Abstract: 649,526. Uniting by fusion; soldering and brazing. ROSS & PARTNERS, Ltd., D., and ROSS, D. June 27, 1947, No. 17052. [Class 83 (iv)] In soldering, brazing or welding wires, rods or strips, particularly fine wires, the wires are clamped between two pairs of carbon or like bad conducting electrodes, electric current being passed through the pairs of electrodes. On a box a, housing a transformer, is fixed a metal base f provided with channels in which two carbon electrodes g<SP>1</SP>, g<SP>2</SP> are fixed by screws h, the base being connected by a lead e to one terminal of the transformer. Co-operating with the electrodes g<SP>1</SP>, g<SP>2</SP> are a pair of electrodes l<SP>1</SP>, l<SP>2</SP> fixed in arms k<SP>1</SP>, k<SP>2</SP>, which are pivoted on a bracket i insulated from the base, the bracket being connected by lead d to the other transformer terminal.

Abstract: 1340401 Chord indicators; transposing music BADEV SA 26 May 1971 [5 Oct 1970] 17141/71 Heading G5X An indicator 3 of harmonics and of musical transpositions comprises two discs 1<SP>1</SP>, 2<SP>1</SP> secured at their centres 3<SP>1</SP> for relative rotation. The small disc 2<SP>1</SP> has its periphery divided into numbered sectors (1-12) and the outer disc 1 has its periphery divided into corresponding sectors, each sector containing a representation of a note from the harmonic scale; the major chord, the relative minor chord and the seventh chord or said note written on music staves, the stave showing the position and number of sharps and flats relative to C without any sharps or flats; and a representation of a way of fingering these chords for a guitar. The order arrangement of the harmonic notes is such that when sectors 10, 11, 12 give the interval with respect to an instrumentation C of instruments in E flat, B flat and F flat and the sectors 12, 2, 4, 5 fall opposite the dominated 7th, the sub Dominant major, the related minor and the Sub Dominant minor of any one of the harmonic notes (keynotes) to which the arrow F is set. Musical transpositions are effected, knowing the keynote and its transpose, by noting the number on disc 2 adjacent the transpose when the arrow is set to the keynote. The transpose of each note on the disc 1 is obtained by plating the arrow opposite its sector and reading off the note oppo - site the previously noted number. Certain typical chord series, e.g. Anatoles, Blues chords &c. may be obtained by using instructions which may be printed in the centre of disc 2. The disc 1 may be replaced by a rectangular support having the data printed thereon and another indicator disc may be used on the reverse side of this disc or support.

Abstract: 920,990. Soil stabilization. K. SZEPESI. May 11, 1961, No. 17189/61. Class 68 (1). Excavations are waterproofed by flooding the excavation with an aqueous calcium hydroxide lye which permeates the soil around the excavation to form a water-impermeable, gelatinous layer of hydrated silica-alumina clay containing calcium ions. Alternately said layer may be formed by skimming soil from the sides and bottom of an excavation spreading quicklime on the now exposed surfaces of the excavation, replacing the skimmed off soil over the quicklime and then flooding the excavation with water.

