Title: Cigarette í¡í¡
IPC: A24C5/18
Filed: 1960-03-10
Abstract: 946,455. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. March 10, 1960 [March 20, 1959], No. 8517/60. Heading A2C. [Also in Division G1] A continuous tobacco rod 8 is cut by a knife 68 off the lower end of a hollow tobacco cylinder 14 formed by feeding tobacco particles to the space between two rotating cylinders 10, 12. The outer cylinder 12 is supported and driven by three sets of rollers 30 and drives the cylinder 10 through a flexible link 54, Fig. 3. The cylinder 10 is mounted eccentrically on a control shaft 46, rotation of which superimposes a slight orbital motion on to the rotary motion of cylinder 10 so that the width of the gap between cylinders 10, 12, is continually increasing and decreasing to assist compacting of the tobacco. The bottom of cylinder 10 and of a plate 66 attached to cylinder 12 form leger plates for the knife 68, the lower end of the tobacco cylinder being supported by a plate 16 carried by a member 18 rotated by gears 28, 44, from the shaft 30. A flexible belt 70 closes the gap between plate 16 and lower end of plate 66 except in the region of knife 68 where a stationary guide 86 supports the side of the cut-off strip 8 and a stripper member 88 detaches the strip from the cylinder and guides it on to a conveyer 90 leading to the cigarette paper conveying band 94 of a rod forming mechanism. The guide member 88 also has a ramp portion 92 guiding the stepped end of the tobacco cylinder back to the level of plate 16 after removal of the strip. The loose tobacco is fed on to a rotating plate 62 which flings the particles into the gap 14, the rate of feed being such as to keep the height of the tobacco cylinder constant, The rate of feed may be controlled by a photo-electric device operated by the level of the tobacco cylinder showing through a window 108 in cylinder 12. The density of the tobacco rod may be adjusted by varying the speed of conveyer 90 relative to that of conveyer 94 or by varying the depth of the strip 8 by rotation through a chain 104 of a screwed nut 106 which varies the position of the member 18 carrying the plate 16. The adjusting means may be controlled automatically by a device which measures the density of the tobacco rod and produces an electric signal controlling a servomotor actuating the adjusting devices. Specification 707,239 is referred to.

An inductive winding has a portion of a conductor arranged in two or more pairs of disc coils A2, B2 . . . A5, B5 (Fig. 6), spaced apart along a common axis, a first set of turns of the conductor in each coil of a pair or pairs (e.g. 31 . . . 36 in A2 and 37 . . . 42 in B2) being wound in interleaved fashion with a second set of turns (43 . . . 51 in A2 and 52 . . . 60 in B2), the interleaved turns extending over part only of the radial width of the coils and the coils being interconnected (at N) so that there is a non-inductive capacitative by-path from the starting turn to the finishing turn. The remaining turns of the winding (e.g. A6, B6) are wound conventionally. In some coils (e.g. Al, B1) the turns may be interleaved over the full width of the coils. The number of interleaved turns may decrease evenly from one coil pair to the next (Fig. 3, not shown). The line terminal may be connected to the inside turn of the winding. Instead of a single conductor two or more conductors wound in parallel may be used, the conductors being interleaved individually.

Filed: 1968-02-22
Abstract: 1,205,704. Delivering sheets. WINDMOLLER & HOLSCHER. 22 Feb., 1968 [22 March, 1967], No. 8683/68. Heading B8R. Delivery mechanism for bags having open ends or flattened bottoms, comprises two drums 1, 1<SP>1</SP> having grippers 2, 2<SP>1</SP> for delivering bags to stacks 15, 28. A given number of bags are stacked against a stop plate 11 and in front of a back plate 14 on two sets of rods 13, the gripper 2 being opened by a cam 7 carried on an arm 36. When the required number of bags is stacked, the front end of the stack being higher since it includes all the folded ends of the bags, a counter including a rotating cam 34 energizes a motor to lower arms 26, 27 which support the rods 13 on springs 24, 25, so that the stack is lowered to position 15<SP>1</SP>, while the pivotal movement of the arm 36 lowers the plate 11 so that teeth 44 thereof move out of grooves 3 of the drum 1 and inactivates the cam 7, so that the bags are carried by unopened grippers 2 and transferred to grippers 2<SP>1</SP> of the drum 1<SP>1</SP>, whereby each bag is turned over by passing round the drum 1<SP>1</SP> and delivered to a second stack 28 in a similar manner. A further motor is energized to drive chains 63, 64 and a pair of rods 61, 62 remove the stack 15 to a position 15<SP>11</SP> below the stack 28, whereafter the rods 13 are raised, and when the second stack is complete, the plate 11 is raised and the cam 7 rendered operative. The stack 28 is then lowered on to the stack at 15<SP>11</SP>, and on further movement of the chains, rods 61, 62 remove the combined stack, which becomes a single stack as its upper part 28 passes off the rods 13<SP>1</SP>, to a removing station, on the way to which belts 85 press on the top of the stack, which, owing to the opposite position of the higher end of the two parts, is parallelopipedal. The apparatus can be adjusted for different length and width of bags.

