Abstract: 1,267,193. Photographic colour printing. PAVELLE Ltd. March 11, 1969 [March 11, 1968], No. 11748/68. Heading G2A. A method of photographic colour printing in which exposure of all colour components of the printing material initially takes place simultaneously and is controlled photo-electrically to be terminated automatically when sufficient exposure has taken place has all but one of the colour components terminated by the introduction into the exposing light beam of an appropriate subtractive filter, the one colour component being terminated by the introduction of a plurality of additive filters introduced simultaneously into the exposing light beam, different ones of the additive filters filtering different areas of the exposing light beam. Preferably the additive filters pass equal amounts of the other colour components and thus reduce the intensity of these components by a factor of two. The intensity of the exposing light beam may be proportionally increased upon insertion of the additive filters, and the one colour component is preferably the red component. A colour head for carrying out the above method includes two pre-focused lamps mounted side-by-side and adjacent to a carrier containing two filter elements for each filter. The filters are moved into and out of the exposing beam by solenoids. The light after filtering passes into a diffuser box having an opal diffuser and thence illuminates a negative or transparency.

Abstract: 1290754 Packaging; applying adhesive tape AKERLUND & RAUSING AB 15 June 1970 [20 June 1969] 28920/70 Headings B8C and B8F A packaging machine of the general form described in Specification 1,290,755 has rollers 65 on its U-shaped carton holders 30 so that, at the sealing station, the pressure imposed by the sealing shoes 42 can be evenly distributed to fixed frame members with low friction between the holders and the frame. The rollers 65 adjacent the holder drive chains 25 and 26 run permanently on frame members 68. As illustrated, the holders are passing through a station for sealing the lower ends of the cartons 11 and at this station, the lower left hand rollers (as seen in Fig. 3) run on a fixed member 67. At a subsequent station for sealing the tops of the cartons, the top left hand rollers will run on a similar member. In order to ensure even application of pressure to the holders and to ensure that sealing pressure is adequately applied to the carton flaps 21, a bar 66 is placed during sealing so that its limb 77 lies between the flaps 21 and holder lugs 78. The bar 66 and its mounting bar 80 are moved in orbital manner at the sealing station by drive chains 95. The chains are connected to the bar 80 by pins 101 carrying guide rollers 108 which contact fixed guide channels 110, 111 during the straight runs of the chains 95. So that variations in the positions of the holders 30 and the lugs 78 can be accommodated, the mounting of the bar 66 on the bar 80 includes coil springs and Belville springs, Figs. 6 and 11 (not shown), so that the bar 66 can float both vertically and horizontally,

Abstract: 1294970 Work-holders DAYTON PROGRESS CORP 22 Oct 1970 [29 April 1970] 50268/70 Heading B3B A work-holder, for holding a tool or a workpiece, has a bracket 35 pivotally mounted on a base 10 and mounts a pair of rollers 60, 60<SP>1</SP> for receiving and supporting between them the tool or workpiece; a bearing device presses the tool or workpiece against the rollers, one of which presents a resilient surface to the workpiece or tool.  As shown, the device includes driven rollers 60, 60<SP>1</SP>, the latter of which is mounted on a shaft which is relatively eccentric to a mounting portion (Fig. 5, not shown), whereby the spacing between rollers 60, 60<SP>1</SP> can be varied. One or both rollers has 0-rings 67 (Fig. 4) for transmitting drive to a workpiece supported by the rollers. Drive to the latter is from an electric motor 13 via a toothed belt 18. The bracket 35 upon which the rollers are mounted can be tilted relative to the base 10 of the device, e.g. for producing a taper on a workpiece. Thus, a rod 32 acting between the base and bracket affords a pivot axis. The degree of tilt is determined by the use of a selected gauge block inserted between parts of the base and bracket. The tilt is adjustable by means of a device embodying nuts 41 and a screw 39. A lever 65 is pivoted to bracket 35 and, via a roller 97 applies a force to urge a workpiece into contact with the rollers 60, 60<SP>1</SP>. The roller 97 may be set to rotate about an axis which is inclined at a small angle to the axes of rollers 60, 60<SP>1</SP>, whereby axial movement of the workpiece can be achieved. The force is determined by a lever 84 which co-operates with cam surfaces 87 on lever 65. Front and rear adjustable work stops 104, 99 are provided. In a modification (Figs. 7, 9 and 10, not shown), the roller 97 is replaced by a device embodying a pair of spaced rollers (120) at one end and a thin blade (115) at the other end.

Abstract: 1295031 Tyre underinflation indicator BENDIX CORP 1 Jan 1970 [22 Jan 1969] 61/70 Heading B7C [Also in Division G1] A fluid pressure sensing device 10, 11 for detecting pressure changes in a rotating chamber 14 comprises a piston 28 movable by pressure changes within a cylinder 26 having an open end 27, a magnet 32 located axially of the cylinder, a tubular magnetic shield 31 surrounding the magnet, the magnet and shield being relatively, axially movable in response to movements of the piston, a resilient means 34 for biasing the piston against the fluid pressure, and a magnetic flux sensing coil 11 of conductive wire to be stationarily positioned near the rotational path of the magnet, the coil being suitable for connection to a warning system. In a first embodiment permanent magnet 32 is immovably mounted within a cylinder 26 of non-magnetic material which is open at 27  to the pressure being sensed. Piston 28 is biased against this pressure by spring 34 and has a part 31 attached (called the keeper) which at the correct pressure surrounds the magnet (Fig. 2, not shown). Piston 28 and keeper 31 are of magnetic material so that at the correct pressure, the magnetic flux hardly if at all extends beyond the end 33 of the cylinder. When the pressure is reduced, the piston and keeper withdraw from the magnet as shown in Fig. 3 and the flux extends beyond end 33. Alternatively (Figs. 4, 5, not shown) the magnet (41) is mounted on the piston stem (39), the keeper (42) is fixed, and reduction of pressure in the chamber causes the piston to retract the magnet (41) into the cylinder and into the shield provided by the keeper (42) thus removing the flux outside of the cylinder. The flux, when outside of the sensing device, passes through coil 11 as the chamber rotates and generates an e.m.f. which provides a warning signal by causing a light to flash (Fig. 6) or by operating a switch (Figs. 7, 8) causes a light to come on or go off as desired. Fig. 1 shows the device 10 in place on a vehicle wheel, detecting pressure in an inflated tyre.

Each converter receives corresponding bits of the two numbers, one being in inverted form. The output at the resistor is determined by the nature of the inputs, e.g. if a, b are both " 0 " at 0V the output is 0V, if they differ one at " 0 " and the other " 1 " at 10 V the output is 5 V and if both are " 1 " the output is 10 V. The AND gate is arranged to provide a " 1 " output if the inputs are at 5 V or 10 V. The OR gate provides an output only for inputs at 10 V. If the numbers are equal all outputs are at 5 V. The AND gate provides a " 1 " output, inverted at 4 and supplied to the OR gate which provides an " 0 " output which is inverted at 5 to give a " 1 ". If any corresponding bits differ a " 0 " is supplied to the AND gate providing a " 1 " input at 3 and hence a zero at y and/or the converters feed a " 1 " to the OR gate providing a zero at 5. For each extra digit added to the number two resistors and two diodes (in the gates) are required.
