Abstract: ABSTRACT OF THE DISCLOSURE        A solid composition comprising a homogeneous mixture of a solid thermoplastic resin and from 1 to 80 weight % of at least one microbiocide which is insoluble in water, is readily dispersible or soluble in the resin at temperatures sufficiently high to permit plastic manipulation of the resin and the dispersion or solution of the microbiocide is sustained indefinitely upon cooling to ambient temperature while the diffusivity of the microbiocide in the resin under such conditions becomes vanishingly small, retains its micro-biocidal activity in the resin and does not degrade or react with the resin in which it is dispersed.  This composition provides a convenient non-toxic dosage form of the micro-biocide which is subsequently mixed with a second thermo-plastic resin at a concentration of about 0.5 to 15 weight % to obtain a homogeneous resin composition containing an effective amount of the microbiocide.

Abstract: Applicant:     Nicholson Manufacturing Company Title:       Feed Works For Rotary Ring Log Barkers ABSTRACT           Chain type log transports are located at the infeed and outfeed sides, respectively, of a rotary barking ring and are constructed to be positioned as close as possible to the barking ring to transport logs of minimum length through the barking ring.  The transports include flights with centrally depressed portions, which flights are mounted by their tips on spaced conveyor chains so as to minimize the radius of the area traversed by the flights adjacent to opposite sides of the log-barking ring to enable the flights to be placed as close as possible to the log-barking ring.         The radius of the arcuate flight paths is further minimized by the flights being tapered in cross section away from their log-cradling sides to avoid interference between adjacent flights as they turn through their arcuate paths adjacent to the opposite sides of the log-barking ring.

Abstract: Abstract A heated fluidized bed is formed by rotating a body of sand in a horizontal cylindrical drum, lifting and dropping sand from the bed through the open portion of the drum, and heating the region through which the sand drops.  The drum is formed by a cylindrical water wall of pipes connected to a water source and a steam outlet, and annular end plates hold the sand bed and define inlet and outlet openings in the drum.  Waste material is simply dumped through the inlet opening and ash is automatically discharged through the outlet opening.  The sand is preferably lifted by small cross section, scoop-like baffles so that the coolest sand from the bottom of the bed is heated, and waste particles are not removed from the bed.  If desired, auxiliary air can be introduced into the sand bed through a manifold-pipe arrangement.

Abstract: ABSTRACT OF THE DISCLOSURE     Each of paired pivot mechanisms pivotally holding a window sash within a supporting frame comprises a stationary base screwed to one of the constituent members of the support-ing frame and a pivot-carrying movable base fitted over the stationary base.  By manipulation of a pair of adjusting screws the movable base and thus the pivot can be adjustably moved relatively to the stationary base in the longitudinal direction of the supporting frame member,i.e. in a selected one of mutually opposite directions generally parallel with the plane defined by the supporting frame and radial relative to the pivot.  If desired, the spacing between the two bases can also be adjusted, by manipulation of the same pair of adjustment screws, in a direction which is axial relative to the pivot.  The mechanism is equally applicable to either vertically or horizontally pivoted windows and presents an improvement of the possibility of utilizing one adjustment means for adjusting the pivot both radially and axially thereof.

Abstract: A B S T R A C T A scatter type of smoke detector wholly supplied by a dry cell battery includes a clock circuit applying energy pulses to an LED light source which directs light pulses on a smoke sensing path.  Light pulses scattered by smoke generate detection pulses in a photo diode whose a amplitude is dependent on the smoke density.  The clock pulses and detection pulses are applied to a control circuit including a dual, data-type flip-flop logic circuit and a threshold circuit driving an alarm horn.  If the smoke density, and hence the detection pulse amplitude, exceeds a predetermined level the control circuit energizes the alarm in a continuous mode.  If the battery drops below a preselected level the control circuit is actuated in an inter-mittent mode.

Abstract: ABSTRACT OF THE DISCLOSURE            An improved pressure control valve which provides equal damping force in both directions of movement of the valve spool and which also provides negative feedback to partially negate fast transients leading to valve insta-bility.  The pressure control valve includes a valve body having an inlet chamber and an enlarged adjacent damping chamber.  A valve spool is received within the chambers, the spool having a first portion and a second radially outwardly extending portion adjacent the first portion and disposed within the damping chamber.  As the valve spool is shifted to an open position fluid will be expelled from the damping chamber through a first orifice, and as the valve spool returns towards its closed position fluid will be expelled through a second orifice, the orifices having cross-sectional areas proportionate to the volume of fluid being expelled so that equal damping will be obtained in either direction of movement of the valve spool.  The valve spool is provided with an orifice passageway which permits fluid in the inlet chamber to be in communication with fluid in the damping chamber whereby transient peaks in the inlet may be transmitted to the damping chamber to provide for negative feedback.

Title: Method of manufacturing bonded products of cellulose  or cellulose derivatives
Inventor: AKESSON ARNE
IPC: C08J3/28
Filed: 1978-07-05
Granted: 1981-12-08
Abstract: Abstract In a method of manufacturing bonded products, comprised completely or partially of cellulose or a cellulose deri-vative, such as saw dust, wood chips, paper or vegetable fibres, a condensation resin between an aldehyde, preferably formaldehyde, and urea, melamine or a phenol type is used as an adhesive. The product is irradiated to at most 5 Mrad with ionising radiation. Then the material will undergo a certain cross-linking. Residual quantities of uncured ad-hesive substances are reduced at the same time. The radiation dose is adjusted so that residual quantities of aldehyde in the material will be reduced. Preferably, also the residu-al quantity of formaldehyde in the material is reduced. By adding additives containing olefinic, acrylic or comparable groups the extent to which cross-linking takes place is increased.
