Abstract: ABSTRACT OF THE DISCLOSURE.    A method of producing a lead-acid battery capable of activation by the addition of electrolyte thereto, comprises the steps of starting with a battery container accommodating at least one pack of battery plate grids having insulating separators interposed between adjacent grids, each of said grids carrying the lead-acid battery paste required to produce a positive or negative battery plate after conversion of the paste into the active material of the plate.  With the grids immersed in an aqueous solution of sulphuric acid, an electric current is passed between the grids so that the solution rises to a temperature in excess of 180°F but not greater than 210°F, the passage of the electric current converting the paste on the grids to the active material of the plates.   The passage of the electric current is ceased when sufficient of the paste has been converted to provide the plates with a charge in excess of 50% of the required final value and the plates are then allowed to stand in said solution for at least 15 minutes.          The passage of an electric current is then repeated so as to produce a charge on the plates of the required value, whereafter the sulphuric acid solution is drained from the plates and the container is sealed against the ingress of air.

Abstract: ABSTRACT           The apparatus for transferring manure normally comprise pumping means having hydraulic cylinders and a system of valves which permits the pumping of the manure during the forward course, but prevents the suction of that material during the reverse run.      In this invention we use a hydraulic assembly provided with a mobile pumping chamber in which a piston is activated by a cylinder, and another hydraulic assembly having a rod connected to the said mobile chamber. A connecting frame between the cylinder of the first hydraulic assembly and the cylinder of the second hydraulic assembly can pivot in respect to a hopper, where these two assemblies are normally located.  In this way, when necessary, the complete removal from the hopper of the two hydraulic assemblies becomes possible.

Abstract: FACSIMILE COMPRESSION SYSTEM     Abstract of the Disclosure Disclosed herein is a data compression system for compressing binary facsimile data to reduce transmission times over standard telephone system circuits.  At the transmit end of the circuit a segment of adjacent scans of, e.g., a white or light background document having, e.g., black typewritten characters or other symbols thereon is stored in a binary format in a buffer memory.  A scanner scans the memory to locate the position of a beginning point of each individual character.  A block definer circuit then defines a rectangular block closely enclosing the character.  A block mapping circuit then scans the block following a pre-determined pattern and provides a binary sequence of the black and white portions thereof.  A run length encoder may then encode the binary sequence by run length or by Huffman code.  A modem connected to the telephone lines sends data corresponding to the location, size and contents of each character block to a receiving modem at the receive end of the telephone circuit.  There the coded binary sequence is decoded by a run length (or Huffman) decoder.  A signal restoration memory receives and stores each character block according to sent location, size and binary sequence.  A restoration scanner then scans the restoration memory to provide a reconstructed binary facsimile signal in conventional foxmat.  For additional compression, the system may include a transmit library memory for storing initially scanned blocks of different individual characters.  A receive library memory at the receive end of the circuit is loaded with the same character blocks.  Thereafter, a character identifier circuit compares each subsequently scanned block against the characters in the library.  Upon a parity  detection, an abbreviated library address is sent in lieu of the run length encoded block data.  The character data stored in the receive library memory at the sent address is then output to the signal restoration memory in place of the unsent block data for that character.  The system repeats the foregoing func-tions until all portions of original documents have been sent and received.                          - b -

Abstract: GRASS SPORTS SURFACES AND A METHOD FOR MAINTAINING THEM     Abstract of the Disclosure A level unobstructed grass sports and recreation surface wherein the grass is deeply rooted in a layer of sand overlying a layer of gravel and preferably nurtured from below to provide a controlled growing environment exhibiting vigorous growth.          The sand has more positive vertical liquid flow characteristics whereas the gravel has better horizontal liquid flow character-istics and the appropriate gradation selection of both determines the high drainage ability and uniform fertilizer/irrigation distribution throughout the system.  The grass surface is defined by a water tight membrane extending from the perimeter, adjacent the surface and completely underlying the gravel layer.          Control means are provided to detect the liquid level contained within the membrane and add or remove liquid to maintain the appropriate level.  The buried conduit system is used for the controlled addition of water/fertilizer and excess drainage removal.  The nutrified liquid from the reservoir is hydro-ponically supplied to the roots of the grass on a continuous demand basis.  Heating cable may be placed at the boundary zone on top of the gravel and sand layers to warm the sand to remove frost and melt snow.  An insulation layer may be placed be-neath the membrane to minimize frost penetration to the sub-grade.  The system may be either completely automatic and pro-grammed to accommodate external conditions such as degrees of use of the field, climatic conditions or the like or alternatively may be partially automatic and supported by more standard methods.     Coupled with the control system can be a sensing unit to determine automatically the nature of the contained liquid.

Abstract: ABSTRACT OF THE DISCLOSURE      A memory subsystem for processing memory requests includes at least a pair of independently addressable dynamic memory module units. Each memory unit includes arrays of memory elements corresponding to a number of storage locations, separate addressing and data output circuits.  The system further includes common timing, refresh and control circuits.  When the memory request specifies a predetermined type of memory operation, the control circuits generate signals for refreshing a location within the memory unit from which data is not being fetched.  The control circuits,upon the completion of  he refresh operation, in response to another prede-termined memory request, refreshes the corresponding row within the other unit in parallel with fetching data from first unit.  Upon completing refresh operations within both units, the control circuits generate a control signal for inhibiting the refresh circuits from performing a mandatory refresh operation, upon a row of memory elements within the memory units in which access to the memory system is inhibited temporarily, enabling memory operations to continue without interruption.

Abstract: Abstract A heretofore undiscovered suddenly conducting avalanche voltage effect is described with relation-ship to a new family of hybrid transistors which exhibit both lateral bipolar and field effect characteristics.  The devices constructed also ex-hibit magnetic sensitivity.  The magnetic respon-siveness of such devices creates a new family of magnetic sensors which utilize magnetic modulation of the avalanche voltage produced by the new effect. New transistor structure elements are incorporated in the devices.  These include an impact ionization promoter means and an intrinsic, or high resistivity, depleted channel region which extends at least par-tially from a drain toward a source.  Minority carrier injection efficiency control means and transportation efficiency control means are also included.  The character of the region extending between the emissive junction at the source and the drain is carefully controlled so that the product, of the ionization current multiplication factor M and an electron-hole recombination probability factor .alpha. is less than unity.  Within limits, any specifically desired avalanche voltage can be created by controlling the characteristics of the transistor structure.  This voltage may then be varied bidirectionally by magnetic fields to form a new class of magnetic sensors.
