Title: Method of and apparatus for restacking bricks, particularly sand-lime bricks
Inventor: LEIDING GERNOT
IPC: B65G67/14
Filed: 1966-03-10
Abstract: 1,145,321. Stacking, unstacking and banding bricks; brick grippers. ATLAS-WERKE G.m.b.H. 10 March, 1966, No. 10587/66. Headings B8C and B8H. [Also in Division B7] An apparatus for packaging bricks supplied stacked on kiln trucks, the stacks being of uniform length but varying in width from top to bottom, comprises means to remove single or multiple layers and arrange them as a line of a width equal to the stack length, and means to separate groups progressively from the line to form layers of a stack. Vertical stack layers, one brick deep may be banded to form packets. In one embodiment, the truck 3, Fig. 11, 12, may be unloaded in two operations by horizontally movable gripper jaws 7<SP>1</SP>a, 7<SP>1</SP>b which engage five layers simultaneously and deposit them on a conveyer 9<SP>1</SP>. The so-formed line 6<SP>1</SP> moves up to stops 11<SP>1</SP>, see also Fig. 12 (not shown), where a portion ten bricks wide rests on a roller platform. The latter is drawn to the right, as shown, to separate the portion from the line and a horizontal pusher 14<SP>1</SP> forwards the group to a banding machine 2 where each vertical layer is separately bound. The packets move on to a further pusher 33 which transfers them to another conveyer 32 for loading on a lorry &c. In another embodiment, a gripper head removes a layer at a time by engaging it between two horizontally movable jaws in the form of bars 7a, 7b, Fig. 6. Bars 17a-c which are caused to descend by the grippers as each layer is removed, rest in the vertical gaps in the stack to prevent the bricks of the layer below  that being moved, from closing up when the latter is engaged by the grippers. The layers form a line on a conveyer and move on to a sliding support 10a above a platform 12, Fig. 7. The platform descends a layer thickness every time the support is withdrawn to permit a layer formed by the advancing line, to fall upon it. A stack is thus built up on the platform which is pushed on to a discharge conveyer carrying it through the bander 2. In a further embodiment, Figs. 13-17 (not shown), the entire apparatus may be mounted on a truck (37), the gripper being pivoted to swing from a position above a stack to one above a conveyer (9<SP>11</SP>) carrying layers to a stacking support (12<SP>11</SP>) as previously described. In this embodiment, the support turns through 90 degrees before the stack is removed to reorientate the bricks for banding. The packets are pushed on to empty kiln trucks.

Abstract: 881,682. Liquid fuel burners. PORTES J. G., and MARSOT, C. L. March 25, 1960 [March 25, 1959], No. 10707/60. Class 75(1) [Also in Group XVII] A burner nozzle for burning a mixture of finely divided liquid fuel and air comprises a cylindrical neck 1 2  having a convergent inlet 1 1  for secondary air and a coaxial tubular section 1 3  downstream of the neck and connected thereto by a transverse surface 1 4 , a sharp edge 15 being formed at the joint between the transverse surface and the neck. The tubular section 1 3  is terminated at its downstream end by a further sharp edge 16. A mixture of liquid fuel and primary air is discharged into the neck 1 2  from an end orifice 2 1 , of an injector comprising a pipe 2 supplied with air at a pressure of 0À2 to 0À6 kg./cm2 and with fuel by a thin conduit 4 having an open end disposed in the pipe 2 near the discharge orifice 2 1 . For low rates of fuel feed the open end of the fuel conduit 4 faces the discharge orifice 2 1  ; for greater rates the open end faces across the pipe 2; and for still greater rates a number of fuel conduits 4 are provided. An alternative form of mixture injector is shown in Fig. 5 and comprises two coaxial tubes each having an end discharge orifice. Fuel or air is supplied to the annular passage 34 between the tubes and air or fuel to the inner tube 36. A bellmouth 37 joined to a cylindrical outlet 38 is disposed around the downstream portion of the nozzle and supplies tertiary air. A bellmouth 8 may be fitted to the upstream end of the nozzle. In Fig. 6 which shows a boiler 10 heated by the burner the primary air is supplied to the injector by a pipe 3 and a valve 27 from a compressor 11. The fuel is supplied to the injector by a pipe 5 from a float chamber 17 supplied through a valve 28 from a fuel tank 14. The compressor also supplies air to the top of the float chamber and to the top of the fuel tank. The rate of flow of fuel to the burner is controlled by raising and lowering the float chamber which is secured to the end of a pivoted arm 21, the other end of which carries a weight 23 and is connected by a chain 24 adapted to be moved manually or by a thermostat 25. The float chamber may be slidable along a vertical guide. The fuel and air can be cut off simultaneously by a double cock 26, Fig. 1, or the ratio of fuel and air can be regulated simultaneously whilst maintaining constant the pressure difference between the air and fuel by two cocks 39, 40. The closure cap, Fig. 7, for the filling aperture 30, of the fuel tank 14 is formed in two parts 31 1  and 31 2  connected by a spring 32. The upper part has two wings 33 of unequal weight which tilt the cap except when it is tightly closing the aperture.
Patent GB-107093-A (GB)
IPC: H02J3/26
Abstract: 107,093. British Thomson-Houston Co. (General Electric Co.). July 11. 1916. Balancing; boosting; regulation, automatic systems and apparatus for. -In a phase balancing system for polyphase circuits the booster field coils of the phase balancer have relatively displaced portions and the magnitude and direction of the exciting voltages on these portions is controlled by a vibrating regulator. A threephase system is supplied bv the generator 1 and single phase loads are connected to the phases A, B. The phase balancer set consists of a synchronous machine 2 and a booster 5. The relatively displaced portions 6, 7 of the booster fields are supplied from exciters 16, 17 with field coils 18, 19 which are connected to points on regulator resistances shunted across the outer leads 11, 13 of a three wire generator 10. The resistances consist of three sections R<1>, R<2>, R<3>, the section R<1> being greater than the section R<2> but less than the sections R<2>, R<3> combined. The section R<3> of one set is controlled by a regulator 26, the coil of which is connected in parallel with the anti-hunting coil 24 of the vibrating regulator 20 and across the contacts 21, 22. The coils 24, 26 are connected in the circuit as shown so that the voltage on them is the algebraic sum of the voltage of the exciter 16 and the voltage between the lines of the generator 10. The coil 23 of the regulator 20 is responsive to the voltage on phase A. A similar arraugement of regulators is used in connexion with the exciter 17 the coil 33 being connected across phase B. When the resistances R<3> are short circuited, current flows from the line 13 through the exciter fields 18, 19 to the line 12, while when the resistances are in circuit the current flows in the reverse direction through the fields from the line 12 to the line 11. The direction of the exciter current therefore depends on the relative times of open and closed regulator contacts, and the regulators act to keep the voltages on the phases A, B at a constant value determined by the weights 20 on the contact arms. In a modification, the weights are replaced by coils connected across the third phase of the supply.

