Title: Improvements relating to the manufacture of chains
Inventor: DUNN JOSEPH
IPC: B21L3/00
Filed: 1950-02-01
Abstract: 689,391. Making chains. DUNN, J., and ROBERTS, D. Jan. 22, 1951 [Feb. 1, 1950], No. 2581/50. Class 83 (iv). Welding by pressure.-In a method of making chains, each link is formed from an element which is bent into a loop with the ends forming a shouldered lap joint, the two overlapping portions forming a portion of greater thickness than that of the remainder of the element, and the joint is heated and forged by dies 17, 18 at opposite sides so as to weld the overlapping surfaces together. After the first forging the link is turned through 90 degrees and the dies reclosed on the work. A second pair of dies having smaller cavities may then effect two similar forging operations, without reheating. The links may be supported at their ends by supports 20, which may also constitute pressure slides to force the transverse surfaces 13, 14 into welding contact. Figs. 5 and 6 (not shown), indicate modified forms of shouldered lapped joints.

Title: Improvements in or relating to detachable couplings for lubricating apparatus
IPC: F16N21/04
Filed: 1936-01-27
Abstract: 466,614. Lubricator couplings. TECALEMIT, Ltd. Jan. 27, 1936, No. 2590. Convention date, Jan. 28, 1935. [Class 99 (i)] A lubricator coupling 28 is connected to a lubricant - receiving nip ple 50 by a plurality of clamping jaws 36, which are subjected to the com bined action of a spring 38 and the pressure o: the passing lubricant act ing on a piston 40 inter posed between the saic jaws and spring, anc fluid tightness betweer the coupling and nipple is secured by metal seal ing elements 58, 64 which are disposed with in the former in such a manner as to permit considerable angular displacement between the two parts 28, 50. The sealing element 58 is slidable in the piston 40, and is formed with a spherical surface 60 for contact with the dirt-cutting edge 52 of the nipple, and the element 64, which is spring-pressed and is provided with a lubricant passage 68, is slidable in an elastic packing 62 located within a recess at the inner end of the element 58 and terminates in a hemispherical tip to engage the edge 56 of the inlet opening 54 of the nipple. The arrangement is such that, when it is desired to supply lubricant to a nipple, the coupling is pressed against the nipple and the jaws 36 and piston 40 are forced inwardly against the spring 38 a distance sufficient to permit the jaws to clear the head of the nipple, whereupon the spring will force the jaws against a tapering cam surface 34 at the outer end of the coupling and inwardly into engagement with the spherical under-surface 46 of the nipple. The lubricant supply valve is then opened and the action of the spring 38 will be supplemented by the pressure of the lubricant upon the piston 40 to force the jaws more firmly into contact with the nipple ; at the same time this pressure acts upon the upper ends of the elements 58, 64 to force them outwardly into sealing contact with the edges 52, 56 of the nipple respectively. The coupling may be provided with a valve 88 for relieving the pressure therein, if necessary, prior to disconnecting it from the nipple, disconnection of the two parts being effected by tilting them appreciably out of axial alignment, and the valve may carry a wire 94 for cleaning the outlet 70 of the lubricant passage 68.

Title: Improvements relating to electric-bridge measuring arrangements utilising carrier-frequency modulation
IPC: G01R17/00
Filed: 1956-01-30
Abstract: 797,739. Bridge measurements. DAIMLER-BENZ AKT.-GES. Jan. 30, 1956 [Jan. 29, 1955], No. 2960/56. Addition to 760,738. Class 37. In a bridge measurement apparatus for physical quantities of the kind described in the parent Specification the excitation of the interchangeable measuring bridge is derived from a power amplifier excited from an oscillator (which may be crystal controlled) through a coupling transformer and a phaseshift network adjustable to establish correct phase coincidence between the bridge unbalance voltage and the blocking voltage applied to the demodulator, for different interchangeable bridge networks; the blocking voltage also being transformer coupled through a separate power amplifier and a phase-shift network initially adjustable to compensate standing phase shifts in the coupling transformers to the demodulator, which is interchangeably mounted in a thermostatically controlled constant-temperature enclosure. In Fig. 1 an oscillator 1 (which may be crystal controlled) is transformer coupled over phase shift network 2 (Fig. 2, not shown) to negative feedback amplifier 17 coupled over symmetrically wound transformer 18 to the interchangeable measuring bridge B comprising resistive, capacitive, or inductive elements sensitive to physical quantities to be measured. The bridge unbalance voltage is coupled over filter 5, an invariable phase-shift gain control attenuator 6, and cascaded amplifying valves 4, and operates a " magic eye '' tube 7 to assist in bridge balancing, while being transformercoupled to one diagonal of ring rectifier demodulator bridge 10, whose output is coupled through carrier frequency filter 11 to oscillograph O, which is replaceable by a measuring instrument or switching relay. The remaining demodulator diagonal is excited over transformer 3 from amplifier 20, energized from oscillator 1 over phase-shift circuit 21 which is initially preset to compensate for circuit phase shift, while phase shift circuit 2 is predeterminedly adjusted for each interchangeable measuring bridge network so that the measurement voltage and blocking voltage applied to the demodulator are correctly in phase, and the quantity to be measured is indicated by instrument O with maximum sensitivity. The ring demodulator assembly may be contained in a thermostatically controlled enclosure, and may be arranged to be interchangeable (Fig. 3, not shown) together with the output filter and the input transformers for the two diagonals. Plural measuring bridges forming one assembly may be energized from a single oscillator over corresponding separate amplifiers excited from the oscillator.

Title: Improvements in or relating to the manufacture of vinyl esters
Inventor: MAYNE JOHN EDWIN OAKLEY
IPC: C07C67/03
Filed: 1955-02-03
Abstract: Vinyl esters are prepared by a process comprising effecting an ester-interchange between a vinyl ester of a low molecular weight carboxylic acid having 1 to 4 carbon atoms and a carboxylic acid containing 3 to 26 carbon atoms of higher molecular weight by reacting the ester and acid together in the presence of a mercury salt of an aromatic sulphonic acid; preferably, there is used a mercuric salt which, if desired, may be formed in situ from mercuric acetate and the sulphonic acid.  The catalyst may be added in stages and the original vinyl ester is preferably used in excess.  Reaction may be effected at below room temperature up to the boiling point of the reaction mixture but preferably below 60 DEG  C.  Use of the lower temperatures avoids formation of ethylidene diester-type by-products.  Their formation is also reduced by terminating the reaction at the optimum point, for example, by addition of sodium acetate.  Polymerization inhibitors, e.g. copper acetate, may be present.  The resulting esters may be homoor polymerized.  Examples describe ester-interchange between vinyl acetate and capric, caprylic, benzoic, lauric, myristic, adipic, sebacic, behenic, stearic or pyro mellitic acid or distilled linseed oil or dehydrated castor oil fatty acids, the catalyst being mercuric toluene sulphonate or naphthalene-2-sulphonate which sometimes is formed in situ. U.S.A. Specification 2,299,862 is referred to.
