Patent FI-982455-A (FI)
Inventor: PIIRAINEN OLLI
IPC: H03G3/30
Filed: 1998-11-12
Abstract: The invention relates to a method and an apparatus for implementing automatic gain control in a system where an analog signal is converted into a digital signal. The apparatus comprises means (208) for performing automatic gain control of the adjustable signal in an analog manner using a gain control step of predetermined size and means (446, 448) for performing inverse gain control of the digitized signal in such a way that, after the digital adjustment, the power of the signal is the same as before the analog adjustment. To enable an accurate gain control, the apparatus further comprises means (410, 412, 214, 420) for determining the maximum energy of the signal during a predetermined measurement period, means (426, 428) for comparing the determined maximum energy to preset threshold values (430, 432), and means (436) for performing an automatic gain control of the analog signal and a compensation for the gain control to the digital signal, if the measured value exceeds the threshold.

Title: Improvements in valve operating mechanism for internal combustion engines
IPC: F01L1/06
Filed: 1926-01-15
Abstract: 256,470. Howard, H. J. Jan. 15, 1926. Valves; valve gear.-A split-ring valve 1 sliding in an annular space between the cylinder and cylinder head is actuated by a cam disc 12 working between rollers 19 carried by a frame 14, which slides upon rods 13 and is formed with a pair of diverging arms 17 connected to rods 4 secured to opposite sides of the valve. The rods 4 are formed with shoulders engaging the upper edge of the valve, and with lugs 8 entering slots in the valve, and are secured to the valve by screws or rivets 11. Leakage along the rods 4 is prevented by glands 5 of asbestos secured between countersunk washers 6 allowing side play. Another arm 23 on the frame 14 may actuate a beat inlet valve 22 in cases where the valve 1 controls only exhaust; or the valve 1 may control both inlet and exhaust. In a modification, the valve 1 bears against packing-rings on the cylinder head, in which case the glands 5 are unnecessary. The cam rollers 19 are provided with annular grooves in their larger ends forming ball races, the balls bearing against washers 20, by varying the thickness of which adjustment may be obtained. In multicylinder engines, a single cam shaft serves for two adjacent cylinders, the shaft for one pair of cylinders being driven in the opposite direction to that of the next pair. Specification 190,473 is referred to.

Patent GB-563943-A (GB)
Title: Dentifrices
IPC: A61K8/22
Filed: 1943-01-25
Abstract: A dentifrice comprises an oxygen supplying component consisting of a peroxide, percarbonate, perborate of an alkali or alkaline earth metal, or a complex compound containing hydrogen peroxide and a salt of an alkali or an alkaline earth metal; boric acid and a solid straight chain hexahydric alcohol.  The preferred alcohol is mannitol.  In cases where sodium perborate is used in the presence of the boric acid, it is necessary to use the monohydrate.  The hexahydric alcohol is used in sufficient amounts to combine with the boric acid in the presence of the water present during the use of the dentifrice to form a reagent of substantially greater acidity than the boric acid.  The boric acid and the alcohol are present in the proportions necessary to produce a predetermined alkalinity, which should lie between pH 7.5 and 9.
