Abstract: 1431968 Endless conveyers; discharging from shoots STORK AMSTERDAM BV 15 Oct 1973 [25 Oct 1972] 48509/73 Headings B8A and B8S Apparatus for feeding articles, e.g. plastics bottles 6, from a hopper 1 to a filling machine 2, by means of which the bottles are aligned and oriented prior to entering the machine 2, comprises a feed out means 3 with a regulatable metering vibrator 4 at the base of the hopper 1 from which the bottles are fed to two parallel transit paths 5 (only one shown) each path 5 being provided with a shaker mechanism 7 thus producing two rows of horizontally aligned bottles, the bottles then passing to an orientating device 12 at which those bottles not already having their bottom ends forward are turned, so that all the bottles leave the device 12 in two rows with their bottom ends turned to the front and pass into a respective conveying line 16 having means 17 for feeding compressed air thereinto such that the bottles are fed through the lines 16 into a downwardly slanting buffer portion 24 of each line 16 for holding a buffer stock of bottles, the bottles passing from the buffer portions 24 to a common feed worm 18 by which the bottles are fed to the filling machine 2. Each orientating device 12 comprises a pair of endless ropes 13 adjoining each transit path 5, and below each pair 13 is a pair of endless ropes (14) and one endless rope (15), Fig. 4 (not shown), the ropes (14) moving in the direction of conveyance while the ropes (15) move in the opposite direction, and those bottles which from the start are in the correct position come into contact only with the ropes (14) while bottles which have assumed the wrong position (i.e. necks forward) contact the ropes (15) and are turned over before being carried on by the ropes (14). For each conveying line 16 there is a rotary feed member for feeding bottles from the bottom of the line 16 to the worm 18, each such feed member comprising an upright partcylindrical rotatable wall part 20 with a helically-extending upper surface 21 rotating in a cylindrical casing, Fig. 6, and when the helical surface 21 lies under the exit from the associated buffer portion 24 a bottle is allowed to drop on to this surface 21 and due to the further rotation of the wall part 20 the bottle sinks to the level of the worm 18 and is pushed by the leading edge 25 of the wall part 20 into the helix of the worm 18. A sensing member 28 operates a stop member 27 to make the transit paths 5 inoperative when the quantity of bottles in the buffer stock is too large, and a sensing member 29 near the upper end of each buffer portion 24 also renders the associated transit path 5 inoperative when the quantity of bottles in the buffer portion is too great, while a sensing member 30 above the exit from each conveying line 16 operates a stop pin 23 to prevent exit of bottles from the lines 16 when the quantity of bottles in the buffer portions 24 has decreased too far.

Abstract: 1490454 Translucent polypropylene film MITSUBISHI RAYON CO Ltd 26 Nov 1975 [29 Nov 1974 12 Sept 1975 16 Sept 1975 6 Oct 1975] 48585/75 Heading B5B [Also in Division H1] The film contains no beta-type crystallization agent and has on one side at least a surface layer composed of a two or three-dimensional network structure in which the network elements constituting the network structure are present to the extent of at least 1000 per square cm. of film surface. The film is formed by biaxially stretching an unstretched polypropylene sheet having on one side a surface layer having a K value (i.e. the amount of #-type crystals present at a portion from the wall to a thickness of 10% in the thick wall direction) of at least 0À1 under conditions that the stretching temperature at the stretch initiation point is in the range 145-176 C. and the stretch ratio in one direction is less than 8 : 1 and the preheating time from the preheating initiation point to the stretch initiation point is less than 150 seconds. The unstretched film 3, Fig. 1, is formed by melt extrusion through the annular slit 2 of a ring die 1, compressed air is fed through pipe 7 to expand the tube to enable it to slide in contact over the cylindrical member 4 maintained at 30-110 C. while the outer surface of 3 is cooled with a liquid to a temperature below that of 4 and wound up after passing through nip rollers 10. The coolant 13, in bath 11 is maintained at a constant level by an overflow pipe 12 and the coolant 13 is caused to circulate in the direction of the arrows by the water ring 9. The cylinder 4 is cooled by the passage of coolant through pipe 5 and out through pipe 6 while compressed air is passed into the lower part of the tube through pipe 8. Alternatively a tubular melt 16, Fig. 2, is maintained in sliding contact and at a temperature of the inner surface of 130-200 C. with the outer periphery of one or more disc like members 17 while the outer surface of 16 is cooled by coolant 19 preferably water. The discs 17 may be of metal, ceramics, glass, carbon or PTFE. A further process using an apparatus similar to Fig. 1 comprises passing a tubular film, extruded from an orifice at 230 C. or less and at a velocity of 1À5 cm./sec. or more over a cylindrical member maintained at a temperature of less than 45 C. while the outer surface of the film is maintained at a temperature above 45 C. and preferably below 130 C. In an alternative arrangement, the cylindrical member surrounds the outer surface of the film and the liquid coolant is contained in the blown film. A flat sheet is formed as in Figs. 5 and 6 by contacting one surface of the film with a roll kept at 30-130 C. while the other side is kept below this temperature. The rolls may be of the same material as discs 17 above. Rolls 43 and 45 are hot silicon rubber rolls and 42 and 44 cooled chromium-plated rolls; roll 48 is made from PTFE and the medium 49 is water.

