Patent number: 4546615Abstract: Ice lollies are frozen in two-parted moulds which are inserted in rows of freezing pockets in an ice lolly freezing machine. The moulds are thawed loose from the freezing pockets in which freezing has been carried out, are lifted out of the freezing pockets, separated for releasing the frozen ice lollies, assembled and inserted again into a row of freezing pockets. Before the moulds are lifted, a moderate heating of the freezing pockets is carried out sufficient for thawing loose the moulds with respect to the pockets. Then the moulds are lifted and moved to a position outside the area of such freezing pockets of such freezing machine. At the position the moulds are heated for thawing loose the ice lollies. Then the moulds are separated and the ice lollies removed while the moulds are positioned outside the area of the freezing pockets. Now the moulds are moved back to the area of the freezing pockets and are inserted into an empty row of freezing pockets.Type: GrantFiled: December 12, 1983Date of Patent: October 15, 1985Assignee: Brodrene Gram A/SInventor: Klaus Gram

Patent number: 4544059Abstract: A bottle single filer for combining bottles (10) fed in a plurality of rows on an inlet conveyor (11) to a single row on an outlet conveyor (14), has a plurality of oblong separators (38), which are controlled so as to be movable through a closed path in which they extend obliquely across the inlet conveyor in parallel with the transverse rows of bottles on it. At a specific location in this path the individual separator moves down between two bottle rows which it follows until the bottles contact and slide along a barrier (17), which is formed by a transfer section of one side rail and forms a smaller angle with the transport direction than the separators, the bottles being pushed on to the outlet conveyor along said barrier. In connection with the side rails the separators ensure that only one row of bottles at a time can pass, to thereby obviate bridge formation and jamming. This also reduces the risk of bottle collision and thus the noise level.Type: GrantFiled: February 16, 1983Date of Patent: October 1, 1985Assignee: De Forenede Bryggerier A/SInventor: Erik C. Mernoe

Patent number: 4544455Abstract: Salt bridge liquid for use in potentiometric measurement of blood or a blood liquid.The salt bridge liquid contains Na.sup.+ -ions and HCOO.sup.- -ions in substantially equimolar amounts, preferably in a concentration larger than or equal to 1 M, in particular about 4 M.When this salt bridge liquid is used, the potentiometric measurement will give corresponding results when measuring a blood sample and the corresponding plasma sample because the suspension effect which is caused by the erythrocytes and which is seen when using other salt bridge liquids is substantially eliminated. Furthermore, different blood samples with the same ion concentration but with varying erythrocyte content will give corresponding measuring results.Type: GrantFiled: May 17, 1983Date of Patent: October 1, 1985Assignee: Radiometer A/SInventors: Anne R.

Patent number: 4542794Abstract: The alignment of the drill stem and bit of a rock drill rig is corrected when the force of drilling and the feeding power on the drilling machine of the rig has resulted in a change in the direction of the drill stem because of deformation of the articulated and extensible drill boom of the rig and of its pivotally supported drill support on the drill boom. The drill rig is of the type that includes elements for measuring boom lengths and articulation angles, servos for controlling such lengths and angles and a control unit which is connected to the measuring elements and servos for adjusting the drill stem and bit. The various articulation angles which are required to compensate for deformations of the drill boom and drill support are determined as if the drill boom and support were in an unloaded condition, on the basis of measured values of the boom lengths and articulation angles which have been registered in the control unit in an unloaded condition.Type: GrantFiled: April 26, 1982Date of Patent: September 24, 1985Assignee: Ingenior Thor Furuholmen A/SInventor: Hakon E.

Patent number: 4541464Abstract: The filling channel in the top piece of a liquid gas cylinder or a similar container to be filled only to a certain level determined by a float includes a closing valve which in the prescribed filling position of the container is raised from its seat by a pin on a universally journalled pivotal member which by a load is urged toward a given orientation in space. A tilting of the container causes the pivotal member to be rotated, thereby entailing a lateral displacement of the pin away from the closing valve which then occupies its closing position against the seat and prevents further filling until the container reoccupies the prescribed position.When the maximum filling level has been reached, the float causes closing of the same valve, for instance by dominating the load so as to provoke a rotation of the pivotal member.Type: GrantFiled: September 30, 1983Date of Patent: September 17, 1985Assignee: Kosan Teknova A/SInventor: Ole Christiansen

Patent number: 4541149Abstract: A locking device for selectively locking and releasing a rope or a similar elongated, flexible element comprises a channel-shaped frame and a clamping member which is provided with a handle and is mounted swingably within the frame. The clamping member cooperates with a rope abutment surface defined by the bottom wall so as to clamp the rope, when the clamping member is swung in one direction by means of the handle, and so as to release the rope when the clamping member is swung in the opposite direction. In order to render it possible to arrange the handle in a convenient, protected position within the channel-shaped frame in the rope releasing as well as in the rope locking or clamping position of the clamping member, the clamping member and the handle are separate parts, each of which are independently swingable about a common axis, and the clamping member and the handle may be releasably interconnected by means of releasable coupling means, which may comprise a locking pawl.Type: GrantFiled: February 13, 1984Date of Patent: September 17, 1985Assignee: Sophus Berendsen Marine A/SInventor: Jens C.

Patent number: 4540714Abstract: A gas rich in methane is prepared by the methanantion of a synthesis gas containing carbon oxides, hydrogen and optionally other gases in the presence of one or more gaseous sulphur compounds, normally in an amount of at least 10 ppm preferably at least 200 ppm by volume, calculated as H.sub.2 S, with the aid of a catalyst comprising vanadium and/or molybdenum, which during the process is present as one or more sulphides, on a support comprising titanium dioxide.A high activity and a high selectivity for methane are obtained. A further advantage is that, by far, the main constituent of the higher hydrocarbons formed is ethane, which, by conversion into ethylene, is an important raw material in petrochemical synthesis.The selectivity for methane formation may be further improved by promoting the catalyst with compounds, especially sulphides of metals of groups IA, IIA and/or IIIB, particularly cerium.Type: GrantFiled: November 1, 1982Date of Patent: September 10, 1985Assignee: Haldor Torsoe A/SInventors: Karsten Pedersen, Jens R.
