Title: Improvements in and relating to apparatus for detecting and locating mineral deposits
IPC: G01S13/02
Filed: 1959-05-04
Abstract: 921,776. Radar. BEREND, J. R. May 4, 1959, No. 15195/59. Class 40 (7). The depth d of a geological discontinuity F, e.g. a mass of mineral ore, beneath the surface of the earth is determined by mounting a horizontally spaced radio transmitter T and receiver R above the surface of the earth and measuring the propagation time difference between waves arriving at the receiver R directly from the transmitter T and after reflection at the discontinuity F. In a pulse system the direct and indirect pulses are recorded on a moving magnetic or paper record strip, Fig. 3 (not shown), or displayed by deflection modulation of the linear or spiral timebase of a C.R.T., Figs. 4 and 5 (not shown), having a long after-glow screen which can be photographed. In a C.W. system employing sawtooth frequency modulation, the time difference is given by the beat frequency between the direct and indirect waves. The transmitter and receiver are tuned to a frequency, e.g. in the range 6 mc/s. to 700 kc/s., giving the maximum echo signal; such adjustment is facilitated if the transmitter is modulated at an audio frequency. The transmitting aerial may comprise a centre-fed horizontal wire of length 30 to 50 metres supported at a height of 50 cms. to 1 metre above the surface of the earth. The spacing between the transmitting and receiving aerials should be of the order of 2d.

Title: Improvements in and relating to typewriter-calculating machines controlling card-perforating machines
Filed: 1931-05-26
Abstract: 380,106. Selective punching- machines. ANSCHœTZ, R., 17, Hammerr÷dchen, Mehlis, Zella, Germany. May 26, 1931, No. 15359. [Class 31 (ii).] In a typewriter calculating-machine such as that described in Specification 363,049 wherein contacts are closed by the keys for controlling the selection and operation of punches in a card-punching machine, the contacts of the date and spacing keys 68, 69, 70, Fig. 2, are arranged at the keyboard itself and are operated directly by these keys. As shown in Fig. 1, the contacts 58, 59 controlling the numeral punches are operated from the cam-driven differential mechanism in the manner described in the prior Specification. Arranged on the bar 57 carrying these contacts are three further pairs of contacts 66, 67, Fig. 8, the upper blades of which are adapted to be depressed by the corresponding keys 68-70 through vertical rods 68aa-70aa. Normally depression of any of these three keys will cause operation of the spacing-mechanism of the card-punching machine. If however the case-shift key 109 is also depressed for printing the punctuation marks of the keys, an arm 115 carried by the key 109 depresses the lower spring blades 67 to prevent closure of any of the pairs of contacts 66, 67 and thus also the operation of the spacing-mechanism. Alternatively the key 109 may lock the lower ends of the rods 68aa-70aa which may be of a resilient character so that the keys 68-70 may be depressed without effect as regards closure of the contacts. The leads from the various contacts are connected to a plug 96 constructed as a pair of inner and outer commutator-like cylinders and insertible in a corresponding socket 79 on the punching- machine. To prevent closure of the numeral contacts 58, 59 when the totalizers are in a comma position, the totalizer-unlocking lever 29 is prevented from movement by a pin 29a so that the differential slide 17 is prevented from descending when the cam 9 rotates.

Title: Improvements in Continuous Process for the Manufacture of Esters.
IPC: C07C69/12
Filed: 1919-06-23
Abstract: 130,968. U.S. Industrial Alcohol Co., (Assignees of Backhaus, A. A.). Aug. 7, 1918, [Convention date]. Distilling-plant.-Esters are prepared in a continuous manner by feeding an alcohol, an organic acid, and a catalyst, either separately or mixed together, to a column still while distilling off the ester formed. The production of methyl acetate from methyl alcohol, dilute or glacial acetic acid, and sulphuric acid is described. Using the apparatus shown in Fig. 1, sulphuric acid, dilute acetic acid, and methyl alcohol are fed continuously in regulated amounts from tanks 8, 12, 18 respectively by pipes 7, 11, 15 to a column still 1 of ordinary construction; at the commencement sufficient methyl alcohol is run in to seal all the plates in the still. Vapours of methyl acetate and alcohol pass off by pipe 22 to a dephlegmator 23; condensed alcohol runs back from the dephlegmator to the still by pipe 24, while methyl acetate vapours pass off by pipe 25 to a second column still 26. From this still the methyl acetate vapours pass by pipe 27<1> to a dephlegmator 28, condensed alcohol flows back by pipe 29 to the top of still 26, while the methyl acetate vapours pass on to a condenser 31. A pipe 27 leads methyl alcohol from the lower part of still 26 to the still 1. Water and sulphuric acid flow from the bottom of still 1 by a pipe 20. The apparatus shown in Fig. 2 is similar in all respects except the feed device. Sulphuric acid, acetic acid (in this case glacial), and methyl alcohol are fed from tanks 42, 46, 50 respectively to a mixing-tank 35 which contains a rotary stirrer 36, and after undergoing partial reaction in the mixing-tank, the mixture is fed to the still by pipe 34; an initial charge of methyl alcohol as before is fed to the still by pipe 50<a>.

