Patent DE-3233854-A1 (DE)
Title: Reciprocating piston pump
Inventor: BECKER ERICH
IPC: F04B3/00
Filed: 1982-09-11
Abstract: A reciprocating piston pump has at least one sealing sleeve which has one section extending radially and held at least partially by the piston part as well as a lipped area forming a seal with the cylinder wall. The wall thickness (d) of the sleeve section (11) extending radially is greater than the wall thickness (b) of the lipped area (12) of the sealing sleeve (10). According to a particular further development, the internal width of the pump cylinder in the centre area of the piston stroke movement is slightly constricted. In the pump a good bearing of the comparatively thin lipped area (12) of the sealing sleeve (10) is achieved which at the same time results in strong lateral support of the reciprocating piston. The sleeve section (11) extending radially and designed with a greater wall thickness is fully capable of bridging the annular gap between the reciprocating piston and the wall of the pump cylinder. With this reduced internal width of the pump cylinder in the centre area of the piston stroke movement, this reduction counteracts any increase in the gap between the reciprocating piston and cylinder wall as a result of the inclined position of the reciprocating piston. <IMAGE>

Patent DE-3324231-A1 (DE)
Title: Control device, in particular for program switches
Inventor: PASQUIER PATRICK
IPC: H01H3/44
Filed: 1983-07-05
Abstract: The control device, in particular for program switches in electrical domestic appliances, has cams (1, 2) which control a multiplicity of contacts (1a, 2a). These cams can be turned by an electric motor (M) via a reduction gear. Part of this reduction gear comprises a satellite gear wheel (9) which is mounted in such a way that it can oscillate on an eccentric (10) and is in engagement with a planetary gear wheel (15) which for its part is seated firmly on an output gear wheel (14). This output gear wheel consequently turns at a non-constant rate. The splining of the output gear wheel (14) and of the cams (1, 2) is configured in such a way that, during each advancing step of the cams, they exhibit a rotational speed which successively runs through a first phase with a speed which is initially rapid and then slowed to zero, thereupon a second phase with zero speed and finally a third phase with a speed which initially grows and increases rapidly from zero. During the first and third phases, of about 0.2 seconds duration in each case, the contacts are actuated in two groups, to be precise during advancements of two half-steps of 3 DEG  each at a time.

Title: Shear closure hook for a tensile connection
Inventor: FISCHER REINHOLD
IPC: A01K1/064
Filed: 1983-10-05
Abstract: Such a shear closure hook is used especially on towing cables (7) or towing bars for motor vehicles, in general for land vehicles, water vehicles and aircraft, and on chains for animals. The arrangement of a shear closure hook can be made on one or both ends of the tensile means. In this case, the shear closure hooks are in each case formed from two hook parts (1 and 2), which rest flat on one another, are held together by means of a bearing sleeve (3) and can rotate relative to one another about the centre axis (6) of the bearing sleeve (3), the tensile means (7) running through the bearing sleeve internal space, and the hook parts (1 and 2) supplementing one another in the closed position (8) to form an eye (9) which is closed over the circumference. Towing cables (7) or towing bars are subject to increasing tensile stress in the event of reductions in separation and track deviations of the towing vehicle, as well as to certain lateral force components which can exert disadvantageous influences on the hook parts (1 and 2) of a shear closure hook. In order to counteract the undesired opening of the hook parts (1 and 2) without significantly hindering the process of deliberate release of the tensile connection, it is proposed that the hook parts (1 and 2) in each case be subject to the force of at least one stressed closing spring (10) in the closing direction (11), and that the closing spring (10) be subjected in the closing direction (8) to a prestress which can be cancelled out by hand. <IMAGE>

Title: Centring device for an optical fibre
Inventor: MELMAN PAUL
IPC: G02B6/38
Filed: 1983-12-30
Abstract: A centring device holds an optical fibre along an axis by means of three parts of a fibre-retaining device and a retainer element. The retainer element has a concentric cylindrical cutout or opening which holds the parts assembled. The parts are essentially identical, and in each case have a uniform cross-sectional shape at right angles along a main part of their length. The opening ends in a planar wall at right angles to the axis. It can contain an axially aligned depression in the shape of a conical frustum. In this way, an inserted fibre is guided smoothly along a wall of the depression and stopped when the cross-sectional dimensions of the depression are no longer greater than the diameter of the inserted fibre. It is desirable for the end of the fibre to be arranged at the focal point of the retainer element. <IMAGE>

Patent DE-3444942-A1 (DE)
Title: Method and device for the long-term conservation of moist cereals
Inventor: TALLAFUS OTTMAR DIPL ING
IPC: A23K30/00
Filed: 1984-12-10
Abstract: Silos through which protective gas or protective gas mixtures flow have been used hitherto for the long-term conservation of moist cereals. Although the protective gas is guided in a circuit in such installations, there are still very large losses due to leakage. In addition, an installation of this type has to be constantly maintained. This makes its operation very expensive. According to the invention, a cost-effective installation is produced by pouring the material to be conserved into a gas-tight container and then completely filling up the said container with a protective gas which is blown in from the underside of the container. In this way, the material to be conserved is fully and uniformly surrounded by protective gas, which results in excellent conservation which is virtually independent of the moistness of the material poured in. This means that the farmer can remove cereals of a high quality at any time he desires, without impairing the protective atmosphere and therefore the quality of the moist cereals as well. <IMAGE>
