Filed: 1956-09-27
Abstract: 799,288. Fishing tackle. MEULNART, A., and M. E. P. P. S. MANUFACTURE D'- ENGINE DE PRECISION POUR PECHES SPORTIVES. Sept. 27, 1956 [Aug. 21, 1956], No. 29598/56. Class 48. A fishing tackle comprises a telescopic rod 1 upon which is mounted a reel 3 adapted to be folded against the rod (as shown) so that the handle 5 abuts the rod and is thereby prevented from rotating in a line unwinding direction and an opening 11 in the handle adapted to be engaged by the hook 12 so that the tensioned line 9 mounted on the rod keeps the telescopic parts thereof in closed position and also holds the handle against the rod, the hook being protected by the flyer 6, the rod and the handle. The reel is pivoted on a pin 4 on an arm 2 adapted to attach the reel to the rod. After engaging the hook in the opening 11 the line is tensioned by turning the spool 8 by hand whilst preventing the flyer 6 from rotating.

Title: Method for the Automatic Stabilization of the Tension of Metal being Rolled in a Continuous Rolling Mill
Inventor: GETMANETS VENIAMIN VASILIEVICH
IPC: B21B37/50
Filed: 1967-06-28
Abstract: 1,171,504. Rolling. INSTITUT CHERNOI METALLURGII. 28 June, 1967, No. 29746/67. Heading B3M. [Also in Division G3] The tension in a rolled product is automatically kept constant between adjacent stands of a rolling mill by controlling the drive of one stand in response to the difference between the measured tension of the product and a reference tension, the vertical slack of the product between the stands giving a measure of the tension. The vibration frequency of the product may additionally be used to indicate the tension. A slack position detector 1 is initially connected by a switch 3 through a follow-up and memory unit 4, and when a slack value corresponding to a desired tension is obtained, an operator switches the detector through a comparator 5, the unit 4 then retaining the slack value as a reference. Any subsequent difference between a measured slackness and the reference is used to control the drive of one stand of the mill in a sense to decrease the difference. The detector 1 can also carry information relating to the vibration frequency of the product in a vertical plane and this information can be used in a similar manner to first obtain a reference value and then, after switching, to control the speed of a mill stand.

Title: Improvements in hose pipes
IPC: B29C63/00

Abstract: 836,879. Flexible hose pipes. HANSSENS, G. J. J. July 2, 1956 [Oct. 21, 1955], No. 30197/55. Class 99(2). In a method of making a hose pipe capable of being rolled flat, a fabric tube 11 is coated internally with a suspension dispersion, or solution of a thermoplastic polyvinyl compound and a tube 10 of thermoplastic polyvinyl compound is inserted therein, the tubes being heated by external heating means to unite the tubes through the medium of the coating compound, and, during the heating, being rotated around the common longitudinal axis thereof. There may be an outer tube 12 of a thermoplastic compound, and the fabric tube may be of glass fibres, wholly or mainly of rayon fibres and may contain up to 50% of other artificial fibres such as nylon or perlon, or the tube may be wholly or mainly of fibres of a polyester such as " Terylene" (Registered Trade Mark) or mainly of a polyamide such as nylon. Impregnation of the fabric tube may be effected by filling the tube with an emulsion of polyvinyl chloride and passing the tube between a pair of squeeze rollers to force the emulsion into the interstices of the fabric. As shown, the assembled hose is threaded into a braided support tube 14, of wire or textile threads, one end of which is clamped to a rotatable tube 24 driven by a motor 25, the other end of the tube being attached by a clamping device 26 to a cable 28 tensioned by a weight 36. The free end of the hose is sealed by a plug 50 and compressed air is admitted through a conduit 31 to the hose. An infra-red oven 34 traverses the rotating hose for which forked supports 40 are provided, these supports being spring-urged to an upright position and deflected downwardly by the oven as the latter passes along the hose. After bonding of the layers of the hose, the tube 14 is removed. To permit the escape of air present between the tubes of the hose the outer tube is perforated by passing the tube between a pair of rollers having radial pins ; the fabric tube 11 may be dried before or after the impregnation thereof. To reduce deterioration of the fibres of the fabric tube, an opacifier such as aluminium powder or a pigment such as titanium oxide, or a mixture thereof, is added to the impregnating material ; alternatively, or in addition, an opacifier is incorporated in the cover tube 12. In modifications, the fabric tube and lining are bonded together without the use of the tube 12 which is applied subsequently either as a liquid coating or by wrapping sheet material around the fabric tube and securing the sheet by adhesive, or by the use of heat and pressure, and the heating of the hose is effected by a heated pressure fluid, or the layers of the hose are bonded together by external pressure by supporting the hose on an internal mandrel and contracting a braided outer tube on to the hose. To protect the end of the fabric tube, the end edges of the hose are covered with an extra layer of thermoplastic material, or the ends of the hose are turned back and covered with such a layer. Specification 836,878 is referred to.

A magnetic head for simultaneous recording and reproducing has a core with a portion common to two separate flux paths each of which has a high reluctance gap, recording and reproducing coils wound on separate portions, each of the portions being associated with one path only, and means for eliminating any net flux linking the coils. In the first embodiment, Fig. 1, the core comprises a U-shaped part 10 carrying a coil 22 and an E-shaped part 14 carrying a coil 24 on the middle limb. The two parts 10, 14 are joined by an intermediate portion 16 to form signal gaps 18, 20 associated respectively with the signal coils 22, 24. The arrangement is in effect a magnetic bridge circuit, Fig. 2 (not shown), which may be roughly balanced by notching the core as indicated at 31, and finally balanced by an adjustable shunt in the form of a screw 26. The arrangement of the coils at right angles to each other reduces the effect of external fields. In an alternative embodiment, Fig. 3, the core has three substantially parallel branch portions, the central branch being divided. Shorting coils 56, 58 associated with coils 50, 52, respectively, are provided which each link one particular portion each of the divided branch portions. Thus two flux paths are provided which do not link either of the shorting coils, but do link the signal coils 50, 52 and there is thus no interaction between changes of flux in the two flux paths. Fig. 4 shows a combination of the arrangements of Figs. 1 and 3.
