Title: Process for making aqueous electrodepositable polymer compositions
IPC: C25D13/06
Filed: 1971-04-19
Abstract: 1354531 Aqueous polymer compositions; ethylene-maleic anhydride copolymer salts GENERAL ELECTRIC CO 19 April 1971 [12 March 1970] 21240/71 Headings C3R and C3P [Also in Division C7B An aqueous electrocoating polymer composition is made by a process comprising the steps of (a) reacting a polymer having recurrent carboxyl groups and being selected from (1) polyimide prepolymers, (2) polyesters, (3) polyesterimides, and (4) ethylene-maleic anhydride polymers with a nitrogen-containing base to form a water-soluble carboxylate salt of the polymer; (b) either before, during or after the treatment with said base adding sufficient water to the system to dissolve said salt formed in step (a); and (c) adding an acid to the aqueous mixture obtained as a result of steps (a) and (b) to adjust the pH thereof so as to precipitate part of the polymer, whereby a dispersion phase (i.e. containing suspended polymer particles) and a solution phase of the polymer are formed. The acid of step (c) must have the effect of controlling the ratio of fixed (COOH + COO<SP>-</SP>) of the polymer to nitrogen-containing base but must not create cleavage of the polymer. Suitable acids are acetic, formic, butyric, propionic and benzoic acids. By adjusting the pH, the ratio of solution phase to dispersion phase is adjusted and this controls how thick a film can be electrodeposited on a metal substrate anode. The pH may be adjusted to 3À0 to 6À5. Electrodeposition may be on to a Cu wire, e.g. using a degreased, acid-cleaned, water-rinsed Cu wire anode immersed in the electrocoating composition together with carbon cathodes, the composition being stirred by a magnetic stirring bar. Deposited resins may be thermally cured. The above-specified polymers 1 to 4 are of the same kinds as, and are made similarly to, those disclosed in Specification 1,354,532 (see the abridgment of that Specification). Polyimide prepolymers are referred to therein as polyamic acids.

Title: Improvements in or relating to masts and the like
IPC: E04H12/20
Filed: 1942-06-22
Abstract: 560,858. Masts. CONSTRUCTORS, Ltd., SCRIVENER, W. C., and BREWER, A. G. June 22, 1942, No. 21405/43. Divided out of 560,841. [Class 20 (i)] A mast is formed of non-telescopic rigid superposed tubular members which are connected together by means which prevent any substantial relative movement between the members in a longitudinal direction. In one form the ends of the members 4, 5 to be joined are provided with slotted plates 7 having upstanding plugs 9 which fit the ends of the members and these slotted plates are brought close together with a plate 10 between them. This plate is provided with double-lipped projections 11 to which the ends of guy ropes 5a may be hooked, the lips of the projections passing through the aligned slots 8 in the plates 7 as they are brought together, so that on rotation of the members, the plates 7 are loosely locked in contact with the plate 10 and are thus prevented from accidental disengagement. A stop pin 13 prevents relative rotation of the members for unlocking. In a modification, Fig. 3, the intervening plate 45 is also slotted so that the slots therein may register with the slots in the end plates of the members 4, 5 to allow passage for the loose lipped-members 46 attached to the ends of the guy ropes. Relative rotation between the ends of the members and the intervening plate causes loose locking of the joint. Specifications 560,851 and 560,853 are referred to.

Title: Improvements in the manufacture of pitch coke
IPC: C10B55/02
Filed: 1937-08-03
Abstract: 499,669. Materials for making coke. VETROCOKE. Aug. 3, 1937, No. 21444. Convention date, Aug. 4, 1936. [Class 55 (ii)] In the production of coke by coking mixtures of coal tar pitch and graphite in externally heated coke-ovens, the graphite is obtained directly from the distillation gases produced, by cracking the heavy hydrocarbons therein in high temperature heating chambers at a temperature between 800 and 1400‹ C. The gases obtained from coking the mixed materials in retorts a flow to a common collector g and from thence to a separating chamber i and a cooling chamber l to offtake m. Cracking takes place in the chamber i by introducing therein through nozzles o, preheated air for combustion with the gases in situ or the burnt gases obtained by the combustion of part of the offtake gases with air. The bulk of the graphite separates in chamber i and some in chamber l. The combustion products from the heating flues c of the ovens may be used for preheating the air supplied to the cracking chamber. The latter is cooled prior to discharging the graphite.

