Title: Evaporator
Inventor: BUTZINE CHARLES J
IPC: B01D1/22
Filed: 1950-04-19
Abstract: <PICT:0681394/III/1> <PICT:0681394/III/2> <PICT:0681394/III/3> The evaporating surface of a film evaporator, which may be used for drying plastic materials and suspensions of solids in liquids such as brewer's slurry, is scraped by one or more blades which move over the surface, the edge of each blade being formed by a series of straight sections with gaps between them, and by plough-like projections substantially spanning the gaps between the straight sections.  These projections lift the material being dried, and turn it over in front of the adjoining straight sections.  The evaporators, shown Fig. 2, comprises a cylindrical surface 2 surrounded by a steam-jacket 4. Four blades 19 connected to spokes 17 by pivoted supports 18, are moved over surface 2 by means of a rotating shaft 10.  The edge of each blade has a series of projections 30, Fig. 3, formed by cutting the edge at an angle and bending out small triangular sections. These projections extend ahead of the blade in the direction of its motion.  The series of projections of each blade is offset with respect to those of the other blades, Fig. 5, so that the projections collectively plough-over the entire evaporating surface.  The material-to-be-dried is introduced at the bottom of one end of the cylinder; it spreads over and is ploughed upon, the heated surface 2, and moves spirally to the opposite end of the cylinder where it is discharged through a tangential outlet at the top.  The blades are made of flexible material, and the flexibility is increased by means of perforations 29 which also allow any piled-up material to pass through the blades.

Title: Photographic exposure control mechanism
IPC: G03B9/58
Filed: 1969-02-24
Abstract: 1,249,384. Shutter control arrangements. HATTORI TOKEITEN K. K. Feb. 24, 1969 [Feb. 28, 1968], No. 9711/69. Heading G2A. The exposure terminating member 39 of the shutter described in Specification 1, 249, 386 makes a preliminary movement towards its exposure terminating position for daylight exposure operation, but is held in its initial position for flash exposures. The control circuit, Fig. 2, enables the electromagnet 50 to be energized to thus hold member 39 by actuation of switch 5 1  if the photo-resistor 56 indicates insufficient light for daylight exposure and if the flash circuit consisting of bulb 56, switches 51 and 55 and pilot lamp 57 indicate that the flash circuit is in an operative condition. If sufficient illumination is present or if the flash circuit is faulty then the closure of 51 does not effect the energization of the electromagnet 50, the continued movement of release lever 1, Fig. 1, causes the nose 5 thereof to engage lever 36 to commence the movement of member 39, the subsequent closure of switch S 2  renders transistor T 2  conductive to energize electromagnet 50 and stop the movement of member 39. In daylight operation, the opening of the shutter opens contacts S 40  to start operation of an RC timing circuit formed by capacitor 57 and the photo-resistor 56, after the measured time, transistor T 2  is rendered non-conducting to de-energize electromagnet 50 and thus close the shutter. In flash operation, the opening of the shutter closes contacts S 41  which completes the flash circuit, the sudden drop in voltage on firing of the bulb being sufficient to de-energize the electromagnet 50 and close the shutter. Switch S 5  is closed only if member 39 does not make an initial movement.

Abstract: 298,621. Fulton, O., (Assignee of Fultograph Ges. Apparate und Zubeh÷r f³r Bild- Rundfunk und-Telegraphie, (formerly Telectograph Ges.). Oct. 13, 1927, [Convention date]. Copying-telegraphs.-Signal currents are converted into, or caused to produce or control, current or voltage impulses having a comparatively gradual rise .and fall, to eliminate injurious changes which otherwise take place during amplification and other processes. When a feeler A is on an insulating portion of the picture to be transmitted, bias is applied by a battery B2 through a resistance R2 to the grid of a valve V so that no anode current flows, and when the feeler is on a conducting portion, bias is applied to the grid by a battery B1 through a resistance R1 and across the resistance R2 so that anode current flows. The signals are modified by the charging and discharging curve of a condenser C in conjunction with the resistances which may be variable. An alternating-current is superimposed on the signal current by a transformer T1 and the output is taken from a transformer T2. When the signal is shaped at the transmitter as described, no modification is necessary at the receiver.
