Title: Improvements in carburetters
IPC: F02M3/09
Filed: 1932-08-25
Abstract: 390,710. Spray carburetters. BARBAROU, M. J. B., 28, Boulevard d'Argenson, Neuilly-sur-Seine, France. Aug. 25, 1932, No. 23771. Convention date, Aug. 27, 1931. [Class 7 (iii).] In order, particularly in aircraft engines, to prevent fuel from being drawn through the slow-running duct when the throttle is closed, the said duct is provided with a valve, adapted to be actuated, through elastic means, from the throttle valve or independently, whereby the slow-running duct can be closed and the engine stopped. The slow-running system comprises a well 5 into which dips a tube 7 which communicates through passages 11, 12 and aperture 13 with the induction passage 2 at the edge of the throttle valve 4. The aperture 13 is always slightly open even in the completely closed position of the throttle valve. The upper end of the tube 7 terminates in a plug 9 having a bore 14 in which is adapted to slide the stem 15 of a needle valve 16 which can seat on the upper end of the tube. The upper end 17 of the valve has a slot 18 through which passes a pin 19 attached to a pair of links 20 connected by a lever 22 and rod 24 to the throttle or an independent control. The valve is urged towards its closed position by a spring 25 bearing against a collar 26 and fixed abutment 27. The needle 16 is first raised to provide slow-running fuel, and then the throttle is opened. During slowing down, the throttle is moved to closed position, but needle 16 is still open thus producing slow-running conditions. Further closing movement cuts off the slow-running fuel and definitely stops the engine.

Title: Decimal encoder
IPC: H01H19/58
Filed: 1965-06-08
Abstract: 1,102,622. Shaft encoders. PERKINELMER CORPORATION. 8 June, 1965 [8 June, 1964], No. 24205/65. Heading G4H. In a shaft encoder the pattern of contacts is designed for reproduction by printed circuit techniques by having only five groups of ten contacts for the units track 100, Fig. 1, the interconnections between corresponding ones of the groups passing through the spaces between the groups, and two wipers 142, 145 are provided, energized alternately from the tens track so that a wiper passing over the interconnections between the contact groups is not energized. The tens track is in two portions 110 and 120, contacts 30, 50 &c. being for odd tens digits and contacts 40, 60 &c. for even digits. They are energized from slip-ring 130 by wipers 140 and 143, and wipers 142 and 145 are energized through the contacts 30, 40 &c.by wipers 141 and 144. Each contact has an output terminal such as 31. To prevent a false reading the unit 5 interconnection between adjacent decades is widened such that when the wiper 142 passes over an energized interconnection it is the same as that contacted by the wiper 145. The conductors are of a dimension to give overlap of outputs at the changeover between decades and buffer circuitry (Fig. 3, not shown) including diodes and transistors, gives precedence to the correct signals. The wipers are mounted on a rotatable shaft and move over a scale printed on the inside of a surrounding cylinder. A multi-turn adapter may be fitted to the shaft by an eccentric pin rotating a planetary gear whose rotation is converted to a concentric rotation by an Oldham shaft, the gearing providing a 10: 1 speed reduction. Wipers in the adapter move over a scale printed on a disc, lead and lag wipers being provided with the leading wipers energized by the 0, 1, 2, 3, 4 outputs of the previous decade and the lagging wipers are always energized, the overlap being handled by precedence circuitry similar to Fig. 3 (not shown).

Title: Improvements in wireless transmitters
IPC: H04L27/04
Filed: 1924-10-13
Abstract: 245,829. Davis, N. E., and Ditcham, W. T. Oct. 13, 1924. Thermionic modulating systems.-In a transmitting system comprising intermediate and power amplifiers energized by a master oscillator, wherein the anode voltage is derived from a common source, modulation is effected by controlling the voltage drop across a resistance inserted in such a position that the anode current of the independent-drive valve, or the intermediate amplifier, passes through it, though the anode supply to the power amplifier does not. As shown in the Figure, a master oscillator circuit D supplies intermediate and power amplifiers VI, V2. A resistance R1 in the plate circuit of the valve VI is shunted by one or more absorption valves V3, the grid potential of which is varied by means of a key F, and batteries B1, B2. When the absorption valve is made conductive the potential drop across R1 reduces the anode voltage of the valve V1 to such an extent as to stop oscillations in the aerial A. Meanwhile the load across the generator G is taken up by the absorption valve V3, thus preventing voltage surges during signalling. The valve V3 may be replaced by a suitable switch having a sufficiently high current-carrying capacity.

Abstract: 1425609 Internal combustion engines: fuel injection pumps SOC ANON DE VEHICULES INDUSTRIELS ET D'EQUIPEMENTS MECANIQUES 22 May 1973 [24 May 1972 15 Nov 1972 24336/73 Heading F1A and F1B Starting of an I.C. diesel engine is facilitated by rendering some cylinders more suitable for stating the engine, e.g. by having a smaller unswept volume to increase the compression ratio, and the others more suitable for running the engine under full power. In the six-cylinder engine shown, two cylinders, 3 and 4, act as starting cylinders. The unswept volume is decreased by reducing a chamber (10 4 ), Fig. 2A (not shown), in the top of the piston or, Fig. 2B (not shown), by reducing an injection chamber (8 4 ) in the cylinder head. Also, the inlet closure delay of the starting cylinders is reduced to 16 degrees of crank angle as compared to the 45 degrees for the power cylinders. The fuel supply to the starting cylinders is less than to the power cylinders. This may be effected by setting the starting cylinder injection pumps, e.g. 12D, to deliver less fuel than the power cylinder pumps e.g. 12P. The quantity of fuel in the delivery lines is determined by limit return valves 23D, Fig. 3, which allow a quantity of fuel represented by 24D to return to the pump during a subsequent part of the pump cycle. With an in-line injection pump the quantity of fuel delivered by each plunger may be determined by the setting of the plungers 13P, 13D relative to the rack or by modifying the upper profile of the piston. The injection lead may be changed by altering the rotational position of the cams 14D. When the pump is of the rotary type Fig. 8 (not shown) the distribution passages may be staggered to alter the injection lead. In Fig. 6 (not shown) a V-8 cylinder engine has two starting cylinders under a common cylinder head and, Fig. 7 (not shown) a flat 12 cylinder engine has three starting cylinders. In another arrangement, Fig. 10 (not shown) oriface plates restrict the air-flow into the starting cylinders.

