Patent GB-1099138-A (GB)
Title: Electrical prospecting
Inventor: RUNGE RICHARD JOHN
IPC: G01V3/20
Filed: 1966-03-28
Abstract: 1,099,138. Borehole logging. CHEVRON RESEARCH CO. March 28, 1966, No. 13675/66. Heading G1N. To determine the lateral distance from a well bore of a salt dome or other highly resistive body, by measuring the resistivity of the surrounding formations, the average resistivity over a given long depth is estimated by making a plurality of measurements with short spaced potential electrodes, and comparing the estimated average resistivity with that actually measured by longspaced electrodes; a substantial difference indicating the presence of a salt dome. In practice the estimated resistivity is derived as the reciprocal of the depth average conductivity. In Fig. 1 the short spaced resistivity measurement is plotted by a pen 41 on a chart advancing with the depth of the "sonde". The signal is also inverted by an analogue divider 59 and fed to an integrator 60. At the same time an optical follower 62 provides a signal from the chart corresponding to the bottom of the long-spaced measurement which is subtracted at the integrator to provide a running average. The output of the integrator is inverted at 39 to drive pen 33 recording the estimated effective average resistivity for comparison with the actual long-spaced measured resistivity recorded by pen 71. Since greater accuracy is obtained when the transverse distance of the salt-dome is about the same as the distance between the long-spaced electrodes, a plurality of long-spaced measurements may be made at e.g. 200, 500, and 1, 000 feet spacing. Such an arrangement is described with reference to Fig. 3 (not shown) in which the short-spaced signal is recorded on a magnetic drum to provide bottom signals for subtraction at the integrators, instead of using optical followers on the short-spaced graph, as in Fig. 1. A digital signal processing arrangement may be used, and this is illustrated in a block diagram Fig. 4 (not shown).

Title: Improvements relating to presses for cutting blanks from sheet metal and for similarpurposes
IPC: B21D28/08
Filed: 1923-05-24
Abstract: 216,336. Griffiths, H. A., and Griffiths, R. H. May 24, 1923. Metal-sheet feeds; spacing- racks and like bars.-In semiautomatic feeding-mechanism of the intermittently advanced carrier type for presses for cutting blanks from sheet metal, the work grip or carrier h slides on a tubular rod d mounted on the usual transverse slide. A positioning bar b is fitted with abutment pieces f for engagement by pawls l on the carrier. The pawls are lifted momentarily after each punching operation by a wire m attached to a moving part of the machine, thus allowing the carrier to be moved along the rod by hand until the pawls re-engage. One pawl acts while the metal sheet is fed in one direction, while the other acts on the reverse movement. A lever n can be operated to disengage the pawls independently of the wire m when desired. A roller p on the carrier engages the underside of the bar band prevents bending of the bar under the action of the pawls. A roller engaging a slot in the member e prevents rocking of the carrier on the rod d.

Title: Improvements relating to hydraulic control valves
IPC: F15B13/04
Filed: 1937-05-18
Abstract: 495,422. Hydraulic control valves. SULLIVAN MACHINERY CO. May 18, 1937, No. 13804. Convention date, May 15, 1936. [Classes 69 (ii) and 135] A hydraulic control valve for controlling the flow of liquid from a pump and reservoir circuit 21, 22 to the power cylinders 15 of a drill feeding mechanism 14, 12 in which different rates of feed are required for forward and retraction operations comprises a hollow piston member 46 in a casing 26 with a pressure fluid supply inlet 37, an exhaust outlet 42, and connections 40, 41 for pipes 20, 19 leading to the opposite ends of the cylinders 15 respectively. The valve piston 46 is provided with ports 57, 58 for controlling the exhaust from either of ports 29a or 30a at the connections 40, 41 respectively according to whether it is moved to the left or right from its neutral position shown, and annular recesses 51, 52 for the passage of the pressure fluid to the other port. Rotation of the piston 46 will increase or decrease the communication between the ports 57, 58 and 29a or 30a to regulate the exhaust of the pressure liquid to enable the rate of the feeding operation to be adjusted. In the neutral position of the valve, as shown in Fig. 2, the inlet 37 and exhaust 42 are in communication so that the pump 21 is relieved of load, and the fluid in both ends of the cylinders 15 is entrapped so that the pistons 17 are held positively against movement. Both the rotary and sliding movements of the valve 46 are effected by a single control handle 64 which is pivoted at 63 to the valve spindle and at 65 to a link 66 mounted on a rotatable ring 69 on the valve casing. The ring 69 has a lug 77 which cooperates with a pin (not shown) on an adjustable stop ring 72 which can be adjusted to enable a certain condition of feed, for example, minimum feed, to be repeated.

