Title: Improved process for seasoning timber
IPC: B27K5/00
Filed: 1943-11-24
Abstract: 618,854. Seasoning timber. KOBIOLKE, A. M. Nov. 24, 1943, No. 19614. [Class 140] Timber is stacked in open arrangement in a closed container 10, as by use of a trolley, and then subjected to the following treatments, (a) air is withdrawn through pipe 19 simultaneously with heating the interior of the container by circulating fluid through piping coils 16; (b) suction is maintained, the timber is immersed in water admitted through valve 20a, and this water is heated by steam admitted through inlet 24; (c) 'the vacuum, and the temperature of the water, are increased until the water boils turbulently; (d) the vacuum valve 19a is closed and air is admitted by valve 36 to raise the pressure to atmospheric, thereby causing the water to penetrate into the cells of the timber; (e) the air valve 36 is closed, the water further heated, air exhausted by reopening valve 19a and the water caused to boil turbulently until the tannic salts in the cells of the timber are diluted; (f) the vacuum is closed, the water drawn off and the vacuum valve re-opened, to cause the warm liquid remaining in the cells to boil turbulently; (g) the vacuum valve is closed and cooling fluid is circulated through the coils 16, whereupon vapour given off by the boiling liquid is condensed and the resulting liquid is withdrawn. Simultaneously fans 31, 32 are operated to circulate the vapour; (h) live steam is admitted to warm the timber; (i) the steam is shut off, the vacuum is restored and cooling fluid is passed through the coils and the vacuum is again restored to extract and convert moisture remaining in the timber into vapour and this vapour is circulated by the fans. Pre-heated air is then admitted through the valve 36, circulated in the container and discharged therefrom until the timber is dried to the desired condition; (k) the container is cooled by cooling fluid in the pipes 16 and, finally, the container is opened and the timber withdrawn. Steps (c), (d) and (e) to (h) may be repeated any desired number of times. The temperature in the interior of the timber is never allowed to get unduly high during the treatment, and it is ascertained by means of an indicating instrument 21 connected to a thermocouple 21a in a hole in one of the fletches of timber. The whole process takes many days.

Title: Mobile filter device
IPC: B01D35/143
Filed: 1964-05-12
Abstract: 1,003,463. Filters for liquids. ROSAEN FILTER CO. May 12, 1964 [May 13, 1963 (2) ; Jan. 27, 1964 (2)], No. 19649/64. Heading BID. A filter element 68, Fig. 1, is secured to a rod 58 slidable in a boss 56, the element thereby being slidable in a tube 22, the latter being clamped by a ring 24 welded to a base plate 26 secured to the top of a reservoir 10. Downward movement of rod 58 is limited by a snap ring 59. On partial clogging, the element, the rod 58 and a slotted arm member 90 rise against the pessure of a spring 74, a pointer 82 being rotated by interaction of arm member 90 with an actuator member 88 carried by the pointer, and thereby indicating the clogged condition. On further clogging, a valve 78 is lifted against the pressure of a spring 80, enabling bypassing of the filter element. The filtrate outlet 92 is connected by a conduit 94 with the intake of a pump 14 ; conduit 94 serves to support housing structure 46 so that when bolts 100 are removed, flange 50 (integral with flange 98 and structure 46), rod 58 and filter element 68 may be withdrawn from the reservoir as a unit leaving tube 22 clamped in position. Other embodiments (not shown): in Fig. 5, flange 50 is screwed to tube 22 ; in Fig. 6, flange 50 is integral with tube 22 ; in Fig. 7, the filter element extends to a point below tube 22 ; in Fig. 8, spring 80 is omitted, the valve member is fixed on rod 58, and the filter element slides along the valve member as well as along the inside of tube 22 ; Fig. 12 has the features of Fig. 8, but flange 50 is integral with tube 22. In Fig. 15, a tube 722 has secured to it a collar 724 by which it may be positioned on the cover plate 416 of a reservoir. A cap 746 has an integral boss 756 carrying a rod 758. A member 768 is held against a shoulder 757 on the boss 756 by a filter cartridge 764. Liquid filtering inwards through the cartridge passes upwards through holes 769 in member 768 and out through port 706. On clogging, a piston member 772 sliding both on interior face 771 (tube 722), and on exterior face 770 (member 768), rises to uncover openings 773 in member 768 to permit by-passing. An indicator assembly 775 is provided.

Abstract: 375,092. Automatic regulation- ALLM€NNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. July 10, 1931, No. 19892. Convention date, July 15, 1930. [Class 38 (iv).] Voltage regulators for three-phase generators are so compounded as to maintain the " right-away voltage star " (positive phase sequence component of the generator voltage) under unbalanced load conditions. For this purpose a voltage from corresponding impedances Ks traversed by current in the two phases 2, 3 from which the potential applied to the regulator R is derived is introduced into one regulator circuit. The impedances are so chosen that their phase angles have a mutual difference of 60 degrees whilst their numerical values are equal. Portions of these impedances may be common. The voltage drop in the machine itself may be compensated for by further impedances Kg and these impedances may be combined with others K1 effecting external or line compounding. The regulator may also be connected in series with impedances traversed by currents proportional to the neutral point currents and compensating for the effect of such currents on the main regulation.

Title: An improved process for the manufacture of moulded articles of refractory or ceramic material
IPC: B28B1/26
Filed: 1947-07-25
Abstract: 668,266. Electrolysis. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY & CIREY. July 25, 1947 [July 26, 1946], No. 20155/47. Class 41. [Also in Group V] A process for the manufacture of moulded articles of refractory or ceramic material comprises casting slip in a mould and causing the slip to flocculate en masse by passing an electric current therethrough. The slip 3 is prepared from a stiff paste of clay &c. and water, to which is added a peptizing agent such as an alkali hydroxide carbonate or silicate or diethylamine, or for finely-ground refractory oxides the added substances are generally deflocculants having an acid reaction. A stabilizing colloid may also be used to prepare the slip. Electric current when passed between a metal plate 5 on a moisture-absorbent mould 2, Fig. 1, and a perforated metal plate 4 on a plaster core 1, converts the deflocculating agent in the slip into products either not having a deflocculating action or having a definite flocculating action, thus resulting in the flocculation of the slip. Sodium chloride may be used as an electrolyte, and by varying the current it is possible to regulate the moulding time. In addition to direct current an alternating current may be used producing only a rise in temperature of the slip to assist the flocculation. The electrolytic action of direct current may cause gassing at one or both electrodes, and modifications of the apparatus employing bubble collecting sprues and different forms and numbers of electrodes are described with reference to Figs. 2, 3 (not shown). A further modification employing an external conducting liquid able to transfer ions to the slip thus giving an auxiliary flocculating action is also described with reference to Fig. 4 (not shown).
