Bowling pins are conveyed consecutively in an essentially horizontal plane along a common path alongside of which are loading bins, one each for the reception of a pin in a spotting position, the pins being conveyed along the path for transfer into the first available empty bin, the conveyors being preferably rubber ropes or belts with deflectors which are electrically controllably operated to def...

A machine is shown for conditioning a tire carcass for recapping wherein the tire is rotated while the crown is rasped to size and then a feeler is dropped onto the rasped crown surface while the tire continues to rotate. The feeler rides on this rasped surface to control the application of power driven shoulder rasping means to the carcass, the shoulder rasping means being operative on the opposi...

An electric storage battery includes a plurality of cells within a container, each cell comprising a cell pack of substantially planar plates interleaved with separator material. The two end surfaces of each cell pack engage respective planar spacer members 2, 10 which in turn engage either an end wall or an intercell partition of the container. The two spacer members 2, 10 are integrally connecte...

A valve adjustment unit for an electronically controlled hydraulic proportional-response valve comprising a proportional-response magnet unit, a coaxially connected electronic control unit, and an intermediate insulating spacer body surrounding the inductive coil of a displacement transducer. The magnet core of the transducer is carried by the push rod of the armature of the proportional-response ...

A continuous, completely jacketed countercurrent centrifugal extractor of the type utilized to mix and separate two liquids that have different specific gravities and enter through separate inlets. The extractor has at least one overflow weir in a mixing zone between the inlet for the specifically lighter and the inlet for the specifically heavier liquid phase and a division of the mixing zone int...

A method and device for fine profiling or shaping tools coated with super-hard material, for example cubic crystalline boron nitride or diamond, especially tools coated with a single layer and having a prescribed or predetermined profile or shape. The rotatably driven tool is profiled or shaped in the region of the cutting surface by a clustered electron or laser beam which is controlled in a cour...

For the purpose of providing improved spliced connections, the wall of the splicing channel (14) has a plurality of alternating elevations (23) and depressions (22) which extend in the longitudinal direction.

A synergistic mixture of (1) 3-methyl-4-amino-6-phenyl-1,2,4-triazin-5-one and (2) pyrazon or lenacil or benzthiazuron or azolamid plus lenacil or phenmedipham or 2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulphonate has a particularly broad and selective herbicidal activity in beet crops. Preferably, 0.1-5 parts by weight of (2), in particular 0.1-3 parts by weight, are used per ...

A heat wave shielding lamination consisting of at least two In2O3 shield layers containing different amounts of Sn is provided on the surface of a glass substrate to provide shielding against heat waves without causing heat wave pollution in the surrounding environment. The amount of tin contained in the respective layers increases with increasing proximity to the substrate. The heat wave shieldin...

The liquid-tight and air-tight covering (10) consisting of a plastic film and intended, in particular, for mattresses of hospital beds has lateral parts (16) formed from three film layers (22, 23, 24). The inner and middle foil layers (22, 23) are provided with air passage openings (22', 23'). For purification of the air flowing in and out, for example, from aerosols, bacteria and the like, filter...

Compositions for application to the interior surface of the tread of a pneumatic tire to facilitate relative movement between contacting portions of the interior surface when the tire is driven deflated, comprise a polybutene, an acrylic polymer or a polyolefin as a gelling agent for the polybutene, and a particulate solid puncture sealing material. Preferred gelling agents are polyethylenes, espe...

Process and apparatus for providing digital data indicative of the contour of a leaf-like article, e.g. a tobacco leaf, and the flaws (holes) that it may comprise, from a video signal composed of image lines. The video signal is coded by comparing same with thresholds so as to detect transitions. The number n of points pertaining to a hole is compared with a threshold n1, firstly within a line X, ...

A ski binding comprising two lateral clamps (4, 4') mounted displaceably under the action of a resilient member parallel to the plane of the ski (3) between a closed position in which the clamps coact with the sole of the boot and an open position. These clamps have when viewed from above a forwardly converging shape flaring rearwardly; the portion of each clamp adapted to coact in closed position...

Foundry moulds or cores are made by a method comprising mixing a granular refractory material with a potassium alkali phenol-formaldehyde resin binder solution, forming the mixture and curing the formed mixture by gassing with a 1-3C alkyl formate. Cure by gassing with a formate, particularly methyl formate, enables rapid and efficient production of foundry moulds or cores. The formates used have ...

Stable non-aqueous dispersion of water-soluble polymers of extremely high molecular weight coupled with relatively low viscosity and rapid dilutability with water to form a polymer solution are obtained by polymerization of at least one water-soluble alpha , beta -monoolefinically unsaturated monomer such as acrylamide and dimethyl aminoethyl methacrylate in water-in-oil emulsion with the aid of ...

PURPOSE:To improve attraction of a movable iron core of an electromagnetic brake by providing thereto a rod having one end received in a hole formed in a stationary iron core for slidable movement therein and the other end affixed to the movable iron core so as to effect the application and release of the braking force by the vertical axial movement of the rod.
