Abstract: 1394786 Phosphorus oxybromide HOECHST AG 19 June 1973 [21 June 1972 19 Feb 1973] 29007/73 Heading C1A Phosphorus oxybromide is prepared by reacting phosphorus tribromide with oxygen in the presence of nitrogen oxides in an organic solvent at a temperature of from 0 to 120 C. and separating the phosphorus oxybromide by crystallization or vacuum distillation. Preferably distillation is carried out at sump temperatures of from 60 to 160 C. under a pressure of from 10 to 300 mm. Hg after the solvent has been distilled off. The term "nitrogen oxides" includes NO 2  and its dimer, NO and dinitrogen trioxide, N 2 O 3 . Specified solvents are halogenated hydrocarbons, especially fluorinated and chlorinated hydrocarbons having boiling points below 150 C., used in amounts of from 20 to 90 volume per cent of PBr 3 . When carrying out the process continuously, the solvent is removed as far as possible by distillation after reaction at sump temperatures above 50 C. The oxidation is preferably carried out at normal pressure, although pressures from 0À5 to 10 atmospheres may be used. Traces of phosphorus pentabromide in the reaction product may be removed by distillation, the PBr 5  splitting into Br 2 , which distils off, and PBr 3  which may be filtered from the POBr 3 .

Patent GB-309386-A (GB)
Title: Improved electric winding-up mechanism for clockworks
IPC: G04C1/06
Filed: 1927-11-07
Abstract: 309,386. Krausse, B. Nov. 7, 1927. Winding - apparatus, electric.-In clockwork mechanisms wherein the mainspring is maintained wound-up within certain limits by electrical means, the winding train between the motor and the mainspring includes a multistep clutch, which co-acts with the spring barrel to control the motor circuit contacts. The motor is of the Ferraris or shading-coil type. An operating member 1, loose on the winding shaft 2, has a pin 6 driven by a pin 5 on the spring barrel 3 so that the member 1 rotates clockwise, Fig. 1, and pins 7 - - 12 on it meet in succession the longer contact 14 of two normally closed contacts 13, 14 in the circuit of the electric motor 34, which latter drives the winding wheel 4 rigid on arbor 2. The member 1 may also be driven clockwise by a pin 15 on it co-acting with tappets 16 - - 21 on discs loosely mounted on the arbor 2, the last tappet 21 being driven by a pin 22 rigid on arbor 2. If the current be switched on the motor 34 drives wheel 4 and shaft 2 and winds up the mainspring; at the same time the pin 22 rotates the loose discs so that they each rotate 360‹ less the thickness of the tappet 19 (or 17, or 15) until the tappet 16 turns the pin 15 and member 1 until the next one of pins 7 - - 12, say 12, meets the blade 14 and forces it away from the blade 13 thus stopping the motor. In this action the pin 6 has moved away from the pin 5. When the spring has run down a little the pin 5 moves clockwise, Fig. 1, and in a little while meets the pin 6, carrying the member 1 along with it so that the pin 12 wipes past the blade 14. The latter resumes its normal contact with blade 13 and energizes the motor, rewinding the mainspring until the next pin 7 moves the blade 14 away from blade 13. In modifications, the operating member 1 is replaced by a starshaped member or by a one- or two-armed lever. In modifications for limiting the relative rotation between the member 1 and the wheel 4, (1) gearing is used in which the last wheel has the gap between two teeth filled up and (2) a chain is wrapped round the arbor 2.

Title: Paper feeding apparatus for printing and like apparatus
IPC: B41J15/24
Filed: 1961-08-17
Abstract: 965,279. Selective printing. CLARY CORPORATION. Aug. 17, 1961 [Aug. 29, 1960], No. 29719/61. Heading B6F. Relates to apparatus including intermittently rotated members 16, 19, Fig. 1, for drawing superposed flexible record strips 11, 12 from a supply bin 20 past a printing head 13, the strips being discharged to separate bins 18, 21. A spring 9, bearing on the strips and located between head 13 and feeding members 16, 19, imposes a drag on the strips. The strips have lateral feed perforations and may have lateral embossed parts to help them to adhere together. Feed of inner strip 12, Fig. 2.-Strip 12 is threaded between a guide 58 and a friction surface 26 on roller 16, driven intermittently by a solenoid, and then engaged by sprocket teeth 50 carried by roller 19 driven from roller 16 by belt 52, teeth 50 engaging the lateral perforations in the record strip. The initial movement of teeth 50 tightens the strip on to surface 26 which then also feeds the strip. The effective diameter of surface 26 is slightly larger than that of teeth 50 so that the former advances the strip a little faster than teeth 50 do and thus strain is removed from the strip perforations. Feed of outer strip 11, (Figs. 2 and 7).-Surface 26 is flanked by freely rotatable sprockets 10, the teeth 17 of which engage in the strip perforations so that the movement of strip 12 positively drives these sprockets. Since teeth 17 also engage the perforations in strip 11, that strip is also advanced and is then led between plates 58 and 61 to bin 18. Sprockets 10 are eccentrically mounted on the shaft of roller 16 so that teeth 17 stand proud of surface 26 over the desired arc only. Threading.-To thread strip 11, plate 61 can be swung down about pivot 65 against spring 66 and is latched to thread strip 12, longitudinally slidable lock rods 76, 77 are withdrawn to allow bottom plate 74 to be swung down about pivot 75. Line-spacing.-Manual feed is effected by depressing a lever (not shown) which rotates plate 84, Fig. 7, and hub 85 about shaft 23 of  roller 16. A second hub 87 is aligned with hub 85 and is keyed to shaft 23. A one-way clutch effect is provided between hubs 85, 87 by a helical spring 89 surrounding both and secured to the former. Plate 84, when released is restored by a spring. Repeated depression of the lever gives intermittent feed.
