Title: Improved treatment of peat and the like
IPC: C10F5/00
Filed: 1921-03-12
Abstract: 183,180. Thermal Industrial &. Chemical (T.I.C.). Research Co., Ltd., and Morgan, J. S. March 12, 1921. Plant.-Sewage sludge or the like, is heated in an autoclave to a temperature at which colloidal matter coagulates and is filtered without any substantial fall in temperature. Steam is generated from the filtered sludge and is used in the autoclave for heating the unfiltered sludge and expelling liquid therefrom when it is on the filter. The sludge is fed with or without added water into a pulping machine b from which a pump c forces it through heat exchangers d, e. The pulp at a temperature between 50‹ C. and 100‹ C. passes into an autoclave f and is exposed by an agitator g to the steam at about 150‹ C. evolved from peat in a vessel p containing molten metal. The pulp flows over a weir and is forced on to a rotary drum filter h by the difference in pressure caused by action of an exhauster i which draws the hot water and steam into a separating vessel l whence they pass to exchangers d and e respectively. The partially dried sludge is removed by the scraper n and enters the closed vessel p containing molten metal and having a valve loaded to ensure a temperature of about 160‹ C. The sludge is forced into a bunker s and delivered to a briquetting machine u. A lower moisture content than 15 per cent may be secured by using the waste heat from the flue gases of the furnace which heats the metal bath. Specification 174,974, [Class 64 (i), Heating liquids &c.], is referred to.

Title: Locking device to prevent undesired or unauthorised movement of a motor car from rest
IPC: B60R25/00
Filed: 1938-03-16
Abstract: 498,958. Locking vehicle wheels. TALENT, V. March 16, 1938, No. 8077. Convention date, March 31, 1937. [Class 103 (i)] [Also in Groups XXXI and XXXV] To lock a motor vehicle against unauthorized or inadvertent starting, a normally spring - retracted slidable detent 4 is moved into engagement with a cogged disc 1 or the like on the propeller shaft C, being held in both operative and inoperative positions bya transverse spring- pressed bolt 12 releasable only by depressing the clutch pedal P, whilst the actuating means 19 for shifting the detent 4 after such release, is interrelated with the ignition switch so that the ignition key 10 cannot be turned or removed until the detent has been set to lock the propeller shaft and, vice versa, the detent cannot be withdrawn while the ignition switch is open. The detent slides in a guide casing 3 on the gearbox E, a pin 8 thereon projecting through a slot 3f in the casing. Thrust is imparted to the detent by means of a rod 7 sliding in supports 5, 6 on the base plate 2 and casing 3 respectively, a compression spring 10 normally retracting the rod 7 and a spring 11 connecting the pin 8 to the support 6 to hold it in contact with the end of the rod. The bolt 12, engageable with recesses 4a in the side of the detent, is connected by a Bowden cable 13 to the clutch pedal P. The rod 7 is operated through a lever 15 and linkage 16 when a slidable rod 19 carried on the steering pillar A is pulled upwards the upper end of the rod 19 passing through the ignition switch box 17 and terminating in a handle 19b. Within the switch box, a lever 20 with a projecting handle is pressed by a spring 21 against the rod 19 and, when the rod is raised engages an annular groove 19a therein to hold the locking means in engagement. The ignition switch, located under the, lever 20, comprises a spindle 22 extending from a rotary barrel lock 18a and carrying an arm 23 adapted to engage terminals 24. On the spindle is also a collar 25 with a flattened portion which, when the lever 20 is out of engagement with the groove 19a, bears against its underside, preventing opening of the switch. When the lever is in engagement with the groove and the switch is opened, the collar 25 comes behind the lever, preventing retraction thereof to release the operating rod 19 until the switch is again closed. When, after closing the switch, the lever 20 is pulled back, it is withdrawn past its normal position until it engages an abutment 17a on the casing, whereby a lug 20b on its underside momentarily closes contacts 26 in the circuit of the engine starting motor. The lever 20 may be held out of action, as when using the device for turning on a hill, by means of a rotatable spring pressed plunger 27, normally held out of engagement by a cam head 28 riding on an inclined abutment 32.

Title: Improvements in and relating to a luminophore comprising a composite phosphate activated by cerium
IPC: C09K11/77
Filed: 1949-03-25
Abstract: 701,031. Luminescent materials. GUNTHER, G. G. J., ANDERSON, G. G. B., and LUMALAMPEN AKTIEBOLAG. March 25, 1949, No. 8211/49. Class 39(1) Luminescent material comprises a sintered material containing a composite orthophosphate of aluminium and at least one metal of the second group of the periodic system having an atomic weight less than 200, activated by cerium in trivalent form. The molar ratio of Al 2 O 3  : MeO in the material lies within the limits 3: 1 and 1:3, preferably 1:1. The cerium is contained in the material to the amount of 0.1-20 per cent, measured as Ce 2 O3. The sintering process can either be effected in one stage in damp hydrogen, or heating may be effective first in air to 1000-1250‹C (which partially oxidizes the cerium to tetravalent form), and thereafter in a hydrogen atmosphere for reduction of the cerium to trivalent form. Increased intensity of the material and displacements of the emission spectrum are obtained by minor admixtures of metals acting either as secondary activating agents or to increase absorption, e.g. at least one of the metals Pb, La, Zr, Bi, U, Tl and V. Methods of preparing composite phosphates of Al with Mg, Zn, Ca, Ca, and Ba, Sr and Zn, Ca and Ba and Mg, Sr and Mg, and Be are described. Specifications 512,154 and 645,335 are referred to.

Title: Improvements in frequency multipliers for alternating electric currents
IPC: H03B19/10
Filed: 1921-03-16
Abstract: 160,179. Trichard, P. March 16, 1920, [Convention date]. Frequency, changing.-The frequency of a single-phase current is doubled by means of two thermionic valves connected in parallel as shown in Fig. 1, the grids G of the valves being fed with two pulsating negative tensions of the fundamental frequency with a phase difference of half a period. These tensions are obtained from a battery C and the secondary windings B, B' of a transformer whose primary winding D is fed with current of the fundamental frequency. The anodes P of the valves are connected to the cathodes F through the primary winding S of a transformer and through a battery or directcurrent generator A. Pulsating current of twice the fundamental frequency flows through the winding S and is used to produce secondary currents in windings E, E<1> for a further multiplication of the frequency. The multiplication may be repeated several times, the same batteries A, C being used for each multiplication. When the desired frequency has been obtained, the current is amplified by the arrangement shown in Fig. 2. This arrangement comprises a pair of large thermionic valves V, V<1> and a pair of batteries A, A<1> connected as shown to the coil or resistance R in which the current is utilized. The grids G are fed by tensions of the multiplied frequency differing in phase by half a period. Specification 154,720 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the batteries may be replaced by sources of alternating current, a second oppositely-connected valve being placed in parallel with each of the valves V, V<1> in order to utilize both half-waves of the alternating currents. For n-phase currents, an arrangement with 4n valves is used. This subject-matter does not appear in the Specification as accepted.
