Abstract: Coupling miniature liquid fueled fuel cells with portable electrical devices, with or without rechargeable batteries, lead to new appliance configurations: charging holster, piggyback charger, fuel cell integral with rechargeable battery, fuel cell with voltage regulating electronics, supplying fuel through a tube with a valve or pump, and supplying power though an electric cable between the fuel cell and the electronic device and the fuel cell power pack having independent communication and functions from the portable electrical devices. In all of these configurations there may be a window showing the fuel level of a disposable fuel ampoule or refillable fuel tank. Fuel is distributed through disposable fuel ampoules in blister packages, or refueling bottles. Adjustable moisture and thermal internal insulation allows fuel cells to run at elevated temperatures. These design features permit greater performance, workability, and convenience to the user of these portable electronics.

Abstract: The present invention is a one-step thermal method for analyzing the acid-base content of earth samples, specifically mine overburden samples. By using a low oxygen concentration, preferably about 3%, the transition metal carbonates in the sample decomposed to produce carbon dioxide at a lower temperature than the alkaline earth metal carbonates. In contrast, alkaline earth metal carbonates decompose at approximately the same (higher) temperature regardless of the oxygen concentration. Any oxidizable sulfur forms present in the sample are also oxidized by using this oxygen concentration so that only one experiment is required to obtain the carbonate and sulfur contents of the sample.

Abstract: The syringe is provided with a needle-covering sleeve (14), which is slidably fitted on the syringe barrel (1) and is held in its retracted rest position by means of retaining tongues (10), which hook its rear rim (13). At the end of the injection stroke of the plunger (2), a rear head (8) of the stem (3) of the plunger (2) radially opens the retaining tongues (10) apart, which release thereby the needle-covering sleeve (14). Then, the latter is axially advanced by a spring (16), until it entirely covers the needle (5). The needle-carrier (4, 104) has at least one lateral locking projection (28), slidably engaging in a longitudinal slot (18), which is formed in the needle-covering sleeve (14) and is delimited at its sides, at least in its progressively tapering rear end (118), by two convergent and elastically openable stop sticks (19) which allow the passage of the locking projection (28) between their free ends, but then point against it and fasten it to the needle-covering sleeve.

Abstract: A hi-hat (1) is used as an instrument, especially as a percussion instrument. The inventive hi-hat consists of a set of in total three or more cymbals (2, 3, 4). An upper mobile cymbal (2) and a lower, also mobile cymbal (4) are struck against the middle, stationary cymbal (4) by means of a common operating device (5), in order to produce a noise. The movement of the pedal (31) is reversed by means of either an appropriate pneumatic arrangement with a piston (8) and corresponding cylinder chambers (10, 23) or a mechanical device which diverts the pedal movement via a cable (50) and a deflection pulley (51) so that the outer tube (14) moves upwards against the middle cymbal (3) whilst the rod (7) is pulled downwards in the opposite direction, hereby causing the upper cymbal (2) to strike the middle cymbal (3).

Abstract: A hi-hat 1 has available an operating unit 1 with the aid of which the upper cymbal dish 2 as well as the lower cymbal dish 4 can be moved. The upper cymbal dish 2 is for this reason allocated to a rod 7 which can, as is well known, be moved downward in relation to the lower cymbal dish 4 through the foot pedal 12. At the same time, the motion of the foot pedal 12 is guided through a cable line 13 and a guide pulley 14 such that a sheath tube 10 which bears the lower cymbal dish 4, is moved in the reversed direction, that is here upward, through appropriate connections. cylindrical springs 24, 25 and further safeties guarantee that overloading of the parts cannot occur.

Abstract: A switch cabinet is provided for protection of servers and other highly sensitive computer devices or miscellaneous equipment. The cabinet is configured as a protection cabinet with an interior isolated from the atmosphere. The interior is continuously provided with fresh air by a ventilator. Fresh air is controlled by early detection fire sensors shortly before passing through the ventilator. When fire breaks out, the early detection fire sensors activate gas bottles filled with the noble gas argon, so that argon can be introduced into the interior to extinguish the fire once fresh air supply has been stopped, thereby ensuring early and fast extinguishing of the blaze.

A silicone cock (4) of an elastic material, through which coated electric heating wires (2) of the hot-water tube are placed, is inserted into the cylinder-like concave (3b) of the plug (3). A crown nut (5) is screwed onto the plug (3), pressing the cock (4) to enhance the water-tightness of the end portion of the hot-water tube and to allow the electric heating wires to be placed effectively from inside to the outside of the hot-water tube.

