Title: Method of and apparatus for electrostatic spray painting
IPC: B05B5/057
Filed: 1956-07-17
Abstract: In a method of electrostatic spray-painting, the workpiece is connected to one side of a source of high voltage and a plate-like spray head to the other, paint being supplied to the upper surface of the spray head so that it flows by gravity to an edge thereof at which it is atomized and charged so as to be deposited on the workpiece.  As shown in Fig. 1, the spray <PICT:0793596/III/1> <PICT:0793596/III/2> head comprises a metal plate 20, bent as shown and supported on an insulator 28.  Paint is slowly fed through a tube 30 from a pressurized or elevated supply tank 34 to the sloping surface 32 of the plate 20, whence it flows down to the end 24 which is preferably rounded at the top edge, and provided with a knife edge below, at which the paint is atomized; a groove may be provided adjacent to the spraying edge.  The spray head is connected to the negative pole of a high voltage D.C. source, the positive pole of which is earthed.  The workpiece 36 is carried through the field of spray on an earthed conveyer, and its movement may be used for operating switches 52, 54 controlling the current to the head 20; relays may be used to hold the circuits open or closed for predetermined times after the operation of the switches, and control valves may be fitted to the paint conduit.  As shown in Fig. 4 the spray head may also consist of a flat tapered plate 20 of non-metallic material such as a synthetic resin, e.g. polystyrene, or hard rubber or the like, mounted on a metal stud 40 which is pivoted to a metal stand 48, connected to the negative terminal of the power supply.  The paint is delivered by a tube 30, preferably non-metallic.  Paints which react with the surface to be coated, or two or more materials which react with each other during the spraying operation, may be sprayed.  The article to be coated may be pre-heated, e.g. when it is non-conductive, such as a steel steering wheel having a rubber-like covering, and shields, which may or may not be connected in circuit, may be used to direct the spray.

Title: Improvements in or relating to the case-harding or cementation of ordinary or chromium steel
IPC: C23C8/22
Filed: 1936-08-11
Abstract: Gas for the cementation of ordinary or chromium steel is produced by removing from producer gas, water gas or a gaseous mixture containing carbon monoxide and hydrogen, substantially all the carbon dioxide and water vapour contained therein by passing the gas over a column of carbon raised to a temperature higher than the cementation temperature, i.e. above 900 DEG  C., and adding to the treated gas a small proportion not exceeding 12 per cent of a saturated aliphatic hydrocarbon.  The column of carbon may be heated to the desired temperature by an electric heating device employing rings of silicon carbide or a resistance of an iron-chromium aluminium alloy.  In an example the gas used contains 30-50 per cent of carbon monoxide, 10-50 of hydrogen, the rest nitrogen and either 3-12 per cent of methane and ethane or 1-6 of butane and propane.

[Also in Group XIII] In apparatus for the continuous drying of material of varying suspension capacity, such as wood waste, in an ascending gas current [Group XIII] the material being supplied in countercurrent, hot gas is drawn through a screen 8 by the action of a fan 1 and the wet material, fed centrally into the chamber 4 through a bucket wheel 46, is distributed by a slowly rotating stirrer 10 having vanes 11 and consisting of four arms 18 fixed on a hollow shaft 19 through which cool air passes to cool the bearings 20, 21. Lighter dried material is carried in suspension into separator 23 while coarse material remaining on the screen is ejected by the stirrer through lateral openings 14 into a container 17. In a modification the coarse material is sorted into different secondary containers. In another modification a discharge lock for the coarse material, the feed lock of the wet material and the stirrer mechanism are driven from a common source or the shaft 19 also drives a feed screw conveyer. In a further modification the gas discharged from the drier is supplied via a separator to preliminary driers from which the coarse material remaining is fed into the final drier. In a still further modification, Fig. 6, moist material is fed through lock 71 into drying chamber 72, gas heated by heat exchanger 85 being supplied thereto and the coarse material being ejected by stirrer 76 through opening 77 and pipe 78 into final drier 79 which is supplied with gas heated by heat exchanger 86. The stirrers 76, 83 have a common shaft and the dried coarse material is discharged through lock 84. In Fig. 8 the discharged drying gas from a drying chamber 104 is drawn by a fan 105 into a separator 106, and then passes through a vibrating sieve 107 on which moist material is initially heated before passing to the drier.

The lever is locked in position by the engagement of a spring-biased detent 42, which passes through the lever, with a pair of toothed segments provided at the ends of the transmission levers 39 fixed to the shaft on either side of the supporting lever. The shape of the detent and toothed segments allow the seat support to be gradually raised. However, if it is desired to lower the seat support, the support must first be raised to the upper end position in which the detent completely disengages the toothed segments and then lowered to the lower end position. The detent is prevented from engaging the segments during movement from the upper to the lower end position by a pair of plates 50. Specification No. 1491291 is referred to.

Abstract: 1,114,792. Signalling over power circuits. LANDIS & GYR A.G. 19 May, 1966 [24 May, 1965], No. 22376/66. Heading H4R. In a system for signalling over power circuits the transmitter comprises a source of A.C. at a frequency locked to that of the power system and each receiver includes a frequency-selective circuit tuned to the appropriate transmitter frequency in which the frequency selection at the receiver utilizes correlation techniques. Fig. 1 shows a receiver 8, in which signals on the line are fed through a band-pass filter 11 to a multiplier 12 fed also with the output of an oscillator 13 which is of the same frequency as the signal frequency from the transmitter 7 and which is locked to the power supply frequency in the same way as the transmitter. The product is fed from multiplier 12 to integrator 14 which produces a finite signal to operate relay 15 after a predetermined period if the received signal is a genuine signal. If the phase of the signal received over the line may be subject to random phase variation then two correlation circuits may be used each fed with the received signal and the reference signal one correlator having a 90 degrees phase shift on one input, and the outputs of the correlators being combined, Fig. 2 (not shown). Alternatively the reference oscillator may be dispensed with by using auto correlation and correlating the received signal with a delayed version of the received signal, Fig. 3 (not shown). The correlator may take the form of a Ferraris meter driven by the two signals to be correlated with the inertial mass of the rotor being used as the integrator.

