Patent GB-746485-A (GB)
Title: Improvements in substituted alkylene diamine diacetic acid compounds
Inventor: BERSWORTH FREDERICK CHARLES
Filed: 1953-04-02
Abstract: The invention comprises N,N1-di-(a -butyric acid) ethylene diamine-N,N1-diacetic acid of the formula <FORM:0746485/IV(a)/1> and N,N1-di-alanine trimethylene diamine-N,N1-diacetic acid of the formula <FORM:0746485/IV(a)/2> and the alkali metal, ammonium and amine salts thereof.  The above compounds may be prepared by the general methods disclosed in the parent Specification.  Thus N,N1-di-(a -butyric acid) ethylene diamine N,N1-diacetic acid is obtained by reacting a -aminobutyric acid with ethylene dichloride or dibromide in water, precipitating N,N1-di-(a -butyric acid) ethylene diamine with strong mineral acid, e.g. hydrochloric acid, separating the precipitate, and treating a heated aqueous solution thereof with sodium chloroacetate and sodium hydroxide, carbonate or acetate, added to maintain the pH of the solution at about 10, separating sodium chloride, concentrating, acidifying and finally evaporating the solution to dryness, extracting the residue with methyl alcohol and removing the alcohol from the extract. N,N1-dialanine trimethylene diamine N,N1-diacetic acid is similarly prepared using the sodium salt of alanine and 1,3-trimethylene dichloride or dibromide in place of the a -amino-butyric acid salt and ethylene dichloride or dibromide respectively.  In addition N,N1-di-(a -butyric acid) ethylene diamine N,N1-diacetic acid may be prepared by condensing an alkali metal salt of an a -halo butyric acid with ethylene diamine, or by condensing an alkali metal salt of a -hydroxy butyric acid with ethylene diamine, the secondary amino hydrogens in the product being then replaced with acetic acid residues.  Similarly N,N1 - di - alanine trimethylene diamine-N,N1-diacetic acid may be prepared by reacting an alkali metal salt of either an a -halo propionic acid or a -hydroxy propionic acid with trimethylene diamine and then replacing the secondary amino-hydrogens of the product with acetic acid residues.  The alkali metal, ammonium and amine salts of the two acids may be prepared by reacting the acids with the appropriate base, the reactions being carried out in the manner of an acid-base titration, inflexions in the curve of pH plotted against base addition identifying the formation of the various salts.  The products possess metal ion chelating power in water and organic solvents.

Title: Method and apparatus for steaming textile materials
IPC: D06B19/00
Filed: 1959-03-17
Abstract: <PICT:0873992/IV(c)/1> A method for the continuous steam treatment of textile materials comprises the steps of passing the materials to be treated in the form of a continuous fleece through a chamber in which a steam-containing heated atmosphere is produced, the chamber having an entrance and an exit for the fleece and means for preventing or restricting escape of the steam-containing heated atmoshere at the entrance and exit during passage of the fleece through the chamber, conveying the fleece partly around the periphery of at least one rotary drum sieve disposed within the chamber and drawing the steam-containing heated atmosphere through the fleece into the interior of the drum sieve as the fleece passes partly around the periphery of the drum sieve.  The method of steam treatment may be effected in apparatus comprising a chamber 10 having an exit and an entrance designed to restrict egress of the gas within, means for producing a steam-containing heated atmosphere within the chamber, e.g. spray 18, means for passing textile material to be treated into and out of the chamber, e.g. conveyers 13, 19, rotary sieve drums 11, 12 and at least one fan. The drums 11, 12 may be disposed side-by-side such that the fleece is conveyed in succession partly over one drum and partly under the next adjacent drum.  As shown each drum may contain a stationary cover plate 21 such that any atmosphere drawn from the chamber into drums 11, 12 must pass through the fleece being conveyed thereupon.

A switching device comprises a bead of mercury or other conducting liquid in a channel and movable by pressure exerted thereon by a non - conductive fluid, said pressure being arranged to be generated by applying an external thrust to said fluid. As shown the mercury in one of its positions bridges contacts 1, 2 which may be row and column conductors of a matrix with a plurality of contacts at each cross-point relay (Fig. 1, not shown). The channels may converge from one or both ends and the fixed contacts may be pins 20 (Fig. 6). A plurality of channels 15 are closed at their ends by stop plates 16, 17 of a material through which gas, but not mercury, can pass. Differences in pressure in chambers 23, 24 effects movement of the mercury. The pressure differences can be produced by mechanical, electromagnetic or piezoelectric means and pressure equalization after operation may be due to restricted flow passages alongside the channels (Fig. 2, not shown) or to rectangular or D-section channels (Fig. 5) allowing limited gas venting at the corners. The mercury may be movable past a side channel to which operating pressure is applied to divide the mercury (Figs. 8 to 12, not shown).

Title: Improvements in or relating to devices for producing or restoring synchronism as between the projector and the gramophone of a talking-picture machine
IPC: G03B31/00
Filed: 1929-03-27
Abstract: 331,256. Hepworth, C. M. March 27, 1929. Gramophones associated with kinematographs. - Relates to talking-picture apparatus comprising a synchronously working gramophone and kinematograph, and consists of a particular arrangement of mechanism, embodying epicyclic gearing, whereby errors of phase may be corrected, such errors being caused, for example, by the gramophone needle jumping out of proper position on the record groove. In the system shown in Fig. 1, a gramophone 11 and a kinematograph projector 10 are driven by a common motor 12. The connection between the motor and the projector comprises two shafts 14, 15 coupled by a pair of epicyclic gear trains as shown in Fig. 3. Each of these trains consists of two wheels 19, 20 of slightly different diameter, gearing respectively with coaxial pinions 21, 22 fixed on a shaft 24 which is mounted in a casing 18. Normally the casings 18 rotate solidly with the shafts 14, 15 and the intermediate shaft 23. If, however, it is necessary at any time to speed up or retard the projector relatively to the gramophone, one of the casings 18 is gripped by hand, thus causing the gears associated with that casing to alter the speed of the driven shaft. The two gear trains are similarly constructed, but the wheels are oppositely arranged, so that the effect produced by gripping one casing is the opposite of that produced by holding the other. The invention may be applied, as shown in Fig. 2, to a system in which a speed-equalizing rheostat 26 - - 28 is used in conjunction with two separately driven machines 10, 11, as described in Specification 324,005. A flexible coupling device 29 may also be provided in this arrangement, as described in Specification 325,882.

Title: Paging receiver having a noise-immune verification circuit for disabling battery saving operation
Inventor: OYAGI TAKASHI
IPC: H04B1/16
Filed: 1993-12-23
Abstract: A selective calling radio paging receiver includes a battery saving controller (13) which activates the high power drain unit of the receiver at periodic intervals for allowing the detection of a preamble contained in a received digital paging signal and deactivates it for a period longer than the period of activation for power savings purposes. The power saving is disabled in response to the detection of a preamble for continued power activation to permit a sync detector (8) and an address detector (9) to be operated in succession. A window pulse is generated in synchronism with the clock timing of the received digital signal so that its binary level transition is time coincident with each window pulse. If noise occurs in the received signal, binary level transitions occurs which are out of coincidence with window pulses. The time-coincident binary level transitions and the noncoincident binary level transitions are counted to give first and second counts, respectively. If a valid preamble is lost or corrupted and if the first count is greater than the second, a valid indication of the received signal will be given and power activation is continued to operate the sync and address detectors in succession.
