Patent FR-2630987-A1 (FR)
Title: Circuit intended to be arranged between a pneumatic pipe and a brake cylinder of a rail vehicle for controlling the pressure prevailing in the said cylinder and spill valve for this circuit
Inventor: CHAPPEZ ROBERT
IPC: B60T13/40
Filed: 1988-05-04
Abstract: A circuit intended to be arranged between a pneumatic pipe 1 and a brake cylinder 2 of a rail vehicle for controlling the pressure prevailing in the said cylinder and a spill valve 10 for this circuit. During normal operation, the circuit is controlled by an electrical line by means of an electropneumatic device 39. If electricity is absent, the circuit can be controlled by the pipe 1 feeding the pneumatic appliances of the train, thus making it possible to avoid the pneumatic brake-control pipe which conventionally duplicates the pneumatic feed pipe.
Patent FR-2631451-A1 (FR)
Title: Locating epitope(s) in protein reactive with monoclonal antibodies - by testing immuno-reactivity of truncated polypeptide(s) translated from fragments of C-DNA
Inventor: MILGROM EDWIN
IPC: G01N33/68
Filed: 1988-05-13
Abstract: Process for locating the interaction site between a specific protein (I) and at least one monoclonal antibody (MAb) which recognises the entire protein comprises: (1) either isolating a DNA fragment which includes a cDNA encoding (I), under control of a transcriptional promoter, plus the elements necessary for in vitro translation of corresp.  RNA, or prepg. a mixt. of fragments of such DNA contg. differently-sized portions of the cDNA under control of the same promoter; (2) transcribing the cDNA, then in vitro translation of the resulting RNA into polypeptides (Ia) in a cell-free medium; (3) testing (Ia) for reaction with specific MAb; (4) sepg. (Ia) according to size (this step may precede reaction with MAb); (5) identifying the largest and smallest (Ia) recognised by MAb; and (6) identifying the essential element of t e-epitope specific for MAb in the smallest (Ia); it consists of the C-terminal sequence of one or more amino acids still present in the smallest (Ia) recognised by (Ia) but missing from the largest (Ia) not recognised. Also new is a support (pref. a gel) contg. labelled, truncated proteins, pref. in order of size, sepd. from each other and fixed to the support in such a way that they can still undergo immunological reaction with specific MAb which recognise the intact protein (from which all (II) are derived) or its homologues. USE/ADVANTAGE - The method is used to define immunogenic and functional domains of proteins; for in vitro mutagenesis testing, and for mapping biological molecules (e.g. receptors or antigens). Compared with known methods, this method is simpler and requires fewer steps.

Title: Electromagnetic lock capable of being closed and locked or unlocked and opened manually by means of a key
Inventor: BERNARD NOEL
IPC: E05B47/02
Filed: 1989-05-24
Abstract: The lock bolts 3 can move between a lock closed position and a lock open position. A bolt 15 can move, under the action of a key-operated cylinder 22, between a first position in which the lock bolts 3 are blocked mechanically in the lock closed position, and a second position in which the electromagnetic operation of the lock is allowed by means of solenoids 7. Means 14, 35 couple the bolt 15 and the lock bolts 3 when the bolt passes from its second position to its first position and when the lock bolts 3 are initially in the lock open position, or in any case when the bolt 15 arrives in the first position while the lock bolts are in the closed position. A blocking catch 46 then locks the bolt 15 and therefore the lock bolts 3 in the lock closed position. For operation in the other direction, a key web 31 driven by the cylinder 22 pushes back the catch 46, then the bolt 15 entrains the lock bolts 3 into the lock open position in which the means 14, 35 are uncoupled, after which electromagnetic operation is possible. Use in particular for controlling the doors of automatic or semi-automatic lock chambers (airlocks).
