Filed: 1973-01-01
Abstract: 1421991 Photo-electric measurement of colour GRETAGAG 1 Jan 1973 [31 Dec 1971] 83/73 Heading G1A [Also in Division G2]  An optical system for projecting light from a source O on to the surface of a specimen 1 and focusing the light reflected from the surface, for use in measuring the reflective properties of surfaces, comprises a condenser lens 11 having a first spherical surface 57, a record spherical surface 56 concentric with the first, and a third annular surface 14 whose centre of curvature coincides with the measuring spot B; vapour deposited annular reflecting surfaces 13, 12 are provided on the lens surfaces 57, 56 as shown, and a positive lens 31, which may be of the same material as the lens 11, is provided within the reflector 12. The light patch in the system is as shown. Light finally leaving the lens 11 is deflected by a reflector 34 on to a photodetector 36. Alternatively Fig. 3 (not shown) it may be split into two beams, one of which is chromatically analyzed by a dichoric system and three photo-detectors, the other reaching a fourth photo-cell via a diaphragm which may be smaller than the image of the measuring spot to permit the study of details in the spot. These facilities may be used for chromatic measurements on intaglio printing machines. The reflector 12 may alternatively be deposited on the surface of the positive lens 31, Fig. 2 (not shown), when it also serves as a diaphragm In a simplex measuring head for measuring the reflective properties of surfaces Fig. 3 (not shown) the ilumination system of Fig. 1 may be preceded by a condenser system which is similar to the illumination system but has a reversed optical path, the measuring spot B being replaced by a light source, and in which the positive lens 31 is omitted, the reflector 12 being correspondingly extended. A multiplex measuring head for monitoring the colour of off-set printing machines Fig. 4 (not shown) comprises four of the illumination systems of the invention; a light source is surrounded by two of the above condenser systems; one of the resulting beams passes via two reflectors and three field lenses to one illumination system which measures the brightness of the object; the other beam is split into three by two dichoric chromatic beam-splitters, each beam passing to an illumination system via a field lens, two of the beams also passing via optical primatic compensating elements; these three illumination systems provide a chromatic anaylsis of the object with respect to the three primary colours.  Optical data are given for one example of the measuring head of Fig. 3.

Title: Reel for optical fiber
Inventor: SHIBATA MASAYUKI
IPC: G02B6/00
Filed: 1998-01-05
Abstract: PROBLEM TO BE SOLVED: To easily take out a reel for optical fiber from closely packed ones by providing a hole in which a finger or a bar is put at a prescribed location in the vicinity of the outer end of each collar of the reel for optical fiber having collars at both the ends. SOLUTION: One (A), two (B) or three (C) of holes 12 having sizes to be put by fingers are provided in the vicinity of the outer end of a collar 11 of a reel 10 for optical fiber by passing each of the holes 12 through. These holes 12 are located at the outside of a location where an optical fiber 20 is wound. If the locations of the holes 12 of collars 11 on both the sides are made the same location for the peripheral direction, that is, a line connecting the holes 12 is made the same direction as the shaft of the reel 10, the reel 10 is made easy to be vertically lifted and this matter is desirable. The number of holes 12 may be one or two or more per collar 11. When the number of holes 12 is small, the reel 10 is packed so that holes 12 may be located upward. When the number of holes 12 is increased, the reel 10 is packed without caring the locations of holes 12.  The size and the number of holes 12 are made to the extent to prevent strength of the collar 11 from lowering.

Abstract: A polymeric oxychloride is produced by forming a solution of a chloride of trivalent aluminium, phosphorus, ­P =O, chromium and iron, or of tetravalent titanium, tin, germanium, zirconium, thorium, and uranium, the chloride having at least 3 chlorine atoms directly attached to the element, in an inert solvent comprising one mole per mole of the chloride of a dialkyl ether having not more than 8 carbon atoms per molecule, treating the solution with one mole of water per mole of chloride to effect partial hydrolysis and then eliminating hydrogen chloride between molecules by heating to form the polymer. The ether may be diethyl ether, either alone or mixed with carbon tetrachloride. The water may be added in portions to the refluxing mixture, the inert solvent then being removed to produce the polymer in syrup-like form.  Higher molecular weight polymers may be produced by heating the polymers obtained after removal of the solvent to between 50 DEG  and 120 DEG C.  If desired, mixture of different chlorides may be used to produce a mixed polymer.  The product, or its etherate, may be reacted with water to hydrolyse it and replace the chlorine atoms by hydroxyl groups.  According to the Provisional Specifications, chlorides of boron, aluminium, titanium, germanium, tin, zirconium, hafnium, thorium, phosphorus, arsenic, antimony, bismuth, sulphur, selenium, tellurium, chromium, molybdenum, uranium, rhenium, iron, cobalt, and nickel may be used in the process of the invention.

