Title: Improvements in or relating to air pressure actuators for gear change mechanisms
Inventor: PAGE WILBUR MILLS
IPC: F16H63/30
Filed: 1966-04-04
Abstract: 1,142,506. Gear-shift actuator. CLAYTON DEWANDRE CO. Ltd. 30 June, 1967 [4 April, 1966], No. 14831/66. Heading F2D. [Also in Division F1]  Three position piston and cylinder type pneumatic gear shift actuator, having a central " neutral " position and two end '' gear engaged " positions, exerts a low force over the first part of the piston travel from " neutral " to a " gear engaged" position to avoid overloading a synchronizing device, and a larger force over the remaining portion of said travel. A stepped piston 5 connected to a gear shift member has reduced portions 5a, 5b slidable into and out of bores of respective annular pistons 7, 8 which are slidable in cylinder 1, 2. The full diameter portion of piston 5 is slidable in a larger bore of piston 8, as is a reduced portion 7a of piston 7. If air is supplied to both ends of the cylinder, pistons 7, 8 are urged against a stop 9 to hold piston 5 in " neutral." If air is supplied only to end 2 of the cylinder, it acts only on reduced end 5x of piston 5 until reduced portion 5a is clear of piston 7. Then pressure acts on the full piston 5. For movement to the other " gear engaged " position, air is supplied only to the right-hand end of the cylinder. Ports 10 with check valves 11 allow air to escape from the spaces between pistons 5 and 7 or 8 during return from a " gear-engaged " position to the neutral position.

Title: Improvements in conveying mechanism
Inventor: TOONE REGINALD JAMES
IPC: B65B35/24
Filed: 1965-04-08
Abstract: 1,068,137. Endless conveyers. ROSE BROTHERS (GAINSBOROUGH) Ltd. March 30, 1966 [April 8, 1965], No. 14881/65. Heading B8A. Blocks 13 of margarine being transported on the upper run of an endless belt 11 of a wrapping machine are caught up by flights 23 depending from faster moving endless chains 15. Irregularly placed blocks 13 on the belt 11 are thus brought into precise position for transfer by the flights 23 into pockets formed by members (38) (Figs. 4 and 6, not shown) on a conveyer (37) of a cartoning machine. The flights 23 are initially held up clear of the blocks 13 as they pass from the upper to the lower run of the chains 15, by the action of a guide (42) (Figs. 1 and 3, not shown). Each flight 23 is freely pivoted on a shaft 22 carried by brackets 20 respectively mounted on the chains 15. Also pivoted on the shaft 22 is an arm 27 carrying a roller 28 engaging a cam track 29 which extends around the whole run of the chains 15. Rigid with the arm 27 is a latch plate 32 which carries a latch 34 adapted to engage a pin 36 carried by an extension arm 24 of the flight 23. Thus when the guide 42 permits the flight 23 to fall (from the position of Fig. 5) into a depending block-engaging position (Fig. 6, not shown), the pin 36 is engaged behind a nose 43 of the latch 34. This prevents rearward movement of the flight 23. The latter is maintained vertical during the transfer of the block (Fig. 6, not shown), even though the chains are passing up round their return sprockets, by the action of the roller 28 and cam track 29. There is a second conveyer belt 12 side-by-side with the belt 11 and alternate flights 23 are aligned respectively with the two belts 11 and 12.

Patent GB-108402-A (GB)
Title: An Improved Threading Mechanism for Automatic Lathes.
IPC: B23B9/02
Filed: 1916-10-19
Abstract: 108,402. Marks, E. C. R., (Fitchburg Machine Works). Oct. 19, 1916. Screwing.-A threading spindle for use in automatics in which the work rotates continuously in one direction has a special control mechanism mounted on a support removable as a unit from the machine and arranged to be fixed on an auxiliary frame behind the tool head in either or both of the spindle positions. An auxiliary frame 18, Fig. 1, has two guide-ways to receive supports 21, Fig. 5, for the control mechanism secured by screws. Dog bars 36, 37, one for each of the two positions, slide in the tool head 15 at 38 and are connected by a cross-head 39 carrying a rod 40 guided at 41 and actuated at 42, 46 from the cam shaft. The dogs act during the forward motion of the bar and are pivoted and spring controlled for an idle return. The screwing-spindle 33 is in two parts connected by a pin and slot 232 and spring 234 to facilitate starting the thread. A rack sleeve 22 loose on the spindle is geared to a sector 27 having adjustably connected to it a roller arm 30. During the forward motion of the dog bars, three dogs come into action successively. The first dog engages the roller-arm and feeds forward the spindle, passing above the roller at the; time the die engages the work, thus preventing backward motion of the spindle and securing the starting of the thread. A sleeve 50 is so connected to the spindle by a tumbler 51, Fig. 9, that a limited angular movement is permitted. In the initial position shown, the gear 53 drives the spindle 23 at a lower speed than the work spindle through a pawl 57 yieldingly held in position by a light spring. As soon as threading commences, the spindle 23 attempts to over-run the sleeve and the tumbler 51 assumes the position shown in Fig. 8, and positively maintains the pawl in position, so that the ratchet retards the spindle. On completion of the threading, the second dog engages a projection 74a, Fig. 5, on a lever pivoted at 75 and having a pin and slot connexion at 73 with a second lever so giving a quick traverse through a stud 67, Fig. 6, to a sleeve 66 connected at 62<a> to a stepped sleeve 62 and raising a pawl 61 on the sleeve 50 into engagement with ratchet teeth in a gear 52 driven to overrun the work spindle. The spindle 23 then lags behind the sleeve returning the tumbler to the position shown in Fig. 9 and allowing the sleeve 50 to overrun the gear 53. When a more definite thread-determining device is required, the collar 91 is set to shift the sleeve 66 by contact with the pins 90. When the die has run off the work, the third dog engages a shoulder 27<a>, Fig. 5, on the sector and returns the spindle to its initial position. Specification 9570/07 is referred to.

