Title: Heat exchangers
IPC: C04B33/13
Filed: 1970-12-11
Abstract: 1367640 Heat exchangers IMPERIAL CHEMICAL INDUSTRIES Ltd 25 Nov 1971 [11 Dec 1970] 59030/70 Heading F4S A block heat exchanger is constructed from a composite heat transfer material comprising aluminium phosphate and a refractory filler. The filler may be fibrous material in the form of a woven cloth or mat or be particulate material of high conductivity. Examples of suitable fibres are: alumina and zirconia fibre, silica glass fibre, alumina-silicate fibre and aluminium phosphate fibre. Examples of particulate fillers are: refractory metal carbides and nitrides such as titanium carbide, silica flour, fused amorphous silica and fused silica grog. The aluminium phosphate serves as a binder. Preferably the aluminium phosphate is derived from a complex phosphate of aluminium containing at least one chemically bound molecule of water or a hydroxy compound R-OH wherein R is an organic group, and an anionic group of a strong inorganic acid or a carboxylic acid. Examples of complex phosphates are phosphates containing ethyl alcohol and having the empirical formula ALPCLH 25 C 8 O 8  or ALPCLH 11 O 9 . The block heat exchanger shown is constructed from sheets of aluminium phosphate containing particulate filler, the block being built up from suitably grooved rectangular sheets, the grooves 30, 31 of adjacent sheets co-operating to form two series of circular passages 22, 23 at right angles to one another for the respective heat exchange fluids. Headers 36 are provided. A modified form of block heat exchanger is disclosed (see Figs. 1-3). In an alternative embodiment (Figs. 4 and 5) alternately arranged flat and corrugated sheets of silica glass cloth impregnated with aluminium phosphate define a plate heat exchanger stack which is suitably heated and cured at 120‹ C.

Such rotation of each cog wheel 6 is effected by engagement with the wheel of the associated plunger rod 10 followed by subsequent movement of the rod 10 tangentially to the wheel this movement deriving from axial movement of a carrier 7 upon which the solenoids and plunger rods are mounted. This axial movement may lie in either axial direction depending upon the rotation of a motor driven crank 13 and crank drive 8, Fig. 3. The pressures exerted by the screws 3 on the lower edge of the blade 2 are limited by associating overload clutches with each cog wheel 6. The ductor blade adjustment by the screws 3 may be automatically operated through electrical circuitry.

Title: Circuit arrangement for adjusting a variable-ratio transformer by means of an electric motor
IPC: G05F1/24
Filed: 1978-10-30
Abstract: A system for regulating the output of a variable ratio transformer uses a reversible servo-motor 11 in which the actual voltage Ui is compared with the required voltage Us in a comparator 1 to produce an error signal which is applied to a two-way relay 13 to control the direction of rotation of the motor. The output 3 of the comparator is delayed by ti in a delay circuit 14 and thence passed to a flip-flop 16, the output of which controls the relay 13. Transitory changes in Ui e.g. due to interference thus fail to trigger the relay. The output 4 of the comparator 1 is also delayed by ti in delay circuit 14, but is further delayed by an additional amount t2 in a delay circuit 15. The output of this latter delay circuit is passed to an electronic switch 12 to prevent current being applied to the motor 11 before the contacts of relay 13 have had a chance to switch over. <IMAGE>
