Title: Improvements in or relating to apparatus for moulding pipes and like hollow articles from concrete or similar material
Inventor: LIVINGSTON WILLIAM DAVID
IPC: B28B21/26
Filed: 1949-03-24
Abstract: 675,288. Moulding concrete pipes &c. LIVINGSTON CONSTRUCTION CO., Ltd. March 10, 1950 [March 24, 1949], No. 8069/49. Class 87(ii) A machine of the type having an intermittently moved table carrying at least two moulds in which pipes or the like are made by the dry packing method, the moulds being presented in turn to the packing head, comprises means for automatically delivering a measured quantity of concrete or the like to a mould when the mould is positioned in register with the packing head. The machine shown is of the intermittently-rotated table type, the table 3 carrying moulds 4 below a packing head 10. The delivery means comprises a hopper having its outlet controlled by a rotary paddle-wheel 9 which is intermittently rotated through 90 degrees by a cam 12a on a main shaft 12, this cam acting through lever 11c, rod 11b, pawl 11a and ratchet 9a. A regulated quantity of concrete &c. thus falls down shoot 8c and through a ring 14 which rests on the mould being filled. Ring 14 is resiliently secured by rods 5a to plates 5d fixed to collars 5g resting on stops on tubular packing head guides 5. Each mould 4 is split vertically, one-half being fixed to the table and the other half being removable. The table is intermittently rotated from the shaft 12 which is driven by a motor 22, the shaft carrying a cam 12c acting on rollers 16a, 16b on lever 16 pivoted at 16c, this lever being connected by a rod 17 and a pawl-andratchet device to the table. The table is locked in position by a spring-urged pin 18 entering recesses therein, the pin being withdrawn by rod 17 when the rod is moved to rotate the table. The packing head 10 is carried by a tubular shaft 7 fixed to a sleeve 7b rotatable in bearings 7c in a crosshead 6, this sleeve being rotated by a square-section shaft 7a driven by gearing from motor 22. As the packer head rises, shaft 7 telescopes over shaft 7a. The packer head is raised and lowered by cam 12b on shaft 12, this cam acting on roller 15a on lever 15 pivoted at 15b, the lever being forked at 6b to engage the crosshead and the crosshead sliding up and down on the guides 5. Operation:-The machine being in the position shown, concrete is filled into the mould and the packer head rises. When the packer head gets to the top of the mould, crosshead 6 raises collars 5g off their stops, thus raising collar 14 off the filled mould. Then rod 17 withdraws locking pin 18 and turns the table to position an empty mould beneath the packer head, rod 17 returns to its original position, the locking pin springs back into position, crosshead, packer head and collar return to the position shown, and wheel 9 turns to deliver concrete to the mould. There may be two or more parallel packing heads cooperating with one mould or with a corresponding number of moulds, for producing either an article having parallel bores therethrough or two or more pipes &c. Specification 675,297 is referred to.

Title: Liquid packing for joints between sliding or rotating machine parts subjected to fluid pressure
IPC: F16J15/40
Filed: 1923-03-22
Abstract: 219,362. Cooke, N. March 22, 1923. Liquid seals; connected to source of high or low pressure.-A rod or shaft is packed by a viscous liquid on which the pressure to be retained acts by means of a plunger, the latter also operating or constituting a valve for admitting replacement liquid. A sleeve 3, Fig. 1, transmits the pressure to liquid in a chamber 6 packed by rings 4 and 10. The liquid leaks slowly past the ring 10 to the space between the ring 10 and a ring 13, drained by an outlet 11. The leakage is replaced by liquid admitted from a pipe 8 by a valve 15 in a casing 7, Figs. 1 and 3. The valve is carried by a ring 5 secured to the member 3, and ports 16 in the valve are opened when the pressure falls. In a modification, adapted for rotating shafts, the valve 15 moves freely in a separate casing and is acted on at its ends by the pressure to be retained and the pressure in the packing space, the member 3 and ring 5 being dispensed with. When applied to a reciprocating shaft, the make-up valve may be arranged to put the liquid space in communication with the draining space if the liquid pressure rises unduly. Specification 15690/06, [Class 122, Steam engines], is referred to.

