Title: Photographic flash light devices
Inventor: BEACH DAVID EASTON
IPC: G03B15/04
Filed: 1969-10-08
Abstract: 1287293 Photographic cameras EASTMAN KODAK CO 8 Oct 1969 [8 Oct 1968 11 Oct 1968] 49434/69 Heading G2A Photographic apparatus comprises a holder for receiving a percussion ignitable flash-lamp unit of the kind comprising one or more flashlamps each of which has a primer and a preenergized striker, and an actuating plunger 70 mounted for movement towards the striker on one of the strikers of a unit in the holder, to release the striker from its energized condition to strike the associated primer so as to fire the lamp. As shown, the apparatus is a camera, and the actuating plunger 70 is movable under control of a shutter release member. To make a flash exposure, a shutter release lever 50 is depressed by means of an external tab 55, and a latch 54 thereof releases an arm 64 of a shutter driver 60, so that the arm 64 can, under spring action, rotate anti-clockwise (as seen) to actuate the camera shutter (not shown). Movement of the driver 60 also causes a retaining arm 65 to release the plunger 70 which uses under spring action so that a pin 72 thereof moves through an opening (73) Fig.15 (not shown) to release the individual spring striker associated with the forwardly facing flash-lamp. During film advance, a wheel 45 is rotated anti-clockwise, thus moving a slider 80 to the right, causing a ramped end (83) thereof to contact a pin 76 and move the plunger 70 downwards. As the slider 80 moves to the right, an arm 86 connected thereto engages an ear 91 on the socket 43 (position a of Fig.17). Further movement to the right of the slider 80 rotates the socket 43, and it is held in the advanced position by a spring-loaded detent 92. This rightward movement also causes an arm 82 of the slider 80 to engage and move the shutter driver 60 clockwise to its cocked position, with the arm 64 engaging the latch 54, and the arm 65 engaging a notch 75 of the depressed plunger 70, so the slider 80 can return to its solid line position after film advance. Various forms of percussion ignitable flashlamp units suitable for use with such a camera are described in Specifications 1257845 and 1266358 with reference to Figs. 1-14 (not shown), but they form no part of the invention claimed.

Abstract: 1477412 Number senders; transistor oscillators IWASAKI TSUSHINKI KK 15 Nov 1974 [16 Nov 1973 [9 Feb 1974 (2)] 49489/74 Headings H4K and H3T In a dual frequency dialling signal generator, the frequencies to be simultaneously transmitted are determined by adjusting the inductances in two LC circuits by pairs of transistors of opposite conductivity type, each transistor pair being controlled by a single push-button contact effecting a connection between the transistor bases. In one embodiment shown the substation is powered from a line L 1 , L 2 . Prior to operation of any push-button of an array 10 transistor 33 conducts to power the transmitter T. When a button such as 11 is depressed, the bases of one transistor in each of two LC circuits 30 and 31 are directly connected together, enabling those transistors and short circuiting the base-emitter path of the transistor 33 disabling the latter to cut-off the transmitter T. A transistor 32 oscillates with a dual frequency determined by the enabled transistors in the LC circuits 30 and 31. The windings 23 and 26 are part of the corresponding transformers 21, 22, 23 and 24, 25, 26 respectively which provide the feedback paths. Diodes 40 to 43 and transistor 45 supply D.C. power to the coils 23 and 24 to prepare the same for immediate oscillation when one of the button 10 is depressed. In other embodiments, not shown, the transistor 33 is controlled by an additional transistor allowing a more stable oscillator to be provided.

Woven screen cloths are rendered hydrophilic by coating the components, before or after weaving, with (a) a solution of a substance having at least two hydrophilic groups, of which at least one has an active hydrogen atom attached to an O, N, or S atom, and (b) a synthetic resin capable of reaction with such active hydrogen, so that at least one but not all the hydrophilic groups of (a) are bonded to resin (b). Either (i) the hydrophilic compound has two or more hydrophilic groups each containing active hydrogen, e.g. OH, CO 2 H, SO 3 H, OSO 3 H, NH 2 , SH, in which case the resin is used in amount insufficient for complete reaction, or (ii) it contains at least one active hydrogen-containing group and at least one hydrophilic group not containing active hydrogen, e.g. SO 3 Na, OSO 3 Na, CO 2 Na. Compounds of type (i) include ethylene glycol, polyethylene glycol, glycerine, sorbitol, oxalic acid, succinic acid, glycolic acid, glyceric acid and aminomethanesulphonic acid; compounds of type (ii) include sodium hydroxyethyl sulphate, sodium glycerine sulphates, and sodium glycolate. The resin (b) may be polyamide, polyester, polyurethane, polyvinyl alcohol, epoxy resin, phenolic resin, melamine resin, urea resin or alkyd resin, and may be reacted with compound (a) via an intermediate condensing agent, e.g. formaldehyde, polyisocyanates and polyamines. The cloth may be of metal, e.g. bronze, or natural or synthetic fibres, e.g. polyamide. The synthetic resin may be applied simultaneously with or before the hydrophilic substance. If a condensing agent is used, this may be applied with either the resin or the hydrophilic substance, or a sequential application of resin, condensing agent and hydrophilic substance can be used. The coated cloth can be heated.

