Abstract: ABSTRACT      A portable electric hammer drill incorporates an electric motor 12 disposed close to the handle 13 of the tool and with its axis of rotation at right angles to the axis of rotation of the drill bit holder 10, and a gear 15 on the motor shaft meshes with a first pinion 16 driving the holder in rotation.  A second pinion 25 meshes with the first pinion 16 and drives the driving piston 30 of the mechanism for transmitting impacts to the holder.   The axes of rotation of the holder 10, the first and second pinions and the gear 15 are coplanar, and the first and second pinions are on diametrically opposite sides of the said gear, the first pinion being nearer the handle.   This arrangement enables the motor to be placed nearer the handle than if the first pinion were in dire t mesh with the said gear, and thus improves the balance of the tool.   The arrangement permits the diameters of the first and second pinions to be selected independently of each other.

Abstract: ABSTRACT OF THE DISCLOSURE       The invention concerns a method and circuitry for refreshing data stored in a dynamic MOS memory.  The refresh-ing process proceed independently of data handling in the memory.  The duration between successive two refreshing pro-cesses is selected such that is is smaller than a predeter-mined maximum duration by a duration which is associated with a memory process.  When during a refreshing process, a reading process is to be executed, the reading process is delayed by means of inserted holding cycles.  During execu-tion of memory processes, the execution of a refreshing process is delayed until the memory process is concluded. In the case of a simultaneous appearance of signals which precede a refreshing process and a memory process, a decision unit determines a sequence of execution of the processes.

Abstract: ABSTRACT OF THE DISCLOSURE         A pressure release device for an internally pressurized fluid container has a dome-shaped inwardly concave closure element circumferentially joined to one end of the tubular container side wall.  The closure element is deep drawn of tempered steel, with a circular central area spaced from an annular outer area by an annular intermediate area traversed by radially extending L?ders Lines.  A tab member is located in the central area.  The tab member is partially circumscribed by a single weakened circular line of reduced material thickness, with the ends of the line being separated by a connecting area of substantially undisturbed material thickness and strength.  The closure element has a structural integrity which reacts to an increase in fluid pressure in the container above a prescribed level by undergoing at least a partial eversion extending from the annular outer area, across the annular intermediate area into the circular central area to initiate a fracture of the closure element along the weakened line of reduced material thickness. The connecting area remains intact during any resulting outward deflection of the tab member occasioned by fluid escaping from the container through the fracture.

Abstract: ABSTRACT OF THE DISCLOSURE Method for forming conductive, transparent coating such as may be used on the interior surface of a vitreous tubular member.  In a carrier gas and exterior to the member to be coated, there is formed a vapor from a material substantially comprising organic tin halide compound having a predetermined condensation temperature and a predetermined decomposition temperature, with the temperature of the carrier gas and the formed vapor main-tained between these temperature.  The member to be coated is heated to a temperature greater than the decom-position temperature of the organic tin halide compound and the heated carrier gas and formed vapor are longitud-inally flowed through the heated tubular member.  Upon contact with the heated tubular member, the vapor breaks down to form the transparent conducting coating  The carrier gas and residual heated vapor are flowed out of the member being coated and are cooled to condense and collect the residual material.  There are also provided very high performance fluorine-doped tin oxide coatings.

Abstract: ABSTRACT OF THE DISCLOSURE    A pair of transistors, alternately activated by a low frequency generator, alternately connect the positive and negative terminals of the monitored DC source to the common bus of the ground detector apparatus.  Each produces a fault current signal flow through any ground fault existing on the other source terminal, with the return circuit including a permanent ground rod, the input of a comparator, and apparatus common.  An opposing reference current signal of preselected level is applied to the comparator input, at the same time as each fault signal, from a current pump network driven by the low frequency generator.  If each reference current signal is larger than the corresponding fault current signal, the com-parator output is a square wave signal of alternate plus and minus pulses which is applied to a negative voltage generator network controlled by contacts of two synchronizing relays alternately driven by the low frequency generator.  If the comparator square wave output is synchronized with synchron-izing relay operation, a registry relay is held energized to indicate the absence of ground faults on the source.  If either or both fault current signals are greater than the corresponding reference current signal, the output is either of one polarity or is not synchronized with the relays so that the registry relay is deenergized and releases to indicate a ground fault condition.
