Title: Methods of and electrical connectors for making electrical connections to fine insulated conductors
IPC: H01R4/24
Filed: 1974-01-28
Abstract: 1411932 Coupling member AMP Inc 28 Jan 1974 [16 Feb 1973] 03775/74 Heading H2E To connect an insulated conductor, primarily very thin, to a connector 4, the contact surface 25 of the connector is coated with a film of relatively hard metal having sharp protruding abrasive particles embedded, either by codeposition from a stirred bath, or by spraying, to give only partial coverage with abrasive. Optionally a top electro-deposited film of soft metal covers abrasive and intact hard film, in which case the abrasive need not be conducting, e.g. ceramic. To connect a flat strip conductor 2 to connector 4, the strip is bent round block 24, and slide 18 in former 5 is screw-adjusted 20 so that the abrasive on connector 4 fitted over pin 22 penetrates the insulation when the block is slid into cavity 16, after which screws 20 are tightened to make permanent contact, the soft metal film being forced into the punctures in the insulation. In the example the conductor is 0À0010-0À0015 inch Cu strip with on both faces 0À0008 inch layers of polyamide-imide or polyethylene terephthalate insulation. The connector 4 is of 0À004 inch metal, coated with W carbide or hard Ni particles of 0À0008 inch mean size, at a density of 150 per square mm. in a Ni film 0À00013 inch thick lying between and over the abrasive particles; and with a Sn or soft Au film cover. In a connector for an I.C. chip potted into circuit unit 36 (Fig. 7) with abrasive faced connectors 40 on its periphery, circuit panel 41 with thin insulation over internal conductor strips 38, is fitted with its edges ready to be bent down the sides of an opening in support member 44. On inserting unit 36, the abrasive penetrates the insulation and contacts the underlying conductor opposite each connector 40. A tubular connector with internal abrasive covered walls may be connected to a thin insulated wire by insertion over the wire drawn across the mouth of a stuffer plug (Figs. 8, 9, not shown). Two orthogonal wires may be connected, or if the second is to be inserted later, two short stuffers allow a first and second connection. Fine wires from a computer magnetic core memory may be connected to a connector 11 made from stiff plastics in zig-zag form, with the surface only in the troughs metallized and coated with abrasive, forming multiple connector surfaces (Figs. 10, 11, 12, not shown). With variation of insulation thickness on the conductor, in any embodiment, the mean size of the abrasive particles is selected in proportion.

Title: Device for regulation of secondary air supply in modulating oil burners
IPC: F23N5/00
Filed: 1965-01-28
Abstract: 1,055,862. Automatic smoke control. R.L. JOHANSEN. Jan. 28, 1965, No. 3865/65. Heading G3R. In an oil fired boiler control system in which the fuel supply is automatically regulated in proportion to the load on the boiler, secondary air supplied to the burner is automatically regulated by a motor-operated damper which is operated when necessary by a relay controlled by a photocell exposed to light transmitted through the boiler flue, and stopped at other times by a brake. As described, two photo-conductive cells associated with electronic relays are used so that when smoke density rises above a predetermined value one cell causes a motor to operate in one direction to open the damper, and when the smoke density falls below a predetermined value, the other cell causes the motor to close the damper. When the smoke density is between the predetermined limits the motor is braked by D. C. applied to an auxiliary stator winding.

Title: Combined catalytic cracking and naphtha reforming process
IPC: C10L1/06
Filed: 1974-01-29
Abstract: 1455161 Gasoline EXXON RESEARCH & ENG CO 29 Jan 1974 04075/74 Heading C5E High clear octane gasoline is obtained by catalytically cracking a hydrocarbon feed to produce a C 5 /430‹ F. fraction, fractionating the C 5 /430‹ F. fraction to produce a light fraction, an intermediate fraction of relatively low octane number and a heavy fraction, catalytically reforming at least a portion of the intermediate fraction, and blending the reformate with the light and heavy fractions. A feed, e.g. a gas oil boiling between 600‹ and 1050‹ F., from a heater 2 is passed from a riser cracker 4 into a dense bed of catalyst in a fluid catalytic cracker 8. The cracking can be carried out at 700- 1200‹ F. and 5-100 p.s.i.g. using a catalyst such as a 10% Mg-faujasite embedded in 90% silica gel or a 25% alumina-75% silica amorphous gel catalyst. The cracked product 23 is separated at 24 into a light C 5 /180‹ F. fraction, an intermediate 180-270‹ F. fraction and a heavy 270-430‹ F. fraction. The intermediate fraction 28 is reformed in a series of reformers 34, 36 and 38, e.g. at 825-1000‹ F. and 100- 1000 p.s.i.g., e.g. with a catalyst comprising 0À05-1% Pt and 0À05-1% halogen on activated alumina or comprising cobalt molybdate on activated alumina. The reformed fraction is cooled and, after the separation of recycle hydrogen 50 at 46, is blended with the light and heavy fractions at 26. The cracking catalyst is regenerated at 15 by burning off coke with air 14 and recycled and the reforming catalyst can be regenerated in a swing reactor 54. The intermediate fraction can be reformed together with other reformer feed or can be extracted to provide an extract, which is blended with the light and heavy fractions, and a raffinate which is reformed and then blended with the light and heavy fractions.

Title: Improvements in or relating to television and like cameras
Inventor: HALEY DONALD GEORGE
IPC: H04N5/228
Filed: 1963-02-01
Abstract: 1,021,143. Television. MARCONI INSTRUMENTS Ltd. Nov. 26, 1963 [Feb. 1, 1963], No. 4157/63. Heading H4F. The charge-storage target 4 (Fig. 1) of a storage type image-signal generating tube is fed from a carrier source 8 of frequency high (e.g. 8-70 Mc/s.) relative to the highest video frequency produced and having a peak-to-peak amplitude (e.g. 4 volts approximately) which, in the presence of a charge image on the target, causes the potential of the latter to oscillate (at the frequency of source 8) between a value at which scanning electrons from gun 2 can land on the target and a value at which they cannot land so that the video modulation of the return electron beam is " chopped " at the frequency of source 8 and results in the production of a component in the output derived from electronmultiplier 3 comprising a carrier wave of the frequency of source 8 amplitude modulated by the video information. By means of a tuned band-pass transformer 12 one or both of the modulation side-bands 15 are selected and supplied by a transistorized amplifier 13, in which the required blanking is effected from a blanking source 14, to a demodulator 15 from which the video signal is derived for normal utilization. Owing to the presence of the high-frequency carrier decoupling of certain ones of the tube electrodes is necessary and capacitors 18 are provided for this purpose. Advantages claimed are: No loss of high-frequency video since the output capacity of the final electrode of the multiplier forms part of the carrier frequency band-pass load; no " shading " signals or other spurious signals are produced by the dynodes (of the electron-multiplier) due to pick-up from the scanning coils; the transformer 12 replaces the conventional high voltage coupling capacitor, eliminates risk of damage to the first stage of the transistor amplifier and facilitates impedance matching. High-frequency transistors (in amplifier 13) have lower noise ratings than comparable video frequency transistors; automatic gain control (of amplifier 13) at high-frequency is simpler than at video-frequency; " black " level is represented by zero amplitude carrier and is automatically set at demodulator 15. Impingement of internal metal work of the tube by an over-deflected scanning beam results in the production of a " black " signal which does not upset the automatic gain control circuit.
