Abstract: 1,191,764. Making holograms. HOLOTRON CORP. April 8, 1968 [April 12, 1967], No.16867/68. Headings G2C and G2J. In a method of producing a multiple hologram, from which a contoured image of an object can be reconstructed, wherein the object is successively illuminated with coherent radiation from at least two apparent source positions P 1 , P 2  respectively and the multiple hologram H formed with light reflected from the object O and light from a reference beam R of radiation coherent with the radiation from the two apparent sources, a refractive means (e.g. a refractor plate) RP is interposed in a beam of actual radiation directed toward the object to give apparent source P 1 , and the means RP is then reoriented at a different angular position with respect to said beam of coherent radiation to give the second apparent source P 2 , the apparent sources P 1 , P 2  being at relatively small angular displacements with respect to the object, the angle of reorientation being relatively large as compared to the angular displacement between the apparent sources. Preferably the refractor plate RP is oriented and reoriented at equal angles Ï 1 , Ï 2  oppositely directed from a plane perpendicular to the direction of the beam. The spacings of the contour lines can be preselected to desired values as a function of the refractive index of plate RP, the thickness of the plate and the angles of orientation Ï.

Title: Improvements in or relating to means for feeding fabric or other webs
IPC: D03D49/20
Filed: 1937-06-18
Abstract: 497,363. Loom take-up motions. TEFAG TEXTIL-FINANZ AKT.-GES. June 18, 1937, No. 16972. Convention date, Aug. 1, 1936. [Class 142 (ii)] [Also in Group XVI] A web-feeding device which is especially applicable to the take-up motion of a loom is constructed with means for adjusting the speed of take-up comprising two feed gears each adjustable in steps to vary the feed and so interconnected that their effects may be added or subtracted, the arrangement being such that the complete range of adjustment of the fine feed corresponds approximately to one step in the adjustment of the coarse feed. The two feeds, Fig. 1, are operated by oscillating levers 5, 6 operated by cranks 1, 2 rotating in opposite directions the levers being fitted with pawls 7, 8 which actuate ratchet wheels 9, 10. The wheel 10 has a shaft 12 which drives a wheel 16 through a free-wheel clutch, and the wheel 16 is geared to a wheel 14 for operating the web feed device. The wheel 9 is geared directly to the wheel 16 and effects the fine adjustment of the feed. The actual adjustments of both the fine and coarse feeds are obtained by adjusting the point of connection of the connecting-rods 3, 4 with the levers 5, 6 by operating screws 5<1>, 6<1>, which cause the pivots 17, 18 to move in slots in the levers and thus vary the throw of the pawls 7, 8. In a modification the adjustment of the fine feed is obtained by varying the phase of the cranks 1, 2 in order to vary the effective length of the stroke of the lever 5. If this lever is in exact phase with the lever 6 it has no effect on the feed. In a further modification, Figs. 4 and 5, a pair of concentric ratchet wheels 47, 48 are operated by adjustable crank-and-lever mechanism 32, 33, 34, 35, 36, 41, 42 by means of which throws of variable lengths are given to levers 43, 44 with pawls 45, 46 for operating the ratchet wheels 47, 48. These levers and pawls may be arranged to rotate the wheels 47, 48 in opposite directions, so that the fine feed may be subtracted from the coarse feed. The wheels 47, 48 are connected to the feed shaft 50 by planetary gearing comprising two pairs of planet wheels 49 carried from the disc 47 by stub axles 59 and engaging a wheel 51 fixed to the shaft 50 and a wheel 52 rigid with the disc 48. The adjustment of the feed may be effected by hand, or the fine adjustment device may be controlled automatically by a governor, or by an arm 57 controlled by the diameter of the cloth beam.

Title: Improvements in electrical ignition systems
IPC: F02P3/08
Filed: 1947-07-02
Abstract: 624,325. Ignition systems. BRITISH THOMSON-HOUSTON CO., Ltd., WELCH, D. F., and GRIEVE, A. July 2, 1947, No. 17476. [Class 7 (iv)] In an ignition system in which a high frequency discharge at a sparking plug is obtained by intermittently charging a condenser C1 and discharging it through a spark gap, the condenser is provided with a pair of discharge gaps connected in series therewith the breakdown voltage of one of them G2 in Fig. L or G 1 in Fig. 2 being of the order of and preferably just greater than the maximum value of the generated voltage applied to the condenser and the breakdown voltage of the other gap being of the order of half that of the first mentioned gap, the gaps being caused to break down by applying to the common connection between them, which connection is maintained substantially at the generated voltage (Fig. 1) or at zero potential (Fig. 2) an initiation voltage obtained by a peaking transformer Tp or peaking choke Chp energised by the charging current flowing into the condenser. The choke and the transformer are arranged to be saturated at a given value of the charging current and thus give a peak when the charging current falls to zero at peak voltage on the condenser. The voltage peak in the system of Fig. 1 causes the breakdown of the gap G2 and thus brings the full voltage of the condenser across the gap G1, which then ruptures. In Fig. 2 the voltage peak from the choke is fed to. the gap junction by a condenser G2. The value of a resistance R is chosen so that when taken in conjunction with the capacity C2 the relatively slow rise of generated voltage across S1 should result in little or no voltage appearing across G2 while the rapidly applied voltage from the peaking choke should appear across G 1 with the minimum of loss. The gap G1 is supplied by the voltage across Sl and R, the impedance of Chp being zero while it is saturated. When the voltage peak occurs due to the fall to zero of the charging current the gap G1 is ruptured first causing breakdown of gap G2. The spark gaps may be of the hermetically sealed type and enclosed in a single sealed envelope with an intermediate electrode forming a common electrode of the two gaps. Specifications 525,492, 529,458, 529,558, 545,857 and 598,053 are referred to.
