Patent GB-749718-A (GB)
Title: Production of 2-methyl-5-ethylpyridine
Filed: 1953-10-20
Abstract: 2 - Methyl - 5 - ethyl - pyridine is obtained by reacting paraldehyde and ammonia at elevated temperature and pressure, there being added to the reactants a product of the reaction which can be distilled only above the temperature at which 2-methyl-5-ethylpyridine boils under the same pressure.  The paraldehyde may be used in the form of the equilibrium mixture obtained by treating acetaldehyde with an acid such as sulphuric acid, e.g. by maintaining acetaldehyde containing 0.1 per cent by weight of sulphuric acid at 20 DEG  C. for an hour.  Preferably excess ammonia is used and the process is carried out in the presence of an ammonium salt as catalyst. Suitable catalysts are the acetate, chloride, carbonate or sulphate. The reaction is carried out at temperatures in the range 200 DEG  to 250 DEG  C. in an autoclave capable of withstanding pressures of 500-1000 p.s.i.g.  A reactor of stainless steel, preferably chromium-nickel steel, gives improved yields.  The process may be carried out batchwise or continuously. When it is carried out continuously it is advisable to have an emulsifying agent, e.g. sorbitan monolaurate or a polyoxyalkylene ether of sorbitan monolaurate, present.  The aqueous phase of the product may be extracted, e.g. with chloroform, benzene or ether, and combined with the non-aqueous phase prior to distilling to recover the methylethyl pyridine, and high boilers for re-use. The aqueous phase may in part be recycled with addition of ammonium salt or acid to maintain the catalyst concentration or after removal of water.

Title: Gripper type linear motion device
IPC: H02K7/065
Filed: 1970-06-15
Abstract: 1275517 Ratchet mechanism COMBUSTION ENG Inc 15 June 1970 [18 June 1969] 28932/70 Heading F2Q [Also in Divisions G6 and H1] In a magnetic linear motion stepping device a shaft 12 bears plural spaced axial projections and moves axially of a tubular magnetic pressure housing 14 surrounded by 5 spaced coils A to E. Within the housing fixed sleeve 15 surrounds the shaft and comprises radial lower, central, and upper stops 17, 18, 19, contacting the inside of the housing. A lower magnetic slug 22 including upper and lower stops 23, 24 surrounds the sleeve and is spring buffered at each end to permit free motion within the sleeve stops, and a similar upper magnetic slug 32, has upper and lower stops 33, 34. Radial non- magnetic inserts 27 in the housing within the several coil windings direct flux through the shaft and the slugs, so that energization of coil E or C lowers or raises slug 22, and energization of coil A or C raises or lowers slug 32. Energization of coil D raises magnetic latching slug 43 against spring 45, to engage latch 42 with the projections while energization of coil B raises magnetic latching slug 53 against spring 54 to engage latch 52 with projections. Sequential energization of selected coils raises or lowers shaft 12. In operation, coil D is energized to operate latch 42 and coil B is de-energized to release latch 52. Coils A, E are de-energized to release the upper and lower slugs 22, 32 and coil C is energized to lower slug 32, and raise slug 22 together with the shaft latched thereto. Coil B is energized to engage latch 52, and coil D is de-energized to release latch 42. Coil C is de-energized to release upper and lower slugs 32, 22 and coil E is energized to lower slug 22. Energization of coil A raises slug 32 together with the shaft latched thereto. Further lifting steps are effected by repeating the cycle. Energization of coils A, B, E holds the shaft with slug 32 against stop 19 while slug 22 is held against stop 15. De-energization of coils A, E releases slugs 32, 22 which are held against stop 18 by energization of coil C, and the shaft is lowered one step.  Energization of coil D engages latch 42 with the shaft, and energization of coil B releases latch 52. Energization of coils A, E and deenergization of coil C disengages slugs 22, 32 from the central stop and engages them with stops 17, 19 to lower the shaft a further step. Energization of coil B and de-energization of coil D engages latch 52 and disengages latch 42 to complete the cycle, which may be repeated.

Abstract: 433,247. Soldering or welding dentures. RAKOS, A., 1, Eszterhazygasse, Vienna. Oct. 15, 1934, No. 29438. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 14, 1935.] [Classes 83 (ii) and 83 (iv)] [See also Group VI] Metal dentures permanently fixed in the mouth are electrically soldered or welded by fixing one electrode to the denture and intermittently applying to the place of treatment a carbon electrode connected to the other terminal of the circuit. The heat is generated by the resistance of the carbon. One electrode consists of a clamp 5 and the other of a carbon rod 1, preferably of compressed retort carbon and of diameter up to 10 m.ms. The rod is secured by an adjustable clamp 2 to a handle 3. The electrodes are connected by flexible cables to the secondary 7 of a transformer, the primary and secondary coils being preferably arranged on separate branches thereof. The tension between the electrodes varies from 4-6 volts at intensities between 10 and 100 amperes. When soldering solder and fluxes are fed to the carbon, the work is cooled by squirting water thereon. The Specification as open to inspection under Sect. 91 states that the process may be applied to soldering or welding metal tarsia in a wood base. This subject-matter does not appear in the Specification as accepted.

Filed: 1936-10-29
Abstract: 470,891. Substation equipment. TELEPHON-APPARAT-FABRIK E. ZWIETUSCH & CO. GES. Oct. 29, 1936, No. 29450. Convention date, March] 14. [Class 40 (iv)] [Also in Group XVIII] In a telephone paystation, the tendered coin is held in suspense during the call, and is refunded at the expiration of a delay period following replacement of the receiver unless, during that period, a magnet, energized by replacement of the receiver, is de-energized by the operation of metering equipment in the case of a chargeable call. As shown, a coin passed down a shoot 1 is held by a stop 3 on a lever 5 pivoted at 4, and operates contacts m<1>, m<2> respectively removing a short-circuit over dial contacts nsi, and preparing the circuit of the refund magnet KM, which latter is, however, at first broken at contacts v. When the receiver is removed, a pin 13 on the hook HU engages over a shoulder 16 on a bar 15 supported by a fixed pin 20 working in a slot 19, and actuated by tension springs 17, 18. Upon replacing the receiver, the pin 13 depresses the bar 15, which, after a fixed pin 23 has passed over a guide 24, is turned clockwise by the spring 18 to disengage the pin 13, so that it now commences to return upwardly under the action of the spring 17 and control of a pump 22. During this upward movement, the pin 23 bears against a second guide 26 on the bar 1 and a pin 25 on the bar engages a lower cam part 9 on the lever 5 to withdraw the stop 3 and insert a lower stop 6 to which the corn falls. In this position, the coin is also supported by further stops 10 and 11 operated by the magnet KM, which is now energized through holding contacts k, m in parallel with the coin contacts m<2>, and the contacts v. If the call is successful, contacts x, operated by the metering mechanism at the exchange, are at this stage opened, so that the magnet KM is de-energized and the stop 10 withdrawn to release the coin into the casbing-in shoot 8. If the call is unsuccessful, the contacts x remain closed and the magnet KM remains energized, so that, when the bar 15 approaches its uppermost position and engages an upper cam part 9 on the lever 5 to withdraw the stop 6, the coin is released into the cashing-out shoot 7, the contacts v opening immediately after as the bar 15 reaches its uppermost position.
