Abstract: 677,532. Starch. AKTIEBOLAGET SEPARATOR. June 27, 1949 [June 26, 1948], No. 16957/49. Class 121 In making, starch from maize, rice, wheat or other cereals the starch-bearing material, suspended in a liquid, is purified and washed in two or more stages in centrifugal separators from which the separated fractions, e.g. a starch concentrate and a predominantly impure fraction are discharged continuously, the second stage and any succeeding stages, which may if necessary include a de-watering stage, being carried out at a temperature higher than that of the material admitted to the first stage. The temperature of the starch concentrate may be raised, e.g. above 40‹C, at or after the first stage and may be kept constant or raised still further in subsequent stages, but the temperature should never exceed the gelatinization temperature for any appreciable time. The concentrate may be subjected to mechanical working after each separation and may be heated by the washing liquid. When heated in the bowl of the separator, the temperature of the concentrate may exceed the gelatinization temperature for the period the concentrate is in the bowl, its temperature thereafter being reduced below gelatinization temperature.

Title: Mechanism for controlling the in-feed movements of machine tool carriages
IPC: B24B47/04
Filed: 1957-05-29
Abstract: 810,997. Grinding. STUDER MASCHINENFABRIK A.G., F. May 29, 1957 [June 1, 1956], No. 17074/57. Class 60. Mechanism for providing an in-feed of a machine tool carriage without backlash and for obtaining accurate in-feed end positions of the carriage without backlash and at constant pressures, is characterised by a toggle lever mechanism which is adapted to provide the in-feed movement and which is operable by a control member, the carriage being applied without backlash to one moving part of the toggle lever mechanism by means of a force opposed to the in-feed movement and by a stop device which fixes the end position of the carriage in the extended position. A workpiece 4, e.g. the gauge cylinder of an internal limit gauge, which may or may not rotate, is ground by a grinding wheel 2 mounted on a carriage 3 movable on the machine frame 1 by a toggle 7a, 7b operated through a push-rod 11, by a cam 6 on a shaft 5 rotated manually or automatically alternatively the toggle may be operated hydraulically. A spring 17 urges the carriage 3 backwardly so that the rear end of a pin 13 mounted in the carriage abuts a rod 8 to which the toggle link 7a is pivotally connected. The toggle link 7b is pivotally connected to a rod 9 having a head 9a normally held against the machine frame 1 by a spring 10. When the toggle is straightened, the carriage 3 is moved until the front end of the pin 13 abuts a stop 16 on the machine frame 1; the head 9a of rod 9 is forced away from the machine frame 1 and the spring 10 urges the front end of the pin 13 against the stop 16. The rod 13 is screw-threaded in the carriage, and can be rotated by gearing 14, 15 to compensate for wear of the grinding wheel 2. The spring 17 takes up backlash in the screw thread and in the toggle.

Title: Improvements in or relating to direction finding radio beacons
IPC: G01S1/02
Filed: 1940-12-05
Abstract: 546,238. Directive wireless systems. AGABALTIC RADIO AKTIEBOLAG. Dec. 5, 1940, No. 17323. Convention date, Nov. 28, 1939. [Class 40 (v)] A transmitting beacon for providing an equisignal course line comprises a pair of aerials connected at spaced points to a feed line, a switch operated by complementary signal currents being arranged to short-circuit the line at its connection to one of the aerials. Means may be provided for avoiding key clicks. The shortwave source 10 is connected by a line 11 to two dipoles 12, 14 spaced apart about a quarter wave length or an odd multiple thereof. When both are energized directly, radiation is a maximum to the right, and a minimum to the left, the polar diagram being approximately a cardioid. When the switch 16 is closed by the relay 17, the dipole 14 is not directly energized and the polar diagram is reversed. An equi-signal course is thus set up in a direction perpendicular to the plane containing the dipoles 12, 14. Relay 17 may be controlled by a cam 26 on a rotary shaft operating a switch 29. In order to avoid clicks in the receiver as the switch opens and closes, the source 10 is short-circuited at these moments by a condenser consisting of fixed plates 32, 33 and movable plates 36, the latter being formed as suitably-placed lugs on a disc fixed to the cam shaft. In a modification (Fig. 8, not shown) the lugs 36 operate a switch which is arranged to impose momentarily a prohibitive bias on the grid of the output valve of the source 10. The dipoles may be replaced by open quarter-wave aerials, one of the wires of the line 11 being connected to an earthing net (Fig. 6, not shown). The Specification also describes known arrangements in which a source energizes an open aerial and a frame aerial, the feed to the latter including either a receiving switch, or a resistance bridge which is unbalanced in opposite direction by operating a shorting contact placed across part of the resistance in one of the arms (Figs. 1 and 2 not shown).
