Title: Improvements in and relating to the brazing and soldering of nickel and nickel-base alloys
Inventor: SLOBODA MIECZYSLAW HERMAN
IPC: B23K35/34
Filed: 1960-06-27
Abstract: In a method of soldering on brazing nickel or nickel base alloys the boron and fluorine containing type flux has copper or a copper compound (oxide or chloride) added.  The stated range is 0.1-3% which is sufficient to deposit a layer of copper but not to interfere with the characteristics of the flux.  This addition prevents the occurrence of cracking due to grain boundary embrittlement which occurs with prior art fluxes.  The Provisional Specification discloses the use of Sn, Au, Ag, Pd, p  Pt, or any other metal above nickel in the electrochemical series, as an alternative or in addition to copper.  This matter does not appear in the Specification as accepted.
Patent GB-154009-A (GB)
Title: Improvements in and relating to submarine sound signalling apparatus and the like
IPC: G01S1/72
Filed: 1919-09-12
Abstract: 154,009. Wall, T. F. Sept. 12, 1919. Addition to 126,654. Detecting subaqueous sounds.-The apparatus referred to in the parent Specification for transmitting subaqueous sound signals is adapted for use as a receiver of such signals. In addition to the coils and blocks of stampings used for transmitting, separate and distinct electric and magnetic circuits are provided, this arrangement having the advantage that each system may be designed most efficiently for its own purpose. A block of stampings g is fixed to the frame h of the oscillator and a second block k is secured by means of a distance piece p and a support m to the diaphragm n, the two blocks being thus separated by a small air gap. An exciting-coil a wound on the fixed stampings is connected to a secondary battery e and through a transformer to a telephone receiver d, either as in Fig. 1 in which a second coil b in series with a forms the primary, or as in Fig. 2 in which a itself is the primary. In the latter case, the secondary coil f is wound by the side of the exciting-coil a. Sound waves impinging on the diaphragm n produce variations in the width of the air space and consequently variations in the magnetic flux linked up with the exciting-coil. This causes pulsations of induced voltage in the coil a, which are transmitted to the telephone d as audible signals. Instead of connecting the telephone directly to the secondary of the transformer, any amplifying device may be used to magnify the signals. The secondary circuit can also be tuned to resound to any particular frequency desired.

Abstract: 615,139. Clocks. BOXWELL, C. F. N. July 29, 1946, No. 22456. [Class 139] A clock regulated or controlled by a conical pendulum in which the pendulum bob is restricted to a predetermined circular path by stabilizing its circumferential velocity by frictional interaction between the bob and an annular control ring placed in the horizontal plane of movement of the centre of the bob. As shown in Fig. 1, the pendulum bob P is formed with an annular groove in which are provided soft brush hairs, not shown, which frictionally engage the surface of the annular control ring C and cause dissipation of any surplus energy to restrict the bob to its predetermined path. The foot of the pendulum engages a rotor bar R driven by wheelwork W which drives the hands over an inclined dial D. The pendulum bob may have a permanent magnet core M, Fig. 4, which carries two cylindrical members P, P, of magnetic material provided with opposed pole-pieces which magnetically co-operate with the annular control ring C, Fig. 5 to induce therein friction in the form of eddy currents and so dissipate any surplus energy and restrict the bob to its predetermined path. The pendulum is mounted at the top in such a way as to provide temperature compensation.

Title: Olefine copolymers
Inventor: CLARK KEITH JASPER
IPC: C08F10/00
Filed: 1964-06-01
Abstract: A solid crystalline copolymer of butene-1 containing a minor amount by weight of a branched 1-olefine comonomer, said branched 1-olefine comonomer having at least six carbon atoms and having a linear chain containing at least four but not more than eight carbon atoms, said linear chain being substituted in any one or more of the 3, 4, 5, 6 or 7 positions by a methyl or ethyl group, said copolymer having a crystalline form substantially identical with the Type II crystalline form of the butene-1 homopolymer the copolymer being substantially more stable in said crystalline form than is a butene-1 homopolymer in the Type II crystalline form, may be prepared using a stereospecific catalyst comprising a transition metal compound and an organometallic activator. Preferably, 10 to 40% by weight of the branched 1-olefine comonomer is used.  The copolymerization is preferably carried out under conditions such that a slurry is formed, e.g. by using a polymerization catalyst which has previously been contacted with 10 to 1000% of the weight of the catalyst of a 1-olefine, so that a small degree of polymerization has already taken place.  In the examples, butene-1 is copolymerized with 4-methyl pentene-1 or 3-methyl-pentene-1 or 3-methyl hexene-1 or 5,5-dimethyl hexene-1 or 3-ethyl-pentene-1, the catalyst being selected from (a) TiCl3 which has previously been treated with 3-methyl butene-1, and aluminium diethyl chloride; (b) TiCl3 pretreated with propylene, and aluminium diethyl chloride and (c) TiCl3 and diethyl aluminium chloride.  The copolymers produced may be transparent, i.e. have a light transmission as measured by ASTM Test 1784-62T of greater than 40% when measured in 1/8 -inch section.
