Title: Device for the installation of pipes for house service connections in cellar walls, foundations and the like
Inventor: JESCHKE IMMANUEL
IPC: F16L5/06
Filed: 1981-02-23
Abstract: The object to be achieved is that of providing a device by means of which pipes for house service connections can be installed easily and reliably, such that they are sealed with respect to moisture, into the through-passages of cellar walls, foundations and the like. The invention achieves this object in that it has two pairs of disc-shaped half-shells which have a central cutout, can be assembled in pairs and at least one half-shell of which has an attachment with a filling stub. A sealant produced on the basis of cement, asphalt or plastic can then be filled into the filling stub of this device and so into the through-passage, the device remaining fixed on the pipe until the composition has become stable by hardening and, on removal of the disc-shaped half-shells, movement of the composition no longer takes place.

Title: Rate-related tachycardia control pacemaker
Inventor: SPURRELL ROWORTH A J
IPC: A61N1/362
Filed: 1981-03-11
Abstract: There is provided an improved pacemaker for the control of tachycardia. After confirmation of the occurrence of tachycardia a burst of at least three stimulating pulses is generated. The time intervals between successive pulses decrease by a fixed decrement, and thus the pulse rate during each working cycle increases and the burst can be characterised more accurately as "tweet". The first pulse is generated after the last heart beat used for confirmation of the occurrence of tachycardia, specifically at a point in time which depends on the rate of heart beats in the tachycardia. The time delay between the last heart beat and the first pulse in the tweet is equal to the time interval between the last two heart beats minus the constant decrement which characterised the successive time intervals between the stimulating pulses. Since successive pulses are generated at an increasing rate and since the first pulse is generated at a point in time which depends on the tachycardia it is more likely that the tachycardia will be terminated.

Patent DE-3119604-A1 (DE)
Title: Flexible tank separation
Inventor: VETTER KLAUS
IPC: B08B3/04
Filed: 1981-05-16
Abstract: In cleaning machines having a plurality of cleaning chambers operating independently of one another, a flexible splash-protecting means prevents washing liquid of one cleaning chamber getting into the neighbouring cleaning chamber. By incorporating a stabilising weight in a splash-protecting curtain, and by coordinating the relative dimensions of the through-opening, the length of the curtain and the suspension axis, as well as by arranging a second splash-protecting curtain, washing liquid is prevented from passing between chambers even while articles to be cleaned are running through.
Patent DE-3120118-A1 (DE)
Title: Water heater and use of the same in a heating installation
Inventor: SCHMID PAUL
IPC: F24D11/02
Filed: 1981-05-20
Abstract: The water heater consists essentially of a service-water storage tank (10) and a heating-water storage tank (11). The service-water storage tank (10) is arranged partially in the heating-water storage tank (11). The heating of the heating liquid in the heating-water storage tank (11) takes place via one or more heat sources (16, 17, 18) which draw the heating liquid from the heating-water tank (11) at different levels and deliver it again to the heating-water storage tank (11) at a raised temperature so that a temperature layering is created in the heating-water storage tank (11). The service water in the service-water storage tank (10) is consequently heated after the heat exchanger operation. <IMAGE>
Patent DE-3124323-A1 (DE)
Title: Momentary-contact limit switch
Inventor: HERMLE ROLF DIPL KFM
IPC: H01H3/62
Filed: 1981-06-20
Abstract: In the case of a momentary-contact limit switch having a housing which has at least one hole for guiding a plunger by means of which a switch which is accommodated in the housing is operated, the DU socket (which is normally inserted into the guide hole and relatively expensive) can be replaced by coating at least the wall of the guide hole, but preferably the entire surface of the housing, with a fluorinated hydrocarbon resin, using the sintering process. The sliding coating (layer) thus created is intended to have a thickness of 10-20  mu m. Since, in contrast to the normally used DU sockets, it is possible to drill through such a sliding coating directly at an angle, the housing furthermore has a hole to secure the plunger in rotation, which hole passes through the guide hole and into which a securing pin is inserted, which runs transversely with respect to the plunger axis. Said securing pin interacts with a flat on the circumference of the plunger.

Filed: 1981-06-25
Abstract: A surface treatment process and a surface treatment device for the dry treatment of surfaces is given, cations and anions being produced separately from one another and being transported to the substrate via paths which are likewise separate from one another and applied together to a single substrate. Harmful actions as a result of space charge effects are avoided, such that the effectiveness of the treatment is substantially improved. Small accelerations of the ions are used, and the ion beams transport a comparatively large current.
Patent DE-3133334-A1 (DE)
Title: Gear for lens covers (lids, caps) on photographic cameras
Inventor: BELITZ FRITZ DR
IPC: G03B17/04
Filed: 1981-08-22
Abstract: A gear for hinged lens covers on photographic cameras is described, which consists of a four-bar linkage having a crank which is connected to the hinged cover, as well as a driven rocker, which is connected to the lens, and of a connecting rod (connecting link, coupler), which connects the crank and the rocker to one another. At least one of the links between the connecting rod and the crank or the rocker is constructed in the manner of a sliding link such that the connecting rod and the crank or the rocker change their length in a mutually complementary manner during the hinged movement of the cover. The result is, on the one hand, that the cover is prevented from striking against the lens mount, and on the other hand that a more favourable characteristic of the required force is achieved, which is only slight at the start and end of the hinging movement, while a somewhat higher force is required only approximately in the middle of the movement, where the force can be effectively applied by the user.
