Abstract: 966,584. Plate-type evaporator and condenser apparatus. SEPARATOR A.B. July 4, 1961 [July 18, 1960], No. 24093/61. Heading B1B. Evaporation of liquid and/or condensation of vapour is carried out in an apparatus comprising two or more plate-type units, a liquid/ vapour separator being clamped between each pair of units. The apparatus may be operated on the multiple-effect principle, and is suitable for the evaporation of milk or for the distillation of water. Preheated milk is introduced through pipe 16 into channel 18 whence it passes up into alternate compartments between the plates of unit 2, and is partially evaporated by heat-exchange with steam which is introduced, through pipe 23, into the other compartments of the unit. A mixture of milk and vapour flows up into channel 17 and into separator 3 ; the separated milk either being recirculated into unit 2 or being passed via a reducing valve (not shown) into unit 4 via channel 20. In unit 4 the milk undergoes further evaporation, the vapour from separator 3 being used as the heating medium in the plates of the unit. The milk undergoes further concentration in unit 6; and the concentrated milk is removed from separator 7 through outlet 21. The vapour separated in separator 5 is used to heat unit 6; and the vapour separated in separator 7 is used to preheat the milk, which passess through unit 8 before entering the first evaporation unit through inlet 16.

Title: Improvements in and relating to a machine for making pressed glassware
IPC: C03B11/07
Filed: 1919-10-06
Abstract: 166,272. Moorshead, T. C. Oct. 6, 1919. Gathering molten metal; pressing.-Relates to a multiple automatic machine for the manufacture of pressed glassware. The main aim of the invention is the gathering and placing of the charge in the mould in an unchilled state. The moulds 112 are mounted on a continuously rotating frame, Figs. 1 and 2, and a suction gathering- device 53 is provided for each mould. The metal is pressed by a plunger 116, Fig. 28, in the usual way, and the finished article is removed by a rotary apparatus R, Fig. 1. The parts are operated by cams, in the well-known way, except the plunger, which is pneumatically operated. The gathering-device consists of a two-part cup 53 mounted on a frame 31 suspended from a lever 33 and balanced by a weight 36, Fig. 3. The air is exhausted from the cup 53 through a tubular valve 69, pipe 71, valve 84, and pipe 80. When the cup 53 is full, it is raised and the vacuum cut off bv the valve 69. The valve 84 is also closed to prevent leakage during the remainder of the cycle of operations. The bottom of the cup 53 is closed and the excess of metal cut off by knives 91, Fig. 29, of spherical form. By this time the cup 53 is clear of the tank 8. and the mould 112 is projected radially beneath the cup 53 on a slide 111, Fig. 29. The knives 91 are withdrawn, the cup 53 is opened, and compressed air is admitted to it to expel the charge into the mould 112, which is then retracted beneath the plunger 116. The ware is then pressed by the pneumatic apparatus 125, Fig. 3, and subsequently ejected by a movable bottom 154, Fig. 20. It is steadied by a recessed plate 159 until seized and removed by rotary grippers 179, Fig. 1, and placed on a conveyer &c. In the case of the finished article having a design on the surface which would interfere with satisfactory ejection, the mould is made in four segments which are opened radially prior to the rise of the bottom 154, thus freeing the design from engagement with the mould. The petition of the machine relative to the tank 8 can be adjusted by the gear shown in Fig. 2. Cooling-air enters by a central trunk 216.
