Title: Improvements in or relating to cigarette packing machines
IPC: B65B19/10
Filed: 1928-02-03
Abstract: 284,724. Popov, V. D. Feb. 4, 1927, [Convention date]. Packeting cigarettes in receptacles.-The invention relates to apparatus for counting cigarettes in cigarette packing machines in which a filling drum 3 passes cigarettes into a channel 17 from which they are forwarded by a grooved counting drum 26 into a receiver 33, and consists in causing each cigarette, before it enters the receiver, to contact with a control lever adapted to rock if one of the grooves of the counting drum contains either no cigarette or a poorly filled one, and to operate a mechanical relay which closes an electric circuit and thereby stops the machine. The actuation of the filling and counting drums is dependent on the presence in the receiver of a paper case for the cigarettes. The grooved drum 3 by which the cigarettes are fed into the channel 17 is rotated intermittently by a ratchet 16 and pawl 13 on a. plate 12 oscillated by a crank arm 10. Normally, a finger 43 on a lever 39 projects into the ratchet teeth and holds the pawl 13 away from them, the other end of the lever projecting into the path of slotted sleeves 47 on a rotating drum 45 adjacent the receiver 33. The sleeves receive the paper cases in which the cigarettes are to be packed. When a paper case is disposed in a sleeve 47, the case engages the end of the lever 39 turning it to draw the finger 43 clear of the ratchet 16 and permit the pawl 13 to function; if no case is present, the end of the lever 39 projects idly into the slot in the sleeve. The counting drum 26 is geared to the filling drum 3. As it rotates, one arm of a threearmed, spring-pressed lever 52 engages each cigarette and is oscillated thereby. An insufficiently filled cigarette or the absence of a. cigarette increases the amplitude of the oscillation causing a two-armed lever 57, which rests upon the upper arm of the lever 52, to drop. This motion disengages the second arm of the lever 57 from the end of one arm of a second two-armed lever 58, the other arm of which is weighted. This weighted arm then drops, closing contacts 60, 61 and thereby making the electric circuit 62, 63 which stop the machine. The device may be applied to a machine for filling packets with two rows of cigarettes.

Abstract: 1,191,395. Jib cranes. JONES CRANES Ltd. 23 Jan., 1969, No. 3663/68. Heading B8B. [Also in Division F1] A crane jib assembly includes a jib with four telescopic sections 54 to 57 of rectangular crosssection. The end section 54 is pivotally secured through a pair of bushes 58 to brackets 52 on a crane body 51 mounted for slueing on a lorry (50), Fig. 1 (not shown). A telescopic ram with sections 1 to 4 is also pivoted to a bracket 52 on the crane body 51 and connected by a bush 38 and boss 34 to the upper end of the jib section 57. Pairs of tie-ropes 61 are connected between flange 7 of ram section 2 and the end of the jib section 55 adjacent the crane body 51, tie-ropes 62 being similarly connected between flange 6 of the ram section 3 and the end of the jib section 56. Application of hydraulic pressure (by means not shown) to the ram initially extends the ram section 2, owing to its larger larger effective area and with it the jib section 55 with the jib sections 56, 57 inside until stop 59 on the jib section 54 is contacted by abutment flange 60 on the jib section 55. The jib sections 56, 57 are similarly extended, in order, the stops 59 and abutments 60 limiting the jib extension to a predetermined maximum. The tie ropes 61, 62, owing to the continuing pressure in the ram, pre-tension the jib sections, such pretensioning being increased by the application of a longitudinal load on the jib since such a load increases the pressure in the ram, which may have an hydraulic accumulator. The jib is luffed by a derricking rope and has an adjustable buffer (67) to act as a back stop. A fixed jib extension (68) may be secured to the upper end of the jib section 57.

