Abstract: 1,268,477. Chamfering tablets. SHIONOGI & CO. Ltd. 30 June, 1970 [30 June, 1969; 28 Aug., 1969; 11 May, 1970], No. 31748/70. Heading A5B. [Also in Divisions B3 and B5] An apparatus for chamfering circular tablets comprises at least one member 1 having a grinding or abrading surface, and at least one guiding member 2 arranged against the surface along a line which intersects the direction of movement at an angle other than a right angle, the grinding member having an inlet 27 and outlet 28 for the tablets and groove sections 21, 23 facing the grinding or abrading surface and arranged to present the circular edges of the tablets to the surface. The tablets may be formed in a tableting press and have a circular shape with convex faces and, after chamfering, have an ellipsoid or spherical shape. The grinding or abrading surface may be formed as a file of stainless or tool steel chromium plated or be any roughened surface. The surface may be formed on a disc 1, and the guiding member 2 consists of a curved member having a tubular section 22 joining the guide sections 21, 23. Tablets are fed into the inlet 27 of the guiding member and are carried along the member by contact with the disc, the tablets being chamfered along one edge while in the section 21, and tilted while in the tubular section 22 so that their other edges are chamfered while in the section 23. The inclination of the tablets while in the sections 21, 23 may be varied so that the tablets have rounded chamfers. In another embodiment, the grinding or abrading surface is provided by two annular discs, the guiding member being straight; the two discs may be in the same or parallel planes and rotate about parallel axes in the same direction. Alternatively, the discs may be arranged to rotate about the same axis and be arranged one within the other, the guiding member being curved. In a similar embodiment, the grinding surfaces face one another so that the tablets do not have to be tilted in the opposite direction as they pass along the tubular section from one surface to the other. In other arrangements the grinding surfaces are formed on the curved surfaces of cylindrical, conical or hyperbolic drums, or on endless bands.

Abstract: 644,083. Automatic voltage control systems. MARCONI INSTRUMENTS, Ltd. Dec. 2, 1947, No. 31848. [Class 38 (iv)] [Also in Group XL (c)] An oscillator comprises an amplifier to which both positive and negative feed-back are applied by means of a resistance-capacity bridge network in which one arm is a valve acting as a variable impedance, being controlled by a control potential derived from the output of the amplifier. A double triode V1 is coupled by a common cathode resistance 5 and the second element is coupled to a further stage V2, feeding a " Weir " type bridge network. Positive feed-back is applied to the grid of the second element of VI from one arm of the bridge, comprising the anode-cathode path of a valve V3, while negative feed-back is applied to the first element of V1 from the opposite corner of the bridge. The impedance of the valve V3 is reduced by negative feed-back over resistances 40, 41 and is controlled by the grid bias, which is derived from the amplifier output by means of a diode rectifier 23 ; a delay bias is applied to the diode from a negative source over resistance 28 and a gas-discharge tube 26. The sensitivity of control may be increased by further amplification, such as a D.C. amplifier inserted between the diode 23 and valve V3.

Abstract: 825,571. Screw-driving machines and attachments. RUSSELL AUTO-FEED SCREWDRIVERS Ltd. Oct. 17, 1957 [Oct. 20, 1956], No. 32001/56. Class 83 (3). In a screw-driving machine in which screws from a hopper 10 are fed, through a guide (not shown), to a nozzle receiving the rotatable and axially-movable screw-driving spindle, means for controlling the delivery of screws to the nozzle comprises a gating device (not shown), and a passage 22 of adjustable cross-section to fit the heads 23 of the screws, the screwshanks 20 depending through a guide-slot 19 in the lower wall of the passage. The spindle may be driven, through a torque-limiting clutch, from a shaft connected to the spindle of a drilling-machine. The shaft rotates an eccentric bush-bearing in the hopper, which it oscillates to feed the screws outwardly along an arcuate slot leading into the passage 22, rotation of the hopper being prevented by contact between an arm on the hopper and the post of the drilling-machine. Adjustment of the cross-section of the passage 22 may be effected by interchangeable slip-plates 21 forming the top of the passage, the lower-wall being formed by a slotted plate 13 secured to the floor of the hopper by screws engaging tappedopenings 17, 18. The slip-plates 21 of different thicknesses or cross-sectional profile, or both, e.g. to suit round-head screws, may fit a dovetail-slot in the floor 11 of the hopper. The plates 21 may be wider at the upper end to increase the grip, and have a ground lower slipface. Instead of interchangeable slip-plates, the lower-plate 13 may be interchangeable with others of different thickness, or either plate may be adjustable towards the other, e.g. the slip plate may be adjusted by screws. Alternatively, the slip-plate may be replaced by a stack of strips clamped together with their edges extending along the passage and adjustable to vary the cross-section of the passage. The gating device comprises an escapement having arresting and parting fingers oscillating beneath the slip-plate to feed screws in timedrelation with the' operations of the screwdriver. The screws pass from the passage 22 into a two-part delivery tube leading into the nozzle, above the end of the nozzle which bears on the work. A universal joint is provided between the upper part of the tube and the oscillating hopper.

