Shrimps may be passed down into a severing device (5) which as a unit may effect such a reciprocating movement that rod members accommodated in the device sever the shrimp into a roller-like head portion (20) and a disc-like body portion (21). In a separator device (6) in which a number of radially directed roller planes consisting of a big inner cylinder (29) and a number of smaller cylinders (30...

In an apparatus for the grinding or polishing of workpieces, particularly metallographic samples, the grinding or polishing pressure is transmitted to the workpiece through a deformable transmission link which is strained by strain gauges of an activating member, which is then immobilized. The apparatus comprises means for sensing the elastic deformation of the transmission link and changes of tha...

High molecular weight viscoelastic polymers are dissolved by passing the polymer solution through a die which "beads" the polymer allowing the formation of very fine filaments which are drawn into the flow. The beading and flow rate are balanced to maintain constant fine filament formation.

A hydraulic control system for a continuously variable transmission for an automotive vehicle, the transmission having a first and a second variable-diameter pulley provided on respective first and second shafts, a belt connecting the first and second pulleys, and a first and a second hydraulic cylinder for changing effective diameters of the first and second pulleys. The control system includes a...

Particulate styrene polymers containing blowing agents are prepared by a process in which an aliphatic hydrocarbon of 7 to 9 carbon atoms is added in an amount of from 0.01 to 0.5% by weight, based on the styrene polymer, before, during or after the polymerization. The particulate styrene polymers can be processed to foam blocks and moldings having a satisfactory smooth surface.

A printed circuit board base prepreg material is provided of a porous, expanded polytetrafluoroethylene (PTFE) membrane or fabric impregnated with a polyimide resin varnish. Upon curing, a printed circuit board base material of porous, expanded PTFE impregnated with polyimide resin is provided. The base material of the invention may be laminated to a glass fabric to improve strength and dimensiona...

Improved reexpandable shrunken foam bodies of styrene-acrylonitrile type resin possessing an ability to reexpand to the original volume of the highly foamed state when left standing at room temperature under atmospheric pressure and a method for the manufacture of such reexpandable shrunken foam bodies. The aforementioned shrunken foam bodies are obtained by causing a styrene-acrylonitrile type re...

Pellets of a chlorinated vinyl chloride resin composition comprising inorganic materials, a solvent and a blowing agent; a pre-expanded particle of a chlorinated vinyl chloride resin comprising inorganic materials and a solvent and a process for preparing the pre-expanded particle of the chlorinated vinyl chloride resin containing inorganic materials which comprises kneading a chlorinated vinyl ch...

The present invention relates to a liquid suspension of a high molecular weight, water-soluble polymer or water-soluble salt prepared by admixing and water-soluble polymer with a hydrocarbon carrier fluid and a suspending agent comprising an aqueous emulsion of a copolymer comprising a water-insoluble and substantially hydrocarbon-insoluble polymer consisting of particles having a dry weight avera...

In a compatible recording and reproducing apparatus which is capable of recording and reproducing information on both a video disk and a digital audio disk, a relative angle between an optical axis of a laser beam emitted from a pickup and the disk is adjusted so as to be suitable for the disk loaded on the apparatus. Further, the movement of the pickup in the radial direction of the disk is regul...

In a device for braking gearwheels, the braking produced by a braking element at low speeds is reduced or avoided at higher speeds by the fact that the braking element (4) consists of a friction ring which is secured on the gearwheel (3) and rests with an undersize, by an obliquely inclined portion (5), on the shaft (1) at low speeds.
