Patent GB-912059-A (GB)
Title: Improvements in or relating to riveting devices
Inventor: BERNSTIEL ERWIN
IPC: B21J15/02
Filed: 1959-09-21
Abstract: 912,059. Stapling-machines. STEELS & BUSKS Ltd. Sept. 15, 1960 [Sept. 21, 1959], No. 32051/59. Class 89 (3). [Also in Groups XXV and XXX] In a machine for securing together two layers 46, Fig. 4, e.g. of cardboard or fibreboard, a rivet 45 is driven through (or through holes in) the layers by a plunger 30 so that limbs of the rivet are splayed out and received in a cap 14 resting on a fixed adjustable anvil 43; and when the plunger is raised, a sprung sleeve 40 around the anvil is permitted to rise and carry with it the end of a shoot 23 (containing a line of caps 14) above the anvil 43 so that another cap slides into position on the anvil ready to receive the next rivet. The rivets are fed by a shoot 36, Fig. 3, to a split holder 31, each half of which is suspended by one of a pair of spring blades 32 from a spring- loaded support 33 movable in a fixed guide 34 of the riveting plunger 30. The downward stroke of the plunger pulls down the members 31, 32, 33 until the lowermost position of the support 33 is reached, when the plunger continues down to spread the parts of the holder 31 to release its contained rivet to penetrate the layers to be secured. The cap-shoot 23 is of channel-form and pivoted, Fig. 1 (not shown), to a feed channel which itself is in two parts pivoted together. The pivots permit the shoot, at its delivery end, to move with the anvil sleeve 40. The feed channel extends, through one end, into a horizontal drum which is a cap magazine and contains a rotor with angle irons parallel to the drum axis and moving over the inner cylindrical surface of the drum to scoop up the caps and pour them over and into the feed channel. The width of the channel is smaller than the diameter of the caps so that they are held up on edge in the channel and roll down it towards the shoot 23. To reject caps which would be fed to the anvil upside down, there is a gap in one side wall 13, Fig. 2, of the feed channel from the drum and at this gap the bottom of the channel, formed by the other wall 12, is narrowed by chamfering, Fig. 2. The caps are of such form that those 14<1>, displaying the opening toward the gap, roll along the narrowed bottom to the shoot 23, but the others 14<11> fall off for rejection.

Title: Improvements in or connected with cash-registers and like sales recording machines
IPC: G06C27/00
Filed: 1937-11-25
Abstract: 499,534. Cash registers ; photographic copying cameras. BRENNINKMEYER, A., BRENNINKMEYER, E., BRENNINKMEYER, F., BRENNINKMEYER, F., BRENNINKMEYER, H., BRENNINKMEYER, J., and BRENNINKMEYER, R., (trading as BRENNINKMEYER, C. & A.). Nov. 25, 1937, No. 32523. Convention date, Oct. 28. [Class 106 (i)] [Also in Group XX] Sales are recorded by inserting a bill, sales tag, or like slip into a machine which, upon release, causes the slip to be impressed with serial number and receipt indications ; these indications together with the data originally marked on the slip being then photographed on to a film strip having a stepwise feed mechanism. A tag, Fig. 7, attached to the article to be sold, is divided into a receipt area a and a stub area b, each marked with the price of the article and with some or all of the following additional data : stock number, purchase price, packing-table number, clerk's number, date of receipt of goods, manufacturer's number, &c. After the article has been sold, the tag is detached and inserted into a slot 7, Fig. 1, and the machine released by depression of a push-button 10. The tag is thereupon impressed in both areas with the word " Paid," a serial number, and, if desired, a firm's mark, and is then drawn into the machine. A photographic record of the data on the stub area or the whole tag is now made on a strip film, the stub is severed and stored in the machine, and the receipt is ejected through a shoot 8. Upon the insertion of the tag into the slot 7, Fig. 2, it is positioned on the upper surface of a slide 21, where it is held by a spring arm mounted on the slide. A driving motor 11, energized upon the depression of the push-button 10 or the insertion of the tag, serves to advance the strip film in a camera 14, causes the tag to be impressed with the data previously mentioned, and, through gearing including a rack 20, draws the slide and tag into the machine. As the slide reaches the position shown, a bar 34 clamps the tag to the frame of the machine and the rack drive is disabled to permit a spring to return the slide to home position. With the aid of a lamp 39, the film is exposed and receives a record of the data on the stub area of the tag. Simultaneously, or immediately thereafter, a knife 41 is depressed to sever the stub, which falls on to a transparent shoot 44 leading to a storage compartment 45. The blade of the knife is irregular to form a characteristic line of cleavage between the stub and receipt. A receipt ejecting bar 29, shifted to the right by the movement of the slide is held by a detent 31 against the action of a spring 30. At the conclusion of the operation, the detent is disabled and the ejector thrusts the receipt to the left, a spring 47 serving to guide it into the shoot 8 whereby it is delivered to the exterior of the machine. Constant matter, such as the clerk's signature may be photographed at each exposure.

