Patent GB-1059809-A (GB)
Title: Fluid pressure regulator
IPC: G05D7/01
Filed: 1965-12-15
Abstract: 1,059,809. Valves. GROVE VALVE & REGULATOR CO. Dec. 15, 1965 [Dec. 18, 1964], No. 53292/65. Heading F2V. The pressure regulating valve is closed by downstream pressure applied to one side of a diaphragm 52. The diaphragm is loaded by a constant pressure applied through a restriction 60. Downstream pressure is led to the diaphragm through a passage 66, 67, 68 from the throat of a flared outlet or Venturi 64. Thus the increase in pressure loss owing to increased flow is broadly compensated. In order to provide a more precise compensation, a second connection is made from the diaphragm through a restricted orifice (72), Fig. 3 (not shown), which is smaller than the passage 66, 67, 68, to a point downstream of the Venturi 64. Orifice (72) communicates on one side with an annular space surrounding a cylindrical subhousing (22) in the region where the Venturi 64 adjoins the outlet passage 16, and on the other side with the passage portion 67. In a modification, Fig. 4 (not shown), the passage portion 68 is omitted and a passage (67a) opens directly into the throat at the mid-height. In another embodiment, Fig. 5 (not shown), the passage portion 67 is also omitted and a single straight passage (68b) communicates directly with the diaphragm and opens into the top wall of the throat. In this latter construction, a ported sleeve (76) directs the flow downwardly into the flared passage 64 so that it does not impinge on the end of the passage (68b).

Abstract: 1279169 Pipe connections SOC INTERNATIONALE D' APPLICATION DE PROCEDES INDUSTRIELS (SIAPI) SA 19 Nov 1970 [3 Dec 1969 21 April 1970 10 June 1970] 55037/70 Heading F2G A resilient sleeve 5 (see Fig. 2) has circular throats 6, 7 at each end, each throat being bounded by a pair of lips 9, 10, and a central portion 12 whose wall thickness is greater than the remainder of the sleeve 5 except for the lips. When used to connect two adjacent plain pipe ends of pipes 1, 2 the sleeve 5 is sized such that the lips are of smaller diameter and the portion 12 of the same diameter as the outside diameter of the pipes. The lips 9, 10 and portion 12 sealingly engage the pipes 1, 2. The portion 12 may be lifted from contact by fluid pressure in the pipes 1, 2 and fluid then will fill the annular space 6 between the inner lips 10. A cover 14 may be provided about the sleeve 5 and space 19 provided for movement of the latter on connecting the pipes. Space 20 permits easy connection of the pipes and sleeve. The cover 14 may be made in two semi-cylindrical parts (14a, 14b), Fig. 3 (not shown), joined by pegs (15) fitting in grooves (16). The cover 14 has stops 17, 18 at its ends firmly clamping the sleeve 5 to the pipe. Alternatively, Fig. 4 (not shown), each end stop may be secured to or made as one piece with a rigid sleeve, two of such sleeves being joined by an annular collar to cover the sleeve 5. In a further embodiment, Fig. 6 the sleeve 36 having lips 38, 38a, 39, 39a and enlarged centre portion 40 the inner lips 38, 38a are longer than the outer lips 39, 39a and define cavities 44, 44a. A cover 43 with end stops is also provided. The embodiment of Fig. 5 (not shown) is similar but in Fig. 6 when the direction of fluid flow is shown as indicated by the arrow F the lip 44a is shorter than the lip 44 so that if the fluid pressure surges the section 40 lifts out of sealing engagement as in the other embodiments, but further the lip 44a is sufficiently short to permit the excess fluid to enter the area between lips 38a, 39a and thus escapes. When the pressure reduces the lip 44a on account of its resilience returns to the position shown in Fig. 6. The lip 44a thus acts as a safety valve. The sleeve 5 may be of natural or synthetic rubber and the covers of plastics or metal.

Abstract: 1,173,629. Roller conveyers. SANKI ENG. CO. Ltd. 7 Dec., 1967 [10 Dec., 1966], No. 55645/67. Heading B8A. In an accumulating type roller conveyer, when an article G is halted by a stop S, a roller 15, normally driven by engagement with an endless belt 18, is caused, by reaction, to move longitudinally in the direction of travel of the upper run of the belt. This movement causes a pressure roller 26 to be lowered and drive between the belt and the roller 15 to be disengaged. Drive to a roller 14 is also disengaged. The shaft 15a of the roller 15 is normally urged upstream of the conveyer by a spring support 27 which carries a bearing 29 for the pressure roller shaft 26a. The support 27 also engages the shaft 14a of the roller 14. A bearing 28 for the roller shaft 15a is located in a horizontal slot 17 in a side frame 11. The articles G are also supported by idler rollers 16. In a modification, Figs. 6-9 (not shown), the rollers (14, 15) are supported in bearings (31a, 31b) which have apertures (32) to permit adjustment of the tensioning of the spring supports (27). A further modification, Fig. 10 (not shown), comprises a spring support (34) made of resilient plastics. In Fig. 11, bearings 37a, 37c are held in position by retaining members 41 and by the edges of rectangular slots 36a, 36c. For a bearing 37b of the roller 15 horizontally elongated slot 36b is provided. Pads 18b attached to the endless belt increase the pressure exerted on the rollers 14, 15. The shafts of the rollers 14, 15, 16 are maintained stationary by stops (43), Fig. 12 (not shown).

Abstract: 1377374 TDM systems PLESSEY CO Ltd 19 Dec 1972 [2 Dec 1971] 55919/71 Headings H4L and H4P A recirculating shift register rearranges the order of bits in a t.d.m. frame TD, Fig. 3. Different channels A, B, C, supply multibit characters A1A2A3A4, B1B2B3B4, &c. the bits A1, B1 &c. of which may be grouped either as shown with successive bits taken cyclically from different channels to give a bit-interlaced frame A1, B1, C1, A2, B2, C2 etc.; or else with all bits of one character together A1-A4, B1-B4, &c. to give a character-interlaced frame (not shown). Bit-interlace to character-interlace conversion, Fig. 1.-Each bit of a complete frame is gated at GP1 by a bit-rate clock Z into shift register SRP which has as many stages as there are bits in a frame (4 Î 3 = 12). The penultimate stage is fed back to the input by stepping pulses WS through GP4, GP5 at a rate of 4 x Z, the number of bits per character being 4. Recirculation is inhibited at GP3 for the brief period during which Z clocks in the received bit. After 4 x Z ( = 48) bit periods, the stages 1-N of the register contain bits A1-A4, B1-B4, C1-4 respectively; and this character-interlaced pattern is clocked out of the register via the output gate GP7 during the succeeding frame at a selected rate by pulses RS supplied through GP6, GP4. Pulses A, B cause an identical register stage SRQ, GQ1-7 to operate on the alternate frames. The registers may alternatively have one stage less (Fig. 2, not shown) and a JK flip-flop between GP1, GP2 (GP10, GP20). A matrix of AND gates (Fig. 4, not shown) permits gaps in the frame due to empty channels to be filled by compressing bits into a continuous sequence. Character-interlace to bit-interlace conversion (Fig. 5, not shown).-The arrangement is basically similar, but incoming bits are clocked in at the bit-rate (Z, GA1) and the register (SRA) stepped forward at the same rate (WSR=Z). Then in the subsequent frame time, while an identical register (SRB) and circuitry (GB1-7) is receiving the subsequent frame, the first register (SRA) recirculates at a rate of 4ÎZ under control of another pulse source (RSR = 4 x Z) to produce the bit interlaced format. This is read out at a chosen rate by an unspecified unit (DA).
