Inventor: DALTON LONADIER FRANK
IPC: B01J2/00
Filed: 1968-10-15
Abstract: Uniform dimension and surface configuration plutonium oxide microspheres. Are prepared by (1) dissolving a Pu compound in acid (pref.

Title: Shuttle-less weaving loom
Inventor: E BELLMORE RAYMOND
IPC: D03D35/00
Filed: 1968-10-24
Abstract: Two fingers introducing the weft are provided, one on each side of the weave, to each of which a weft thread is fed and which move synchronously in their own, although neighbouring parallel planes from a position outside the edge of the weave to a position just in front of the opposite edge of the weave. The finger stroke is sufficiently great to allow the finger ends near the end of their inwardly directed stroke to cross over and, in the other dirction of movement, to lead the fingers out over the edges of the pattern to be woven. Furthermore one needle is provided with a drive which takes the needle upwards at a point near to but not exactly at the end position of the inward stroke of the fingers. During their return stroke both fingers wrap weft thread loops around the needle, to which a securing thread is fed running in the longitudinal direction of the pattern to be woven and below the very top position of the needle, being caught by the needle in its downward movement and drawn in a loop through the two weft thread loops. The needle is provided with a lock preventing the needle from catching other threads when the securing thread is drawn down.

Title: Tinsel type Christmas tree decoration - formed by pulling through V slot to orient projecting fibres
IPC: A41G1/04
Filed: 1973-12-05
Abstract: A device for making "angels' hair" decorations for Christmas trees and the like comprises a heated, stationary grooved disc around which a strand or garland having radially projecting fibres, esp. of thermoplastics, is conducted, so as to orient all the fibres into a V-shaped arrangement. Downstream of the stationary disc the fibres are intermittently pulled by a device comprising a pair of pivoting plates which oscillate longitudinally; during the forward movement, the plates close and grip the garland, then open and return while in the opened position in order to repeat the cycle. Preferably, the garland is fed onto the stationary disc by a guide located relative to the pulling device, in such a way that there is a large angle of wrap around the stationary disc. Upstream of this guide device, there may be a tapering funnel which commences the orientation of the fibres into a tapering arrangement as the strand is pulled through the funnel.

Title: Calcining plant for light expanded clay aggregates - where pellets are tumble dried and fines blown off before calcining
Inventor: BRIEM KARL DIPL ING DR
IPC: F27B7/32
Filed: 1973-12-07
Abstract: Pre-formed pellets of clay aggregate are fed through a drying zone into a calcining furnace for blowing into a light expanded granulate; during their travel through the drying zone, the pellets abrade each other to form smooth, round surfaces, and the hot gas from the furnace is utilised in a separator between the dryer and the furnace to blow the fine abraded particles off the pellets. The pref. plant uses a horizontal rotary drum dryer and a horizontal rotary drum furnace, and the separator consists of a chute designed to remove the fines, and a shutter is provided to regulate the gas flow through the separator. The fines are prevented from entering the furnace so the process may be operated continuously over a long period without deposits forming in the calcining furnace.

Abstract: The optical waveguide has an electro-optical, light-transmitting crystal body and several spaced electrodes on the same surface of the crystal. The electrodes form one or more pairs of adjacent electrodes. They define a crystal zone which acts as waveguide for the light waves to be guided when a given voltage is applied between the electrodes of the pair. The two electrodes (50, 51) of the pair diverge from each other. The crystal zone (52) between the two electrodes (50, 51) is of a different width at one end of the waveguide than at the other. The electrodes form two additional pairs (44, 45; 47, 48) of parallel electrodes.

Title: Resistance compensation by variable negative resistance - uses circuit which compensates for losses in electronic switches whose ohmic resistance and impedance differ
Inventor: GASSER LORENZ
IPC: H03K17/06
Filed: 1974-04-22
Abstract: An electronic switch, a variable resistance and a source of alternating measuring current are connected in series to form a circuit. As signal to be transmitted is introduced into the circuit by convenient coupling elements, for example by transformers, a constant gain amplifier is provided at the exterior of the circuit to amplify the signals. The transformers are shunted by first isolating networks which give an open circuit to the frequency range of the signal and a short circuit to the frequency of the alternating measuring current. The alternating current source is shunted by a second isolating network which gives a short circuit for the frequency range of the signals and an open circuit for the measuring current frequency. The circuit has a control and comparison circuit which adjusts the variable resistance so that the total resistance of the circuit takes a constant predetermined value.

Title: Two way valve with soft elastic ball valve - which is pressed against its seat by a second ball running over a cam face
Inventor: FREI WALTER
IPC: F16K1/14
Filed: 1974-04-26
Abstract: The valve is used as pneumatic or hydraulic switch and consists of a cylindrical valve body into which a radial hole is drilled. One small diameter hole connects centrally with this hole, a second small hole connects to the side of the radial hole. The small holes form in and outlet holes for the fluid or gas. Two balls are mounted in the radial hole, the bottom one is made from a soft elastomer and acts as a valve which sits on the central hole. The second ball lies on top of the first one, is made from a harder material and engages with a cam face in ring which surrounds the cylindrical valve body. The cam will depress the top ball when the ring is rotated. A disc is mounted between the two balls. The disc has a part spherical depression which fits over the elastomer ball and reduces the amount of compression of this ball.
