Filed: 1917-09-12
Abstract: 110,160. Westinghouse Electric & Manufacturing Co., (Assignees of Schmidt, H. F.). Sept. 27, 1916, [Convention date]. Motor power plant.-A reversible marine turbine installation designed for a wide range of loads and speeds comprises a high-pressure section 3 and two low-pressure sections 4, 5 geared to a single propeller shaft 6 through reduction gearing 8, 36, 37, 9, the pinions 8, 36, 37 being preferably of different diameters, and the lowpressure-sections are adapted to receive motive fluid from different working stages of the high-pressure section. For full speed ahead, steam flows through the high-pressure stage 10 of section 3 and then divides into two streams, one of which flows through a pipe 20 and port 21 to the low-pressure section 4, while the other flows through the intermediate-pressure stage 11 and then through a pipe 22 and port 23 to the low-pressure section 5 where it flows in parallel through the two stages 17. The port 21 is so located'that it by-passes the first stages of section 4. For cruising speed, the valves in the connecting pipes are manipulated so that steam flows through the stages 10, 11, pipe 20, port 21<a>, and all the ahead stages of section 4. By manipulating the valves 24, 26, 27, other combinations are obtainable. The reversing elements 15, 28, 30 may be combined as follows. For maximum speed, the steam flows through the stage 15 and then divides into three streams, two of which flow in parallel through the stages 30, while the third flows through the stage 28. For low speed, the stages 30 are cut out; for intermediate speed, the stage 28 is cut out. For emergency use, high-pressure steam inlets 41, 42, 43, 44 are provided.

Title: Improvements in or relating to Apparatus for Mounting and Removing Pneumatic Tyres.
Inventor: BRAND JOHAN WESSEL
IPC: B60C25/04
Filed: 1917-09-13
Abstract: 118,887. Brand, J. W. Sept. 13, 1917. Tyres, elastic, and tyre covers, tools for removing and replacing.- A device for mounting or detaching a pneumatic tyre, adapted to operate on both edges of the tyre simultaneously, comprises a rod 14 having an eye 15 to engage the wheel hub 19 and fitted with a plate 7 which is hooked at 8, 9 and carries rollers 12, 13 and a rotary disk 10. In assembling a tyre, the edges are fitted to the rim at the top of the wheel, the outer bead being held by the small hooked lever 1. The eye 15 of the rod 14 is then passed over the hub and the hooks 8, 9 engaged with the rim flange. In this position, one or other of the rollers 12, 13 will engage the tyre bead, and the disk 10 will press against the tyre above the bead. The wheel is then rotated sharply in the direction of the arrow 25, Fig. 5, so that, when the end of the rod 14 strikes the ground, the continued movement of the wheel (due to its momentum) causes the device to force a further part of the tyre into the rim, this process being repeated until the complete tyre is assembled. To detach the tyre, the beads are raised at one part by means of the lever 1, and the rod 14 passed between the tyre and rim. The rod is then turned so that the eye 15 engages the wheel hub, Fig. 10, and the wheel rotated repeatedly, as in the detaching operation, the impact of the rod 14 on the ground causing the tyre to be forced out of the rim. For freeing a tyre bead which may have seized on to the rim, the tools are arranged as shown in Fig. 7, the rod 14 acting as a lever fulcrumed in one of a series of holes in the lever 1. To prevent abrasion of the wheel, the eye 15 and rod 14 may be fitted with leather, fibre, or like coverings.
Patent GB-131537-A (GB)
IPC: F01B17/04
Abstract: 131,537. Yarrow, H. E. Jan. 9, 1919. Motor power plant.-A four-cylinder marine engine driving two shafts is arranged to work as a single unit using triple or quadruple expansion, or as two independent sets of engines using double or single expansion. In the arrangement shown in Fig. 1, the two low-pressure cylinders LP<1>, LP<2> and the intermediate cylinder IP are the same size. The arrangements of pipes and valves are shown diagrammatically. With the valves so arranged, the engine works with triple expansion. The steam enters the passage A, passes the valve B to the high-pressure cylinder HP, and exhausts through the pipe 3, past the valve F, to the cylinder IP and then passes by branches 4, 7, 13 to the cylinders LP<1>1 LP<2>. When valve C is opened,. valve E moved to the right, valve F lowered, and valve H raised, the cylinders HP, LP<1> work as simple engines, the valve C being raised by the pressure, and the cylinders LP<2>, IP work compcund. In a modification, the system works triple expansion with four cylinders, or as two. sets with double expansion. In a further modification, the cylinders work with quadruple expansion or as two sets with double expansion. Starting in all the systems is facilitated by opening the valve C.

