Title: High speed rotor bearing - has heavy duty bearings and internal self lubrication
Inventor: RAJSIGL ZDENEK
IPC: D01H4/12
Filed: 1991-02-14
Abstract: A high speed bearing with inner lubrication consists of two circular boxes which are welded together. A tube runs through the bore where the box flanges are welded, and the open ends are sealed with a packing and cover. The central axle through the tube, runs on the bearings, held in cages fitted into each of the boxes, and which also revolve on the bearings. The two round boxes (1,2) have flanged ends (11,12) which have a bore smaller than the bearing cages (6). The bearings are assembled through gaps (13) in a section of the box circumference similarly, the interior spaces (16,17) contain absorbent material which is soaked with lubricant. These fit over the tube (14) which surrounds the axle (4) and between the two bearings cages. The tube (14) has a cut out section (15) close to the gap (13), so that additional lubrication may be added, and which will seep to the two bearings. USE - As a high speed self-lubricating bearing for a rotor spinning machine.

During the opening and closing movement of the mould, a suction holding pin (3) can be moved in a position coaxial with the male (1) and female mould (2), whereafter the entire mould (2) is divided into a base section (9) retaining its momentary position and a movable section (22) which is pushed on a partial region of the suction holding pin (3) to take the envelope foil (18) and held there by suction via a suction slot (20) and then moved back to the base section (9) and reunited with it to form the entire mould (2). The suction holding pin (3) is then pivoted out of the intermediate space again by moving the female (2) and male mould (1) together and the suction slot (20) is closed by pressure between the female (2) and male mould (1). The advantage of the invention lies in the simplification of the injection moulding device while at the same time simplifying the cycle of movements in the injection moulding process.

Patent DE-4221309-A1 (DE)
Inventor: GREUTER FELIX DR
IPC: H01C7/02
Filed: 1992-06-29
Abstract: The current limiting element consists of an electrical resistance body (3) which is arranged between two contact connections (1, 2). This resistance body (3) contains a first resistance material which has a PTC characteristic. Below a limiting temperature, the first resistance material has a low cold resistivity (specific resistance) and at least one current-carrying path running between the two contact connections (1, 2). Above the limiting temperature, the first resistance material has a hot resistivity which is high in comparison with its cold resistivity. Such a current limiting element is intended to be distinguished by a homogeneous switching capability and a high rated current-carrying capability, despite simple and cost-effective construction. This is achieved in that the resistance body (3) additionally contains a second resistance material having a resistivity which is between the cold resistivity and the hot resistivity of the first resistance material, and by the second resistance material being fitted with intimate electrical contact with the first resistance material and forming at least one resistor which is connected in parallel with at least one subsection of the at least one current-carrying path. <IMAGE>

Title: Device for grating chocolate or the like
Inventor: HAEMMERLE MARTIN
IPC: A23G1/04
Filed: 1993-04-01
Abstract: A device (1) is used for grating chocolate. It has a knife rocker (6) with two rasping knives (4, 5) fitted to the latter. The said knives (4, 5) are arranged alongside but at a distance from one another and are acted upon by the lower end face of a block (2) of chocolate situated in a mounting. A reciprocating movement of the rasping knives (4, 5) causes chips of chocolate to be removed from the underside of the block of chocolate. Between the two rasping knives (4, 5) there is situated an adjustable support for the block (2) of chocolate, by means of which the thickness of the chips can be adjusted. A design with two rasping knives makes it possible to cope with a relatively small angle of swing, even for relatively large blocks of chocolate, making it possible for the external dimensions of the device to be compact (Figure 1). <IMAGE>
