Abstract: 1,010,686. Releasable fastenings. R. J. EMERY. July 29, 1964 [May 11, 1964], No. 19462/64. Heading E2A. A jamming cleat has a groove opening out of one side and extending over the whole length of the cleat the groove having opposed internal faces which converge towards the bottom of the groove and ridges on each face, the ridges on both faces being inclined to the base of the groove upwardly from one end of the groove. In Figs. 1 and 2 the cleat is of truncated conical form and is intended for use as a knob for the pull cord of for example an electric light switch. The ridges are inclined at an angle of 45 degrees to the axis 16 of the cleat and as shown each ridge on one face of the groove is aligned with a ridge on the opposite face of the groove. In a modification, however, the ridges on opposite faces are staggered relative to each other. The angle in either form can be varied from 45 degrees. As shown also the ridges are straight but in a modification they can be curved. In another modification they can have one or more angles in their length. In cross-section the ridges are triangular or arcuate. In another construction, Fig. 10, the cleat is basically a rectilinear block with a single groove having ridges of any of the forms described above. The block is provided with two lugs haying bores 20 so that the cleat can swivel about a bar rigidly fixed to a supporting structure. In another construction a plurality of parallel grooves are provided; each groove being provided with any of the forms of ridges described above and being intended to be screwed to a support. Various polygonal blocks each having a plurality of parallel slots in two or more faces are disclosed. In another construction, the cleat is made in three parts which are bolted together. The groove or grooves of any form instead of being of the shape with inclined walls shown can be modified so that near its bottom the walls are parallel.

Title: Preparation of improved tetracycline-metaphosphate complexes
IPC: C07F9/08
Filed: 1958-06-18
Abstract: The invention relates to a tetracycline metaphosphate complex having a solubility in water in excess of 500 micrograms per mil water.  It is stable in water and in organic liquids such as propylene glycol, polyethylene glycol, peanut oil and castor oil. The tetracycline is tetracycline per se, chlor-tetracycline, bromtetracycline, oxytetracycline and other antibiotically active tetracyclines having the 4-dimethylamino and 6-hydroxy groups in the tetracycline nucleus. The complex is produced by reacting the tetracycline with 1 to 4, and preferably two, molar equivalents of freshly formed metaphosphoric acid under substantially anhydrous conditions.  It is preferred to add the freshly prepared metaphosphoric acid to a solution of the tetracycline in an anhydrous inert solvent such as methanol, ethanol, dichloroethylene, trichloroethane, dimethylformamide, ethyl acetate dimethylsulphoxide, tetrahydrofurane, acetone or ethylene glycol. The freshly prepared metaphosphoric acid is prepared by treating phosphorous pentoxide with an inert anhydrous liquid such as chloroform and adding an equimolar amount of water calculated to react with P2O5 to yield HPO3.  Preferably a second solvent especially methanol or ethanol is added so that the reactants may be completely dissolved.  The temperature is 0 DEG  to 35 DEG C. and preferably 0 DEG  to 15 DEG C.  The example may be precipitated from solution by the addition of a non-solvent such as isopropanol.  It may be used in pharmaceutical preparations (see Group VI).ALSO:A pharmaceutical composition comprises as an essential ingredient thereof a tetracyclinemetaphosphate complex having a solubility in water in excess of 500 micrograms per mil. water (see Group IV (b)). The tetracycline is tetracycline per se, chlortetracycline, bromtetracycline, oxytetracycline or other antibiotically-active tetracycline having the 4-di-methylamino and 6-hydroxy groups in the tetracycline nucleus.  The complex may be put up in the form of a capsule, tablet, solution, elixir or syrup.  Examples relate to (a) a wool fat and petrolatum base ointment containing tetracycline-metaphosphate complex; (b) capsules containing tetracycline-metaphosphate complex and dibasic calcium phosphate; (c) an elixir containing tetracycline-metaphosphate complex; (d) a veterinary powder containing tetracycline-metaphosphate complex, sugar, citric acid and "Tween 20" (Registered Trade Mark); and (e) a sterile powder for admixture with water containing tetracycline-metaphosphate complex, ascorbic acid, magnesium chloride and procaine hydrochloride.

