Title: Apparatus for producing on the image screen of a display unit a visual diagrammatic representation of the variation as a function of time of a series of measured values present in digital form
IPC: G01R13/28
Filed: 1969-08-29
Abstract: 1283706 CRT display systems SIEMENS AG 29 Aug 1969 [29 Aug 1968] 43231/69 Heading H4T [Also in Division G4] Apparatus for producing on a screen of a display unit 1 (Fig. 1) as a function of time a series of measured values in digital form includes a store 4 from which the digital values are cyclically fed via a digital/analogue converter to the display unit. When a new measured value arrives the oldest measured value is erased, the new data being stored in its place. The stored values are preferably sequentially fed to preset a counter 3 which as the electron beam is horizontally deflected under the control of clock pulses is counted down to zero at which time the beam is unblanked. Alternatively, the digital values may be converted to an analogue voltage which is compared with the sawtooth horizontal deflection voltage, at equality the beam being unblanked. Bar diagrams may be obtained by unblanking the beam for the rest of its horizontal scan. The store may be a disc, drum or delay line. In the delay line store of Fig. 3 (not shown), circulating data is read into the store (20) via a gate (G2). When new data is to be read in an address signal is stored in a register (13) and at equality between the register and a counter (17) an output pulse lasting for one word length enables a gate (G1). Preferably, the address register holds the address N - W + 1 where N is the bit capacity of the store and W the word length of the measured value so that after reading of the new data the address counter is at its full count after which it is reset to W so that the addresses of the stored data are switched by one word length. A number of delay line stores may be operated in parallel each store being associated with a preset counter, the outputs from which have different amplitudes so that a number of different brightness may be simultaneously displayed on the screen. Alternatively, the screen may be divided into two upper and two lower quadrants. The data to be displayed in the upper quadrants is first read out to the preset counter, but phase shifted so that the counter is first preset by the data for one quadrant and counted down to control the beam and is then preset by the data for the second quadrant and again counted down to control the beam. The process is then repeated for the lower two quadrants. Measurements may be displayed in colour and scale markings may be indicated on the edge of the screen. The brightness of the display may be made to vary periodically.

[Also in Division B3] A sprag-type clutch for a press driven from an electric motor has an output shaft 106 which can be locked against rotation when the clutch is disengaged. The motor drives a pulley 170 keyed to the clutch input member 174 which is rotatably mounted by ball bearings 176 in the housing 178. The input member has a cylindrical recess into which the end 188 of the output shaft extends. The end 188 has an octagonal cross-section with flats 190. An annular cage 204 is positioned around the end 188 and has fingers 202 which extend between the end and the input member. Eight rollers 206 are provided between the fingers and the cage is spring biased (208), Fig. 8 (not shown), to trap the rollers between the end and the input member to lock them together. The clutch is disengaged by pawls 228, 230 on a pair of arms 214 which are pivoted to engage with recesses on the cage and on the output shaft end to lock them together with the rollers 206 at the midpoints of the flats. The arms are spring biased towards the housing and pivoted away from the housing by a solenoid actuated pin (224), Fig. 5 (not shown). The solenoid is de-energized when the ram actuates a limit switch as it descends so that the clutch engages. After the workpiece turntable has rotated through the required angle a second limit switch is acuated to energize the solenoid and disengage the clutch. The clutch can be held disengaged by a pin 217 which is spring biased out of the housing. A rotary valve 112 is driven by the output shaft of the clutch to supply hydraulic fluid to either side of the cylinders of the tools of the press and to the cylinder which reciprocates the ram. The valve spool receives pressure through a port 280 to a peripheral recess 282. The recess communicates with further part peripheral recesses 286, 302. The remaining peripheral parts are occupied by further recesses 288, 304 which are connected to the fluid sump for all angular positions of the spool. During part of the rotation the land 286 is connected to one end of the tool cylinders through a port 298 and during the other part of the rotation the cylinders are connected to the sump. The other recesses 302, 304 are similarly connected to the other end of the cylinder to act complementary to the recess 286, 288. A pair of part annular recesses 316, 318 are provided at the spool ends connected to the inlet port 280 to maintain a state of rotational balance. A safety gate (130), Fig. 3 (not shown), is provided at the opening of the press with a roller (144) so that when the gate is manually raised or lowered the roller pivots an arm (138) to move a stop (152), Fig. 4 (not shown), into or out of engagement with the tool head (46) to prevent the lowering of the head while the gate is raised.
