IPC: C08G63/58
Filed: 1968-12-27
Abstract: A polyester derived at least in part from an [alpha],# - unsaturated, cis - configuration dicarboxylic acid is isomerized into the trans-configuration by (a) adding a compound of the formula where each of R 1 to R 4 is hydrogen or a C 1-5 alkyl group to the polyester, preferably in an amount of 0À01 to 5% by weight based on the polyester and (b) heating the mixture at 15- 110 C. until at least a portion of the polyester has been isomerized. Isomerization may be effected in the presence of a solvent and styrene. In the examples, the polyesters were derived from (1) and (2) maleic anhydride, fumaric acid, phthalic anhydride and propylene oxide (4) maleic anhydride and pentanediol (6) maleic anhydride and propylene oxide.

Title: Production of a fancy yarn
IPC: D04H3/009
Filed: 1970-05-08
Abstract: A process for producing a fancy yarn having a homogeneous distribution of the fibre length between staple length and continuous portions comprises producing a fleece by depositing continuous filaments in a statistically random fashion on an endless belt moving at constant speed, at least temporarily strengthening the fleece e.g. by the addition of a binder, and cutting the fleece into continuous strips, the strips being twisted to produce a fancy yarn. In a preferred embodiment, threads 1 are drawn from a creel and opened into the individual filaments 3 by air jets 2 prior to being deposited on an endless belt 4. A watersoluble binder is sprayed on to the fleece at 6 and the strengthened fleece 5' is cut into strips 8 by knives 7. The strips 8 may be pulled between pairs of rolls 9 and 10 prior to being twisted on a ring twisting machine. The threads 1 may be of different colours and at least two strips of different colours may be twisted together to form the yarn. In a further embodiment, the strengthened fleece is wound on a support and the resultant package is cut into discs which are twisted to form the yarn. When the fleece is temporarily strengthened by means of a water-soluble binder, the binder may be washed out of the yarn.

Title: Method and devices for forging single crank throws of semi-built up crankshafts
IPC: B21J5/00
Filed: 1976-03-15
Abstract: A method and an apparatus for forging single crank throw elements comprising upsetting a rough piece in a ring-segment compression die to form a blank having opposite shoulder portions with a narrowing connection portion, the connection portion narrowing from both shoulder portions to a central narrowest section. The blank is placed in a die with the shoulder portions resting against inclined surfaces of the die such that clear spaces are formed between the shoulder portions and the inclined surfaces. A force is applied against the narrowing connection portion in a direction perpendicular thereto to deform the narrowing connection portion in a direction to fill the clear spaces while concurrently upsetting forces are applied to the shoulder portions in a direction perpendicular to the direction of the force applied to the connection portion. The upsetting forces are applied by laterally driving die holder elements towards one another by an inclined wedged element which is driven by a press. The die holder elements are supported by articulated links pivotably mounted on fixed structure.

Patent ES-463140-A1 (ES)
Title: Bubble detector
IPC: G01N22/02
Filed: 1977-10-11
Abstract: The bubble detection system has a detector. This detector has a transmitting (4) and receiving elements (5). The receiving element (5) receives radiations emitted by the transmitting element. The system has means (2) for maintaining a section of the pipe (1) (tube), to be survelled, between the transmitting (4) and receiving elements (5). A detection circuit (8) connected to the receiver (5) produces a signal whose level is a function of the radiation level collected by the receiver. A detection signal variation circuit has a memory which receives the detection signal. This memory only retains the value of the signal if it remains constant during a predetermined time. This time is longer than the passage time of a bubble between the detection elements. The predetermined time is less than a certain value. This permits the system to adapt itself to progressive changes in the properties of the liquid in which bubbles are to be detected.

Abstract: The dishwasher contains a drainage trough (2) in the base of the wash container (1) which has a sieve (7, 8, 10) and a connecting pipe (3) for the circulating and emptying pump (4) and a level regulating device containing electrodes (12, 13) which are located in a small-volumed vessel (11) set outside the wash container at the normal and safety level (15, 16). The vessel (11) is connected to the wash container by a branch pipe (17) which is connected offset to the connecting pipe (3) of the circulating pump (4) in the drainage trough (2) whilst a ventilation opening (19) is provided at the top of the vessel (11). Since the electrodes (12, 13) are located outside the wash container, they are separated from the circulation system and owing to the branch pipe, the level regulating system functions properly even with a low water level in the wash container.

Title: Method and apparatus for individual control of injection mold shut-off bushings
IPC: B29C45/00
Filed: 1979-10-26
Abstract: A method and apparatus for multiple cavity injection molding which permits individual variation of gate opening time for mold shut-off bushings. The gate pins for the shut-off bushings are controlled by individual double-acting fluid motor, the bushings being fed by a common manifold. Gate opening is thus not dependent upon attainment of a predetermined injection pressure. Closure of the gate for each cavity will permit material to be fed faster to the other cavities. Novel means is provided for securing each gate pin to its actuating cylinder, which minimizes heat transfer to the motor, accommodates expansion of the material manifold and permits gate opening adjustment. The fluid motors are end-mounted on an actuating fluid manifold, allowing close juxtaposition. A cycle counter may be used to control inventory.