Title: Triggered ramp voltage generator
IPC: G01R13/32
Filed: 1966-05-03
Abstract: 1,127,804. Semi-conductor pulse and sawtooth circuits. TEKTRONIX Inc. 3 May, 1966 [3 May, 1965], No. 19552/66. Heading H3T. In a circuit for providing control pulses for a ramp voltage generator, an " arming " bistable circuit is first set by a first level of an input signal and enables a second bi-stable circuit to be set by a second level of the input signal. The first and second bi-stable circuits are later held in a reset condition by a pulse from the ramp generator so as to prevent spurious triggering during the flyback. The circuit may be used in a cathode-ray oscilloscope to derive sweep control pulses from the vertical deflection input. As shown in Fig. 3, bi-stable tunnel diodes 40, 50 are normally biased in their low voltage states by the current of transistors 58, 60 (adjustable at 78). Tunnel diode 40 is triggered into its high voltage state by a first level of the vertical deflection signal applied between terminals 72 and 74, thus turning off diode 46 and turning on diode 52, allowing a second level of input signal (adjustable at 70) to trigger tunnel diode 50 into its high voltage state. The resulting pulse is inverted by transistor 79 and fed to a Miller sweep generator (not shown). A reset and hold off pulse 38, initiated by the flyback of the sweep generator, turns on diodes 86, 88, holding the bi-stable tunnel diodes 40, 50 in their reset condition hence preventing further triggering during the flyback. A delay circuit 94, 96 ensures that tunnel diode 40 is reset after tunnel diode 50. Fig. 2 (not shown) relates to the generation of a control pulse 34 by every second cycle of a substantially sinusoidal input signal at 72, 74.

In the electron microscope arrangement of Fig. 1, an image of the diffraction pattern of sample 14, is formed on phospher screens 4 (for a visual display) and 8. T.V. camera 7 is optically coupled to the screen 8 via a window 5 e.g. a single or double fibre optic plate, arrangement or a lens system. Alternatively, the screen 8 is omitted and the T.V. camera target 17, 18 is influenced directly by the electron-flux, window 5 being electron permeable e.g. a channel-multiplier plate. The scanning of the image is preferably in a system of concentric circles, produced by scan generator 43, Fig. 2. The camera 32 output is amplified at 34, integrated at 37 and applied to modulator 40 whose output is pulses of amplitude dependent on the integrator output pulses. Detector 42 is provided to start and stop integration at correct scanning instants, to control the T.V camera electron beam current and to correlate modulator 40 output pulses with particular scans: The circuit output is fed to a computer store. When concentric scans are executed, each integration may be equal to one circular scan, or may take place over e.g. five consecutive circles, or even a portion of a circle. A continuous spiral an elliptical scan or a scan adapted to the shape of the image to be recorded may be used. Scanning frequency and beam current may be variable e.g. a function of radius. When a scanning electron microscope of the transmission or of the reflection type, is used the T.V. camera may be used to act as an annular detector. The recorded information may be compared with information relating to a reference image stored on the computer.

Title: Producing vinyl-substituted pyridines
Inventor: LACEY RICHARD NORMAN
IPC: C07D213/127
Filed: 1958-06-21
Abstract: A vinyl-substituted pyridine is obtained by dehydrogenating an ethyl-substituted pyridine to produce a mixture of the vinyl- and ethylpyridines, distilling the mixture in a column through which is passed, countercurrently to the vapours of the substituted pyridines, an aqueous solution having a pH value less than 5,0, and removing the vinyl-substituted pyridine as distillate.  The ethyl-substituted pyridine may be dehydrogenated to the vinyl-substituted pyridine, for example, by heating it in vapour from in the presence of a dehydrogenation catalyst such as tungstic oxide, vanadium oxide or another oxide of a metal of Group IV to VI of the Periodic Table. The distillation is conveniently carried out at atmospheric pressure but, if desired, higher or lower pressures may be used.  Suitable aqueous solutions are those of phosphoric acid, sodium hydrogen succinate, succinic acid, oxalic acid, formic acid, hydrochloric acid or sulphuric acid.  The unreacted ethyl-substituted pyridine forms an aqueous solution of a salt and is removed from the foot of the column. The separation of the vinyl-substituted pyridine may be improved by introducing a feed of a stronger base than the vinyl-substituted pyridine, e.g. aqueous sodium or potassium hydroxide or ammonia at or below the point at which the mixture of the substituted pyridines is introduced, by a process described and claimed in Specification 852,130.  Examples are given of the separation of 2-methyl-5-vinyl pyridine from a mixture also containing 2-methyl-5-ethyl pyridine.
