Title: Improvements in and relating to braking devices for motor vehicles
IPC: F01L13/00
Filed: 1952-11-17
Abstract: 716,095. Controlling vehicles. SOC. ANON. A. SAURER. Nov. 17, 1952 [Jan. 17, 1952], No. 28941/52. Class 79(5) [Also in Groups XXVII and XXXIV] In a braking device for motor vehicles comprising an exhaust brake and at least one service brake, the controlling members of the exhaust brake and of the service brake are both connected to a common control lever in such a manner that both brakes may be operated together and that at least the exhaust brake is capable of being operated alone. A lever 43 is provided on the steering column 42 of the vehicle so that when the lever is in position 1, illustrated in dotted lines, the lever 39 of the pressure regulating valve 21 allows no flow of compressed air from the reservoir 1 to the pressure cylinder 23 so that the lever 27 of the service brake 28 is kept in its inoperative left-hand end position (as illustrated in full lines) so that the service brake, which acts on the cardan shaft 72, is disconnected. In position 1 of the lever 43, the exhaust brake 12 is also kept in its non-applied position, as lever 40 of the exhaust brake valve 3 restricted flow of compressed air from the reservoir 1 through pipe 2, the exhaust brake valve 3 the additional valve 5 and pipe 6 to the pressure cylinder 7 so that the lever 11 of the exhaust brake 12 is kept in its left-hand end postion (as illustrated in dotted lines). When the lever 43 is moved from position I to position II, as illustrated in full lines in the figure, the levers 39 and 40 are rocked by the rod 41 into the position shown in the Figure. The pressure regulating valve 21, in this position still prevents passage of compressed air from the reservoir 1 to the pressure cylinder 23 so that the service brake remains inoperative. However, the exhaust brake valve 3 is opened and compressed air is allowed to pass via the additional valve 5 and the pipe 6 into the pressure cylinder 7 to rock the lever 11 and apply the exhaust brake 12; at the same time effecting movement of the lever 13, of the fuel injection pump 14 in an anticlockwise direction to shut off the supply of fuel to the engine. When the lever 43 is moved to the position III, the service brake is brought into operation, the exhaust brake remaining in its applied position. When the fuel pedal 55 and the clutch pedal 56 are not depressed, the rotary'valve 49 of the additional valve 5 takes up the position shown in the Figure whereby the spring 52 pulls the lever 51, fixed to the valve 49, against the abutment 53. When the fuel pedal 55 or the clutch pedal 56 is depressed, the rotary valve 49 is turned in an anti-clockwise direction and the exhaust brake is rendered inoperative. A modified construction of the control lever is described whereby it is possible to set into operation and again disconnect'the exhaust brake 12 and the service brake 28 either together or separately and in a sequence independent of each other. The exhaust brake valve 3 and the pressure regulating valve 21 may be combined in one single aggregate.

Title: A method of regulating the water content of a blended charge to be fed into a sinter machine
IPC: C22B1/20
Filed: 1963-07-22
Abstract: <PICT:1010488/C1/1> The admixture of water with the charge fed to a sinter machine is regulated in accordance with the gas permeability of the bed in the machine, which is measured by the pressure drop of a gas driven through the charge by a constant power fan.  The amount of water delivered by sprays 19 to a blended charge of ore in a mixer 4 is kept at a constant level by a coarse regulator 13.  The gas permeability of the bed on the sinter chain 3 is determined by the pressure drop, measured at 17, of a gas drawn through the bed by a suction fan 11, the pressure side of which is connected to the ignition hood 8.  The measuring suction box 9 extends the full width of the chain 3 and is narrow in the direction of the chain length. The gap between the underside of the chain 3 and the front edge of the box 9 is kept constant. Changes in the pressure drop at 17, corresponding to changes in the permeability of the bed, operate a fine control 15 for the water sprays 19. In a sinter machine having two or more layers of charge, one fan and suction box measures the gas permeability of the lower layer, and a separate fan and suction box measures the permeability of two or more layers together so that the addition of water to each layer can be controlled.

Title: A process for the manufacture and production of valuable derivatives of pyranthrone
IPC: C09B3/44
Filed: 1928-10-09
Abstract: 325,250. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 9, 1928. Samples furnished. Pyranthrone derivatives are prepared by replacing the nitro groups in nitropyranthrones or substitution products thereof either directly by halogen or by halogen, hydroxy, mercapto, cyano or thiocyano groups by means of the diazo compounds of the intermediately formed aminopyranthrones. Direct replacement of nitro groups by halogen is effected by the action of halogen or halogenating agents, if desired in an organic diluent, further halogenation being effected in addition by a more drastic treatment, for example at higher temperatures and pressures. The hydroxypyranthrones obtained from the diazopyranthrones mav be alkylated or arylated by the customary methods to yield particularly valuable dyes of which the ethoxy- and #-chlorethoxypyranthrones are the most importont. The following reactions are described in examples, dyeing shades of products being indicated in brackets :- (1) Mononitropyranthrone (Specification 23361/12) is converted to a monochloro derivative (orange) and a monobromo derivative by boiling with benzoyl chloride and benzoyl bromide respectively; (2) tetranitropyranthrone is obtained by introduring pyranthrone into 95 per cent nitric acid at 0-20‹ C. is converted to a tetrachloro derivative by treating with chlorine in trichlorbenzene; (3) monoaminopyranthrone obtained from the above mononitro derivative is converted to monohydroxy-, monoiodo- (orange), monochloro-, monobromo-, monocyano- (yellow-brown), and monothiocyanopyranthrone; (4) the monohydroxy derivative thus obtained is alkylated to methoxy- (red-brown), ethoxy- (red-brown), #-chlorethoxypyranthrone (red-brown), and the ethyleneoxy- (red-brown) and phenoxypyranthrones are also mentioned; (5) diaminopyranthrone obtained by reducing the pyranthrone nitrated by means of concentrated nitric acid in nitrobenzene at 90- 95‹ C., is converted to the dihydroxy-, and thus, to dialkoxypyranthrones (dyeing deeper shades than the monoethers) ; (6) tetraminopyranthrone obtained from the tetranitro derivative of (2) is converted to the tetrahydroxy-, and thus, to tetraalkoxypyranthrones (dyeing deeper shades than the monoethers) : the conversion of these di- and tetra-aminopyranthrones to the corresponding halogen and thiocyano derivatives is also mentioned.

