Title: Self-straining bolts
IPC: F16B31/04
Filed: 1972-03-08
Abstract: 1382192 Pistons P & O RESEARCH & DEVELOPMENT CO Ltd 5 March 1973 [8 March 1972] 10599/73 Headings F2H and F2T  In a self-straining bolt comprising a shank 11, a rod 23 fitting with clearance in an axial bore 16 in the shank, a cylindrical pressure chamber 18 secured to the end of the shank remote from the closed end of the bore, a piston 24 which is slidable in the chamber 18, engages or is integral with the end of the rod 23 adjacent the chamber and is pressurized by fluid under pressure supplied through a conduit 30 in the chamber wall in order to strain the shank of the bolt; the piston is sealed by a disc 29 abutting the working face of the piston which disc is of resilient material having a hardness within the range 10 to 100 Shore hardness and a thickness of at least # inch. The disc may be of nitrile rubber and preferably has a Shore hardness between 40 to 70 and a thickness of at least ¢-inch. The piston may have a radius 27 adjacent its working face and its wall may be tapered away from the working face. The chamber 18 is formed by a cup-shaped body 19 threaded at 21, 22 to the bolt shank 11 and the piston is secured to the rod 23 by a threaded rod 25. The conduit 30 is connectible by a pipe 34 to a source of pressure fluid via a valve 32. In operation, normally before the bolt is inserted in the workpiece such as plates 40, 41, the bolt is pretensioned by connecting the pipe 34 to a pressure source and opening the valve 32 to thereby pressurize the piston and force the rod 23 against the closedend 17 of the bore 16 to strain the shank until the piston abuts the end face 42 of the bolt head 14. The valve 32 is then closed and the pipe 34 disconnected. When required, the bolt is inserted in the apertures in the plates 40, 41 and the nut 13 screwed on the bolt to engage the plate 41, the valve 32 is then opened to relieve the hydraulic pressure and the body 19 is removed from the bolt. A cover 44 and 0-ring 45 are fitted as shown in Fig. 2 to protect the threads 22 on the bolt head. To remove the bolt the process is reversed.

Title: Improvements in thermostatic controllers for water heaters
IPC: G05D23/00
Filed: 1921-04-12
Abstract: 182,916. Ryan, B. April 12, 1921. Thermostats.-Relates to heating-apparatus in which a supply of hot water in a storage tank is constantly maintained at a predetermined temperature by a thermostatic device comprising a fixed magnet and a movable armature which operates to shut off completely the gas supply to the heater having only a pilot light when the temperature of the water exceeds the predetermined limit. In order to secure, inter alia, a quick snap closing of the valve 27 controlling the gas outlet 8 which is arranged between the actual thermostat 7 and the gas inlet 11, the leverage between the thermostat and the valve comprises a member 15 pivoted at 14 and directly controlled by the thermostat, a second lever 19 carrying the valve 27 and also i.he armature 23 arranged over the horseshoe magnet 12, whilst a third member 32 pivoted to the casing at 33 engages at one end the bridge-piece 16 carried by the lever 15 and the other end is connected to the lever 19 by a spring 22. With this construction, when the contraction of the thermostat tube 6 moves the rod 7 to press upwardly a screw 36 in the lever 15, the consequent upward movement of the lever 19 does not operate the valve but causes the lever 19 to swing on its pivot 18, thus putting the spring 22 into tension. This tension is accentuated by the lever 32, which is swung so that its outer end moves away from the lever 19. The tension on the spring eventually overcomes the magnetic pull upon the armature and finally the valve 27 is moved from its seat with a snap. The valve spindle 28 passes through a slot in a removable .bridge piece 25 which permits access to the valve and valve seat without disturbing the adjustment of the valve a removable plug 47 being arranged above the valve. Compression springs are employed to hold temporarily the valve on its seat during transit and the casing may be made of an aluminium alloy. A device is provided for adjusting the temperature at which the thermostat operates.

Title: Process for the production of coated articles
Inventor: CRAMM RUSSELL HENRY
IPC: C08J7/052
Filed: 1960-03-25
Abstract: Coated articles are made by applying a thin adhesion-promoting layer of a polyalkylene imine to the activated surface or surfaces of olefin polymer substrates and then applying polyvinylidene chloride to the thus modified surfaces.  Polyethylene imine and polyethylene are the preferred materials.  The surfaces may be activated by treatment in a burning flame or by electrical discharge (electron bombardment). The polyalkylene imine may be deposited from solution in acetone, methyl ethyl ketone, or methanol and other alcohols, particularly those having less than 4 carbon atoms in the molecule. The vinylidene chloride may be applied as a polymer or copolymer with compounds such as vinyl chloride, acrylonitrile, acrylic acid or an acrylic ester; in such copolymers the vinylidene chloride should be present in amount at least 25% by weight of the polymer.  Articles such as containers may be coated on both inner and outer surfaces as desired.

