Patent GB-125167-A (GB)
IPC: F02B3/00
Abstract: 125,167. Ricardo, H. R. June 27, 1916. Four-stroke-cycle engines.-In a multi-cylinder engine, one end of each cylinder acts as a pump for the compression of air, which may be cooled, for scavenging and adding to the normal charge. Each cylinder is supplied with an additional charge from its own pump space and with a scavenging charge from the pump space of another cylinder. In the four-cylinder engine shown in Fig. 2, the pump ends of the cylinders are cross-connected to the combustion spaces by pipes H which deliver through valves timed to open when the corresponding piston has completed 30 to 50 per cent of its exhaust stroke. The extra charge enters the combustion space at the ends of alternate out-strokes through piston-controlled ports J. Valves may be located in the passages L to prevent air entering an adjacent combustion chamber at the termination of the working stroke. Cooling chambers may be provided in the pipes H and the compressed air may be supplied from a separate blower or pump.

Title: Closed loop engine controls pipe joint
IPC: F02D41/10
Filed: 1974-03-21
Abstract: 1429414 Automatic control of speed BENDIXCORP 21 March 1974 [29 March 1973] 12608/74 Heading G3R [Also in Division F1] The roughness (cyclic speed fluctuations) of an internal combustion engine is regulated to a desired level by controlling the fuel delivery to the engine, the air-flow to the engine being pre-set. As shown, the fuel supply to internal combustion engine 10 is controlled by system 12 in which an engine speed sensor 68 generates a signal whose frequency is dependent upon the engine speed. A filter in circuit 70 passes the range of frequencies from sensor 68, these signals being differentiated to form a roughness signal that is compared at 76 with a predetermined threshold. The comparator output is integrated and used by air/fuel control 60 to decrease or increase the engine fuel supply according to whether the roughness is above or below, respectively, the threshold at which harmful constituents in the engine exhaust are reduced. Under certain conditions e.g. accelerating or decelerating the output of comparator 76 may be replaced by a pre-set bias see Fig. 3 (not shown) to allow the engine to run rich, the comparator output being inhibited when the low frequency components of the filter output exceed a given threshold or when this threshold is exceeded by the second differential of the filter output.

Abstract: 455,685. Semi-rotary engines. COFFMAN, R. A., 4733, Center Avenue, Pittsburg, U.S.A. April 23, 1935, No. 12683/36. Divided out of 455,630. [Class 110 (ii)] An engine, used for starting internal-combustion engines, comprises an oscillating vane attached to a shaft 7, which is keyed to an inner driven shaft 17. A pin 23 in the latter bears against a fixed cam 30 to move the shaft 17 axially, and cause teeth 42 on the shaft to mesh with teeth 43 on the driven engine shaft 44. A spring 8, attached to the driving shaft 7 and to the casing, returns the shaft and its vane at the end of a stroke. A cartridge in an exterior chamber, is fired, and the gases flow to a chamber 491, and then through a grating 51 to press against the vane in the working chamber. Exhaust gases pass through passages 60, 61, 59, 57. A frangible partition 58 will break and permit gases to pass from a passage 55 to 57, if an excessive pressure is set up in 55. The exhaust valve 63 has notches 68 into which a detent 64 is admitted. The oscillating vane at each end of its stroke, strikes the end of the exhaust valve, as in the embodiment shown in Fig 4, where a vane 107 strikes the end 213 of the exhaust valve, to open the latter at the opposite end. In this engine, the driven shaft is geared to the driving shaft 106, to speed up the former during its axial movement into clutching position. A rotary carrier containing cartridges is provided with means to advance the carrier angularly, after each explosion. A conduit 226 leads exhaust gases to a duct 227 to be used in ejecting a spent cartridge. An oil sump 105<1> is provided for splash lubrication. A hole 105a vents the back of the chamber 105 to the atmosphere.

