Patent CH-660801-A5 (CH)
Inventor: SCHLAEPPI RENE
IPC: C03B37/12
Filed: 1984-12-14
Abstract: The optical fiber paid out from a reel passes through an extrusion head, then through a cooling vat, the sheath extruded around it being pulled by a withdrawal device. The sheath then passes through a second vat, when the stranding element is withdrawn by an auxiliary withdrawal device under as low a tension as possible. In the second vat, the stranding element is reduced to a temperature lower than the ambient temperature so that contraction of the sheath ensures the excess length of the optical fiber.

Title: Device for generating a pulse in a human dummy
Inventor: BURTSCHER PAUL
IPC: A63H3/00
Filed: 1979-08-30
Abstract: The device is intended to generate a pulse which feels natural, to operate with low noise and to be inexpensive to manufacture. For this purpose, the output drive shaft (6) of a drive (5) composed of an electric motor (17) and a gear mechanism (18) is connected to a drum (7) which is connected eccentrically to said drive. Said drum (7) is inserted in a rolling bearing (9) whose outer raceway (10) acts on a plate (1) of an L-profile. Said plate (1) runs parallel to a further plate (2) which is part of a U-profile which bears the entire device. The L-profile is guided in the U-profile by means of pins (15). Inserted between the plate (1) of the L-profile and a plate (2) forming the web of the U-profile is an elastomeric piece (3) of tubing which is connected to the arrangement of leads in the human dummy forming the arteries. In operation, the L-profile executes a translatory movement against the plate (2) of the U-profile so that the tubing (3) located between them is squeezed periodically to correspond to the rhythm of the pulse. In this case, the pulse frequency can be varied (frequency trigger circuit) as desired by an electronic control gear (frequency former).   The dummy can be used, in particular, for first-aid courses. <IMAGE>

Title: Sewing machine photoelectric device - to control arrest position of stitching elements
IPC: D05B69/24
Filed: 1972-10-04
Granted: 1973-05-18
Abstract: A sewing machine has a number of pref. transparent discs (of e.g. acrylic resin) mounted on a stub shaft driven by the machine main shaft, and each disc has a portion of its periphery formed with a reflective surface (e.g. polished aluminium film coated with an anti oxidant e.g. plastic). A light source (e.g. photodiode) and photosensor (e.g. phototransistor) are associated with each disc so that when the machine is stopped the photosensors detect light reflected by the reflective surfaces of the discs from respective light sources and e.g. arrest the stitching needle in its upper or lower position and activate a yarn cutting device at a particular time. The angular position of the discs on the stub shaft and therefore the relative angular positions of the reflective surfaces can be adjusted to adjust the arrest position of the stitching needle and the time of operation of the yarn cutting device. The device operates consistently and is unaffected by oxidation of the elements which effects operation of e.g. mechanical or magnetic devices.
