Title: Device for the protection of objects or body parts against vibrations
Inventor: KARALL GERHARD
IPC: A41D13/00
Filed: 1999-07-21
Abstract: There is disclosed a device for the protection of objects or body parts against vibrations, in particular a vibration-damping glove or antivibration glove, including at least one vibration-damping  layer. In order to realize such a device, which causes noticeable damping of vibrations even in the low-frequency range of vibrations (31.5 to 200 Hz) and, in addition, remains maneuverable to the largest extent possible, at least one vibration-damping layer, on its surface facing away from the object or body part to be protected, includes indents for decoupling movements in at least one direction in the plane of that surface.  The indents, on the one hand, cause the vibrations oriented in the plane of the surface to be deflected into the interior of the layer, thereby enhancing the vibration-damping effect, in particular in the low-frequency range. On the other hand, a high degree of movability of the vibration-damping layer, and hence of the overall device, is ensured by the indents.

Patent CA-2285958-A1 (CA)
Inventor: PRADEL LUIS ADOLFO VELLOSO
IPC: B65D88/40
Filed: 1998-04-01
Abstract: The present invention relates to a device which is used in the floating roofs of tanks for storing liquids and is intended to prevent the formation of a vacuum between the stored liquid and the floating roof (5). More particularly, the device of the invention is intended for a liquid storage tank which has operating heights which are much lower than the maintenance height. There are two possible ways in which the device of the invention can operate. When the floating roof (5) is in operating mode and reaches its minimum operating height (Figure 2), a lower shaft stop (10) of a sliding shaft of the valve comes against a lower stop (8) of the body (2) of the device, causing the device (30) to open. When the floating roof (5) is placed in the maintenance mode, use is made of a locking pin (4) for rigidly fastening the sliding shaft (3) to the body (2) of the device (30), which enables the assembly to open when the floating roof reaches the maintenance height.

Title: Parathyroid hypertensive factor
Inventor: LEWANCZUK RICHARD Z
IPC: A61K31/59
Filed: 1990-03-22
Abstract: A new circulating factor from the parathyroid gland of some hypertensive mammals has been isolated and characterized. Polyclonal and monoclonal antibodies raised against this factor are usable as a screen for the presence of the factor. The factor is involved in the control of calcium uptake in cells. Hypertensive mammals may be treated to lower mean blood pressure by administering a calcium channel blocking agent together with one or both of a calcium supplement and Vitamin D. The hypotensive effect of this combination is synergistic and the dose response is more predictable than the administration of any of these agents singly.
