Title: Process for the manufacture of strongly basic porphins and products obtained thereby
Filed: 1932-12-20
Abstract: Basic porphins, capable of yielding water-soluble salts with strong mineral acids, are prepared by treating porphins containing a carboxyl or esterified carboxyl group with a basic compound of the formula <FORM:0407486/IV/1> wherein A represents an alcoholic hydroxyl group or an amino or substituted amino group, (CHy)x denotes a saturated or unsaturated aliphatic straight or branched chain, and R1 and R2 stand for hydrogen, alkyl, aryl, aralkyl or oxyalkyl groups.  The porphin starting material may be in the hydrogenated or oxidized form or as a metal compound and the basic compound may be in the form of the alcoholate or salt.  Examples are given of the interaction of (1) methyl-phaeophorbide and asymmetrical diethylaminoethylenediamine, diethylaminoethanol or ethylenediamine; (2) phaeophorbide and asymmetrical diethylaminoethylenediamine; (3) protoporphyrin dimethylester and asymmetrical diethylaminoethylenediamine; (4) haematoporphyrin and diethylaminoethanol; (5) phylloporphyrin or pyrroporphyrin and diethylaminoethanol; (6) the methyl ester of phylloporphyrin or pyrroporphyrin and asymmetrical diethylaminoethylenediamine; (7) the copper salt of methylphaeophorbide and asymmetrical diethylaminoethylenediamine; (8) the iron salt of phylloporphyrin methylester and diethylaminoethanol; (9) phaeophytin and triethanolamine and subsequently heating with copper acetate; (10) chlorin E or rhodin G with diethylaminoethanol; (11) haemin (chlorhaemin of protoporphyrin) or the iron salt of tetramethyl-haematoporphyrin and diethylaminoethanol; (12) the dimethylester of rhodoporphyrin or protoporphyrin and asymmetrical diethylaminoethylenediamine. Specification 304,731, [Class 2 (iii)], is referred to.  The Specification as open to inspection under Sect. 91 also describes the use of basic compounds of the above formula in which R1 and R2 represent alkylamino or halogenalkyl groups or belong to a heterocyclic ring.  Catalysts may be present, such as small quantities of water or of metal salts, e.g. copper or zinc acetate. An example is also included of the interaction of phaeophorbide with diethylaminoethanol.  This subject-matter does not appear in the Specification as accepted.
Patent GB-1183107-A (GB)
Title: Electronic System for Transmission of Two Tone Images
Inventor: BELTRAMI AURELIO
IPC: H04N1/38
Filed: 1967-08-07
Abstract: 1,183,107. Copying telegraphy. A. BELTRAMI. 7 Aug., 1967 [6 Aug., 1966], No. 36136/67. Heading H4F. A method for transmitting a two tone image, e.g. Fig. 2a comprising tone transition points Fig. 2i separating monotonic areas over the normal telephone network, comprises scanning said image with a television type raster to produce video signals, Fig. 2b, generating a pulse, Fig. 2p, marking the end of each line scan, transmitting, Fig. 2m a single detached sinusoidal oscillation, for each of said tone transition points and for each of said generated pulses, the latter oscillations being distinguishable from the former (e.g. in antiphase) and video signals corresponding to said monotonic areas not being transmitted, wherein the exact reproduction of the image at the receiver is made possible by the scanning and reproduction of the image being carried out by means of cathoderay tubes having identical rasters with a two speed line scan, Fig. 2h, comprising low and high speed portions and with frame scans obtained by integration of the end line pulses, the low speed of the line scan being used to scan the tone transition points, and the high speed being used to scan said monotonic areas. By transmitting the tone transition points only and using a high speed scan in between said points, the time needed to scan and reproduce an image is reduced to near that required to scan its transition points only. In the two way system of Fig. 7 each subscriber is provided with a telephone, a flying spot scanner and photoelectric pick-up assembly 1<SP>1</SP> and a cathode-ray tube reproducer L<SP>1</SP>. Each telephone is provided, in conjunction with a switch H, with means whereby an image is transmitted to the other subscriber (position T) or is received therefrom (position R) or only normal sound signals are conveyed (position S). The video signal, Fig. 2b, of the photo-electric pick-up is passed to a circuit C<SP>1</SP> wherein the pulsed oscillations of Fig. 2m are produced. Signals 2d and 2e derived from differentiating the limited video signal, are fed from circuit C<SP>1</SP> to line scan generator B<SP>1</SP> to produce the two speed line scan 2h. A frame scan generator A produces an increase in a step voltage output when a a new end line pulse is counted. Outputs from generators A<SP>1</SP> and B<SP>1</SP> control both the flying spot scanner and the reproducer tube. Received pulsed oscillations, Fig. 3a, are fed to circuit E<SP>1</SP> wherein an intensity modulation signal, Fig. 3h, is produced as well as a line scan signal, Fig. 3g, enabling the reproduction of the image Fig. 3i. Fig. 10 (not shown) shows in detail an arrangement whereby normal telephone conversation takes precedence over image transmission, shuts off the video transmission and lets the speech through. To enable speed to be detected during brief pauses in words &c., a side tone is added to the speech. If the pulses of oscillation are at supersonic frequencies, then simultaneous speech and video may take place.

