Title: A new antibiotic ristocetin b
Filed: 1957-11-20
Abstract: <PICT:0843560/IV(b)/1> <PICT:0843560/IV(b)/2> Ristocetin B is produced by growing a ristocetin B-producing strain of Nocardia lurida in an aqueous nutrient containing medium, treating with an adsorptive material to adsorb thereon the ristocetin activity present in the broth, eluting with an acidified aqueous polar solvent, removing the organic solvent, adjusting the resulting aqueous solution to pH 4 to 5, passing the solution through a carbon chromatographic column to adsorb the ristocetin washing out water solubles and eluting with an acidified, aqueous, polar organic solvent, collecting fractions having an Rf value of 0,1 to 0,20 (system consisting of 80 parts of methanol, 20 parts diionized water 1,5% NaCl) concentrating and lyophilizing.  The adsorbents are activated carbon, ion exchange resins and cellulose.  The eluate may be aqueous acetone, methanol, ethanol, isopropanol and tertiary butanol acidified to pH 2,0 by means of an acid such as sulphuric or acetic.  In the chromatography step, the carbon may be mixed with an equal amount of diatomaceous earth.  Further purification is obtained by passing an aqueous solution through an acid washed alumina column, washing with a substantially water free polar solvent e.g. methanol, eluting with an aqueous polar solvent, concentrating and pyophilising.  Ristocetin B is active against many micro-organisms including pneumococcic, streptococci and staphylococci; the sulphate contains 52,9 to 53,5%C, 5,5 to 5,9% hydrogen, 5,6 to 6,6% nitrogen and 1,3 to 1,5% sulphuric; the sulphate shows absorption in the infra red at 3,0, 3,42, 6,06, 6,28, 6,64, 6,84, 7,28, 7,6, 7,8, 8,25, 9,4, 12,0-12,6 and 13,9 microns (Fig. 3); it is stable at neutral and acid pH and is soluble in water, dilute acids and alkalis insoluble in most organic solvents. Ristocetin B sulphate is converted to the chloride by passing a solution over an anion exchange resin e.g. "Amberlite IR-4B" (Registered Trade Mark) in the chloride form. Ristocetin B phosphate and picrate are prepared by precipitation from an aqueous solution of ristocetin B by addition of the corresponding acid.  Ristocetin B may be used medicinally (see Group VI). Specification 765,886 is referred to.ALSO:An intravenous injection comprises an isotonic sodium chloride solution of vistocetin B (see Group IV(b)), an antibiotic effective against pneumococci, streptococci, staphylococci, mycobacteria and others.  Specification 765,886 is referred to.
Patent GB-1558884-A (GB)
Title: Electronic heat quantity meter
IPC: G01K17/18
Filed: 1976-09-01
Abstract: A pressure probe (2) is used to measure the ram pressure prevailing in a flow, which is proportional, via a square-root extractor element, to the flow velocity, which is proportional, in turn, to the rate of flow. Two temperature sensors in the feed and return of a heating system measure the cooling of the medium. If the rate of flow is multiplied by the temperature difference, a value is yielded which is proportional to the quantity of heat. The ram pressure is converted into an electrical signal in a pressure transducer (4). This transducer (4) is, for example, unstable with respect to temperature changes or changes in the static pressure, i.e. in the cases mentioned measurement errors arise. In order to exclude these, the transducer (4) is regularly restabilised by means of the so-called zero adjustment, in which a new zero point is established. In order to carry out the zero adjustment, the solenoid valve (5) is used to produce equality of pressure at the diaphragm of the pressure transducer (4). In this heat flow meter, the influence of temperature, fluctuations in the static pressure and ageing at the pressure transducer are excluded, and the endurance properties of the measuring system are thereby improved. <IMAGE>

