Patent FR-2337952-A1 (FR)
Title: In:line electrical connector with but connected contacts - is coupled by single axial movement and retained by radially biased ball bearings
IPC: H01R13/627
Filed: 1976-01-09
Abstract: The electrical connector has free and fixed parts carrying sprung or fixed electrodes or pins such that as the two are mated contact is established. Contact is maintained by one contact being spring loaded and butted against the second contact. The connector is designed to allow connection purely by an axial movement of the free part rather than a push and twist action. Correct location of the two parts is established by one or more radial key elements and maintenance of coupling is by ball bearings moving between separate rest positions for the coupled and uncoupled states against the pressure of circumferential springs.

Title: Cleaning machine for vegetables like asparagus, carrots, leeks etc. - which brushes and washes before cutting and does not cause bruising
IPC: A23N12/02
Filed: 1976-01-20
Abstract: The vegetables are passed through the nip of a pair of cylindrical brushes rotating at different speeds in opposite directions on parallel axes which are adjustably spaced. Washing liquid is sprayed on to both brushes from sparge pipes parallel to the axes of the brushes. Vegetables drop from the brushes into the upstream end of a wash tank which pref. delivers at the other end to a cutting and/or trimming table. The liq. supplied to the sparge pipes is pref. water dosed with cleaning agents and/or preserving additives. Really thorough, mechanised cleaning withut bruising or breaking is achieved. Cutting takes place after cleaning so cut surfaces do not become contaminated with engrained sand, grit etc. Cleaned vegetables have attractive, smooth appearance.

Patent FR-2335245-A1 (FR)
Inventor: MASCHER WERNER
IPC: A62B23/04
Filed: 1976-12-14
Abstract: A plurality of filters are used which each contain an oxygen-releasing and carbon-dioxide-binding and a moisture-binding chemical substance. Control of the moisture load of the oxygen-releasing substance is achieved by a moisture-binding agent at one end of the filter. The room air, depending on its moisture, is passed in one or other direction through the filter. The working lives of the individual filters overlap by exchanging the filters at staggered intervals. Preferably, the filter change is carried out depending on the carbon dioxide content of the room air leaving the filter. Part of the filter is exchanged in an unexhausted state after beginning operations and is replaced at the end of the overall working life up to complete exhaustion. The method makes possible simple control of the moisture load of the oxygen-releasing substance and thus the oxygen release, complete use of the total filter capacity during the entire working life and utilisation of each filter up to its exhaustion without losses in regeneration quality.

Title: Postal parcel conveyor system - has sections of angled roller conveyors travelling at increasing speed between belt conveyors
Inventor: CHARBONNIER PHILIPPE
IPC: B65G47/71
Filed: 1977-03-16
Abstract: The conveyor is made up of a number of belt conveyors in parallel which feed onto sections of roller conveyors. The parcels are then conveyed onto a further belt conveyor. Parallel double sets of roller conveyors cause two parallel lines to converge into one, until a single line belt conveyor carries the parcels over a number of bins for sorting. The roller conveyors are driven in series by Vee-belts along the outer edges of the rollers and at increasing speed, so that the last roller is faster than the first. Similarly the belt conveyor sections travel faster towards the outlet of the system.
Patent FR-2385096-A1 (FR)
Title: Gas flow composition analysis probe - use e.g. for IC engine exhaust gas testing
IPC: G01N27/12
Filed: 1977-03-22
Abstract: The probe measures the partial pressure of a particular component and it uses an element of which the electrical resistance varies as a function of the partial pressure of the component to be measured. Compensation for resistance variations due to temp. differences in the gas flow is made by comparison with the resistance of a second element subjected to the same temp. differences, which has identical resistance changes as a function of temp. but which is insensitive to changes in the partial pressure of the gas to be measured. The probe is partic useful for measuring oxygen content in a gas mixture, with numerous applications in industry. They can be used for testing the exhaust gases from internal combustion engines, thus making it possible to achieve optimum performance with minimum pollution.

Title: Machine to cut blocks of frozen meat into small tablets - uses horizontal rotary drum fitted with longitudinal and transverse meat cutters
IPC: B26D3/22
Filed: 1977-04-04
Abstract: The cutters comprise at least two slitting knives extending radially outward from the drum exterior and designed to cut longitudinal slits into the edge of a block pushed against the drum circumference. Behind the knives, in the direction of rotation, the drum surface forms an incurving slide which supports the pre-slit edge of the meat as far as a slot extending across the drum circumference. The far edge of the slot is fitted with a transverse blade which chops off pre-slit strips to cube or tablet size and drops them into the slot. Blocks of meat of size e.g. 400 x 600 x 150 mm. at 0 degrees to -20 degrees C can be chopped into tablets of e.g. 80 x 80 x 150 mm. Single machine cuts both longitudinal and transversely and is adjustable to a wide range of tablet sizes which are then produced to close dimensional limits. Simple to operate and maintain and extremely robust.
