Title: Permanent magnetic material which contains rare earth metals especially neodymium and cobalt process for its production and use
IPC: C22C19/07
Filed: 1975-10-30
Abstract: 1479871 Permanent magnet materials BBC BROWN BOVERI & CO Ltd 30 Oct 1975 [14 Jan 1975] 44961/75 Heading C7A A permanent magnet material with the general Formula: - (MM 1-x Md x ) 1-y  Smy Cos wherein 0À25 # x < 1À0, 0 # y < 0À25 and MM is a mixed metal containing Ceα La# Prγ where:- 0À50 < α < 0À70 0À22 < # < 0À45 0À0 < γ < 0À06 and α+#+γ=1 is made by melting stoichochemical proportions of the alloys in BC crucibles in argon in a MF furnace at about 1200‹C. After fusion, the cooled alloys are ground and mixed with powdered sintered additives i.e. Sm40 Co60, so that 10-14% of the total weight of the mixture is the Sm40Co60 additive. The mixture is pressed, magnetically aligned, further isostatically pressed at 600 atmospheres and sintered at 1040‹C prior to heat-treating at 980‹C and cooling in argon or liquid nitrogen. Further annealing at 350‹C is employed. Permanent magnets made by this process and with this composition are said to have a coercitive field strength which is independent of temperature between RT - 300‹C, and are consequently of value as permanent magnets in electric motors.

Abstract: 1520890 Hypodermic injection apparatus MIZZY INC 30 Oct 1975 [23 Jan 1975] 45053/75 Heading A5R A needleless injection apparatus comprises a body 11 having a liquid reservoir 20 from which a predetermined amount of liquid is expelled at high pressure by a piston 21 and discharges through a nozzle assembly comprising a collar 45 mounted on a plug 37 and terminating in a mouth 59, and a nozzle 13 mounted within the collar in spaced relationship thereto and having an orifice 15 connected to a discharge conduit 42, the collar defining a chamber C opening into the mouth 59 and receiving air under pressure from a conduit 61, said air bleeding to atmosphere through mouth 59. A pressure sensing mechanism is operatively connected to conduit 61 and is responsive to a pressure build-up in conduit 61 which occurs when the mouth 59 is sealed against an injection site, to trigger a control assembly (24 not shown) to actuate piston 21 to discharge liquid through the nozzle assembly. Two nozzle assemblies may be provided as shown, the assembly 24 not being triggered unless both collar mouths 59, 59' are sealed against injection sites, injection into both sites then occurring simultaneously. The collar 45 is adjustable on plug 37 so that the pressure with which a nozzle assembly must be pressed against an injection site to effect a seal therewith, to trigger an operative cycle can be varied. Injection liquid is supplied to reservoir 20 through a one-way valve 19 coupled to a liquid supply conduit 18, the reservoir being filled in response to retraction of piston 21 which may be driven by compressed air.

Abstract: 1,260,432. Safety belts. BORG-WARNER CORP. 12 Sept., 1969 [4 Oct., 1968], No. 45226/69. Heading A3V. A safety belt is stored, partially behind panelling 14, in a taut condition by the spring tension in cord 30, which is relieved, during use of the belt, by latch 69. On being withdrawn through a slot in panelling 14, a crossbar 84, carrying the terminal loop 93 of the belt 16, is captured in slots (58), 59 of a bracket (12), secured to the roof 13 of the vehicle and locked therein by the latch 69. After use, the tongue (36) of the belt clasp is hung on hook 34, thereby pivoting member 27 and releasing latch 69, by means of cord 42. The slack is retracted behind the panelling as cord (30) is re-wound on spring drum 26. The ends of cross-bar 84 are guided in flexible elastomeric rails (18), 19. In a modification, the rails are replaced by guide surfaces (101, 102, Fig. 3 not shown), at one or both ends of the travel. In another form, the end of the belt (116, Fig. 4, not shown) is secured to an anchor bar (176), in bracket (112), and is looped around the travelling cross-bar (184).
