Abstract: 1,151,633. Purification of methacrylaldehyde. GULF RESEARCH & DEVELOPMENT CO. 18 Jan.. 1967 [18 Feb., 1966], No. 2560/67. Heading C2C. Removal of isobutyraldehyde from a mixture containing both isobutyraldehyde and methacrylaldehyde by reacting the mixture with an acidic condensing agent consisting of an aromatic or aliphatic sulphonic acid, hydrochloric acid, phosphorus pentoxide or polyphosphoric acid containing from 75 to 85% of P 2 O 5  under homogeneous liquid phase conditions at a temperature below 150 C. to yield a reaction product mixture containing a condensation product of isobutyraldehyde having a higher molecular weight and lower vapour pressure than either methacrylaldehyde or isobutyraldehyde and separating said reaction product mixture to yield methacrylaldehyde substantially free from isobutyraldehyde. The preferred condensing agents include methane sulphonic, benzenesulphonic, p-toluenesulphonic, xylene sulphonic and hydrochloric acid as well as phosphorus pentoxide and polyphosphoric acid. The process is carried out by refluxing the reactants or by mixing them at ambient temperature particularly in the case of P 2 O 5  and the reaction mixture may be diluted with water prior to isolating the methacrylaldehyde. The examples illustrate the effectiveness of a variety of condensing agents in removing the isobutyraldehyde while only slightly affecting the methacrylaldehyde present.

Title: Improvements in and relating to volume correctors applicable to air or other gas delivering machines
IPC: F04D27/02
Filed: 1923-01-30
Abstract: 215,067. British Thomson-Houston Co., Ltd., (General Electric Co.). Jan. 30, 1923. Regulating or controlling.-A volume corrector is applied to the usual governor apparatus of a centrifugal air compressor. The arrangement is shown in Fig. 2. The shaft 34 of the corrector is connected to the shaft 34a carried by the beam of the volume governor. The weight 82 is set so as to cause the compressor to deliver a certain weight of air at a selected temperature and pressure, the pointer 82a indicating the volume of the air. If the condition of the air changes, the position of the weight on the beam will be varied and the consequent movements of the beam will be communicated through the rod 75 and fluid motor 65 to the steam valve 64 of the turbine driving the compressor so as to ensure that the compressor delivers the required constant weight of air. The movements of the diaphragm do not bear a straight line relation to those required for the weight and consequently it is necessary to introduce differential mechanism between the diaphragm and the weight. In the apparatus shown, the threads of the shaft 34<a> are of varying pitch.

Title: Improvements in or relating to apparatus for comparing statistical record cards
Inventor: THOMAS ARTHUR
Filed: 1950-02-02
Abstract: 685,640. Statistical apparatus. POWERS-SAMAS ACCOUNTING MACHINES, Ltd. Jan. 18, 1951 [Feb. 2, 1950], No. 2770/50. Class 106 (i). An apparatus for comparing two perforated record cards comprises two sets of flat slidable elements 1, 2 paired to represent like card index positions and movable in opposition by impulses imparted from associated card sensing devices, each element having an abutment 9 engaged by a spring-urged axially movable pin 10, and the relative positions of the paired elements being tested to determine whether they indicate agreement or disagreement between the sensed cards. The column of elements shown has impulses imparted thereto by transmission members 13, 14, e.g. as described in Specifications 369,307 or 685,642. If a pair of elements register agreement, a detecting pin 17 on a member 15 pivoted to the element 1 is opposite a notch 19 in the element 2. If all the pins 17 in a column are in this position, a testing slide 22 having pins engaging slots 20 in the members 15 can be moved to the right by a spring 25 together with a bail 23 restored by a cam (not shown). If a column is not to be tested, a bell-crank 28 is rocked by a lever 32 to bring its hook portion 33 out of the path of the bail which can then rock freely in a slot 34 of the slide 22. Any disagreement registered in the remaining columns will cause obstruction of a slide and thus prevent full movement of the bail. This lack of movement may be used to operate machine-stopping or card-segregating mechanism, as described in Specification 369,307 or card-displacing mechanism as described in Specification 685,641.
