Filed: 1975-01-07
Abstract: 1486131 Retractive switches OTTO ENG Inc 7 Jan 1975 [4 Feb 1974] 626/75 Heading H1N A miniature snap-action microswitch comprises an elongated generally planar switch blade 42 having a movable contact portion 44 biased towards one position and having one or more depressed portions 48 bent to lie below the general plane of the blade, the biasing means causing a tensile force tending to straighten the or each depressed portion, and actuating means 56 which moves the or each depressed portion of the blade to cause the contact portion to snap over. As shown the blade comprises a pair of spaced apart legs 45, 46 extending between end portions 43 and 44 and each leg has a depressed portion 48 and a raised portion 49. The biasing means comprises a struck out integral tongue 47 and an opening 52 at each side of the base of the tongue has a diameter at least five times the thickness of the blade.

Title: Rotary solenoid
Inventor: DANILEWICZ LUDOMIR
IPC: H01F7/14
Filed: 1968-01-05
Abstract: 1,244,981. Electromagnetic actuators. ADVANCED DYNAMICS Ltd. 31 March, 1969 [5 Jan., 1968], No. 761/68. Heading H1P. A rotary actuator comprises a stator A including a magnetic circuit with four inwardly extending polepieces 1, 2, 3, 4 separately energized by four coils, and a two-pole armature 5 rotatably mounted in the space between the pole-pieces 1, 2, 3, 4, the poles of the armature 5 being of sufficient width to overlap the faces of the pole-pieces 1, 2, 3, 4 only in the neutral position shown to which the armature is returned by a spring (not shown). When the coils of a pair of opposite polepieces 1, 2; 3, 4 are selectively energized the armature rotates anticlockwise or clockwise until it contacts limit stop 6 or 7. The actuator may be modified by increasing the number of stator polepieces in multiples of four and increasing the number of armature poles by the corresponding multiple of two, to produce a larger torque with corresponding reduction of angle of rotation. The armature may be connected to an output shaft via a ratchet device to produce a bidirectional stepping motor. The stator yoke may be of any tubular form e.g. square, octagonal or round.

Title: Improvements in or relating to heat-exchangers
IPC: F28D7/00
Filed: 1949-01-11
Abstract: 668,376. Tubular heat-exchangers. SOC. L'AIR LIQUIDE, SOC. ANON. POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES G. CLAUDE. Jan. 11, 1949 [Jan. 22, 1948], No. 768/49. Class 64(iii) Relates to tubular heat-exchangers comprising a casing (not shown in the Figure), and a nest of tubes arranged in rows and mounted between two tube plates 3 both of which are fastened to said casing, the tubes being of a metal having a coefficient of expansion different from that of the casing, and each tube being deformed to a wave form for a short distance along its length to allow relative expansion or contraction to take place between the tubes and the casing. According to the invention the magnitude of the wave deflection or deflections (5) is such that when the heatexchanger is operating, the metal of the tubes is under stresses which at least locally, exceed the elastic limit of the metal at the temperature to which it is brought during said operation. The wave deflections 5 which may be of the order of between 3 and 10 centimetres extend for each tube in a direction substantially along the pitch lines of the tube rows with the deflections in one row (e.g. 10-14) of tubes extending in the opposite direction to the deflections in an adjacent row (e.g. 20-23). The tubes may be pre-stressed when assembled to relieve in part the stresses set up in the apparatus due to relative differences in expansion or contraction of the tubes and casing at the working temperature. Spacing strips 4 may be inserted between adjacent rows of tubes.

Abstract: 112,795. Percival, S., (Dallas, C.). Jan. 18, 1917. Sliding-jaw wrenches.-A wrench of the kind in which the sliding jaw is adjusted by means of an externally screwed sleeve on the shank of the fixed jaw engaging an internally screwed tubular extension of the sliding jaw is provided with means for giving a quick adjustment to the sliding jaw. The shank 5 of the fixed jaw 1 is provided with an interrupted screw-thread 6 engaged by threads 7 in a sleeve 12 rotatable in an outer sleeve 10 connected to a screwed part 8 engaging the screwed extension 9 of the movable jaw 4. The sleeve 10 and part 8 are connected by a pin-and-slot connexion 11 permitting a limited relative longitudinal movement so as to grip the sleeve 12 between the end of the part 8 and a shoulder 14 on the sleeve 10, and cause it to rotate with the sleeve 10 to engage or disengage it from the threads 6. The threads 7 are interrupted by solid parts 15, Fig. 2, so that the sleeve 12 has only a limited rotary movement, and the threads 6 and those of the part 8 are of the same pitch. In use, the sleeves 10, 12 are turned together until the threads 6, 7 are disconnected and the sleeves and jaw 4 slid along the shank until the jaws grip the nut. The sleeves are then turned in the opposite direction to re-engage the threads 6, 7 and the sleeve 10 is then turned by itself to tighten the jaw 4 on to the nut. In a modification, the sleeve 10 and part 8 are integrally connected and the sleeve 12 pressed by a spring against the lower end of the part 8.

Patent GB-1062703-A (GB)
Title: Vaccine compositions
IPC: A61K39/145
Filed: 1966-01-07
Abstract: Biological vaccines are concentrated and purified by contacting a virus suspended in an aqueous medium with a particulate magnetic iron oxide, separating the resulting iron oxidevircus vaccine complex from the medium, dissociating this complex and recovering the virus thereby released.  The separation of the complex from the medium may be effected by the application of a magnetic field or by lowspeed centrifugation and the complex may be dissociated by treatment with a saturated aqueous solution of a Na salt of a phosphoric or carbonic acid.  The virus may be cultivated in an aqueous medium containing the iron oxide or the iron oxide is added to the culture medium containing the virus.  The magnetic iron oxide may be in cubic or acicular form and gamma Fe2O3 is preferred.  Viruses which are live as well as inactivated are included and examples of viruses which may be subjected to the process are the rabies, mumps, influenza, parain-influenza, vaccinia, equine encephalomyelitis, canine distemper, poliomyelitis, encephalomycarditis, hog-cholera, St. Louis encephalitis, yellow fever, adenovirus, measles, Coxsackie, ECHO and common cold viruses.  The invention also relates to the intermediate magnetic iron-oxide-virus complex which may be utilized per se without subsequent dissociation.

Title: Manufacture of bottle made of saturated polyester
Inventor: YAMAMOTO KAZUTO
IPC: B29B11/14
Filed: 1991-01-08
Abstract: PURPOSE:To obtain a bottle made of saturated polyester having improved stress- cracking resistance by irradiating the shoulder section of a preform made of saturated polyester with radiation and orienting and blowing the preform. CONSTITUTION:Saturated polyester is molded to a preform 7 through a means such as known injection molding, extrusion molding, etc. Since an oriented section is oriented extremely by a post-process in the preform, it is proper that the length of the preform is molded in size shorter than a conventional preform. The shoulder section of the preform 7 obtained is irradiated with radiation, but it is suitable that radiation is applied while turning the preform as the vertical direction of the preform as an axis. The preform is heated up to an orientation proper temperature, and orientation blowing is conducted, thus acquiring a bottle 1 made of saturated polyester composed of a mouth plug section 2, an upper shoulder section 3, a drum section 5, a lower shoulder section 5 and a bottom 6.