Title: A process for fractionating mixtures of fatty acids and/or esters of fatty acids
IPC: C11C1/00
Filed: 1939-04-11
Abstract: 541,002. Separation of fatty acids and esters. KAUFMANN H. P. April 11, 1939, No. 110,16. [Class 91] Mixtures of fatty acids, fatty oxy-acids, keto acids, polymerized acids and estolides are separated into their constituents by .allowing the mixtures or solutions thereof to flow through a thick layer of adsorbent substance, the amount of adsorbent being at least half the quantity of the fatty substances and, if necessary, a multiple thereof. The process is one of chromatographic adsorption. Adsorbents mentioned include alumina, bleaching earths, carbon, gypsum, calcium carbonate, magnesium oxide and fibous clay. In examples (1) a benzene solution of a mixture of stearic and myristic acids is passed through a column of aluminium oxide. The stearic acid is absorbed and the liquid which passes,through is pure myristic acid. (2) A mixture of stearic and oleic acid treated as in example (1) yields an absorbate of pure oleic acid. (3) Stearic, oleic and linoleic acids are treated as in example (1) to give an adsorbate free from stearic acid. (4) A benzene solution of whale oil fatty acids gives an adsorbate richer in unsaturated acids the the starting material.

Patent GB-865850-A (GB)
Title: Preparation of mercaptans
Filed: 1959-04-01
Abstract: Mercaptans are prepared by reacting an ether of formula R-O-R1, where R and R1 are hydrocarbon groups which contain an aliphatic carbon atom at the point of attachment to the ether oxygen, or a primary or secondary alcohol having at least 3 carbon <FORM:0865850/IV (b)/1> atoms and containing the group with hydrogen sulphide in the presence of a solid oxygen-containing acidic catalyst, the reaction being carried out at an elevated temperature, e.g. 100-500 DEG C., and, in the case of an alcohol reactant, at a pressure of at least 50 psig. Elevated pressures are preferably used with ethers also.  The molar ratio of H2S to alcohol or ether may be up to 10:1 or higher. Suitable catalysts include oxides and oxyacids of boron, silicon, sulphur and phosphorus, e.g. phosphoric acid/kieselguhr, or silica promoted with an oxide of a group IIIB metal, e.g. alumina or beryllia, preferably in an amount of 1-20%.  Fixed or fluidised beds may be used.  The alcohols and ethers may be aliphatic, cycloaliphatic or arylaliphatic.  Primary alcohols yield secondary mercaptans, the mercaptan group being introduced on the carbon atom a to that originally carrying the hydroxyl.  This isomerism also occurs with secondary alcohols unless both a -carbons are terminal when the mercaptan group merely replaces the hydroxy, or unless the symmetry of the molecule means that the same product is formed in either case. Examples describe the conversion of n-propanol to isopropyl mercaptan, isopropanol to isopropyl mercaptan, sec-butanol to sec-butyl mercaptan, sec-amyl alcohol to sec-amyl mercaptan, n-dodecanol to secondary dodecyl mercaptan, diisopropyl ether to isopropyl mercaptan and cyclohexylethyl ether to cyclohexyl and ethyl mercaptans.
