Patent GB-137835-A (GB)
Abstract: 137,835. BollÚe, A. Jan, 11, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Rings.-A split piston-ring is formed from a blank which is only sufficiently larger than the cylinder bore to allow for the metal removed in making the split. The ring after splitting is expanded on a templet and heated in the expanded state, so that it retains its expanded form after cooling. The heating may be effected in a furnace or by plunging into molten salt &c., or the ring may be heated by a blowpipe while being rotated in a lathe. The shape of the templet is determined by expanding the ring under the action of radial forces. the total of which equals the pressure which the ring is required to exert on the cylinder walls. As shown in Fig. 2, the apparatus may consist of a table with pulleys over which pass weighted cords 5, secured to hooks 6, which engage the piston ring.

Title: Improvements in the manufacture and production of acetaldehyde
Filed: 1935-05-10
Abstract: In the production of acetaldehyde from acetylene and steam by means of a cadmium phosphate catalyst, a part of the cadmium phosphate is replaced by an alkaline earth phosphate.  The reaction may be effected at 300--450 DEG  C., but at the beginning a lower temperature such as 250--300 DEG  C. may be employed which is gradually increased.  The acetylene may be pure or dilute.  In examples there are employed: (1) cadmium phosphate precipitated on calcium phosphate; (2) cadmium and calcium phosphates precipitated from the mixed nitrates by tri-ammonium phosphate; and (3) cadmium and strontium phosphates precipitated from the mixed nitrates by trisodium phosphate.  The proportions mentioned are from 2 to 90 per cent of alkaline earth phosphate, the rest being cadmium phosphate. Preferably catalysts which give X-ray patterns similar to those of apatite are used.  These are obtained when the phosphates are precipitated while heating or when the precipitates are heated for a short time above 70 DEG  C.ALSO:Catalysts for the production of acetaldehyde from acetylene and steam consist of mixtures of cadmium and alkaline earth phosphates; the alkaline earth phosphate may be from 2 to 90 per cent of the mixture.

Title: Method of seismic prospecting
IPC: G01V1/00
Filed: 1954-05-12
Abstract: 761,603. Geophysical echo-sounding. SEISMOGRAPH SERVICE CORPORATION. May 12, 1954 [June 19, 1953], No. 13894/54. Class 118 (2). A method of making records representative of the profile of subsurface strata disposed below the earth's surface comprises generating seismic waves in the earth at a plurality of different shot points over said strata, producing separate reproducible records on a per shot basis of the seismic wave reflections and refractions received at a plurality of detecting positions, separately reproducing the individual reproducible records produced at each of the detecting positions to translate the same into visual records, correcting each of the said visual records to the same datum plane during reproduction of the reproducible records, and assembling the said visual records to produce a final record having aligned points representing the subsurface strata. A plurality of shots are fired at various depths in spaced-apart bore-holes (Fig. 1, not shown) and the signals from an array of detectors placed on the earth's surface are recorded on a magnetic recorder. The detectors used for any particular shot are arranged colinear with the bore-hole in question but at different horizontal distances therefrom and at different heights due to weathering layer topography. An electrical signal of the firing of the shot and the up-hole travel time are recorded also (Fig. 2, not shown). A visual oscillographic recorder is connected in parallel with the magnetic recorder to enable estimation of corrections for weathering layer and elevational differences to be later applied to the magnetic recordings. The magnetic recordings are played back using a reproducer having separately adjustable heads for each track (Fig. 3, not shown). A screw adjustment is set to correct for the weathering and elevational differences and displaces its respective head relatively along the tape. This effectively reduces all the outputs to a common datum level. To correct for spread (horizontal distances between detecting geophones and the shot) a camshaft carries a cam for each head and is driven from the tape drive motor since this correction will vary with depth of the reflecting layer, being negligible for the longer echo times. The outputs from the magnetic reproducer may be individually fed to an oscillograph recorder or the corrected traces from any one shot may be mixed and then visually recorded. The corrected traces are representative of those that would have been recorded had the shot been located at the datum level and the geophones been superimposed upon the shot point. Uncorrected and corrected traces for one shot point are indicated in Figs. 4 and 5 respectively (not shown). By arranging the corrected traces of the several shots such that the up-hole signals are aligned a composite record in well log form is obtained (Fig. 6) in which the tilt from the vertical of the aligned reflected waves is a function of the tilt of the subsurface strata. Specification 760,987 is referred to.