Title: Continuous casting of channel-shaped strip
IPC: B22D11/06
Filed: 1972-01-26
Abstract: 1384257 Continuous casting JONES & LAUGHLIN STEEL CORP 26 Jan 1972 [26 Feb 1971 9 Nov 1971] 3751/72 Heading B3F  Channel-shaped strip is cast by pouring metal, e.g. steel from a tundish nozzle 49, Fig. 1, on to an inner surface 23, Fig. 2, of a ring 10 supported for rotation (by flanges 11 on rolls 12, 13) and cooled by coolant 46 applied to the outside to solidify the metal, there being surfaces inclined to the surface 23 to form the side walls of the channel strip, these surfaces being either surfaces 24 integral with surface 23 or surfaces (65) provided by separate, stationary side members (64), Fig. 4 (not shown), adjacent the sides of the ring at the bottom where the pool of metal is maintained. A scraper 50 lifts the cast strip from the ring 10 (which is driven by the roll 13 whose shaft is driven by a motor 18 and belt 20) to raise the strip from a pool of metal in the bottom of the ring. There may be used a rotatable roll 25 supported on a pivoted arm 29 and which mates with the inner surface of the ring 10 or that surface and the stationary surfaces (65) and is supplied internally with coolant. Its shaft 28, mounted on the arm 29, is driven by way of changeable gears 30-34 from the shaft 21 of roll 13. A weight 37 suspended on a rod 36 from the arm 29 may control the thickness of the cast strip or the rod 36 may be limited in movement or locked in position, by nuts 52, 53, for such control. By selection of the length of arm 29, the roll 25 may be the lowest level 25<SP>1</SP> or nearer the scraper 50 as shown so that the strip may or may not be chilled from both sides as it starts to solidify. In the former case, a solidified layer adjacent the roll becomes welded to a layer against the ring in the nip between them.  The bevelled ends 27 of the roll 25 and/or ring flanges corresponding to the surfaces 24 may be fluted to produce a wavy edge on each side wall of the cast channel strip to provide extra metal to facilitate flattening.

Abstract: 440,069. Spray carburetters. SOC. DU CARBURATEUR STRATOS, 43, Avenue de l'OpÚra, Paris. Feb. 5, 1935, No. 3776. Convention date, Feb. 5, 1934. [Class 7 (iii)] In a carburetter in which a suction operated piston 4 controls the inlet of air to a mixing chamber 1 and the vacuum therein is maintained substantially constant, a tube 29 directed towards the incoming air in the air inlet 2 directs an air blast into the top of the float chamber 12 to increase the pressure therein, the power of the blast diminishing as the density of the air decreases at higher altitudes. As shown, an emulsion is formed in a chamber 18 communicating with the mixing chamber 1 through a port 19 and the vacuum prevailing in this chamber is modified also according to altitude by providing a passage 21 which leads therefrom and enters the air inlet in a direction away from the air current. As shown, the passage 21 is fixed in area but the stem passing through it may have a varying cross-section to modify the passage with the displacement of the piston 4. In a modification, the passage 21 opens into the air inlet facing the air stream and is masked by a cone having its apex directed towards the inlet, the distance of the cone from the opening being adjustable.

Abstract: 372,814. Washing granular materials. KINGS PATENT AGENCY, Ltd., 146A, Queen Victoria Street, London.-(Findlay, H. C. ; Waitangi, Kiambu, Kenya.) Feb. 7, 1931, No. 3950. [Class 82 (ii).] In washing coffee, cocoa beans, or other oil-bearing fruits the material is introduced with water into a vessel divided into several compartments, o r into a series of vessels, the compartments or vessels being arranged so that the fruit travels in a sinuous path, and upward currents of water of increasing intensities are caused to act on the fruit-bearing stream at various points in its course through the vessel or vessels. A vessel 1 is divided into compartments 2, 3, 4, connected by vertical pipes 7, 11 leading from the bottom of one compartment to near the top of the next. The fruit and water are introduced into the compartment 2 through a pipe 5, the lightest particles overflowing at 6. The remainder passes with the stream of water up the pipe 7 into the compartment 3 where the lighter particles overflow at a into a discharge trough 13, the remainder passing down the sloping bottom 8 through an opening 20 into a flume 9 forming part of the compartment. Water under pressure is supplied by a valved pipe 10 to the bottom of the flume 9 and rises therein carrying the constituents of a certain density over an adjustable weir 14<1> into a discharge trough 14. The heavier particles are carried by the stream up the pipe 11 into the compartment 4 which is similar to the compartment 3 and contains a flume 16 connected to a pipe 17 carrying water under pressure, the pressure being greater than that in the pipe 10. Another grade of fruit passes up the flume and over an adjustable overflow d while the heaviest fruit is carried on and up a pipe 18 from which it is discharged.

