Title: Oil recovery apparatus
Inventor: CARTER STEPHEN JOHN
IPC: E02B15/04
Filed: 1982-05-04
Abstract: Apparatus for the removal and recovery of oil from the surface of a body of water comprises: a marine vessel having a 'false' or extended bow section in which is mounted an endless mesh belt elevating conveyor 3 which entraps oil and carries it clear of the water: a de-oiling zone through which the belt passes and in which the belt is cleared of oil by jets 7 of compressed air or inert gas and means for collecting the oil cleared from the belt and storing it. The belt extends over approximately 75% of the width of the vessel and is made up of numerous sections of plastics-coated expanded metal mesh fixed to high tensile rods which extend the whole width of the belt, providing an arrangement which is both strong and flexible. This arrangement also greatly reduces the possibility of belt failure due to metal fatigue induced by cyclic loading since the belt sections do not have to bend around the drive and guide rollers. <IMAGE>

Title: Calliper gauge
Inventor: WERCKMEISTER CLAUS
IPC: G01B3/46
Filed: 1982-08-25
Abstract: A calliper gauge for internal and external measurements has two relatively movable arms 2,3 which are brought into contact with the object to be measured. The movable arms actuate a measuring mechanism with a shaft of which a rotation proportional to the movement of the arm 3 is transmitted to a display system 13, 14, 18. To make possible a reliable evaluation of the measurement and a high degree of accuracy, and to facilitate the so-called two point measurement, according to the invention the shaft carries an incremental encoder. This produces signals representing in number the shaft rotation. With the encoder is at least one sensor suitable to receive the signals, and the output of the sensor is connected to a signal processing arrangement in which the train of signals is converted into digital signals for a digital display system 31. <IMAGE>

Title: Method of control of NC machine tools
Inventor: MORITA EIICHI
IPC: G05B19/4093
Filed: 1982-11-09
Abstract: In an NC machine tool, all control data necessary for preparing machining data is inputted into a control device by key switches provided on an operating board. The data necessary for machining a workpiece stored in a microcomputer contained in the NC machine is reduced to the lowest minimum, while various data, such as the paths of movement of tools during rough machining, rough finish machining and finish machining, actually needed for machining the workpiece are successively computed on the basis of the data stored in said microcomputer in advance. Thus, data associated with a variety of workpieces can be processed with a minimum of memory capacity, and complicated shapes having concaves and convexes can accurately be machined in a simple operation. When it is desired to machine a workpiece by two tools with different nose radii in two machining steps the path of movement of an imaginary cutting edge is calculated to avoid over or under cutting. <IMAGE>

Title: Improvements in or relating to a roof structure ventilation during a fire
Inventor: LAGERBLAD AKE ERIK
IPC: E04D11/02
Filed: 1984-03-01
Abstract: A roof structure is designed so that in the event of a fire arising an opening will be created in the roof to ventilate the space containing the fire. The roof consists of a supporting sublayer of aluminium panels 11, carrying a heat insulating layer constituted by small elements 14 of incombustible material such as mineral wool. This is superposed by a layer of blocks of closed cell plastic material and a top layer of gravel 17. In the event of a fire arising a region of the aluminium panels above the fire will melt, permitting the small elements of mineral wool to fall downwardly. The exposed plastics material will melt, but the upper surface of the plastics material layer will still be covered by the gravel. An opening will thus be formed in the roof, permitting ventilation of the fire, but with a minimum risk of the fire spreading laterally through the roof structure. <IMAGE>

Title: Oscillating device for determining and/or monitoring a predetermined filling level in a container
Inventor: PFEIFFER HELMUT
IPC: G01F23/296
Filed: 1987-01-22
Abstract: A device for determining and/or monitoring a predetermined filling level in a container (12) comprises a membrane (13) clamped at the edge and two oscillating rods (14,15) each rigidly connected to the membrane (13). On the side of the membrane (13) facing the filling material a detector rod (16) is also rigidly connected to the membrane (13). The natural resonance frequency of the oscillating system formed by the detector rod (16) and the membrane (13) is greater than the natural resonance frequency of the oscillating system formed by the rods (14,15) and the membrane (13). An excitation means sets the rods (14,15) in natural resonance in oppositely directed transverse oscillations. As a result a forced oscillation outside the natural resonance frequency thereof is imparted to the detector rod (16). When the motion of the detector rod (16) is retarded by immersion into a filling material energy is withdrawn from the oscillating system. An evaluating circuit generates a signal which is dependent on the oscillation amplitude of the rods (14,15) and which can be used to display the filling level and/or initiate switching operations. <IMAGE>