Title: Process for the preparation of a petroleum distillate with an improved smoke point
IPC: C10G65/08
Filed: 1964-09-07
Abstract: Petroleum distillate with an improved smoke point is prepared by partly desulphurizing the feed with hydrogen in the presence of a catalyst, splitting the product of this step into at least two streams, for example by distillation, reducing the aromatics content of at least one (but not all) of the streams, and blending the product resulting from such stream or streams with the other stream or with at least one of the other streams.  The stream (or streams) which is to be subjected to dearomatization may previously be subjected to an extensive desulphurization. The dearomatization may be effected by hydrogenation, preferably in the presence of a compound of nickel on kieselguhr or platinum or rhodium on alumina, which latter may also include halogen. Preferred desulphurization conditions are:-  H2 partial pressure, 20-80 kg./cm.2 abs. Temperature, 275-360 DEG  C. Space velocity, 0.5-12 tons oil/m3 catalyst/hour. Hydrogen rate, 10-250 Nm3 H2/ton oil.  Hydrogenative dearomatization may be carried out at:-  Total pressure, 20-90 kg./cm2. abs. H2 partial pressure, 5-50 kg./cm.2 abs. Temperature, 100-350 DEG  C. Space velocity, 0.5-10 tons oil/m2 catalyst/hour Hydrogen rate, 25-300 Nm2 H2/ton oil.  The extensive desulphurization may be effected with the same catalyst as employed for the partial desulphurization, employing the same conditions except that the temperature is 350-400 DEG  C. Suitable catalysts comprise metals of the VIth and VIIIth Groups of the Periodic System, and their oxides or sulphides, supported on a conventional carrier, preferably alumina.  They are desirably insensitive to hydrogen sulphide, for example cobalt-molybdenum-alumina and tungsten sulphide-nickel sulphide-alumina.  Specification 794,809 is referred to.

Title: Improvements relating to apparatus for marking laundry
IPC: B65C5/06
Filed: 1928-12-15
Abstract: 312,037. American Laundry Machinery Co., (Assignees of Garvey, J. M.). May 18, 1928, [Convention date]. Machine details.-A stapling machine is modified for use in attaching identifying tags to laundry in that system of marking laundry in which each article of a particular lot is marked with a characteristic tag, such tags being stacked in different holders, such as are described in Specifications 285,333 and 298,268, [both in Class 73, Labels &c.], so designed as only to receive the appropriate tags. Each holder comprises an elongated casing 1, Figs. 5 and 6. This includes end walls 5, 6 and bottom, upwardly inclined, flanges 3 which engage slots 11 in the tags, Fig. 9. Below the top wall of each casing is a spline 8 shaped to fit a recess 10 in the tag, each group of tags having a particularly shaped recess. The flanges 3 are discontinued adjacent the front wall 5 to leave a slot through which the tags can be inserted into the holder, and a slot 26 is also formed in the top wall of the holder. The co-operating spline 8 and recess 10 ensure that only a correct tag can be inserted in a particular holder. Each holder is carried, for example on a wall, by a plate 16 having a boss 17 to fit into the rear end of the holder and a spring latch 21 to engage a slot 19 in the holder. Each holder may have a graduated slot 24 to indicate the number of tags it contains. Each tag is formed with a pair of holes 12. For marking a lot of laundry, the appropriate holder 1 loaded with tags is mounted on a stapling machine 27 of any preferred form. The holder is held in a vertical position on the machine, its front plate 5 engaging a recess in the work-table 38 and its rear end being clamped by a spring plug 57. The tags, which fall by gravity to the lower end of the holder into line with the slot 26, are fed singly to a point 37 where their holes 12 are in line with the stapling mechanism. As each tag comes into position, an article of laundry is placed over it and a staple is inserted and its legs 13<1> clinched. The tags are fed forward between guides 44 by a pusher 42 operated by a togglelinkage 45, 47, rod 51, and treadle 35. The latter is arranged to operate first the pusher and then a clutch rod 31 whereby a motor 28 is caused to operate the stapling mechanism. When a batch of articles has been laundered, the articles are sorted into lots by means of the identifying tags, and the. latter are then removed.