Title: Apparatus for automatic control of tow take-up means by detecting the amount of tow on conveyor
IPC: B65H63/08
Filed: 1969-07-17
Abstract: 1,254,748. Controlling tow take-up. TEIJIN Ltd. 17 July, 1969 [23 July, 1968], No. 36191/ 69. Heading D1F. Apparatus for the automatic control of the amount of tow T transferred by means of a conveyor 7 comprises a tow detector disposed above the conveyor, the tow detector consisting of a hanging arm 4 mounted on a rotatable means 3, a magnet 5 secured on the hanging arm 4, and a switch 6 to act with the magnet 5, the control being such that the lower end of the hanging arm 4 is pushed up in the tow forwarding direction by the tow T, and the magnet 5 is moved away from the switch 6 which thereby actuates the take-up means. In a preferred embodiment, two tow detectors are positioned above the conveyor 7. In operation, the arm 4 is pushed up by the advancing tow and the switch 6 is on; the arm 4' is then pushed up by the advancing tow and the switch 6' is on. The take-up means does not operate until both switches 6, 6' are on. The take-up means is then operated to take-up at a faster speed than the tow advance. Thus after a time the arm 4' will fall back because of insufficient tow being present and the switch 6' is then off. Since the switch 6 is on the take-up continues until the tow between the arms 4, 4' is taken-up and the arm 4 falls back so that the switch is off. At this point the take-up can stop or be reduced to operate at a slower speed. Several arms may be arranged transversely of the direction of tow advance.

The liquid seal 27 may be in the form of molten material occupying a portion of the annular channel 26. The sealant may be B 2 O 3  or BaO alone or mixed with BaCl 2 , NaF, KCl or NaCl. The reaction vessel may be heated by R.F. coils 28 in the pressurizing atmosphere 29. The reactants may be mixed during synthesis by direct stirring or by cyclically raising and lowering the reaction vessel as in Figs. 7 and 8 (not shown). Nitrides are formed when the pressurizing gas is N 2 . The preparation of polycrystalline ingots of Hg 0À8  Cd 0À2  Te is exemplified.

Abstract: 1,217,806. Tape cassettes. SONY CORP. 18 July, 1969, No. 36271/69. Addition to 1,165,988. Heading G5R. The endless tape cartridge of Specification 1,165,988, intended for use with a reel-to-reel cassette tape recorder, is modified in that the drivable hub 26 and associated pressure roller 27 are movably mounted to facilitate loading to the tape recorder. The hub 26 is journalled via a PTFE sleeve on a stub upstanding from a plate 28 which is loosely journalled in the cassette and which itself carries an integral or other arm 36 supporting the roller 27, and biased inherently and/or by a spring toward the hub. The assembly is located in a well 39 limiting movement. Although the hub 26 is driven for transducing and fast forward transport, no rewind is possible since the reel 22 has a smooth bore and the spindle engaging hub 26 is not driven in the rewind mode, and only one capstan opening 44 is provided to prevent the cassette being inverted. The guide roller 42 is tapered towards its base to re-orient the tape 23 after leaving the reel 22.