Title: Inductance unit
Inventor: KHOURI ALFRED SAFAY
IPC: H01C7/02
Filed: 1950-04-06
Abstract: 677,295. Radio receiving apparatus. GLOBEUNION, Inc. April 6, 1950, No. 8717/50. Drawings to Specification. Class 40 (v). [Also in Group XXXV] The tuned circuits in radio receiving apparatus comprise an inductance located on a former of a ceramic material having a temperture coefficient of dielectric constant equal in value but opposite in sign to its temperature coefficient of expansion. The inductance coil winding is preferably located in grooves in the surface of the former and may be deposited therein in any known manner such that it is positively locked to the former. If the ambient temperature increases the former and the winding expand thus increasing the inductance of the winding but, due to the negative temperature coefficient of dielectric constant, the self-capacity of the coil decreases and thus the circuit containing the inductance remains tuned at the desired frequency. The ceramic former may take any shape, e.g. tubular or flat, and the winding may alternatively be deposited on the surface thereof, but in this case the interturn capacity is not substantially all through the ceramic material of the former and the temperature compensation will not therefore be' so complete. A theoretical discussion is included in the Specification. Specification 608,579, [Group XXXVI], is referred to.

Filed: 1954-03-25
Abstract: 782,074. Magnetic tests. BARTLETT, E. E. [Personal representative of BARTLETT, C. (deceased)]. June 24, 1955 [March 25, 1954], No. 8759/54. Class 37. Apparatus for detecting cracks or flaws in a ferro-magnetic body by applying magnetic suspension liquid thereto comprises a frame, at least two upright supports on said frame for supporting the body to be tested, a currentconducting coil around each said support, and means for applying a direct current to said coils. In the embodiment shown, a rectangular casing 1/2 made up of frame 1 and closure walls 2 contain a test liquid reservoir 17 and drain 16 leading from sink 14. A guideway 3 straddles the upper and open end of casing 1/2 and cores 6 of coils 8 register in guideway 3 with test specimen 11 bridging V-blocks 12 engaging sockets in cores 6. To suit test specimens 11 of different lengths one core 6 is adjustable along guideway 3 whilst contact lug 10 of corresponding coil 8 makes sliding contact with bus-bar 9 which connects the two coils 8. A pump 22 driven by motor 19 propels test liquid from reservoir 17 to spray nozzle 29 which is slidable along a stirrup 27 above test specimen 11. In testing specimen 11 the nozzle 29 is adjusted to the required position and test liquid is pumped from reservoir 17 and is sprayed on to the test specimen 11  by nozzle 29 and returned to the reservoir 17 via sink 14 and drain 16. At the same time 2-way switch 36 (see Fig. 3) connects D.C. to coils 8 via full-wave rectifier 35 whereby specimen 11 is magnetized and iron particles in the test liquid bridge any crack in the specimen 11. When testing is completed switch 36 is changed over so as to apply A.C. from transformer 33 to the coils 8 and thus demagnetize specimen 11 and allow iron particles to drop off. The stirrup 27 may be swivelled away from the apparatus to facilitate replacement of test specimen 11. The Provisional Specification states that A.C. may be applied as a pre-testing step to remove any residual magnetism from the test specimen.

