Title: Improvements in the feeding of abrasives to glass surfacing tools
IPC: B24B57/00
Filed: 1952-05-13
Abstract: 696,807. Grinding and polishing glass. GLACERIES DE LA SAMBRE SOC. ANON. May 13, 1952 [May 19, 1951; Dec. 13, 1951], No. 12147/52. Class 60. A ribbon 3 of glass passing through a grinding and polishing apparatus is supplied with an atomised mixture of abrasive and water. The mixture is drawn by a pump 9 from a sump 17 and fed to pipes 10, 11 fitted with atomisation nozzles 12. During inoperative periods the mixture is circulated at a rate which is just sufficient to prevent obstruction of the nozzles. Jackets 14 and a duct 16 form a return path to the sump 17. Vapour or compressed, humidified air may also be supplied to the glass through the nozzles 12 or, alternatively, by pipes 18, 19 connected to a main duct 15. Similar apparatus, without the return flow system, may be used to supply the upper surface of the ribbon. Where a set of surfacing tools is mounted on a transversely reciprocating beam 26, Fig. 5, each tool is fed from a sump 27 fitted with an agitator gear driven from the tool spindle, and a compressed air supply 34 for the atomisers is connected to the beam by a flexible pipe 33. The air supply to each atomiser is controlled by a spring-closed valve 36 which is opened by engagement with an adjustable stop 37 at the end of each reciprocation of the beam. The stops 37 may be moved to an inoperative position. In the case of a fixed beam, the valves may be operated by cams on a crank and connecting rod mechanism. The atomisers may be of the kind in. which the escape of compressed air sets up a negative pressure at the outlet end of a discharge tube for the abrasive mixture, or of the kind in which compressed air is fed to the sump to reduce the density of the mixture at the inlet end of the discharge tube.

Abstract: 900,820. Controlling apparatus photo-electrically. GRUBB PARSONS & CO. Ltd., Sir HOWARD. March 18, 1960 [April 10, 1959], No. 12298/59. Class 40 (3). [Also in Group XX] A fixed angular relationship is maintained between two movable members by servomotors controlled by an autocollimator. A large radio or optical telescope with an azimuth-elevation mounting has attached thereto an autocollimator tube 5, Fig. 1, and is controlled in equatorial co-ordinates by a master unit with an equatorial mounting to which is attached a plane mirror 7. Light from the source 2 is focused on an adjustable diaphragm 4 to form a virtual source of adjustable size which is imaged by a lens 6 after reflection from mirror 7 on a rotating semicircular mirror 9. If the telescope is correctly aligned relative to the master unit the image falls on the axis of rotation, but when it is off this axis the detector 8 produces an A.C. signal with phase dependent upon the angle by which the plane of mirror 7 departs from that desired. The phase of the signal is compared with reference signals in quadrature supplied by the motor 10 to determine the error in azimuth and elevation. These signals energize respective servomotors 18<SP>1</SP> and 18<SP>11</SP>, to adjust the telescope. The master unit is positioned by making stellar observations with a sighting telescope through a non-reflecting path on mirror 7. Alternative means of illumination are described (see Group XX).

Title: Improvements in the removal of carbon monoxide from impure hydrogen or gaseous mixtures containing hydrogen
IPC: C01B3/16
Filed: 1944-07-01
Abstract: <PICT:0586758/III/1> In a process for the removal of carbon monoxide from impure hydrogen or gaseous mixtures containing hydrogen by treating with steam in the presence of a catalyst in a plurality of stages, the gas stream mixture leaving one stage of carbon monoxide conversion passes directly without cooling to an absorber, round which is circulated a hot aqueous solution of an absorbent, and thence directly to a succeeding conversion stage.  In one embodiment, the gaseous mixture is mixed with steam, heated in heater 3, and passed into a converter 4 containing one or more layer of catalyst 5 such as a promoted iron oxide type.  The resulting gas-steam mixture is passed directly to an absorber 6 containing a solution of alkali hydroxide, in which the sensible heat of the entering gaseous-mixture is utilised to saturate with water vapour the exit gaseous-mixture which is passed, with addition of further steam if necessary, to a second heater 8 and converter 9.  In a modification, the sensible heat of the converted gas-steam mixture leaving the last stage of conversion is utilised for heating water which is subsequently employed for heating and saturating the initial gaseous mixture, the amount of steam added being regulated by allowing a part of the gaseous mixture to pass through a saturator and mix with the part which is bye-passed before proceeding to the first stage of heating and conversion.  Where a solution of organic absorbent, such as ethanolamine, is employed, a heat exchanger is incorporated in the circuit, by means of which partially spent absorbent leaving the absorber is heated by the regenerated or partially regenerated absorbent leaving the regenerator to be recirculated to the absorber after suitable cooling.  The organic compound and alkali hydroxide may be used as absorbents in the initial and final stage or stages of conversion respectively.  The absorbers may be suitably insulated against thermal losses so that the amount of water evaporated increases on proceeding from the first to the last stage of conversion.

