Title: Improvements in the lubrication of internal combustion engines of the sleeve-valve type
IPC: F01L5/16
Filed: 1923-05-15
Abstract: 223,845. Bonner, C. E. May 15, 1923. C h a n n e l s in cylinders and valves. -In internal-combustion engines having a sleeve valve 16 rotating between an inner cylinder 14 and and outer cylinder 11, spiral oil grooves 30 on the outer surface of the cylinder 14 a n d coacting grooves 31 on the inner surface of the valve are of opposite hand to raise lubricant from the reservoir 25 and distribute it over the rubbing parts. The groove 30 preferably extends in the direction of rotation of the valve 16. The grooves 31 are of less pitch than the grooves 30 and they extend only over the lower end of the valve 16. Lubricant reaching the top of the valve 16 passes outwardly through a clearance 32 and returns to the reservoir 25 between the outer surface of the valve 16 and the inner surface of the cylinder 11. Additional lubricant may be led to the rubbing parts by pipes 33 and by holes 36 in the valve. The reservoir 25 has an overflow orifice 28 to limit the oil level, the grooves 29 establish communication between the reservoir and the interior of the valves. Specification 221,841 is referred to.

Title: Remote radio control system
IPC: H04B1/12
Filed: 1954-07-22
Abstract: 750,384. Radio signalling. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. July 22, 1954 [July 28, 1953], No. 21382/54. Class 40 (5). In order to avoid the effects of interference on a control unit with remote radio control, the signal is periodically interrupted by short nosignal intervals. At a receiver, the no-signal intervals are separated and interference therein is used to disconnect the control circuit if it exceeds a predetermined level. At the transmitter, a low-frequency signal is interrupted under the control of a pulse generator and then modulates the radio carrier, Fig. 1 (not shown). In one receiver embodiment, the discriminator 18 produces a D.C. signal, the interruptions in which synchronize a multivibrator 19 which controls a switch 20 which connects the discriminator output to a control-signal circuit 20 during signal intervals and to a noise-signal circuit 21 during no-signal intervals. Circuits 20, 21 contain low-pass filters 23, 24, respectively, which remove the pulse frequency and feed the opposed windings 25, 26, respectively, of a relay 27. In the de-energized condition the contact 28 of the relay connects the. control unit circuit 29 to a local source 30 of control current, and in the energized condition the output of circuit 21 is connected to circuit 29. The winding 26 may be dispensed with and a circuit 31 provided to subtract the output 22 from output 21. In another modification, the circuit 29 is normally connected directly to circuit 21 or the subtraction circuit and the circuit 22 operates a relay to connect circuit 29 to the local source.

Preferably the mixed salts, e.g. the chlorides are treated with sodium carbonate in the presence of a small quantity of water at boiling temperature when a compact magnesium carbonate is obtained, or the magnesium salt is converted into an insoluble form by treatment with sodium carbonate at the fusion temperature in order to get a granular magnesia.  After separation of the soluble potassium and sodium salts by leaching with water they are employed or an ammonia soda process, for example of the Schreib type.  The sodium carbonate used to render the magnesium insoluble may be recovered from the resulting sodium bicarbonate.ALSO:The process for obtaining mixed potassium and ammonium chlorides described in Specification 210,399 by using Sylvinit or other mineral containing potassium and sodium chlorides instead of sodium chloride in one of the forms of the ammonia-soda process is modified by employing mixed salts of potassium, sodium, and magnesium as starting material, and by removal of the magnesium before treatment of the aqueous solution with ammonium bicarbonate.
