Title: Improvements in or relating to freeze drying
Inventor: PORTA PAOLO DELLA
IPC: F26B5/06
Filed: 1962-12-19
Abstract: In apparatus for freeze-drying foodstuffs in liquid or slurry form the material is frozen as a slab on to and around a single, embedded heating element and thereafter placed within a vacuum chamber, heat being supplied to the material by conduction from the element.  The element comprises a grid, the flange portions of which rest on electrodes when the grids are positioned on movable carriages in the vacuum chamber and additional fixed radiant heater plates connected to a steam header may be mounted above and below the electrodes.  The embedded element may be an electrical resistance grid in the form of conducting wires or glass fibre cloth impregnated with graphite, an electrically heated plate, either perforated or unperforated, provided with indentations, protrusions or a key to lock into the material when frozen. Alternatively, the embedded element comprises a plane, perforated, metal sheet having a serpentine duct for the passage of a refrigerant and thereafter of a heating fluid.

In a vehicle gear-box giving both synchronized and unsynchronized ratio shifts engagement of an unsynchronized ratio is facilitated by interconnecting the appropriate shift-rod with the shift-rod for one of the synchronized ratios, preferably the highest, so that the initial movement of the rod automatically moves the synchronized rod through a limited distance sufficient to operate the synchronizer but not engage the ratio, completion of shift returning the displaced rod to its neutral setting. In the arrangement shown for synchronized four-speed forward and unsynchronized single reverse ratios, the forward drive rods 16, 17 and reverse drive rod 18 are interconnected by the normal detents 28, 34, 35 and transverse drift pins 21, 22, and in addition rods 17, 18 are connected by a weak detent 43 and rod 17 is formed with a short longitudinal recess 40 engageable by drift pin 22. In operation the initial movement of rod 18 moves rod 17 to the left until prevented by drift pin 22, thereby engaging the fourth speed synchronizer, the final movement of rod 18 carrying detent 43 into a second recess 46 in rod 17 and having an inclined surface 47 serving to return rod 18 to its neutral position.

Apparatus for unloading a ship comprising hatches 2a, 2b for holds divided by bulkheads 1, comprises a main conveyer 12 running longitudinally of the ship and a tripper device 13 for feeding material to or from transverse conveyer means mounted in some of the hatch cover panels 4a. The tripper device 13 comprises a driven tripper 14b, Fig. 9, over guide rollers 25, 26 of which the main conveyer belt 12 runs so that material can fall back on to it through guide plates 27, 28 or when the tripper is attached to a self-travelling tripper 14a, the material drops through the guide plate 27 on to a conveyer 18 for discharge on to a transverse conveyer 19. The material handling hatch cover panels 4a have an opening 35 with guide plates 36 and upper hinged guide plates 38 which can be closed as in Fig. 11 or opened and the guides closed at their ends by canvas sheets to form a hopper 11 which feeds on to a traversing conveyer 10. The holds are closed by a cover 39, Fig. 10. The conveyer 10 can be driven in either direction, Fig. 10, and moved to positions 10a, 10b to fill a hold at either side A, B. Alternatively, the conveyer 19 can feed directly to position B in the hold or to position A by discharging through a shoot 20 on to the conveyer 10. The hatch panels 4a are movable on wheels 8 to load or unload a hold on either side of a bulkhead I -and the tripper device 13 when parts 14a and 14b are coupled together can be positioned correctly relative to the panel 4a by the self,travelling tripper 14a running on rails 17. Thus to load a hold material conveyed on the conveyer 12 is via conveyers 18, 19 of the tripper device loaded into the hold directly at point B or via the conveyer 10 to the point A. To unload material is lifted as by a grab operated by cranes positioned between holds into the hatch panel hopper 11 from which it falls on to the conveyer 10 for discharge to the main conveyer 12, when the conveyer 10 is extended through a door 34 in the panel 4a.
