Title: Improvements in or relating to lysergic acid derivatives
Filed: 1961-08-29
Abstract: The invention comprises compounds of the formula <FORM:0988366/C2/1> (wherein R1 and R2 are hydrogen atoms or methyl or ethyl groups, R3 is a methyl, ethyl or phenyl group and\sG x y is a <FORM:0988366/C2/2> radical) and their acid-addition salts and their preparation by reaction of the corresponding unsubstituted hydrazides with the appropriate carbonycl ompounds R2.R3.CO and subsequent reduction of the resulting hydrazone. Examples describe the preparation of 9,10-dihydro-D-lysergic acid isopropyl and benzyl hydrazides, D-isolysergic acid benzyl hydrazide and 1-methyl-9,10-dihydro-D-lysergic acid isopropyl hydrazide. A list of salt-forming inorganic and organic acids is also provided. Lysergic acid and 9, 10-dihydrolysergic acid hydrazides substituted at the 1-position by a methyl or ethyl group are prepared by reacting a 1-methyl or ethyl ergol alkaloid (prepared by treating the 1-unsubstituted alkaloid with an alkali metal amide in liquid ammonia and reacting the resulting alkali metal salt with a methyl or ethyl halide) with hydrazine. The lysergic acid derivatives of the invention, at least some of which are stated to have a sedative action and/or to affect the tonus of the blood vessels, may be made up into pharmaceutical compositions with suitable carriers.

Title: Scintillation observer for a specimen subjected to radiation
IPC: G01T1/105
Filed: 1966-12-09
Abstract: Apparatus for readout of a dosimeter glass by detection of the fluorescence of the glass when it is irradiated by ultra-violet light, comprises a unit for holding a glass specimen 15 (for example, as shown in Fig. 1) and a detector unit (for example as shown in Fig. 4) into which the specimen holding unit is inserted to locate the specimen adjacent the detector and an ultra-violet source, for readout. Two embodiments of the invention are described both of which are arranged to operate such that the coupling of the holding unit into the detector unit is by means of bayonettype coupling members-lugs on the inside of the detector unit, coupling with grooves and slots on the holding unit. On insertion, the holding unit is rotated, within the detector unit, through an angle of e.g. 60 . This causes locking of the holding unit within the detector unit backward movement of an internal sliding part of the holding unit and release of the glass specimen at a position adjacent the detector and withdrawal of a shutter which was originally covering the detector field of view. After readout terminates, the holding unit is rotated back again and withdrawn. In the first embodiment (Figs. 1 and 4), the holding unit comprises a cylindrical casing 1 in which can slide a block 10 having a tubular extension forming a chuck-like member made resilient by the presence of slits 14 so that it can hold a specimen 15. Initially on insertion of the holder unit into the detector unit 21, the tubular extension is positioned within a passage 29, with the specimen 15 adjacent the detector window 24, and flush against an opaque seating member 23 next to the recess 22 for the ultra violet source. Also the lugs 33 and spring loaded ball 64 are at the corners of the L-shaped grooves and slots (Figs. 2, 3 not shown) of the holding unit, and the lug 60 is within hole 27. On rotation of the holding unit, the casing of the latter is locked in position, but backward movement of the block 10 occurs, due to the different shaping of the bayonet slots and grooves of casing 1 and block 10. The block carries with it the shutter 25 which originally screened the detector from fluorescent radiation from the specimen. The specimen is released, being prevented from movement by the end of a rod 4 over which the block 10 slides. In the second embodiment (Figs. 5 to 8, not shown) the holding unit includes two channel-shaped members which are pressed together to hold a specimen between them by a sleeve having a conical bore. On insertion and rotation of the holding unit in the detector unit, the sleeve is moved along over the channel members into a position where the members can splay apart and free the specimen. At the same time, a part-tubular shutter, which originally masked the detector, is rotated to clear the field of view of the detector. Other details of coupling members &c. are similar to the first embodiment.

