Title: Improvements in or relating to chlorinated products of fatty acids
IPC: C11C3/00
Filed: 1944-11-14
Abstract: A solution of a fatty acid having at least 12 carbon atoms is chlorinated with chlorine gas in the presence of light to at least 50 per cent chlorine content, and the solution exposed in a form having a large surface area to the action of an inert fluid to secure separation of the chlorinated acid in a powdery form substantially free from solvent and hydrogen chloride.  Fatty acids of high unsaturation or longer carbon chains, e.g. C16 and C18, such as linseed, soya bean, and fish oil fatty acids, are prepared.  Modified fatty acids with conjugated double bonds are also used.  Solvents specified are carbon tetrachloride, chloroform, and dichlorethane. The solution is chlorinated using sunlight or electric light as catalyst to a chlorine content preferably above 60 per cent. Concentrations of fatty acid in the solvent may be 40-50 or up to 75 per cent provided that the final viscosity does not impair free bubbling.  The chlorinated solution may be added to a large volume of boiling water, preferably with churning or mechanical agitation, the sponge-like product separating them being churned in cold water to give a powder. Precipitation may, alternatively, be effected by churning the solution with an alcohol, such as methanol or ethanol, or spraying into a warm chamber.  The products are of use in lacquers, paints, soaps, impregnating compounds, natural and syn-thetic rubbers and serve as plasticizers for more brittle chlorinated or other materials.  In examples, 10 per cent solutions in carbon tetrachloride of the following fatty acids are chlorinated followed by precipitation: stearic, oleic, linoleic, linseed, oiticica, soya, castor, coconut, and fish oil fatty acids, and pretreated or modified soya and linseed fatty acids.

Title: Improvements in Camera Systems
Inventor: PLUMMER DEXTER ROBERT
IPC: G05D3/14
Filed: 1967-05-18
Abstract: 1,170,484. Automatic speed control; cine cameras. RANK ORGANISATION Ltd. May 13, 1968 [May 18, 1967], No.23252/67. Headings G2E and G3R. In a television or motion picture camera system, a panning demand element in the form of a handwheel is geared to a tachometer generator B associated with a reversible electric motor G producing panning and a further tachometer generator G1 whose shaft is rigid with the shaft of the motor. An amplifier J receives signals from the generators B, G1, in opposition, the output of the generator G1 being attenuated by a potentiometer K which is controlled by the zoom actuating element. At maximum focal length of the zoom objective, the output voltage of generator G1 has maximum effect, and increasingly less effect at reduced focal lengths. In this manner, the panning sensitivity of the camera to a given demand remains substantially constant irrespective of the zoom setting. The potentiometer K may be used alternatively as a potential divider for varying the attenuation of the output voltages of the generators B, G1, Fig.2 (not shown). In an alternating-current system, the field windings of the tachometer generators and the motor are connected across a common A.C. source, Fig. 3 (not shown). In a mechanical transmission arrangement, two cones are oppositely mounted for rotation with their conical surfaces adjacent and parallel. The cones are coupled respectively to the panning demand hand-wheel and to the panning actuators. Power is transmitted between the cones by a part coupled to the zoom actuating mechanism and arranged to move along the length of the conical surfaces to produce variable transmission, Fig. 4 (not shown). A hydraulic transmission arrangement comprises a pump under the control of the panning demand element to operate a number of pistons whose cylinders are hydraulically arranged in parallel, the pistons being linked to move together with a member driving the pan actuators. During zooming from a small to a large equivalent focal length, a cam driven by the zoom control operates a number of switch-over valves in sequence so as to render inoperative an increasing number of the cylinders, Fig.5 (not shown).

Filed: 1965-06-02
Abstract: 1,098,248. Cine projectors. EUGEN BAUER G.m.b.H. June 2, 1965 [June 3, 1964], No.23443/65. Heading G2E. In a cine projector, separate drive elements are provided for forward and reverse running and for re-winding. Back to back freewheel couplings enable a drive motor to rotate a take-up spool, for forward running, when going in one direction of rotation and a re-wind spool when going in the opposite direction. One such freewheel coupling, between bush 35 and spring-urged member 36, allows the motor, in reverse, to transmit drive through belt 29, pulley 30 and slipping clutch 43, 44 to shaft 19 driving the re-wind spindle. For re-winding, the drive motor continues in reverse and slide 53 is moved to the left, to bring dogs 56 into engagement with cams 48 on pulley 30. This provides a rigid coupling between pulley 30 and shaft 19 thus speeding up the motion of the re-wind spindle by eliminating the slipping of clutch 43, 44. When the motor is stopped, the continued rotation of member 46, due to the inertia of the re-wind spool, throws the members 56 and 48 out of inter-engagement.
