Abstract: 899,392. Poultry houses. BRADSHAW, R. A. April 11, 1961 [Dec. 29, 1960], No. 44536/60. Class 5(2). Apparatus for housing livestock particularly poultry comprises a house 21 supported on a frame 13 mounted on flanged wheels 15 which run on circular tracks 10, 11. A food hopper 29 is arranged on the wall of the house above a platform 25 carried by a pivoted lever 26 which depresses under the weight of a bird alighting on the platform. The movement of the lever acts on a pawl 31 engaging a ratchet wheel 33 attached to a spool 34 carrying a wire or cord 35 which is led through the wall of the house, round a pulley 36 and anchored to a stake 38. Each time the platform is depressed the pawl 31 advances the ratchet wheel one tooth causing the spool 34 to rotate slightly and the cord or wire to be wound in on the spool so that the frame is moved round the track. The house 21 occupies half the length of the frame and is moved along the frame after a revolution has been completed.

Abstract: 1,201,472. Purification of organic acids. TENNECO CHEMICALS Inc. 3 Oct., 1967 [5 Oct., 1966], No. 44950/67. Heading C2C. A sublimable aromatic monocarboxylic acid having on its aromatic nucleus one or more substituents additional to the carboxyl group is purified by heating it with a gas which is inert to the acid, e.g. air, nitrogen or carbon dioxide, and is heated to a temperature sufficient to effect sublimation, the heating of the acid being effected in the presence of at least 0À5% by weight based on the acid of a finely-divided solid activated adsorbent, and cooling the resulting sublimate gas stream in a separate zone to obtain the purified acid. Suitable adsorbents include, for example, acid-activated clays such as fuller's earth, kieselguhr, flondin and montmorillonite, and activated silica gel, alumina and carbon. Suitable acids for purification by the process are, for example, salicylic acid, p-hydroxybenzoic acid, 2,3,4-trihydroxybenzoic acid, 5 - hydroxy - 1 - naphthoic acid, o-, m- and p-chlorobenzoic acids, o-bromobenzoic acid, m- and p-iodobenzoic acid, 2,4- and 3,4-dibromobenzoic acids, 2,4-, 2,6-, 3,4- and 3,5-dichlorobenzoic acids, 2,3,5- and 3,4,5 - trichlorobenzoic acids, m - aminobenzoic acid, p-nitrobenzoic acid and m- and p-benzylbenzoic acids. The impure salicylic acid used as starting material may be obtained by the treatment of an alkali metal phenate with carbon dioxide.

Abstract: 1,057,366. Cassettes; magnetic recording &c. apparatus. R. G. H. WILLIAMS. Nov. 27, 1963 [Nov. 30, 1962], No. 45364/62. Heading G5R. A cassette for magnetic tape or the like comprises two hubs or spools arranged coaxially one above the other within a housing, and guiding means for guiding the tape to and from the spools and to and from an operative run, the operative run being at right-angles to the axis of the spools in a plane parallel to the axis and at a level between the levels of the spools. The cassette shown in Figs. 1 and 2 comprises hubs 5 and 6 loosely mounted in cups 9 formed in a central plate 1 to which transparent covers 3 and 4 are secured. The tape 7 passes from hub 5 via guide posts 11 and 13 to an operative run 24 and then via guide posts 14 and 16 to the hub 6. Guide posts 11 and 13 are joined together by an arm 19 and are shaped to allow the tape to slide over them readily from the higher level of hub 5 to the intermediate level of the run 24. The minimum angle of contact around post 11 should be 60 degrees and the angle of contact around post 13 should be at least 80 degrees. The tape is twisted in passing between the posts and the angle of twist should be less than 45 degrees and preferably about 28 degrees. The hubs 5 and 6 are braked by serrated brake blocks 20 engaging the serrated inner surface of a flange 21 formed upon each hub, the blocks 20 being joined to a common operating arm 22. The cassette is provided with locating apertures 33 for locating it on a tape deck, and with reentrant portions 18 to allow a capstan and transducing heads to contact the operative run 26 of the tape. Recording apparatus.-Fig. 6 shows a tape deck for use with the cassette. Locating posts 32 pass through the locating apertures in the cassette and one of them operates arm 22 to release the brakes. A main motor 34 drives a capstan 38 via pulleys 35 and 36 and flywheel 27, and also drives a re-wind pulley 37 adapted to engage the lower of the two hubs in the cassette via a clutch. A take-up motor 42 is coupled by pulleys 44 and 45 to a further pulley (not shown) secured to a shaft 47 which passes through the central apertures of the hubs of the cassette and has a spring-loaded arm 48 adapted to engage a radial groove in the upper hub. Pads 51-53 are provided respectively for take-up back tension on the re-wind pulley, re-wind back tension on the takeup pulley, and braking for the take-up and rewind pulleys. Locating posts 32 may be used to detect the presence of a portion of metal tape and thereby initiate a further function such as braking or reversal of the tape drive. Each post may comprise two conductive portions separated by an insulator, and the metal tape can be arranged either to cause connection between the two conductive portions or between the two posts.

