IPC: B24B33/08
Filed: 1971-04-19
Abstract: 1290124 Grinding C W GEHRING 19 April 1971 [19 March 1970] 24168/71 Heading B3D A honing machine comprises a rotary drive 11 for a tool 10 for machining the bore or curved surface of a workpiece 6, and a torque sensitive device 12 responsive to the torque on the drive resulting from machining of the workpiece and coupled to a switch device operable to stop or stop and reverse the drive when the torque reaches a pre-adjusted limiting value. The tool 10 is mounted on a rod 9 connected through the torque sensitive device 12 to a spindle 8 on a carriage 4 slidable on vertical guides 3 to and from the workpiece 6 held by a device 5 on a machine table 7. The spindle 8 is rotatable by the drive 11 consisting of a geared motor. Because of the clearance between the holder 16 of the cutting bar 17 in the tool, the holder, in one direction of rotation of the tool is inclined in one direction. As the cutting bits 18 wear and form flats (19, Fig. 2b, not shown), the torque on the tool increases. When the torque reaches a predetermined value, the torque-sensitive device 12 acts, through an amplifier in a control panel 13 to a stop or stop and reverse the motor 11. Upon reverse rotation, the holders 16 are inclined in the opposite direction to bring a sharp edge of the flat (18) into contact with the workpiece.

Abstract: 1295176 Pipe joint L BANIDES and J DEBEAURAIN 27 Feb 1970 [27 Aug 1969] 9741/70 Heading F2G A joint between two pipes is made by aligning the pipes end to end and spaced from one another, arranging a mould consisting of a metallic sleeve around the peripheral surfaces of the pipes, the internal diameters of the ends of the mould being smaller than that of the centre of the mould, placing electrically insulating rings between the ends of the mould and the peripheries of the pipes, moulding an insulating material within the space defined between the mould, the pipes and the insulating rings, the pipes having keys on their peripheries for mechanical locking with the moulded material. The keys on the pipe peripheries are preferably notches or cuts formed by grinding chiselling or punching, and they preferably extend in non-parallel directions (i.e. longitudinally and transversely). Alternatively the pipe ends may be flared or wrought collars or independent rings may be secured thereto (e.g. by expansion of the pipe therein). The mould may also be internally keyed. Fluid tightness while casting may be achieved by joining the pipe ends with a ferrule or adhesive strip, and an insulating ring may be used to separate the pipes. As shown in Fig. 1, the mould 12 is a split casting and an agglomerated sand ferrule 11 is removed after casting material 16. In the form shown in Fig. 2 (not shown), an insulating spacer (18) is inserted between flared ends (17) of the pipes. The casting material may be thermosetting or thermoplastic or "Araldite" (Registered Trade Mark).

Title: Separation and recirculation of soot contained in the exhaust gases of compression-ignition engines
IPC: F02B3/06
Filed: 1972-04-11
Abstract: 1334472 Treating exhaust R W TEMPLEPEDIANI 11 April 1972 16520/72 Heading F1B [Also in Division B2] A separator and mixing chamber fitted to a compression-ignition engine which divides the exhaust gas from the engine into two streams, one stream containing relatively little soot and being discharged to atmosphere through a tail pipe and the other stream containing the bulk of soot and being caused to flow through a port or ports in a control valve into a mixing chamber wherein this stream mixes with fresh air being induced by the engine and is recirculated to the engine cylinders. Exhaust gas 1 enters a cyclone separator 3 tangentially, the soot particles being centrifuged outwardly so that a relatively clean core stream of gas 4 is formed which passes to atmosphere through a tail pipe 5. The remainder of the exhaust gas forms a surrounding annular stream containing the bulk of soot and passes through a port 10 in a sleeve valve 11 to a mixing chamber 9. Air induced by the engine through a pipe 8 traverses the mixing chamber which has a reduced cross-section and contains the exhaust gas via the port 10. The area of the port can be varied by movement of a lever 12 which is actuated by a servomotor responsive to signals from a photo-electric soot detector in the tail pipe. Alternatively the lever is actuated mechanically by a linkage controlling the flow of fuel from a pump to cylinder injectors, the movement of the lever being modified by an interposed vacuum or pressure capsule which senses the pressure difference between the pressure of the exhaust gas in the separator 3 and the reduced cross-section of the mixing chamber. Increased fuel-flow increases the port area, but as the engine speed rises the increase in depression in the mixing chamber acts to decrease the port area.

Abstract: 1338609 Alarm systems PLESSEY CO Ltd 22 June 1971 [29 June 1970] 31424/70 Heading G4N In a signalling arrangement comprising a plurality of lamps LP1, LP2 (e.g. on a mimic diagram), individually actuable signal channels are provided, each comprising a switching device EF in series with each lamp LP1, LP2 and a monitoring circuit M having a single conductor input common to all said signal channels and arranged to provide power for the lamp or lamps associated with the actuated switching device EF. The system may be used for fault indication in a large computer complex and comprises a mimic diagram having six separate panels each having twenty-four lamps arranged in push-type keys K, each lamp being associated with respective contacts EF which close in the event of a fault in a particular section of the computer. If contacts EF close, a small current is passed via lamp LP1 to a binary transistor amplifier 1ARB which energizes relay RB. Contacts RB2 pulsate relay RA by connecting it to an intermittent earth IE. Contacts RA1 thus pulsate relays RXA and RG so that contacts RG1 cause the particular lamp LP1 to flash. Contacts RA2 pulsate relay RXB so as to flash a beacon lamp LPC associated with the particular mimic panel. Contacts RB3 operate a bell BL. Contacts RXA1 provide a holding circuit for relay RB. The fault is acknowledged by manual operation of the push-type lamp LP1 so that contacts EOM are operated by means not described, giving a steady illumination of lamp LP1. This action releases the other relays in the monitoring circuit M.

Abstract: A hardware-efficient transceiver. The transceiver includes a digital circuit for converting baseband signals to intermediate frequency signals. A signal source provides a first periodic signal of a first frequency. A direct digital synthesizer provides a second periodic signal of a second frequency from the first periodic reference signal. An upconverter circuit digitally upconverts the baseband signals to digital intermediate frequency signals using the second periodic signal A digital-to-analog converter converts the digital intermediate frequency signals to analog intermediate frequency signals using the first periodic signal. In the transceiver implementation, the digital circuit upconverts a first transmit signal from a first frequency to a second frequency in response to the second periodic signal and provides a digital transmit signal in response thereto. A second circuit is provided for converting the digital transmit signal to an analog transmit signal. Transmit and receive circuitry are provided for transmitting the analog transmit signal and receiving an analog receive signal, respectively. In a specific embodiment, the analog receive signal is digitally downconverted to provide a digital receive signal in response to a second periodic signal. A significant feature of the invention resides in the provision of the first and second periodic signals with a single local oscillator. A direct digital synthesizer is included for generating one of the reference signals from the output of the local oscillator. The transmit circuit includes a delta-sigma digital-to-analog converter having the first periodic signal as an input The delta-sigma digital-to-analog converter has a low-bit digital-to-analog converter and a delta-sigma modulator. In the illustrative embodiment, the low-bit digital-to-analog converter is a 1-bit digital-to-analog converter and the delta-sigma modulator is a sixth order delta-sigma modulator. The delta-sigma modulator includes amplifiers with approximately the following gains: 3/2, -3/4, 1/8.
