Title: Process for the production of polyhydantoin plastics containing imide groups
IPC: C08G73/10
Filed: 1968-08-07
Abstract: Laminates may be prepared having as one of the layers a polyhydantoin plastic containing imide groups prepared by reacting, in a first stage, a polyfunctional glycine ester derivative containing at least two glycine ester groupings and having the formula wherein R is an n-valent aliphatic, aromatic or araliphatic radical, each R 1 represents hydrogen or an alkyl radical, R 2 represents a hydroxyl, amino, alkylamino, dialkylamino, alkoxy or aryloxy group, R 3 represents hydrogen or an alkyl, aralkyl or aryl radical and n represents an integer from 2 to 4, with an excess of a polyisocyanate or masked polyisocyanate (based on amino groups in the glycine ester derivative) to form a preadduct containing hydantoin and urethane and/or urea groups, and in a second stage, reacting the preadduct with a polyfunctional compound containing at least one cyclic carboxylic acid anhydride group and at least one additional group capable of undergoing a condensation or addition reaction with isocyanate, urethane or amino groups in the preadduct, the reactions being effected in an organic solvent at 20 to 500 C. The polyfunctional compounds will preferably contain several cyclic anhydride groups or at least one cyclic anhydride group and additional carboxy, hydroxyl or NH-groups in the molecule. In a typical example N,N1 - bis - (carbomethoxydimethylcarbinyl) - 4,41 - diamino diphenyl methane is reacted with excess diphenylmethane 4,41 - diisocyanate to form a polyhydantoin oligomer which is reacted with pyromellitic acid dianhydride in cresol. The imide-modified polyhydantoins are suitably applied under pressure to glass fibre-, silk-, or asbestos cloths to obtain laminates.

Title: Method of constructing marine float structures
IPC: B63B9/00
Filed: 1970-06-04
Abstract: A method of constructing a marine float structure, such as a large-sized ship structure, is accompolished by assembling a number of divided ship portions on a ship building base. The first divided portion is transported on the water surface by means of a composite pontoon which is so constructed that each individual portion thereof can be separated from the other up and down or forwardly and backwardly. Then the composite pontoon is caused to sink down in the water so that said first divided portion of the ship can float of its own accord on the water surface. Subsequently the second divided portion of the ship is transported on the water surface using the same pontoon as mentioned above. A part of the composite pontoon is separated from the remaining body and allowed to sink down in the water while said second divided portion of the ship is held by the remaining portion of the pontoon. The separated part of the pontoon is used to float said first divided portion of the ship on the water surface, thereby combining both divided portions of the ship in a single unit on the water surface.

Title: Ignition distributors
IPC: F02P7/06
Filed: 1970-08-08
Abstract: A method of assembling an ignition distributor of the kind which includes a base plate which is secured to the casing of the distributor and a timing plate which is mounted for angular movement on the base plate includes the steps of engaging a first annular plate with an annular base plate so that three projections provided on the first plate extend through corresponding apertures in the base plate. The three projections of the first plate are so disposed that any one of the projections is on the opposite side of a diameter of the first plate from the remaining projections. The portions of the projections which extend from the base plate are then subject to a levelling operation so that the free ends of the projections lie in a common plane parallel to, but above the plane of the base plate. A third annular plate is then engaged with the free ends of the projections where they extend from the base plate, and resilient means is utilized to couple the first plate and the third plate to define an assembly. The resilient means urges the third plate towards the first plate, and the first or third plate includes a cylindrical spigot which extends through a hole in the base plate, so that the assembly of the first and third plates is movable angularly relative to the base plate. Either the first plate, or the third plate constitutes the timing plate of the distributor in use, and carries the contact breaker assembly of the distributor.

Title: Method and apparatus for texturizing yarn
IPC: D02J1/00
Filed: 1971-08-13
Abstract: A method of producing an intertwined yarn of predetermined opening length, i.e. distance between points of intertwining, comprises passing a yarn through a jet of medium directed substantially perpendicularly to the yarn and thereafter flowing freely away, and subjecting the yarn to fluctuations in tension. The frequency of the fluctuations is given by n=w/l where n= the number of cycles of fluctuations in tension per minute, w= the rate of travel of the yarn in metres per minute and /= the required average opening length in metres. In a preferred embodiment, the yarn 4 .is passed to the nozzle 9, supplying the jet of medium, via two guides 5 and 6. The fluctuations in tension are produced by means of a pin 8 mounted on a rotating disc 7. Alternative means for producing the fluctuations in the yarn tension comprise an electromagnetic yarn brake, or a vibrator of adjustable frequency. The initial pressure of the air used as the jet medium is 2.5 to 5 atmospheres, preferably 3.2 to 4.2 atmospheres. The yarn tension fluctuates between a lower value of 0.02 to 0.18 lbs./ denier and an upper value of 0.4 to 0.8 lbs/ denier. The lower value of yarn tension is preferably in the range 0.04 to 0.15 Ibs./denier and the upper value is preferably in the range 0.45 to 0.63 Ibs./denier. The average frequency of the fluctuations in yarn tension is from 2000 to 10,000 per minute, preferably 5000 to 8500 per minute. Air or steam may be used as the jet medium.

Patent ES-410792-A1 (ES)
Title: Alarm apparatus for facilitating the detection of an unauthorized removal of property
IPC: G08B13/24
Filed: 1973-01-19
Abstract: An alarm packet of simulated paper currency contains alarm means and alarm-operating circuitry such that, when the packet is removed through an exit irradiated with a local field, the alarm means will thereby be automatically actuated to produce an alarm, as by the release of smoke, tear gas, or staining materials, or by producing alarm sounds, etc. Such a packet is placed with the currency given to a bank robber, and facilitates his apprehension and/or recovery of the loot. The electrical circuitry for actuating the alarm is constructed to prevent operation of the alarm until the packet has been taken into the local field and removed therefrom, so that it will not operate if the robber lingers in the exit area within the field. Preferably the removal of the packet from the local field initiates a timing cycle for further delaying actuation of the alarm means, and provision is made so that if the packet is returned to the local field at the exit before the timing cycle is completed the alarm means will not be actuated and the timing cycle will be reset. The field is preferably an alternating magnetic near-field radiation having a frequency of less than about 3,200 Hz, the preferred frequency range being about 400 to about 1,600 Hz.

Title: Automatic change-over device for liquid dispensing system
IPC: B67D1/00
Filed: 1977-01-21
Abstract: An automatic change-over system for stock rotation of liquids packaged in plural collapsible bag-type reservoirs is described. The bag-type reservoirs are divided into primary and secondary groups, the primary group containing the supply of liquid being dispensed and the secondary group containing the liquid supply held in reserve. Automatic change-over between the primary and secondary groups of bag-type reservoirs is effected in response to a vacuum created by the empty condition in the bags in the primary group. The pressure change in the present system is the result of the deflation of the empty bag-type packages. Thus, the change-over is caused by the characteristics of the flexible bags containing the liquid being dispensed.
