Abstract: Abstract of the Disclosure A mobile street sweeper employs a pickup hood through which air is circulated to entrain and pick up debris.  The air circulation system includes a main blower and a smaller, auxiliary blower.  The main blower inlet is connected to the debris hopper of the sweeper and air delivered by the main blower is directed to one end of the pickup hood.  The other end of the pickup hood is con-nected by an air return line to the hopper.  A filter for fine material is mounted on the hopper and has an air inlet that is in communication with the exterior surfaces of a plurality of tubular filter elements in the filter unit.          The interiors of the filter elements are in communication with the inlet of the smaller auxiliary blower, which blower exhausts air to the atmosphere.  The system is arranged so that about 3/4 of the total system air flow is delivered to the hood by the main blower and about 1/4 of the total sys-tem air flow is exhausted to the atmosphere by the auxiliary blower, via the hopper and the filters.  The dif-ference between these flow rates is made up by air leaking in and under the flaps of the hood, and into the shroud of a curb broom, the shroud being connected to the full flow air return line leading from one end of the hood to the hopper.     -1a-

Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to the field of electrical connectors which utilize hollow shells and internal insert members.  It has often been difficult to accurately locate the insert members in exact pre-determined axial positions between and snugly against immovable stop surfaces of the shells, since the manufacture of the insert members usually results in some variation in the axial dimension.  Retention techniques utilizing adjustable stop surfaces on separate shell members or on separate retaining members add to the cost and complexity of electrical connectors.  Therefore, it is desirable to provide an elec-trical connector in which the insert member is retained between and snugly against immovable stop surfaces in which some variation in axial dimension in the insert member is permitted.  The present invention provides such an electrical connector, which includes a hollow housing member with an internal restricted passageway, an adjacent radial shoulder and a reference surface axially spaced from the shoulder oppositely to the passageway.  Also included is an insert member snugly retained against axial movement, between the shoulder and the reference surface.  The insert member includes a restraining surface in abutment with the shoulder, and shaped by plastic deformation of a weakened peripheral surface portion on the insert member by the wall of the restricted passageway.  The insert member before deformation includes the weakened peripheral surface portion and an adjacent pro-tective collar which protects the weakened portion from deformation until the collar has passed through the restricted passageway.

The groups are stored in a random access memory in use.  The device responds to specific white moves input.  If the input white move is the same as the stored corresponding white move, the device will display the next black move.  The user then decides upon hi  next white move, the play is continued until the problem is solved by the entry of correct white moves.

Abstract: Abstract of the Disclosure An acoustic diaphragm has a substrate of either a hard resin film or cloth of an organic material, and at least one side of the substrate is laid with a polyurethane elastomer layer.  In the case of a cloth substrate, the cloth is optionally metallized by evapo-ration deposition of Al or Ti and/or impregnated with a thermosetting resin.  The elastomer is a copolymer given by condensation of bifunctional polymeric alcohol and a glycol with a diisocyanate.  This diaphragm features a flat response curve at medium to high frequencies on account of its relatively large value for Young's modulus and adequately great internal loss, and accordingly is particularly useful for tweeters.

The improved fluid spray head has a plurality of circumferentially-spaced discharge orifices having cross-sectional areas which prog-ressively vary in a manner such that the relative cross-sectional areas of the discharge orifices are proportional to the square of the distance that their respective spray streams are desired to travel so that the perimeter of the ground area sprayed defines a preselected shape, and so that the ground area sprayed receives a substantially uniform coverage of fluid. The spray head also includes a means for simultaneously increasing or decreasing the size of all the discharge orifices so as to decrease or increase, respectively, the size of the area sprayed at a constant fluid flow rate, and thereby increase or decrease, respectively the precipitation rate over the area sprayed.  The spray head also includes a construction so that the rate of fluid flow to the dis-charge orifices can be adjusted by rotating the top of the spray head, and thereby also adjust the fluid pressure at the discharge orifice.  In a preferred embodiment, the spray head includes an inner tubular member which telescopes within an outer tubular mem-ber to provide the simultaneous adjustment of the size of the discharge orifices and wherein the inner tubular member is made radially thinner so as to be more pressure expandable under fluid pressure to thereby tighten the fluid seal between the inner tubular member and the outer tubular member.
