Abstract: 1,193,623. Thawing frozen foods. P. EISLER. 17 April, 1967 [11 Nov., 1966; 12 Dec., 1966], Nos. 62008/69 and 55452/66. Divided out of 1,193,622. Heading A2D. [Also in Divisions A4, B8 and H5] A spacer 307, 351 of good thermal conductivity between an electric heating film 303, 354 and a substance 353 to be heated, e.g. a slab or package of food, which may be frozen initially, holds the temperature at which heat is dissipated into the substance at a temperature lower than the surface temperature of the film. A pervious or porous spacer 307, which is edible or a loosely woven, knitted or tangled material of cord, wire or nylon, holds a body of liquid which is heated by a heating film 303 and in turn heats the substance (not shown) by delivering the latent heat of its vapour thereto. Where the liquid is water, the temperature of the substance will not rise above 100‹C. A perforated liner 308 receives the substance to be heated, and the spacer may be integral with the bottom of the liner, Figs. 4, 5 (not shown) which is folded into ribs 309 located between the apertures or perforations. In a further embodiment, Fig. 6, the spacer is the thermostatically controlled metal plate 351 of Specification 1,193,622. Specification 1,193,621 is also referred to. The heating film is as described in Specifications 900,517, 992,571, 992,573, 992,574, 905,867, 912,980, 1,020,311, 1,020,312, 1,020,316 and 1,020,317. Rapid heating of frozen food is accelerated by the tray 301 being vibrated and/or by the heating film being supplied with pulsed current. The spacer 307 and liquid are edible when food is being heated, e.g. the spacer being a slab of ice or edible jelly, or a porous biscuit or wafer, or a reticulated jelly structure, with the spacer filled with water, preferably frozen when assembled. A slab of frozen food may be shaped like an inverted pyramid and a heavily crimped heating film collects the liquid in its crimps, the spacing being effected by the shaping of the slab

Abstract: 1388318 All-pass networks WESTERN ELECTRIC CO Inc 13 Dec 1972 [15 Dec 1971] 57414/72 Heading H3U All pass transmission networks comprise a pair 10, 11 of hybrid quadrature couplers whose branches ; 1, 2; 3, 4; 1<SP>1</SP>, 2<SP>1</SP>; 3<SP>1</SP>, 4<SP>1</SP>; are conjugate within each pair, the transfer function 1 # 3; 2 # 4; 3<SP>1</SP> # 1<SP>1</SP>; 4<SP>1</SP> # 2<SP>1</SP> being t, that of 1 # 4; 2 # 3; 3<SP>1</SP> # 2<SP>1</SP>; 4<SP>1</SP> # 1<SP>1</SP> being ik i<SP>2</SP> = - 1, an input signal of unit value at branch 1 thus producing the quadrature pair t, ik at branches 3, 4. The transfer functions although having the frequency dependences displayed in Fig. 2 (not shown), satisfy the relation By connecting the couplers 10, 11 in cascade, with a 180 degrees shifting 1 : 1 transformer in line 12, a signal of values {1, 0} on brances 1, 2 leads to the pair {-1, 0} on branches 1<SP>1</SP>, 2<SP>1</SP> with a residual phase shift 0 degrees. The network of Fig. 1 has a larger pass band than that of transformer 14, which needs only to have the low frequency pass band of Fig. 2 (not shown), where t is substantial. By putting a 1 : 1 transformer (14<SP>1</SP>) Fig. 3 (not shown) having a high frequency pass band in the line 13, i.e. for frequencies whereat k is substantial, the same input pair {1, 0} leads to the pair {1, 0} at the output 1<SP>1</SP>, 21, with a residual phase shift # degrees. By placing 1 : N transformers in both lines (62, 63) Fig. 6 (not shown) connecting the couplers, one connected in a phase inverting sense, coupler (61) being adapted to correspondingly higher impedance levels, by a factor N<SP>2</SP>, than coupler (60), the network has the character of a transformer, whose bandwidth is greater than that of either transformers (64, 65), the former being designed for low pass, the latter for high pass. In a bootstrap arrangement to further increase band pass the transformer 14 is itself replaced by the network of Fig. 1, the network of Fig. 3 (not shown) being placed in line 13, see Fig. 5. This process can be iterated for further bandwidth increase, or combined with phase equalization techiques. By connecting the networks of Fig. 1 (Fig. 3) in parallel, Fig. 4 (not shown) the signals at the output branches (1<SP>1</SP>,1<SP>1</SP>), for a sigual applied to both input branches (1, 1) are precisely 180 degrees out of phase, both sharing the same residual phase shift # degrees. Each coupler may be a complex cascade of components, leading to the sharpened transfer functions of Fig. 7 (not shown), enabling the band pass of the transformers to be further reduced with respect to the network band pass.

[Also in Division B8] Mosaic character thermo-printers.-A thermoprinting device comprises forming each character by the selective heating of bar elements 1-8 in the form of resistors by current supplied by conductors 11 consisting of film deposits on the surface of an electrically insulating base 10. There may be a mosaic of resistors in each character space in a line to be printed, or, as shown in Fig. 10, there may be a mosaic in each position, on a page or a plurality of lines. The characters in each position are built up together in that all the, say, middle elements 1 required are energized together, then all the separate top elements 2 of the mosaic are energized, then all the elements 3 &C until all characters are completely formed. Construction of print heads.-The. elements 1-8. are applied by using the methods of making printed circuits and may consist of chromium in a thickness corresponding to 100 #/square and the supply conductors 11 being of gold in a thickness corresponding to 0-5 #/ square with a width of 0À1-0À2 mm. The printing is applied to an insulating base 10 and may be protected by a wear resistant film, e.g. quartz. As shown in Fig. 11 the conductors 11 are extended by conductors 27 between insulating layers 28 to provide a spread for the attachment of wiring. Web feeding arrangements.-In the embodiment, Fig. 10, where a number of whole lines are printed simultaneously the web is fed by continuously rotating feed rollers 32, 33, the speed of which is governed by a loop indicator 34. A cylinder 29 feeds the web to and from the printing elements arranged arcuately around the cylinder in conjunction with the impression mechanism 30, 31. Pneumatically actuated impression and paper feeding mechanism.-After. a length of web 22 is fed to the printing position the impression mechanism 30, 31 is supplied with air under pressure and the web is pressed against the thermo-printing elements. After printing the air source is switched to a suction action whereupon the web 22 is drawn against the rotating cylinder 29 and feed forward the requisite number of lines. Reversed or positive type.-the web 22 may be fed behind a viewing glass (24) facing the position of an operator and the printing elements operate from behind the web. The thermosensitive coating on the paper being on the rear side causes a change of colour on the front side. The characters are thus immediately visible.