Title: Improvements in or relating to the ozonization of oils
IPC: A23D9/02
Filed: 1928-05-10
Abstract: 321,633. McKee, J. May 10, 1928. Medicines for internal and external use.-Oils containing large proportions of assimilable ozone, for internal or external use, are obtained by heating fish, animal, or vegetable oils to remove taste and odour components and to raise the S.G. to 0.970-0.980, and then ozonizing. Oils specified as treated are lard oil, tallow oil, salmon oil, sardine oil, castor oil, cottonseed oil, rape seed oil, corn oil, and linseed oil. Up to 15 per cent by weight of ozone may be incorporated. For example, linseed oil or fish oil is heated in a still 10 to 560‹ F. for about 0.5-2 hours under pressure reduced to 10-15 m.m., by a pump 23. The temperature is then reduced to 150‹ F. and a stream of ozone or ozonized -air passed through until the required percentage is absorbed. The acids, &c. condensed by the condenser 18 and collected in a trap 19 and storage vessel 25 may, after or without any desired treatment, be re-incorporated with the oil, preferably before ozonization. Tasteless and odourless castor oil retaining its cathartic powers may thus be obtained by treating the condensate with steam at 350‹ F. until the taste and odour-producing substances are removed, and then incorporating in the ozonated castor oil in the tank 10. Linseed and like oils may initially be partially oxidized, as by blowing in air at 130‹ F. until the S.G. is about 0.943.

Title: Method of seismic recording
IPC: G01V1/24
Filed: 1954-05-12
Abstract: 760,987. Geophysical echo-sounding. SEISMOGRAPH SERVICE CORPORATION. May 12, 1954 [June 19, 1953], No. 13895/54. Drawings to Specification. Class 118 (2). Apparatus for seimic prospecting utilizing seismic waves generated at a plurality of elevations above a subsurface strata at a particular position, comprises means for producing individual reproducible records, for each elevation, of waves received at a detection point spaced from the position, means for correcting said individual records for observed vertical time differences due to the different elevations at which the waves are generated, thereby to bring them to a common level or datum plane, and means for algebraically combining said individual corrected records to produce a master or composite record. Two shots are fired, for example, at depths of 50 feet and 100 feet in a bore hole and the seismic echoes are picked up by several geophones at a distant point (Fig. 2, not shown). A further detector situated close to the top of the bore hole picks up the direct vertical waves. Traces are recorded from each of the distant geophones, both on magnetic tape and on an oscillograph (Figs. 4 and 5, not shown). One of these traces also carries the " up-hole " or direct vertical pulse and another trace also records the actual firing pulse, so that the uphole travel time for each shot can be easily determined by comparison of these pulses on the appropriate oscillograms. The magnetic tape is played back on a reproducer (Fig. 3, not shown) having separate heads to pick up simultaneously, the traces made by the various geophones, a complete set of heads being provided for each shot fired (in this example, two). The sets of heads are spaced apart a distance corresponding to the interval between firing of the shots and manual fine adjustment means is provided so that the heads may be further set in accordance with the vertical time difference determined from the oscillograph record as above This adjustment brings the outputs from the various traces to a common vertical datum level; for convenience this may be the level of the topmost shot. The outputs from each geophone can then be added algebraically in pairs in a mixing network and the composite traces recorded by an oscillograph (Fig. 7, not shown). It is stated that the vertical signal to horizontal signal ratio is thereby increased and the effects of extraneous vibrations attenuated. Specification 761,603 is referred to.
