Title: Process for wrapping a coin stack to form a coin roll and wrapping material for forming a coin roll
Inventor: ZIMMERMANN GERT
IPC: B65D85/58
Filed: 1983-02-17
Abstract: For a process for wrapping a coin stack to form a coin roll with a strip of wrapping material, there is provided as wrapping material a strip of adhesive film, the width of which corresponds approximately to half the stack circumference and the length of which corresponds at least to the height of the coin stack. By means of the strip of adhesive film, the coin stack is embedded parallel to its longitudinal axis in the form of a half shell. By means of the strip of adhesive film according to the invention as coin-stack packaging, the mechanical packaging of coin stacks is greatly simplified, at the same time with a considerable saving of material, since there is no longer any need for a rotational movement of the coin stack for packaging purposes, but merely a relative movement in the direction of the longitudinal axis of the coin stack. Furthermore, a considerable saving on material is achieved since the area of the strip of adhesive film amounts to only approximately 20 to 25% of the area of a conventional wrapping material. Moreover, the handling of the finished coin roll becomes considerably easier. In one embodiment of the invention, the coin stack can also be fed transversely to its longitudinal axis to the strip of adhesive film or the latter transversely to the longitudinal axis of the coin stack.

Patent DE-3312054-A1 (DE)
Title: Reversing valve controlling the through-flow of a pressure medium
Inventor: STEIGER ANTON
IPC: F16K31/08
Filed: 1983-04-02
Abstract: Due to different diameters (D, d, s) of the valve seats (14 and 15) and the valve stem (5), the pressure medium produces at the valve body (4) a force which is used as a drive for actuating the valve. The control device (16) can therefore be reduced to a simple holder (only acting passively) without external drive. This holder is released by an electric impulse signal (24, 25). Therefore the signal energy produced and transported in electronic control systems is sufficient for the valve actuation without the necessity of additional drives. <IMAGE>

Title: Displacement machine for compressible media
Inventor: EMMENTHAL KLAUS-DIETER DR ING
IPC: F01C1/02
Filed: 1983-04-12
Abstract: A displacement machine for compressible media has at least one displacement chamber (24, 25) essentially designed in the manner of a helical slot and arranged in a fixed housing and a displacement element (20, 21) also designed essentially with a helical shape, assigned to each displacement chamber and engaging in this, which element as a ribbon-shaped strip is arranged on a disc-shaped rotor (6) eccentrically driven in relation to the housing (2, 3). A drive device (4, 5) providing the eccentric drive engages on at least one point of the rotor and a guide device (12, 13) on at least one further point arranged at an interval from this. In order to significantly reduce the manufacturing cost of such a displacement machine, it is proposed that the displacement chamber (24, 25) be formed by an insert (30) held in the housing, which insert comprises a plastic part positively held in the metal housing (2, 3), which part is manufactured by injection moulding. <IMAGE>

Title: Process for utilising the waste heat of a baking oven
Inventor: HENNIG WERNER
IPC: A21B3/00
Filed: 1983-04-21
Abstract: The invention relates to a process for utilising the waste heat of a baking oven, preferably a continuously loaded baking oven having baking surfaces moving during the baking process, which is equipped with one or more flue gas heaters and in which the baking chamber is indirectly heated by flue gas circulation. The aim of reducing the specific thermal energy consumption by utilisation of the waste heat contained in the flue gases and in the baking atmosphere removed by suction, with simultaneous increase of the thermal efficiency and simultaneous reduction of the use of corrosion-resistant steel, was achieved in that, in a system of heat exchangers, the waste heat of the flue gases removed by suction is utilised in a first heat transfer stage to heat the fresh air to be fed to the baking chamber and is utilised in a further heat transfer stage to generate steam, and in that a further steam generation is carried out by utilising the waste heat of the baking atmosphere removed by suction using the water to be vaporised which is heated in a third heat transfer stage and that the two steam quantities generated are admitted mixed to further use.

