Title: Improvements in power actuators or servo motors
IPC: B60T13/24
Filed: 1924-11-24
Abstract: 226,514. Bragg, C. S., and Kliesrath, V. W. Dec. 22, 1923, [Convention date]. Steering-gear.-For operating steering gear normally operated by manual means, a power device is employed which is controlled by the usual manual means, the latter being adapted to operate the steering gear when the power device is inoperative. The power device comprises a piston and cylinder, the control of fluid thereto being effected by the manually operated valve. In one example, the suction in the inlet manifold of an internal-combustion engine is utilized or compressed gases from the engine may be employed. The power device comprise a cylinder 1, Fig. 2, the front and rear heads 2, 3 being formed with guides for the control valve 16 and piston rod 12. The piston 10 has cup leathers 11 and also a packing ring 14<a> for cushioning. In an installation for operating the brakes oi a motor-car, the valve rod 9 is coupled by a rod 62, Fig. 1, to a brake peda 50, the port 20 in the head 2 is con nected to the inlet pipe 21 of the engine 22, and the piston rod is con nected by a rod 63 with the brake levers. Alternatively the port 20 may be connected to a vacuum chamber 23a which is in valved communication with the inlet pipe. On pushing forwards the pedal 50, the collar 18 on the hollow valve is moved clear of the port 19 and the openings 24 are drawn clear of the piston whereupon the space in the cylinder to the left of the piston is in open communication with the vacuum port 20 and the piston is drawn to the left. At the same time the dividing collar 29 is to the left of the ported passage 36 in the piston boss, so that air can enter the space to the right of the cylinder through the open end of the valve, ports 25 and passage 36. In the event of a defect in the vacuum service the collar 29 contacts with the piston and moves it and its rod 12 manually to effect control of the brakes. The brakes can be held in any given position, by positioning the valve so that the collar 37 closes the passage 36. On releasing the pedal, the spring returns the valve and the piston to the positions shown in Fig. 2. For power action to the right, the ports 25 are open to the port 39 and passage 40 for passing air to the left of the piston, whilst the right hand side is open to the vacuum port 20 through the ports 20 and passage 30. The operated part is held in any given position, when the valve collar 29 is centrally positioned in the reported sleeve in the piston boss. Instead of the rod 12 being open to the atmosphere, it may be connected to a cylinder of the engine, compressed air supply, steam boiler, or other source of power supply. For operating the steering gear of a motor boat, the power device 87, Fig. 9, is coupled to the steering head 84 and the valve to the steering lever 85. The suction side is connected to a vacuum chamber 91 in communication with the inlet pipe 94 of the motor 82, and the pressure side is connected to a pressure chamber 97 in communication with one of the cylinders.

Patent GB-600693-A (GB)
Title: Foam reducing compositions and methods of producing same
IPC: C08G77/28
Filed: 1945-10-30
Abstract: A foam inhibitor suitable for lubricating oils, e.g. motor oils and detergent or "H.D." lubricating oils, comprises a hydrocarbon or mixture of hydrocarbons having a viscosity of less than about 50 S.U.S. at 100 DEG  F. and containing dissolved therein a minor proportion of an active foam-reducing compound of the formula <FORM:0600693/III/1> wherein R represents the same or different saturated non-aromatic hydrocarbon radicals and n is a positive integer of at least 2. Each R may be a saturated alkyl radical such as methyl, the active defoaming agent being for example polymerized dimethyl silicone, and the hydrocarbon mixture may be an aliphatic petroleum fraction having a viscosity of between 40 and 50 S.U.S. at 100 DEG  F.  The composition may also contain an active amount of an oil-soluble detergent tending to increase foaming, such as a diphenate of an alkaline earth metal.  The composition may be incorporated in a lubricating oil by agitating the mixture by passing a gas through it and the hydrocarbon solvent for the active defoamer may be sufficiently volatile to be substantially removed from the lubricating oil by the passage of the gas, leaving the silicone or other active defoamer (which is insoluble in lubricating oils or nearly so) dispersed throughout the lubricating oil The concentrations of the polymers of low molecular weight silicones, particularly dimethyl silicone, may range from about 0.0001 per cent to 0.01 per cent by weight and seldom above 0.1 per cent of the lubricating oil.  Larger proportions of polymers of higher mol. weight silicones, e.g. of dicetyl silicone, may be used, for example 0.05 per cent to 0.5 per cent by weight, particularly in soluble cutting oils containing very viscous base oils and considerable proportions of emulsifier.  Silicones containing not less than about 24 carbon atoms per monomeric unit are most effective foam inhibitors for oil-in-water emulsions, and those containing about 10 or less carbon atoms per unit are preferable for controlling foaming of water-in-oil emulsions and single phase organic liquids such as hydrocarbons.  Specifications 542,655, [Group IV], and 572,331 and J.A.C.S. 63, 798 (1941) describing the manufacture of silicones are referred to.

Title: Method of lining with cement mortar underground conduits having branch lines
IPC: B28B19/00
Filed: 1952-11-17
Abstract: <PICT:0711335/III/1> In the lining of a conduit having a branch pipe connection by spreading cement mortar under pressure on to the inside walls of the conduit to form the lining, and thereby also filling the end of the connection with mortar, the mortar is removed from the connection by bringing the latter into communication with a high pressure source of fluid while the mortar in the connection is still in a relatively soft condition, the pressure of the fluid being sufficient forcefully to project the mortar from the connection and to distribute it on to and into the mortar lining on the opposite wall of the conduit, to form a permanent part of the lining.  As shown, a mass of mortar 12 is placed in a conduit and applied to its walls by a spreader 10, which is dragged forward by a cable 13, the spreader exerting sufficient pressure on the mortar partially to dehydrate it, and having perforations 11 to allow escape of the expressed water.  At the same time mortar is pressed into the bore of the branch pipe 16, the amount entering being limited by shutting the valve 17.  A storage cylinder 19 containing air, oxygen or other suitable gas, preferably under 80 to 90 pounds per sq. in pressure, and having a quick-acting valve 20, is then connected to the branch pipe, e.g. at a service connection 18, and, with all branch valves open, the valve 20 is quickly opened to project the still soft and plastic plug from the branch pipe 16 to the opposite side of the conduit, where it forms a depression in the lining 14 which is then filled by the projected mortar.  The time at which this is done is so chosen that the mortar in the pipe 16 has the consistency of soft butter, the material of the lining, in view of its partial dehydration, being rather firmer.
