Title: Improvements in steaks and method of producing same
IPC: A23B4/06
Filed: 1930-05-19
Abstract: Steaks are formed from pieces of fish or other meat which are assembled in a substantially cylindrical mass, e.g. in a mould or semi-cylindrical trough, the pieces being preferably in fillets with the muscle fibres parallel to one another, and the mass is wrapped as it issues from the mould by a tape wound helically with the convolutions overlapping, the wrapped mass being cut transversely into slices or steaks either before or after freezing.  The tape may be of paper, parchment paper, regenerated cellulose or fabric, and in order to compensate for subsequent stretching and loosening of the tape, it may be wetted at some stage of the wrapping.  The adherence of the fish-pieces to one another may be improved by treatment with a mild alkaline brine, or by permitting them to dry slightly before wrapping.

[Also in Group XXXV] To measure the specific resistance of sugar solution during its treatment in a crystallizing boiler a, with a view to ensuring stabilization of concentration (see Group XXXV), current from a transformer 8 passes between electrodes 1, 2, 3, at the same level, and the boiler wall 10. In order to obtain a measurement more accurately dependent on the mean specific resistance as boiling progresses, relays 17 and 18, which become energized in turn as the level in the boiler reaches auxiliary electrodes 6 and 7, change-over contacts 13 and 14 to substitute first a higher electrode 4 for electrode 3 and then a still higher electrode 5 for electrode 2. In a modification, pre-set resistances connected between electrodes 4 and 5 and the boiler wall vary the specific resistance of the boiling mass as a function of its height in the boiler. The construction of an auxiliary electrode provided with a bevelled disc of insulating material to increase the length of the leakage path between the electrode and the boiler wall when the electrode is not immersed, is described.

A magnetic spectrometer suitable for introduction at an intermediate stage of a rectilinear particle path-e.g. in an electron microscopehas aligned entrance and exit apertures, and a non-uniform transverse magnetic field, such that charged particles of a desired mass or energy just perform one cycle of a trochoidal path in passing through the field, and therefore emerge from the spectrometer moving again along the axis. Polepieces 12 and 13 are mounted in an evacuated cylindrical container 1, half shown in Fig. 2, particles to be analysed entering through a central aperture in the upper closing diaphragm of the container (Fig. 1, not shown) and passing generally down the axis of the container, first through the non-uniform field between the inclined pole faces 31 and 32, and then through a tube 8, which acts as a magnetic screen and extends to a central, exit aperture in the bottom wall of the container, this aperture having an associated slit which is adjustable both in width and position. The magnetic field intensity and distribution are adjustable by adjustment of the magnet energizing current and-by rotation of the polepieces on their core members 14 and 15-of the inclination between the pole faces. If the planes of the latter intersect at a distance x = f from the axis, the flux density B in the direction between the pole faces is given by B = K/f-x, where K is a parameter dependent upon the magnet exciting current. Charged particles entering the spectrometer pursue a trochoidal path in this field, variation of the exciting current and pole face inclination permitting adjustment to a condition in which particles of a particular desired energy (eV, Fig. 5, not shown) just complete one cycle of the path in passing through the field, and therefore emerge from it travelling along the axis, and pass out through the spectrometer exit slit.
