Title: Medical adhesive and method for using the same
Inventor: KONNO MASAYUKI
IPC: A61L15/58
Filed: 1998-01-05
Abstract: PROBLEM TO BE SOLVED: To provide a medical adhesive and a method for using the adhesive which has an excellent adhesion strength to the skin surface and which can be removed from the skin surface without stimulating the skin as the adhesion strength is nearly vanished when the adhesive is removed. SOLUTION: The skin surface contact base layer of this medical adhesive is made of a wet adhesive whose adhesion strength is effective by the contact with water or a hydrophilic medium, and the base layer is formed on one side or both sides of a moisture-permeable base material. As the hydrophilic medium, disinfectant alcohol or ethanol is preferable. And as the wet adhesive, such polymeric materials as polyvinyl pyrrolidone, polyacrylic acid and salt thereof, polyacrylamide, carboxymethylcellulose and salt thereof, etc., mixed with a liquid plasticizer a filler are suggested. When the adhesive is removed, water or a hydrophilic medium is supplied to the skin surface contact base layer through the moisture-permeable base material, so the aggregation and the adhesion strength of the adhesive are reduced.

Abstract: A system for reproducing in a descrambler of a subscriber communication network a subscriber key signal that is unique to the descrambler and was used in encrypting a key signal that must be decrypted for use in descrambling a signal received by the descrambler. The scrambled signal is received by the descrambler together with the encrypted key signal and a key generation number containing an address for accessing a predetermined area in a memory contained in the descrambler. The system includes a circuit for providing a subscriber key generation signal that is unique to the descrambler; a subscriber key generator for reproducing the unique subscriber key signal by processing the subscriber key generation signal in accordance with a predetermined encryption algorithm upon the algorithm being keyed by a prescribed subscriber key seed signal that is unique to the descrambler; a secure memory storing a plurality of different subscriber key seed signals, and for providing the prescribed seed signal to key the algorithm when the area of the memory containing the prescribed seed signal is accessed by the address contained in the received key generation number; and a circuit for accessing the first memory with the address contained in the received key generation number. The subscriber key generation signal is formed by combining the received key generation number with a unique subscriber address signal that is stored in a second memory of the descrambler.

Title: Improved process for the manufacture of acrylic and methacrylic acid esters
Inventor: KOWOLIK ERNEST JAN
IPC: C07C69/54
Filed: 1958-01-07
Abstract: Acrylic and methacrylic acid esters of the formula CH2=CR-COOR1 in which R is hydrogen or methyl and R1 is alkyl, are obtained by removing hydrochloric acid from an ester of the formula Cl-CH2-CH(R)-COOR1 by heating the latter with an anhydrous alkali metal carbonate, e.g. sodium or potassium carbonate, in the presence of an anhydrous polar solvent free from groups which set up undesirable side reactions at such a temperature that the acrylic or methacrylic acid ester is distilled off as it is formed, the amount of anhydrous alkali metal carbonate used being at least equal to that necessary to combine with the liberated hydrochloric acid. Several types of polar solvents are specified including amides, lactams, nitriles, solvents containing OH groups, e.g. ethylene and propylene glycols or other alcohols, dialkyl cyanamides, lactones, cyclic carbonates, cyclic sulphites and cyclic sulphones, e.g. sulpholane, sulphoxides, cyanohydrins, alcohols, nitro alcohols, polyols, nitro compounds, e.g. nitrobenzene, alkyl sulphates, alkyl phosphites or phosphates, N,N-dialkylamides of phosphonic, phosphoric, or pyrophosphoric acids, thiocyanates, dithiocyanates and ketones; mixtures of such solvents may also be used.  The amount of anhydrous alkali metal carbonate may be equal to or in excess of the theoretical amount and a polymerisation inhibitor such as hydroquinone should preferably be present.  Suitable reaction temperatures are from 160 DEG C. to 240 DEG C.  The major portion of the solvent used can be recovered for re-use in the process, e.g. by vacuum distillation after distillation of the acrylic ester is complete, or by filtration from the solid alkali metal chloride with occasional distillation as required.  Examples are given for the production of methyl acrylate from beta-chloropropionate using dimethyl formamide, N-methyl pyrrolidone, acetamide, adiponitrile, ethylene glycol and nitrobenzene, respectively, as solvent, and for the production of the ethyl acrylate from ethyl beta-chloropropionate using dimethyl formamide as solvent.  The process is carried out in each case in a flask fitted with a Vigreux column, condenser and receiver.  Specification 351,518 is referred to.

Magnetic sound recording and/or playback apparatus is controlled by non-locking press-toactuate switches arranged to operate control solenoids through electronic or electromechanical means. As described, a language laboratory comprises a number of student booths, Fig. 1 (not shown), each including a desk with a magnetic tape recorder situated under a removable panel on the desk. The tape has two tracks and one track can play back a lesson whilst answers are recorded on the other track. Individual control circuit.-The controls at each student unit comprise six non-locking, single-make, touch button switches (20-25), Fig. 2, not shown), for controlling respectively re-winding of the tape, playback, recording, fast forward wind, stopping of the recorder, and calling of the tutor. The play and record switches (21) and (22) trigger respective transistor bi-stable circuits (45) and (38) which switch on respective amplifiers and trigger a bi-stable circuit (48) which energizes a solenoid controlling the capstan. When circuit (45) is in its normal off state, an intercommunication amplifier is energized so that the student can talk to the tutor. Triggering of either circuit (45) or (38) restores the other to its normal off state. The re-wind and fast forward wind switches (20) and (23) open respective gate circuits (60) and (61) as long as the switches are closed. Circuits (60) and (61) cause energization of respective solenoids energizing the required drive, and on release switch the apparatus to the playback mode and inhibit'operation of the capstan for a short period to allow the tape to slow down. The call switch (25) operates a bi-stable circuit (54) which energizes call lamps at the student's desk and at the tutor's console. The system may include photo-electric means for sensing the ends of the tape and stopping the tape to prevent it unwinding from a reel. Master control circuit.-The tutor's console includes switches (100-104, Fig. 3, not shown), which control his own recorder and switches (107-111) which can be used to take over control of one or a group of students' recorders according to the positions of switches (116) and (121). Means are also provided for switching different sources of programme material to the students' recorders, for listening-in to a student's recording, and for intercommunication with a student. A memory unit (190) for each student unit enables selected student units to be maintained in the record mode whilst other units are operated in other modes.
