Abstract: 204,391. Marks, E. C. R., (Herman, R., Herman, S. J., and Herman, N. B., (trading as Diamond Power Specialty Co.)). June 27, 1922. Cleaning, fluid-pressure processes for.-A blower tube for projecting jets of cleaning fluid over the boiler interior is provided with means to prevent its longitudinal movement in one direction unless accompanied by a partial rotation at a number of predetermined points in its path. The member 24, Fig. 3, by which the blower tube 9 with its distributing nozzles 12 is actuated, has a number of circumferential channels 35 connected by longitudinal channels 36 arranged in staggered relation around its periphery, and is screwed to one end of a rod 8 attached to the blower tube 9. This end of the rod also carries, in a casing 22 attached to the smoke-box door 4, a collar 26 shaped as shown in Fig. 7. A spring-pressed pawl 29, housed in the casing 22, normally retains the blower tube in its retracted position, but, on rotation of the operating member 24, a projection 38 on the collar bears against the pawl and stops the rotation in such a position that the member 24 may be pushed directly forward one step in its path by the pawl 29 riding over the bevelled part 34 of the collar, until the pawl strikes against the square forward edge of the first circumferential channel, when the blower tube may be further advanced by giving it partial rotation to bring the successive staggered channels 36 into register with the pawl 29. The rearward edges of the circumferential channels are bevelled so that the blower tube may be directly retracted.

Title: Improvements in or relating to methods of increasing the rate of flow in diffusion separating and diffusion coefficient measuring devices
Inventor: LANGE FRITZ
IPC: G01N13/00
Filed: 1966-05-09
Abstract: 1,141,615. Diffusion. DEUTSCHE AKADEMIE der WISSENSCHAFTEN ZU BERLIN. 9 May, 1966, No. 20459/66. Heading B1X. To increase the rate of flow in diffusion processes in which a medium (gas or liquid) diffuses within a zone formed by networks, lamellan systems, or filters into another medium (gas or liquid respectively), the media are introduced and discharged into and from the zone, or the zone is moved towards and away from the media. The arrangement forming the zone may consist of flexible material, and variation in volume of it can cause the required pulsations. The figures illustrate the process occurring in a capillary 2, in the case of the diffusion zone being constricted as a capillary system. The space 1 is filled with an aqueous dyestuff solution and the capillary 2 and space 3 are filled with water into which the diffusion takes place. When the dyestuff is forced into the capillary by a plunger device (not shown) a parabaloid 4 of the dyestuff forms and diffusion takes place in the direction of the arrows. When the dyestuff parabaloid is withdrawn into space 1, a water parabaloid 6 is formed and dyestuff particles diffusing into this water parabaloid are forced into the space 3 on the next action of the plunger.

Abstract: 687,847. Gas turbine plant. ROLLS-ROYCE, Ltd. Sept. 21, 1950 [Aug, 5, 1949], No. 20473/49. Class 110(iii) A fuel system for a gas turbine engine comprising a shut-off cock to control the fuel supply to the engine during starting has a manually operated selector lever connected with the shut-off cock which in a first position prevents opening of the cock and in the second position permits opening of the cock, and a device responsive to a selected engine rotational speed to control the opening of the cock when the lever is in the second position. A shut-off cock 24, Fig. 2, in the fuel supply line 23 of a gas turbine engine is operated by a hand lever through a push-pull rod 42 which has a lost motion connection 39 to the operating arm 38 of the shut-off cock. The arrangement is such that when the hand lever is moved from its closed to its open position, the spring 41 is compressed and the operating arm 38 loaded in the sense of opening. The cock 24 is held in the closed position by a detent 37 engaging a notch 37a. When the engine reaches a predetermined rotational speed, a centrifugal governor 33, Fig. 3, mounted on the drive shaft of the electric starting motor 25 closes the contacts 34a of a switch 34 and energises the solenoid 36. This releases the detent 37 and allows the cock 24 to open. In a modification, Fig. 4, two shut-off cocks 24, 43 are arranged hydraulically in series in the fuel supply line 23, the cock 43 being operated by the hand lever 46 through a rod 45 and the cock 24 by the solenoid 36. The operating arm 38 of the cock 24 has a lost motion connection 47 with the rod 45 so that the cock 24 cannot be opened when the cock 43 is closed. The cock 24 will be closed when the cock 43 is closed. The starting motor is mounted inside a structural member connecting the compressor and turbine. In a modification, the cock 24 is spring loaded into its open position and arranged on energisation of a solenoid to be closed and the cock 43 manually operated. When the starting motor is energised, the solenoid is also energised and the cock 24 closed. When the engine reaches the predetermined speed, the governor breaks the circuit and the spring moves the cock 24 to the open position. A torch ignition is energised and fuel supplied to it when power is supplied to the starter motor.

Abstract: 1303417 Speech recognition SOC LANNIONNAISE D'ELECTRONIQUE 19 April 1971 [30 Jan 1970] 20796/71 Heading G4R [Also in Division H3] A speech analyser employs a set of digital filters to analyse the phonemes in a spoken word. Each data word representative of a portion of the spoken word is applied to selected ones of the filters, the parameters of these selected filters being set so that the filters have a transfer function suitable for the analysis of a particular phoneme. The filters selected, and the parameters, are changed cyclically so that the filters are suitable for the analysis of n phonemes in turn. The parameters are selected according to the speech characteristics of the speaker. The speech waveform is sampled, the samples passing to an analogdigital converter which provides digital signals representing the frequency variation of the successive samples. The signals pass to a store having a capacity equivalent to the duration of about one phoneme. The signals pass from the store to selected digital filters via a switching circuit. In the case of a language having 36 phonemes the switching circuit selects in turn 36 different combinations of filters selected from a group of 16 filters-as described the filters are Lerner filters. In synchronism with the switching of the filters the parameters of the filters are altered under the control of a store containing the parameters required to set the selected filters, for each position of the switch, to present a transfer function suitable for the analysis of a corresponding one of the phonemes. The filters provide digital signals indicative of the phonemes. To accommodate different speakers the contents of the parameter store may be replaced by parameters pertinent to the particular speaker.
