Title: Method of copying holograms
Inventor: BRUMM DOUGLAS BRUCE
IPC: G03H1/20
Filed: 1967-11-20
Abstract: 1,207,193. Holography. BATELLE  DEVELOPMENT CORP. Nov.20, 1967 [Nov.30, 1966], No.52696/67. Heading G2J.  A hologram H 5,  Fig.3, is copied by directing an illuminating beam I of monochromatic spatially coherent light onto the recording surface R 5  of the hologram to produce a diffracted image containing beam I 1  and an undiffracted beam Io and using the undiffracted beam I 1  or the illuminating beam I as a reference beam to interfere with the diff-  racted beam I 1  so as to produce an interference pattern on a detecter H 6  spaced from hologram H 5 . As shown H 5  is a front beam hologram and I 1  and I o  interfere to produce a front beam copy. By placing a mirror M as shown the illuminating beam I passes through H 5  and H 6  and is reflected from M as a beam I 2  which interferes with I 1  to produce a back beam copy as well. Arrangements are described for forming front beam or back beam copies or composites thereof from front or back beams holograms.

Abstract: 1314359 Wig making EMMECI-MECCANICA CANZIANI 20 Nov 1970 [20 Nov 1969] 55426/70 Heading A4V [Also in Division D1] A wig support 1 is tufted by a reciprocating hooked needle 3. The latter is pushed through support 1 and engages a running thread of hair 2 issuing from thread guide 6. The needle is retracted to form a loop through the support 1. Projection 5 on rotating disc 4 co-acts with blade 7 to cut the thread. When the needle is below the support the latter is moved through one step and on moving back upwardly the needle re-engages thread 2 and pulls it through the support 1 to form a chain stitch. On every third stitch the projection 5 causes the cutting of the thread to produce two further projecting hairs. In order to maintain tension in the thread a transversely reciprocating bar may be provided between two auxilliary thread guides, Fig. 7 (not shown). In addition a sprung slide (11) may be located before the cutting blade to prevent the rebound of the threads Fig. 10 (not shown).

The post is retained between the lift arms by being mounted on an X-shaped structure consisting of V-members 18, 19, a bottom hub 26 of the post pivoting about a pin 28 extending between the apices of the members 18, 19. Spring-loaded pins 32 engage the hub to prevent rotation thereof about the pin 28 below a predetermined torque applied thereto. The ends of the arms of member 19 are connected to the lift arms by channel members 24 and the ends of member 18 have a shaft 21 connected therebetween into which bolts 23 are screwed through ball trunnions 22 at the ends of arms 11. In a modification the X-shaped structure may be formed from a pair of I-section beams, the post hub being mounted on a pin extending between lugs at the centre of the structure and an additional cross-member thereof, a spring member engaging the bottom of the hub to retain it upright. An alternative means of retaining the post in the channel member 30 may comprise a pivoted gate.

Abstract: 1394457 Wells R R VANN 5 Dec 1972 55975/72 Heading E1F [Also in Division F3] A method in which a lower hydrocarbon zone of a well is completed after an upper hydrocarbon zone of the well has been completed, comprises suspending a packer 20, Fig 1, and a casing perforator 23 on the end of a tubing string 13, positioning the packer and perforator down hole by using the tubing string, forming a fluid flow path from below the packer 20 which communicates with the interior of the tubing string, completing the upper zone, completing the lower zone by actuating the perforator, leaving the perforator downhole, and producing the lower zone through the tubing string and producing the upper zone through an annulus 15 formed between the tubing string and the upper portion of the casing 12. Communication is provided 'between the lower zone and the interior of the tubing string by means of a perforated nipple 21, and by swabbing the interior of the tubing string. The perforator 23 is preferably a casing gun having deep-penetrating shaped charges. The gun-firing mechanism, Fig 2, comprises a firing pin 51, a thin copper wafer 55, an assembly 41 having three bores (54), Fig 6 (not shown), with 22-calibre primers disposed therein, a detonator 39 and primer cord 38. Detonation is achieved by a free-calling weight 45 which shears pins 50 and causes an enlargement 49 to impact the firing pin 51. In an alternative embodiment, Fig 14 (not shown), a shaft (89) comprises two parts joined by a pin (150), and for detonation, the shaft is pulled upwardly by the tubing string against the action of a spring (93) until the pin (150) breaks, and the compressive force of the spring urges the lower part of the shaft downwardly to impact the detonator 39. In further alternative embodiments, Figs 10 and 13 (not shown), the casing gun is electrically actuated by means of a gamma ray tool (60) which is attached to a wire line (62) having a conductor therein. The lower tubing can be isolated by a plug (14'), Fig 8 (not shown), and the tubing string removed form the packer so as to enable completion of the upper zone without the danger of falling debris or inadvertent firing of the gun. Fracturing and acidizing processes may be carried out simultaneously with the firing of the gun.
