Abstract: ABSTRACT         A novel paving slab, particularly for use outdoors or in areas where efficient drainage of water from the pavement surface is required. The slab comprises a composite of upper and lower superimposed layers bonded together, the upper layer being water-permeable and comprising a granular dispersion in a bonding medium and the lower layer comprising a closed-cellular, soft-foamed plastic material  having a plurality of openings distributed therethrough.  This arrangement overcomes the disadvantages of prior art structures that water inadequately drains from the paving surface and becomes trapped in the pores of the material.

Abstract: ICE SKATE MANUFACTURE          Abstract Ice skate blades each having a main portion and an enlarged head are cut from contiguous areas of steel stock by cuts spaced such that each cut forms the upper edge of the main portion of one blade and the lower edge of the main portion of the next blade with the head portions cut alternately from those portions of the stock extending be-yond the ends of the main portions.  An upwardly extending lug is secured to the upper edge of one end of each blade to extend longitudinally towards the other end and a bolt is secured to or engages the other end of the upper edge and extends in the same direction as the lug.  The upper edge of the blade is received in a downwardly facing groove in a skate superstructure with the groove having a slot at one end of the superstructure to receive the lug and with the bolt extending through a hole in the other end of the superstructure and having a fixing portion on the free end of the bolt for securing the blade in the groove.  The fixing portion may be the head of the bolt or a nut and is received in a cavity in an external surface of an end wall of the superstructure.  The structure pro-vides a skate with a smooth and hence safe end, while at the same time a fixing portion that is readily accessible.

Abstract: ABSTRACT OF THE DISCLOSURE   A control mechanism through which pressurized fluid from a source is communicated into a brake system and a steering system in response to independent operator brake and steering signals.   The control mechanism has a housing with a first bore and a second bore therein.   A piston located in the first bore separates a first chamber and a second chamber. A spool valve located in the second bore separates  brake pressure chamber created therein from a series of lands that control the flow of the pressurized fluid through the housing.   When an operator effects a brake application, the piston moves in the first bore and creates a brake pressure in the  first chamber.   The brake pressure which is communicated to the brake pressure chamber in the second bore linearly moves the spool valve and allows pressurized fluid to be communicated to the second chamber in the first bore.  The pressurized fluid in the second chamber acts on the piston and provides a power assist to aid in the development of the brake pressure during a brake application.  When an operator turns the steering wheel of the  vehicle, rotary torque is transmitted through an input shaft to a torsion member connected to a pinion which engages a rack in the  steering system.  Rotation of the input shaft causes a restriction in the flow of the pressurized fluid from the housing to a piston attached to the rack in the steering gear.   The restricted flow causes a pressure differential to be created across the piston to provide a power assist in moving the rack.   The movement of the rack is transmitted to rotate the spool valve and maintain the restrictive flow condition for the duration of the operator steering signal.

Abstract: ABSTRACT OF THE DISCLOSURE           A collapsible support structure for supporting items, such as chair backs.  The support structure, in an erect position, has two vertical members interconnected at their bottoms by a collapsible, preferably horizontal, member.  Each end of the horizontal member is also pivotally connected to the other vertical member by a diagonal support member that extends between each end of the horizontal member and an upper portion of the opposite vertical member. When the structure is erect, the diagonal support members form an "X".  Stiffening members, which are preferably generally vertical, are spaced from the vertical members and extend between the horizontal member and the diagonal support members.  Both the horizontal member and the diagonal support members are formed of a plurality of pivotally interconnected links, at least one of which is modified to maintain the links in a desired angular position when the support structure is erected.  Collapse of the support structure moves the vertical members towards each other to reduce the width of the structure.  The collapsible support structure is combined with similar or other types of support structures to form folding devices.

Abstract: ANTI-PUMP CIRCUIT BREAKER              ABSTRACT OF THE DISCLOSURE         The circuit breaker is taught with an anti-pumping control circuit.  If the circuit breaker closes on a fault and quickly reopens without the closing switch being either mechanically or electrically released in the interim, reclosure of the circuit breaker either by an automatic recloser or by the mere fact that the closing switch remains closed will be prevented until the closing switch is once again opened.  In addition, if the closing switch is actuated prior to power being applied to the circuit breaker control system, the circuit breaker will not close when power is applied.  The closing spring will be charged, however, for a subsequent circuit breaker closing after release and reactuation of the closing switch.

For some ores, the floats can be made on each fraction, after desliming thereof, which are obtained by screening over a 35 mesh screen.  For other ores, desliming and a rougher flotation are initially needed.  The silica froths (rougher tails) from this float are then cleaned and recleaned in separate floats, without additional conditioning or addition of collector to produce tails which are discarded and a combined sink which is screened over a 48 mesh screen to produce a +48 mesh fraction which is discarded and a -48 mesh fraction which is concentrate (product).  Depending upon the ore, the sink from the first float is directly usable as product or is screened over a 35 mesh screen to produce a -35 mesh concentrate (product) and a +35 mesh fraction which is conditioned with fuel oil, treated with a frother and collector, and floated to produce a tails, which is discarded, and a third concentrate as product.
