Title: Regulating the molecular weight in the production of alpha-olefin polymers
Inventor: STAIGER GERHARD
IPC: C08F10/00
Filed: 1963-12-18
Abstract: The molecular weight of alpha-olefin polymers is regulated by polymerizing the olefin, in a hydrocarbon solvent, using a catalyst composed of a compound of a transition metal, and an organometallic compound of Groups I to III of the Periodic Table, wherein a suspension of the catalyst in a hydrocarbon solvent is treated with hydrogen, in a reservoir, at a hydrogen partial pressure of from 0.001 to 10 atmospheres before the catalyst suspension is supplied to the polymerization vessel.  The hydrogen may be mixed with an inert gas.  The alpha-olefin may be propylene, butene-1, or 4-methylpentene-1, and mixtures.  The catalyst TiCl3, or 3TiCl3.AlCl3, and diethylaluminium chloride is preferred.  The product is separated into fractions using boiling heptane.

Abstract: 1287456 Photographic apparatus FASTMAN KODAK CO 14 Oct 1969 [14 Oct 1968] 50449/69 Heading G2A [Also in Division G1] A photographic flash-light device comprises a socket for receiving a percussion-ignitable flashlamp having at least one lamp and associated primer, an actuating member 17 movable into contact with a received unit to ignite a lamp thereof, and electromagnetic means, as shown, a solenoid 10, which, when energized, effects movement of the member 17 into contact with a received unit. As shown in Fig. 1a, the electromagnetic means is connected electrically to synchronizing contacts 12 in a photographic camera 13, and the solenoid 10 moves the member 17 directly to strike the primer 19 of an inserted flash-lamp 20 when the solenoid is energized. In another embodiment Figs.1b, 1c (not shown), the actuating member (30) is moved by a spring (31) into contact with a primer (32), the solenoid (34) operating, when energized, to move a retaining member (35) and thereby release the actuating member (30) for firing action. The embodiments of Figs.1a-1c may be incorporated in an adapter (50) Fig. 1 (not shown) connectable to a camera or in a remotely located device connected to a camera by electrical conductors. The foot (53) of the adapter is insertable into a shoe (54) of the camera, but the foot may be replaced by a base suitable for insertion into a multilamp flash unit socket, the adapter being prevented from rotation. The adapter also serves as an extender. A slave type of flash device incorporating the invention is shown in Fig.2a, where a photoelectric cell 72 receives a light signal L from a camera 70, thereby energizing the solenoid 74. The pivoted actuating member 78 is associated with means 84 for rotating the socket of the device, the means being freed to rotate the socket when the member 78 is attracted towards the energized solenoid. Percussion ingnition is effected either by direct impact of the member 78 on ignition tube 82, or by the member 78 releasing a spring- biased striking member forming part of the inserted unit. The device can be used to ignite, alternatively, an electrically ignitable flash unit received in the socket, there being a pair of electrical contacts 89 connected in parallel with the solenoid 74 and connectable to suitable flashlamp contacts of a received electrical flash unit. In another embodiment Fig.2b (not shown) the slave flash device receives, at an aftenna (92), a radio signal (R) from the camera (90). In a third embodiment, Fig.2c (not shown), a sound signal controls the firing of the slave flash device. Fig.2 (not shown) illustrates a slave flash device (60) having an orientatable sensor (64), the device being capable of adaption to receive any of the embodiments of Figs.2a-c.

Abstract: 1299585 Photo-electric control of printing apparatus PENTAGON DRESDEN KAMERAUND KINOWERKE VEB 24 Oct 1970 50610/70 Heading G2A A micro-film camera has an automatic exposure-control device in which the maximum intensity value reflected by the background 2b of a subject 2a is received by a photo-electric cell 3 and used to control the illumination of a light source 19. A rotatable glass wedge 6 enables an area 5 in the subject plane which is imaged by a lens 9 in the reception surface of the photo-electric cell to follow a path 7 and to thus periodically swing over the marginal zone 2b of the subject. The output of the photo-electric cell is fed via an A. C. amplifier 15 to a peakvalue rectifier circuit 16, the time constant RC of which is large compared with the period of revolution of the wedge 6. The voltage appearing across the terminals A, B is then fed to an electronic control apparatus 18 containing two triggers with different threshold voltages to switch two relays contained in a motor circuit. The motor controls a regulating transformer which adjusts the brightness of lamps 19. Alternatively, circuit 18 contains controlled thyristors.. A basic intensity value, or the 'zero' of a black subject, is obtained once every revolution of the wedge by a cam plate 14 closing a switch 13 to short circuit the photo-electric cell. Alternatively, the basic intensity value is obtained by darkening the photo-electric cell or by switching on an auxiliary light source of constant luminous intensity.

In the form shown, the cooker and boiler parts of the stove are heated by separate zones of the fire. Combustion in the cooker zone is controlled by a thermostatically operated damper 94a in the flue 44b, 44c. Across the flue 44b is a partition with an opening which is filled by the hollow cylindrical plug 37, the top of which acts as a closure for an opening in the part 26' of the hot-plate.
