Title: Improvements relating to supplementary charges for internal combustion engines, and to apparatus for supplying them
IPC: F02M25/022
Filed: 1925-08-05
Abstract: 260,676. Kelty, H. A. Aug. 5, 1925. Spray carburettors ; vaporizers, external.-A charge consisting of the vapours of alcohol and water with or without air is admitted to the induction pipe to supplement that from the usual carburettor, or alcohol alone may be supplied to act as a carbon remover. A gasoline tank 2 is connected by a pipe 2<a> with the carburettor 8 which supplies the usual mixture to the cylinder of the engine 3 through a manifold 7. The device for producing the supplemental charge consists of a casing 9 secured either to the dashboard, or to a bracket 58 on the engine by means of a strap 56, and enclosing a heated container 14, Fig. 3, for the alcohol and water. The space 13 between the casing and container is connected with the exhaust pipe 6, Fig. 1, through a pipe 10 provided with a valve 20, Fig. 3, adapted to be actuated by a thermostat 25. Excess pressure in the space 13 is prevented by a hinged relief valve 19<a> loaded by a spring 22. The container 14 is secured by a flange to a cover 15 of the casing 9 and into the cover are inserted three pipes 27, 31 and 41. The pipe 27 leads to the manifold 7 between the carburettor 8 and the cylinders, the pipe 31 is of U-shape, has a valve 37 and extends downwardly outside the casing, Fig. 1, its lower end being open to the air, and pipe 41 leads from a tank 40 containing a mixture of alcohol and water. The inlet of the mixture to the container 14 is controlled by a valve 47 actuated by a float 52. A baffle 54 is interposed between the pipes 31 and 41 and serves as a stop for the float. The container 14 is intially filled to the desired level with a liquid consisting of equal proportions of alcohol and water, but as the alcohol evaporates at a faster rate than the water, the mixture in the tank 40 has a preponderance of alcohol, say 60 to 80 per cent. The initial mixture for the container 14 is drawn in through the pipe 31 which may also be employed to admit alcohol alone over the liquid already in the container or alternatively the container may be filled with alcohol. The strength of the mixture drawn through the pipe 27 may be varied by opening or closing the valve 37.

Title: Improvements in the manufacture of sulphur dioxide and apparatus for use therein
IPC: C01B17/54
Filed: 1922-07-19
Abstract: 205,224. Houseman, C. R., and British Oxygen Co., Ltd. July 19, 1922. Sulphur burners.-Sulphur dioxide is produced by burning a film of sulphur in oxygen in such manner that the film of sulphur is kept in contact with the gases after passing the point at which the oxygen is supplied, while heat is removed so that fumes of sulphur vapour are avoided. The apparatus shown comprises a drum A which rotates so as to dip into molten sulphur D in a casing C, the space x at the top between the casing and drum being narrow. Oxygen is supplied by pipes c<2>and escapes by a long slit or row of perforations E, the supply pipe being covered by a cover c. A cooling agent such as water F is provided inside the drum A which is provided with vanes a to facilitate the cooling effect. Vapour generated within the drum escapes through the hollow shaft B upon which it is mounted. The sulphur dioxide escapes by a pipe c<2>. The speed of rotation of the drum is arranged so that the film of sulphur is just molten when it reaches the liquid sulphur again.

