Patent CA-2461101-A1 (CA)
Title: Vibratory transducer
Inventor: WENGER ALFRED
IPC: G01F1/00
Filed: 2002-09-17
Abstract: The invention relates to a measuring sensor (1) that comprises at least one at least temporarily vibrating measuring tube (101) with a defined lumen of the measuring tube for carrying a fluid. The measuring tube (101) communicates with a connected pipeline via an inlet pipe (103) leading to an inlet end an d via an outlet pipe (104) leading to an outlet end, and performs, when operating, flexural vibrations about a vibration axis that imaginarily links the inlet and the outlet end. The measuring tube (101) has at least one arcuate tube segment (101c) with a defined dimensional shape that is contiguous on the inlet end and on the outlet end to a straight tube segment (101a, 101b). Directly on the arcuate tube segment (101c) or in the immediat e vicinity thereof at least one reinforcing element (111) serving to stabilize the dimensional shape and optionally an additional reinforcing element (112) are fixated. Those reinforcement elements (111, 112) substantially reduce th e generally undesired transverse sensitivity of the measuring sensor (1) to pressure, especially pressure changes, and thus improve the accuracy of measurement of the sensor.

Title: Method for milling casting moulds
Inventor: HENTSCHEL BERTRAM
IPC: B22C7/00
Filed: 2002-09-21
Abstract: The invention relates to a method for producing heat-resistant casting moulds from mould materials, especially from moulding sand containing a binding agent, or for producing an inner contour of models or prototypes consisting of plastic, graphite, derived timber products or other millable materials. Large volumes and deep gravures are often obtained, especially during the machining of moulds for the rapid production of prototypes of cast materials. In order to increase the efficiency of the inventive method, in a first step, blocks of mould material are produced in such a way that a dimension thereof corresponds to a mould cavity depth which typically measures up to between 300 and 400 mm.  The inner contour of the mould is then produced in such a way that it has an oversize having a contour which is close to the contour of the inner wall of the mould cavity, using a roughing tool (4) having an effective cutting diameter of between 12 and 35 mm. The mould cavity is then machined by milling the oversize material, following the contour, using a finishing cutter (3) having a diameter-length ratio of between 1:10 and 1:30.
