Title: Packaging films for soft cheese - with coextruded plastic film bonded to waxed paper, have controlled permeability to allow ripening
IPC: B32B27/08
Filed: 1976-01-13
Abstract: Packing film for soft cheese comprises a plastic film bonded spotwise or linewise to a sheet of waxed paper. The plastic film formed from co-extruded film of different thermoplastics such that the film has a water vapour permeability of 50 g/m2/day under 'tropical' conditions, an O2 permeability of 350 cm3/m2/day and a CO2 permeability of 500 cm3/m2/day. Pref. film comprises an 8 mu thick nylon-6 film, a 3 mu thick ionomer film and a 16 mu thick low density polyethylene film. The polyethylene component may be whitened with 5 wt % TiO2. The plastics part of the composite wrapping gives the correct balance of gas permeabilities to allow absorption of O2 and release of CO2 and water vapour during the ripening stage in the pack, whilst preventing excessive loss of moisture during storage s that wt. loss and drying out of the product occur. The waxed paper part is packed in contact with the cheese to prevent sticking of the cheese to the film. The packaged cheese can be stred for longer periods than when using waxed paper alone, while the ripening of the cheese (e.g. brie, coulommiers, camembert, bonbons, etc.) is not hampered.

Title: Anchorage and clasp for vehicle safety belt - has end gripped between arms formed directly in anchorage strip and opened by button to release
IPC: A44B11/25
Filed: 1976-01-20
Abstract: The anchorage is a rigid metal strip, twisted through 90 deg. to flex in all directions and bolted to the vehicle bodywork. Its other end is enlarged and split, giving spring arms, one each side of a gap. It is encased in a housing to form a clasp. The end of the safety belt has a flat tongue, a pin passing through its thickness and headed both sides. This tongue is pushed between the spring arms, the pin locking in holes. To release the anchorage, a spring loaded button on the housing is pressed down; this opens the arms to release the pin.

Inventor: FILLOL BERNARD
IPC: G01B9/02
Filed: 1976-12-23
Abstract: An interferometer for measurement of displacement utilises circular polarisation of the two beams in opposing directions. The beams are processed and analysed to obtain two fringing signals with a phase difference of 90 deg. The average intensity is zero. Monochromatic light (1a) from a laser (1) is divided (2) into a measurement beam (3) directed towards a moving reflector (4) and into a reference beam (5) directed towards a fixed reflector (6). Returned beams (3a, 5a) pass into a divider (2) to become a single beam (7). This is directed by a mirror (8) into a divider (9) and the beams (21, 12) are detected (20, 13, 11) after analysis (16, 15, 22).

Title: Optical smoke detector using pulsed light beam detector - has triggered monostable system and filter circuit to suppress noise
IPC: H03K17/94
Filed: 1977-10-25
Abstract: A smoke detector circuit uses a pulsed light beam generator and detector and an amplifier, monostable multivibrator and filter circuit which are insensitive to the disturbance effects normally occurring in such equipment. A pulsed light beam generator using an optical diode generates a beam of light which falls on a receiver circuit via a test area to which the smoke to be detected has access. The receiver circuit comprises a preamplifier threshold detector, monostable multivibrator, resistance capacitance low pass filter circuit a discharge circuit and an output alarm stage. The preamplifier stage is arranged to produce small pulses when no smoke and higher amplitude pulses where smoke is present in the test area. These different levels are differentiated between by transistorised circuits.
