Title: Control unit for controlling printing head of a series printer
IPC: B41J19/18
Filed: 1973-05-23
Abstract: 1422984 Control of printers SOC LAGOBAX 23 May 1973 [25 May 1972] 24729/73 Heading G4H A print head control unit comprises a buffer 301, means for returning the head to the beginning of a line when the characters in the buffer have been printed, and means for rapidly returning the head to the next printing position along the line when new characters have been stored in the buffer. The addresses in the buffer of the last character to be entered and the next character to be printed are recorded in counters AE, AS which are incremented by 1 at the time of each character input and output respectively on lines 305, 306. A comparator 304 compares the addresses to produce two signals OKS (print next character) or OKE (input new character). The print head position is indicated by the count accumulated in a counter 310 which is incremented as the print head moves from character to character. When AR = AS (i.e. all the characters have been printed) the contents of 310 are transferred to a counter register 312 while the print head is returned to the beginning of the line. New characters are stored in 301, and the print head advanced along the line, decrementing 312 as it does so, until the last printed position is reached; a decoding circuit 313 detects a count of zero in 311, and printing is resumed. Provision is made (314-319) for recognizing and performing functions such as carriage return and tabulation. The printer may receive data from a keyboard 403, Figs. 4, 5 (not shown), and/or from a remote computer connected thereto by modems (404-406).

J. ; 1601, Sycamore Street, Haddon Heights, New Jersey, U.S.A.) Sept. 8, 1932, No. 25080. Convention date, Sept. 18, 1931. [Classes 40 (iii) and 40 (v).l In a television system in which synchronizing signals of greater amplitude than the peak picture signals are transmitted over the same channel and in which the synchronizing signals are, at the receiver, separated from the picture signals by amplitude selection, the transmitter includes a control arrangement by which the general level of the picture signals is prevented from reaching a value such that the peak picture signals may be of such an amplitude as to cause faulty operation of the synchronizing means at the receiver. In the transmission of a kinema film 12 scanned by a disc 11 associated with a light source 15 and a photo-electric cell 16 to generate the synchronizing impulses. The output from the photo-electric cell 13 generating the picture signals is fed through amplifiers 14, 18 to a wireless transmitter and to an amplifier 25 which controls a valve 26 operating on the lower part of its characteristic. When a light portion of the film is being scanned an increased voltage on the grid of the valve 26 increases its plate current and the grid of a valve 27, operating on the upper portion of its characteristic is made more negative. The reduction in the plate current of the valve 27 reduces the voltage in the circuit of the photoelectric cell 13 with consequent decrease in the output from the cell 13 applied to the amplifier 14. The values of the resistances 28, 29 and capacities 30, 31 are adjusted so that the control arrangement is not responsive to picture signals representing a line or several lines, but only to those constituting at least one picture frame. Specification 398,242 is referred to.

Title: Process for preparing ethane-1-hydroxy-1,1-diphosphonic acid
IPC: C07F9/38
Filed: 1967-05-31
Abstract: 1,145,608. Preparing ethane-1-hydroxy-1,1- diphosphonic acid. PROCTER & GAMBLE CO. 31 May, 1967 [31 May, 1966], No. 25128/67. Addition to 1,131,916. Heading C2C. Ethane - 1 - hydroxy - 1,1 - diphosphonic acid is obtained by (1) reacting an anhydride of phosphorous acid which has an anhydrising power (as defined below) equal to or greater than 1 with a stoichiometric excess of acetic acid in the absence of an organic solvent to form a reaction mixture containing phosphite intermediate compounds; (2) heating said reaction mixture to convert the phosphite intermediate compounds to compounds containing carbon atoms bonded directly to phosphorus atoms; and (3) treating the reaction mixture with water so as to hydrolyse said compounds containing carbon atoms bonded directly to phosphorus atoms to form ethane-1- hydroxy-1,1-diphosphonic acid. The anhydrizing power is defined as the number of anhydride (P-O-P) links required to form one mole of ethane-1-hydroxy-1,1-diphosphonic acid. The preferred anhydride is P 4 O 6  which has an anhydrising power of 3. The acetic acid is used in excess and up to 100 moles or more of the acid may be used per mole of the phosphorous acid anhydride, the more preferred range being from 2: 1 to 20: 1. The anhydride may be formed in situ e.g. by starting with elemental phosphorus and the reaction in step (2) is generally effected by heating at between 90‹ and 150‹ C. for a period of from 3 minutes to 4 hours. The hydrolysis step is preferably carried out with an excess of water and may be carried out at room temperature or higher, usually at between 90‹ C. and 170‹ C. If desired the hydrolysis may be carried out in more than one stage, e.g. by first adding less than the theoretical amount of water and then adding the balance or excess water in a subsequent step. A cyclic by-product condensate of the formula may be formed in the main reaction step and this may be crystallized out, filtered off and subsequently hydrolysed to form ethane-1-hydroxy- 1,1-diphosphonic acid. The acetic acid remaining in the final reaction mixture after hydrolysis can be removed by steam distillation using superheated steam, e.g. at 130-150‹ C. When P 4 O 6  is used as the anhydride it may be prepared by oxidation of yellow phosphorus using a dry mixture of oxygen and nitrogen and a detailed preparation of this type is given. The free ethane - 1 - hydroxy - 1,1 - diphosphonic acid can be recovered by extraction with a mixture of water and a water-immiscible organic solvent especially chloroform and is recovered from the aqueous phase. The free acid can be converted to any desired salt by adding a base, e.g. sodium or potassium hydroxide.
