Patent GB-830795-A (GB)
Title: Improvements relating to recovery of tetracycline
Filed: 1957-03-04
Abstract: Tetracycline is recovered from the mother liquor solution obtained in the reductive dechlorination of chlortetracycline by diluting said solution with water, adjusting the pH of said solution to between 2.5 and 3.3, adding an alkaline earth metal compound thereto so as to raise the pH to 4.0 to 4.5 and recovering the resulting precipitated alkaline earth metal salt of tetracycline.  An aqueous alkali such as sodium hydroxide, sodium carbonate or ammonia may be used for the initial adjustment of pH.  The examples describe the preparation of calcium tetracycline using calcium hydroxide for providing the calcium ions.  Barium hydroxide may be used in place of the calcium hydroxide.  The alkaline earth metal salt of tetracycline may be converted into a mineral acid salt of tetracycline such as the hydrochloride by slurrying with an alkoxy alkanol, e.g. 2-methoxyethanol or 2-ethoxyethanol, or an alkanol, e.g. methanol, ethanol and nbutanol, adding a nitrogenous base such as ammonia, triethylamine, ethanolamine or morpholine, separating insolubles and adding a mineral acid such as hydrochloric or sulphuric acid. Reference has been directed by the Comptroller to Specification 747,779.

Filed: 1949-03-15
Abstract: 659,916. Teleprinters. BLOCK & ANDERSON, Ltd., and ANDERSON, A. March 15, 1949, No. 7093. [Class 100 (iv)] In a teleprinter utilizing a sprocket-fed web of forms, a hectographic carbon paper arranged between the form on which the message is typed and the platen, with the transfer face adjacent the form, is fed independently of the web of forms but, like the latter, under the control of a key on the teleprinted keyboard. The unit for supporting the teleprinter platen carriage is releasably mounted on the machine by means of a tubular socket 1, Fig. 1, fitting over a vertical spigot on the machine, and a spring latch 2 engaging an abutment on the machine, a stopsurface 3 on the unit bearing against an equivalent surface on the machine. The carriage comprises a platen roller 4 slidable on a splined shaft 5 on the supporting unit and carrying a ratchet-wheel 6 rotated step-by-step by a pawl to effect line-spacing. The roller 4 has at each end sprocket-teeth 7 engaging perforations 9 in the web of forms 8 to feed the latter. Fingers 10 maintain the web in engagement with the teeth, and the web is held only lightly and not pressed against the roller. A spring causes the carriage to return to the right when released by the carriage return key. Ink-ribbon mechanism.-Supply and take-up rolls 23, 24 of carbon paper, wound with the transfer face inwards, are mounted in spool holders 22, 21 mounted in end-plates 12, 13 spaced by rods 14, 15, Fig. 5, and by a curved plate 16, which also acts as a guide for the free end of the web of forms. This assembly constitutes a framework attached to the rear of the carriage to move laterally therewith, and is separately supported by screws 18 and a roller 17 running on a rail 19 on the supporting unit and maintained in engagement with the rail by a stirrup 20 attached to the screws 18. A curved bar 26 carried by arms 28 journalled in the plates 12, 13 acts to tension the carbon paper between the supply roll and the platen, the arms 28 being spring-loaded downwards. On actuation of the carriage return key, a bar 46 carried on parallel links 47 secured to the supporting unit is raised and raises a plate 34 slidably mounted on the plate 12 and urged downwards by a spring 38. The raising of the plate 34 by means of a stud 45 raises the bar 26 to release the tension in the carbon paper, releases retaining pawls 40, 33 from ratchet-wheels 39, 32 on the spindles of the rolls 24, 23, and rotates the take-up roll 24 one step by means of pawl 43, to feed the carbon paper, over-running being prevented by spring-loaded friction brake levers engaging one end of each spool holder. On return of the plate 34, the bar 26 draws paper off the roll 23. A mirror-script copy of the message is obtained on the back of the form.

Title: Improved change-speed mechanism for the turntable of a disc talking machine
Inventor: GUEST LAWRENCE VINCENT
IPC: F16H15/46
Filed: 1958-03-05
Abstract: 852,657. Turntable driving means. BIRMINGHAM SOUND REPRODUCERS Ltd. Feb. 25, 1959 [March 8, 1958], No. 7150/58. Class 40 (2). [Also in Group XXIV] In a change-speed gear for a disc talking machine wherein a multi-stepped wheel 6 on a motor spindle 5 frictionally drives a turntable rim 2 through a rubber - rimmed idler 11 axially shiftable under manual control, the said idler shift is by a cam bar 20 from smaller to larger steps of the wheel 6 and by a return spring 14 from larger to smaller steps, and a motor switch lever 29 simultaneously switches off the motor and transversely disengages the idler from the stepped wheel 6 and, whilst the motor is switched off, retains the idler in its disengaged position but without restraint against axial shift in either direction. The idler 11 is mounted on an arm 16 pivoted by its spindle 15 on a yoke 13 sliding and pivoting on a fixed spindle 12. The free end 26 of a spring 24 which is upwardly biased to hold the cam bar 20 against the motor board engages the top of the yoke 13 and is flanged at 27 to coact with the steps of the cam bar 20 so that rightward cam movement by a hand-control 21 depresses the yoke 13 through the spring end 26 against the return spring 14 which is anchored on the fixed spindle 12 and on the yoke 13, thereby also acting torsionally to engage the idler 11 with the stepped wheel 6 and the turntable rim 2. The lever 29 is moved to close a motor switch 28 against a spring 31 by a hand lever 32 through a rod 33 and a latch lever 34 and has an abutment 39 which, when the switch 28 is open, engages an abutment 17 on the arm 16 to disengage the idler 11 against the spring 14 and to guide the arm 16 for axial shift of the disengaged idler. Alternatively, the latch lever 34 may be actuated automatically on completion of the playing of all the records on an automatic machine by means described in Specification 839,666. The disengagement of the idler prevents deformation of its rubber rim during long rest periods. The idler may be axially shifted in either direction when the motor is switched on, the resilience of the idler rim accommodating the shifts from smaller to larger steps of the wheel 6; further, the risers of the said steps may be tapered to facilitate shift. The spindle 15 is threaded at 40 and has a screw-driver slot 42 for axial adjustment with respect to the yoke 13, the arm 16 being circumferentially retained with respect to the spindle 15 by frictional means comprising a spring washer 41 engaged in a circumferential slot in the spindle 15. The thread 40 permits the arm 16 to pivot freely without materially effecting the vertical adjustment.
