Abstract: 1,163,137. Authenticating bank notes. P. THURNBERGER. Dec.7, 1966 [Dec.11, 1965; Oct.1, 1966], No.54718/66. Heading G1A. Apparatus for determining whether bank notes have been produced by simultaneous printing and include steel gravure printed areas, comprises an arrangement for checking the registration of the printing on both sides, and a means for measuring variations in thickness arising from the steel gravure printing. Both sides of the note are scanned in synchronism by a photoelectric system and the resulting signals are compared, and the thickness is subsequently measured by a feeler attached to a pressure sensitive transducer such as a Piezo-electric crystal or a strip extensometer. The thickness may be gauged by a pair of feeler capacitor electrodes connected in a high-frequency resonant circuit, and the boundary dimensions may be verified by a plurality of contacts mounted on an insulator on one side of a note and a conductive plate on the other additional contacts across the note may be used to reveal torn or holed notes. The surface may additionally be photo-electrically inspected for reflectance and colour. Reference signals may be on a magnetic tape.

Abstract: 1301678 Abrading UDYLITE CORP 11 Nov 1969 [12 Nov 1968(2)] 55075/69 Heading B3D [Also in Divisions B1 B2 B6 B8 C7 F1 and F4]  Workpieces being treated in a conduit by a helically flowing stream of fluid are conveyed along the conduit and are rotated by the fluid stream. Different treatments can be effected on the same workpiece with different fluids in different consecutive stages, one of which is shown in Fig. 1b where fluid from reservoir 34<SP>1</SP> is pumped via conduit 50<SP>1</SP> and 52<SP>1</SP> into inductor 32<SP>1</SP>, through which inductor the workpiece is also introduced from 38<SP>1</SP> into conduit 30<SP>1</SP>. Figs. 2A and 3 show suitable inductors. In Fig. 2A, fluid from pump 54 flows through an annular gap in which inclined vanes 95 impose a helical motion to the fluid flow, and the suction caused by the gas flowing into and along conduit 96 sucks in the workpiece 84 into conduit 96. Further fluid from the annular slit in ring manifold 86 lubricates the passage of the workpiece through P.T.F.E. tube 80. The invention may be used for abrasive surface treatment by employing a treating fluid incorporating abrasive particles supended therein.

Title: Adaptive delta modulation system
IPC: H04B14/06
Filed: 1974-12-18
Abstract: 1487410 Delta modulation FUJITSU Ltd 18 Dec 1974 [28 Dec 1973] 55176/74 Heading  H3H In an adaptive delta modulation system, mistracking is reduced by counting the number of bits in the delta bit stream since the last change in quantizing step size and reducing the step size when this count reaches a value dependent on the step size. In Fig. 2, a one-clockperiod-delay 22 and EX NOR gate 23 detect the occurrence of 2 consecutive similar bits in the delta bit stream output of comparator 2. A counter 24 counts the number of consecutive similar bits N, threshold circuit 25 incrementing a quantizing-step-size-determining counter 26 by one when N reaches, e.g. 4. Counter 29 counts the number of consecutive alternating bits M, threshold circuit 28 decrementing-the counter 26 by one when M reaches, e.g. 5. Counter 30 counts the number of bits K (regardless of their logic state) since the last step size change, and logic 31 decrements the counter 26 by one when K reaches a value dependent on the state of counter 26, i.e. on the quantizing step size. If outputs from 25 and 31 occur simultaneously, inverter 36 gives precedence to incrementing. Logic 27 inhibits incrementing and decrementing of counter 26 when it contains 111 and 000 respectively. Various values of N, M and K are given.

