Abstract: 1276629 Reciprocating pump; producing pressure pulses VSESOJUZNY NAUCHNOISSLEDOVATELSKY I PROEKTNO-KONSTRUKTORSKY INSTITUT DOBYCHI UGLYA GIDRAVLICHESKIM SPOSOBOM 20 Feb 1970 8343/70 Headings F1A and F1P A device for producing high pressure pulses in a liquid and operable as a pump comprises a pumping piston 9 connected to a working piston 10, the pistons being mounted in a cylinder 1 divided by a partition 11. For the suction stroke, pressure liquid is supplied via pipes 14 and 30 to the annular chamber 12 in front of the piston 10, while the annular chamber behind the piston 9 is connected to a drain line 15 via a pipe 32 and a slide valve 16, and as the piston 10 moves back, gas behind the piston is compressed and forced through apertures 5 into a vessel 6. Pressure liquid is also supplied via throttle valves 22, 23 to a chamber 4 and the space in front of the piston 9. At the end of the suction stroke, the piston 10 engages a projection on a slide valve 18, moving its spool 20 to connect an annular space 28 between the casing and a spool 17 of the valve 16 to the drain line 15, enabling the spool 17 to move to the right, under the action of a spring 31 and pressure liquid which is continually supplied to a second annular space 29, connecting pipe 32 and hence chamber 12 to the liquid supply line 14. The pistons 9, 10 now perform the pumping stroke, a plunger 21 projecting from the piston 9 impacting the liquid in chamber 4 producing a pressure pulse. Pressure liquid supplied to the space 34 behind the spool 20 moves the spool to the left forcing liquid from the annular space 37 via a throttle valve 39 which is adjustable to vary the pumping rate. The spool 20 now connects the annular space 28 to the pressure line 14, spool 17 is moved to the left due to the differential area, and the chamber 13 is connected to the drain line 15 to commence another suction stroke. Reference has been directed by the Comptroller to Specification 1081076.

Title: Improvements in or relating to the production of contraction and expansion joints in concrete roads and the like
IPC: E01C11/04
Filed: 1935-03-18
Abstract: 453,708. Joints in concrete roads. WINKLER, K., Lugano-Crocifisso, Casa Crocifisso, Switzerland. March 18, 1935, No. 8454. [Classes 20 (ii) and 20 (iv)] Expansion and contraction joints in concrete road surfaces are formed by inserting into the road concrete, before the latter has set, a finegrained concrete or cement strip at each place where a joint is to be formed, and cutting a joint in such strip when the fine-grained concrete has lost its plastic condition, but before it has completely hardened. The joint may be cut by cutters of the circularsaw type. In one construction, the ordinary road concrete containing coarse aggregate is cast adjacent the place at which a joint is to be formed against a mould board, and after removal of this board the fine-grained concrete strip is cast, and further road concrete is cast against the opposite side of this strip. The casting of the road concrete between adjacent joint strips is then completed and both the road concrete and fine-grained strip are mechanically worked by kneading and tamping tools. If desired, both the road concrete and the fine-grained concrete may be cast in two superposed layers a, b as shown in Fig. 3, the lower layer a being tamped and finished before casting the second layer b. A finishing and surface layer may also be provided. In another arrangement the road concrete is cast on both sides of a tapered mould h, Fig. 4, which is either in the form of a channel iron or a board covered with metal, and fine-grained concrete is cast in the channel formed on the withdrawal of the mould. The whole of the concrete is then finished by means of tamping and kneading tools. The joint strip may also be formed by means of a hollow mould formed of two tapering walls m, n as shown in Fig. 5, the road concrete being, cast and tamped on both sides of this mould, and fine-grained concrete is cast and tamped in the mould. The road concrete is banked upon each side of the mould and the fine-grained concrete is cast to a higher level than that of the finished road surface so that after withdrawal of the mould the spaces formed by the walls are filled when the road surface is tamped. The fine-grained strip may consist of cement containing no sand or sand having a grain size of from 1 to 3À5 mms.
