Title: Reflection bead coating of concrete parts of DIN 483 and non-standardised concrete parts in road and traffic engineering, having highly light-refracting glass beads having a refractive index of approximately 1.9, by means of a white concrete protective coating in accordance with VOB/C DIN 18363 2.4.6 based on liquid potassium silicate
Inventor: SCHAEFER REINHOLD HUGO
IPC: E01F9/506
Filed: 1984-05-23
Abstract: The concrete protective coating here should be applied in accordance with the manufacturer's instructions as a support layer which causes silicification between the substrate and the reflection beads which are embedded up to half of their mean size by means of compressed air. A general chemical formula for the silicification reaction cannot be given, since this is taken to mean the totality of a plurality of different chemical reactions based on the polycondensation of the silicate anions to give water-insoluble silicic acid, and on chemical reactions of the potassium silicate with components of the substrate and of the coating glass. This chemically bonded unit is perfectly matched to the substrate with respect to expansion and emission protection, and has good processing properties and is environmentally friendly.

Title: Operating procedure for a bivalent heating plant
Inventor: BAUMGAERTNER MANFRED DR
IPC: F24D19/10
Filed: 1984-08-09
Abstract: The invention relates to an operating procedure for a bivalent heating plant having a heat pump and a heating boiler, the heat pump being controlled as a function of the heat requirement. The heating boiler is switched on upon fulfilment of a release condition dependent on ambient temperature. The boiler is switched to standby mode when the release condition vanishes and is not completely switched off again until no further release condition is present for a time interval of  DELTA t > 24 hours. This prevents the heating boiler from being switched on and off in the event of day/night fluctuations in ambient temperature and thus from being exposed to substantial corrosive loads. <IMAGE>

Title: Repeater rifle, especially as a sporting rifle, such as for biathlon
Inventor: FORTNER JUN PETER
IPC: F41A3/48
Filed: 1984-09-05
Abstract: A repeater rifle, especially as a sporting weapon such as for biathlon competitions, for example, comprises a breech housing (1), a breech body (5) which is connected thereto, and a control element (21), which is arranged in the breech and can be displaced in a relative manner via a cocking lever (27). In order for sporting purposes to make it possible to retract the slide of the rifle by means of the cocking lever, merely by displacement in the axial direction, the intention being to reduce the movement which has to be carried out by the hand to a minimum, it is provided that the cocking lever (27), which is mounted on the control element (21) can be displaced forwards and backwards only in the axial direction and at the same time projects through an axial elongated hole (29) in the breech body (5), the length of which hole corresponds at least to the maximum displacement movement of the control element (21) relative to the breech body (5) for unlocking and locking. Furthermore, the axially displaceable control element (21) projects beyond the rear end of the breech housing (1) and ends in a thumb rest (23) at the end. Since the control element itself is fitted such that it can be tilted, a lever effect is additionally produced, as a result of which the forces which are required at the start of the repeating process are reduced. <IMAGE>

Title: Play-free bearing arrangement for a pivoted part driven in an oscillating manner
Inventor: OBERMAYER HEINZ
IPC: F16C19/55
Filed: 1985-09-18
Abstract: A pivoted part driven in an oscillating manner and designed as a drum (4 or 4') is mounted at both ends in first rolling bearings (5 or 5'). Each of these first rolling bearings has assigned to it a second rolling bearing (6 or 6') in such a way that the bearing races (52 and 52' respectively) of the first rolling bearings, which races can be rotated relative to the drum, are rigidly connected to one of the bearing races (61 or 62') of the second rolling bearings, the other bearing races of which are fixed to a stationary element (1 or 14) of the bearing arrangement. A driving element (8 or 15) is provided, this being coupled to the interconnected bearing races and imposing on them an additional pivoting movement which is superimposed on the movements of the drum without a reactive effect. Due to this superposition, fixed pairings of elements of the bearings are avoided even in the case of oscillating movements, and an increased wear resistance of the bearing arrangement is thus achieved. <IMAGE>
