Abstract: 721,803. Setting up boxes. MACHINERY MANUFACTURING CO., Inc. Jan. 5, 1953. No. 322/53. Class 94 (1). [Also in Group II] A machine for setting up collapsed boxes comprises stationary and pivoting plates between which the box is squared, and side and end tuckers for folding in the bottom closing flaps, one side tucker being movable transversely to its tucking direction to clear an incoming collapsed box. The boxes are each fed from the base of a stack 17 by a reciprocating pusher 27 (see Group II), to rest between the stationary plate 108 and a plate 40 hinged at 107. The plate 40 swings through 90 degrees and the box is squared between the plates and brackets 109, 110. Tuckers 68, 69 are advanced to fold in flaps 7, 8 and the end tucker 74 pivots upwardly to force the flap 9 against yielding presser feet 118, 119. The feet 118, 119 position the flaps 9 on the tucker 74 and are then removed by the withdrawal of the tuckers 68, 69, by which they are carried, prior to the final tucking of the flap 9. The tucker 69, in addition to having horizontal motion, is reciprocated vertically by a cam 80 operating a slide 85 on a rod 75, the slide having pivoting connection with the tucker 69. The cam 80 also operates the plate 40 through a link 88. A set up box is ejected by the incoming collapsed box to fall down a shoot 134. All elements are adjustable as necessary to handle various sizes of box.

Patent GB-689379-A (GB)
Title: Improvements in or relating to telephone signalling arrangements employing alternatin currents
IPC: H04Q1/446
Filed: 1952-01-04
Abstract: 689,379. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Jan. 4, 1952 [March 3, 1951], No. 345/52. Class 40 (iv). In an arrangement for transmitting subscriber's dialling signals to an exchange, the subscriber's line circuit comprises an oscillator whose feed-back path includes the line between the exchange and the substation, the subscriber's dial contacts causing variations in impedance in the feed-back path. As shown, Fig. 2, the subscriber's line is connected via the transformer T1 in series with the feedback path of the oscillator V1a and when the switch hook contacts at the substation are normal the series circuit L7, C8 which is resonant at the oscillator frequency (2 Kc) is connected into the feed-back path so that V1a oscillates. When the hand-set is lifted the resonant circuit is disconnected and V1a ceases to oscillate. Each closure of the dial contacts connects up the resonant circuit L7, C7 to cause the oscillator to oscillate. The oscillator output is rectified at W1 and passed to the grid of valve V1b to operate the anode relay A which repeats the seizing and dialling signals to the automatic equipment. Rectifier W2 and resistance R4 are connected in series with a further winding of relay A to provide a measure of impulse correction. In a second embodiment, Fig. 3 (not shown), the subscriber's line is connected in shunt across the resonant portion of the oscillator feed-back path.. When the handset is lifted a low impedance resonant circuit is connected across the line to disable the oscillator, the dial contacts disconnecting this circuit to reenable the oscillator. In this arrangement the receive anode relay is provided with a slave operating release and dialling relays whose contacts are used to improve the impulsing loop to the exchange. The dialling relay is also provided with a winding energized by the exchange ringing current which is repeated thereby to line. In a third embodiment, Fig. 4, the dial contacts control the switching-in of a harmonic generator 10. The oscillator 1 feeds 2 Kc. current via the low-pass filter 3 to line. At the substation this current passes through the lowpass filter 8 and dial contacts x, y to the harmonic generator 10 which produces a 6 Kc. current which passes back via high-pass filters 9, 7 and a phase compensator 6 to the oscillator whose oscillations are thereby maintained. Since with this type of feed-back the oscillator is not self-starting a contact z and a resonant circuit LC are provided at the substation for emitting a transient 2 Kc. current. In a fourth embodiment, Fig. 5 (not shown), control of the feed-back circuit is effected over the earth phantom of the subscriber's line. The system is stated to be useful for signalling over power lines and also for mine telephone systems where the sparking inherent in D.C. systems must be avoided.

Title: A method and device for the burning of oil
IPC: F23D11/24
Filed: 1934-01-04
Abstract: 418,552. Liquid - fuel burners. MAINZER, C. E., and MAINZER, C., (trading as DE INDUSTRIEELE VOOR WARMTE TECHNIEK VOORHEEN BENNIT & CREMER), 145, Rijswijkscheweg, The Hague. Jan. 4, 1934, No. 375. Convention date, Jan. 9, 1933. [Class 75 (i).] In an oil-burning device the oil unmixed with air is delivered intermittently under high pressure in an atomized condition directly into the combustion space. In the apparatus shown, the oil is pumped through a passage 17 in the atomizer block to an annular groove 18 in a nozzle 13, the groove 18 being connected by three passages 19 to a chamber 16 communicating with a discharge orifice 14. The pressure of a spring 21 on a needle valve 11 controlling the orifice 14 is adjusted so that the oil prossure is just sufficient to lift the valve 11, the valve closing immediately after a small quantity of oil has passed. An intermittent discharge of atomized oil into the combustion chamber therefore takes place. A feeler 23 enables the operator to test whether the valve 11 is vibrating. The atomizer block is mounted in a hemispherical head 4 formed with air admission openings 5. Ignition of the oil is effected by the flame from a gas connection 7, combustion being stated to occur at about 50 cm. in front of the nozzle. A valve 10 enables air from the oil passages and oil leaking past the valve 11 to be discharged.

