Title: Cigarette packaging machine
IPC: B65G47/248
Filed: 1977-03-17
Abstract: Said apparatus comprises a single raising means (68) for forming single successive piles each consisting of a predetermined number n of articles and a pair of thrusting means (71, 75) moved in synchronism with each other at a frequency equivalent to 1/n of that of said single raising means (68). One of said thrusters (71) feeds successive single piles to a horizontal wheel (74) having a device (82) for discarding and replacing defective piles and the other (75) removes in sequence said piles from said horizontal wheel (74) and feeds them into a respectively adjacent position in single groups (79) to a channel (76) for feeding to the packing or box-filling machine. With this apparatus, therefore, it is possible to obtain groups of articles, each formed by a plurality of adjacent piles, all complete with the same number of articles and without the omission of any operating cycle. In particular, the apparatus is supplied with packets of cigarettes from a cellophane-wrapping machine, so as to obtain parallelepiped groups conveyed to the packing or box-filling machine. <IMAGE>

Title: Improved rubber stereotype plates for rotary printing machines
IPC: B41N1/12
Filed: 1956-04-16
Abstract: 798,337. Laminates. ARCHER, A. J. March 25, 1957 [April 16, 1956], No. 11464/56. Class 140. [Also in Group XVI] A rubber stereotype plate has a material incorporated therein, the material being such that shrinkage due to vulcanization is prevented or minimized in the direction extending axially of the cylinder on which the plate is subsequently to be mounted while leaving the rubber free to shrink in the direction extending circumferentially of the cylinder, so that shrinkage due to vulcanization and the stretch due to attachment to the cylinder tend to counterbalance each other and the printed result is the same size in both directions as the original type forme. The material used is preferably a fabric having weft threads stronger than the warp threads and located closer together. In cases where the shrinkage due to vulcanization is not sufficient to counterbalance the subsequent stretching the plate 4 may be precontracted by passing it over a former 2 having a smaller radius of curvature than the printing cylinder. To this end an inert material 3 having adhesive thereon is tensioned around the former 2 and a roller 1 of the same diameter as the printing cylinder. The plate 4 is led over a guide 5 and stuck to the material 3 on the former 2. After the whole plate has been so secured the material 3 with the plate 4 is removed from the roller 1 and any surplus material trimmed away.

Title: Electronic adding system
IPC: G06F7/491
Filed: 1962-03-28
Abstract: 990,557. Electronic computers. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 28, 1962 [May 3, 1961], No. 11823/62. Heading G4A. A parallel adder, operating on binary-coded decimal digits, is built from stroke blocks 901 (Fig. 9a). The code used is 2-out-of-5 from bits weighted 0-1-2-3-6. The bits of corresponding digits of the addend and augend are sampled to form "summation functions". An or function P has the value 1 when at least one of the i-weighted bits of a pair of corresponding digits is one. An and function Gi has the value 1 when both the i-weighted bits have the value one. Of the ten summation functions of a pair of five-bit digits four and only four have the value 1 for any decimal values (Gi = 1) implies Pi = = 1). A set of summation functions defines the sum of two decimal digits. One order of the adder is shown schematically in Fig. 3. X and Y bits are applied to a summation function generator 308. At the output redundant functions are eliminated, but in the generator a check is made that 4-out-of-10 functions have the value 1. The output of generator 308 is a "raw" sum and the carry from a lower order is combined with the raw sum in circuit 310. The output of generator 308 is also used in digit lookahead circuit 303 together with a not-zero signal to determine independently if the raw sum is 9 or greater, or 10 is greater. In the group lookahead circuit 12 this information from four orders, together with the in-carry into the lowest of the four orders, is used to derive carry signals for the four orders. These carry signals are checked against carry signals derived from circuits 309, 310. In the stroke block 901 two transistors are shown since circuit characteristics necessitate a maximum of three inputs to each transistor. Only the inputs X0 and T are available in the particular application of Fig. 9a and only the operation of transistor 902 is affected. When transistor 902 is non-conducting output terminal 906 is at -s volts. If at least one but not all of the inputs are at -s volts the output terminal is raised to ground potential. The function combiner 309 (Fig. 13 not shown) has the ability of dealing with the exponents of floating point numbers which occupy the two highest order positions of a data word. An exponent of 50 represents a number with decimal point immediately to the left of the highest significant digit. A combination of two exponents requires an additional control signal. Detailed logical diagrams for all the circuits are given.

A machine for honing a curved surface A comprises a tool F having a small area relative to the surface to be honed and driven with a rapid periodic abrasive motion, a housing U for the tool resting under its own weight and via the tool on the surface to be honed which surface is fixed to a mount B rotatable about a vertical axis, the tool being movable at a slow rate transversely of the axis. The curved surface may be on a metal, ceramic or glass piece A secured to the mount B which is rotatable by gearing C, D and a belt-driven pulley E and is vertically adjustable so that the mean centre of curvature L of the surface to be honed is in the same horizontal plane as the axis of rotation u, u<SP>1</SP> of a chassis I connected by pairs of links J, K to the housing U for the spindle H of the tool which is rotated by a flexible shaft S from a motor R mounted on the chassis. The tool F is given a rapid abrading motion by an eccentric pin G which is driven by the spindle and is axially-adjustable to bring the links J, K approximately horizontal. The tool is slowly traversed across the surface while driven with the rapid abrading motion by the action of a follower M carried by the chassis I engaging a cam N chain driven through a reduction gearbox O. The links J, K may be of equal or different lengths and the connections of the links to the housing and chassis arranged so that the links may or may not be parallel. The pivot u, u<SP>1</SP> of the chassis may be between or above the points of connection between the links and chassis. The various arrangements permit surfaces which may be convex or concave and may or may not be spherical to be honed. Abrasive is supplied to the tool through a pipe W and may be collected in a bowl X and fed to the tool by a pump. The machine may impart a vibratory motion to the tool in place of the circular abrading motion.