Abstract: For purifying dust-containing air, particularly in underground mining and tunnel construction, a dust separator 1 in the form of a rotary washer 1 is proposed. The drive 5 of said rotary washer 1 is equipped with a gear unit 10 in order to enable long-term operation with a straight characteristic. Furthermore, disposed downstream of the fan impeller 6 is a special separating element 11 in the form of a demister 20, which is disposed so as to be suspended approximately horizontally in the air stream. Clogging of the demister 20 is therefore effectively prevented and so uniform and reliable operation is guaranteed. The demister 20 together with its associated jetwashing device 22 may be swivelled by a positioning motor 23 into an, in each case, optimum position.

Abstract: Profiled sections 1, in particular extruded seals made of elastic material, are designed and produced economically such that they have absolute storage stability and low coefficients of friction and are suitable for a wide variety of uses. The profiled sections 1 are made of a non-lacquer-repelling material. After leaving the extruder 12 and before entering the fused salt bath 16 the profiled sections are coated with a lubricating lacquer 7 applied to the uncured surface 5. The lubricating lacquer 7 is then cured in the fused salt bath 16 without there being a need for a separate curing section or similar. This method not only evenly coats the profiled sections with lubricating lacquer 7 but also prevents the formation of air bubbles or the like, thereby yielding a consistently even coating 6.

Abstract: The present invention is a match filter architecture that is used in the Spread ALOHA Multiple Access (SAMA) receiver to facilitate the separation of individual user's data from the incoming SAMA sample “chip” stream. The filter outputs the convolution of the incoming signals with the matched filter impulse response at the same rate as the sampling of incoming chips, thus providing a means to detect more than one user within one match pattern interval. The filter operates completely synchronously with a high frequency filter clock, which is used to generate the sample clock. Incoming chip samples are loaded in the delay shift register at the sample clock rate. The samples are shifted at the filter clock frequency. Each bit in the chip trickles down through serial adders, with one clock period of delay for each serial adder. At the final accumulator, the serial sum bits are collected for parallel presentation to output registers at the sampling frequency.

Abstract: A selection system for pile yarns in a gripper Axminster weaving machine has a gripper associated with an elongated pile yarn carrier, and provided to position a number of yarn ends at mutual distance in the length direction of that carrier. Each pile yarn carrier is axially movable in its length direction to present a selected yarn to an associated gripper. A movable selection beam effects the axial movement of the pile yarn carriers, coordinated with the movement of the grippers, by protrusions and notches working together on the pile yarn carriers and on the selection beam. The engagement into each other of the aforesaid protrusions and notches can be selectively controlled in function of the yarns to be selected, in which the pile yarn carriers are predominantly horizontally disposed. The selection beam positively drives the pile yarn carriers in horizontal direction both in forward and in return movement.

Abstract: A can end is punched from a sheet of material, formed and curled in a single station with a single movement of the punch. An intermediate axial peripheral wall is formed by the blanking punch and a cooperating die core ring. A pressure sleeve surrounding the die core ring has a chamfered inner edge which engages a peripheral edge of the blank at the lower end of the axial peripheral wall. While the formed end is held between the punch and the die, the pressure sleeve moves upward, forcing the peripheral wall outward into a recess, either in the blank punch or the die pressure sleeve, moving the metal outward into the curl. The curl is thus expansion formed rather than compression formed. The formed and curled end is removed from the assemblies by knockout rings.

Abstract: A bottle decasing, breaking and separating system and method has a hopper feeder for receiving bottles and cases. The bottles and cases are supplied to a trommel by a conveyor beneath the feeder. A conveyor communicating with the trommel receives the separated and fragmented material. A chute connected to the conveyor transports the fragmented material. Lifting tubes in the trommel are for lifting, tipping and tumbling the cases and the bottles in the trommel when it rotates. Strong screens in the trommel fragment and remove the bottles tumbling in the trommel. The cases remain at upper levels above the fragmented material in the trommel. The trommel may be a drum which slopes downward and rearward from the forward to the rearward ends. A trough below the trommel receives the fragmented material from the trommel and supplies the material to a conveyor. An extension communicating with the conveyor for supplies the fragmented material from the conveyor to recycling bins.
