A low cost autographic register which, after a pack of forms such as continuous fan-folded forms therein has been used up, may be discarded, comprises three parts namely (1) a tray-like casing 31, Fig. 2, to receive the pack 40, (2) a cover 71 detachably mounted on the casing and having a writing opening 77, Fig. 1, and (3) a writing platen 88, Fig. 4, detachably supported in the register, a tongue 95 carrying form-aligning pins 98, 99 being integral with but resiliently movable with respect to the platen 88. Slots 96, Fig. 4, separate the tongue 95 from the platen 88 to allow of the resilient movement. The pins 98, 99 are engaged with perforations 48, 49, Fig. 1, in the forms adjacent to the leading edges of the forms, and pass into holes 78, 79 in a horizontal strip 76 forming part of the cover 71. A depressed part 100 of the tongue 95 and a cut-away part 80 of the strip 76 allow of the insertion of the fingers to depress the tongue and release the pins 98, 99, and to grip the leading edge of a form for bringing a fresh form length into writing position. A tearing edge 81 is provided on the strip 76. Inwardly-projecting flanges 57 ... 62 on the inside walls of the casing 31 serve to support the platen 88 and also to align the pack 40. Latch holes 84, 85, Fig. 1, in the cover may be engaged by latching tongues 86 on the casing. The rearmost end of the platen 88 is bent downwardly at 90, Fig. 2, and provided with a beaded edge 91 around which the forms pass. The forms of the pack may include interleaved carbon sheets or may have coatings of transfer material, but separate carbon paper attached to a bar 92, Fig. 4, inserted in eye elements 93, 94 on the casing may be used. A slot 66 is provided in the base of the casing for the insertion of used forms beneath the pack 40, and a keyhole slot 67 in the base may be used for suspending the register on a nail. In a modified construction (Figs. 6-8, not shown), the casing part has a transverse flange and also angle pieces at the leading corners to support the writing platen, and the cover has no holes to receive the aligning pins. The parts are moulded from a plastics material such as styrene.

Title: Pulse decoding circuits
IPC: H03K5/159
Filed: 1955-06-13
Abstract: 774,459. Pulse discriminating circuits. COLLINS RADIO CO. June 13, 1955 [Oct. 26, 1954], No. 16963/55. Class 40(6) A circuit for producing an output .pulse only when a pair of pulses having a predetermined time spacing are received comprises a flip-flop circuit to the normally non-conducting tube of which the input pulses are applied and also to a pulse delay means connected to the grid of the normally conducting tube of the flip-flop an output being derived from the anode of the normally non-conducting tube. The Figure shows a circuit for producing an output pulse at terminals 33, 34 in response only to pairs of input pulses applied at 22, 23 having a predetermined time spacing. The input pulse train is applied to the supressor grid of tube V1 which is normally non-conducting and also via delay network 24 and amplifier V3 to the control grid of tube V2 which is normally conducting. A first positive-going pulse of a pair supplied to the supressor grid of tube V1 will have no effect since the tube is cut off at its control grid. The pulse is then phase delayed in network 24 by a time equal to the predetermined spacing and applied to phase reversing tube V3 so that when it is applied as a negative going pulse to the control grid of tube V2 this tube is cut off and the flip-flop changes over with tube V1 conducting The recovery time of the flip-flop is such that when the second positive going pulse of a pair having a predetermined spacing is applied to the suppressor grid of tube V1 it finds the tube conducting so that current now flows to the anode of the tube and an output pulse is produced at terminals 33 and 34. If the second pulse of a pair occurs before or after the predetermined time interval it will find the tube V1 in its non-conducting state and therefore being applied to its suppressor grid will produce no output pulse. If the wanted pulse pair has pulses alternatively positive and negative-going the amplifier V3 is not required. The network 24 may be replaced by a further flip-flop circuits

Title: Apparatus for providing a visual display as a function of time of variations in value of a timedependent quantity
IPC: G06F19/00
Filed: 1970-04-10
Abstract: 1310991 Electrocardiograms SIEMENS AG 10 April 1970 [11 April 1969] 17283/70 Heading G1N [Also in Division H4] Time-dependent analogue signals (e.g. electrocardiographic) are converted to digital form in an A-D converter 1 and supplied via switch contact 2 to a shift-register store 4 from the output of which the digital signals are supplied via a D-A converter to the vertical deflection means of a cathode-ray display tube 10 the horizontal (timebase) deflection of which is produced by means 7 controlled by a control generator 5. The latter controls A-D converter 1 to pass a datum to the input of store 4 every 20 ms. and controls the shift of this datum towards the store output. The store has storage locations for 500 eight-bit words and a total feed-in time of 500 Î 20 ms = 10 sec. is required to fill the store initially. When the store is full, contact 3 is engaged and the data is circulated once in a period of 20 ms and simultaneously fed to D-A converter 6 to produce the display. Contacts 2 and 11 are then selected so that a new datum is fed into store 4 and the oldest datum fed out to a store 8, and via D-A converter 9 to a recording device which produces a permanent record. This cycle then continues until a complete record is produced. At the normal operating speed a new datum requires 10 sec. to reach the recording device but a "rapid-record" mode in which there is substantially no delay may be employed. The horizontal deflection means 7 may produce a ramp or a stepped curve and if desired the normal left-to-right motion of the display across the tube screen as new data is fed  into store 4 may be arrested and a stationary display of the non-updated data may be produced. Means may be provided to detect changes in rhythm of the cardiograms and to indicate such by a momentary increase in beam intensity at the position of such change (this intensity increase following the anomaly as it travels across the screen). Alternatively, an indication may be given by superimposing a high-frequency deflection waveform on the vertical deflection means to increase the width of the corresponding portion of the curve. The arrangement may be extended to allow the display of a plurality of time-dependent quantities as shown in Fig. 2
