Title: Mute for french horn - has exponential compression section to provide high tone quality without increasing pitch of note
Inventor: KLEIN WOLFGANG
IPC: G10D9/06
Filed: 1976-10-29
Abstract: The tapered coupling section (1) of the mute fits directly into the bell of the French horn. It has a layer of cork to provide a good seal.

Inventor: SUNAMI TERUO
IPC: B22F7/08
Filed: 1977-03-24
Abstract: Process is such that the surface of the basic element, made from an Fe-base metallic material, is coated on the surface with a compressed alloy powder. This alloy comprises a eutectic P alloy with 4-7% P, 1-2.5 wt.% C, remainder Fe, or a eutectic Mo alloy with 10-25 wt.% Mo, 3-5 wt.% C, remainder Fe, or an alloy with 3-5 wt.% C, 2-10 wt.% Mo, 2-10 wt.% W, 5-20 wt.% Co, remainder Fe. The compressed powder is retained on the surface, heated under non-oxidising conditions for a maximum of 30 mins. at a temp. greater than alloy m.pt. and less than material surface m.pt., so that the alloy powder is molten. It is cooled to solidify as a coating which is machined to form most of the lip. Process yields wear-resistant and pore-free seal rings with flexibility to accommodate n uneven surface.
Patent DE-2716647-A1 (DE)
Title: Winding gear jam prevention - uses two component quick setting filler on each cable layer coiled on drum
Inventor: HERMANI RUDOLF F
IPC: A62B1/10
Filed: 1977-04-15
Abstract: The winding gear of the main patent is improved to prevent jamming. This can occur when following a sudden stop, the part of the uncoiling cable length penetrates a gap between two adjacent cable windings, resulting in jamming. A two-component quick-hardening filler is applied to each layer of the cable windings during the winding on. This keeps the individual windings well in place and during the actual use of the gear the hardened filler breaks off the cable as it is coiled off the drum.

Title: Sewage sludge filtration - prolongs filter cloth life by specified anthracite size range admixture
Inventor: SCHLUETTER ALOYS DIPL ING
IPC: C02F11/121
Filed: 1977-07-15
Abstract: The filtration of sewage sludge through filter cloth requires the addn. of filtering aids, pref. aid anthracite which is reduced from a particle size of 2mm. after drying at max. 300 degrees C in an impact mill to 70 mu and sized to a fraction from 30-70 mu. This is used without calcining to form a coating on the filter cloth. This saves the calcining operation, provided the stated size range is maintained. Approx. 30% less anthracite is needed compared with the use of anthracite slurry. The admixt. of the expensive flocculants can be greatly reduced or entirely saved. The life of the filter cloth is increased tenfold.

Title: Braking and re-acceleration of reciprocating object - esp. a sprinkler in a textile coating installation using electromagnets
IPC: B05B13/04
Filed: 1977-12-03
Abstract: An object constantly reciprocating along a fixed path, pref. the sprinkler head of a coating installation, above a continuously, forward moving band of material, such as carpeting, is slowed down and re-accelerated by generating the necessary energy magnetically, pref. electromagnetically. This provides the means of limiting the zigzag path of a sprinkler in a coating installation, so that the zone of deceleration and re-acceleration at the returning point is very small. Uniformity in the coating is thus ensured, and there is the least possible waste of material. At the same time, the minimum of physical force is applied so that energy is not expended in causing wear.

Title: Fade=out control system for cine camera - operates with additional signal supplied to comparator circuit without affecting setting of bridge network
Inventor: KITTAG GERD
IPC: G03B21/00
Filed: 1977-12-14
Abstract: The cine camera is fitted with a bridge network incorporating the exposure sensor to determine the aperture setting. A differential amplifier and a comparator circuit provide the correction signals for the servo motor to set the aperture at its correct value. To control the fade-out and fade-in sequences between scenes a correction signal is generated and fed directly to the comparator. The correction signal bypasses the bridge and uses no mechanical contacts. A solid state switching control is usdd so that contact potentials etc. are avoided. Accurate correction to the aperture is obtained with a simple layout.
