Title: Photographic Slide Storage System and Multiviewer.
Inventor: CROOKES WILLIAM
IPC: G03B21/64
Filed: 1966-10-13
Abstract: 1,161,130. Filing papers. W. CROOKES. 10 Oct., 1967 [13 Oct., 1966], No. 45721/66. Heading B6E. [Also in Division G2] A device for storing and viewing photographic transparencies comprises a transparent sheet 1, on which are secured rows of pockets 2 in which the transparencies are placed. To prevent them from falling out of the open edge of the pockets, these are covered by flaps 13. The sheet 1 is hinged along one edge 4 to a stiff card 3, which has punched holes 5 by which the card can be mounted on a lever-arch type of filing means 6. Thus several such assemblies can be mounted on the means 6 in the manner of a loose-leaf filing system. When not in use, the sheet 1 is folded over to lie flat on the card 3, and the folded assemblies lie in a stack on a baseboard 9. In order to view a set of transparencies, sheet 1 is unfolded so as to lie on the translucent top panel 11 of a box 10 containing a lighting unit. Thus any one of the assemblies stacked on the device can readily be brought into the viewing position.

Abstract: 1,095,019. Circuit assemblies; capacitors. ILLINOIS TOOL WORKS Inc. Oct. 29, 1965, No. 45892/65. Headings H1M and H1R. A component assembly comprises an insulating rectangular wafer, Fig. 10A, having metallized peripheral notches 56, 60, 62 &c., joined by printed wiring to terminal areas on both faces of the wafer; on each face flat carbon tape resistors such as 88, 90, 92 are connected between selected terminal areas, and each resistor is overlaid by a wound capacitor such as 20d, 20e, 20f, connected at one end to a terminal area which in one case (Fig. 9, not shown) is in common with the underlying resistor, and at the other end to a separate terminal area. The resistors are connected to intermediate as well as end terminal areas, to increase the values of resistance available between selected riser wires (not shown) which fit into the notches. A plurality of wafers may be stacked, and the assembly may be-encapsulated. Capacitor construction.-Fig. 2. The capacitors, each about 1/4 in. in length, are made in pairs. Two metal (e.g. tin) foils 24, 26 are laid in spaced parallel relation between two strips 22 of insulating material (e.g. polyethylene terephthalate), a third foil 28 is laid on the upper strip 22 overlapping foils 24, 26, and the whole is wound into the convoluted form shown. The assembly is then divided centrally by a cut perpendicular to its axis, the outlying portions of foils 24, 26 are cropped off, and leads are fixed to the two resulting capacitors. The leads may be of Z-section (Figs. 4, 5, 6, not shown), or of circular section wire (Fig. 7, not shown). The capacitance of each capacitor is determined by the degree of overlap between foils 24, 26 and foil 28.

Abstract: 1,082,229. Gas lighter filling valves. JAPAN GAS LIGHTER ASSOCIATION. Oct. 29, 1965 [Oct. 31, 1964], No. 45949/65. Heading F4F. A gas lighter filling valve comprises a valve stem 141 having a shoulder 136 which when the valve is closed, Fig. 1 (not shown), abuts the bottom end of a sleeve 118 threaded to the lighter casing 100 and defining an inlet passage into the lighter reservoir. An extension 130 of the stem 141 extends into this passage and terminates in a dished plate 150 having an aperture 151 therein. A refill vessel 162 when depressed against the plate 150 causes the valve to open against the action of a spring 128 and liquefied gas passes through aperture 151 while displaced air passes to atmosphere between the plate 150 and the inner walls of a narrow portion 170 of the sleeve 118. The valve stem 141 and spring 128 are housed in a cylinder 112 threaded to the sleeve 118 and having radial ports 122 communicating with the reservoir.

Abstract: 990,149. Spray-producers; coating apparatus. DE VILBISS CO. Nov. 28, 1963 [Dec. 13, 1962], No. 46995/63. Headings B2B and B2F. An apparatus 10 suitable for spraying coating material such as paint on to an article 12 comprises a spray head 48 designed to spray the paint generally radially from an edge 68, said head being maintained at a first potential by a voltage source 84, a field ring 70, Fig. 2, located concentrically with respect to the head 48 and maintained at a lower potential by a source 86, Fig. 1, so that the paint moves towards the ring 70 from the edge 68 in generally radial streams, and an annular air nozzle 80 for directing a stream of air past said head 48 transversely to the said streams so as to cause at least portions of the streams to break into small particles and to assist in transporting the particles towards the article 12. The article is is maintained at earth potential and the atomized particles are carried on to the article by a combination of the air stream and the field between the apparatus 10 and the article 12. The head 48 comprises a body portion 50 and a cap 52 which is resiliently urged rearwardly against the annular flange 66 of the body portion 50 by a spring 62, the pressure of which may be adjusted. When the pressure of paint in the chamber 56 becomes sufficiently high it overcomes the force of the spring 62 and pushes the cap 52 outwardly slightly so that the paint flows to the edge 68. If desired the cap may be held in fixed spaced relation with respect to the body 50. The trigger 30 simultaneously operates valves 32 and 34 for controlling the flow of air and paint from the tanks 16 and 14 respectively. The air stream from the nozzle 80 may be slightly convergent to modify the conventional doughnut-shaped spray pattern and other patterns may be produced by modifying the shapes of the members 48, 70 and 80.

The primary extract phase can be obtained by extracting a lube oil base stock such as a vacuum distillate or residue with furfural or phenol. The colour of the resinous product can be improved by hydrogenation of the resinous product or of the secondary extract prior to the extraction with propane. The resinous product can be used for extending and plasticizing epoxy resin, polyurethanes or vinyl polymers.

Abstract: 1366185 Supply circuits for electron beam apparatus G B SOKOLOV and G F ZABORONOK 17 Oct 1972 47797/72 Heading H2H Electron beam apparatus for heat treating an article 3 comprises a vacuum chamber 1, an electron beam gun 2 including a cathode 4 and an accelerating electrode 8, a high voltage power supply 10 and a resistor 11 for limiting the discharge current between the cathode and the the accelerating electrode. The cathode 4 comprises a focusing electrode 5 and a tungsten coil electron emitter 6 connected via a conductive hollow rod 7 and an insulated lead 14 to a transformer 13. During normal operation of the apparatus, which may be used for welding, only a small leakage current flows through the high value resistor 11 so that power losses are small. In the event of a discharge occurring between the cathode 4 and the accelerating electrode 8, for example due to gas emitted by the heated article, an increased current flows through the resistor 11 from the power supply 10. A negative potential due to the voltage drop across the resistor is therefore established on the electrode 8 thereby terminating the discharge to prevent damage to the electrodes by the excessive discharge current.
