Granted: 2006-01-24
Abstract: A device for holding an objet to a magnetizable surface, comprising a magnetic base including a magnet recessed in a housing and a hook removably connectable to the housing. The magnet has an external face devised to face the magnetizable surface, an internal face opposite the external face and a sidewall. The housing is sized to accommodate the magnet in a loose manner so that an air gap is formed between the housing and the magnet. The housing comprises a side wall that extends beyond the side wall of the magnet such that, in use, an air gap is formed between the magnet and the magnetizable surface. The hook comprises an anchoring section slidably engageable in a hook holder provided on the outer face of the magnetic base and a supporting section adapted to support said object.

Title: Method and device for controlling a hydraulic lift
Inventor: VON HOLZEN RICHARD
IPC: B66B1/24
Filed: 1998-02-04
Granted: 2006-11-14
Abstract: The invention concerns a method and device for controlling a hydraulic lift, wherein a lift car (2) can be moved upwards and downwards in a lift shaft (1). The lift car (2) is connected to a reciprocating piston and is driven by an oil pump (40) which delivers pressurized oil between a tank (41) and a lifting cylinder (3). The oil pump (40) is driven by a motor (39) which is fed by a controllable power-supply part (28). The speed of the lift car (2) is detected by a sensor (13). A control and regulating unit (10) controls and regulates the assemblies influencing the movement of the lift car (2), that is the motor (39) and a valve unit (43). During upwards travel, the speed of the lift car (2) is controlled by regulating the motor (39). According to the invention, during downwards travel, a regulating and controlling effect is exerted on the valve unit (43). At low speeds when the lift car (2) is starting to move or braking, the speed is regulated by actuating the valve unit (43); at faster speeds, such as during upwards travel, the speed is regulated by regulating the motor (39).

The loop members of two adjacent first and second panels overlap each other at a first overlapping point along first edges of the loop members, and at a second overlapping point along second edges of the loop members, with the overlapping loop members defining a hinge portion about which the two loop members of the first and second panels are pivotable. The structure may include a third loop member having one side which is hingedly connected to one side of the first panel. The panels are foldable on top of each other about their respective hinge portions to have the loop members and their associated fabric overlaying each other, and the overlaying loop members are then collapsible to the collapsed positions by twisting and folding to form a plurality of concentric rings and layers of fabric to substantially reduce the size of the structure in the collapsed position.

In one embodiment, the article comprises a flexible sheet material impregnated or coated with two different resins. In an alternative embodiment, the article comprises an extruded sheet material comprising two different extruded materials. One of the resins or extruded materials is soft or resilient compared to the other resin or material. By selectively providing the softer materials at defined regions of the article the hardness of the region can be adjusted. The article may be in the form of an orthopedic casting tape comprising a fabric backing that is longitudinally impregnated or coated with two different curable resins. A harder, first curable resin is used to coat a longitudinally extending center region of the fabric backing; and a softer, second curable resin is used to coat at least one longitudinally extending edge region of the fabric backing. When wrapped around a limb the softer edge regions may be overlapped to form a soft, comfortable edge of the cured cast.

Granted: 2008-07-15
Abstract: The present invention provides a continuous process for making O,O-dimethyl phosphoroamidothioate. In accordance with this process, O,O-dimethyl phosphorochloridothioate is reacted with ammonia and sodium hydroxide; addition of the sodium hydroxide controls the pH of the reaction mixture. The formed reaction mixture contains an aqueous phase and an organic phase. The organic phase of the reaction mixture is separated from the aqueous phase; a second organic phase is solvent extracted from the aqueous phase; and the resultant O,O-dimethyl phosphoroamidothioate is isolated from the combined organic phases via vacuum solvent stripping. In an embodiment of the present invention, the reaction of O,O-dimethyl phosphorochloridothioate with ammonia and sodium hydroxide is carried out in the presence of a solvent.

Abstract: A method of transmitting signalling information in a Public Land Mobile Network (PLMN) between a pair of peer application parts. An adaptation layer is interposed between the TCAP of an SS7 network and a TCP/IP part to allow signalling data to be transmitted to and from an application part via an IP based network. The Adaptation layer provides for translation between global titles or Destination Point Codes (DPCs), used as the basis for addressing in the SS7 network, and IP addresses/port numbers for use in the IP network. The adaptation layer also provides for formatting of messages suitable for processing by the TCP/IP layers, and also for formatting signalling information flowing in the reverse direction.
