Title: Ink-ribbon cartridge with reloadable ink-ribbon spools
Inventor: LANGE HEINZ
IPC: B41J31/10
Filed: 1987-02-18
Abstract: Ink-ribbon cartridges for typewriters or office machines of similar type are subject to different design requirements, the intention being, above all, for them to be easily exchangeable by means of one-handed operation. Since the transporting elements, for example for the carbon ribbon, in cartridges of this type are also mounted in the housing, these cartridges are very expensive. In order to avoid this, ink-ribbon cartridges with exchangeable ink-ribbon spools have been disclosed. The invention is now based on the object of providing an ink-ribbon cartridge with reloadable ink-ribbon spools, which permits a simple and reliable exchange of the ink-ribbon spools and permits simple attachment of the ink ribbon to the winding core (85). This is achieved in that the receiving spool (15) is mounted with a bearing bore (117) so as to be rotatable about a bearing journal (14) and with a bearing surface (118) on a resting surface (81) which is arranged snugly below the receiving bore (86) for the attachment element (92). As a result of this and by means of further developments, the threading-in and attachment of the ink ribbon (29) on the winding core (85) are greatly facilitated. <IMAGE>

Title: Light-gauge sheet welding process and apparatus for carrying it out
Inventor: POGREBISKIJ DAVID MOISEEVIC
IPC: B23K33/00
Filed: 1987-03-12
Abstract: What has been proposed is a light-gauge sheet welding process, according to which, first of all, the joining together of the edges (1, 2), preferably by double-flanged butt joint with a gap of 35 to 250% of the thickness of the edges (1, 2), is carried out, and then the fusion welding of separate drops (8, 9) of the liquid metal, which form at the edges (1, 2), to form a common drop (10), thereby ensuring a gradual transition from edge (1) to edge (2) in the seam root (5). The flash welding can be carried out by means of current pulses, in that the current is increased initially to a value at which the edges (1, 2) melt during a time which is required for a partial flashing off of the actual edges (1, 2), the termination of growth and contact between two separate drops (8, 9), whereupon it is reduced to 5 to 95% of the current value obtained, for a time which is necessary for the melting of the drops (8, 9) to form a common drop (10), and is then increased once again to a value exceeding the first maximum current by 1.1 to 4 times, for a time which is necessary in order to obtain a predetermined penetration depth (H). An apparatus for carrying out the process has also been proposed. <IMAGE>

Title: Positive-displacement pump with oscillating displacers
Inventor: HOFMANN FRANK DIPL ING
IPC: F04B9/04
Filed: 1987-03-25
Abstract: The invention concerns a positive-displacement pump in which the displacers are non-positively connected to the pump drive by means of a rigid linkage during the discharge stroke, while during the intake stroke the displacers are restored by means of an auxiliary force. Its purpose is to subject the course of motion and acceleration of the displacer until the desired permissible negative pressure has been reached to the pump drive with simple means during the intake stroke, in systems where the displacers are non-positively connected to the pump drive, and to adapt the maximum suction force to the desired permissible negative pressure easily. The invention proposes that a gas or liquid under pressure be used as the auxiliary force for restoring the displacer(s) during the intake stroke, one whose pressure can preferably be set and altered throughout the entire intake stroke. <IMAGE>

Title: Device for controlling the charge of a four-stroke internal combustion engine
Inventor: ROTH WILLI
IPC: F02N19/00
Filed: 1987-09-29
Abstract: A device for controlling the charge of a four-stroke internal combustion engine with fuel injection is created in which, in the inlet port, at an appropriate distance upstream of at least one inlet valve of the engine, control diaphragms composed of elastically resilient, lamellar elements are provided, completely sealing off the cross-section of the inlet port. With the control diaphragms closed, two chambers, a first and a second chamber of different volumes, separated from one another, that is a preceding volume with enriched air and a scavenged volume with unenriched air, are thus created in the inlet port. This means that, at the start of the actual charge or intake stroke, during which the inlet valve is already opened but the exhaust valve is not yet completely closed, a not inconsiderable part of the unenriched air is first sucked out from the scavenged volume into the exhaust port. This on the one hand prevents the heavily enriched air, otherwise drawn by this route into the exhaust port, from being able to damage the exhaust system, especially a catalytic converter system, or render it unusable and, on the other, since no enriched air is drawn in, achieves a considerable fuel saving far in excess of 10% and at the same time an associated power increase.

