Patent GB-981674-A (GB)
Title: Organo-substituted-amino diboron halides and their production
Inventor: AYRES BRIAN JOHN
IPC: C07F5/02
Filed: 1962-06-15
Abstract: The invention comprises diboron compounds of the formula B2XmY4-m, where X is an organo-substituted amino group, Y is a chlorine or bromine atom and m is 2 or 3.  X may be dimethyl amino, or other dialkylamino groups of up to 6 carbons, or amino substituted by cycloalkyl (e.g. cyclohexyl) or aromtaic (e.g. phenyl or benzyl). The tris (substituted-amino) diboron monohalides and bis (substituted-amino) diboron dihalides may be made by reacting a tetrakis-(N-organo-substituted-amino) diboron with an addition complex of a primary, secondary or tertiary amine with a boron trihalide. The preferred complexes are the adducts of the alkylamines or aromatic heterocyclic amines with boron trichloride or tribromide. The reaction temperature may be between room temperature and 200 DEG C., preferably between 90 DEG  and 160 DEG  C.  Alternatively a tetrakis (organo-substituted amino) diboron may be reacted with a hydrogen halide in the absence of water, preferably at temperatures between - 100 DEG  C. and + 30 DEG  C.  Tris (substituted amino) diboron monohalides can be made by reacting a bis (substituted-amino) diboron dihalide with a tetrakis-(substituted amino) diboron at temperatures between 0 DEG  and 200 DEG  C.  Compounds of the formula B2X2Y2 react with at least 2 molar proportions of hydrogen halides in the absence of water to form adducts believed to be bis (organo-substituted-amino) diboron tetrahalides, e.g. bis (dimethylamino) diboron tetrachloride <FORM:0981674/C2/1>  The reaction takes place above - 20 DEG , 10-30 DEG  C. being suitable. Examples describe the preparation of bis-(dimethylamino) diboron dichloride, tris (dimethylamino) diboron monochloride, and bis (dimethylamino) diboron tetrachloride by various methods.

Title: Improvements in and connected with furnaces adapted to burn various kinds of fuel
IPC: F23K3/10
Filed: 1921-09-02
Abstract: 182,034. Petersen, K. Sept. 2, 1921. Fire-bars and grates; ash-pits.-A furnace grate with a mechanical underfeed stoker is arranged so that the grate elements are adjustable to different inclinations from the stoker trough to the ash discharge side of the grate, to suit various grades of fuel. Figs. 2 and 3 show applications of the grate to a flue-boiler and a water-tube boiler respectively. The grate elements 17 are arranged transversely of the grate and are supported at their inner ends by the edges 19 of the trough 18, and are adapted to turn about the edges 19. The outer ends of the grate elements are supported by a plate 21 engaging rails 31 on the flue bottom, whereby the inclination of the grate may be varied. The lefthand half of Fig. 2 shows the grate in a position for burning highly volatile fuel, while the righthand half shows the grate in a more inclined position for less volatile fuel. Partitions 25 divide the grate elements 17 into longitudinal passages 26, 27, which have bars 23 on their upper sides. The spaces 24 between the bars 23 are arranged at such an angle that air or steam passing through them tends to move ash towards the troughs 1 at the sides of the grate. Plates 29 resting on flanges 30 at the bottom of the passages 26 regulate the quantity of air passing to different zones of the fire. Steam or water may be passed through the outer zones to disintegrate clinker formed on the bars. The ashconveyers may be either shafts 2 with screwblades 3 of increasing pitch and radius, as shown, or continuous helices of increasing pitch, so that equal amounts of ash are removed from all parts of the grate. The angle of the screw-blades 3 may be varied, while the blades are omitted in the tube 6, so that the clinker and ash become tightly packed, forming a seal to prevent air or gases from entering into or escaping from the furnace by the outlet 7. Water for quenching the ashes is supplied through the hollow shaft 2, or by other means, to the trough 1. The shafts 2 are driven through cranks and ratchet-gearing from the stoker driving-shaft. Modifications are described in which the grate surfaces turn about axes at the sides of the furnaces, and may be composed of bars lengthways of the grate.

