Title: An ultra-violet irradiation apparatus
IPC: H05B41/04
Filed: 1959-02-26
Abstract: 896,356. Supply systems for discharge lamps. QUARZLAMPEN G.m.b.H. Feb. 26, 1959 [March 1, 1958], No. 6697/59. Drawings to Specification. Class 38 (4). A discharge lamp used as an ultra-violet radiator is overloaded for short periods in order to increase its radiation without an increase in the size of the lamp. The overload is caused by temporarily reducing the series impedance or discharging a capacitor into the lamp circuit, either method being controlled by a timing switch. In the Specification, it is stated that a lamp rated at 3000 ÁW/cm.<SP>2</SP> in the UV-B range may be flashed to give a radiation of 6000-15000 ÁW/cm<SP>2</SP> for 0.5 to 10 seconds. To avoid overheating the lamp, the spacing time of the flashes may be about twice the flashing time. The lamp may be constructed so that the tube diameter and electrode distance are designed for the average load, but the lead-in conductors and electrodes are dimensioned according to the overload. The electrodes may consist of tungsten with 5% thorium oxide added.

Abstract: 984,129. Spring clips. A. RAYMOND. Feb. 19, 1963 [Feb. 26, 1962], No. 6699/63. Heading E2B. A substantially U shaped resilient fastener is formed from a single strip of metal and has a web 11 and two limbs 10 and 10a, the free end of the limb 10 being bent so as to extend forwardly then rearwardly of the U and away from the other limb, the limb 10a having means 16 for engaging a member 1 embraced by the two limbs and a lug 9 being sheared from the limb 10 and bent rearwardly of the U and away from the limb 10a. The fastener is intended for securing a beading 2 to a member 1. In the construction shown the limb 10a has its upper portion bent towards the member 1 so that its end portion engages the limb. In a modification however the limb 10a is substantially straight and instead of having a tongue 8 for engaging a flange 3a of the member 1 as shown, it has a prong 19 sheared from each free edge of the limb to engage one surface of a member 1 which is in the form of a panel. In a modification of this construction the web 11 is elongated and the limb has four claws, two of which extend towards the other limb and two away from it, this limb being intended to be inserted between the panel and a covering of the panel.

Title: A method for securing the bridges to the lenses in rimless spectacles
IPC: G02C1/02
Filed: 1946-03-05
Abstract: 623,008. Rimless spectacles. SOC. DES LUNETIERS (Eparvier, Ottolini, Cottet & Cie.). March 5, 1946, No. 6891. Convention date, March 23, 1945. [Class 97 (i)] [Also in Group XXII] Metal bridges are connected to rimless spectacles by drilling one or several holes through each lens near the edge thereof adjacent the bridge, filling each hole with a piece of alloy whose ends are flush with the faces of the lens and then electrically welding the ends of said filling pieces to the bridge metal portions that clamp the bridge to the lens. Thus, in one example, a piece of alloy 2 is inserted in a hole drilled in the edge of each lens 3 and the lens is positioned between the jaws 1, Fig. 1, of the clamp of the bridge 4, Fig. 3. The clamp rests on a support 5 which is connected to one terminal of the secondary winding of a transformer, the other terminal thereof being connected to tongs (not shown) between the carbon pencils of which the jaws 1 are held; a movable member 6 serves to press the lens edge against the base of the clamp. The circuit through the transformer primary is then closed with the result that the piece of alloy softens. Thereafter, the current is switched off and the tongs are retained in position until the alloy has cooled. The clamp may have only one jaw, the second jaw being replaced by a suitably shaped disc to which the alloy will adhere; also, a spring may be interposed between the clamp and lens edge.

