Title: Table
Inventor: LEUTHAEUSSER HILMAR
IPC: A47B27/14
Filed: 1986-06-21
Abstract: To ensure synchronism of their guide struts mounted displaceably in the leg frame, height-adjustable tables contain a horizontal synchronising shaft (8) which necessarily rotates simultaneously with the table top in one or other direction during lifting or lowering thereof. For optional locking of only the lowerability of the table top, a freewheel clutch (10) operates between the leg frame (4) and synchronising shaft (8) and, depending on the direction of rotation, either allows rotation of the synchronising shaft (8) in the lifting direction of the table in a permanently unblocked manner or blocks it in the lowering direction (direction of rotation 23), it being possible to release the lowering block against the pressure of a restoring force by means of a control device (19,20). <IMAGE>

IPC: F01L9/14
Filed: 1986-07-29
Abstract: A hydraulic transmission element is provided for influencing the valve stroke, controlled by a cam, on a reciprocating piston internal combustion engine. The said element essentially comprises a drive piston, a hydraulic working chamber of variable volume, a working piston and a separating tappet dividing the working chamber, which tappet is connected to one of the two pistons. As a result the hydraulic volume is significantly reduced and the risk of pressure oscillations in the hydraulic system is minimised.

Patent DE-3708961-A1 (DE)
Title: Multifunctional insulation system for oscillating surfaces
IPC: B60R13/08
Filed: 1987-03-22
Abstract: Known damping elements consist of layers of a high specific-weight plastic which are embedded between layers of flexible plastic, foam or nonwoven fabric. They have a narrow-band acoustic effectiveness whose optimum is at 10 to 15 degrees C and are heavy. The bitumen used is stiff and difficult to handle at room temperature. The novel insulation system is lightweight and cost-effective and has a broad acoustic effect. The insulation system has no bituminous layer filling or impregnation and additive coordination of such layers is dispensed with. The surface to be insulated has allocated to it a foam layer with high acoustic internal loss factor and predominantly plastic characteristics with low elastic recovery. Further layers may follow to optimise the effect. Various formulations are specified for the foam layer. By virtue of the hydrophilic character of the formulations, non-polar groups form on the surface during crosslinking, which possess a high adhesion to metallic surfaces.

Patent DE-3719439-A1 (DE)
Title: Frequency-measuring method for digital tachometers
Inventor: FRENK HELMUTH DR
IPC: G01R23/10
Filed: 1987-06-11
Abstract: In the case of the use of incremental transmitters as tachometer generators, frequency multiplication is often required for the purpose of avoiding dead times when rotational speeds are very low. Phase errors in the derived phase-shifted frequencies feature in such a multiplied frequency as strong frequency errors. However, according to the invention, for the purpose of measuring the frequency use is made not of the multiplied frequency, n.f., but of the (n/2) phase-shifted rectangular voltages of the frequency f, in order to determine the total period from rising to rising then from falling to falling edge, e.g. digitally by counting and dividing the counting (counter) frequency by the result. n Results, which are no longer impaired by phase errors are thus obtained in every period.
Patent DE-3727609-A1 (DE)
Title: Automatic shifting device for bicycle gear shift mechanisms
Inventor: ZEMANN HERBERT
IPC: B62M9/08
Filed: 1987-08-19
Abstract: The automatic shifting device comprises two parts. On the one hand, the shaft having the gear wheels and the spreading arms, on the other hand, the hub drum having the spiral grooves and the clamping pieces. The spreading arms are guided with one side in the spiral grooves while the other side is pivotably fastened on the shaft. When the shaft is driven by the chain, the spreading arms spread away from the shaft as a result of the resistance of the rear wheel. This movement is transmitted to the shifting gear wheel. Depending on the size of the resistance, the correct gear is now selected. The clamping pieces ensure the locking of the respective gear.
Patent DE-3732766-A1 (DE)
Title: Permanent-magnet-excited hysteresis coupling or brake
Inventor: FLOERCHINGER GERHARD
IPC: H02K49/06
Filed: 1987-09-29
Abstract: A permanent-magnet-excited hysteresis coupling is described which has a hysteresis part (1), which is constructed as a bell-type rotor, and an excitation part (2), which consists of an inner and an outer pole ring (3, 4), the magnet poles being arranged on both outer surfaces of the bell-type rotor. The essential feature in this case is that the pole rings (3, 4) consist of soft-magnetic material and permanent-magnet pieces (5, 6) which are completely embedded in the soft-magnetic material, so that magnetic poles facing the bell-type rotor are formed alternately by the permanent magnet and the soft magnet. Furthermore, the outer and the inner pole ring (3, 4) are rigidly connected to one another but are magnetically separated by an intermediate ring (7) which cannot be magnetised. A major saving in high quality (high cost) magnetic material is achieved here, with a simple type of design. An adjustable torque can be achieved by a variable insertion depth of the hysteresis ring body (2), for example by means of a threaded spindle (14) and lock nut (15). In addition, the pole rings are aligned such that poles of the same type are in each case radially opposite from the outer pole ring to the inner pole ring. <IMAGE>

Title: Fringe contrast arrangement
Inventor: DANZ RAINER DIPL PHYS
IPC: G02B21/08
Filed: 1987-12-22
Abstract: The invention relates to a fringe contrast arrangement which can be used in optical instruments which operate using polarised light, in particular in microscopes. It is preferably used for high-contrast (contrasty) representation of unstained objects (specimens, samples). The aim is to achieve a substantial increase in contrast and for the direction of image splitting to be arbitrarily selectable. The object is achieved according to the invention by means of a fringe arrangement by providing elements in the optical beam path which generate circularly polarising light and whose directions of oscillation relative to one another and to the direction of oscillation of the polars are arranged at defined angles. The object is investigated using circularly polarised light, and the direction of image splitting can be varied.

Title: Leather-working appliance
Inventor: ZAEPFEL HORST DIPL ING
IPC: C14B1/28
Filed: 1988-09-13
Abstract: What is specified is a leather-working appliance, especially dewatering machine, in which the leather rests over its surface on an endless conveyor band (2), deflected via at least one front (3) and one rear (4) deflecting roller, and is conveyed through at least one leather-working station (7, 35). In such leather-working appliances, the surface measurement of the worked leather increasingly assumes importance. There have been known hitherto separate measuring machines which are arranged downstream of the leather-working appliance, but which have a relatively high space requirement. Moreover, inaccurate surface measurements can occur as a result of the overturning of the leather parts during conveyance from the leather-working appliance to the measuring machine. The invention specifies a leather-working appliance (1) which, with a small space requirement, allows an accurate determination of the surface size of the worked leathers. For this purpose, a surface-measuring device (8) is arranged in the leather-working appliance at the exit of the latter. <IMAGE>
