Title: Fibrous carbon articles
Inventor: BICKERDIKE ROBERT LEWIS
IPC: C04B35/83
Filed: 1959-07-02
Abstract: A shaped carbon article comprises carbonized cellulosic fibres Shaping may be effected before, during or after carbonizing.  A filler may be incorporated in the article from a solution or vapour or as a solid.  The filler may be uranium oxide.  Carbon may be deposited on the fibres after carbonizing from vaporous benzene or during or after carbonizing from phenol-formaldehyde resin or furfuryl alcohol.  The fibres may be first mixed with powdered phenol-formaldehyde resin or impregnated with furfuryl alcohol, carbonized and then subjected to deposition of carbon from benzene vapour.  The article may be graphitized. The graphitized article may be further subjected to deposition of carbon from benzene vapour.  A tube having an intermediate layer of higher density may be preformed before carbonizing by arranging a loose layer of cellulosic fibres between an inner rubber tube and a tube of loosely woven cellulosic material moistened with furfuryl alcohol and a second loose layer of cellulosic fibres between the tube of loosely woven cellulosic material and an outer rubber tube and applying hydrostatic pressure. Alternatively, rings of material woven to have an inner dense zone and impregnated with furfuryl alcohol or phenol-formaldehyde may be assembled on a former and heated under axial compression to effect polymerization. Compressed cotton wool may be carbonized in lamp black (Example 1), cotton wool may be compressed in a die during carbonizing (Example VI), a pack of cloth discs may be carbonized under mechanical pressure in an atmosphere of nitrogen (Example VII), rings of woven cellulosic yarn containing furfuryl alcohol (Example IX) or phenol-formaldehyde resin (Example X) may be stacked on a spindle and heated with slight axial pressure to form a consolidated tube before carbonization, a cylinder formed from alternate layers of discs comprising an inner portion of woven cellulosic material containing uranium oxide and an annular portion of similar but coarser material free from uranium oxide and discs of the coarser material free from uranium oxide may be carbonized under slight axial compression (Example III), pellets formed from cotton fibres containing uranium oxide surrounded by cotton fibres free from uranium oxide may be carbonized in lamp black (Example IV). An ungraphitized product may have a density of 1.58 g./c.c., a Young's Modulus of 3.41 X 106 p.s.i., a breaking stress in bending of 11.6 tons/sq. inch, a compressive strength in the direction of the fibres of 13.9 tons/sq. inch, a compressive strength perpendicular to the direction of the fibres of 19.5 tons/sq. inch, and a permeability of 2.12 X 10-8 cm.2/sec.  A graphitized product may have a density of 1.65 g./c.c., a Young's Modulus of 1.96 X 106 p.s.i., a breaking stress in bending of 4.7 tons/sq inch, a compressive strength in the direction of the fibres of 6.1 tons/sq. inch, and a compressive strength perpendicular to the direction of the fibres of 8.1 tons/sq. inch.

Title: Improvements in or relating to blank-forming mechanism for envelope making machines
Inventor: HEYWOOD VINCENT EATON
IPC: B31B23/00
Filed: 1952-09-16
Abstract: 709,546. Making envelopes. UNITED STATES ENVELOPE CO. Sept. 16. 1952, No. 23226/52. Class 94 (2) Diamond-shaped blanks 20, Fig. 9, are produced by successive oblique cuts 19 of a continuously fed paper web 18 and the obliquity of the cut and direction 18<SP>1</SP> of the web feed may be adjusted independently, but about the same axis a, for handling different widths of web and blank sizes, while maintaining the web edge in intersection with said axis. The blanks thereafter, whatever their size, proceed in the direction, 21, of their minor axis for trimming at 24, scoring at 25 and notching operations at 26, 27 and subsequent gumming and folding. The continuous web from roll 47, Fig. 3. is fed by driven rolls 54, 56, 57, 58, Figs. 2 and 3, the latter of which comprises a fixed and an adjustable portion to accommodate different web widths. The rate of feed may be adjusted by changing the replaceable driving gear 64 which drives gear 66, on the shaft of roll 57, through an adjustable idler gear 65. Initial threading of the web is facilitated by .means operated by handle 75 to raise the roll 58. In a similar way roll 56 may be withdrawn from roll 57. The web is severed obliquely during its passage between further pairs of feed rolls mounted on shafts 86, 87 and 96, 99 respectively. The feeding mechanism so far described is mounted on a plate 51 which may be swivelled about the axis a to the appropriate angular feed position, indicated on scale 129, and clamped by bolts 128. The web-severing mechanism is mounted on a base 104 which may be independently swivelled about the axis a and clamped by bolts 126. It comprises a stationary upper blade 119, Fig. 8, secured to a block 120 by bolts 122 and adjustable by screws 123, and a rotary blade 116 seated on a flat surface 114 on the shaft 108. The blade 116 is adjustable by screws 118 and secured by bolts 115. The stationary blade is preferably set slightly out of parallel with the rotary knife 116. Means are described for adjusting the lateral position of the web supply roll relative to the datum axis a Figs. 19, 20, 21 (not shown). The direction of movement of the severed blanks is changed by their engagement with the unrelieved portions of rolls 131, Fig. 2, and rolls cooperating therewith, which take over the feed from the rolls on shafts 96, 99, which have suitably synchronized relieved portions. The score lines 25 are produced on the blanks by adjustable discs 154 and the portions 24 trimmed off by, adjustable blades 156, the shaft carrying these members being arranged to be raised when adjustments are to be made. Fig. 11 (not shown). The notches 26, 27 are cut bv angular cutters on hollow shafts 166. 167 respectively, through which the cuttings are drawn by suction from pipes 186. Means are provided for adjusting the axial and circumferential positions of the cutters, Figs. 15 to 18 (not shown).

