Title: Method of rendering a powder free flowing
IPC: C09K11/02
Filed: 1938-02-08
Abstract: 511,038. Rendering chemicals free flowing; coating surfaces. PULESTON, R., and HENDERSON, S. T. Feb. 8, 1938, No. 3904. [Classes 1 (iii) and 95] [Also in Group XL] Powders such as the sulphides or silicates and tungstates of zinc or zinc and cadmium used in the manufacture of fluorescent screens are made free flowing by coating the grains with silica. A warm dilute solution of pure potassium silicate is added to the powder and thoroughly stirred, then acidified with acetic acid and made alkaline with ammonia. Silica is deposited as a thin layer on the grains which are fiiltered, washed and dried. The amount of silica is usually about 2-4 per cent. of the weight of powder treated, but up to 10 per cent. is permissible without excessive deterioration of the fluorescent properties. The treatment may take place at any stage in the manufacture of the powder. Specifications 313,652, [Class 1 (iii)], and 449,392 are referred to.

Abstract: 252,078. Gramophone Co., Ltd., and Mittell, B. E. G. Feb. 18, 1925. Repeating and amplifying systems; systems for transmitting music &c.-In a method of recording sound by electrical means upon a plurality of record surfaces simultaneously, provision is made for varying the characteristics of each record by varying the electric circuits to the recorders. A monitoring loud speaker may be inserted in the circuit of any of the recorders. In one arrangement, electric oscillations produced by sound waves on a microphone a after transformation at b, amplification at c and transformation at s are supplied to separate circuits to actuate electromagnetic recorders h, i, and the second circuit of the second transformer s contains an impedance f acting as a potentiometer, points on which are connected to contact studs by other impedances l<1>, l<2>, l<3>, m<1>. m<2>, m<3> such that the total impedances on the circuit through any contact stud is the same and equal to that of the secondary of the transformers. The central point g of the impedance f is connected to each recorder, and by connecting the arms j, k to different contacts the recorders are actuated to produce records having different characteristics. In a modified arrangement the secondary of the sound transformer is replaced by two coils which are connected directly, or through impedance circuits and contact studs such as described, with the recorders; or the currents in the two secondary coils may be amplified and passed through further transformers before actuating the recorders. The current in the recorder may also be varied by taking tappings from a choke coil in the output circuit of the amplifier and connecting any of these to the recorder or to the input circuit of the succeeding amplifier if an additional one is employed.

A rotary-piston I.C. engine of the roller vane type comprises two coaxial stators 2a, 2b (Fig. I, not shown) containing eccentric cylindrical rotary-pistons or rotors 11a, 11b coupled to one another by a shaft 13 and separated by a fixed partition 4 having a transfer port 22, the engine thereby including two units in one of which working fluid is compressed whilst in the other products of combustion are expanded. Each rotor has a plurality of radial slots 16a, 17a, or 16b, 17b (Figs. 2, 3, not shown) carrying roller vanes 18a, 19a, or 18b 19b, which engage with a fixed lining 7a, or 7b, in the associated stator, the slots in the two rotors being angularly displaced from one another (Fig. 8, not shown). The leading side of each slot in rotor lie is provided with a recess, adjacent partition 4, having a side 16a-1, or 17a-1, tangential to the semi-cylindrical base of the slot. Similar recesses are provided on the trailing sides of the slots in the other rotor. Each roller vane comprises two hollow portions or halves 18a-1, 18a-2 (Fig. 4, not shown) which slidingly engage with one another and are pressed in opposite directions into contact with partition 4 and the end wall of the associated stator by the pressure of hot air or other gases trapped within the vane. In operation, fuel-air mixture is drawn through a port 21 in stator 2a and compressed by rotor 11 a before it is transferred to stator 2b when adjacent slots in the rotors and the recesses associated therewith are in register with port 22. The compressed mixture in stator 2b is ignited by ignition means, e.g. a spark plug, lodged in one or more apertures 23 and the combustion products are ejected through a port 24. Each slot in rotor 11a may also contain a slidable block or shoe 103, or 104 (Figs. 9 to 12, not shown) situated on the leading side of the roller vane to prevent compressed mixture being returned in the slot from port 22 to port 21. A bearing 8a for rotor 11a is lubricated by oil in the fuel-air mixture, the oil being subsequently circulated through a pipe 30, a bearing 8b for a power-output shaft 10, and a pipe 31 connected to port 21. Coolant is circulated through spaces 3a, 3b in the stators and bores 15 in the rotors. The engine may be modified to use a gaseous fuel, in which case lubricating oil is sprayed into the working spaces defined by the rotors and stators.

