Title: Apparatus for recording and reproducing telephonic messages
IPC: H04M1/65
Filed: 1921-01-10
Abstract: 157,321. Medico, M. de. Oct. 31, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Manual exchange systems.-The act of removing the telephone from its hook starts a motor by which a sound - recording - machine is driven, the movement being stopped when the receiver is replaced. In the absence of the subscriber, the hook may be lifted automatically, and the message recorded, the motor being allowed to run by a time-switch for a predetermined length of time. Fig. 2 shows the general arrangement of the motor-circuit. When the arm C is on the stud 5, and the telephone receiver is lifted, contact is made at 1, 2, and the motor M starts, driving the phonograph to record the conversation until the receiver is returned. For reproducing purposes, contact is made upon the stud 3. A cylinder or disc machine may be employed, the recording sound-box being actuated by the voice currents. The reproducing soundbox is fitted with a flexible ear-tube. For recording a message when the subscriber is absent, an escapement 22, Fig. 6, operated by or in connection with the call-bell 20 is employed to complete a circuit through a switch 24 which keeps the telephone hook raised for a period determined by a timing device. During this period the motor keeps the sound-recording machine running to take down the message.

Title: Method for the manufacture of new adsorbents and adsorbents obtained by the said method
Inventor: KADOIKE MASAO
IPC: C08J3/21
Filed: 1964-01-14
Abstract: Granular adsorbents are made by kneading a mixture of finely divided carbon with a solution of a cellulose ester or a synthetic resin in a volatile solvent to form a plastic mass, shaping the plastic mass into granular form by mechanical means, and heating the granules to remove the volatile solvent and harden the granules.  The temperature may be within the range 100 DEG  to 300 DEG  C. The heating may be sufficient partially to carbonize the polymeric binder material.  The free carbon may have a pH of 5 to 7 and may be carbon black or carbon formed as a by-product in the manufacture of hydrogen by pyrolysis of hydrocarbons, and having a particle diameter of 150 <\>rA to 200 <\>rA. The cellulose derivative may be cellulose acetate and the synthetic resin may be polyacrylonitrile. The solvent may be methanol containing a minor proportion of acetone, methylene chloride, chloroform, dioxane or dimethyl formamide.  The solution of the cellulose derivative or synthetic resin may have a concentration of 4 to 10% and the proportion of carbon may be 28 to 34% and of solution 72 to 66% in the plastic mass.  The mixture may also contain finely divided silica, e.g. silica gel, or alumina or alumina-silica, preferably of particle size 600 <\>rA to 700 <\>rA, the ratio of carbon to silica being 65 to 75% of carbon to 35 to 25% of silica. In an example, 100 grams of byproduct carbon black having a particle diameter of about 200 <\>rA is kneaded at 20 DEG  to 25 DEG  C. with a 4 to 10% solution of cellulose acetate in dimethyl formamide, the proportion of cellulose acetate in the mixture being 15 to 17% that of the carbon black, the resulting plastic mass is formed into granules and maintained at 100 DEG  to 120 DEG  C. for about 30 minutes.  In another example, 82 grams of finely divided free carbon are mixed with 180 c.c. of a 10% solution of polyacrylonitrile in dimethylformamide.  The granulated mixture is passed through an oven having a temperature gradient of 100 DEG  to 300 DEG  C., the residence time of the granules in the oven being about 2 hours.

Synthetic (e.g. polyacrylonitrile) and woollen fibres are first heated at 200-350‹ C. in an oxidizing atmosphere. Such fibres or natural fibres (e.g. cellulose) are then carbonized by heating at 850-1100‹ C. in a reducing or inert atmosphere. Optional graphitization is achieved at 3000‹ C. in an inert atmosphere. The binding carbon is added by addition of suitable synthetic resin (e.g. of furan, phenol-formaldehyde epoxy or acrylic, with hardeners, e.g. benzene sulphonic acid, maleic acid, oxalic acid or metal halides) in alcohol solution to the fleece or felt and hardened. The fleece or felt may be carbonized first or at the same time as the resin. Alternatively the carbonized or graphitized fleece or felt is heated in an atmosphere containing a hydrocarbon (e.g. propane) at 800- 1600‹ C under reduced pressure (1-500 mm. Hg). The layer of carbon is from 0À8-1À5 Á thick. The synthetic resin taken up is from 30-100 parts per 100 parts by weight of the fibre body.

Abstract: 1524916 Determination of aryl hydrocarbon hydroxylase MASSACHUSETTS INSTITUTE OF TECHNOLOGY 16 May 1977 [24 May 1976] 1918/78 Divided out of 1524915 Heading G1B [Also in Division C3]  An enzymatically active supernatant, particularly useful in evaluating the mutagenesis of tissue cells cultured in vitro, is produced by the steps of homogenizing mammalian tissue e.g. rat liver, in an aqueous suspension medium, removing relatively large particles to produce a post-mitochondrial supernatant, and filtering the post-mitochondrial supernatant with a filter having a pore size sufficient to remove contaminating bacteria e.g. from 0.22 to 0.3 micron pore size. To the supernatant there may be added from 0.25 to 1.0 micromoles per millilitre of nicotinamide adenine dinucleotide, oxidized form (NADH). The aryl hydrocarbon hydroxylase activity (AHH) of the supernatant product is determined by incubation with benzopyrene followed by fluorimetric evaluation of the 3-hydroxy benzopyrene product. Examples demonstrate that the AHH activity is considerably increased by the bacterial filtration of the supernatant and the (optional) addition of NADH.
