Abstract: Conventional sewage ejector systems include a standpipe into which effluent may drain and seep into the surrounding soil thus causing pollution problems. This device includes a sewage ejector nozzle connected to a discharge pipe and forming part of said pipe. The nozzle and pipe are detachably secured within a sealed standpipe so that when the system is not working, the effluent within the discharge pipe drains back into the standpipe and is contained thereby until the next discharge cycle commences at which time it is picked up by the effluent passing through the jet which includes a venturi restriction. When the effluent in the standpipe is all ejected, air is picked up and entrained in the effluent stream thus aerating the discharge effluent.

Abstract: Modulation systems for electrical signals representing music in which synchronous vibrato and tremolo modulations are applied to a flute signal in one channel, the vibrator being produced by a bucket brigade modulator and the tremolo by a balanced modulator in cascade with the bucket brigade modulator, and in which in a second channel tones other than flute tones, and pedal tones, are separately treated to have independent vibratos, and in which balanced modulators for modifying the amplitude of the tone signals are concurrently controlled by a common expression voltage. In one modification flute signals are vibrato modulated in opposed phases, and passed via diverse filters to a common tremolo modulator. Provision is made for combining the inputs of the channels, the outputs of which are electroacoustically transduced by separated loudspeakers. Provision is made for slowly varying the frequency of a sub-sonic modulating oscillator, which is either turned off, or operates at about 1 or about 6 Hz.

Abstract: A copying machine which can reproduce convex or concave surfaces having smaller radii of curvature at the edge than at the center, for example the surfaces of moulds for making contact lenses, has a cam assembly including a cam with a part-cylindrical cam surface mounted on a base. The cam has a part-circular section in the plane perpendicular to the cam surface generatrices and a straight section tangential to and continuous with one end of the part-circular section. The latter is slidably mounted on a concentric part-circular guide on the base, allowing rotary movement about its geometric center. The guide and at least the part-circular section of the cam have complementary square profiles. The part-circular cam section may be locked in position on the guide by screws threaded into the guide and passing through a concentric part-circular slot in the cam.

Abstract: A pallet for holding a printed circuit board on a conveyor in a solder wave machine which applies molten solder to the underside of the printed circuit board for completing connections, includes a pair of longitudinally extending first and second bars mounted on a frame, the bars including a pair of oppositely disposed longitudinally-extending grooves for receiving the opposite side marginal edges of the printed circuit board. Each one of the grooves is substantially channel-shaped and extends to the rear end portion of the bars so that the printed circuit board may be slipped into the grooves at the rear end portion of the bars to insert the board in position. One of the bars is transversely movable relative to the frame, and the other bar is fixed in position on the frame, the movable bar being fixed releasably to the first bar in an adjusted position to the frame for accommodating various different sizes of boards.

Abstract: A solid state electronic battery charger which is electromagnetically coupled to one or more batteries. A charging circuit energizes a drive winding to produce an alternating field received by an associated coupler and operative to convey charging current to a battery connected thereto. A sense winding monitors the level of the alternating field to derive a signal representative of the battery charge level and which causes a tapered charge to be supplied to the battery and an indication of a sensed fully charged state. A proximity sensor can be provided to denote the presence of a coupled battery and by which charging operation is commenced.

Abstract: A bus bar, for electrical switchboards comprises an elongated extruded imperforate metal bar of rectangular cross section having slots, with parallel side walls, extending the entire length thereof. Some of the slots are of T-shape cross section, each with the T-leg portion opening through a face of the bar. Others of the slots are rectangular grooves of generally uniform width, with smaller V-shaped grooves on opposite sides to accommodate threaded end portions of bolts or screws, and each opens through a face of the bar. T-bolts are arranged with their heads in, and slidable along, the full length of selected ones of said T-slots, respectively, to any desired position. The bolts have threaded stems, each of which extends from its associated head through the leg portion of the T-slot in which its head is disposed, and beyond that face of the bar through which the associated T-slot opens. Each stem is adapted to threadably receive a nut for clamping supporting or connecting brackets to the bar.

Abstract: A process is disclosed wherein the decaffeination of aqueous extracts of vegetable material with non-ionic, hydrophobic resin may be performed in a continuous manner. In accordance therewith, extract is contacted with resin to effect decaffeination, exhausted resin containing adherent caffeine and non-caffeine water solubles is bleached with water to remove the caffeine, the caffeine-free resin is then washed with a solution comprising water and an organic solvent to elute non-caffeine water solubles and then the resin is rinsed with water to permit its reuse in the further decaffeination of vegetable material extracts.

Abstract: A capping channel for a glass sealed unit adapted to be surrounded by a layer of polysulphide sealant. The channel comprises a rigid U-shaped member made of a thermally non-conducting polyvinyl chloride compatible with the polysulphide sealant. The member comprises ribs projecting from the inner surface of its base and adapted to penetrate in the sealant for increasing the retention of the channel to the unit. The ribs are set by pairs to form a V-shape and are provided with a lip extending from the free edge of the ribs, each lip of the pair being directed towards each other.

Abstract: A device for slidingly displacing or shifting a heavy load along a sliding comprises a platform provided with double-acting hydraulic jacks and resting on a guide rail. The platform is provided with hooks movable in a vertical direction and adapted to penetrate, when in their lowered position, apertures provided in the rail. Each hook has an oblique surface at the front end of the hook, which surface forms a sliding ramp adapted to slide on the front edge of an aperture wherein the hook is engaged. Each hook further has a locking surface at its rear end, which is adapted to cooperate with the rear edge of said aperture. The distance between any two adjacent ones of the apertures provided in the rail is at least substantially equal to the stroke length of the jacks, whereby the actuation of the jacks allows the load to be displaced by incremental movements.

Abstract: A safety guard for a press brake includes a sheet of rigid transparent material suspended by a pair of first cables from a frame of the press. A lower edge of the sheet is displaced a predetermined distance above a bed of the press providing just enough room so that a forward portion of a workpiece can be slid beneath the lower edge of the sheet and positioned on the bed of the press without providing additional space through which an operator's hands can be inadvertently extended. An operator holds a rearward portion of the workpiece with both hands as a ram of the press comes down during a work cycle to engage and fabricate or form the forward portion of the workpiece positioned on the bed. Just before the fabrication begins, a second pair of cables connected to the sheet and passing through a series of pulleys alternately on the frame and ram of the press operates, as a consequence to movement of the ram, to rapidly move the sheet out of the way of the workpiece.
