Title: Method for image enhancement in positive photoresist by vapor diffusion image reversal
Inventor: STAUFFER CRAIG M
IPC: G03F7/20
Filed: 1985-07-23
Abstract: An image reversal method for forming a negative image on a surface using positive photoresist material includes the first step of coating the positive photoresist material on the surface, and soft baking the photoresist or the like to form a uniform layer on the surface. The photoresist layer is then exposed by actinic radiation through a mask or the like in image forming fashion, the exposed portions reacting to form a carboxylic acid or other acid which is soluble in aqueous base solutions. The photoresist is then exposed to a treatment with a vapour of chemical base (e.g. of an amine; tetramethylammonium hydroxide, triethanolamine or ammonia) which renders the acid insoluble to alkali solutions and relatively insensitive to further light exposure. The vapor treatment is followed by a flood exposure of the entire surface to render soluble the photoresist portions which were originally unexposed by the mask. The photoresist is then developed by immersion in an alkali developer to remove the flood exposed portions. The remaining photoresist areas comprise the mask exposed portions in relief from the surface and defining the negative image of the original mask exposure.

Title: Test head for compressed gas cylinders
Inventor: GRENCI CARL A
IPC: G01N3/12
Filed: 1985-08-02
Abstract: A test head useful in the testing of compressed gas cylinders capable of withstanding high pressure. The water jacket head includes a neck seal including a spud insertable into the neck of a compressed gas cylinder for permitting a high pressure seal to be made to the cylinder. The present neck seal incorporates a permanent quick-connect sleeve for which mating male spud insert units can be designed for nearly any size cylinder neck. Changing the spud insert can be accomplished by hand, without removing the head from its use location. A diaphragm support spring is installed between the moving spud stem assembly and the top plate of the head which biases the spud stem assembly, thus increasing diaphragm life and preventing increasing reassembly difficulty following spud changes. Studs and screws replace welds in holding the top, side and bottom plates together which greatly alleviates the task of servicing inside the head when leaks eventually occur in the moving elements. A heavy, long-lasting, fluid pressure expansible head boot is included which requires less servicing, simplifying field installation.

Patent GB-860079-A (GB)
Abstract: 860,079. Ticket-issuing machines. MYCALEX & T.LM. Ltd. May 25, 1959 [May 23, 1958], No. 16681/58. Class 106 (3). A machine which prints and issues tickets in any one of several ranges of values has discs from which a variable number of teeth project in order to actuate counters. Disc 7 has a pair of laterally extending spur - teeth 16; each pinion 17 around the circumference of the disc has three wide teeth 20, three teeth 21 of half width and a counter actuating tooth 22 which has an inactive and an active position. Rotation of selector knob 1 causes rotation of the disc 7; the teeth 20 of each pinion are locked against the circumference of the disc until a tooth 21 engages a spur tooth 16 causing pinion 17 to rotate until the next pair of teeth 20 are locked against the circumference of the disc; tooth 22 then projects from the disc. The setting of the selector knob 1 thus determines how many teeth project from disc 7. When the entire mechanism is rotated by a handle 25, each projecting tooth 22 actuates the counters 24 through star-wheel 23. After the teeth of each pinion have been set, they are maintained in that position during rotation of handle 25 by a spring-urged detent 42 which engages in depressions in a locking disc 13; when the mechanism is in its rest position, the detent is opposite, and is spring-urged into, a depression in the fixed casing away from, and freeing, disc 13. Discs 8 and 9 are similarly arranged to register in different ranges of values. Printing mechanisms 32, 33, 34, axially arranged relative to the counter-actuating-mechanism, are actuated through gears 29, 30, 31 which co-operate with gears 10, 11, 12 on discs 7, 8, 9,

Title: Making printed circuit boards
Inventor: LEWIS JOHN DIDWITH
IPC: H05K3/00
Filed: 1987-03-11
Abstract: An electrical circuit is formed on an insulating substrate (1) by selectively etching a thin copper foil (2,3). The foil is masked by means of an etch resist layer (4,5) which is sensitive to ultra violet light. The layer of resist (4,5) is initially continuous and is covered by a coating (6,7) of a photo-sensitive emulsion on which a circuit pattern is written by a visible or infra-red beam of light to selectively render regions of the coating opaque or light transmissive. The underlying photo-resist layer is then exposed via the light transmissive regions using a high energy ultra violet light source (8) to form the desired circuit pattern in the resist. The unhardened regions of the resist, together with the overlying coating (6,7), are chemically removed and the exposed copper is etched away to form the required circuit. <IMAGE>