Abstract: 1,213,242. Coating apparatus. USM CORP. 22 May, 1968 [23 May, 1967], No. 24373/68. Heading B2L. Headed screw-threaded elements are conveyed in succession past means for applying primer to the elements, means for heating said elements, and means for applying locking patches to said elements. Screwed bolts E pass in succession from a shoot 9 to the space between a pair of endless belts 6 supported on pairs of pulleys 2 and 4 axially adjustable for varying the distance between the belts. The pulleys 4 are driven by respective variable speed motors, whereby the bolts may be rotated for the application of encircling patches. The bolts first receive a priming coat applied thereto by a nozzle 60, and then pass through a groove formed in the upper surface of an insulating block 70. A high frequency induction coil 71, positioned along the sides of said groove, serves to heat the bolts. Powdered resin is then blown on to the bolts at a station R, and the bolts are finally cooled by a jet of air at a station C. At station R powdered resin in a hopper 10 is metered by the screwthreaded lower end of a shaft driven from a motor 18 via reduction gearing 19, pulleys 20, 22 and a belt 24. The metered resin is delivered by a funnel 40 to a manifold 42 having a compressed air inlet 44 at one end and a detachable nozzle 46 at the other end. The height H' of the nozzle orifice determines the number of screw threads coated, and the width of the orifice determines the thickness of the coating.

[Class 100 (i).] Sheet-registering devices.-A side registering device for printing-machines, which is especially applicable to register sheets accurately just before they are seized by grippers 26 on the impression cylinder 25, Fig. 1, of an offset printing- machine, is constructed of two independently reciprocating supports 14, 15, Fig. 3, which are actuated from adjustable cams 34, 341 on a common power shaft 32 which drives the printing-machine. The supports 14,15 are guided in bushings 55, 55<1> in side frames 11, 12 and move over a crossbar 13. The cams 34, 34<1> actuate spring-pressed levers 37, 37<1>, connected to bell cranks 40, 401, which are connected by links 44, 441 to sockets 45, 45<1> secured adjustably to the supports 14, 15. To obtain accurate adjustment of the sockets so as to set the device accurately for sheets of various widths, auxiliary sockets 47, 471 are secured to the supports and when these are secured so as to secure a rough adjustment, a fine adjustment is obtained by a micrometer screw 49 or 491 which adjusts the sockets 45, 45<1> relatively to the auxiliary sockets, the sockets 45, 45<1> being fixed in position after the fine adjustment. The supports 14, 15 carry sheet-engaging members in the form of rollers 21, 20, of which the roller 21 is mounted in a spring-pressed slide 16 which can yield relatively to a fixed slide 50 screwed to the support 14. Sheet guides 22, 23 are secured near the rollers 21, 20. The cams 34, 34<1> are set so as to bring the rollers 21, 20 into contact with the sheet on the table 52 before it reaches the cylinder, and to release it immediately after it reaches the cylinder and the grippers close on it, so that even if the sheets are not exactly uniform size, the registration will not be adversely affected thereby. The cams 34, 341 are set so that the yielding roller 20 acts in advance of the rigidly mounted roller 21. The rollers 20, 21 can be reversed in position so that the yielding roller will act from either the left or right side.

Apparatus for forming packages containing a plastic substance comprises means for pressing successive wrappers into successive pockets or moulds provided in a conveyer, the open-ended containers thus formed then being charged with the plastic substance and ejected from the conveyer pockets. Wrapper blanks 11 comprising a body portion 18 and a lid 19 are formed in succession from a web 12 by a punching device 13, a knife 14 severing the blanks from each other. As each blank is fed forward by a pair of rollers 17, a pocket-wheel conveyer 21 is rotated to move one of a series of pockets 22 to a forming station 16, the body 18 of the blank 11 being formed into a hemispherical cup by a presser member 23 engaging in the pocket. The pocket-wheel rotates stepby-step and the cups move in turn to a filling station 28 where ice-cream is extruded from a nozzle 29 and is cut off by wires 31 to form a charge 33. After the filling operation, the lid of each cup is folded over by a plough 38 and after being ejected by a plunger operated by means of a cam track 43 and roller 42, the cup is passed on to a delivery conveyer 47 by guides 46. Separate lids may be used in place of the lids 19 or the containers may be of a sufficient depth to permit the forming into a lateral seam of the, surplus material, the seam being secured by crimping if desired. Alternatively, the surplus material may be folded or twisted. Separate re-usable moulds which may be of metal, rubber or plastic may be removably mounted in the pocketed conveyer so as to be ejected with the packed charges. The plastic substance,may be contained in a hopper and formed into successive charges at the mouth of the hopper. The pocketed conveyer may be of a chain type and the wrapper blanks may be preformed. According to the provisional specifications, the presser member for forming the containers may be combined with the extrusion nozzle, the containers thus being formed and filled at one station. Specification 728,902 is referred to.
