Filed: 1945-01-26
Abstract: 588,852. Bread-making. LUNDSTROM, K. E., and SVENSSON, A. B. Jan. 26, 1945. No. 2077. [Class 28 (i)] In pricking dough passing between rolls 2 and 3 by pins on the periphery of the roll 2 the pins are kept free of adhering dough by brushing rolls 7 and 8 which also contact each other and have different speeds. The smaller brush roll 8 cleans the upper part of the pins while the brush roll 7 gets down to the periphery of the roll 2. The brush roll 8 receives dry flour from hopper 5 through a distributor 6 and applies it to pricking roll to prevent dough adhering to the pricking pins. All the rollers are driven by inter-meshing gearing but the' roll 3 may be driven from 2 by a friction disc 9. The power drive may be communicated first either to the roll 2 or to the roll 3. Specification 588,853 is referred to.

Title: Improvements in boundary layer control in aircraft
Inventor: LJU SVENSKA TURBINFABRIKS AKTI
IPC: B64C21/02
Filed: 1946-01-23
Abstract: 639,117. Boundary layer control ; thrust spoiling. SVENSKA TURBINFABRIKS AKTIEBOLAGET LJUNGSTROM. Jan. 23, 1946, No. 2257. Convention date, Sept. 28, 1945. [Class 4] [Also in Group XXVI] In aircraft having jet propulsion or like units the compressor controls the boundary layer of the aeroplane, preferably that of the wings (by acceleration, sucking and/or blowing off), and is also employed for the simultaneous reduction of the propelling reaction force or for providing a braking reactive force, which latter operation may be performed by means as described in Specification 638,063. In the construction shown in Fig. 1 suction is applied to two conduits 15, 16 of a wing 2, for sucking in air through slots 25, 26 on the wing surfaces by connecting the conduits through valve-controlled mouths 17, 18 to the channel 29, which supplies air from intakes 3 to the compressor 4 delivering air to the combustion chamber in front of turbine 5 ; during normal propulsion the mouths 17, 18 are closed by valves 27 (one for each wing) which are opened manually, or by a pressure receiving plate 30, to allow suction to occur and are turned back to serve also as closure members for channel 29, thus reducing air supply to the combustion chamber and so reducing the propelling force. In a modification . conduits receiving pressure from the output side of compressor 4 are connected to discharge slots in the wings for moving boundary air. In Fig. 8 is shown a lever 55 for the simultaneous control of the pivoted gas-discharge deflector members 11 and 12, (shown in position for producing a forward braking discharge stream in the direction of arrows 6) arid of the closure valves for the suction 15, 16 for the boundary air control. In a modification the deflector members are on horizontal pivots (instead of vertical pivots as in the case of members 11 and 12 shown in Fig. 8) so that a partly downward direction of the forwardly directed gas-stream may be obtained for landing. Automatic means such as a suspended rod may be provided on the undercarriage to shut off the actuating mechanism for controlling the boundary layer when landing. Another reaction jet control means, shown in Fig. 12, comprises a conical member 110 axially movable to close the exhaust outlet 9, valves 101 and 106 being opened together to allow forward gas discharge through lateral conduits 100 ; valves 107 normally closing suction conduits 108 are connected to valves 106 so as to be opened as the latter move to open the forward end of conduits 100 and close the inlets 3.
