Title: Improvements in the method of and apparatus for making emulsions
IPC: B01F3/08
Filed: 1921-08-22
Abstract: 185,618. Hutchings, G. B. Aug. 22, 1921. Mixing-apparatus.-A centri fugal apparatus for making emulsions is formed in the shape of a truncated cone 19 with a recess 25 in its base and a downwardly-extending flange 23. Ducts 26 run through the cone as shown, and branch ducts 27 run from the ducts 26 to the. recess 25. The materials to be emulsified are drawn up into the branch ducts 27 as the apparatus rotates and pass down the main ducts 26. The working may take place if desired in a partial vacuum, and the fineness of the emulsion can be controlled by varying the diameter of the ducts. In a modification the branch ducts enter the main ducts approximately at right-angles.

Title: Improvements in ticket issuing machines
IPC: G07B5/02
Filed: 1925-09-07
Abstract: 257,740. March, E. Sept. 7, 1925. Tickets, issuing.- Either of two ticketissuing machines can be rendered operative by sliding a common driving-shaft to engage with one and disengage from the other, the axial movement of the shaft being possible only when this shaft is in home position. Simultaneously with the sliding of the shaft, a detent is shifted to free and lock the respective machines. The two machines a, b have each a hollow operating shaft d notched at e to be engaged by a transverse pin f in a crank-handle shaft c when this is correspondingly positioned. The machine not in use is locked by a detent h held by a spring-plunger i and rocked by the passage of the pin f from one machine to the other. A cone j on the shaft c controls the position of an indicating lever to display the character of the machine in operative condition. According to the Provisional Specification a gate may be arranged to prevent the shaft c from sliding except when in home position, and the detent may have the form of a ratchet and pawl normally preventing drive of the associated machine until a eam on shaft c when slid raises the pawl.

Abstract: 346,634. Liquid-fuel burners. LANSER, A., Corseaux, Vevey, Switzerland. July 29, 1930, No. 22853. Convention date, July 29, 1929. [Class 75 (i).] The fuel-supplying means for a heavy oil burner are grouped in a single box-like casing c having neither joint nor union in its lower part, this casing being easily removable for cleaning or repair of parts and being replaceable by a similar casing containing similar fuel-supplying means. The casing in the arrangement shown forms a tank into which the fuel is delivered by a suction pump a from a supply conduit b and from which the fuel is forced by a pressure pump d to a conduit f leading to the burner g. The pumps a, d are driven by the same shaft, a double valve h actuated by a float i determining whether fuel is drawn by the pump a from the conduit b or the casing. A valve k in the suction pipe b of the pump a is opened against the resistance of a spring by the pressure of the fuel delivered by the pump d on a piston k<2>. The delivery pressure of the pump d is regulated by an escape valve j. Filters m, n are arranged in the casing in the suction and delivery pipes b, f and a strainer o is provided in the return pipe for unburnt fuel dripping from the burner. The casing c is fitted with a cover c<1>. In order to substitute a new casing it is only necessary to break unions in the conduits b, f and the unburnt fuel return pipe and to disengage the pump driving- shaft.

Abstract: An antibiotic josamycin, active against gram-positive bacteria, is a base forming salts with acids, e.g. hydrochloric and tartaric acid; the base forms colourless needle crystals of melting point 130-133 DEG  C.; it has a molecular weight of 865 and formula C40H68NO14; the elementary analysis is C = 60.63%, H = 8.49%, N = 1.77% and O = 28.75%; it is soluble in acidic water, methanol, ethanol, chloroform, ethyl acetate and acetone, less so in benzene, ether and CCl4, and slightly soluble in water, petroleum ether, ligroin and n-hexane; it has a pK1a of 7.1 when titrated in aqueous methanol; <PICT:1107112/C2/1> <PICT:1107112/C2/2> a specific rotation <FORM:1107112/C2/1> of - 70 degrees (C = 1% in ethanol); ultraviolet absorption max. at 232 mm  <FORM:1107112/C2/2> in methanol as in Fig. 1; I.R. absorption as in Fig. 2; Rf of 0.49 in paper chromatography using benzene-chloroform (1: 1). Josamycin is prepared by cultivating a strain of Streptomyces narbonensis var. josamyceticus in an aqueous medium of a conventional type under aerobic conditions.  It is recovered from (a) the whole or clarified broth by extraction with a water-immiscible solvent at neutral or alkaline pH, (b) the separated mycelium by extraction with aqueous acid. The extraction into organic solvent and aqueous acid is repeated.  Further purification is by adsorption on alumina, followed by precipitation from benzene solution by the addition of a non-solvent such as n-hexane. Alternatively, the antibiotic may be adsorbed on activated carbon or a weakly acidic cation-exchanger, e.g. "Amberlite" (Trade Mark) IRC 50, eluted therefrom with acidic water or aqueous water-miscible solvent or neutral or acidic alcohol, and further purified by solvent extraction and crystallization from solvents.

