Title: Method and machine for making concrete pipes
IPC: B28B21/90
Filed: 1965-09-28
Abstract: 1,117,215. Moulding concrete pipes. BELOIT CORPORATION. 28 Sept., 1965 [30 Nov., 1964], No. 41213/65. Heading B5A. In a concrete pipe mould, a bottom annular pallet 18 is located on a retainer ring 30, of a stationary core 12, and is engageable by sprung pawls 19 located in an outer mould jacket 16 whereby the moulded pipe is stripped from the core, upon raising the jacket 16 by hydraulic cylinders 20; a fresh pallet (78) on which is superimposed a disc (84), is inserted and engaged into the base of the jacket (16) beneath the pawls (19), (Fig. 2, not shown), so that, upon retracting the jacket (16), the pallet (78) slides down the core (12) into engagement with the ring (30), followed by engagement of spring pawls (19) beneath the pallet (78), and the moulded pipe and pallet (18) are retained upon the disc (84) on top of core (12) for removal by a fork lift truck. The concrete is fed into the cavity 17 from a rotated spiral feed blade 22 mounted at the upper end of core 12, and the outer jacket 16, which is rotatably mounted on brackets 42, attached to cylinder rams (44) is oscillated over 15 to 25 degrees by a pair of double acting power cylinders (68), (Figs. 4 and 5, not shown), whereby slippage between the concrete in the cavity (17) and the mould parts produces a trowelling and compacting action, the upper end of the cavity 17 being closed by a plunger 130 which is swung into position on a power cylinder 106 on boom 26 and is lowered to close the mould by a power cylinder 123 and is oscillated, when in position, by a pair of power cylinders 144, vibration being provided by a vibrator 150 resting on the plunger assembly 130.

Abstract: 1438873 Pneumatic shuttle conveyers SIEMENS AG 3 Sept 1973 [22 Sept 1972] 41304/73 Heading B8A A pneumatic shuttle conveyer system comprises a plurality of tube strings operated in single-tube turn-round fashion and issuing into a main string via a branch connection, each string having an individual blower means and tube-closing means at the end zone of the tube adjacent the branch connection, the tubeclosing means being controlled by a destination control device to separate the zone from, or connect the zone to, an airway in the main string. In the figure, tube strings R1, R2, R3 are connected via branch connections to main string R0. Each branch connection comprises two valves T01, T10; T02, T20; T03, T30 between which extends a section of tube with an air connection so that a shuttle comes to rest in the tube section until an air current moves it past the second valve and into the main string. Shuttles may be moved from one tube string to another via the main string.

Abstract: 991, 674. Electric selective signalling systems. PERKIN-ELMER CORPORATION. Nov. 1, 1962 [Nov. 8, 1961], No. 41401/62. Heading G4H. In a shaft-position encoder a single brush 20, Fig. 2, moves over 1000 contacts 001, 002 &c. connected together in 18 groups-these being indicated by the circled numbers-and each group is connected via conductors 1, 2 . . . 18, Fig. 1, to two of a set of 12 triggers 23, 24... 35, constructed from transistors, Fig. 3 not shown, which, via relays and weighted resistors, control ammeters 78, 80 and 81, the arrangement being such that (i) as the brush moves over the contacts the markings produced on the 18 group conductors indicate which triggers are to change their states so that the ammeters indicate the shaft position and (ii) the 12 triggers are brought into phase, or registration, with the shaft position from any initial combination of states once the brush has passed over 10 contacts. This second property of the circuit is made possible by using a monophylic-binary coded monophylic-decimal arrangement for the 12 triggers. Thus normally, when registration has been achieved, only one trigger changes its state for each incremental displacement of the shaft, so that, normally of the two connections made to the triggers from each group conductor, one is redundant. However, these redundant connections are so chosen, the theory being given in the Specification, that after the shaft has turned through 10 incremental positions, all of the triggers will have been set in registration with the shaft.

Title: Fluid flow divding valves
IPC: F16K11/00
Filed: 1964-10-13
Abstract: 1,080,927. Valves. CESSNA AIRCRAFT CO. Oct. 13,1964 [Aug. 14, 1964], No. 41746/64. Heading F2V. A liquid flow dividing valve suitable for controlling a high and low capacity circuit has an inlet 11 and two outlets 12, 13, and when the flow rate is small the liquid divides equally and passes through restrictions 23, 24 to the outlets via a bore 15 in which is mounted a spool 16, the spool having a reduced diameter portion defining an annular chamber 19 which communicates via a bleed hole 20 with a chamber 18 at the end of the spool. If the resistance of either outlet increases, the resulting backpressure will shift the spool to again equalize the flow by increasing the area of the port 27 or 28 leading to that outlet and decreasing the area of the port leading to the other outlet. In a modification, the restrictions 23, 24 may be of different size, in which ease the relative throughputs will be in proportion to the sizes. With high flow rates the valve functions as above until the pressure drop across restriction 23 is sufficient to open the check valve 25 and thereby permit a priority flow to outlet 12 which may serve the high capacity circuit.

Abstract: 1,024,697. Electric playback apparatus. BSR Ltd. Nov. 13, 1963 [Nov. 13, 1962], No. 42803/62. Heading G5R. In a pick-up arm and cartridge assembly of the type in which the cartridge swings upwards relatively to the pick-up to afford protection of the record when accidental misuse causes excessive pressure to be applied to the pick-up arm the cartridge is carried by a pivoted mounting plate 33, which engages a lever 15, 16 such that upward movement of the lever selative to the pick-up arm, when an abutment 20 engages the record surface, causes upward movement of the stylus to a greater extent. As described, the lever is formed as a skirt having two spaced apart sides 15 and an end portion 16, which depends from the underside of the pick-up arm, and is pivoted on a bearing 17. The mounting plate for the cartridge comprises two arms 33 linked by cross-members arid pivoted on a bearing 36. Projections 43 on the mounting plate engage with lips 37 on the skirt so that the upward movement of the skirt due to abutment 20 engaging the record surface moves the mounting plate upwards to lift the stylus clear of the record surface.
