Title: Relief valve
IPC: G05D16/10
Filed: 1954-05-03
Abstract: 746,441. Fluid-pressure servomotor-control systems. DROITCOUR, H. A., and DROITCOUR; J. M. May 3, 1954, No. 12793/54. Class 135. A relief valve comprises a main valve plug 31 controlling a conduit between an inlet port 12 and an outlet port 13 and connected to a pressure-responsive member 32 movable in response to the difference between inlet port pressure in a chamber 35 having a restricted connection 65 with the inlet port 12 and a control port 37 for venting the chamber, the port 37 being closed against the pressure within the chamber 35 by a pilot valve plug 40 mechanically connected to a control member 57 responsive to the inlet port pressure and blocking a second conduit between the inlet port and the outlet port, the control member 57 being loaded by a spring 49. In Fig. 1 the spring acts through a pivoted member 54, which engages both the plug 40 and the control member 57. The working parts of the valve are all assembled in a unit 15 removably mounted in a bore 11 of a housing 10. The unit 15 is sealed by O- section rings 16, 17, and is held against rotation by a screw 19. The pressure-responsive member is formed as a grooved piston 32 integral with the plug 31 and slides in a bore 20 open to the inlet by a port 34. The piston may have a fit which allows some leakage of the inlet fluid into the chamber 35 or a restricted passage 65 may be provided in the piston. The plug and piston unit 31, 32 is pressed by a spring 36 against a seat formed on a block 23. The block 23 rests on a screwed plug 21 and has a bore 24 which connects by channels 25, 27 with the exhaust port 13. The pilot valve plug 40 is guided by a coil of wire 42 and co-operates with a seat 39. The upper end of the plug 40 engages a recess in the member 54 which is pivoted at 55 in a slot 44. The control member 57 is formed as a piston and has an 0-section packing 62 and a projection 58 to engage a recess in the lever member 54. The loading spring 49 is adjusted by a screw 50 carrying a lock-nut 66 and engaging a slidable block 46 above the spring 49. The inlet pressure has access to the piston 57 through channels 64, 63, which with the inlet port are sealed by a ring 18. In a modification, the pistons 32, 57 are replaced by bellows and the pilot bellows operates on a yoke carrying the pilot valve.

Abstract: 787,990. Steam separators. STEELS ENGINEERING INSTALLATIONS, Ltd. April 1, 1955 [May 5, 1954], No. 13112/54. Class 123(3) [Also in Group XVIII] A steam separator comprises a casing 1 having inlet and outlet connections 3, 4 and a removable cover 8. Within the casing is disposed a stack of plates of the form shown in Figs. 3 and 5, each plate 16 having corner lugs 18 whereby it is held spaced from the adjacent plates and slots 17 cut at an angle of approximately 45 degrees. The plates are arranged with the slots either in the vertical or horizontal direction and alternated so that the steam follows a side-to-side or up and down sinuous path through the separator. Entrained water collects on the plates and drains into a well 12 whence it is run off through an outlet 13. The end plates of the stack where, owing to its higher velocity, the erosive effect of the steam is greatest, are made of cast steel. The intermediate plates are made of zinc to provide cathodic protection against corrosion of the separator and pipe system in which it is connected.

Title: Improvements in or relating to television or like systems
IPC: H01J31/64
Filed: 1950-05-26
Abstract: 667,928. Cathode-ray tubes. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. May 26, 1950 [May 30, 1949], No. 13265/50. Class 39 (i). [Also in Group XL (b)] Apparatus for transforming a television image having a given number of lines n1, into an image having a different number of lines n2, the frequency of repetition of the images and their synchronization being unchanged in the transformed image, comprises a cathode-ray storage tube 1 in which the target is carried on a drum 11 rotating uniformly about axis 12. A first electron gun 2 modulated by the original image signal from analyser 10 scans the drum transversely at frequency n1 to store images whilst a second gun 3 operating with a constant intensity beam scans the drum transversely a frequency n2 to derive output signals. To effect interlacing, plates 4 and 5 fed in opposite phase by square-wave generator 7 deflects the two beams through the height h of an image during each frame fly-back. The drum has a metallized surface upon which is deposited a thin insulating layer of magnesia, alumina, potassium or sodium chloride, the images being stored and analysed by the release of secondary electrons under the impact of the scanning beams. The drum surface is curved transversely to compensate for cushion distortion. A polyphase motor, Fig. 2 (not shown), the rotor of which is located within the evacuated envelope, rotates the drum. The drum may be replaced by a disc on which the recording and analysing is effected in separate zones. A source 13 of slow electrons shifts the datum potential of the storage surface negative to increase the level of signal stored on the target. Screens may be arranged to mask intermediate storage surfaces not occupied by the scanning beams. In an alternative arrangement, Fig. 2 (not shown), the recording beam operates at a constant intensity and the video signals are applied to electrodes mounted adjacent the drum surface. Similar electrodes are provided in association with the analysing beam.

Title: Latched memory systems
IPC: G11C7/00
Filed: 1977-03-30
Abstract: 1523580 Latched memories HONEYWELL INFORMATION SYSTEMS Inc 30 March 1977 13379/77 Heading G4C A power strobe unit PS1 (Fig. 3) connected between the output of a latched memory array and a data bus is provided with power by a generator PSG1 when a timing signal is fed to the memory array. As described latched and unlatched memory arrays LMA1, LMA2; UMA1, UMA2 may be connected via a strobe unit and directly respectively to the same data bus. An array decoder activates either timing circuit 11 or 12 in response to an applied address signal to access either the latched arrays or the unlatched arrays. When a latched array is addressed the timing circuit 11 generates (1) row address signals RAS1, RAS2 and (2) after a delay determined by unit 18 column address signal CAS. Multiplexer 22 or 23 receiving the address signals accesses the selected array to read out via unit PS1, enabled when the row address signals from the timing circuit trigger generator PSG1 the address bit to data latch DL. When the unit PS1 is not enabled it presents a high impedance at its output. When an unlatched array is selected an associated internal clock driver 13, 14 causes the read out of the selected bit.

Abstract: 1520529 Funding postage meters PITNEY BOWES Inc 2 April 1976 [16 April 1975] 13473/76 Addition to 1492704 Heading B6C A computerized postage meter is funded from a remote computer, the remote computer producing a coded information on receipt of funding requirements and passing this to the meter user who inputs this to the meter, the postage meter program processing this coded information to add funds to the funding register. The remote computer may operate upon the account number of the user and/or the number of the meter and the amount of funding required to produce a coded number using one or more numbers held in store. This coded number is then passed to the user. The postage meter itself produces the same coded number in the same way by means of its postage meter programme. When the user inputs the coded number from the remote computer, the meter compares the coded number generated internally with the coded number supplied from the remote computer, and, only if the two are in agreement, does the meter add the requested funds to its register. The remote computer debits the amount of funds added to the meter account. A number of meters may be associated with a single remote computer.
