Title: Air spring for passive vibration insulation - has additional stiff springs with low damping properties arranged to absorb cross-ways vibration
Inventor: HEINZE WERNER DR ING
IPC: F16F15/023
Filed: 1976-09-22
Abstract: The air spring is for weakly sprung location of machines on bases, partic. for passive vibration insulation and comprises a normal unit with membrane seal and level adjustment for simple springing axially, and additionally one or several springs with low material damping properties. These latter springs take over the crossways springing duty, and at the same time can be stiff axially. Other measures to be used involve reduced mass of vibration-prone machine components, damping of such components using vibration absorbing materials, the introduction of additional dampers, or the displacement of resonance frequencies to higher levels by increasing individual spring rigidity.

Title: Tampon esp. for feminine hygiene - has withdrawal thread bonded to fleece, permitting continuous production at higher speeds
Inventor: STEFFENS BERT
IPC: A61F13/20
Filed: 1976-10-16
Abstract: A tampon, esp. for feminine hygiene, has a recovery thread drawn through the wadding once or twice by a needle. The improvement comprises the withdrawal thread being laid on the surface of the fleece, and being bounded inseparably at one or two points to the fleece where it runs parallel with the long edged of the wadding. The remainder of the thread is turned so as to run parallel to the short edges of the piece and extend beyond the long edge. Pref. the recovery thread is bonded tothe fleece at the start and finish of the section parallel to the long edges. An adhesive is used for fixing the thread to the fleece. The recovery thread and/or teh fleece is of plasticisable material and is welded together without extraneous matter. The free end of the thread leaves from a centre point in the bottom face of the tampon and has a knot. Prodn. is carried out in an installation having a horizontal conveyor for the wadding fleece, and, in the line of motion, a feeder for the thread, a device for bonding thread to fleece, a shear to cut the thread to length, an arrangement to turn a section of the recovery thread, a parting off arrangement and rolling up device. The withdrawal thread does not tighten up the tampon and extend when pulled for recovery, fewer winding s are therefore necessary than for a tampon in which the thread must tigthen first. The winding of the tampon can be arranged so that the thread extends from the centre of the finished tampon. Prodn. can be carried out much more quickly in an absolutely continuous process.

Title: Stop watch velocity scale for vehicle speed measurement - has scale with min. and max. values displaced from start position of pointer
Inventor: LEYK KLAUS
IPC: G01P3/64
Filed: 1976-10-26
Abstract: The velocity-measuring stop-watch for determining the speed of vehicles over a specified distance consists of a single pointer stop-watch mechanism whose pointer makes one revolution per minute. If the measured distance travelled by the vehicle is one kilometer, then one revolution of the pointer corresponds to a speed of 60 km/h. To increase the reading accuracy of the dial, particularly for the higher speeds, the start of the scale and the end of the scale do not coincide with the datum position of the pointer (13) but are displaced by approx. 90 deg.. The first part of the scale will therefore be used for low speed values only during the second revolution of the pointer (0-60 km/h).

Title: Operating a calciner under a pressure differential - by using a sealed shroud around the soaking pit area
Inventor: KRANZ RAY E
IPC: C10B7/02
Filed: 1978-05-05
Abstract: Materials within a calciner evolve volatiles when subjected to heat treatment. The calciner has an exhaust stack for the flow of combustion gases and a soaking pit area. Some of the combustion gases from the exhaust stack are directed to combustion gas admission ports in the soaking pit area to provide an increase in pressure in the pit. This prevents outside air from entering into it and coming into contact with the materials which have been heat treated within the calciner and which have been deposited into the soaking pit area. The method increases the yield of fixed carbon in the already processed carbonaceous materials. Also the yield in the percentage of metallisation is increased when the calciner is employed for the simultaneous production of metallised ores and coke.
