Abstract: A method for measuring capacitances using a measuring oscillator (10), whose cycle time is proportional to measured capacity (C M ) and reference capacities (C R1 , C R2 ) to be alternately connected to the input terminals (a, b) of a circuit that determines its frequency (f). The output of measuring oscillator (10) is connected to at least two cascade-connected dividers (11, 12); in the first one of these dividers (11) the oscillator frequency (f) is divided with one number (n) and in the second divider the once divided frequency of the oscillator (f/n) is further divided with another number (m). The frequency (f/n) divided with the first number (n) controls a logic unit (14), which controls switches (13a, 13b, 13c) that alternately and by pairs connect said capacities (C M , C R1 , C R2 ) to the measuring oscillator (10). Control pulse trains are directed from switches (13a, 13b, 13c) switching capacities (C M , C R1 , C R2 ) to the logic unit to inverters (15a, 15b, 15c), which are one by one connected to analog switches (16a, 16b, 16c, 16d) controlled by the output of the second divider. The outputs of analog switches (16a, 16b, 16c, 16d) are each connected to separate RC filters (17a, 17b, 17c, 17d), whose time constants (τ = R x C) have been fixed on such a high level that said RC filters also act as a holding circuit when no pulses are let to them by the analog switches (16a, 16b, 16c, and 16d). From the outputs of said RC filters it is formed a signal, which contains the information about the measured capacity (C M ), and a feedback signal (f), by which the operational voltage of said inverters (15a, 15b, 15c) is adjusted in such a way that at the same time the amplitudes of the pulse trains leaving said inverters (15a, 15b, 15c) are correspondingly changed.

Abstract: A method for treating a nail in order to increase the withdrawal load required to withdraw the nail from a piece of timber into which it has been driven. In accordance with the invention the nail is coated with a suspension containing a chelating agent so selected that, upon contact with lignin present in the timber the nail is bonded to the lignin via a chelate bond. The chelating agent comprises a modified polysaccharide in aqueous solution and is provided with a protective colloid to which the chelating agent has a lower affinity than to the lignin present in the timber. The suspension also includes a suspended polymeric thermoplastic resin to which the chelating agent has a lower affinity than to the protective colloid.

Abstract: Hot electron injection into the gate oxides of MOSFET devices imposes limitations on the miniaturization of such devices in VLSt circuits. A buried channel is provided to guard against hot electron trapping effects while preserving process and structure compatibility with micron or submicron VLSI devices. The channel current is redirected into a buried channel at a distance away from the interface in the vicinity of the drain region where the hot electron effect is most likely to occur. This redirection is effected by providing a buried, lightly doped region extending inwardly from the conventional source and drain implant profile regions.

Abstract: A basket (101) of vibratory screening apparatus comprises inflatable means (103) positioned to overlie a part of a screen member (105, 107) mounted in the basket. Inflation of the inflatable means (103) causes it to press against a screen frame (107) of the screen member, clamping it against a support (109, 129) of the basket (101). 
     The inflatable means (103) may be deflatable and a reservoir (119) may be provided for vented inflation fluid. 
     The screen member may be pre- or post-tensioned. 
     The basket (101) may comprise supports (129) and inflatable means (103) positioned to press against parts of the screen member remote from its periphery. 
     In another arrangement a clamping device for a screen member in vibratory screening apparatus comprises a frame member (1) on which is mounted an inflatable stocking (7). In use, the clamping device is inserted into the basket (21) of the screening apparatus so as to overlie the screen member, and the inflatable stocking (7) is expanded so as to press the screen member against a portion (17,19, 31) of the basket (21) while the clamping device reacts against a further portion (17,19,33) of the basket (21). This pressure from the stocking (7) holds the screen member in place. 
     The screen member may have a screen (13) mounted in a frame (15) and the stocking (7) presses against this screen frame (15). 
     The stocking (7) may press against the periphery of the screen member only or may press against other parts of the screen member as well.

Abstract: The system (1) includes a pre-cooler heat ex­changer (4) for cooling the refrigerant hot gas from the com­pressor (2) before entering the condenser (3) to render the entire evaporator (6) more effective for refrigeration purposes. The heat exchanger (4) for pre-cooling the hot gas has one passage through which the hot gas flows and another passage, in heat exchange relation therewith, which is connected to receive a small flow of liquid refrigerant bled off from the main stream of the liquid refrigerant which refrigerant passes through an expansion valve or capillary tube (55) to vaporize so that the re­frigerant hot gas is sub-cooled by the latent heat of vapor­ization of the vaporizing refrigerant. This heat exchanger (4) is located between the compressor and the condenser. The flow of the vaporized refrigerant used for cooling in the heat exchan­ger (4) is connected to the return flow of vaporized refrigerant flowing from the evaporator (6) to the compressor (2). This heat ex­changer (4) may be used alone or in combination with a direct ex­pansion liquid refrigerant pre-cooler (5).
