Title: Solid-liquid packed bed extraction
IPC: G08C25/00
Filed: 1973-01-01
Abstract: 1420771 Extracting solids GENERAL FOODS CORP 1 Jan 1973 128/73 Heading B1Q A bed of vegetable or animal materials has soluble constituents extracted from it by solvent under such controlled conditions that the viscosity of the liquid decreases in the direction of flow of liquid. This may be accomplished for example by a temperature gradient through the length of the bed or through solvent additives such as gums. The bed may be stationary or moving or may have upward or downward flow of liquid. The process can be batch or continuous. The extraction may be conducted in plural stages. The embodiment of the process in which there is a temperature gradient may be conducted by heating the bed or heating the materials before they are fed to the bed.  A column with upward fluid flow has two electrodes 10 which with suitable electrical potential cause a positive temperature gradient due to the increasing soluble content in the liquid in the direction of flow. A number of distribution devices are described in relation to Figs. 3 and 4 (not shown).

Title: Improvements in or relating to mechanism for opening and ejecting the contents of boxes
IPC: B65B69/00
Filed: 1942-01-12
Abstract: 552,783. Opening boxes and delivering the contents thereof. HALL, C. T., and MOLINS MACHINE CO., Ltd. Jan. 12, 1942, No. 435. [Class 94 (i)] Tubular containers of cardboard &c. in which at least one end is closed by a flap having a portion folded so as to lie within and against the tube, and containing, e.g. links for machine-gun cartridge belts, are stacked vertically in a magazine 6, Figs 1A and 2, from the bottom of which they are pushed individually by a pusher 8 actuated from main shaft 17, Fig. 1B, through a crown cam 16 actuating an extension 14 on a lever 10 forming one of a pair 9, 10 pivoted at 11 in the main frame and secured at the upper ends to the pusher 8. When the container is in the ejected position two hook members 35, Fig. 7, emerge, enter the ends of the container and engage the flaps by the hooks, the return movement withdrawing the flaps as indicated in Fig. 4. Members 35 are actuated from a threearmed lever 31, 33, 43, Figs. 1A and 2, one by connection with an arm 34 of a bell-crank lever 34, 38, and the other by connection with arm 43 of the three-armed lever through lever 40 pivoted to the frame at 41 and link 42. When the hook members 35 are withdrawn the feeding forward of the succeeding container brings the first container in the path of a pusher 27 actuated from the main shaft 17 through cam 19, roller 20, lever 21, link 23, slide 24 and rod 26, thus ejecting the contents to a shoot 2. The top guides 5 on the table 4 on which the containers rest are hinged so that they may be raised to give access to a container if it jams, the mechanism being meanwhile stopped by disengaging a pin 62 carried by a handwheel 63 from engagement with one of a series of holes in a driven sprocket 61 on mainshaft 17. An electrical stop-motion may be embodied in which a feeler 73, Fig. 12, normally rests in a withdrawn flap of a container, but which moves on its pivot 72 when no flap is present, permitting stud 74 of a " microswitch "-in which only a very small movement takes place in closing the switch-to move and break the circuit of the motor driving the main shaft. To prevent egress of the contents of the containers when the flaps are being opened needles 67 carried on arms 46, 44 actuated from the bell-crank levers penetrate the material of the containers and act as stops for the contents. Specification 539,184, [Group XXI], is referred to.

Abstract: 854,500. Mineral-coated paper &c. WARREN CO., S. D. Jan. 4, 1957 [Jan. 16, 1956; Sept. 18, 1956], No. 468/57. Class 96. In the production of high-gloss, mineralcoated paper, which may be cast-coated or not, the coating mixture, e.g. made by adding casein, dicyandiamide, calcium carbonate, aluminium sulphate, tartaric acid, ammonia, a silicone antifoaming agent, a styrene-butadiene copolymer, hexadecylketene, sodium stearate, and gum ghatti, is applied from a bath 2 adjacent to an air-knife K, the coated side of the paper being thereafter treated with formic acid in a bath 4 and the paper passed to a nip N between a soft rubber roll 6, and a polished drying cylinder 5 heated above the boiling point of the water &c. of the coating composition, e.g. to 130‹ C., the nip pressure being 400 1b. per linear inch, and its width 1¢ inches. The formic acid acts as a gelling agent so that water driven off by the cylinder 5 does not disrupt the coating. Other coating ingredients include soya protein, styrene - maleic - anhydride, styrene - butadieneacrylonitrile, polyvinyl alcohol, clay, Rochelle salt, tributyl phosphate, zinc sulphate and sodium aluminate. Other gelling agents include acetic, or a mineral acid, ammonium borate, or ammonium bisulphate; or the coating may be set by driving off ammonia by steam, or it may be reacted with multivalent metal ions. In other modifications, both sides of the paper may be coated, and hard rolls used for the nip N which may be followed by a hot air, tunnel drier; or radiant heat may be used ; water may drip into the nip N. Specification 854,501 is referred to.

