Patent GB-960894-A (GB)
Title: Preparation of carboxylic acids and derivatives thereof
Inventor: HEY DONALD HOLROYDE
IPC: C07C53/126
Filed: 1961-08-15
Abstract: Carboxylic acids, or derivatives thereof, containing an unsubstituted a -methylene group are prepared by the reaction of an unsaturated compound of the formula: <FORM:0960894/C1/1> wherein R1 and R2 are alkyl groups, or such groups containing indifferent substituents and R1 may also be hydrogen or an alkenyl group, with a compound containing a methyl group directly attached to a carboxylic acid group, or a derivative thereof, or a keto group under conditions which promote free radical formation. The main product of this reaction is the 1:1-adduct, but smaller quantities of the n:1 adduct are obtained by the addition of n molecules of the olefinic compound to one molecule of the methyl-group-containing compound.  Suitable starting materials are, e.g. butene-1, decene-1 and octene-1. Other unsaturated compounds which may be used include diolefines and cycloolefines. Suitable methyl-group-containing compounds are those in which the methyl group is adjacent to, e.g. CN, COCl, CO, CO2Alk, CO2Ar, CO2H and CONH2 groups. The formation of free radicals may be initiated by catalytic agents such as organic peroxides or certain azo compounds or by exposing the reactants to ultra violet light or ionizing radiations.  In preparing the 1:1 adduct the reaction is preferably carried out by adding a mixture of the unsaturated compound and free radical initiator, either alone or with a small proportion of the activated methyl compound, to a large stoichiometric excess of the latter.  In examples either di-t-butyl peroxide or dibenzoyl peroxide are used as initiators in the preparation of (1) decanoic acid from acetic acid and octene-1, (2) decanoic anhydride from acetic anhydride and octene-1, (3) ethyl decanoate from ethyl acetate and octene-1, (4) decanoic nitrile from acetonitrile and octene-1, (5) caproic acid anhydride from acetic anhydride and butene-1, (6) caproic acid from acetic acid and butene-1, and (7) nonanic anhydride from acetic anhydride and heptane-1.

Title: Measuring method and apparatus
IPC: G01J1/16
Filed: 1966-06-30
Abstract: 1,154,883. Photo-electric measurement. PRINCETON APPLIED RESEARCH CORP. June 30, 1966 [Aug.6, 1965], No.29436/66. Heading G1A. In a photo-electric system in which reference and specimen radiation beams are compared and subsequently balanced to provide a measure of the optical properties of a specimen, the balancing is provided by differently varying the polarization of the two beams relative to an analyzer: additional periodic modulation of the polarization of both beams renders the system free from the interference of stray light. In Fig. 1 plane polarized light is split into two beams by an apertured plate 44 before passage through an analyzer 52. By including a quarter-wave plate 60 in the specimen beam and periodically modulating the polarization by retarding the beam with an electro-optical device 30 fed with A.C. the intensities of the two beams on leaving the analyzer oscillate about vertical axes positioned as shown in Fig. 2. The combined reception of the two beams at a photo-multiplier generates an A.C. signal from which a D.C. signal is derived to be fed back to the electro-optical device 30 to provide a bias which shifts the vertical axes shown in Fig. 2 to balance the beams. With the inclusion of a specimen 57, whose absorption is to be measured, the system is further rebalanced by a larger feedback signal and whose difference from the previous value indicates the absorption characteristic of the specimen. The specimen is shown positioned between the lenses of a microscope at the image point of the aperture plate. The scattering of transmitted light, on the fluorescence and dichroism of specimen can also be measured Figs. 6 and 7 (not shown). The electro-optical element of Fig. 1 is a birefringent material but an element such as a Faraday cell may be used to where the plane of polarization is rotated Fig. 6 (not shown).

Abstract: 949,909. Unpacking. BAKER PERKINS HOLDINGS Ltd. July 31, 1962 [Feb. 23, 1962], No. 29448/62. Heading B8C. [Also in Division A4] Suction cups 63 are supported on a belt conveyer 55 and move at the same linear speed as loaves B in tins P on conveyer 29. On passing under suction box 54 the cups lock on to the tops of the loaves and, as the conveyers 55 and 29 diverge, the loaves are extracted from the tins. At the moment the vacuum in suction box 54 is applied to the cups a downward air blast is directed on to the ends of the loaf to loosen it. Fan 69 evacuates box 54 and supplies a further air blast at 77 which also serves to loosen the loaves in the tins. The suction box 54 rests within the conveyer 55 and is vertically adjustable with it through rotation of screw-threaded support-rod 42 by means of handle 53 and chain-andsprocket drives 51 and 45. As shown, batches of four loaves are presented to conveyer 55 in end-on position. In another form, the batches, which may be of four or five loaves, are presented in broadside-on position and each row of cups 63 has a control slide bar with holes arranged to prevent the application of suction to cups which do not engage a loaf. The position of each bar is automatically set by a movable guide whose inclination is varied in accordance with the number of loaves sensed by a feeler.

Abstract: 247,122. Gramophone Co., Ltd., (Victor Talking Machine Co.). Nov. 23, 1925. Duplicating; record traces. - Sound records with the trace in ridge form are produced by applying to a suitable record surface a fine line or layer in spirai form of a solvent of the record surface, or an unsaturated solution of the surface material, by a nozzle which is vibrated by a diaphragm in the manner of a stylus during deposition. Fig. 1 shows apparatus for recording on, a celluloid surface 17 by a fine nozzle 7 supplied with acetone, amylacetate, or other solvent of celluloid, or an unsaturated solution of celluloid, from a closed reservoir 12 to which compressed fluid may be supplied by a pipe 16. The reservoir is adjustably mounted so that the nozzle can be set quite close to the surface 17, in which position it is clamped to a rod extending from the pivoted stylus bar 5 of a recording sound-box 2. The surface 17 or the sound-box and reservoir are traversed during recording, and the deposited line or layer of solvent causes the surface at that part to swell up and leave after drying a uniform adhering ridge following the lateral vibrations caused by the diaphragm. This produces a negative master record from which an electrotype can be made and used for producing dies for stamping commercial records.