Title: Improvements in and relating to cathodes for ionization detection devices
IPC: H01J47/08
Filed: 1950-07-10
Abstract: 677,856. Discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. July 10, 1950 [July 22, 1949], No. 17213/50. Class 39 (i). A method of producing a cathode for an ionization detection device comprises applying a metal halide to the inner surface of an envelope of vitreous or ceramic material which is heated so as to form thereon an electrically conductive coating. As shown, the tube 1, of glass or ceramic material, is flared outwardly at 2 to receive a thin mica sheet or window 3 which is sealed to the tube 1 by means of a low melting-point glass 4. The end of the tube opposite the window 3 is sealed and a wire anode 5 of chromium-iron alloy, tungsten, or other suitable metal, is mounted within the tube and passes through the tube wall, a glass bead 6 being fused to the inner end of the anode to prevent leakage of the discharge from the sharp point. An electrically conductive coating produced by treatment with tin chloride covers the inner surface of the tube 1, electrical contact being provided by a split ring or band 8 of metal connected to a wire 9 and fitting tightly on the coating 7, the metal parts being polished and oxidized to prevent corrosion or absorption of the halogen gas. The atmosphere of the tube consists of a halogen and other inert gas or gases, a typical composition being 1 part by volume of halogen to 760 parts by volume of neon and 4 parts by volume of argon. The non - corroding and non - halogen absorbing cathode is produced by treating the inner surface of the envelope with a metal halide which should preferably have a boiling point below the temperature at which the coating is formed, tin chloride being preferred, but other halides such as those of iron, titanium, columbium, aluminium, and tantalum may be used. Preferably the tin chloride is dissolved in a solution of alcohol and sprayed into the envelope, which is maintained at a temperature of 400‹ to 700‹ C., a preferred solution consisting of 50 parts by weight of tin chloride dissolved in 45 parts by weight of ethyl alcohol. In a modification, Fig. 2 (not shown), the tube has no mica window, the radiation to be measured passing directly through the thin side walls, which are coated on their inner surface with a conductive film as described.

[Class 8 (ii)] [Also in Group XXIX] In a fluid-pressure servomotor control system in which a conduit or conduits 3 lead pressure fluid to and from the cylinder 2 of the servomotor, the pressure fluid is passed into each conduit 3 with a sudden change of direction on entering the latter and is discharged from the conduit in a smooth path and w'thout change of direction, so that the discharge fluid will not interfere with the relay 1, no movable control member being employed. As shown, Fig. 1, each conduit may be provided with an inflow channel 5, of uniform cross-section and angularly disposed to the axis thereof, and a discharge channel 4, the sectional area of which may increase towards its opening 7. The cross-section of the conduit may be constricted adjacent its junction with the channels 4, 5, alternatively the channel 4 may be enlarged at a point adjacent the channel 5. Fig. 4 shows a conduit of arcuate form, with the inflow channel 5 on the inside of the curve whereby the return fluid flows under centrifugal force along the outer wall of the conduit and passes to the discharge channel 4 in a direction away from the inflow channel. Specification 224,655, [Class 8 (ii)], J, is referred to.

Abstract: 210,699. Original Patents Co., and Devlin, C. July 5, 1923. Packeting pills &c. in receptacles.- Relates to apparatus for filling glass tubes, boxes, &c. with pills or the like, and inserting a cork. The pills are contained in a hopper 1, Fig. 1, at the base of which a rotatable disc 6 is mounted on a spindle 16 and is normally held by a spring in a casing 15 so that apertures 7 are in the inoperative position beneath a flanged plate 8. The disc is partially rotated, from a treadle &c. attached to a hook 24, by a cord 19 attached to an arm 18, and returns beneath the plate 8 with a predetermined number of pills in the apertures 7, which fall into a trough 10 and collect in a tubular extension 11, Figs. 1 and 6. A sleeve 13, apertured at 14, slides in a guide 12 on the extension and normally arrests the pills. A glass tube &c. is placed on a sliding table 26 and in an aperture 25 at the base of the guide 12, thereby raising the sleeve so that the aperture 14 registers with the extension 11, and allows the pills to fall into the glass tube. A cork is placed in a collar 30 on a plate 31, and, on the descent of a sliding framework 21 carrying a plunger 28, a lever 41 turns anticlockwise under the action of a spring 42 and draws the plate 31 to the right so that the cork is in the path of the plunger, the continued descent of which forces the cork into the tube. At the same time a slide 36 is moved to the left by a link 37 on the arm 18, and a hook 34 engages an abutment 35 on the plate 26 supporting the bottle. On the return stroke, the plate 26 is drawn to the right and the bottle &c. falls out of the machine, a bar 39 causing the hook 34 to disengage the plate 26, which returns to the left under the action of a spring 27. The top of the frame 21 carrying the plunger 28 on its return stroke forces the lever 41 and the plate 31 into the original position. A shield may be disposed in front of the frame 21 to protect the operator.
