Abstract: 1432259 Exercising device H DUNKELGOD 22 June 1973 [1 July 1972 7 Nov 1972] 29918/73 Heading A6M An exercising device consists of two bladders of the same size and shape and made of flexible impermeable sheet material, the interiors of the bladders being connected to one another by connecting means and one of the bladders being provided with an inlet for filling the bladders with a filling medium, the arrangement being such that it is possible to effect a transfer of the filling medium between the two bladders through the connecting means alternately in one direction or the other by subjecting the two bladders to the alternating application and removal of force applied by parts of the human body. The filling medium may be air or water. In a first embodiment (Fig. 1) the two bladders 10, 20 are joined by a tube 30 including a flow restrictor 31 and the bladder 20 is provided with a mouthpiece for inflating the bladders 10, 20. The device may be used to exercise the hands by alternating grasping and kneading motions of the hands. Other examples of use include transmitting alternating forces to the device by means of the feet from a standing position or by means of the palms of the hands from a semi-prone position with the weight of the body supported by the arms. In another example one bladder supports the head and the other bladder supports the buttocks, the head and buttocks being alternately raised. The tube 30 may be removably connected to the bladders 10, 20 so that tubes 30 of different lengths may be used, the length of the tube depending on which parts of the body to be exercised. In a modification (Fig. 2) the device is made from two sheets of material welded together to form the bladders 10a, 20a, and including welds 5a, 5b which define a connecting piece 35 including a connecting opening 30a. In a second embodiment (Fig. 5), particularly suitable for exercising the hands, the bladders 41, 42 are oval in shape and the device is formed by welding together sheets 45 to 48 along their outside edges 49, 50 and at their centres 51 leaving a connecting opening 44. The bladder 42 is also provided with a mouthpiece 43.

Title: Hybrid scanner for objects emitting gamma-rays - determines accurately the point of scintillation independently of the point
IPC: G01T1/164
Filed: 1979-08-13
Abstract: An array of near enough identical crystals of a material which converts gamma-radiation into light, has the crystals near enough in contact with each other, and in contact over the whole length of one side of the crystals, with a collimator. The array is also provided with two photo-multiplier tubes and light mixing prisms to form a device for scanning objects which emit gamma-rays. Each crystal is enclosed except on the surface turned away from the collimator by material which is impermeable to light. On the unscreened side two mirror image optical conductors of transparent material are located. These are sepd. by a narrow gap which coincides near enough with a flat surface of each of them, and their flat base surfaces together with the cross-section of the gap cover at least the whole of the surface turned away from the collimator. The gap in which the material impermeable to light is placed stands vertically on the surface turned away from the collimator. Its plane passes through the centre point of the surface of the row of crystals turned away from the collimator, and also intersects all the crystals of the row. Both photo-multiplier tubes are connected to corresponding surfaces of the optical conductors.
Patent NL-7906721-A (NL)
IPC: B60C11/04
Filed: 1979-09-07
Abstract: A tyre tread comprises an elongate strip having a respective longitudinal groove (2) in each lateral portion of the strip constructed and arranged to partially close when the tread is subjected to tangential forces, e.g. during cornering, stiffening the tread in the contact area to reduce excessive movement of the tread in the contact area whilst maintaining the groove open at the tread surface. Partial closing is achieved by forming the groove as two tracts a first tract, which remains open during cornering, extending from the tread surface and a second tract, which closes during cornering, separated from the first tract by a sudden variation in groove width produced, for example, by a transverse step formed in one of the groove flanks or a protuberance projecting from the base of the groove. <IMAGE>

Patent NL-9200954-A (NL)
Title: Apparatus and method for locating objects in the earth
IPC: G01V3/18
Filed: 1992-05-29
Abstract: Invention for locating objects in the earth, employing a probe which consists of a rod-shaped element having a thickness of 20-24 mm and a measuring unit detachably linked to said element. The measuring unit is formed by a housing which all but smoothly adjoins the rod-shaped element and contains measuring instruments for detecting objects. To make it easier to push the probe into the earth, the free end of the housing is provided with a strengthened conical point which can be freely rotatably mounted in the housing. In another embodiment, the probe can be accommodated in a hollow drilling member and be guided so as to axially displaceable therein. The invention also comprises a method for using this device if a water-impermeable layer is present in the earth. This method is distinguished by the drilling member being screwed into the earth to just above the water- impermeable layer (water seal layer), the probe being pushed downwards through this layer as far as the harder subsoil and then being moved back up again to carry out the measurement, the drilling member being screwed out of the earth and the drilling hole being filled with suitable material. Preferably, the drilling member while being screwed out of the earth is held back somewhat, so that the vertical upward velocity of the drilling member is smaller than the product of the rotational speed and the pitch of the drilling member.

Patent PT-73873-A (PT)
Title: Process for the purification of waste water and/or waste water sludge
IPC: C02F3/28
Filed: 1981-10-23
Abstract: A purification process for waste water and/or waste water sludge, comprising a methane fermentation and subsequent oxidation of the reduced compounds present in the effluent of the methane fermentation by means of aeration, whereby the sulphide from the effluent of the methane fermentation is used as electron donor by the denitrification and whereby the residual reduced compounds from the liquid effluent from the methane fermentation not until the subsequent next step are oxidized by aeration. 
<??>In this way the suiphldes, produced by the methane fermentation, are used in appropriate way and simultaneously converted in non troublesome or innocent sulphate. 
<??>In the liquid effluent, remaining after denitrification, the ammonia, which was occurring in the effluent is still present; this ammonia is subsequently oxidized into nitrate at the aeration, whereby the sulphide cannot interfere with, as this sulphide was converted in sulphate with the denitrification. As no sulphide is more present, the aeration is demanding less air and aeration may moreover be more simple. 
<??>The hydrogen suiphide from the gas formed by the methane fermentation also may be used for this purpose, giving in this way the greatest utility of the products formed with the methane fermentation, while the gas is purified in a simple way.
