Filed: 1962-04-09
Abstract: 1,002,284. Rotary conveyers. CROWN CORK & SEAL CO. Inc. April 9, 1962, No. 13597/62. Heading B8A. [Also in Division G1]  In photo-electric apparatus used for inspecting the contents of bottles B for the presence of foreign bodies, the bottles are taken from a conveyer line by a star-wheel 19 and placed on bottle cups 13 rotatably mounted on the periphery of a rotary turret conveyer 12. Each bottle cup is provided with a drum which by the action of friction bands 21 and 22 driven for example by electric motors, on the surface of the drum causes the bottle and its contents to rotate. The friction bands 21 and 22 may be driven in opposite directions to produce an agitating action on the contents of the bottle. On entry into the inspection area between a fixed light source 38 and a photo-electric cell 40, the rotation of each cup and bottle is stopped by a brake (Fig. 3, not shown) acting on the respective drum, thus causing the contents to rotate relative to the bottle. When foreign particles are detected in the contents, the bottle is rejected by known means.

Patent GB-593100-A (GB)
Title: Improvements in or relating to projectiles of the self-propelled or rocket type
IPC: F41F3/04
Filed: 1945-05-31
Abstract: 593,100. Launching rockets. HYDRAN PRODUCTS, Ltd., and MOTLEY, L. May 31, 1945, No. 13666. [Classes 9 (i) and 92 (ii)] A projectile of the selfpropelled type is launched by the ignition of a rapidly burning launching charge whose products of combustion react with the launching apparatus to give the projectile a rapid initial acceleration after which it is sustained in flight by the ignition of a relatively slow burning charge, the projectile being fitted with a longitudinally slidable sealing device adapted to come between the products of combustion and a part of the launching apparatus to provide a seal for the products of combustion. In the construction shown in sectional plan in Fig. 2, rounds 3 are fed in succession to the rear end of a launching tube 1 from a magazine, and each round is launched from the tube by a rapidly burning charge 4 being subsequently retained in flight by a relatively slow-burning rocket charge 5. For firing the charge 4 a massive block 9 is mounted for longitudinal reciprocating movements in a tube 8 extending rearwardly from the breech chamber. The tube 8 has slots for guiding lugs 26 on the block, the lugs carrying forwardly extending rods surrounded by springs 12 which are compressed when the block is retracted. The block is held in the retracted position by a latch 11, and when the latch is released the block moves forwardly under the action of the springs 12, and a rod 10 carried by the block enters a tube 6 in the rocket and strikes a detonator cap 14 which ignites the charge 4. The detonator cap is fitted in a piston-like structure 13, and to the rear of this is a driving band 18 with which rod 10 makes a splined engagement. When charge 4 therefore is ignited the rocket moves forwardly, and the parts 13, 18 and 10 move rearwardly, the parts 13 and 18 being eventually stripped from rod 10 by the base 7 of the round. When the parts 13, 18 reach the rear end of the tube 6 they uncover a ring of openings 21 thus permitting hot gases from the combustion of charge 4 to make contact with and ignite the charge 5. The explosive charge 22 is contained in the nose of the round. The rod 10 in making a splined engagement with the driving band 18 prevents it from rotating, and as the inner surface of the tube 6 is rifled the round is, by this arrangement, rotated as it is propelled. As shown in Fig. 1a, the latch 11 is controlled by a solenoid 23 which, when energized, moves a lever 36 which rotates a lever 41 which is pivoted to a member 39. The pivotal movement of lever 41 takes place about a pin 42 which is held stationary by a spring-pressed strut 43, with the result that the upper end of lever 41 is moved to the left carrying member 39 with it and thereby actuating the latch 11. Just after the actuation of the latch the lever 36 rides past the lower end of lever 41, and when the solenoid is de-energized it again rides past it momentarily lifting the pin 42 from the strut 43 in so doing. Specification 588,920 is referred to.

