Patent GB-1302476-A (GB)
IPC: B63B43/00
Filed: 1971-04-19
Abstract: 1302476 Tankers N G R POLVIANDER 19 April 1971 [16 April 1970] 27296/71 Headings B7A and B7S A tanker has an intermediate bottom 4 in at least one of the compartments formed by longitudinal and transverse bulkheads 9, 6 and well below the water line 5 so that external water pressure is greater than internal oil pressure in the lower tanks 2 and oil leakage is prevented in the event of tanks 2 being holed. Lower tanks 2 are equipped with emptying and filling pipe 16, extending to the tank bottom, and a pipe 16 extending just below bottom 4 for emptying in the event of holing. Pipe 15 is for exhaust gas. Bottom 4 may be installed in a completed conventional tanker by cutting a thin rectangular panel from the tanker's side below the water line and sliding the prefabricated bottom into the hull on guiding angle girders located on transverse bulkheads 6.

Title: Improvements in and relating to the transmission of ultrasonic vibrations
Inventor: BRADFIELD GEOFFREY
IPC: G01N29/265
Filed: 1951-11-21
Abstract: 766,984. Ultrasonic inspection devices. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 20, 1953 [Nov. 21, 1951], No. 27326/51. Class 118 (2). [Also in Group XXXIX] The coupling (see Group XXXIX) connecting an ultrasonic transducer, e.g. piezo-electric, to a solid body, enables the angle at which vibrations are received from or sent into the body to be varied without movement of the member engaging the solid body. The transducer is mounted on a pad 14 on the cylindrical surface of a wedge 13 slidable on a bolster 12 contacting the solid body 11. The bolster 12 is clamped in position by a bracket 38 bearing on studs 21 in the bolster. Plates 29 secured to the bolster 12 carry spring-loaded rollers 36 running on flanges on the .wedge 13 and a manuallyrotatable pinion 32 which engages a rack 33 on the wedge 13 to slide the wedge 13 over the bolster 12. The pad 14 which is spring-urged against the wedge 13 is secured with play to arms 26 on a pivot 17 on members 18 fixed to the wedge 13. Links 19 pivoted on the studs 21 have slots to receive the ends of the pivot 17 and pins 25 threaded into the pad 14. In order to compensate for changing distance between the transducer and the body 11 when the position of the wedge is adjusted, it is arranged that movement of the pin 25 in the slot in the arm 19 controls an electronic delay device governing the start of the time base sweep of a cathode-ray tube indicator. In a modification a second wedge similar but at right angles to the first is adjustably mounted on the pad 14 and a second pad carrying the transducer co-operates with the second wedge. The second wedge projects through slots in the arms 26 and links 19 and its movement is controlled in a similar manner to that of the first wedge, but the links are pivoted to the pad 14 instead of the bolster 12. It is stated that information derived from a scanning movement of the transducer may be displayed in a similar manner to that employed for radar. Further, that scanning by orthogonal or spiral movements can be used and the results presented on a cathode-ray tube in amplitude or intensity modulated form. Also that since films of oil are necessary between the sliding parts, intermittent scanning movements with application of pressure to the sliding parts when stationary is desirable, bursts of high pressure oil being fed through ducts in the parts to free the sliding surfaces when about to be moved. Specifications 766,982 and 766,983, [Group XXXIX], are referred to.

Title: Knife sharpener mechanisms
IPC: B24B21/00
Filed: 1972-06-12
Abstract: 1379107 Sharpening machine cutters in situ EASTMAN MACHINE CO 12 June 1972 [15 July 1971] 27337/72 Heading B3D  A knife sharpener mechanism for a cutting machine having an elongate knife 15, comprises a grinder carriage 19 movable longitudinally of the knife, an abrasive belt or band 40 on the carriage, means for moving the bandtransversely relative to the cutting edge of the knife to sharpen the knife, a shoe 47 on the carriage biased by means 58 towards the knife to cause the band to engage the knife, and detent means 67 for restraining the shoe against movement towards the knife as the carriage is moved longtudinally relative to the knife while permitting the shoe to move away from the knife when the pressure between the shoe and knife exceeds the pressure biasing the shoe towards the knife. The cutting machine is for cutting cloth and consists of a standard 13 which extends upwardly from a base 12 and supports a frame 14 housing a motor for reciprocating the knife 15 in a vertical guide 16. A presser foot 17 is mounted at the lower end of a vertically adjustable bar 18. The carriage 19 is carried by a shaft 20 which has left and right hand threads whereby the carriage can be raised and lowered. The carriage has a block 25 which is formed with a pair of legs 23, 24 and rotatably supports a pair of pulleys 28, 29 driven in opposite directions by shafts 26, 27 from the motor. A first abrasive band 30 encircles pulley 28 and a spring- loaded pulley 31 on leg 24, and a second abrasive band 40 encircles pulley 29 and a spring-loaded pulley 41 on leg 23. The bands are urged against the knife edge by hardened inserts 55, 64 on blocks 53, 61 at the ends of shoes 46, 47 urged about pivots 49, 57 by springs 50, 58. Band 40 is disposed below band 30 and in order that band 30 may engage the lower end of the knife 15, band 40 is held against pivoting under the end of the knife by the detent means which consists of a finger 65 extending upwardly from shoe 47 and formed with an edge 77, and a series of serrations 76 which are engaged by the edge and formed on a plate 75 carried by an arm 66 urged by a spring 71 about a pivot 67 on the carriage 19. During sharpening, as the carriage is lowered, the reaction caused by the bands engaging the knife and the reduction in the support of the carriage causes the carriage to move laterally and the shoe 47 is permitted to yield by the edge 77 of the finger sliding over the serrations which only permit the edge to move in one direction. When the carriage is raised to its upper position, a cam 89, 92 on the frame 14 engages surfaces 90, 91 on the shoes 46, 47, which are thus disengaged from the knife, and a surface 93 on the plate 75 of arm 66 to disengage the detent means. Upon downward movement of the carriage, the cam first disengages the surfaces 90, 91 on the shoes so that they are positioned by engagement with the knife and then disengages the surface 93 so that the detent means is engaged.

Abstract: 905,245. Knot-tying devices. ZELLWEGER Ltd. Aug. 8, 1960 [Nov. 30, 1959], No. 27425/60. Class 112. The stripper which removes the completed knot from the beak of a knot-tying device is resiliently connected with its driving member. The stripper comprises two levers 6, 7 pivoted about a common pivot 8. A spring 9 pulls the levers together until a flank 7a on the lever 7 abuts the lug 6b on the lever. When the thumb lever 1 is depressed the beak 4 is rotated by the engagement of a fork 2 with a spiral 3. Shortly before the end of the movement of lever 1 the fork 2 abuts a cam face 6a to move the stripper head 10 towards the beak, the head being held down by engagement with the threads tensioned between the thread gripper 11 and the beak 4 until the latter has completed its movement and is in the correct position for the stripper to strip the knot.

Abstract: 304,170. Jordan, F. Oct. 15, 1927. Hollow-ware. - Aluminium-plated sheet-iron parts are welded together autogenously without additional welding material by heating them by the electric resistance process with the aid of pressure electrodes so a;s to convert the aluminium into oxide, which melts together with the iron to complete the weld. In welding a cover to a receptacle the flanges of the body d and cover f are welded at s, the flange d<1> is then bent over the cover flange and the three layers then bent over against the outside of the body so as to obscure the aluminium oxide in the outer sides of the seam. In a further form the cover has a projecting rim which, after welding, is bent over the end of the body and the three layers then bent as shown in Fig. 8 to obscure the oxide.
