Title: Improvements in and relating to wrapping machinery
IPC: B65B51/02
Filed: 1955-04-25
Abstract: 827,588. Wrapping-machines. DORTON, E. W. July 23, 1956 [April 25, 1955], No. 11877/55. Class 94(1). In a machine for wrapping rectangular articles or stacks of such articles, the articles B are placed one at a time at the loading position A, are partially wrapped whilst being moved on to an elevator 4 which then rises, wrapping the articles further and applying an adhesive to the wrapping material from a tray 7. The articles are then moved to the right onto a conveyer 10, final wrapping and glueing taking place during this movement. A platen 3 moves each article to the left along a support as shown in Figs. 1, 2, and the elevator 4 descends, operating a guillotine blade 12 to cut off a section 3D of the wrapping material which is fed forward by a roller 14. As the elevator 4 descends, pressure rollers 15, 16, close together and so hold the wrapping material in the position shown in Fig. 2. The article is then moved onto the elevator 4 and the suspended part of the material CD is wrapped over the top, the left hand end and part of the base of the article is in Fig. 3, whilst vertical sideplates 4a perform a first end folding operation on the material. The elevator 4 then rises and a first glueing means 7 operates to apply adhesive to the end C of the wrapping material and the right-hand end of the article is wrapped, the material being drawn under tension from the rollers 15, 16. When the elevator 4 reaches its upper position, a pusher member 6 moves the article along a channel way 2, thus drawing the trailing end D of the wrapping material under the article to overlap and be secured to the glued part C. Vertical side plates 2a then perform a second end folding operation on the material projecting at the right hand end, thus forming horizontal upper and lower flaps 5a, 5b. At this stage, adhesive is applied by a second glueing means 8 to opposite sides of the article, to subsequently secure the flaps 5b which are folded by guides 2b. While the article is at this position, third glueing means 9 apply adjesive to the underside of flaps 5a which are folded down by guides 2c. The packaged article then passes between endless conveyers 10 driven intermittently to move the complete packages stage by stage in synchronism with the other operations described. The machine may be provided with suitable adjustments to use is for wrapping packages in a preselected range of sizes. The folds may also be made in four movements by first folding left hand end as above, then the upper edge whilst rising on the elevator, then the right hand end and finally the lower edge on the channel way. All moving parts are driven by link motion from a common cam shaft driven by a motor.

Filed: 1974-03-19
Abstract: 1462701 Control systems for X-ray apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 March 1974 [22 March 1973] 12152/74 Heading H2H The period for which a switch in the primary circuit of an X-ray H.T. supply transformer is closed is made longer than the X-ray exposure period, the prolongation of the period being made dependent upon the current through the X-ray tube. At the instant the switch in the primary circuit of an X-ray transformer is closed a pulse is applied to a timing device 1 by way of a line 2. The period for which the switch remains closed is determined by the resistance which exists between the points 4, 5. This resistance is made up of two elements, a resistor 6, the value of which is dependent on the chosen exposure time and one or more of resistors 7a, 7b, 7c chosen by operation of switches 8a, 8b, 8c according to the desired tube current. Further resistors 7d-7f may be employed when it is required that the tube operates at a constant power, these resistors being inserted into circuit by means of switches 8d-8f, the arrangement being such that the value of resistors 7d-7f decreases as the tube current automatically decreases when the voltage applied to the tube increases. At the end of the time determined by the resistors, which time represents the exposure time plus a time dependent upon the tube current the timing device 1 emits a signal on line 3 to open the switch in the primary circuit of the X-ray H.T. supply transformer. In other embodiments the tube current is measured and compared with a linearly increasing current generated by a monostable flip-flop circuit. When this generated current reaches the value of the measured tube current a signal is generated to open the switch in the X-ray H.T. transformer circuit. If drained the generated current may be non-linear and further an exposure time indicator may be provided.

Abstract: 600,010. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd (International Standard Electric Corporation). June 27, 1944, No. 12185. [Class 40 (iv)] [Also in Group XL (c)] A gas discharge tube which tests for the presence of a particular condition is made to take account of the continuance of the condition by causing it to test repeatedly under the control of an interrupter. In an identification system, the 20-line group containing a calling line is first identified by a multi-wiper finder F, and an appropriate final selector then hunts over the level allotted to that group to identify the individual line. The test wires of each 20-line group are commoned and connected over transformers T1 to the contacts of the finder F, each wiper of which is connected over a transformer T2 to the control electrode of a cold-cathode tube L. When a calling line has been extended by first and second line finders LF1, LF2, an alternating potential is placed on the test wire from a source Q and the finder F is started by relay Ar. In due course the marking potential stepped up by transformers T1, T2 fires the tube L which is biassed from a potentiometer Pt and relay Tr energizes in the main discharge path and disconnects relay R1, which was connected up by Ar. Relay R2 energizes over the left-hand wiper provided no other finder F is standing in the same position and brings about the operation of slow-release relay Sr1 which closes a marking or indicating circuit X and a periodically interrupted circuit for relay Vr. Each time relay Vr operates it extinguishes the main gap of the tube L which therefore tests again. If the marking potential is absent, the continued operation of R1 brings about the release of Sr1. To guard against operation by spurious impulses, it may be arranged that no indication is given until the tube L has responded a second time. Specification 597,688 is referred to.

Filed: 1943-07-27
Abstract: Apparatus for drawing and forwarding thread at a speed depending on the tension therein, comprises a roller 34 having a diameter varying about its length, guides on each side thereof for directing the thread round the roller and <PICT:0569669/IV/1> <PICT:0569669/IV/2> for determining that part of the roller around which it passes and means for varying the guides against the thread tension towards the larger end of the roller so as to cause the thread to be drawn and forwarded at a speed inversely with the tension in the thread. A single end of thread from a bobbin 2 or spinning meter is passed through a treating bath 3, a drying frame 5 and a further treating bath 9, by feed rollers 14, 15, either or both of which are positively driven.  It is then fed through softening chambers 21, 17, the water or steam in chamber 21 being at about 5 lbs./sq. in. pressure above that of the steam in chamber 17 so that the pressure difference will assist the thread in moving from chambers 21 to chamber 17 through the orifice 24.  After leaving the chamber 17, the thread passes through a fixed guide 27 to a guide 46 carried by an arm 43 pivoted at 42 to a stationary arm 41. From the guide 46 the thread passes over the top of the conical roller 34 to a guide 55 carried by a rod 56 pivoted to a bracket 58.  An adjustable spring 48 biasses the guide 46 towards the larger diameter of the roller 34 while a spring 59 maintains the end of the rod 56 in contact with the arm 43.  After leaving the guide 55, the thread is led under the rollers 34 by a guide 47, attached to the guide 46, and then it is led over the roller 34 to fixed guides 29, 30 and to a ring-spinning frame 32.  In starting up, the thread is positioned toward the smaller end of the roller 34, but as the stretched thread passes through, the thread is led toward the larger end, and in normal operation, passes about a cylindrical portion of the roller at the larger end. Specification 537,962 is referred to.
