Abstract: 332,993. Coe, H. S. May 28, 1929. Density separators; discharging.-A separator for treating liquids is supplied with an additional liquid to prevent clogging of the discharge ports, and to maintain a zone of fluid treating material adjacent the periphery of the rotary chamber. The shaft 11. Fig. 1, supported by the bearing 12 carries the separating chamber enclosed by two truncated conical sections 16, 17 which are connected by flanges 18. Conical liner plates 47 are arranged in the chamber. and a central tube 24 conveys the liquid to be treated to the bottom of the chamber. Discharge ports 28, 29, 30 are provided and the ports 28, 29 may be rendered adjustable by the lazy tongs 31 and sliding ring 32. The ports 30 are formed in pipes 34 provided also with discharge ports 36 at their inner ends. At the lower end of the chamber is a section 19 which acts as a pump to force liquid up through the space 38 between the plate 37 and the wall 17. The section 19 is provided with vanes 41, and the separating chamber may be formed with pockets leading to the discharge ports 30. The separator is placed in a tank 52, so that the lower end of the section 19 is immersed in fluid. The liquid to be treated is supplied through the central tube 24, and the separated constituents are discharged through the ports 28, 29 to the pipes 56, 57 and through the ports 30, 36 into the casing 52. The discharge of the heavy constituent through the ports 30, 36 is aided by the liquid, which may be discharged material, pumped up through the section 19 and passage 38. This prevents clogging at the ports and maintains a zone of treated material in the chamber so that no untreated material is discharged. The rate at which this liquid is supplied may be varied to compensate for wear on the discharge ports 30 ; the variation is obtained by regulation of the ports 43 which can be adjusted in position by screwing. The level of the flexible discharge outlet 58 from the casing 52 is adjustable. In a modification where the ports 28 are not used, clean liquid is discharged through the ports 29 and colloidal matter is discharged through the ports 30, 36. Water is supplied to a vessel surrounding the section 19 to be pumped through the space 38. The colloidal matter passes into the casing from which it is removed by a conveyer.
Patent GB-793802-A (GB)
Title: Improvements in or relating to the preparation of aromatic isothiocyanates
Filed: 1955-06-08
Abstract: Aromatic isothiocyanates are prepared by reacting the ammonium salt of an N-aryl dithiocarbamic acid with an ammonium or alkali metal or alkaline earth metal salt of an a -halogenated carboxylic acid, the salt obtained which is derived from an acid having the formula <FORM:0793802/IV (b)/1> in which R is an aromatic group and R1 is an alkylene or aralkylene group, being reacted in an aqueous medium at a pH above approximately 5 with a salt of a metal having a standard reduction potential higher than aluminium.  The ammonium N-aryl-dithiocarbamates may be prepared by reacting a primary aromatic amine with carbon disulphide and ammonia.  Aliphatic and araliphatic a -halogenated carboxylic acid salts may be used, sodium monochloroacetate being preferred.  When the salt of an acid of the above formula is treated with the salt of a metal such as zinc, iron, manganese or lead, at a pH below 5 the metal salt of the acid is obtained and may subsequently by treatment at a pH greater than 5, be converted into the isothiocyanate.  A further alternative is to react the ammonium N-aryl-dithiocarbamate in aqueous medium at a pH above 5 with the salt of an a -halogenated carboxylic acid and a metal having a standard reduction potential higher than aluminium.  In examples: (1) aniline, carbon disulphide and ammonia are reacted to give ammonium phenyldithiocarbamate which is reacted with sodium monochloracetate, the resultant salt being reacted with zinc chloride with concurrent addition of sodium hydroxide to give a pH of 7 and phenyl isothiocyanate and the monosodium salt of the zinc mercaptide of thiolacetic acid are obtained; (2) as in (1) but using ferrous sulphate, phenylisothiocyanate and the corresponding iron mercaptide are obtained; (3) as in (1) but using sodium monochloropropionate; (4) as in (1) but using p-phenylene diamine, ammonium p-phenylene-bis-dithiocarbamate is obtained, reacted with sodium monochloracetate, the resultant salt being reacted either (a) with zinc chloride to give the zinc salt of p-phenylenebis - (s - carboxymethyl) - dithiocarbamic acid which may be converted at a pH of 7 into p-phenylene diisothiocyanate, or (b) with zinc chloride together with sodium hydroxide to maintain a pH of 7 and give the diisothiocyanate directly; (5) as in (1) but using N-monoacetyl - p - phenylenediamine, p - phenetidine, p-bromo- or -chloro-aniline or a -naphthylamine as starting materials, p-acetylamino- or -ethoxy- or -bromo- or -chloro-phenyl isothiocyanate and a -naphthylisothiocyanate are obtained.

