IPC: B23B49/02
Filed: 1969-12-16
Abstract: 1290893 Punch and die holders DAYTON PROGRESS CORP 16 Dec 1969 [16 Dec 1968] 61254/69 Heading B3W A tool holder comprises a body 10, Fig. 1, with a passage 15 for, e.g. a punch 24, and a plug 26 which is arranged, in use, to abut a die shoe 20 at one end and the tool head at the other to transmit force applied to the tool directly to the die shoe. A portion 27 of the plug 26 is a friction fit in the main section of the passage 15 and a frusto-conical portion 28 is in spaced relation to a frusto-conical section 16 of the passage 15. The punch 24 is detachably mounted in the passage 15 by engagement of a spring-biased ball 21 in a recess 25. A pin 31, locating the holder relative to the die shoe 20, forms a tight fit in a passage 29 through the plug and a slip fit in a passage 30 in the die shoe. In a holder 10<SP>1</SP> for a die 33 the pin 31 is replaced by an extension 38 of the plug 35. To mount holders 10 and 10<SP>1</SP> in alignment first a passage 39 is drilled in die shoe 32. The holder 10 with punch a plug assembled, is lowered to locate the tip of the punch in the die and aligned thus the holder 10 is clamped to the die shoe 20. With the punch removed the passage 30 is drilled, the drill passing through passages 15 and 29. Two further passages aligned with passages (17), Fig. 5 (not shown), in the holder 10 are drilled in the die shoe 20 to receive cap screws. The holder 10<SP>1</SP> is similarly screwed to the die shoe 32.

Abstract: 1296011 Machining commutators AMDEK CORP 1 Jan 1971 43/71 Headings B3B and B3K A method of machining a surface of a rotatable workpiece having electrically conductive and non-conductive zones on said surface, e.g. a commutator 25 of an armature 21, or on a template connected to the workpiece, comprises demountably securing the workpiece for rotation in V-bearings 23, 24 by a load applied by a flexable belt which also frictionally rotates the workpiece in the bearings; electrically probing the surface to be machined, or the surface of the template, whilst it is rotated to detect a boundary between a conductive and non-conductive zone; arresting the rotation of the workpiece by stopping the belt when a boundary is detected; performing a first machining operation; and then either, repeating the previous steps to perform subsequent machining operations; or, performing subsequent machining operation at predetermined locations on the said surface when the belt stops the drive to the workpiece. Apparatus for performing the method comprises a rotary cutter driven by a motor 33 and movable relative to the armature by a carriage 34; yieldable indexing means for indexing the armature comprising a stepping motor and pulleys 37, 38, 39 for the belt; and control means. The control means includes a radio frequency probe switch 47 having a single point probe riding in intimate contact with the commutator surface to sense each successive insulative slot and to halt the rotaty indexing of the armature for an undercutting operation, and to signal said indexing means to recommence rotation of the armature after completion of an undercutting operation. The V bearings and the yieldable drive permit the armature to move slightly under the influence of the rotary cutter to allow a slightly askew slot to be cut. The armature is freely mounted in the V bearings without any clamps &c., and a lower run of the belt 37 engages the surface of the armature to yieldingly index it in minute, discrete increments. In machining a new commutator the blank has a template mounted on its end that includes the electrically conductive and non-conductive zones (Fig. 4, not shown).

Title: Process for bending glass
IPC: C03C15/02
Filed: 1970-01-19
Abstract: 1309333 Bending sheet glass GLAVERBEL 18 Jan 1971 [19 Jan 1970] 2445/70 Heading C1M A process for bending a sheet of glass comprises the steps of subjecting the sheet to a surface treatment in which the surface is renewed and as a result removes surface flows at least on the surface which will be convex after bending: and subjecting the sheet to bending forces while the viscosity of the glass is above 10<SP>10</SP> poises, preferably 10<SP>13</SP> poises. The treatment may be fire polishing, mechanical polishing or an etching treatment using a gaseous or liquid medium. The etching medium may be a fluorine-containing medium such as hydrofluoric acid, preferably in combination with sulphuric acid. Such an acid etching medium should have a pH of less than 4. Alternatively the etching medium may be one containing OH ions such as a sodium hydroxide solution. The process may be carried out by supporting a glass sheet 7 from a trolley 2 running on a monorail track, immersing the sheet 7 in an etching medium bath 8 contained in a tank 9, and after a suitable period removing the sheet from the bath, and laying it flat on a die 11 which runs on rails 13. The die can then be pushed into a furnace 14 where the end edges of the sheet are pressed down by elements 29 mounted through rockable trunnions 30 on two bars 25 which may be lowered gradually to accomplish the bending of the glass sheet. The glass and treatment medium may be given relative oscillatory movement of sonic or ultrasonic frequency. The use of relatively low temperatures enables such materials as austenitic steel which includes in percentage by weight Co 18; Ni 8; C 0À02 to be used to make the dies. The following glass compositions in percentage by weight are disclosed:- The glass sheet may be strengthened by chemical tempering after bending, such as by ion exchange.