Title: Stabilization of dialkyl haloacetals
Filed: 1948-12-14
Abstract: Dialkyl haloacetals such as Cl.CH2.CH(OCH3)2 are stabilized against formation of acid and peroxides by mixing therewith a small proportion of triethanolamine.  The latter may be present in amounts up to 0.1 per cent by weight at temperatures around 20 DEG  C. Larger amounts (e.g. 1 to 2 per cent) may be used if the solubility is increased by increase of temperature or addition of small amounts of water.  An example is given.  Poor results are stated to be obtained if the triethanolamine is replaced by other amines such as mono- and di-ethanolamines, triethylamine, octylamine, cyclohexylamine and phenyl-a - and b -naphthylamines. p

Patent GB-412244-A (GB)
Title: Process for the surface coating of iron and steel
IPC: C23F1/28
Filed: 1932-11-16
Abstract: A process for surface coating iron or steel consists in first cleaning or pickling, for example with sulphuric or hydrochloric acid, treating with a reagent which during the treatment contains a ferrous salt, an acid, and an oxidizing agent, such a reagent being nitric acid, so that a ferric salt is produced in situ, said treatment being continued until the planar structure of the metal grains is exhibited, cleaning the surface, and finally coating with vitreous enamel or other paint-like coating.  The pickled sheets may, for example, be submerged for 40 secs. in 8 per cent nitric acid, scrubbed, neutralized with hot 2 per cent trisodium phosphate, and dried by hot air.  The temperature and concentration of the acid, and time of immersion may be varied. Solutions containing ferrous salts together with ferric salts, chlorates, nitrates, nitric acid, chromates, or oxygen, which is bubbled therethrough, may be employed. A sufficient concentration of oxidizing agent and of an acid should be present to maintain a concentration of ferric salt of 5 per cent or more.  A solution containing 2-3 per cent or less of sodium chlorate and 4 per cent of sulphuric acid is efficient at about 160 DEG  F.  Other reagent baths contain about 20 per cent of ferric chloride, or 2 per cent or 5 per cent of nitric acid.  The black scum left by the etching may be removed by treatment with a dilute solution of sodium nitrate, e.g. 2-4 per cent, and sulphuric acid, e.g. 4-5 per cent, or of nitric acid, prior to the scrubbing.  The surface is thus rendered passive to oxidation.  The treated surface can be white enamelled using two coatings only and scaling is eliminated.  Reference has been directed by the Comptroller to Specifications 16451/88, [Class 82], 25393/13, 236,241, [both in Class 82 (ii)], and 375,599.

Abstract: 966,941. Pulse shaping circuits. MUIRHEAD & CO. Ltd. May 13, 1963 [Aug. 24, 1962) No. 32665/62. Heading H3P. A circuit for steepening the back edge of pulses comprises a capacitor 8 charged via a diode 6 and an attenuator 3 and discharged via a reverse diode 9 connected between the capacitor and the higher voltage side of the attenuator 3. When a positive pulse is applied to input terminal 1, capacitor 8 is charged via diode 6 to a voltage dependent on the setting of attenuator 3 and is discharged by diode 9 when the trailing edge of the input pulse reaches a voltage less than that to which capacitor 8 is charged. The fall time of the trailing edge is thus reduced. The pulse across capacitor 8 is amplified by a pentode 19 and D.C. restored to a voltage x by capacitor 20 and diode 22 before being fed to the grid of a cathode follower 24. The amplified pulse from the anode of pentode 19 is differentiated at 25 and the resulting positive pulses removed by diode 29. The negative differentiated pulses are amplified by pentode 27, D.C. restored by capacitor 30 and diode 32 to voltage y before being fed to the grid of cathode follower 33. Cathode followers 24, 33 have a common load 34 and are arranged so that only the valve with the more positive grid is conductive. The resulting output pulse thus has its leading edge formed by the amplified differentiated pulse whilst the flat top and trailing edge are provided by the output of pentode 19. The bottom of the output waveform is limited by diode 36. In Fig. 2 (not shown) diodes 6, 9 are driven by cathode followers.
