Title: Constant-velocity swivel joint
Inventor: WELSCHOF HANS-HEINRICH DIPL IN
IPC: F16D3/226
Filed: 1986-08-08
Abstract: The invention relates to a constant-velocity swivel joint in the form of a sliding joint or a fixed joint, in which at least one novel retaining ring 19 for one of the joint inner parts, i.e. the ball cage 5 or the inner joint body 7, is provided as an axial stop, which is inserted into a circumferential groove 21 on the inside of the outer joint body 1, there being provided on the retaining ring 19 an annular stop face 20 for the joint inner part 5, 7 and this stop face can enter into at least linear contact with the joint inner part, and corresponding tapered supporting surfaces being formed on the retaining ring 19 and in the circumferential groove 21, their angles of taper opening towards the joint inner part 5, 7. In a special embodiment, the angle of taper of the supporting surface 22 corresponds to that of a tangential annular surface on the joint inner part 5, 7 in the region of contact with the retaining ring 19, which is situated, in particular, at the edge of the spherical outer surface of the joint inner part 5, 7. In particular, half the angle of taper of the supporting surface 22 can be approximately equal to or greater than the angle of sliding friction between the retaining ring 19 and the joint outer part 1, with the result that, when there is axial loading on the supporting surface 22, self-locking occurs. Joints with two retaining rings according to the invention are also proposed. <IMAGE>

Title: Toothed-belt drive
Inventor: KLEINHOFF KLAUS DIPL ING
IPC: F16G1/28
Filed: 1986-09-02
Abstract: The invention relates to a toothed-belt drive, particularly for bicycles, for the transmission of torque from the crankshaft to the rear wheel. The drive consists of a large sprocket at the front, a small sprocket at the rear having the minimum number Z of teeth, and a toothed belt of pitch S wrapped around the two sprockets, the said belt being composed of low-loss rubber or rubber-like materials and having inserts of high tensile strength. In order to improve the wrapping of the rear small sprocket, where the toothed belt has a tendency under high loading to climb radially out of the intertooth gaps in the sprocket and to skip one tooth spacing, it is proposed that the normals of the belt flanks, at least those of the load-transmitting flanks, be inclined by a maximum of 34 DEG relative to the chordal direction and that the radius of curvature of these flanks be greater than 3/4S at all points, the radius of curvature of the load-transmitting flanks on the sprockets being slightly greater than on the belt at each point of contact, and that the centres of curvature of the flanks be at a distance of no more than 0.1S from the secondary datum lines which mark the thinnest points of the belt, this distance being greater on the belt toothing than on the sprocket toothing. <IMAGE>

Title: Sales counter (sales cabinet) with upward-projecting, inclined supports
Inventor: STENEMANN BRUNO
IPC: A47F3/00
Filed: 1986-11-15
Abstract: In the case of a sales counter, upward-projecting, inclined supports are required to fix connecting parts such as carriers or arms thereto, for which a link chain is required to bridge the angled course between the connection part and the support. To achieve a connection between a connecting part and its support which is inexpensive and quick to produce, it is proposed to use as the link chain merely a screw with a bent shank and a head, on the free shank leg of which screw a nut is screwed. The bent shank is pushed through a hole in the wall of the hollow section and its head bears against the outside of the wall. The free shank leg of the screw projects through a bore in the connecting part, and on the opposite side of the connecting part the nut is placed on the leg end of the bent shank.

Patent DE-3715626-A1 (DE)
Title: U-shaped closure clip for bags and tubes
Inventor: NIEDECKER HERBERT DIPL ING
IPC: B65D33/16
Filed: 1987-05-11
Abstract: In U-shaped closure clips for bags and tubes of strip-like material, the clip consisting of a clip base 1 and two limbs 2, 3, and the ends of the limbs of the clip being bent outwards and forming a connecting web 4, by means of which the clip is linked separably in a strip, there is a requirement for not having to classify the size of the closure clip too finely for packaging tails of different thicknesses. Additionally, it is desirable to use less clip material and to be able to provide the processor with clips which are as narrow as possible in order to require less packaging material. This object is achieved in that, in such clips, the strip thickness of the limbs 2, 3 decreases continuously at the connection to the clip base 1 or from its peak region 5 to the end of the limbs 2, 3. Additionally, the ratio of the strip width to the greater strip thickness can be less than two, but greater than 1. <IMAGE>

Patent DE-3726627-A1 (DE)
Title: Projectile
Inventor: BEUTIL HORST DR ING
IPC: F42B12/10
Filed: 1987-08-11
Abstract: Primarily for attacking targets (Z) which are armoured by means of an outer protective layer (S) containing explosive (reactive armour). A projectile, for example a rocket, has a wall (W) at the front, instead of the tip, on striking a target (Z). The wall (W) represents a stamping and pressing tool (W) having a front surface (W) which is formed in a concave shape seen from the target (Z) and, on impact, deforms a region (B) of the protective layer (S) located in front of the front surface (W), by means of more or less distinctive stamping and compression of this region (B) to form a mass (M) which contains explosive and is more or less convex, seen from the projectile. Furthermore, with respect to a longitudinal section through the projectile containing the projectile axis, on the one hand the ratio of the depth (t) (measured in the direction of the projectile axis) of the concave front surface (W) to the diameter (d) measured at right angles to the projectile axis and to a length of the diagonal (d) of the front surface (W) measured at right angles to the projectile axis is greater than, on the other hand, the tangent of the angle (x) between the projectile axis direction and the envelope line of the projectile outer casing (A) close to the wall. Attacking vehicles (Z), for example ships (Z) and armoured vehicles (Z), as well as bunkers (Z) which are in each case armoured by protective layers (S) containing explosive.
Patent DE-3727248-A1 (DE)
Title: Power amplifier for an inductive load
Inventor: KEMPE MANFRED DIPL ING
IPC: H03F3/30
Filed: 1987-08-15
Abstract: A power amplifier is created, in the form of a complementary push-pull amplifier having a linearised transmission characteristic (AB mode), which reacts virtually without any error if the load is inductive. Such a power amplifier is particularly suitable for common supply of a variable number of inductive measurement variable pick-ups and thus for the construction of a multi-point measurement system, in the case of which only the output signal of the measurement variable pick-ups is switched over. The high constancy of the output voltage in the event of a changing inductive load is achieved in that, using two complementary emitter followers (EF1, EF2) whose quiescent currents are stabilised by emitter resistors, the current required by the load is produced without the voltage drop occurring on the emitter resistors (9, 9') in the load circuit making compensation by the operational amplifier (1) necessary. <IMAGE>

IPC: G01N15/06
Filed: 1988-01-20
Abstract: A method for measuring the concentration of dust in the air which can be carried out in a simple way and works cost-effectively is provided, in that the precipitation of the airborne particles from a specified measuring volume is brought about by means of a corona discharge. The corona discharge is pulse-operated. Natural convection currents are used for filling the measuring volume. After the corona discharge in the time te, the charged particles subsequently have available to them the time ta for the precipitation. Filling of the measuring volume is achieved during the time tk, upon which the cycle begins anew with the next corona discharge. No significant losses of larger particles occur in the convective filling process of the measuring volume.
