Title: Corticosteroids microbiological 1,2-dehydrogenation
IPC: C12P33/02
Filed: 1970-09-14
Granted: 1972-04-28
Abstract: In a process for 1,2-dehydrogenation of corticosteroids with Arthrobacter or Corynebacterium species involving enzyme-induction subsequent to cultivation but prior to dehydrogenation, the induction of the steroid 1,2-dehydrogenase is begun by addition of 0.02-0.2 mg/ml of a steroid of the androstane or pregnane series only after the growth of the bacteria in the stationary phase of the culture, an amount of a C- and /or N-source such as to give a 0.01-0.1% concentration being simultaneously added to the culture so as to give rise to a secondary growth. A 1,2-satd. corticosteroid is added to the resulting highly active culture (which can be diluted before the addition), the dehydrogenation and the isolation of the product being effected in a conventional manner. The new method of induction gives very high enzyme levels, and the dehydrogenation proceeds extremely rapidly and is unaccompanied by steroid degradation or reduction.

Patent FR-2192674-A5 (FR)
Title: Stuffing box type seal with elastic core - for sealing walls or bulkheads traversed by power or communication cables
IPC: F16J15/20
Filed: 1972-07-13
Granted: 1974-02-08
Abstract: Joints with a hollow housing with a internal flange for locating a tubular elastic element having two thick annular end zones linked by a relatively thin web at the room of a 'U' section annular channel where the web defines a minimum bore for the axial passage through the seal. After installation, the elastic core is compressed longitudinally to close the annular channel and displace the web radially inwards against the surface of the component traversing the internal passage. One face of the elastic element may be recessed to accept an annular metal press plate. If small relative to the housing, the core may be backed up by an ancillary annular plate to prevent excessive distortion away from the compression device. Core may be made of e.g. 'neoprene' (RTM-polychloroprene). It is used to provide a dry, presse tight seal for powder, control or communication cables traversing structural walls or hazard partitions, and can adapt to a wider range of cable size than a conventional external radial compression ring seal.

Title: Film centering apparatus for stretch film packaging machine has pairs of driven parallel rollers ahead of conveyor belts
Inventor: DESSOY JEAN-LUC
IPC: B65B59/00
Filed: 2000-05-25
Abstract: The centering apparatus is for use on a packaging machine which wraps products of different dimensions in stretch film delivered by parallel conveyor belts (C1, C2) set one above the other and gripping the film bit its edges while controlled by a processor (3) and motor (2). It consists of first and second pairs of parallel rollers (4, 5) situated before the conveyor belts and designed to move the film as it comes off an oscillating arm (10) located after the film roll (B). The rollers normally turn in the opposite direction to the film's movement, and have a cutter (12) between the two pairs. Between the cutter and second pair of rollers there is an idling roller (16) and a film accumulator, e.g. in the form of an oscillating arm (17) controlled by an electric motor (22) and servo-mechanism (19 - 21, 23). The apparatus also includes an opto-electronic barrier system (24, 25) to measure the dimensions of the articles to be wrapped and adjust the film quantity accordingly.
