Title: Improvements relating to double-walled tanks
Inventor: ORDELT HERMAN EMIL FERDINAND
IPC: B65D88/76
Filed: 1963-01-31
Abstract: Double walled tanks, e.g. underground petroleum storage tanks, and pipes have the space between the inner and outer walls charged with liquid corrosion protection agent, which may comprise one or more liquids miscible with water and inert to the tank or pipe walls.  For example, polyhydric alcohols, preferably with one or more inorganic inhibitors such as sodium nitrite, alone or in admixture with alkali reacting salts.  Preferably a minor quantity of a vapour phase inhibitor is also included, e.g. morpholine, or dicyclohexyl ammonium nitrite.  The composition is adjusted to give a freezing point value not exceeding -15  DEG C. Preferably the corrosion protection agent, e.g. glycol, contains a substantially saturated solution of sodium nitrite and sodium carbonate with a ratio of NaNO2:Na2CO3 of 3 : 1 to 1 : 1.  In an example the composition consists of an aqueous solution of 25% ethylene glycol, 5% of saturated NaNO2-Na2CO3 sol. and up to 0.1% morpholine or dicyclohexyl ammonium nitrite.  A suitable level indicator, e.g. a manometer, may be provided to indicate the liquid level in the wall space.

Title: Improvements in or relating to time-alarms
IPC: G04F3/08
Filed: 1924-02-16
Abstract: 231,628. Salava, J., and Orlik, L. Feb. 16, 1924, Clock-work actuation.- An electric switch for use in alarm apparatus for signalling the lapse of a predetermined interval of time, comprises a toothed wheel C mounted on a shaft C<1> and having a switch lever K pivoted at K<1> and adapted to co-operate with a stop M<3> mounted on a shaft M and capable of adjustment to the desired extent relativeiy to the switch K by means of a pointer M<5> and a scale P. At the beginning of a time interval the wheel C is thrown into gear with a toothed hour wheel which is driven by a clock and after the predetermined interval the switch K engages the stop M<3> and an alarm circuit is established. Upon continued rotation of the wheel C, the stop M<3> moves the switch K about its pivot K<1> and breaks the alarm circuit at the contacts K<6>, K<7>. Further rotation brings the switch K into engagement with a contact K<3> and a circuit is established to withdraw the wheel C from engagement with the hour wheel. Upon withdrawal, the wheel C and the switch K are returned to their zero positions by springs D, K<5> respectively. In a modification, the stop M<3> has a cam surface which lifts the contacts K<6>, K<7> out from engagement upon continued rotation of the wheel C. In a modified form of contact mechanism, the contact K<6> is normally out of contact with the contact K<1>, but co-operation between the switch K and the stop M<3> moves the contact K<6> over the contact K<7> to complete and then break the alarm circuit. A narrow contact K<7> is employed in order that the alarm may not be unduly prolonged.

Abstract: 776,027. Optical systems. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Feb. 11. 1955 [Feb. 16, 1954], No. 4196/55. Class 97(1) A catoptric device for obtaining a point image of any point on a small threedimensional object by electromagnetic radiation such as X-rays incident on the device at large angles of incidence comprises a pair of concave substantially spherical mirror elements having the same radius of curvature and disposed so that their summit points or poles are substantially coincident in space the planes tangential to each mirror surface at said point of coincidence being perpendicular to each other giving substantial freedom from astigmatism, aramorphosis and distortion. Fig. 2 illustrates the principle of the invention the two mirror surfaces M1, M2 being shown separated. The arrangement is such that light from an object A falls at glancing incidence on the mirror M1 and is reflected thereby to fall at glancing incidence on a perpendicular mirror M2. Aberrations are substantially eliminated when the poles O1 02 of the mirrors are in coincidence as shown at O in Fig. 4. The mirrors are made separately each from a cylindrical block of glass ground on one face into a concave spherical surface and then cut by a plane passing through the pole of the spherical surface at an angle of 45 degrees to the end face of the cylindrical block. The two sections so formed are joined with the section surfaces in contact as shown in Fig. 4, coincidence of the poles being tested by the autocollimator shown. In use the device is mounted for adjustment bv screws K. L, Fig. 5, and the object illuminated by a suitable source of X-ray radiation, is supported on a stage adjustable by knobs G, H, X or Y the image being formed on the screen S. Two devices, one following the other, may be used, the devices being in the "crossed" or "parallel" positions.

Title: Improvements in or relating to telecommunications exchanges
IPC: H04Q3/545
Filed: 1969-01-28
Abstract: 1,210,484. Automatic exchange systems. SIEMENS A.G. 28 Jan., 1969 [1 Feb., 1968], No. 4735/69. Heading H4K. A cyclically scanned storage matrix has sections storing the state of junctor circuits, one code being used in a storage section to indicate that the associated junctor is free and another code, termed the preference code, being used in place of the one code to indicate that one of the junctors that is allotted as next for use, the preference code being transferred to the next storage section with a "free" code whenever a junctor is seized for use. A ferromagnetic core storage matrix has four planes so that each coordinate position as illustrated in Fig. 1 represents a capacity of four bits. The upper group of matrix rows serve groups of 10 subscribers TG, the rows from 11 on serve as stores for individually associated local junctor circuits HUe, the rows from 21 on serve as stores for exchange line circuits AUe, while row 31 and further rows, if required, serves as a store for an operator's position VPl. The first word of each row is examined by setting a scanner AE2 on the first column and stepping a scanner AE1 over a decoder 2 to read out the matrix row by row. For a subscribers' group the first word of each row indicates if any one of the group requires service. For a local junctor or an exchange line circuit the first word of each row indicates idle or busy state and, if idle, the preference code if that circuit is allotted next for use. The scanner AE1 over decoder 1 synchronously interrogates the circuits TG, HUe, AUe and VPl to effect supervision and update the storage matrix. When a local junctor is required in response to a detected calling condition in the line group stores the scan proceeds to the junctor storage rows to find that junctor the store for which contains the preference code indicating its allottment for use. If, as happens when the exchange is first switched on or due to circumstances such as fault, no preference code is written to nominate a junctor, the scanning cycle proceeds and during the next occurring scanning cycle the rules of seizure are changed so as to select that junctor first discovered with an idle code in its store. The event of seizure causes the preference code to be written into the store of the junctor next found to be idle. Seizure of exchange line circuits AUe may be effected using a preference code to pre-allocate a circuit for seizure in the same manner as with local junctors. The same technique may be employed to pre-allocate operators' positions where a group of such positions is provided.
