In a spring mounting particularly for a balance pivot 2 including a spring spider 9 and a bearing element, the spring spider 9 is precompressed and is arranged elastically to centre the bearing element and at the same time elastically to press the latter against a plane sliding surface 4a which extends perpendicularly to the staff 1 having the pivot 2, the staff 1 extending through the surface 4a. The bearing comprises a pierced stone 7 fixed in a bouchon 6, and an end stone 8 which is held in the bouchon 6 by spring tongues 9b which extend inwardly from the annular portion 9a of the spider 9 through slots provided in the wall 6c of the bouchon 6. The base 6b of the bouchon 6 is arranged to slide on the surface 4a of the housing 4. The annular portion 9a of the spring spider 9 surrounds the wall 6c of the bouchon 6, and three arms 9c extend from the portion 9 and bear against a recessed portion 4c in the housing 4. Projections 9d on the arms 9c engage recesses 4d in the portion 4c and locate the spring spider axially. Recesses 4f in the wall 4c facilitate assembly of the spring.

Title: Oriented straps and their preparation

Filed: 1970-07-07
Abstract: 1293033 Straps EI DU PONT DE NEMOURS & CO 7 July 1970 [29 July 1969] 33020/70 Heading A4X [Also in Division B5] An oriented strap, e.g. for binding containers, wrapping pipes, or adhesive tape, is formed of at least 75 weight per cent polyethylene of density of at least 0À95 g per cc and of melt index from 0À2 to 1À0 and is of uniform cross-section along its length, and has an angular width at the one-half maximum corresponding to the tilting of the polymer chains from the longitudinal direction toward the transverse direction of less than 7 degrees when determined by X ray diffraction analysis. In the process for forming the strap, pellets are fed into a hopper 2 and extruded through a head 3 into a quench bath 4. The billet so formed is drawn out of the bath 4 by rollers 7 and 8. The billet is then fed through one or more pairs of orientating rollers 12, 13 and tension rollers 14, 15 with a skew roller 16, before it is passed to a hot oil stretching bath 17 having rollers 18 to 20. After the bath 17, the billet is passed via tension rollers 21, 22 and a skew roller 23 to a heat conditioner 24, a wash tank 26, and finally to a spool 27. The polyethylene used for the strap may be blended with a low density polyethylene, an ethylene/vinyl acetate copolymer, methylene/ methacrylic acid copolymer, an ethylene/vinyl acetate/ methacrylic acid terpolymer, isotactic polypropylene or moldable styrene/butadiene rubber. The largest melting peak of the strap when measured by differential thermal analysis at a rate of 10C. per min is from 140 to 145C.

Filed: 1973-07-13
Abstract: 1433056 Orientating articles PNEUMATIC SCALE CORP 13 July 1973 [10 Oct 1972 23 April 1973] 33579/73 Heading B8S Elongate plastic bottles 12 lying on their sides are delivered to an orientating apparatus with their open ends either leading or trailing and are oriented into an upright position with their open ends uppermost by passing the bottles along a rail 62 which supports the bottles at mid-length allowing the heavier closed bottoms of the bottles to gravitate and pivot the bottles about the rail 62 into the upright position. The bottles are delivered successively down a shoot 10 into a magazine 14 where they form a stack, successive lowermost bottles in the stack being deposited into spaced radially extending pockets 16 of a rotary disc 18 as the latter is rotated to pass the pockets below the magazine. Each bottle dropping into the pocket 16 is initially supported on a stationary support disposed adjacent the open bottom of the pocket, and with rotation of the disc 18 and hence pocket 16, the radially disposed bottle is moved along the stationary support on to the rail 62. Air jets 56 are provided to urge the stack of bottles in the magazine downwardly to assist transfer of the lowermost bottle. The bottles supported only on the rail 62, gravitate into an upright position either radially inwardly or outwardly of the rail 62 depending on their positions in the pockets, into radially inner or outer pathways 22, 20 formed on a stationary base 44 below the disc 18, the two pathways merging into one for directing a single line of bottles on to discharge conveyers 26. The pathways 20, 22 progressively narrow in the direction of bottle travel to guide the bottles from inclined to fully upright positions. Rocking of the bottles about the rail 62 is assisted firstly by bottle engaging fingers 27 and then by air jets 64, 66 directed from above the bottles. The apparatus is automatically controlled by two photo-electric detecting mechanisms, one being located adjacent a feeding mechanism for the apparatus and the other 47, 49 being located adjacent the feed shoot, the disc 18 being maintained in operation provided bottles are detected by the mechanism 47, 49 and the feeding mechanism being stopped if the bottles are detected backing up as far as the mechanism. In the modified apparatus of Figs. 11, 12, 13 (not shown) the stack of bottles in the magazine are urged downwardly by a spring loaded floatingly mounted driven rubber covered wheel. In the embodiment of Figs. 14 to 18 (not shown) the bottles are transferred from a horizontal delivery shoot by air pressure, into pockets in a drum rotatable about an horizontal axis, whereafter the pockets rotate into alignment with the bottle receiving pockets on the orienting disc. In a further embodiment of Figs. 19 to 22 (not shown) the bottles are blown singly into a receiver from which each bottle is pushed downwardly into a pocket in the orienting disc by an air operated pusher foot operated in sequence with the disc movement.

Title: Light modulator
IPC: G02F1/03
Filed: 1965-08-05
Abstract: 1,072,500. Modulating light. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 5, 1965 [Aug. 25, 1964], No. 33582/65. Heading H4F. A polarization light modulator comprises a crystal structure 18 including three layers 18a- 18c of electro-optic material positioned between crossed polarizers 10 and 11 in a resonant cavity 6 in which an electric field E in the form of a standing wave is set up. Each layer occupies the whole or part of the thickness of a different region having a thickness equal to the distance travelled by the monochromatic light beam 5 during one half-cycle of the field, the light beam passing through the layers sequentially. The layers are arranged with their optic axes parallel and when the material of the layers is KDP the centre layer 18b is angularly displaced by 90 degrees about the optic axes with respect to the other layers so that one of the components of the elliptically polarized light produced by the layers in response to the field is cumulatively delayed as the light beam propagates through the layers. In actual fact adjacent layers delay different components of the elliptically polarized light in response to the same field but because the actual thickness, in the embodiment described, of each layer is equal to the distance the light wave propagates during one half-cycle of the modulating field and because layer 18b is displaced 90 degrees about the optic axes, the same component of the elliptically polarized light is delayed. Thus the changes in polarity of the modulating field which occur while a light wave is propagating through the layers of material is compensated for by the orientation of the layers. In this manner the depth of modulation may be increased especially where the modulating signal is in the microwave frequency range. The field need not be a standing wave but could be any oscillating field such as a travelling wave. Further, instead of an electric field a magnetic or acoustic field may be used, and the light need not be plane polarized when entering layer 18a. Zinc sulphide in the cubic phase may be employed instead of KDP in which case the orientation of layer 18b will be in some way other than 90 degrees about the optic axis. A detailed description of the operation of the layers is given in the Specification with respect to Fig. 3, not shown. The band width of the modulator may be increased at the expense of modulation depth by slightly increasing the thickness of one or more of the layers and slightly decreasing the thickness of the remaining layers. The modulator is then capable of accommodating fields havnig a wider range of frequencies.