Dimethylformamide may be employed as reaction medium.ALSO:A herbicidal composition comprises a substituted nitraniline having the general formula:  <FORM:0946862/A5-A6/1> in which R is a hydrogen atom, a cyclohexyl group substituted by one or more alkyl groups having 1 to 5 carbon atoms, a cyclohexylmethyl group or a cyclohexylmethyl group substituted in the cyclohexane ring by one or more alkyl groups having 1 to 5 carbon atoms and n is 1 or 2 (see Division C2) together with a finely divided solid or inert liquid carrier.  The compositions are particularly useful in controlling the growth of crab grass. Solid carriers specified include talc, clay, pyrophyllite, silica and fuller's earth and organic solvents are stated to be employed for making liquid compositions.  Solid and liquid compositions may contain a surface active agent e.g. soft or hard sodium or potassium soaps, alkali metal salts of alkylated aromatic sulphonic acids e.g. sodium dodecylbenzene sulphonate or the corresponding amine salts e.g. the dibutylammonium salt, alkali metal salts of sulphonated fatty alcohols and the ethylene oxide condensation products of alkyl phenols, tall oil and high molecular weight mercaptans.

IPC: F23K3/00
Filed: 1926-05-26
Abstract: 281,098. Brand, J. J. C., and Laing, B. May 26, 1926. Feeding.-To facilitate the flow of powdered carbonaceous or other material from a receptacle through pipes, conduits or the like material is subjected in the receptacle to aerating or fluffing up by air or an inert gas so as to increase the normal inter-air space between the particles of material by approximately 30 per cent to 60 per cent after which the material is forced from the receptacle by fluid pressure applied from above. The method feeding may be applied to furnaces, stoves and the like or to conveying powdered coal from receptacles on shore to the bunkers of a ship. The Figure shows a portable form of fuel receptacle 1 arranged for feeding powdered fuel to a combustion chamber 12. A hand pump 2 supplies air to a reservoir 5 from which it is fed through valve-controlled pipes 6, 7 to the space above the fuel and into the mass of fuel respectively. The fuel and air mixture is delivered in a whirling stream produced by a helical plate 11 through a valve 10 to the burner 9 and thence to the combustion chamber where it meets secondary supplies of air from passages 13, 13a in the refractory curved wall 12a. The receptacle 1 is fitted with a removable cover 15 and a pressure gauge 16. If desired, the fuel may be fed continuously into the upper part of the receptacle by a screw conveyer. The pipe through which the fuel is fed to the burner may be provided with a carburettor described in Specification 279,767, [Class 75 (i), Burners &c.]. The powdered fuel which it is preferred to employ is that obtained by grinding the solid residue remaining after the distillation of carbonaceous material by the method described in Specification 276,407, [Class 65 (i), Coking &c.].

Turning wood-screws.-In a machine for turning wood-screws in which the lateral and the cutting feeds are given by cams 18, 30 mounted on a common spindle 19, the lateral-feed cam 18 is caused to hold the tool 8 in its outermost position while the cam 30 operates to turn the bar-slide 6 and thus feed the tool 8 for pointing the screw blank 5, rotated, and held by a chuck 4. The cam 18 then operates, through a lever 11 and an adjustable stop 14 which determines the rate of feed, to traverse and return the tool several times, while the cam 30, acting through a pin 29, spring-pressed pressure-relieving stop and adjustment 28, lever 22 carrying the cam 38, pin 39, and lever 9, simultaneously acts to feed the tool to the right depths and withdraw it at the right times. The spring-pressed pin 28 ensures that the pressure in the tool does not become excessive. The cam 38 and adjustable pin 39 give the screw its taper form.
