Abstract: ABSTRACT OF THE DISCLOSURE           Peat reconstituted by extruding and cutting to produce a cohesive, moldable mass that is smooth in texture and having a specific gravity slightly greater than 1.  A method of producing the reconstituted past is also described.           The method comprises removing sticks and other relatively large contaminants from peat moss dug from a peat bog and cutting and extruding the product to produce the reconstituted peat.  An apparatus suitable for producing the reconstituted peat moss comprises an auger having an inlet end and an outlet end.  Means to feed the peat moss to the auger at the inlet end.  A first extrusion plate positioned at the outlet end. A cutter abutting the extrusion plate so that the peat moss is cut as it leaves the first extrusion plate.  A blade on the second side of the cutter, remote from the first extrusion plate.  A second extrusion plate abuts the blades on the second side of the cutter plate.  As the peat moss enters the second extrusion plate, it is cut by the second cutter.                         - i -

Abstract: ABSTRACT      A printing device comprising a printing head, in which the ends of printing members facing a record carrier can be adjusted to a predetermined distance from the record carrier.  The distance member comprises a curved leaf spring which is connected to a contact member which contacts the record carrier.  The distance between the record carrier and the printing members (the printing distance) is adjusted by changing the curvature of the leaf spring.  The printing distance can thus be maintained at an as constant as possible value also in the case of thickness variations of the record carriers or wear of the printing members.

Abstract: TRAP FOR ANIMALS          Abstract of the Disclosure A trap for animals comprises a pair of pressure members each in the form of a rectangular frame with elongated sides and a plurality of parallel bars, the bars of one member being interspaced with those of the other member to prevent disengagement.  These members are pivotally mounted on a base to form a triangular passage.  The base also consists of a frame having elongated sides and a plurality of parallel bars extending therebetween.  Springs act between the base and pressure members to urge them from an up- to a down-position.          A locking device, including a portion for carrying bait, so as to be releasable by an animal in the passage, normally keeps the members in their up-position.  When released the members move down and retain the animal in the passage.

Abstract: ABSTRACT              A flat disc is provided with pie-shaped segments of gear teath running from the periphery towards the center of the disc in parallel relationship separated by blank segments on the face of the disc. First and second pinion gears are positioned over the face and coupled for movement towards and away from the center of the disc simultaneously along splined shafts.  The geometry is such that when one of the pinion gears is in meshinq engagement with a toothed segment, the other pinion gear is positioned over a blank segment.  The pinion gears are thus alternately driven by the toothed segments and a change in speed ratio between the rotating disc and pinion year shafts is effected by varying the radial distance of the pinion gears from the center of the disc.

Abstract: ABSTRACT OF THE DISCLOSURE Resilient O-ring seals for the annular spaces defined when a radi-ally inner surface of a cap is projected axially into the radially outer sur-face of a fuel tank filler neck having an axially outer annular lip.  The radial width of the annular space is less than the radial dimension of the O-ring.  Each O-ring includes an annular, radially outwardly facing groove defined by an axially inner lip, an axially outer lip, and a connecting web portion.  The inner and outer lips both include axially inner and outer sur-faces.  The web portion includes generally radially inwardly and outwardly facing surfaces.  As the O-ring moves axially into the annular space, the axially inner surface of the inner lip contacts the neck surface and is urged axially outwardly in a wiping action causing bending moments to be established in the ring such that the O-ring radially inner surface is urged resiliently in a "rolling" motion.  Such resilient rolling motion radially compressively seals the annular space.  In one embodiment, the axially inner surface of the outer lip contacts the neck surface as the O-ring is projected axially fur-ther into the annular space.  The axially outer lip of the annular ring there-by compressively seals the annular space axially.  In other embodiments, the axially outer surface of the inner lip and the axially inner surface of the outer lip are provided with annular, axially extending compression rings or beads.  Axially outward deflection of the inner lip brings the inner lip com-pression ring into contact with one of the walls defining the annular groove, thereby creating an additional seal.  In two of these "compression ring" embodiments, the compression ring on the outer lip cooperates with the com-pression ring on the inner lip to create the additional seal.  The compression ring on the outer lip does not contact the neck surface unless the first and second surfaces are misaligned.

An electromechanical transducer controller connected to the towing vehicle brake system develops an electrical signal which varies continuously and systematically in accordance with braking action pressure in the towing vehicle brake system.  In a fluid trailer brake system, an electromechanical control receives this signal, and con-tinuously and systematically varies the fluid pressure in the trailer brake system accordingly.  A vacuum or other fluid power booster can be included to assist in amplifying and applying this fluid brake pressure.  Trailer braking action in caliper-type trailer disc brakes varies in accor-dance with this fluid pressure.

Abstract: IMPACT MECHANISM An impact mechanism operated with gaseous fluid under pressure fed from a source of fluid having a casing with an inner cylindrical space. A piston is accommodated for reciprocation within the cylindrical space of the casing to divide the space into a work stroke chamber and an idle stroke chamber. The chambers are communicated to the source of gaseous fluid through a distribution means for reciprocation of the piston under the action of fluid. A valve is provided over the inlet port of at least one chamber to admit gaseous fluid under pressure thereto. The valve comprises a helical compression spring mounted coaxially with the inlet port of the chamber. One end of the spring is tightly sealed and the other end is fixed over the inlet port of the casing. Gaseous fluids under pressure is admitted to the chamber through gaps between the turns of the spring when the spring is expanded, and the admission is interrupted when the spring is compressed. There is also provided a working implement received in the casing and operated by the piston.
