Filed: 1951-03-05
Abstract: 688,735. Fluid-actuated valves. BASTIANBLESSING CO. March 5, 1951, No. 5317/51. Class 135. In a spring-loaded diaphragm pressure regulator, particularly for liquefied petroleum gas, outlet pressure raises the diaphragm to close the regulating valve and then raises the diaphragm against another spring away from the end of the regulating valve operating lever to open a relief passage through the diaphragm. The pressure regulating valve comprises an inlet nozzle 3 and an outlet 71 in a body chamber 5 separated from a bonnet chamber 46 by a diaphragm 23 loaded by a spring 22 adjustable by the screw 31, to move through a lever 16 a plunger 9 carrying an elastic closure chamber 11 to and from the nozzle. The lever is connected to a yoke 17 which is pressed on to the diaphragm by a spring 18 acting through a rod 19 so that excessive pressure in chamber 5 raises the diaphragm against the springs and relieves pressure around the yoke and rod and through a central hole 42 in the diaphragm to the chamber 46 open to atmosphere through opening 45a. A vent 13 in the plunger prevents the accumulation of fluid behind the seal 11.

Title: Improvements in and relating to colloid mills
IPC: B02C19/18
Filed: 1939-02-17
Abstract: 525,323. Colloid mills., PLAUSON, H. Feb. 17, 1939, No. 5368. [Class 59] [Also in Group III] A colloid mill comprises a rotor and stator provided with corresponding recesses and projections, the breadth of the spaces being greater than that of the teeth so that the liquid is passed around the mill with periodic interruptions whereby vibrations of a rhythmic nature of high frequency and large amplitude are produced mechanically to effect a grinding and-or dispersing action in addition to a rubbing and beating action. As shown, the rotor has teeth 4 and recesses 6.which correspond to similar teeth and'recesses on the stator. The stator may be water cooled and liquid from a hopper 1 is led through a valve 2 to an inlet 3 and after passing around the mill is discharged through an outlet 7 to a pipe 8. This pipe is connected to a branch 9 leading from the mill and also to the hopper 1 for recirculating the liquid so that when the liquid is discharged part of it still circulates and prevents excessive pressure on the mill. The space between the inlet and discharge outlet on the stator is plain and a flexible strip, adjusted by a screw, may adjoin the trailing edge of the discharge outlet to prevent the liquid from recirculating around the rotor. Several blank spaces may be formed around the circumference of the stator. The recesses, as shown in Fig. 3, may be formed at a steep angle on the leading or trailing side of the teeth. The ratio of tooth width to gap may be from 1:2 to about 1:6, the ratio depending on the diameter and speed of the rotor and these dimensions may be varied according to the number of vibrations per second required.

Title: Improvements in or relating to fuels for furnaces
IPC: C10L1/32
Filed: 1958-02-24
Abstract: A fuel for combustion in a furnace wherein at least part of the heat transfer from the flame is by radiation, comprises a residual fuel oil that has been treated with a precipitating agent to give a suspension in the remainder of the fuel oil comprising solid components having a molecular weight greater than 1000.  The oil may be treated between 1 second and 24 hours before combustion. The precipitating agent may be a paraffinic hydrocarbon having from 3 to 20 carbon atoms in the molecule, and may be an extracted kerosene fraction.  The precipitating agent is added in an amount between 20 and 80% by weight based on the fuel oil.  The size of the particles suspended in the oil may be between 0.5 micron and 150 microns, and preferably at least 10% by weight have diameters less than 0.5 micron, and at least 10% by weight greater than 10 microns.  The residual fuel may be a bottoms fraction obtained by straight-run distillation of crude petroleum, a cracked product from a crude petroleum or a flashed crude petroleum, a catalytically-cracked gas oil or a thermally or catalytically cracked reformate derived from crude petroleum.  The amount precipitated from the residual fuel oil may be between 1 and 10% by weight based on the total amount of the fuel oil.ALSO:In a method of steel manufacture in an open hearth furnace in which a residual fuel oil is burnt, the fuel burnt during the period for charging and melting is treated with a precipitating agent to give a suspension of solid components in the fuel, and the fuel burnt during the refining period does not contain such a suspension.  The oil may be treated between 1 second and 24 hours before combustion.  The precipitating agent may be an extracted kerosene fraction, and 1.5 to 5% by weight of the residual fuel oil may be precipitated, the suspension having a particle size of 0.5 to 150 microns.  The presence of the suspension increases the rate of heat transfer by radiation.

Title: A method or means by which a number of separate types can be simultaneously cast at each pouring of the metal
IPC: B41B7/04
Filed: 1919-03-12
Abstract: 142,600. Gibbons, J. T. March 12, 1919. Single-type composing and casting machines; keyboards; moulds; assembling, clamping, and distributing matrices; metal pots and pumps.- A line of separate types is produced from a composed line of matrices at one operation of the metal-pump by means of division-pieces which form partitions in the mould and are released automatically by the depression of the character and space keys so as to be assembled alternately with the matrices and spacers. Division-pieces of the form shown in Fig. 2, are contained in a box at the rear of the assembler and are released by a reciprocating tongue or eccentric actuated by a bar 2, Fig. 8, resting in slots in the escapementrods 1. Alternatively, the bar 2 may rest on pins projecting from the rods 1, or may be operated by the key-rods 10, the keyboard cams 12, 12<a>, the sparrows 11, 11<a>, or the key-levers. To allow for the varying number of matrices and divisionpieces in the line, the assembler slide-bar is constructed in two relatively sliding sections 5, 6, Fig. 4, which are connected by escapement or like mechanism 4 operated by the bar 2, so that the front section 5 of the slide-bar is advanced a step at each release of a division-piece. The added width of the division-pieces is also conveyed to the vice jaws and to the mould by gearing or escapement mechanism. The mould consists of top, bottom, and end pieces which open to admit the projecting parts of the division-pieces, and also to permit of ejection of the type. The division-pieces are provided with distributing-teeth similar to those of the matrices, but at a lower level, so that they are left behind by the second elevator and are engaged by a special carrier-bar which conveys them to their magazine. The Provisional Specifications state also that, as the width of the mould will be much greater than usual in type-casting machines, a metal-pump with a plunger of elliptical form is used, or a number of plungers geared together or operated independently may be employed. One of the Provisional Specifications states that the metal-pot mouthpiece is provided with holes of extended form to prevent their being covered by the ends of the division-pieces.