Abstract: 1,124,844. Valves. DOLE VALVE CO. 28 June, 1966, No. 29046/66. Heading F2V. [Also in Division G1] A valve for alternatively putting into communication an inlet 21 and a chamber 34 or the chamber 34 and venting ports 29 comprises a bimetallic element acting directly on a valve pin 17 carrying a sleeve 32, the sleeve having a valve part 30 in which is disposed a member 23 having two heads 24, 25 co-operating with valve seats 26, 31 respectively, the sleeve 32 also carrying a flexible diaphragm 36 which allows movement of the sleeve 32 to raise either of the heads 24, 25 from its seat whilst sealing the chamber 34. The valve is described as being of use in a vehicle heating system whereby the vehicle engine inlet manifold vacuum is used as the controlling medium. The inlet 21 is connected to the inlet manifold, and communicates by way of a passage 28 in a plug 27 with the chamber 34. The chamber 34 is connected to an outlet (not shown) to control the vehicle heater. Thus with the head 25 engaged with its seat 31 and the head 24 raised from its seat, the chamber 34 is brought to the same reduced pressure as that prevailing in the inlet 21. In the other position for the valve, i.e. that shown in the drawing, the head 24 is engaged with its seat 26 and the chamber 34 is vented to atmosphere by way of the ports 30 and 29. A ridge 44 on the diaphragm 36 prevents the diaphragm from sealing against the plug 27. The bimetallic element 1 is in the form of a continuous zig-zag shape, the bight portions of which are secured in parallel arms 5 carried by flexible walls 8. Flexing movements of the element 1 due to changes in ambient temperature are communicated to the pin 17 by means of a member 7 whose position relative to the pin 17 may be adjusted by a nut 20.

Title: An improved electrical discharge system and method of operating the same
IPC: H01J25/06
Filed: 1938-10-10
Abstract: 523,712. Electron oscillators ; wireless circuits. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. Oct. 10, 1938, No. 29310. Convention date, Oct. 11, 1937. [Classes 39 (i), 40 (iii) and 40(v)] In an ultra-short wave oscillation generator a beam of electrons is passed through an oscillating field which causes cyclic variations of the electron velocities in the beam and results in groups of electrons travelling along the beam, these groups supplying power to a resonant circuit. In a self oscillator a beam formed by a cathode 4 and grid 20 enters a first "grid," resonator 21, with grids 9, 10 at its entrance and exit spaced apart a distance giving an electron time flight from 9 to 10 equal to less than a half cycle or a half cycle of the oscillating field or an odd multiple thereof. Some electrons are accelerated and some retarded by this resonator and after passing through the unipotential space 24 where the electrons form spaced groups they enter a second "anode" resonator 25 with grid 27 at its entrance and anode plate 12; the plate 12 may be replaced by a permeable part, the beam passing out of this second resonator. The time of flight between grid 27 and plate 12 is an odd number of quarter cycles given by 4n Œ 1. The bunched electrons impart oscillations to the second resonator ; its oscillation period is adjustable by making the walls resilient by means of slits, an adjusting screw 34 being attached to the plate 12. The oscillations in the two resonators are stated to take place wholly on the inner surfaces so that they are shielded from each other ; the resonators are earthed and are coupled by a loop 30. Radiations can be taken from this loop or if the slits in the walls of the resonator 25 were big enough power would be resonated thereby. Electrical or magnetic focusing may be used to direct all the electrons from the cathode through the resonator 21 and the grid 27. In a modification annular resonators 21<SP>1</SP>, 25<SP>1</SP>, Fig. 7, toroid in cross section are used with a ring-shaped cathode 50 carried on a plate 4. For work as an amplifier a grid loop 54 is carried by the first resonator and an anode loop 15 by the second. The first grid 9 may be in the form of wires running in one direction only and the grid 27 then has the wires in a direction at right angles to those in the grid 9. Specification 517,264 is referred to.

Apparatus for marking one or more curves on a member which will form a frame section, e.g. of a ship, comprises a carriage, a marking out device and a curve-follower device for controlling movement of the marking-out device the carriage being constructed to run along an edge of the member and the apparatus being arranged such that non-linearities of the edge are compensated. A plate 5 is marked with one or more curves 6 such that when the plate is bent to form a frame section, the desired curvature of the frame section is obtained when the curve 6 attains the form of a straight line (Figs. 2 and 3). The marking apparatus comprises a carriage 8 which has wheels 18 for rolling or geared engagement with an edge or a rack secured relative to the edge of the plate 5, a marking device 10, and a curve-follower device 26 for controlling movement of the marking device in accordance with a same-scale or reduced-scale curve which may have the form of a groove 3 cut in a plate 4. The plate 4, mounted on a carrier 22 which has roller engagement, as at 21, and geared engagement, as at 20, with the carrier 8, is movable with the carrier 8 but the ratio of the speed of its movement to the speed of movement of the carrier 8 relative to the plate 5 will depend on the gear ratio of the gearing provided. The scale of the curve 3 along the length of the curve corresponds to this gear ratio. Other arrangements of suitable curves or templates for the curve-follower to follow, are described.
