Title: Improvements in or relating to the manufacture of covered boxes
IPC: B65D5/28
Filed: 1920-05-17
Abstract: 170,807. Smith, H. B. May 17, 1920. Covered boxes; apparatus for making boxes.- Covered paper &c. boxes are made up either from separately-cut body and cover blanks subsequently connected together by adhesive, or from continuous strips or webs of body and cover material which are caused to adhere together and are subsequently cut into blanks. The boxes are assembled around plungers or formers of the requisite shape, which are not illustrated. According to the first or " blank " method, a body blank s, Fig. 1, appropriately cut and scored and coated entirely on the underside and along the parts g, h of the upper surface with adhesive, is placed upon and caused to adhere to a similarly shaped cover blank as shown in Fig. 4, the central parts of the box end wing c heing, however, spaced away from the cover blank by the interposition of separators 1. The marginal edges of the cover side wings, which are wider than those of the body, are folded over on to the coated parts g. By gripping means 2, 3 the end wings c are lifted up away from contact with the cover blank and are maintained in position by rods 5, Fig. 5, or other means, the cover end wings l being held down by means such as fingers 6. The covered side wings are next folded up and their corner laps turned in by fingers 8 and caused to adhere to the end wings c, producing the appearance shown m Fig. 6. The cover end wings l, which have been coated with adhesive, by " offsetting " from the body blank, are finally turned upwardly and inwardly over the end wings c to complete the box. In the second or " web " method of assembly, strip w, Fig. 9, of body material and x of cover are fed from rolls, one surface, conveniently the upper surface of the cover web, being coated with adhesive. The body web before assembly with the cover is perforated with spaced rectangular apertures t and may be creased or scored as at f<1>, although the creasing &c. may be done after assembly of the web. As the webs advance from the rolls they are caused to adhere and the marginal edges of the cover, which is wider than the body web, are turned over on to the latter. Portions v indicated by dotted lines, are next cut from the united webs, leaving the boxforming elements connected only by cover material, further severances of which mid-way between the elements results in a series of covered blanks as shown in Fig. 10. These blanks differ from those in Fig. 4 in that the marginal parts w<1> of the cover end wings are coated with adhesivewhilst the adhesive coating h of the body end wings in Fig. 1 is lacking. The composite blank is set up as described above in connection with Figs. 1 to 6.

Title: Improvements in electric rectifying installations
IPC: H02M7/06
Filed: 1946-05-31
Abstract: 612,852. Rectifying; systems for charging batteries. PHILIPS LAMPS, Ltd. May 31, 1946, No. 16546. Convention date, March 9, 1942. [Classes 38 (ii) and 38 (iv)] A rectifier system, the output voltage of which varies only slightly with current over part of the range, but rises for low currents and suitable for charging batteries is formed by connecting in series or parallel the outputs of two rectifier arrangements, one of which has slight voltage variation for low loads and current limitation with high loads. Figs. 3, 4 show typical voltage-current curves resulting from the connection respectively in series and parallel of the output of an ordinary rectifier and a special rectifier system having respectively characteristics 2 and 16. The special system may comprise a rectifier supplied from a saturated transformer with a condenser in series with its primary, Fig. 5 (not shown), while the secondary of an ordinary transformer 21 may be in series with the secondary of the saturated transformer, Fig. 8. The output of two suitably designed figure 8 circuits may be connected in parallel, Fig. 10 (not shown), or the output of one such circuit may be in series with the output of a smaller rectifier supplied from a normal transformer with a premagnetized choke in its input circuit, Fig. 9 (not shown). To avoid the large volts drop resulting from the full current flowing through the smaller rectifier, this may be short-circuited at higher currents or the circuit of Fig. 11 may be employed. In this the Graetz connected drooping-characteristic rectifier system in which the current passes through two rectifiers in series, is replaced by the rectifiers 35 connected one to each end of a centre-tapped transformer 33. This results in full load current through the transformer secondary. Specification 562,638 is referred to. The Specification as open to inspection under Sect. 91 comprises also rectifier systems in which the two separate circuits are combined, to avoid the bad effects of the whole load current passing through the secondary of transformer 33, Fig. 12 (Cancelled), and Fig. 13 (Cancelled) (not shown). This subject-matter does not appear in the Specification as accepted.

IPC: A23L27/10
Filed: 1953-06-16
Abstract: 742,950. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 16, 1953, No. 16548/53. Class 106 (1). A record-card-controlled machine comprises means for feeding a plurality of packs of record cards past a plurality of reading stations, simultaneously each having means for reading data from the cards, a single means for printing the data, and switch means operable in synchronism with the feeding means to connect the printing means to the reading means at each of the several stations in succession. Two packs of cards 4, 3, Fig. 1, are fed through two sets of known sensing apparatus in parallel paths and the data sensed is employed to control printing means to print the data, e.g. addresses, on to two forms or paper tapes 5, 6 simultaneously. The paper tapes 5 and 6, Fig. 2, are fed by independent sets of pin wheels 11, 13, one above the other as shown. The tape 5 is folded as shown in Fig. 3 so that printing is carried out on the two portions 9, 10 only, while printing is carried out on the portions 7, 8 of tape 6 only, thus producing, after splitting, four forms 7, 8, 9, 10 as shown in Fig. 3a. The card feed is controlled by a clutch of known type shown in Figs. 4 and 6. Shaft 17 which is continuously rotating drives notched bushing 18. When magnet 88 is energized its armature 20 is attracted, thus freeing pawl 21 which, being drawn by its spring 22 falls into the notch of bushing 18. The pawl is then driven by the bushing so that part 23 on which the pawl 21 is mounted revolves in synchronism with shaft 17. The rotation of part 23 causes rotation of gear 24 which is fixed rigidly to it. The latter transmits its movement to feed rolls 25 through gears 26, 27 and 28. Specifications 523,832 and 618,267 are referred to.

