IPC: G03C7/14
Abstract: 506,281. Reproducing images on lenticular films. OPTICOLOR AKT. - GES. Nov. 24, 1937, No. 32418. Convention date, Nov. 25, 1936. Drawings to Specification. [Class 98 (ii)] The gpadation of lenticular films is varied without affecting colour reproduction by forming thereon a supplementary image in the original emulsion layer or in an applied layer, the resolving power of the process for forming this image being less than that of the process of developing the original image in the film. The supplementary process may, for example, be one capable only of resolving details of the width of one lenticle. In one example, the film after development or an applied layer is sensitized with a bichromate, exposed through the lenticles and the unhardened areas dyed, e.g. with pinatype yellow or pinatypo blueblack. The resulting dye image is a negative of the original image. When the combined image is printed on a further film by light coloured similarly to the dyed image little change of gradation is produced. The use of light complementary in colour to the dyed image produces a large change in the gradation of the resulting image. The sensitivity of the bichromate may be increased by the use of known sensitizers, e.g. lanthanum chloride. In a modification, a silver halide emulsion of low gamma value is applied, exposed, and developed to a positive which enhances, or a negative which reduces the gradation of a copy made from the film. In printing from a. film produced as above, the sensitive surface may be arranged in front of aslightlyroughened reflector whereby an image corresponding to the gradation of the original as a whole is produced in addition to the normal image. The Specification as open to inspection under Sect. 91 describes also a developing process in which the film is first developed with a developer for producing fine grain and development is finished with a coarse grain developer. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to Methods and Apparatus for Removing Moisture from Organic Materials, Foodstuffs and other Moisture-Containing Substances.
IPC: B29C71/00
Filed: 1967-11-08
Abstract: 1,196,016. Drying finely-divided material. BALLESTRA S.p.A. 8 Nov., 1967 [16 Nov., 1966], No. 50725/67. Heading F4G. A method of drying finely-divided material (e.g. food or organic materials) comprises passing the material through a treatment chamber, introducing into the chamber a dehydrating gaseous fluid so that it passes in the same direction as the material, collecting the dried material and recirculating the spent dehydrating fluid in a closed circuit to the treatment chamber. The spent fluid is successively separated from any solid particles entrained thereby, initially cooled in a heat exchange, further cooled to remove by condensation vapours contained in the fluid, initially heated by heat derived from the initial cooling step, further heated to the desired temperature and reintroduced into the treatment chamber. The material may be passed through more than one chamber, the chambers being provided with a common fluid recirculating system or the chambers each being provided with a fluid recirculating system. In the embodiment shown, material from pipe 2 and dehydrating fluid from duct 7 are passed into chamber 1. The dehydrated material is discharged into tank 5 or is recirculated to top of chamber 1. The dehydrating fluid from chamber 1 is passed to cyclones 8, 10 in which any solid material is removed from the fluid. The fluid is then cooled in heat exchanger 11 and treated in dehumidifier 12 in which liquids absorbed from the material in chamber 1 are condensed from the fluid. The condensed liquids are separated in separator 13, the water being discharged through outlet 14 and the other liquids being returned to the treated material. The dehumidified fluid is passed through fog separator 12<SP>1</SP> and pump 15 is then returned to chamber 1 via heat exchanger 11 in which it is heated by the dehydrating fluid passing to the dehumidifier 12, and heat exchanger 16.

