Title: Improvements in or relating to automatic regulators
IPC: F23N3/02
Filed: 1926-06-21
Abstract: 280,977. Synthetic Ammonia & Nitrates, Ltd., and Smith, F. E. June 21,1926. Machines and apparatus.-A control device of the kind in which a control characteristic (pressure, temperature &c.) regulates the rate of leakage of pressure fluid from a pipe connected to a pilot valve and thereby controls a servomotor operating a machine part which directly or indirectly controls said characteristic has the control element and a part coupled to the servomotor connected by a device adapted to transmit rapid displacements and to ignore slow ones and so prevent over correction. The Figure shows the application of the invention to a boiler furnace control apparatus adapted to maintain a constant steam pressure. Boiler pressure is admitted at 5 to a chamber 4 and acts on a control element 1 pivoted at 2 and loaded by a spring 6. The element 1 controls the leakage from a pipe 1<a> connected to a pilot valve, the actuation of which admits or exhausts water to or from the main actuating cylinder 7. A piston 7<1> in the cylinder 7 is connected by a counterweighted chain to a pulley 8 adapted to operate a machine part 10 which in case of oil fired boilers might be the valve spindle of the fuel burner. Any displacement of the part 10 is communicated by a flexible cord 11 to a piston working in a dashpot cylinder counterweighted by weights 13 and connected through an energy storing device such as a spring 15 with the control element.

Patent GB-818382-A (GB)
Title: Improvements in or relating to the sealing of cavitated assemblies against internal pressure
IPC: B29C33/00
Filed: 1957-05-16
Abstract: 818,382. Core-boxes. OLSON, R. L. May 16, 1957 [May 23, 1956], No. 15633/57. Class 83 (1). [Also in Group XXVI] A core-box has its joint-faces 8, 9 sealed by a sealing strip 15 disposed across the joint and provided with a lateral barrier 25 which serves to prevent movement of pressurized-fluid along the sealing strip. In order to form a seal between the halves 5, 7, of the core-box shown, a sealing strip 15, formed of synthetic or plastic material such as synthetic rubber, is disposed in uncured form in the co-operating grooves 17, 18 in the halves 5, 7 on each side of the mould cavity 10; prior to the insertion of the strips 15, a bonding agent is applied to the groove 17 and a bond-preventing material such as a silicone-separator or a suspension of mica or graphite particles, to the groove 18. By the application of heat to cure the strips, a blowing agent in the material releases a gas such as nitrogen or ammonia whereby the strips 15 take up a cellular formation and expand so as to fill the grooves; they also become bonded in the grooves 17 while being separable from the grooves 18. The grooves 17, 18 are of flatbottom V-shape, the grooves 17 being somewhat wider than the grooves 18. The barriers 25 are in the form of fins arranged transversely across the strips at spaced intervals and become moulded in corresponding recesses 27 in the grooves 17 and lateral extensions 28 of the grooves 18; the width of these fins is pre. ferably greater at the inner-side of the strips than on the outer side. To prevent any leakage of sand and air, in the core-blowing operation, between the blow-plate and end-face of the core-box, from entering the groove 18, enlargements 20 are formed integrally at the ends of the sealing strips 15 and fit into mating recesses 21, 22 in the core-box; shoulders 23 are formed in the recesses 22 against which the enlargements are forced by the air-pressure. While the joint is formed of two separate strips 15 in the case when, as shown, the mould cavity 10 has end-openings 12, a single continuous strip enclosing the cavity would be provided when the cavity has no, or only one, end opening 12. Specification 818,381 is referred to.