Title: Steering apparatus for marine jet propulsion units
IPC: B63H11/11
Filed: 1974-11-12
Abstract: 1491247 Water jet propulsion BRUNSWICK CORP 12 Nov 1974 [30 Nov 1973] 48907/74 Heading B7V A water jet propulsion unit includes a deflector nozzle 22 for steerage and trim control and an auxiliary rudder 19 whose respective steering axes 12, 55 are offset and which are interconnected by a pair of depending arms 56, 57 of the nozzle 22 slidably engaging an upper portion of the rudder 19 so that the effect of the rudder 19 alters with the trim position of the nozzle 22. Consequently the rudder 19 improves steerage at low speeds with the nozzle 22 pointing downwards since the rudder axis 55 moves off of the steering axis 12 causing an amplified rudder movement for any angular movement of the nozzle 22. Conversely at high speed with nozzle 22 trimmed up, i.e. nearer to the horizontal, the rudder axis 55 moves closer to the steering axis 12 with a resultant reduction in angular movement of the rudder 19 for a given angular displacement of nozzle 22. The point of contact of the arms 56, 57 on the rudder moves arcuately with the nozzle 22 being moved from trim up to trim down or vice-versa along a path 59 (Fig. 5), e.g. between contact points 62 and 61 respectively or vice-versa. The nozzle 22 is mounted in a gimbal ring 14 which pivots about trim axis 15 on pins 30, 31 and which is secured to the nozzle 22 by pins 28, 29 defining the steering axis 12. A steering lever 33 is connected by a universal linkage 34 to the steering mechanism of the watercraft and an actuator 16 is connected by a link 17 to the ring 14 for trim control. A reversing gate 27 is provided to deflect the water jet through a reverse nozzle 44.

Abstract: 1284414 Curable polymercapto resin compositions DIAMOND SHAMROCK CORP 6 Oct 1969 [7 Oct 1968] 49013/69 Headings C3B and C3R A liquid resinous composition which cures on exposure to oxygen comprises a liquid resin having at least two SH groups and a molecular weight of 800-10,000 prepared by the introduction of SH groups into a polymeric substance other than a polymer comprising repeating units containing -S-S- linkages, and an additive which comprises a metallic soap drier. The additive is either (1) a soap in which the metal is cobalt and/or iron, (2) a soap in which the metal ion is one or more of Co, Cu, K, Na, Fe and Mn, in combination with calcium peroxide, or (3) a mixture of a soap in which the metal is Fe, Co and/or Mn with a soap in which the metal is Pb and/or Zn. The acid radicals of the soaps are derived from C 6 -C 22  monocarboxylic acids. The preferred resins are those derived from an alkylene oxide and a polyhydric alcohol, the polyether condensate being reacted with a haloepoxide to form a halogenated polyhydric polyether and then with sodium sulphhydrate to convert the terminal halogen to SH groups. The resins may also be derived from polyepoxides by reacting with H 2 S or first with an epihalohydrin and then with a sulphhydrate. Many examples of polyepoxides are listed. These polymercaptans may be mixed with polymercaptans prepared by reacting H 2 S with polythiiranes or with polymercaptans prepared from epoxidized polymers and copolymers of isoprene or butadiene as well as mercaptoethyl esters of polyacrylic acid and mercaptobutyl esters of methacrylic acid-styrene copolymers. The soaps may be used in solution to facilitate dispersion in the polymer. The compositions may contain additives, e.g. TiO 2 , CaCO 3 , gammamercaptopropyl trimethoxy silane (adhesion promoter), hydrogenated castor oil (thixotropic agent), crystalline aluminosilicates (moisture scavenger), dioctyl phthalate (plasticizer), barium oxide.

