Title: Process for the production of paraffin-hydrocarbons with more than one carbon atom
IPC: C07C1/02
Filed: 1926-03-26
Abstract: 255,818. Fischer, F., and Tropsch, H. July 21, 1925, [Convention date]. Methane homologues.-By conducting the reaction between oxides of carbon and hydrogen at a temperature lower than that required for the formation of mainly methane with the particular catalyst required, the homologues of methane such as ethane and propane are obtained when using substantially ordinary pressure. Thus, when using a catalyst consisting of a mixture of zinc oxide and finely-divided iron, methane only is obtained at 430‹ C.; at 380‹ C., however, the products comprise 80 per cent methane and 20 per cent homologues; while at 300‹ C., only 10 per cent methane results, together with 90 per cent of other paraffin hydrocarbons. The use of pure nickel as catalyst is excluded. Specification 2306/14 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of a few atmospheres pressure. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to prepayment mechanisms
IPC: G07F15/06
Filed: 1936-03-21
Abstract: 472,597. Prepayment mechanism for basic or fixed charges. UNITED GAS INDUSTRIES, Ltd., and ANGOLD, H. E. March 21, 1936, No: 8547. [Class 27] A prepayment mechanism for charging a fixed charge, such as rent, by a constant speed driving element operating a quantity mechanism or setting mechanism, which takes account of the fixed charge, the mechanism permitting the supply of commodity by meter while arrears of fixed charge are being paid, comprises a spring which is tensioned proportionately to the arrears of fixed charge and is permitted to unwind gradually so as to add to the drive of the setting or quantity mechanism for current fixed charge a proportional drive representing arrears. A constant speed motor 1 drives through reduction gearing and gearing involving one or more worm and worm wheel transmissions, a constant speed spindle b having a pinion b<1> meshing with a pinion cl rigid with one sun-wheel c of an epicyclic gear, the second sun-wheel d of which serves to transmit the drive to the quantity or setting mechanism through a wheeldl: As long as the basic charge is prepaid, the wheels d, d<1> can rotate and the planet carrier e, having pinions meshing with the wheels c, d, remains stationary. When the prepayment is exhausted, the sunwheel d is arrested and the drive from the motor causes the carrier e to rotate bodily and rotate a shaft e<1> geared to a spindle g which is thereby rotated from a zero position with an arm g<5> against a fixed stop g<4> to wind up a spring g<2>. A pointer g<3> on the spindle g is moved over a dial to indicate the extent of arrears of fixed charge. When the wheel d is again freed by prepayment of accruing fixed charges, the wheel c is driven as before and the shaft el and carrier e are also rotated in the reverse direction by the relaxing spring to add to the drive. In order that the rotation of the carrier e by the spring g2 may not be at too high a speed, the shaft e<1> is geared to one member h of a one-way clutch device, the other member h<1> of which is driven from the constant speed motor through the spindle b and gears b<2>, h<2>. The member h<1> is slidable on its shaft and pressed towards the member h by a spring, so that it can overrun the member h, when no arrears are to be charged. The members h, h<1> may be disengaged when required by a fork i on a sliding spindle il operated from outside the apparatus. In a modification, for controlling the unwinding of the spring g<2>, a ratchet-and-pawl device is provided on the spindle b, the ratchet wheel being rigid with a wheel driven by the spring. In a further modification, an escapement device is provided between the spindles b, e<1> to allow the spring g<2> to relax in stages. Mechanism for adjusting the value and range of the fixed charge may be provided as described in Specification 472,598.

Title: An improved method of making superior quality artificial silk in high yield by the wet spinning process
IPC: D01D7/00
Filed: 1932-03-24
Abstract: For the collection of viscose, cuprammonium, cellulose acetate, and other wet spun silks, there are used permeable or perforated bobbins or rollers of more than 200 mm. diameter, for example, of 300 or 400 mm. or more diameter, and on these bobbins are wound one or more laps of at least 300 grms., preferably of 500 grms., dry weight, although laps of 1000-2000 grms. may be applied.  By providing for the collection of such extended lengths on a single roller, wastage is minimized, the time of spinning is prolonged, and higher spinning speeds up to 100 metres per minute or more are permitted, particularly if the bobbins are driven by roller friction.  The threads are washed in the bobbins &c. by the pressure or suction method, and, if desired, they are also desulphurized, acidified, decoppered, bleached, oiled and then dried on the bobbins.  The threads are removed into skeins of the usual length, which are sorted into qualities.

Abstract: 1433282 Tape recorder control circuits UHER WERKE MUNCHEN 27 Feb 1974 [11 Sept 1973] 8895/74 Heading G5R When the tape in a tape recorder, e.g. of the cassette type, is running a control transistor T1 is maintained conducting whereby a Darling- ton pair of transistors T2, T3 are maintained non-conducting and a device 1 is thereby not energized, and when the tape stops T1 turns off and T2, T3 turn on to energize device 1 for thereby effecting release of all the operation selection push button switches of the recorder from their operative positions. The device 1 is a circuit-breaking relay which also acts to release or cause release of the push button switches. When the tape is running a contact K1 is closed once per revolution of a drive wheel of a tape position indicating counter, thereby charging capacitor C2 to maintain a potential thereon sufficient to keep T1 conducting and relay 1 de-energized, the charging of capacitor C2 ceasing when the tape and thus the counter drive wheel stops so that T1 turns off and relay 1 is energized. The circuit reverts to its standby position-T1 on, T2 and T3 offin a few milliseconds after T2, T3 turn on to allow rapid change of operating mode. A capacitor C1 ensures that T1 turns on immediately after selection of a tape running mode. T1 is also maintained on when a pause push button is operated because a contact A is then closed to apply a positive potential to capacitor C2. When the tape counter reaches zero, or a position pre-set by a memory control, a contact K2 closes to turn T3 on whereby relay 1 returns the apparatus to the stop condition.