Infusers. - A coffee pot for making Turkish coffee and of the kind in which the filter is placed between two receptacles in the lower of which water is caused to boil and rise through the filter into the first receptacle containing the ground coffee, the coffee solution then returning to the lower receptacle through the filter when the lower receptacle is removed from the source of heat, is characterized by a removable filter which is fitted to the lower receptacle by a clamping device which serves to seal the joint between the two receptacles, the lower receptacle serving as a power device when the filter is removed. In Fig. 1 the filter members 3, 4 are mounted upon a rod 10 which is secured to the base 5 of the upper container 8 by a detachable cotter 11 engaging the tube 6 and the rod. After water has been added to the lower container 1 the rod 10 is screwed into the base 12 until the elastic ring 9 forms a tight joint between the flange 7 and the ledge 2. Ground coffee is then placed upon the filter and the device placed upon a source of heat. Steam generated in the container 1 forces water up the tube 6 and through the filter to mix with the coffee. The mixture is stirred, the source of heat removed, and the coffee solution allowed to filter into the lower receptacles This operation may be repeated. A detachable filter adapted to be fitted to a single receptacle may be used, as in Fig. 4. The tube 18 through the lower end 19 of which the hot water is forced, is provided with a base 17 with resilient sealing means 26 to engage the walls of the container 15. The filter 22 has an extension 24 in which is a screwed rod 25 to force the flange 21 into sealing contact with the resilient member 26. The vessel may be edectrically heated through a resistance coil 16. A modification is described employing two receptacles which may be dismounted and fitted one within the other. Modified constructional details for effecting a sealed joint by means of the elastic ring or material are also described.

Title: Acoustic-vibration generator
IPC: G10K9/04
Filed: 1959-07-08
Abstract: 926,519. Acoustic vibration generators. J. V. BONJOUCOS, and F. V. HUNT. July 8, 1959 [July 8, 1958], No. 23439/59. Class 13. An acoustic-vibration generator, Figs. 1, 4, comprises a fluid-pressure-actuated valving member 1 in a chamber 12 formed in a housing, inlet passages 8, 8<SP>1</SP> leading to ports 3 at opposite ends of the chamber 12 for feeding fluid into the ports 3, a discharge orifice 13, 14 leading from the chamber 12 for discharging fluid passing through the ports 3 to the chamber, and guiding elements 4 for guiding the valving member 1 into and out of at least one of the ports 3. The arrangement is such that at the ports 3 pressure variations of fluid on opposite faces of the valving member 1 produce selfexcited oscillations by which the valving member 1 reciprocates into and out of at least one of the ports 3. The chamber 12, valving member 1 and ports 3 are cylindrical, see Fig. 2. The fluid fills a load-coupling horn 20 and a cavity 22 bounded by a hemispherical window 21. The guiding elements 4 have notches 23 and also rounded edges 17, Fig. 5. The valving member 1 is spun by directing the flow at inlet passages 8, 8<SP>1</SP> to one side of each cavity 2, 2<SP>1</SP> and towards the guiding elements 4. The fluid rotates in the cavities and drags the valving member with it while providing a fluid film between the guiding elements 4 and the rims 5, thereby reducing frictional wear. Many modifications are shown and described. For example, Figs. 15, 16 show four runners 404 which constitute the guiding elements and co-operate with a tapered valving member 102. In another arrangement supplemental fluid is fed through guiding elements 405, Fig. 20, and provides centring of the valving member 101. A central strut 33, Fig. 21, runs through and supports valving member 104, the strut being supported by spiders 33<SP>1</SP> fixed within the ports. The bearing shaft 35, Fig. 23, is sealed by 0-rings 39 and is connected to an external load or control device 40. A " single ended " generator, Fig. 24, has at its lower end a land 41 which rides along rim 5 and maintains the lower orifice closed. Specification 845,299 is referred to.
