Patent DE-3727307-C1 (DE)
Title: 4-stroke internal combustion engine with separately controlled inlet and exhaust
Inventor: JURACK KURT
IPC: F02F1/42
Filed: 1987-08-17
Granted: 1989-02-23
Abstract: The invention produces an up to 100% improvement of the volumetric efficiency for the inlet of a spark ignition and diesel engine without using a plurality of valves for each working piston. This improvement on a currently used valve is achieved by means of an annular valve for the inlet. In addition, the exhaust valve, heated until it is red hot, is dispensed with and petrol with a lower octane rating can thereby be used without manifestations of knocking. The annular valve used (Fig. 2) exposes a plurality of passages on the circumference so that a high volumetric efficiency is achieved. The opening and closing of the passages by the annular valve is performed through an oscillating movement and can be achieved by means of a cam plate or an eccentric. These types of drive also check the pressures which occur on the baseplate of the annular valve. <IMAGE>

Title: Centrifuge
IPC: B04B11/04
Filed: 1988-07-23
Granted: 1989-09-28
Abstract: A centrifuge (1) for de-oiling and/or drying small parts has, in the interior of its drum (2), as mountings for rectangular or square boxes (3) to be inserted, supporting walls (5) which can be displaced and fixed in the radial direction, so that a very accurate adaptation to the respectively inserted box (3) and thus prevention of deformation of its walls (4) is possible. The displacement takes place expediently via mechanically displaceable wedges in order to be able to receive centrifugal forces occurring during centrifuging well and, nevertheless, to be able to make the displacement and locking very simple in terms of construction (Figure 1). <IMAGE>

Title: Process for producing a sprayable, porous insulating material for underground mining
IPC: C08J9/00
Filed: 1989-04-08
Granted: 1990-10-11
Abstract: To produce a sprayable, porous insulating material for underground mining, a process is proposed in which flowable (free-flowing) foam medium in the form of phenol resol resin mixed with aluminium hydroxide is brought to the site of use, preferably being pumped via pipes. On site, the blowing agent (foaming agent) and hardener, especially in the form of toluenesulphonic acid, is then added so that the insulating material foams, developing its insulating action, and can be used at the same time for filling hollow spaces or for application to surfaces to be insulated without further measures being necessary. The insulating material has a bulk density between 30 and 500 kg/m<3>, with this being able to be varied so that favourable matching to the respective areas of use is possible. In addition, the insulating material has a high fire resistance and on combustion liberates neither smoke nor toxic gases. Incorporation of glass felt (nonwoven) or similar material can further change, i.e. increase, the compressive strength and the fire resistance time. The insulating material thus serves not only as heat insulation but at the same time as fire protection insulation and, in addition, to fill hollow spaces in such a way that hazardous gases cannot accumulate there, but at the same time sufficient support function is achieved. <IMAGE>

Patent DE-4310834-C1 (DE)
Inventor: ZACH WOLFGANG
IPC: A61F2/00
Filed: 1993-04-02
Granted: 1994-10-13
Abstract: The impacting device is used to manipulate the stem of endoprostheses made or steel or a fibre composite having a smooth conical or cylindrical proximal end. For anchorage, conventional impacting devices require a positive connection to the prosthesis end or else their bulky construction restricts their use in a narrow wound. The novel device is exclusively connected to the prosthesis end by frictional engagement and can even be handled easily in a narrow wound due to its extremely compact design. The cylindrical grip head (2) with the clamping ring (8) mounted therein is attached to the prosthetic cone (16) and braced by cheese head screws (7). At the same time, the clamping ring (8) is radially compressed via the double cone (9), and the frictional engagement with the prosthetic cone (16) is thereby produced. The axially parallel arrangement of the cylindrical bolt (13) relative to the axis of the prosthetic stem (18) and the slight coaxial offset of the two axes permit insertion and extraction of the prosthesis (1) virtually without transverse forces and in a manner that is not damaging for bone. <IMAGE>

Title: Shaft sealing ring
Inventor: HEINE STEFFEN DR
IPC: F16J15/3228
Filed: 1993-07-21
Granted: 1994-11-17
Abstract: A shaft sealing ring with a housing, between the legs of which at least two discs of polymeric material are clamped, has a protective lip on one disc and a sealing lip on the other. The inside diameters of the discs prior to installation of the shaft sealing ring are smaller than the outside diameter of the shaft to be sealed. Positioned between the two discs is an expander ring which ensures that the disc with the sealing lip bends over in the opposite direction to the disc with the protective lip and, by virtue of its consistency, leads to a lubricating effect of the contact point between the sealing lip and the shaft when the operating temperature of the shaft sealing ring is reached.

Filed: 1996-10-30
Granted: 1998-05-08
Abstract: The receiver on receipt of the signal from the transmitter emits a signal with the same frequency as the transmitted signal and the sender (1) determines the phase difference between the transmitted and received signal. When a predetermined adjustable value is exceeded, the transmitter generates a warning signal (10). Moreover, the transmitter (1) determines the number of signal periods between those transmitted by the transmitter and those received by the transmitter.

Abstract: Изобретение касается вращающегося решетчатого охладителя для непрерывного и быстрого охлаждения клинкера или аналогичных продуктов. Сущность изобретения: охладитель состоит из цилиндрической трубчатой решетки, которой сообщается постоянное вращательное движение с регулируемой скоростью вокруг продольной оси симметрии и которая несколько наклонена по отношению к горизонтальной плоскости. Внешняя цилиндрическая поверхность вращающейся решетки, совершающей вращательное движение, постоянно проходит мимо внутренней части охладителя, откуда поступает постоянный поток холодного воздуха из камер под давлением, расположенных вдоль всей длины вращающейся решетки. Клинкер, приготовленный в печи для обжига при очень высокой температуре, постоянно подается через подающий канал в более высокорасположенную часть внутренней цилиндрической поверхности вращающейся решетки через пластины охлаждения. Далее масса горячего клинкера, распределенная в продольном направлении, подвергается непрерывному турбулентному вращательному движению, создаваемому вращением вращающейся решетки, и одновременному медленному аксиальному перемещению по направлению к нижней части охладителя, возникающему благодаря некоторому наклону его оси симметрии. Поток холодного воздуха под давлением, который проходит через щели в пластинах охлаждения , быстро охлаждает клинкер и направляется по подающему каналу в систему нагрева печи для обжига для более полного использования его тепловой энергии в камере сгорания печи для обжига. Охлажденный клинкер, достигший желаемой температуры, постепенно выводится под действием собственного веса через щели в пластинах охлаждения (тонкий клинкер), или в оконечной части вращающейся решетки через отверстия между стержнями сортировки, или через дробилку (большие куски, удерживаемые сортирующими стержнями) и собирается на ячеистом конвейере, расположенном под охладителем, который переносит клинкер в хранилище. 5 з. п. ф-лы, 5 ил.