Title: Safe load indicator for jib cranes
IPC: B66C23/90
Filed: 1976-02-25
Abstract: 1522442 Crane safety devices WEIGHLOAD Ltd 17 Feb 1977 [25 Feb 1976] 7446/76 Heading B8H In an overload warning device of the type described in Specifications 993,594 and 1,119,485 for a luffing crane with a telescopic jig, allowance for jib length is made by automatically positioning a follower 43 over the one of a bank of cams 44 appropriate to the prevailing jib length. A pointer 18 actuated by a pressure gauge connected to a hydrostatic load cell on the jib indicates the load suspended on the jib. A pointer 19 indicates the maximum safe load for the prevailing jib angle and length. If the pointer 18 nears pointer 19, a warning light is actuated, while closer approach sounds a warning bell. A miniature slave jib 26 secured to a shaft 27 is connected by Bowden cables 30 to the crane jib to maintain the same angle to the vertical as the latter. A flexible drive cable 34 which is rotated in response to telescopic movement of the jib extension is coupled by gears 35 to a leadscrew 31 on the slave jib 26 so that a nut 37 on the leadscrew is positioned according to the jib length. The nut slidingly engages a bar 38 connecting carriages 39, 40 slidable along rails 41, 42 respectively. Carriage 39 carries the cam follower 43 which moves along one of the cams 44 as the jib angle and/or length changes, the cams being secured to a shaft 45 carrying a sector gear 46 meshing a gear 47 on the pointer 19. A contact 55 on the nut 37 co-operates with contacts (Ba-Bh) (Fig. 4, not shown) on the slave jib forming part of a motor control circuit so that on a change of jib length a motor M, raises the cams 44 clear of the follower 43, a motor M 2  moves the follower transversely to align it with the appropriate cam, and the motor M 1  is de-energized to allow the cams to descend until the appropriate cam contacts the follower.

[Class 120 (ii)] The screw 9 regulating the movement of the disc 1 of the speed-regulating arrangements of the parent Specification is driven from the ratchet mechanism of the frame through bevel gearing, the shaft 2041 of the driven gear 204 carrying the screw being turnable about the shaft 2031 driving wheel 203 while the mechanism for returning the screw 105 and associated parts, which regulate the movements of the disc 1 according to the layer speed, to their initial positions at the descent of the ring rail is actuated by gearing connected to the wheel 203. As shown the screw 9 is carried in a frame 2042 oscillatable on the shaft 2031 carrying the driving gear 203 which is fast with a sprocket 218 geared to a sprocket 220 carrying a bevel gear 212 meshing with. a gear 211 on the screw 105 mounted in a sleeve 104 in a frame 209 oscillated from the mechanism giving the rising and falling movements to the ring rail. The screw 17, carrying the member 19 engaging the disc 1, passes through the screw 105 and has a trunnion 170 carrying a hinged detent 215 that can be engaged with one of a series of slots 214 on a stop member 107 and in one of a series of grooves in'a sleeve 216 connected to the sleeve 104 so that the stop is adjustable within the sleeve 104 without moving the returning mechanism out of its position. As spinning proceeds the screw 105 is rotated and moves in the sleeve 104 until it meets the adjustable stop 107 when its movement is transmitted to the screw 17 with the result that the amplitude of the layer speed is reduced to the end of the spinning. The sleeve 216 has grooves engaged by a ball catch 217 which prevents the sleeve being involuntarily turned by friction between the screw 105 and sleeve 104. Specification 411,066 is referred to.

Title: Improvements in or relating to commodity wrappers and the use thereof
IPC: B65D65/42
Filed: 1951-04-06
Abstract: A commodity, e.g. cheese or meats, non-blocking wrapper (see Group VIII) comprises a durable flexible base sheet, e.g. regenerated cellulose, a continuous surface layer of pressure-sensitive adhesive thereon, and a coating of particulate material, e.g. stearic acid, gelatine, agar-agar, gelatinized starch, sodium carboxymethyl cellulose or methyl cellulose, gum tragacanth or karaya, or polyvinyl alcohol, dispersed over the adhesive, which material possesses the properties of swelling by the action of the oil and/or moisture contained in the commodity to provide an intermediate layer on contacting the commodity and being unaffected by the pressure-sensitive adhesive before or after formation of the package seal.  The commodity is wrapped with the coated side of the wrapper inwards and subjected to pressure, and if necessary heat, to seal the commodity in the wrapper, and expel trapped air from the package through passages formed by the particulate coating.  The particles soften and swell to form a continuous film intimately contacting the commodity and preventing mould growth.
