Patent GB-1099512-A (GB)
Title: Data transmission system
Inventor: HERSHEY HAROLD JACOB
IPC: H04M1/278
Filed: 1965-03-22
Abstract: 1,099,512. Repertory dialler. WESTERN ELECTRIC CO. Inc. March 22, 1965 [March 20, 1964], No. 12017/65. Heading H4K. [Also in Division H2] A repertory dialler, whieh transmits impulsetrains according to digits encoded upon successive rows of a punched card, contains a programme controlled switching matrix whose initial setting for each digit by the punched card determines the number of impulses transmitted by fixing the position in the programme sequence at which impulse transmission is stopped. The card after being inserted into the dialler is ejected bit by bit as dialling proceeds: each row of punched holes corresponding to a digit and being mechanically sensed in turn to set particular pairs of make and break contacts A 1 A 2  to G 1 G 2  of a switching matrix 220 (Fig. 16). The remaining contacts A to F are provided by spring contacts co-operating with tracks upon a printed circuit disc (Fig. 12) which for each digit row sensed rotates from an initial position to operate the make contacts according to the programme provided by the printed pattern. Rotation continues until the occurrence of a path through the matrix operates relay K to remove the drive from the disc. Impulse springs co-operate with tracks P 1 P 2  to transmit a number of impulses according to the extent of rotation which is dependent upon the initial setting of the matrix by the particular row of the punched card. The disc is returned to its rest position by a spring during which time the relay SH short circuits the line. The card upon insertion into the dialler winds a spring which effects its ejection during dialling: the movement being controlled by relay K and an escapement-pawl mechanism. Such movement takes place in two steps, the first of which breaks all the code contacts A 1 A 2  to G 1 G 2  by suspending the mechanical sensing probes between rows and the second step of which places the probes in the next digit code row. For use with a PBX or for use with numbers with fewer digits than 14, a position in each row of punched holes is perforated to effect a stop. Thus when, for a PBX subscriber, 9 is first dialled for an outside line it is necessary for the transmitter to halt until the necessary dialling tone is received. On receipt of dialling tone the start button is again pressed to continue transmission.

Title: Manufacture of water-soluble sulphochloracetic acid ester salts of leuco vat dyestuffs
IPC: C09B9/02
Filed: 1953-04-30
Abstract: The invention comprises sulphochloracetic acid ester salts of leuco vat dyes which are made by reacting the leuco compound of a vat dye with a halide of sulphochloracetic acid in presence of a tertiary base, and converting the compound obtained to a stable water-soluble salt.  The dyestuff may be simultaneously reduced and esterified in presence of a metal.  In examples, the following are heated in pyridine with iron powder, sulphochloracetic acid, and p-toluene sulphochloride, while passing carbon dioxide through the mixture:- (1) Bz2 : Bz21 - dimethoxydibenzanthrone (phosgene may replace the p-toluene sulphochloride), (2) 5.51.7.11 - tetrabromindigo, (3) dibrom - dibenzpyrenequinone, (4) 4.41-dimethyl - 6.61 - dichloro - thioindigo, (5) the alkaline condensation product of Bz- 1 - (a-anthraquinonyl) - aminobenzanthrone.  Also in examples, the already-formed leuco compound of 5.51 - dichloro - 7.71 - dimethyl thioindigo is reacted with sulphochloracetic acid and p-toluenesulphochloride in pyridine. The product in each case is converted to the sodium salt by treatment with sodium carbonate or bicarbonate solution and then salting out.  Other vat dyes are listed.  Specifications 186,051 [Class I] 202,630, 202,632 [both in Class 2(iii)] 220,120 [Class 77] 251,491, 297,133.  330,579 [all in Class 2(iii)], 497,327, 585,106 [both in Group IV] and 610,117 are referred to.

Filed: 1975-03-24
Abstract: 1490431 Fertile period or pregnancy test  implement ALZA CORP 24 March 1975 12163/75 Heading G1B A fertile period or pregnancy test implement comprises an absorbent carrier containing an acid pH buffer and an N-acetyl-beta-d glucosaminide, the glucosaminide reacting with enhanced levels of a glucosaminidase in a female biological liquid such as saliva at the acid pH to give a reaction product which when the female is fertile or not pregnant has a distinct colour at another pH. The absorbent carrier material may be a filter paper, cellulose strip, wood strip, felt, porous ceramic strip, velour, cloth. The glucosaminide may be a colourless phenolic (aryl hydroxy) derivative which reacts at an acid pH (4-5) to form a phenol which has a  colour at an alkaline pH (8-11). In use, the test implement may be touched with saliva, then after 20-40 minutes the implement is wetted with for example pH 9-11 buffer and inspected for colour change. The test may be carried out in solution using the glucosaminide dissolved in the acid buffer solution.
