Abstract: A solenoid-operated pilot valve of the diaphragm type which includes an assembly for controlling the flow of liquid through the valve. The valve has particular although not exclusive utility for irrigation purposes. The valve includes a diaphragm chamber into which fluid is introduced to establish a fluid pressure which normally forces a diaphragm against an annular seat in the valve to assist a spring in maintaining the valve in a closed condition. A stationary bleed tube is provided which extends through the diaphragm into the diaphragm chamber. A solenoid is mounted on the cap of the valve, and the plunger of the solenoid normally closes off the upper end of the bleed tube. However, when the solenoid is energized, the plunger is withdrawn and the bleed tube opens and drains the diaphragm chamber sufficiently to reduce the pressure therein to a point at which the diaphragm is forced off its seat by upstream fluid pressure, and the valve is opened. A flow adjustment mechanism is mounted in the cap which includes an axially movable gear nut functioning as an adjustable stop for the diaphragm to control the flow of liquid through the valve.

IPC: H04L27/38

Abstract: A bandwith reduction technique is disclosed for use in digital systems wherein a pair of data signal elements modulate quadrature-related carriers. This modulation, re ferred to as quadrature amplitude modulation (QAM), phase shift keying (PSK) or amplitude and phase shift keying (APSK), generates a double-sideband signal which is transmitted in a variety of communications systems. In accordance with the present invention, the above-described double-sideband signal is filtered (103) to form either a single sideband or vestigial sideband signal prior to transmission. While this use of a vestigial or single-sideband signal, in lieu of a double-sideband signal, permits the transmission of more information in a given frequency interval, the filtering process contaminates the data signal elements. To recover the data signal elements at the receiver, a pair of received signal elements (110, 111) is formed by extracting the carrier signals. One of these received signal elements is then altered (118) at selected times to recover an associated one of the data signal elements (150) at each selected time. Finally, this associated data signal element at certain ones of the selected times is combined (119) with the other one of the received signal elements at an associated time to form the remaining - data signal element (151).

Abstract: Air conveying apparatus comprises a nesting table (10) which receives cylindrical articles (24)  en masse  from a mass air conveyor (12) at an upstream end and discharges the articles (24) onto a deadplate (28) in three rows of contiguous equilateral configuration. In one embodiment, a high air pressure zone is provided along the nesting table by means of a cover (40) extending from one side across the table to a line spaced at least one container diameter from the opposite side so that the containers entering the nesting table (10) form two longitudinal rows on opposite sides and fill in between with a third row which nests with the row of containers which is not under the cover. 
     A kicker plate (46) is provided downstream of the cover (40) to move the three formed rows of articles into nesting contiguous equilateral configuration for movement onto a deadplate. 
     In a second embodiment, the cover (56) is spaced at least two article diameters from the opposite edge and side guides converge the three rows of containers. 
     A third embodiment is like the second but has a second cover (72) extending from the opposite edge to a line   spaced from the first cover to form a slot (74) for escape of pressure air. 
     A fourth embodiment has a cover (82) extending across the entire table with converging downstream edges (86,88) which come to a point. A row of articles is formed along each edge and a third row beyond the pointed end.

Abstract: A masking member for use in masking holes during surface treatment consists of an inserting part (110), and a flange (120), formed at the base of the inserting part (110) wherein the inserting part (110) has a shape which is adapted partially to contact the inner wall of a hole into which the inserting part (110) is inserted. When the masking member is used, the inserting part (110) of the masking member is inserted into a hole of an article and the flange of the masking member covers the surroundings of the hole. Thus the inside and the surroundings of the hole are protected from a surface treatment and the removing of the masking member after the surface treatment from the hole may be very smooth since the inserting part of the masking member has a shape which partially contacts the inner wall of the hole.