Title: Improved method of and devices for automatically regulating alluvial washing machines
IPC: B03B11/00
Filed: 1948-03-18
Abstract: 662,643. Washing granular material. HOUILLERES DU BASSIN DU NORD ET DU PAS-DE-CALAIS. March 18, 1948. [Dec. 17, 1947] No. 8151/48. Class 82(ii). [Also in Group XXIX] Alluvial washing machines having at least one of a number of boxes traversed by an ascending current of water are automatically regulated by utilising variations in the hydraulic pressure prevailing in one or more of such boxes to control, directly or indirectly, the discharge of the heavy- and medium-weight products in the boxes either by varying the ascending current of water or by varying the cross-section of the outlets or both. Control may be effected by means of a pneumatic, hydraulic, electric or mechanical relay, or directly. As shown in Fig. 1, a float 3 in a tube 2 connected to a pressure take-oif from the box A, actuates, through a linkage 4...9, a flexible hose 10 connected with an auxiliary water supply and opening into a box 12 having a partition 12a and, on either side of the partition, a tank 11 and discharge 13; the tank 11, movable with respect to the box 12, discharges through a metering orifice 14. By this means the amount of water contained in the tank 11 is a function of the position of the hose 10 and therefore of the pressure in the box A. The tank 11 is suspended from a cable 15 connected to one arm 16 of a valve 17 counterweighted at 16a, 16b, the valve 17 controlling the upward flow of water in the box A. The lever 5 is also connected to a bell-crank 20 controlling a lever 21 moving over a graduated scale 22 whereby the setting of the automatic regulating device may be manually adjusted by raising or lowering the pivot 18 of the link 5. Such adjustment may also be effected in accordance with the pressure prevailing in another box B by means of a float 23 connected through a cable 24, counterweighted lever 25 and rod 26 to the bell-crank 20. In another form, Fig. 2, the pressure take-off from the box C is in the form of a flexible hose 29 to which is secured a head 30 having a slot 31 opening into a nozzle 32 discharging into the tank 11. Specification 301,812, [Class 82(ii)], is referred to.

Title: Improvements in or relating to methods of tracing interference signals on record carriers
IPC: H04R29/00
Filed: 1964-02-27
Abstract: 1,018,790. Monitoring methods and circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 27, 1964 [March 1, 1963], No. 8221/64. Heading H4J.  Impulsive interference on record carriers carrying audio-frequency signals is detected by playing backwards the record carrier and applying the resultant signals to a circuit including means which pass only the frequency range characteristic of the interference signals and means which respond to the difference in rise time of the leading edges of the interference signals and the leading edges of the useful signals in the play-back movement of the carrier. The trailing edges of impulsive interference signals are steeper than the trailing edges of useful signals by virtue of the fact that useful signals decay slowly. Detection of the impulsive interference may cause operation of a relay or registering instrument. Drop-outs in magnetic tape may be detected. A filter 1 (Fig. 6) passes only the frequency range characteristic of interference signals and applies them to a full-wave rectifier 2. The rectified signal is applied through a voltage divider to one input of a differential amplifier 7 and through an integrator comprising resistor 4, capacitor 5 and resistor 6 to a second input of amplifier 7. Amplifier 7 is adjustedto provide an output only if an interference signal occurs. Full-wave rectifier 2 ensures that interference signals having either a positive or negative peak are detected. The output may stop a gramophone or tape play-back machine utilizing the carrier. An adjustable voltage divider 9, together with a rectifier 10, may be provided to apply a portion of the non-filtered signal to integrator 4, 5, 6 so that only interference signals having apredetermined amplitude are detected. An adjustable direct voltage may also be applied through a diode 11 to the integrator so that, for example, in the absence of useful signals, very small interference signals are not detected. In an alternative arrangement (Fig. 3, not shown) a filter 1 passes only the frequency range characteristic of interference signals to an amplifier 8, the output voltage of which is limited for input signals having a rise time up to 60 db. per 40 m/sec. (i.e. useful signals). The output signal of filter 1 is also applied to a rectifier 2, the output of which is applied to an integrator 4, 5, 6. The output of the integrator controls the amplification of the amplifier 8. If an interference signal occurs, the output signal of amplifier 8 will temporarily exceed that to which it is limited for useful signals.