Title: Transit flask for radioactive objects
Inventor: BREBANT CHARLES
IPC: G21C13/04
Filed: 1964-12-07
Abstract: 1,055,818. Shielded containers for radio-active material. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 7, 1964 [Dec. 6, 1963], No. 49708/64. Heading B4Q. An air-tight and shielded flask for protection and transportation of radio-active objects, more particularly irradiated fuel elements, comprises and outer metal easing 2 surrounding a shielding material 1 and provided on its inside surface with at least one pocket 20 bounded by a deformable metal sheet 19 welded to the casing and filled with a fusible alloy which liquefies at a predetermined temperature, means being provided to permit the alloy to escape from the casing 2 to form an expansion volume for the shielding material 1 should a sufficient increase in the temperature inside the flask occur. In the embodiment illustrated, a cavity 3 bounded by a cylindrical jacket 4 at the centre of the flask contains a rotatable drum 5 having six chambers 6 for receiving containers 7 in which fuel elements 8 or other radio-active objects are disposed. The latter are introduced through a rotatable closure drum 9. The drum 5 is rotatable by means of a crank 14 while the drum 9 is rotatable by means of a control rod 13. A handling bar 15, a closure plug 16 and various gaskets 17 and fixing screws 18 complete the flask. A suitable alloy for filling the pockets 20 is a lead-antimony alloy containing 8% by wt. of antimony while a suitable shielding material 1 is a lead-antimony alloy containing 4% by wt. of antimony. The pockets 20 in this embodiment communicate with the outside of the casing 2 through apertures 21 which are normally closed by air-tight plugs 22 of lead-bismuth alloy and preferably also stoppers 23 of plastics material. In the event of an intense fire inside the flask, for example as a result of the violent combustion of a fuel element 8 in the drum 5, the temperature rise in the flask is such as to cause rapid melting of the lead-antimony alloy in the pockets 20. At the same time, the lead-antimony alloy of the shielding material 1 becomes malleable and exerts a thrust on the sheets 19, causing the molten alloy contained in the pockets 20 to be emptied therefrom through the apertures 21 after destruction of the plugs 22 and stoppers 23 as a result of the considerable temperature rise. The stresses on the metal casing 2 are thus rendered negligible and the internal cavity 3 is not deformed.

Filed: 1965-11-24
Abstract: 1,125,713. Gear-cutting. YUTAKA SEIMI. TSU KOGYO. 24 Nov., 1965 [27 Nov., 1964; 30 Sept., 1965 (2); 5 Oct., 1965 (2)], No. 49848/65. Heading B3K. A gear-cutting or -grinding machine for generating bevel and hypoid gears comprises a spindle carrying the workpiece 3 and a master gear 4 on an oscillatory table 1, and an arcuate gear 6 engaging the master gear 4 to cause rocking of the work about its axis and about the table axis, the arcuate gear being displaceable along its pitch circle to determine the spiral angle of each tooth surface to be cut. When the table 1 is oscillated, rack-andpinion gearing 7, 9, 9<SP>1</SP>, 11 rotates a cam 12 to determine the modifying effect of the movement of the arcuate gear 6 in its guide 13. By disengaging a clutch C, the cam is rendered inoperative. Thus, the work may be rotated through a small angle by a cam 16, Fig. 4(a), contacting the follower 6<SP>1</SP>,Fig. 1, to control the tooth space width, the cam adding an increment of motion to the arcuate gear at one end of a generating swing but maintaining the new position during the return stroke. Or a cam 17, Fig. 5(a), may be used which modifies the spiral angle on a return stroke, or a further cam may modify the spiral angle during the initial stroke. Alternatively, the cam may have two non-circular portions. In all of these embodiments, the shaft 18, Fig. 1, is driven through a double-acting ratchet device 11a,11b, Fig. 7, so that the cam rotates unidirectionally. The work is indexed by rolling the gear 4, at each end of its movement, on to a gear portion 25 or 26, Fig. 8, and moving the portion relatively to the arcuate gear. The table 1 is oscillated by a reciprocating, fluid-pressure device 36, Fig. 11, carrying a roller 38 engaging a groove in the table. In a modification, the shaft 2 is oscillated by a D.C. motor or worm gearing.

Abstract: 1527507 Selective signalling AMERICAN SCIENCE & ENG Inc 12 Dec 1975 [23 Dec 1974] 51054/75 Heading G4H Messages are sent between a central station and a plurality of remote stations over power lines using a modulated carrier, the carrier frequency being a harmonic of half the power frequency and in the range 500 Hz to 30 KHz, and the bit rate being a sub-harmonic of, or the same as, the power frequency. These choices reduce the effect of noise. To overcome the adverse effects of power factor correction capacitors, capacitor isolation networks are inserted in series or parallel therewith. The central station can address remote stations to receive back utility meter readings (the reply bit rate being selected by the central station), and can control connection and disconnection of power factor correction capacitors, distribution feeder switches and non-essential loads (e.g. electric water heaters). Power distribution system operating parameters can also be monitored. Transmission and reception of messages are synchronized with the power waveform. The central station sends the carrier unmodulated to phase-lock carrier oscillators in the remote stations, for the purposes of reception at the remote stations, but for the purposes of reception at the central station, the latter uses four parallel photo-sensitive demodulators with reference carriers separated in phase by 45 degrees, and the demodulator giving the maximum absolute amplitude after the first bit is selected.
