Title: Improvements in or relating to wrapping and labelling machines
IPC: B65C1/02
Filed: 1925-10-09
Abstract: 269,835. Marks, E. C. R., (Package Machinery Co.). Oct. 9, 1925. Labelling.-Relates to machines for wrapping and labelling articles such, for instance, as are described in Specification 269,246, [Class 94 (i), Packing &c.], and in which the progress of the article through the machine is effected by a transporter member, and a label is applied before the article is discharged. According to the invention, delivery belts are provided which are actuated so as to move through a distance less than that of the transporter at each feed movement but to be moving at substantially the same speed as the transporter at the moment of taking a packet. As shown, the articles are moved from positions I - - VI, Fig. 3, by a transporter comprising frames 30 with vertically depending fingers A - - F, into engagement with belts 36 running round vertically mounted pulleys 394, Fig. 1. Positioning plates 390, ribbed at the top and bottom, so as not to touch the labels, ensure the correct entry of the packets. The transporter is actuated from a shaft 260 by a chain 230 to rotate cranks 242 connected with links 234, 236 so that it moves forward substantially horizontally and is raised and retracted so as to engage a finger behind each succeeding article. At each successive step, wrapping and labelling operations are effected. In order that the wrappers or labels may not be disturbed, the belts 36 travel at the same speed as the transporter towards the end of the transporter stroke, but during the remainder of the intermittent travel, move at a slower speed so that the packets are in contact between the belts, whereas the packets are necessarily spaced during the operation of the transporter. The belts are driven by the mechanism shown in Figs. 1 and 2. The shafts 398 carrying the pulleys 394 are driven by bevel gearing 400, 402 from a shaft 404 carrying a ratchet 406. A pawl 408 on a rocker 410 is actuated by links 412, 414 from an oscillating arm 370 which drives the shaft 364 actuating the label applying apparatus, which is actuated from the transporter shaft. During the first part of the movement of the rocker 410, it is held by a spring 422 into engagement with the link 414 so that, in effect, the parts 410, 414 act as a rigid arm longer than the arm 370. Towards the end of the stroke when the arms 412, 414 have been straightened out, they act as a single link, and the rocker 410 and the arm 370 rotate at the same speed. The ratchet 406 is provided with five teeth and the ratchet 366 with three so that the total travel of the belts is less, at each intermittent motion, than that of the articles in the transporter.

Title: System and method for monitoring a press load
IPC: B30B15/00
Filed: 1974-02-19
Abstract: 1451401 Measuring press load electrically ALUMINUM CO OF AMERICA 19 Feb 1974 [26 Feb 1973] 7540/74 Heading G1N A method of monitoring the load on a forming press comprises mechanically sensing the position of a ram and generating representative electrical signals; generating therefrom further signals representing a predetermined strain as a function of ram position; mechanically sensing the actual strain on the press apparatus and generating representative signals; and comparing the actual and predetermined strain-responsive signals. The angular position of a crank-shaft 16 which drives, via a connecting rod 17, a ram 4 of a fourcolumn forming press 1, is sensed by a servogenerator 28 coupled to the crank-shaft 16 by pulleys 24, 22 and a chain 21. A servomotor 30 mounted remotely from the press 1 and electrically connected to the generator 28 reproduces the angular position of the generator 28 and drives a shaft encoder 34 which may comprise an apertured disc with a lamp and photo-cell. The shaft encoder 34 output is led to a D-A convertor 36 which provides an analogue signal representing the displacement of the ram 4; and a piecewise-linear function generator 38 comprising an adjustable diode resistor network converts the analogue signal into a signal representing the tolerable strain in the press columns as a predetermined function of the ram 4 displacement. At least one strain gauge 40 attached to at least one press column, e.g. 9, is connected to an amplifier 45 providing an actual-strain signal which is compared at 43 with the tolerable-strain signal. If at any stage during an operative cycle the actual strain exceeds the tolerable strain the static switch 44 is excited to supply a warning light or bell and to prime the switch 46 so that at the end of that cycle a cam limit switch driven by the shaft 26 provides a signal to disengage the clutch 19 and apply a brake 20A. Instead of the displacement sensing arrangement illustrated, there may simply be provided a potentiometer attached to the press frame and actuated by the ram 4 to provide an analogue signal directly applicable to the function generator 38.

Title: Improvements in or relating to television circuit arrangements
IPC: H04N9/20
Filed: 1959-03-04
Abstract: 912,245. Television; resistance networks. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 4, 1959 [March 7, 1958], No. 7546/59. Classes 40 (3) and 40 (8). The background brightness of the picture reproduced by a television picture tube employing at least two electron guns is controlled by an adjustable bias voltage for each gun derived from individual resistors the voltage across which and the voltage at a given point of which are independently adjustable, the arrangement being such that the bias voltage for each gun may be varied by the same amount with respect to the voltage at the given point by means of a single control member. Fig. 2 shows one embodiment applied to a three-gun colour picture reproducing tube in which the bias voltage for each gun is derived from individual resistors 7r, 7g, 7b, the sliders of which are ganged together to permit adjustment by a single control means. The voltage drop across the resistors 7 is maintained constant by voltage stabilizers 8 so that adjustment of the ganged sliders 6r, 6g, 6b to vary the background brightness produces the same bias voltage change on all guns independently of the actual voltages. The latter may be varied individually for each gun by means of resistors 9r, 9g, 9b to compensate for differences in cut-off voltages and, additionally, by means of resistors 4r, 4g, 4b to compensate for differences in mutual conductances. Fig. 3 shows a second embodiment in which the voltage stabilizing devices are replaced by ganged differentially operating variable resistors 14, 15 (r, g, b) adjustment of which is for cut-off voltage compensation does not vary the voltage drop across the resistors 13 (r, g, b). The general theory of the arrangement is described in connection with variable resistors in series with, adjustable, constant current and constant voltage sources (Fig. 1, not shown).

