Title: Method and apparatus for heating, melting and hot-spraying thermoplastic materials
IPC: B05B7/16
Filed: 1950-08-29
Abstract: 695,966. Spray-producers. KOPPERSCHMIDT, W. Aug. 29, 1950 [Sept. 1, 1949], No. 21352/50. Class 69(iii) Thermoplastic or like materials 24, which are solid or paste-like at normal temperatures. are placed on a pipe coil or grating 23 within a closed vessel 1, which is enclosed within heat-insulated material, and heated by electric elements 27 or by steam or hot oil pipes. The coil 23 may be heated by oil, steam, or electrically, and the melted material passes through a screen 3 to a second heating receptacle 4 containing a filter screen 5. A circulating pump 7 feeds the material through passages 6, 8 to a heated pipe coil 9, and then to a spray device, not shown, via a valve 11. By closing the valve 11 and opening a valve 15 the material may be directed through a passage 14 to nozzles 13, from which the molten material is directed on to the cold material 24. Alternatively, by the operation of valves, the nozzles 13 may be fed with hot material by the return line 18 of a spray device, not shown. One or more further heating chambers 29 are provided with heating means 30 such as electric elements, steam coils, or coils for hot gases or liquids. One such chamber, with the aid of a circulating pump 79, supplies heating fluid to the coil 23 and to spraying devices, and another chamber heats a gas which is fed to the spraying devices, not shown. Cleaning fluid reservoirs 36, 37, and a pressure vessel 38, arranged adjacent the main heater serve, together with the pump 7, to feed cleaning fluid through the vessels, pipes &c. after spraying. Compressed air is fed to the vessel 38 through a line 49 and a valve 50. The vessel 1 may be brought under pressure by pressure air or gas admitted via a threeway valve 52 and a one-way valve 56. Hot spray material is fed to spray devices through concentric hose lines, one of the passages thereof containing hot gas or oil &c., or alternatively, a return flow of spray material back to the heater. A proportion of the gases fed to the sprayers may assist in the spraying, or form a protective gaseous jacket around the sprayed jet. Gas not used to assist spraying is circulated back to the heater. For close temperature control of the spraying material, thermostatically controlled electric heating elements may surround the hoses. In one embodiment. Fig. 2, spray material is fed through a hose line 65 to the sprayer 12, and a spray material return line 66 surrounds it. Hot gas is fed to a coupling 63 and assists the spraying operation.
Patent GB-213606-A (GB)
Abstract: 213,606. Krupp Akt.-Ges., F. March 31, 1933, [Convention date]. Controllers; electric braking. - Relates to motor operating mechanism for circulating machines, cash registers, &c. in which at the end of an operation of the machine the coupling between the driving motor and the main shaft is released, the shaft locked, and the motor circuit interrupted and consists in the provision of a switch whereby after the armature of the motor is disconnected from the main conductor it is connected up in the reverse direction to its exciting winding to facilitate the stopping of the motor and prevent unnecessary stresses. The main shaft A of the machine carries a worm wheel a<1> loosely mounted thereon and a disc a<2> fixed thereto which form the two elements of a known kind of clutch mechanism. The disc a<2> has a lug a<3> adapted to co-operate with a bent lug b<1> on a pivoted locking lever B con- - trolled by a spring b<3> and thrust bar b<4>. The end of the lever B has a surface b<7> which in the position of rest, Fig. 1, abuts against a lug c<1> of a locking disc C secured to the shaft A and provided with a pin c<4> working in a slot c<5> in another disc c<2> controlled by a spring c<3> and limited as to its rotation by the length of the slot c<5>. In this position a lug c<6> on the disc c<2> abuts against the lug b<1> of the locking lever and a notch on each disc is presented to a roller d<1> mounted on a pivoted bell crank lever D which has a projection d<3> adapted to co-operate with the lug c<1> of the disc C and has the free end of its arm d<4> in contact with an insulating bar e<5> on the arms of a double-pole doublethrow switch E<1>, E<2>. The arms E<1>, E<2> are connected as shown in Fig. 7, to the exciting winding F of the motor and engage, in the position of rest or in the operative position respectively, with contacts e<6>, e<7> or e<3>, e<4>. The contact e<3> is connected to the starting resistances H and the positive main conductor, the contacts e<4>, e<6> are connected together, and the contact e<7> leads to the negative main conductor. When the operation is initiated by the. depression of a starting key the locking lever B is rocked to release the discs a<2>, c and c<2>; the disc c<2> is thereby caused to rotate under the action of the spring c<3> and to effect the rocking of the bell crank lever D whereby the switch arms E<1>, E<2> are pressed into engagement with the contacts e<3>, e<4> to complete the motor circuit. The disc a<2> being free to rotate with the worm wheel a<1> effects the rotation of the shaft A and thereby the disc C which is caused to maintain the switch in the operative position. Near the end of the operation the locking lever B is returned bv the bar b<4> to uncouple the worm wheel and stop the shaft A through the engagement of the surface b<7> of the lever with the lug on the dise C. The roller d<1>, however, is not permitted to enter the notches in the discs until the nose d<3> of the lever is freed from the lug c<1> so as to prevent the formation of sparks and to ensure a quick reversal of the contacts and thus of the connection to the exciting winding.

[Class 100 (i).] Registering webs longitudinally.-In a high speed rotary printing-machine having an inset-web registering-apparatus as described in the parent Specification, the contact devices associated with the inset-web conveyer comprise at least two contacts travelling at the speed of the inset web and movable radially or substantially radially of the conveyer to engage the co-operating contact on the opposite side of the web when the web is out of register. As shown, two groups of pins 9, 10 are mounted in a box 3 of insulating material secured in a gap in the conveyer cylinder 1 over which the inset web 17 passes. The inner ends of the pins are slidably mounted in metal plates 11, 12 connected by leads 15, 16 to the circuits operating the feed-correcting devices. Springs 14 bearing against collars 13 on the pins tend to press the pins radially outward. When the web is in register the perforations in it engage the central portion of the box 3, but if it creeps or lags, a perforation coincides with one of the pins 9 or 10, allowing it to move outwards into contact with the co-operating contact 18 and initiate the correcting operation. This contact 18 may be a flexible metal ribbon secured at its ends to a pair of arms 20, 21 pivoted to a member 24 radially movable to cause the ribbon to embrace the cylinder 1 closely. Instead of a flexible ribbon a rigid curved contact phase may be used. In a modification, the device carrying the contact pins may be mounted externally of the cylinder 1 on an endless belt or chain so arranged that the pins move for a predetermined period adjacent to and at the speed of the conveyer. In this case the conveyer carries two plain contact strips. The springs 14 may be omitted, the pins being projected by centrifugal force, or the external contact may be magnetic. Instead of pins 9, 10, spiral springs may be used.