Filed: 1974-01-04
Abstract: 1440402 Methacrolein NIPPON ZEON CO Ltd 4 Jan 1974 [6 Jan 1973] 00422/74 Heading C2C A process for separating methacrolein from a gaseous mixture containing methacrolein comprises: (1) absorbing the methacrolein in the gaseous mixture with methyl alcohol, ethyl alcohol, iso-propyl alcohol or normalpropyl alcohol, and (2) subjecting the resulting methacrolein-alcohol absorption solution to extractive distillation with water in an extractive distillation zone, wherein said solution is introduced into the middle portion of said zone and the water is caused to flow down from the upper portion of said zone so that the concentration of water in the liquid phase in the absorbing section of said zone is controlled to a concentration in the range from 50 to 90 mole per cent, thereby to recover the methacrolein as the top distillate of said zone and the alcohol with water as the bottom liquid of said zone. The recovered methacrolein/water azeotrope may be separated and part of the methacrolein returned to the column as reflux and the water returned as solvent as may water separated from the bottoms by distillation. The alcohol thus separated may be recycled to stage (1), after dehydration if required. The gaseous mixture containing methacrolein may be derived from the oxidation of isobutylene or may be gas containing unreacted methacrolein from the oxidation of methaorolein to methacrylic acid.

Title: An improved process for the refining of saccharine liquids
IPC: C13B20/00
Filed: 1925-01-06
Abstract: 244,924. Singh, P., and Majithia, S. K. S. Jan. 6, 1925. Purifying saccharine liquids.-Sugar-containing liquids are clarified and bleached by first precipitating aluminium hydroxide therein by adding aluminium sulphate or other suitable aluminium salt and then adding the requisite amount of alkali, such as caustic soda, sodium carbonate or milk of lime, to give a slightly alkaline reaction, and heating preferably to 100‹ C. and separating the precipitated matter. The liquid is then acidified and is boiled with a clarifying and bleaching agent, which will decompose on heating into sulphur dioxide and a metallic hydroxide, and the precipitated matter separated. In some cases the treatment with the clarifying and bleaching agent may be repeated. The sugar-containing liquids may be subjected to preliminary treatment by sieving or other known methods to remove easily eliminated impurities. In the first part of the process the liquid is preferably made alkaline before adding the aluminium sulphate, and before the filtration, kieselguhr or other suitable clayey or like substance may be added to form porous, easily washed filter cakes. The clarifying &c. agent may consist of a suitable metallic hydroxide dissolved or suspended in an aqueous sulphur dioxide solution. In the example given. it is prepared by precipitating aluminium hydroxide from a dilute aluminium sulphate solution with the required amount of caustic soda or sodium carbonate, washing the precipitate almost free from sodium sulphate, and suspend. ing it in water and passing sulphur dioxide therethrough until a clear solution with a strong odour of sulphur dioxide is obtained. This solution is an acid solution of sulphates and contains basic aluminium sulphate Al2 (SO,), 6A1 (OH)3 aluminium sulphite, and a little sodium sulphate.

Title: Improvements in vacuum distillation process and apparatus
IPC: B01D3/10
Filed: 1946-01-05
Abstract: In a process of vacuum distillation, a thin film of the distilland spread centrifugally on a rotating surface within the evacuated chamber, is subjected to radiant heat, harmful contact between the distilling vapours and the source of radiant heat being prevented. This may be effected by enclosing the radiant in a transparent envelope; by allowing a controlled leak to blow the vapours away from it; by arranging baffles for the vapours; or by disposing transparent surfaces between the radiant and the film of distilland, e.g. by placing radiants outside a chamber fitted with windows or by making the condensing surface of transparent material, e.g. quartz.  An auxiliary heater may also heat the vaporizing surface on which the film of distilland is spread.  A radiant heater 34 with a quartz envelope, Fig. 1, heats a film of distilland on the rotating vaporizing surface 8, which is also heated by heater 14.  The vapours are condensed on the cooled annular collars 24 which act as baffles. The radiant heater may further be provided with vapour baffles 110, Fig. 6, and with a controlled leak <PICT:0621791/III/1> <PICT:0621791/III/2> 112 to blow the vapours away from the heater. In modifications, the vaporizing and condensing surfaces both rotate in a vertical plane; radiant heaters are disposed behind a transparent condensing surface; the vaporizing surface is in the form of a rotating truncated cone with stationary baffle-type or lattice-type condensing surfaces and the radiant heater disposed within it; the vaporizing surface is a series of rotating superimposed truncated cones with a stationary radiant heater and baffle reflectors disposed in their axis and stationary condensing surfaces outside them.  Specification 607,019 is referred to.
