Abstract: ABSTRACT     A clamp structure has a clamping band with at least one plastically deformable so-called "Oetiker" ear to be contracted to tighten the clamp structure about the object to be fastened.  To assure a relatively smooth, gap-free transition in the circumferential direction within the area of overlap, for example, of inner and outer band parts, a tongue portion is provided at a free end of the inner part to engage in a corresponding aperture in the respective outer part when the ear is contracted.  The result is a clamp structure that avoids leakage problems that have been experienced in the past.

Abstract: AIR DISPENSING APPARATUS         ABSTRACT       A system for obtaining precise inflation to a desired pressure setting of pneumatic tyres comprises a pressure transducer which provides an output voltage proportional to its input pressure determines the output frequency of a voltage/frequency converter.  The output of the voltage/frequency converter is gated into a counter for a set period determined by a timer unit so that in such period the counter assembles a count which is a measure of the sensed pressure.  The timer unit is adapted to divide down the local a.c. mains supply frequency so as to derive therefrom discrete timing pulses enabling cyclic operation of the apparatus within a predetermined timing framework.  A user has the facility to enter a pressure target into the apparatus and, during each cyclic operation, a comparison is effected between the pressure sensed by the transducer and the set target pressure and, depending upon the outcome of this comparison, a pressure increment or decrement is affectuated as appropriate by operation of an inflate or exhaust valve.  Compensation for trans-ducer and/or voltage/frequency converter drift is described, together with variants such as for enabling extra large tyres to be rapidly inflated.

Abstract: Abstract A joint sealing structure for use in sealing relatively axially movable members of a joint over a wide range of such axial movement includes a seal ring having a sealing lip having a maintained dynamic seal with a sealing surface of one of the joint members.  A stiffener is provided for transferring biasing force from a spring to the sealing lip.  The stiffener may be provided with a flexible connecting portion permitting free movement of the sealing lip under the biasing action of the spring over the range of movement between the joint members.  In one form, a base may be provided to which the connecting portion is mounted, the base being fitted into the counterbore of the joint member so as to provide a static seal therebetween.  The base may be provided with a turned flange for carrying the outer portion of the spring for free movement of the spring in maintaining the biasing action. The spring may comprise a Belleville spring arrangement to pass over center over the range of movement of the joint members so as to provide an effectively constant spring biasing force to the sealing lip.  The arrangement has the advantage of simplicity of construction.

Abstract: ROTATING DISC SPLITTER            ABSTRACT   A method and apparatus for splitting wood slabs substantially along the wood grain into longitudinal-grain wood strands are provided. The apparatus comprises a rotating disc splitter having a pair of parallel rotary shafts each having centered thereon and secured thereto a series of spaced apart circular discs, means for counter rotating the shafts to pull a slab of wood between the series of discs and to split the slab into strands, and a series of floating spacer rings on each shaft interspaced between the discs, the floating spacer rings being positioned on either side of the shafts adapted to permit the spacer rings to move away from the discs when a slab is being split therebetween. The method comprises inserting an end of a slab of wood between counter rotating discs, a first series of discs pushing first sections of the slab in one direction perpendicular to the direction of travel of the slab and perpendicular to the axes of the counter rotating discs, a second series of discs interfitting with the first series of discs pushing second sections of the slab between the first sections in an opposite direction to the one direction thus causing splitting to occur between first sections and second sections of the slab and forming strands, and guiding the first sections and second sections of the slab downstream of the counter rotating discs to issue as substantially straight strands from the counter rotating discs.

Abstract: P2242. 8-P ABSTRACT OF THE DISCLOSURE The disclosure relates to a combination feeder and sifter for particulate material. The apparatus includes a vertically elongated hopper for holding a bulk supply of the particulate material. A vibratory unit is positioned below the hopper and is movable independently thereof. An upper panel of the vibratory unit constitutes a bottom-forming panel of the hopper and is in direct contact with the bulk supply of particu-late material. The bottom-forming panel has an adjustable feed rate device thereon which, when the vibratory mechanism is in operation, provides for a controlled rate of flow of particulate material from the hopper onto a vibrating sifting screen supported directly underneath the panel. The configuration and arrangement of the supply hopper and the bottom-forming panel are such that the mass of particulate material affecting the operation of the vibratory panel approximates that of an imaginary conical pile of the material. The apparatus permits a single vibratory drive unit to carry out both feeding and sifting operations simultane-ously.
