Title: Improvements relating to wrapper feeding devices for caramel wrapping and like machines
IPC: B65B41/18
Filed: 1925-12-01
Abstract: 262,588. Baker Perkins, Ltd., Harris, R. A., and Martin, H. E. Dec. 1, 1925. Feeding and registering webs.-In caramelwrapping and like machines employing a paper web that is intermittently fed forward and cut, feeding of the correct length at each operation is ensured by means comprising an electric switcharm or the like which controls a device for arresting the web each time the switch arm coincides with one of a series of perforations disposed at regular intervals in the web. In the machine shown in the Figure, the web a is drawn from a roll b by means of feed-rollers d, e, the roller d being operated intermittently by means of a pawl g on a rocking arm h connected by a link i to a driving-disc j. The web passes through a guide k and beneath a rubber-faced brake constituted by the pivoted armature l of an electro-magnet m, the brake being normally out of contact with the web. The electromagnet is in circuit with a contact arm p and a contact o, the contact arm being controlled by perforations in the web, and the contact being opened and closed by a segmental rim n on the disc j. The perforations occur at intervals equal to the lengths into which the web is cut, and when the web bears repeated imprints the perforations are placed midway between the imprints. When a perforation coincides with the contact arm the brake is applied and the web is arrested, the feed-rollers slipping. Contact rollers may be arranged under a contact roller on the arm p. The web is tensioned by a guide u on a spring-urged lever t which is rocked by a cam v to relieve the tension during operation of the feed-rollers. Specifications 102,488, 218,346 and 218,608 are referred to.

Title: Improvements relating to photographic copying cameras
IPC: G03B27/34
Filed: 1949-11-26
Abstract: 681,190. Photographic copying cameras. EVANS, O. (Powers Photo Engraving Co.). Nov. 26, 1949, No. 30376/49. Class 98 (i). A focusing scale for a photographic copying camera comprises a rotary member having a number of convolutions thereon uniformly spaced from each other and providing an elongated scale, index markings thereon, and a series of inclined lines between adjacent convolutions, the inclination of the lines with respect to the adjacent convolution increasing progressively towards one end of the scale. The camera preferably has a film support 3, Fig. 1, a copy support 8, and a lens 6 between the supports, two scale members 15, 32, of the kind set out above, one rotated by relative movement of the film support 3 and lens 6 and the other by relative movement of the lens 6 and copy board 8, and two independently-adjustable pointers for each scale member, one for reducing and one for enlarging. The film support 3 is fixed with respect to a bed-plate 2a carrying rails 1 on which the lens board 7 and copy-holder 8 are movable. A rack 9 supported by the filmholder 3 and a bracket 10 is engaged by a gearwheel 12. A shaft 13 (see also Fig. 3), journalled in a bracket 11 on the lens board 7, carries at one end the gear-wheel 12 and at the other end a spiral gear 16 meshing with a pair of spiral gears 17 which are fast on rods 18 journalled in bracket 11. A carriage 21 has an internallythreaded bore engaging one of the rods 18, which is also threaded, and sliding on the other rod 18 which is unthreaded. Gears 26 fast with rods 18 engage each other to eliminate backlash. Shaft 13 also carries a disc 14 carrying a spiral scale. The arrangement is such that when the lens board 7 moves a distance equal to the focal length of the lens 6, the disc 14 revolves once. The scale is read by a pointer on carriage 21. The main scale is calibrated in accordance with the nominal focal length of lens 6, but departures from the nominal value are allowed for by adjusting the pointer and obtaining readings with the aid of lines between and inclined to the convolutions, and also, if necessary, by replacing gear 12 by a gear with a different number of teeth. Since the focal length of lens 6 may have different values for reducing and for enlarging, two pointers 22, 23 are carried by carriage 21, and are independently adjustable by finger-operated screws 24 passing through slots in the bodies of the pointers. A second rack 27, fixed at one end to the lens board 7 and sliding in brackets 28 on the bed-plate 2a, engages a gear 29 by which a disc 31 is turned. This disc, with scale and pointers as described above, is mounted on a bracket on the copy-holder 8.

