Classes 106(v) and 116 Apparatus for dispensing measured quantities of liquid or semi-solid stuff comprises inner and outer cylinders in telescopic relationship, a piston within the outer cylinder sliding freely within the bore of the inner cylinder to displace therefrom a measured quantity of substance. As shown, Fig. 1, the dispenser 10 is adapted to be attached to a wall by a bracket 11 and an inverted bottle 12 is secured to the dispenser by an encircling strap 14 and screwed clamping rod 15. The apparatus 10 comprises outer and inner cylinders 16, 17, normally held in open telescopic relationship by a spring 20. A piston 21 is adapted to engage the bore of cylinder 17 the piston head 22 being axially adjustably secured in the cylinder 16 by grub screw 23. The head 22 is provided with three holes 29 through which the substance to be dispensed passes from the bottle 12 to the cylinder 17 On upward movement of cylinder 17 the piston causes ejection of substance through the non-return valve 25 formed by a rubber cap having a slit 26. The interior of the bottle 12 is vented to the atmosphere via tube 36 which passes upwardly through the bottle and is open to the atmosphere at 37. The piston 21 is bored to accommodate a spring controlled valve 33 so that if the suction effect created by the downward movement of cylinder 17 becomes too great the valve 33 is pulled down against spring 35 thereby placing the bottle 12 in direct communication with cylinder 17. Unauthorised interference with the dispenser is prevented by a key lock 44 which is received by a pin 42 projecting from a flange of cylinder 16 and passing through a boss 43 in the wall bracket 11. This key lock together with a skirt 41 depending from the bracket 11 protects the screw 40, which secures the rod 15 and hence the bottle 12 to the dispenser, the screws 39, securing the dispenser to the wall, and the screw 23 by which vertical adjustment of the piston 21 is effected. Instead of arms 28 the cylinder 17 may be raised by a lever system carried by the apparatus.

Filed: 1972-02-08
Abstract: 1388475 Detecting flaws photo-electrically JOHN DALE Ltd 14 March 1973 [8 Feb 1972] 5922/72 Heading G1A Apparatus for detecting flaws in hollow articles comprises a source of electromagnetic radiation separated from sensing means by a shield movable to a retracted non-shielding position, and means for entering the hollow article over the source. As shown, Fig. 1, an I.R. source or incandescent lamp 18 is supported at the end of a fixed tube 16 mounted in a housing 10 the forward end of which has a head member 32 carrying twelve light sensitive switches 33 disposed round the source 18. A shielding tube 20 surrounds the source 18 and fixed tube 16 and is biased to the left by means of a tension spring 23. The forward end of the shielding tube 20 is provided with a member 30 having an annular recess 31 which receives the open end of the hollow article which may be a collapsible tube. The closed end of the article is engaged by a conical recess 57 in a nylon block 56 which is moved longitudinally by a double acting pneumatic ram 37. In operation a conveyer (not shown) presents an article to the apparatus the ram 37 is operated so that the open end of the article (the skirt of a collapsible tube) enters the recess 31 and pushes back the shielding tube 20. The article surrounds the light source 18 and any flaw in the tube is detected and a signal passed to a memory circuit for subsequent operation of an ejection mechanism. The ram is then returned to its starting position allowing the tube to be pushed out of the apparatus on to the conveyer by the spring loaded shielding tube.  The ram 37 also actuates micro-switches 47 and 48 by means of sliding shaft 45. When the end of the shaft 45 releases the operating arm of switch 48 the memory circuit is interrogated and if a flaw was detected two lifting rams (35) are operated to pivot ram 37 so that block 56 is moved clear of the end of the article. A blast of compressed air is then applied via a plenum chamber 60 and the forward end of tube 20 to remove the article from the conveyer. Further movement of ram 37 actuates switch 47 to reset the memory circuit and return the ram to its operating position. If no fault is detected the article is moved on by the conveyer which presents the next article for test.

Abstract: 1,135,041. Detecting coatings on tickets and other carriers. PLESSEY-UK Ltd. 27 Jan., 1966 [11 Feb., 1965], No. 5978/65. Heading G4T. A ticket 6 (Fig. 3) or other carrier with a magnetic or conductive coating is placed for test so that it influences the flux coupling the magnetic cores 14, 16 of a primary winding 11 (Fig. 1) and a secondary winding 13, and a winding 12 on a further core 15 coupled magnetically with the cores 14, 16 is either connected to oppose the field produced by the winding 11, as in Fig. 1, or is connected in series with the secondary 13 to oppose the voltage in this winding. The apparatus illustrated is designed to pass tickets with coatings lying in a predetermined permeability range while rejecting tickets with coatings whose permeability lies above or below this range or which are conductive. The apparatus cuts a portion from a valid ticket and imprints the remainder. The residual voltage from the secondary 13 when no ticket is present is arranged to be in the opposite sense from the voltage when a valid magnetic ticket is present. Thus if the coating on a ticket is below the acceptable permeability range (or the coating is conductive) the lower coupling provided causes a higher residual voltage. A coating with a permeability greater than the permitted range reverses the residual voltage so that in both cases the absolute value of the voltage is greater for an invalid ticket than for a valid ticket. The output from the secondary 13 (after correction by a pre-set component RV1) is amplified at 8 and rectified at 9a. The rectified voltage is compared with a rectified voltage from a further generator 3 in a comparator 9 which can be arranged to give a positive voltage for an invalid ticket and a negative voltage for a valid ticket or vice versa. The position of the ticket in the comparator is detected by two micro switches, one operated when the ticket is partly inserted and the other when the ticket is fully inserted. When the latter has been operated the signal from the comparator 9 causes the end section of a valid ticket to be cut away by a guillotine and an imprint to be made on the remaining portion of the ticket. The guillotine cannot again be operated until the microswitch indicating partial insertion of the ticket has been released and made again. The pressure of an invalid ticket causes a warning to be given. The tester may be fed by generators 1, 2, 3 on a single shaft 4 or by a transistor oscillator.
