Title: Improvements in process of and means for dehydrating colloid material
IPC: C10F5/04
Filed: 1933-02-15
Abstract: 411,602. Presses for separating liquids from solids. ROGGEN, M. VAN, Sprigmont, and ROBIN, L., 25A, Avenue Adolphe Buyl, Brussels, both in Belgium. Feb. 15, 1933, No. 4678. Convention date, Feb. 18, 1932. [Class 46.] In the dehydration by pressure of colloid material such as peat which is in contact with an endless band of absorbent material, the band is separated from the colloid material before it has become fully saturated, whereupon it is dried and again brought into contact under pressure with more colloid material. So long as the band is unsaturated, water may be expelled from the colloid material at a higher rate than the rate of absorption by the band yet without loss of material. The band may be of cotton, flax, hemp, jute, wool, cocoa-fibre or the like, and may be tanned to withstand rotting and charged with an electrolyte to promote coagulation of the colloid. The drying may be assisted by the use of a pulverulent material, e.g. dried peat. In one form a plant for carrying out the process has a belt 2 adapted to convey a thin layer of peat through a press 3, in which the peat is compressed between the belt 2 and a similar belt 7. The wet peat is fed from a hopper 4 which also subdivides the material. Powder-sprinkling devices 5, 6 are provided. On emerging from the press, belts 7 and 2 pass into contact with scrapers 8 and 9, so that the material is transferred to a belt 10 forming part of a similar press 16. The belts 2 and 7 then pass through drying chambers 12 and 13, and through cooling devices 22, 23. The belt 2 also passes through a bath 11 contain ing electrolyte. In another form the same pair of belts is used in both presses, each belt being twice dried in a full circuit.

Patent GB-252435-A (GB)
Title: Improvements in and relating to brake engines, for winding mechanism and the like
IPC: B66D5/26
Filed: 1925-02-21
Abstract: 252,435. Logan, H. H. Feb. 21, 1925. Brakes for winding-apparatus ; overwinding and overspeeding, preventing.-In a brake engine for applying the brakes to winding-gears of the type in which a weighted brake lever is released normally by hand and automatically in emergency to fall under the control of a dashpot, the opening in the dash-pot is varied by manual means during normal braking and by automatic means in emergency braking. In the present construction the weighted brake levers (not shown) are connected to the shaft 6 of a crosshead 3 and are allowed to fall by releasing the pressure in a cylinder 1 and thus lowering the crosshead. A second piston works in a dash-pot 7 during the movement. The hand controlling lever (not shown) operates the shaft 19 through the medium of the arm 20, Figs. 2 and 5. In the brake-applying direction the movement of the shaft 19 is transmitted through the slotted link 22, while in the reverse direction the slotted toggle link 32 transmits the movement. When this shaft turns in the brake-applying direction, the link 22 depresses the pivot 24 of the lever 25, thereby turning the lever about the point 30 and actuating links 26, 14 to rotate and thus open one valve 9 of the dash-pot 7 and also the main valve of the cylinder 1 bv means of the connecting rod 15. This allows a slow application of the brake. Should the hand controlling lever not be thrown right over to apply the brakes fully, the cross head continues to fall until it rotates the lever 25 about the pivot 24 sufficiently to re-close the valves, thus locking the crosshead with the brakes partly applied. On reversing the rotation of the shaft 19 the link 32 remains effective to restore the lever 25 so long as the toggle arms are in a straight line, but should the solenoid 37 be de-energized on overspeed or overwinding, the core 38 falls and the toggle is bent by the arm 45 to render the hand lever incapable of taking off the brake. The solenoid core also operates the valve 9 and a second bye-pass valve 60 which allows a quick application of the brake. The crosshead is restrained from further movement when the brakes are fully applied by the arm 62 which actuates a second valve 60<1>, Fig. 4, inside the by-pass valve 60 and puts the latter valve out of action.

Title: Improvements in or relating to internal-combustion turbines
IPC: F01D1/02
Filed: 1941-04-15
Abstract: 585,331. Gas turbines. GRIFFITH, A. A. April 15, 1841, No. 4923. [Class 110 (iii)] Gas turbine blades have hollow shroud rings into which cooling air is admitted. In the turbine shown, the inner blades 12, on the independent and oppositely rotating discs 11, form the air compressor and the outer blades 16 are those of the turbine. The turbine blades are secured upon rings forming the shrouding for the compressor blades and these rings are made of parts 14, 15 separated by an annular air space. The air spaces of the several rings form a continuous annular air channel. Air may be admitted to this channel from the compressor delivery and evacuated to atmosphere by a channel 20. Or, it may be left to escape into the compressor and turbine bladings. In the former case, blades may be provided in the annular channel to cause the air to do work. In the latter case, the leakage outlets direct the air suitably into the air and gas streams. Alternatively, a low pressure may be maintained in the annular channel and any gases leaking into it are withdrawn. Specification 583,330 is referred to.

Filed: 1939-02-15
Abstract: 525,159. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. (Carter, P. S.). Feb. 15, 1939, No. 5024. [Class 40 (v)] Relates to short-wave aerial and transmission line systems for transmission or reception, having a flat impedance-frequency characteristic over a wide range of frequencies. According to the invention, the system comprises a graduallyexpanding or conical aerial and a transmission line the transverse dimensions of which gradually expand and merge, without abrupt change, into those of the aerial. In Fig. 3, the diameters of the inner and outer conductors of the two co-axial transmission lines TL<SP>11</SP> are gradually increased towards their open ends, the ratio of the outer and inner diameters of the lines being maintained constant. The conical surfaces 1, 2 formed by the inner conductors are arranged to project beyond the conical surfaces 3, 4 formed by the outer conductors and the edges of the latter are flared. In a modification, Fig. 1 (not shown), the outer conductors are dispensed with, the two inner conductors then together forming a two-conductor transmission line. In a further modification (Fig. 2, not shown), the conductors of a single co-axial line are expanded, the inner one forming a cone and the outer one forming a flared-out mouth which may be continuous with a conducting surface, e.g. a wall or the ground, perpendicular to the axis of the inner cone.

Abstract: 525.165. Weighing-apparatus ; electric control systems. HADLEY, H. A. Feb. 16. 1939, No. 5060. [Class 143] [Also in Group XXXVIII] In a weighing scale of the beam type the oscillations of the beam are limited and checked by a coupling member moving up and down with the beam against the resistance in both directions of an operating means governed automatically by a control means. As shown, the movements of the scale beam 3 are restrained by resilient contact arms 20 which are situated between insulated contactor arms 34 suspended from the scale beam by members 27, 23. When the beam moves up or down under the influence of the load a circuit is completed through either the lower or upper contacts thereby causing a motor RM to rotate in one direction or the other and by moving a rack 12, raise or lower the contact arms 20 until the circuit through the contact arms 20, 34 is broken at the balancing point. Any undue shock imposed on the scale mechanism due to excessive load is taken up by the stop mechanism. Usual indicating mechanism within a dial casing is connected to the scale beam.