Abstract: 1,197,453. Unbalance computing. LOSENHAUSEN MASCHINENBAU A.G. 5 July, 1967 [20 July, 1966], No. 30895/67. Heading G4G. [Also in Divisions G1 and H3] In the dynamic balancing of a shaft in which the unbalance vibrations are measured electrically at two bearing planes, each A.C. signal V (Fig. 2) from the vibration transducers is converted into two D.C. signals representing the unbalance components Vx, Vy along two perpendicular axes. These signals are then converted into components along axes e 1 , e 2 , each inclined at an angle p to the y axis, the axes e 1 , e 2  being parallel to two planes containing eight compensation positions along the shaft. As shown (Fig. 10), the two signals Vx, Vy obtained by phase-rectification of the A.C. signal V are fed to inputs 1001, 1002 and a part of each, representative of Vx ¢ cosec p and Vy ¢ sec p tapped off by ganged switches 1004, 1005, set in accordance with the value of p. The latter signal is fed to a D.C. splitter 1006 which provides out puts of opposite polarity which are added to the former signal to provide outputs at 1008 and 1009 representative of Vx ¢ cosec p + Vy ¢ sec p and Vx ¢ cosec p - Vy ¢ sec p which represents the components of unbalance A 1  and A 2  along the axes e 1 , e 2 . The corresponding unbalance in two of four compensation planes along either the e 1  or e 2  axis is computed in the circuit of Fig. 4 in which the setting on potentiometers 403-406 and resistors 409-411 represent the distances a, b, e, d, e between the bearing planes and compensating planes. As shown, for determining the unbalance components in the two outer compensating planes 101, 104 (Fig. 1, not shown) at locations 105, 111, voltages corresponding to aA 1  and eA<SP>1</SP> 1  are tapped off from inputs A 1 , A<SP>1</SP> 1  at 401, 402 and added together by resistors 407, 408, then divided by amount equivalent to (b+c+d) by resistors 409-411, and added to the inputs. The output signals at 415, 416 correspond to representing the unbalance components at locations 105, 111.

Roller-and-ring mills. - Relates to grinding- mills in which a plurality of rolls on shafts depending from a carrier mounted on a vertical shaft act centrifugally against a grinding ring, and consists in means whereby the vertical shaft is driven through gears from an horizontal shaft, the mechanism being readily assembled and dismantled. The frame of the mill comprises pairs of A-shaped standards 2 and braces 3, carrying at the upper ends saddles 4 with concave sockets 5 receiving the turned end sections 6, 7 of a crossgirder 8. The girder is secured by bolts 9 passing through the saddles and has an enlarged central portion 10 through which the central rollnctuating shaft passes. Bearing recesses 14, 15 for the driving-shaft 18 are provided in the girder, a supplementary bearing 20 being provided for the free end of the shaft. Bevel gears 22, 23 transmit the drive to the central shaft, a thrust bearing 27 neutralizing the horizontal component of the action of the gears. Oil wells 25, 26 contain oil for lubricating the gears, a return duct 26<x> returning the surplus from the well 26 to the well 25, which acts as a reservoir. An extension 28 of the vertical gear projects into the aperture 13 and is secured to the rollactuating shaft by a split nut 29 and a supporting member 30. A cup-shaped member 31 on the girder 8 carries an aligning washer 33 and the lower race 34 of a ball bearing. The upper race 35 is carried by the part 24 within a wall 36. The extension 28 projects below the girder and carries a cellar 39 which prevents the gear from riding up when operated under heavy power. An oil receptacle 41, on the lower face of the girder, has a wall which projects upwardly into a recess adjacent the shaft. The recess has an outwardly flaring wall 43 so that, on rotation, oil is forced by centrifugal action into ducts 44 leading to spiral grooves 45 on the part 28. Oil is thus delivered to the bearing 34, 35, and returns through a duct 45<1>.