Title: Digital coding of angles
IPC: G01D5/247
Filed: 1975-03-26
Abstract: 1498829 Measuring angular position SOC D'ETUDES, RECHERCHES ET CONSTRUCTIONS ELECTRONIQUES 26 March 1975 [28 March 1974] 12711/75 Headings G1A and G1N (A) A digital angle coder comprises a fixed reading head TF, a reading head TMO relatively movable about a first axis through the angle to be coded, a member 5 rotatable at constant speed about an axis coincident with the first and carrying a plurality of marks adapted to be read by the reading heads which in co-operation therewith produce two series of read-mark signals, and angle-detector means for accumulating the time intervals between the signals of one series and the signals of the other series during one or more complete revolutions of the member 5. The heads TF, TMO may be magnetic reading heads and the marks recordings on a magnetic track. To compensate for any misalignment of the two axes a second movable reading head TMA is provided and the mean of the readings of the two heads T MO , T MA  is taken. In use, e.g. in a theodolite, the phase control circuit 15, Fig. 2 and origin setting 16 are activated and with the arm 6 in the first position the mean phase displacements read by circuits 23, 33 are stored in memories 24, 34. During rotation of the arm 6 to the second position the difference in numbers of pulses read by the fixed and moving heads are registered by the reversible counters 22 and 32, together with the sign of angular separation, and provide a coarse measurement of the angle. Pulses coincident in time are separated by anti-coincidence circuits 21, 31. A final mean phase displacement is then taken and subtractors 26, 36 supply the difference between this and the stored initial value to the circuit 18. Circuit 18 provides the mean of the fine measurements of angle from circuits 26, 36 and the mean of the coarse measurements from circuits 27, 37. In a second embodiment, utilizing optical methods, the fixed reading heads TFO, TF180 each comprise a photo-emission cell 420, e.g. an LED, a reflective grid 421 or 423, and a photo-receptive cell 422, e.g. a phototransistor. Coincidence between the marks on a grid with similar reflective marks 51 on a rotating disc 50 of low or zero reflectivity material causes a minimum in reflected light. For coarse measurements the auxiliary fixed head T 1  and the auxiliary moving head T2 read single marks 53, 54 respectively on the disc. The speed of the disc may be related to the frequency of the counter clock 1 or the clock may be enslaved to the disc speed which is maintained substantially constant.

INTERNATIONAL BUSINESS MACHINES CORP 20 March 1972 [5 April 1971] 12867/72 Heading A4X A resilient member, e.g. a plastics credit card 11, is mounted at its corners in slits 30 in a supporting member, e.g. a mailer card 13, by an apparatus having a ram 60 that on extension contacts card 11 and forces it against fulcrum points 76 of a stationary anvil 71 for progressively bowing the central portion forwardly and causing the edges 11a to pivot rearwardly so that the corners contact card 13 outwardly of slits 30. The corners then move inwardly and cross the outer edges of the slits 30, at the same time deforming card 13 rearwardly to open the slits. When ram 60 is retracted, the card 11, under its inherent resiliency, snaps to its normal flat condition and this causes edges 11a to move outwardly and cause the corners to tuck under the outer edges of the slits. Credit cards 11 are incrementally advanced horizontally between rails 15, 16 from right to left, Fig. 1, a micro-switch 17 being operated twice by respective cards to drive a sprocket 20 to move a chain 21 having card pushers 23 a distance 2x. The leading card 11 operates a micro-switch 27 to drive a tractor (28), Fig. 2 (not shown) provided with pins 14 to move a continuous sheet 12 of mailer cards 13 upwardly. As sheet 12 moves up, a micro-switch 45 senses an aperture 31 and raises lifters 41 via a shaft (46), Fig. 2 (not shown), an eccentric (47), a link (48), a shaft 49, gears (50) and racks 51. Lifters 41 move the two cards 11 to be mounted upwardly at the same rate as sheet 12 to positions adjacent card 13 (shown dotted in Fig. 1).
