Title: Improvements in or relating to multiplex telegraph systems
IPC: H04L5/22
Filed: 1922-10-28
Abstract: 207,354. Automatic Telephone Manufacturing Co., Ltd., and Harrison, H. H. Oct. 28, 1922. Multiplex telegraphs; synchronous movements.-In a multiplex system using a code with signal units of unequal length, such as the land line Morse code, the line time is divided equally among the different channels during periods corresponding to the longest period (such as that of the dot) of which the periods of all the signal units are exact multiples. Figs. 3 and 4 show the distributing arrangements for a two-channel system at the transmitting and receiving stations respectively. Fig 1 represents at a and b the letters L and F sent simultaneously over the first and second channels respectively, and at c and d the polarity and duration of the currents sent to line in respect of each channel. In the transmitting distributor, Fig. 3, a contact brush arm CBA sweeps over contact rings R<1> and R<2>, the former being connected to a polarized transmitting relay TR, and the latter being divided into alternate segments a, b connected respectively through the normally closed contacts of the synchronizing switch SS to the transmitter T<1> and T<2>. The corresponding star wheels SW<1> and SW<2> are fixed to the shaft carrying the arm CBA<1>, and this shaft is driven by a phonic wheel or the like. The length of the segments a, b is such that four segments subtend an angle equal to the pitch of the star wheels, this arrangement resulting in the suppression of the second half of each signal component for the first channel, and of the first half of each signal component for the second channel. In the receiving distributor, Fig. 4, a brush arm CBA<1>, moving in synchronism with the arm CBA, sweeps over contact rings R<3> and R<4>, the former being connected to the polarized line relay LR, and the latter being divided into segments a, b connected alternately to polarized storing relays PR<1> and PR<2> controlling receiving apparatus RA<1> and RA<2> corresponding to the two channels. The arm CBA<1> is driven by a phonic wheel PW controlled by a Gulstad relay vibrator GR of which the correcting upper winding is traversed by a momentary current at each reverse of the line relay LR, the flow of continuous current being prevented by a condenser c<1>. The speed of vibration is initially adjusted by varying the values of resistances r<1>, r<2> and of a condenser c<2> when the switch SS is in position to connect positive and negative current alternately over the line, and phase adjustment is effected by rotating the divided ring or the brush arm. In a modification, the star-wheels are rigidly connected to ratchet wheels which have twice as many teeth as the star wheels and are stepped by magnets controlled by a second brush on the arm CBA connecting an earthed ring with a ring divided into segments equal in number to the segments of ring R<2>, these segments being alternately blank and connected to the magnets.

Filed: 1926-11-29
Abstract: 272,165. Heberlein & Co., Akt.-Ges. June 5, 1926, [Convention date]. Yarns, treating with liquids.-The treatment of yarns &c. composed of vegetable or artificial fibres, with a halogen compound. of phosphorus, is applied locally for the purpose of enabling, differential effects to be produced. Thus, the material may be printed with a reservethickening, and then subsequently in combination with previous or subsequent treatment with alkali, or even without such treatment, subjected to the action of a solution of a halogen compound of phosphorus, either alone or in the presence of alkali; alternatively, alkali, with or without a dyestuff, may be added to the thickening, and in this case the printed portions react more readily with the phosphorus compound than do the unprinted portions. In examples, mercerized cotton yarn is printed with a gum thickening, then passed through an adcoholic solution of caustic soda, and finally treated with a solution of phosphorus oxychloride in toluene; a cotton-viscose silk fabric is printed with a reserve, and then treated with a solution of phosphorus oxychloride in benzene; cotton fabric is printed with a thickening containing caustic soda, and then drawn through a solution of phosphorus oxychloride in xylene.

