Title: Hydrogenated formyl pterins
IPC: C07D475/04
Filed: 1951-03-22
Abstract: The invention comprises 5, 6, 7, 8-tetrahydro-5-formylpteroyl glutamic acid and the alkali metal salts thereof, and a process for producing the above compounds by heating an aqueous solution of an alkali metal salt of the corresponding 5,6,7,8-tetrahydro-10-formyl pterin containing caustic alkali and, when the free amino acid amide is required, acidifying with acid.  After the heating, the pH of the solution may be brought back to substantially neutral and treated with an absorptive material such as activated silicate-particularly magnesium silicate.  After the silicate has been separated from the solution, acid is added to lower the pH to about 4 to form the free amino acid amide which may be absorbed on to charcoal.  The charcoal may then be treated with aqueous ammoniacal alcohol to remove the free amino acid amide and the resulting solution is heated to dryness.  In the examples the free amino acid amide and the sodium salt thereof are prepared.

Filed: 1923-11-19
Abstract: 225,367. Barnard, D. J. Nov. 19, 1923. Grab.buckets.-Relates to sinle-chain grabs of the type supported by a button on the chain whilst the trip mechanism is lifted from the discharging ring and the grab lowered to the ground. A thimble 11 with inner sliding member 13 is mounted between the upper block plates 7 in the grab-head, and a pair of weighted pawls 17 are pivoted on the block plates and project through slots in the plates, thimble and inner member to co-operate with the button 30 on the lifting chain. The grab is suspended from the discharging ring 27 by hooks 20 arranged at right angles to the pawls 15 and provided with pins 21 which move in slots 22 in lugs 23 in the thimble 11. Arms 24 on the lower ends of the hooks 20 project through slots in the, thimble and engage the inner sliding member 13. With the grab suspended on the ring 27, as shown in Fig. 4, the member 13 is held up by the arms 24 of the hooks 20 and the pawls 17 are raised by their weighted ends 15. When the chain is hauled in the button 30 engages the pawls 17, the open grab is lifted from the ring 27 and the hooks 20 fall outwards as far as is permitted by stops such as 31, the pins 21 falling to the bottom of the slots 22. The open grab can then be lowered past the ring, and when it rests upon the ground the button 30 is disengaged from the pawls 17, which are then lowered by the weight of the sliding member 13. On hauling in the chain, the button passes between the pawls 17 and the grab is closed, the weight of the member 13 bringing the hooks 20 into position to engage the discharging ring. A guide 12 secured between the lower parts of the block plates limits the downward movement of the button 30. A guide 28 on the upper part of the block plates brings the discharging ring into position to engage with the hooks.

Title: Improvements in or relating to apparatus for measuring time intervals
IPC: G04F8/00
Filed: 1946-09-30
Abstract: 617,004. Reaction-time measurement apparatus. HARVEY, H. C. Sept. 30, 1946. No. 29172. [Class 81 (ii)] [Also in Group XVIII] An apparatus for measuring periods of time comprises a rotating hand or like indicator, a continuously running motor, non-positive coupling means connecting the motor to the indicator, primary arresting means for holding the indicator at a predetermined starting position while the coupling means slips, a releasing device for rendering the primary arresting means ineffective, and secondary arresting means arranged to stop the indicator at the end of the period to be measured. A shaft 21, Fig. 3, continuously driven by a synchronous motor carries, at its front end, a hand, not shown, which moves over a graduated dial. A finely toothed wheel 22 is frictionally mounted on the shaft 21 and can rotate therewith, the sleeve of said wheel 22 carrying a second hand also moving over the graduated dial. A tooth 33 on an armature 34 normally urged upwardly by a spring 39 engages a projection 32 on the wheel 22 which is thereby held in its starting position. Upon energisation of a magnet 35 the armature 34 is moved downwardly so releasing the wheel 22 to rotate the second hand over the dial. Upon energisation of an electromagnet 46 a vertically disposed armature 42 is moved to the left and a spring pawl 41 carried thereby engages the teeth of the wheel 22 which is again arrested. The second hand will thus indicate the period of time between the energisations of the electromagnets 35, 36 respectively. The armature 42 is maintained in its arresting by a shoulder 48 on a pivoted lever 38 until by another energisation of the electromagnet 35 the lever 38 is pulled down by a link 50 attached to the armature 34. When the device is used to test the "reaction lag " of a workman it is arranged so that when the electromagnet 35 is energised to free the wheel 22 a lamp 81 is lit whereupon the workman pulls on a lever 79 to close a switch 78 and energise the electromagnet 46 to arrest the wheel 22. The hand carried by the wheel 22 will thus indicate the time taken by the workman to "react" to the lighting of the lamp 81. The speed of rotation of the shaft 21 can be checked against a stop watch 71 which may be started when the electromagnet 35 is energised and stopped when the contacts 51, 52 are closed by a projection 56 carried by a disc frictionally mounted on the shaft 21 and freed to rotate therewith when the armature 34 is attracted by the electromagnet 35.
