Title: The coating of surfaces with compositions comprising synthetic resins
IPC: B05D1/02
Filed: 1946-01-02
Abstract: <PICT:0605651/III/1> <PICT:0605651/III/2> Surfaces are coated by spraying a dispersion comprising a thermoplastic synthetic resin and a plasticizer therefor in the direction of the surface, said spray being admixed with a stream of hot gas, whereby gellation of the dispersion takes place before and/or after the spray reaches the surface.  The hot gas may be admixed with the spray by ejecting it from an annular nozzle through the middle of which the spray is passed or by ejecting it from a plurality of nozzles arranged around the spray in such a manner that the jets of hot gas converge on the spray.  The spray may be produced by atomising the dispersion by means of a blast of cold gas which may be inert to the dispersion, e.g. nitrogen or carbon dioxide.  Specified resins are polymers and copolymers of vinyl chloride, vinylacetate, methyl methacrylate, butyl methacrylate, ethylene and styrene, while specified plasticizers are xylene, cyclohexanone, tricresyl phosphate, dibutyl phthalate and dioctylphthalate.  Figs. 1 and 2 show an apparatus which may be used.  The resin is forced by air pressure into outer tube of spray pistol 1, and is atomised by nitrogen blown through centre jet 2.  Hot gas under pressure is blown into annular tube 3 and emerges through the six nozzles 4.  The annular tube is soldered to a metal ring 5, fitting upon asbestos cylinder 6. Control of gas to 2 and 3 is attained by taps not shown.

IPC: B21C37/20
Filed: 1958-01-06
Abstract: 852,368. Rolling ribbed tubes. ACCLES & POLLOCK Ltd. Dec. 29, 1958 [Jan. 6, 1958], No. 401/58. Classes 83 (2) and 83 (4). Means for forming a helical fin on a metal tube comprises a plurality of roll units spaced around the tube, each unit including a fin-finishing portion consisting of a plurality of independently rotatable loose discs each with an outer annular portion of wedge-section, adjacent groups of said discs having annular portions of different wedge angle, those annular portions in each group having a larger angle than those of a preceding group considered in the order of their operation and some of the discs in each group being of progressively increasing diameter in their order of operation. A helical fin 1 is formed on a tube 2 by three or four fin-forming rolls spaced equiangularly around the tube, the axes of the rolls being at a slight angle to the tube axis. Each roll comprises a part 3 having parallel-sided annuli 4 for the initial formation of the fin 1 and a series of freely-mounted discs 9 having annular peripheral parts 10. The part 3 may be a single piece or in two pieces clamped between a collar 5 on a shaft 6 and a spacer-ring 7 pressed by a nut 8, the discs 9 being mounted freely on the spacer ring. The part 3 is positively driven and advances the tube while the discs 9 are independently driven by the rotation of the tube. The initial annuli on the part 3 have concave tips, the last three have semicircular tips, while the remainder have square tips. The annuli are equally-pitched on the rolls but are staggered axially from roll to roll by a fraction of the pitch equal to the reciprocal of the number of rolls. The annuli 10 on the discs 9 are arranged in groups a, b, c, the annuli of each group being distributed among the three rolls and each group having wedge-shaped annuli having the same wedge-angle (3¢ degrees, 6 degrees, 7¥ degrees for groups a, b, c, respectively). A particular part of the fin is engaged successively by an annulus of group a) from each roll in turn, the constant angle wedge formation of each annulus acting at a different radial location on the surface of the fin due to the progressively-increasing diameter of the annuli within the group, that part of the annulus which is not wedge-shaped being parallel-sided so that contact with the fin is localized and restricted to the wedge surfaces. When the annuli of the first group have traversed the full depth of the fin, the first annulus of the next group, which annulus has a reduced diameter and an increased wedge angle, engages the same part of the fin and the process is repeated until that particular portion of the fin has been successively traversed by all the annuli on the rolls. Certain of the discs 9 have annuli which are wholly of wedge formation. Specification 845,242 is referred to.

Title: Steam and self discharging apparatus for neutralizing sulphate of ammonia in its wet state
IPC: C01C1/249
Filed: 1922-01-10
Abstract: 188,587. Royston, G. Jan. 10, 1922. Ammonium sulphate.- In apparatus for the neutralization of ammonium sulphate in its wet state, as received direct from the saturator, the salt is circulated through the apparatus with ammonia gas and steam until the neutralization has been effected. The crude salt is introduced from the saturator into the tank a up to the level of the overflow-ripe c, and ammonia gas and steam are drawn in by the injector z and pipe d the end of which is bent to project upwards into the larger pipe w. The wet salt is thus made to travel through the pipes w, x into the tank again, the process being continued until neutralization is complete, which is determined by testing samples drawn from the open-top portion of the tank shut off by the sealing-curtain o. The finished salt may be discharged through the valve j, or alternatively steam alone may be supplied to the injector z and the salt discharged through the valve g. To assist the circulation, the tank is provided with an inverted conical structure i, the surface of which slopes towards the point J. The circulation may also be assisted by the introduction of steam through the pipe q.

