Title: Improvements relating to machines for forming bent wire clips or rings
IPC: B21F33/04
Filed: 1932-11-12
Abstract: 411,830. Stapling. RHODES, J. W., and BINCH, A. H., c/o Rhodes, Ltd., Lotus Street, Nottingham. Nov. 12, 1932, No. 31994. [Class 89 (iii).] A machine, particularly for connecting the end coils of adjacent springs of a pocketed spring mattress, is arranged to cut successive pieces from a length of stock, and to bend them substantially to diamond form to embrace said coils. Wire 21 is fed across a saddle 13 beneath two formers 10, 11 which are, respectively, pivoted and fixed to a cross-head 12. When the cross-head descends, the former 11 cuts off a length of wire in co-operation with a guide 22, and both formers bend the wire to U-form about the saddle, Fig. 4. Upon continued descent of the cross-head, the saddle is withdrawn, the U-shaped clip is carried down to embrace the coils of the springs positioned beneath it, and the former 10 is swung about its pivot by an adjustable stop 36, when permitted by a recess 37 in the former, to bend the clip 24 to diamond form, Fig. 6. It then locks the spring coils 22<a>, 22b, with or without penetration of the fabric 23 forming the pockets. The cross-head is forced down, against springs 17, by a cam 18 on a shaft 42 driven by reduction gearing from a pulley shaft 41. The wire is fed by a slide 26 and a dog 28 pivoted to it. When the dog is rocked by a lever 32, it first grips the wire and then carries it forward. On its return movement it releases the wire, a spring-pressed dog 30 preventing retrograde movement of the wire. The extent of the feed movement of the slide 26 is determined by an adjustable stop 38. The wire-feed lever 32 is operated from a cam 43 on the shaft 42 through linkage 52, 51, 50 Fig. 8, and a rock-shaft 47 and cam follower 48. A third cam 46 on the shaft 41 reciprocates the saddle 13 through linkage 55, 56, 58 and a gear segment 59 and rack 61. The frame 16 carrying the stapling mechanism is suspended by posts 64 above a table, not shown, on which the mattress is positioned. In making up a pocketed mattress, a chain of open-ended pockets is formed in a strip of fabric, a compressed spring is inserted into each pocket, the ends of the pockets are closed by sewing, each spring is turned through an angle of 90‹, a plurality of such chains are assembled side by side, and the end coils of adjacent springs are connected by clips, Fig. 10, as described.

Title: Self-processing film unit
IPC: G03C8/42
Filed: 1973-07-05
Abstract: 1433604 Self-processing cameras and film units EASTMAN KODAK CO 5 July 1973 [5 July 1972 (2) 10 July 1972] 32058/73 Headings G2A and G2X  In a self-processing film unit 15, in which processing material from a container 17 is spread between a photo-sensitive sheet 20 and a transparent second sheet 22, a stiffening bar 38 extends transversely across the carrier sheet 19 adjacent the leading edge of the container 17. This serves to resist bowing of the container in the transverse direction without interfering with its flexibility in a direction at right-angles thereto. The bar 38 may be made of sheet metal, bent round and crimped to the leading edge of the leading end portion 23 of carrier 19, or it may be a thickened edge moulded or otherwise integral with the carrier sheet Figs. 4-6, (not shown), and may also have a downwardly curved profile Fig. 22 (not shown). In operation, the film unit is advanced towards the nip between a roller 76 and a shoe 78 by pulling on a spring-loaded operating bar 100, which moves a feeder member 90 from the retracted position of Fig. 9 to the extended position of Fig. 10. (Alternatively an electric motor may provide the motive power). Shoulders 102 on arms 96 of member 90 engage behind the ends of the bar 38 and pull it into the nip between roller 76 and shoe 78. Sprocket teeth 82 on roller 76 then engage in perforations 36 in carrier sheet 19 and convey the film unit onwards. The bar 38, container 17 and sheet 19 are carried round roller 76, and guided by shoes 86 into the wastecollecting compartment 54 in the rear part of the camera. Thus sheet 19 is stripped away from the image-recording sheet 16 whose inherent stiffness causes it to continue in a straight line and pass out of the camera through a slot in the wall. Since the roller 76 cannot convey the waste carrier sheet all the way into compartment 54, a retracting member 106, operated by a handle 114, completes the movement by means of a pair of claw fingers 108 which extend into compartment 54 and engage the ends of the stiffening bar.

