Title: Process for the preparation of cyclopropanecarboxylic acids of trans-form
IPC: C07C61/37
Filed: 1959-05-26
Abstract: An ester of a cis-cyclopropane carboxylic acid is converted to the corresponding trans-ester by means of an alkali metal alcoholate such as a t-amylate, t-butylate or dimethybenzylate.  A solvent is preferably used, e.g. an aromatic hydrocarbon or an alcohol.  The reaction starts at room temperature and may be completed by heating, e.g. at reflux.  The product may be isolated by evaporation of the organic layer formed after the addition of water to the reaction products ; some trans-acid is obtainable from the aqeous layer.  The esters may be hydrolysed to the trans acids.  In examples the cis forms of methyl 2-phenyl-cyclopropanecarboxylate, methyl 2-phenoxy-cyclopropanecarboxylate and methyl chrysanthemate are converted to the trans forms which are hydrolysed to the corresponding acids.  In example 1, methyl cis-2-phenylcyclopropanecarboxylate is prepared by the action of diazomethane on the acid in ethereal solution.

Abstract: 711.469. Automatic control systems. ELECTROACUSTIC GES. July 19, 1950 [July 19, 1949; March 30, 1950; May 12, 1950; June 12, 1950], No. 18052/50. Class 38(4) [Also in Group XXXVIII] In an underwater pulse-echo ranging system for indicating echoes from reflecting bodies within a selectable range increment (see Group XXXVIII) the range increment is displayed on the high-speed time base of a cathode-ray tube and the time interval between the transmission of a pulse and initiation of the time base is automatically controlled by the echo pulse so that the echo is displayed at a predetermined position on the time base. The transmitter is triggered periodically by a switch operated by a rotating cam disc, Fig. 3 (not shown), and the time base is initiated by the closure of a second switch whose angularly position around the periphery of the cam disc is controlled by the angular position of a disc 25 bearing two semi-circular contacts 23, 24 over which an arm 21 rotates synchronously with the cam disc. Contacts 23, 24 are connected to H.T. supplies and also via condensers 32, 33 to the coils of relays 30, 31 whose associated contacts 28, 29 are in series with the two field windings of a reversible D.C. motor 27 which drives disc 25. A received sonic echo pulse is converted into a corresponding electrical pulse by an electroaccoustic transducer 16 and applied to trigger a thyratron 17 whose anode is connected to the rotating arm 21. If an echo is received when arm 21 is contacting 23, condenser 32 is discharged and relay 30 operates causing disc 25 to rotate in one direction and similarly the disc is rotated in the opposite direction when arm 21 is contacting 24 so that the disc assumes an equilibrium condition such that arm 21 is intermediate between contacts 23, 24 at the time of echo reception, the angular position of the disc then indicating 'the range of the echo.

Title: Improvements in or relating to reflex reflectors suitable for road or advertising markers
IPC: G09F13/16
Filed: 1943-11-08
Abstract: 586,594. Coated fabrics. MINNESOTA MINING & MANUFACTURING CO. Nov. 8, 1943, No. 18528. Convention date, Jan. 23. [Class 140] [Also in Groups XVIII and XX] In a reflex reflector of the kind comprising a layer of small transparent spheres 14, Fig. 1, adhesively secured to a reflecting backing 10, 11, the spheres are partly embedded in an adhesive 13 which contains a reflecting pigment, and make contact on their rear surfaces with a transparent layer 12 which spaces them from the backing, so that rays c approximately normal to the surface pass through the spheres to the rejecting backing, whilst rays b at an acute angle are reflected from that zone of the interior of the spheres which contacts the pigmented adhesive. The reflecting backing and the pigmented adhesive may be differently coloured, so that the colour of a road or advertising sign illuminated at night by car headlamps changes from that of the backing to that of the adhesive layer as the car approaches the sign and the angle of incidence of the rays becomes more acute. The transparent spacing layer 12 may be overlaid with another transparent layer 18, Fig. 2, in which the spheres are partly embedded to ensure a good optical communication with the backing. The backing may be aluminium foil, or waterproofed paper 10 or a non- fibrous film, e.g., of polyvinyl butyral coated with a varnish 11 containing aluminium flakes or white or coloured pigment. The varnish may be a solution of polyvinyl butyral resin. The transparent spacing layer 12, Fig. 1, may be a solution in an aromatic hydrocarbon solvent of a drying-oil modified alkyd resin which is cured before the spheres are applied. The thin transparent coat 18, Fig. 2, may be a solution of a urea-formaldehyde resin, a glycerol phthalate resin, and a plasticizer such as castor oil or ricinoleic acid. The reflective binder comprises the composition used for the transparent spacing layer with added pigment such as titanium dioxide. The transparent spheres are applied while the transparent coat. 18 and reflective binder are soft, the surplus spheres are removed to leave a single layer, the sheet is nipped between rollers to force the spheres into the surface of the transparent spacing layer, and the sheet is cured by heating at 185‹F. for 24 hours. Specification 586,595 is referred to.

Title: Improvements in or relating to advertising devices
IPC: G09F11/12
Filed: 1927-07-14
Abstract: 280,855. Lau, D. H. Nov. 22, 1926, [Convention date]. Sheets, travelling.-In an advertising device the advertisements are mounted on rods 23 which are assembled in magazines 15 and are withdrawn therefrom by an endless chain 5 furnished with hooks 24 the magazines being provided with fixed and movable teeth for displacing the rods 23 remaining in a magazine each time a rod is withdrawn. A motor 3, Fig. 1, drives a wheel 41, on the spindle of which is mounted a wheel 4 for driving the endless chain 5 and a wheel 6 for driving an endless chain 7. The chain 7 drives wheels 8, 9, and through them upper and lower wheels 13, 11 for operating a movable rack-plate 16. This plate is carried by a horizontal bar having a depending portion 42, Fig. 2, in contact with an eccentric 18 mounted on the same shaft as the wheel 13 and a wheel 44. This latter wheel is provided with a finger 19 which actuates a lever 20 pivoted to a fixed plate 14 perforated at 22 to enable a pin 21 on the movable plate 16 to engage a slot in the end of the lever 20. Rotation of the wheel 13 causes the eccentric 18 to raise the plate 16 to engage the rods 23 after which the finger 19 strikes a lever 20 to move the plate 16 laterally a distance of one tooth; subsequent movement of the eccentric lowers the plate 16 and deposits the rods 23 in the magazine 15. An upper and lower magazine are provided on each side of the case 1, the upper magazines having one tooth less than the lower; similar driving mechanism is provided at each side of the case. Referring to the operation of the mechanism on one side only, as the hook 24 passes round with the endless chain 5 it removes a rod 23 from the lower magazine and deposits it onto a support 25 after passing over a wheel 26; the. advertisement may then be viewed through a window 2. A wheel 28 is provided with a. depending pivoted bar 29 and hook 30 which latter, in a revolution, of the wheel 28, removes the rod 23 from the support 25 and deposits it onto an extended tooth 31 on the magazine 15. The hook 24 is then carried round to the other side of the magazine where it strikes a projection 35 of a pivoted lever which ejects a, rod 23 from the magazine 15 onto the hook 24. The rod 23 is then carried down and deposited on the end tooth of the lower magazine 15. The dimensions of the wheels actuating the endless chain 5 and of the wheels actuating the mechanism of the magazines are such that a complete revolution of the chain 5 and the hook 24 which it carries, corresponds to a. complete movement of the mechanism of the magazines. The apparatus may be illuminated and may display fabrics, lace, etc. and flexible articles in general.