Title: Self-clocking punched tape reader
IPC: G11B20/14
Filed: 1973-11-01
Abstract: 1449236 Punched tape reader HONEYWELL INFORMATION SYSTEMS Ltd 31 Oct 1974 [1 Nov 1973] 50758/73 Heading G4M A reader for punched tape has for each data bit in a row two sensors RH1, RH2 sensing corresponding areas on the tape that are longitudinally displaced but overlapping. As shown there are two sets each having six sensors and the sensors from each set feed a respective OR gate G1, G2. Gate G1 via an inverter Il feeds a reset input of flip-flops SA1 which is set by a signal from gate G2 so that the flip flop is set for the period during which a hole is detected by any of the sensors RH1 and is reset when all the sensors RH2 detect no holes. The sensors also feed a comparator EQ1 producing a signal when the signals on the two lines 13, 14 are identical. Since some signals will rise later than others and some will fall earlier than others the pulse from EQ1 is shorter than that from SA1 and is wholly contained by that from SA1. Flip-flop SA1 and comparator EQ1 feed a one shot OS1 producing a short pulse passing the data from sensors RH2 via AND gate G4 and forming a strobe pulse STR. The inverted OS1 signal feeds a reset input of an error flip flop ER1 the set input of which receives the signal from flip-flop SA1. If two strobe signals are produced in a period in which only one should occur, i.e. if EQ1 goes true, false and true one shot OS1 produces two strobe pulses. At the end of the first strobe pulse ER1 is reset to enable AND gate G5 and the second strobe pulse passes gate G5 to produce a DST error signal. AND gate G6 is enabled by the set output of ER1 which is true for only a short period between the start of the SA1 signal and the end of the strobe signal OS1. if the comparator does not detect equality then ER1 is not reset and a signal on line ER1<SP>1</SP> enables an AND gate G6 which passes a signal at the end of the readout period.

Title: On-load tap-changing arrangement for star-point connection to tapped transformers or chokes
IPC: H03K17/725
Filed: 1969-10-20
Abstract: 1,236,505. Transformers. SIEMENS A.G. 20 Oct., 1969 [18 Oct., 1968], No. 51428/69. Heading H1T. In a tap changing arrangement for the star point of a polyphase transformer, two polyphase rectifier bridges 40, 50 are connected to tap selector arms 2, 3 respectively, each bridge having a respective controlled rectifier 60, 70 or mechanical switch. Fig. 1 (not shown) in its D.C. arm. The negative poles of the controlled rectifiers are connected by a capacitor 110 and the positive poles by a capacitor 150 such that when tap selector arm 3 is connected to a free tap, both capacitors charge to the differential tap voltage. When controlled rectifier 70 is then fired these capacitors cause twice the differential tap voltage to appear across the rectifier to be switched off thus ensuring its immediate switching off. Inductors 900, 800 help the smooth commutation process. By controlling the pulse inputs to the rectifiers the tap changeover can be made a gradual process. In Fig. 1 (not shown) interlinked mechanical switches are used instead of the controlled rectifiers, the discharging capacitors in this case suppressing the arc which develops at the " opening " switch.

Filed: 1975-12-18
Abstract: 1529859 Frequency dividers INTERNATIONAL STANDARD ELECTRIC CORP 18 Dec 1975 [21 Dec 1974] 51875/75 Heading G4D A system for producing a plurality of different clock pulse trains comprises a first store Spl which stores values representing the periods of the clock pulse trains; a second store Sp2 which stores a value representing the length of the pulses; a counting device which is advanced at fixed intervals by a reference clock Gen; and a comparator Vg1 which detects when the count in Sp3 is equal to the value in Sp1 to start a new pulse (and reset the counter to zero) and when the count is equal to the value in Sp2 to end the pulse.. As described, Fig. 1 provides 180 ms. pulses at various intervals up to 15 sees. for timing and pricing calls on a telephone system. The reference clock Gen. sweeps three switching devices W1-W2-W3 through all positions once every 10 ms. At each new sweep all the storage locations in Sp3 are advanced by one. At each step the comparator Vg1 compares the count in the respective storage location in Sp3 with the value in Sp2 which is fixed equal to 18 and with the corresponding location in Sp1. When the corresponding locations in Sp1, Sp3 agree a corresponding flip-flop FF is set and the value in that location in Sp3 is reset to zero. When a value in Sp3 is equal to Sp2 the corresponding flip-flop is reset. The outputs of the flip-flops are the set of clock pulse trains. Where periods are related Sp1 may have only half the number of locations as Sp3 and a divider (D) is introduced between Sp1 and the comparator on alternate steps of the switching device (Fig. 2, not shown). The various functions of Fig. I may be carried out by a microprocessor (Fig. 3, not shown); Sp3 is then a RAM and Spl a ROM or PROM. The store Sp1 may have several different values in each location, the required one being selected according to time of day to cope with varying tariffs.
