Title: Improvements in combination locks
IPC: E05B37/00
Filed: 1948-08-25
Abstract: 651,173. Permutation locks. BERGGREN, H. E. Aug. 25, 1948, No. 22399. [Class 44] A permutation lock comprises a series of notched slidable tumblers 28-33, Fig. 1, adapted to be displaced in turn by means of a finger dial mechanism to align the notches so as to permit a check rod 43, intersecting the tumblers, to be displaced. The tumblers are mounted in a slidable carrier arranged to move sideways in steps to bring the tumblers into alignment with a single setting member 55. The carrier 35 is guided on a rod 41 and urged to the left by a spring-loaded finger 70. Each tumbler has a part 42 of half width projecting above the carriage which part engages a similar projection 57 on the setting member when the tumbler comes into position in alignment therewith. The setting member is adapted to slide vertically in a guide 56 and is formed with a rack for connection with a pinion 58 attached to the spindle 59 carrying the dial 60, Fig. 2. When the dial is turned, the member 55 moves downwardly and displaces the plunger 28 to align its notch with the rod 43. The dial is returned to the initial position by a spring 67 when released and allows the carriage to advance until the next tumbler projection 42 abuts the projection 57 on the setting member 55. When all the tumblers have been correctly set the rod 43 is freed and allows the carrier to move the last step to position an unlocking rod 51 under the setting member. The end of the rod 43 abuts a face 75 and, sliding relative to the carrier 35 positions a notch opposite the unlocking rod 51 which is in form similar to a tumbler. The rod 51 thus being freed is positioned under the setting member 55 and operation of the dial then, by displacing the rod 51 against the arm 23 of a lever 22 having an arm 21 engaging between pins 19, 20 in the bolt 17, causes retraction of the bolt. The bolt is held retracted by a blade spring 78 engaging in a notch 79. The return spring 67 for the dial is attached at the other end to a pinion 65 operated through a sleeve 64 by a finger stop 63. The pinion engages a rack 72 arranged at about 45 degrees and secured to an arm 76 adapted when the finger piece is rotated to return the tumblers to the initial position and to free the blade spring 78 so that the bolt returns to the locking position under the force of the spring 81. In another form, Fig. 8, the tumblers 84 are arranged radially and the carrier 85 is adapted to move about the centre 86 of the dial spindle. In a modification the setting member and the tumblers are tangential to the dial rack 89. In both cases the check rods 87 are of circular form and cross the tumblers substantially at right angles.

Title: Pulse detection apparatus
IPC: H03K5/153
Filed: 1972-05-12
Abstract: 1390243 Pulse thresholding; telephone systems TELEFONAKTIEBOLAGET L M ERICSSON 12 May 1972 [17 May 1971] 22547/72 Headings H3T and H4K A pulse thresholding circuit, described as used in a narrow band signalling channel in a carrier telephone system, derives the threshold voltage for the leading edge from the differential of the received signal and for the trailing edge from the peak value of the signal. The pulse signal, which, as described, is in the form of an amplitude modulated carrier, is passed through a narrow band filter 10 and it is explained that the slope of the pulse edges is indicative of the pulse amplitude and an indication of the amplitude may therefore be obtained for thresholding the leading edge without the delay resulting from the conventional use of a peak detector. To this end the carrier is detected at 11 and passed at III to one input of a comparator 14 and via a differentiator 12 to the other input II. The peak output from the differentiator occurs at the half-amplitude point and it is arranged that the comparator switches at this level (curves R and P, Fig. 2, not shown). The threshold voltage for the trailing edge of the pulse is derived from a peak detector 16 and attenuator 17. A voltage U o  provides a minimum threshold level. The diodes provide isolation of the threshold channels and the output of the circuit operates a bi-stable circuit 15.

Title: Organic acids of phosphorus and their derivatives
Inventor: LYNCH ERIC ROYLE
IPC: C07F9/6568
Filed: 1961-06-27
Abstract: The invention comprises cyclic phosphinic acids in which the phosphinic phosphorus atom is a member of a 5-, 6- or 7-membered ring which is fused to two aromatic nuclei; their salts, esters, halides, anhydrides, and amides and the corresponding phosphine oxides in which the hydroxyl-group on the P is replaced by hydrogen; and their production by heating an aromatic phosphonic acid having a phosphonic acid group linked (directly or through one or more non-aromatic carbon atoms) to a first aromatic nucleus and a second aromatic nucleus fused or linked (directly or through another atom) to the first, so as to form a bond between the phosphorus atom and a carbon atom of the second aromatic nucleus, e.g. by heating at at least 200 DEG C.  The phosphorus-containing ring may also contain another hetero-atom, e.g. O or S; the aromatic nuclei can be carboxylic, e.g. benzene or naphthalene nucleus, or heterocyclic, e.g. a pyridine, furan or thiophene nucleus.  The various rings may be substituted, e.g. by halogen, alkyl, aryl, alkoxy, aryloxy or nitro groups.  The cyclic phosphinic acids may be derived from phospha-derivatives of polycyclic aromatic compounds such as fluorene, anthracene, phenanthrene, xanthene, acenaphthene, pyracene, chrysene and perylene, e.g. 9-phosphafluorene, -phenanthrene, -anthracene, -xanthene, and -thiaxanthene, 12-phosphanaphthacene and 1,5-diphosphapyracene. Specified acids are 9-hydroxy-9-phosphafluorene-9-oxide, 2-phenyl-9-hydroxy-9,10-dihydro- 9-phosphaanthracene-9-oxide, 2,7-diethyl-9-hydroxy-9,10-dihydro-9-phosphaanthracene-9-oxide, 9-hydroxy-9,10-dihydro-9-phosphaphenanthrene-9-oxide and its 7-methyl-3-nitro-7-methyl- and 3-chloro-6-(p-chlorophenoxy)-derivatives, 9-hydroxy-9-phosphaxanthene-9-oxide, and 1-hydroxy-1-phosphaacenaphthene-1-oxide.  The process described may also produce some of the acid anhydride.  Salts of the acids are obtained from the acid and a base; esters from the acid halide and an alcohol or phenol; or by using a monoester of the phosphonic acid as starting material in the process of the invention; halides by reacting the acid with a halogenating agent, e.g. PBr3 or SO2Cl2; anhydrides by heating the acid, or by reacting a salt of the acid with an acid halide; amides by reacting the halide with an amine; and corresponding phosphine oxides by reducing the acid halide, e.g. with LiAlH4.