Title: Expansion dowel for anchoring in bores which are produced such that they widen conically inwards
Inventor: FISCHER ARTUR PROF DR
IPC: F16B13/00
Filed: 1988-02-11
Abstract: For bores which are widened conically inwards, use can be made of expansion dowels which have an expansion cone which is positioned on the base of the bore and onto which an expansion sleeve can be pushed. Consequently, a positively locking connection between expansion dowel and the masonrywork is obtained. The expansion dowel is pushed on according to the invention in that the fastening part projecting out of the bore is turned by means of a screwdriver or the like, this ensuring that the expansion cone, which is connected to the fastening part via a thread, does not turn as well. This results in very simple mounting and, by using threaded bolts of different lengths, adaptation to different clamping lengths of the objects which are to be fastened can be achieved.

Title: Electrical switching apparatus
Inventor: SCHLEDORN GERARD
IPC: H01H11/00
Filed: 1988-05-11
Abstract: Known electrical switching apparatuses have a switching apparatus base as well as manual operating elements which can be placed or plugged thereon and are used as rocker or toggle elements for acting on the contact point in the switching apparatus base. In this case, a disturbing effect is that the toggle or rocker elements project out of the plane of the mounting surface. A novel manual operating element for an electrical switching apparatus having a switching apparatus base, which element is guided in the base, converts the translational movement, which is carried out by pressing the control surface of the manual operating element (10, 11) down onto the switching apparatus base (10), into a tilting movement by means of a pivoted lever (30), and moves back into its original position, parallel to the mounting surface, by resetting by means of a resetting spring (42). The novel manual operating element is provided for decorative service switching apparatuses for indoor equipment. <IMAGE>

Title: Chassis for roof cooling units for electronics cabinets
Inventor: SCHWENK MARTIN ING GRAD
IPC: H05K7/20
Filed: 1988-07-01
Abstract: In order to dissipate the heat produced by electronic components installed in electronics cabinets, cooling units are required which are advantageously arranged on the cabinet roof. The installation of the various parts of the cooling unit necessitates complicated shaping of the chassis, and thus costly production from a large number of individual parts. The heat insulation between the air circuit to be maintained in the electronics cabinet and the external air flow, which emits the heat to the environment, results in particular problems in this case. The proposed chassis consists of a self-supporting upper shell 1, which is produced from a thermally insulating material, and of a like lower shell 2 which is inserted into the upper shell 1 such that it fits. In the assembled state, the upper shell 1 and the lower shell 2 jointly form the inner air guide 6 and the receptacle 12 for the evaporator, the upper shell 1 carries the attachments 15 for the parts of the cooling unit, and the lower shell 2 has an insertion opening 24 for the fan as well as a collecting basin 22 and grooves 26 for the condensed water. The described chassis is used for the construction of roof ventilation units for electronics cabinets of any type. <IMAGE>

Abstract: The silencer has a pot-like housing (2) with a connection pipe (5). Two identically formed perforated discs (13), laterally inverted in relation to one another, are integrated in the housing (2) so that their disc areas (17) are located at a distance from one another. The disc areas (17) are penetrated by a large number of perforations (18) of small cross section and a few perforations (19) of large cross section. The perforations (19) of large cross section ensure that, even if some of the perforations (18) of small cross section become clogged, an adequately large exhaust cross section through the silencer is maintained. If the air flowing through the silencer is only slightly polluted, a damping element which is penetrated by micro air ducts can be inserted between the disc areas (17) of the two perforated discs (13), thereby intensifying the damping effect. In addition, the outside of the perforated disc (13) remote from the connection pipe (5) may be covered by a flexibly removable disc. <IMAGE>
