The present invention relates to a method and a device for logging non-eruptive production wells. The process is characterised in that the well is activated in order to bring about the production of effluents, on either side of first measuring means (10), and in that the said measuring means (10) are used to treat at least a part of the effluents originating from the upstream side (18) of the...

A simple yet effective method and apparatus control the temperature within a fluidized bed reactor within a desired range (e.g. about 800 DEG -950 DEG C.). Particulate solids in the off-gases from the combustion chamber of the reactor are separated out, and pass through one or more of a plurality of return conduits back to the combustion chamber. The temperature of the returning solids is control...

The adjusting system indicates a target performance value and generates a corresponding performance control pulse. A controller alternately sets an execution period and an execution inhibiting period in accordance with the control pulse. The pulse generator makes a period of a pulse width and a pulse period coincide with the target performance value. A scanning counter is counted up except when...

There are disclosed methods and apparatuses for the assembling of parts using capacitive sensing, both for controlling the closure or "homing" phase of the assembly process and for acquiring one or more of the parts prior to that phase. Assembling of semiconductor parts to essentially two-dimensional and three-dimensional packages, the insertion of a peg in a hole, and an application to tape-autom...

A polyester or copolyester container is made with a heat activated high barrier copolyester label applied to the container sidewall. The process for producing the high barrier container that is a hollow polyester or copolyester body with a barrier label effectively applied to its outer sidewall, includes forming the container by an extrusion blow method, injection blow method, orientation-blow met...

By the combination of two measures, namely the use of slag-wool fibres of an especially small average fibre thickness and the addition of a reviving agent of unusually high viscosity, it becomes possible to needle a slag-wool felt, without the addition of any other fibres, to form a needled felt of high strength and good flexibility. When the needled felt is subsequently made stress-free by heat t...

Process for Coating Glass A process for coating a moving ribbon of hot glass by chemical vapour deposition comprises establishing a first flow of a first reactant gas along the hot glass surface substantially parallel to the direction of movement of the glass, establishing a second flow of a second reactant gas as a turbulent flow at an angle to the glass surface, introducing said second flow into...

An apparatus 1 for depositing onto the surface of a moving ribbon of hot glass 12 a coating formed from the reaction of at least two gaseous reactants. The apparatus includes an open-faced coating chamber 10 in which the gaseous reactants are caused to flow in contact with the glass surface to be coated in a direction substantially parallel to the direction of movement of the glass so as to form t...

A system for providing a progressive-scan video display signal from a received video signal derived from a film having successive image frames by producing odd and even video fields from each film frame, with the video fields being produced at a greater rate than the film frame rate and in a repetitive sequentially varying relationship to the film frames. The system includes one-field delay device...

A system for determining the sequential position of video fields of a received video signal that was derived from a film having successive image frames in accordance with the 3:2 pulldown method, wherein the video fields are produced at a greater rate than the film frame rate and in a predetermined repetitive sequentially varying relationship to the film frames wherein at predetermined positions i...

The cover plate (2) of an earmould (1) of an in-the-ear hearing aid is provided with an aperture (3). A unit (4) can be inserted detachably in this aperture. The unit (4) comprises the amplifier (6), control means (8) and a battery compartment (7), which are all mounted on or are at least partly accommodated in, respectively, a carrier plate (5). The detachable connection between the cover plate (...

The controller is to output results of parallel processing to a controlled system and improve a processing speed. A processing unit comprises a master processing unit (3) and a slave processing unit (4), and an instruction memory (1) and an I/O device (2). The processing units are provided with processors (81,82) connected to the memory (1), operand address memories (61,62) connected to the proce...

A valve comprises a plunger (5) in a coil case (1) and a shaft (12) shifting freely in a body (2). The shaft has two spool valves (4a,4b). An inlet port (13), an exhaust port (3) and an outlet poart (11) are provided in the body, while the spool valves closing and opening the inlet port and the exhaust port. A feedback chamber (9), communicating with the shaft through a feedback channel (8), ha...

A method of culturing cells to form graftable sheets of epidermis and freezing these epidermal sheets for later use in autografts or allografts is disclosed herein.

PURPOSE: To increase capability of both or cleaning and heat transfer by providing a packing element with small flow passages to increase the areas of boundary layers as its shape, thereby increasing the turbulence of the fluid passing these flow passages and increasing the contact surface area. CONSTITUTION: The packing element 17 consists of an inorg. component of a three- dimensional object of ...

A telephone line access control or call-barring unit operates on the monitor-and-clear principle to achieve selective call barring. The unit monitors dialled pulses being sent to an exchange, and recognizes a four-digit security number or authorization code intended to be known only to authorized users for bypassing the call-barring function. It also recognizes one or more two-digit or three-digit...
