Title: Dehydrating starch conversion liquors by evaporation
IPC: C13K1/06
Filed: 1956-10-31
Abstract: Starch conversion liquors, such as corn syrup, having dextrin equivalent values of 30 to 80% are dehydrated by rapidly and continuously passing the liquor under pressure, e.g. 10 to 15 p.s.i.g., through two linear heatexchangers arranged vertically and connected in series at their upper ends, the heat-exchangers being maintained at such temperatures that the liquor is raised to its boiling-point in the first heat-exchanger, and that a substantial part of the water in the liquor is vaporized while the liquor is flowing through the second heatexchanger.  The substantially dehydrated liquid and water-vapour, discharged from the second heat-exchanger, are separated; and the liquid is cooled whereby a clear solid, having a moisture content below about 4%, is obtained. This solid may be milled, giving a non-caking product suitable for the market.  Corn syrup having a moisture content of <PICT:0822748/III/1> about 20% is withdrawn, at a temperature of about 65 DEG  C. from tank 1 by gear-pump 3, and is passed at a pressure of 10 to 15 p.s.i.g. through line 7 into tube 8 which is surrounded by heating-jacket 9.  The rate of flow of the liquor is adjusted by means of by-pass 4.  The liquor then flows through extension 10 into tube 11 which is surrounded by heating-jacket 12. Steam at a pressure of 90 p.s.i.g. is supplied to jackets 9 and 12 through line 13; and condensate and uncondensed steam are withdrawn through line 14 and steam-trap 15.  In an example, tubes 8 and 11 are made of 1.5 inch copper pipe, each being 20 feet long.  The liquor is heated to about 115 DEG  C. in tube 8, but no appreciable vaporization takes place therein.  The liquor is then raised to 120 DEG  C. in tube 11, wherein the water is vaporized from the liquor. Dehydrated liquid and watervapour are discharged through line 16. The liquid and vapour are separated by centrifugal action; and the liquid is cooled, by a cool airstream, to form a solid product with a moisturecontent of 3%.  The internal cross-section of the first tube can be smaller than the internal cross-section of the second tube. In this case, the larger cross-sectional area of the second tube readily accommodates the watervapour which is formed during the dehydration.

Title: Hydraulic shock absorbing device particularly for power driven vehicles

Filed: 1934-11-20
Abstract: 432,333. Hydraulic shock-absorbers. RICHTER, E., 13, Kaiser Friedrichstrasse, Senftenberg, Niederlausitz, Germany. Nov. 20, 1934, No. 33377. Convention date, Nov. 28, 1933. [Class 108 (iii)] An hydraulic shock-absorber particularly for power-driven vehicles comprises two relatively fixed cylinders 5, 6 disposed side by side or in alignment and separated internally by a partition, and corresponding pistons 13, 14 which at their opposite ends abut guide surfaces 18, 19 on an enclosing casing 2, the surfaces 18, 19 being arranged eccentrically to an axis about which the cylinders and casing are adapted to be relatively rotated when a shock occurs. As shown the cylinders are in alignment and carry pins 3, 4 rigidly secured to a fixed member 7, the casing 2 being rotatable about the pins. When a shock occurs liquid is forced, for example, from the cylinder 5 through a manuallyadjustable throttling - orifice 8 into the cylinder 6 and presses the piston 14 outwardly so that it remains in constant contact with the surface 19. The action is reversed on opposite rotation of the casing. The Specification as open to inspection under Sect. 91 comprises also constructions in which the pistons are spring-pressed and the cylinders arranged at an angle to one another and it also states that the cylinders or the casing may be fixed or rotatable. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in wrapping machines
Inventor: BROOK LEONARD
IPC: B65B57/02
Filed: 1955-11-22
Abstract: 795,073. Wrapping machines. FORGROVE MACHINERY CO., Ltd. Oct. 29, 1956 [Nov. 22, 1955], No. 33400/55. Class 94(1). In a wrapping machine having a carrier head for traversing articles through wrapping stations to an ejecting station, a feeler mechanism is associated with the ejector and is responsive to the absence of a wrapper on an article to cause the unwrapped article to be diverted from the discharge shoot. The invention is described as applied to a machine of the kind set forth in Specification 396,212 and having article feeding arrangements as in Specification 728,111, The feeler mechanism comprises feeler arms 26 on a shaft 25 mounted at one end in the ejector arm 20 and at the other in a member 24 secured to the ejector arm shaft 21. Friction means 27- 29 enable the arms 26 to remain in any position. The arms 26 are normally engaged by the twisted ends 119 of the wrapper and pivoted by them so as to enable a pin 32 on the shaft 25 to raise a trip piece 30 clear of an abutment 33 on a lever 34. The trip piece is mounted loosely on the shaft 25 and biased downwards by a spring 31. A fixed stop 39 causes re-setting of the arms 26 during the final part of the ejecting movement of the arm 20. When no wrapper is present to move the arms 26, the piece 30 stays in the path of the abutment 33 and movement of the arm 20 causes anticlockwise pivoting, as shown, of the lever 34. The lever opens a trap door 36 to which it is connected by a rod 35, so that the unwrapped article 14, instead of passing down the discharge shoot 22, is led by a shoot 37 back to the feed wheel (not shown). The diverting operation may additionally actuate a warning signal and/or stop the machine.

Abstract: In the production of a silica-coated, prebulked, continuous filament yarn, an aqueous colloidal silica dispersion is applied to a yarn having latent crimp to deposit 0.1 - 5% silica as a coating on the filaments, the yarn is fed into a heating zone, wherein it is dried and the crimp developed therein, and is then wound into a package at a speed at least 5% less than the feed speed and a tension less than 0.2 g.p.d.  In the apparatus of Fig. 1 (not shown) yarn 20 (which has passed between crimping gears) passes over the periphery of, and receives the silica dispersion from, a slowly and adjustably rotating wheel 36 of an applicator 24, is advanced by nip rolls 26 to a chamber 28 wherein it is simultaneously bulked or dried, and then fed by nip rolls 30 to take-up mechanism 32.  A manual valve-controlled aspirator apparatus 68 facilitates yarn string-up.  The chamber 28, Fig. 2 (not shown) comprises a tube 40 (through which the yarn passes) surrounded by an insulated steam chamber 42 to and from which high-pressure steam is admitted and exhausted by pipes 44 and 46. Steam is also introduced or bled into the tube 40 via restricted orifice 52, expansion chamber 48, and apertures 50 and is withdrawn via an exhaust nozzle 54 the suction in which is controlled by an adjustable valve plate 64.