Title: Improvements in or relating to an arrangement for converting a control potential into pulse-width-modulated rectangular impulses
IPC: B65D41/12
Filed: 1960-10-28
Abstract: 907,743. Converting. INVENTIO A.G. Oct. 28, 1960 [Nov. 5, 1959], No. 37114/60. Class 38 (2). [Also in Group XL (c)] In a pulse width modulator for controlling semiconductor switching amplifiers, the control potential is converted into pulses of corresponding amplitude which are amplified without transfer of D.C. component and used to charge a capacitor which is discharged to a fixed potential during the intervals between pulses. A further stage is provided to convert the sawtooth waveform thus formed into pulses of corresponding duration. The control potential shown at a in Fig. 2 is fed to terminals 11, 12 of Fig. 1. The normally conductive transistor 2 is cut off by pulses b so that pulses c, provided at the collector, may be amplified by an A.C. coupled-amplifier 4 giving waveform d. Capacitor 5 is charged from waveform d via the base emitter circuit of transistor 7. At the end of each pulse d transistor 7 is cut off until capacitor 5, discharging with constant current via resistor 9, again renders transistor 7 conductive, giving waveforms e at the base and f at the collector. Waveform f is squared by an overdriven amplifier or a Schmitt trigger 10 giving waveform g which is used to control semiconductor switching amplifiers the outputs of which control semiconductor or gaseous rectifiers or the control winding of a D.C. machine or magnetic amplifier. The system may be used with an A.C. or A.C. + D.C. control voltage applied to terminals 11, 12 if pulses b are synchronized with the A.C. input.

Title: System for converting analogue signals to multiplexed digital data
IPC: G06F3/05
Filed: 1977-09-06
Abstract: A programmable control device (A) supplies digital data depending on analog signals via data lines (D0 - D7). The control device includes a central processing unit (10) in the form of a microprocessor, having address lines (A0 - A15), the data lines, and control lines for outputing a write signal. When the write signal is received, the digital data which is present on the data lines is passed to data recording devices. The central processing unit is connected to an analog-digital conversion module (100). When it receives a conversion signal (ADC), this module converts an analog signal which is fed to it into a digital signal for the data lines. Said module is connected to a number of analog signal input modules (120, 122, 124), to which addresses are output by the central processing unit (10), so that the analog signals to be converted to digital data are passed to the conversion module (100). Analog signals can be particularly simply and reliably converted into digital data using the device described above. <IMAGE>

Abstract: 1,222,496. Wells &c. BAKER OIL TOOLS Inc. 24 July, 1969 [13 Aug., 1968], No 37221 / 69. Heading E1F. A well has a production pipe C. and a packer P and a valve V are set in the pipe, the valve being connected to a control tube T and the pipe C being connected to a flow line F. A control apparatus D is connected to the flow line, the control tube and a source of control pressure 15, the apparatus acting so that the control pressure is vented through a pipe 17 to reduce pressure on kerosine in the control tube and close the valve when the pressure in the flow line falls below a predetermined value. In the control apparatus a piston 86 is subjected to the flow line pressure and connected piston 87 is subjected to the control pressure the pistons moving to the left to open the pipe 17 to vent the control pressure when the flow line pressure falls below the predetermined pressure and the pistons moving rapidly after their initial movement since the pressure on either side of piston 86 is then balanced. Means 105 permit resetting of the control apparatus. The valve C comprises a body 20 housing a reciprocable sleeve 31 having its bore closed by a plug 50 which is removable to permit operations on the well bore below the valve. When the flowline pressure is above the predetermined pressure, the control pressure acts on the kerosine to hold the valve in its lower position so that well fluid flows through the packer, the aligned ports 2, 39, and the annulus A to the flowline. Reduction of the flowline pressure below the predetermined pressure vents the control pressure to reduce the pressure on the kerosine to permit the sleeve to rise under the pressure of the well fluids and stop production of well fluid.
