Abstract: A system that is to be placed on a wafer is partitioned into reasonably large functions, each provided with a set of I/O and power pads. The wafer design is called "design A". A second wafer design (design B) that is the mirror image of design A is also constructed. Wafers of designs A and B are tested and divided into two groups: group I wafers have relatively few functions that are inoperative; group II wafers have relatively few functions that are operative. Inoperative functions are removed from group I wafers and discarded; good functions are removed from group II wafers and retained. A given function on wafer A is the mirror image of the same function on wafer B. Therefore, a given function from a group II wafer A (or B) can be inverted and attached to a group I wafer B (or A) that has had the corresponding function removed from it. The I/O and power pads of the function removed from the group II wafer are joined to the I/O and power pads remaining on the group I wafer.

Abstract: A mass-imbalance oscillation generator comprises a trough in which a rolling element, such as a cylindrical roller or ball, is permitted to move between one side and another between two stable positions in response to centrifugal force generated by rotation of the shaft carrying the trough. The rolling mass can assume either of two stable positions depending upon the speed of the shaft, one of the positions corresponding to a higher potential energy of the mass than the other position to enable shifting movement of the mass.

Abstract: 1500891 Signalling over power lines GENERAL ELECTRIC CO Ltd 16 July 1975 [18 July 1974] 31964/74 Heading H4R Signalling over power lines is effected by reducing the amplitude of selected cycles of the power waveform, throughout the same small portion of the cycle period including a voltage zero by drawing current from the system only throughout that portion. As described, the amplitude is reduced for a period not greater than one tenth of one cycle of the power supply at a negative-topositive going zero-crossing by firing a thyristor connected across the power supply. At the transmitter Fig. 5, the mains voltage across LN is differentiated and phase-shifted by 90 degrees in R21, C21 then squared I to produce positive pulses corresponding to positive mains half-cycles. The trailing edges of the pulses trigger a timer 2 producing further pulses of such duration that their trailing edges define the angle at which the thyristor is to be fired. The firing pulses are generated at 3 and gated to the firing transformer T1 when the code generator is operative and detectors 7, 8 confirm that the zero-crossing is in the proper direction and the waveform amplitude is below a predetermined value. The information code is such as to modify the first cycle for START, three selected odd cycles out of cycles 3 to 23 for ADDRESS and an odd cycle out of cycles 25 to 31 for DATA. At the receiver Fig. 7, the mains voltage is applied across R9, R10 to begin charging capacitor C4 when TR4 is turned off at each negative-topositive zero crossing. Diode D4 prevents overcharging. Capacitor C5 charges to the peak value held in C4 via D5 and TR5. Resistor R13 acts as a slow bleed to C5 and any charging current from C4 to C5 is monitored via TR5 and TR6 to provide an output G which lacks a pulse at the instant that the power waveform is modified. To control TR4, transistor TRI is off during negative half-cycles across LN and therefore produces a pulse train B whose amplitude equals the bias voltage + V. The trailing edges occur at negative-to-positive zero crossings and cause TR2 to turn off, allowing C2 to charge until TR2 turns on again. This therefore produces control pulses for driver TR3 to control TR4.

Abstract: A method of joining together by heat welding two tubular elements of a meltable thermoplastic material. The elements are arranged so that one tubular element receives one end of the other element in a telescoping manner to form an annular space between the two elements. A welding sleeve of a meltable thermoplastic material is positioned in the annular space between the two tubular elements. Heating elements are also arranged in the annular space for heating and welding the welding sleeve to the surfaces of the two tubular elements. Additionally, a ring-shaped body which becomes enlarged when heat is applied thereto is positioned in the annular space between the two tubular elements and the heating elements are arranged on the outer surface of the ring-shaped body. The two tubular elements and the welding sleeve are pressed together by the force exerted by the ring-shaped body whose material shape is changed from a state in which it is originally dimensionally stable in heat to a state in which it is dimensionally unstable in heat.

Abstract: An interchangeable nozzle for on irrigation sprinkler includes a tubular housing 36 mounted at the discharge end 18 of the sprinkler, and arranged to receive any of a plurality of insert members 34 which may be selected for controlling the water flow rate, the distribution or range of throw. The diameter 46 of the insert 34 at its inlet end corresponds to that of the discharge end 18, the outlet 48 being of reduced diameter. The insert is held in position by a threaded collar 38. In part-circle applications on a reaction drive type sprinkler [Fig. 9], the inserts are arranged to limit movement of the reverse drive arm (80) into the stream of water ejected from the nozzle by an amount dependent upon the nozzle size, thereby resulting in substantially the same reversing force regardless of nozzle size. <IMAGE>

Abstract: A digital filter arrangement is provided which both demodulates and filters the color mixture signals in a television receiver. Samples of a digital chrominance signal are clocked into first and second registers such that the first register is loaded with samples of a first color mixture signal and the second register contains samples of a second color mixture signal. Output taps are connected between various ones of the stages of the first and second registers and weighting function circuits. The weighting function circuits associated with each register are in turn coupled to respective ladder networks of adders, which combine the weighted signals samples so as to exhibit, at an output stage adder, a lowpass response characteristic which is appropriate for the respective color mixture signal. The two digital registers are aligned in time in accordance with their respective peak impulse response characteristic to product filtered color mixture signals in a proper timed relationship.

Abstract: The invention relates to a collapsible or foldable, wheeled good container provided with a bottom (9) and four side-walls (11, 12; 14, 15; 18, 19). The side-walls of such goods containers are normally arranged to be folded down in sequence, over the container bottom. This enables collapsed containers to be piled in stacks, so as to save space when returning empty containers. Stacking of such containers, however, is difficult to carry out and requires the lifting work of two persons. In accordance with the invention, the handling of collapsed empty goods containers has been made easier, by giving the bottom of the container the form of a four-sided right-angled frame structure (1-6) on which there is mounted a bottom plate (9), wherewith two mutually opposing frame parts (3, 4; 5, 6) are arranged to be folded inwardly and the bottom plate to be swung or folded upwards. The two remaining frame parts (1, 2), to which free-standing sides (11, 12) of the container are attached and which suitably carry wheels (13), move close together when the container is folded or collapsed, to be separated solely by the inwardly directed frame parts (3, 4; 5, 6). Subsequent to being collapsed, the goods container takes up but little space and can be readily pushed away, to be stacked with other collapsed containers in a small space.

Abstract: Method of effecting zoning in wood with the aid of fungus cultures. The wood is pretreated by sterilizing it, setting a suitable moisture content and impregnating it. Impregnation with nutrients ensures that the fungi are sustained by the nutrients added and not by the wood. Special patterns can be achieved by using inhibitors. Pretreated wood is inoculated with one or more fungus cultures and stacked in sandwich fashion. An interlayer is inserted into the inoculated sandwich to produce the desired zoning pattern. Incubation is performed with controlled moisture contents and moisture gradients in the wood, as well as the composition of the gas phase, and may be carried out as a two-step process. The method is performed entirely or partially in a closed system.
