Patent GB-795806-A (GB)
Abstract: 795,806. Moving coil instruments. ELLIOTT BROS. (LONDON), Ltd. Aug. 12, 1955 [Aug. 12, 1954], No. 23479/54. Class 37. An electric measuring or indicating instrument has a magnetic assembly having a plurality of air gaps traversed by the magnetic flux and a moving coil located between the poles of each of the air gaps. Fig. 1 shows a magnet assembly for moving coil-type instruments comprising a bar-type permanent magnet 1 preferably made from an isotropic material and having a preferred magnetic axis indicated by the arrow. The flux path comprises polepieces 2, 3, 4 of high permeability material, in which two similar air gaps 5 of circular cross-section are formed in each of which is located a cylindrical core 6 of high permeability material. Each core 6 is embraced by a former 7 of non-magnetic material such as copper or aluminium on which is wound coil 8 having a pointer 9 attached. The two air gaps 5 are magnetically in series and substantially the same amount of flux traverses each, the arrangement provides in effect two moving coil instruments with a common magnet assembly. In an alternative arrangement, Fig. 2, the two air gaps 5 are arranged to be magnetically in parallel, the magnet 1 is of U-shape and the polepieces 2 and 4 are formed from one piece of high-permeability material. In a modification shown in Fig. 4, four permanent bar magnets 1 are provided, the four air gaps 5 each containing a core 6 of high permeability material and moving coil 8 carried on a former 7 with a pointer 9. Thus a single magnet assembly provides four moving-coil type instruments, the four air gaps are magnetically in series. In a further arrangement, Figs. 5 and 6, the magnet assembly has four gaps 5 each having a coil 8 located therein, the assembly comprises four similar permanent magnets 1 arranged with their magnet axis parallel and with the north pole of one magnet adjacent the south pole of two adjacent magnets. The magnet circuit is completed at the poles of the magnets 1 remote from those at which the air gaps are formed by a yoke 10, Fig. 6, of high permeability material which is common to all four magnets. In this arrangement the air gaps are effectively in series parallel. A non- uniform flux distribution may be provided as shown in Fig. 7 by different shape air gaps or core construction. Thus the gap 5a is of substantially elliptical cross-section and core 6a has a cross-section corresponding to the surface line between two parallel cords of a circle equally spaced from the parallel diameter. Each core carries former 7, coil 8 and pointer 9 as previously. By suitably shaping the air gaps 5 and the associated core 6 the flux distribution in the gaps may be made to follow a predetermined pattern so that the angular displacement of the moving coil for a given current therethrough is a predetermined function of the current.

Title: Control circuit for electric heater element
IPC: G05D23/24
Filed: 1981-01-20
Abstract: A control circuit for an electric heater element 12 e.g. in a fan heater includes a triac 13 in series with the element 12 and responsive to gate signals from a logic device 14 of a known type. The device 14 includes means for generating a ramp voltage having a frequency of between 1 and 0.2 Hz. The device 14 also includes means for comparing the ramp voltage with a further voltage at a terminal 8 of the device 14, this further voltage being dependent on the difference between a temperature sensed by a thermistor 15 and a desired temperature set by a variable resistor 18. The device 14 provides the gate signal to the triac 13 for a fraction of each ramp cycle, this fraction being dependent on the amount by which the sensed temperature is less than the desired temperature. The use of a higher ramp frequency than in the prior art is stated to avoid discomfort as a result of cold air being discharged from the heater during OFF intervals. <IMAGE>

Title: Absorbent acrylamide copolymers plant growing media
Inventor: BOSLEY JOHN ANTHONY
IPC: C05G3/80
Filed: 1982-08-05
Abstract: Superabsorbent gel compositions useful as plant growing media additives are prepared from a copolymer of acrylamide and acrylic acid salt in a molar ratio of 70:30 to 95:5, cross-linked such that less than 30% by weight of the dry polymer is water-soluble and the gel can absorb releasably at least 15 times its own weight of water. The gel composition is therefore tailored to the needs of an agricultural/horticultural context because it has long-term stability in natural soil, low solubility that would otherwise lead to poor soil properties, and good water absorbency. Preferred gel compositions in foam form are described.
