Title: Device for production of uniform circle graduations
Inventor: BAUERSFELD WALTHER
IPC: B44B3/02
Filed: 1951-05-31
Abstract: 696,102. Dividing-engines. ZEISS-OPTON OPTISCHE WERKE OBERKOCHEN GES. May 31, 1951, No. 12827/51. Class 97 (iii). An apparatus for producing uniform circle graduations comprises a mounting body d having a ruling mechanism o<SP>1</SP> fitted thereto, and two coaxial graduation discs e, k, arranged thereon, one of the graduation discs k being rigid with a disc m to be graduated and the other graduation disc e being connected to the ruling mechanism, at least one of the graduation discs being provided at its periphery with a number of equally spaced springy elements and the other graduation disc being provided with corresponding elements for engaging with the springy elements and means for bringing the elements into and out of engagement. The disc k has a recess k<SP>1</SP> which receives an accurately wound coil-spring l secured by clamping plates l<SP>1</SP>. The disc e provided with accurately-spaced pins e<SP>2</SP> has a cylindrical portion e<SP>1</SP> projecting downwardly over a guide box d<SP>1</SP> rigid with the baseplate c on which the body d is mounted and is connected by membrane discs d<SP>4</SP>, d<SP>5</SP> to body d to permit limited axial movement. To rule a graduation line on disc m, which is clamped by ring m<SP>1</SP> to disc k, the guide carriage o<SP>2</SP> carrying graver o<SP>1</SP>, is slid along a bridge o which is screwed to the rim d<SP>6</SP> of the mounting body d. By means of a crank (not shown) a shaft h<SP>1</SP> rotatably mounted on the base-plate c by bearings h<SP>2</SP> is then rotated 180 degrees whereupon through an eccentric h on the shaft h<SP>1</SP>, connect. ing bar f, and pivot pin g, a cylinder d2 is moved downwardly within the guide box d<SP>1</SP>. The disc e, which rests on a steel ball d<SP>3</SP> carried by cylinder d<SP>2</SP>, is thus allowed to move downwardly to disengage its pins e<SP>2</SP> from the coil-spring l. By means of a crank, carrying, eccentrically to the crank axis, a pawl which is spring-pressed into engagement with teeth k<SP>2</SP> on the disc k, the latter is rotated through one tooth spacing and on rotating the shaft h<SP>1</SP> through a further 180 degrees the pins e<SP>2</SP> re-engage between the coils of spring l. Due to the resiliency of the coil and the freedom of disc k which is mounted on the body d by a ball-bearing i, the disc k assumes a position in which the errors in the spacing of the pins e<SP>2</SP> and the coils of the spring l, are averaged out. Another graduation line is then drawn and the process repeated. In a modification the springy elements are provided by steel needles which are slightly pointed at their upper ends and are carried by the disc e. They engage between balls which are located in notches in the disc k and are carried by a cage ring. In a further modification one graduation disc is formed as a worm-wheel which coacts with a plurality of worms uniformly distributed over the circumference of the second disc and so mounted that they are held in their axial directions by springy members.

Title: A process for the production of rubberised fabric provided with a fibre coating
IPC: B29C37/00
Filed: 1931-05-04
Abstract: In the preparation of fibre-coated rubber surfaces, the loose fibres are attached by a solution or a dispersion of a sticky decomposition product of rubber or a rubber-like substance, such as guttapercha or balata, with or without undecomposed rubber and the usual compounding ingredients.  Prior to vulcanization, the coated surface may be passed under a smoothing roller heated to 50-60 DEG  C.  A suitable binding-agent may be prepared by heating rubber for several hours at about 1000 DEG  C. with a small amount of mercaptobenzothiazole. Dispersions of the decomposition product in aqueous or organic media or mixtures of these may be employed. In an example, the cement employed consists of 30 parts of the decomposition product referred to above dissolved in 70 parts of benzene.  Natural or artificial aqueous dispersions of rubber may be used instead of the corresponding organosol or mixtures of these may be employed and, in the case of a rubber coated fabric, this may be coated with rubber on both sides, the fibres being attached to one or both layers.
