Abstract: 1,167,771. Printed circuits. SANDERS ASSOCIATES Inc. 26 April, 1967, No. 19301/67. Heading H1R. Relates particularly to the formation of interconnections or lands between circuit layers on a multi-layer printed circuit board. The sequential steps in forming a three-layer board are given in a flow chart (Fig. 4). The steps 1 to 7 produce an arrangement as shown, Fig. 1a wherein a relatively thick self-supporting copper sheet 10 is etched with cupric chloride to form lands a, b, c, d, e, f. The sheet or workpiece 10 is then laminated to an epoxy glass layer 11 by adhesive or by heat treatment under pressure and then cold pressing. The hot press curing process is described (with reference to Fig. 5, not shown). The laminate workpiece is then dipped in a catalyst, rinsed and dipped in an accelerator, rinsed and dipped into an electroless copper mix solution, rinsed and dipped into fluoboric acid and electroplated in a bath of cupric fluoborate to form an electroplated layer 10e (Fig. 1c) on the insulating layer and exposed lands. A circuit pattern is then formed thereon by a photo-etching process (Fig. 1d) and a further insulating layer is laminated thereon (Fig. 1e, not shown). The outer surface of the copper sheet 10 is then photo-etched to form a circuit (Fig. 1f) which is linked to the other circuit by the lands. Resistors, capacitors, inductors may be formed in the circuits by deposition. The finished board may be rigidly bonded to a rigid metal or plastics carrier by epoxy resin reinforced with glass fibre.

Title: Process for impregnating the surface of porous carrier material for the preparation of catalysts
IPC: B01J37/03
Filed: 1950-08-14
Abstract: In the preparation of catalysts by impregnating the surface of porous carrier material with solutions, e.g. of salts of platinum, gold, or nickel, the carrier is heated to a temperature above the boiling point of the impregnating solution and the solution is at a temperature close to or at its boiling point.  A carrier, e.g. of ceramic material, which has a low resistance to temperature changes, is heated to only a little above the temperature of the solution. The depth of penetration of the solution may be controlled by varying the temperature difference between the solution and the carrier. After impregnation the catalyst may be fixed by heating, oxidation, or reduction, and the steps of impregnation and fixing may be repeated.  Examples describe the coating of a porous alumina tube with platinum, and of ring-shaped bodies of sillimanite with nickel. In coating the inner surface of a tube, the impregnating solution may be passed through the tube.ALSO:In coating porous carrier material with metals to form catalysts by impregnation with solutions of salts of the metals and subsequent reduction, the carrier is heated to a temperature above the boiling point of the solution and the solution is used at a temperature close to or at its boiling point.

Title: Improvements in or relating to electron multipliers
IPC: H01J43/22
Filed: 1938-07-07
Abstract: 516,785. Electron multipliers. BAIRD TELEVISION, Ltd. (Fernseh Akt.-Ges.). July 7, 1938, No. 20162. [Class 39 (i)] An electron multiplier comprises an electron permeable secondary emitting electrode, means for causing an electron stream to strike the electrode, and for controlling it immediately after it has passed the electrode, and an output electrode for collecting the controlled electron stream, the controlling means being so disposed in relation to the secondary emitting electrode, that electrons emitted from the latter must deviate from the previous general direction of the stream in order to pass through the controlling means to the output electrode. The electron beam from a thermionic or photoelectric cathode 2 is multiplied at the electrodes 3. The low-velocity electrons emitted by the last electrode 3<1> are diverted by the field of electrodes 4, 5, 7 to the control electrode 4; the fast electrons which have passed through the electrode 3<1> continue to a collecting electrode 6, which may be cup-shaped, or coated with carbon, or screened bv other electrodes, so that no secondary electrons escape from it. The electrode 4, which may be carbon or chromic oxide coated to prevent secondary emission, modulates the beam before it passes to the permeable secondary electron emitting electrodes 5, and output electrode 6. The electrode 6 and say, one of the electrodes 5 may be connected. The first electrode 5 may be set at angle of 45‹ and be impermeable, so that the beam then travels parallel to its original direction and strikes the further electrodes 5, 7, which are set parallel to the electrodes 3. A second controlling electrode may be placed before the electrodes 3. When the cathode is photo-electric and the device is used for television, the electrode 4 may be used to impose the carrier frequency, and the second modulating electrode may impress synchronizing impulse on the signal.

Title: Apparatus for supplying rod-like articles (e.g., stubs for cigarettes)
Inventor: MOLINS DESMOND WALTER
IPC: H03F1/12
Filed: 1963-05-21
Abstract: 1,093,261. Feeding cigarette mouthpieces. MOLINS ORGANISATION Ltd. May 19, 1964 [May 21, 1963], No. 20194/63. Heading A2C. Cigarette filter stubs are fed by air through a conduit to a hopper at a faster rate than they are withdrawn therefrom by a fluted drum, the feed to the hopper being automatically stopped when the hopper is full. The stub feeding apparatus is shown in Fig. 1 with the hopper omitted. This apparatus comprises a guide 2 through which the stubs are fed by air, a stop 6 to arrest lengthwise motion of the leading stub and spaced more than the length of the stub from the passage, a support 22 on which the arrested stub is supported, a fluted drum 24 having its channels parallel to the arrested stub and laterally spaced therefrom, and a pusher 25 for moving the stub from the support 22 to a channel in the drum 24. A shaft 19, driven from the main machine drive, carries cams 18 30 and 40 which operate, though pivoted levers and cam follower rollers 9, 29 and 39 respectively the stop 6, the pusher 25 and a clamping device 31. The stubs are blown along the conduit 1 and guide 2 until the leading stub S1 is arrested by the stop 6 which is pivoted by the cam 18 at a distance slightly spaced from the end of the drum 24. Rotation of the cam 40 then operates the clamp 31 to hold the following stub S2. Further rotation of the shaft 19 rotates cam 18 to allow the stub 6 to move away from the end of the stub S1 into the position shown in Fig. 1 and finally rotation of the cam 30 operates the pusher 25 so that pusher members 26 push the stubs S1 into a channelon thedrum 24 for subsequent cutting into appropriate lengths. The stubs are aligned on the drum by a blade 43. Continued rotation of the shaft 19 causes the pusher 25 to be retracted, the stop member 6 to be moved back to its operative position, and the stub S2 to be released by the clamp 31. The stub S2 then moves into the position previously occupied by stub S1. Fig. 4 shows the apparatus with the hopper 100 included. The pusher pushes the arrested stubs laterally into a hopper at a slower rate than that at which they are supplied to the conduit, the stubs being removed from the hopper at a still slower rate by the fluted drum 24. A magnetic switch 103, 104 is provided to stop the stub feeding means supplying stubs to the conduit when a predetermined quantity of stubs is present in the hopper.