Patent GB-835523-A (GB)
Title: Cyclic siloxanes
IPC: C08G77/24
Filed: 1958-05-09
Abstract: The invention comprises cyclic siloxanes of the formula [(CF3CH2CH2)2SiO]n, where n is 3 or 4, which are useful as intermediates for higher siloxanes and for copolymers of bis (trifluoropropyl) siloxane with other siloxanes such as trifluoropropylmethyl- and diphenyl siloxane.  The compounds are prepared by the alkaline cracking of bis (trifluoropropyl) siloxanes, e.g. at temperature of 200-250 DEG  C. These siloxanes are best prepared by hydrolysing bis (trifluoropropyl) diethoxy silane, which is itself prepared by reacting trifluoropropyl chlorodiethoxysilane with a 1,1,1-trifluoropropyl magnesium halide.  Trifluoropropyl chlorodiethoxy silane is prepared by reacting 1.1,1-trifluoropropyl triethoxysilane and 1.1,1-trifluoropropyl trichlorosilane, preferably at about 130 DEG  C.  Specification 805,028 is referred to.

Title: Improvements in or relating to direct current circuit breakers
IPC: H01H71/24
Filed: 1922-05-30
Abstract: 195,340. Forges et Ateliers de Constructions Electriques de Jeumont. March 21, 1922, [Convention date]. A u t o m a t i c circuitbreakers.-A direct-current instantaneously-acting automatic circuit-breaker is arranged to be released by an electromagnet energized by two coils in two parallel blanches of the main circuit, one of said coils having a relatively large number of turns being connected in a branch of high non-inductive resistance, and the other coil, which has a relatively small number of turns in the second branch of high inductance so arranged that in the case of a sudden overload release will be effected at a lower current value than would ba the case in the event of a more slowly increasing overload. The switch arm A is released by an electromagnet having two windings in parallel branches of the main circuit, one coil a with a relatively large number of turns being of high non-inductive resistance which may be supplied by a series resistance r and the other coil b in series with an inductance c. On a sudden increase in load, due for instance to a shortcircuit, the greater part of the first influx of current passes through the coil a but in the case of a more slowly acting overload the major portion of the current passes through the coil b the two coils acting in conjunction. The coils a, b and their respective parallel circuits may ba arranged for release to be effected at a lower current value with a suddenly acting overload than would be the case in a more slowly acting normal overload. This arrangement also prevents accidental release in the case of sudden collapse in the load in which case the non-inductive branch a, r acts as a discharge path for the inductance c thus producing opposing currents in the coils a, b. An auxiliary choking coil d may be connected in the main circuit to facilitate this action. As applied to the circuit breaker shown in Fig. 2 the coils a, b are wound on a core c adapted to attract an armature b carried by the contact arm A pivoted at o. The arm A carries a second armature G adapted to be attracted by the closing electromagnet H when the control switch M is closed. The attraction of the axmature G is opposed by a spring I which may be adjusted to correspond with various valves of release by the electromagnet C. The relatively fixed contact is in the form of a horn D movable between stops K, L and above the arm A is a second pivoted sparking horn E. A blow-out coil J in series with the main current is arranged adjacent to the sparking horns E, F.

Patent GB-694007-A (GB)
Title: Improvements in seed pellets and in the manufacture thereof
IPC: A01C1/06
Filed: 1951-06-27
Abstract: Seed pellets are produced by applying to the seeds a water-permeable binder e.g. vegetable glues or animal glues adapted to be swollen by water and particles of cork or similar cellulosic or ligneous materials of vegetable origin.  A dense ingredient e.g. sand may be incorporated in the binder.  The coating may comprise several sections of increasing diameters, in particular an inner section where the sand may be incorporated, and an outer section which contains cork particles but no sand particles.  Additional ingredients such as fertilizers, growth stimulants, insecticides, anticryptogamics and the like may also be incorporated.  In an Example 3 kgs. of beetroot seeds divided into segments are placed in a spherical container which is rotated at a rate of about 25 revs. per minute whilst a gluey liquid consisting of 1 litre of water to which have been added 20 grams of the gluten glue sold under the name "N.L.T. glue" is sprinkled on until when about 300 cc. of liquid have been added there are added 250 grams of "Fontainebleau" sand.  The resulting seed pellets are removed from the container, sifted through a sieve with circular meshes of 3.75 mm. the pellets passing through being returned to the apparatus where the binder and sand are added as before until all the pellets are retained on the sieve.  All the pellets are then placed in a large container into which 300 cc. of the above glue solution are sprayed and 40 grams of cork meal are sprinkled alternately, these operations being repeated until the pellets formed are retained by a 5 mm. mesh screen, the pellets being then dried e.g. in a hot air rotary drier the temperature not being allowed to exceed 80 DEG C.
