Abstract: 640,706. Aerials. STANDARD TELEPHONES & CABLES, Ltd. Dec. 19, 1946, No. 37407. Convention date, Jan. 17. [Class 40 (vii)] A radio antenna comprises a hollow cylinder 3 having in its wall a single longitudinal slot 1, 2 with a short circuit at each end, and a feeder 6 coupled to the slot at a point 8 intermediate the short circuits, the crosssectional area of the cylinder being so chosen that the virtual wavelength of the voltage standing wave 11 produced along the slot is approximately twice the corresponding free-space wavelength. The cross-sectional area is less than .0228#<SP>2</SP> with a preferred value between .0154#<SP>2</SP> and .0115#<SP>2</SP>, the distance between short circuits being between A and 3# and the slot width, while not critical, of the order of .023#. When mounted vertically the antenna radiates horizontally polarized waves in a substantially uniform horizontal pattern, the vertical pattern depending on the location of the feed point 8 in relation to the short circuits. In a first condition, that shown in Fig. 1, the feed point is located centrally less than one half the virtual wavelength from each short circuit and results in a circumferential flow of current in phase at all points along the cylinder. The radiation produced has a maximum in the plane perpendicular to the cylinder axis. In a second condition, Fig. 2 (not shown), the feed point is displaced to be distant more than one half the virtual wavelength from one short circuit and less than one half the virtual wavelength from the other. The radiation in this case is in the shape of a bowl with the maximum at an acute angle to the cylinder axis. A third condition is considered, Fig. 3 (not shown), in which the feed point is located between one and one half the virtual wavelength from each short circuit resulting in a maximum of radiation in the plane at right angles to the cylinder together with other lobes which may be major or minor depending on the length of the cylinder. The slot short circuits may be provided by movable bars such as shown at 30 and 31, or plates 4 and 5, closing the cylinder ends. The slot may be closed by an insulating material. Specifications 515,684 and 592,180 are referred to. Reference has been directed by the Comptroller to Specification 635,343.

Abstract: 1,152,198. Missile launch simulator. UNITED STATES OF AMERICA, NAVY, SECRETARY OF. 23 Aug., 1966 [23 Aug., 1965], No. 37852/66. Heading F3C. A missile launch simulator comprises an underwater tube type missile launching system comprising a launching tube 21 within a supporting tube 22 in which the tactical moisture probe is replaced by a dummy moisture probe 44 and dynamic missile simulators 43 are arranged on the missile support ring 24. The missile control center 41 is provided with a dummy triggering inverter unit 42. The missile launching system further comprises a rupturable diaphragm 39 which covers the tube 21 and normally protects a missile from seawater when a hatch 30 of the system is opened. When used as a simulator the missile launching system tube 21 is filled with water 51 equivalent to the weight of an operational missile, the tube 21 being pressurized through a snorted unit 54. On the launching command being generated from the missile control center 41 a departure switch plunger is released by each dynamic simulator 43 to simulate the missiles first motion. The dummy triggering inverter unit 42 transmits a release signal from a launching relay to missile simulator solenoids of the dynamic simulators 43 upon launch command. The diaphragm 39 is then ruptured and the launching tube 21 fills with water to effect post launching conditions. The rupturing of the diaphragm 39 may be delayed by an electrical signal delay located in a box 55 for several simulated firings to give the "ripple" effect caused normally by multiple missile launchings.

Title: Improvements in or relating to sheet transfer mechanisms for sheet-fed rotary printing presses
IPC: B41F21/14
Filed: 1968-08-08
Abstract: 1,222,256. Printing apparatus. SCHNELLPRESSENFABRIK FRANKENTHAL ALBERT & CIE A.G. 8 Aug., 1968 [4 Sept., 1967], No. 37886/68. Heading B6C. In a sheet-fed rotary printing press of the kind in which an impression cylinder has two or more segments and a sheet to be printed on is attached to one segment and printed on with a first ink, then transferred to another segment and printed on with a second ink, registration of the images produced is brought about by displacing the sheet, as required, longitudinally, laterally and rotationally within the apparatus transferring it. Axle 1 carries a drum with grippers mounted on spindle 11 and supports, which co-operate with the grippers to hold a sheet, mounted on spindle 12. The spindles 11, 12 are mounted at each end in a slidable block 25, displaceable as the drum rotates so that the sheet is picked up with its gripped edge in one position relative to the drum and is released with it in another. Movement of the blocks 25 together displaces the sheet longitudinally, differential movement rotates it. Lateral adjustment is by moving the whole drum by action of lever 17 against spring 22, promoted by rotating variable-eccentricity cam 19. Movement of the blocks 25 is brought about by levers 27 which rotate with the drum and carry rollers 33 which run in tracks in displaceable bodies 35, 36. The stroke imposed by these on the levers 27, and so on the blocks 25, is varied by displacing them by action of rotating variable-eccentricity cams similar to 19. Each cam consists of a circular body whose centre is displaceable relative to that of a driving gear-wheel, to an extent decided by the position of the eccentricallymounted head of a bolt in the mount of the gearwheel, adjustable by, for example, a hand wheel.

The head, arms and legs are each movable with respect to the torso and the torso is subdivided into the upper 22 and lower section 24 which are movable with respect to each other. The head 12 has a concave lower surface 265 which fits on to a convex surface 285 at the top of the neck. Union is achieved by means of coupling 32 which has an upper end 34 inside the head joined via rod 37 to ball and socket joint 44 in the neck. Both torso sections are formed of two halves and the upper section is joined to the lower by means of connector 152. The arm, as shown in Fig. 3, is composed of an insert 70 surrounded by flesh-coloured covering 72 of, for example, vinyl plastics. The insert is divided into two parts, upper arm insert 74 and lower arm insert 76, which are joined together by trunnion 110 on the upper arm insert 74 projecting through hole 112 on the lower arm insert 76, hence providing elbow action. The two inserts are kept engaged by means of elbow retainer 80. The upper insert 74 is bifurcated and both portions 86, 88 are bent into hook shape thus providing a bearing for shoulder pin 78, which has a cross portion 90 which rests in the hooks and a stem portion 92 which extends between the bifurcations 86, 88 to the enlarged end 100 through the slot 102 in the covering material 72. The pin is attached to torso bracket 96 which thus provides a bearing about which the arm may describe a complete circle. The lower arm insert 76 has a tubular portion 114 into which fits wrist insert 116. The insert forms at its lower end a disc 128 to which hand 118 is attached by means of trunnions 130, about which the hand may rotate. Wristturning action is provided by means of insert 116 rotating in tube 114. The legs are attached to the lower torso via axle 116 which has a ball 178 which fits the socket 194 on the upper end of upper leg insert 192. Upper leg insert 192 is linked to the lower leg insert 86 by means of trunnion 190 and the hole 192 which permit knee action. The lower end of the lower leg insert 186 has an eight-sided hole 200 which engages with the four sided peg 204 on foot insert 196. This provides means for adjusting the angle of the foot.
