Title: Indicator of unacceptable temp. rise of frozen food etc. - reveals irreversible colour change as substance melts and soaks indicator pad
IPC: G01K11/06
Filed: 1980-07-04
Abstract: A method of checking and an indicator for revealing, whether the temp. of the prod. partic. a food prod, has at any time exceeded a predetermined value. The indicator employs the change of state of a substance from solid to liq. to produce an irreversible mark on a recording pad. Pref. the substance is contained in a plastic sachet of which part of the wall is ruptured by expansion of the substance as it freezes from liq. to solid state. If the predetermine temp. is exceeded, the substance melts and soaks into an absorbent recording pad. Pref. both sacket and pad are contained in a transparent, plastic envelope. The substance in the sachet is pref. a soln. of sodium chloride or of calcium chloride. The substance pref. has a freezing point between 0 and -40 deg.C. The absorbent recording pad is pref. white in colour. The fault remains obvious even if the temp. is restored subsequently to an acceptably low level. The indicator is inexpensive to produce and easy to use.

Title: Gas filter which can be regenerated - has fibrous filter packing, which is stretched and vibrated to remove solid particles (AT 15.1.82)
Inventor: NEMTSOV NIKOLAI STEPANOVICH
IPC: B01D46/30
Filed: 1980-08-28
Abstract: The filter consists of a vertical ring cylinder contg. a vertical stack of funnel-shaped partitions dividing the cylinder into several zones. A slotted axial tube feeds a gas to be purified into the zones. Each zone contains a pair of funnel-shaped grids supporting a fibrous filter packing. In the axial tube is a vertical rod with arms passing through the inclined gas inlet slots; and the arms support the lower grid in each pair of grids. When the filter requires regeneration, the rod is lowered so the filter fibres are stretched between each pair of grids. The rod is pref. fitted with a vibrator, so the solid particles trapped by the filter fall off into a bottom hopper. High efficiency purificn. of large vols. of gas, and simple regeneration is achieved.

Title: Mechanically tuned stop-band filter - has adjustable metal rods providing tuning in gigahertz range by penetration into coaxial guide
Inventor: DELABALLE JACQUES
IPC: H01P1/208
Filed: 1980-11-07
Abstract: The mechanically tuned stop-band filter operates over the range 2 to 2.3 GHz and has a section of coaxial waveguide (1) and an integral number n (n being a positive integer) dielectric resonators (4,6). These are situated between the internal (3) and external (12) conductors of the waveguide section. A like number of metal rods pass through the external conductor wall, and are associated with respective resonators. The metal rods allow control of the central frequency of the stop-band of the filter by controlling their depth of penetration into the guide. P of the n resonators comprise hollow tubes so that the rods which pass into them may be adjusted to vary the stop band frequency. The waveguide is rectangular in section with the resonator mounted inside one large side, and tuning rods passing through the opposite long side.
