Title: Hosepipe-making machine
IPC: B29C53/60
Filed: 1963-02-14
Abstract: 963,054. Hose pipe-making machines. AIR REDUCTION CO. Inc. Feb. 14, 1963 [Feb. 15, 1962], No. 6084/63. Heading F2P. A mandrel 1 extending coaxially from a drive shaft 2 is surrounded at the end thereof adjacent the shaft by a fixed helical guide 4, the inner surface of which is contiguous to but clears the mandrel to form a helical guide face 6 at the axial outer end of the guide, and there are means for directing a first hose element 7, tangentially on to the mandrel and contiguous to the helical face whereby the latter forces the element to progress axially on the mandrel as the mandrel rotates, and means for applying a second hose element 9 over the element 7. As shown, the mandrel which is supported by a driven shaft 2 is provided with longitudinallyextending serrations 3, and the member 7 is guided on to the mandrel by a guide helix 4 the pitch of the face 6 of which determines the pitch of the helical wrapping. The tensioned tape 9 is fed towards the mandrel by a guide 10 and adhesive may be applied to the tape. A pressure roller 11 places the core member 7 under slight tension to cause the convolutions thereof to grip the mandrel and the coiled member is forced axially of the mandrel by the face 6 of the member 4. In a modification, rollers 15, Fig. 4, are arranged in three sets on shafts 16 to define a helical path, and the core member 13 is circular in cross-section.

Filed: 1950-03-10
Abstract: 826,417. Electric measuring systems. SPERRY GYROSCOPE CO. Ltd. March 9, 1951 [March 10, 1950], No. 6094/50. Drawings to Specification. Class 40 (1). In an aircraft navigation computing device a spherical polar co-ordinate system is used and acceleration is measured by three mutually perpendicular accelerometers, of the differential capacitor type, described in Specifications 804,849 and 826,418, [Group XX], and then doubly integrated. The accelerometers are gyroscopically stabilized in the vertical, East- West and North-South directions respectively and the action of each is modified by electromagnetic biasing coils, to allow for both flight curvature due to passage over the earth's surface, and to the speed of rotation of earth. The output of each accelerometer is first supplied to a phase-sensitive rectifier and then integrated by a high-gain D.C. amplifier, having negative feedback, as described in Specification 666,882, and the three amplifier outputs are supplied to a single computer which derives the craft spherical co-ordinates and displays them on separate indicators. The computer also derives the accelerometer modifying signals by means of sine and cosine potentiometers the tappings of which are moved by the shafts operating the indicators. Specifications 641,778, 718,171, [both in Group XXXV], and 735,856, [Group XXXVI], also are referred to.

Abstract: 699,701. Disc brakes. DUNLOP RUBBER CO., Ltd. Feb. 13, 1952 [March 14, 1951], No. 6204/51. Class 103(i).  A disc brake, more particularly for heavy commercial vehicles and track-laying vehicles such as tanks, comprises a plurality of axially spaced discs 1 and 2, rotatable by movement of the vehicle, which are connected together at a periphery, each disc being straddled by non- totatable housing parts 11 and 13 having associated fluid pressure operating mechanisms for urging friction pads into engagement with the discs. As shown in Fig. 2, the housing part 11 straddling the disc 2 carries hydraulically-operated plungers 18 which press pads 19 into engagement on each side of the disc. Similar hydraulic actuator means is carried by the housing part 13 straddling the disc 1. As seen from Fig. 1, there may be four adjacent hydraulic actuator cylinders carried by the housing parts each of which extends over only part of the circumference of the disc. A handoperated spring-urged tooth member 24, Fig. 3, may be used to engage teeth 23 on the periphery of disc 1 to act as a parking brake. The Provisional Specification describes the use of wear-indicator rods secured to a plunger and extending through the cylinder housing.

Abstract: 1384273 Sewing UNION SPECIAL MASCHINENFABRIK GmbH 11 Feb 1972 [16 Feb 1971] 6398/72 Heading DIG Reinforcing the ends of a seam by backtacking is carried out automatically, at the start of the seam by stitching forward and then bank the same number of stitches before commencing the seam proper, and at the end of the seam by stitching backwards and then forward again for a set number of stitches after a photo cell detects the trailing edge of the material. Depressing the left-hand end of the treadle 9 starts the motor 6 and energises a relay 15 which starts a counter 21. The counter, after a predetermined number of stitches, energises a magnet 11 to reverse the feed for the same number of stitches before de-energising the magnet again. Towards the end of the seam the right hand end of the treadle is depressed to switch the motor to a predetermined speed and prepare a second counter 18. When the photo cell 24 detects the trailing edge of the material the feed is reversed and the counter counts a predetermined number of stitches before returning the feed to the forward direction. In modifications RC timing circuits could replace the counters, or pneumatic switches could replace electric switches.

Title: Primary aryl monoamines containing a thiosulphuric acid group and process for their manufacture
IPC: C07K1/00
Filed: 1960-02-25
Abstract: Primary aryl monoamines containing a thiosulphuric acid group, which is linked to the nucleus, either directly or through a bridge member, in a position other than ortho to the amino group, are prepared by reducing the salts of the corresponding nitro-compounds in the presence of metallic iron and ferrous ions in a substantially neutral aqueous medium. The products in which the aryl nucleus is of the benzene, naphthalene, diphenyl or diphenyl ether series and is not further substituted, or is substituted by halogen atoms or alkyl or alkoxy groups, and in which the thiosulphuric acid radical is linked to the nucleus either directly or by a group -CH2-, -SO2-NH-CH2-CH2, -SO2-N(CH3)-CH2-CH2- or -CO-NH-CH2-CH2-, and claimed as new compounds. The preferred source of ferrous ions is ferrous sulphate, and when a sodium salt of a nitroaryl thiosulphuric acid is reduced the presence of ammonium chloride or a magnesium salt may be advantageous. Examples are given of the manufacture of 3-aminophenyl thiosulphuric acid, 3-amino-4, 6-dichlorobenzyl thiosulphuric acid, 3-amino benzenesulphonylmethyl - b  - aminoethyl thiosulphuric acid, and 3-aminobenzyl thiosulphuric acid.

[Class 64 (i)] [Also in Group XXIX] A gas-heated apparatus 4 provided with a damper 6 in the flue 5 has a safety device to ensure that the gas cannot come on until the flue is fully opened. This device controls the automatic safety cut-off valve 3 in the main gas pipe 1 which comprises a valve member 19, Fig. 2, normally held open by the outlet gas pressure acting on a diaphragm 23 in a chamber 15 through a passage 21 with a restriction 14 so that the valve closes on failure of pressure. The valve must be re-opened by manual operation of a push-button valve 22, Fig. 3, to allow pressure from the inlet to act through passages 13 and 26 on to the diaphragm. A pipe 10 is taken from the diaphragm chamber to a valve cock which is actuated by the spindle of the damper 6 to vent this chamber to atmosphere through passages 17, 16 when the flue damper 6 is closed so that the valve 19 cannot open under these conditions. When the damper 6 is fully opened, by a lever 8 acting through a link 7, the vent 17, 16 is closed so that pressure is allowed to build up underneath diaphragm 23 and open the valve 19. A pressure regulator and a bimetallic safety-device may be combined with the cut-off valve 3.