Abstract: 994,686. Rotary conveyers. SIEMENS & HALSKE A.G. Jan. 31, 1964 [Feb. 1, 1963], No. 4112/64. Heading B8A. An apparatus for conveying flat articles 12, e.g. cards, envelopes, between loading and unloading points 11, 14 comprises a plurality of separate containers 1 each adapted to accommodate a batch of cards 12 and each being driven independently of the others between and halted at, the loading and unloading points which are spaced along a circular transport path for the containers. Each container 1 is pivotally mounted at 4 to a pair of radial arms 2 which are interconnected by a tube 10 and rotatably mounted on a spindle 3. The attitude of each container 1 is controlled by an arm extending therefrom and incorporating a follower 5 engaging a cam groove 6. A common drive belt from a motor 7, Fig. 2 (not shown) runs over friction drivers 8 each of which is coupled via a spindle and gear 36 to a drive wheel 9 associated with each container 1. The cards 12 are successively delivered from a conveyer 13 into a container 1 where with the aid of a guide 21, Fig. 4 (not shown) they are deflected and fall forming a vertical stack. As the latter reaches a predetermined height, a light beam 27, Fig. 5 (not shown) which is reflected off the back of the container 1, is interrupted and provided a further light beam 26, Fig. 4 (not shown) is not interrupted by a card being delivered from the conveyer 13, the latter is caused to stop and a magnet 30, Fig. 6, is energized causing a pawl 31 to be withdrawn from a stop 32 on a toothed sector 29 so that the container is driven to its unloading point. A sector 29 is associated with and moves with each container 1. A fixed guide plate 15 retains the cards 12 in the containers 1 as they move through their lower arcuate path. The motion of the container is stopped either by abutment with a container already unloading or by the top tooth of the sector 29 engaging a pawl 34. The cards 12 are individually unloaded on to a conveyer 14 by a suction device 16 while the height of the remaining stack is sensed by a feeler 18. The latter actuates a coil 35 when the stack level has fallen by a predetermined amount, and causes the pawl 34 to be withdrawn from the section 29 which allows the container 1 to rise until the lever 18 again causes the pawl 34 to be released. A step-by-step motion is thus generated during unloading, until fully unloaded when the sector is relevant and the container passes along the upper arcuate path to the loading point. Apertures 19, 20 are necessary in the container walls to allow passage of the suction device 16 and the guide 21. The various directions in which the cards 12 may be loaded into and unloaded from the containers 1 can be seen in Figs. 7a to 7d (not shown).

Filed: 1975-01-30
Abstract: 1484793 Gyroscopic stable reference apparatus SPERRY RAND CORP 30 Jan 1975 [6 Feb 1974] 4167/75 Heading G1C A gyroscopic stable reference platform 10 for mounting on a vehicle and providing attitude information about three mutually perpendicular reference axes provides a control arrangement for momentarily disabling an outer roll gimbal servo to prevent unstable operation of the platform. The platform 10 comprises a first gimbal 13 pivotally mounted for rotation about a roll axis 14, a second gimbal 20 pivotally mounted on the first for rotation about a pitch axis 23, a vertical gyroscope 24 having an inner gimbal 25 mounted for rotation about an inner roll axis 28 on the second gimbal 20, and a directional gyroscope 35 which is also pivotally mounted on the second gimball 20 for providing an azimuth reference. The spin axis 31 of the vertical gyroscope is maintained in alignment with the gravity vertical by control means which, as described, comprise pitch and roll accelerometers 50, 51 coupled to pitch and roll erection control amplifiers 52, 54 which supply signals to torque motors 53, 55 respectively. The pitch axis 23 is maintained perpendicular to the spin axis 31 of the vertical gyroscope 24 by means of an inner gimbal pick-off 60 which senses movement of the inner gimbal 25 about the inner roll axis 28, a resulting signal being applied to a servomotor 62 via circuitry including a switch 105. Pitch and roll pick-offs 64, 65 and an azimuth output resolver 66 provide the attitude information required. The switch 105 may be opened to disable the servomotor 62, by means of a control 106 which may be operative upon receiving an output from an AND circuit 104 which is produced only when circuit 104 receives simultaneously three inputs, one each from a pitch level detector, a pitch rate detector 102 and an inner roll angle detector. Descriptions of possible detectors 101, 102 and 103 are given. Further, excessive acceleration experienced by either of accelerometers 50, 51 causes a signal which disengages the respective erection amplifier 52, 54 to avoid axis 31 following a false vertical.
