Abstract: The present invention discloses a by-pass valve (18) for use in well testing. It is desirable to test a petroleum formation under both static and flowing conditions. This has usually been effected utilising complicated and relatively expensive apparatus and procedures. 
<??>The present invention provides for the use of a simple by-pass valve (18) which can be retrievably located in well tubing by simple wire-line techniques. The valve (18) of the present invention has a body (23,24) having a seat (26) therein, a valve member (27) being cooperable with said seat (26). A first spring (29) urges the valve member (27) towards one of open and closed positions and a plunger (31) is connected to the valve member (27) to move with the valve member (27) between the open and closed positions. The connection between the plunger (31) and the valve member (27) provides for movement of the plunger (31) relative to the valve member (27) after the valve member (27) reaches the other of said open and closed positions. A second spring (38) opposes relative movement between the plunger (31) and the valve member (27) and pulling means (43) are arranged to releasably latch onto the plunger (31), latch release means (36) being arranged to release the pulling means (43) from said plunger (31) upon movement of the plunger (31) a selected distance towards said other position after the valve member (27) has moved to said other position. Thus the present invention basically provides a well testing system and method in which a by-pass valve (18) is positioned in the tubing (14) and a probe (19) run on a line from the surface opens and closes the valve (18) with vertical movement of the probe (19). The probe (19) when located in the valve (18) is exposed to formation fluids and may transmit back to the surface, or may record information about the formation. The probe (19) may also collect a sample of fluid to return to the surface with the probe.

Abstract: A thin electron accumulation layer is generated along a heterojunction between two different semiconductor layers (21,22) each of which has a different electron affinity from the other. This electron accumulation suffers a less ionized-impurity scattering, because its thickness does not exceed the spread of an electron wave. A channel constituted by this electron accumulation enjoys an excellent magnitude of electron mobility particularly at cryogenic temperature. A layer configuration fabricated with two different semiconductors (21, 22) having different electron affinity from, and similar crystal lattice coefficient with, each other and interleaving a single heterojunction therein is effective to improve the electron mobility. Such a layer configuration can be employed for production of an active semiconductor device with high electron mobility, resulting in a high switching speed. Such semi- conductor devices, including an FET, CCD et al, exhibit an excellent transfer conductance Gm, and may be constructed in a number of ways.

Abstract: A cutting or shaping mechanism is described in which the cutting or pressing force is applied to a moving blade or shaping assembly (20, 83,102,203) over a limited part of the length of that assembly, including where the assembly is in engagement with the work. The application of the cutting or pressing force is moved progressively along the assembly to cause the assembly to roll on the work and progressively cut or apply pressure to the work. The invention is particularly applicable to a rolling cut shear having a single moving blade assembly (20) or a pair of oppositely curved moving blade assemblies (97, 102).

Abstract: The invention is concerned with starting of electrical machines from a sound emitting device and is particularly concerned with safety circuits for the start of a coal getting machine on the sounding of a klaxon giving warning to mine workers underground that the machine is to be started and hence to keep clear. The signal from the klaxon is detected as to certain predetermined parameters including amplitude, frequency and the rate at which the klaxon is being operated since it would normally be controlled by a water driven pump. The signal is then fed to a discriminator circuit which then determines that these parameters are correct. Two such circuits are provided in parallel with each other and a signal to enable the machine to be started is only provided at an output terminal when the correct signal is found and detected by both circuits simultaneously.

Abstract: The manufacture of non-returnable packages for e.g. milk is frequently carried out by the conversion of web-shaped, laminated packing material to a tube, filling of the tube with milk and sealing and forming to filled packing containers of the desired, e.g. parallelepipedic, shape. During the forming, which is done by means of external forming devices, the contents are made use of as a holder-up for the forming devices pressed-on from the outside, so that the desired shape can be achieved without creasing or other deformations. 
     The abovementioned forming principle works less well if the packing containers are not to be completely filled but have a certain air space, so-called head-space. The proportioning of the contents also becomes uncertain and the desired accuracy of volume cannot always be achieved. These difficulties are overcome if the contents are mixed prior to filling with gas, preferably sterile air, in appropriate proportions, so that the contents obtain a foam-like character, using a gas volume which is in a suitable proportion to the air space of the finished packing container. The invention relates to a method as well as to a manner of proportioning the contents in the manufacture of packing containers.

Abstract: A composite thickening agent comprising two or more thickening agents of different sensitivity to ions and a component which is ionizable in water, indicated here as "ionic component". The thickening agent components are selected and proportioned so that each one, being sensitive to a different degree of ionic concentration, has a different thickening action in the presence of different levels of dilution. In practice the less sensitive ones work at greater ionic concentration, the more sensitive ones at higher levels of dilution (lower ionic concentration). In this way the composite thickening agent allows the viscosity of an ionic solution or suspension to be kept relatively constant during the entire process of dilution.
