Title: Carburetor
IPC: F02M3/05
Filed: 1938-10-12
Abstract: 521,194. Spray carburetters. TRIGGS, W. W. (Leibing Automotive Devices, Inc.). Oct. 12, 1938, No. 29520. [Class 7 (iii)] The supply of idling fuel to a carburetter is completely cut off if the suction exceeds that normally present during idling, and slowrunning periods such as may occur during overrunning an engine when a vehicle, descends a slope. In the construction shown in Fig. 1 a throttle valve (arranged as in Fig. 2) comprising two plates pivoted on parallel axes controls the mixture passage and the plates at their meeting edges are cut away at 24 to surround closely an idling nozzle 29<1> and are formed opposite a transition nozzle 28<1> as a closed cup 25. Projecting into an orifice at 62 is a nozzle x through which the pressure in the inlet pipe is conveyed to a diaphragm 67 connected to a valve 55, 73 for regulating the fuel admission from a duct 54. In operation, during idling, the nozzle 29 is subjected to the suction below the. throttle valves and to the injector action of air flowing past the nozzle, the fuel being emulsified by air drawn through the transition nozzle 28; slight opening of the throttles checks the flow of aerating air and brings the nozzle 28<1> into use to supply fuel. During Overrunning of the engine, the fuel supply to the idling and transition nozzles is cut off automatically by a movement of the diaphragm 67 which responds to the rapid pressure, changes adjacent the throttle valve. In the construction shown in Fig. 3, the duct 76, which is the equivalent of the nozzle x shown in Fig. 1, is connected to the inlet passage during closed throttle conditions. through a passage 75 formed between the plates, of the valve. Fig. 5 shows a< >construction embodying a butterfly valve 86 the rim of which is cut away, to leave a sharp edge opposite the suction passage 102. Fuel discharged through the passages 89 and 91 adjacent the edge of the throttle valve is. controlled by a valve 99 carried by a diaphragm subject to the pressure transmitted through the pipe connection 101.

Filed: 1957-09-20
Abstract: <PICT:0810187/III/1> <PICT:0810187/III/2> <PICT:0810187/III/3> A crystallizer comprising a container 1 (Fig. 1), through which the crystallizing solution flows downwardly and in which cylindrical cooling elements 4 are suspended, is divided by plates having openings through which the cooling elements pass, into a plurality of superposed compartments 15, 16, 17, 18 and 19, and has a bottom discharge arranged to open and close intermittently.  Each cooling element 4 has a conical bottom 20 (Fig. 3), and liquid coolant is passed down a dip pipe 21 (Fig. 2), and flows upwardly in the element.  The elements 4 are supported by a resiliently mounted header having an anvil block 35 which is struck by a pneumatic percussion hammer 37 to remove crystals adhering to the elements. The dividing plates are metal cones 56 (Fig. 3), with openings surrounding the cooling elements 4 with clearances 59, and have central openings 58 below which are baffle plates 60.  Flat dividing plates may also be used. Crystals and mother liquor are discharged to a centrifuge 13 (Fig. 1), through a valve 11, periodically opened by a pneumatic cylinder 14, which causes the column of liquid in the container 1 to move downwards and turbulence is produced when the liquid flows through openings 58 and 59.  The edges of openings 58 and 59 may be covered with rubber rings.  Air bubbles may be passed through the cooling liquid to disperse boundary layers on the inside walls of the cooling elements.

Title: Process for the production of hard carbides, especially titanium carbide free from graphite
IPC: C01B31/30
Filed: 1936-11-02
Abstract: Crude titanium and like hard carbides are freed from graphite by heating the carbide to a temperature below its melting point, together with a metal adapted to react with graphite at a temperature below the melting point of the hard carbide, to form a carbide which is readily composable by acids, and decomposing the carbide thus formed by treating the carbide mixture with an acid. Suitable metals are iron and manganese.  According to examples, titanium carbide containing free carbon is heated with manganese powder at 850 or 900 DEG  C. in an atmosphere of hydrogen, the reaction product being stirred with dilute sulphuric acid.

[Class 140] [Also in Groups IX and XIII] In apparatus for treating yarns with liquid such as water, dye, or size and subsequently drying them wherein a number of yarns simultaneously pass over a furnishing roller 7 supplied with liquid from a trough 11, then through a comb or reed 20, a drying chamber 24, and another comb or reed 28 before being wound up, guide means 19 is provided between the furnishing roller 7 and the reed 20 which separates the yarns into a number of rows situated at different heights, the yarns being maintained apart while passing through the drying chamber and until dry. The guide means consists of positively rotated rods or rollers 19, and either the rods 19 or the reed 20 may be laterally reciprocated. The yarns are drawn from a pair of spaced creels 1, through a reed or comb 3, over a raised guide roller 4, through an adjustable reed 10, around a driven roller 6 mounted on pivoted arms 9, and between a pressure roller 8 and the furnishing roller 7. The trough 11 is supported by four slidable pins 12, 14 engaging corner lugs 16, so that it may be tilted or completely removed for cleaning. After the drying chamber 24 the yarns pass through an adjustable tension device 29, 30, 31 around a roller 33 and are wound up on a roller 34. One, two, or more yarns are wound separately on bobbins placed upon driven spindles 36, such bobbins when full being placed upon pegs 43. When a yarn breaks, the machine is stopped and yarn from a bobbin 43 used for piecing to the broken ends. The joined yarn is returned to the drying chamber through a slot running the whole length of the top of the chamber, guide horns 27 being provided. A lease reed 45 may be provided in front of roller 30 so that an end-and-end lease may be taken. The yarns are measured before and after the wetting &c. treatment and drying, so that the amount of stretch can be estimated.

The stopper is provided with metal and 'rubber washers 11, 12 which are compressed by a flange 10 on the stopper when the latter is screwed into place. Gas vent openings 14 in the stopper are covered by a rubber tube 15 and communicate with the hollow interior 13 of the stopper which may be divided by a metal strip 18 having a curved or bent lower end 19 to deflect to one side liquid passing into the stopper. Alternatively the lower end of the strip 18 may be provided with a hinged flap or other one-way valve so that liquid passing up one side of the strip 18 returns down the other side and is returned to the accumulator without reaching the chamber 9. The chamber 9 is closed by a rubber cap 17 in the form shown in Fig. 2. In Fig. 1 the chamber 9 is closed by a rubber or other pad 16 carried by the lid 2 of the accumulator container. The lid is hinged at 3 and carries a cable 5 which engages the accumulator terminals when the lid is closed.