Title: Device for maintaining the frequency of a voltage controlled oscillator
IPC: H03L7/081
Filed: 1973-10-26
Abstract: 1431704 Automatic frequency control COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT - ALCATEL 26 Oct 1973 [6 Nov 1972] 49982/73 Heading H3A A circuit for locking the output f 2  of a voltage controlled oscillator P to a reference signal f 1  comprises: a comparator L which receives the two signals 1, 2 and produces a square-wave output Q 0  having a mark/space ratio dependent on the frequency difference; and an integrator G having one input E 2  connected via an impedance network Z 2  to the output Q 0 , and a second input E 1  connected to a signal source via variable resistance R 3  which can be adjusted to vary the phase angle between the signal f 1 , f 2  when they are locked. The signal connected to the input E 1  may be a complementary signal Q 0  derived from the comparator L, or may be a fixed reference. When it is desired to start synchronization operation transistor T 3  is momentarily turned on by a pulse from monostable M 0  to discharge integrator capacitor C 0  and set oscillator P to its maximum frequency, which is higher than the reference frequency. The two input signals 1, 2 are divided at 3, 5 and differentiated at 4, 6 to provide pulse trains which set and reset bi-stable Y 1  as long as signal 2 is at a higher frequency than signal 1, Y 1  being set by signal 1 and reset by signal 2. The falling pulse edge of output Q 1  applied to input H of bi-stable Y 2  is therefore coincident with pulses of signal 2 applied to Z of bi-stable Y 2  and produce no change in output Q 2 . As soon as the frequency of signal 2 falls below that of signal 1, two pulses of signal 1 occur within the interval of two signal 2 pulses and the second of them set bi-stable Y 2  to produce a "1" at Q 2 , which is then reset to "0" by the next pulse of signal 2. The Q 2  pulse thus produced sets Y 3  to give a "1" at Q 3  which: (a) enables gate 7; (b) applies a "1" to input K of bistable Y 0 ; (c) turns off transistors T 1 , T 2  to increase the time constant of integrator G. The output from bi-stable Y 0  now adjusts to a pulse train having a constant mark/space ratio which is determined by the setting of resistor R 3 . This determines the locked phase difference between the two signals. If signal 1 fails the "1" at input K of Y 0  ensures that Y 0  is switched at half rate by signal 2 to provide a memory until signal 1 restores. If synchronization is lost, coincidence of pulses in signals 1 and 2 produce an output from gate 7 which triggers monostable M 0  to start another search.

At the end of the control pulse, transistor 6 conducts and capacitor 13 discharges to speed the build-up of current in winding 4 and the flushing of charge carriers from the base of transistor 5. Initially, current is supplied to winding 4 through parallel resistors 17, 18, but when the core of transformer 1 saturates the voltage across winding 4 falls to a low value and control circuit 16 switches off transistor 19 so that winding 4 is supplied through the higher resistance 17 only. The power supplied to load 10 may be varied by varying the width of pulse 12.

In an intermittent drive for a printing machine web feed roll, comprising a continuously rotating input gear 1 coaxial with an output wheel 5 having peripheral arcuate recesses 35, an axially projecting pin 6 rotatably mounted in the gear 1 is rotated into a first position in which its semi-cylindrical head drivingly engages a recess 35 of wheel 5, and into a second position in which the head clears the wheel 5, by adjustably positioned stationary cams 12, 13 respectively, which act through a sector gear 8, pivoted at 30 to the gear 1, and a pinion 7 secured to the pin 8. Roller followers 10, 11 on the sector 8 engage the cams 12, 13 respectively. Overcentre action of a tension spring 16 and an arm 14 pivoted at 30 on a lug 15 of the sector 8 locates the latter in its alternative positions. To hold the wheel 5 stationary when not engaged by the pin 6, a cam 17 secured to the gear 1 acts on a follower 18 of a bell-crank 19, 31 having a fixed pivot 20, to engage a roller 21 with a recess 35 of the wheel 5 or of a similar wheel 22 secured thereto (Fig. 2, not shown). A spring urged roller 23 acts on the end 34 of the bell-crank to locate roller 21 in either of its engaged or disengaged positions. Re-engagement of pin 6 with wheel 5 unseats roller 21 to move it to the disengaged position.