Filed: 1973-01-03
Abstract: 1366471 Radio Signalling MOTOROLA Inc 3 Jan 1973 [17 Jan 1972] 390/73 Heading H4L The invention relates to a muting circuit in a receiver for an information signal having a predetermined band width 21, Fig. 2, but which when transmitted, using, e.g. Delta modulation and a scrambler, occupies a much wider bandwidth 15. Receiving circuits 16, Fig. 1 are followed by a decoder 17, which is coupled to audio circuits 32 via a muting switch 18. The output from decoder 17 is also fed to a first bandpass filter 19, passing a band substantially equal to that 21, Fig. 2, occupied by the information signal, and also to a second bandpass filter 20, passing a band, e.g. 50-150 Hz., which falls within the range of frequencies occupied by the encoded signals but outside the band 21 occupied by the information signal. The outputs from filters 19, 20 are amplified by amplifiers 25, 28 respectively and rectified and smoothed by integrators 26, 29 respectively, the outputs of which are amplified in differential amplifiers 27, 30 respectively. The output from amplifier 27 is applied directly to OR gate 31 and the output from amplifier 30 after inversion, so that if a properly decoded signal is present in the channel 19, 25, 26, 27 an output is derived from OR gate 31 which closes switch 18 to unmute the receiver. If, on the other hand, there is no output from amplifier 27, or if there is an output from amplifier 30, caused by a signal coded differently, no output is obtained from OR gate 31 and the receiver remains muted. The arrangement is more particularly intended for a paging system, a transmitter 10 being also provided and microphone 34 which is followed by amplifier switch 35 which has an output which applies a muting bias to switch 18 during transmission, in which amplifier 35 is coupled to transmitter 10 via bandpass filter 19, amplifier 25 and coder 12. The Specification also describes a detailed transistorized circuit (Fig. 3, not shown).

Abstract: 1490791 Arithmetic and logic units COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 6 Jan 1975 [7 Jan 1974] 392/75 Heading G4A A microprogram-controlled arithmetic and logic unit, for the processing of pairs of eight-bit bytes consisting of pairs of four-bit BCD numbers received from a bit string, comprises multibyte stores RDA, RDB whose respective outputs A, B are fed to an arithmetic and logic unit #D, the storage capacity of store RDB being much larger than store RDA so that store RDB may be used as a buffer store. The incoming bytes are received at an input INF of a multiplexer TS controlled by the control code KTS of each microinstruction and pass via a multi-byte register RS to an input s of a multiplexer TD, and also to an input of a circuit #P whose output p is connected via the multiplexer TD to inputs of the stores RDA, RDB. The circuit #P adds the decimal value '6' to the first and second half of each byte, and a correction circuit #M may be enabled to subtract '6' from the output of the ALU #D for carry correction purposes. A register EC is loaded at the beginning of each microprogram with a quantity representing the number of elementary steps in the microprogram and is successively decremented after the execution of each microinstruction; the contents of register EC are compared each time in a comparator circuit COMP with the contents of a register CT loaded from the preceding microinstruction. If equality is not found, the read-out bytes from store RDA are applied via multiplexers T1, T2 as respective inputs f, z to the multiplexer TD. If the contents of registers EC, CT are equal, multiplexers T1, T2 respectively add '6' and the contents of a register AT to their respective halves of the bytes (register AT being loaded at the beginning of the microprogram with an index value). The stores RDA, RDB may be read-out simultaneously, and read-out of store RDA may be simultaneous with write-in to either store, but the stores may not be written-into simultaneously. The multiplexer TD, whose structure is given in Fig. 2 (not shown), may transfer the following quantities to its eight-bit output d, where subscript 1 represents the first group of four bits of a quantity and subscript 2 the second group of four bits of the quantity: (1) S 1 ,S 2 (2)p 1 ,p 2  (3) p 2 , p 1 , (4) '5', p 2  (5) '5', p 1  (6) # 2 , p 2  (7) f 1 , p 1  or (8) p 2 , z 1 . Details of the arithmetic and logic unit #D are given in Fig. 3 (not shown). The operations performed by unit #D include addition, subtraction, intersection, transfer, OR and XOR.
