Title: Improvements to soot blowers
IPC: F28G3/16
Filed: 1935-01-30
Abstract: 434,683. Soot blowers. BABCOCK & WILCOX, Ltd., Babcock House, Farringdon Street, London.-(Assignees of Deutsche Babcock & Wilcox Dampfkessel-Werke Akt.- Ges. ; Oberhausen, Rhineland, Germany) Jan. 30, 1935, No. 3098. Convention date, March 29, 1934. [Class 99 (ii)] In a soot blower for a boiler, a nozzle 30 located on the end of a blower tube 11 is adapted to be retracted into the wall box 43 of the boiler and to be advanced into operative position by a chainwheel 5 which is geared to a pinion 10 formed with an internally-screwthreaded part to engage a screwthread on the blower tube, a member 44 secured to the wall box being provided with a tooth 15 to coact either with a longitudinal groove 16 on the blower tube to prevent rotation of the latter during its advancing and retracting movements or with an annular groove 19 thereon in its advanced position. Cleansing fluid is supplied to the blower through pipes 7, 34, the supply being controlled by a valve 33 which is opened and closed by a lever 26 under the action of a cam 24 on a collar 17 secured to the end of the blower tube, the cam 24 coacting with the lever 26 when the blower is advanced and the collar 17 abuts against the hub 18 of the pinion 10. Fig. 3 shows a detent mechanism which after a complete rotation of the blower tube locks it against rotation but permits its retraction and which comprises two spring- pressed pawls 39, 48 pivoted in blocks 36, 50 mounted, the latter slidably, in a groove of the member 44. When the blower tube is advanced a lug 40 on the collar 17 bears against the pawl 39 and pushes it inwardly to permit counterclockwise rotation thereof. Shortly before a complete rotation of the blower tube is effected however the lug first rides over the pawl 48 and presses it inwardly and then strikes the face of the pawl 39 and pushes it to the left with the block 50 ; at the same time the lug 40 releases the pawl 48 which moves forward behind the lug. The said lug is now held between the two pawls and further rotation of the blower is prevented, but since the tooth 15 is again in alignment with the groove 16 the blower tube may be retracted by rotation of the chainwheel in the opposite direction.

Title: Film badge system of radiation dosage determination
IPC: G01T1/08
Filed: 1964-01-27
Abstract: 1,044,443. Dosimeters. UNITED STATES ATOMIC ENERGY COMMISSION. Jan. 27, 1964 [March 11, 1963], No. 3332/64. Heading H5R. [Also in Division E2A] A dosimeter film badge has a filter system including a tantalum filter, an iron filter, a plastic filter and an open window. The badge is designed to measure the radiation dosage received from a mixed radiation field consisting of uranium-derived beta particles, γ rays of energies greater than 50 keV. and either γ or X-rays at energies less than 50 keV., according to a number of conditions. The badge body, of plastics material, has a metal clip 11 attached to the back 10, which is moulded with an open window 16 and recesses designed to receive a latching mechanism 12, a lead plate 20 and the tantalum 21 and iron 22 filters. The plastic filter comprises the area between the recess 15 and the open window 16. The front 70 of the badge, also of moulded plastics, is cemented to the back 10 and has a recess 71 for receiving an identification label. A plastic sheet covers the filters, occludes dust and filters out soft X-rays generated in the elements 20, 21, 22. The photographic plate 40 is wrapped in paper to exclude light. A plastics insert 50 slides snugly within the raised rim 19 of back 10 and holds between itself and the plate an arrangement of filter elements (Fig. 2, not shown) to correspond with the arrangement on the other side of the plate, so that the same radiation intensities reach the plate 40 from both sides of the badge. Extra filters may be provided for the measurement of high energy neutron and γ-radiation. In the measurement of radiation doses received, the photographic plate 40 is removed from the badge and the density of exposure measured for each area of the film corresponding to the particular filter-tantalum, iron, plastic or open window. The filters are arranged to have different attenuations with respect to individual parts of the radiation field considered. The conditions for the filters specify that the tantalum filter blocks out all beta rays and X- rays, that beta-radiation is attenuated equally by the iron and plastic filters and that γ-rays of energy > 50 keV. are attenuated equally by the iron, plastic and open window filters, this being arranged by having a particular thickness for each filter. Using the calibration graphs of exposure densities against standard radiation doses in milliroentgens (Figs. 4-7, not shown) for the filters with each type of radiation, and the measurements of exposure density on the film, values of doses received from different sources can be measured by applying a procedure described in the Specification. This procedure involves applying the readings of exposure (optical) density obtained using a Bechman densitometer, for example, to a number of equations involving each filter and using the filter conditions. Examples of the application of the procedure, for different sources, are given.

Title: Improvements relating to processes for the fractional decomposition of hydrocarbon mixtures
IPC: C10G21/00
Filed: 1937-02-05
Abstract: Mineral oils are separated into fractions by flowing the oil on to a body of a solvent of lower specific gravity than the oil, and after standing, drawing off layer fractions which contain the desired final oil in admixture with lighter oils and solvent, and distilling these fractions to remove the solvent and the lighter oils at a temperature lower than the <PICT:0474508/III/1> boiling range of the desired oil which is obtained as residue.  A crude mineral oil is fed from a tank b to a column c about half full of benzine.  The oil is distributed uniformly through a tubular cross h.  After standing, insoluble matter is removed through a cock g and three fractions are drawn off through the 3rd, 6th, and 8th valves f.  These fractions are freed from solvent and then distilled at 200 to 215 DEG  C. under a reduced pressure of 50 to 60 mm. to remove light oils, leaving three lubricating-oil fractions.  Specification 460,906 is referred to.

Meters.-Substation apparatus includes a manually-operated plunger e for closing the transmitter circuit m and actuating a counter by means of an arm g which is swung laterally upon dialling. Raising of the switchhook b allows upward movement of a lever b<1> and movement to the left (Fig. 2) of a horizontal bar c<1> which bears against the oblique face b<5> of the lever b<1>. Spring detents f, d are thus released. A finger h<1> on the dial h bears against a curved lug h<2> on a lever h<3>, and upon dialling, the lever h<3> swings laterally and brings the arm g on the plunger e into alignment with a yoke g<1> carrying the counter actuating pawls k<2>, k<3>, k<4>. The arm g is locked in this position by the detent f. The plunger e is moved to the right (Fig. 2) to close the transmitter circuit and is held by the engagement of the detent d with a notch d<1>, and the yoke g<1> is rocked by the arm g to advance the counter. The pawls k<2>, k<3>, k<4> are staggered on a common shaft carried by the yoke g<1>. transfer being of the deep notch type. At a called substation, the transmitter circuit is closed without actuation of the counter. A stop n on the plunger e is provided which moves into the path of the arm g to prevent an unrecorded call being made. The number of calls made is seen through a window p.