Abstract: 844,475. Nuclear reactors. SIEMENSSCHUCKERTWERK A. G. July 11, 1958 [July 17, 1957], No. 22387/58. Class 39(4). In a heterogeneous nuclear reactor using the same liquid as collant and moderator, the flow of liquid is divided after passing through a heat exchanger 1 and before returning to the reactor. Part of the flow is used to cool the reactor, part passes via a cooling device 5 to a moderator space 3 in the reactor. The moderator flow may after use return to the heat exchanger, or it may be added to the main coolant flow before passing over the fuel 9, Fig. 2. Fig. 5 shows one form of coolant tube used in the second method, coolant entering at the end and moderator at the apertures 14; by throttling the coolant flow this eliminates the moderator pump 13. The innermost tubes may be supplied with moderator only. A by-pass in parallel with the cooling device 5 enables the moderator temperature to be varied for fine reactor control ; the rate of flow of moderator may also vary.

Abstract: 1,129,338. Hydro - pneumatic oscillation dampers. FICHTEL & SACHS A.G. 20 May, 1966 [26 May, 1965], No. 22456/66. Heading F2S. In a single-tube hydropneumatic oscillation damper in which a piston 20 with a rod 16 and damping bores 22 works in a cylinder 10 and a cup-shaped free piston 24, closed toward the piston-rod end, divides the cylinder into a damping chamber 30 and a compensating chamber 32, the compensating chamber contains a gas cushion 38 and sufficient liquid so that, with the damper in a vertical position and the rod 16 uppermost and fully retracted the face between the free piston 24 and the cylinder lies at least partially below the liquid level 34 set inside the piston 24. This ensures that there is always a liquid seal between the damping and compensating chambers. The liquid can also be sufficient so that, with the damper turned through 180 degrees, the liquid level inside the compensating chamber lies above the upper end of the free piston 24. The latter has a seal 28. In a modification, Fig. 3 (not shown), the open end of the free piston is closed by a plate (150) having damping orifices which are controlled by one-way valves (152- 154).

Abstract: 460,723. Adapting electric fires to open fireplaces. FEARNHEAD, J. H. Aug. 9, 1935, No. 22474. [Class 126] A portable self-contained electric firescreen comprising a screen with one or more heating elements incorporated with or fixed to it, is made adjustable in height or width, or both, so that it may fill fireplace openings of different sizes and appear to form part of the interior. The form shown in Figs. 2 and 4 is adjustable in height only, for which purpose the feet C, C<1> supporting the screen B are formed on slotted metal slides D, D<1> adjustably secured by wing- nuts to the screen, which may thus be raised until its top edge coincides with the top of the fireplace opening. A plate B<2> secured to the slides D closes the gap beneath the lower edge of the screen B. The fire may be used in an inclined position by relative adjustment of the front and rear feet C, C<1>. In the construction shown in Fig. 7 the top portion only of the screen is adjustable, and consists of a separate U-section strip E<1> held in position by wing-nuts on studs passing through vertical slots in its rear side, or alternatively by forming it of springy material so that it clips on the screen. Fig. 8 shows a screen having similar adjustable side strips for varying its width and a verticallyadjustable top strip formed in two telescoping parts E<2>, E<3>. Fig. 14 shows a screen with top and side adjusting strips G, G<1> hinged to it, the corners being filled up by flaps g hinged to the ends of the strips.

Filed: 1965-05-27
Abstract: 1,083,525. Projectile fuzes. INDUSTRIAL HOLDING ESTABLISHMENT. May 27, 1965 [May 27, 1964], No. 22565/65. Heading F3A. A clockwork projectile fuze functioning on impact in which arming is controlled by a balance wheel 15 has manually adjustable means which can be selectively moved according to the delay in arming required from a locking position to positions in which springs 36, 40 respectively are aligned with a rack 16 connected through a gear train to an escapement wheel 24 which meshes with the balance wheel 15, the springs being of different driving strengths. Before launching the projectile, rack 15 occupies the position shown in Fig. 1, a blind hole 43 being aligned with the firing pin 11, which is supported by a spring 10 and attached to a piston 9 slidable in the fuze cap 2. The adjusting set-screw 5 extends between the ends of a split ring 3, so that as the screw is turned the ring expands to the position of Fig. 1 and locks the cap 2 to the fuze body 1 in the axial direction. On rotation of the cap 2 relative to the body 1, a finger 29 depending from the cap rotates the housing 18 of the arming mechanism within the body 1, so that rack 16 is brought into alignment with spring 36 or 40 as the case may be. Angular movement of the cap is limited by a stop 31 co-operating with the ends of split ring 3. When the projectile is launched, a hollow pin 50 locking the balance wheel 15 sets back due to inertia until its reduced neck portion frees the balance wheel. The pin 50 is locked in the rearward position by a spring 54, which moves into a groove 60. Rearward movement of the pin 50 cannot take place until the fuze is set, when enlarged ends of a slot 55 are brought into alignment with the pin head 56. On unlocking of the balance wheel 15, rack 16 driven by spring 36 (or 40) moves until its detonator 44 is aligned with firing pin 11 and chambers 45, 46. The fuze is then armed for firing on impact. If on impact, piston 9 is not driven in, as with a glancing blow or fall on water, housing 18 moves forwards due to its inertia and brings the detonator 44 against the firing pin.
