Patent FR-2259836-A1 (FR)
IPC: C12N11/08
Filed: 1974-02-04
Abstract: The new, bromocyan-activated, hydrophilic, polymeric gel in dried form is used as a carrier for biologically active compounds, for example enzymes, coenzymes, enzyme inhibitors, antibodies, antigens, hormones, immunoactive compounds and antibiotics. First hydroxyalkyl methacrylate or acrylate or oligo- or polyglycol monomethacrylate or monoacrylate is suspension-copolymerised with crosslinking monomers, for example with a polyhydric alcohol which has been polyesterified with acrylic or methacrylic acid, with a bisacrylamide or with divinylbenzene, to prepare a hydroxyl-containing, hydrophilic, macroporous gel. The porosity thereof is preferably such that molecules having a molecular weight of up to about 300,000 can penetrate into the gel. The gel is activated with bromocyan and then gently dehydrated, for example with organic solvent. The new gel has improved mechanical properties compared with conventional carriers. This makes it possible to use the material even in large-scale apparatus.

Title: Multi piece tool for calibrating the profiles of bottle tops - with optical indication for several dimensions checked simultaneously
Inventor: FLAMAND GUY
IPC: H03H17/00
Filed: 1974-06-07
Abstract: A tool for checking the geometry of an opening in a container in respect of several parameters simultaneously, viz. for the top of a bottle, the bore, ovality, concentricity, dia. and height of the mouth and neck. Basically, the tool comprises a probe mounted in a stiff barrel. The probe is fitted with a head ending in a series of stepped levels of decreasing dias. which progress from larger than the required bare to smaller. A series of concentric sleeves are sized with plane or stepped ends to bear on the top of the neck, the lip of the neck and the shoulders of the bottle respectively. All the concentric components are drilled at levels which will align if the dimensions supporting the probe and the sleeves are all correct. Alignment of the drilled passages is checked by a light beam; if any component is out of line, the beam is interrupted, indicating a defective shape. If the bottle neck is oversize or oval, the probe or sleeve will rest on a stepped face and thus be supported with its passage out of alignment. The tool is used for calibrating the mouths of bottles, moulded containers, etc. More reliable and compact than systems for aligning the components at a series of different positions with several independent heads each checking one dimensions parameter (or successively aligning a series of mobile heads with a stationary bottle).

Title: 3 - AC to DC voltage convertor
Inventor: GENEVRAY JEAN-LOUIS
IPC: H02M3/335
Filed: 1975-01-20
Abstract: This DC to DC voltage convertor uses a comparator circuit for its control. One input of the comparator is from a sawtooth generator and the other is a sample of the output. The comparator produces a square wave output to drive a voltage converting transformer. The output of the transformer is rectified and smoothed. The output voltage sample is taken from a divider chain and may be connected to the comparator by a field-effect transistor. The design gives a regulated output for medium and low power convertors.

Title: Telescopic vehicle shock absorber - has spiral preloading spring surrounding damper body with adjustable mounting
IPC: B60G17/02
Filed: 1975-07-18
Abstract: The spiral spring (15) surrounds the shock absorber body (10) of the damper cylinder and is attached (12) in the usual way to one end of the damper piston rod (12) close to a mounting bush (13). The other end of the spring is held by two half shells (20, 21) which when clamped together by screws (24) grip the body of the damper. The outside surface of the shells is formed into a coarse threat to fit the spring and at the lower and of the thread, an indentation (19) is formed. This indentation receives the inwardly turned end (16) of the spring, providing a position location. By slackening the clamp screws, the shells can be adjusted to grip the body in any position and thus set the spring load.
