PURPOSE:To simplify the manufacture of a plate group for a lead storage battery by packing a paste into one surface of a retainer consisting of a nonwoven glass-fiber fabric before wrapping a grid-like base body made of a lead alloy in the retainer, followed by stacking thus formed plates to make a plate group. CONSTITUTION:A paste 2 composed of lead power and dilute sulfuric acid is packed into o...

A device for dispensing a thermally volatilizable substance in which a housing is formed with a linear open-ended, open top guide channel extending across the upper portion thereof. A window is formed in the floor of the channel and a heater is disposed below the window, providing a support for a member impregnated with the volatilizable substance. A grid spans the open top of the guide channel ab...

The storage element for electrical energy, for example a lead-acid accumulator, is equipped with positive and negative plates. These plates (1) are assembled such that they lie in vertical planes. The first conductors (3), which are connected to the active material, are horizontal. Vertical metal busbars (5) are used as internal current conductors. They extend from the top end of the storage eleme...

A method of intermittently dressing the ring-shaped surface or active rim of an axially adjustable dished grinding wheel of a gear grinding machine and which active rim acts upon a workpiece. The position of the active rim is controlled and the grinding wheel adjusted such that the ring-shaped surface or active rim is retained at the same location independent of its wear. The active rim is dressed...

The invention relates to a process for the preparation of pure acetoacetamide which is stable on storage, in which the reaction of diketene and ammonia is carried out under anhydrous conditions in the presence of aliphatic chlorohydrocarbons using an excess of diketene of 0.01 to 2 % of theory and at temperatures of < +10 DEG C. The stated amounts of excess diketene are in this case proportioned s...

PURPOSE:To run numbers of conveying cars simultaneously by mounting a control part on the self-running conveying cars, and transmitting information on conveying car operation to it from a main control part. CONSTITUTION:The conveying car 2 runs among plural stations ST installed at specific positions in an automated factory, and the control CT part 3 which indicates courses, order, etc., of operat...

A baseplate is mounted on the upper surface of the ski adjacent to the heel of the skiing boot and extends normally in the longitudinal direction of the ski and is rotatable on a vertical axis against a preferably adjustable resistance. A boot carrier is hinged to the baseplate at the forward end of the latter and holds the skiing boot so that the latter is only arbitrarily detachable. The rear en...

A cable is connected at one end to the skiing boot and at the other end to the ski. Detent elements are provided to hold the skiing boot in skiing position on the ski. A mounting fixture is secured to the ski approximately in the middle portion thereof and is connected to the cable. A tensioner is connected to the cable and causes the latter to hold the detent elements in engagement with each othe...

The tire building machine comprises a tire building drum or shaper, annular bladders adjacent each end and a bead setter and bladder pusher mechanism movable axially of the drum selectively to set a tire bead in proper position and to push and effectively roll the bladder when inflated to cause the ply edges of the tire to be wrapped about the bead without air entrapment and stitched securely. Suc...

A control process for a rotary pump which is immersed in a fluid produced by a well involves the use of a rotary pump driven by a variable speed motor and comprises the steps of acting upon the rotational speed of the motor according to a pressure difference which exists between the pressure of the fluid measured in the proximity of the pump and the production pressure of the well. The production ...

PURPOSE:To enable to cool effectively a pressure-welding surface between a brake pad and a disk brake, by forming a hollow part on the opposite surface of the brake pad in a piston body and a convex part entering into the hollow part is formed on an external wall of a calipers. CONSTITUTION:A piston body 19 is accommodated into a cylinder chamber 18 under a posture wherein a flat piston head surfa...

Catalysts for hardening aqueous alkali metal silicate solutions comprising mixtures of alkylene carbonate and methyl esters of organic acids are disclosed. The hardening catalysts are primarily useful in the production of high quality foundry molds and cores based on alkali metal silicate binders.

Security apparatus for detection of a security tag to be hidden in an article to be detected. The digitized waveshape of a tag signature signal preferably obtained by distortion of an oscillating magnetic field, (whereby the distortion signal being detected constitutes a signature signal) is compared with a stored digital representative of a signature signal, and an alarm enable signal is generati...
