IPC: B65B41/08
Filed: 1955-03-30
Abstract: 777,168. Feeding wrappers. ROSE BROS. (GAINSBOROUGH), Ltd. March 29, 1956 [March 30, 1955], No. 9222/55. Class 94(1). A web 11 of wrapping material is fed along a cutting platform 12 by rollers 13, 14, the edge of the platform forming a stationary knife with which a movable knife 16 co-operates to sever successive lengths from the web to form a succession of wrappers 17. Each wrapper falls on to a platform 18 along which it is carried by a pusher 19 on a conveyer chain 21, the pusher positioning the wrapper on a continuation 22 of the platform 18 below a former 23 against which it is pressed by a reciprocating pusher 24 preparatory to being folded in known manner. The platform 18 is divided for the passage of the pushers 19, each of which is forked to provide two laterally-spaced pushing elements 25. The central portion 26 of the platform is pivoted at 27 and provided with an extension 28 carrying a roller 29 engaging a cam 31 which operates in timed relationship with the knife 16 to cause the rear end of the portion 26 to tilt to about the level of the platform 12 to receive and support the wrapper 17 prior to its severance from the web. The sloping surface of the portion 26 allows the wrapper to slide smoothly without buckling so that as the portion 26 is lowered, the wrapper is properly positioned on the platform 18 for engagement by the pushing elements 25.

Filed: 1939-03-24
Abstract: 526,824. Magnetic clutch relays. DELL, R., EVERY, W. S., and LONDON PASSENGER TRANSPORT BOARD. March 24, 1939, No. 9261. [Class 38 (v)] In a time-element electric relay simultaneous supply of current to a self-starting electric motor 3 and electromagnetic clutch 8 causes the rotation of gear wheels 4, 5, 6 and the attraction of an armature 10 having a rack 11 which is thus brought into engagement with the wheel 6. The armature and rack, which are pivotally supported at 20 to an arm 19 pivoted at 21, move upwards, till after a time interval, an adjustable nut 15 on an extension of the armature engages an arm 37 thereby tilting a shaft 26 and operating contacts 28. When the relay is de-energized, the armature 10 moves away from the pole 7 of the magnet 8 under the action of a counterweight 18 thereby becoming declutched and then descends to its original position. The foot 48 of the armature may also act on a lever 45 coupled by a link 44 to a " proving " contact 40.

Filed: 1970-02-26
Abstract: 1,242,373. Building tyre breakers. NATIONAL-STANDARD CO. 26 Feb., 1970 [10 March, 1969], No. 9390/70. Heading B7C. A tyre breaker winding machine comprises a building drum 20 mounted on a hub 88, two pinwheels 34, 36 mounted on a shaft 50, each pinwheel having a diameter less than that of the drum 20 and one or more pins 38, 40 extending radially therefrom and a pivoted traverse arm 24 with one free end 52 which is reciprocally moved across the radially outer circumferential surface 21 of the drum carrying a thread guiding device 22 to lay one continuous thread 18 in a zig-zag form on a sheet 28 of uncured rubber carried on the drum surface 21 to form a breaker 32, the shaft 50 and hub 88 being positioned with respect to each other such that during rotation at least one of the pins projects beyond the drum surface 21 over an arcuate length of the drum's circumference in the region where the free end 52 of the arm 24 reciprocates, the rotational speeds of the drum and pinwheels being such that at the end of each traverse of the free end 52 there is a pin positioned to be engaged by thread. The thread 18 may comprise a metal wire covered in uncured rubber or plastics. The velocities of the drum and pinwheels are adjusted with respect to each other and with regard to the number of pins on the pin wheels so that each line of thread laid during a revolution of the drum is incrementally and evenly spaced from the line laid during the previous revolution. The drive mechanism 26 for the arm 24 comprises a roller bearing 56 that rides in a heart-shaped slot 58 of an eccentrically driven cam 60, the slot having two constant velocity segments 62 interconnected by two acceleration segments 64. The segments 62 lay the cord in straight lines between successively engaged pins and the segments 64 provide a rapid change of direction at the angles of the zig-zag to avoid large radii loops at the edges of the breaker 32 formed by the thread. When it is desired to stitch the completed thread breaker 32 to hold it together, the peripheral velocities of the drum and pin wheels are adjusted to a common value so that the pins 38, 40 hold the thread 18 on the drum 20 in position while it is stitched by a roller assembly. The drum 20 is collapsible and removable from the hub 88 to enable the breaker 32 to be removed.

Title: Improvements relating to photoelectric scanning of recorded data
IPC: H01Q1/10
Filed: 1954-03-31
Abstract: 763,104. Photo-electric record sensing. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 31, 1954 [April 1, 1953; April 24, 1953], No. 9424/54. Class 40 (3). In photo-electric apparatus for scanning characters on a record the character or character carrier is of the colour of maximum or minimum responsiveness of the cell or vice versa. In the embodiment of the invention shown in Fig. 2 the photo-electric detector F is of cadmium sulphide and may have an amplifier associated with it. Cadmium sulphide is highly sensitive to green light and the record K is green light of a wavelength of 5200. The characters on the card are of black ink although they may be red. A green filter is provided in front of the light source for filtering out blue and red. The Specification mentions the use of a zinc sulphide cell with light of 4360. In a modification (Fig. 3, not shown), green light is transmitted through apertures in a card to a green-sensitive photo-cell, the card being particularly greenabsorbing. Red light may be directed through to a lead sulphide cell. In the arrangement shown in Fig. 4 use is made of the fact that red light acts to repress the effect of green light. In this case red light 8 is diffusely reflected from the record card 1 and received on the cadmium sulphide photo-cell 7. When an aperture is aligned with a hole in a diaphragm 2 however green light 5 impinges on the photo-cell while the red light passes right through and is unreflected. This is said to improve the contrast of the photo-cell outputs.
