Title: Improved method for the production of fuel briquettes with adjustable content in volatile substances
IPC: C10B31/02
Filed: 1936-07-11
Abstract: 475,915. Charging retorts. SOC. DE CARBONISATION DE MOLIERES - SURCEZE. July 11, 1936, No. 19316. Convention date, July 12, 1935. [Classes 51 (ii) and 55 (i)] Externally heated vertical retorts for carbonizing fuel agglomerates are charged, after each complete or partial extraction through the bottom of the retort, by means of a series of horizontal and vertical movements of the charging device to build up progressively ascending levels so as to prevent the crude agglomerates falling such a distance as would cause damage. A retort 1 has charging orifices 2, 3, through which passes a shoot 5 supported by a travelling bridge 6 and lifted and lowered while retaining its optimum inclination. Anthracite agglomerates required to contain at least 3 per cent of volatiles are carbonized in a single operation, the retort then being entirely emptied. A two stage carbonization as described in Specification 422,943 is effected for agglomerates with a smaller volatile content.

Title: A method of and apparatus for the production of compressed boards from fibre-containing materials
IPC: B27N3/14
Filed: 1957-06-19
Abstract: <PICT:0849838/IV(a)/1> In the production of chip - board or other fibrous pressed boards, chips, &c., previously coated with glue, fall from a conveyer 1 past a switch-bar 2 to regulate the degree of filling of a storage hopper 3 at the lower part of which is roll 4 with pins 4a supplying a conveyer 8 which carries the chips etc. upwardly past a gauge-bar 9 to a roll 10 with curved pins 10a which presses lightly against, and levels the stream of chips and throws back any excess.  The chips then fall through a vertical shaft 13 within which are series of comb-like screeningbars 14 set at different angles.  Small particles tend to fall between the bars, and larger pieces are directed to the opposite side of the shaft, one side of which has air-inlet openings 15.  After falling through separator aprons 25 secured to travelling chains &c. 24, the chips fall on to a press plate 16 on a travelling conveyer 19. The finer particles may be on the underside of the layer on the press plate, or if the direction of movement of the conveyer is reversed at the end of a traverse of the plate and a second layer is deposited, there are finer particles on both the surfaces and coarser particles in the middle.  Alternatively, there may be two distributing appliances depositing chips in succession on travelling press plates. Successive plates may overlap slightly on the conveyer which may be in three sections.  The edges of the layers of the material thus formed may be shaped by vibrating plates.

Title: Improvements in or relating to methods of coating electrodes of electron discharge tubes
IPC: H01J29/02
Filed: 1946-06-28
Abstract: 613,727. Electrode materials and processing. RAULAND CORPORATION, and SZEGHO, C. S. June 28, 1946, No. 19355. [Class 39 (i)] An electrode of an electron discharge device is formed of a metal of low-melting point which, for the purpose of reducing anamalous field emission, is coated by evaporating on at least a portion of its surface a metal of high work function which either during or before the coating process, without further treatment of the metal between the heating and coating processes is heated in vacuum to a temperature exceeding approximately 1900‹ K. Metals of low and high melting points have melting points below and above 1900‹ K. respectively. Preferably the metal of high work function is also of high melting point. In one example the electrodes of a high voltage cathode-ray tube are formed of an easily malleable metal such as nickel or iron. A deposit of molybdenum is then provided on the electrode by heating in a vacuum, for example, of the order of 10<-5‹> mms. of mercury, molybdenum until it evaporates at a temperature above 1900‹ K. Instead of molybdenum, metals such as platinum tantalum or tungsten may be used. The nickel electrode may be coated in a vacuum tube separate from that in which it is finally housed, since it is stated that the exposing of the treated electrode to air does not spoil the result. The coating of the electrode may be accomplished during the first vacuum degassing. The coating operation can also be performed in the finished tube envelope. For example, a platinum wire may be fastened to a tungsten cathode and evaporated on to the grid diaphragm by heating the cathode. Similar results may be obtained by heating a low-melting point metal, for example, silver, to approximately 2000‹ K. and depositing it on the electrode. In the case of silver, it may be heated at 1900‹ K in a vessel so that evaporation does not take place, and then subsequently evaporated at a temperature lower than 1900‹ K so as to form a coating on the electrode, which itself may be silver. As shown, the cathode 20 of tungsten has a small cup 21 containing the metal to be heated. This is done by passing a current through the cathode. The metal then evaporates and deposits on the control electrode 23.

Title: Tractor and plough combinations
IPC: A01B63/22
Filed: 1963-05-16
Abstract: 1,026,526. Agricultural implements. BENNO GASSNER, and JOHANN GASSNER. May 16, 1963 [May 18, 1962 (2); Nov. 13, 1962; Nov. 23, 1962], No. 19413/63. Heading A1B. A plough connected to a tractor by means of upper and lower links comprises a gauge wheel which determines the depth of cut of the plough and which is mounted on a pivoted arm and is connected by means of a cable to a lever system which on lifting of the gauge wheel introduces a force into the top or bottom link and cancels such force when the gauge wheel drops. As shown in Fig. 5 a cable 68 is attached to a lever system 88 which raises or lowers the upper link 42. When the implement is attached to a tractor having a hydraulic lift system the linkage causes movement of the upper link which results in movement of the links by the hydraulic mechanism. As shown in Fig. 8 the upward movement of the gauge which is transmitted hydraulically by a cylinder 140 to a cylinder 144 which produces a tension in a linkage 142 which produces a pressure in the upper link thus causing the hydraulic mechanism to raise the plough.

IPC: B62M11/14
Filed: 1963-05-17
Abstract: 1,004,766. Variable-ratio gears; ratchet clutches. RALEIGH INDUSTRIES Ltd. April 13, 1964 [May 17, 1963], No. 19619/63. Headings F2C and F2D. A change-speed gear hub comprises a stationary sun 12, and a planet carrier 13 and a ring gear 15 which are selectively clutchable to a driver 17, the planet carrier being connected to a hub shell 20 by a unidirectional clutch 37 and a ratchet mechanism 19 arranged in series, and the ring gear being axially slidable so as to be engageable with the input side of the ratchet mechanism 19. Drive is thus always transmitted through the ratchet mechanism. An axially slidable selector sleeve 18 is splined to the driver and in the left-hand position to which it is biased by a spring 46 dogs 26 on the sleeve abut against planet pins 27 and the ring gear 15 is biased to its left-hand position by a spring 29 so that axial dogs 21 on the ring gear engage peripheral dogs 30 on a pawl drive plate 31. Pawls 33 are pivotally mounted between plates 31, 32 and co-operate with ratchet teeth 35 fast with the hub shell 20. In the left-hand position of the selector sleeve 18 the planet carrier overdrives the ring gear which transmits drive to the hub shell through the clutch dogs 21, 38 and the ratchet mechanism 19, the clutch 37 over-running. Direct drive is obtained by sliding sleeve 18 to the right so that the dogs 26 engage dogs 23 on the ring gear, and low gear is obtained by sliding the sleeve further to the right so that extensions 28 of the selector sleeve dogs 26 abut the rear face of a flange 22 of the ring gear and shift the ring gear to the right to disengage the clutch dogs 21, 38. The ring gear now drives the planet carrier at reduced ratio and the planet carrier drives the hub shell through the unidirectional clutch 37 and the ratchet mechanism 19. The unidirectional clutch 37 is of the wedging roller type and has a roller spacer 43 between the rollers and a drag spring 44 engaging the spacer to cause it to lag relatively to the planet carrier and thus to give immediate drive through the clutch 37 when desired.
