Title: Improvements in or relating to the stabilisation of streptomycin solutions
Filed: 1947-05-27
Abstract: Streptomycin is stabilized in solution by the presence of a protective agent in the form of a non-toxic, compatible salt having a mild reducing action and the adjustment of the pH to a predetermined value, the solution so formed being placed in a sealed container and then sterilized by heat, and all operations beginning with the dissolving of the streptomycin and ending with the sealing of the container being performed under an inert atmosphere.  The protective agents are soluble bisulphites, thiosulphates, hypophosphites, formaldehyde sulphoxylates and bitartrates of non-toxic alkaline cations such as the alkali and alkaline earth metals, ammonia, organic amines and heterocyclic groups containing nitrogen of which sodium, potassium, calcium, ethylamine, benzylamine, pyridine and piperidine are specified.  A pH of 3 to 6, preferably 3.68 to 5.5 and for optimum results 4.85, is employed with nitrogen as the preferred inert atmosphere. Examples are given of the stabilization of aqueous solutions of streptomycin sulphate in which (a) sodium metabisulphite and (b) sodium formaldehyde sulphoxylate are the protective agents. Sodium lactate or sodium citrate may also be present.  The Specification as open to inspection under Sect. 91 relates to the stabilization of antibiotics in general.  This subject-matter does not appear in the Specification as accepted.ALSO:Streptomycin is stabilized in solution by the presence of a protective agent in the form of a non-toxic, compatible salt having a mild reducing action, and the adjustment of the pH to a predetermined value, the solution so formed being placed in a sealed container and then sterilized by heat, and all operations beginning with the dissolving of the streptomycin and ending with the sealing of the container being performed under an inert atmosphere.

Title: Combustion unit
IPC: F02K9/95
Filed: 1969-03-19
Abstract: 1,255,694. Igniting propellants. MESSERSCHMITT-BOLKOW-BLOHM G.m.b.H. 19 March, 1969, [21 March, 1968; 30 April, 1968], No. 14453/69. Heading F3A. [Also in Division F1] The invention relates to combustion apparatus in which a solid propellant charge is burned, the charge being of tubular form and being ignited by the gases from a primary charge, the gases flowing along the inner and outer surfaces of the tubular charge towards the combustion chamber outlet, means being provided adjacent the outlet from the internal passage through the charge for throttling the flow of gases so as to increase the flow of gases along the outer surface of the charge so as to produce more uniform ignition along the inner and outer surfaces of the charge. In Fig. 1 a solid propellant charge 2 of tubular form is inserted in combustion chamber 1 which is formed with a combustion gas outlet 12. The charge is held in place by a cover plate 6 which contains a detonator 5, the cover-plate being formed with a flange 10 which is apertured at 10a so as to serve as a screen. A throttle member 7 formed with restricted passages 9 is disposed between the cover plate 6 and the tubular charge 2. A priming charge 4 is located below the tubular charge. An annular space 14 is provided between the outer surface 16 of the charge and the internal wall surface 13 of the combustion chamber. Upon firing of the detonator 5, the gases therefrom fire the priming charge 4, the gases from which pass along the inner surface 15 of the charge, also along the outer surface 16 of the charge, whereby the charge is ignited at both its inner and outer surfaces, the resulting gases passing through the screen 10 to the annular space 11 and thence through outlet 12. The object of the throttle device 7 is to restrict the flow of gases from the priming charge through the internal passage J of the tubular charge and to ensure that a proportion of the gases pass along the outer surface 16 of the tubular charge. The passages 9 of the throttling member may be initially closed by plugs of combustible material enclosed within insulation, the material being ignited by means 19, 20 only when the gas flow through the annular passage 14 attains a predetermined temperature. In Fig. 3 the tubular charge itself is formed with a restricted outlet 21 of star-form 22, while in Fig. 4 (not shown), a restriction member is moulded into the outlet end of the tubular charge. In Fig. 5 (not shown), the outlet end of the tubular charge is initially closed by a thin wall which eventually burns through.

