Title: Improvements in apparatus for conveying powdered, or granular, material from bulk and delivering it in measured quantities into a container
IPC: B65G65/00
Filed: 1928-02-09
Abstract: 311,672. Newall, S., and Crosfield &. Sons, Ltd., J. Feb. 9, 1928. Filling granular materials into containers. - In apparatus for conveying powdered or granular material from bulk and delivering it in measured quantities into a container, the material is fed from a container 20 onto the upper portion of the periphery of a rotatable flanged drum 1 and is carried thereby towards a hopper 69 for delivery into a container 56. The thickness of the layer of material on the drum is determined by a compressing roller 40 and an adjustable scraper 45, and a predetermined quantity of this material is scraped off the drum by a scraper 55 which moves, when scraping, faster than the peripheral speed of the drum. The machine is driven by a chainwheel 9 which is connected to a shaft 6 by a sliding clutch 13 operated by rod 15 and handle 17. The drum 1 is driven by a worm 5 and worm-wheel 7 and skey-gears 30, 31 drive a shaft 29 from the shaft 6. A chain wheel 28 drives, by a chain 26, a chain wheel 27 connected to a shaft 24 provided with agitating rods 25 which rotate, between rods 32 projecting from the sides of the container 20. The shaft 29 drives the roller 40 by a chain 39 and a gear wheel 63 drives a similar wheel 64 connected to a shaft 61 on which a crank arm 60 is mounted. This crank arm is slotted at 59 to adjust the stroke of the scraper arm 57 which is provided with projecting rollers 69 and springs 71 for drawing the scraper onto the drum. A lever 73, pivoted at 74 and provided with rollers 77 is brought into contact with a ratchet wheel 76 by means of a spring 78 and the rotation of the wheel causes the projection of the ratchet to impinge on the rollers 77 to vibrate the lever so that a hammer 72 on the latter strikes the hopper 68 and dislodges any material adhering to the sides. The roller 40 is adjustable relatively to the drum by a screw 37 which works against the pressure of a spring 38 and the scraper 45 is adjustable by a screw 46 which is rotated by a shaft 49. The material from the container 20 is fed onto the drum where it is compressed by the roller 40 and the thickness adjusted by the scraper 45. During clockwise rotation of the crank 60, the rollers 69 contact with the rim 1<a> of the drum and raise the scraper during the lower half revolution and during the top half revolution the scraper descends onto the periphery of the drum and is rapidly withdrawn to the position shown in the Figure where it is discharged into the hopper 68 to fall into a receptacle 56 which may be a bag, tin &c. placed in position at each discharge. Two drums may be used to fill one bag &c., the bag being moved from one drum to the other to catch the discharged material. The bottom 42 of the container 20 is adjustable toward the periphery of the drum.

Title: Apparatus for ascertaining the value of a desired function of a variable
IPC: G06G3/00
Filed: 1939-02-09
Abstract: 525,268. Calculating-apparatus. BROIDO, D. Feb. 9, 1939, No. 4276. [Class 106 (i)] [Also in Groups XL and XXIV] Relates to photo-electric apparatus of the kind described in Specification. 521,471 for determining the y values of graphs. According to the invention, the graph comprises a transparent part 2, Fig. 1, and an opaque part 2a, separated by a line 1 constituting the graph proper, the photo-electric scanning device comprises a lamp on one side of the graph and a cell 3 on the other side in a casing formed with a vertical slot 5 and surrounded by a rotating cylinder 6 formed with a helical slot 7 shown developed in Fig. 2. This device is moved to any x value of the graph or the graph is moved relativelv thereto, and the device is then moved up and down by a, rack and pinion 13, 14 driven by a differential gear under control of the cell whereby ultimately at the end of a scanning cycle the top of the slot 5 coincides with the graph line 1 and the y value can therefore be indicated by an indicator attached to or operated by the rod 4 carrying the cell. The differential gear comprises a pinion 17 driven by a wheel 21 and another pinion 18 driven at twice the speed in the opposite direction by a wheel 26. The scanning cylinder 6 is rotated by pinions 9, 10 at the same speed as the wheel 21. A clutch 25 is interposed between the wheel 26 and the pinion 18 and is normally held in engagement by a spring 29. The scanning spot is determined by the intersection of the oblique and vertical slots, and the scanning cycle begins with the scanning spot at the bottom of the slot 5. If the scanning spot is in the dark region of the graph, the clutch remains in engagement and the differential gear drives the cell up. When the scanning spot reaches the transparent region of the graph, an amplifier 32 in circuit with the cell causes a relay 30 to disengage the clutch, the drive of pinion 18 is stopped and the cell is moved down at the same speed as the scanning slot is moving up relatively thereto, with the result that at the end of the cycle the top of the slot 5 coincides with the graph line 1. At the end of each cycle a cam 37 re-engages the clutch. In a modified clutch, Figs. 5 and 6, the relay 30 trips a catch 55 releasing a pawl 58 to engage and stop a ratchet 61, whereupon spring 68 is stressed and pins 65 on the clutch 25 overtake holes 69 in the ratchet and the clutch is disengaged by a spring 64. At the end of a scanning cycle, the clutch is re-engaged by a cam 70 and the pawl 58 is returned to original position by a cam 71. In a modification of the scanning mechanism, the rack 13 is driven by a source of constant speed through a variable speed reversing drive set by a differential gear under the control of the cell. In another modification, the scanning device comprises two separate cells and ultimately takes up a position with the graph line between the two cells.

