Abstract: Patent Case No. I1104361-U.S.                APPLICATION OF                ROBERT SCHMITZ                  ABSTRACT A membrane keyboard blockout apparatus for a keyboard having an array of a plurality of flexible key members in respective ones of a plurality of apertures arranged in a grid forming the keyboard includes a cover plate dimensioned to span a flexible key member and to provide a tight fit within an aperture defining a key member. The cover plate has a thickness providing a substantially inflexible configuration in response to normal operator manipulation and a plurality of corner support pedestals contacting respective corners of the flexible key member when the cover plate is inserted in a key member aperture.  Thus, the pedestals provide a support between the cover plate and the flexible key member at the edges of the key member to preclude, in combination with the inflexible structural characteristic of the cover, an actuation of the flexible key member under the cover.

Abstract: FLOCKED YARN AND METHOD FOR MANUFACTURING IT      ABSTRACT OF THE DISCLOSURE           A flocked yarn comprises a core yarn with a total denier of 140-1260, an adhesive applied onto the core yarn at an amount within predetermined range and flock fibers with a cut length of 0.5-3.0 mm which are flocked at a flocking density of not less than 30,000/cm2.  The flocked yarn can be obtained by a method wherein for application of flock fibers onto an adhesive layer applied to the core yarn an electrostatic field in which an attractive force operates and an electrostatic field in which a repulsive force operates are applied either alternately by changing the polarity of one of a single pair of electrodes or, in a continuous process, sequentially by arranging two kinds of electrostatic fields.  The flocked yarn thus obtained can have a good touch, a high flocking density and a high abrasion resistance.

Granted: 1992-08-18
Abstract: HOMODYNE-TYPE SPREAD SPECTRUM TRANSMITTER/RECEIVER            Abstract The present invention relates to a homodyne-type spread spectrum transmitter and an associated remote spread spectrum receiver which communicate with each other by the transmission of both (1) a spread spectrum Pseudo Noise Code (PNC) sequence signal, and (2) a combined PNC sequence plus the data information (PNC+data) signal. The two signals can be transmitted concurrently using either different frequency bands or on a quadrature carrier; or the two signals can be transmitted with a time offset between signals. At the receiver the PNC and the PN+data signals are separately recovered for the case of the concurrent transmission techniques, anddirectly mixed to despread the received signal and recover the data signal at baseband. For the time offset technique, the delay provided in one of the time offset signals is again introduced to the previously delayed signal, and the delayed and undelayed signal portions of the received combined signal are directly mixed and then low pass filtered to recover the data signal. Such techniques eliminate the necessity for providing PNC acquisition and tracking circuits in associated spread spectrum transmitter and receiver combinations.

Abstract: A switching system for switching synchronous and/or synchronous data blocks between incoming and outgoing multiplexes. The asynchronous blocks are sporadically carried in the multiplexes. The cost of the system is reduced owing to the use of a single buffer memory whose cells memorize indifferently synchronous and asynchronous blocks. The number of cells is lower than the product of the number of incoming or outgoing multiplexes and the number of blocks per frame in the multiplexes. A buffer memory managing and write addressing circuit derives and memorizes the occupied or free condition of each of the buffer memory cells thereby permanently selecting the address of one of free buffer cells in which a data block is to be written. The occupied condition of a cell is signalled responsive to the write of an incoming data block into this cell, and the free condition of the cell is signalled responsive to the last read of the written block. A written block may be read several times when it should be transmitted onto several addressee outgoing multiplexes.

Abstract: A main valve (1) is connected into a pressurized water pipe for an irrigation installation and has a valve body (4) formed as a differential piston and with a through bore (5), said body being operated in both directions by means of the water pressure, the piston (4) in one end position closing the water pipe and in its other end position keeping it open. The piston (4) is guided to said end positions by means of a control valve (7) arranged to open or close a duct (6) starting from the major cylinder bore, thereby to cause the water present to actuate the piston (4). The control valve (7) is in turn controlled by rainfall onto, and evaporation from an upwardly open bowl (8), and a drop means (9) active during irrigation. The bowl (8) is part of a tipping means with two tipped end positions, controlled by the quantity of water in the bowl (8). To achieve operation of the main valve (1) such that irrigation substantially takes place at night, and that the length of time between irrigation can be varied, the tipping means is supplemented by a closed air chamber (15) on the other side of the pivoting shaft (35), said chamber and bowl (8) having a common flat bottom (16) and mutual communication via a slit (17) at the bottom. By the volume change in the air enclosed in the air chamber (15), caused by the temperature difference between night and day, the quantity of water contained in the open bowl (8) and in the chamber (15) is displaced at night such that the tipping means tips over into a position opening the main valve (1).
