Title: Improvements relating to the production of welded tubes
IPC: B23K11/06
Filed: 1958-07-25
Abstract: 881,957. Making tubes; welding by pressure. MORSBACH, P. July 25, 1958 [July 25, 1957], No. 23978/58. Classes 83 (2) and 83 (4).

Title: Improvements in or relating to windscreen wiper mechanisms
IPC: B60S1/48
Filed: 1958-07-25
Abstract: 861,028. Control of D.C. motors. GENERAL MOTORS CORPORATION. July 25, 1958 [July 26, 1957], No. 23991/58. Class 38 (3). [Also in Group XXIII] A control system for the electric motor of a combined windscreen washer and wiper operates as follows. When bridging member 211 is moved to the low or high-speed position, electromagnet coil 107 is energized through bridging member 211, contact 214, wires 205, 204, 193, coil 107, wire 190, 188 and 187 and to the battery. This causes the movement of armature 110 and the closure of contacts 122 and 124 which energize the motor from the battery through the thermal overload switch 186, wires 187 and 188, contacts 122 and 124, wire 191, series field winding 192 and armature 70. Shunt field-winding 194 will also be energized directly to earth in the low-speed position or through resistor 215 to earth in a high-speed position. Co-ordinated operation of the windscreen washer and wiper unit occurs when the bridging contact 210 is closed momentarily, energizing electromagnet 106 and washer unit electromagnet 163, energization of coil 107 being from the battery through overload switch 186, wires 187, 188 and 190, the coil 107, wires 193, 204, 205, and switch contacts 209 and 210. The washer electromagnet coil 166a is energized from the battery through wires 187, 189, coil 166a and wire 207 and switch contacts 208 and 210. Energization of the wiper electromagnet actuates armature 110 as previously described, and the energization of electromagnet 163 permits the driving pawl 149a to engage a tooth on ratchet cam 154. Bridging contact 210 can now be opened since the wiper electromagnet is now energized from the battery through contacts 174, 176. Similarly, tang 169 of armature ramp 165 engages cam surface 158 so that the washer electromagnet 163 does not have to be de-energized. The movement of ratchet cam 154 through the distance of one tooth and the engagement of follower 177 with cam 159, followed by the separation of contacts 173 and 175 causes deenergization of shunt field-winding 194 and thus motor 66 operates at high speed. After 180 degrees of rotation these contacts engage and motor 66 operates at the low speed, while simultaneously the drive to pump rod 135 is discontinued. When the ratchet cam arrives at a starting position, follower 178 engages cam 160 to separate contacts 174, 176, thereby de-energizing the wiper unit electromagnet 106, and the wiper blades will automatically move to the parked position as previously described. If the washer unit is actuated while the wipers are working the motor 66 will automatically operate at high speed during the washing cycle and at low speed during the drying cycle after which it will return to its original manual speed setting. Specification 820,776 is referred to.

Title: Improvements in the production of composite metallic strip
IPC: C23C2/02
Filed: 1947-09-03
Abstract: 626,826. Coating metals. GLACIER METAL CO., Ltd., and LEATHERS, A. Sept. 3, 1947, No. 24302. [Class 82(ii)] [Also in Group XXII] A process for making composite metal strip comprises feeding a strip of backing metal continuously or intermittently into a bath of molten coating metal from above the level of the melt in the bath, submerging the strip in the molten metal and feeding the strip out from the bath horizontally at a depth below the surface of the molten metal equal to the desired coating thickness, marginal overflow being prevented by side guides, maintaining a constant level of molten metal in the bath, and chilling the strip to freeze the coating layer before the strip emerges from the side guides. Chilling is preferably hastened artificially. A strip 1 of backing metal is fed from a coil 2 through levelling rolls 5, over a roll 8 by means of which a repellent 6 is applied to the underside of the strip, beneath a roll 9 by means of which flux is applied to the top of the strip and into a bath 13 of white metal heated by burners 16. The strip passes under a roller 18 in the bath and leaves the bath over a bar 19 and along a channel formed by side guides 20 where it is cooled by water from sprays 25. The guides 20 may have overhanging flanges spring-presssed downwardly on the strip. The strip then passes to a coiler 24: additionally or alternatively, pulling rolls may be provided. The bath has a sloping bottom so that the temperature is greater at the feeding end than at the delivery end. The repellant may be liquid, paste or powder, and may be applied by pad instead of roller: suitable repellants are tar emulsion, sodium, silicate, oil and wax. The flux may be liquid, paste or powder and may be applied by pad or dusting mechanism; or it may be gaseous, e.g. hydrochloric acid gas, in which case the upper surface of the strip is moistened. The appplication of flux and repellant may take place at any stage between coil and bath. The strip may be pre-heated. Specification 440,258, [Group XXII], is referred to.
