Title: Apparatus for Measuring the Direction of Incident Sound Waves
IPC: G01S3/82
Filed: 1968-01-24
Abstract: 1,185,955. Direction finding. FRIED. KRUPP G.m.b.H. 24 Jan., 1968 [25 Jan., 1967], No. 3766/68. Heading H4D. In a system for determining the direction from which a sound wave arrives at a receiving transducer array, a compensator is provided comprising a tapped delay network for producing co-phasal transducer output signals and constructed such that continuous interpolation between the delay values of adjacent taps is obtained. In the Fig. 4 embodiment transducers E 1 - E 16  are connected to respective electrodes G 1 -G 16  (" transmitting switching elements ") arranged in the same pattern as the transducers. Tappings on delay network N are brought out to electrodes A 1 , A 2  &c. (" receiving switching elements ") and are coupled to electrodes G 1 -G 16  through a resistive fluid (e.g. copper sulphate or a mixture of mannitol, boric acid, potassium chlorite, water and alcohol) contained by housings 1, 3. The fluid ensures that each G electrode is coupled strongly to the nearest A electrode and also less strongly to adjacent A electrodes. For scanning different directions, housing 3 is rotated to shift the A electrodes relative to the G electrodes. By means of the continuous delay interpolation provided by the resulting variable coupling, good directional resolution is obtained with a minimum of delay tappings. The delay network output is fed to earphone or indicator 6 via sliding contacts 7, or via contacts arranged in housings 1 and 3 and coupled by the fluid.

Abstract: 824,007. Laminating. GLOBE ROOFING PRODUCTS CO. Inc. Feb. 4, 1957, No. 3848/57. Class 140. Laminated material is formed by feeding superimposed webs of thin metal, e.g. aluminium foil, and relatively thick material, e.g. asphalt-saturated felt, in superimposed relation along a common path, the confronting surface of the fibrous web having an adhesive previously applied thereto, and the thin metal web having edge portions extending beyond the corresponding edges of the fibrous web; bringing the metal web and the fibrous web together under pressure for motion along said common path; passing the superimposed webs while in motion between non-rotary edgeturning means to turn both edge portions of the metal web simultaneously around the edge regions of the fibrous web to define protecting edge flanges; and guiding the laminated web by the formed protecting edge flanges to effect alignment of the unturned parallel edges of the metal web with the edge-turning means which are mounted to float laterally with the web. As shown, a rectangular plate 46 is mounted in an inclined plane on brackets 49, 50. Transverse mounting shafts 47, 48 extend beyond the edges of plate 46 and are supported on rollers 53, 54, 58, 59, 60, 61 to permit the plate to float laterally. The laminated web is confined to the surface of the plate 46 by two series of rollers 66, 67 journalled on stub-shafts mounted on the channels 68, 69 disposed at the proper distance by means of brackets 70, 71, 72, 73 which are hinged to the plate 46 and provided with springs to press the rollers towards it. Elongated angular members 82, 83 fixed to the side edges of plate 46 retain the flanged laminated sheet in alignment with the plate. The edge-turning means comprises a pair of twisted plates 84, 85, fixed at their lower ends by means of brackets 87, 90 to the plate 46 to present a lower flat-surfaced portion 91, 92 parallel with the plate 46. The metal web and overlaps enter under the portions 91, 92 and as they pass up the plate are turned under the asphaltic web by means of the twisted plates 84, 85. Rollers 86, 88 apply pressure to consolidate the folded-over edges. Power-driven rollers (not shown) draw the laminate through the apparatus. One of them may be provided with an embossed surface to emboss the laminate. The completed laminate may be cut into sheets for building and other structural purposes.

Title: Methods and apparatus for the removal of metal by etching
IPC: C23F1/08
Filed: 1966-01-28
Abstract: 1,124,760. Etching. CHEMCUT CORP. 28 Jan., 1966 [15 Feb., 1965], No. 3858/66. Heading B6J. [Also in Division G3] A variable speed conveyor carries articles through an etching zone, a control wire, which is of the same material as the articles to be etched, being exposed to the etchant and driven in synchronism with the conveyor. The length of the control wire under attack by the etchant is sensed to decrease the conveyor-speed in response to a decrease of the etch-rate. The control wire 92 is fed into sample tank 56 by rolls 102 coupled to conveyor motor 62, the etchant forming a stub 110 which is continuously fed toward conductive plate 112. When relay 116 is unactuated due to wire stub 110 being shorter than a reference value, motor 120 drives slider 124 to increase the speed of the motor 62. The speed of the conveyor motor is reduced when relay 116 is actuated due to bottoming of the stub 110 against the plate 112. In a modification, a mask has a relieved V-shaped portion with which the control wire in the sample tank co-operates to define a light gate between a lamp and photo-resistor. When the resistor is illuminated by an open gate, the speed of the conveyor is increased. The speed is decreased when the photo-resistor is darkened by a closed gate formed by an increase in length of the control wire. In a further embodiment, the mask has relieved portions to define first and second light gates associated with photo-resistors at different levels with respect to the sample tank. The speed of the conveyor is increased in response to opening of both light gatos, and is decreased when both gates are closed by movement of the control wire. A uniform speed of the conveyor is maintained when the first light gate is closed and the second is opened. The wire may be passed in a loop through the etchant in a sample tank, the conveyer speed being adjusted in accordance with the thickness of the wire as it emerges from the tank.

[Also in Group XXXIV] In a mechanism for bleeding hydraulic brakes, a ram and two-way change-over valve are so arranged that when the ram is installed in a motor vehicle or the like the foot brake pedal of the vehicle may be reciprocated by remote control from anywhere around the vehicle and the operation of bleeding hydraulic brakes carried out by one person. The apparatus consists of a pneumatically-operated ram 1, having at one end a clamp 11 which may be secured to the foot-brake pedal pad of the motor vehicle, the other end being pivoted at 14 to a plate 15 carrying two legs 16 (not shown), 17 ; the plate to bear against the front of the driver's seat, the legs to rest on the floor of the vehicle. The ram is supplied with compressed air from a source through a two-way changeover valve 21 which is so constructed as to permit flow of compressed air from a source via flexible hoses 36 and 37 to operate the ram plunger tube 4 when the plunger 26, in the twoway change-over valve 21, is depressed by the right-hand side of the finger-operated rocking bar 38. The ram plunger tube 4 thus depresses the foot brake pedal. When it is desired to return the foot brake pedal to its inoperative position, the left-hand side of the rocking bar 38 is depressed, thus opening the plunger 27 and allowing the air in the ram 1 and hose 37 to be exhausted to atmosphere. Thus alternative right and left depression of the rocking bar 38 will impart a reciprocating motion to the ram plunger tube 4 and thus to the foot-brake pedal of the motor vehicle, the return stroke of which is operated by the return spring normally attached to the pedal.
