Filed: 1959-01-01
Abstract: Vinyl pyrazoles of general formula <FORM:0887365/IV (a)/1> in which R1 is an alkyl group and R2 is an alkyl or an aryl group may be used for the preparation of polymers and copolymers.  The vinyl pyrazoles may be polymerized in the molten state, in solution in water or an inert organic liquid or in suspension in water.  The polymerization is preferably carried out at a temperature up to 100 DEG C. in the presence of one or more free radical catalyst or by irradiation in the absence of a catalyst. Copolymers may be prepared by copolymerizing at least one of the vinyl pyrazoles with at least one compound containing at least one ethylenic linkage, e.g. acrylonitrile, dinonyl maleate, ethyl acrylate and vinyl acetate.ALSO:The invention comprises vinylpyrazoles of general formula <FORM:0887365/IV (b)/1> in which R1 is an alkyl group and R2 is an alkyl or an aryl group.  They are prepared by reacting the corresponding 3,5-disubstituted pyrazole with acetylene at 10-30 atmospheres and 130 DEG C.-230 DEG C. in the presence of a vinylation catalyst. Preferably, the reaction is carried out with the pyrazole in suspension or solution in an inert liquid, e.g. xylene, toluene, kerosene or chlorobenzene.  Preferred catalysts are the cadmium salts of weak acids but zinc salts of weak acids or the potassium and sodium derivatives of the substituted pyrazole may also be used.  If desired, a polymerisation inhibitor, e.g. hydroquinone, catechol or phenyl-b -naphthylamine, may be present.  The new vinylpyrazoles may be used for preparing polymers and copolymers.

Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, direct anti-tumor proliferating, anti-inflammatory and anti-collagenolytic activities have been obtained by an improved process. The process comprises the steps of obtaining a homogenate of cartilage in an aqueous solution, this homogenate being centrifuged and further fractionated to obtain a total extract having molecules of a molecular weight comprised between 0 to 500 KDa. The composition of the liquid extract has then been investigated by different ways. Further fractionation of this extract led to the preliminary characterization of some of its active components. Due to the multiplicity of biological activities of the total liquid extract, it can be used for treating numerous diseases or conditions such as those having components selected from the group consisting of tumor proliferation, angiogenesis, inflammation and collagenolysis. This extract has no offensive effect on normal body functions. Therefore, this shark cartilage extract has a very promising therapeutic value. The process for the obtention of cartilage extracts is simple and efficient. The unexpectedly valuable products obtained by this process are therefore an indication of a new and non-obvious process.

Patent JP-S60144703-A (JP)
Title: Variable focal length lens
Inventor: BABA TAKESHI
IPC: G02B3/14
Filed: 1984-01-05
Abstract: PURPOSE:To increase the variable amt. of refracting power and to enable easy removal of the adverse influence by the intricate deformation of a refracting face by deforming a transparent elastic material formed preliminarily and internally with a nonuniform refractive index distribution. CONSTITUTION:The inside diameter of a cylindrical piezoelectric element 2 enclosing the circumference of an elastic material 1 can be changed by impressing a voltage thereto. For example, when the inside diameter decreases, the surface 6 of the material 1 existing at the open end of the cylindrical piezoelectric element increases further the convexity and if the refractive index distribution formed preliminarily in the material 1 is assumed to have a positive refracting powder, the positive refracting power increases further and the refracting power changes largely as a whole. The elastic material having so-called high elasticity is desirable; for example, silicone rubber and ethylene propylene rubber are most preferable in terms of transparency. Such high-elasticity rubber has a Poisson's ratio of as high as 0.45-0.49 and has a small volume change. The refractive index at each point in the elastic material is therefore virtually the same before and after the deformation and the refractive index is determined only by the movement owing to the deformation at each point.

Title: Earthquake-predicting apparatus
Inventor: HONDA SHIROU
IPC: G01V1/00
Filed: 1981-01-01
Abstract: PURPOSE:To make it possible to predict an earthquake by a method wherein a box-shaped container with narrow lower and wide upper parts is placed on the ground to fill its inside with soil and to measure the fluctuation of voltage of the upper portion of the container. CONSTITUTION:A box-shaped soil container 4, of which the lower portion is made cylindrical 3 and the upper porition is enclosed with a bottom plate 4 having a wide area and a horizontal frame 15, is placed on the ground 6 to contain soil 5 and soil 5'. When an earthquake is about to occur, the voltage of a ground current changes, whereas electrons are transmitted one after another  up to the soil 5' in the box shape through the rod-shaped soil 5. These electrons collide with an electron blocking board 19, which reflects them and allows them to collide with one another in the soil 5' while amplifying the electron changing ratio, the electrons being made to flow back to the ground 6 through a rod 9 buried in the soil 5', a conductive wire 8 and a rod 11 buried in the ground. Thus the occurrence of an earthquake can be predicted by measuring the current by an instrument 7 for measuring the change of ground current.