Abstract: 152,576. Plummer, W. E., Kermode, W. M., and Plummer, C. St. C. March 15,1920. Stuffing-boxes, substitutes for.-Relates to means for preventing leakage between rotating and stationary elements of the kind in which the packing rotates with the shaft and a joint is made between radial rubbing surfaces. Fig. 1 shows the invention applied to a centrifugal pump. The packing is held by a spring-pressed gland in a box 4 which has teeth 8 engaging similar teeth on a split ring 7 clamped about the shaft so as to rotate with it. On the end of the box is secured a ring 9 of antifriction metal &c. rotating on a ring 10 having a spherical seating on a ring 11 bolted to the pump casing. The ring 10 can rock but is non-rotatable, and the rubbing surfaces are lubricated through a passage shown in dotted lines. The ring 7 rotates on a ring 14 of antifriction metal &c. secured to a ring 15 held by studs 16 and adjustable by nuts to stress the springs 6 before the ring 7 is finally clamped on the shaft. In a modification, Fig. 3, the box 4 has a spherical seating on a ring 19 which carries an antifriction ring 20 running on the ring 22. The ring 20 may be tapered to fit a correspondingly tapered recess in the ring carrying it. In a further modification shown in Fig. 5, there is only one radial surface, and the rotation of the spherical ring 24 is limited by a key 23.

In a method of increasing the operating speed and improving the back washing effect of a wet treatment process, the material being treated is squeezed at least once below the level of liquid in a bath, in such a manner that the liquid boundary layer surrounding the material is only partly destroyed during the squeezing process. In the arrangement shown material 1 is fed into a bath 4 around a screen drum 2 with a number of squeeze rollers 6 pressing there-against, and then out of the bath and between a pair of press rollers 7, 8. At least one of the rollers 6 is, for example, a serrated roller or a roller with helical and or axial recesses of any kind so that some liquid passes with the material between the rollers. Alternatively two rollers with toroidal projections may co-operate, the projections facing each other or being in an offset relationship. Further the rollers may consist of individual segments, alternate segments being larger and smaller, or there may be a plurality of circumferential grooves in the roller surface. The squeeze roller may be adjustable in height and/or laterally so that their position can be varied. The liquid squeezed out of the material by rollers 7, 8 may pass back to the bath 4 along the material or it may be collected in a separate tank which is connected to the main bath 4 through a non-return valve and a suitable pump operated by the liquid level in the separate tank.

Title: Improvements in or relating to radar systems
Inventor: RODGERS JOHN
IPC: G01S7/12

Abstract: 780,211. Radar. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 16, 1955 [March 17, 1955], No. 7777/55. Class 40 (7). In a radar system having an angularly movable directional aerial of the type in which the direction of maximum sensitivity in the plane perpendicular to the axis of movement varies, relative to the aerial structure, in dependence on any variation of signal frequency, difficulties are encountered due to any change in the frequency causing angular errors in the P.P.I. display or other utilization means. So that such errors may be easily corrected, if necessary without shutting down, differential adjusting means are incorporated in the synchronizing connection between the aerial drive and the utilization means. As shown in Fig. 1 the aerial 1 is of the slotted waveguide type and is mounted on a shaft 3 for rotation by a motor 4. Movement of the scan in the P.P.I. display tube 5 is synchronized with the aerial rotation by means of a Selsyn type link including a first transmitter, with the rotor 7 mounted on the aerial shaft, a first receiver, having a rotor 9 driving one sunwheel 15 of a mechanical differential, a second transmitter, having a rotor 11 driven by another sun-wheel 16 of the differential, and a final receiver whose rotor 13 is connected to the indicator deflection system. The planet-wheels of the differential are carried by a cage having external teeth co-operating with worm 19 controlled by adjustment knob 20. Setting the knob 20 so that the frequency of the signals being radiated is indicated on scale 22 is arranged to introduce the required angular compensation between the drive and driven elements of the differential to correct for variation in aerial directivity due to change of frequency. The mechanical differential may be replaced by an equivalent electrical device; for example the knob 20 may be arranged to angularly adjust the position of stator 12 of the second transmitter, the rotors 9 and 11 being directly coupled (Fig. 2, not shown). Although the compensating arrangement is described as located in an intermediate position it may be placed either at the aerial or display and a single Selsyn system only need then be used.
