Title: Arrangement for braking the warp beam on looms
IPC: D03D49/08
Filed: 1951-07-26
Abstract: 708,289. Loom warp beam braking dervices. FISCHER AKT.-GES.. G. July 26. 1951 [Aug. 3, 1950], No. 17783/51. Class 142(2) The braking effect of shoes 6, 9 due to a compression spring 22, is relieved as the warp diameter diminishes, by a feeler 42 reducing the spring compression. The, feeler pivots about the axis of a rod 38, to which it is secured, and the rod carries an arm 36 having a pivot 35 adjustable in a slot 45 by a screw 49. The pivot 35 supports a rod 30 connected to the means compressing the spring. The spring compression is also variable for different warps by a wing nut 23. Different springs 22 may be fitted for different warp threads. A toggle 19 permits quick release of the, brake. The feeler motion may be transmitted by a cam 59 mounted on the shaft, 38 acting on a follower 57 on the shaft 30. With this arrangement the cam 59 would have to be changed with the spring.

Title: Improvements in stereoscopic photography
IPC: G03B35/00
Filed: 1933-06-22
Abstract: 409,526. Stereoscopic kinematography. P. D. Inc., 1417, Spruce Street, Philadelphia, U.S.A.-(Assignees of Brock, N. H. ; 1417, Spruce Street, Philadelphia, U.S.A.) June 22, 1933, Nos. 17855 and 17856. Convention dates, June 30, 1932 and Feb. 6, 1933. [Class 97 (i).] In stereoscopic kinematography in which different view point pictures are adapted to be projected in rapid alternation on a screen, the separation of the view points is a small fraction of the interpupilar distance. A tracking adjustment is made, either when taking the negative by laterally shifting the film gate or when printing positives therefrom, to bring the images taken from one view point into alignment with those taken from the other. Such adjustment can only correct for the lateral shift of images of objects in a single plane parallel to the film. If this plane be suitably chosen between the extreme foreground and background planes the maximum lateral shift on the film of the different view point images of any object may, with a view point separation of a fraction of an inch, e.g. 3/10 in., be kept small enough to obviate noticeable flicker of any part of the projected picture. Normally the optical paths from an object to the film are of different lengths for the different view point images and a scale adjustment of one set of view point images is necessary. This adjustment and the tracking adjustment may be made simultaneously when printing, one set of view point images being printed on the positive film with intermediate spaces which subsequently receive the other set of view point images after movement of the projecting lens. Fig. 1 shows a camera A for taking the stereoscopic pictures. The driving shaft A<2> is connected through gearing A<7>, A<8>, A<10> to a disc BC<1>, which rotates in synchronism with the camera mechanism in a plane making an angle of 45‹ with its optical axis. A pair of reflectors B, made of magnetic stainless steel or the material known under the Registered Trade Mark " Stellite " and mounted on the disc BC<1> parallel therewith, are adapted to reflect one set of view point images into the camera objective A<1> whilst a similar mounted pair of reflectors C reflect the other set. The view point separation is effected by the interposition of suitable shims BC<3> between disc BC<1> and reflectors C.

Title: Instrument for measuring holes
IPC: G01B5/08
Filed: 1956-06-11
Abstract: 819,970. Linear-dimension gauges. JOHANSSON A.B., C. E. June 11, 1956 [June 13, 1955], No. 18002/56. Class 106 (2). In a bore measuring instrument a moving plunger 9 acting on balls or small rods adapted as feelers has two diametrically opposed grooves 18 of angular cross-section and at an angle to the axis of the plunger and each acting on one of the two balls or rods which lie in guides formed by coaxial holes in the end of the body of the instrument, with their common axis perpendicular to the axis of the instrument. The instrument has a sleeve 2 provided with an internal thread into which screws a second sleeve 3 held in position by a lock-nut 4. At the other end of the sleeve 3 are two coaxial radial holes 5 containing the balls 7. The plunger 9 slides inside the sleeves and is allowed a small amount of transverse play therein. The ends of the plunger act on the balls 7 and the stem 11 of a dial gauge 1 respectively. The end of the plunger 9 which acts on the balls has two diametrically opposed grooves 18 (Fig. 2) of angular cross-section, whilst the other end 19 is in the form of a hemisphere with there bevel surfaces cut on it which are equally spaced but do not meet and so leave three sections of the sphere at 120 degrees to one another. The end of the stem 11 is a cone and so there are always three points in contact, on the circle of contact of the sphere and the cone, between the stem 11 and the plunger 9 which thus can pivot about this end. A hollow screw 16 fits in the end of sleeve 3 as shown and allows the plunger 9 to move transversely whilst a shoulder 15 and two nuts 17 on the plunger 9 prevent it from moving too far axially by acting against the screw 16. The balls 7 are prevented from dropping out of the grooves by a slotted resilient ring 20. The balls 7 may be replaced by cylinders, preferably with rounded ends and the holes 5 may be adapted to touch the balls or cylinders only at two points or along two lines respectively, by forming the cross-sections of holes in the form either of a circle and two tangents to it or of a circle and a flute on one side of it in the form of a smaller circle.

Title: Improved Cigarette Dense End Measuring and Controlling Apparatus
Inventor: NORWICH ALAN
IPC: A24C5/18
Filed: 1967-04-20
Abstract: 1,190,822. Cigarette-making machine. INDUSTRIAL NUCLEONICS CORP. 20 April, 1967 [20 April, 1966], No. 18336/67. Heading A2C. [Also in Divisions G1 and G3] The operation of a machine for producing cigarettes having dense ends, said machine forming a continuous tobacco rod 18 containing extra tobacco in locally dense regions R spaced along its length and conveying said rod 18 along a path including the location of a cutter 20 adapted to cut through each of said dense regions R to form cigarettes 22 with dense ends, is monitored by an apparatus comprising means for measuring the density of the rod 18 as it passes a predetermined position along said path to produce successive signals each representative of successive dense regions in the rod 18, means for generating a reference signal in response to each operation of the cutter 20, and means for providing an indication of the phase relationship between the reference signals and the successive dense region signals to provide thereby an indication of the deviation of the dense regions R from the ends of the cut cigarettes 22. The density of the continuous rod 18 is measured by a gauge 30, of the radiation or capacitance type, which is placed as close as possible to the cutter 20. A reference pulse generator 32 is mechanically coupled to the cutter 20, and may comprise either an electrical switch contact or a rotating reflective strip from which a light beam is reflected on to a phototransistor detector. Where the spacing between the cutter 20 and the gauge 30 is not an integral number of cigarette lengths, the reference pulses are passed through a delay device 36 before being fed to a phase comparator 38. This comparator 30 (a circuit for which is disclosed) compares the reference signals with the signals from the gauge 30 to produce an output signal directly proportional to, and indicating the direction of, any deviation in the dense regions R from the ends of the cut cigarettes 22. A motor 26 drives the cutter 20 and a known type of denseending device 24 via a differential 48 which may be adjusted, either automatically by a controller 46 or manually, in response to deviations from zero in the output signal of the phase comparator 38 as shown by a meter 40. In a modification, a switching arrangement is provided to permit the apparatus to be used also to monitor changes in density of the dense end region R.
