Abstract: LIQUID CRYSTAL DISPLAY DEVICE          Abstract of the Disclosure A matrix array of liquid crystal cells is defined by overlapping pluralities of row and column conductors confining a layer of liquid crystal material.  Each row conductor is connected through a bilateral threshold switch to one side of a source of periodic alternating polarity sustain signals, and the column conductors are sequentially connected to the other side of the source.  When an initial charge is deposited on selected ones of the capacitors forming the liquid crystal cells, the series combination of the resulting stored voltage and the sustain signals is sufficient to exceed the threshold of the bilateral switch, thereby connecting the previously selected cells to the source of alternating source on a column-by-column basis so as to recharge the previously selected cells.  Since charged cells exhibit differing electro-optic properties from uncharged cells, a graphical image may be generated and stored without the need for information-bearing refresh signals.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to a plant for blasting of ob-jects such as rock, concrete, and the like, where the objects are provided with a number of bore holes containing fuses with blasting caps and explosives such as dynamite, water-gelatine explosives, and the like.  The fuse is a low-energy fuse suit-ably consisting of a tube which is coated inside by an explosive or another reactive substance, and the fuse works together with coupling blocks and start-blasting caps.  According to the in-vention, each bore hole is provided with a fuse, which in one end is fitted with a blasting cap and in the other end is free, Outside of the bore holes, a number of coupling fuses are ar-ranged, and are fitted either in one end or in both ends with a start-blasting cap with or without time-delay arranged in a coupling unit, for example, in the form of a coupling block made e.g. of plastic.  The unit can take one or more fuses in order to transfer to these the initiation when the start-blast-ing cap is initiated.  The coupling units are coupled together in the free ends of the fuses in the bore holes and with the free ends to coupling fuses, and a coupling fuse with a free end has this connected to an initiator.  This produces an initiating wave through the connected fuse.

Abstract: WHEEL LOCK CONTROL SYSTEM FAILURE AND DISABLING CIRCUIT     Abstract of the Disclosure:          A wheel lock control system for a vehicle is de-scribed that is responsive to wheel speed to provide a brake release signal when the wheel speed signal characteristics represent an incipient wheel lock condition.  The braking forces on the vehicle wheels are relieved by the wheel lock control system for the duration of the brake release signal.    A monitoring circuit monitors selected system parameters and provides a fault signal while the parameters represent a fault condition.  A logic circuit is responsive to the fault signal and the brake release signal to provide an inhibit signal which is initiated solely by the fault signal and terminated only when both the fault and the brake release signals are terminated so that the inhibit signal exists only for the dura-tion of a temporary fault occurring during time periods other than during a brake release signal and exists for the duration of the longer one of the fault signal or a brake release sig-nal if the fault signal coexists at least momentarily with the brake release signal.  The system is inhibited from releasing the vehicle wheel brakes during the period of the inhibit signal.

Abstract: NOISE BLANKER CIRCUIT           ABSTRACT      A noise blanker circuit usable in a radio receiver is disclosed.  Noise pulses in demodulated received signals are detected by a noise detector amplifier.  These detected noise pulses are then processed by a control means which develops control signals that selectively control a blanking gate which is followed by a holding capacitor.  The gate and holding capacitor combine to blank out noise in the de-modulated signals in response to the production of the control signals.  The control means includes an amplifier with an AC negative feedback loop that includes a varactor diode.  A rectifier diode is used to develop a DC voltage proportional to the occurrence rate of noise pulses and this DC voltage biases the varactor diode such that noise blanking only occurs when the noise present on the received signal is below a predetermined rate of occurrence.