Abstract: 1,021,570. Temperature alarms. SPECIALTIES DEVELOPMENT CORPORATION. July 31, 1964, No. 30298/64. Heading G4N. [Also in Divisions H2 and H3] In a temperature alarm of the type in which an abnormal temperature varies the resistance of a detector element, false alarms due to moisture across the electrodes of the detector element are obviated by ensuring that the voltage across the element, when the abnormal resistance value is approached, is less than about 1À2 V. As described, resistors 40, 42, 45 and a detector cable 19<SP>1</SP> form a bridge. As the abnormal temperature is approached transistor 46 is cut off switching on transistor 54 to operate alarm relay 60. The supply 41 is 10 V., resistor 40 is 10,000 ohms and detector 191 about 700 ohms in the abnormal condition, giving a potential of about 0À7 voltas across the detector. It is stated that potentials of this order cause the moisture to polarize and thus make the leakage resistance Rs high.

As shown the control signal is provided by the output of a digital multi-plexer 14 and digital-toanalogue converter 13, the measurement input 15 stemming from an analogue-to-digital converter 17 and another multi-plexer 18 which switches sequentially between inputs A and B. The reference signal 16 and the switching of the multi-plexers 14, 18 is achieved by a squarewave generator 26 and train of frequency-dividers 21-25. The input 8 is thus provided in sequence, as shown in Fig. 9, by (i) four different reference signals (ii) measurement signal A (iii) a repeat of the four different reference signals, and (iv) measurement signal B. A generator 29 may be used to impose a high frequency signal on signal B in order that the records of signals A and B can be distinguished. In an alternative arrangement Fig. 10 (not shown) an array of multi-plexers (33-35) is used to provide the reference signal by appropriate sequential switching between four analogue reference inputs (A-D).

Abstract: 262,437. Siemens - Schuckertwerke, Ges. Dec. 4, 1925, [Convention date]. Motor power plant.-A high pressure steam boiler is cooled when the firing is stopped and the steam valve closed by passing water through the boiler into a hot water accumulator. Steam from the accumulator is used for driving an engine, say the pump engine, surplus steam being led into a steam regenerative accumulator. At restarting, the water in the hot-water accumulator is circulated through the boiler until the desired temperature and pressure are reached. Steam from a boiler 1 is supplied through a pipe 3 to an engine 4, exhausting into a low-pressure pipe line 7, from which steam is supplied to condensing engines 9, 10. The two-stage engine 10 drives an electric generator supplying current to the motors of the feed pumps 17, 20. When the main steam valve 29 is closed, the engine 10 is driven by steam from a. hot-water accumulator 19, which receives the cooling water forced through the boiler by the feed-pumps. A steam regenerative accumulator 26 receives steam from the pipe line 7. and supplies steam through a valve 33, controlled by the pressure in the pipe line 7, to the second stage of the engine 10. Upon restarting, the water outlet valve 32 of the accumulator 19 is opened, and the pump 20 is started to circulate water from the accumulator through the boiler. Subsequently the valve 32 is closed, and the feed-valve 38 and steam valves 29 are opened.

Title: Compositions of insecticidal and acaricidal activity containing organic halides
Inventor: BARBER HARRY JAMES
Filed: 1950-12-13
Abstract: Insecticidal, acaricidal and fungicidal compositions comprise new organic halides of general formula R.X.CH3'n. Cl-n where X represents an oxygen or sulphur atom, n is either 2 or 3 and R represents a phenyl radical containing at least one chlorine substituent, and which may further contain methyl groups; together with a diluent. The diluent may be a liquid, e.g. water, in which case the formulation may incorporate a solvent or solid carrier, together with a wetting, dispersing or emulsifying agent, with or without stabilisers or other additives.  The halides may be employed in spray formulations of the "wettable powder" type. In association with e.g. kaolin, gypsum or chalk, they may be used as dusting agents or as aerosols.  Some of the halides appear to act as fumigants.  In examples: (1) 4-chlorophenoxythiomethotrichloride is formulated into a self-emulsifying composition with xylene, mineral oil and non-ionic emulsifying agents.  2 : 4-dichlorophenoxymethotrichloride is formulated likewise.  (2) 4-chlorophenoxymethotrichloride is formulated into a wettable powder by spraying it on to a diatomaceous earth and treating the product with an ionic wetting agent.  (3) 4-chlorophenoxy methotrichloride is impregnated in brown paper, which then serves to produce an insecticidally active atmosphere. Specifications 712,478 and 714,410, [both in Group IV(b)], (relating to the preparation of the organic halides) are referred to.
