Title: Toggle type clamping mechanisms
IPC: B29C45/17
Filed: 1963-12-31
Abstract: 982,000. Linkwork; screw-and-nut gearing. IMPROVED MACHINERY Inc. Dec. 31, 1963 [Jan. 10, 1963], No. 51312/63. Headings F2K and F2Q. [Also in Divisions B3 and B5] In a toggle press, tie-rods 34, 36 carry at one end a crosshead 42, at the other end an outboard platen 38, and, slidably mounted between them, an inboard platen 44, and pairs of toggle arms 54, 56 are pivoted to the cross-head 42, pairs of toggle arms 48, 50 are pivoted to the inboard platen 44, and the four pairs of toggle arms are pivotally connected together at their inner ends in a centre block 60. The tie-rods 34, 36 are slidably mounted in bearing blocks 28, 30 carried by the machine frame. The block 60 is connected to a piston rod 72 of an hydraulic cylinder 70 which is carried by a yoke 68 supported by arms 64, 66 pivotally connected to the outer ends of the toggle arms, as shown in Fig. 2. On the supply of fluid to the cylinder 70, the block 60 is moved upwardly causing the toggle arms to straighten out and thereby cause the platens 38, 44 to approach each other. The axial position of the cross-head 42 on the tie-rods 34, 36 is adjustable, in order to vary the position of outboard platen 38 with respect to inboard platen 44, by simultaneous rotation of nuts 76, 78 threaded on to the tierods and bearing against the outer face of the cross-head. The nuts 76, 78 have sprocket teeth on their peripheries over which passes a chain 88, which also passes around a central idler sprocket 90 and a driving sprocket 92 having a crank-receiving projection 96. Locking bars 80, 82 are pivotally secured to the cross-head 42, and are adapted to lock the nuts 76, 78 on tightening of bolts 84, 86.

Title: Optical cavity structure for a laser
IPC: H01S3/097
Filed: 1973-11-06
Abstract: 1444404 Lasers AVCO CORP 6 Nov 1973 [21 Nov 1972] 51447/73 Heading H1C To maintain accurate alignment of resonator mirrors when the supporting structure becomes heated during laser operation, the mirrors 32, 38, Fig. 3, are mounted on end blocks 25, 26 which are spatially supported by spacer rods 27-30 Fig. 4, of low thermal expansion coefficient, thermal gradients developed in the rods due to poor conduction being removed by copper sheaths 51-54 coupled to a circulated coolant in ducts 71a-74a. The active medium in the laser described is a CO 2 -N 2 -He mixture circulated by a blower 22 and ducting 16 so as to flow in direction 80 transversely of the resonator. Pumping is effected by the combination of an electron beam from a beam generator system 9, and an electric discharge between electrodes 14, 15, one wall 21 bounding the discharge region consisting of foil transparent to the electron beam. Copper sheath expansion is absorbed by securing sheath flanges such as 55, 57 to end block 25 and permitting floating movement of opposite end flanges such as 61, 63 along studs 65 in end block 26. Apertured copper shields 66, 67 thermally screen the end blocks. Each resonator mirror 32, 38 is mounted on a respective support 33, 42 and has tilt adjustment provided by a three point mounting consisting of a pivot such as 35 and electric positioning motors 36, 37. The laser output is obtained by resonator spill from an adjustable annular mirror 39, the output beam passing through an end block aperture and an aerodynamic window 41 in an outer casing 1, Fig. 1. Mirror 38 adjustment is obtained by a three point mounting consisting of a pivot 43 and positioning motors 44, 45. A similar adjustment arrangement is provided for mirror 39. The resonator assembly is supported by two pedestals 102, 108 joined by a massive member 121, relative movement between the assembly and pedestals due to temperature changes being permitted by a three point support which consists of domed threaded pads 91 engaging angled grooves in the end blocks, Figs. 6 and 7 (not shown). The coupled pedestals are themselves mounted for relative movement on a mechanical ground by a three point suspension of which two points each consist of a ball between facing angled grooves, Figs. 11-13 (not shown).

