Patent GB-1443361-A (GB)
Title: Lsi chip construction
IPC: H01L21/822
Filed: 1973-06-25
Abstract: 1443361 Integrated circuits AMDAHL CORP 25 June 1973 [10 July 1972] 29966/73 Heading H1K The component circuits of an LSI chip are arranged in a two-dimensional array of circuit groups (termed "macros"), each macro containing a plurality of circuits and being located in a discrete chip area spaced apart in both directions of the array from adjacent macros, there being a (preferably two-level) metallization pattern including portions for interconnecting the macros over lying the spaces therebetween. In the embodiment voltage distribution buses and ground distribution buses are provided respectively in first and second metallization levels, the two sets of buses being mutually orthogonal with the former located over the spaces between adjacent columns of macros and the latter located over the centre-lines of corresponding rows of macros. Since the second metallization level may be substantially thicker than the first the voltage drop on the ground bus system is less than on the voltage bus system. Preferably the voltage drop on the ground bus system "tracks" that on the voltage bus system, and also "tracks" with chip temperature. The component circuit (e.g. emitterfollowers) of each macro is preferably arranged symmetrically relative to orthogonal centre lines of the macro, with intra-macro connections located near the centre and intermacro connections located adjacent the periphery of the macro. The resistors have one end adjacent the centre and the other adjacent the periphery of the macro. Generally conventional processing steps for production of the LSI are described, involving successive use of a series of diffusion masks identical for all macros in a chip and for all chips in a wafer, different circuits being obtainable in different chips to be subsequently broken from the wafer by the use of different metallization and via hole masks

Filed: 1949-11-25
Abstract: 676,990. Potato &c. peelers. OSLIFF, G., and SAUNDERS, A. Nov. 27, 1950 [Nov. 25, 1949], No. 30230/49. Class 28 (ii). In a turning lathe type of potato peeler in which a peeling knife 48 follows the contour from one end to the other, of a potato &c. which is spiked on a hand rotated spindle 18, and in which the knife 48 is spring pressed against the potato surface and is also moved in a horizontal arc roughly corresponding with the potato contour, the arcuate travel of the knife, which is derived from the handle 20 through bevel gears 24, 28, is disconnected at the end of peeling by pulling out a knob 36 which pulls a worm 33 axially away from its driven worm quadrant 34 so that the radial arm 40 carrying the knife 48 can be rotated back by hand around its pivot shaft 35 to reset the knife position for the next potato to be peeled. Release of the knob 36 allows a spring 38 to slide the worm into reengagement with the worm quadrant 34. A spring 45, Fig. 3, allows the arm 42 carrying the knife to be rocked about 41 to allow room for impaling a fresh potato on the spike 21. The spike 21 is pointed and has strengthening flanges 22. The arm 42 which carries the knife 48 has a tail 47 to engage the arm 40 and so prevent the spring 45 from pressing the knife in too far and so prevent the knife from fouling the spike 21. The knife 48 is located above the plane of the spike 21. Fig. 6 shows the knife 48 with an upper curved guard 49 to limit the penetration of the knife. The peel passes between 48 and 49 through an exit 54.

Title: Ultrasonic pulse communication system
Inventor: ZENS RENE
IPC: B06B1/02
Filed: 1964-08-01
Abstract: 1,107,015. Ultrasonic signalling systems. VACUUM REFLEX Ltd. 27 July, 1965 [1 Aug., 1964], No. 30413/64. Heading G4F. [Also in Divisions G1 and H4] The temperatures at three points under water are measured electrically in sequence and the corresponding values are transmitted through the water to a receiver and indicator on ship or shore by modulating the repetition frequency of short bursts of ultrasonic energy. Transmitter.-A ceramic ultrasonic transducer S1, Fig. 1, is energized by a resonant circuit T1 which is shock-excited by a silicon controlled rectifier SCR1, the repetition frequency of the output pulses being controlled by a relaxation oscillator comprising a unijunction transistor U1, capacitor C3 and resistor R2. In operation, the resistor shown as R2 consists of five resistors switched into circuit sequentially. The first is a fixed value resistor to provide a synchronizing signal which is of higher frequency than the measurement signals. The next three are the temperature sensitive resistors for measuring, and the last is a fixed value resistor to provide a calibrating signal equivalent to a temperature of 20‹ C. In a modification, Fig. 4 (not shown), an auxiliary circuit is provided to render the silicon controlled rectifier SCR1 non-conductive more rapidly after triggering so as to raise the frequency of operation. Receiver.-Ultrasonic pulses received at 1, Fig. 2, are converted to electrical signals, amplified, demodulated from the ultrasonic carrier and converted at 4 to square waves having a constant (10 millisecond) duration and a repetition frequency equal to that of the relaxation oscillator U1 &c. at the transmitter. The temperature measurement signals are passed by gate 14 to a counter 16 which counts the number of pulses occurring during a fixed measuring period which is determined by a bistable circuit 13, thus providing an output signal proportional to pulse frequency, i.e. proportional to the temperature sensed at R2. The counter 16 may be replaced by a ramp voltage generator operative for the period between two successive signal pulses. The three temperature measurements and the 20‹ C. fixed calibrating signal are displayed in turn., the particular channel in use being shown by lamps L1 to L4 controlled by a distributer 10 which is stepped progressively by short transmissions of synchronizing signal between each temperature transmissions. This synchronizing signal, which is of a higher repetition frequency than the measurement signals is detected at 5 and causes a shift pulse to be sent to the distributer 10 and also provides a signal to reset the counter 16 to zero before each measurement. At the commencement of each complete cycle of readings, the synchronizing signal is transmitted for twice the normal length of time, a condition detected by a delay network 7 and gate 8 so as to provide a reset signal for the distributer 10.