Title: Improvements in conveyors
IPC: B65G19/14
Filed: 1949-08-23
Abstract: 659,471. Conveyers. HAPMAN, H. W. Aug. 23, 1949, No. 21852. [Class 78 (i)] A conveyer structure comprises a circuitous conveyer conduit having at least one abrupt bend, a flight conveyer movably mounted in the conduit and having an endless flexible propelling member with spaced conveyer flights mounted thereon, a housing interposed in the bend of the conveyer conduit, the housing having an inlet in the upper portion thereof and an outlet in the lower portion thereof for the entrance and exit respectively of the flight conveyer, a material slide extending downwardly from the inlet toward the outlet, and upper and lower guide wheels journalled one below the other in the housing and positioned to guide the flight conveyer in a sinuous path away from the material pathway down the slide between the inlet and outlet, the lower guide wheel being positioned near the lower portion of the slide for directing the flight conveyer into close proximity to the slide whereby to again pick up the conveyed material which has slid down the slide after the material freed conveyer has passed around the guide wheels and convey the regained material outward from the housing through the outlet. As shown in Fig. 1, the material is conveyed in a closed conduit and is discharged through apertures 5a to hoppers 5b into a series of hoppers 19, 20 and 21 connected by shoots to the conduit 6. At the upper bends houses 11 and 12 enclose guides for the conveyer. As shown in Fig. 2, the material passes up conduit 33 connected to conduit 7 and into a housing 11 and falls down a shoot 39 into conduit 37 connected to conduit 5 while the conveyer passes round a sprocket and idle pulley in the housing. The housing has side, end and top members 30, 31 and 32. The upper sprocket is adjustable by means of members 53 by nuts 55 engaging therewith. The members 53 engage slide members 43 secured to the side member 30 and having slots 40 so that the sprocket mounted on a shaft 41 in bearings 42 in the side members can be adjusted vertically. A similar arrangement in housing 12, Fig. 5, has the upper sprocket 93 driven by a belt 101 from a motor 97 and the material entering by conduit 95 flows to the conduit 102, whereas the conveyer passes round guide sprocket 93 and pulley 105. A further arrangement is shown in Fig. 9 in which the conveyer passes round sprockets 159, 173 and split pulley 152 and the material flows from a loading hopper 120 to a discharge vat 124. The conveyer chain comprises interconnected links 22 having lugs 24 to which are bolted the disc flights 25 between flight supporting plates 26. An aperture in the flights provides for passage round the sprocket. Various alternative forms of conveyer flights and pulleys are described in which flights may be connected to lugs, one attached to each side of a link or a single rectangular flight may be connected to lugs and frictionally engage the surface of a drum pulley. Alternatively a grooved pulley may be used with a circular disc flight.

Filed: 1969-04-30
Abstract: 1,236,672. Programmed control of machine tools. INTERNATIONAL BUSINESS MACHINES CORP. April 30, 1969 [May 13, 1968], No.21914/69. Heading G3N. A machine tool control system includes a computer generating command words which are held in a data store and singly transferred to an output register either once or a plurality of times. As shown, a cutter location tape is read by a post-processor 2 which converts the information on to cards, or magnetic tape, which are fed to input/ output devices 4 of a computer 1. The electrical signals from the devices 4 are fed to central processing unit 6 associated with a core store 27. The contents of the core store is interrogated by a channel 10, 11 for each machine which contains an output register into which is brought the contents of a selected area of the core store. Channel 10 is connected through a transmission control 14 to receive control unit 14 for a machine tool 22. Each programmed command word stored in the core store 27 is calculated for a set resolution of machine travel and ratio m of set resolution to actual machine resolution is programmed in the command word and set into a pre-set counter 36 through the transmission control unit 14. The receive control unit incorporates a pulse oscillator, an output of which is fed to the pre-set counter 36 to derive a pulse train on line 38 which gates m repetitive command words to the receive control unit for every word read by the channel 10 from the core store and held in the output register. When the travel is within the set resolution the ratio m is programmed as unity whereby each command word is read once and the machine tool effects a single actual resolution of travel. It is stated that the ratio m can be directly set in the counter 36 and the output register located in the receive control unit whereby the data transmission rate is reduced so alleviating noise and bandwidth problems where the computer is remote from the machine tool.

Title: Improvements in or relating to suction cleaners
IPC: A47L9/10
Filed: 1944-11-08
Abstract: 580,914. Suction cleaner filters. HOOVER, Ltd. Nov. 8, 1944, Nos, 21957 and 21958. Convention dates, Nov. 11, 1943. [Classes 8 (i) and 8 (ii)] In a suction cleaner comprising a casing having an initial dirt separator 19, a filter 33 and a relatively movable filter-cleaning nozzle 46, the latter is driven by a periodically loaded energystoring unit, e.g., a spring motor. Power from a coiled spring 71, the inner end of which is connected to a sleeve 72 rotatably mounted on a' fixed shaft 69, is transmitted through a train of gears 76, 77, 82 to a shaft 83 carrying a pinion 86 meshing with a toothed wheel 48 secured to a hollow arm 47 of the nozzle 46. The spring is loaded by five strokes of a pedal lever 91 rotatably mounted on a shaft 92 carrying a bevel pinion 102 meshing with pinion 103 on the sleeve 72. The spring becomes unwound and so rotates the nozzle on releasing lever 91 when a spring-pressed detent 104 on the lever 91 normally engaging a ratchet 106 keyed to the shaft engages a fixed shoulder on its support. Suction from the initial separator exhausted by means of a fan is applied to the rotating nozzle by closing an inlet port valve 56 controlled by a solenoid energised by the closing of a switch 66 by a cam 101 carried by the shaft 92. Nozzle rotation speed is checked by a paddle wheel governor 111 geared to the transmission shaft 83. In a modification, Fig. 8, the spring is automatically loaded and the nozzle started by the collapse of spring-expanded bellows 183 by high suction at the inlet 38 occasioned by momentary increased sealing contact between the main cleaning nozzle and the carpet, the inlet being connected to the bellows by a conduit 184. The spring attached to a shaft 166 is loaded by the counterclockwise movement of a pawl 192 mounted on a pin 190, in turn mounted on an arm 188 secured to the bellows face 186 and carried by a rocker arm 189, and which movement is transmitted from a rachet wheel 194 through a train of gears, 198, 167. A pawl 181 engages a rachet 169 to prevent the clockwise movement of the shaft 166 being transmitted to the nozzle 46a. To start rotation of the filter-cleaning nozzle the forward end of a detent 201, normally engaging the rachet 194, is released when a pin on the gear wheel 167 engages a lever 207 to trip the pawl 192. The detent 201 actuates a switch to energise a solenoid controlling a valve in to inlet 38 to provide suction to the filter-cleaning nozzle.

