Patent GB-640724-A (GB)
Title: Thin sheets, films and the like of organic plastic material and process of obtainingthem
IPC: B29C48/13
Filed: 1947-07-14
Abstract: In the production of a sheet or film, small projections, preferably several parallel narrow ridges, are formed near the edges of one side, and corresponding depressions are formed on the other side directly opposite the projections p  <PICT:0640724/IV (a)/1> <PICT:0640724/IV (a)/2> <PICT:0640724/IV (a)/3> <PICT:0640724/IV (a)/4> so that when the film is wound up on a reel the central portions of the film in the various convolutions do not press or drag against adjacent central portions, and relative axial slippage is prevented.  Smooth winding of the film is thus promoted with avoidance of pressure marks or beads which in turn would lead to the formation of streaks in any light-sensitive emulsion which may subsequently be coated on the film.  The film may be produced by casting a solution upon a forming surface which is provided at the edges with depressions so as to produce corresponding projections in the film.  The depressions may be in the form of longitudinal grooves so as to produce longitudinal ridges in the edge portions of the film.  As shown in Fig. 2, the casting surface 14, formed on a backing 13, is provided with shallow grooves 15 near its edges.  The grooves may be continuous or broken but it is preferred to have four grooves at each side, spaced about 5/16 of an inch apart.  The cast film has corresponding ridges 11 (Figs. 1 and 3).  During the setting and drying of the film depressions 12 are formed on the opposite side from that of the ridges, but these are shallower than the thickness of the projections on the other side.  When the film is wound in layers on a reel or core, as shown in Fig. 4, the parallel ridges hold successive layers slightly apart so that the central portions are not in tight frictional contact with each other.  Interlocking of the projections and recesses prevents axial displacement of the windings.  When the film is coated with a light-sensitive emulsion, it is preferable to extend the coating over some or all of the ridged part so that ridges will still be present in the coated film as shown at 20 (Fig. 1).  Specification 279,047, [Class 2 (ii)], is referred to.

Filed: 1924-08-06
Abstract: 234,672. Marks, E. C. R., (Elliott-Fisher Co.). Aug. 6, 1924. Adding - apparatus; clear signals and marks. -In computing machines and more particularly those combined with a typewriter a clear signal printing mechanism controlled by a separate key is provided and is so constructed that no strain will be sustained by the totalizing-counter or other sensitive part of the mechanism by a misoperation of the said key, i.e. when the numeral wheels are not displaying zeros. As shown applied to an Elliott-Fisher book-keeping machine the numeral key levers as well as the " clear " key lever 5 are mounted on a rod 6 and each lever is connected through the usual links and levers to a corresponding type lever. The lever 5 has pivotally connected thereto, at 29, a bracket 28 having at its upper end an eccentric bearing for a link 27 that is attached at its other end to a link 23 pivotally mounted on a standard 25 secured to the framework. Movement of the bracket 28 in one. direction is prevented by an adjustable stop 30 and in the other direction is yieldingly opposed by a spring 31. The link 23, Fig. 7, is formed with guide surfaces 33 for a depending projection 32 on the key lever 5 and has a pin 22 engaging the bifurcated end of an arm 19 secured to a spindle 18. The spindle 18 passes through the casing of the totalizer and has secured thereto a bail member 17 that coacts with discs 15 at the side of the numeral wheels 12. The discs 15 fill the inter-tooth spaces except between the numerals " 7," " 8 " as shown in Fig. 4. When this space is presented to the Lail 17 the " zeros " appear at the sight aperture 13, so that if the " clear " key is depressed the bail can enter the space and rock the arm 19 so as to remove the pin out of the path of the projection 32 on the key lever. If the totalizer is not in the "clear position and an attempt is made to depress the " clear " key its movement will be arrested by the projection 32 engaging the pin 22 and the bracket 28 will be rocked against the action of the spring 31.