Title: Secondary electron multiplier made of metal-coated silicate microsieves
Inventor: BRANDT REINHARD PROF DR
IPC: H01J43/22
Filed: 1983-06-18
Abstract: Microsieves are made by irradiating silicates, for example quartz and mica, with heavy ions and then etching them (DE 2708641 C2). Said microsieves are heat-treated for some time (> 1 min) in an inert, oxidising or reducing atmosphere in the range from 150 DEG C to 900 DEG C and a metal layer is deposited on them in such a way that both surfaces have an electrically conducting layer. This converts a microsieve into a serviceable secondary electron multiplier.
Patent DE-3324011-A1 (DE)
Title: Density monitor for high-voltage switching systems
Inventor: KURUC MOZES
IPC: H01H35/28
Filed: 1983-07-04
Abstract: In order to monitor the gas density in gas spaces, density monitors are used which contain pressure sensors (4) and switches (5) which are operated by said pressure sensors (4) via mechanical transmission means (6) which contain temperature-compensation elements, on reaching specific critical densities. In order to ensure temperature compensation which is accurate, follows temperature fluctuations of the gas quickly and is largely independent of disturbing influences, the temperature compensation elements in the proposed density monitor are arranged such that they are in direct contact with the gas which is to be monitored. At least one pressure sensor (4) is sampled, which projects into a cavity (2) connected to the gas space, consists of bimetallic strips (18) and operates switches (5) via levers which are constructed as metal strips (17). The pressure sensor (4) consists of a bellows (10) which is sealed by a cap (11), a ring (14) which can be displaced axially in order to set the critical density, and a spiral spring (12) which is clamped in between the cap and the ring. The temperature compensation can be matched to the gradient of the density line to be monitored by defining the active length of the bimetallic strip (18), which definition relates to the selection of a suitable attachment point (19) of the bimetallic strip (18) to the metal strip (17). A density monitor preferably contains three monitoring elements which are constructed as described and each of which monitors a specific density line. <IMAGE>

Title: Coupling device between a towing vehicle and a trailer
Inventor: HERMBUSCH GERD DIPL ING
IPC: B60D1/173
Filed: 1984-01-07
Abstract: A coupling device between a towing vehicle and a trailer of a vehicle-trailer combination is given a configuration which ensures a high degree of oscillation stability of the vehicle-trailer combination when travelling fast and when travelling through large bend radii whilst it permits the adjustment to tight bend radii without difficulty when travelling slowly. For this purpose, the coupling device has a four-bar linkage which is constructed as a trapezoidal link and in addition has a connecting link which is arranged on the coupling and the web of the said linkage. The connecting link is blocked in its basic position by means of a locking device which in turn interacts with a control device which is influenced by the link arms of the trapezoidal link or four-bar linkage as soon as the said arms exceed, or undershoot, a predetermined swivel angle region in relation to the web or to the coupling. At this moment, the locking device then disengages and releases the connecting link in order to set a large articulation angle between the longitudinal axis of the towing vehicle and the longitudinal axis of the trailer.

Title: Self-excited, solid-state AC generator
Inventor: KLEIMANN ANDREAS DIPL ING
IPC: H02M7/537
Filed: 1984-05-10
Abstract: The invention relates to a self-excited, solid-state AC generator having a power circuit breaker (2) which supplies rectangular current pulses from a DC voltage source (5) via a relatively large inductor (3) having a freewheeling diode (4). The power circuit breaker (2) is controlled via a feedback circuit which comprises a phase shifter (16) for detecting the tuned-circuit voltage. Since the duration of the current pulse supplied to the power circuit breaker depends on the tuned-circuit voltage, but the phase shifter supplies a frequency-dependent control voltage, a multiplier (17), which is controlled in a frequency-dependent manner, for the output signal of the phase shifter (16) is provided in order to compensate for this frequency dependency. In order to prevent overloading of the power circuit breaker (2) in the switching-on phase, the tuned-circuit voltage is artificially increased in the switching-on phase by a function transmitter so that the tuned circuit reaches the steady state smoothly and with relatively small current pulses. <IMAGE>

Title: Chassis for a wheelchair
Inventor: GEISLER NORBERT
IPC: A61G5/06
Filed: 1984-06-15
Abstract: In order to create a wheelchair which can negotiate steps its chassis (1') is designed as a bottom plate (1) on which the wheelchair seat is rigidly fastened, this bottom plate being equipped with four support posts (11, 11') fitted in the region of their respective corner points and vertically adjustable by a motor, and with posts (2, 2') which are likewise adjustable vertically and serve as a bearing for the wheels (3, 3'). The posts (2, 2') are fastened on the chassis (1') so as to be additionally movable horizontally in the driving direction with respect to the chassis and so as to be movable about their longitudinal axis. All adjustment functions of the support posts (11, 11') and of the posts (2, 2'), as well as the wheels (3, 3') are assigned individually controllable drives which permit stepwise vertical and horizontal displacement of the chassis (1') and hence of the wheelchair, with due consideration of the type and dimensions of the steps, with the interaction of a control unit. A wheelchair equipped with such a chassis (1') thus makes it possible for any user to negotiate steps in a particularly simple manner, the mechanical structural complexity in the chassis region simultaneously being kept low. <IMAGE>