Abstract: 1,219,253. Selective printing. CREED & CO. Ltd. 26 March, 1969 [3 April, 1968], No. 15783/69. Heading B6F. [Also in Division H1] A hammer mechanism used either for impression or selection has the duration of the impact shortened by using a lost motion connection between the hammer and its actuator. The hammer actuator has its motion reversed whilst the hammer continues to move forward under its own momentum, and when the amount of lost motion in the connection has been taken up, collision between the hammer and its actuator causes a rapid and sudden withdrawal of the hammer. Hammer impression.-In Figs. 1 and (3), the hammer 1 is mounted on a pair of beryllium springs 7 and the L-shaped actuator 2 is pivoted at 9 to the base 6. Energization of the electromagnet 3 attracts the armature 10 attached to the actuator, thereby causing it to pivot and propel the hammer towards the continuously moving type 11. The actuator comes into contact with a fixed rubber cushion 4, from which it rebounds. Collision then occurs between faces F 1  and F 2  causing the hammer 1 to have a sudden reversal of movement, thereby shortening the duration of impact. In (Fig. 3), the rubber cushion 4 is mounted for adjustment between the poles of the electromagnet 3. The position of the actuator with respect to the electromagnet is adjusted with a screw 13 in the base 6. Type lever selection.-In Fig. 4, the hammer mechanism utilized for selecting the type levers mounted on a continuously rotating basket comprises an electromagnet housing 20 containing a coil 21, a guidance sleeve 31 and an actuator 22 composed of a lower portion 23 and a terminal portion 24. Portion 24 is enclosed within the cushion housing 25 containing a rubber cushion 26. A hammer 28 is retained in its neutral position in contact at 27 with the actuator 22 by a spring 29. Energization of the electromagnet causes the actuator to move upwards until it comes into contact with the rubber cushion 26, whereafter the hammer 28 continues to move under its own momentum. The actuator rebounds so that faces F 1  and F 2  collide, causing the hammer to have a sudden reversal of movement.

Title: A process for reactivating a spent refining adsorbent
IPC: B01J20/34
Filed: 1947-06-16
Abstract: <PICT:0636752/III/1> A spent refining adsorbent such as clay silica gel, or bauxite, used for decolourizing and/or neutralizing mineral oils and fats and containing organic contaminants and a minor amount of water is reactivated by extracting the adsorbent with a partially water miscible polar liquid, e.g. alcohols, aldehydes, ketones, particularly those with 4-7 carbon atoms, ethers and oxygenated organic compounds or mixtures of these with polar and/or non-polar substances such as aromatic hydrocarbons, chloroform or carbon tetrachloride, to form an extract of the organic contaminants and water; separating the extract from the adsorbent; mixing the extract with a non-polar liquid, e.g. aliphatic hydrocarbons preferably having a boiling point 30 DEG  C. or more above that of the polar liquid, miscible with the polar liquid to form an extract phase comprising polar and non-polar liquids and a water phase; separating the two phases; and recovering the polar liquid from the extract phase for recycling to further extraction.  An oil or naphtha slurry of spent clay is filtered in 2, de-oiled by washing with naphtha (b.pt. 40-100 DEG  C.) from tank 5 and dried by blowing with steam or hydrocarbon gas, while the naphtha and oil are separated in still 4 and the naphtha is returned to tank 5 through condenser 10.  The clay is transferred to batch or continuous extractor 15 and contacted at normal or superatmospheric temperature and/or pressure with methyl-ethyl ketone from tank 16, and the extract is passed to separator 19.  The clay is vacuum distilled and/or steamed to remove remaining ketone which also passes to separator 19 through condenser 21, and the clay is then further steamed to restore its activity.  A high boiling naphtha fraction (b.pt. 120-160 DEG  C.) is added from tank 25 to the extract in separator 19 causing the separation of a water phase containing little ketone which is discharged at 27, and a ketone-naphtha-organic matter extract phase which is distilled in still 29 to separate organic pitch from the ketone-naphtha mixture which is itself separated in still 33; the ketone is recycled through condenser 35 to tank 16 and the naphtha is recycled to tank 25.  The first washing may be omitted and spent clay charged direct to extractor 15.  An alternative apparatus is described wherein the de-oiling, extraction, and separation of ketone, naphtha, and water are all carried out in the extractor.