Title: Underwater pipe-line installation
IPC: F16L1/14
Filed: 1961-05-01
Abstract: 904,854. Submarine pipe-lines. WITTGENSTEIN, G. F. May 1, 1961 [May 11, 1960; June 9, 1960; Sept. 2, 1960; Jan. 18, 1961], No. 15634/61. Class 99(2). A method of laying a submarine pipe-line 1 comprises the steps of arranging a predetermined number of motorised craft T along a sector of the pipe line at intervals correspending to the eventual points of attachment of the pipe-line to anchor weights, the craft each having a cable 5 coiled on a winch and at least one anchor weight B, passing the end of each cable through a cable locking device around a drum 4 associated with the weight and temporarily securing that end of the cable to the craft, lowering the weight to the bottom whilst allowing the cable to unwind from the winch so that the cable runs on the drum, disconnecting the end of the cable from the craft and fixing the cable to a pipe-line attachment device 6 operatively associated with the locking device, winding the cable on the winch drum so as to haul the pipe-line attachment device and pipe-line down to the required predetermined depth, and operating the locking device to maintain the pipe-line attachment device in the required position when the cable has been finally disconnected from the craft. The locking device as shown in Fig. 6 comprises a lever 11 keyed to a shaft 10 which carries a cam 14. Mounted on the lever are a weight Q and buoyant mass 13, and a sleeve 15 embracing the cable 5, when the cable is slackened, allows the lever to pivot so that the cable is jammed against the frame 6 by the cam. Re-tensioning of the cable unlocks the latter. Alternatively, a ring, bearing on the sleeve 15, produces the rocking movement of the lever. The cable 5 may be looped about the pipe-line, passed around a drum 4 of a weight B and locked by a sleeve co-operating with a plate. As a result of filling the pipeline with the material which is to be conveyed thereby and to prevent appreciable change in the buoyancy of the pipe-line sinkers 21, Fig. 8, are attached to the pipe-line and comprise e.g. a concrete block suspended from the pipe by a hook 20 and connecting members 22, 23, the hook being closed by a latch 24 held in place by a pin 25; the latter is sheared by a pull on a cord 26 to open the hook and release the sinker. The pipe-line may comprise inner and outer pipes, the former being e.g. of synthetic plastic material and conveying a liquid gaseous hydrocarbon and the outer pipe being filled with a gas.

Abstract: 420,530. Automatic - feed weighers. WALKER, R. W., 26, Munro Road, and JAMIESON, W. G., 49, Kersland Street, both in Glasgow. May 31, 1933, Nos. 15653, 18704, and 29820. [Class 143] Apparatus for feeding measured quantities of materials to mixers &c. comprises a number of receptacles for the separate materials, each receptacle tilting after receiving its quota, and interlocking means, operated by the tilting of each receptacle, whereby all the receptacles are discharged simultaneously, or in a prescribed sequence. The receptacles 1, Fig. 1, are carried in bearings on beams 3 mounted in a frame 8 and counter-balanced by a weighted beam 15. In a modified form the receptacles are directly mounted on the frame without weigh beams. They are fitted with adjustable end plates 18 whereby their capacity can be varied, and are fed through an adjustable throat 9, 10. A projection 11 rests against a stop 12 behind a pivoted catch 13 during charging. On the receptacle becoming charged, the beam 3 becomes horizontal and frees the projection 11 from the catch 13, and the receptacle tilts. The trip mechanism consists of a pivoted member 26, Fig. 7, mounted on the end of each receptacle and adapted, as the latter tilts, to engage a plate 29 pivoted to the frame to move a stop 31 on the plate out of engagement with a stop 35 on a shaft 33. The latter is connected by a forked arm 37 to a beam 39 common to all the trip mechanisms and is furnished with a radial stop 36 which engages the member 26, as shown. When all the receptacles have tilted, the respective shafts 33 are all free to turn and the receptacles complete their tilting movement. Any receptacle that has not tilted prevents this common movement by the engagement of the stop 31 with the stop 35. The receptacles return to their charging positions after discharge automatically and the beam 39 is returned by a spring to reset the trip mechanisms. In another form, the trip mechanism is arranged to discharge the receptacles in a definite sequence under hand control. For this purpose additional catches 28, Fig. 10, are arranged on the opposite sides of the receptacles to the members 26 and are engaged by latches 50, 50<a>, 50<b>. The latches are operated by levers 52, 52<a>, 52b, respectively, which are operated by spring-returned wires 57, 57<a>, 57b connected with handles 59, 59b, 62<a>. The levers 52, 52<a>, 52b are prevented from being operated by spring returned catches 54, 54<a>, 54<b>, these catches being operated by a wire associated with one of the other levers. By these means the release of the receptacles is effected in a predetermined sequence. The release can be effected simultaneously at the will of the operator by the provision of a catch 70<a> engaging a ledge 74 on the bar 39 and released by a wire 72.

