Title: Improvements in Apparatus for Cleaning the Smoke Tubes of Steam Generators.
Inventor: PARRY CHARLES PERCY
IPC: F28G3/16
Filed: 1918-08-23
Abstract: 131,712. Parry, C. P. Aug. 23, 1918. Cleaning, fluid-pressure processes for.-An apparatus for cleaning smoke tubes of boilers of the kind described in Specification 12829/15 is constructed with a carrier 1 provided with a series of guide vanes which direct a series of steam jets in a reverse direction, in combination with a pressurereducing nozzle of De Laval type through which the steam passes on its way to the vanes. The device is rotated and moved longitudinally so that the jets cover the whole of the area of the tubes. Improved constructions of nozzles, balanced valve, and means for operating the carrier are described. The carrier 1 is adapted to be moved in a smoke-tube 4, or a specially constructed tube, by means of an operating-rod 7 which extends right through the apparatus, and steam is supplied from a pipe 5<1>, Fig. 1, through a valve 11, to the tube 4. The steam is passed to nozzles 3<a>, 3<b>, 3<c>, 3<d> formed in the carrier 1, when the carrier has been moved to its operative position, shown in Figs. 1 and 4, the valve 11 being opened by means of a rotating sleeve 6, which passes through the smoke-box casing 8, and is operated by a hand-wheel 38 which is provided with a locking-pin for securing the rod 7 when the carrier 1 is in its retracted position, and the valve is closed. In opening the valve 11, the sleeve 6 positively moves a balancing, or overbalancing piston 12, attached to the valve, and when the sleeve is retracted, the valve closes under steam pressure. Piston valves may displace the lift valve shown. In the operative position shown in Fig. 4, the nozzle 2 has a valvelike part 15 which fits tightly in the end 16 of tube 4, and compels the steam to pass entirely through the nozzle 2. The nozzles 3<a>, 3<b>, and 3<c>, 3<d>, are formed as shown in Fig. 6, and lining members 19, 20 screwed to the carrier 1, by reducing the diameter of the carrier, cause the nozzles 3<c>, 3<d>, to receive sufficient share of the steam. The nozzles 9<a>, 3<b> are formed by milling transverse slots 17 and fitting into these the heade of the liners 19, 20 which are recessed as shown at 3<a>, 3<b>, and act in conjunction with surfaces 22, 23 to direct the sprays. The nozzles 3<c>, 3<d> are formed in a head-piece 24 connected by screws and a cross-pin 25 to the carrier 1. When the valve 11 closes, it forces back the rod 7 with it, or conversely the rod 7 when withdrawn may operate to close the valve. Instead of using four nozzles as shown, the nozzles 3<a>, 3<b> may be dispensed with, or additional ones be. tween these and the end ones may be employed.

Title: Process for the production of beryllium alloys of the heavy metals
IPC: C22C28/00
Filed: 1932-05-12
Abstract: Alloys of beryllium with heavy metals, for example copper, nickel or iron, are produced by the thermal reduction of beryllium compounds in the molten heavy metal by means of magnesium or a magnesium alloy, for example an alloy containing 40-60 per cent of aluminium.  A mixture of the beryllium compound and reducing agent, preferably briquetted, is introduced into the heavy metal, or the beryllium compound is stirred into a melt consisting of an alloy of the heavy metal and magnesium, preferably under a flux. Excess of the reducing agent is removed by heating the melt to vaporize the magnesium.  The reduction may take place in an atmosphere of hydrogen.

Title: The para-amino salicylic acid derivative of 2-pyridyl-(4)-1:3:4-oxadiazolone-(5) and processes of preparing same
IPC: C07D413/04
Filed: 1954-05-11
Abstract: The invention comprises the para-aminosalicylic acid derivative of 2-pyridyl-(4)-1,3,4-oxadiazolone-(5) and its preparation by reacting an acid-addition salt of 2-pyridyl-(4)-1,3,4-oxadiazolone-(5) with para-aminosalicylic acid (PAS) or an alkali metal, ammonium or alkaline earth metal salt thereof.  Preferably an alkali metal salt of PAS and the hydrochloride of the oxadiazolone are reacted in aqueous solution. In examples, the compound of the invention is prepared (1) by reacting PAS with the oxadiazolone in hydrochloric acid, and (2) by reacting the sodium salt of PAS with the oxadiazolone hydrochloride in water.  2-Pyridyl - (4) - 1,3,4 - oxadiazolone - (5) may be prepared by reacting isonicotinic acid hydrazide (INH) or an acid-addition salt thereof with phosgene, the free oxadiazolone being liberated, if desired, from the hydrochloride first formed by neutralization with an alkaline substance.  This reaction is preferably effected without pressure in a solvent at a temperature between 0 DEG  C. and the boiling-point of the solvent, advantageously in an inert organic solvent such as dioxan when INH itself is used but in water or an aqueous organic solvent when a salt of INH is used.  Examples of the preparation of 2 - pyridyl - (4) - 1,3,4 - oxidiazolone - (5) are also given.  Specification 729,891 is referred to.

Title: Improvements in the preparation of foodstuffs from dates
IPC: A23L19/00
Filed: 1937-05-18
Abstract: A food preparation is obtained from dates by reducing the dates to a paste or, by addition of water or other liquid, to liquid form, drying in a vacuum desiccator heated to a temperature not exceeding 50 DEG  C. and mixing the date powder obtained with a preservative, e.g. calcined magnesia, and with alimentary substances, e.g. powdered cacao nut, rice powder, fecula or starch from potatoes or groats, powdered sugar or tapioca or manioc flour.  Vanilla, orange or lemon extract or other flavouring substance may also be added.  The dates may be freed from the stones and spread in the form of a slightly tacky paste in a layer of about 2/5 in. thickness on one or more plates in the vacuum desiccator in which they may be kept 3-7 hours. In another form, the paste is diluted with water &c. to a liquid which is introduced into the desiccator in one or more streams which impinge on a disc rotating at high speed, e.g. 600 r.p.m., the liquid being projected on to the heated inner wall of the desiccator.  In a further form, the dates are, prior to desiccation, soaked in water &c. to make them swell, freed from the stones and crushed to a paste which is then diluted to liquid form.  Examples of the proportions of the ingredients used in making the preparation are given.

Gyroscopic compasses.-In compasses having a gravity-controlled gyroscope with a substantially vertical axis, the tilting of which orients a rotatably mounted card or its equivalent, the card &c. and gyroscope are independently mounted, and interconnecting means are provided between them. The compass preferably comprises two gyroscopes 1, 2 rotating in opposite directions, their casings being secured to frames 13, 15 respectively, which are pendulously mounted on normally coincident axes 8-9, 16-17 in gimbal rings 10, 8 carried by a common horizontal axis 11 in a pedestal 50. The frame 15 carries a ring 20 bearing a lubber-line or other reference marks, and a card 24 having a central boss 25 mounted on antifriction bearings 26. Interconnecting means between the card 24 and the gyroscope 1 are. provided by a slot 27 in the under surface of the boss 25, and a projection 30 on the casing of the gyroscope 1 projecting into the slot. The rotation of the earth causes the gyroscopes to precess in opposite directions, so that the projection 30 travels along the slot and orients the card 24. The gyroscopes may be connected by energyabsorbing means to damp oscillations. As shown, the cylinder 42 of a dash-pot is linked to the casing of the gyroscope 2, and the piston 41 thereof is linked to the casing of the gyroscope 1. In a modification, both gyroscopes may rotate in the same direction, one of them being mounted like an inverted pendulum.