Title: Compandor
IPC: H04B1/64
Filed: 1963-04-05
Abstract: 974,455. Compandors. STANDARD TELEPHONES & CABLES Ltd. April 5, 1963 [April 12, 1962], No. 13690/63. Heading H4R. In a pilot-controlled compandor circuit in which a constant amplitude pilot signal and the V.F. signal are added and applied to a compressor controlled by the amplitude of the V.F. signal, the resulting signal being transmitted and then applied to an expander which is controlled by the amplitude of the pilot signal, the pilot signal is used to transmit additional information, e.g. by frequency modulation of the pilot signal. Fig. 1 shows one embodiment of the invention in which an analogue signal source, e.g. a U.F. source in the frequency range 0-3.3 kc/s., is added in a mixer 7 to a pilot signal from a source 2 and applied to the compressor 8 which includes a vario-losser 9 controlled by the analogue signal source via amplifier 11. The resulting signal is applied to a modulator 13 for transmission over a cable or wireless link 16. At the receiver the signal passes through a variolosser 19 to a conventional self-synchronizing demodulator circuit 22, 23, 24, and an amplifier 25 to filters 26 and 27 which separate out the pilot signal from the analogue, or U.F., signal, the pilot signal being rectified to provide a control voltage for the vario-losser circuit 19 in the expander 18. In addition, the information impressed upon the pilot signal, in the form of an " on-off" code " on " being represented as a first frequency, i.e. 3.7 kc/s., and " off" by a second frequency, i.e. 3.9 kc/s., is extracted by passing the pilot signal through a limiter 31 and a discriminator 32. In a modification of the transmitter compressor the vario-losser is controlled in a retroacting circuit from the output of the variolosser, the V.F. signal being separated from the pilot signal by a 3.3 kc/s. low-pass filter in the control circuit, Fig. 3 (not shown). Alternatively the vario-losser may be inserted into the transmission channel after the channel modulator, Fig. 4 (not shown). The compression and expansion circuits may be provided for each channel of a multichannel transmission circuit, Fig. 5 (not shown).

A tractor-mounted reversible plough, of the type having duplicate plough-bodies 1, 2 or discs mounted on a frame 4 rotatable about a longitudinal axis, is provided with a disccoulter 52 which is automatically moved laterally by the reversal of the frame 4 so that it always precedes the leading operative body or disc. The reversing frame 4 is mounted on a shaft 5 carried in bearings 17 on a main frame 18. The main frame is adjustably supported on the tractor lift-links 67 by means described in Specification 665,666. The reversing frame is locked in position by a spring- loaded bolt 19 engaging holes 21, 22 on adjustable plates carried by the frame 4. Reversal is effected by a lever 38 (Fig. 1) which rotates a quadrant 30: this quadrant meshes with a bevel wheel 26 free on the shaft 5 but driving it through a lostmotion connection 27 to a collar 29. The bevel wheel incorporates a cam-track 31 over which runs a roller 32 on a lever 34 embracing the bolt 19. The lostmotion connection 27 permits the bolt 19 to be withdrawn before rotation of the shaft 5 commences. The front end of the shaft 5 carries a cam 59 to which is adjustably secured an arm 58 pivoted to a collar 56 on the stalk 54 of a disc-coulter assembly including a coulter 52 swivelly mounted on a yoke 53 on the lower end of the stalk, 54, the upper end being cranked and pivoted at 55<SP>1</SP> to a standard 36 on the main frame. Rotation of the shaft 5 causes the stalk 54 to swing laterally about its pivot 55<SP>1</SP>. In a modification (Fig. 11), the stalk 54 is not cranked at its upper end but is keyed to a crank 61 rotatable on a pin 64. The lower end of the stalk is cranked slightly to permit reversal of the stalk for longitudinal adjustment of the coulter (to the dotted position). The plates 23 carrying the bolt slots 21 (Fig. 9), are adjustable around the shafts 5 by a screw device 50.