Title: Improvement in or relating to hydraulic drives
IPC: F15B11/05
Filed: 1969-02-25
Abstract: A power circuit 4 is supplied by pumps 1, 2 is parallel the first having a low output and the second a high input. Both pumps are by-passed, 1 by valve 9 responsive to the pressure in the line 6 of the high output pump 2 by valve 10 responsive to the pressure in the line 4. A further overpressure valve 21 may be used to shut down the system by opening the low capacity pumps by-pass (the high capacity pump already being by-passed). Initially both pumps are effective until at pressure P, pump 1 is by-passed. At greater pressure P 2 the high output pump 2 is by-passed, control line 20, and with the fall in pressure in line 6 and consequently line 19 the low output pump becomes effective.
Patent ES-369780-A1 (ES)
Title: Methods of and apparatus for advancing and coiling strand material
IPC: B65H54/82
Filed: 1969-07-12
Abstract: An apparatus for coiling strand material, and of the kind in which the strand 20 is first coiled around a strand-engaging surface 60 such that as each fresh turn is wound onto the surface 60 the lowermost turn on the surface 60 disengages therefrom in coiled form, is characterized in that there is means 68 for applying a force that substantially completely circumscribes said surface to urge the strand material against the surface 60 prior to its becoming disengaged. As shown in the drawing the means 68 is a coiled tension spring. The spring 68 rests on a stationary plate 70 in a housing 72. As the convolutions 62 progress downwardly over the surface 58, the convolutions urge the spring 68 to rotate about its circumferential axis and progress also around the surface 60. This reduces wear on the spring 68. The strand 20 is laid onto the surface 60 by a roller 64 carried by a rotating plate 34 driven by a belt 32. A plurality of rods 76-76 extend downwardly from the drum-type capstan 60 and cooperate with levers 78-78 which swing inwardly into engagement with the rods to form an accumulator system when one of the takeup devices (not shown) is changed. A tapered guide 80 helps to constrain the portions of the wire 20 as they fall to the takeup. The means 68 may be a band of elastomeric material, or a series of contiguous rollers held together resiliently by a spring or rubber band. The strand engaging surface 60 may be stationary or moving.

Title: Electronic supervision circuit for telecommunication systems
IPC: H04Q3/00
Filed: 1970-03-06
Abstract: A circuit for supervising the state of a line circuit uses four transistors with two 1, 5 connected to the "a" ling through choke 11 and two 3, 6 connected to the "b" line through choke 14. A battery is connected to resistor 15 and to Zener diode 20. The output of the two circuits are connected to detector scanner terminals 7, 8 respectively. The transistor 3 is biased to become conductive or non-conductive dependent on the resistance of the subscriber loop. The transistor 1 is connected to conduct and remain conducting whenever the subscriber loop is closed. Thus signals (0, 0) and (1, 1) at terminals 7, 8 represent on hook and off hook conditions respectively. - An additional recall facility is obtained by operating switch 18 which inserts high resistance 18 in the loop thus turning off transistor 3 and provides signals (1, 0) at terminals 7, 8 of detector scanner. Spurious calling conditions caused by earth faults and short circuits are indicated as (0, 1) at terminals 7, 8.

Patent ES-417950-A1 (ES)
Title: Method and apparatus for testing antibiotic susceptibility
IPC: G01N33/483
Filed: 1973-08-17
Abstract: The light scattering of a number of aliquots of a given bacterial/broth suspension, each containing a different antibiotic are rapidly measured and compared with the forward light scattering of a control suspension of the bacteria in the absence of antibiotic. The inhibitory effectiveness of each antibiotic on the growth of the bacteria is then computed from the substantially simultaneous readings and printed out. The bacterial/broth suspension samples are conveniently deposited in a disposable, plastic, transparent, compartmented container or cuvette into which antibiotic discs are introduced into all but one compartment (chamber) from a ganged disc dispenser. After a brief agitated incubation period of about three hours, the covette is inserted in a photometric analyzer which measures the intensity of light scattered at some angle to the incident beam by each sample chamber and compares it with the light scattered at the same angle by the control chamber to which no antibiotic has been added. The relative effectiveness of each antibiotic is computed and recorded to determine which of the antibiotics is most suitable for treating the patient. The partitioned cuvette includes a filling reservoir from which the inoculated broth is introduced as equal volume aliquots into the interconnected lobes of a row of double lobed chambers. Rotation of the partitioned cuvette transfers the equal volumes of broth inoculum from the interconnected lobes to the transparent and separated lobes of the chambers. Then different antibiotic discs are simultaneously dropped within apertured tubes which are located within all chambers except the control chamber. Elution of the antibiotics into the liquid samples begins immediately. The cuvette is then placed in an incubator/shaker for approximately 3 hours at approximately 36 DEG C to promote bacterial growth and antibiotic elution. The light scattering readings are obtained at the end of the agitation/incubation period and the relative antibiotic effectiveness computed in an analyzer into which the cuvette is inserted and indexed past a light source. The light passes through a lens system which directs a beam of light successively through the transparent lobes of the cuvette. The readings are obtained at a predetermined angle of scatter of, for example, 35 DEG . Initial analog signals are converted to binary digits and logarithms to simplify normalization of the antibiotic-mediated inhibition of bacterial growth by the total growth in the control chamber. The normalized growth inhibition values are printed out and rated on a scale of 0 (no inhibition, total resistance) to 100 (complete inhibition, total susceptibility). In addition the total growth, which has occurred in the control chamber during the agitation/incubation period, is printed out as a logarithmic difference (growth index).
