Abstract: 1,030,948. Letting off warfs in beams. LET-OFFS Inc. Nov. 2, 1964, No. 44663/64. Heading D1E. In a positive let-off motion rotation of the warf beam is controlled by tension of the warf acting on a whip roll. A variable diameter pulley 38 on a shaft 30, driven by the main cam shaft, is connected by a drive belt to a similar pulley 39 on a shaft 35, geared to the beam, so that the transmission to the beam may be varied. A flexible cable 67 is connected to the whip roll arm via a shock absorber 71 and is wrapped around and secured to a cam fixed to a weighted lever 49. Tension on the whip roll during let-off raises the lever which moves linkwork 58-66 to vary the diameter of the pulleys so that the rate of rotation of shaft 35 is increased. The cam of the weighted lever may have a spiral face to allow the let-off to compensate automatically for variations in the angle of the warfs over the whip roll.

Title: Improved photosensitive films
IPC: G03C7/30
Filed: 1961-12-19
Abstract: 982,383. Photographic films. EDGERTON, GERMESHAUSEN & GRIER Inc. Dec. 19,1961 [March 24,1961], No. 45388/61. Heading G2C. A photo-sensitive film, characterized by having a wide sensitivity range, comprises a plurality of photo-sensitive emulsions having different and substantially non-overlapping effective sensitivity ranges and each being sensitive to the whole range of electromagnetic radiation to be recorded by the film and means to enable the images appearing in the emulsions respectively, to be separated after development of the emulsions so that the image in each can be printed. Preferably, the different sensitivity ranges slightly overlap so as to produce a continuous effective density-log exposure curve. The images appearing in the emulsions may be separated for printing either by constituting the film as a stripping film in known manner (mechanical separation) or by using colour-couplers (optional separation)-each coupler being different and one being employed in'each of all the emulsions. The colour-couplers are primarycolour absorbing dyes. Printing of the images (in black and white) is then effected using coloured light of appropriate (complementary) spectral composition and panchromatic printing material. Reference is made to the use of colour-couplers in all but one of the emulsions, but in this case no developing process is at present known. The emulsions which are preferably panchromatically sensitized silver halide emulsions may be disposed in separate layers above one another, in thin lines either parallel to or crossing each other or both, in closely disposed squares or dots, on one or both sides of the transparent support or may be mixed to form a single layer. Sensitivity ranges of emulsions may be shifted, if required, by neutral density filters (either in or on one or more emulsion layers), or by using soluble dyes, dye sensitizers or ripening processes. The invention is also said to increase image definition. The invention may be applied to colour photography by recording the three primary colour images separably on different photo-sensitive films, each formed according to the invention. In an example of a two emulsion film the top more sensitive emulsion contains a yellow producing dye and the less sensitive emulsion adjacent the support a magenta producing dye. After developing, the yellow image may be printed using blue light and the magenta image by green light. Alternatively a blue/green filter may be used in the printing of both images simultaneously. In an example of a three emulsion film the top, most sensitive emulsion layer is tinted yellow, the middle one magenta and the lower, least sensitive layer cyan. Printing is effected using blue, green and red light respectively. U. S. A. Specification 3,033,988 is referred to.

Patent GB-461984-A (GB)
Abstract: 461,984. Cash registers. NATIONAL CASH REGISTER CO. Aug. 27, 1935, No. 23962. Convention date, Aug. 30, 1934. [Class 100 (iv)] [Also in Group XIX] Hammer impression arrangements.-In printing mechanism for cash registers and similar accounting machines of the type for printing at will either on a voucher to be issued or on an inserted slip from a single set of type wheels by a single printing hammer, means being provided whereby, during each machine operation, the hammer is given two printing impulses, both impulses being effective with the machine conditioned for voucher printing whilst for slip printing the first only is effective, the second impulse, with the machine conditioned for slip printing, is prevented by locking mechanism automatically operated by the first stroke of the printing hammer. The printing hammer 58, Figs. 1 and 2, receives two impulses at each operation from a cam 67 that serves to stress the spring 65 of a hammer-actuating lever 64. When a hand lever 11 is in its upper position, a voucher is issued and both impulses are effective to cause the hammer to impress the voucher against the type 57. However, upon the adjustment of the lever to its lower position, a shutter 33 is retracted to allow the insertion of a slip in a guideway 34, and a slip feeler 36 is released to control the hammer, permitting one impression if a slip is present and no impression in the absence of a slip. The feeler is guided for vertical movement by studs 39 and is urged upwardly by a spring 45 acting through arms rigid on a shaft 43. In a slip-printing operation, an arm 35, that normally holds the feeler in its lower position, is withdrawn by the hand lever 11, and, after the initiation of the operation, a high-spot 56 on a cam 55 moves away from a roller 53 to allow the feeler to rise and sense the presence or absence of a slip. If no slip is present, the feeler and shaft 43 move to maximum extent and a locking plate 83, Fig. 1, connected to the shaft through an arm 80, pin 81, slot 82 and spring 84, is moved to its dotted line position in which a shoulder 85 on theplate abuts a crank 58<1> of the hammer, whereby the latter is arrested to prevent an impression. If a slip is present, the locking plate 83 is moved by the feeler to the position shown in chain lines and, upon the first upward movement of the hammer, is moved further clockwise to hammerlocking position by the engagement with an arm 86 on the plate, of a stud 87 on the hammer. This movement of the plate occurs just too late to prevent the first impression. However, the plate is retained in locking position by the co-operation of a pawl 88 thereon with a camplate 91 on the shaft and is effective to prevent the second impression. Upon the retraction of the feeler by the cam 55, the parts return to normal position, the pawl 88 being disabled by abutment with a stud 92.

Abstract: 1,059,706. Disc brakes. GENERAL MOTORS CORPORATION. Nov. 4, 1965 [Dec. 7, 1964], No. 46732/65. Heading F2E. A liquid-cooled disc brake comprises a twopart stationary housing 16, 18 forming a closed container for both the braking elements and an impeller for the cooling fluid which is formed integrally with a mounting disc 64 on which the disc 68 is axially slidable, the brake being of the type in which an annular piston 76 is moved to engage the disc 68 which is thereby caused to engage a friction face 78 of the housing. Friction linings 70, 72, which are provided with a system of predominantly radial grooves (108) (Fig. 1, not shown) to enable the cooling fluid, which is oil, to flow past them, are either secured to the disc 68, as shown, or are secured to the piston and housing (Fig. 3, not shown). Automatic wear adjusting means (84) (Fig. 3, not shown) are incorporated in the piston. The disc is axially slidable on splines 66 of the mounting disc 64, the latter having semi-toroidal recesses 92, 94 divided by vanes 96 into series of compartments, these co-operating with similar series of compartments 88, 90 formed in the adjacent walls of the housing to provide a fluid coupling which constitutes the impeller for the fluid. The fluid is thereby driven around a circuit consisting of the impeller, the clearance spaces 100, 102, 104, 106, chamber 58 containing the braking elements, external piping including a reservoir (28) (Fig. 1, not shown) and a heat exchanger (30) (Fig. 1), and the interior of a hub 38 which carries by means of splines 62 the mounting disc 64.