Title: Improvements relating to ratio detectors for angle-modulated signals
IPC: H03D3/10
Filed: 1957-04-23
Abstract: 859,051. Frequency discriminators. TELEFUNKEN G.m.b.H. April 23, 1957 [April 21, 1956], No. 12859/57. Class 40(5). In a ratio detector an inductance 10 (Fig. 1) is included in the path supplying to the centre tap of the secondary tuned circuit 2 a push-push voltage for the rectifiers 4, 5, to compensate for phase variation at the output of the secondary circuit due to the asymmetry of capacity variations produced in the rectifiers by any amplitude modulation in the applied F.M. signal. The inductance 10 must be separate from the leakage inductance of the tertiary winding 3 so that it can be adjustably set to a value independent of the ratio of the push-pull to push-push voltages applied to the tuned secondary, as by a small screw core, and may be decoupled from the primary and secondary coils by arrangement at right angles to them. The primary circuit 1 is initially slightly mistuned to allow for the introduction of the inductance 10. Linearizing resistors shown in dotted line may also be used. The coils 3, 10 may be other than series connected. In Figs. 2 and 3 the coil is inserted in series with capacitive coupling 12, or 13, 14, between the primary and secondary circuits.

Title: Satellite communication system
IPC: H04B7/185
Filed: 1970-03-18
Abstract: 1282789 Radio signalling INTERNATIONAL STANDARD ELECTRIC CORP 18 March 1970 [24 March 1969] 13057/70 Heading H4L In a satellite communication system means are provided at each ground station for maintaining constant the transit time of the signal path between the satellite and the ground station. The system may be used with synchronous satellites, or with non-synchronous satellites in which case if facilitates the transfer of communications from one satellite to another if the equipment at the ground station is duplicated. As shown in Fig. 1, data bits from source 6 in station 1 are supplied to a buffer store 9 in a variable time delay system 8, delayed under the control of a circuit 14 and transmitted at a carrier frequency F1 via transmitter 10 to a satellite repeater 2. This signal is returned at a carrier frequency F2 by the satellite, received by a monitor receiver 15 and supplied to the delay control circuit 14. The input signal from 6 is also supplied to a buffer store 13, delayed under the control of a signal from 14 and compared at 14 with the signal from receiver 15 by auto-correllation techniques. By this means the delays imparted by stores 9 and 13 are adjusted in equal and opposite directions to maintain the transit time of the signal path to the satellite constant. Data signals from terminal 3, which has similar delay adjusting equipment is transmitted on carrier frequency F3 by transmitter 10a to the satellite and retransmitted on carrier frequency F4 to the receiver 16 in station 1. The output of receiver 16 is supplied to a buffer store 17 and delayed under the control of a signal from 14 which is the same as that controlling buffer store 9, whereby the return path from the satellite is made equal to the out-going path, the delayed signal supplying a utilization device 19. In a non-synchronous satellite system it will be necessary at some time to change over from satellite 2 to satellite 4 and just prior to this the switch 29 is moved to position 30 so that the output from source 6 is also coupled to the duplicated variable time delay system 8b whereby the signal transit time of the link between station 1 and satellite 4 is made equal to that between station 1 and satellite 2. When this has been established, switch 30 is moved to its centre position, the output of data source 6 is switched over to contact 7b and switch 18 is changed over so that satellite 2 is no longer in use.

Abstract: 861,569. Billet piercing; extruding. HYDRAULIK G.m.b.H. April 24, 1958, No. 13108/58. Class 83 (4). An hydraulic extrusion press for metal tubes has a billet piercing mandrel 3 which is coupled by remote control to the main piston 7 for performing the piercing operation. A billet inserted into the container 11 is first compressed by both the press ram 1 and mandrel 3 which are advanced together by piston 7 and pistons 14 acting on a crosshead 6, Fig. 3 (not shown). The ram 1 is then retracted by rods 35 whilst the mandrel 3 is maintained against the billet by fluid pressure admitted to cylinder 17. Coupling bolts 18, 19 carried by the main piston 7 are then moved inwardly to engage behind a collar 23 on the mandrel carrier 15, by pistons 21 actuated hydraulically through remote control and the main piston 7 is again moved forwardly to force the mandrel through the billet. The coupling bolts are then released and the billet is extruded by the ram 1 through the die 12 to form a tube whilst the mandrel is maintained stationary by a device 26, Figs. 5, 6 (not shown). Withdrawal cylinders 30 are provided. for the mandrel.

