Abstract: 1450401 Valves ROBERT BOSCH GmbH 21 Sept 1973 [22 Sept 1972] 44409/73 Heading F2V In a pressure regulator having an input 16, a return 13 and a load port 24 the pressure in a chamber 8 which communicates with the load is kept constant by a diaphragm valve member 7 co-operating with a pair of valve seats 9, 10 connected respectively with the return and inlet ports, the diaphragm being loaded to the closed position of the inlet by a spring 22 and also by fluid pressure differential resulting from the difference in area of the seats 9, 10. The diaphragm bisects the chamber 8 and has apertures 7a to allow for fluid flow through it. An electromagnet having an armature 21 acting on the diaphragm may be energized to vary the desired pressure in chamber 8. Alternatively a second spring may be used; or a second electromagnet instead of spring 22. The diaphragm may be the armature. In a modification, Fig. 2 (not shown), the diaphragm valve member is replaced by an assembly comprising a ball (28) co-operating with the inlet valve seat (10) and a plate (29) co-operating with the return valve seat (9) the ball (28) being connected to the plate (29) through a plunger (26) and second ball (27). The return passage may incorporate a check valve (37).

Abstract: 1,221,054. Endless conveyers. A.M.F. Inc. 30 Sept., 1968 [29 Sept., 1967], No. 44464/67. Heading B8A. Two series of articles (not shown) are fed by respective roller conveyers 10, 12, each article being temporarily halted and released by gating fingers 22 and being conveyed onwards by respective endless conveyers 14, 16. The articles on the conveyer 14 are successively inverted by a system of rotary fingers 238 and then pass via a belt conveyer 18 to respective compartments of an endless flight-conveyer 34. The series of articles on the conveyer 16 are delayed in succession by a series of gating finger assemblies 26 and 28 in relation to the progress of the articles on the conveyer 14. The timing is such that a given article on the conveyer 16 is fed to a compartment of the conveyer 34 that has previously received an article from the conveyer 14 released by the fingers 22 at the same time as the release of the given article. A belt conveyer 20 similar to the conveyer 18, may be adjusted to an upwardly inclined position so that the given article is fed on to the top of the inverted article. The gating fingers 22 are normally held in raised position and are lowered after a predetermined time interval when articles obstruct a photo-electric gate 100. The inverter fingers 238 and the gating finger assemblies 26 and 28 are actuated by linkage driven by cams driven in synchronism with a main drive for the conveyers 10, 12, 14 and 16. Two further gating mechanisms 168 and 170 are driven by similar means. Adjustable article guides 156 and 158 are mounted on either side above each of the belt conveyers 18 and 20. The inclination of the latter may be adjusted by a screw 152 and slot 150 (Fig. 4).

Title: Improvements in or relating to apparatus for feeding outputs in phase quadrature
IPC: H01P5/12
Filed: 1962-12-03
Abstract: 981,643. Power distributing networks. SIEMENS & HALSKE A.G. Dec. 3, 1962 [Dee. 4, 1961], No. 45596/62. Heading H1W. [Also in Division H4] A number of loads, e.g. aerials, are fed in phase quadrature from a pair of inputs operating in antiphase. As shown, the antiphase inputs are provided by an unbalance-to-balance transformer 4 fed by a coaxial line 1, 2. Half the outputs of the balun are fed through paths of equal length (l 1  +#/ 4 ) to loads A 1 , A 2  which thus operate in antiphase. The other halves of the balun outputs are tapped at junctions V 1 , V 2  and fed to a third junction V 3  via two parallel paths 11, 12 and 23, 24 which are respectively one quarter-wavelength (#/4) shorter and one water-wavelength (#/4) longer than the equal paths to the loads A 1 , A 2 , the lengths all being measured from the balun output V, # being referred to the mean frequency of operation. At this frequency, waves arriving at junction V 3  combine in phase. At frequencies slightly removed from the mean frequency, the waves arriving at V 3  have antiphase components, but these components affect only the amplitude of the output from V 3 , this output remaining in phase quadrature relation with the outputs to loads A 1 , A 2  over a band of frequencies. By means of a reversal of connections, two loads A 3 , A 4  may be fed from junction V 3  in antiphase, the four loads A 1 . . . A 4  being then distributed in quadrature. In a modification (Fig. 5, not shown), a single load is attached to junction V 3  and the fourth output derived from two further parallel paths similar to the paths 11, 12 and 23, 24. These paths are tapped from the junctions between lines 13, 14 and 15, 16 and between lines 9, 10 and 17, 18. Uniform power distribution may be assured by connecting in the lines 7, 8 and 17, 18 quarter-wavelength slotted conductors 7, 17, Fig. 3, coupled to balun transformers 36, 39. The purpose of the latter is to couple reflected components to the dissipative loads 38, 41. A similar purpose may be served by modifying the balun 4 in the manner shown in Fig. 4. The characteristic impedances of the various lines are so chosen that they present matched loads to the junctions.

Each wedge 32 is provided in its radially inner and outer end faces with recesses which in the arrays form annular recesses, an elastic member such as an O-ring being received in each recess. Two adjustable clamping bands 54 are provided encircling the arrays 34, 36, the bands each having a releasable clamp to thereby relieve the tension in the band and the clamping effect of the wedges. The wedges 32 are each formed with a recess 38 in one face and a mating keyed surface 40 in the opposing face. In the assembled array, the ends of the knives are clamped between the recess 38 and keyed surface 40 of adjacent wedges. Means are preferably provided for moving one array of wedges axially away from the other array to place the clamped knives under tensile load. To vary the length of material cut, selected knives may be removed at regular or random spacings. To ease the flow of cut material into the interior of the rotary cutter head, the opposing surfaces 58, 60 of the spaced arrays 34, 36 diverge radially inwardly of the cutter.
