Patent GB-1002013-A (GB)
Title: Improvements in or relating to travelling wave tubes
IPC: H01J23/09
Filed: 1963-10-24
Abstract: 1,002,013. Travelling-wave tubes. SIEMENS & HALSKE A.G. Oct. 24, 1963 [Oct. 25, 1962], No. 41982/63. Heading H1D. In a travelling wave tube having a helical delay line 1, an outer conductor 2 and an electron beam 3 guided by the electrostatic field between the delay line and the outer conductor in a helical path along the delay line, the angular velocity 5 of the electrons at the start of the delay line is less than the phase angular velocity 6 of the electromagnetic wave on the delay line to such a degree that synchronism between the electron beam and the wave occurs at a position between the start and the end of the delay line. Due to the initial interaction between the beam and the wave, the linear velocity of the electrons decrease and the beam takes up an equilibrium path of smaller diameter than its original path; the angular velocity of the electrons, however, increases. The angular velocity of the electrons at the start of the delay line is between 80 and 95%, e.g. 90% of the phase angular velocity of the wave on the delay line. The delay line is either an interdigitated line or a helix, both following a generally helical path. Specification 987,238 is referred to.

Title: Positive displacement pumps
IPC: F04C14/14
Filed: 1972-09-25
Abstract: 1389887 Rotary positive-displacement pumps TRW Inc 25 Sept 1972 [24 Nov 1971] 44226/72 Heading F1F A pump of the sliding-rocking vane type comprises a valve plate 50 for varying the discharge of the pump and also for reversing pump flow. Plate 50 has kidney ports 118, 119 formed by channels in one side 114 of the plate. These ports 118, 119 communicate via holes 122, 121 with an outlet port 120 formed in the other surface 116 of plate 50. By-pass notches 112, 113 are formed in the plate and are cut off from ports 118 to 122. Port 112 opens into an enlarged recess 117 on side 116 of plate 50. Plate 50 is rotatably mounted on a ring 48 attached to housing 16 and through which extends shaft 32 for the rotor 38. Rotation of plate 50 is effected by an adjusting arm 54 fixed to shaft 56 and having a finger 53 which engages a slot 52 in a boss 51 on plate 50. Between a cam ring 42 for the pumping elements 40 and the plate 50 is held a port plate 47 having two sets of holes 90-95 and 100-105 which communicate with similar sets 70-75 and 80-85 in cam ring 42 which form outlet zones for the pumping chambers 44, 43 in the two-lobed ring. Fluid is drawn in from chamber P to the pumping chambers via notches 77, 87 in ring 42 and is discharged through openings 70-75 and 80-85 and then to openings 90-95, 100-105 in port plate 47. When the plate is in its "neutral" position with the slot 52 vertically above the drive shaft axis, ports 90-95, 100-105 communicate with the by-pass notches 113, 112 of plate 50 and these return the fluid to the chamber P and there is thus a zero discharge from the pump. When the plate 50 is rotated to the "forward" position port 119, on the side 114 adjacent plate 47, overlaps some or all of ports 70-75 while port 118, also on face 114, overlaps some or all of ports 80-85. Fluid is transferred from ports 119, 118 via openings 121, 122 to the recess 120 on the other side 116 of plate 50 which abuts end 18 of housing 16. There are two kidneyshaped ports 63b, 64b in housing end 18 which lead to ports 63 64 and tilting to the "forward" position of plate 50 will have brought outlet recess 120 into communication with port 63b and bypass recess 117 into communication with port 64b. Thus fluid will be discharged from recess 120 to port 63 and be returned from port 64 via recess 117 to chamber P. The fluid in those ports 70-75, 80-85 not overlapped by ports 118, 119 will be by-passed via notches 112, 113 to chamber P. If valve plate 50 is rotated in the opposite direction to the "reverse" position, then it can be seen that fluid flow will be reversed i.e. discharge from port 64 and ingress of fluid to port 63.
