Abstract: METHOD OF MAKING A PRODUCT FOR DISPENSING A VOLATILE SUBSTANCE                   ABSTRACT OF THE DISCLOSURE          A method of making a product, which holds and dispenses a volatile substance, comprises the steps of advancing a backing material, a reservoir material and a third material, that is permeable to the volatile substance from respective supplies into close proximity to each other with the reservoir material lying between the backing and permeable materials.  The volatile substance is then supplied to the reservoir material to be absorbed thereby.  The three materials are fused together in a pattern defining a closed loop periphery to seal the reservoir material between the backing and reservoir materials at the periphery and thereby form the product.

Abstract: ABSTRACT         In cultivating or rolling soil by a wheel packer with several hinged interconnected frame sections, each having a set of rolls on a common shaft, rotatably journalled at the ends of downwardly dependent arms the rolls closest to a hinge will not roll the soil at all or too loosely in case of irregular or uneven ground.  To avoid this inconvenience the arms are pivotably and preferably also resiliently mounted on the frame in addition to which the arms are slightly rotatable or twistable about its longitudinal axis to allow a deviation from horizontal of the shaft which thus may follow the irregularities of the ground so that the packer rolls the soil very efficiently.

Abstract: ABSTRACT OF THE DISCLOSURE             The present invention provides a system for overriding the prior art automatic levelling system for vehicles riding on fluid suspensions such as air bags.  Such systems utilize a link extending between the vehicle axle and a regulating valve whereby the valve is responsive to vertical axle movement to alter the pressur-ization of the air bags and hence the clearance height between the vehicle bed and the axle.  In the present invention the link is replaced by a cylinder and piston actuator which is connected to a master control via a conduit.  An incompressible fluid fills the actuator chamber, the conduit and the master control chamber.  The master control chamber may be varied in volume to produce a corres-ponding change, via the fluid, in the actuator chamber resulting in relative movement between the actuator cylinder and piston and hence operation of the regulating valve.  By appropriately operating the master control it is possible to selectively effect pressurization or bleeding of the air bags to raise or lower the vehicle bed and hence achieve a desired elevation of the vehicle bed relative to a reference elevation.  The invention permits rapid adjustment of the vehicle bed elevation to bring it parallel to, for example, the loading dock of a warehouse to speed the loading or unloading process.

Abstract: Abstract of the Disclosure Supersonic flow of a molecular gas under the appropriate conditions through an expansion nozzle, produces homogenous condensation of the gas.  If the gas is vibrationally excited, the condensation is inhibited.  Thus, selective vibrational excitation of an isotopic species in the gas provides a means of controlling the condensation of the gas. Such selective vibrational excitation may be readily accomplished by means of later irradiation of the super-sonically flowing gas.  The controlled condensation in turn may be used as the basis of isotope separation and enrichment by subjecting  he stream of gas and condensate particles to aerodynamic processes whereby the condensate particles are separated from the main flow of the gas.

Abstract: ABSTRACT OF THE DISCLOSURE     An integrated switching and transmission network comprises a digital switching system for transfering communication information without congestion.  The switching consists of one-way switch modules which are connected through two-way time division multiplex transmission links to link modules each including a control unit for establishing communication paths within an associated line group as well as for controlling the switch in cooperation with the control units of other line groups.  Each of the switch modules is allotted to two of the two-way links and comprises a time stage and a signalling logic circuit.  The input of each module is connected exclusively to one way of one of the two-way links, whereas the output of each module is connected to the other way of the other two-way link.  For the reliable control of the network, transmitting control units generate signals.  Each signal addresses one of the signalling logic circuits, which converts the signal to an operation signal by which the associated time stage is operated or to a signal intended for the receiving control unit.  Furthermore, control messages are transferred between the control units through the time stages.  The time stages carry out the required time inter changes for the transfer of said control messages and communication information between the line groups.

Abstract: ABSTRACT                        GAMES  RACKETS     The invention relates to games racket frames which are made from reinforced plastics material and have a hollow construction.  The particular construction and method of the invention enable a satisfactory hollow product to be made by an injection moulding technique instead of the more laborious technique of building a suitable reinforced hollow construction around a mandrel.      The frame is a hollow injection moulding of reinforced thermoplastics material in which the walls (21A and 21B) at the outer and inner circumference of the head (21) are joined by support means (25) through which the stringing holes (23) pass.  The support means are integrally formed during the moulding.      The method of the invention involves the use of a fusible core (10) which is shaped to provide the desired moulding with support means and which is melted out after the moulding is formed.
