Abstract: 1296419 Magnetic storage devices COMMISSARIAT A L'ENERGIE ATOMIQUE 29 May 1970 [6 June 1969] 26157/70 Heading H3B Parallel magnetically coated wires of a storage device are separated by spacer wires or threads. To make the device, spacer wires A and B, Fig. 2a, are laid on an adhesive support S; orthogonal conductors E are adhered to the spacers, Fig. 2b, and then the support and wires A are stripped away to leave parallel grooves R, Fig. 2c, into which the coated wires are placed. Finally, the conductors E are folded across the top of the Fig. 2c structure to give maximum coupling with the coated wires. Fig. 3 shows the conductors E adhered to a hexagonal cylinder, spacer wires B being wound thereon. Coated wires (not shown) may be placed in the grooves between adjacent spacers and connected to terminals F, or alternatively the grooves may be filled with further spacers after which the assembly is encapsulated and the further spacers are removed to leave tunnels into which the coated wires are inserted. The spacers may be conductors or insulators, and may be magnetic to aid flux closure. Two spacers and their associated coated wire may be electrically interconnected. The substrate may be conductive.

Abstract: 1303583 Electro-photographic copiers PENTACON DRESDEN KAMERA-UND KINOWERKE VEB 10 June 1971 19961/71 Heading G2H In order to make positive copies from both positive and negative originals using the same developer, an electro-photographic copier includes a reversal switch 3 in the circuit of its charging device 1 so that the polarity of the sensitizing charge applied to a drum 2 can be chosen accordingly. To compensate for the different reaction of drum 2 to different charge polarities, switch 3 may be coupled to a switch 5 in H.T. supply 4 to reduce the voltage when charging with positive polarity. Alternatively, compensation is provided by switching a resistor into the charging or exposure lamp circuit, or by using a filter or diaphragm for the lamp, or by altering the charging time or the distance between device 1 and drum 2. Residual potential may be removed by infrared. The copier is particularly intended for enlarging microfilm.

Title: Web break detector
IPC: B65H26/02
Filed: 1970-01-23
Abstract: 1312111 Web break detectors HOE-CRABTREE Ltd 13 Jan 1971 [23 Jan 1970] 3506/70 Heading B8R A web break detector apparatus, associated with a printing machine which is supplied with a selective number of contiguous webs, is provided with a number of sensing members which are associated with a device, the device being arranged to provide a signal in response to the members sensing the absence of webs in the sensing zones and to be prevented from operation whilst the members make an initial sensing operation following start up of the machine but to be rendered inoperative to stop the machine when all the members sense the absence of webs when the machine is running at full output speed. Each web is associated a sensing member 21 in the form of a nozzle producing a fluidic signal at a sensor 22 coupled to the input of a fluidic NOR-gate 23 and a fluidie flip-flop 24 to set the latter to its switched-off state, the NOR-gate being operative to actuate an OR-gate 26, associated with an electric relay 27 in the circuit of a web severer and machine stopping, only when all three inputs are of zero fluidic value. To prevent operation of the NOR-gate 23 during starting up of the machine and until the machine has attained its full output speed and to prevent stopping of the machine due to sensing of the absence of web in a sensing zone in which the web has been omitted (not required for printing) all sensing zones are provided with fluidic valves 25 which during start up are supplied with fluidic signals. The signals are applied to the NOR-gate 23 to provide a positive signal and to the input of the flip-flop 24 to switch the latter on such that positive signals can be applied to the gate 23 and to the flip-flop 24, which is therefore mentioned in its switched-off position, by the sensor 22 when a web is present across the sensing member 21. The NOR-gate is inhibited due to the presence of web at the sensing zone and due to two positive signals being supplied to the gate 23. If a web is absent at the sensing zone the gate is still inhibited during the start up period since during this period the valve is supplied with the positive signals which are also applied directly to the gate. In the case of continued intended absence of the web at a selected sensing zone the machine is not tripped when at full speed in that the last positive signal from the valve 25 has switched on the flip-flop 24 which prevents the gate 23 from actuating gate 26. However when a web breaks when the machine is at full speed the signal from the sensor 22 is interrupted and since the flip-flop 24 has been switched-off by the preceding signals from the sensor 22, the three inputs at the NOR- gate are coincident i.e. negative and the gate 26 is actuated to stop the machine and operate the severer through the electric relay 27. A similar function is performed by an electric circuit associated with a pivotable finger driven by an electric motor (Figs. 1 and 2).

The double pin hole arrangement can be such as to have moveable pin holes, or may be a screen having a plurality of sets of pin holes at different spacings. Modulator 13 or 28 is preferably arranged so that light only passes through one of the two pin holes at once.

Air from supply point A at low pressure registered by a gauge 6 is then pumped into chamber 8 until its escape through the seal 3 is prevented by the plug 2. At this point the gauge 6 sends a signal which de-clutches the rack pinion drive 18, Fig.2, and stops the spindle 1 from further downward motion. The axial displacement of the plug 2 to stop air escape is related to the seal diameter which is indicated on a scale 13. The spindle 1 may be slid further downwards, relative to the rack 12 which is now fixed, until a stop 16 abuts an end switch 17 operating a change over switch 9. This further movement flexes the seal 3 and air from supply point B at higher pressure is now pumped into chamber 8. The pressure at which air escapes through seal 3 is now measured by a gauge 7 whose scale is calibrated in flexibility units.
