Title: Indicators for radio navigation
IPC: G01S1/02
Filed: 1939-09-19
Abstract: 532,654. Directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd. Sept. 19, 1939, No. 26157. Convention date, Oct. 12, 1938. [Class 40 (v)] The pointer of an indicator for use with a radio compass is adjustably damped, either automatically or by hand, according to prevailing signal and weather conditions, and during the interval between successive signals of the AN type. As shown in Fig. 1, the needle 2 is subject to a magnetic brake applied to a disc 4 by magnets 5, 6, which are energized from a source 7 through a variable resistance 8. In Fig. 2, the degree of braking is controlled by the incoming signal through a relay 22 which opens the normally-closed contact 23, and closes the contact 231 to apply a stronger magnetizing current to the magnet 5 during the interval between consecutive signals. Alternatively a vibrating reed of the buzzer type is made to strike against the disc 4, or against a plate associated with it, so as to apply a frictional brake. This can be varied by causing the incoming signals to operate a valve relay which energizes an electro-magnet to modify the braking force of the impacts. Or the frequency of the impacts may be regulated by means of a small motor for the same purpose.

Abstract: 1521950 Integrated circuit metallization INTERNATIONAL BUSINESS MACHINES CORP 22 June 1977 [3 July 1976] 26166/77 Heading H1K To facilitate planarization of subsequently applied metallization a layer of polymeric material is applied to a surface of a body bearing a pattern of metallization, partially cured, reduced in thickness to leave the metallization, only thinly covered (1,000- 2,000 ), further cured and then coated with quartz, e.g. by cathode sputtering. The metallization may be Al or Al-Cu-Si, the polymer a photoresist comprising an o-diazoarylquinone-cresol formaldehyde or soluble formaldehyde resin, containing a peroxide polymerization initiator or a radical forming agent such as azo-bis-isobutyronitril, and is applied by spin coating. Thinning is effected in a phosphoric acid-potassium permanganate solution. Via holes may be etched in the quartz, the exposed metallization cleaned in buffered HF and a second similar patterned metallization layer formed using a lift-off or etching process.

Title: Improvements in or relating to bathing caps
IPC: A42B1/12
Filed: 1948-10-08
Abstract: 652,910. Bathing caps. HANSEN, P., and FRANKLIN & SONS, Ltd., J. G. Oct. 8, 1948, No. 26315. [Class 63] A bathing cap 1 which may be made of loaded, synthetic or pure rubber is provided with a separate internal brim 2 made of the same material or of vulcanized nearly pure rubber. The inner brim material is thinner and more elastic than that used for the outer cap proper so that it can expand radially to form a seal without producing undue pressure around the head of a wearer. The ring-shaped inner brim, which may be folded back on itself, may be made by seaming together one or more pieces of sheet material, by clipping, or by moulding. The upper edge of this inner brim may be fixed to the inside of the cap proper by rubber solution or by vulcanizing. A strengthening ring of rubber may be attached to the upper edge of the inner brim and also to the inside of the cap proper. The inner brim may be the free depending edge of a complete inner cap fixed by the crown portion to the inside of the cap proper.

Abstract: 922,150. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 31, 1959 [Aug. 4, 1958], No. 26352/59. Class 37. A method of making strips of semi-conductor material of uniform length comprises dividing a rod into slices by cuts perpendicular to its longitudinal axis with a spacing at least as long as a strip, and parallel cuts parallel to the axis of the rod with a spacing corresponding to the strip thickness, and dividing the slices into strips along parallel lines. In an example a germanium or silicon rod 25 (Fig. 5) is cut along lines 27 and then along lines 29 (Fig. 6), or vice versa, and the resultant slices 28 divided into strips along lines 30 (Fig. 7) or along lines perpendicular to this. Transistors are formed from the resulting strips by alloying dots to corresponding points on opposite faces along the length of the strips and dividing the strip between each pair of dots.

Abstract: 964,528. Grinding crankshafts. O. WALD. RICH. July 20, 1961 [July 27, 1960], No. 26411/61. Heading B3D. A crankshaft grinding machine in which the crankshaft is held vertically comprises a rotary table 3 having an opening 4 and a clamping device on the table by which a journal 5 may be clamped at a distance from the axis of rotation 6 of the table corresponding to the throw 7, and a grinding device beside the table having a disc 9 journalled in a vertically movable spindle head 10 on a slide rest 11 which is radially adjustable in relation to the rotational axis of the table 3. The clamping device is also radially adjustable to accommodate crankshafts of different throw and to permit grinding of the journals. The vertical movement of the grinding head and the first part of the radial movement of the slide 11 may be effected hydraulically; a mechanical fine adjustment may be used for feed. After grinding the pins or journals above the table the shaft is inverted to grind those of the other half of the shaft. A holding device 14 engages the top end of the work and a crane 12, swing- able about an axis 15, lifts the work from or lowers it into the opening in the table 3. A wire-rope winch 13 is rotated by a shaft 18 in synchronism with the table 3 and the weight of the work is hydraulically counter-balanced by a piston 19 in a cylinder 18 coaxially aligned with the rotational axis 6 of the table. Alternatively a spring-operated counter-balance system may be used. Modifications of the lifting gear are illustrated in Figs. 2 and 3 (not shown), in which a telescopic member is fitted between the end support 14 and the crane frame 12 which is hydraulically operated to raise or lower the work and to counterbalance its weight. The offset corresponding to the crankshaft throw may be provided at the lower end of the telescopic member (Fig. 2) or at the upper end (Fig. 3).

IPC: C07C59/68
Filed: 1957-08-23
Abstract: In a process for the production of an alkali metal or alkaline earth metal salt of a g -aryloxybutyric acid which can be substituted in the aryl group a mixture of a phenol and an alkali metal hydroxide is rendered anhydrous to form the corresponding phenate and g -butyrolactone is introduced and heated with this, the process being carried out in a reaction vessel capable of being heated and in which a mixing or pulverizing action on the contents is obtained by movement under gravity within the vessel of balls or other bodies when the vessel is rotated about a suitable axis.  Suitable reactions mentioned include ball mills and rotary autoclaves containing balls or other bodies made of steel or other suitable heavy material. Preferably the reactor is vacuum tight and provision is made for reducing the pressure inside it.  The process is suitable for the production of salt of g -phenoxybutyric acids, e.g., of phenoxybutyric acid, g -(2 : 4 - dichlorophenoxy)-and g -(2-methyl-4-chlorophenoxy) butyric acids.  The free acids are obtained by acidification of aqueous solutions of the alkali metal salts of the acids.  Examples are furnished.
