Title: Spring Driven Gyroscope
Inventor: VOGE ANDREW
IPC: G01C19/02
Filed: 1968-03-06
Abstract: 1,188,067. Gyroscopic apparatus. CLARY CORP. March 6, 1968, No. 10918/68. Heading G1C. A gyroscope comprises a cup-shaped rotor 25 mounted for rotation about a spin axis on bearings in a sleeve 22 carried by a cup-shaped inner gimbal member 21, a rotor drive spring 26 coiled inside the rotor, the spring being secured at its outer end 28 to the rotor and coupled to a hook formation 31 on the sleeve 22 at its inner end, the arrangement being such that as the spring unwinds to drive the rotor it coils itself inside the rotor and forms part of the rotary mass thereof, the inner gimbal member 21 being mounted for rotation about an axis b orthogonal to the spin axis in an outer gimbal member 18, the outer gimbal being mounted in turn for rotation on bearings 15, 16 in a base 11 about an axis a orthogonal to the axis b, and a combined caging and latching member 32 engageable with at least the inner gimbal member 21 and a slot 35 in the rotor, the member 32 being releasable in two stages, firstly to release the rotor for rotation to working speed, and subsequently to uncage the gimbal members so that the gyroscope is ready for use. After the spring 26 has become fully unwound and driving the rotor 25 to speed, the inner end thereof disengages the hook formation 31 and is held free thereof by centrifugal force. As the rotor slows down the spring may again engage the hook formation and this feature is useful in testing procedures since the gyroscope driving spring can then be re-wound. The member 32 is shown as extending through a clearance hole 33 in the outer gimbal member 18 but it may positively cage this gimbal also if a suitable slot is provided in place of the hole 33. The member 32 is pivotally mounted at 36 and is held in engagement with the rotor by a pawl 41 which is semicircular in shape and is slidably mounted on a time delay ring 45 in turn rotatable on the base 11 under the action of a spring 46. When it is desired to use the gyroscope a powder squib 48 is fired and the pawl 41 is moved to allow the caging member 32 to move to its chain dotted line position 32a wherein it releases the rotor for rotation, a bent over end (not shown) of the pawl moving to release the ring 45 for rotation on the base 11 under the action of the spring 46. The member 32 is now engaged with the ring 45 and after this has rotated by nearly one complete revolution, a slot in its surface (not shown) allows the member 32 to be moved to the dotted line position 32b to uncage the gimbal members 21, 18. A rim 45a is attached to the ring 45 to increase its inertia during rotation thereof. As an alternative the caging member may be actuated by suitable cam surfaces on the ring 45. A resistive ring 52 with a wiper 53 is provided to act as a pick-off for the relative positions of the gimbal 18 and base 11 about the axis a.

Abstract: 746,435. Cigarettes and cigarette-making machinery. CAPITANI, F. DE. April 15, 1954 [April 15, 1953], No. 11136/54. Class 130. To produce cigarettes having a combustible strip 2a, Fig. 1, inside the cigarette paper 4a and carrying abrasibly ignitable material 3 accessible via a hole 104 in the paper 4a, a machine is employed comprising a punching device 8, Fig. 2, for forming suitably spaced holes in a continuous cigarette paper strip 4, a rotary cutter 15 for severing strips 2a from a corresponding continuous strip having the material 3 along e.g. its centre, and a vacuum conveyer 16 which transfers the severed strips 2a past a glueing device 18 for application to the strip 4 in registration with the holes. The strip 4 subsequently passes to a continuous-rod machine and, according to whether the holes are separated by one or two cigarette lengths, the cigarettes formed thereby are severed adjacent the strips 2a or midway between them and centrally through them as shown in Fig. 1. The punching device 8 may be of a type that burns holes in the strip 4 but as shown is a rotary punch coacting with a spring-loaded die roller 9. Slackadjusting devices 10, 110 consisting of pairs of rollers eccentrically mounted on angularly adjustable discs are positioned between the punch 8 and, on the one hand, a feed roller 5 where the strip 4 is marked with printing by a device 6 and, on the other, a spring-loaded roller 21 against which the conveyer 16 applies the strips 2a to the strip 4, to ensure that the holes do not register with the printing but register with the strips 2a. The conveyer 16 has operative arms 116 having radial bores which connect with a central suction chamber except when their inner ends pass over a stationary baffle plate so placed therein as temporarily to cut off the suction as the arms 116 pass the roller 21.

Filed: 1968-03-08
Abstract: 1,205,129. Cathode materials and processing. RCA CORPORATION. 8 March, 1968 [10 March, 1967], No. 11517/68. Heading H1D. A photocathode comprises in successive layers on an insulating substrate 20, a layer of tin oxide 30, a layer of antimony oxide 34 and a photoemissive layer 32 including antimony which is preferably activated by an alkali metal. The tin oxide layer 30 may be 0À1 to 1À0 microns thick and formed by spraying a solution of tin oxide in alcohol on to a glass support 20 heated to 500‹ C., Fig. 4 (not shown). The antimony oxide layer 34 may be formed by evaporating antimony on to the tin oxide in a vacuum to 100 to 300 A thickness (or until light transmission drops to 50%) and then oxidizing by means of a glow discharge in oxygen at 0À1 to 1À0 torr, Fig. 5 (not shown). Preferably antimony oxide layer 34 is made up of two to five separately formed sublayers. A further non-oxidized coating of antimony is applied over layer 34 prior to incorporating the photocathode in a discharge device, e.g. the proximity focus type image tube shown in Fig. 1. The photocathode mounted in the tube spaced 100 mils. from phosphor screen 27 and secured to re-entrant ring 18 may be activated by successive depositions of potassium and caesium from generators 36. The spacing between re-entrant ring 18 and ring 16 which seals the two cylindrical ceramic envelope portions 12, 14 is made large enough to permit adequate migration of alkali metal from generator 36 into the interelectrode space and at the same time is small enough to protect the generators from the high field, e.g. 15,000 volts, existing between the electrodes.
