Title: Home training exercise machine - has preset threshold signal generator, comparator and visual audio warning if effort is below target
Inventor: CHRISTOPEIT HORST
IPC: A63B24/00
Filed: 1980-08-20
Abstract: This home training machine, e.g. bicycle, provides added incentive and interest by simulating a competitor whose performance one would attempt to beat, thus resulting in greater effort. This is achieved by using a threshold signal generator, a comparator and a visual display and audio source which emits a warning signal if the effort is below a pre-set target. Signals generated by a threshold signal generator represent pre-set speed and distance covered. A detector monitors actual effort and produces an analogue signal. The signals are compared in a comparator which is followed by a visual/acoustic warning signal source.

Title: Vehicle seat belt tensioning mechanism - has pressure medium-driven piston connected to belt wind-on spool via cable drive
Inventor: VOIGT WILHELM
IPC: B60R22/46
Filed: 1980-10-29
Abstract: The seat belt retractor is fitted with a tensioning mechanism, which, following a sudden deceleration of the vehicle, absorbs any existing slack of the belt before the blocking action occurs. The mechanism is operated by a piston driven by the gas pressure of a detonated explosive charge fitted in a cylinder containing the piston. The explosive charge is detonated by an electric impulse emitted by a deceleration-sensitive device and the slack of the belt (22) is taken up by the forward moving piston (13) with a deviating roller (21) on its end. The belt is looped around the deviating roller and leads on to wind-on spool (24) which remains stationary while the belt slack is taken up by the device.

Patent DE-3100089-A1 (DE)
Title: Heating water tipping grate
Inventor: COLLET WERNER
IPC: F24B1/183
Filed: 1981-01-03
Abstract: Open fireplaces were in the past assigned the purpose of a cosy living atmosphere. Today, thought is given to improving the degree of efficiency of open fireplaces. Known devices for heat recovery extract the heat energy outside the fire region. The temperatures here are so low that economical utilisation is not guaranteed. Furthermore, these fireplace installations either have to be installed in a new construction or with a great amount of rebuilding and costs. Additionally, there is the disadvantage that the fireplaces are difficult to clean and cause odours. The problem is solved in that, in the fireplace, a pipe coil is laid, which is connected to the water circuit of the house heating installation and thus draws to a great extent heat from the fireplace fire and supplies it to the house heating installation. Pipe coil and frame form a unit, as a result of which no rebuilding measures are necessary on the fireplace. Bearings make possible the tipping up of the pipe coil and thus ease cleaning of the fireplace. Possibilities for use: in all open fireplaces and other fireplaces.

Title: Stereoselective (regioselective) preparation of alpha - and beta -naphthol
IPC: C07C39/14
Filed: 1981-01-24
Abstract: Process for the selective preparation of  alpha - or  beta -naphthol by catalysed acid hydroxylation (Lewis or Bronstedt or superacidic mixtures thereof) of naphthalene by hydrogen peroxide. Conventional acid systems (not superacidic), such as e.g. hydrogen fluoride, pyridine-hydrogen fluoride complexes (i.e. pyridine polyhydrogen fluoride), dry aluminium fluoride etc. afford a stereoselectivity of alpha -naphthol with an isomeric purity of between 92 and 98 %. The use of superacidic systems such as fluorosulphuric acid, fluorosulphuric acid-antimony pentafluoride, hydrogen fluoride-boron trifluoride, hydrogen fluoride-antimony pentafluoride, hydrogen fluoride-tantalum pentafluoride etc. lead, however, to the formation of  beta -naphthol with an isomeric purity of between 92 and 98 %.

Title: Read-write memory module with contactless data transmission and contactless power supply
Inventor: TOMOV ANTON
IPC: G11C8/00
Filed: 1981-05-27
Abstract: The invention relates to an electronic, non-volatile read-write memory module with a contactless serial interface and the capability of addressing each individual byte directly. Data transmission takes place by means of IR light. If total electrical isolation is desired, power may be supplied contactlessly. The memory module is an independent three-dimensional unit of handy dimensions and relatively large storage capacity (for example 32 kbytes). This storage medium can be used advantageously wherever a transportable data memory is required and other storage media are ruled out for reasons of ambient conditions (temperature, vibration, dust etc.) or else owing to the space available. A simple adaptor makes it possible to achieve a standard V.24 interface and, as a result, compatibility with most computers. Figure 1 shows the block diagram and Figure 2 a sketch of an already implemented design for a storage capacity of 24 kbytes. <IMAGE>
