Patent EP-0074954-A4 (EP)
Title: Sound attenuator.
Inventor: HOY ROBERT W
IPC: F24F13/24
Filed: 1981-12-03
Abstract: Sound attenuators used in ventilation, and in particular, for positioning adjacent ventilation fans that produce noise and vibration in such industrial areas as mines or factories. Known sound attenuators for such purposes are normally constructed of bulky and heavy material such as perforated metal and solid metal thereby tending to be easily dented and damaged and susceptible to corrosion. These attenuators also use sound absorbing material that if wetted renders the attenuator substantially useless wherein the attenuator must be replaced. Considering such problems as noted, a sound attenuator is provided suitable for use in reducing noise produced by axial flow fans used in industrial environs such as mines and factories. The sound attenuator comprising concentric inner and outer tubular members (10, 12) having sound absorbing material (14) positioned therebetween. The inner tubular member comprises a lattice (20) of reinforcing strand material (22) coated with solidified resin (24) wherein the strand material is formed in opposed generally helical patterns to provide the lattice.

Patent EP-0277961-A4 (EP)
Title: Capacitor circuit interruption.
Inventor: BENTLEY JEFFREY A
IPC: H02H7/16
Filed: 1987-06-04
Abstract: A circuit interrupter in electrical capacitors is activated by an interruption mechanism that moves an actuator (44) in response to a predetermined physical condition within the capacitor to cause electrical disconnection. The actuator has a range of motions through a limited number of stable positions and is mechanically pre-biased to move towards one of the stable positions when not already in one of the stable positions. Previously, pressure sensitive interrupters would be reconnected when the cover and terminals settled back due to pressure drop which could cause arcing. The present capacitor (12) is quickly and effectively disconnected when pressure builds up and stably remains in its popped up position to reduce the chance of reconnection. Capacitor terminals (18 and 20) are mounted on the actuator which is attached to a housing (54) by hinge regions (58) which provide a stable position upon build up of a pressure.

Patent EP-0610206-A4 (EP)
Title: Intubation device.
Inventor: GARTH GEOFFREY C
IPC: A61M16/04
Filed: 1992-05-07
Abstract: An intubation device and a method of intubating a patient with an endotracheal tube is disclosed. The device comprises a housing and a flexible, tubular sheath having one end connected to the housing and a free end extending away from it. The sheath, which is adapted to fit within the endotracheal tube, also has a special light at the end of the sheath's free end for selectively providing illumination. In use, the sheath is inserted into the endotracheal tube until the light is at the end of the distal end of the tube. A clamp on the intubation device then clamps the endotracheal tube to the housing to prevent relative movement between the tube and the sheath. A tube stop is then slid along the sheath into abutting contact with the proximal end of the endotracheal tube to identify the location on the sheath corresponding to the proximal end of the tube. When the tube is properly positioned in the patient, the light will create a distinct glow visible to an observer in the area of the sternal notch. Thus, when it is desired to confirm or recheck placement of the endotracheal tube in the patient, the sheath may be simply inserted into the tube until the proximal end of the tube contacts the tube stop. The device also includes a trocar wire for insertion into the sheath to provide added stiffness.

Abstract: La présente invention concerne une structure souple de pose sur fond sous-marin (1, 3, 4) qui est achevée lorsqu'elle est déposée sur un fond sous-marin ayant un renforcement ou un renforcement accompagné d'une légère excavation. Cette structure comporte une pluralité de réservoirs de ballastage (12) à volume d'eau librement réglable. Il en résulte que le poids total comprenant le poids d'eau dans les réservoirs de ballastage (12) est supérieur au poids de flottabilité assurant le repos sur le fond. En effet, même si la flottabilité se modifie, il ne se produit pas d'affaissement de la structure sur le fond. En outre, la structure est déposée sur le fond de l'eau en respectant des conditions qui font que le volume d'eau dans les réservoirs de ballastage (12) est soumis à une régulation qui garantit que lorsqu'elle est posée sur le fond, la structure subit une pression adéquate de contact avec le fond, laquelle pression résiste à la déformation imputable à une force horizontale.