Title: Process for the filtration of viscose solutions
IPC: D21D5/02
Filed: 1964-05-27
Abstract: Liquid, e.g. synthetic film-spinning material, is introduced at 2 in the figure (not shown), to a vessel where it is mixed with granules of polyvinyl chloride introduced from a dosing device 3. The mixture is pumped (4) to a filter 1 furnished with horizontal filter elements each provided at the top only with metal fabric and covered already with a mixture of P.V.C. granules and viscose. When the pressure difference is excessive, filtration is interrupted and the contents of the filter passed back to the container for the liquid (not shown).  The filter cake on the elements is freed from viscose by compressed air introduced at 5 and is then washed with water from pipe 6.  Next, the elements are rotated by motor 7 to throw off the cake and suspend it in a little water, the resulting suspension being fed to an agitator 8 where soda lye is introduced from a container 9 and heating is effected by introducing steam.  The suspension is agitated and pumped (10) to the inside of a screen 12 rotating partly submerged in water in a conical vessel 11.  Here, impurities float off into a funnel 14, while the P.V.C. granules sink through the screen, and are dehydrated in a suction strainer or centrifuge 13 for return to the dosing device 3.  Instead of P.V.C. there may be used polyethylene, polypropylene, polyacrylonitrile, metal powder or metal chips.

Title: Improvements in or relating to focussing and view finding mechanism for photographiccameras
IPC: G03B13/20
Filed: 1935-08-02
Abstract: 457,351. Photographic cameras combined with telemeters. POLYFOTO, Ltd., 141, New Bond Street, and WATSON & SONS, Ltd., W., 313, High Holborn, both in London, and GREEN, C. E., 68, The Drive, Barnet, Hertfordshire. Aug. 2, 1935, No. 21973. [Classes 97 (i) and 98 (i)] In a combined telemeter and viewfinder in which the telemeter field is so dimensioned that it serves for view-finding, the telemeter and objective focusing mechanisms are linked so that as the telemeter adjustment is made, the objective is automatically focused, and correction is made for parallax between the finder and objective fields. As shown, the telemeter comprises a fixed prism 3, Fig. 1, with a halfsilvered reflecting surface, and a prism 6 rotatable for the coincidence adjustment. The telemeter images, which serve also for view-finding, are viewed through an eyepiece 2 carried by a saddle straddling the prism 3 and pivoted to the camera casing on an axis passing centrally through the prism 3. The pivots are extended above and below at 5 ; to the lower extension is clamped a rod 7 carrying an adjustable clip 13 through which is slidable a rod 8 clamped to the rotatable mount of the adjustable prism 6 ; and to the upper extension is clamped a rod 26 actuated from the camera focus-adjusting mechanism in order to rotate the eyepiece 2 to correct for parallax, this rotation serving simultaneously through the linkage 7, 8 to adjust the prism 6 for coincidence. The objective is focused by turning a knob 14 on a shaft 29 driving through gearing 15, 15<1>, 30, 16 a pair of rings 17, 18, Fig. 3, mounted separately on tubular shafts 19, 20. In shaft 19 is a cam groove 21 engaging a pin 23 on a fixed tubular shaft 31. The mount 32 of the objective 25 is fixed to shaft 19, and is thus caused by the pin and groove to. move axially for focusing. In shaft 20 is a cam-groove 22 engaging a pin 24 prevented from turning about the common axis of the shafts by a slot 28 in a fixed tube 33 ; to pin 24 is fixed a clip 34 in which slides the end of the rod 26, so that as the objective 25 is adjusted for focusing, rod 26 is rocked by the pin and groove to produce the above described actuation of the eyepiece 2 and prism 6. One or both of the telemeter windows may be of coloured glass, and if both are coloured their colourings are preferably complementary. A modification is mentioned in which the viewing tube 2, the prism 3, and the mounting of the prism 6 are rocked as a whole by the control knob and relative adjustment of the prism 6 alone is made by a linkage similar to the levers 7, 8. Specification 412,517 is referred to.