Filed: 1941-12-23
Abstract: 555,671. Hydraulic couplings. CLEVELAND, F. J. (Hydraulic Brake Co.). Dec. 23, 1941, No. 16587. [Class 69 (ii)] In a hydraulic coupling of the fluid flywheel type comprising an impeller 78 with vanes 94 and a tutbine 100 having three sets of vanes 134, 146, 154, and also rectifying vanes 142, 152, and. reaction-vanes 174, 198, the vanes work in a torus 126 which is so designed that the fluid circuit is of uniform annular cross-sectional area so that there is a uniform fluid flow. The torus is built up from a radial section which has a central line in the form of an ellipse, and the actual form is determined on the principle that the width of the circuit at all points in radial section is inversely proportional to the distance from the centre of rotation of the driving- shaft 72 and driven shaft 102, and allowance is. made for the volumetric displacement of the vanes disposed within the passage. The driving- shaft 72 is driven from an engine by a universal joint and is mounted in bearings in a fixed sleeve 26 secured in a housing 20, and the impeller is splined to shaft 72. The operating fluid, is supplied from a reservoir to a manifold 62, and' a passages 56 leads from the manifold: to a balancing chamber 52 from which it passes via apertures 88 to the torus 126. The reaction vanes 174, 198 are secured to a carrier 160 mounted in an auxiliary fluid chamber 128 the wall 118 of which is connected to and rotates with the turbine. The chamber 128 is connected by passages 60, 58 to the compartment. 66 of the manifold'62 which leads to the inlet of the reservoir. At a predetermined; speed the flow of fluid in the chamber 126 changes and relative rotary motion between the carrier 160 and a threaded member 34 causess the carrier 160 to move to the right withdrawing the reaction blades and bringing into action vanes 186 which act as overdrive vanes, and the device then acts as a hydraulic coupling as distinct, from a torque converter: The motion of the carrier 160 is limited by dashpot devices. Cooling is effected by hoods 210, 214 supported-by vanes 208, 212 which permit passage: of air. Seals 74, 76, 108, 104 are provided to keep the parts fluid tight, and labryinth seals are provided to keep the parts of the chambers 52, 126, 128 fluid-tight

Abstract: 789,661. Tufting machines. ASPINALL, H. I. June 7, 1955 [June 8, 1954], No. 16768/54. Class 112 A tufting device comprises a canvas-supporting frame, a carriage movable along the frame, a tufting-hook mounted on the carriage and resiliently urged into a position such that it is projected through a hole in the canvas, and manually - operable means connected to the hook and adapted when operated, to withdraw the hook from the canvas. The device, as shown, comprises a pair of end-brackets 14, 16 carrying a pair of horizontal bars 10, 12 on which is slidably mounted a carriage 26. A rod 36, vertically slidable in the carriage is formed at its upper end with a hook 38 closable by a spring latch 40, the rod being biased upwardly by a spring 45 and being movable downwardly by a cable 44. The hooked-ends of a wire 66, which passes around a pair of pulleys 18 carried by the brackets 14, 16, serve to support a canvas net 64. A tufting operation is performed by depressing the canvas to a position, as at 68, to allow the hook 38 to pass therethrough. A piece of yarn is then looped around the upper end of rod 36, and the ends of the yarn are passed together over a side of a square of the net and through the hook. While said ends are retained by hand the rod 36 is lowered, when latch 40 is closed by engagement with the net, and the ends are carried through the loop to knot the yarn to the net. In a modification, the final part of the downward movement of the rod serves to actuate means for moving the carriage along bars 10, 12. The hook may be of the form described in Specification 789,662.

Title: Improvements in horns for acoustic instruments
IPC: H04R1/30
Filed: 1926-07-05
Abstract: 278,098. Voigt, P. G. A. H. July 5, 1926. Sound magnifying and directing appliances.- Gramophone &c. horns are designed so that the sound waves are expanding at any point as if the source wene at a constant distance from the point of expansion. For a straight horn cf circular cross-section, this is obtained by forming the walls to the shape of the curve known as the " tractrix " in which the length of the taugent between the point of contact with the curve and the central axis is a constant. For horns of square cross-section, the central longitudinal section is a tractrix, or alternately, for horns of square or any other cross-section, the area at any point is made equal to the area of the corresponding circular horn based on the traetrix. Bent horns as shown in Fig. 2 are obtained from the basic straight horn a, e by dividing the latter into transverse sections h, g, f, f<1>, f, b, b<1>, j<1>, &c. which are bent separately about centres i<1>,i<2>, &c. in a manner fully described in the Specification so as to form corresponding sections h, g, n, n<1>, n<1>, n, r, r<1>, &c. of the final bent horn. The use of different centres i', i<2>, &c. minimizes the difference of phase introduced by the difference in length of path around the bend. An alternative method of avoiding phase-displacement around the bend is to split the horn into two sections, as shown in Fig. 3, each section being bent about fixed or variable centres (indicated by crosses), and the inner section being bent back on itself so as to provide a length of path equal to that through the other section. In Fig. 3, the lower half of the horn is suppressed and the imaginary centre line of the complete horn is continued in a member 5, 6.
