Title: Method of producing printed circuit boards
Inventor: KERKHOF HORST
IPC: H05K3/00
Filed: 1963-09-09
Abstract: 1,062,942. Printed circuits. DEUTSCHE GOLD - UND SILBER - SCHEIDEANSTALT. Sept. 9, 1963, No. 35527/63. Heading H1R. In a method of producing printed circuit boards wherein a plurality of wiring patterns are printed in etch-resistant paint on a metalplated board, the unprinted metal is etched away, the board is divided into smaller boards each bearing one wiring pattern, and the patterns are provided with holes where circuit components are to be soldered, at some stage before forming the holes the boards are coated with a protective lacquer which is a true or colloidal aqueous solution. A preferred lacquer contains 86% water, 13.4% polyvinylacetate, and 0.6% pigment, which may be a chromium compound. The lacquer is diluted with water, the proportion of lacquer to water being from 1 : 5 to 1 : 30, preferably 1 : 5 or 1 : 15. In a first example, a metal-clad board is cleaned, treated with lacquer, printed, dried and etched. The printing paint is then washed off and the board is divided into individual boards which are perforated as necessary. Components are positioned on the boards, flux is applied and the boards are dip-soldered. If the paint-removing agent would attack the lacquer, lacquering is deferred until after the paint has been removed. In a second example, solderable printing paint which need not be removed is used.

Title: Improvements in or relating to a method for bending and straightening a cast bar and plant for carrying out such method
IPC: B21D1/02
Filed: 1970-07-23
Abstract: 1,260,450. Straightening. VEREINIGTE OSTERREICHISCHE EISEN - UND STAHLWERKE A.G. 23 July, 1970 [25 July, 1969], No. 35814/70. Headings B3E and B3M. A method for bending and straightening a cast bar 1 comprises feeding the bar through a curved pass of stationary guiding rolls 2, then through a bending and straightening apparatus 3 including an adjustable reaction roll 4 and at least two bending rolls 5, 8, the steps of readjusting one of said bending rolls following said reaction roll when a pressure gauge 28 senses a deviation from a desired value and if said re-adjustment is ineffective, slewing said bending rolls around a horizontal axis in a direction contrary to the re-adjustment to keep said cast bar free from bending moments. The bending and straightening rolls 5, 8 cooperate with pulling rolls 6, 7 the rolls being mounted in insert pieces 10 to 14 in a roll frame 15. Spacers 32, 33 support the insert pieces and maintain equal spacing between the rolls during operation. The rolls 5, 6 and 8 are tightened by hydraulic units 21, 22 and 23. The roll frame is slewable as a unit about a horizontal axis in bearing assemblies 24, 25 and a projection 27 on the delivery side of the frame engages a slewing device 29 through the interposed pressure gauge 28. Adjustable guide pads 31 engage the bar as its enters the rolls. In operation, the roll 5 is adjusted to co-operate with rolls 4 and 8 to remove the curvature R from the cast bar and the bar is passed to a roller table 9. Any bending moment acting on the bar by the rigid guide rolls 2 and from the bar via the rolls upon the roll stand is registered by the gauge 28 and an automatic control at first adjusts the roll 5 to remove the bending moment. If this fails to straighten the bar because the bending moment is in front of the roll 4 the automatic control actuates the slewing device 29 which rotates the roll frame in a direction contrary to that on which the roll 5 has been displaced and the bending moment is removed. The rolls 5, 6, 7 and 8 are designed as shaping rolls to shape the cast bar immediately after its solidification.

Title: Improvements in or relating to devices for the treatment of hanks of yarn, particularly for the dyeing thereof
IPC: D06B3/08
Filed: 1932-12-19
Abstract: <PICT:0408398/IV/1> <PICT:0408398/IV/2> A device for the treatment, particularly dyeing, of hanks, provided with a bar serving as a common support for the yarn carrying members and their driving mechanism, is characterized by means for swining the said supporting bar horizontally, or vertically, or imparting to it a combined or composite movement, and enabling the swinging or other movements to be transmitted to the bar whilst it is located in any position of altitude to which it may be adjusted and also during the operation of so adjusting it.  The mechanism for producing the various movement of the common bar is adapted to be coupled to the mechanism for driving the yarn carrying members.  In Fig. 1, the yarns St, supported on members 61 attached to the wheels 79, are driven by a further set of wheels 78 mounted on the common bar 60.  The wheels 78 are connected by an endless chain 69 which is driven through the wheel 67, bevel wheels 66 and 65, and shaft 64, by the motor 62.  This motor also actuates, through the gear 63, shaft 70, clutch 76, and wheels 71 and 72, the cam roller 73, and a pin 75 engaging the cam slot 74, causes the common bar 60 to be reciprocated horizontally. By means of an independent motor 59, operating through a two-way clutch 56, 57, shaft 55, bevels 54 and screws 51, the common bar 60 may be raised or lowered without interfering with the drive of the yarn carrying members 61.  An alternative method of driving the yarn carrying members, whereby the latter are given an alternating rotary motion (independent of the motion of the common bar 60), is by means of a toothed segment 90 and a crank and crank arm 91 and 92 (Fig. 7).  The Specification as open to inspection under Sect. 91 relates also to improvements in a device according to Specification 378,727, wherein hanks of yarns to be submitted to intermittent dyeing operations are swung to and fro in the bath by means of rods, bars, tubes, rollers, or the like arranged above the bath, characterised by the provision of means which render possible both the interrupted and the uninterrupted drive of the yarn carrying members in all positions which they may occupy, and also during the displacement of said members from one position to another.  It includes also the subject-matter of Specification 408,397, which comprises rotatable yarn carrying members having a star-shaped or cruciform cross-section which can be varied by independent adjustment of one or more of the radius arms.  This subject-matter does not appear in the Specification as accepted.

