Title: Improvements in or relating to the manufacture of artificial sausage casings
Inventor: FOX BERNARD VICTOR
IPC: A22C13/00
Filed: 1954-12-15
Abstract: Alginate sausage casings in the gel condition are subjected to a drying treatment to reduce their water-content to a value less than 50 per cent by weight of the dried casings, then rehumidified so that they become saturated with water and are finally inflated by fluid pressure so as to stretch them transversely.  Drying may be effected by passing the casings over heated rollers or by inflating the casings and passing them through a tubular drying oven. Rehumidification may be effected by treatment with water or steam. The stretching may be effected with air, nitrogen or carbon dioxide under pressure or by a liquid, e.g. water or an aqueous solution of calcium chloride or of ethyl alcohol, under hydrostatic pressure.  In the latter case the liquid is introduced into a portion of the casing, the casing then being passed down an inclined shoot and through a pair of driven nip-rollers which prevent passage of the liquid, the amount of inflation being controlled by the inclination of the shoot. The process is applicable to casings of water-insoluble alginates, e.g. calcium alginate, with or without a proportion of alginic acid, and the casings are, prior to drying, preferably washed, to remove soluble inpurities and treated with an aqueous solution of a softening agent, e.g. glycerine.  In an example, aqueous sodium alginate is extruded through an annular orifice into an aqueous coagulating bath containing calcium chloride and hydrochloric acid.  The so-formed tubular casing is then treated in an aqueous calcium chloride bath to effect conversion into calcium alginate, then washed, dried on rollers heated to 70 DEG  C. to reduce its water-content to 5 per cent by weight, rehumidified in water and finally inflated with water under pressure. Specification 784,640 is referred to.

Heading B1X A process for treating liquids for analysis wherein a stream of liquid is pumped by a flexible tube pump from a source of supply to an analysis apparatus in a conduit and a gas is introduced into said conduit to segmentize said stream is characterized in that said gas is introduced upstream of the pump. As illustrated in Fig. 1, samples from device 12 of the type claimed in Specification 834,635 are passed through line 18 into pump 10 after air from pump line 26 has been injected thereinto by means of T-junction 22. The sample is mixed with a conditioning liquid from line 30 and the mixture passed through a mixing coil to dialyser 44. A further processing liquid and air from lines 32, 34 respectively are passed through the other side of the dialyser and the dialisate is mixed with a final liquid from tube 36 before passing to the colorimeter 60 via mixing and heating coils. In Fig. 3, a system for determining the total sugar content of a liquid is illustrated. The solution enters apparatus 70 (shown more fully in Fig. 4) through line 72 and inlet 84, some of the solution overflows from a funnel-shaped port 90 and is vented at 110, an aperture 82 being provided to maintain atmospheric pressure, while a portion of the liquid is withdrawn by a line dipping into the liquid in port 90. The latter portion is segmented in accordance with the invention by air from line 76 and inlet 106 and passes through the pump 16. It is diluted with water from line 134 mixed in coil 136, a portion is vented by means of a T-junction 112, an acid (e.g. 0.25 NHCl) is added through tube 140 to invert non-reducing sugars and reaction effected by mixing (coil 142) and heating (bath 146). The mixture passes through dialyser 44 in which dialysed sugars are separated from contaminants and pass into a segmentized stream of aq. K 3 Fe(CN) 6  on the opposite side of the diaphragm. An alkali (e.g. 0.3 N NaOH) is added via line 160, mixed with the stream in coil 164 to neutralize the acid, and the mixture is then heated in coil 166 to produce a colour change as ferrocyanide is formed. The stream is passed to colorimeter 60. Specifications 774,711 and 855,555 also are referred to.

The softening temperature is the lowest temperature at which dislocations are still produced by thermal stresses inside the material.  When a single crystal 1 (Fig. 1) is produced by passing a molten zone 4 down a rod of material, the zone 4 is produced by heating a graphite ring 2 by a high-frequency coil 3, and loss of heat from the single crystal part of the rod 1 is compensated by radiation from the flat surface 5 of the ring.  The ring preferably has an outside diameter between 2 and 3 times the diameter of the rod, and temperature between 1.2 and 1.5 times the melting temperature of the rod.  When rod 1 is grown from a melt 11 (Fig. 2) in a crucible 10, the ring 2 is floated on the melt, or the rod is grown from a crucible 15 (Fig. 3) floating in the melt 11 and connected thereto through an opening 17, heat being radiated by a flat rim 18 of the crucible 15.  In other embodiments (Figs. 4, 5 and 6) the rings have conical radiating surfaces at an angle a  of more than 30 degrees, preferably 40 to 50 degrees, to the axis of the rod.  The material may be a semi-conductor, such as silicon or germanium.  Specification 827,466 is referred to.