Patent GB-388629-A (GB)
Title: Improvements in or relating to gramophones
IPC: G11B19/265
Filed: 1932-06-13
Abstract: 388,629. Gramophones. GELL, J., 123, Upper Tollington Park, London. June 13, 1932, No. 16681. [Class 40 (ii).] A constant linear speed drive mechanism for gramophones comprises a friction wheel mounted on a splined shaft with which is associated a rocking arm carrying half-nuts so that when the rocking arm is rocked in one direction the half-nuts engage with two threaded shafts parallel to the splined shaft but when rocked in the other direction the half-nuts are disengaged therefrom. A shaft 1, Fig. 1, connected with the driving motor, is geared to a gear wheel 3 fixed to a splined horizontal shaft 6 which carries a friction wheel 9 rotatable therewith but free to slide thereon. A rocking arm 11, Figs. 1 and 8, pivoted on the splined shaft 6 is formed of two side pieces 11a, 11b between which are the friction wheel 9 and two half-nuts 12, 13 which can engage with threaded shafts 14, 15. When, during operation of the machine, the half-nuts are in engagement with the shafts, the friction wheel 9 is rotated and traversed radially of the turntable to produce constant linear speed of the record under the stylus. The arm 11 can be rocked about the shaft 6 by means of a shaft 20 pivoted eccentrically in bearings 21, 22 and engaging with a roller 11c on the rocking arm. When the shaft 20 is turned in one direction, the half-nuts of the rocking arm engage with the threaded shafts 14, 15, but when turned in the opposite direction the half-nuts are freed from the threaded shafts. A shaft 24 carries an eccentric cam 28, Fig. 4, so that when it is given a half turn, an arm 29 pivoted on the shaft 20 and carrying a wheel 30 is moved to raise the turntable 31 and its associated mechanism so that the rocking arm can be moved to any desired position. Secured to the rocking arm are rods 32, 33 connected together by a U-piece 37 so that the rocking arm with the friction wheel may be moved manually when the half-nuts 12, 13 have been disengaged from the shafts 14, 15. A member 55 is adapted to break the circuit of the driving motor when the friction wheel has been moved almost to the end of its radial travel. The turntable 31 is fixed to a cup 45, Fig. 6, mounted on a hollow shaft 42 rotatable on ball bearings about a spindle 38. The spindle 38 is screwed to a cup 40 fixed to the base-plate of the machine. To enable the hollow shaft 42 to rise and fall when the turntable 31 is lifted by actuation of the shaft 24, the ball bearings 43, 44 are a sliding fit on the spindle 38. To the shaft 42 is fixed a worm gear 48 which drives gears 49, 50, Fig. 1, on the threaded shafts 14, 15, respectively. An additional train of gears may be inserted between the shafts 14, 15. When used for recording sound an L-shaped arm 61, Fig. 7, is attached to the tone-arm by a flexible connection 62 and is secured also to the U-shaped piece 37 to move in sympathy with the friction wheel 9.

Title: Improvements relating to automatic gauging machines
IPC: B07C5/06
Filed: 1943-10-13
Abstract: 571,834. Sorting by gauging. SOUTHALL & SMITH, Ltd., and GWILT, C. Oct. 13, 1943, No. 16767. [Class 106 (ii)] A machine for automatically gauging small articles, such as detonator caps e, comprises the combination with a support b for a plurality of gauges c<1>, c<2>, c<3>, c<4>, of two sets of push rods m, n arranged on opposite sides of the gauges and adapted to push into or out of the gauges the articles to be gauged, means for reciprocating the push rods, the said means including springs w or weights for advancing the rods n which push the articles towards the gauges, and a reciprocating carrier o adapted to move the articles e individually from the loading position to each of the gauges in turn. The articles e are fed one at a time from a shoot h by a push-rod m attached to a bar p reciprocated under the control of a cam r and a spring-pressed lever q. A projection 27 of the bar p has a cam surface controlling a lever 24 carrying a stop 23 which releases the articles one at a time and retains the remainder in the shoot while the bottom-most is projected into a lateral guide-way g. A carrier o with. four recesses 3 is controlled by a cam 14 and a spring-pressed lever 13 and also by a cam 8, Fig. 1, roller 9 and spring-pressed slide 6, whereby the carrier moves first to the left in Fig. 3 to embrace the detonator cap 3 and then moves laterally to move the cap e to the first gauge c<1>, releases the cap and then returns to original position. Simultaneously, the carrier moves caps in front of gauges c<1>, c<2>, c<3> to the next station. Under the influence of springs w or weights acting on cords u, bars t drive pushrods n to project the caps e against the gauges c<1>, c<2>, c<3> to gauge minimum diameter, minimum height and maximum height respectively. The push-rods n and bars t are retracted by a bar 12 under the control of a lever y and a cam z..If a cap passes through either of gauges c<1> or c<2> it falls through an aperture to be discarded. If it fails to pass through the gauges c<1>, c<2>, c<3> it is returned to the guide-way g by a push-rod m individual to the gauge, and in the last case is passed to a rejection guide-way (not shown) by the carrier o. If a cap passes through the gauge c<3> it is presented to a gauge c' in line with c<3> to measure maximum diameter. If it fails to pass it is ejected through a trap-door 16, opened at the appropriate part of the cycle under the control of a cam 21 spring-pressed lever 17 and link 18. If it passes through gauge c<4> the cap is satisfactory.