Title: Improvements in and relating to installations for removing dust from dust-laden air,flue gases and so forth
IPC: B04C5/28
Filed: 1936-05-08
Abstract: 466,983. Cyclone separators. BUELL COMBUSTION CO., Ltd. (Tongeren, H. van) May 8, 1936, No. 13115. [Class 23] Small cyclones 1 are arranged in pairs of parallel rows with common inlet passages 3 between the rows of each pair ; the inlet passages are of constant width and decreasing height. This is more compact than the arrangement of the cyclones in two converging rows with an inlet passage of constant height and decreasing width. Valves 6 may be provided at the front of the common inlet passages. Separate dust hoppers may be provided for each pair of rows, or, a single hopper for several pairs. In the latter case, back flow from one pair to another is prevented by pendulum valves or doors which open to permit the passage of dust only when sufficient dust has accumulated to overcome the loading of the valve. In the arrangement shown, air to be cleaned enters at 12 into a chamber 11 and air carrying the largest particles goes forward to a throat 15 and thence to separators 13 suited to deal with the larger particles. The remainder of the air passes between blades 16 to a chamber 17 and thence to the inlet passages 3. The chamber 11 has a movable wall 18 which is used to reduce the size of the chamber as the flow of gas is reduced. The space behind the wall 18 may communicate with the chamber 17 and then the greater gas pressure which obtains in the chamber 11 tends to press the wall 18 outwards. As this difference of pressure diminishes with the gas flow it can be used to produce automatic movements of the wall 18 which may be supported against the resultant gas pressure by a suitable spring or by a weight-supporting cord. The movement of the wall 18 may be used to operate the valves 6 also. Servomotors may be used. In an alternative construction, the wall carrying the blades 16 is movable automatically under the direct difference of pressure existing in the chambers 11 and 17. Fig. 13 shows a form of the separator described in Specification 390,053 in which dust extracted by way of a slot 38 passes down an external conduit 39 and enters the cyclone again through slot 40. The channels 39 are provided by the triangular spaces between the several cyclone inlet scrolls shown in Fig. 6.

Abstract: 330,706. Jackson, L. Mellersh-, (Hartford-Empire Co.). April 27, 1929. Gathering.-Relates to apparatus for circulating molten glass in a gathering-pool or forehearth, particularly for use in connection with suctiongathering machines. According to the invention, the glass is moved by an impeller the lower end of which is submerged in the glass and is moved in two intersecting paths at right angles to one another. The apparatus comprises a forehearth 7, Fig. 2, having at its front end an opening 11 through which a suction head 12 is inserted periodically to gather glass at the point 41. The roof 7a of the fore hearth has an opening for an impelling- rod 16 which dips into the glass and is so mounted and moved that the centre of its lower end describes a horizontal orbit 40, Fig. 1. The impeller is carried by an arm 18 pivoted to a shaft 19 which is journaled in a bearing bracket 21 and has crank arm 19<a>. The crank arm carries a roller 22 that engages a cam slot in a barrel cam 23, so that rotation of the cam swings the impeller in a direction transverse to the length of the forehearth. The arm 18 is also connected bv a link 39 to a lever 32 carrying a roller which rests on the surface of a cam 30, a spring 35 being provided to keep the roller in contact with the cam. Rotation of the cam swings the impeller in the direction of the length of the forehearth, but the cams 23 and 30 are geared with one another in such a manner that the transverse and longitudinal movements of the impeller alternate and the centre of its lower end moves in the path 40. In a modified construction, the impeller is reciprocated vertically instead of being swung transversely, so that the movement of its lower end takes place in a vertical plane. The impeller may be cooled by water circulated through a core.