Abstract: 1425009 Packaging cigarettes; labelling machine GD SpA 23 Feb 1973 [29 Nov 1971] 55390/71 Headings B8C and B8F A cigarette packaging machine transfers batches G of cigarettes from pockets 1 of intermittently moving endless conveyer 2 to a series of stages A-E in which each batch is wrapped in lined foil 6, and then in a label 22, the cigarettes moving transversely to their axes at each stage. At stage A each batch is gripped by jaws 4, 4a of a wheel which rotates through 180 degrees to a position where transfer members 8, 8a push the batch through a blank 6, which thereby takes a U-shape, into a pocket at B<SP>1</SP> of the intermittently rotating wheel at stage B. The blank is wrapped and folded about the batch by means of oscillating fingers 10, 10a, folder 13, fingers 15, 15a, fingers 16, 16a and 17, 17a, and by engagement with projections of edge 14. At station B<SP>V</SP>, the wrapped batch is transferred to a rotary folding stage C, similar to stage B, where a label 22 is wrapped round the foil wrapping. At station C<SP>V</SP>, the packet is transferred by members 27, 27a to a pocket of a rotating wheel at stage D where the label flaps are glued and pressed together by buffer block 32. The packet is finally moved to stage E by pusher-lifter 33, and a pusher 34 and fork 35 apply a glued endseal label to the packet which then proceeds along plate 36 for ejection by wheel 41. The pusher pushes the packet through the prongs of the fork 35 which has seated astride it, and held by vacuum, a revenue stamp or sealing label. When the suction holding the stamp or label ceases the packet passes through the fork prongs. A section 36a of the plate 36 is heated to dry the glue which is used to join the two flaps of the label turned down in stage C.

Title: Small Light Source Detection System.
Inventor: HAYDEN JOSEPH PAGE
IPC: G01S3/78
Filed: 1967-12-06
Abstract: 1,197,780. Detecting small light sources photo-electrically. J.P. HAYDEN. Dec.6, 1967 [Dec. 7, 1966], No.55473/67. Heading G1A. The presence of a small light source in an optical field is detected by dividing the field into a plurality of sets of elemental areas, receiving light from each set with a separate photosensitive element and sensing inequality of the outputs from the photo-sensitive elements due to the presence of a small light source in the field. Oncoming car headlamps may be detected for an automatic dipping system. The optical field is imaged by a lens 11, Fig. 1, on to a reflector having a first set of surfaces 14a-14d reflecting light to a first detector 16 and a second set of surfaces reflecting light to a second detector 17. The detector outputs are sampled alternately and the presence of a small light source causes an A.C. signal. Ambient light and large area sources which illuminate detectors 16 and 17 substantially equally cause a D.C. signal only. The A.C. signal may be detected by clamping its lower level and applying it to an integrator the output of which is detected by a peak detector. In a modification, Figs. 7-10 (not shown) the reflector has three sets of surfaces directing light to three detectors, the outputs of which are sampled, sequentially. In another embodiment the reflector may be replaced by a plate having alternate transparent and reflective stripes with the detector 16 located behind the plate, Fig.5 (not shown). Alternatively the reflector may be replaced by a prismatic beam splitter with complementry grids in front of the detectors, Fig. 6 (not shown).

Abstract: 1,206,120. Digital transmission systems; facsimile transmission. XEROX CORP. 21 Dec., 1967 [27 Dec., 1966], No. 58023/67. Headings H4F and H4P. Serial binary data is inspected in successive groups of bits by an encoder which passes the groups encoded or unchanged in accordance with the probability of occurrence of particular sequences of bits. The encoder output contains less bits than the input. A decoder for the inverse process is described. The encoder, Fig. 4 (not shown), inspects two-bit groups and operates as shown in Fig. 1. The group most likely to occur is, in this example, 11. If a group is not 11 then the group is sent unchanged and the next group inspected. If the group is 11 it is sent as 11 and the next group inspected. If this next group is also 11 it is sent as 0, and if not 11 is inspected to see if it is 00. The coding continues as shown. The decoder, Fig. 5 (not shown), inspects received two-bit groups but if a 11 is received it inspects subsequent one-bit groups, as indicated in Fig. 2 (not shown) to reconstruct the original serial data.
