Abstract: 1,049,699. Dough-dividing machine. BAKER PERKINS Ltd. May 7, 1965 [May 7, 1964], No. 18991/64. Heading B5A. A dividing machine of the type in which dough or dough-like plastic material from a hopper 1 enters a top box 2 and is sheared from the dough mass in the hopper by a reciprocable knife blade 3 and compacted by a reciprocable compactor ram 4 into a dividing chamber 6 aligned with a discharge opening 8 in the top box, after which the division box 5 containing the dividing chamber is moved to bring the chamber out of communication with the top box and the dough slug ejected by an ejector ram 7 in the chamber, is characterized in that the ejector ram is adapted to move against the incoming dough when the dividing chamber moves or has moved out of alignment with the discharge opening, but whilst the chamber is still in communication with the top box, whereby either the dough is further compacted or some of it is extruded back into the top box. The compactor ram may deliver a quantity of dough to the dividing chamber in excess of that required for the final dough slug. In the embodiment shown, a roller 9 is fixed to the end of the ejector ram and as the division box moves, the roller moves over a cam track 10 on an abutment member 11 causing the ejector ram to move inwards towards the top box. The abutment member 11 may be pivoted.

Title: Product handling system for cooling beds
IPC: B21B39/00
Filed: 1972-04-25
Abstract: 1393966 Cooling beds MORGAN CONSTRUCTION CO 25 April 1972 [26 April 1971] 19085/72 Heading B3M [Also in Division B8] Rolled bars 4a are delivered by reciprocating conveyer rack members 110 to conveyer chains 6. After a predetermined number of bars have been fed, the chains 6 are accelerated so as to bring the bars to a position A. A conveyer having chains 32 is then lifted (by the action of crank mechanism 44 and an inclined plane 54) so as to pick up the bars at A and feed them to a position B. Here they are lowered on to chains 60 of a conveyer similar to the conveyer having the chains 32. The latter are then lifted and carry the rods on to grooves of a run-off roll 8. Rotation of the latter brings the leading ends of the rods against a stop 84. The latter is then raised and the rods proceed to a position (Fig. 6) in which the ends of the rods are sheared by tools 86, 88. A support surface 90 (Figs. 2 and 8) adjacent each roll 8 can be adjusted so as to present any one of 3 faces, each of which is partitioned according to the particular diameter of bars 4a being handled. The chain 6, comprises a series of links 20, 22 (Figs. 3 and 4), each of which carries a roller 24 which bears on a support rail 18. Each link 20, 22, is formed with respective dogs 26, 28, which provide location for the rods. Larger rods 4b may be disposed with a vacant location between each rodsupporting location. The lateral extremities of each link 20, 22, are supported by rails 27, 29. The latter extends the whole length of the loadcarrying run of each chain. The chains 32 and 60 are of similar construction to the chain 6, but are supported respectively by rails 42 and 70. The crank mechanism 44 and plane 54, act on the rail 42. Similar mechanism acts on the rail 70 when it is necessary to lift the chain 60. In a modification, one of the two chains 32, 60, is dispensed with.

Title: Arrangement for the electrical long distance control of the valve gear of a hydraulic gun pointing gear
IPC: E01H3/02
Filed: 1920-07-07
Abstract: 147,126. Krupp Akt.-Ges., F. Nov. 27, 1916, [Convention date]. Mountings.-Relates to electric long-distance control of the valve-gear of hydraulic gunlaying apparatus, and consists in providing in combination (1) an Hydraulic valve E which is opened to impart movement to the gun by operating an electric receiving-motor G from a distant transmitter H, and closed, when the gun has moved through the prescribed angle, by gearing connecting it with the gun barrel A, and (2) cut-off valves Band C in the pressure pipes, the opening and closing of these valves being effected in accordance with the mutual angular positions of the receiver G and gun A. The invention is shown applied to elevating-gear although it may be applied to training-gear. The elevating-gear comprises an hydraulic piston and cylinder device a<2>, A<3> fed by pressure pipes a<4>, a<5> leading by way of the cut-off valves B, C to a controlling piston-valve E moving in a valve-box having a pressure pipe e<1> and exhaust pipe e<2>. The valve E is connected through a rack e<7> to a sector-lever f<19> moving in a box F shown in detail in Fig. 2. The lever f<19> carries a spring-pressed roller f<16> engaging a two-diameter spiral rib f<13>, f<14> on a drum which is rotated through differential gear f<10>. f<11>, f<12> and wormgears f<3>, f<5> on the one hand by movements of the shaft g<1> of the receiver G, and on the other hand by movements of the shaft f<8> geared to the gun barrel A. The receiver G is rotated synchronously with a transmitter H set through a differential gear h<3>, h<4>, h<5> on the one hand by a ranging hand-wheel h<1> and on the other hand by a handwheel h<2> which is rotated, to correct for the roll of the ship, so as to keep the horizon in the view of a telescope h<9>. When the gun has moved to accord with the receiver G, the roller f<16> is in neutral position on the transition portion f<15> of the spiral rib and a switch arm f<21>, connected to a conductor k<4>, is situated between a pair of electric contacts connected to conductors k<7>, k<8> these conductors forming part of a circuit through the solenoids b<4>, c<4> actuating the cut-off valves. Movements of the roller in one direction or the other from its neutral position, cause the contact f<21> to close electric circuits through the solenoids b<4>, c<4> to open the valves B, C against the action of springs b<2>, c<2>. When the prescribed movement of the gun has taken place, the valve E is returned to central position, and the circuits through the solenoids are broken to enable the cut-off valves to close. When the cut-off valves are in closed position, and the switch K' is open, a piston-valve D can be operated by the handwheel d' to bring the gun to the horizontal position for loading, the gun being automatically returned to the elevation prescribed by the receiver G after the gun has been loaded and switch K<1> closed.

