Title: Method and an arrangement for reading coded information from a data carrier
IPC: G06K7/14
Filed: 1974-11-12
Abstract: 1494337 Card reader ID-KORT AB 12 Nov 1974 [30 Nov 1973] 48903/74 Heading G4M A reader for a card such as an identity card or authorization pass has a plurality of sensors for an equal plurality of data channels on the card and two spaced sensors for a control or clock channel on the card. The control or clock sensors are spaced in the direction of travel of the card when a reading operation is performed. The card is inserted into the reader by hand and operates a presence detector, e.g. a contact which activates the reader. The first of the control sensors supplies a control signal I to a buffer store B1 and comparators C1 and C4. The other of the control sensors supplies a control signal II to a buffer store B3a and comparator C4. The data sensors feed a buffer store B3b. Comparator C1 feeds a delay 22 which feeds a delay 23, buffer store B1 and AND gate 24. Each time the signal at the clock track changes comparator C1 detects inequality between the clock track and the buffer store and supplies a pulse to delay 22. After delay # the buffer store stores the clock track signal and the comparator detects equality. So a clock pulse of duration # is produced by the comparator. The clock pulse is fed to a counter R via delay 23. The counter is incremented or decremented in dependence on a signal from comparator C4. The signal from C4 indicates the direction of movement of the card so a high signal, which indicates inequality at the comparator, indicates that the card is moving in the opposite direction to the intended read-out direction. The AND gate 24 enables readout of data when the counter holds a zero count, the delayed clock pulse arrives and comparator C4 indicates the card is moving in the correct direction. If the direction of the card movement changes during read out then a strobe pulse is not produced until the card is moving correctly and has reached the position at which it was reversed (Figs. 4A-4D and 5A-5D, not shown). An alternative circuit (Fig. 6, not shown) includes intermediate buffers stores I and II and comparators I and II between the two reader means and third buffer store and comparator of Fig. 2 to cause a clock pulse to occur when a change of character occurs in any of the data tracks so that a clock track is not required.

Abstract: 1350082 Pistons ADSHEAD RATCLIFFE & CO Ltd 15 Nov 1971 [17 Oct 1970 27 Oct 1970] 49407/70 and 50911/70 Heading F2T A piston for use in dispensing viscous substances, such as mastic sealant, from a cartridge comprises a crown 5, skirt 6 and one or more grooves 10 formed in the outer surface of the skirt, the grooves, when the piston is mounted for co-operation with the cartridge wall, providing a passage which permits escape of air past the piston but does not permit appreciable leakage of the viscous substance. The piston may be made of synthetic plastics material with a concave crown and a skirt strengthened with internal circumferential ribs 11. The grooves 10 may be parallel with the piston axis, angled or helical. When the piston is first inserted into the cartridge, the air trapped between the crown and substance to be dispensed flows past the piston through the grooves 10. The skirt may be tapered towards the crown as shown so that during a dispensing operation when force is applied by a plunger 9, the leading edge of the skirt is expanded into sealing engagement with the cartridge wall due to the flattening out of the crown. In a modification, the grooves stop short of the rear edge of the skirt and the rear edge is in sealing engagement with the cartridge wall; when the piston is first inserted, the trapped air passes along the grooves and lifts the rear edge of the skirt to permit its escape.

An endless belt 45 moves a copy sheet 34a to the exposure station at which time the system 6 starts its movement towards position 6A. A photo-sensitive drum 15 rotates in contact with sheet 34a as system 6 moves and has light from an original directed thereon by a projection lens 12 and filter 14. As it passes over copy sheet 34a the latent image is transferred thereto and then belt 45 takes the sheet 34a round to the developer units 52-55, the operative unit corresponding to the colour complementary to that of the filter 14. One cycle is used for each colour and subsequently the sheet 34a passes out of the machine via a heat fixing device 69, 70-72. In another embodiment the developer units are moved by a conveyer after each cycle so that they each in turn contact a respective roller on an assembly of four rollers which roller then moves with the system 6 to convey developer to the copy sheet 34a. In other embodiments three photo-sensitive drums are used and are pulled across the copy sheet one at a time or, if each drum has an associated projection device, all the drums may be pulled across together. In these embodiments the drums each have associated developer units, which move with the drums.

Title: Improvements in or relating to receiving and transferring devices for telegraph signals on the start-stop principle
IPC: H04L25/45
Filed: 1966-11-14
Abstract: 1,145,109. Telegraphy. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 14 Nov., 1966 [17 Nov., 1965], No. 50910/66. Heading H4P. A circuit for connection between an incoming line 1 and a telegraph exchange comprises a serial-parallel converter OV which is set in operation for the duration of one 7-bit character signal when it detects a bit of Start polarity. The received signals pass, via switch T, either direct or via an inverter I to the converter. The switch reverses if the seventh bit fed to the converter has Start polarity. If the inverter I is in circuit the seventh bit delivered by the converter is opposite in polarity to that bit at the converter input. In the embodiment illustrated, the seventh bit from the converter controls the state of bi-stable FF, which controls switch T. Bi-stable FF also controls the inversion of the seventh bit in the converter. When the circuit is at rest the inverter is in circuit, and so idle line signals (continuous Start polarity) have no effect on the converter. When a call (continuous Stop) is received, the converter starts and delivers a seventh bit of Stop polarity; FF changes to 0-state, switch T reverses, and subsequent Start-Stop data passes direct to the converter. At the end of transmission continuous Start polarity on line 2 causes the converter to deliver a seventh bit of Start polarity which reverses FF and hence switch T, putting the circuit at rest. The signal on line 3 may be used for control of supervisory or alarm circuits.

Title: Metallizing process
IPC: C25D5/56
Filed: 1964-12-16
Abstract: A metal layer is bonded to a non-metallic object by moulding a non-metallic composition having dispersed therein a filler consisting of metal particles, preferably filaments, e.g. of Cu, Ni, Zn or Ag, and friable non-metallic conductor particles, e.g. of graphite or other conductive carbon or conductive or semi-conductive metal salts, removing a surface of, e.g. by etching, vapour grit blasting or otherwise abrading, and metallizing, preferably electroplating, the moulded object.  The process is particularly suitable for chromium or rhodium plating of resinous polymer plastic articles, but can be used for other nonmetallic compositions, e.g. paper, ceramics or rubber. Preferably the volume proportion of filler in the composition is 0.2 to 0.7 and of metal in the filler is between 0.01 and 0.7. The filler may be incorporated into a plastic matrix before or after polymerisating, being kneaded into the polymer particles by ball milling; for a thermosetting resin such as of melamine-formaldehyde, moulding may be effected at the curing temperature of the resin. An initial ductile base-plating of copper and/or soft nickel may be applied from fluoborate baths on to the surface of the moulded object, sufficiently etched e.g. with sodium hydroxide, aqua regia, sulphuric or nitric acid to expose dispersed metal particles, prior to chrome plating from a chromic acid bath.