IPC: H01F7/08
Filed: 1965-01-01
Abstract: 1,089,571. Electromagnetic devices. ETABLISSEMENTS BRESSON-FAILLE-MARCH- AND. Jan. 1, 1965 [Jan. 2, 1964], No. 109/65. Heading HIP. [Also in Division F2] An electromagnetic resettable release device comprises a magnetic circuit (Fig. 1) wherein a flat bar 1 wound with a trip coil 2 is assembled in a magnetic circuit with L-shaped polepieces 3, 4 defining a gap co-operating with a flat overlying rectangular armature 5 movable perpendicularly to the plane of the Figure and spring biased towards an operated position in which to close the gap. A cylindrical permanent magnet 6 extends between L-shaped members 7, 8 overlying members 1 and 4, and a hollow cylindrical ferromagnetic screw 20 engaging a threaded bore of support 7 is rotatably adjustable to enclose more or less of the magnet to vary the flux threading the magnetic circuit 1, 3, 4. The flux due to the permanent magnet divides into components traversing member 4 and the airgaps 12, 15, 16 and traversing members 1, 3, 4 and airgaps 12, 11, 13, 14, 16. The release flux due to coil 2 divides into a component traversing airgaps 15, 16 and member 4 and a component traversing airgaps 15, 11, 13, 14, 13. The release flux due to coil 2 traversing armature 5 and airgaps 13, 14 opposes that traversing the same path due to permanent magnet 6, and the armature is spring- biased towards its released position so that on energization of the coil 2 by direct current in the appropriate sense the armature is released. Energization may be by alternating current when release will be effected by the appropriate. current half-cycle. A shaft 23 to which the armature 5 is flexibly attached serves to restore it to engagement against a U-shaped leaf-spring 50 adjustable by screw 55 and nut 56 (Fig. 15) while armature movement is guided by a spring blade 26 parallel to its direction of motion. A non-magnetic plate 40 (Fig. 10, not shown) serves as a support for the components of the device, to which members 3, 4, 7 and 8 are affixed, and into which studs 35, 36, 37, 38 may be driven (Fig. 8, not shown) to space the armature 5 from members 3, 4 in the operated position. The complete device may be enclosed in a two-part casing 70, 71 (Fig. 18) orificed at 73, 74 to permit adjustment of magnet screw 20 and spring 50.

Title: Controlled Semiconductor Switch.
IPC: H01L29/08
Filed: 1968-01-02
Abstract: 1,182,852. Semi-conductor devices. GENERAL ELECTRIC CO. 2 Jan., 1968 [2 Feb., 1967], No. 269/68. Heading H1K. A four-layer controlled semi-conductor device comprises at least two auxiliary regions on an end layer in addition to the main electrode thereon, these regions being overlaid by conducting material and connected together, one region being much closer to the gate electrode than the other and this one region being spaced further from the main electrode than the other. This construction allows more rapid switching on than was permitted in previous constructions, the initial discharge being transferred from the region near the gate where a comparatively high resistance exists between the auxiliary region and the main electrode to a path adjacent the region further from the gate where the corresponding resistance is lower and which on account of its distance from the gate has undergone no heating in the initial triggering discharge. In Fig. 1, the main electrode 17 of a silicon four-layer device is surrounded by an annular gold ring 20, 21, the portion 20 constituting the conducting material overlying the auxiliary region nearer the gate electrode 19 and the portion 21 constituting that overlying the other auxiliary region, the two portions being connected together by the remainder of the annulus. The thickness of the end layer 15 is reduced between the main electrode and the annulus to increase its effective resistance over this region. In Fig. 1, the annulus is eccentric with respect to the electrode 17 so that the distance D exceeds the distance d; in a modification, Fig. 3 (not shown), the annular ring itself is of varying thickness in a radial direction. In other modifications entirely separate first and second auxiliary regions are provided, these regions being interconnected by wire conductors. The semi-conductor device may be enclosed in a hermetically-sealed insulating housing.
