Patent FR-2490794-A1 (FR)
Title: Cooler for preservation of cadaver - uses metal slab made up as two dissimilar metal junctions, and low voltage DC supply which creates cooling using peltier effect
IPC: A61G17/00
Filed: 1981-07-28
Abstract: The appts. has a metal plate which is cooled using the Peltier effect. The metal junctions are formed as a slab whose lower surface is cooled and upper surface heated by the Peltier effect. The slab is supplied by a low voltage direct current obtained by rectification of AC voltage transformed down from the AC mains voltage. A temp. sensor may be incorporated to switch the current, and a heat exchanger may be fitted to the upper (warm) junction to extract the heat. This may be either fan or circulating fluid cooled. Multiple units may be connected in parallel from the same electrical supply. The body is enclosed in a sleeping bag type container having very low thermal conductivity.

Title: TV signal transmission system for optical fibre cable - uses passband filters for sound and video channel multiplexing in transmitter and receiver
Inventor: JARRET BERTRAND
IPC: H04N7/22
Filed: 1981-08-12
Abstract: The system includes a transmission module (10) which contains a frequency modulator (11) for the sound channel (S) to limit intermode effects in the video band. The modulator output and the video signal (V) are applied to a multiplexer (12) containing passband filters (14,13) for the respective channels. The multiplexer output is applied to a latching circuit (19) to ensure that the photodiode (17) is operated over the linear part of the transfer function characteristic. A voltage to current converter (18) drives the photodiode from the multiplexer output to transmit the signals along an optical fibre (30). At the receiver a photodiode output is applied to a demultiplexer containing passband filters to separate the sound and video signals. The sound channel signal output is demodulated.

Title: Detonator circuit for anti-tank mine - includes acoustic detectors analysing frequencies of received sound for identification using pass-band filters, A=D converters and memories
Inventor: STUETZLE DIETMAR
IPC: F42C11/00
Filed: 1981-12-02
Abstract: The firing circuit for an anti-tank mine includes an acoustic detector after which is mounted a pass-band filter and an amplifier, and a detector to identify the object. Mounted in parallel with the amplifier (7) there are a number of pass-band filters (9-14) each of which is adjusted to a particular range of frequencies. The amplitudes of the outputs of the pass-band filters are converted into digital form by a converter (22). They are then fed to a comparison circuit (23) for comparison with memorised values. When the majority of the signals coincide with the memorised values, the detector is free to release a detection signal. The frequencies covered by the device may range from several Hz to several kHz, the range being covered in octaves. The amplitudes provided by the filters may be explored by a multiplexer.

Title: Socket fabrication method for banana type plugs - uses axially bored cylindrical rod, into which elastic inward bending cage is inserted
Inventor: ANDRE CLAUDE
IPC: H01R13/187
Filed: 1982-03-02
Abstract: The cylindrical socket can be made simply to give a contact which has the optimum amount of insertion and extraction frictional force. A cylindrical rod (1) is centrally drilled to give an axial bore (3). The rim of the opening has a thinned section (10) to assist burring-over of the edge. A concave barrell-shaped cage (4) made of a single pressing of copper alloy sheet (6) has inwardly bending longitudinal strips and is rolled into cylindrical form. The cage allows radial elastic deformation and, when inserted into the bore, expands to the bore internal diameter. Once inserted, the rim of bore is rolled over to form a lip which retains the cage inside the bore. The socket can be made from a length of tube which is first pinched to form a neck to form a stop for the plug before the cage is inserted.

Patent FR-2518285-A1 (FR)
Inventor: KREFT HANS-DIETRICH
IPC: G07C9/28
Filed: 1982-12-15
Abstract: A device for inductive identification of an information item, particularly of access control consisting of an inductive electronic lock and key part, in which, when the key part approaches the lock part, its oscillator section oscillates with a high frequency, this oscillation is picked up by the key section and, modulated with a frequency or pulse pattern used as key code, is transmitted back to the lock section and is processed further by the lock-side receiving and recognition device. The energy is transmitted forward and back between lock and key section by means of wave coupling by means of antenna coils, an inductively coupled synchronisation switch being established by the fact that a changed signal pattern is caused at the coil at the lock end, for example by means of a more or less complete short circuit at the coil at the key end, or by the impression of an energy onto the latter.

Title: Method for fibre-optic temperature measurement, sensor and measurement system employing this method
IPC: G01K11/32
Filed: 1983-07-07
Abstract: The invention relates to a method for fibre-optic temperature measurement, a sensor and a measurement system employing this method. The method according to the invention consists in coupling the mode between the core and the cladding of an optical fibre such that the curve of the luminous power transmitted by this fibre as a function of the temperature P = f(t) has at least one minimum (Ps) for a threshold temperature (ts). This method employs a fibre having a W-shaped profile, which has a locally abraided part filled with a coupling material whose refractive index varies more rapidly with temperature than that of the other constituents of the fibre. The invention applies to any temperature measurement devices, with the possibility of an alarm, in particular in cases where access is difficult or dangerous.

Abstract: The device detects what is known as a "hot spot", having a temperature several degrees above that of the surroundings, both by night and day and during any weather conditions. The device consists of a convergent optical system 2 which focuses a beam of radiation coming from the field of observation on to a modulating grid 6. This grid comprises alternately opaque and transparent zones 61, 62 extending radially. An infra-red detector 7 is placed behind the grid. The modulating grid 6 is fixed and the zones 61, 62 have indented edges forming chevrons. The beam is reflected onto the grid by a rotating reflector 3 whose reflecting surface is inclined to the optical axis 8 of the optical system. The device is particularly intended to supply a warning signal to an image-intensifying instrument for night viewing.
