Abstract: 1,075,534. Typewriters. OPTIMA BUEROMASCHINENWERK ERFURT VEB. July 6, 1964, No. 27707/64. Heading B6F. A paper feed mechanism for a typewriter comprises a feed lever 1 pivotally mounted on a pin 2 and connected through an intermediate lever 3 to a toothed segment lever 5 pivotally mounted on a pivotable lever 4, said segment lever 5 being pivotable into an engagement with a platen pinion 6 for rotation of the latter. To rotate the platen the feed lever 1 is pivoted anticlockwise whereby the intermediate lever 3 displaces the toothed lever 5 so that a toothed portion 5a engages the pinion 6, the displacement being arrested by a stop pin 10a engaging the pivotable lever 4, which pin is set to allow a pivot pin 4a to coincide axially with the pin 2. Pivoting of the lever 4 also causes rotation of a spindle 9 fast with the lever 4 to disengage the locking members of a line spacer lock (not shown) thus allowing the platen, to rotate freely. Further movement of the feed lever 1 rotates the platen pinion 6 through the intermediary of the lever 5 until an edge 5e of the lever engages an adjustable stop 14. During the initial return movement of the feed lever 1 a spring 12 returns the lever 4 back into contact with a stop 10b whereby the line spacer lock is again locked and the toothed lever 5 is disengaged from the platen pinion 6.

Filed: 1926-11-08
Abstract: 272,382. Ingersoll-Rand Co., (Assignees of Metzgar, C, W.). July 15, 1926, [Convention date]. Regulating compression.-In a compressor comprising cylinders A, B and an intercooler C and means for unloading the intercooler, means are provided for automatically unloading the cylinder B when the intercooler is unloaded. The intercooler may be unloaded by a valve 5 opening to an atmospheric port V operated by a piston e supplied with pressure fluid by a pipe 5 connected to a casing Y which communicates with the usual clearance regulator X. When the valve S opens, pressure falls in the intercooler, and this fall is communicated through pipes 21, t to the undersides of piston o, which normally hold release valves a in closed position. The pistons are forced down by springe s, allowing valves a to open and unload the cylinder B. A switch p on the switchboard of the motor G driving the compressors controls a solenoid q, the armature z of which controls inlet and release valves 6, 7 of a device Z controlling the main regulator X. When the switch p is open, the armature z operates the valves 6, 7 so that a rod u lifts the lever R, thereby operating the regulator X. Specification 260,942 is referred to.

Title: Method of producing one or more integrated semiconductor circuits
IPC: H01L21/00
Filed: 1969-06-04
Abstract: 1,255,421. Integrated circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 4 June, 1969 [4 June, 1968], No. 28300/69. Heading H1K. In the production of a large-scale integrated circuit comprising a number of interconnected basic circuits, either identical or of various types, in a common semi-conductor wafer, each circuit is tested and the results are stored as a test record. A single mask for defining the electrical connections required between the usable basic circuits, omitting the circuits which have been found to be inoperative, is then assembled from a number of different component masks using the test results. In the arrangement shown a wafer contains a number of trigger stages 27-33, Fig. 6, to be used in a shift register. Only circuits 27, 28, 30 and 33 are found to be usable, so a connector-defining mask is assembled by a step-and-repeat photographic process involving two component masks (Figs. 4 and 5) one of which provides for connections to usable basic circuits while the other provides by-pass conductors for inoperative basic circuits. A computer may be used to store the test results and to determine the stages in the mask production process. If the basic circuits lie in more than one row on the wafer, further different component masks are required to provide the necessary interconnections. The basic circuits may themselves differ from one another, again requiring different component masks. In order to assemble the complete mask a number of intermediate masks may be formed, each of which contains information relating to only one of the various component masks produced by a step-and-repeat process, the positions of the component mask images on the intermediate mask being determined by the test result. All the intermediate masks are then superimposed and the complete mask is obtained by photographing the assembled intermediate masks. The final mask is used in a photo-lacquer etching stage to define the desired interconnection pattern in a singlelayer or multi-layer metal film evaporated on to an oxide coating on the wafer. The basic circuits on the wafer may be selected so that different large-scale circuits can be produced depending upon which of the basic circuits are found to be usable. A computer is programmed to optimize the use of the operative basic circuits determined by the test report, so as to control photographic production of the overall connector-defining mask from the various component masks.