IPC: B62D17/00
Filed: 1937-02-15
Abstract: 467,077. Road-vehicle undercarriages. DAIMLER-BENZ AKT.-GES. Feb. 15, 1937, No. 4479. Convention date, Feb. 14, 1936. [Class 108 (ii)] In an arrangement for adjusting the camber and/or caster of independently-sprung vehicle wheels, particularly those mounted by quadrilateral linkages, an eccentrically adjustable pivot, which is itself displaceable axially of the eccentric, is included in one of the wheel guiding-elements, e.g. between a guiding-link and a knuckle pivot, so that the inclination of the wheel-carrier or knuckle pivot can be adjusted in planes parallel to and transverse of the direction of travel. In the construction shown, the upper suspension links c are connected to the wheel-carrier e by simple pivots f, and the lower links d by means of ball joints g. Each upper link comprises a pair of spaced arms c<1>, c<2>, Fig. 4, adapted to form a sleeve embracing an inner sleeve i which in turn has an eccentric bore to receive one element m of the pivot f. At its outer end the spindle m is provided with a fork n<1> n2 eccentrically disposed in relation to the axis of the spindle and fitted with a pin p on which the eye member f pivots. Either rotation of the eccentrically bored sleeve i, or rotation through 180‹ of the fork n<1>, n<2> effects a displacement of the upper pivot of the wheelcarrier in the longitudinal direction of the vehicle, and, by utilizing both adjustments, the angle of caster may be varied accurately through a considerable angle. The inner end o of the spindle m is screw-threaded and cooperates with an inner thread on the sleeve i so that an axial adjustment of the spindle can be effected by relative rotation of the parts o, i. Alternatively, the longitudinal adjustment may be effected by screw-threads and the transverse adjustment by means of eccentrics, while the type of joints employed to mount the wheelcarrier may also be varied.

The target 18 of an image orthicon tube comprises a lead-glass membrane which is siliconized or sulphurized to reduce its effective surface conductivity. As shown, the target 18 is mounted between a mesh screen 34, in the end of accelerating electrode 30, and beamdecelerating electrode 22.The lead glass membrane may comprise 60% SiO 2 ,15-20% PbO, 12-15% Na 2 O,2-5% Al 2 O 3 and 0.5% As 2 O 5 . It may be sealed to a support ring of a nickel-iron alloy within a box of pure platinum, fused quartz or platinum-coated material, by heating for 3 minutes at 720‹ C. The temperature is then reduced to 70‹ C. and a drop of a benzene solution of dimethyldichlorosilane is placed in the box which is kept closed for 1 minute for deposition of two monolayers of silica on the target. The image orthicon tube may be baked at 385‹ C. for 1 hour, and caesiated at 165‹ C., but the oxygen-flushing step is omitted with a siliconized target. Alternatively, the lead glass membrane may be sealed to its support in a box which has been previously sulphurized by volatilizing powdered sulphur therein during a bake of 10 minutes at 800‹ C. The target is sulphurized during sealing at 720‹ C. Lead glass targets are said to have an operating life of over 500 hours, and the siliconizing process increases the secondary emission ratio thereof.
