Filed: 1963-11-27
Abstract: 1,033,070. Optical apparatus. PERKINELMER CORPORATION. Nov.27, 1963 [Nov.27, 1962], No. 46899/63. Heading G2J. An accessory for an infra-red spectrophotometer enabling spectra to be obtained with a micro-sized sample, operates on the principle of attenuated total reflectance. As shown a stationary toroidal mirror M1 and plane mirror M2 receive a converging team of infra-red radiation and form a reduced image of the radiation source at the primary focal length plane of the hemicyhidrical high refractive index germanium crystal C. The collimated radiation passing through the crystal C is internally reflected adjacent sample S, refocussed at the primary focal length plane, reflected by rotatable toroidal mirror M3 and rotatable plane mirror M4 and refocussed at the entrance slit SL of the spectrophotometer. This refocussing is done at any angle of incidence between 25 degrees and 65 degrees and in order to maintain a constant path length regardless of the angle of incidence, mirror M4 and crystal C rotate through the same angle whilst mirror M3 traverses twice that angle. This may be done by mounting the crystal C on a rotatable shaft A, Fig. 2, (not shown) carrying mirror M4 through an arm B and carrying a 99 tooth gear 13 meshing with a 70 tooth gear 16 on a parallel shaft 17 carrying a 99 tooth gear 18 meshing with a 70 tooth gear 14 connected through an arm A<SP>1</SP> with mirror M3.

Title: Fuel injector for internal combustion engines
IPC: F02M61/10
Filed: 1975-11-17
Abstract: 1488985 Fuel injection valves for IC engines KLOCKNER-HUMBOLDT-DEUTZ AG 17 Nov 1975 [9 Jan 1975] 47293/75 Heading F1B A fuel injector 1 has a needle 2 with a conical head 3 in a conical seat 5 moved upwardly by pressurized fuel supplied by a duct 6 against a spring 4 and fuel pressure in a buffer chamber 9 to effect injection. The buffer chamber 9 is pressurized through inlet duct 10 and relieved through outlet duct 11 by fuel passing through throttling restrictions 13, 14 respectively under control of a change-over valve 15 whose spring is selected to open inlet duct 10 when the injection pressure is reached. The throttling restriction 13 ensures slow build-up of pressure in the buffer chamber 9 allowing the needle 2 to rise under the influence of the injection pressure in the duct 6. After injection when this pressure drops the change-over valve 15 closes inlet duct 10 and opens outlet duct 11. Initially the needle 2 is forced downwards by the pressure in the buffer chamber 9, which then drops to zero as the fuel escapes through throttling orifice 14. The buffer chamber may be a separate chamber not containing the spring 4, and may contain an hydraulic piston acting on the valve needle end (not shown). In an alternative, the change-over valve has one flat seat and one conical seat. By selection of spring pressure in the change-over valve, the arrangement allows needle opening and closing pressures to be equalized. As the buffer chamber pressure is always reduced to zero after injection, variations of needle closing pressure with engine speed and load can be reduced.

Title: Production of ketones
IPC: C07C45/54
Filed: 1965-11-11
Abstract: A process for the production of ketones comprises contacting an aldehyde of the formula <FORM:1049990/C2/1> wherein each of the R1 and R2 groups is C1- 10 alkyl, and R3 is H or C1- 10 alkyl, in the vapour phase with water in a molar ratio of at least 5 mols. of water to one mol. of aldehyde, in the presence of a catalyst, which is either phosphoric acid supported on a solid carrier or is a solid acidic, silica-containing catalyst composite, at a temperature between 200-600 DEG  C. The reaction is a re-arrangement represented by the equation <FORM:1049990/C2/2> The phosphoric acid catalyst is made suitably by soaking an inert support, e.g. ceramic Berl saddles or pellets of diatomaceous earth, pumice or silica gel, in an aqueous solution of the acid. The silica-type catalysts comprise an acidic metal oxide and the remainder is essentially silica.  Suitable acidic metal oxides are alumina, zirconia, titania, magnesia and boria.  The catalyst may be used in a fixed or fluidized bed.  The reaction is preferably conducted between 375-500 DEG  C. with a contact time of between 0.1 and 10.0 seconds. The mole ratio of water : aldehyde is preferably 10-21 : 1, but may be as high as 40 : 1. Superatmospheric pressure may be used.  The Figure (not shown), shows a suitable apparatus for performing the reaction.  The catalyst may be regenerated in conventional manner by contact with an oxygen-containing gas and an inert diluent, e.g. steam, at a sufficient temperature to burn off the carbonaceous deposits.  The products are collected by, e.g. condensation or vapour-phase solvent-extraction, followed by condensation and distillation
