Abstract: A viewer discretion television program control system including devices and methods for controlling access to television viewing, especially by children. It includes provision for storing suitability ratings for each program receivable by a television set, allocation of personal identification numbers to each of a plurality of potential viewers (e.g., children), and individual allocations of permissible viewing time and program content, all under the control of a local authority such as a parent or guardian.

Abstract: A skin treatment process designed to reduce the aging process of the skin and to cause the skin to become a semi-permeable membrane. The steps include exfoliation, cleansing, hydration, and oxygenation. By placing solutions ranging from a pH substantially in the range of 4.5 to 8.8 on the skin in a predetermined order, the skin will be able to accept a oxygenated mist of moisturized nutrients on a pore-by-pore basis.

Abstract: A tape loader has a splicing station including a splicing block whose underside is grooved and provided with perforations constituting vacuum shoes. A slitting head mounts a blade which cooperates with the grooved under surface in slitting tape across its lateral dimension while it is received in its groove retained by vacuum. A splicing arm operates through an orifice in a face plate to splice together two lengths of tape retained in the groove. Operating on the front face of the face plate is a final guide assembly comprising an eccentric plate having a leader tape extraction arm; a bearing block housing a journal into which a cylindrical boss, integral with the plate, is rotatably received; and an internal flange of the boss forming a tooth wheel operably with a belt to apply the output of a motor to drive the plate. The changeover arm is comprised of a cranked changeover arm member mounted to a sleeve secured to a shaft passing through an orifice in the face plate.

Abstract: 7.beta.-Amino-3-hydroxy-1-carba(1-dethia)-3-cephem-4-carboxylic acid esters are provided via cyclization of cis-3-(substituted amino)-1-(2-substituted 2-oxoethyl)-4-substituted azetidinones. The 7.beta.-amino-3-hydroxy-1-carba(1-dethia)-3-cephem-4-carboxylic acid esters are useful chiral intermediates to .beta.-lactam antibiotics.

Abstract: Provided is a process for isolating cefaclor from an acylation reaction mixture by adding anthraquinone-1,5-disulfonic acid to the mixture. The acid highly selectively precipitates with cefaclor so that isolation and recovery is streamlined.

Abstract: Open spool reels (18) of magnetic tape (7) are recorded with a plurality of different programmes interspersed with recordings in a different form (typically as interruptions to the sync track), representing data information concerning the programme material and production history of the recording. The data (6) recorded on the tape (7) is read by a transducer (39) on a cassette loading machine (30) and used to control the operation of the loading machine, identifying the length of tape and the position on the tape where splices between the magnetic tape (7) and leader tape in cassette shells is to be made. The data (6) also controls a label printer (46) to produce a printed label, typically in bar code form, carrying information representing the programme material on the tape loaded into the cassette.

Abstract: A conventional video recorder has a top plate 2 mounting a tape supply spool 22 and tape take-up spool 22a upon a common shaft 19. A recording assembly 6 has a conventional video recording drum and combines with a master cassette holder 4 to complete a cassette recording station. A roller system guides the tape from the supply spool 22 through the recording station to the tape-up spool 22a. Stepper motors 3 provide rim drive to the the spools 22 and 22a and vacuum troughs 8 and 9 and associated photoelectric devices provide for speed control of the tape transport functions as a whole to ensure that tape is conveyed at a uniform speed without slack.

Abstract: Apparatus for loading use tape (e.g. magnetic tape for video recording and playback) into leadered (e.g. V-zero) cassettes comprises a stationary splicing head 3 having an undersurface provided with a tape-receiving groove 4. A pair of vacuum shoes 5 and 6 serve to retain tape releasably in the groove and are connected to a vacuum source within the casing of the apparatus. A slitting head 7 operates from an internal pneumatic power source on shaft 9, the blade 8 of the head 7 running in a slot traversing the groove 4. In use, leader tape 20 is extracted from the cassette by leader extraction arm 18 and lift arm 19 and disposed in the groove 4. Slitting head 7 then operates to slit the tape into two lengths retained in groove 4. Use tape 26 previously placed in groove 4 and cut so that end 27 thereof is adjacent the groove for the blade 8 is sandwiched against the head 3 by the leader tape. Lift arm 19 and extract arm 18 then lower, the right hand end of the leader tape exposing the use tape in the groove.

Abstract: Crystalline p-nitrobenzyl 7.beta.-phenoxyacetylamino-3-hydroxy-1-carba(dethia)-3-cephem-4-carboxylat e and the crystalline mono-acetic acid solvate thereof are provided by mixing a carboxylic acid or a sulfonic acid with a solution of the 3-hydroxy ester in DMF or DMAC. Acetic acid provides the crystalline acetic acid solvate while other acids provide crystalline non-solvated 3-hydroxy ester. The crystalline forms are useful purified intermediates to antibiotics.

Abstract: A method and apparatus for reproducing magnetic recordings of digital data information particularly on flexible plastics discs known as "Floppy" discs. Data information is copied from one disc to another regardless of the encoding of information and the format of the disc without data corruption upon track changing by the recording transducer, it being unnecessary for the copier to react in any way to the data information in order to identify the buffer zones at which track changing must take place.
