Title: Tobacco filter rod production process - slows down and compresses strip after stretching and before concentration
Inventor: ZINK LEONHARD
IPC: A24D3/02
Filed: 1979-10-04
Abstract: The system produces tobacco smoke filter rods, particularly for cigarettes, forming a continuous filter strip of crimped textile fibres, which is stretched, released and concentrated into a strip, enclosed by a wrapping and parted off. In order to increase the release action after stretching and before concentration, the strip movement is slowed down and it is compressed before concentration. This can be done by two plates (9,10) after the last pair of stretching rollers (8), forming between them a space (11) into which the strip (1) is thrust by these rollers, and compressed in the process.

Title: Arrangement testing hardness of small workpieces - has microphone picking up frequency distribution as workpiece lands on support and supplying comparator controlling deflector
Inventor: OSTERMANN ALBERT VON DIPL ING
IPC: G01N29/14
Filed: 1979-11-20
Abstract: The hardness of continuously and sequentially delivered workpieces, esp. small ones, is tested. They are allowed to fall upon a non-oscillating support. The frequency distribution of the sound produced as the workpieces hit the support is compared with a stipulated frequency distribution corresp. to a desired degree of hardness.

Title: Hub cap for vehicle wheel - has spokes with blade profile to produce air flow preventing deposition of brake lining dust
Inventor: DIESENBERGER ALBERT
IPC: B60B7/18

Title: Human jaw movement determination method - using electronic measurement detectors for movement of bottom jaw
Inventor: SCHMIDT HANS-HELMUT DR
IPC: A61C19/045
Filed: 1980-01-23
Abstract: The method determines the distances and/or movements of the human top and/or bottom jaws in relation to the skull, also the positions of top and bottom jaws in relation to each other. In a first stage an infra-orbital reference plane is determined at the top jaw, defined by three or more datum points, these including the infra-orbital and two hinge axis points. In a second one, movements of the bottom jaw in various planes in relation to this plane are determined. Determination of movements of the bottom jaw (22,22') is effected electronically by measurement detectors. The values detected can be used to simulate jaw movements on a mathematical model in a data-processing machine.

Title: Metered disinfectant admixture control to water - has vessel divided by bladder into chambers for disinfectant and pressurised water
Inventor: WIENHOLD WILLY
IPC: E03C1/046
Filed: 1980-02-01
Abstract: The appliance is for metering and admixing of a disinfectant directly into a pipe leading to a water tap. Parallel to the pressurised delivery line from the metering vessel to the tap is a drain line for the high-pressure water, with a solenoid valve, automatically controlled as a function of the flow rate and open when the tap is closed. The other chamber of the metering vessel, which is inside a bladder, contains the disinfectant and is joined through a non-return valve and a suction line to the disinfectant storage container.
