Filed: 1964-05-07
Abstract: Paraffins are obtained by acid hydrolysis of organo-aluminium talomers (see Division C2) of formulae [R(CH2-CH2)a]2AlCl and R(CH2-CH2)aAlCl2, wherein R is an alkyl radical having 1 to 10 carbon atoms and a is 1 to 15.ALSO:Impure aluminium trichloride, e.g. of 80 to 99% purity and contaminated with silicon tetrachloride, titanium tetrachloride, ferric chloride and non-volatile material, may be reacted with trialkyl aluminium to prepare the mixture of alkyl aluminium chlorides forming the starting material for the telomerization reaction with ethylene if the reaction mixture or reaction product is saturated with ethylene prior to the addition of the telomerization catalyst titanium tetrachloride.  A mixture, e.g. equimolecular, of trialkyl aluminium having up to 10 carbon atoms per alkyl group and the impure aluminium chloride is reacted at - 10 to 100 p.s.i.g. at 40-150 DEG  C. for 5 to 360 minutes, the reaction product, filtered if necessary, is preferably dispersed in an inert hydrocarbon solvent under an inert gas and ethylene passed at - 10 to 100 p.s.i.g. through the dispersion at 40-150 DEG  C. for 1 to 60 minutes.  To the ethylene-saturated mixture titanium tetrachloride in a mole ratio of Ti ratio Al of 1 ratio 500 to 1 ratio 50 is added, and during or after addition, ethylene is passed at e.g. 0.3 to 60 mols per hour per mol of alkyl aluminium chloride for e.g. 30 to 360 minutes, the temperature of the reaction mixture being 40-150 DEG  C. Organo-aluminium telomers of formulae [R(CH2-CH2)a]2AlCl and R(CH2-CH2)aAlCl2 are obtained, where R is an alkyl radical having 1-10 carbon atoms and a is 1 to 15. Alcohols are prepared from these by oxidation at 30-100 DEG  C. at a pressure between atmospheric and 500 p.s.i.g. for 15 to 60 minutes using one mol of oxygen per two mols of alkyl groups and the aluminium alkoxy chloride formed is hydrolysed using e.g. dilute HCl.

Aug. 15, 1924. Sheet-cutting machines. - Contin- @ous rotary machines for making grained inlaid floor coverings are fitted with cutting dies adapted to oscillate axially so that the pattern elements after being cut from the web are turned so that when assembled on the backing they lie with the grain at an angle with the line of direction of the floor cloth being made. Webs of plastic material are brought to inlaying machines by conveyers. Each web comprises several ribbons and a separate shoot is provided for each ribbon. The cutter bloch 35 are mounted on a cylinder 33 in gear with a cylinder 34 carrying the oscillating dies. The ribbons are fed intermittently by mechanism operated by cams on a shaft 27. The dies are mounted radially in holes in the cylinder 34 and are actuated by stationary internal cams. As each die, Fig. 4, with its tessera leaves the cutter block 35, the tappet 75 rides on to a projection on each of its two cams and the cup 73 is pressed against a spring 74, to allow inward movement of a pin 72. A cam 76 on the spindle 37 then meets another stationary @am and the die is turned through the required angle. The tappet 75 is then released by its cam, the spring 74 expands, and the pin 72 is forced into another notch, securing the die. The rod 61 is then forced upwards by a cam and the pattern element is ejected on to the conveyer F. Further cam action results in the die being returned to its former position.

Title: Improvements relating to steering and stabilizing means for motor vehicles
IPC: B22D39/06
Filed: 1956-06-22
Abstract: 802,937. Controlling and steering vehicles DAIMLER-BENZ, A. G. June 22, 1956 [June 24, 1955], No. 19423/56. Class 79(5) [Also in Group XXXII] In a motor vehicle having servo-operated steering and stabilizing means both the steering and stabilizing servomotors are operated by the same pressure medium and are controlled from the steering wheel 46 so as to be co-ordinated with each other. As shown the invention is applied to wheel suspension comprising upper and lower links 12, 13 supporting wheel carriers, the carriers 10, 11 for the front wheels being steerably controlled from the steering wheel 46 acting on a three-part track rod 41, 42, 43 connected to steering arms 44, 45. The lower links 12 are mounted on auxiliary frames 22, 23 resiliently connected to the vehicle frame (not shown), and pivotal movements of the lower links act on torsion rods 24, 25, 26, 27, the rods 24, 26 being connected to an arm 28 and the rods 25, 27 to an arm 29. The arms 28, 29, are rotated in unison by a rod 31 carrying a piston 33 within a cylinder 32 resiliently mounted on the vehicle, rotation of the arms 28, 29 serving to cant the vehicle body. The cylinder 32 is connected by pipes 34, 35 through a valve 34a to a valve 36 comprising a piston 50 connected by a link 49 to the drop arm 48 of a steering gear 47 controlled by the wheel 46. The valve 36 is connected by pipes 38, 39 and a double pump 37 to a liquid reservoir 40, the pump serving to pressurize the pipe 38 and exhaust the pipe 39. The body of the valve 36 comprises two ports, one port 56 being connected to the pipe 34 and through a hollow section of the track rod part 42 to a port 57 on one side of a piston 52 in a cylinder 54, and the other port 59 being connected to the pipe 35 and through a pipe 58 within the track part 42 to a port 60 on the other side of the piston. With the piston 50 in its neutral position shown in Fig. 1 the ports 56, 59 are closed and movement of the steering wheel 46 for turning to the right or left causes one of the ports to be connected to the pipe 38 and the other port to the pipe 39, whereby the pistons 33, 52 are moved in their cylinders to give a right or left hand steering turn and the body is tilted to compensate for centrifugal action. The valve 34a is provided to enable the lower portions of the pipe 34, 35 to be interconnected to permit adjustment of the suspension. In another embodiment, Fig. 2, the steering drop arm 48 is connected to a control valve 36a secured to the middle track rod 54a having a piston rod 42a pivoted to the vehicle frame. The stabilizing cylinder 32 is connected to a valve 64 having a piston element 65 connected to an arm 61. The arm 61 is mounted on the steering wheel shaft 46a by means of a clamp 62 with the interposition of an exchangeable friction sleeve 63. In operation the arm 61 is moved in advance of the steering gear due to backlash in the latter, whereby the vehicle body is tilted before the vehicle takes the steering turn.

