Title: Arrangement for controlling air flow to breathing flap or mask
Inventor: VERKOEYEN CONRARDUS JOHANNES J
IPC: A62B9/02
Filed: 1996-11-04
Granted: 1998-05-08
Abstract: The arrangement consists of five parts, a metal plug-in nipple, a control knob a plastic housing with cast-on core with various bores, and a damper or filter space with hose. Compressed air is fed to the core via the metal nipple. The control knob is used to mix-in air The centreline of the knob is in line with the centrelines of the nipple, housing and hose. The safe volume of air flow is independent from the position of the knob. The knob has a spiral cut-out, on the inside, which interconnects two by-pass openings. The sound level of the unit at 6 Bar, measured at 10cm, is no more than 65 dBa. The sound damper can be replaced by a carbon filter

Title: Burner-driven coaxial, thermo-acoustic heat engine involves heat fed by electro-magnetic radiation from primary fossil-fuel energy source, so that on high temperature side of regenerator a gas-gas heat exchanger is not necessary
Inventor: BLOK CORNELIS MARIA DE
IPC: F02G1/043
Filed: 2002-09-06
Granted: 2004-03-10
Abstract: The burner-driven, coaxial, thermo-acoustic heat engine involves heat fed by electro-magnetic radiation from a primary fossil-fuel energy source, so that on the high temperature side of the regenerator (4) a gas-gas heat exchanger is superfluous. As radiation source a recuperative bar burner is used which via a primary energy source is maintained at a high temperature. The regenerator is coaxial around the burner so that as much radiation energy as possible is absorbed. Through the cylindrical shape of the regeneration burner a great pressure difference can be established between the flue gases and the thermo-acoustic process. The regenerative, thermo-acoustic energy converter is located in a housing (1), which via a narrowed tube (2) is coupled with a second housing (3) in which is a second regenerative thermo-coaxial energy converter, preferably configurated as a heat pump. The first converter consists of a regenerator (4) clamped between two heat exchangers (5,6).

Granted: 1994-03-30
Abstract: Использование: в машиностроении. Сущность изобретения: в реверс-редукторе при нейтральном положении рычага ведомый вал неподвижен. От двигателя крутящий момент через ведущий вал передается ступице, барабанам, упорным дискам и масляному насосу через шестерни. Масляный насос всасывает масло из нижней части корпуса и перекачивает его обратно через охладитель, клапан. Смазка всех пар трения обеспечивается разбрызгиванием и через систему жиклеров. При переводе рычага в положение "передний ход" насос прокачивает масло через охладитель, фильтр, трубопровод к крышке с блоком управления. Через каналы в крышке с блоком управления, ведущем вале по радиальному зазору между распорной втулкой и ведущим валом и сверлением в ступице масло подается под нажимной диск муфты прямого хода и перемещает его в осевом направлении. Одновременно под действием давления масла плунжер перемещается в осевом направлении вслед за нажимным диском и перекрывает отверстие в ступице, отсекая утечку масла из-под нажимного диска. Нажимной диск сжимает пакет дисков трения. В результате крутящий момент от двигателя передается ведомому валу через ведущий вал, ступицу, ведущий барабан, сжатый пакет дисков трения муфты переходного хода, ведомую ступицу, ведущую и ведомую шестерни переднего хода. При возвращении рычага в нейтральное положение отсекается подача масла под нажимной диск. Одновременно канал подвода масла к последнему соединяется с каналом слива масла в масляную ванну корпуса. Нажимной диск под действием пружин перемещается в обратном направлении, одновременно перемещается плунжер. Плунжер открывает отверстие в ступице, что ускоряет отвод масла и возвращение нажимного диска в исходное положение. Пакет дисков трения муфты переднего хода разжимается. Ведомый вал останавливается. При переводе рычага в положение "задний ход" масляный насос подает масло через охладитель, масляный фильтр, трубопровод, каналы в крышке с блоком управления, центральное отверстие в ведущем валу и отверстие в ступице под нажимной диск муфты заднего хода. 5 ил.
