Title: Improvements in telephone systems
IPC: H04Q5/06
Filed: 1931-07-06
Abstract: 365,976. Party line systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. 33. Kungsgatan, Stockholm. July 6, 1931, No. 19409. Convention date, July 26, 1930. [Class 40 (iv).] Subscribers on a party line are selectively called by the connection of direct current of different strength and direction to the line wires, condensers being used in conjunction with marginal polarized relays to provide the necessary pulsating effect. An eight-party line is described, the signalling current being provided by a 120 volt battery connected to earth at its centre point and tapped at + 60, + 30, - 30 and - 60 volts, the tappings being connected to the key set K as indicated in the Figure. If the party 1 is required SK is depressed and key 1 operated. A potential of + 60 is thus connected to the a wire and + 30 to the b wire. This + 60 voltage energizes the marginal polarized relay P and charges X, the circuit being over R and 8 to earth. The operation of P connects X in parallel with H and R and Y charges. Relay H is energized by the discharge current from X and connects Z to the b wire. When Y is fully charged, P can no longer hold its armature and it releases, breaking the circuit of H. Condenser Z discharges and operates the marginal polarized alarm bell PR. P re-energizes and the cycle is repeated. The relays P and H at some of the other stations operate in synchronism with those at station 1, but as PR is marginal and polarized, no other bell is operated. The bell PR may be replaced by selective relay equipment and in an automatic system the key set K may be replaced by a relay set.

Patent GB-612077-A (GB)
Title: Improvements in and relating to the separation of amino acids
IPC: B01J47/00
Filed: 1946-07-01
Abstract: Polyamino acids are separated from mixtures thereof with monoamino acids or with one another by a process wherein an aqueous solution of mineral-acid salts of the acids is passed over a cation-exchange resin to absorb the polyamino acids, which are then recovered from the exchanger, in separate fractions, if desired.  The process is particularly applicable to the recovery of lysine, histidine and arginine from amino acid mixtures obtainable by the acidic and/or enzymatic hydrolysis of proteins, e.g. by the hydrolysis of meat scraps, casein, offal, blood meal, corn and wheat gluten, corn germ meal protein, lactalbumen, hair or keratins with dilute hydrochloric, sulphuric or hydrobromic acid.  Suitable exchange materials are the sulphonated phenylformaldehyde resins sold under the Registered Trade Mark "Amberlite".  In practising the invention, the exchange material is treated with a mineral acid and then (after washing) with a flowing aqueous mineral-acid solution of the amino acid mixture, the treatment being continued until the hydrogen ion concentration of the effluent rises to pH 1.5-3, or until a chemical test shows a substantial increase in the polyamino acid content.  The absorbed acids are then recovered by treating the exchange material with a stronger acid or a base, and this treatment may be effected with different reagents or reagents of different strengths so as to separate the absorbed acid to some extent from one another.  Suitable reagents for this purpose are dilute sulphuric, hydrochloric, hydrobromic or nitric acid of pH 0.6-1 or a dilute solution of a base such as ammonia, methylamine or a mixture of sodium di- and tri-phosphates.  When the changed exchange material is treated with an acid lysine is liberated more easily than histidine and the latter more easily than arginine, and this property may be applied in fractionating the absorbed acids.  Alternatively, for this purpose the changed exchange material may be treated with very dilute ammonia, whereby only histidine is liberated, and lysine and arginine may then be recovered by treating the exchange material with an acid or a stronger base.  The amino acid solutions obtained as described may be treated again with exchange material or concentrated or purified in known manner.  Detailed examples are given.  The Specification as open to inspection under Sect. 91 mentions, as additional exchange materials, the sulphonated phenol-formaldehyde resins sold under the names "Duolite" and "Ionac"; the sulphonated aldehyde-phenol resins sold under the name "Dowex," and formaldehyde-tannic acid resins.  It refers also to the use of an aqueous solution of pyridine or aniline for recovering the absorbed polyamino acids, and includes an example of the use of pyridine. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the washing of pottery and other articles
IPC: A47L15/06
Filed: 1949-07-28
Abstract: 670,304. Washing crockery. DOULTON & CO., Ltd., HIND, S. R., MALKIN, E. W., MILLING- TON, G. R., and WATTS, A. W. Sept. 19, 1950 [July 28, 1949], No. 19819/49. Class 138 (i). Crockery is washed by moving the articles through a pre-determined path and spraying them with jets of water whilst they are rotated. The rotation may be caused by the reaction of the jets 'on the crockery, and/or by the action of the jets on impeller blades. The crcckery may be subjected to a preliminary wetting treatment, e.g. with further jets, before the wetting treatment. The invention is described with reference to a rotary table machine, but may be applied to a conveyor belt machine. It is applicable to individual treatment of cups, or to the treatment of plates stacked in a holder, but is designed primarily for use in a pottery works for washing off transfer labels during the course of manufacture. As shown in Figs. 1 and 2, a carrier 12, 13 is mounted freely on a vertical spindle 11 and is rotated manually by handles 47; an intermittent mechanical drive may be arranged if desired. At diametrically opposite positions on the carrier are freely mounted two vertical spindles 33, integral with impeller blades 31, on which crockery holders are mounted. The two spindles are separated by a pair of baffles 45. In Fig. 2 the right hand spindle is in the loading and unloading position and the left hand spindle is approaching the jets 40, which are universally jointed. Some jets spray upwards and some downwards to cover both sides of horizontally stacked plates, and all are tangential to the spindle to cause the spindle to rotate, such rotation being assisted by other jets impinging on the impeller blades 31. Water is circulated from the reservoir 70 by pump 71 and conduits 72 and back through drain troughs 73 and filter 74 to reservoir 70. The carrier is positively locked in either of two positions by a detent 50 actuated through shaft 53 by handle 54. Rotation of the spindles is arrested by a brake 60 actuated through lever 63 and rod 64 by handle 65. The washing operation may be viewed through a window 75 by the aid of a lamp 76. A plate carrier is shown in Fig. 3, and comprises a base 26 with conical recess and two driving lugs 27, which is placed over the conical portion 30 of spindle 33, the lugs 27 engaging corresponding recesses. Attached to the base 26 is a square base plate 22 having at three corners thereof vertical rods 23 with rubber studs 25 on which the plates rest horizontally. At the fourth corner is a pivoted rod 28 with rubber edge 28a secured in the operative position shown by a detent carried by a leaf spring 27. Fig. 5 shows a modified spindle 33 when cups are to be washed. The cup is mounted by a suction cup 81 and is freely rotatable. Jets play on the vanes 80 which rotates the cup and deflects water into its interior.
