Title: Improvements in and relating to the manufacture of sponge rubber
IPC: C08L21/00
Filed: 1944-01-18
Abstract: In making sponge rubber by heating foamed latex compounded with ingredients for vulcanization and, if desired, with fillers such as China Clay or whiting and pigmenting ingredients, there is incorporated into the latex before foaming a preparation comprising a dispersion of a wax-like higher fatty acid, e.g., stearic acid, in an aqueous solution of a soap thereof, and the foamed latex is heated to a temperature at least as high as the m.pt. of the fatty acid. Preferably, a soap of a volatile base, e.g., the ammonium soap, is employed.  The preferred amount of fatty acid is 3-4 per cent. of the dry rubber content.  The preparation may contain a phosphatide, e.g., lecithin, as a dispersing agent, a cationic soap, e.g., dodecyl-trimethyl-ammonium bromide or cetyl pyridinium bromide, methyl cellulose or a substance dispersing similarly in water, and a softening agent for rubber which contains fillers, e.g. thin lubricating oil, liquid paraffin or petroleum jelly.  The heating is preferably effected with progressive increase in temperature, e.g., by passage of moulds filled with foam in 1-1 1/2 hour through compartments rising in temperature from an entrance temperature of 80 DEG C to an exit temperature of 120 DEG C., drying being then completed at 80 DEG C.
Patent GB-835643-A (GB)
Title: N-aryl-n'-alicyclic-para-phenylene diamines
IPC: C08K5/18
Filed: 1958-01-10
Abstract: N - aryl - N1 - alicyclic - p - phenylene diamines are prepared by reducing an anhydrous Schiff base obtainable by the reaction between an N-aryl-p-phenylene diamine and an alicyclic ketone.  The Schiff base may be prepared by reacting, for example, N-phenyl-p-phenylene diamine with at least 3, and preferably 4, mols of ketone and azeotropically distilling off the water of reaction with the excess ketone or with an added solvent such as benzene.  The reaction may take place below atmospheric pressure so that the Schiff base is formed at a reaction temperature of about 90 DEG  C.  The reduction may be carried out with hydrogen in the presence of nickel in the presence of the excess ketone as solvent or the excess ketone may be distilled off and the dry Schiff base dissolved in another solvent such as methanol, benzene or isopropanol.  Ketones such as cyclohexanone and alkyl and polyalkyl cyclohexanones having at least 1 ortho position unsubstituted and 1 to 5 carbon atoms in the alkyl group may be used and cyclopentanone may be used to give the novel compound N-phenyl-N1-cyclopentyl - p - phenylene diamine which is claimed per se.  In the examples, N-phenyl-N1-cyclohexyl-p-phenylene diamine is prepared (1) by forming the Schiff base at 88 DEG  C. from N-phenyl-p-phenylene diamine and excess cyclohexanone in the presence of benzene, tranferring the whole mixture to an autoclave and hydrogenating at 130-150 DEG  C. for 1.5 hours at 300 lb./sq. in. in the presence of nickel; (2) as in (1) where 4 mols. of cyclohexanone are used and the solution is diluted with benzene prior to hydrogenation; (3) as in (1) where the excess cyclohexanone is distilled off and the Schiff base dissolved in 2-propanol prior to hydrogenation; (4) the N1-cyclopentyl compound is prepared in a similar manner using cyclopentanone.

Patent HK-76595-A (HK)
Title: Identity card and its production method
Inventor: HOPPE JOACHIM
IPC: B42D15/02
Filed: 1995-05-18
Abstract: An identity card, e.g. a cheque card or credit card, usually has a space in which the card user writes his signature when the card is issued. A weak point, as far as manipulations of the cards are concerned, has long been that the signature space could be eliminated and replaced by a counterfeit signature space. According to the invention, in order that such manipulations are easily recognisable and forgeries are consequently made more difficult, the security typography (guilloche print) which anyway covers the area surrounding the signature space is extended on without transition over the signature space also. If the counterfeiting of a signature space provided with such security typography is itself extremely difficult, it is practically impossible to arrange the security typography in such a manner that it passes continuously from the signature space into the area surrounding the signature space. <IMAGE>

Title: Adaptive quantizer
Inventor: YONEZU YASUNORI
IPC: H03M7/38
Filed: 1987-01-07
Abstract: PURPOSE:To transmit modem signals at 9,600bps by varying a threshold used for the decision of the difference between a short time average of quantization value and a long time average of the same by using the difference between the two time average. CONSTITUTION:In case an input signal is a data modem signal, since distribution of quantization values I(k) is narrow,, the difference between the long time average value and the short time average value of values F(I(k)) representing the magnitude of a predicted remainder signal is highly likely to be small, and a comparison constant alpha becomes larger. Therefore, a speed control parameter a1(k) approximates to a1(k)=0 for data modem. On the other hand, in case of a voice signal, since variation in the quantization values I(k) is wide and said difference between the long time average value and the short time average value is highly likely to be large, and the constant alpha becomes smaller, the process is inverse to the case of a data modem signal, hence the speed control parameter a1(k) approximates to a1(k)=1 used for voice. In such a way, the speed control parameter a1(k) can be generated suitably for an input signal, and thus a transmission with 9,600bps modem is made possible.

Abstract: PURPOSE:To obtain an end face of excellent mirror surface without spoiling the optical charactlristics, by removing the polymer clad layer of polymer clad optical fiber, forming a silver film on the surface of exposed fiber core, securing, cutting, and polishing the cut surface. CONSTITUTION:A clad layer 2 and a sheath 3 which surround a fiber core 1 of a polymer clad optical fiber are removed mechanically and chemically, and a silver film 4 which is dense, high in hardness and excellent in adhesion is uniformly formed on the core 1 by brushing or other method. This core is secured to a metal or glass sleeve 5 with fixing agent (epoxy resin or the like) 6, and is further secured with a fixing member 7 having a similar hardness as the corl 1, and is then cut  along line A-A together with the member 7. Thus produced end face is finished to  mirror surface. Since it is secured with the silver film 4 of high hardness, the end  face is free from loss or deviation, and the light is reflected by the silver film 4 not leaking to outside, so that splicing of optical fibers or splicing of optoelectrical  transducers may be achieved excellently.

Title: Fault detection and fault recovery method in ring type lan
Inventor: OBA TOSHIMITSU
IPC: H04L12/42
Filed: 1990-01-08
Abstract: PURPOSE:To detect a logic fault quickly and to recover the fault automatically by discriminating it as the occurrence of a fault when the reception of a fault notice frame is being continued, separating all stations connecting to itself and integrating only normal stations to a loop. CONSTITUTION:A line concentrator 12 detects a fault when a fault notice frame from other station is received for a prescribed time or over and all single attachment stations 13 under the control are separated when the fault notice frame is sent for a prescribed time or over to detect a fault. In this case, an automonous bypass flag attached to each station is set and the fault is recovered so that the separation is not released so long as the flag is not reset. After all the single attachment stations 13 under its control are separated, the separation is once released sequentially from the upperstream side and the stations are integrated in a duplex loop to conduct the test and only the stations not normal are again consecutively separated. Thus, faulty stations are detected from all the stations and the fault recovery is automatically implemented.