Title: Improvements in touch-welding devices
IPC: B23K9/14
Filed: 1951-01-08
Abstract: 682,224. Uniting by fusion. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 8, 1951 [Jan. 11, 1950], No.525/51. Class 83 (iv). In an automatic touchwelding machine, the consumed electrode is lifted from the work after a welding operation by a source of stored energy (e.g. a spring), which is released by an electromagnetic relay, the coil of which is short-circuited when the relay is energized. As applied to a continuous welding machine using a number of electrodes 5, 6, &c., Fig. 1, in succession, each electrode is supported by a holder such as 1 supplied with welding current by the circuit 7 ... 12 and supported between rollers 21 on a base 15 so that the electrode is held against the work 10 by gravity. To start a welding cycle, a lever 23, Fig. 2, is raised by hand, whereby a slot 26 therein acting on a pin 27, depresses a block 28 slidable on rods 29 on the base. A block 34, also slidable on rods 29, is attached to block 28 by a spring 35 and when block 34 engages a stop 30 it slides within horns 31 on block 28 and the spring 35 is compressed. Towards the end of the movement a stud 33 on block 28 engages a tongue 40 on the armature 42 of the relay 17, raising the armature clear of the relay coil against spring action. The block 28 is latched in the lower position by stud 33 engaging a stop 44. Welding then proceeds by electrode 5, and when this has been consumed, the arc is transferred to the next electrode 6 through the fusing of the insulating coating of electrode 6 or the fusing of insulation 13 on which a bare electrode 6 rests. The circuit to electrode 6 is completed through wire 16, the coil of relay 17 and wire 14 so that starting of electrode 6 energizes the coil to attract armature 42 and release the block 28, the armature in its closed position causing contacts to short-circuit the coil so that it ceases to carry the welding current. A spring 24 raises the lever 23 and block, the spring 35 holding block 34 against the stop 30 and relative motion between blocks 28, 34 causes rollers 36, eccentrically pivoted at 37 on block 34 and having pins 38 engaging slots 32 on block 28, to rotate and grip the holder 1. The spring 24 then raises both blocks 28, 34 and the holder 1 to remove the consumed electrode 5 clear of the work. After replacing the electrode 5, the holder 1 &c. may be moved in front of the other electrodes to continue the weld in its turn.

Filed: 1937-01-09
Abstract: Monoglucosides of polyhydroxy-flavones or -flavonones are prepared by reacting an alkali metal compound of a polyhydroxy-flavone or flavonone or a partly etherified derivative thereof with an acetohalogenose and if desired, saponifying the product. Alternatively, the appropriate polyhydroxy - o  - benzal - acetophenone (polyhydroxy - chalcone) or partly etherified derivative thereof is converted into a monoglucoside by reacting its alkali metal compound with an acetohalogenose and the product then transformed by a known synthetic method into the corresponding flavone or flavonone compound.  The products possess physiological properties.  Examples describe the preparation of (1) 41-methoxy-7-hydroxy-flavone glucoside by (a) treating 41-methoxy-7-hydroxy-flavone in caustic soda solution with acetobromoglucose and saponifying the resulting tetra-acetyl-glucoside with concentrated caustic potash solution; or (b) reacting acetobromoglucose with 21 : 41 - dihydroxy - 4-methoxy-chalcone dissolved in caustic potash solution, acetylating the resulting tetra-acetylglucoside with acetic anhydride to give 21-acetoxy - 4 - methoxy - 41 - (tetra - acetylglucoside)-chalcone, treating with bromine to form the dibromide, and finally effecting ring closure and elimination of the acetyl groups by means of concentrated potash lye; (2) galangin glucoside by interaction of galangin with acetobromoglucose in caustic soda solution, followed by saponification of the isolated product with concentrated caustic soda solution; (3) eriodictyol glucoside by first forming the tetra-acetyl compound by reaction with acetobromoglucose in caustic soda solution and then saponifying.  The formul  of the products are given.  The Provisional Specification states that acetyl-glucose may replace the acetobromglucose.  The sample furnished under Sect. 2 (5) consists of eriodictyol cellobioside, prepared by treating a caustic soda solution of eriodictyol with acetobromocellobiose, isolating the heptaacetyl compound formed, and saponifying it by means of a methanol solution of sodium.
