Title: Timing device for high speed printers
IPC: G06K15/08
Filed: 1970-06-01
Abstract: 1308964 Timing operations in electric circuits HONEYWELL INFORMATION SYSTEMS ITALIA SpA 1 June 1970 [30 May 1969] 26349/70 Heading G3T  Relates to a timing arrangement particularly for high speed printers used in digital data handling units, the type carrying member being a rotary ring or drum 1, Fig.1, on which at least one series of printing characters, Fig.3, are arranged circumferentially and in relief and pass a printing hammer 7 at definite time instants when the drum is driven at constant speed. The timing arrangement includes a timing disc 3 on the drum shaft and having notches coinciding with characters on the drum, as illustrated, Fig.2, and which cooperate with a pick up 10 which produces a signal which a pulse is produced on the detection of each successive notch. A predetermined number of pulses counted signifies that a particular character is opposite the hammer which is actuated accordingly. In addition the disc has a sector A without a notch which causes the imitiation of a turn pulse signifying the end of a sequence and beginning of the next sequence of characters. This may alsoindicate one revolution of the drum if there is only one series of characters on a circumference thereof as in, Fig.2. In operation, a sine wave signal from the pickup 10 is converted to a train of square pulses by an amplifier 13 and applied to an F-F (flip-flop) 15 which sends a series of "character" pulses to a unit 17. This unit comprises a binary counter and a comparator. The comparatorproduces an output at 18 to operate the electromagnetic hammer 7 thus pressing an ink ribbon 5 and paper 6 against the appropriate character on the drum, when a code combination defining a character to be printed and commanded at input 23, agrees with a code combination derived by the binary counter in unit 17 from the character pulses at input 16. The output of F-F 15 is also applied to a F-F 19 which has a time constant T. If the interval between successive character pulses exceeds T, such as when the notchless sector meets thepick-up, F-F 19 is reset to a reduced output voltage level which causes a 'turn' pulse output from a F-F 21. The turn pulse resets the binary counter to its initial condition. In Fig.8 (not shown), a tachogenerator is coupled to the drum and disc drive motor and its output changes the time constant of the F-F 19 whereby the character pulse period. P andperiod T of 19, always have the same ratio irrespective of speed. The disc 3 may form part of the drum, or the pick-up may be arranged to sense the characters on the drum, or ferro-magnetic inserts may be provided between successive characters. A character may be printed e.g. "O" coincident with the sensing of the notchless sector.

Patent GB-891087-A (GB)
Title: Silalkyltin compounds
IPC: C07F7/08
Filed: 1959-08-10
Abstract: The invention comprises silalkyl tin compounds of the general formula <FORM:0891087/IV (a)/1> where R is a monovalent hydrocarbon radical, R1 is an alkyl or phenyl radical, Y is hydrogen or an alkoxy radical, Z is hydrogen or methyl, x is 1, 2 or 3, m is 0 or 1, and n is 0 or is 1 when m is 1.  Thus the groups linking the silicon to the tin are -CH2-, -CH2CH2-, -(CH2)3- or -CH2CH(CH3)CH2-.  They may be prepared by reacting the Grignard compounds HR2SiCH2-(CHZ)n(CH2)mMgCl (or bromid or iodide) with organo-tin halides R1rSnHal4-x.  The compounds in which Y is alkoxy are prepared from these hydrogen compounds by reacting with alcohol in the presence of sodium. Examples of the radical R include alkyl, aryl, aralkyl, alkaryl, alkenyl, alkynyl and cycloaliphatic.  The preferred R1 radicals are C1-4 alkyls.  The examples describe the preparation of the following compounds: (1) (HMe2SiCH2)2-SnMe2 and (HPhMeSiCH2)2SnMe2; (2) (HMe2SiCH2)2SnBu2; (3) (Me2EtOSiCH2)2-SnBu2; (4) [HMe2Si(CH2)3]2SnMe2; (5) HMe2SiCH2SnBu3 and Me2EtOSiCH2SnBu3; (6) (HMe2SiCH2CHMeCH2)2SnMe2 and (HMe2SiCH2CHMeCH2)SnBu3; (7) (HMe2-SiCH2)2SnPh2 and (HMe2SiCH2)3SnBu. The compounds may be hydrolyzed to polysiloxanes or reacted with unsaturated compounds as described in Specifications 891,088 and 891,089.  The compounds in which R1 is butyl are anti-microbic, anti-fungal and anti-mildew.  The Grignard compounds HR2SiCH2(CHZ)n-(CH2)mMgCl are prepared by diluting HR2Si-CH2(CHZ)n(CH2)mCl with diethyl ether or tetrahydrofuran and contacting with magnesium shavings. These haloalkyl compounds are themselves prepared by reducing the corresponding halosilane, e.g. ClCH2(CHZ)n(CH2)mSiR2Cl, with LiAlH4.  The latter intermediates may be prepared by halogenating MeSiCl3 and replacing two of the Si-bonded halogen atoms by conventional Grignard; or, when longer alkylene chains are required, reacting allyl, methallyl or vinyl chloride with R2HSiCl &c.
