Title: Improvements in or relating to coating metals
IPC: C23C22/74
Filed: 1960-07-11
Abstract: Metals are rendered corrosion resistant by coating the metal surface with an aqueous solution of one or more water-soluble mono-organosilanes of the general formula RSi(OR1)3 where R is an alkyl radical containing less than 6 carbon atoms, a monocyclic aryl radical or an alkenyl radical containing less than 6 carbon atoms, and each R1 is <FORM:0893397/III/1> or -CH2,CH2 (OCH2CH2)n OH where n is greater than 1, or a water soluble partial hydrolysate of such a silane or silanes and curing the coating by heating at a temperature of at least 100 DEG  C.  Specified metals treated are aluminium, zinc, magnesium, copper and steel.  In the case of aluminium the silane is preferably cured at a temperature of 250 DEG  to 600 DEG C.  The aqueous solutions preferably contain 0,5-60% of the mono-organo-silane and may have wetting agents added thereto. The aqueous solution is applied by dipping, spraying, brushing or flowing to a metal which may be pretreated by steel-wooling, degreasing with solvents, pickling or merely washing.  The coated metals may be further coated with wire-enamels, lacquers or other surface coatings. Specifications 825,551 and 850,419 are referred to.ALSO:Aqueous solutions used in coating metals contain one or more water-soluble mono-organosilanes of the general formula RSi(OR1)3 where R is an alkyl radical containing less than 6 carbon atoms, a monocyclic aryl radical or an alkenyl radical containing less than 6 carbon atoms and each R1 is -CH2.CH2.OCH3, -CH2.CH.2OCH2.CH3, -CH2.CH2.OCH2.CH2.OCH3, -CH2.CH2OH, or -CH2.CH2(OCH2.CH2)nOH where n is greater than 1, or a water soluble partial hydrolysate of such silane or silanes.

Title: Acoustic well logging sondes
IPC: G01V1/52
Filed: 1972-05-24
Abstract: 1399735 Acoustic well-logging SCHLUMBER INLAND SERVICES Inc 24 May 1972 [24 May 1971 (3)] 24370/72 Heading H4D An acoustic well-logging sonde having a body of generally cylindrical form is characterized in that at least one transmitting and/or receiving transducer comprises one or more transducing elements the active face or faces of which lies or lie on a convex surface so that the overall sensitivity of the transducer is substantially uniform over a range of angles in a plane containing the sonde longitudinal axis. In the Fig. 2 embodiment the sonde includes two transmitting (TX) transducers 36, 37 in the sonde body 40 and two receiving (RX) transducers 66, 68 on a pivoted, wheeled measuring pad 42 which is spring-urged towards the borehole wall. The sonde body is urged towards the wall by sprung arms 78, 80 but is held slightly away from the wall by sprung wheels 94, 96. The pad, arms and wheels can be retracted by hydraulic actuators when the sonde is being lowered. The transducers may be piezoelectric or magnetostrictive cylinders with their axes horizontal, spherical, of disc or torpid sector form, or comprise a group of strip-form elements. Their directivity patterns are such that their sensitivity, over a range of incidence angle α (Fig. 3) for which refracted waves will be detected, is substantially constant and such that the waves are received at an RX transducer substantially in phase irrespective of the exact point of emission on the TX transducer surface or exact point of incidence on the RX transducer surface. To prevent acoustic vibrations other than desired refractions from reaching the RX transducers, or at least to attenuate or retard undesired vibrations, the sonde body 40 and measuring pad 42 are each constructed as a mechanical low-pass filter comprising flexibly linked masses (details given, Figs. 4, 6, 7, 8, none shown) and include apertures which lengthen the vibration travel path. In addition the wheels 94, 96 and pad wheels 62, 64 are provided with shock-absorbing tyres, and the transducers are arranged in recesses and spaced from the recess walls by greater than a half wavelength of desired acoustic waves in fluid contained by the borehole. The RX transducer outputs are electrically filtered to suppress undesired signals. The sonde may be used to obtain a differential measurement of the wave propagation times from one TX to two RX transducers. All the TX and RX transducers may be mounted on a common pad instead of as shown.

Title: Improvements relating to rotors for multi-stage axial-flow compressors and the like
IPC: F01D5/06

Abstract: 864,440. Axial-flow compressor and like rotors. DAIMLER-BENZ A.G. July 17, 1959 [July 17, 1958], No. 24644/59. Class 110 (3). A built-up rotor for a multi-stage axial-flow compressor or like fluid-flow machine comprises a series of discs 11 which carry the blades 15, each disc having axially - directed ring portions 12, 13 which are secured to one another by induction brazing or hard soldering, preferably effected under a protective gas, the ring portions, which preferably act as centring-means being so designed and arranged that the brazed or soldered joints are not subject to tensile force. The ring portions 12, 13 are formed with radially-extending surfaces 16 and axiallyextending surfaces 17, 18, the surfaces 16 of adjacent discs abutting so as to space the rotor discs axially and the surfaces 17, 18 interengaging so as to centre the discs. The axially. extending surface 18 of the ring portion 13 at the downstream side of the rotor disc faces radially inwardly, while the axially-extending surface 17 of the ring portion 12 at the upstream side of the rotor disc faces radially outwardly and it is this disposition which ensures that the joints are not subject to tensile stress. It is stated that the centring surfaces of each pair of ring portions are subject to compressive stress since a downstream stage always develops greater centrifugal force than an upstream stage.

Title: Improvements in the production of pulp from highly resinous woods
IPC: D21B1/16
Filed: 1937-09-20
Abstract: In grinding highly resinous woods such as pinewood, water-soluble barium compounds or mixtures thereof are added to the wood or pulp water during or after the grinding operation to convert the resin into a difficulty soluble non-adhesive barium salt.  Between ,1 and 1 Kg. per cubic metre of wood is added to the water such that a pH value of 7 is not exceeded and the water should not be allowed to fall below 50 DEG  C.  The resinate of barium remains in the pulp as a filler and when acids are added it is not reconverted into free resin.  Known dispersion agents such as fat, alcohol sulphonates may be added.  Soda or soda lye may first be added at the grinder to saponify the resin and then barium chloride, preferably in solution, is added at a later stage to convert the sodium of the resin into a barium salt.  Since pulp water is usually acid, with a pH value between 4 and 5, produced by organic acids such as formic acid or acetic acid, the soluble barium salts may be produced by adding barium carbonate to the water whereby the resin is precipitated.

Title: Improvements in or relating to the extraction of organic materials
IPC: A23F5/26
Filed: 1934-09-06
Abstract: Organic material such as coffee, tea, fruits, vegetables, drugs, and medicinal plants is prepared for extraction by first heating in the dry state, treating with a liquid, preferably an extraction agent, in such quantity that the mass remains substantially dry, and finally heating for a long time, for example several hours.  Coffee powder is heated to 40-50 DEG  C., by feeding through a heated pipe to a receptacle.  Cold water is now distributed over the coffee by a sieve or distributing plate, for example, 6 litres of water are added to 9 kg. of water.  The coffee layer is left undisturbed and its temperature is kept at 50-80 DEG  C., by means of a steam-jacket. After say 5 hours, the extraction can be effected in the same receptacle.  Alternatively the coffee is heated, the calculated amount of water added, heating continued to about 80 DEG  C., the container then closed, placed in insulating packing and left for several hours. Extraction agents other than water may be used but the pre-heating and final heating temperatures should be below their boiling points.