Title: Improvements in or relating to the intermittent or stepwise driving of shafts, wheels and the like
IPC: A47B61/00
Filed: 1926-06-08
Abstract: 253,528. Siemens &. Halske Akt.-Ges. June 9, 1925, [Convention date]. Type-printing telegraphs.-A step-by-step drive is imparted to a shaft, e.g. of a type-printing telegraph receiver, by causing a series of current impulses to energize a magnet which couples the shaft to a continuously-rotating shaft, an arresting device having one member mounted on the driven shaft being moved cut of arresting position solely by the rotation of this shaft. The coupling magnet 17 is energized by the charging or discharging of a condenser 20 upon movement of the tongue 22 of a relay receiving the impulses. The driven type-wheel shaft 1 carries a toothed wheel 8 engaged by a detent roller 9 on a spring- controlled lever 11 which is lifted over one tooth of the wheel 8 by the rotation of the shaft 1 due to each received impulse. In the locking position the lever 11 closes a contact 12 in the circuit of a printing magnet 5. This magnet is slowacting and is therefore not energized until a spacing period occurs following the series of impulses. The paper strip 3 passes between the type-wheel 2 and the printing hammer 4 carried by the armature lever 4<1> of the magnet 5. The paper is fed by wheels 7 one of which carries ratchet mechanism operated by the lever 4<1>.

Title: Logical circuits embodying bistable magnetic storage elements
IPC: H03K19/16
Filed: 1953-05-26
Abstract: 748,558. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 26, 1953 [May 29, 1952], No., 14620/53. Class 40 (4). [Also in Groups XIX and XL (c)] In a logical circuit comprising bi-stable magnetic core storage elements coupled by a transfer circuit to a voltage-responsive device (e.g. a further storage element), the storage elements are each arranged, when changed from an active to an inactive state, to produce in the transfer circuit a voltage pulse, and the transfer circuit includes a rectifier or semi-conductor amplifier, and a source of fixed bias voltage therefor, where by the transfer circuit discriminates against pulses which do not exceed a given threshold value, the magnitude of the pulse in the transfer circuit being determined by the manner in which the elements are interconnected, and by the manner in which they have been activated. In the binary storage apparatus shown in Fig. 1, storage elements 10, 26, each comprising a magnetic core 11 or 29 having a substantially rectangular hysteresis loop are connected by a transfer circuit comprising a germanium diode 22 and bias battery 23. Each element includes three (read-in, read-out and output) windings which may be only single wires passing through a toroidal core. A read-in pulse, representing " 1," applied to winding 16 of element 10 will change the core 11 from a zero-representing to the opposite saturation condition. A subsequent read-out pulse applied to winding 18 will return the core to the zero condition, thus producing in winding 21 a pulse of sufficient amplitude to overcome the battery bias and energize read-in winding 25 of element 26 to change the core 29 to " 1 " condition. This bias will, however, cancel the effect of a smaller output pulse which might be produced by a read-out pulse, when the core 11 is in the zero condition, if the core hysteresis loop is not exactly rectangular; it will also cancel any back transfer pulse produced in winding 25 when a read-out pulse is applied to the element 26. Fig. 5 shows a logical gating circuit according to the invention comprising elements 65, 66, 71, 72. When a read-out pulse is applied simultaneously to all the windings RO an output pulse sufficient to overcome the bias of the battery 75 is produced only if a " 1 " is stored in elements 65 and in 71 or 72 and a " 0 " is stored in inhibiting element 66. A logical " and " circuit also is described (Fig. 4, not shown). In a modification, Fig. 6, a germanium transistor 80 or other semi-conductor amplifier is used in place of a diode in the transfer circuit. When a " 1 " is read out, the pulse from output winding 84 will overcome the bias of 82 and raise the potential of emitter 81 sufficiently to cause conduction between the base electrode 83 and collector 86, the conduction path including the read-in winding 91 and a power supply battery 87. An electron tube also may be used in the transfer circuit.