Title: Drive control means
IPC: F16D65/14
Filed: 1969-07-18
Abstract: 1,267,983. Multi-disc brakes; automatic operation fluid release; shaft couplings. NORTH AMERICAN ROCKWELL CORP. 18 July, 1969 [26 Sept., 1968], No. 36310/69. Headings F2E, F2F and F2U.  A brake has co-operating engageable members respectively on a relatively-stationary support and a shaft connecting a selectively-energizable drive motor to a driven assembly; resilient biasing means acts on a plunger, defining with the support a fluid pressure chamber, in opposition to fluid pressure in the chamber; means are provided to introduce fluid into the chamber only upon energization of the drive motor to disengage the brake and consequently load the bias means; the loaded bias means are effective to displace the plunger to cause braking engagement upon reduction of fluid pressure consequent upon de-energization of the drive motor. In Fig. 4, when a valve 94 is opened to supply hydraulic fluid from reservoir 93 through pump 92 along line 95 to hydraulic motor 73 fluid also passes along line 97 to port 124 and passage 125 to force annular plunger 121 to the right, thereby releasing disc brake 133, 134 and compressing springs 129. Discs 134, which may be rectangular, are supported on pins 128 (e.g. four in number), while discs 133 are splined to a hollow coupling shaft 139 connecting the output shaft 72 of motor 73 with a shaft 142 having splined to it a shaft coupling 146. When valve 94 is closed, pressure in lines 95 and 97 is relieved, whereupon springs 129 immediately apply the brakes. A rigid spacer collar 147 is located between the inner end of shaft 139 and one side of a shoulder 148 on shaft 142. Bearing 143 is retained against the other side of shoulder 148 by spacer collar 149, bearing 144, coupling 146 and nut assembly 151. In Fig. 1, the plunger 59 and springs 88 are orientated the other way round; only three non- rotatable discs 83 are provided, and these are arcuately notched or apertured at 87 to accommodate pins 84 (e.g. six in number). Coupling shaft 71 is in this case externally splined at its inner end 74 to enter the splined hub 75 of a spur gear 15. The output shaft of speed reduction gearing 15, 32, 33, 41 is shown at 35. Fig. 3 (not shown) has the brake assembly and orientation of Fig. 4 with the shaft arrangements (to hub 75 of gear 15) of Fig. 1. The brake discs may have any peripheral configuration and may have frictional material or formations on one or both surfaces. Fewer discs than shown may be used in the Fig. 4 (or Fig. 3) embodiment, in which case housing portion 113 may be retained in the form shown, but an annular spacer of appropriate thickness is interposed between its inner face and the first stationary disc 134 (Figs. 6 and 7, not shown).

Abstract: 1,191,183. Calculating apparatus. H. ADLER. 9 Aug., 1967 [8 Sept., 1966], No. 36569/67. Heading G4B. Apparatus for calculating the estimated time of arrival at a destination or an intermediate check point subsequent to a first check point on the basis of the actual average speed to the first check point comprises a first scale and an expansible scale, extending in parallel relationship to a beam, means for adjusting expansion of the expansible scale, one of the scales carrying time indicia and the other velocity or distance indicia, one of the scales comprising an endless band, means for rotatably supporting the endless band for altering its position and registering means drivingly connected with the rotatable means for recording the rotation of the band. As illustrated the beam 10 carries a distance scale and a velocity scale, and the time scale is provided by an endless extensible band 20, which is mounted at one end in a slidable member 12. The distance between index marks 33, 13 represents 30 minutes. At the start of a journey the actual time, i.e. in minutes, is positioned opposite mark 33 by manipulation of knob 26. The index mark 22 on cursor 21 is set to indicate the distance to a first check point, and the estimated speed is indicated by turning knob 16 until the velocity index mark 13 is appropriately positioned. A ratchet-and-pawl mechanism 27, 29 prevents unwinding of tape 14 from shaft 15. When the first check point is reached the position of the mark 13 is adjusted until the actual time of arrival coincides with the cursor mark 22. The mark 13 then gives true average speed. Rotation of the knob 26 to bring the actual arrival time adjacent the mark 33 will also actuate a revolution counter 28 which indicates the mileage covered. If used at each of a number of intermediate points on a journey the apparatus may include a second counter indicating the distance remaining. In an alternative embodiment the revolution counters are replaced by endless bands, and the apparatus includes a slide (60) (Fig. 3, not shown), the zero of which is aligned with the velocity index mark. When the time scale is readjusted the velocity index mark will indicate on the slide the following or opposing forces, e.g. of wind or water currents.
