A battery grid pasting machine has an endless steel conveyor belt (80) for advancing grids beneath a paste hopper (132). The lower end of the hopper is closed by an orifice plate (170). The top run of the belt is supported by a vertically adjustable roller (82) directly beneath an orifice slot (194) in the orifice plate (170). A guide assembly is provided for advancing the grids in a downwardly in...

The metering of the yarn (14) which is drawn off and is to be wound onto spools (15) is carried out at each work unit (5) of the machine by means of a pulse counter (2), in which pulse counters (2) periodic pulses are transmitted (during active operation of the work unit) by a central system (1) which has an independent pulse transmitter (11) and an actuating element (16) for preselection of the c...

Apparatus for spreading manure comprises an elongate hopper 12 mounted on a mobile frame. An axial feed rotor 18 runs along the inside of the base of the hopper and urges manure forwardly to a transfer rotor 25 which pushes the material sideways through an opening 21 to an overshot impeller 23 which throws the manure sideways from the apparatus. On the axial feed rotor 18 are blades 19 extending o...

A product line is provided for forming a sheet product composed of products such as bacon slices resting on a pre-cut thin substrate such as a sheet of paper. The substrate sheets are pre-cut to a predetermined length, and a flow of individual products and a flow of pre-cut sheets are coordinated such that the products deposit onto the pre-cut sheets in a predetermined pattern. The line may also i...

A GaAs semiconductor device comprises a Si substrate (1), an intermediate layer (3, 4) formed on the substrate and a GaAs layer (2) grown on the intermediate layer. The intermedite layer includes constituent GaP/GaAsP and GaAsP/GaAs superlattice layers and additionally AlP and AlGaP thin films.

The present invention concerns a bipolar storage battery. The storage battery (10) consists of bipolar elements (12) in consecutive mutual contact, each element comprising a plate (13) of electrically conductive material which has been coated on one side with a positive active compound (14) and on the other side with a negative active compound (15); of separator plates (16) containing electrolyte,...

Disclosed is a method for stopping and starting a reactor equipped with a heat exchanger, a catalyst settler, a catalyst filter and the like, which method is suitable for use in a process for the preparation of acrylamide by reacting acrylonitrile with water in the presence of a metallic copper-based catalyst used as a suspended bed. According to this method, various undesired phenomena which may ...

A safety ski binding for holding the tip of a ski boot and capable of releasing sideways has two side jaws (13, 14) which hold the ski boot at the sides; a sole hole-down member (15), and a release spring (11) which extends substantially in the longitudinal direction of the ski. The release spring is braced at one of its ends against the binding housing (12) which is fixedly mounted to the ski and...

PURPOSE:To prevent the generation of a malodor, by piercing a gas gathering pipe and a garbage pressure introducing pipe through the air dome provided above a garbage reclaiming hole and connecting the end part of the garbage pressure introducing pipe to the screw type garbage pressure introducing pump arranged to the outside of the air dome. CONSTITUTION:A garbage recovery vehicle 8 is directly c...

PURPOSE:To enable mass production of ultrafine short metallic fibers as a base material to be used for composite material at a low cost by pressing a metallic block of a raw material to the surface of a circular grinding wheel contg. fine hard grinding abrasive grains while rotating said wheel.
