Title: Quenching moving metal strip with water mist - which is blown transversely across both the upper and lower surfaces of the strip
Inventor: LHENRY BERNARD
IPC: C21D1/62
Filed: 1979-10-31
Abstract: The strip travels in its longitudinal direction (F) between a lower (53)- and an upper (54)- quenching zone. Air is blown transversely across the strip in both zones (53,54); and the air inlet surrounds lower and upper nozzles (71,72) blowing water into zones (53,54), so an aerosol contg. water droplets travels across the strip. Pipes fitted with water outlet nozzles are also located transversely above and below the strip, so more water can be fed into zones (53,54). The amt. of water used produces a wt. ratio of water to air above 9:1 at the outlet of zones (53,54); and the water droplets are pref. 350-450 microns dia. The pref. quenching machine uses zones (53,54) which increase in depth towards their outlet.

Title: Temp. measurement unit for interior of HF coaxial cable - uses small bore hole in outer conductor as viewing window for ir radiation to external sensor
IPC: H01B11/18
Filed: 1979-12-07
Abstract: The arrangement comprises a high frequency coaxial cable (10) with an inner conductor (12), the latter being viewed through a bore-hole (14) in the outer conductor wall, the hole being typically from 2 to 3mm in diameter. An infra-red sensor (16) is situated immediately opposite the hole, and is connected with an electronic converter (18) and a display unit (20). In a more refined system, a rotating aperture shutter is used to produce an intermittent signal, which produces an a.c. signal which may be amplified by a function amplifier. The electronic circuit also caters for a signal from a comparison unit which compensates for temp. variations. The aperture control units permit control of the solid angle (OMEGA-omega) so that comparison signals of similar electrical amplitude may be obtained.

Patent FR-2466961-A1 (FR)
Inventor: FROHLICH ALFONS
IPC: A44B19/40
Filed: 1980-10-09
Abstract: The stringer tapes are made up of main warp threads and mutually adjacent double wefts (4, 5) of a continuous main weft thread (6). The rows of closure members are designed in each case in the form of a plastic monofilament double weft, with lower and upper limbs (8, 9) of the closure members lying essentially superimposed in a projection towards the zip fastener plane. They are covered by binder warp threads (12) offset in relation to one another in the longitudinal direction of the zip fastener with respect to the weft insertion, and are thus connected to the stringer tape. Moreover, double wefts (5) of the main weft threads (6) in the area between the closure members (8, 9) and in addition double wefts (4) of the main weft threads (6) under the closure members (8, 9) are arranged in individual main warp thread pockets of a stringer tape area lying under the closure members. The double wefts (5) of the main weft thread are pulled up in the area between the closure members (8, 9) by means of at least one of the binder warp threads (12) over the plane of the stringer tapes into the area between the closure members, advantageously as far as or above the level of the upper limb (9) of the closure members. In this way the resistance of the zip fastener to bending is improved.

Title: Pressure steam peeling machine for fruit and vegetables - tumbles prod. in rotary basket which diffuses steam uniformly to reduce peeling time
Inventor: BELLATI VITTORIO
IPC: A23N7/00
Filed: 1981-01-06
Abstract: The machine comprises a pressure vessel in which the prod. is contacted with live steam under pressure, and which has a drainage system for condensate etc. In the vessel, the prod. is contained and treated in a power-rotated, horizontal cylindrical basket, a clear space being retained all round between basket and vessel wall. The basket perforations follow a regular pattern so that steam, injected into the clear space, is distributed uniformly into all parts of the basket. The interior of the basket has a number of projecting paddles which lift and tumble the prod. as the basket rotates. Pref. the cylindrical basket is coaxially disposed within a horizontal, cylindrical vessel. Both basket and vessel may be rotated together or the basket may be rotated independently within a stationary vessel. The basket and vessel can be mounted on a horizontal pivot at right angles to the longitudinal axis of the basket. The basket can then be emptied by tilting. Injected steam is distributed uniformly through the tumbled prod. All the prod. becomes softened to about the same depth in the same time. This results in shorter peeling time and higher yield of prod. Previously, some prod. became over-steamed to the point of disintegration before other prod. had softened to peeling depth.

Abstract: The telecommunications cable uses cylindrical section insulated former (1) to carry symmetric pairs of electric conductors and optical fibres in grooves (5,6) along the surface of the former. A reinforcing wire (9) runs down the centre of the former to provide structural strength to the cable. The grooves carrying the conductors are of a concave helical section or may alternatively be of a curvilinear 'V' section. Smaller grooves (6) are provided for small section cable (7). Conductors are laid in the grooves in symmetric pairs. The groove pairs may be used for optical fibres, for service wires, for locating wires, or for micro-coaxial cable.

Title: Detonator for anti-tank mines - has own power supply and is activated electronically when geomagnetic field is displaced by vehicle passing neighbourhood
Inventor: GERUM ERICH
IPC: F42C11/00
Filed: 1981-03-04
Abstract: The sensing unit (1) consists of two pairs of steel bolts (3,3a,4,4a) fixed side by side on a carrier plate (2). Each bolt of the pair, tapers conically towards the centre of the carrier plate (2) where a field plate (7,7a) separates the truncations of the bolts (3,3a,4,4a) and is encapsulated in a plastic material contained with the help of filter discs (9). A magnet (5) is positioned between two of the coaxially to one another bolt sections (3,4). The two field plates (7,7a) form part of the electronic circuit containing a switching transistor in the digital control section of the analogue-digital circuitry. The circuitry used for sensing the passage of a tracked vehicle or track, because of the introduction of a particular impulse control, attains a considerable reduction in field plate current together with a relatively high sensitivity.
