Patent EP-0205403-A1 (EP)
Inventor: BLACKWELL JOSEPH THOMAS
IPC: C07C209/00
Filed: 1986-06-04
Abstract: A modified novel process for preparing cyclopropylamine from y-butyrolactone is described. The y-butyrolactone ring is cleaved with a hydrohalide in the presence of a novel catalyst comprising an aqueous sulfuric acid solution. The 4-chlorobutyric acid, thus formed is converted into a hindered chlorobutyrate ester. The hindered ester based on secondary and tertiary alkanols of eight or less carbon atoms, is cyclized to form the hindered cyclopropanecarboxylate ester by a novel reaction medium consisting of solid caustic in a water-immiscilbe solvent and a phase transfer catalyst. The hindered cyclopropanecarboxylate ester is ammoniated to form cyclopropanecarboxamide by a novel catalyst comprising an alkyli metal salt of a polyol having hydroxy groups on adjacent carbons. The carboxamide formed in substantially quantitative yields in converted to cyclopropylamine by a modified Hofmann reaction utilizing continuous degradation of the intermediate with simultaneous destillation.

Abstract: The support has at least two laterally arranged support units (9), which each contain a spring element (5), at least one spring plate (8) and at least one rail-type bearing piece (10) which is essentially rectangular in plan view, consists of a rubber-elastic material, and via which the spring plate 8 is supported against the adjacent vehicle part - body (1) or bogie (2). The bearing pieces (10) are each arranged with their long sides oriented transversely to the longitudinal direction (x) of the vehicle. Correspondingly, the spring plates (8) can be inclined in relation to the adjacent body (1) or bogie (2) in each case by a relatively large angle of inclination in the longitudinal direction (x) of the vehicle and by a considerably smaller angle of inclination transversely to the longitudinal direction (x) of the vehicle. When the bogie (2) is rotated relative to the body (1), the spring elements (5) are each deflected to a different extent in the longitudinal direction (x) and the transverse direction (y) of the vehicle. By suitable selection of the ratio of the width (B) to the length (L) of the bearing piece (10), a predetermined ratio of the horizontal spring constants of the relevant support unit (9) acting in the longitudinal direction (x) and the transverse direction (y) of the vehicle can be achieved. By this means, the resistance to turn-out of the support can be influenced within a broad range. <IMAGE>

IPC: A61L2/26
Filed: 1987-08-12
Abstract: A device for testing the presence of air in a steam sterilizer for porous loads, comprising four porous masses (10) each formed from a stack of single rectangular sheets of spun-bonded polypropylene, each mass being contained and enclosed by perforated shrink wrapping film to produce a block of typically some 4 cm in height and typically some 15 cm square. Interposed between the masses (10) are envelopes (13) of a similar material, each containing a thermocouple and conductor leads. The assembled stack is contained by upper and lower end plates (15) and resilient side panels (16) which serve as clamps to compress the stack. When placed in a steam sterilizer under operating conditions, the device serves to test the accuracy and efficiency of the sterilizer by taking accurate temperature readings from the thermocouples placed at the different heights, and by comparing these readings to the temperature in the condensate drain passage of the sterilizer.

Abstract: The invention proposes an internal combustion engine which is distinguished by the fact that the compression chamber of the cylinder (11) is divided into a chamber (16) filled with an ignitable mixture which ignites first and a further, secondary chamber (24) (air cushion) filled with air or a lean mixture, as soon as the piston top (17) of a step piston (12) passes the lower edge (35) of a cylinder ring (18) in which the secondary chamber (24) containing the air cushion is provided, i.e. shortly before the completion of compression and before ignition in the combustion chamber (16) a pronounced swirling of the compressed mixture being achieved by means of airstreams (jets) blown in via air nozzles and/or the piston neck gap, it being possible, in addition, for fresh air to be blown in in the region of the piston neck (21) and the piston shoulder (22) via an air feed duct (30) in the region of the bottom dead centre of the piston (12) in order to obtain a stratified charging effect in which pure air is taken in first and then an ignitable mixture, the compression chamber containing the compressed mixture being designed as an open combustion chamber for the purpose of low consumption values. After ignition, when the piston (12) exposes the lower edge (35) of the cylinder ring (18), air or a lean mixture flows out of the air cushion into the burning gases in the cylinder (11), producing a pronounced swirling effect, with the result that low-pollutant combustion is promoted by the large excess of air. <IMAGE>
