         A charge coupled device of the bulk CTD type, which is used as an electronic variable delay line for video frequency signals.  The clock frequency is varied from 15 to 35 MHz.  The charge packets are formed by integration of the input signal current over the en-tire clock period of the clock signal.  As a result, the cross-talk of the clock signal to the input sec-tion does not affect the video signal to be processed. Furthermore, the non-linear characteristic of the in-put current source is linearized by negative current feedback with the aid of an operational amplifier.

Abstract: ABSTRACT OF THE DISCLOSURE           A light metal die-cast head and cast iron block employ a low volume cooling system which cooperates with the differing thermal conductivity properties of said head and block.  The cooling concept eliminates the conventional intricate water jacket and replaces it with continuous grooves which wrap hemi-cylindrically about each combustion cylinder in a thinly spaced relation.  The grooves are exposed along their length at the deck surface of either the head or block.         The total fluid mass in the system is reduced to as little as 1/5.  There are two such grooves in the block which (a) extend from one end thereof to the opposite end, (b) are on opposed sides of the cylinder galleys and (c) have sub-stantially no transverse flow in order to promote laminar or controlled flow.  There is a critically located straight drilled passage along with two such grooves in the head, the combination of which is restricted in throat area when com-pared to the throat area of the grooves in the block; this results in a high velocity flow in the head and a low velocity flow in the block when they are connected in series flow relation.  The straight longitudinally drilled passage (which may include one or more of such passages) is located in the head separating the exhaust and metal valve guides; the passage has a throat area equal to or less than the throat area of either of the grooves in the head.  Heat extraction is more easily and flexibly programmed to achieve not only a more uniform wall temperature throughout the head and block, but permit a desirably slightly higher average wall temperature than conventional light metal heads for improvement in fuel economy and thermal efficiency.
