Abstract: A first photographic image 1, in the form of a hologram of the tooth 2 and of fixing points 3 located close to the tooth in a first evaluation, is arranged next to a second photographic image 4', in the form of a hologram of the tooth 2' and of fixing points 3' located close to the tooth in a second evaluation. Adjustment members 5, 6, 7 are provided in order to permit a relative displacement of the first photographic image 1 relative to the second photographic image 4'. This brings the fixing points 3 in the first photographic image to correspond with the fixing points 3' in the second photographic image 4', after which the displacement of the tooth 2 can be evaluated as a discrepancy between the position of the tooth in the first photographic image 1 and the position of the tooth in the second photographic image 4'. A model can be used instead of the second photographic image. <IMAGE>

Abstract: The heat pump system comprises a pipe circuit for heat exchange with the earth. On a time basis, the heat pump takes its heat from the building output air, and out of the ground, and/or from both sources simultaneously. - The heat pump evaporator is coupled via a pipe system to a cooling battery in the form of a fluid/air heat exchanger in the output air channel, and to a ground heat collector. Maximum energy can be recovered from the output air without the cooling battery forming frost, with the heat-carrying medium absorbing heat from the earth. The system also permits heat to be fed back to the earth which can be used as a heat store.

Abstract: Flame monitoring devices with thermocouples are used in stationary and mobile burners that are fired with liquid or gaseous fuels. They signal the presence of the flame, and trigger switching processes as a function of the signal. The invention is intended to provide a rugged monitoring device that can be manufactured easily, and amplifies the thermoelectric e.m.f. without faults or bounce, and reliably over a wide temperature range, so that drivers can be switched. The object is achieved according to the invention by having the thermoelectric e.m.f. of a thermocouple generate an electromagnetic field in a coil with an iron core, which can be constructed as an open or closed magnetic circuit. There is a Hall-effect circuit in the air gap of the iron core, which is activated by the lines of flux of the electromagnetic field. If the Hall-effect circuit, which is supplied with an internal operating voltage, reaches its operating value due to the induction density, its output signal switches drivers for switching the ignition, fuel and air supplies on or off. <IMAGE>

Abstract: The invention relates to a device for rapid positioning of a heavy trolley 301. The trolley 301 is finely positioned by means of a fixed positioning rod, for example a gear rack 302, and an interacting rotary element, such as a gearwheel 305, which latter is driven by a motor fixed to the trolley 301. The trolley 301 is rapidly and crudely displaced by means of a further member, this further member being able to be constituted by one more gearwheel 401, which interacts with the gear rack 302 and is driven by a separate motor fixed to the trolley 301. This further member additionally supplies a certain force in the final positioning by means of the gearwheel 305, so that the play between the gearwheel 305 and the gear rack 303 is eliminated by pretensioning. Instead of a second gearwheel 401, a toothed belt or a pneumatic cylinder can be used. <IMAGE>

Abstract: The invention is directed to a brake band for bringing the saw chain of a chain saw to standstill. Chain saws include safety devices which bring the saw chain to standstill by applying a brake band to a brake drum. These safety devices effect numerous applications of the brake band to the brake drum so that the brake drum wears rapidly and has only a short service life. The brake band of the invention has a friction side which is provided with a layer made of an oxide ceramic which increases the service life for very short braking times even when oil penetrates the region between the brake band and the brake drum.

Abstract: The starting of an i.c. engine usually takes place by carrying out the necessary number of starting attempts with the carburetor choked in order to obtain an ignition. After that, the choke valve (15,23,24) is opened and the engine can be started by making more starting attempts. Thus, the engine does not continue to run when the choke is on. In order to simplify the starting procedure of e.g. a chain saw, the carburetor can be provided with an elastic choke valve. The elastic valve makes the engine start even though the choke valve is closed as the choke valve will yield to the air stream (FIG. 1) and furnish fuel air mixture to the engine. With the engine running, the choke valve can then be opened.

Abstract: A hydraulic dual-circuit brake system with anti-skid braking (ABS) and traction control (ASR) for motor vehicles having control valve assemblies, each control valve assigned to one wheel brake cylinder of a vehicle wheel for feeding a wheel-slip-dependent brake pressure, and includes one return pump with two separate pump elements for each brake circuit. For supplying brake pressure in traction control, a precharge pump and a valve unit are provided. In the traction control mode the precharge pump feeds brake fluid from a brake fluid tank into the pump element associated with the brake circuit of the driven wheels while the valve unit disconnects the pump element from the master brake cylinder and connects it to the brake fluid tank via a pressure limiting valve. A check valve prevents brake fluid from flowing into the ABS brake circuit during this process via the pressure limiting valve. The air bubbles created upon expansion of the brake fluid at the pressure limiting valve reach the brake fluid tank along with any excess brake fluid and thus are kept away from the master brake cylinder.
