Title: Glass banks for drawing optical waveguide fibres - made by centrifugal casting of doped quartz glass in centrifugal mould rotated at high speed
Inventor: HEITMANN WALTER DR ING
IPC: C03C13/04
Filed: 1980-01-10
Abstract: A melt is made of silica glass (SiO2), and dopants possessing a different density and different refractive index (RI) to the glass are added to the melt. The melt is made in, or poured into, a cylindrical mould made of heat-resistant material; and the mould is heated to a temp. between the softening point and the m.pt. of the glass, and is rotated at high speed on its axis for a specified time (T), after which the mould is cooled so the melt solidifies. Time (T) pref. causes the dopants to form a thin edge zone on the blank. The dopants may possess (A) a higher density and a lower RI than the SiO2; or (B) a lower density and a higher RI than the SiO2. The blank may be placed in a tube of known RI before both are heated and drawn into fibres. Conventional methods of mfg. blanks, e.g. by CVD, are very slow; the invention provides a much simpler and faster method of mfg. blanks.

Title: Control circuit for camera film winder - has torque operated isolating clutch and time delay circuit long enough to permit frame movement
Inventor: MAIDA OSAMU
IPC: G03B1/12
Filed: 1980-02-06
Abstract: The automatic control circuit is for a film wider in a camera and has the motor drive activated by a signal generated by the closed shutter.

This provides a rapid and accurate film index control with no damage to the film or the drive. The film drive otor is linked to a time delay circuit sufficiently lon for a frame movement so that the isolating clutch can drop out after a set time delay. The equipment includes a unit for adjusting the moment of rotation of the film transport coupling.

Title: Mixer valve for e.g. shower cold-hot water supply - has temp. regulator for delivered flow using rotary valve element within mixer chamber
Inventor: KOERFGEN HARALD
IPC: F16K31/08
Filed: 1980-05-24

Title: Electromagnetic force compensated balance - has temp. compensation within measurement system using additional coil with temp. dependent current
Inventor: EXNER RAINER ING GRAD
IPC: G01G7/04
Filed: 1980-09-04
Abstract: A balance with electromagnetic force compensation has temp. compensation which is achieved within the measurement system, influences no other balance parameter, and is simple and universally applicable. An additional coil (20) is mechanically coupled to the force compensation coil (8). The temp. regulated current of the additional coil produces a temp. dependent additional force in conjunction with a magnetic field consisting of the stray field of the permanent magnet system (7). The additional coil, which may consist of a single loop of wire, may be built into the coil body of the force compensation coil. The magnetic field may alternatively be produced by a separate fixed magnet or a fixed ferromagnetic component. The coil current may be controlled using a circuit with a predefined characteristic.
