IPC: B65H23/18
Filed: 1974-01-29
Abstract: 1455897 Web winding SAMCOE HOLDING CORP 29 Jan 1974 [5 April 1973] 4157/74 Heading B8R [Also in Division D1] After having been treated (see Division D1), a fabric 145 is wound into a roll by a roller 141 driven in synchronism with calendar rolls 86, 87, preferably, to maintain the fabric under very slight tension. Mandrel guiding channels 148, 149 are secured to a bracket 146, the channel 148 supporting a mandrel 151 on which the fabric 145 is being wound. When the desired roll size has been reached, a fluid actuator 152 pivots the bracket 146 counterclockwise of Fig. 1A so that the fabric roll rolls downhill until the mandrel ends drop into V-shaped troughs 153. An empty mandrel, held in the channel 149, rolls into the channel 148 and, when the bracket 146 is pivoted back to its normal position, rests on the roll 141 and a fresh roll is wound thereon. Immediately prior to doffing a roll, a foot switch 180 is actuated to stop or slow down the apparatus. A cut-off device severs the fabric after completion of the doffing of a roll. The filled mandrel may be automatically weighed when resting in the sockets 153 by a strain gauge or transducer element.

Title: An improved method and apparatus for balancing vehicle wheels
IPC: G01M1/28
Filed: 1960-02-05
Abstract: 888,792. Wheel balancing apparatus. HOFFMANN, D. Feb. 5, 1960, No. 4178/60. Class 106 (2). A device for determining, the out-of-balance of a wheel whilst retained on a vehicle comprises a transportable housing 1 containing a frictionwheel 10 driven by an electric motor and which wheel drives the jacked-up wheel of the vehicle. An electro-mechanical transducer 35 is secured to the vehicle suspension and triggers a stroboscope lamp 21 during oscillation of the suspension as the vehicle wheel is rotated. By rotating the wheel successively in each direction of rotation a mark on the wheel is seen to occupy two positions. The corresponding upper vertical position of the wheel can then be noted and the midpoint between these two latter points is thereby determined as the out-of-balance position of the wheel. A weight determined by the deflection of an amplitude-indicating instrument 17 can then be selected from a series of pigeon-holes and applied to the wheel. The housing supports a seat 13 covering a tool-box.

Title: An improved toy, advertising device or the like
IPC: G09F1/06
Filed: 1930-02-07
Abstract: 350,507. Scenic toys. SEGEAL, B., 23, Springfield, Clapton, London. Feb. 7, 1930, No. 419.5. [Class 132 (iii).] A toy or advertisement device comprises a c a r d folded to form a front and a back sheet enclosing an intermediate sheet a portion of which protrudes through a slit in the front sheet and can be made to reverse by movement of the intermediate sheet. As shown, the card or other material is folded to form a front sheet b, a back sheet a, and an intermediate sheet c and the latter two sheets are folded at e, f so that by turning the fold h into continuation of the sheet c the intermediate sheet slides and effects a change in the appearance of the front sheet. For this purpose a portion i, partially cut out from the intermediate sheet, is protruded through a slit k and thus exposes one side or the other according to the position of the intermediate sheet. Other changes may be brought about by arranging a finger n or a surface p on the intermediate sheet to co-operate with a slit m or opening o. As a further feature, a slip q may be inserted in slits in the front and intermediate sheets and be attached as at t to an eyelet connecting the front and back sheets. In a modification, the front and back sheets may be secured together at top and bottom and the intermediate sheet duplicated and inserted from the sides.

Title: Improvements relating to methods and means for folding in laundry operation
Inventor: EGGLETON OSWALD JAMES
IPC: D06F89/00
Filed: 1962-02-02
Abstract: 985,234. Folding fabrics. FINIMASTER FOLDERS Ltd. Oct. 29, 1962 [Feb. 2, 1962], No. 4221/62. Heading D1S. Apparatus for folding sheets into multiple folds comprises means for feeding the sheet to a winding mandrel at a linear speed in excess of the peripheral speed of the mandrel whereby the sheet is wrapped round the mandrel into spiral form, and means for ejecting the sheet from the mandrel in a direction approximately in the line of the axis of rotation of the mandrel. In the embodiment shown frame 10 carries driving unit 11 for driving a shaft 14 through suitable clutch means. Shaft 14 carries a freely rotatable hollow drum 20, a braking pad 16 being provided to act on the drum. The drum 20 has a V-notch or recess 21 running lengthwise of its surface into which the leading edge of a sheet S can be fed. Concentrically within the drum 20 there is a roller 25 fixed on shaft 14 and also having a V-notch 26 corresponding to the notch 21. The arrangement is such that the roller 25 can rotate inside the drum 20 across the notch 21 and thus trap the leading edge of sheet S. Feeding of the sheet is effected by conveyers 30 driven by belt means from shaft 14. The conveyer 30 carries the sheet forward and the leading edge lifts a floating roller 33 which operates a microswitch 34 and thence a solenoid valve unit 35 which in turn admits air to the face of piston 36 in cylinder 37. The piston rod passes a one-way trip device 38 and makes contact with micro-switch 40. During the time delay the leading edge has been fed into the notch 21. Operation of switch 40 energizes another solenoid valve unit 44 which in turn operates brake pad 16 and clutch means (not shown) to drive the inner roller 25. The V-notch in the roller nips the leading edge of sheet S and the drive continues, to wind the sheet round the drum. When the trailing edge of the sheet passes roller 33 the circuit is broken and the various operations are reversed. When the roller 25 comes to rest with the sheet wound thereon a further solenoid valve assembly 53 is operated which admits air to cylinder 54 (Fig. 4). This governs the means for withdrawing the wound up sheet from the drum. This means comprises an annular plate 57 which closely encircles drum 20 and is connected to piston 56 working in cylinder 54 such that when the latter is pressurized the plate 57 is forced along guide rods 58 so that it slides along the drum 20 and pushes the sheet off on to a table or conveyer where it collapses to a folded form.