Relates to a scribing device of the kind in which a writing instrument is carried in an aperture 12 in a member 11, and is directed over the surface to be written upon by a tracer pin 22 movable in character grooves in a template and by a tail pin (18, Fig. 6) movable in a groove parallel with the line of lettering. The writing instrument is retained in the aperture 12 by a pair of clamping levers (28, Figs. 8, 9) of angle section arranged with their webs in abutting relation and received in a groove (27) on the side of the device. The outwardly directed flanges 29 of the levers lie against the outside of the device, and a spring (32) supplies the biasing force. A lever (35, Figs. 6 and 9) pivotally mounted intermediate its ends on the tail bar 14 of the device, has a foot or leg (36) which can be projected through the body of the device to lift the writing instrument away from the surface to be marked. The angular position of the arm carrying the tracer pin 22 can be adjusted in relation to the body-plate 10 of the device to vary the inclination of letters drawn. A threaded spacer screw 51 is provided to obtain the desired spacing of the point of the writing instrument, and is particularly necessary when the writing instrument is a pen.

Further keys 13a, 14a, 16 control vector length (one or two units), vector blanking, and broken-line display respectively, and a key 15a enables transfer of control between the graphics keyboard and an alphanumeric keyboard 11a. This latter has, in addition to alphanumeric character keys, positioning keys (tabulating keys vt, ht, carriage return cr and home h) which are used for positioning alpha display and the start of line drawing. Alphanumeric characters are traced by selective unblanking of appropriate ones of a set of strokes. Data words are held in a circulating refresh store and pass via gates controlled by a bi-stable holding a mode control bit to a vector decoder or alpha decoder for subsequent generation of the necessary ramp voltages for addition to positioning voltages from A/D converters. Recognition of a mode change signal switches the mode control bit. The necessary logic circuits are described with the aid of schematic diagrams.

Abstract: 1,000,939. Decimal adders. CONTRAVES A.G. Nov, 21, 1963 [May 7, 1963], No. 45948/63. Drawings to Specification. Heading G4A. A parallel adder uses a decimal code with weights 4221, the addition of two coded decimal digits (and carry from lower order) being effected by an arrangement of binary full adders giving a provisional result which is either correct, or in error by a value two which can be corrected by changing the next-to-lowest bit only. The error occurs if there is a carry out of this order, or out of the decimal stage (regarding this carry as equal to ten, for transmission to the next decimal order) but not both. The code, and logical equations and their realization for deriving the corrected term, are described and illustrated schematically. Since the sum, while being correct insofar as the weighted sum of its bits is correct, may not correspond to a decimal digit in the original code, the invention is stated as being particularly applicable to obtaining analogue signals from the digital output.
