Title: Purification of elementary boron
IPC: C01B35/02
Filed: 1958-11-24
Abstract: <PICT:0841980/III/1> At least the inner surface of a hollow body of amorphous and/or crystalline boron is fused by radiant heat in a vacuum or inert atmosphere.  The resulting fused boron may have an increased purity of more than 99%.  The inner surface may be maintained at a temperature of 2000-2300 DEG C.  Heat may be radiated from a resistance element situated within the hollow body.  A tungsten element may be employed in a vacuum and a carbon element in an inert gas, e.g. helium, at a pressure of 1-10 c.m. of mercury. The boron body may be formed by compressing finely divided boron at a pressure of 20,000 p.s.i.  The body may be partially or completely surrounded by a spaced shield of boron, which may be prepared by moulding a stiff aqueous boron paste, drying at a temperature of 60 DEG C. for several days, and baking at a temperature of 1000 DEG C. in a vacuum for 1-2 hrs.  As shown, a hollow boron body is made up from a base disc 34 and a plurality of superimposed rings 32 and is surmounted by a boron disc 60 through which passes a resistance heating element 50 connected to water cooled lead pipes 52 and 54. The hollow body is supported on boron blocks 38 within a boron shield 40 consisting of a boron cylinder with an outer casing 42 of steel or copper.  The shield 40 is in turn supported on boron blocks 46 within a vacuum chamber comprising a base plate 12 and a bell jar 14 of glass or steel.  The chamber is evacuated through pipe 16 and liquid aircooled trap 20, while an inert gas is admitted to the chamber through pipe 80.  The body may have an internal diameter of 2 inches and an external diameter of 4 inches, and radiant heat may be supplied at a rate of 5-10 KW for 2 hrs.

Title: Improvements in or relating to threshing machines
IPC: A01F12/30
Filed: 1946-12-23
Abstract: 619,735. Threshing-machines. LENEHAN, P. Dec. 23, 1946, No. 37698. [Class 58] In a threshing-machine a screen 5 and chute 6 hinged at 10 are suspended beneath the jog shoe 2 and the delivery end of the shakers 1 by a hinge 9 and bars 12, 13 with the screen inclined downwards away from the delivery end and outward of the machine and the chute inclined downwards from the outer end of the screen and inwards into the machine and terminating at its free end above the riddle 3. The chute 6 may taper towards its free end and may be made in two or more separable sections one of which may move into the machine and allow the screen 5 to hang vertically when not in use. The screen may be of square form and extend the full width of the machine and consist of wires or laths parallel to the direction of movement of the straw.

Abstract: 952,040. Quenching gaseous reaction products. FOSTER WHEELER Ltd. Oct. 5, 1962 [Oct. 6, 1961], No. 37829/62. Heading B1X. [Also in Division F4] A reactor for effecting gaseous reactions comprises reaction tubes 14, through which the reacting gases are passed from an inlet manifold 16 to an outlet manifold 24, passing through a furnace chamber 12 having refractory lined walls 18 heated by burners 20, the hot reaction gases being quenched at the downstream ends of the tubes 14 by evaporation of sprays of cooling fluid, e.g. water, ejected into chambers 30 mounted within the tubes, and thermally insulated therefrom by annular gas spaces 32. The hot gases enter the chamber 30 through a perforated cap 58 which supports a catalyst 56, and the outlet conduit 22 is of sufficient diameter to give a low gas velocity, and hence a low heat transfer coefficient between the gases and the conduit wall, to avoid overheating in the event of a quench spray failure. The shell 28 of the chamber 30 is of a heat-resistant sheet material thin enough to deform under thermal stress, and has staggered baffles 54 which prevent fluid from the spray nozzle 42 from reaching the tube wall 14 or the catalyst 56.

