Patent DE-3844746-A1 (DE)
Title: Connecting rod
Inventor: SWARS HELMUT DIPL ING
IPC: B21D39/20
Filed: 1988-11-03
Abstract: The invention relates to a connecting rod which is designed as a composite hollow body consisting of a plurality of components. An outer layer of material is subject to a tensile prestress owing to internal supporting means that accept pressure in the radial direction, the said tensile stress prevailing essentially over the entire axial length of the connecting rod and in each case being uniform around the circumference. The supporting means are formed by a plurality of annular or sleeve-shaped bodies (22, 23, 24) resting against the outer layer (21) over parts of their circumference, in conjunction with shaped bodies (25, 26, 27, 28) situated between them and the annular or sleeve-shaped bodies (22, 23, 24) are composed of a material which has a lower yield point than the outer layer (1, 11, 21, 35) and which is expanded plastically in situ. <IMAGE>

Title: Firework rocket
Inventor: GARMS THOMAS
IPC: F42B4/06
Filed: 1989-01-27
Abstract: Firework rockets are used for visual and audible entertainment. They should therefore offer appealing effects. Previous firework rockets normally offer only one effect, so that the object of the invention is to create a firework rocket having effects which differ from the normal. The firework rocket according to the invention produces a particularly attractive effect in that a functional charge (28) is arranged above the effect charge (27), and can be fired and detonated together with the effect charge (27) in order to achieve two at least simultaneous effects. The invention is particularly suitable for firework rockets which are normally fired on New Year's Eve, but for signal rockets or flares as well. <IMAGE>
Patent DE-3908355-A1 (DE)
Inventor: BENKESER MICHAEL DIPL ING
IPC: B01D17/025
Filed: 1989-03-15
Abstract: A liquid separator, in particular for separating mixtures of water and liquids of lower specific gravity, such as oil, petrol and the like, comprises a container having an upper inlet with inlet constriction and an outlet at about the same height as the inlet and opposite it, a separating part following the inlet part and having a discharge near the base, adjustable depending on the liquid level, and a discharge tube extending upwardly therefrom to the outlet. To extend the residence time and provide long flow paths and thus to optimise the degree of separation, the separator part comprises an annular chamber following the inlet constriction, said annular chamber being formed by the wall of the container and a separating wall approximately concentrically enclosing the container centre and extending to the outlet side, and the inner chamber, formed by this separating wall, in the container centre, which chamber contains the discharge into the discharge tube.

Title: Hardening of steel parts by heating and quenching - using glycerine or a glycol, esp. ethylene glycol, as quenching agent
Inventor: HEIBERGER ERNST
IPC: C21D1/56
Filed: 1989-08-01
Abstract: Steel parts are hardened using either glycerine CH2OH-CHOH-CH2OH or glycols R2HC(OH)-(OH)CHR2, esp. ethyleneglycol HOH2C-CH2OH, as quenching agent. USE/ADVANTAGE - Use of glycerine or glycols is more economical than using oils as quenching agent, and does not leave a residual oil film on the hardened steel parts.

Patent DE-3925900-A1 (DE)
Inventor: GAMMONS TIMOTHY SIMON
IPC: E21C35/24
Filed: 1989-08-04
Abstract: The trailing drum (6) of a double-ended ranging drum shearer is steered in a seam (1) by producing an algorithm which determines, as a result of information derived from signals from the machine dependent on its tilt, direction and amount of movement along a face being cut. The height of the leading drum is used as a reference from which to determine the optimum position of the trailing drum in order that a constant quantity of desired mined material is obtained. To measure the tilt of the machine a transducer arrangement is used which comprises a pair of vertical parallel tubes joined at their lower ends by a horizontal tube and with a liquid filling the horizontal tube and part of the vertical tubes, and including a separate transducer at the top of each vertical tube. <IMAGE>

Title: Catalyst for oxidising sulphur di:oxide to tri:oxide - has silica support with specified pore dia. distribution impregnated with activator
Inventor: MEISSNER RUPRECHT
IPC: B01J23/22
Filed: 1990-01-11
Abstract: Catalyst for oxidn. of SO2 to SO3 consists of a SiO2 support activated with V and alkali metal cpds. The support: has a pore vol. fraction of 10-30% pores with dia. up to 15nm, 25-60% pores with dia. 15-200 nm and 10-60% pores with a dia. of over 200nm.

Title: Cable twisting - uses material take=off drum and conveyor screw with twisting core to give fine strands in left and right twist
Inventor: MARX KARL-HEINZ ING GRAD
IPC: D07B3/00
Filed: 1990-10-30
Abstract: To give a continuous cable twisting action to strands such as of electrical cores or filaments or wires or strands of metal, plastics, mineral, (in)organic materials, the material (5) is drawn from fixed bobbins (6) through a guide (7) in parallel and at an adjustable angle to the take-off drum (8), pref. at the pitch angle of the conveyor screw (11). The material is wound round the take-off drum (8) through the power (10) rotation of the drum. The material is transferred from the take-off drum (8) to the conveyor screw (11), from the mounting housing (9), while rollers (13) maintain the parallel lie of the material (5) round the drum. The pitch angle of the threading round the screw (11) advances the material (5) to the twisting core (12), assisted by continuous belts (15) on both sides of the screw (11), to move the strands to the free conical end of the twisting core (12). After the material has left the twisting core (12), it is drawn in an axial direction for further twisting in a beaten length matching the circumference of the take-off drum (8) together with an increase through the preset pitch of the conveyor screw (11). The drum circumference and screw pitch can be adjusted to vary the beaten length of the twisted cable, as can the direction of drum (8) rotation and a left or right screw (11) to give a left or right twisted cable. ADVANTAGE - The appts. gives twisted cables in left and right twists, using thin and flexible strand material.

Title: Detecting cornering instability of two track motor vehicle - monitoring wheel-speeds to compute slew values for both axles and determine stability by comparison
Inventor: SCHWARTZ EKKEHARD
IPC: B60K28/16
Filed: 1991-04-10
Abstract: The speed of each wheel is measured and processed for each axle to compute a slew value. If the difference in the slew vaues for the two axles exceeds a preset level, instability is detected. Non-slew cornering occurs when each point of the vehicle has a similar moment about the cornering centre. The method uses the existing wheel-speed sensors of the ABS braking control and the wheel-spin control. No transverse movement detectors are required. The control system uses some of the logic of the ABS/ wheel-spin control. ADVANTAGE - No complex sensors required.
