Title: A method for making a predetermined metallic pattern on an insulating base
IPC: H05K3/06
Filed: 1953-10-09
Abstract: 724,379. Ornamenting. GENERAL ELECTRIC CO. Oct. 9, 1953 [Oct. 10, 1952], No. 27856/53. Drawings to Specification. Class 93. [Also in Group XXXVI] A metallic pattern is formed on an electrically insulating support by bonding a relatively thin metal foil to one surface of the support, forming a plating-resistant coating over the foil except in selected areas where the pattern is to be formed, electroplating the selected areas with a lead-tin solder, removing the plating resistant coating and etching away all exposed portions of the foil not protected by the solder. The plating-resistant coating may comprise a lightsensitive channel, over which a transparency, having opaque portions corresponding to the desired pattern is placed. The assembly is exposed to light, after which the unexposed portions of the enamel are removed by a developing solution and the assembly is made the cathode in a plating circuit, the anode being a lead-tin rod. The enamel acts as a plating resistant coating, so that only the exposed portions of foil are plated. The enamel is then removed from the foil and the assembly immersed in an etching solution to remove the unplated parts of the metal foil. A pattern may be similarly formed on the other surface of the support.

Title: Improvements in and relating to coating apparatus
Inventor: STRANGE JOHN WILLIAM
IPC: B05B14/00
Filed: 1956-09-12
Abstract: <PICT:0829573/III/1> <PICT:0829573/III/2> Apparatus for coating the interiors of lamp bulbs with a suspension comprises a chamber 1 for the suspension which is in communication with the atmosphere, a filter 2 in the chamber, a pump 4 connected to draw the suspension continuously from the chamber 1 through the filter 2 to a nozzle 6, having at least one continuously open orifice through which the suspension flows continuously during operation of the pump, means for returning excess suspension from the nozzle 6 to the chamber 1, e.g. a trough 7 and a pipe 8, and means, e.g. a valve 10 in a by-pass pipe 9, for controlling the flow of suspension delivered through the orifice.  The valve 10 may be automatically regulated by means responsive to the positioning of a bulb over the nozzle 6, the valve 10 being then wholly or partly closed, the suspension then being emitted from the nozzle orifice in the form of a jet.  A loose-fitting lid 3 on the chamber 1 permits the suspension to communicate with the atmosphere.  Returning suspension entering the chamber 1 by the pipe 8 serves to stir suspension in the chamber 1, the filter 2 being provided above an outlet pipe 11.  In a modification, the valve 10 is retained, but regulation of flow of suspension from the nozzle 6 is provided by subsidiary orifices, e.g. longitudinal slits in the side walls of the nozzle and an external coaxial sleeve valve on the nozzle 6 which is rotated to close the slits during a coating operation, e.g. by engagement of a bulb with a handle on the sleeve.  In another modification, Fig. 4, the nozzle 6 is slidable on the end of a pipe 5 leading from the pump 4 and is normally upwardly urged by a spring 21 to maintain subsidiary orifices 24 in the side walls of the nozzle 6 above the end of the pipe 5.  The placing of a bulb on wings 26 on the nozzle 6 forces down the nozzle 6, the pipe 5 closing the orifices 24.  A stop 19 working in a slot 20 in the wall of the nozzle 6 limits vertical movement of the nozzle 6.  A baffle 25 directs suspension emerging from the orifices 24 to the trough 7.  More than one main orifice 23, and only one subsidiary orifice 24, may be employed, and according to the Provisional Specification, one orifice only may be provided in the nozzle 6, the effective area of the orifice being varied to control the delivery of suspension from the nozzle 6.

If key 8 is pressed, current flows through relay 4, key 8, rectifier 7, and relay 5, causing the latter to respond. If key 9 is pressed relay 4 responds. If both keys are closed simultaneously both relays respond. In a modification shown in Fig. 2, the polarized relays are replaced by relays 16, 17 which are not polarized but are bridged respec tively by rectifiers 14, 15.

Title: Rolling Bearings Particularly Intended for Tube Segments of a Jet Deflector of Jet Engines.
Inventor: KOPP GERHARD
IPC: F02K1/00
Filed: 1967-05-19
Abstract: 1,167,070. Bearings. ENTWICKLUNGSPRING SUD G.m.b.H. 19 June, 1967 [27 June, 1966], No. 28272/67. Heading F2A. In a ball or roller bearing for a tubular part of a jet engine, an expansion body is heated electrically and, via contacts as well as a measuring and control device, is in operating connection with a switch for the automatic adjustment of the heating temperature, so that by switching on and off the electrical heating and continuously changing the heating power, the amount of the bearing play is controlled by the relative axial adjustment of the race and rolling members. In an embodiment, an expansion body 35, Fig. 1, is mounted between two sets of rollers 46, each set having an inner race 45 formed on member 42, 43 or 44 of a jet-deflector of a jet engine and an outer race formed by steel buffer rings 38 supported by spacers 37. The expansion body 35 carries the spacers 37; contains heating wires 36; and is mounted in a groove 34 of a tube member 31, 32 or 33 of the jet deflector. The heating-wires 36 are connected by electrical leads 50 to a contact spring 51, which has one end mounted on the tube member 31, 32 or 33 and has the other end in contact with a resistor 62, the latter is mounted on the member 42, 43 or 44 and is provided with a rest-contact 61. When the bearing play is nearly zero, the spring 51 is in engagement with the rest-contact, consequently, the heating-wires are not supplied with electricity; but when the tube members of the jet-deflector expand due to being heated, the contact-spring 51 leaves the rest-contact 61, causes a relay to close a switch 57 of a circuit 50, 54 and 55 and thus allows electricity to flow through the wires 36 in the expansion body 35. A potentiometer is provided and is adjusted, by either the contact spring 51 or the resistor 62, to control the degree of heating and thus compensate for the bearing play. The heating is automatically terminated when the tube members contract, the spring 51 then re-engaging the rest contact 61. In another embodiment, heating coils 36 in an expansion body 35, Fig. 4, are supplied with electricity supplied by a generator 90, Fig. 5, which is in a secondary circuit 100 and electricity is passed to the heating coils 36 of the expansion body 35 so as to control the bearing clearance. When the pressure of the fluid in the primary circuit 70 increases to a predetermined amount, a relief valve 72<SP>1</SP> opens and effects the actuation of a motor 73 to move a jet deflector.