Title: Piezoelectric transducer
Inventor: CADY WALTER GUYTON
IPC: H04R17/00
Filed: 1967-08-17
Abstract: 1,203,794. Piezoelectric elements. NORTH AMERICAN ROCKWELL CORP. 17 Aug., 1967 [17 Aug., 1966], No. 38021/67. Heading H1E. A transducer comprises a piezoelectric crystal having its electrical polarization along two orthogonal axes each determined solely by shearing forces parallel to one or other of these axes. The drawings show a crystal in the form of an elongated right parallelopipedon having pairs of electrodes on opposed pairs of longitudinal faces. These pairs of faces lie respectively in the XZ and YZ planes of the crystal and flexure in either one of these planes gives rise to a voltage across one pair of electrodes (parallel or normal to the flexure plane) but not across the other. The stress and polarization are connected by the equation Pm=e mh S h  where e mh  is one of the eighteen piezoelectric tensor stress coefficients, m = 1, 2, 3 indicating the axis of polarization and h = 1, 2 ... 6 the type of strain. The coefficient e may be written as a 3 x 6 matrix but since polarizations and shearing strains in the X and Y directions are considered, the 2 x 2 submatrix for which m = 1, 2 and h = 4, 5 alone is relevant. The mutual decoupling of the two flexure modes is possible when both coefficients along one diagonal of this matrix are zero, i.e. either e 14  = e 25  = 0 or e 15  = e 24  = 0. Of the twenty classes of piezoelectric substances, fourteen (a list is given) have this property and nine of these have non- zero tensor coefficients of equal magnitude. Substances falling within these nine classes are ammonium phosphate, potassium phosphate, quartz tourmaline and barium titanate. To obtain the necessary properties, it may be necessary to use oriented cuts and to consider the tensor coefficients relative to the rotated axes X<SP>1</SP>, Y<SP>1</SP>, Z<SP>1</SP>. Compressional and extensional strains are considered and it is stated that the effects of these strains are self cancelling. The invention may be applied to polarized polycrystalline ferroelectrics (e.g. barium titanate).

Title: Improvements in the destructive hydrogenation of brown coal and other oxygen-containing low-grade fuels
IPC: C10G1/06
Filed: 1928-12-31
Abstract: 330,222. Strong, H. W., and Imperial Chemical Industries, Ltd. Dec. 31, 1928. Hydrogenation, destruction.-In the destructive hydrogenation of brown coal, the comminuted material is dehydrated without oxidation by heating it at atmospheric pressure in the presence of an non-oxidizing gas and is then formed with a suitable oil into a paste which is submitted to destructive hydrogenation. The material may be mixed prior to the heat treatment with oil or tar which then forms the vehicle for the subsequent treatment. The coal may be heated in two stages, first to a relatively low temperature e.g. 150‹ C. to dry it, and then to a higher temperature e.g. 250‹ C. to eliminate combined oxygen. The heat requirements of the process may be obtained by heat exchange with the products of the destructive hydrogenation. The gases used may be hot flue gases, carbon dioxide, nitrogen or superheated steam. Powdered brown coal is heated in a stream of nitrogen to 250-300‹ C. in an inclined rotary drier. The treated coal with dust recovered from the gas by means of a cyclone is mixed with an oil boiling above 300‹ C. and the mixture is heated with hydrogen to 435‹ C. at 200 atmospheres in presence of a catalyst. Powdered brown coal is mixed with an equal weight of tar and heated to 260-300‹ C. in presence of nitrogen or steam for about an hour, most of the moisture being carried away by the gases. The product is then destructively hydrogenated. Specifications 301,946 , and 320,918 are referred to.

[Classes 65 (i) and 65 (ii).] A spring closing and holding device for doors opening against a wall at right-angles to the doorway comprises a bar 2, Fig. 2, pivoted at one end by a spring hinge 3 to the wall and carrying a roller at the other end which abuts against a stop 8 on the door when the latter is closed ; this stop yields to force, allowing the door to be opened against the pressure of the spring hinge, the end of the bar 2 running along a plate 7 on the door. The stop 8 is formed on a plate 5, Fig. 4, pivoted at 6 to the plate 7, and the free end of the plate 5 bears against a leaf spring 10, which provides the necessary resistance to yielding of the stop.

The device is also applicable to swing doors, in which case it may be duplicated on the other side of the door, and to revolving doors. Since the device tends to force the door away from its hinges, the door may be tied back to the door-post, particularly when doubleaction hinges are used, by a spring or by a tie rod pivoted to the door-post and having pin-andslot connection with the top of the door.
