Title: Method of and arrangement for designing and copying garments
IPC: A41H3/00
Filed: 1930-08-08
Abstract: 366,906. Drafting garment patterns. BACHWITZ, A., 47, Lowengasse, Vienna. Aug. 8, 1930, No. 23812. Convention date, Feb. 20. Void [Published under Sect. 91 of the Acts]. [Class 141.] A method of drafting patterns involves the use of a reduced printed o utline for copying to the proper size and its' adaptation to certain measurements which have been taken. The reduced printed outline is produced by taking a full sized outline 1 cut out of black paper or the like, placing it on a sheet T containing a square mesh with certain additional indicating marks, and photographing the whole. Printed copies of the photographs may be in ladies' magazines and enable anyone to copy the outline to the required size by taking squared mesh corresponding to that originally photographed and making a copy of the required outline, slightly modified, if necessary, by the measurements taken on the human figure. The outline is then pressed through to a sheet of paper underneath, which is cut out to form the pattern. Various shapes and figures are used, as shown, to indicate position.

Title: Improvements in the preservation of latex
IPC: C08C1/06
Filed: 1955-08-18
Abstract: Latex or latex concentrate is preserved by adding thereto 0.001% by weight of an antibiotic or a mixture of antibiotics, of the kind which are products of the metabolism of microorganisms inhibitory to the growth of other micro-organisms.  The preservative may be sprayed on to the tapping panel or cut or added to the collecting cup, e.g. a mixture of streptomycin and penicillin, or of streptomycin and oxytetracycline, or of chlortetracycline, streptomycin, and chloramphenicol.  Ammoniated field latex of concentration 0.1 to 0.3% by weight of ammonia may be preserved during storage by adding thereto a mixture of streptomycin, aureomycin, and penicillin to provide concentrations in the latex above 0.005% by weight.  Latex concentrate containing ammonia may be preserved by adding thereto, to a concentration of over 0.001% by weight, a mixture selected from penicillin, streptomycin, oxytetracycline, aureomycin, and chloramphenicol.  When the antibiotic preservative is added to concentrated latex which does not contain ammonia, the mechanical stability of the latex may be improved by adding a wetting-agent or soap.  As a further example, Hevea latex or latex concentrate, the bacteria of which has been reduced or eliminated by ultrasonic vibration, ultraviolet irradiation, or subjection to high-frequency electric fields or a combination of these treatments may be protected against subsequent bacterial attack by the addition of the antibiotic preservative thereto.

Abstract: 990,482. Change-speed control. C. VAN DER LELY N.V. June 20, 1962 [July 18, 1961], No. 23841/62. Headings F2C and F2D. A tractor for drawing or pushing agricultural implements is so arranged that excessive draw-bar force causes an automatic adjustment of the transmission gear to reduce speed. The arrangement shown employs an hydrostatic transmission with swash - plate pump and motor units 12, 13, control being exercized on the pump swash - plate 19, but a mechanical transmission may be used. The pivot shaft 20 of plate 19 is connected to the output member 31 of an hydraulic servomotor unit 32, the input member 33 of which is operated by a manual control lever (not shown), carried by a shaft 10 and operating through a linkage 48, 45, 37. The upper end of member 37 is attached to a cross-arm 53, 54 whose ends are connected to spring- loaded longitudinal members 55, 56 which are attached to the power-lift linkage or other implement-sensing mechanism. Upon the draw-bar force exceeding a predetermined value one or other of the rods 55, 56 moves to displace cross-arm 53, 54 and member 37, thereby operating the servomotor input member 33 to tilt the pump swash-plate 19 to reduce pump output and thus the speed of the tractor.

Title: Improvements in or relating to acoustical recording machines
IPC: A47J39/00
Filed: 1930-08-13
Abstract: 357,724. Sound-recording machines. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Aug. 13, 1930, No. 24248. Convention date, Aug. 15, 1929. [Class 40 (ii).] Relates to gramophone-type apparatus for recording sounds, in which the smooth commencing grooves of the record are cut with a pitch and depth differing from that of the sound-record grooves. According to the invention, a recording cutter 10 is fed across the record by a feed screw 6 driven through free-running couplings 3, 4 from spindles 1, 2 which are driven at different speeds of rotation from motors 15, 11, respectively. The cutter 10 is mounted on a pivoted plate 7 which carries on its upper surface a contact 12 normally closed so that at the outset both driving spindles 1, 2 rotate and the turntable carrier 8 is driven by bevel-wheel gear 9 from the spindle 1. When the cutter 10 comes into contact with the record, the plate 7 assumes a horizontal position and the contact 12 is opened to de-energize a relay 17 whereby the more rapidly running motor 11 is disconnected from the supply mains 13. The motor 11 thus runs as a generator and the speed of the spindle 2 falls so that the cutter 10 inscribes an initial spiral with the pitch of the grooves decreasing from an initial maximum. At the same time a pressure magnet 14 is energized and, through a lever 19 integral with a plate 7 and connected to an armature 18, additional pressure is exerted on the cutter 10 so that the smooth commencing grooves are more deeply cut. When the speed of the spindle 2 falls to that of the spindle 1, the motor 15 takes up the feed of the cutter 10 at constant speed. In order that the speed of the motor 11 when switched over to generator working should not fall too rapidly, a flywheel 16 is coupled with its driving spindle 2.