Abstract: 1342461 Measuring transmittance photoelectrically SUSQUEHANNA CORP 7 Jan 1972 [22 Jan 1971] 744/72 Addition to 1312838 Heading G1A In a modification of the opacity measuring system of Specification (1312838) noise interference is suppressed by supplying pulse signals to the detecting circuitry 12 in synchronism with the pulsed output from the photocell 40, thereby elevating the level of the photocell output pulses with respect to the noise level. The pulse signals are supplied by an oscillator 24, which also provides the firing pulses for the, light source 22, and are shaped into voltage spikes by components 38, 39. Thus, even at 100% opacity, there is still a small output from amplifier 50 and hence there is a small voltage level on the lower plate of capacitor 50. This level is designed to be greater than the noise voltage level. (For Figure see next page)

Title: Improvements relating to the testing of electrical apparatus
IPC: G01R31/327
Filed: 1951-01-12
Abstract: 707,741. Detecting faults. SLANEY, A. H. April 10, 1952 [Jan. 12, 1951], No. 889/51. Class 37 A test plug, for testing high voltage switchgear which is normally operable by relayoperating pilot means from a remote location, is adapted to be engaged in a socket to which main and pilot lines from the relay-operated switch gear are connected, and has test means for connection to the switch gear and relay-operating pilot means adapted for connection to the pilot lead, and includes a manually operated switch. The invention is shown as applied to the testing of the remote control switch gear and trailing cable used in coal mining machinery. A control panel 1, Figs. 1 and 2 has a socket 2 into which is normally fitted a plug 3 on one end of a trailing cable 4, the far end of which has a similar plug for engagement with' the coal-cutting or other machinery. The cable 4 contains three main lines A, B, C, which connect with three-phase supply lines A1, B1, C1, in the control panel, and a pilot line D through which a pilot relay G is controlled. This controls a working relay H which operates in sequence to actuate the contactor F test plug 9, Fig. 3,.has pins 5, 6, 7 for engaging the main line sockets and a pin 8 for engaging the pilot line socket. For testing the control panel the test plug 9 is inserted in the panel socket in place of the trailing cable 4 as shown in Fig. 1, while for testing the cable 4 the test plug is inserted into a socket in a coupler 10, Fig. 2, which has a second socket into which the plug 3 at the far end of the cable 4 is inserted. The test plug 9 comprises a brass casing 11 which is earthed, and within which are neon lamps 12, 13, 14 connected in star to the main pins 5, 6, 7 and observable through windows in the casing. Connected to the pilot pin 8 are a choke 29 and condenser 30 which are connected to contacts 19, 20 on a hand control switch 16. This comprises a rod 23 slidable and rotatable in a sleeve 24 and having on its outer end a hand grip 25 and on its inner end a contact member 21 having a high part 21a and a low part 21b. Normally the member 21 is out of engagement with both contacts 19, 20. On pushing in the rod 23 the high part 21a engages the contact 20 and connects the choke 29 and condenser 30 between the pin 8 and the earthed casing 11. The switch is then rotated so that the contact 19 is also engaged by the contact member 21. The condenser 30 and choke 29 are thus short-circuited, the pilot relay operates, and the working relay is opened. The switch is then turned back to disengage the contact 19 and cause the working relay contacts to reclose. As the pilot relay contacts are also closed the contactor F is switched on. If there is no fault the lamps 12, 13 14, light up; if any lamp does not light a fault exists in the lead to which it is connected. In a modification a resistance and rectifier are substituted for the condenser and choke.

IPC: F01K7/38
Filed: 1978-12-29
Abstract: PURPOSE: To simplify turbine structure and to improve property by providing a steam passage from a high pressure section to upper part of low pressure section without setting up a flow regulating valve at a low pressure entrance at the back of an exhaust port of high pressure section.  
     CONSTITUTION: An extraction turbine body 1 is constituted without setting up any regulation valve at the entrance of a low pressure stage 5. Extraction pressure P 3  is regulated by adjusting an opening grade of an entrance regulating valve 8 through a regulating lever 14 by a pressure regulator 10. For increasing the low pressure section flow or the output, a setting value of the pressure setter 11 is raised and the  extraction pressure regulatot 10 is moved downward to turn the lever clockwise  arround the fulcrum 15, while the opening grade of the entrance regulating valve is  increased for increasing a steam inflow volume. In this way the steam passage can  be simplified and the output can be improved without setting any regulating valve  at the entrance of the low pressure stage.
