IPC: A63D5/04
Filed: 1980-10-17
Abstract: Microprocessor reflected light monitoring equipment to determine the travel path of a bowl down a bowling alley according to the way it hits the alley after leaving the hand. The monitoring equipment (32,33) contains lamps (11,12,13) and reflectors (14,15,16) and is located either side of the alley (25) at the point where balls (21,24) land in order to progress towards the nine pins (1 to 9 at 10).

Patent DE-3119579-A1 (DE)
Title: Tapping fitting
Inventor: MZYK KLAUS ING GRAD
IPC: F16L41/06
Filed: 1981-05-16
Abstract: The invention relates to a tapping fitting for a pipeline which is under pressure and serves to convey a gas or a liquid. Tapping fittings of the known construction type have the disadvantage of a comparatively complicated and large-volume attachment housing. Moreover, it is necessary, in the case of said known tapping fittings, for the valve disc to be pressed specifically onto the valve seat, because the pressurised medium in the pipeline permanently acts on the valve disc in the opening direction and is consequently always trying to raise the valve disc from the valve-seat surface. These facts can result in leakages in the tapping fitting if the play, present in the fitting gear mechanism as natural tolerance range, has an effect owing to vibrations in the ground. In the context of the invention, it is provided that the pressure in the pipeline (1) also acts on the valve disc (19) with the effect of sealing. For this purpose, the valve disc (10), which can be pivoted by a spindle (36), is suspended, only a small pivot angle existing between the open position and the closed position. Tolerances in the pivot gear mechanism (30, 33, 36) have no influence on the sealing function in the event of vibrations in the ground. Rather, they assist the sealing properties since, as a result of these tolerances, the valve disc (19) can fit, under the influence of the pressure of the medium in the pipeline (1), even more closely on the inclined valve seat (26). <IMAGE>

Title: Locking device for ammunition
Inventor: REHMANN ROBERT
IPC: F42C15/44
Filed: 1981-11-12
Abstract: During the movement of the priming-cap carrier, especially during the rotation of the rotor (6 in Figure 1) in the safe projectile, from the position of rest into the armed position, a locking device (blocking device 2) is cut in, and when the retardation is absent or when the firing acceleration is too low and consequently when the retardation is too little, this permanently blocks (locks) the rotation of the rotor (6) before its armed position is reached. This prevents the possibility that the rotor (6) will assume the armed position even when in the position of rest, for example during the storage of the projectile, or in the case of firing accelerations which are too low, and therefore that premature ignition will be triggered. <IMAGE>

Title: Concrete composition for a masonry unit
Inventor: ROLLMANN JOHANN WILHELM
IPC: C04B28/04
Filed: 1982-02-06
Abstract: Concrete mix for light-weight concrete for producing masonry units. Modern house walls for healthy living must, in addition to statically required strength values, also meet a number of demands based on structural physics. The most important of these are heat protection - which means not only heat insulation - and sound insulation. Nowadays usual wall-building materials are as a rule not able to meet these demands simultaneously, since they are in part mutually exclusive if the most favourable highest values are desired for each. In the light-weight concrete mix according to the invention, aggregates of natural origin but different type and in different grain sizes are combined purposefully and controllably in such a way that the static and physical demands of masonry units produced from this concrete mix are largely met simultaneously. The masonry units produced from the light-weight concrete according to the invention are marketed under the description Romey-Phonotherm all-purpose bricks.

Title: Process for setting a predetermined gas atmosphere in a container loaded with a material and closed by a cover and container for carrying out the process
Inventor: BIENEK HEINZ ING GRAD
IPC: G21F5/008
Filed: 1982-02-09
Abstract: The invention relates to a process for setting a predetermined gas atmosphere in a container loaded with a material and closed by a cover and to a container for carrying out the process. In order to save working gas and make it easier to set the desired atmosphere, according to the invention at least a part volume of the container is filled with a working gas which is under a predetermined pressure, the part volume is temporarily sealed off relative to the ambient atmosphere, the temporary sealing off is cancelled as a result of the introduction of the material to be stored, and the container is closed immediately after the conclusion of the introduction of the material to be stored. The temporary sealing off is ensured either by a foil (3) or by displaceable covers held securely in a temporary closed position. <IMAGE>

Abstract: A composite girder (1) for joists and ceiling beams is specified, which contains a rolled section (2) or a section welded together from plates (8, 9), the flange of which section can be strengthened with additionally welded-on boom plates (7). Head bolts (6) are provided at the upper web end (5) for subsequent connection to a ceiling. This arrangement is encased, at the factory, with slack-reinforced or prestressed concrete (4) in such a way that only the upper end (5) having the head bolts (6) remains free. The encasing concrete (4) provides a bearing surface for precast slabs (10), in-situ concrete (11) being poured to complete the ceiling. In this way, while using a steel-saving section an inexpensive fire-resistant casing is achieved, which additionally guarantees the erection stability of the section. Shuttering at the site is unnecessary. <IMAGE>
