Title: A method and an apparatus for identifying foreign bodies in packaged beverages, as well as use of the apparatus.
Inventor: LAURBERG CLAUS KIRKEGAARD
IPC: G01N21/90
Filed: 1997-06-13
Abstract: A method and an apparatus (10; 31) for identification of foreign bodies (4) in packaged beverages, where the package (1; 12; 30) and the beverage are translucent and the foreign bodies (4) have a density greater than that of the beverage. The method is unique in that the package (1; 12; 30) is oriented in a first position in which the foreign bodies (4) are collected on an internal, upwardly directed face (5) in the package (1; 12; 30), and that the package (1; 12; 30) is then turned to at least one subsequent inclined position having an inclination sufficient for the foreign bodies (4) to perform a downward movement along said face (5). During this movement, at least one of the foreign bodies (4) is identified by comparing at least two successive position-determining detections. This provides a method and an apparatus (10; 31) for certain identification of foreign bodies (4) in dark as well as light beverages and in disposable as well as recyclable packages (1; 12; 30).

Abstract: A subsurface signal transmitting apparatus (10) including an insulation coupler (11), a carrier device (12) for mounting the telemetry instrumentation (75), and a by-pass system for avoiding pressure build-up either above or below the apparatus. The insulation coupler (11) includes a housing member (13) having a central opening (16) defined by an interior surface (22) extending in the longitudinal direction and a mandrel member (14) having an exterior surface (32) spaced from the interior surface (22) of the housing member (13) to provide a gap or clearance (33) with an insulating bonding material (29) occupying the clearance. The surfaces are oriented so that when the coupling is in tension at least a portion of the two surfaces experience interacting forces towards each other in the longitudinal direction of the coupling and in event of failure of the bonding material, the mandrel member is unable to withdraw from the housing member. The by-pass system includes a by-pass tube (120) which extends through central openings (3, 61) of the insulation coupler (11) and carrier device (12) and provides for electrically insulating one end of the assembly from the other but allows for pressure equalization via a fluid passage-way (121). The carrier device (12) has a cylindrical body (57) forming external channels (74) for concealing instruments (75) about its circumference.

Title: Fuel supply control system for LPG engine - uses manifold pressures to control flow and evaporation rates through two expansion chambers
IPC: F02M21/02
Filed: 1981-04-11
Abstract: Two expansion regulators ensure that the correct supply of evaporated gas reaches the engine inlet manifold. Gas flows from the tank (7) via an electrically-operated cut-out (8) to the first regulator (1), where the flow and thus the expansion is controlled by a membrane operated valve; the setting of the valve being dependent on the pressure difference between the air inlet and manifold sections of the carburettor (26). The gas flows to the second regulator (14) via a mechanically-operated valve (17) which maintains a constant pressure in the regulator unless the pressure difference in the carburettor is so great that a switch (37) operates causing a solenoid (32,31) to force the valve (17) open.

Patent NL-8602418-A (NL)
IPC: H04N9/88
Filed: 1986-09-25
Abstract: An apparatus for reproducing a pulse-code-modulated signal comprises error-correction means (3) for correcting errors in one or more of the data words forming the pcm signal. When the error-correction means are no longer capable of correcting errors in the pcm signal, they produce error flags on an output (7), which error flags are applied to a control unit (9). From these error flags the control unit (9) derives a control signal which is applied to a muting unit (6) for switching on the muting unit. A method is described by means of which the cont es the control signal from the error flags applied to its input (8). A first auxiliary signal (S1) is generated if (at least) n1 error flags are detected within a first time interval (T1) Subsequently, an i-th auxiliary signal (S i) is generated if (at least) n i error flags are detected within an i-th time interval (T i) which occurs after the instant at which the (i-1)-th auxiliary signal appears. The value of i ranges from 2 to N inclusive. Subsequently, a control-signal generator generates the control signal during a time interval T m which occurs after the instant at which the N-th auxiliary signal is received (Fig.2). A number of examples of the control unit are described.
