[Class 41] [Also in Groups XXII, IV, XIII, and XXIII] Mechanically roughened foil, for use as an electrode in electrolytic condensers &c., may be subsequently chemically or electro-chemically etched. The process may be that described in Specification 467,024. Alternatively, the strip passes from the bath E to a bath G, Fig. 3, of sodium chloride solution and travels between electrodes G<SP>3</SP> connected to the negative lead of a source of current H, while a brush H<SP>1</SP> connected to the positive lead bears on the foil. The electrodes may be formed of the alloy sold under the Registered Trade Mark "Monel." The bath is maintained at boiling point either by the electric current alone or by a separate heater. The strip is then washed by sprays K<SP>1</SP>, passed through a bath M of isopropanol, and dried over an electric heater O<SP>1</SP>. Alternatively, the isopropanol is sprayed on to the foil. The tendency to etch the upper surface to a greater extent than the lower surface may be compensated for by passing the film through the bath closer to the lower electrode G<SP>3</SP>, Fig. 4. The use of electrodes G<SP>4</SP>, G<SP>5</SP>, Fig. 5, comprising series of parallel rods leads to uniform boiling and the free escape of gases.

Title: Improvements in or relating to focal plane photographic shutters
IPC: G03B9/34
Filed: 1938-11-04
Abstract: 520,959. Photographic cameras. KODAK, Ltd. Nov. 4. 1938, No. 31996. Convention date, Nov. 13, 1937. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 6, 1939.] [Class 98 (i)] A focal-plane photographic shutter comprises a pair of curtains which are wound under tension on to a roller, and means to prevent unwinding of the curtains during this operation, is provided with means to prevent release of the shutter except when fully wound comprising a latch for one of the curtains which, when the shutter is fully wound, is operatively engaged by the shutter release member, but in any intermediate position, is out of the path of the release member. The invention is described in connection with the shutter described in Specification 520,957, in which a shaft 56 has loosely mounted on it a gear 63 carrying a pivoted pawl 60 which engages a single-tooth ratchet 58 on the shaft. During winding. of the shutter the shaft 56 is rotated through one revolution, the pawl 60 engaging the ratchet 58 so that the gear 63 is also turned and rotates the shutter roller through intermediate gears. Operation of the shutter release causes a lever 72 to move clockwise about its pivot 73 so that a lug 82 on it engages the end of the pawl 60 and releases the pawl from the ratchet 58, allowing the gear 63 to turn under the pull of the shutter curtain. Only when the shutter is fully wound can this release action occur, since at intermediate stages of the winding the gear 63 carries the pawl out of the path of the lug 82. Specifications 513,738 and 520,954 also are referred to.

Title: Flow control system
IPC: F02K7/16
Filed: 1972-10-30
Abstract: 1401018 Gas turbine ducted fan engines BOEING CO 30 Oct 1972 [8 Nov 1971 16 Feb 1972] 32205/74 Divided out of 1401017 Heading F1J [Also in Division F2] The invention relates to a flow control system comprising means for inverting the respective positions of two separate flow patterns between the inlet and outlet of the system, there being means for switching the flow patterns whereby the flow patterns may be non-inverted. The system is shown applied to a gas turbine ducted fan engine in Fig. 1, the flow of air A from the fan 26 and flow of air B from the intake 28 are inverted in passing through the flow control unit 20 so that the flow A which is radially inward of flow B at the inlet 22 is radially outward of flow B at the outlet 24. The flow A discharges through propulsion nozzle 30. The flow B passes to the compressor 32 of the gas turbine engine. Thus the engine acts as a ducted fan engine. The downstream portion 24 of the flow control unit may be rotated so that the unit does not cause flow inversion, the inner flow A from the fan 26 now passing to the inlet of the compressor, and the outer flow B now passing straight through from the intake 28 to the outlet 30, the engine thus acting as a straight-through gas turbine jet engine. A flow control unit is shown in Fig. 3 and the cross-sections taken at the planes 3a, 3b, 3c, 3d, 3e, 3f are shown in the corresponding Figs. A passage A at the inner radius at the inlet section 3a, becomes passage A at the outer radius at the outlet section 3f; the cross-sections of the passage A changes from an arcuate sector at section 3a, to a pentagonal section at 3b, to a triangular section with apex outward at 3c, to a trapezium section extending from the inner wall 62 to the outer wall 60 at 3d, to a triangular section with apex inward at 3e, to a pentagonal section, finally to an arcuate sector at 3f. The control unit is divided at the section 3d, the downstream portion 58 being angularly movable with respect to the upstream portion 56 whereby the flows may be inverted or not. The control member may alternatively be built-up from a series of duct portions as shown in Fig. 6 each of which has a rectangular opening 140 at the inlet end, the rectangle having the longer side of horizontal, the duct changing to a triangular section at 142 then to a rectangular section at the outlet 144, the rectangle having the longer side vertical. In Fig. 7, two such duct members 126, 126" are joined end-to-end and a similar pair of members 126''', 126"" are disposed to co-operate therewith. The downstream members 126''', 126"" are arranged to move laterally with respect to the upstream members 126', 126 " for control. The area of the duct at any point along its length is constant. Many applications of the invention are described.

Filed: 1939-12-18
Abstract: 534,103. Electromagnetic switches; motor controllers. HINKS, B. Dec. 18, 1939, No. 32411. Addition to 524,015. [Classes 38 (iii) and 38 (v)] In an electro-magnetically-operated switch of the kind described in the parent Specification, the contact-carrying member 14 is connected to the armature 5a by links 15 which also carry a weighted member 16. When the electro-magnet 4 is energized the armature 5a moves down against the action of springs 9. The weighted member 16 which rests on the armature, also moves down and the contacts on the member 14 move so as to complete a "star" connection for the motor. A projection 14c also engages a thermal element 17 which'after a time interval during which it heats up, moves so as to break the circuit to the electromagnet. The springs 9 now rapidly move up the parts 5a, 16, 14, till the armature 5a engages the frame 11 and stops. The momentum of the member 16 causes it and the member 14 to continue moving upwards and also sideways, thereby causing a fork 18 to move a contact spring 19 into engagement with a fixed contact and again close the circuit to the electromagnet. The armature again descends, but the member 14 is now further to the right and is guided downwards so as to engage the " delta " contacts of the motor.
