Title: Simultaneous checking of membrane insert integrity - comprises using partially soluble gas introduced below bubble point pressure and detecting subsequent bubble formation within insert without removal from installation
Inventor: SCHULZ HERBERT
IPC: B01D29/21
Filed: 1992-05-12
Abstract: In a process to check the integrity of a number of membrane filter inserts in one operation, each filter unit has an inlet chamber and an outlet chamber for the filtrate. The filter unit is so positioned that the filtrate collection chamber is above the membrane filter insert. The inner space within the membrane filter insert is filled with fluid.

Patent DE-4229585-A1 (DE)
Inventor: RUNGE WOLFGANG DR ING
IPC: F16H61/00
Filed: 1992-09-04
Abstract: In a device for regulating the reduction ratio of an infinitely variable transmission, a stationary speed of rotation set value of a driving motor is taken from a three-dimensional characteristic field of operation. The stationary speed of rotation set value is supplied to a signal input of a set value filter (3). This set value filter (3) allows the evolution of an instationary speed of rotation set value to be modified by appropriate association with an indicial response when the stationary speed of rotation set value is abruptly changed. A regulation strategy can thus be achieved for ensuring a static and dynamic regulation behaviour which takes into account the subjective driving feeling and economic considerations.

Patent DE-4314841-A1 (DE)
Title: Carriage with spring-mounted shaft
Inventor: SCHLADT MICHAEL
IPC: B62C5/02
Filed: 1993-05-05
Abstract: Carriages, which are envisaged for equestrian sport and for training horses, frequently also have to be moved in open country. The height differences arising in this connection in the region of the shaft tip are compensated by spring elements which are arranged in a tube and which constitute the connecting element between shaft and bogie of the carriage. These spring elements are connected to the shaft and the tube respectively via a fixing screw which also serves as a height-adjustment arrangement together with a tooth rack. A very versatile shaft connection is thus produced, which is optimally suited for sport and also normal operation. <IMAGE>

Title: FM-modulation method for digital carrier signal
Inventor: GOECKLER HEINZ DR ING
IPC: H03C3/00
Filed: 1993-06-24
Abstract: The method FM-modulates a digital carrier signal with a digital LF signal using a fed-back phase accumulator and a carrier oscillator, which generates the sampling value of the modulated FM-carrier oscillation or of the FM-signal. The carrier oscillator (COSZ) operates with a sampling rate fA = 1/T, which is greater than the FM band width. A complex-valued FM carrier signal is generated whereby the carrier frequency of the non-modulated carrier is fC = M.fA+f0, with the whole number M > 1 and the FM intermediate frequency f0. A filter (F) with complex-valued coefficients band limits the signal which is interpolated by a complex-valued interpolation filter.
