Title: Keyboards
Inventor: BERNIN V M
IPC: H04L13/16
Filed: 1972-05-17
Abstract: 1380282 Keyboards ILLINOIS TOOL WORKS Inc 17 May 1972 [19 May 1971] 23251/72 Heading G4H A keyboard has a matrix of actuable devices which are scanned cyclically to produce an output which is stored and compared with the output one scan cycle later to detect changes. A clock-driven counter 20 drives the column lines of a keyboard matrix 10 in turn, a common drive-return line 50 being provided for noisecancellation. As each column is driven, row sense lines are scanned in turn by a multiplexer 18 controlled by the counter 20. A magnetic core 26 is provided at each of these row-column intersections, and depression of a corresponding key moves two magnets to desaturate the core and produce coupling of a drive pulse to the sense line. A further sense line, threading no cores, provides a common mode signal from which the multiplexer output is subtracted at 54 prior to summing 57 with a feedback signal from the shift register output (see below) for noise reduction. The summer output is thresholded, 58, and stretched, 60, to provide a strobe pulse via a pulse generator, 67, and gate 68, the signal also entering a shift register 70 to provide a one-scan-cycle delay, the shift register output being used to inhibit the gate 68 via an inverter 76 to prevent repeated outputs. The counter 20 provides a coded output to accompany the strobe signal, the coded output being recoded if necessary for case shift or control mode in a translator 100. A parity bit is generated at 110. Key positions corresponding to functions are recognized by decoders 88 responsive to the. counter 20 to inhibit the strobe signal at gate 68 and set respective flip-flops 84 if enabled by the output of inverter 76.

Title: Improvements in or relating to motor vehicles
IPC: B60G5/053
Filed: 1927-09-05
Abstract: 286,554. Utz, J. G. Sept. 5, 1927. Springs, arrangement of; axle attachments; equalizing load on wheels.-In a spring suspension for a motor vehicle, the springs are connected to an axle in such a manner that variation of the load on the springs at each side of the vehicle when it is travelling in a curved path causes the axle to move angularly in a horizontal plane to facilitate steering. The torque reaction is preferably transmitted through the springs alone. The invention is particularly described in connection with the rear dead axle of a sixwheeled vehicle, but may be applied to other axles or may be used to fit an additional axle to a four-wheeled vehicle. As shown, the driving axle 11 and rear dead axle 22 are connected at each side of the vehicle by a spring 18 pivotally mounted on a cross-shaft 16 on the frame 14. The connections of each spring 18 to the axle 22 comprise a bracket 28 mounted on the axle and carrying a yoke 33 which swivels on a vertical pivot and carries a pin 38 engaging the eye of the spring 18. An abutment 39 on the bracket is adapted to bear against the underside of the spring which passes through a strap 40 connected to the bracket and having its side members spaced from the sides of the spring to provide lateral play for the spring. The bracket at one side of the vehicle is free to rotate on the axle, the bracket on the other side being fixed to the axle by a screw 51. The abutment 39, spring eye 37 and axle 22 are normally located as shown in Fig. 7. When the vehicle takes a curve, the load on the outside and inside springs is increased and decreased respectively, and the axle and its connections take up the positions shown in Figs. 8 and 9 respectively so that the axle is moved angularly in the horizontal plane.

Abstract: 324,004. Johnson, J. Y., and Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Aug. 14, 1928. Caoutchouc, synthetic.-The polymerization of diolefines is effected with the addition of a diluent non-reactive, hydrocarbon. The polymerization is effected by means of sodium, or according to the first Provisional Specification it may be effected by heat, or the diolefine may be emulsified with an aqueous liquid and polymerized in presence of proteins by means of enzymes or oxidizing agents such as hydrogen peroxide. The diluent hydrocarbon may have a boiling-point similar to the diolefine or below or above it, and may even be of high boiling-point up to about 250‹ C. though these last would usually be employed in small quantities. The boiling-point of the diluent is advantageously so low that it can be removed after the polymerization by distillation with or without a vacuum at moderate temperature. In the examples butadiene is mixed with cyclohexane, petroleum, ether, benzene, butylene and amylene respectively, and polymerized by sodium.