Title: Improvements in electric time limit relays of the induction type

Filed: 1924-10-01
Abstract: 236,424. Petersen, W. H., and Allmanna Svenska Elektriska Aktiebolaget. Oct. 1, 1924. Induction relays.-An induction disc 1 or the like is acted upon by electromagnetic forces which have a component tangential to the disc tending to rotate the disc and a component at right angles to the tangential component tending to displace the disc bodily. According to the construction shown in Fig. 1, the disc 1 is mounted in a frame 4 which is pivoted at 5 and moves between stops 6, and a sector 10 pivoted to the frame at 11 engages a pinion 9 on the disc. The disc is acted upon by an electromagnet 3 the poles of which are embraced by a short-circuited winding 8 arranged obliquely so that the driving force of the magnet acts in a direction making an angie with the tangent. The disc 1 normally only partly covers the poles of the magnet 3 and the tangential component of the force exerted by the latter is then insufficient to rotate the disc and lift the heavy sector 10. Upon excess current, however, the radial component of the force lifts the disc 1 so that the poles of the magnet 3 are fully covered, and the disc 1 then rotates, and the sector moves upwards and after a time interval, actuates contacts. In a modification, Fig. 2, the magnet 3 has two pairs of poles arranged in parallel, one pair shaded at 15 so as to exert a tangential force on the disc and the other pair shaded at 17 to exert a radial force. Holes 18 are also arranged in the disc so that the second pair of poles do not exert their maximum force till the disc 1 has been raised. In another modification, Fig. 4, the magnet 3 has a second pair of poles 20 arranged to act vertically on a member 19 fixed to the frame 4. A braking magnet 21 is also provided. Specification 178,319 is referred to.

Abstract: 1,272,334. Controlling burners. SIMICON CO. 14 May, 1970 [15 Oct., 1969], No. 23439/70. Heading F4T. A combustion control device for a furnace comprises a burner 34 control means connected to the A.C. mains, e.g. a source of 120 V., a low voltage (8 V.) control circuit including a cadmium sulphide flame detector 32, a semiconductor device in the form of silicon controlled rectifier SCR1, to actuate the control means in response to a signal from the flame detector 32, a bimetallic lockout safety switch 20 (see Specification 1,272,335) for interrupting current flow through the rectifier SCR1, a triac Q1 and a thermostat 24, a reed switch 25 having normally open contacts actuating the burner control means and being controlled by a pair of electrically insulated coils RC1, RC2 having additive flux linkages whereby energization of both coils RC1, RC2 is necessary to effect closing of switch 20 and continued energization of one coil RC1, by current rectified by diode D1 and capacitor C2, maintains switch closure. When thermostat 24 senses a demand for heat, flux is established in coil RC1 and the gate 60 of silica controlled rectifier SCR1 is triggered, and if the flame detector 32 senses no flame, current is riot shunted from gate 60, and silicon controlled rectifier SCR1 conducts, coil RC2 is energized to close contacts 26, 28 of reed switch 25, and triac Q1 passes power to burner 34. If detector 32 continues to sense no flame current in heater coil 23 effects cut-out of switch 20 after about 15 sec., but if flame is sensed, current will be shunted from gate 60 and cut-out will not occur. The device will fail-safe upon circuit failure.
