Title: Method and arrangement for shaping a spectacle glass
IPC: B23K26/08
Filed: 1988-02-11
Abstract: The invention relates to a method and an arrangement for shaping a spectacle glass, starting from a raw glass, the region between the circumference of the raw glass and the circumference of the shaped glass being removed, with the aid of a separating tool, by a separating cut being made from separating-cut sections radially from the circumference of the rotating raw glass towards the circumference of the finished glass, then along or parallel to this circumference and finally radially back to the circumference of the raw glass. The aim of the invention is to indicate a method, with which, with constructionally simple means, a finished glass, i.e. a spectacle glass with a given circumference and a desired circumferential glass edge, can be obtained from a raw glass in a time-saving and labour-saving manner. The method is characterised in that the spectacle glass, which is clamped in between two half-shafts, is provided with a number of mutually spaced radial separating-cut sections and in each case, lying between these, a circumferential separating-cut section, and, at an angular spacing therefrom and during the making of the respective separating-cut sections, a finish-grinding is carried out over the entire circumference of the cut-out glass. <IMAGE>

Patent DE-3811519-A1 (DE)
Title: Adjusting device for play-free bearing adjustments in the radial and axial direction of a shaft by means of an adjusting nut
Inventor: SCHWARZ EMIL
IPC: F16C19/54
Filed: 1988-04-06
Abstract: With shafts which have to be play-free, bearing adjustment is a time-consuming operation. In addition, use is made of axial spacers which have to be produced very accurately and are therefore expensive. In addition, there is generally the fact of repeated removal and insertion for the selection of the spacers. The adjusting device eliminates the production of the spacers and adjusting can be carried out rapidly and without problems. In order to meet the requirements of the bearing seat, the adjusting nut is provided with two press fits and the same object is thus achieved as if the bearing ring were pressed onto the shaft against an axial stop. However, the bearing ring can be adjusted with the adjusting nut. This arrangement permits use in the construction of machines, vehicles and transmissions, e.g. wheel bearings in vehicles or spindles of machine tools.

Title: Central-locking system for doors and/or flaps of motor vehicles
Inventor: KASTNER MICHAEL DIPL ING
IPC: E05B65/38
Filed: 1988-05-26
Abstract: The invention relates to a central-locking system, in which, in addition to the central-locking function per se, an additional break-in safeguard is provided. The aim is, at the same time, to ensure that, when the vehicle has been locked from outside (for example, by lock-cylinder actuation), it is no longer to be possible to unlock it via the locking buttons (27) provided on each of the vehicle doors and to be actuated from the passenger space. In a corresponding design of the central-locking system, according to which door locks (15) loadable by locking mechanisms are provided and these door locks are assigned, in turn, setting elements (1) which are coupled to one another in a manner transmitting setting commands, provision is made, according to the invention, during the actuation of a locking mechanism (19) accessible from outside the passenger space, for initiating via suitable control means (30) an at least double activation of each setting element (1) taking place successively in time. As a result of this activation of the setting elements (1) which is now at least double, in contrast to the initiation of central locking via the locking buttons (27), the door locks (15) are shifted into the desired state at a minimum outlay in terms of control and apparatus (Fig. 1). <IMAGE>

Title: Internal combustion engine with irrotational pistons
Inventor: MIRCEA CRALEA DIPL ING
IPC: F01B3/06
Filed: 1988-09-16
Abstract: The invention relates to an internal combustion engine with irrotational pistons without crankshaft and with a conversion movement principle in which the translational motion of the piston is converted into rotary motion by a special double guide. The pistons are directed to the working cylinders by a closed "sinusoidal" curve and at the same time guided on 2 guide channels of a conversion axis opposed by up to 180@. The rotary motion of the said conversion axis is transmitted by gears. Actuation of the valves is performed by a face cam disc, either directly or by way of a rocker lever, which cam disc may also have the function of a flywheel and Comprex system drive (variants). Advantages obtainable: absence of difficult (design technology - price) parts such as crankshaft and camshaft, reduction of the masses and centrifugal forces, overall engine height, simplification of lubrication - slide bearings are or may be replaced by roller bearings, compact construction and cheap.

Title: Capacitor cup housing
Inventor: KLASCHKA RUDOLF
IPC: H01G4/224
Filed: 1988-11-04
Abstract: The invention relates to a capacitor cup housing made of material which can flow, especially aluminium, having a weak bursting point arranged on the base of the housing, the base of the housing having at the edge a region which is reinforced in the form of a circular ring, while the radially internally located circular base region is designed to be weaker. The weak bursting point consists of a single, essentially diametrically running, slot-like wall weakened region which runs in a slot-like or bead-like deep-drawn region (thermoformed region) and, in its region, the base is notched-in both from the inside and from the outside. This arrangement is intended to avoid a high level of deformation consolidation in the production of the slot-like wall weakened region so that, with the same bursting pressures, the remaining material link between the two notches can be loaded to a greater extent. In consequence, manufacturing safety (manufacturing reliability) is significantly increased overall.