In an electric resistance analogue computer for solving a Poisson differential equation in which corresponding adjustable currents proportional to the LHS are supplied to a large number of nodal points of a resistance network conductive in co-ordinated directions, comprising a mesh of fixed or adjustable resistors, a conductive electrolyte, a conductive or semi-conductive sheet, or a combination thereof. The network comprises two or three systems of strips corresponding respectively to the coordinates and comprising plural elements in series, the nodes of which are connectible by multiplier switches to corresponding patchboard jacks for connection to current or voltage sources; the network being conductive in all co-ordinate directions. Each current is adjusted, proportionally to the derivative of a predetermined function according to the directional coordinate of the appropriate strip, and the nodal voltage then represents the integral of the RHS according to such co-ordinate; i.e. to that of a given function. In a two dimensional resistance analogue network, system D comprises a matrix of four strips, each comprising four series resistors disposed in the X direction, while system E comprises a similar matrix disposed in the Y direction. Arrays of switches or relays B, C are arranged to connect the respective resistor nodes to corresponding jacks of a patchboard A. When an electrolytic tank is used as a resistance network, it is divisible into strips by non- conductive separators, and alternatively two resistance media of film construction may be used, one undivided and one divided for current adjustment, with nodes switchable to patchboard jacks as before.

Title: Improvements in or relating to electrical frequency dividing systems
Inventor: SCHLESINGER KURT
IPC: H03B19/12
Filed: 1939-03-21
Abstract: 526,584. Valve circuits. RADIO AKT.-GES. D. S. LOEWE. March 21, 1939, No. 8950. Convention date, March 22, 1938. [Class 40 (v)] In a frequency divider the controlled low frequency oscillating system is made sensitive to synchronization by the higher frequency oscillation during only a short fraction of the period of the controlled oscillation, thus preventing errors in the phase or frequency of the divided frequency. The hexode valve has its anode back coupled by inductance 7 to the grid circuit 1, 2, which is tuned to the low frequency. The grids 4a, 4c, are coupled to the circuit 1, 2, by inductance 3 and phase shifting network 5, 6, in such a manner that anode current can only flow in the valve in short pulses corresponding to the period when both grids are positive. This time is made to coincide with one period of the higher frequency synchronizing oscillations which are applied from 10 to the screen grid 4d. The bias or grid 4d is normally so low that oscillation in the tube is prevented and is only possible during a positive period of the control oscillations. The system thus adjusts itself so that the positive pulse produced by the low frequency oscillations coincides with a positive half-wave of the control frequency. Negative potential pulses are obtained at the terminals of resistance 12, but a sinusoidal output may be obtained by the use of simple or coupled oscillatory circuits 13, 14, 13a, 14a. A number of such frequency dividers may be used in cascade particularly for obtaining a large number of lines in television; 441 for example is equal to the product of the four prime factors 7. 7. 3. 3. The invention is also applicable to systems in which the frequency is determined by resistancecapacity combinations. Specification 491,450 is referred to.

Abstract: 647,667. Tip-buckets. MINISTER OF WORKS. March 31, 1948, No. 9077. [Class 78 (iv)] [Also in Group XXXII] A skip, trough or like container is supported on crossed levers pivoted at their upper ends to the container and at their lower ends to a supporting structure so that the container is constrained to make a combined tipping and translational movement to discharge its contents, in which movement the edge over which the contents pass follows a path nearer the vertical than it would if the container were mounted on trunnions. As shown, a skip 2 for transporting concrete and other loose material on a building site is carried by pins 7, 8 loosely fitting in corresponding holes in links 4, 5 on each side of the container, which links are pivoted respectively at 10 to brackets 11 on longitudinals 6 of a vehicle chassis and at 9 directly to the longitudinals 6. A slot engaged by the pin 8 is provided to assist in dislodging the contents of the skips at the end of the tipping movement. The front wheels 12 of the vehicle are steerable and at the rear (not shown) of the vehicle is provided a driver's seat and an engine for driving the rear wheels. The centre of gravity of the skip may fall gradually during tipping, and a system of levers and rods operable from the driver's seat may push the skip as indicated by the arrow in the drawing to initiate tipping, or the skip may automatically tip when catches holding it are released. The skip may be prevented from tipping backwards or rattling by wedge-like rests. In an alternative construction the lower ends of the levers 4, 5 may be pivoted to upstanding steel plates secured to the outside of each member 6 and supporting steerable front wheels.
