Abstract: 1295150 Automatic circuit breakers FELTEN & GULLEAUME SCHALTANLAGEN GmbH 17 Dec 1970 [2 Jan 1970] 60052/70 Heading H1N An automatic circuit breaker has a tripping mechanism comprising a pivotable armature 7 mounted across two pole pieces 2, 3, a trip coil 4 wound on pole piece 2 and a rotatable, diametrically magnetized permanent magnet 5 located in an aperture in pole piece 3. The armature 7 is normally held in its attracted position by the permanent magnet 5 but, if a fault current of sufficient magnitude flows throgh coil 4, alternate half-cycles oppose this magnetizer and the armature is pulled off by spring 12 and consequently actuates the trip bar 15. The armature is mounted by being attached, at its right hand end to a blade spring 10, the other end of which is secured to the upper face of the coil 4. Furthermore, the armature is bent upwards slightly about its line of pivoted contact with the pole-piece 3 so that the spring 12 exerts an increasing moment as the armature moves in a pull-off direction.

The block 17 has a lower pear-shaped portion 18 which enters the empty can 10 so that as meat is forced into the ean, the latter is pushed downwardly until full a valve 102 allowing relief of fluid in the platform cylinder 49. When full a lug 99 on a platform guide shaft 46 triggers a valve 100 which redirects the air flow to the upper end of the platform cylinder 49 to cause the platform to be positively lowered to its initial position. During filling the can sides are supported by a backstop (66, Fig. 4) and a pair of cushioned jaws 61, 62 pivotally mounted on the block 17 and actuated by fluidic cylinders 67, 68. The block 17 contains a filler valve 22 comprising a slotted horizontal cylinder 23 which is appropriately rotated by a pivotable fluidic cylinder 33. To reduce meat adherence the block 17 may contain heating elements (37, Fig. 3) and have a smooth lower face that may be coated with P.T.F.E. The block 17 which may be of stainless steel has a detachable rear portion (20, Fig. 2) to permit access to the valve 22. The pressure vessel 13 may comprise a piston operated sausage stuffer. The fluidic circuit is fully described.

Abstract: 1307985 Electrophysical measurements SYBROOK ELECTRONICS Ltd 14 April 1970 [18 April 1969] 19889/69 Heading G1N [Also in Division H1] An inductive transducer has a hollow coil 2 Fig. 1c, and a number of flat core U-shaped members 4 spaced around the core each with one leg inside the core and separated by (sector shaped or rod-like) spaces. The winding wire may have ceramic or gloss insulation and the core flecs may be of nickel iron alloy. Two such transducers may be cemented inside a non- magnetic container 8 of austenitic steel, one, 7 being usable for securing changes in inductive coupling (e. g. for measuring displacement of a turbine shaft) whilst the other, 8, provides a degree of compensation for temperature changes. The coil formula may be of alumina (sintered) or silicon nitride. The forward end of the casing may be closed by a heat shield 10 of austenitic steel. The working transducer 7 may be separated from 8 by a partition 12 integral with the casing, a reference plate 13 of the same material as the target to be monitored a ceramic disc 14 which provides a non-magnetic gap of about the mean displacement to be measured and a metal disc 15 similar to the heat shield 10 to make compensation of change of permeability of 10 with temperature changes. Terminal members 17 carried by a ceramic ring 16 may be formed by legs of spiral springs under compression 17, Fig. 3 (not shown) to allow for expansion and contraction. Vibratory filling of the spaces in casing 8 with alumina powder may be effected or potting material may be used.
