Title: Improvements relating to panoramic objectives
Inventor: ALBERT BOUWERS
IPC: G01S11/02
Filed: 1961-05-18
Abstract: 914,389. Panoramic objectives; photographic cameras. OPTISCHE INDUSTRIE DE OUDE DELFT N.V. May 18, 1961 [May 24, 1960], No. 18169/61. Classes 97 (1) and 98 (1). In a panoramic objective having a concentric lens system with spherical surfaces and a lens with a concave-form surface between the system and the image surface, there is provided between the system and the lens another lens which has substantially cylindrical surfaces whose coinciding axes of revolution pass through the centre of the concentric lens system. As shown, the latter consists of a central spherical core 1 cemented to a spherical ring 2 which is separated by an air gap from a further spherical ring 3, the rings and core having a common centre at M. Between this system and a lens 5, the outer cylindrical surface of which acts as a support for a film during its passage between a supply and a take-up spool while the inner concave-toric surface corrects for field curvature of the concentric system, is disposed a lens 12 having substantially cylindrical surfaces with a single axis of revolution 6 passing through M. Lens 12 reduces asymmetry errors in the objective. Optical data are given for one example of the objective shown. Specification 809,055 is referred to.

Title: Process for the separation of a wax-containing mixture
Inventor: STOREY GEORGE REID
IPC: C10G73/06
Filed: 1967-04-20
Abstract: A process for separation of a wax-containing mixture by cooling the mixture in the presence of a diluent comprising a ketone, separating crystallized wax therefrom, recovering diluent from said wax and/or the non-crystallized portion, and recycling recovered diluent to the cooling step, is characterized in that at least part of the recovered diluent is contacted with an adsorbent before recycle.  The adsorbent may be clay, fuller's earth, silica gel, silicaalumina or a molecular sieve, but activated alumina is preferred; it may take the form of a moving bed, or, preferably, a fixed bed of granules 0.5-1 mm. Adsorption may be effected at ambient temperature for a residence time up to 15 mins.  Only 8-12% of the recovered diluent, which preferably comprises methyl ethyl ketone and an aromatic hydrocarbon such as toluene, need be treated.  Methyl isobutyl ketone is also mentioned.  The spent adsorbent is regenerated with superheated steam or, preferably, with 0.5-3 volumes of an alkaline liquid per volume adsorbent; calcium hydroxide, sodium carbonate, and sodium hydroxide are specified.  New adsorbent is preferably also thus treated to increase its capacity before use.  It may then be steamed and dried with hot air or nitrogen.  The process is applied to oily waxes, waxy oils, or wax mixtures.
