Title: Improvements in or relating to electric-circuit selectors
IPC: H01R24/58
Filed: 1959-03-17
Abstract: 934,627. Plug boards and two-part couplings. SEALECTRO CORPORATION, and S. T. DEAKIN. March 11, 1960 [March 17, 1959], No. 9176/59. Class 38 (1). An electric circuit selector comprises upper and lower insulating plates 1, 2 on which are mounted rows of contacts 9, 8 respectively, the plates being spaced by pillars 3. Each row is constructed by bending a silver-plated copperberyllium blank to channel form, the side walls of the channel being divided into pairs of opposed contact sections and the base of the channel opposite each pair of sections being cut to form a hooked tongue 15 which extends lengthwise of the channel. A row of contacts is assembled on a plate 1 or 2 by passing the tongues 15 through holes 6 and moving the channel lengthwise to engage the limbs 15a of the tongues with the portions of the plate surrounding the holes. The rows of contacts are then locked in position by contact strips 21, 24 which are soldered or welded to the last tongue 15 of the rows and which provide means for connecting the rows to an outside circuit. A cover-plate 18 is secured to the plate 1 by means of the pillars 3 and the limbs 15a of the tongues are clamped between the plate 1 and the coverplate 18. Contact between vertically aligned contact sections is made by means of connecting pins 20 which pass through holes 19 in the coverplate, Fig. 2. In a modification, Fig. 6, the cover-plate 18 is replaced by a plate 30 in which there are slidable insulating bushes 32 containing a socket 34 attached to a contact pin 35. A spring 36 urges the bush upwardly, but the pin is retained in the depressed position by the engagement of a contact 8 in a groove 38 in the pin. The socket 34 is for the reception of a test plug 39, and the upper part of the pin may be coated with insulation material so that when the pin is in the chain-line position, connection is made between the socket and contact 8 only. In Fig. 7 the contacts 9 are earthed by means of a metal plate 1a and the lead wire 41 of a screened lead is connected to a contact pin 40. A further modification, Fig. 8 (not shown), comprises a jack plug connected to two separate wires. In Fig. 9, separation and screening of the individual contacts 8, 9 is provided by partitions fitted in the manner of egg-box partitions. Each partition consists of a sandwich of a metal layer 62 between two sheets 63 of insulating material and the layer 62 is earthed. The single tongues 15 may be replaced by a pair of tongues and a contact tag may be formed by the end of the channel base. The contact sections may be approximately semicircular in form to provide a cylindrical socket.

Title: Integrated semiconductor circuit
IPC: H01L27/00
Filed: 1972-03-02
Abstract: 1320884 Integrated circuits INTERNATIONAL BUSINESS MACHINES CORP 2 March 1972 [30 March 1971] 9707/72 Heading H1K An integrated circuit master slice is formed into a specific circuit arrangement by the provision of surface metallization to interconnect some of its electrically isolated circuit elements (transistors and resistors) with some of its peripheral terminals. The slice is flip-chip bonded to lands on an insulating substrate, the lands being connected by tracks to terminal pins. Where it is necessary for a track to reach its pin by passing across the substrate between its surface and the attached slice the track must (because of the limited space available) contact a terminal elsewhere on the periphery of the slice; this terminal is chosen to be one not used in the specific circuit arrangement. During manufacture of the slice D.C. sputter cleaning may be used and this can lead to dielectric breakdown under floating terminals, and so, to avoid short circuits, the selected non-used terminal is connected to a non-used circuit element during (and after) manufacture thus providing a situation in which the sputter etching may be carried out without dielectric breakdown under the terminal.

Title: Improvements in and relating to cryoclectric memories
IPC: G11C11/44
Filed: 1965-03-09
Abstract: 1,082,124. Superconductive memory arrays. RADIO CORPORATION OF AMERICA. March 9, 1965 [March 16, 1964], No. 9905/65. Heading H3B. [Also in Division H1] In a continuous sheet cryoelectric memory the return conductor for the drive currents lies over a surface of the superconductive memory plane for substantially its whole length. This reduces noise in the sense line due to radiation from the unshielded leads. The drive and return leads may be arranged parallel and both located above the sense plane to reduce noise due to penetration through the memory plane of the field associated with the drive current, as shown in Fig. 4. The return leads may be branched and interleaved with the drive conductors. The sense plane is preferably as shown in Fig. 5, having two slots 90, 92 defining outward and return paths 91, 93 and 95, joined at corner 94. Terminals 96, 98, 100 are connected to two primary windings on a transformer so that sense signals are additive and produce an output in winding 112, whereas noise currents cancel. In a modification (Fig. 7, not shown) the superconductive plane forms the current return path for sense signals, being joined to the sense plane at the corner opposite to that at which connections are made. Both the memory plane and the sense plane have extensions leading to terminals connected to an output transformer the extension on the memory plane being wider than that on the sense plane and being connected to two terminals, one on each side of the sense plane terminal.
Patent GB-191104936-A (GB)
IPC: F23Q21/00
Abstract: 4936. Rousset, F. Rossbach-. March 19, 1910, [Convention date]. Valves controlled from a distance.-In apparatus for controlling the valves of gas burners by means of mechanism operated by a yielding pressure member, a gas chamber 11, separated from a chamber 10 by a diaphragm 9, is temporarily placed in communication with the atmosphere by an outlet valve 18, controlled by the diaphragm, each time the burner valve 1 is operated. The gas enters at 7 and passes through the chamber 5 and passage 15 to outlets 12, 13 leading respectively to chambers 10, 11. The throttling-screws 16, 17 are so adjusted that a difference of pressure only exists in the chambers 10, 11 when a rapid and definite rise of gas pressure takes place. When this occurs, the increase of pressure in the chamber 11 acts on the diaphragm to lift a lever 27 and pawl 25 to open the outlet valve 18. By this means, the pressure in the chamber 11 is reduced, and the diaphragm readily moves into its fully-extended position. The head 34 of the rod 32 then rotates the ratchet wheel 41 through levers 35, 38, 40, and operates the burner and pilot valves 1, 3. Owing to the springiness of the lever 35, the diaphragm is able to make a further stroke, by means of which the cam-face 28 of the pawl 25 contacts with the inclined surface 29 and releases the valve 18, which at once closes under the action of the spring 21. The gas pressure in the chambers 10, 11 is then gradually equalized, and the parts return to the normal positions. For quickly returning the diaphragm, a construction is described in which a valve in the chamber 11 establishes communication with the supply-pipe 7 after the burner valve has been operated.
