Title: Improvements in or relating to automatic devices for the dipping of candles
IPC: C11C5/02
Filed: 1965-01-28
Abstract: 1,061,841. Forming candles by dipping. LILJEHOLMENS STEARINFABRIKS A.B. Jan. 28, 1965 [Feb. 7, 1964], No. 3791/65. Heading B5A. In manufacturing candles by dipping loaded wick lengths into a container of molten candle composition, a device is provided for adjusting the depth of immersion of the wicks. Loaded wick lengths 3 are fastened to a frame 4 carried by a holder 5 and several frames move on a conveyer mounted on the ceiling. One section, 8, of the conveyer is fastened to a dipping arm 7 slidably mounted on a stand 9 and when a frame moves on to this section the arm is caused to move down by means of a compression cylinder 11 to dip the wicks into molten wax in a container 1. Movement of the arm is arrested by contact of an adjustment wheel 13 on the arm with a stop 14 on the stand, the adjustment wheel having a radius decreasing continuously or step-by-step in the direction of turning. The arm is then moved back up and another frame passes on to the section 8 and the process is repeated. When all the frames have been dipped once, i.e. one dipping cycle is completed, the wheel 13 is turned through one turning unit by means of a handle 24 through gears 20, 21 so that in the next dipping cycle the radius of the wheel at the point contacting the stop 14 is smaller than before and thus the wicks are dipped further into the molten wax. The cycle is repeated until the wheel has been turned through all the turning units.

Title: Improvements in or relating to lubricating grease compositions
IPC: C10M169/00
Filed: 1952-02-13
Abstract: A lubricating grease composition, particularly suitable for lubricating ball and roller bearings and having good thermal stability, comprises a lubricating oil thickened with a sodium soap of a fatty material containing at least 70 per cent (based on the fatty material) of myristic acid, together with minor proportions of N,N1-diphenyl-p-phenylene diamine and of an oilsoluble ester of a phosphorus acid.  The lubricating oil may be a mineral oil fraction, an animal or vegetable oil such as lard oil, corn oil or castor oil, or a synthetic oil obtained by polymerization or chemical condensation, or mixtures of these. The sodium soap may be prepared by saponifying a mixture of low molecular weight fatty acids comprising at least 70 per cent myristic acid and/or of the corresponding glycerides, especially with a small excess of caustic soda.  Phosphorus acid esters mentioned are tri-alkyl, aryl and mixed alkylaryl esters of phosphoric and phosphorous acids, particularly tributyl, tricresyl and trixylyl phosphates and triamyl, tricresyl and trixylyl phosphites.  The N,N1-diphenyl-p-phenylene diamine may be dissolved in the phosphorus acid ester and the solution added to the thickened lubricating oil.  Such a solution may be added to lubricating oils thickened with other soaps, for example lithium, calcium, barium and mixed base soaps.  In preparing the thickened lubricating oils containing sodium myristate, the fatty material may be saponified with caustic soda in presence of a portion of the lubricating oil, the resulting composition dehydrated by heating, and the remainder of the lubricating oil then added.  In examples, lubricating grease compositions are described which consist of a blend of distillate and residual mineral oils, sodium myristate, tricresyl phosphate, N,N1-diphenyl-p-phenylene diamine and free caustic soda.  For comparison purposes, similar lubricating grease compositions are described wherein the tricresyl phosphate is omitted and, if desired, the N,N1-diphenyl-p-phenylene diamine is replaced by diphenylamine.

Title: Improvements in cutting torches
IPC: F23D14/46
Filed: 1920-02-09
Abstract: 163,422. Godfrey, A. Feb. 9, 1920. Stops, adjustable.-In an oxyacetylene cutting-machine of the general type described in Specification 130,450, the movement of a handle to bring the cutting torch into the operative position opens cut-off valves controlling the oxygen and acetylene supplies and actuates an electric ignition device for the heating flame. In the construction shown, the shaft 5 of the handle 4 raises and lowers the cutter head through rack and pinion gearing and carries a cam formed with cam surfaces 36, 51. The cam surface 36 operates through a spring-pressed lever 37, a link 90, and a lever 61 the oxygen and acetylene cut-off valves 10, 13 which are geared together by toothed segments 26, 27. The cam surface 51 actuate the electric ignition device just before the cut-off valves are opened, a well on the cam face 51 allowing the sparking to continue long enough to ignite the gases. The oxygen and acetylene cut-off valves 10, 13 may be closed when the cutter head is in the lowered position by means of a handle 67 on the stem of the valve 10. The heating oxygen and acetylene supplies are regulated by means of needle valves 14, 63 operated by knurled heads 91 and pass through pipes 68, 69 to the mixing chamber of the burner nozzle 100. The cutting oxygen supply passes through the pipe 71 to the burner nozzle and is controlled by a spring valve 15 operated by an arm 34 which is held in the open position by engagement with a notch in a pivoted pawl 64. An abutment 66 on the link 90 disengages the pawl 64 from the arm 34 when the cut-off valves 10, 13 are closed, thus allowing the valve 15 to close also. According to one Provisional Specification, the cutting oxygen valve may be operated by a snail cam on a lever arm.

Title: Improvements in and relating to installations for repeating indications of movement at a distance
IPC: G08C19/02
Filed: 1926-02-11
Abstract: 265,012. Evershed & Vignoles, Ltd., and Midworth, C. Feb. 11, 1926. Selective signalling apparatus. - In a system for repeating at remote points the movements of a primary member, a number of distant instruments is connected in series with a master instrument which co-operates with the primary member in a manner such as to constitute a follow-up device and vary the flow of current in the indicating circuit. As shown in Fig. 1, the primary member 1 carries a contact 3 which cooperates, according to the direction of movement, with one or other of the contacts 4, 5 on the pointer 6 of a master instrument, 8 to energize the corresponding electromagnet 17 or 18 and drive a motor 29 in one or other direction. The motor controls the movable contact 35 of a resistance 41 which is connected in series with the master repeater and the distant instruments 44, 45. When movement of the member 1 occurs, the motor 29 varies the current in the indicating circuit to displace the pointers of the repeaters 8, 44, 45 until contact is broken between the master repeater and the primary member. Projections 38, 39 on the contact 35 are respectively adapted to open the pairs of contacts 47, 48 and 49, 50 in the motor control circuits in order to prevent the contact 35 from leaving the resistance when moved to either extreme position. Any number of distant repeaters may be connected in the indicating circuit and variations of line resistance, due, say to temperature, may occur without affecting the accuracy of the indications. In a modified arrangement, the contacts 3, 4, 5 are adapted to control directly a motor having a split-field winding, and in a further modification the contacts control electromagnets which operate the clutch of a continuously rotated motor. The resistance 41 may be connected directly across the supply, the indicating circuit then being connected between one end of the resistance and the movable contact 35. In a further modification adapted for an alternating current supply, the resistance may be replaced by a variable choke. A uniform scale law of the movements of the pointer 6 corresponding to an irregular scale law of the member 1 may be obtained by arranging the pointer and member on different axes.
