Title: Process for the switching in of heating stages of a heating plant and a circuit for this purpose
Inventor: DRESCHER BURKHARD
IPC: G05D23/19
Filed: 1983-08-26
Abstract: In a process for switching in at least one further heating stage to a first heating stage, in order to ensure that the instant of switching on of the further heating stage of its own accord matches the respective heating plant, the feed temperature and the return temperature of the heat carrier of the heating plant are measured and cyclically stored anew. The respective measured feed temperature and return temperature are compared with the respective stored temperature value. When both the measured feed temperature and also the measured return temperature are smaller than the respective stored temperature values, the further heating stage is switched on. <IMAGE>

Patent DE-3341479-A1 (DE)
Title: Facing attachment
Inventor: WOZAR ANDREAS
IPC: B23B29/034
Filed: 1983-11-17
Abstract: A working shaft (2) carries a turning head (3) on which a tool slide (7) can be moved transversely to its axis of rotation. The drive for the tool slide (7) is derived from the rotation of the working shaft (2) via a multi-stage epicyclic gear unit. A first stage of the epicyclic gear unit serves as a differential feed gear unit (20, 120) which, by means of a ring gear (28, 128) which can be braked or externally driven, produces a drive speed for the tool slide (7) differing from the speed of the working shaft (2). A secondary feed-reversing gear unit constructed as a two-stage epicyclic gear unit determines the feed direction of the tool slide (7). The drive speed is transmitted via a bevel gear transmission to a spindle drive for the tool slide (7). An automatic reversing mechanism actuated by a torque switch brings about the control change of the feed-reversing gear unit (30). After the advance and return of the tool slide (7), a repeat lock holds the tool-slide drive in a neutral position until the main drive of the working shaft (2) is switched off. <IMAGE>

Abstract: In addition to the filament lamp (4), a monitoring relay (5) is arranged in the housing (2) of the monitoring light (1) in such a way that the monitoring relay (5) and the monitoring light (1) form one constructional unit. The monitoring relay (5) is arranged in the rear part or on the floor of the light housing (2) behind the filament lamp (4) and is connected to two connecting terminals (7, 8). In a flasher system for trailer operation it is connected between the output terminal (11) of the flasher signal generator (12) to the flasher switch (16) and the input terminal (15) of the flasher switch (16) in such a way that when the flasher switch (16) is actuated the current to the flasher lights (18) flows through the winding of the monitoring relay (5) and causes the monitoring light (1) which contains the monitoring relay (5) to light up when the flasher system is functioning correctly. <IMAGE>

Patent DE-3431172-A1 (DE)
Title: Safety binding
Inventor: WALLISCH FRANZ
IPC: A63C9/00
Filed: 1984-08-24
Abstract: This safety binding has the advantage, as compared with conventional safety bindings, that, in deep snow, it prevents with one hundred percent reliability, in the event of the binding being released, the escape and/or loss of the skiis by catching them with twine or wire and, with a combination of the conventional and ancient Ariadne's thread and the red avalanche cord, guarantees that the skiis will be found again, only a few metres of twine and/or wire being needed now and then. The twine catching tension can be greatly reduced in that the thread is guided from the reel, situated above the toe of the boot, initially to the front point of the ski, via an eyelet, and only then to the heel of the boot, as a result of which a spontaneous "Telemark" executed by the unsecured ski distributes the momentum-destroying phase over this turning phase and the catching time is thus greatly increased. Previously stoppered bindings can easily be converted.
Patent DE-3431353-A1 (DE)
Title: Method and apparatus for extending the surface area of an elastic material
Inventor: SCHMOOCK HELMUTH
IPC: C14B1/26
Filed: 1984-08-25
Abstract: The method is used to extend the surface area of a web of leather. The web of leather is stretched together with an elastic backing material, onto which the web of leather has been placed in a coplanar fashion. The elastic backing material is rigidly clamped at its edges. A force which stretches the elastic backing material is imparted to the latter in a region surrounded by the rigid clamping means. The web of leather can be placed with at least one of its surfaces against the elastic backing material or with its two opposite surfaces each being in contact with an elastic backing material. The force may exerted inside or outside a region of the elastic backing material covered by the web of leather. The apparatus for implementing the method uses an elastic backing material which is rigidly clamped at its edges and has at least one point of application for a force which stretches the elastic backing material. The backing material has at least one point of application for a force which stretches the backing material, which point of application may be inside or outside a region covered by the web of leather. At least one web or two webs of the elastic backing material which extend on the same plane may be provided. If two webs are provided, the web of leather is situated between these two webs.

IPC: F24H1/20
Filed: 1985-04-06
Abstract: A heater is proposed for electrically operated hot-water apparatuses, in the case of which apparatuses at least one heating element is immersed in the water which is to be heated. The heater consists of at least one ceramic supporting tube (1) which has on its outer surface a thick-film heating conductor (2) which, for its part, is covered with an insulation layer (5).
