Title: Making Crossed-end Bags
IPC: B31B160/20
Filed: 1967-07-28
Abstract: 1,193,676. Block-bottomed bags. WINDMÍLLER & HÍLSCHER. 28 July, 1967 [3 Aug., 1966], No. 34869/67. Heading B8K. [Also in Division B5] A tube blank I (Fig. 1) for a crossed-bottom bag secured by a dry pressure-sensitive adhesive which sticks only to itself, is cut at the ends to expose parts of the inside surfaces of the end flaps to receive the adhesive. In the blank illustrated the lower wall is extended at 3, and the upper wall at 11, while the opposed walls at each end are correspondingly recessed. An adhesive with a volatile solvent is then applied at the hatched areas on both sides of the blank and is allowed to dry before the blanks are stacked. The blank ends are subse quently opened to diamond form, as shown in Fig. 3, a valve sleeve 18, coated with the same adhesive, is secured in place, and the bottoms closed in the usual way. This results in the outer exposed surfaces having a coating of adhesive which can either receive a cover sheet or which may be inactivated, for example by talcum powder or by a solution of water and alcohol with a wetting agent. Alternatively, the adhesive may be printed in a pattern which leaves the exposed surfaces of the bottom free. A suitable adhesive for polyolefin sheeting is a mixture of isocyanate modified polyesters with free hydroxyl groups and isocyanate resins in a solvent. The sheeting may be first subjected to a corona discharge. The transverse cuts by which the bag blank is separated from a web are preferably first formed as perforations, those parts 9, 10 (Fig. I) which coincide in the two walls being subsequently cut while the non-coincident perforations 11, 12 are pulled apart by accelerating rollers. Where the blanks are cut from extruded lie-flat tubing, the perforations are made by apparatus including a carriage floating inside an opened portion of the tubing. Where the blank is cut from tubed flat web, the perforations may be made before the web is tubed. The seam in the tubed web may be by a heatactivated adhesive. The web may be multi-ply.

Title: Actuating device for the front brakes of automobiles and other applications
IPC: B60T11/04
Filed: 1922-12-22
Abstract: 204,298. Soc. Anon. des Anciens Etablissements Hotchkiss et Cie. Sept. 23, 1922, [Convention date]. Controlling - apparatus, arrangements of hand, foot, and transmission gear in conjunction with; flexible transmitters. - Relates to means for compensating for the effect of the relative movements of parts connected together by a leafspring, upon mechanisms mounted upon the parts and operatively connected together. The invention consists in utilizing the movement of the free end of the spring for effecting the compensating action. The application to brake-mechanism for the front wheels of automobiles is described. A brake actuating arm 0, Fig. 1, pivoted at O<1> upon the axle N, is connected to the pedal A, mounted on the chassis, by a cable H which passes over pulleys K, J, and G, mounted respectively upon the spring shackle L, upon the chassis, and upon a lever F keyed to a shaft E. This shaft is hollow, and the cable H extends through it to the brake on the other side of the vehicle so as to provide an equalizing device. The shaft E carries an arm D connected to the pedal A by the parts B, C. When the spring M yields, the arm O being carried by the axle N moves to the right and tends to slacken the cable H, but this slackening tendency is compensated for by the tautening action of the pulley K, which moves to the right a distance substantially double that of the arm O. The tension of the cable is thus unaffected by the movement of the axle N. In Fig. 3, the arm O is connected by a rod H<2> to a lever K pivoted at L<1> to the shackle L and the end c of this lever is connected by a rod H<1> to the arm F on the cross-shaft E. Assuming the axle N to be fixed at the middle point of the spring M, the pivot point b of the link H<2> on the lever K is disposed at the middle point of that lever. The horizontal movement of the point L<1> when the spring yields will thus be double that of the point band as the lever arms L<1> c and L' b are in the same ratio the point c remains stationary. The braking action is thus unaffected by movements of the axle N.