Abstract: 1386349 Endless conveyers MARSHALL HANDLING EQUIPMENT Ltd 26 Feb 1973 [8 March 1972] 10676/72 Heading B8A A carrier 4 suspended from an overhead endless conveyer chain 8 is arranged to receive loadcarrying trays 5 from a series of feed conveyers 24, 16, 17, and to discharge trays 5 to a series of take-away conveyers 13, 14. These operations are initiated by the action of a code block 9 carried by each carrier 4 as the latter approaches the feed/discharge station. When the block 9 passes code readers 10, a signal is generated to cause the conveyer 17 to be lifted by a jack R to the position shown, from the position illustrated in Fig. 1 (not shown). A sidewall member 25 adjacent the conveyer 17 engages (when this conveyer is in its raised position) the tray 5 on the passing carrier 4 thus causing this tray to be deflected on to the take-away conveyer 13. A detector D4 starts the conveyer 13. Passage of the carrier 4 past a detector D5 causes a stop 23 to be lowered, and the re-starting of conveyer 16. A detector D2 returns the stop 23, and a detector D1 stops the conveyer 16.

Title: Improvements relating to rotary engines or motors
IPC: F02B53/00
Filed: 1931-04-14
Abstract: 367,234. Rotary engines. DEDIEU, J., His par Gastagnede, Haute Garonne, France. April 14, 1931, No. 11033. Convention date, April 14, 1930. [Class 110 (ii).] An intermittent-abutment type of internalcombustion engine comprises pistons B moving around an annular chamber A which is provided with inlet ports I and exhaust ports J. Connecting links C are pivoted to a rotor D by pins O and to the pistons B. Fixed cams F bear on pins attached to the connecting links and cause the appropriate pistons to accelerate towards the preceding pistons and compress the charge between them, by pivoting the connecting links C about the points O. A latch G, fixed to the stator, prevents backward movement of the second piston during the power stroke, while the first piston moves on, but due to the pivoting of the connecting link about the latch G, the piston reaction load impels the pin O forward and thus aids the rotor. The first piston is locked to the rotor, during the power stroke, by pins controlled by fixed cams. Annular segments of packing are carried around between each pair of pistons to seal the working space. The segments are supported by springs held by the connecting links. Cooling means comprises a water jacket M and fins N. Several engines may operate on one shaft, and superchargers may be fitted.

Patent GB-425074-A (GB)
Title: Electromagnetic brakes
IPC: F16D63/00
Filed: 1934-04-14
Abstract: 425,074. Electromagnetic brakes. FRASER, E. M., 26, St. Andrew's Place, Yonkers, New York, U.S.A. April 14, 1934, No. 11324. [Class 103 (i)] An electromagnetic brake comprises a magnet and a relatively rotatable armature without frictional contact, each having toothed poles, the number of teeth on the one member being a multiple of that on the other, and the poles on one or both members being preferably surrounded by copper in which currents are induced. In Figs. 1, 4, the electromagnet 1 secured to the stationary member 10 has toothed poles 2, 3 projecting through a copper grid 8 adjacent to teeth 13 on an armature 12 secured to the rotating member 11. The number of teeth 13 on the armature is half that on the magnet and each tooth 13 is at least equal to the pitch of the teeth 14, 15 of the magnet so that in all positions of the armature each of its teeth are offset with respect to an adjacent tooth of the magnet and the varying flux between the teeth induces currents in the grid around the teeth. The magnet may surround the armature or there may be inner and outer coaxial armatures and the magnet, provided with inner and outer poles, be disposed between them. One set of teeth may be inclined axially with respect to the other and the teeth may be divided to form a series of rows. Thus Fig. 14 shows magnet teeth 33 surrounded by copper 34 and armature teeth 36 that move from right to left and are arranged in transverse rows A, A<1>, B, B<1> and circumferential rows A, B, A<1>, B<1>, both sets of rows being inclined to the axis of rotation. The teeth 36 are shown as of triangular crosssection, but they may be of diamond shape so as to produce an equal action irrespective of the direction of rotation. Fig. 22 shows a toothed armature 95 projecting between the poles of a magnet 98, the pole pieces comprising a number of toothed rings 102 so arranged that the transverse rows of teeth are inclined to the axis of rotation. The armature may instead be of disc form as shown at 47, Fig. 16, with radial teeth 49 disposed between the toothed poles 40, 41 of the magnet. One set of teeth may be inclined to the radius or may be formed as a number of concentric rows with the teeth in staggered relationship.