Title: Double-acting friction element freewheel
IPC: F16D41/10
Filed: 1963-05-20
Abstract: 988,919. Ratchet clutches. FICHTEL & SACHS A.G. May 20, 1963 [May 18, 1962], No. 19939/63. Heading F2C. A double-acting ratchet clutch, transmitting drive in either direction of rotation and allowing over-running in both directions, has sprags between inner and outer ring-shaped races, a control ring engaging one end of the sprags arid coacting with a light friction brake to tilt the sprags one way or the other according to the direction of drive. In one form, sprags 3 are nipped in recesses in a resilient cage 4 of plastics, steel &c. which biases them radially outwards to engage frictionally with an outer clutch ball 2, the inner ends of the sprags passing through slots 7 in a control ring 8 surrounding an inner race or shaft 1. The control ring 8 can be rotated against the drag of a light friction brake which, in the form shown, is a stirrup spring 9 carried on a stationary peg 10 and engaging an extension of the control ring. According to the direction of rotation of the race 2, the sprags 3 are tilted one way or the other to wedge between the races, and thus transmit drive to the inner race 1. Over-running of the inner race 1 is permitted in either direction. The sprags 3, Fig. 5, have grooved edges 6 for engagement by tongues at the ends of the recesses in the cage 4. In a modification, Figs. 3, 4 (not shown), in which the inner race drives to the outer race, the friction brake is a flexible spring wound round the extension of the control ring, which latter lies against the outer, instead of the inner, race.

Abstract: 1,175,984. Processing seismic data. MOBIL OIL CORP. 3 May, 1967 [3 May, 1966], No. 20582/67. Heading H4D. In the processing of a seismic signal I(t) it is known to auto-correlate I(t) over a time interval t 1  to t 2  and to derive (e.g. by an analogue or digital computer) from the auto-correlation function the characteristics required for an inverse filter 24; it is stated that the " perfect " inverse filter may give rise to an undesired output signal component of large amplitude; according to the invention, the inverse filter is " stabilized " against such an event by effectively introducing white noise. In the first embodiment such introduction is made by adding a pulse from source 17, the pulse amplitude being between 0À1% and 10% of the peak value of the auto-correlation function. In another embodiment noise from a generator is added to input signal I(t), Fig. 9 (not shown). In the first embodiment a band-pass filter 26, see also Fig. 7 (not shown), is added to allow for the characteristics of the inverse filter at low and high frequencies.

Abstract: 1,127,090. Magnetic-head positioning. MOTOROLA Inc. 4 May, 1967 [18 July, 1966], No. 20777/67. Heading G5R. A cam, for raising and lowering a magnetic head on a tape-player into correspondence with different tracks on a tape in a cartridge, is rotated by two pawl members acting on a ratchet wheel coupled to the cam, the pawl members being resiliently biased together and being coupled to the armature of a solenoid which is automatically first energized on completion of play of a track on the tape, and then de-energized, so that the head is automatically positioned to play another track. As shown in Fig. 2, a stereo tape-player 10 has a capstan shaft 20 mounted in a housing 22 and a tape-head 12 mounted in a head bracket 14 having integral with it a cam follower 16. The bracket 14 is secured to a pantograph linkage including pivot rods 17, 18 and a spring (not shown) which serves to urge cam follower 16 into contact with a cam 19. The cam 19 has a plurality of different surfaces each associated with different tracks on the tape. When the end of a set of tracks is reached on the tape, an aluminium strip moves across a set of contacts (not detailed) to energize a solenoid 39, whose armature 37, Figs. 3 and 4, is linked to two pawls which engage a ratchet connected to cam 19. Action of pawl-and-ratchet mechanism.-The position of the parts before movement is shown in Fig. 3. When the solenoid is energized, the armature is withdrawn to the left, whereupon actuating projection 44 on the upper pawl 32 moves tooth 50 on ratchet 42 to the left by an angular distance of one half tooth; at the same time locking portions 45, 48, on pawls 32, 33 respectively, engage teeth 52, 54 respectively to prevent counter rotation of the ratchet: this is the position of Fig. 4. When the solenoid is de-energized, a spring (56, Fig. 2), urges the armature to the right once more, whereupon actuating projection 47 on lower pawl 33 moves tooth 58 to the right by an angular distance of one half tooth until a position equivalent to that of Fig. 3 is reached but with the ratchet rotated by one tooth angle. The pawls are biased towards each other by a spring 40; the ratchet rotation is counter-clockwise. Vertical adjustment of cam 19 and pawl 42 may be effected by movement of their shaft 64, Fig. 2, by an adjusting screw 65.
