Headings A4B, A4H and A4U. Shelving assembled or disassembled by hammer blows, is built up from units each consisting of a platform 1 and four tubular uprights each having an upper part 4 of greater diameter connected to a lower part 5 by a conical neck 6, the part 5 of each upright being a force fit in the part 4 of the upright next below. The edges of the platforms are. U-shape having aligned apertures 16, 15 the larger funnel-shaped aperture 16 receiving the part: 4 and the smaller aperture 15 permitting passage of the part 5 so that each platform is clamped between the neck of one upright and the top of the upright next below. Cup shaped plastics feet have upright tubular elements 20 force fitted on the parts 5 of the lowermost tubular uprights, and tubular pegging elements (Fig. 2, not shown) have an out-turned flange engaging the upper surface of the uppermost platform. Side panels, having bent-over and preferably resilient edges engaging round the tubular uprights, have inwardly swaged holes for the suspension of file folder rails, and U-shaped guard strips; (Fig. 7, not shown) for the edges of the shelves have arcuate ends engaging the tubular uprights. In modifications a platform for coplanar mounting on an upright (Fig. 9, not shown) has a projecting apertured flange, castor wheels replace the feet, or the upper end of a tubular upright has a widened part and, to facilitate insertion, the lower end of the engaging upright, is conical. In providing a wheeled trolley a tubular tensioning bar has an enlarged head engaging the pegging element and screwed engagement with the wheel, or a bar handle is secured by pressing open a slotted extension at the top of the pegging element, by the head of the tensioning member, to press the slotted extension against the inside of the handle.

Abstract: 182,020. Bethell, T. F. Aug. 9, 1921. Packing eggs; unpacking.-Relates to frames, for packing eggs in boxes, of the kind described in Specification 6248/06. According to the invention, the blank of which the trough-shaped member is formed is incised at Aa, Fig. 1, so that flaps A may overlap and may be interlocked in that position when the blank is formed into a trough. Blanks, as shown in Fig. 2, interlock with slots B, Fig. 1, to form the cross partitions. The made-up frame may be surrounded by blanks which have flanges to turn under the bottom and may have upper flanges by which the device may be lifted from the box. The latter flanges may be scalloped to avoid contact with the eggs. The trays may be made of half the depth shown, and two may be used to enclose one layer of eggs, the upper one being inverted. A tray, formed of a number of perforated strips G, Fig. 9, with flanges H, may be used to protect the top layer of eggs from the top of the box, the whole being enclosed by a frame K. This device may be used to unpack the contents of the box, the frame and the upper tray being removed together and inverted, the eggs then resting in the perforations in the strips G.

Bales of fibrous material of different characteristics are opened and the bale material is distributed onto a stationary or slow moving conveyor 30 to form a stack of superposed horizontal layers of the material having the desired constituents of a blend, the stack is then conveyed to a compressing arrangement 35, 36 to compress the stack in at least the vertical direction and advanced to a blender comprising picking rolls 34 which rotate about a vertical axis and move horizontally across the front of the compress stack. As described, bales and part bales of different types of fibres are conveyed to opener (15) comprising a bladed opener rollers (17, 19) and a stripper roll (22). The feed to the bale opener is automatically controlled by photocell 31. The opened material is conveyed by an airstream in duct 23 to cage suction condensor 24 and is then delivered onto a reciprocating lattice 28. The lattice 28 operates so that the upper run moves in the same direction as the direction of instant reciprocation. The surface speed of the lattice 28 is the same as the reciprocation speed so that there is no relative movement between the underside of the lattice and the upper layer of the stack of material being formed on conveyors 30. The conveyors to opener (15) and opener 15 are stopped by photocell 32 when a stack has been formed. Conveyors 30 are operated when a desired stack has been formed to automatically feed the stack to the horizontal and vertical compressing conveyors 35 and 36 and bender 33.

IPC: G03C7/00
Filed: 1969-04-29
Abstract: 1,272,631. Spatial filtering. TECHNICAL OPERATIONS Inc. April 29, 1969, No.21884/69. Heading G2J. Preferential images of a predetermined order of diffraction are selected from a multi-record carrier 46 by selective illumination of the carrier 46 with one or more of a plurality of coherent light sources 49 , forming a Fourier transform of desired records and placing a spatial filter in the transform plane to pass only the required orders of diffraction. Each record on the carrier has a direction vector transverse to the optical axis of the system and alignable with each such vector is one of the light sources 49. The vectors have a predetermined angular separation from one to the other. Azimuthal alignment transverse to the optic axis is effected for each light source with its corresponding vector, and each beam of each light-source is angled with respect to the axis to locate the predetermined diffracted orders of each image on the axis. A carrier 46 formed to have records related to the colours red, blue, green and yellow is located in an optical system with respect to a transform lens 42 such that a Fourier transform of the records is formed. Six light sources 49 connected diagonally in pairs illuminate the carrier, each pair being angularly oriented with respect to another pair so that it is aligned with the direction vector appropriate to the red, green or blue colour of the records. The desired image or images is set up by illuminating the appropriate pairs of light sources, there being a spectral filter 54 with three pairs of filters 1 and 4, 2 and 5, 3 and 6. The distances 1-4, 2-5, 3-6 are set according to the wavelength of light to be transmitted to give the correct diffraction angle. A spatial filter 48 located in the transform plane only permits transmission of the selected orders of diffraction. In an alternative embodiment, Fig.2, the light sources 85 are located in a plate containing a plurality of light guides 78 each light guide being fed from an arc lamp 76 and having associated with each guide a determined spectral filter and a continuously varying neutral density filter 87. The filters may be individually adjusted by D.C. stepping-type motors via manual controls 96, 98, 100. The selected image received from the transform plane as passed by the spatial filter 112 is seen through binoculars 74. Preferably the angular geometry of the direction vectors is a 0-45-135 degrees configuration.

Filed: 1971-04-19
Abstract: 1324896 Automatic guidance of machines SIEMENS A G 19 April 1971 [27 Feb 1970] 22190/71 Heading G3R To prevent skewing of a machine guided along a rectilinear axis 11, a laser is arranged to project a beam parallel to the axis 11, and the machine is provided with two photo-electric detector assemblies lying in transverse axially spaced planes to sense individually any deviation of the machine from the axis. The machine may be a tunnelling machine, track straightening machine or construction plant. As shown two fan-shaped mutually perpendicular laser beams 4, 5 intersecting on a line 12 parallel to the axis 11 are projected along the machine 1. The machine 1 carries two axially spaced photo-detector assemblies 2,3. Each assembly comprises four photo-cells e.g. 21-24 arranged as perpendicular pairs. When the respective laser beams 4, 5 are midway between a pair of cells 23, 24 and a pair of cells 21, 22 a zero output is produced from a differential stage but as soon as the cells of a pair become differently illuminated a corrective signal is produced by the respective differential stage. Although two pairs of mutually perpendicular photo-detectors have been shown only one pair is needed if the machine can move in one direction only. To compensate for rotation of machine 1 which would cause photo-cells 21-24 and 31-34 to give false readings a sensing system is employed. This sensing system comprises a pendulum 10 pivoted at the axis 11 of the machine and making sliding contact with an arcuate conductive rail 7 which is earthed at 18. A voltage is applied between the ends 8, 9 so that any displacement of pendulum 10 produces a signal that can correct the angular alignment of the machine.
