Title: Automatic control means for machine tools in production lines
IPC: G05B19/04
Filed: 1954-05-11
Abstract: 754,163. Machine-tool details. CROSS CO. May 11, 1954 [July 8, 1953], No. 13775/54. Class 83 (3). Automatic control means for a pair of machine tools which respectively perform the same operation on a workpiece comprises means for determining the number of machining operations carried out by each'machine, means for maintaining one of the machines inoperative while the other is operative and means, under the control of said operation-determining means, for automatically bringing the inoperative machine into operation and simultaneously rendering the operative machine inoperative when the latter has carried out a predetermined number of machining operations. A production line 10, Fig. 1, includes a pair of machine tools 16, 18, which perform the same operation, one of which serves as a standby when the other is out of action for maintenance or change of tools. Electric power is delivered to a controlunit 26 and thence transmitted to the machines 16, 18. The current then flows to a programmecontrol or memory-unit 34 which is preferably as described in Specification 753,916, but may comprise known devices ' such as punched cards, magnetic tape or film, magnetic drums or discs or dialectric-storage devices. Current is finally returned along the line 40 to the control-unit 26. At the start of an operation, indicators 42, 48, Fig. 2, of the type described in the above Specification, are set to the estimated life of tools in the machines 16, 18 respectively, a cycle start-switch 100 is closed and the selected machine carries out the pre-set number of cycles; The machine is then automatically stopped by the control means and the other machine started. Electrical arrangements.-For machine 18, closure of the cycle start-switch 100 completes a circuit through the switch, the current flowing through line 158, switch 94 and lines 160, 162 to energize control-relay. 68 to close switch 80. When the latter is closed a circuit is established including line 164, switch 80, line 166, machine. operating circuit 63 and line 168. Flow of current through circuit 63 causes the cutting- head of the machine to advance for. machining. When the cutter-head reaches the desired forward limit a stop switch 62 -is closed. This switch, when closed, completes a circuit including line 1.70, switch 62, lines' 172, 174, control-relay 70 and line 176 to energize the control-relay and close switch 87. The latter completes circuit 178, 180 and circuit 63 to retract, the cutter-head. Closure of switch 62 also completes a circuit through lines 182, switch 96 and line 184 through a master timermotor 56 (see above Specification). The latter then operates to close switch 58 for a short interval, thus allowing motor 50 to run for a short time by'closing circuit including line 184, switch 98, lines 188, 190 and motor 50. The latter runs for a short time to index the indicator pointer 48 to register another cycle of the machine and show how many cycles remain before automatic switch-off will occur.

Title: Data-transmission-reception systems
IPC: H04J3/16
Filed: 1971-05-07
Abstract: 1349964 Automatic exchange systems R PERON 7 May 1971 [8 May 1970] 13817/71 Heading H4K In a system for transmitting data between subscribers on different T.D.M. exchanges in which the transmission bandwidth requires a plurality of time channels for a single direction of transmission and in which the time channels are liable due to intermediate storage in interhighway switching to have different transmission times, test words transmitted over the channels prior to the data are used to determine the number of cycles of delay of each channel, and a shift register arrangement at the receiving end uses this information to reassemble elements of data words received over the channels. As described four time slots are required on each highway for each direction of transmission. At the exchange associated with the receiving station a group of shift registers is provided for each of the time channels so provided. There are at most four exchanges involved in any call and each group comprises four shift registers/connected in series. Data can be entered into any one register and be shifted towards the output through any subsequent registers to provide a delay of a corresponding number of exchange cycles. Each shift register group passes the data elements received over the associated channel adding further delay if necessary to bring the total transmission delay of each channel up to four exchange cycles so that the elements in different channels are time aligned for re-assembly into complete data words. To determine the further delays necessary for each channel, a test or synchronizing transmission in the form of two reset words and four identical test words is transmitted over each channel and stops counters associated with those channels, and driven by exchange cycle clock pulses, individually at counts corresponding to the delays in each channel. Thus each counter becomes set to the number of cycles of delay existing in the corresponding channel and routes information from that channel into that shift register of the associated group that corresponds to that stage. The stage used as an input determines the further delay necessary to bring that channel into alignment with the others. The return path uses a different pluraality of time channels. If an error is detected transmission of further data is inhibited and an error signal is transmitted to the other station.

Title: Process for the production of substituted carboxylic acids
IPC: C07C309/58
Filed: 1952-06-04
Abstract: Substituted aromatic carboxylic acids or ammonium salts thereof are made by reacting at elevated temperature and pressure, an aromatic compound containing a -CH2Cl or -CHCl2 group and a neutralized sulphonic acid group, with an aqueous solution of an ammonium polysulphide or with sulphur and an aqueous solution of ammonia. Thus the ammonium salt of benzoic acid-p-sodium sulphonate may be obtained from p-toluene-sodium sulphonate after chlorination, the benzyl chloride- and benzal chloride-p-sodium sulphonates being converted as above and the benzotrichloride - p - sodium sulphonate being hydrolysed during the reaction.  Residual p-toluene-sodium sulphonate from the chlorination step remains unchanged.  Preferably 1.3-1.5 gram atoms of chlorine are introduced per mol. of starting material. o-Toluene-sodium sulphonate may also be treated.  The sulphonic acid group is preferably neutralized by an ammonium radicle or an alkali metal.  In examples: (1) p-toluene-sodium sulphonate is chlorinated whilst irradiated and the product treated with sulphur and aqueous ammonia in an autoclave at 180 DEG  C. to yield the ammonium salt of benzoic acid-p-sodium sulphonate; and (2) chlorinated o-toluene-sodium sulphonate is treated as in the latter part of (1) to yield the ammonium salt of benzoic acid-o-sodium sulphonate.  In both examples the corresponding free acids may be obtained on acidification.
