Title: Improvements in loose leaf binders
IPC: B42F13/00
Filed: 1925-10-22
Abstract: 241,927. Edler & Krische, (Assignees of Ziegenbein, K.). Oct. 23, 1924, [Convention date]. Post files; locking-followers; clamping-devices. -In a loose-leaf binder comprising telescopic posts, one section of each post is partly or completely enclosed, together with ratchet adjusting- mechanism, when provided in one of the clamping-bars. The lower extremity of each filing-post d, slides in a socket c in the clamping-bar a and is provided with a flange e adapted to be engaged by a toothed block f carried by a spring-pressed bar g. The posts are released by pressing against the end r of the bar g. A spring n, which may be loose on a pin l in the post d, or may be rigidly secured to the post d and the clamping- bar a, serves to force the members c, d apart. The socket c may be dispensed with, and the hole in the clamping-bar a adapted to receive the end of the post d. The free end of the post d passes through a clamping-bar b and may have attached thereto a block p, which screws into the end of the post d, and carries a pivoted right-angled extension q, the outer arm of which engages elongated slots in the leaves. The ratchet mechanism may be dispensed with, and the spring n replaced by a tension spring. The Specification as open to inspection under Sect. 91 (3)) (a) comprises also a construction in which the bar g is in two parts, slightly separated, so that the posts are not released together. This subject-matter does not appear in the Specification as accepted.

Title: Self priming system for horizontal pumps
IPC: F04D9/00
Filed: 1967-06-09
Abstract: 1,134,479. Self-priming centrifugal pumps. HUDSON ENGINEERING CO. June 9, 1967 [June 10, 1966; April 10, 1967], No.26689/67. Heading F1C. A self-priming pump 20, Fig. 1, having a horizontal inlet 6 draws liquid from a suction line 40 via a suction well 4 having a cavity which is at least in part below the inlet 6 and is connected at its upper part to the suction line 40. A suction pipe 5 extending from the inlet 6 towards the bottom of the suction well 4 may, as shown, be curved upwardly so that the lower inner surface of the upper portion is approximately level with the upper inner surface of the inlet 6, and an air bleed aperture may be provided in the upper portion. The pump discharge through a discharge column 8 containing a repriming valve assembly 30. During normal flow, the depression occurring at the throat of a Venturi in the lower part of the inner casing 34, Fig. 2, of the assembly 30 and communicated via tubes 35 to cylinders 36, maintains poppet valves 31 closed. If the pump loses its prime, the valves 31 are opened by springs 37 and liquid in the discharge column 8 and assembly 30 returns via the valves 31 and a drain pipe 9 to the suction well 4. The air displaced from the suction well 4 by the returned liquid passes via a pipe 10 and a non-return valve 11 to the discharge column 8 at a point upstream of the main non-return valve 12. When the returned liquid has risen through the suction pipe 5 into the inlet 6, it is passed by the pump 20 into the discharge column 8. The resultant flow through the Venturi within the valve assembly 30 causes the valves 31 to close. The non-return valve 11 closes, and the air which has entered the discharge column 8 is forced through the non-return valve 12 into the discharge line 42. The reduction of pressure in the suction well 4 due to the removal of the liquid from the suction well draws liquid up through the suction line. The cycle repeats until priming is completed. In a modification, Fig. 3 (not shown), a pipe (63) is provided to pass entrapped air from the impeller inlet casing (64) to the suction well (4) or to the upper end of the discharge column (8).

In apparatus for delivering measured quantities of liquids, of the type having a free piston 2 oscillafed in a cylinder I by the pressure of the liquid to be measured, the movement of the piston into its extreme positions operates a valve or valves controlling the inlet and discharge of the liquids. As shown in Fig. 1, a pair of slide valves 7 and 8 have abutments 9, 10, 11 and 12 which are engaged by the piston 2 to control inlet ports 3, 4 and outlet ports 5, 6 close to each end of the cylinder. In the form shown in Fig. 3, the piston through push rods 35, 36 operates electrical switches or hydraulic valves connected to an electric or hydraulic relay which turns an interconnected pair of valves 27, 28 to the appropriate inlet or discharge positions. The gland tube 43 for the push rod 35 can be adjusted in position to vary the stroke of the piston and clamped by a split cone 45 and nut 44. An air cock may be fitted at a high point in the liquid supply line 31 or on the cylinder, for freeing the apparatus of air before use.

In a coaxial communication cable, of the type having a coaxial tube consisting of a core A spaced from a single tubular conductor C and having additional conductors laid up with the tube to provide control circuits, the additional conductors comprise flat pairs of plastic insulated wires 1 and 2 laid around the tube with a long lay in equidistant parallel relationship. The spaces between pairs may be filled with threads 4 and 5 or tapes of polythene or other dielectric material and if the cable is screened, e.g. by a short lay aluminium tape 7, bare metal wires 3 may also be laid in these spaces in contact with the coaxial tube and the screen to form screening pockets 4 to reduce the screen resistance. These wires may be of high tensile strength to enable the cable to be used as a self-supporting overhead line. The flat pairs may be transposed at splices to effect cross-talk balancing. A sheath D of p.v.c. or polythene may be provided.
