Title: Pneumatic conveyor apparatus having a pressure container for pulverulent or granularmaterial
IPC: B65D88/70
Filed: 1962-12-18
Abstract: 1,009,627. Pneumatic conveyers. H. BRAUNANGOTT. Dec. 18, 1962 [Dec. 19, 1961], No. 47777/62. Heading B8A. In pneumatic conveyer apparatus having a pressure container 1, Fig. 2, for feeding pulverulent &c. material to a conveyer line 9, the container has a flexible lining 4 which is inflated by compressed air for loosening the material, the air escaping at the lower end of the lining to mix with the material falling into the conveyer line 9. The lining 4 is attached at its upper end to the container wall and compressed air is supplied as by an annular pipe 5 with radial branches 15. In one example (not shown) the lining 4 is not otherwise supported internally but in the example shown the lining 4 is rigidly held in recesses 14 of the container wall by tubular stays 10 attached to a tubular ring 11 at the top of the container and extending generally conically towards the outlet 9. The stays 10 have perforations 13 for the introduction of loosening air in a direction generally tangential to the internal conical surface the air being supplied to the ring 11 at inlet 12. Elastic sleeves 16 may be provided over the stays 10 and have resiliently openable perforations 17 aligned with the holes 13 to operate as check valves which prevent clogging due to back flow of material into the stays 10.

Title: Improvements in or relating to Vehicles and Vehicle Couplings
Inventor: WRIEDT ALFRED
IPC: B61G5/02
Filed: 1966-10-25
Abstract: 1,158,919. Rail vehicle draw gear; communication platforms; handrails. A. WRIEDT. 25 Oct., 1966 [28 Oct., 1965], No. 47921/66. Headings B7L and B7T. Rail vehicles 1 and 2 are each provided with two longitudinally movable link rods 6, 8 and 7, 9 interconnected by joints 12, 13, and locking members 14-17 releasably engage with locks 18-21 as shown, the arrangement being such that on a curve the outer rods are electrically or mechanically unlocked as in Fig. 1b. In Fig. 1 the vehicles are shown on a straight track and the lock operating switches 26, 27 are open so that neither of the locks 18, 19 controlled respectively by coils 22, 23 are open. However, when the vehicles round a curve their inner corners approach one another and the switches 17, 27 are closed, as in Fig. la, to energize coils 22, 24 to open the locks 18, 20 as in Fig. 1b. The entire draft load is then transferred to the still locked link rods 8 and 9 so that the compression on these rods on the inner curve disappears and the rods 8, 9 move to open the switches 27 and so on so that the locks 18, 20 are released. These locks however cannot re-engage because the vehicle outer corners have moved still further apart as in Fig. 1c and may only re-close by snapping over 14 and 16 when the vehicles come together again on the straight, as in Figs. 1d and le, not shown. In a modification only one of the two vehicles may be provided with switching devices 26, 27 the other unlocking devices on the other vehicle being actuated in parallel. Figs. 2-2b (not shown) illustrate electric switching and locking devices, and Figs. 3-3c (not shown) illustrate a mechanical lock. The vehicles may have loading platforms designed as roller tracks formed of rollers arranged transversely with respect to their bodies, and when such an arrangement is used the portions of the link rods 406, 407, Fig. 4, jointed at 412 and protruding from the vehicles act as carriers for an additional roller bearing arrangement between the ends 403, 404 of the vehicles. In this construction a rod 432 between the joints 412, 413 supports rollers 433, and additional rods 434, 435 supported at their ends on sleeves such as 436, 438 slidable under spring control on the link rods 406, 407 also mount rollers. Longitudinally displaceable or telescopic handrails 450-453 are supported on the vehicle sides. Figs. 5 and 6 (not shown) illustrate variations of this roller supporting arrangement in which the intermediate rollers 482, 483 are either prevented from moving relative to the adjacent vehicle until the link rods 406, 407 have completed one half of their maximum travel, or the intermediate rollers are swung into the gap immediately the link rods start to move. Bridge members or load bearing frameworks 490, Figs. 4, 4a, mounted on the intermediate roller assembly 434 and 435 are slidably supported by the central rod 432 and the adjacent vehicle and give additional support to loads as the gap widens.

Title: Improvements in or relating to colour television cameras
Inventor: RYLEY DEREK VERNON
IPC: H04N9/093
Filed: 1969-10-01
Abstract: 1,273,193. Colour television cameras. MARCONI CO. Ltd. 6 July, 1970 [1 Oct., 1969], No. 48168/69. Heading H4F. A multiple-tube colour television camera is provided with means for correcting errors in picture registration which can be brought into operation in conjunction with the use of a special "test card" when errors are detected, the means comprising logic circuits receiving the video outputs from two tubes and recording the time difference between them for use to correct the line and field deflections. By use of a triangular pattern on the test card (Fig. 6) and selection of scan lines L1, L2 the signs of the time differences A1-A2 and B1-B2 may be stored. If these are the same, indicating a horizontal registration error, the line scan of one tube is shifted in the appropriate direction to effect correction, and if different the field deflection of that tube is corrected. Thus composite errors are corrected by successive adjustments. For three- or four-tube systems two or three such correcting arrangements are used to adjust the registration of two or three tubes to a "reference" tube. By the use of a number of triangular patterns spaced over a test card it is stated that corrections may be made to height and width, and linearity and skew in addition.

Title: Scuffed container detector
IPC: G01N21/90
Filed: 1974-11-07
Abstract: 1482796 Detecting roughness photo-electrically BARRY-WEHMILLER CO 7 Nov 1974 [14 Nov 1973] 48254/74 Heading G1A Apparatus for detecting surface roughness on transparent containers comprises: means to move containers in single file through a detection station; a source arrangement directing a slanting narrow light beam down through a container; means spaced horizontally from the light beam to detect light scattered by any illuminated surface roughness of the container; and means generating a signal when the detected light exceeds a predetermined intensity. A conveyor 10 Fig. 1 moves transparent containers 11 towards a pair of star wheels 14, 15 wherein they are constrained by a belt 20 to traverse a detection station. At an inspection point each container in turn interrupts a light beam illuminating a photo-cell 24, which triggers a timing pulse generator, (58) Fig. 4 (not shown) to operate a visual timing indicator (59). Light from a short-filament lamp 36, imaged at F behind an adjustable sharpedged aperture 39, is collimated at 46 and reflected down by the front surface 47 of an adjustable mirror 48 in the form of a narrow beam inclined at an angle A (15-35 degrees) to the vertical container axis, so that when admitted by a slot 27 in the upper wheel 14, it penetrates the container 11 and illuminates its opposite wall in a zone where scuffing is expected. A photo-multiplier, 34 Fig. 3, receives any light scattered horizontally at an angle B (20- 40 degrees) to the normal at the illuminated surface, its field of view being restricted, by apertures 29 and 32. The sensitivity of the arrangement is controlled by a Ronchi grating in the aperture 29, and, if the containers are coloured, a filter may be used in the aperture 32. The photo-multiplier 34 output after amplification at (54), Fig. 4 (not shown) is applied to a comparator (55) where it is compared with a threshold signal derived from an adjustable element (56). Any output from the comparator (55), when gated (at 60) by the timing pulse, operates a visual reject indicator (62) and a reject counter (63), and energizes a solenoid 18, Fig. 2 which actuates a suction cup 17. The faulty container 11 is thus held in the star wheels 14, 15 Fig. 1 until released by a reset device (not shown) and so deposited in a rotating collection table 19. Acceptable containers 11 proceed, unrestrained, from the star wheels 14, 15 to a carry-off conveyor 10A
