Title: Improvements in or relating to apparatus for scanning code markings
IPC: B07C3/14
Filed: 1964-04-21
Abstract: 1,059,498. Statistical apparatus. SIEMENS & HALSKE A.G. April 21, 1964 [April 30, 1963], No. 16566/64. Heading G4M. Articles such as letters are provided with two sets of radiation-emissive marks, e.g. one set for controlling automatic sorting of outgoing mail and the other set for controlling sorting of incoming mail. The two sets of marks may be applied in different areas of the article, or they may overlap, in which case the two sets must have different characteristics, e.g. one being phosphorescent and the other being fluorescent. The two sets may alternatively emit light of different wavelengths or respond to different excitation wavelengths. Fig. 1 shows apparatus for sensing either phosphorescent or fluorescent marks. A mercury vapour lamp 5 is spaced from the sensing station by a distance such that only the phosphorescent marks excited by lamp 5 are still emitting radiation when they reach light guide 7 leading to photomultiplier 3. To sense the fluorescent marks, radiation from a lamp 9 passes through a filter 13 and portion 8 of guide 7 to excite the marks, and a filter 10 is inserted so as to pass only radiation emanating from the fluorescent marks.

Title: Improvements relating to the suppression of noise from electromagnetic apparatus
Inventor: ENNIS ARTHUR SAMUEL
IPC: G10K11/175
Filed: 1959-05-14
Abstract: 897,859. Transformers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 16, 1960 [May 14, 1959], No. 16590/59. Class 38 (2). Noise from a transformer or other electromagnetic apparatus accommodated within a tank containing liquid coolant is reduced by producing in the coolant vibrations of the same frequency as, but in phase opposition to, the noise producing components. The vibrations may be produced by one or more moving coil or moving iron vibrator units with their moving elements coupled to the tank walls, or in contact with the coolant. The vibrators may be energized by small alternators mounted on a common shaft and producing outputs corresponding to the various noise frequencies, angular adjustment of the stators varying the relative phases. Alternatively, the noise components may be magnetically recorded on a tape or disc and the reproduced signal fed to the vibrators, the reproducing head for each component being adjustable for phase-control. In a further embodiment, odd harmonics are produced by a magnetically-saturated transformer, and/or a rectifier circuit is arranged to produce even harmonics. Phase-shifting circuits are provided, together with resonant circuits tuned to the required frequencies. In another arrangement, separate oscillators may produce the required frequency components, or a square-wave generator may be provided with filter and phase-shift circuits. Alternatively, the tank walls may be vibrated by mounting a dynamically-unbalanced rotating shaft thereon, driven by a synchronous motor from the main supply. Phase adjustment may be produced by varying the phase of the motor supply or by angularly adjusting the mass producing unbalance of the shaft. An arrangement in which electric signals derived from the sounds in the coolant are utilized in a feed-back system to produce the noise-suppressing vibrations is also referred to. Specification 726,910 is referred to.

Filed: 1946-05-31
Abstract: 612,863. Hopper feed for cartons. VALLEY PRODUCTS (LYE), Ltd., and TEARNE, W. May 31, 1946, No. 16666. [Class 78 (i)] A hopper 10 for delivering a definite quantity of powdered materials into cartons comprises a discharge means (gates 17, 18) for cutting off the flow of material which are opened against spring force 42 by mechanical means such as cam 32 on rotary shaft 46 and are closed under the influence of the spring against fluid pressure in a cylinder controlled by a regulating valve. In the Figures, material is fed from hopper 10 by agitating means 11 and rotary paddles 14 to carton 16. Its passage is controlled by pivoted blades 17, 18, Fig. 2, which pivot about points 20, 21 being fixed to short arms 24, 25 which are pivoted to links 26, 27. The latter are pivoted at 28 and are moved to the left at each rotation of shaft 46, the motion being transmitted, through cam 32 and its roller 33 fixed thereto, to horn 34 which in turn pushes (adjustable) screw 31 fixed on slide bar 29 and, since the latter is fixed to the pivot 28 on which the links 26, 27 turn, causes the blades 17, 18 to swing open and permit the passage of material. Slide bar 29 is connected at 47 to piston 49 so that as the movement goes to the left it goes quickly, because the air presses out the large valve 51 against the atmosphere. Return movement to the right under springs 42 (Fig. 2) goes slowly, because large valve 51 is forced back by the atmosphere into place and air is admitted very slowly through time regulatable valve 51 so that blades 17, 18 return slowly to the closed position and thus permit a desired quantity of material to fall. Dribble opening 19. A final dribble of material is permitted through the gap 19 shown between the blades 17, 18. It is controlled by slide 36 which is coupled to and is opened by the horn 34 under the influence of the cam, but returns independently thereof in a manner not described.
