Title: Oxygen-containing tricyclodecane derivatives
IPC: C07D303/48
Filed: 1964-11-10
Abstract: New compounds of formula <FORM:1015940/C2/1> where R1, R2 are H or CH3, and X is: (1) <FORM:1015940/C2/2> , where R is H or C1- 4 alkyl; (2) -CHO; or (3) -CH = CHCOR1, where R1 is C1- 5 alkyl, useful in perfumery, are obtained from cyclodiene dimers and their keto derivatives of the above formula wherein X is =O. Thus, dicyclopentadiene is converted in known manner to the corresponding mono-olefinic alcohol, hexahydro - exo - 4,7 - methanoinden - exo-5-ol which is hydrogenated and oxidized to octahydro-exo-4,7-methanoinden - 5 - one.  This ketone can be converted to a glycidate by reaction with an alkyl a -chloracetate in presence of alkali metal hydride or alkoxide, hydrolysed to the glycidic acid, and decarboxylated to the aldehyde.  This gives various unsaturated ketones by reaction, e.g., with acetone or methyl ethyl ketone, and saturated ketones on subsequent hydrogenation. Examples describe the preparation of octahydro-exo-4,7-methanoinden - 5 - ethyl glycidate, the corresponding methanoinden - 5 - al, and the corresponding buten- and penten-1-one-3.ALSO:Compounds of formula <FORM:1015940/A5-A6/1> where R1, R2 are H or CH3 and X is:  (1) O-CH-COOR, where R is H or C1-4 alkyl;  (2) -CHO; or (3) -CH=CHCOR1, where R1 is C1-5 alkyl, are used in perfumes, soaps, cosmetics, and baby lotions. Examples are given of perfumes containing octakydroexo-4, 7-methanoinden-5-ethyl glycidate, and the corresponding 5-al, -buten-1-one 3, and penten-1-one-3-derivatives.

Title: An illumination intensity indicator
IPC: G01J1/44
Filed: 1967-10-16
Abstract: 1,142,536. Light intensity measurement. P. GOSSEN& CO. G.m.b.H. Oct. 16, 1967 [June 6, 1967], No. 46973/67. Heading G1A. [Also in Division G2] A light intensity measuring device in which adjustment of a light attenuation device varies the amount of light falling on a photo-sensitive element, has two indicator lamps one of which flashes on and off at a rate dependent on the size of the displacement of the light attenuation device from its correct setting. In the exposure meter shown a photo-resistor 1 forms a potential divider with a resistor 3 or a resistor 4 according to the setting of a range switch 6. In operation a diaphragm 19 is adjusted varying the amount of light falling on the photo-resistor 1 until the correct setting is reached. At this correct setting both of a pair of transistor 7 and 7' of oppositely conductive types will conduct causing both of a pair of lamps 16 and 16' to glow continuously. If for example the diaphragm initially is set allow too much light to fall on the photo-resistor, the resistance of the latter is low and the transistor 7' is near cut-off. A capacitor 10' charges slowly until a unijunction transistor 12' breaks down rapidly discharging the capacitor. This charging and discharging continues in repetitive manner. A transistor 14' conductive during the charging periods causes a lamp 16' to glow during these periods. As the diaphragm is adjusted towards it correct setting the transistor 7' is more conductive and the lamp 16' flashes more frequently. At the correct setting the resistance of the transistor 7' is so low that the unijunction transistor 12' cannot be switched to conduction and the lamp 16' burns continuously. If the diaphragm is set to pass too little light the lamp 16' glows continuously and the lamp 16 flashes in a manner similar to the above. Resistors 18 and 18' are provided to limit the lowest flashing frequency. A modification employing two photoresistors one for each half of the circuit are provided. They are selected alternately by a switch and diodes 8 and 8' are not required.

Abstract: 1,148,670. Winding webs. COMPAGNIE GENERALE D'ELECTRICITE. 24 Oct., 1966 [25 Oct., 1965; 29 April, 1966], No. 47741/66. Heading B6B. [Also in Division H1] In a web winching machine, and in particular a capacitor winding machine the web is transferred from a supply roll to a take-up spindle by a transfer device. This transfer device comprises at least two rollers, one of which is supported by an arm pivoted at the source of rotation of the other roller. In Fig. 6 a supply roll 11 is mounted for rotation on arm 14 pivoted at 32 to the machine frame 1. An adjustable counterbalance 26 balances not only the supply roll 11 but a series of transfer rollers 22, 18 and 30. Roller 18 is mounted at the extremity of the arm 14 for rotation about an axis 19, and rollers 22 and 30 are rotatably mounted on respective arms 21 and 36 pivoted about the same axis 19. A counter balance (spring or counterweight), shown diagrammatically at 27, balances the arm 36 in any position, so that the roller 30, which contacts roller 18, contacts the supply roll 11 with a pressure resulting only from the tension in the web 17. The arm 21 has a return means, for example a balance weight, which loads the roller 22, which contacts roller 18, against the take-up spindle B when in the winding position shown in broken lines. A locking device comprising a magnet 2 on the machine frame 1 and a magnet 3 on the arm 14, retains the arm 14 in the winding position. Transverse guiding of the web 17 is achieved with flanges (40) on the roller 30 (Fig. 7), or guides as shown in (Figs. 3 and 4), axial movement of the supply roll 11 being allowed. The supply roll is braked for tensioning the web by spiral springs (50, 51, Fig. 7) placed coaxially with the shaft 12. The two-part spindle B (Fig. 9) is mounted between a pair of arms 42, pivoted at 47 which enables the web 17 to be attached to spindle prior to moving it to the winding position shown at b<SP>1</SP>. The spindle is driven by a belt and pulley arrangement and a motor 43, and its slot can be correctly orientated for attachment of the web by a crank (61, Fig. 8). A second web 117 may be wound at the same time, its supply roll 111 rotating about a shaft 112 fixed to the machine frame 1. The transfer device comprising rollers 122, 118 and 130 is mounted on a shaft 119 fixed to the machine frame 1.

Abstract: 1365947 Rotary heat treatment furnaces S A ELIOT 14 Oct 1971 [22 Oct 1970] 47931/71 Heading F4B A rotary furnace for the continuous heating of forge bars 112 comprisse a chain and sprocket drive for the drum 10 which is mounted on a vibratory underframe 16 and a burner 50 in a fixed compartment 49 at the discharge end of the furnace. At the charging end of the furnace is a preheating chamber 70 inclined at an angle of 25-45 degrees to the axis of the drum 10 and heated by the hot gases therefrom. The chamber 70 may also have a burner for use during the heating up period. Forge bars 112 collecting on the floor 104 of the chamber 70 against a stop 110 are pushed one at a time over said stop by the plunger 81 of a pneumatic motor 80 on to a curved stop 114. Another pneumatic plunger (83, Fig. 5) pushes them into the furnace drum. At the discharge end, the bars fall singly on to a counterweighted hinged door 56 where their temperature is recorded by a sensing device 61. The bar temperature is used to produce a signal controlling the gas burner and the cycle period. The weight of a bar opens the door to the position 56A while its temperature is measured, whereupon pneumatic motor 53 swings it to position 56B allowing said bar to fall on to a receiving table. During heating the drum 10 is rotated to roll the bars over and discharge is by vibration of the underframe 16. The preheating chamber may be a further rotary drum disposed axially of the drum 10 and it may have a plurality of passageways for the bars. The control of operations in timed sequence is by a circuit (Fig. 9) including timers, contacts and relays and incorporating lights (LT1-LT7) indicating commencement of each operation and an audible signal (HR) which sounds if no bar falls from the door 56 within a given time.