Title: Cathodic protection systems

Filed: 1964-08-06
Abstract: 1,071,737. Automatic control systems for cathodic protection. N.V. APPARATENFABRIEK PLAISIER. Aug.6, 1964, No.32061/64. Heading G3R. A cathodic protection system for a hot water container comprises an electrode 4 in the container 3, the electrode 4 being fed from a transformer 2 by way of a rectifier 1 and a transistor T1 having its collector connected to the electrode 4 and its emitter connected over resistors 5, 6 to the positive terminal of the rectifier 1, the negative terminal of which is connected to the container 3. The base of transistor T1 is connected to a voltage divider 7, 8, 9 connected as shown. In operation, an increase in the protection current above a desired value results in an increase in the voltage across resistors 5 and 6 so that the base of transistor Tl becomes more positive with respect to the emitter whereby the transistor passes less current to counteract the increase; a decrease in the protection current below the desired value will similarly result in an increase in the collector current of transistor T1. The transistor Tl may be controlled by a second transistor Figs. 2 and 3 (not shown), and the system may include a sensing cell which detects any change in the protection current Figs. 4 to 6 (not shown).

Abstract: 1,236,466. Pumps operating by electromagnetic interaction with fluids. KAISER ALUMINUM & CHEMICAL CORP. 9 July, 1968, No. 32665/68. Heading H2A. An electromagnetic induction pump has an annular coil 10 having a depending central core 24 supported on a beam 32. The core and coil is enclosed in a shell 36 and depends into a bore in the pump body to form an annular conduit 12. Fluid enters conduit 12 from reservoir 16 through channels 14, neither the reservoir nor channels forming a complete loop around the coil so that back pumping will not occur. The ratio of the outer diameter to inner diameter of conduit 12 should lie between 1À01 and 2 in order to obtain optimum pumping. The actual internal diameter should be not less than half the internal diameter of the coil and the external diameter not greater than twice the external coil diameter. In operation A.C. is applied to coil 10 and its magnetic field interacts with the magnetic field set up by the liquid in the conduit, acting as the secondary of a transformer, to drive the liquid down to outlet 18.

Abstract: 1,198,984. Character recognition. HAWKER SIDDELEY DYNAMICS Ltd. 19 July, 1967 [21 July, 1966], No. 32904/66. Heading G4R. [Also in Division G2] In amethod of recognizing images or characters, each subject to be recognized, constituting one of a set of known subjects, has its diffraction pattern thrown on to a matched holographic filter for each of the known subjects, the filter for any known subject having been modified in manufacture by means of information relating to the other known subjects so as to cause the filter to reject the other subjects at least to some extent. As described, the holographic filter for a given subject is obtained by prefogging a photographic film or plate to get it on to the linear part of the transmissivity/ exposure curve, then exposing it for a time T to the given subject and a reference beam to produce a Fourier-transform hologram, then exposing it in turn to the other subjects in a similar way. In the cases of the other subjects the exposure times (expressed as a ratio with T) and the relative phases of the subject-illuminating beam and the reference beam (the same as with the given subject or 180 degrees different) are chosen so that the final filter obtained after development gives maximum discrimination between the given subject on the one hand and other subjects on the other. Equations indicating the required exposure ratios and relative phases in terms of the auto and crosscorrelation functions between the subjects (which may be calculated or measured) are given. T is chosen so that the total exposure does not take the plate or film off the linear range.
