Abstract: In a medium-sized drill hammer in which the percussive mechanism (3) and drive motor (5) are perpendicular to one another, a compact, handy structural shape is to be obtained with adequate gear reduction. This is achieved in that the spur gear (20) of the first intermediate shaft (4) meshes with toothing (22) of a second intermediate shaft (23) arranged on the upper side of the first intermediate shaft (4) facing the percussive mechanism (3). A further reduction is obtained via an annular gearing (30) having a bevel-toothed ring gear (26) and a pinion (29). A space-saving design is primarily achieved by arranging the motor pinion (29) in the free space between the first intermediate shaft (4) and the ring gear (26). The drill hammer is suitable, owing to its long handle (8) and its increased driving power compared with small drill hammers, for working with drilling tools up to 30 millimetres in diameter. <IMAGE>

Abstract: The present invention relates to the coproduction of a combustible gas stream usable as an energy source, a sulfur-dioxide-containing second gas stream usable as a source of oxidant in the gasification of coal, and a sulfur-dioxide-containing third gas stream usable as a feedstock for the production of sulfuric acid. The process includes heating coal in a coal gasification zone in the presence of an oxygen and sulfur dioxide-containing atmosphere under partial coal gasifying conditions to produce a carbonaceous char and a crude coal gas stream. Sulfur-containing compounds are removed from the coal gas stream and converted to elemental sulfur. The carbonaceous char is combined with gypsum to form a feed mixture. The non-gypsum portion of the feed mixture contains sufficient reducing potential to release substantially all of the sulfur in the gypsum as gaseous compounds of sulfur in a +4 or lower oxidation state. The feed mixture is heated under reducing conditions to produce a sulfur-dioxide-containing second gas stream recovered at an early stage of the reaction, a sulfur-dioxide-containing third gas stream and a solid sintered product. The sulfur-dioxide-containing second gas stream is recycled back to the gasification zone to provide the oxidant for the coal gasification.

Abstract: The circuit comprises for a charge-coupled device (CCD) delay line a semiconductor substrate (4), a CCD delay line (1) formed on the semiconductor substrate, and first and second registers (2,3) each having substantially the same maximum charge handling capacity as that of the CCD delay line. An input portion of the first register is given the same structure as that of the CCD delay line, and output portions of the first and second registers have substantially the same structure each other. A control circuit acts on the second register (1) so that an output signal from the latter becomes a signal corresponding to the maximum charge handling capacity. A comparator circuit (5) analyzes the output signals of the first and second registers, and produces an output signal which is fed back to an input source of the input portion of the first register (2) so that the output signal from the first register becomes equal to the output signal from the second register. A high level clock signal voltage is supplied to an input gate of the first register, and a voltage of the input source of the first register is supplied to an input source of an input portion of the CCD delay line (1). Thus, an overflow of charge can be avoided satisfactorily.

Abstract: Before the press moulding of thermoplastics reinforced with glass fibre mats, it is necessary to make the glass-mat thermoplastic blanks in sheet form plastic and mouldable by heating them up outside the press. To achieve high component qualities and low production costs, in this case as high a preheating temperature as possible with a fast heating-up time should be achieved. Heating equipment is proposed, comprising a stack 3 of heating plates arranged one above the other with displaceable frames 2 lying inbetween and provided with restraints 18 for the blanks 19. The heating plates 1 engage in the frames 2, so that a very dense packing is achieved. For charging and unloading the frames 2, a lifting mechanism 4 for the stack 3, a holding device 5 for the heating plates 1 and a displacing device 6 for the frames 2 are provided and interact. <IMAGE>

Abstract: The invention relates to synchronous motors having a starting device, the rotor (4) of which synchronous motors, excited by permanent magnets, can be coupled to a load, for example to the impeller (11) of a feed pump (8) after a rotation play has been passed through, the one coupling part consisting of a cylindrical ring (13), which is provided with stops (15, 16) that act in both motor rotation directions and is arranged axially with respect to the rotor shaft (7), and the second coupling part consisting of a driver (14) placed inside said ring (13) of the rotor shaft (7). In order to make such synchronous motors also suitable for relatively large drive powers without this leading to destruction of the coupling arrangement (12), it is intended that the cylindrical ring (13) be produced from a rubber-elastic material and advantageously be inserted into a component, for example the rotor (4), which surrounds said ring in the form of a sleeve and carries out force transmission via its circumferential surface. <IMAGE>

IPC: G11C14/00
Filed: 1991-11-08
Abstract: A ferroelectric random access memory device contains columns of ferroelectric memory cells, each column of memory cells being coupled to a distinct bit line. Each memory cell is selectively coupled to a corresponding bit line by an access control transistor so that only one memory cell in the column is coupled to the bit line at a time. To read the data stored in a selected memory cell reads, the cell is strobed twice, separately sampling the output voltage generated each time. Since the first read is a destructive read, the second read operation always reads the cell in its "0" state. Then the two sampled outputs are compared, and if the first reading exceeds the second by at least a threshold amount then a "1" output value is generated. Otherwise a "0" is the output value. In a preferred embodiment, the time delay between strobing the memory cell and sampling its output is made longer the first time that the cell is read than for the second time that the cell is read. In this way, if the cell is storing a "0" bit, the first read will produce an output voltage that is smaller than it would have been had the first read not been delayed, which helps to ensure that cells storing "0" bit values are properly sensed.
