Abstract: Abstract of the Disclosure Increased knob pull resistance in a cylinder lock is obtained by providing the knob sleeve with an inner lug which engages in a bayonet slot in the key-actuated rollback cam sleeve so as to transmit knob pull to the cam sleeve and through such sleeve and its out-turned rollback cam to the fixed hub.  Preferably, the resulting increased pull resistance is combined with that provided by forming the knob sleeve with a small stud which rides in a groove in the hub to transmit pull directly from the knob sleeve to the hub.

Abstract: ABSTRACT     A bandpass filter comprises a line interconnecting input and output terminals.  Three stubs are connected to the line at three different locations at a spacing which is 1/8 the wavelength of the centre frequency of the passband.  Each stub is grounded at one end and open at the other and each stub has a total length which is 1/4 the wavelength of the centre frequency.  The two outer stubs are connected to the line at a position on the stubs which is 1/6 the wavelength from the grounded end.  The middle stub may be connected to the line at a position on the stub which is either 1/4 the wavelength of the centre frequency or 1/8 the wavelength of the centre frequency.  The filter operates to provide greater rejection of waves double or treble the passband .

Abstract: ABSTRACT OF THE DISCLOSURE      An improved automatic paper feeding device for a facsimile equipment or the like apparatus is disclosed which includes a feeding roller     disposed below the feeding end part of an inclined paper feeding board and a reversing roller     located above the feeding roller     in a line contact relation to be rotated in the opposite direction to that of drawing of papers from the paper feeding board    , the reversing roller being rotatably supported at the free end part of side plate members      adapted to turn about a support shaft .  A connecting line between the shafts       of the feeding roller     and the reversing roller     extends substantially at a right angle relative to a connecting line between the shaft     of the reversing roller and the support shaft      for the side plate members .  The direction of tension given by an endless belt      for rotating the reversing roller     is selectively determined to extend substantially at a right angle relative to the connecting line between the shafts       of the feeding roller     and the reversing roller     whereby contact pressure to be exerted on the feeding roller    by the tension of the endless belt      via the reversing roller     becomes practica-lly zero.    Thus it is assured that the device is operated without any extra contact pressure active on the feeding roller while fluctuation in conact force is minimized.

Abstract: Abstract The invention relates to a method for evaporation of a solution in a recompression evaporation plant.  The solution (9) is evaporated first in known manner by indirect transfer of heat from the recompressed vapour (13) through condensation of said vapour in one or more evaporation units (1).  After pre-evaporation in this fashion the solution (10) is finally evaporated by direct transfer of heat from the overheated vapour (8) which is obtained by recompression (6) of the vapour (15) formed in evaporation.          According to the invention this final evaporation is achieved by mixing (7) the solution (10) in finely-divided form with the overheated vapour (8) and then after thermodynamic equilibrium between the vapour and liquid phases has been substantially attained separating (2) the solution (11) from the vapour (18).  The solution (11) thereby obtained can be further evaporated without the addition of heat but with a reduction of pressure by means of conducting it to an expansion vessel (3) which is connected by a vapour line (20) to the suction line (15) of the compressor (6).

Abstract: ABSTRACT OF THE DISCLOSURE           A bin sorter for lumber comprising a plurality of bins to receive the lumber.  A feed conveyor brings lumber to the conveyor and the lumber is distributed to different bins, depending on predetermined lumber characteristics.  There are bin bottoms for each bin for the lumber movable in tracks up and down the bin.  The sorted lumber feeds from the bottom of the bin.  Each bin bottom can move downwardly as each bin load increases and can be raised to the top on unloading of the bin.  The bin bottom is of low profile so that it may be raised close to the top of the bin and thus close to the feed conveyor, so that the lumber falling onto the bin from the feed conveyor falls only a short distance.  An arm is pivotally mounted at the bottom of the tracks and arranged to be pivoted downwardly by a bin bottom moving downwardly to contact the arm.  The arm acts as a gate to contain lumber in the bin but below the end of the guide member as lumber is unloaded, by bridging the gap between the lower end of the bin and the bin bottom at its lowermost position.  The arm is urged to the raised position when the bin bottom is raised. The bin provides for low lumber drop.

Abstract: SOLENOID VALVE ASSEMBLY          Abstract of the Disclosure A solenoid valve assembly has a slidable valve member which responds to a selectively energizable solenoid coil and a spring to control the opening and closing of pressure and exhaust ports through movement of the valve member.  When the pressure port is fully opened, the valve member is seated against a solenoid stop and port member. The solenoid stop and port member includes a central flow passage which serves as the exhaust passage for the valve assembly.  The flow passage is surrounded by a valve seat area which includes a frusto-conical surface having a recess or groove formed therein.  The frusto-conical surface and the groove therein reduces the flow forces imposed on the valve member which generally operate to assist seating of the valve member.  By reducing the flow forces, the unseating force necessary to open the exhaust port is reduced resulting in lower spring and magnetic forces.