Title: Improvements in or relating to the production of metal meshes
IPC: H01J9/14
Filed: 1937-02-17
Abstract: A mesh, particularly a metal mesh for use as an electrode in an electric discharge device is made in the following manner.  An existing mesh is laid on a supporting surface and carbon is deposited through it, for example from a gas flame, and the mesh then removed leaving a carbon mosaic on the surface.  Metal such as silver or aluminium or other material is then deposited by vaporization cathode sputtering or otherwise over the whole and the carbon and the material deposited thereon are washed away, leaving an adherent mesh of deposited material.  The mesh may be removed from the supporting surface, if necessary after thickening by electrodeposition, or when the support is of insulating material such as glass or mica the mesh may be retained thereon. After removal of the original carbon mosaic and before removal of the deposited mesh, carbon may be deposited in adherent form, for example by spraying from a suspension, so that, on removal of the mesh, an adherent carbon mosaic is left on the surface.  In performing the operations described, a mica sheet may be mounted over a metal block, preferably slightly curved, and the pattern mesh mounted over it by means of a stretching frame as described in Specification 479,024, [Group XXII].

Abstract: 783,517. Casting-processes. MANNESMANN AKT.-GES. Feb. 17, 1954 [May 7, 1953; Aug. 5, 1953], No. 4715/54. Class 83 (1). In a continuous-casting process, when the speed of descent of the casting is increased the rate of cooling along the whole length of the casting containing the liquid core is maintained constant or increased simultaneously with, but by an amount which is less than proportional to, the increase of speed of descent; or when the speed of descent of the casting is decreased the rate of cooling along the whole of the casting containing the liquid core is simultaneously decreased by an amount which is more than proportional to the decrease of speed of descent of the casting. The process is said to avoid porosity in the core of the casting. The operation may be carried out with constant cooling along said length with a constant or increasing speed of descent. Alternatively if both speed of descent and rate of cooling are varied, a lessthan proportional increase of the cooling rate takes place simultaneously with an increasing speed of descent, or an over-proportional decrease in cooling rate takes place simultaneously with a decreasing speed of descent. Shaking or vibrations may be produced by manually or mechanically driven beater or shaker devices, vibrators, sonic or ultrasonic appliances, &c.

Abstract: 221,732. Lobnitz & Co., Ltd., and Bedgood, H. O. Feb. 25, 1924. Drags. - A truck for drag-line excavators which is so built that its body is capable of movement about a pivotal centre below the back axle is arranged with the axle having bearing bushes near each wheel and a saddle bearing on both bushes and secured to depending plates on the body by a pivot pin located centrally below the axle. The excavator platform 1 is pivotally mounted as at 2 on the trucks (usually four in number) and limited in its movement by chains 5. The truck body comprises a top 4, a lower frame 7 carrying longitudinal channel girders 6, end plates 8, 9, strengthening plates 10, and a stiffening plate 11 which with the angle irons 11<a>, 11<b >supports the direct load of the excavator. The rear is supported on the axle 25 bv means of a saddle 23 which rests on half bushes 24 resting on axle bearings 26, 27, the bushes having checks 31. A pivot pin 20 passes through depending parts 21, 22 of the saddle and through plates 16, 17 secured to the frame 7 by angle brackets 18, 19. The plates 16, 17 are stiffened by channel stiffeners 14, 15 and are supported by angle brackets 12, 13. This arrangement allows relative movement of the body and back axle. The front axle 32 supports half bushes 34 and saddle brackets 33 provided with binding plates 38. The pin 20 and plate 38 prevent the body rising off either axle. The arrangement gives a three-point support for the truck body, namely, two bearings on the front axle and the central pivot at the back axle, and stresses are so distributed that there is no liability of the axles bending at the centre.
