Title: Production of viscose
IPC: D01F2/10
Filed: 1953-11-09
Abstract: The clarity of viscose, for use in the manufacture of filaments, films and other shaped articles, is improved, and the formation of undesirable deposits on the filters, jets and other parts of the shaping apparatus is thus prevented, by incorporating in the viscose, or in any raw material or intermediate product employed or formed in its manufacture, a sodium aldohexonate, i.e. the sodium salt of an acid of the formula HOCH2-(CHOH)4-COOH, namely gluconic, talonic, galactonic, idonic, gulonic, mannonic, altronic and allonic acids. Alternatively, there may be incorporated a compound which when added to aqueous caustic soda or to viscose forms a sodium aldohexonate without also forming a precipitate, examples of such compounds being the free aldohexonic acid or the potassium salt thereof or a lactone thereof, e.g. glucono-lactones.  The compound may be added to the caustic soda used for steeping the cellulose, to the alkali cellulose before or during shredding, to the undissolved or dissolved sodium cellulose xanthate or to the aqueous caustic soda employed in the latter dissolution.  The compound may also be added in stages.  A sulphonated fat, sulphonated fatty oil or sulphonated fatty acid may also be incorporated.  Examples are given.

Title: Improvements in and relating to flow meters
Inventor: FAVILL WILLIAM ARNOLD
IPC: G01F1/115
Filed: 1959-09-14
Abstract: 892,540. Electric selective-signalling systems. INTEGRAL Ltd. Nov. 10, 1960 [Sept. 14, 1959; Nov. 24, 1959], Nos. 31251/59 and 39890/59. Class 40 (1). [Also in Group XXXVI] A fluid flow meter of the type in which a rotor in a pipe induces pulses in an external coil, the pulses being counted to determine the quantity of fluid, is characterized in that means are provided in the pipe for distinguishing between the presence of air and liquid whereby the counter can be controlled so that it only counts pulses caused by the flow of liquid as opposed to those caused by the flow of air. In the two embodiments described the liquid/air distinguishing means comprise two probes the electrical resistance between which is high when air is present but relatively low when a liquid, such as milk, is present. The circuit controlled by the probes, a Wien bridge oscillator, is so arranged that when liquid is present only a low potential exists between the probes which tends to minimize electrolytic corrosion. In the first embodiment, Fig. 2, of Provisional drawings 31251/59 a stainless steel rotor 13, mounted on two spiders 24 has, embedded in it, a magnet which induces pulses in a coil 9. The two liquid/air detecting probes are constituted by a bolt 10, supporting the coil 9, and the wall 8 of the pipe. In the second embodiment, (Fig. 2, of Provisional drawings 39890/59, not shown), the liquid/air detecting probes are not combined with the pick-up coil but are mounted away down stream from it. As in the first embodiment, one probe is constituted by the pipe wall. In both embodiments the electrical circuit is as in Fig. 1 of Provisional drawings 31251/59. The detecting probes, when air is present cause a Wien bridge oscillator, (Fig. 4, of Provisional drawings 31251/59, not shown), to oscillate. These oscillations are rectified to energize a relay which closes a gate thereby isolating the counter, which can be as described in Specification 752,496, which is referred to, from the pick-up coil. When liquid is present in the pipe the gate is not closed and pulses induced in the pick-up coil are passed to the counter.

Title: Improvements in and relating to coin freed telephone installations
IPC: H04M17/02
Filed: 1936-11-16
Abstract: 490,660. Automatic exchange systems. MERK TELEFONBAU AKT.-GES., F. Nov. 16, 1936, No. 31355. Convention date, Nov. 14, 1935. [Class 40 (iv)] [Also in Group XVIII] . In prepayment telephone apparatus, the desired connection is completed only when coins equal in value to the maximum charge payable for a call have been inserted, certain of these coins equal in value to the charge for the call being " cashedin " by metering impulses from the exchange, and the remainder being " cashed-out." As shown, the inserted coins pass down a shoot K and oscillate a lever B which through ratchet and pawl mechanism R, steps forward a contact arm a to close the circuit to line of the substation apparatus A after a certain number of coins have been inserted. A relay W responsive to alternating current and a relay N responsive to direct current are provided at the substation, operation of relay W alone causing collection of a coin, whilst subsequent operation of both together causes return of the remaining coins. At the conclusion of the call, a winding I of a relay Z at the exchange receives the appropriate number of impulses from the metering device the relay repeatedly changing over contacts z<2> and z<3> so that the relay W receives alternating current impulses from a transformer S, causing a number of coins to be collected in succession depending on the number of metering impulses. When the connection at the exchange is broken, a relay T is de-energized and changes over contact t<1> which de-energizes a delayed release relay H. A second winding II of relay Z is thus energized for a short period by way of contact t<1> and contact h of relay H. This causes energization of relay W, and simultaneously energization of relay N, through contact w of relay W and contact t<2> of relay T, to return the surplus coins. The impulses may be transmitted to relay W to collect the fee chargeable, during the course of the call instead of at the end. The Specification as open to inspection under Sect. 91 refers also (1) to a modification in which surplus coins are cashed-out after the delayed return of the receiver hook, relay N, relay H, and winding II of relay Z being then dispensed with, and (2) to a modification for receiving coins of different values in which coins of higher value are cashed-in before those of lower value. This subject-matter does not appear in the Specification as accepted.