Filed: 1934-05-26
Abstract: 425,513. Delivering measured quantities of liquids. MARTIN, H., 153, Broome Street, New York, U.S.A. May 26, 1934, No. 15762. [Class 106 (v)] A device for delivering measured quantities of liquid from a bottle or like container comprises a tubular portion 11 having an apertured partition 13 for trapping a predetermined quantity of liquid when the device is in an upright position the aperture 14 serving to drain off excess liquid and being of such a size that liquid below the partition will be retained when the device is inverted. The partition is conical and has an angle of approximately 66‹ between the walls whilst the aperture is approximately <9>/32 of an inch in diameter. As shown in Fig. 1, the device forms the outlet of a container 10. On inverting and shaking liquid passes through the opening 14, on righting the measured quantity is separated as shown and on again inverting the measured quantity may be run off, whilst the remainder is retained by surface tension at the aperture. In modified forms the device is separate from the container and adapted to be screwed thereto. In one form, the conical partition screws on to the neck of the bottle or container and on a neck portion of the partition is screwed a cap member which receives the measured quantity and which may be used as a drinking cup. In the form shown in Fig. 7, the neck of the container or bottle 55 is formed with a bead 56, a screwthread 58 and an external enlargement 59 extending about a third of the way round the neck, the ends of the enlargement forming abutments for the ends of a strip of metal spring 70 which extends round the other two thirds. The measuring device is formed with a screw-thread and with ratchet teeth 62 adapted to be engaged by tongues bent up from the spring 70 so that the device may be screwed on to the bottle but cannot be turned in the reverse direction to be removed from the bottle. In a further modification, the measuring device in addition to an internal locking device similar to that described above, is provided with an external locking device, Fig. 9, comprising tongues 87, bent inwardly from a metal collar 81 surrounding the bottle neck and engaging teeth 97 formed on the exterior of a skirt portion 90 depending from the measuring device.

Title: Improvements in porcelain enamel and method of making same
IPC: C23D5/00
Filed: 1950-06-27
Abstract: 674,696. Enamels. FERRO ENAMEL CORPORATION. June 27, 1950 [Jan. 19, 1950], No. 16031/50. Class 56. A ceramic slip or clay free porcelain enamel slip comprises a liquid suspension of a finely divided frit and a minor proportion of a synthetic organic surface active agent. The surface active agent serves to suspend the frit without the use of clay which has certain disadvantages. A cationic surface active agent may be added and if the slip sets up too much or becomes too thick an anionic surface active agent may be added to make the slip thinner or less viscous, and thus the set may be controlled. In combination with the surface active agents, which are preferably water soluble, mill additions such as KCl, K 2 CO 3 , NaNO 2  &c. may be used to eliminate " tearing," and NaAlO 2 , KF &c. to obtain hardness. Examples of cationic surface active agents are Emcol 888 (alkyl-oryl pyridinium chloride), Triton K-60 (alkyl dimethyl benzyl ammonium chloride), Abro Quaternary O (high molecular weight imidazolinium chloride) and Alkaterge C (substituted oxazoline), and of anionic surface active agents, Ultrawet 30E (alkyl aryl sulphonate), Nopco 1067 (sulphonated alkylated aromatic), Michelene DLC (alkyl aryl sulphonate and alkyl amido alcohol). A volatile organo-halogeho-silane such as methyl chlorosilane may also be used to prevent the frit from settling, the frit being ground dry in a ball mill in a moisture-laden atmosphere containing the silane, when the frit particles acquire a surface condition which makes them water repellent. A suitable slip contains, in parts by weight, Frit 100, KCl 0.5, NaAlO 2  0.75, Emcol 888 0.032, water 46.0, and when fired has a high surface gloss, uniform colour, high resistance to acid attack, and high scratch resistance. Small quantities only of the surface active agent are necessary, e.g. 0.001-0.5 per cent, and the amount of agent used is based on the active ingredient, since the agent contains water or other inert ingredients, thus 1.56 per cent of Triton K-60 is added to get 0.39 per cent of active ingredient in the slip. The agents may also be used to control the set of clay containing slips, particularly non-acid resisting enamels where the clay gives a hard bisque coat and aids opacification. If the clay containing enamel is set too low a cationic surface active agent is added, and if too high an anionic surface active agent. The agents may also be used to control the set of clay containing ceramic porcelain casting slips.