Title: Improvements in or relating to optical objectives of variable focal length
IPC: G02B15/02
Filed: 1950-09-22
Abstract: 689,206. Objectives. COOK, G. H., and TAYLOR, TAYLOR & HOBSON, Ltd. Aug. 30, 1951 [Sept. 22, 1950], No. 23298/50. Class 97 (i). A corrected optical objective of variable focal length comprises an axially movable divergent member 2 located in front of a stationary convergent rear member and behind an axially movable convergent front member 1 and, in each operative position, the equivalent focal length of the divergent combination formed by the front two members bears to that of the complete objective a ratio between 8 and 13 times the reciprocal of the f number of the objective, the virtual image of a distant object formed by such divergent combination having a constant axial position relatively to the stationary rear member throughout the range of variation of the objective focal length. In the form shown, the divergent member 2 is a doublet having a collective cemented surface and is located between a convergent doublet 1 having a dispersive cemented surface and the rear member which consists of a divergent meniscus doublet 4 between a simple convergent lens 3 and a convergent doublet 5. This rear member may have a focal length between Fo and #FoFm, where Fo and Fm are respectively the minimum and maximum values of the objective focal length. Preferably, also, the ratio of the focal length of the convergent front doublet 1 to that of the divergent middle member 2 is between 1 and 1.2 times the value of the expression (1+#Fm/Fo). Focusing for near objects is effected by axial movement of the convergent front doublet 1 independently of the middle and rear members. The diaphragm of the objective is located in or near the rear member and the diameters of the front two members 1, 2 are made larger than is necessary to accommodate the full axial beam so that the relative aperture of the objective is determined solely by the diaphragm and remains constant throughout the range of variation. Optical data are given for the example shown.

IPC: B30B11/16
Filed: 1960-08-19
Abstract: 965,758. Pelleting forage crops. MASSEY-FERGUSON Inc. Aug. 19, 1960, No. 23400/60. Heading A2B. [Also in Divisions B5 and F2] A machine for treating cut agricultural crops e.g. forming pellets of hay &c. from a flow of material being advanced through compressing means, includes a sensing device which varies the speed of the treating means according to the amount of material entering the machine. The invention is described with reference to a hay pelletizing machine and in this, hay is gathered by the usual pick-up reel 21 and guided by conveying plates 28 between upper and lower converging belt conveyers 30, 32. The conveyer 32 pivots about a shaft 45 and is supported at its inner end by a roller 90 which runs on the hay. Pressure exerted by the roller 90 on the hay is adjustable by means 95, 96. The hay already compressed, is formed into pellets between the involute teeth of gears 51, 52, plates (61) 62 confining the material above and below the teeth. Rotary blades 132, 141 knock the pellets from between the teeth for removal by a conveyer 70. Variations in the height of the roller 90 due to the material passing beneath are transmitted by a cable 120 to the control arm 110 of a variable speed device 100 (see Division F2) in the drive between the motor 15 and the gears 51, 52. An increase in the amount of material flowing causes a speed-up of the gears.

Title: Improvements in dump-car door controlling mechanism
IPC: B61D9/02
Filed: 1929-07-30
Abstract: 337,447. Pressed Steel Car Co., (Assignees of Reeder, N. S.). March 1, 1929, [Convention date]. Operating vehicle doors by tilting of vehicles.- In mechanism for controlling the opening and closing of dumping-car doors by the tilting movements of the dumping-car body, whereby a door locking device is released at the beginning of the tilting movement to allow the door to open, the locking device is designed to move by gravity into the locking position when the car body returns to its normal position. The car body 2 is mounted upon the underframe 3 provided with bearings 7 for the trunnions 36 secured to the tiltable part 2. Doors 5 are hinged to each side of the body part 2, and stakes 6 secured to the door carry the locking members 28. The door operating mechanisms are each mounted on a transverse member 16 of the underframe, and comprise a member 17 pivotally mounted on the bolster 16, a member 21 mounted on the underframe adjacent to the door, and a connecting link 19. The locking mechanisms each comprises a wedge-shaped member 28 which is slidably positioned in the door stake 6, the face of the wedge projecting normally beyond the door hinge to prevent rotation of the door. When the body tilts to the right, as shown in Fig. 5, the member 14 on the car body engages the forked member 17 and the lever mechanism is operated as the tilting continues. At the same time an extension 24 of the stake 6 is moved faster than the member 23 of the rotatable part 21 and the member 23 engages the locking member 28. Further movement of the body part moves the member 28 upwards until the door is free to open. On the left-hand side this movement of the body part 2 has caused its disengagement of the door operating mechanism for the door on that side. With the continued tilting movement of the car body the door opens by gravity and the weight of the material being discharged. As the car body 2 returns to its horizontal position, the member 14 causes the member 17 to rotate and move the member 21 outwardly and upwardly to move the door about its hinges. The door reaches its closed position before the body is again horizontal, and at this point the locking- wedge engages the door and secures it in its closed position. Springs 26 are provided to hold the bifurcated parts 18 of the members 17 in position to receive the members 14 of the car body upon the return of the body to horizontal position. The construction of the locking wedge 28 is shown in Fig. 8. The door hinge extension 29, 30 and members 32 of the car body conform in contour to the portions 33 and 34 of the face of the wedge 28. When these parts are in engagement the door is secured in the closed position. The extension 35 of the wedge engages with the member 23 of the operating linkwork, and when the wedge surface 33 is free 'of the part 29 of the door hinge the door is free to open.
