Title: Decontaminating superficial layer of food prod. esp. meat for cutting - by steaming then chilling, both at atmos. pressure
Inventor: BEFFY ROGER
IPC: A23B4/005
Filed: 1980-12-30
Abstract: The prod. is subjected to two stages of treatment. In the first stage, steam is condensed on the surface of the prod. in a chamber at atmos. pressure. The prod. pref. enters the chamber at a temp. below 10 deg.C., more partic. about 5 deg C. The first stage pref. has a duration of above one minute after which the surface temp. of the prod. is 90-100 deg. C. In the second stage, a superficial layer of the prod. is rapidly chilled, pref. by spraying with a mixt. of dry ice in air. The duration of the second stage is pref. between 10 and 15 seconds. On removal from the second stage, the temp. of the prod. as a whole is pref. slightly lower than when the prod. started its first stage of treatment. The prod. can be subjected to an intermediate stage of drying between steaming and chilling. Drying is pref. by means of a flow of air which has been passed through a bacteriological filter. The decontamination process is partic. adapted to treating quarters of meat prior to cutting. The installation is simple and inexpensive and is carried out at atmospheric pressure. The process can be continuous by conveying prod. through the two stages in turn. Alternatively, the two treatment stages can be carried out in succession in single cabinet.

Patent FR-2500348-A1 (FR)
Title: Temporary backing bar for fusion welded joints - in pipework and boiler-making
IPC: B23K9/035
Filed: 1981-02-26
Abstract: A moving belt forms a temporary backing bar for the weld pool when the base sealing run is put down in a welded joint. It passes round support rollers which rension it and press it against the underside of the joint. It is applied without sliding, so that there is no relative motion at the point of contact. The belt can be made from jointed links, either refractory or consumable, or strip metal. There is a groove in the centre of the belt directly behind the joint, and heat is removed by water cooling. The assembly is carried by a moving trolley, and positioned below the joint by a system of lights. This invention is intended for pipe work and boiler making. The base run is critical either manually or by machine and requires very skilled personnel. A fixed backing bar gives good results, but is difficult to insert and remove. This invention by avoiding relative motion between belt and joint, gives equivalent results.

Title: Tool for testing contact pressures of multi-socket electrical coupling - for simultaneous testing of all individual sockets
Inventor: BRICAUD HERVE
IPC: G01L5/00
Filed: 1981-11-10
Abstract: A device for checking the clamping pressure of an electrical socket junction comprises a tool from which a bent spring strip is supported as a cantilever so that the free end overlaps a second bar itself cantilevered from between stress or strain gauges so that deflection of the second bar indicates the stress level applied by the socket fitting in accepting the bent section of the first bar. Several such bent strip/strain transducer systems can be mounted in parallel, close together (e.g. at a pitch of 2.54 mm.) to allow all the sockets of a flat multi-socket cable junction to be checked simultaneously and independently - saving much time in that aspect of quality control during socket mfr. The transducer is pref. a piezo electric leaf based on monoammonium phosphate crystals, or a ceramic crystal based on Pb Zr titanate or Ba titanate aligned at 45 degrees to the Z axis and sensitive to displacements of about 10 microns, for checking probe compression of the order of tenths to hundredths of a mm. Typically the piezoelectric leaves may be 12.7 x 1.5 x 0.7 mm. section: the dimension and characteristics, e.g. stiffness of the bent probe are not specified, except for the probe bend being through 180 degrees and the free end being stepped outwards to accommodate the tip of the transducer leaf.
