Title: Method of marking labels, wrappers, cartons, or the like
IPC: B41K3/36
Filed: 1929-10-12
Abstract: 339,724. Gibson, C. Carew-. Oct. 12, 1929. Circular-saw machine.-A machine for forming a series of nicks or cuts along the edges of labels, wrappers, cartons, neck bands, banderoles, or the like, or order forms of cheques to act as indicating marks, is provided with a number of saws axially adjustable on a common axis. In one form the labels are carried in a clamp 8, Fig. 1, slidable on a guide 11 beneath an axis 4 carrying saws 6 spaced by washers 7 according to the data to be indicated. The bearings of the axis are adjustable in side frames 2 to enable the depth of cut to be regulated. In the form shown in Figs. 3 and 4, the saws are mounted on an axis below the table 14 and project through an opening 31 therein, the clamp 8 being slidable in a guide 13. The base of the clamp is slotted to form a guide for the movable jaw 28 of the clamp, and a part 20<1> of the table projects into the slot for the purpose of supporting narrow labels. The jaw 28 is provided with a handle 25 connected by a link and pin-and-slot connection to the jaw to facilitate the clamping of the labels against the jaw 22 which is under the influence of a spring 35. The shaft 4 carrying the saw may be power operated or may be rotated by rack- and-pinion mechanism from the slidable clamp. If the shaft is driven by an electric motor, the movement of the clamp may control the starting- switch. A catch may be provided to hold the carrier after it has passed the saws. The shaft may be mounted in an eccentric bush to enable the depth of cut to be regulated, or the fixed jaw of the clamp may be provided with an adjustable bracket for supporting the labels. To enable curved labels to be cut, a key having curved faces may be mounted in a slot in the shaft, or one cutter only may be employed, the labels being passed under the cutter the requisite number of times. The shaft may be provided with an eccentric portion or with a key, and the saws formed with a cutaway section to enable any of them to be put out of use, in which case the washers may also be cut away or provided with notches to effect balancing. In some cases, the saws may be provided with a number of separate peripheral cutting-portions of different shapes. Th jaws of the clamps are preferably lined with wood, fibre, or other material through which the saws cut to prevent damage to the outer labels.

Abstract: 1,058,634. Block bottom bags. J. G. WILLETTS. Nov. 15, 1963 [Aug. 15, 1962], No. 31302/62. Heading B8K. A rectangular blank folded about a transverse score line 1, Fig. 3, has isosceles triangular areas 8 defined by score lines 7 tucked in, and wings 5, 6, Fig. 1, defined by score lines 4 folded out to produce the formation shown at the right-hand side of Fig. 1. Flaps 11, 12 are then folded about score lines 9, 10 and secured by adhesive 17 to give the formation shown at the left-hand side of Fig. 1. The flaps 11, 12 form the ends of the bag when it is erected, Fig. 10, score lines 13, 14 defining the edges of the flat base. Cut-outs 15, Fig. 1, in the areas 8 enable the flaps 11 to adhere to strips of adhesive 16 on these areas. Hand holes 18 reinforced by cards 19 are provided at the bag top. In a second embodiment, Fig. 4, the lower ends of the flaps 11 are tucked beneath the areas 8 and their edges 22 lie adjacent fold lines 10 so that the triangles 8 do not form pockets within the bag. In this embodiment notches 21 replace the cut-outs 15, and no hand holes are present. In a further embodiment the bag bottom is tucked in along lines 13, 14 to form a gusset when the bag is flat. In any embodiment when the bag is square only one score line 4 is necessary. The score line 1 may be displaced so as to produce a bag deeper on one side than the other.

[Class 12 (ii).] In valve gear for internalcombustion engines comprising a cam 2 actuating a pair of inlet or exhaust valves 7, 7a through a T-shaped tappet 4, 11, the tappet is prevented from rotating by forming the guide portion 11 with flats 4a at its upper end engaging corresponding flat guides 12a. The guiding surfaces are lubricated by oil supplied through the hollow cam shaft and through a radial bore in the cam to an orifice in the top of the tappet leading to the hollow interior of the guide 11. The oil collects in a cap 19 fitted over the bottom of the guide, and is forced up a groove on the outside of the part 11. In a modification, the cam shaft extends at right-angles to the heads 4 of the tappets, the guides being then lubricated through bores extending through a cam-shaft bearing arranged between a pair of tappets.

In an apparatus, for separating solid particles from a stream of air or other gas, which comprises a band of filter cloth 2 enveloping the gas-permeable cylindrical wall of a drum 1 which is arranged in a box-like casing 3, the filter band is caused to travel from idler spool 7 around the drum by driven spool 8, these spools are arranged in separate box-like housings 9, 10, the casing 3 is constructed of separate walls 4 and, in course of manufacture, the apparatus is arranged either for radial flow of gas through the drum (see the arrows on Figs. 1 and 2) or for axial flow (Fig. 4). For radial flow, both ends of the drum are closed by the casing, a space 6 is left between spool housings 9 and 10; and the top wall of casing 3 is omitted. For axial flow (see Figs. 3 and 4) the spool housings are close together; one end of the drum is open, and the end walls of the casing 3 are omitted. The gas stream may be conducted through the apparatus in the opposite direction to that indicated by the arrows. Fig. 5 shows a modification wherein the casing is in the form of a rectangular section duct 3'; and wherein the side walls 15 and 16 of housings 9 and 10 are arched to form a gas exit channel 6 which approaches a nozzle shape. The drum may be stationary, but is preferably rotary. The drum may consist of a cylindrical steel wire grid extending between two end rings. A scraper blade may be provided for removing solid material from the filter band (Fig. 13, this and the further Figs. 14 to 21 referred to below are not shown). The motor for the driven spool may be controlled by a pressure-difference manometer for regulating the speed of travel of the filter cloth according to the pressure conditions existing in the apparatus. A throttling louvre may be provided at the gas entry side of the drum (Fig. 14). Several drum filters may be joined together, horizontally or vertically, to form major assemblies (Figs. 15, 16, 17). A fan may be disposed between the spool housings (Figs. 18 and 19) or within the drum (Figs.20 and 21).

Title: Stepping motor system
Inventor: WALLIS CHRISTOPHER NORMAN
Filed: 1967-07-11
Abstract: 1,135,970. Electric motors. INTERNATIONAL BUSINESS MACHINES CORP. 11 July, 1967 [31 March, 1967], No. 31746/67. Heading H2A. In the stepping motor control system shown in Fig. 3 of Specification 1,068,972, hunting of the rotor when it reaches the desired position is reduced by connecting a series resonant circuit including a capacitor across at least one of the pole windings of the motor. The motor has pole windings I, II, III, IV which are sequentially energized in pairs according to the energization state of photo-sensitive elements P3, P4 which are illuminated through slots in a mask mounted on the rotor shaft. In operation when the desired position is reached, circuitry 200 sets bi-stable flip-flop 106 to provide an output on line 137. This output enables gates 140, 142 to energize two of the windings and provide a locating torque on the rotor. Each pole winding has a series circuit comprising capacitor (201-4) and reed switch contacts (205-8) connected across it, the switches being closed by energization of coils (209-212) by the signal on line 137. When the switches are closed the capacitor and winding provide a resonant circuit which may be turned to provide optimum damping. In a modification, Figure 2 (not shown), the coils are supplied through gates which are enabled by the signal on line 137 and the current flowing in a non-associated pole winding, so that the switches are only closed for windings which are not energized.
