Abstract: 1,160,856. Mechanical seals. DURAMETALLIC CORP. 19 April, 1968 [10 May, 1967] No. 18723/68. Heading F2B. A mechanical seal for the rotatable shaft of a pump, autoclave or turbine comprises rotatable and fixed sealing members 36, 19 enclosed by a jacket 47 which is rotatable with the shaft and forms a chamber 49 within which is located a ring 51 adjacent a passageway 53 extending radially outwardly of the chamber, the rotation of the shaft causing the ring to be centrifugally forced against the walls of the passageway so as to seal the chamber. The rotatable member 36 is driven through a member 34 by pins 33 and is urged axially into sealing engagement by springs 37 and fluid pressure. The fixed member 19 may be made of carbon and is provided with passageways 28, 29 for circulating coolant supplied through an inlet 24 and discharged through an outlet 26. During rotation of the shaft the ring 51 seals the passage 53 by both centrifugal force and the pressure of the coolant and when the shaft is stationary the pressure of the coolant filling the chamber 49 is sufficient to force the ring into sealing engagement with the passage. Coolant is also circulated through the seal housing 14.

Title: N-alkyl and n-alkenyl derivatives of 3-aza-bicyclo (3-3-1) nonane
IPC: C07D221/22
Filed: 1957-06-14
Abstract: The invention comprises compounds of the general formula <FORM:0824140/IV (b)/1> where R is an alkyl or alkenyl group containing up to 3 carbon atoms, and acid addition salts thereof and the preparation thereof (1) by alkylation or alkenylation of 3-aza-bicyclo[3-3-1]-nonane with an alkyl or alkenyl halide dissolved in an inert solvent, and, if desired, in the presence of a hydrogen halide acceptor, and optionally converting the nonane base thus obtained into an acid addition salt; (2) (wherein R is a methyl group only) by methylation with formic acid and formaldehyde; and (3) (wherein R is an alkyl group only) by reacting hexahydro-iso-phthalic acid with a primary amine R1-NH2 (where R1 is an alkyl group containing 1-3 carbon atoms) at a high temperature, and reducing the N-alkyl hexahydro-iso-phthalimide thus formed with lithium aluminium hydride.  In an example, methylamine is passed through molten hexahydro-iso-phthalic acid (any bis-methylamide distilling off with the water formed being returned to the reaction mixture) to give, on distillation, N-methyl hexahydro-iso-phthalimide, which is reduced with lithium aluminium hydride to N-methyl-3 - aza - bicyclo - [3-3-1] - nonane, (the picrate, perchlorate, hydrobromide and acid maleate are also prepared).  In further examples, compounds of the invention wherein R is methyl are prepared by methylation of 3-aza-bicyclo-[3-3-1]-nonane with formic acid and formalin, and wherein R is isopropyl, allyl and ethyl, by reacting the nonane base with the corresponding alkyl or alkenyl bromide or iodide either alone or in the presence of pyridine.  Salts, including the hydrobromide, picrate, and acid maleate, are also prepared.

Abstract: 1404515 Securing ends of coaxial cables AMP Inc 19 April 1973 [12 May 1972] 18976/73 Heading H2E In a connector for terminating the aluminium outer conductor 16 of a semi-rigid coaxial cable 12, an outer ferrule 28, having means for gripping the conductor 16, is received within a bush 26, and an inner ferrule 60 is received within a bush 62, with interengaging means for drawing together the bushes 26, 62, in such a manner that the outer conductor 16 becomes secured between the ferrules 28 and 60. A ring 30, having inward-facing spring teeth (52), Fig. 2 (not shown), and trapped in a recess 51, may serve as the means for gripping conductor 16 during an initial assembly stage, when the relative location of ferrules 28, 60 is temporarily set by a gauge sleeve 32, Fig. 4. The interengaging means may comprise mating screw threads, and when the bushes 26, 62 are screwed together, having discarded sleeve 32, the inner ferrule 60 is caused to enter and expand conductor 16, resulting also in deformation of the outer ferrule, 44, Fig. 5, into an enlarged bore portion 40 provided in bush 26. This metal-to-metal seal, together with 0-ring seals 80, 72, prevents entry of water into the cable. After assembly, the bore diameters of members 16, 60 and 62 are substantially equal, thereby minimizing r.f. electrical reflections. The inner conductor 18, unbroken through this coupling, may be terminated within a distribution box (10), Fig. 1 (not shown), into which the bush 62 may be mounted, and which may form part of a cable television signal distribution system.

Abstract: 836,331. Television. FERNSEH G.m.b.H. June 20, 1958 [June 22, 1957], No. 19809/58. Drawings to Specification. Class 40 (3). In a method of measuring the frequency response characteristic of a preamplifier associated with a television camera tube with the aid of an input sinusoidal test signal varying cyclically in frequency over a range to be investigated, the amplifier output being displayed by an oscilloscope deflected cyclically in synchronism with the frequency variation of the test signal, the difficulty of matching the output impedance of the test signal generator to the input impedance of the preamplifier is avoided by causing the photo-sensitive member of the camera tube to be illuminated uniformly, if at all, and applying the test signal to the tube in such manner that the tube functions to furnish the test signal input for the amplifier. In the case of a supericonoscope camera tube, the photo-cathode is not illuminated and the test signal is applied to modulate the intensity of the scanning beam which is otherwise adjusted to a value that yields a minimum spurious signal. In the case of an imageorthicon tube, the test signal is applied to the mesh electrode adjacent the target electrode. In the case of a vidicon camera tube, the photocathode is illuminated uniformly and the test signal is applied to modulate the scanning beam which is adjusted to a value such that the storage target is never completely changed. Preferably it is arranged that the test signal is applied to the camera tube during a part only of each frame period, suitably only during the scanning of a central region of the target. A camera adapted to facilitate the measurement includes an input socket for the test signal and a change-over switch arranged to connect the appropriate tube electrode either to the blanking amplifier or the test socket.

In a digital transmission system the time of occurrence of a received pulse is recorded and when a subsequently received pulse is received the time difference between the pulses is determined.  In one embodiment the time of occurrence of the Start bit of a telegraph signal is recorded in a store. The stored time is subtracted from the time of occurrence of each subsequent change in level in the signal, and from the result is subtracted a time equal to a multiple of the theoretical signal element duration. The resultant signal represents the amount that the change in level differs from its theoretical position, and if this amount is less than half an element in duration, a counter records the number of elements received and a store stores the received elements.  In a second embodiment the time of occurrence of a received dialling pulse is stored in a first store, and the time of the next pulse in a second store. If the time difference is within the correct limits the second store is read out to the first, for subtraction from the time of the next pulse, and a counter is incremented.
