Abstract: Apparatus for continuously and rapidly forming trays of highly uniform elastomeric soil plugs comprises means for continuously mixing a water-containing soil slurry with a water-reactive pre-polymer compound, means for supplying the soil slurry and the pre-polymer compound to the mixing means at respective controlled rates, and means for delivering the mixed soil slurry and pre-polymer compound to a dispensing station for dispensing into mold receptacles; the receptacles are disposed in a closed path and carried by transport means seriatim past the dispensing station. Releasable bias means biases a tray mpld member against a base mold member within each receptacle so as to extrude soil-pre-polymer mixture into plug-molding cavities of the tray mold member. The bias means is released after the plugs within the tray mold member have cured. The operation of the apparatus coordinates the various steps in the plug-molding process with stages of the chemical reaction between the water and pre-polymer compound to form highly uniform plugs at the maximum rate allowable by the chemical reaction.

Abstract: A current-drive circuit is provided to drive each of forty electrodes (41). When selected, the circuit forces line (27) to a level of drive voltage (Vdr) minus a current-level reference voltage. A constant current is produced across resistor (25). Line (27) is connected through resistor (29a) to line (27a), which is the same point in the current-drive circuit of the adjoining electrode (41 a) on one side of electrode (41). Line (27) is similarly connected through resistor (29b) to line (27b), which is the same point in the current-drive circuit of the adjoining electrode (41b) on the opposite side of electrode (41). Selection of the drive circuit also connects line (27) to the associated electrode (41). An unselected drive circuit for an adjoining electrode, such as the one connected to drive electrode (41a), has line (27a) floating to the level dictated by Vdr through its resistor (25a), while its electrode (41) is disconnected. Current from the unselected circuit through resistor (29a) adds to the current in electrode (41), thereby eliminating lightened-edge printing from current spreading.

Abstract: A hierarchical memory system for use with a high speed data processor characterized by having separate dedicated cache memories for storing data and instructions and further characterized by each cache having a unique cache directory containing a plurality of control bits for assisting line replacement with the individual cache memories and for eliminating many accesses to main memory and to insure that unnecessary or incorrect data is never stored back into said main memory. 
     The present cache architecture and control features render broadcasting between the data cache and instruction cache unnecessary. Modification of the instruction cache is not permitted. Accordingly, control bits indicating a modification in the cache directory for the instruction cache are not necessary and similarly it is never necessary to store instruction cache lines back into main memory since their modification is not permitted. 
     The cache architecture and controls permit normal instruction and data cache fetches and data cache stores. Additionally, special instructions are provided for setting the special control bits provided in both the instruction and data cache directories, independently of actual memory accessing OPS by the CPU and for storing and loading cache lines independently of memory OPS by the CPU.

Abstract: The invention is concerned with the problem of how best to nfect roots of a plant with the beneficial mycorrhizal fungus. Merely mixing the inoculum of the fungus with soil or other growth medium is time-consuming and not very effective. The invention lies in the idea of positioning across the path of growth of the roots a carrier material, carrying the inoculum. The roots are then allowed to contact and penetrate the carrier material, so that they pick up the inoculum and become infected. The carrier material is integral and self-supporting. Preferably it is a sheet of cellulosic fibres coated with a layer containing the inoculum, which can also contain celluosic fibres. Preferably peat-inoculum is used. The invention is useful in improving the growth of plants, particularly those grown in containers.

Abstract: A typewriter of the kind having a rotatable type carrier (30) comprising flexible radial fingers (34) each having a printing element (38) at its duter end, drive means for positioning the type carrier (30) on depression of a character key so that the corresponding printing element is at a printing position, and a hammer (55) operable to strike the printing element at the printing position. The drive means for the type carrier (30) comprises a mechanical coupling between the type carrier (30) and each character key (54) of the typewriter operable on depression of the key to rotate the type carrier (30) from an initial ppsition, an array of stops (60), each corresponding to one of the printing elements (38) and each coupled to the corresponding key (54) so that on depression of the key the stop (60) is moved from a retracted position, in which the stop (60) is clear of the type carrier (30) during its rotation, to a projected position in which the stop (60) is in the path of an abutment (41 or 43) on the type carrier (30), engagement of the abutment with the stop causing the type carrier (30) to be arrested with the printing element (38) corresponding to the key (54) at the printing position, the coupling between each key (54) and the type carrier (30) being resilient to enable the key to continue its travel after engagement of the abutment (41 or 43) with the stop (60). The use of mechanical couplings to rotate the type carrier and stop it at the correct position avoids the need for an electric drive motor and complex control arrangements. The hammer may also be coupled to the keys, so that the typewriter can be made purely mechanical.

Abstract: The invention relates to an electrical insulation composition of a polyolefin, which can be used for medium and high voltage from about 10 kV and which resists effectively and permanently the formation of so-called water trees. The insulative polyolefin contains an inorganic oxide additive, in homogeneous distribution therewith, at a concentration of 0.05 to 10% by weight, relative to the total weight of the composition. The additive is absorption-active for heavy metal ions and/or binds heavy metal ions in an ion exchange, with a particle size of up to 50 um or an agglomerate size of up to 100 um. It can be silica, alumina, hydrated alumina or an aluminum silicate. The electrical insulation according to the invention is particularly well-suited for use in cables and wires.

Abstract: In the handle for hand tools, in particular for drills, hammer drills or drill hammers, the attachment to the spindle collar of the hand tool takes place via a strap retainer, which is tightened by means of a hammer screw and an insert nut injection-moulded in the auxiliary handle. Tightening is effected by rotating the handle and thus by turning the insert nut. The strap retainer is contained in an attachment head, which has a shoulder which serves for holding and guiding a depth stop, which has a side face which is corrugated, for example transversely to the longitudinal extension of the depth stop. The correspondingly corrugated pressure surface of a pressure element acts on this corrugated side face. The contact force is produced by a spring. The depth stop can be moved simply by moving the pressure surface of the pressure element away from the corrugated side face of the depth stop. This is achieved by finger pressure on the pressure element. <IMAGE>

Abstract: A fiber optic rotation sensor, employing the Sagnac effect comprising all fiber optic components positioned along a continuous, uninterrupted strand of fiber optic material. The rotation sensor includes a detection system utilizing a modulator (38) or modulators (38, 138) for phase modulating at first and second harmonic frequencies light waves which counter-propagate through a loop (14) formed in the fiber optic strand. Each modulator (38,138) is operated at a specific frequency to eliminate amplitude modulation in the detected optical output signal. 
     A phase sensitive detector (30, 46) generates a feedback error signal proportional to the magnitude of the first harmonic in the output optical signal. The feedback error signal controls a modulator (130) which controls the amplitude of the second harmonic driving signal forthe second harmonic phase modulator (138) such that the first harmonic component in the output signal from the rotation sensor is cancelled or held within a small range of amplitudes.