Title: An improved method for superposing photographic images
IPC: G02B27/14
Filed: 1937-07-14
Abstract: 500,728. Producing composite photographs ; colour photography. PLANSKOY, L. July 14, 1937, No. 19546. Convention date, July 15, 1936. [Class 98 (ii)] Apparatus for taking a number of part images which, after development, are placed in the same position as in taking and accurately projected through the same optical systems so that they are superimposed in register, comprises a beam splitter 4, a collimator 2 and lenses 5, 7. In the making of the composite images, an image of a subject in front of a monochromatic background is formed at A and is projected through the optical system onto light sensitive films 6, 8 of the non-contractile type. The beam passing through the lens 5 influences the sensitive film 6 and after development gives a negative 6a of the subject on a dense background. The deflected beam passes through a colour filter and gives a latent image on the film 8 which, if developed would yield a negative of the subject on a transparent background. The monochromatic background may be replaced by a backing, e.g. of chloramine black, which reflects infra red, or may be illuminated with polarized light. The negative 6a after development is projected back through the optical system and a mirror is placed at the point A. The reflected ray then effects the undeveloped image on the negative 8, which then, upon development, yields a mask 8a of the subject. In forming the composite image, the films 6a, 8a, Fig. 3, are placed in their respective positions, and a negative 11 of the background is inserted at the point A. The films 6a, 8a are then illuminated by lamps 10, 12 and the composite image formed on the film 14. In a modified optical system, the reflecting beam splitter is placed in the path of converging rays from the objective lens. In the application to colour photography, the part images are projected through filters onto the sensitive surfaces. After development, these images are projected successively through the same optical systems but in the reverse direction, in order to print copies by the known subtractive or additive processes. Composite images in colours are obtained in the same manner using a number of invariable optical systems greater by one than the number of colour filters. Several distinct schemes or subjects may be superimposed on the background for the formation of a composite image.

[Class 100 (ii).] Cylinder machines; tripping-arrangements.-In a travelling cylinder machine of the kind in which the cylinder 34 and the bed 1 are reciprocated in opposite directions, and the bed is lowered automatically on its return, the bed 1 is mounted so as to move horizontally with a reciprocating carrier 2 which moves in a constant plane and is provided with racks 3 for driving the impression cylinder, and with racks 5 for reciprocating the carriage of the impression cylinder through the intervention of gears 51 mounted in a fixed frame. The bed 1 is moved vertically relatively to the carrier 2 by supporting the bed 1 on rails 6 carried by rollers 7 which can slide on tracks 8 which are raised and lowered automatically by eccentrics 14 which are interconnected by link-mechanism for simultaneous operation by means of an oscillating arm 17 which is operated by a cam 28 and lever 27, from the shaft of the crank 31 which reciprocates the carrier 2. Motion is communicated from the arm 17 to a disc 19 secured to the shaft 9 of the eccentrics 14 by means of a spring-plunger 18 which normally projects from the disc 19 and is received in an aperture in the arm 17. The plunger 19 can be withdrawn by means of a wedge 251 on a lever 25 which is operated by a cam on a lever 23 which can be set to cause the plunger to be withdrawn while the carrier 2 reciprocates so as to enable the bed to be depressed while the cylinder reciprocates, and also to depress the bed when the machine is stopped. In a further position of the lever 23 the plunger 19 remains permanently in engagement with its recess and the bed is lowered only when the cylinder makes its non-printing return stroke.

Title: Improvements in mechanical time fuses for projectiles
IPC: F42C9/04
Filed: 1931-07-08
Abstract: 370,766. Projectile fuzes. SOC. ANON. ARTURO JUNGHANS FABRICA D'OROLOGERIA, Venice, Italy. July 8, 1931, No. 19684. Convention date, Aug. 15, 1930. [Class 9 (i).] Relates to clockwork time fuzes of the kind in which the clockwork is released by an inertia bolt at the start, and after the predetermined time releases a centrifugal member which in turn releases a centrifugal striker. According to the invention, an additional safety device is provided which is operated by the clockwork and releases the centrifugal striker after the projectile has travelled a certain distance. The inertia bolt 1, Fig. 2, on setting back at the start, releases a pin k<2> on the spindle k of a lever k<1> which then bears by centrifugal force against the periphery of the time disc m, Fig. 3, until at the appointed time it enters the notch m<1> in the disc. This causes the spindle k to release a centrifugal lever i<1>, the spindle i of which in turn releases a second centrifugal lever h, Fig. 5, which releases a radially-movable centrifugal striker g, firing the fuze. The additional safety is provided by an eccentric o<l>, which locks the striker until it is driven round sufficiently by the clockwork. The drive from the clockwork is transmitted to a pinion on the spindle o of the eccentric, which pinion is not provided with a full ring of teeth, so that when the eccentric unlocks the striker the pinion goes out of mesh and the eccentric is held in the unlocking position by centrifugal force. The centrifugal striker, when locked, is restrained from movement by a spring washer p.