Title: Improvements in cigars, cigarillos, and similar articles
Inventor: PLATT BERTIE CECIL
IPC: A24B15/10
Filed: 1963-05-15
Abstract: A method of treating a cigar to obtain a uniform colour comprises applying successive coatings of a mixture of powdered tobacco first with adhesive and then with uroxy extracts and removing the solvent after each coating.  The extracts are prepared by grinding the tobacco coarsely adding water to remove sugars and other water soluble materials, drying the tobacco adding ethanol, boiling, extracting and filtering.  A second quantity of ethanol is added to the tobacco and a second extract filtered off.  The extract is concentrated by distillation, filtered, chilled and centrifuged to separate the uroxy component which is washed with ethanol, heated in a partial vacuum to remove the ethanol and dissolved in petrol.  The liquor is filtered, diluted and finally ground tobacco is added, providing the adhesive solution.  The solution may be added by spraying on to a cigar held by rotating pins on a conveyer belt or by passing the cigar between pairs of rotating resilient rollers coated with extracts, or by brushing or dipping the cigar.  The coarse tobacco may be initially treated with boiling petrol before adding the boiling ethanol.  The adhesive extract may be obtained by adding ethanol to coarse tobacco stirring and filtering.  The coarse tobacco may be extracted with petrol, distilled, chilled and centrifuged and fractionated on a chromatic graphic column of alumina.  Fractions are treated by heating with ethanolic potassium hydroxide, cooling, diluting and acidifying followed by extraction with ether.  After evaporation the extract is dissolved in ethanol and finely ground tobacco added which has been denicotinised with ethylene oxide.

Patent GB-711160-A (GB)
Title: Improvements in or relating to process for producing acrylonitrile
Filed: 1951-08-16
Abstract: Acrylonitrile is prepared by reacting hydrocyanic acid and an excess of acetylene in an acid cuprous halide solution forming a gaseous mixture of crude acrylonitrile containing sparingly water-soluble polymerizable impurities, partially condensing the gaseous mixture to obtain a liquid condensate containing a portion of said impurities and a portion, preferably 20 to 60 per cent, of the acrylonitrile present in the gaseous mixture, adding to the condensate water or other inert solvent for the acrylonitrile in which the polymerizable impurities are only sparingly soluble, separating a solution of the solvent containing substantially all of the acrylonitrile and a minor proportion of the polymerizable impurities present in the condensate and then contacting this solution with a stream of gaseous acetylene to strip therefrom the residual polymerizable impurities and leave a solution of purified acrylonitrile.  Preferably, the gaseous product mixture is partially condensed at -3 DEG  to 18 DEG  C. and the liquid condensate mixed with water whereby an aqueous extract of acrylonitrile and an organic phase comprising chlorobutadiene, mono- and di-vinyl acetylenes and vinyl chloride are formed.  The aqueous extract is then treated with gaseous acetylene in a fractionating absorber to strip off the residual impurities.  Water is introduced at the top to scrub the issuing vapours of acetylene and said impurities, the washed gases then being fed to the acrylonitrile reactor while acrylonitrile solution containing only such less readily polymerizable impurities as acetaldehyde, lactonitrile and cyanobutadiene is withdrawn from the base of the absorber.  The uncondensed portion of the original gaseous mixture may be simultaneously treated in the absorber or may be scrubbed with water and the resulting aqueous acrylonitrile solution scrubbed with acetylene.  Specification 695,636 is referred to.