Abstract: 515,540. Modifying metallic surfaces; pickling; silvering. GILBERT, W. V. June 3, 1938, Nos. 16620/38, 10592/39, and 16089/39. [Class 82 (ii)] [Also in Groups VIII and V] Metals are protected against corrosion and decay by applying thereto a chromate dissolved in a volatile alkali solvent consisting of aqueous ammonia with or without a small addition of acetone, ethyl alcohol or diacetone alcohol. Specified chromates are those of cadmium, cobalt, copper, silver and zinc. A wetting- agent, e.g. a sulphonated alcohol or sulphonated dicarboxylic aliphatic acid, may be added, also copper arsenate or arsenite or zinc arsenite. The surface to be treated may be roughened to secure better adhesion, i.e. metal surfaces may be anodized, shot-blasted, etched, metallized &c. Metal surfaces are prepared for treatment by removing grease, oil or loose rust. When employing silver chromate, the surface may be exposed to actinic light to reduce part of the salt to metallic silver; filter cloths so treated have improved filtering properties. The protective chromate layer may be coated with varnish, paint, enamel &c.

Title: Improvements in bundling machines
IPC: B65B13/28
Filed: 1966-11-22
Abstract: 1,100,507. Twisting wires together. SUNDSVALLS VERKSTADER A.B. 22 Nov., 1966, No. 52158/66. Heading B3E. [Also in Division B8] In a machine for bundling e.g. bars or coiled metal wires by binding with e.g. iron wires, of the type having an acouate wire guide path 3, part of which pivots outwards to admit the articles to be bound, a twisting head 51, and a cutter 60, the wire feeding mechanism includes a feed wheel 71 and a device sensing the raising of the wire 15 from the periphery of wheel 71 when sufficient wire has been fed. The sensing device causes several of the feed wheel 71 to. tighten the wire around the bundle, the wire end having been locked by a plunger 59. As described, one of the halves e.g. 3a of the guide path is swingeable to an open position. The. wire. feeding mechanism comprises a wire supply (not shown), rolls 79 which press down the wire 15 into a groove (72), Fig. 3 (not shown), in the wire feed wheel 71, and a wire guide 41. The sensing device includes a roll 76 mounted on a pivotable arm 74 and contacting the wire which actuates a limit switch 80 when the wire begins to deflect at the termination of feeding. A further limit switch 84 may be provided so that if the wire is pulled out of the twisting head so that the roll 76 no longer sustained by the wire drops on to the wheel periphery, the reversal of the feed wheel 71 is stopped. The twisting head 51, Fig. 5, see also Figs. 2-4 (not shown), includes two grooves 52, 53 for the wire arranged on either side of the plane of the wire guide 3 when in the starting position. A plunger 59 is provided to bend over clamp the forward end of the fed wire 15, Fig. 5a, and to act as a stop to terminate the feeding by causing the wire to rise from the wheel 71 as described above. A plunger 92 may ride in cam groove (91), Fig. 3, so that in its radially outermost position it actuates an electrical counter (not shown) to stop the twisting head rotating. To re-set the twisting head it is rotated in the opposite sense until an abutment in groove (91) engages plunger 92 to stop rotation. If the head is hydraulically driven the resulting fluid pressure increase actuates a switch to stop the drive. The twisting action is of the type where a motor 56 rotates a fly-wheel 55 through approximately one revolution whereupon it engages the twisting head 51 through a claw coupling (54), Fig. 4, the impact causing the wire to enter a notch 52a shearing off this portion against a cutter 60, Fig. 5b, and rotation proceeding for a given number of revolutions or until the wire ends slide out of the twisting head 51.

The reaction may be carried out with a sulphuric acid or phosphoric acid derivative in which one or two acid hydroxy groups are blocked, the protective groups subsequently being removed from the resultant esters by hydrolysis or hydrogenolysis. Also any groups in the hydroxy flavanoid which might react with the esterifying agent may be blocked by protective groups which can be removed after esterification, e.g. by hydrolysis or hydrogenolysis.  The compounds may be converted to the corresponding physiologically compatible salts by treatment with an inorganic or organic base.  Therapeutic compositions, having cholesterol level lowering properties and oestrogenic, ovary - stimulating, antispasmodic and/or cardioactive properties, contain as active ingredient the above sulphuric or phosphoric flavanoid esters or their salts. The composition may be in a form suitable for parenteral, enteral or topical application.