Title: Improvements in graphical recording systems
IPC: B41J2/05
Filed: 1963-08-20
Abstract: In a graphical recording system (see Division B6) ink having a melting point above the ambient temperature is used.  The ink comprises a major portion of heat stable wax having substantially identical melting and softening points above the ambient temperature and a colour imparting concentration of a wax soluble organic dye of between 0.1 and 1.0% by weight of ink.  The wax may be a selected halogenated hydrocarbon synthetic wax of a chlorinated naphthalene type such as a mixture of trichloronaphthalenes and tetrachloronaphthalenes. Other waxes such as paraffin, and microcrystalline mixed with certain vegetable waxes may be used. Suitable dyes are those that include at least one phosphotungstic acid-modified triphenyl methane-type dyestuff.  The dyestuff may also comprise other selected dyes of the modified anthraquinone type, and modified phthalocyanine type. The ink may be prepared by heating particulate wax and dye together in a heating zone to above the melting point of the wax and fluidizing the wax.  The liquified solution can then be filtered or strained, as by passing it through a suitable bronze filter so as to remove small undissolved particles therefrom before allowing it to cool to solid form.

Abstract: 651,959. Uniting by fusion. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Dec. 21, 1948, No. 32974. Convention date, Dec. 30, 1947. [Class 83 (iv)] A contact mechanism for supplying current to an arc welding electrode 3 fed through it comprises guide members 16 for supporting the electrode and one or more thin contact strips 8 of substantially uniform cross-section adjustably held in electrically conductive two-part clamps 22, 23 which are of greater mass, rigidity and heat radiating capacity than the strips ; the clamps are movable relative to their supports and towards the electrode by biassing members 27 movable into and out of engagement with them. The electrode 3 is automatically fed through a grinding mechanism as described in Specification 651,922, to remove a narrow slot from the flux coating of the electrode, and thence through elongated slots in plates 5, 6 forming, together with a guide plate 7, the framework of the contact mechanism. The upper plate 5 is insulated from the grinder housing and the lower plate 6 carries spaced heat-radiating baffle plates 13. Grooved guide shoes 16 are pivotally supported by arms 17 of blocks 18 adjustable to and from the electrode on tongue and groove slides and engage one side of the electrode ; on the other side, the contact strips 8 are each clamped between members 22, 23, the member 22 having a tongue and groove connection with the guide plate. The contact strips are preferably of copper containing about 1 per cent lead and ¢ per cent selenium to provide self-lubricating properties and have each a central slot 25 permitting them to be adjusted in the clamps and reversed end for end when one end becomes worn to the full extent of the adjustment. Springs 27 engaging each clamp 22 are mounted on a square shaft 28 and a handle 32 on the shaft has a turned-down latch portion engaging a hole in the plate 6 to hold the springs in operative position but may be sprung upwards to release the latch and then rotated to free the contact clamps. If desired, the shaft may be removed by unbolting a plate 30 forming the upper bearing of the shaft and lifting the shaft from its lower bearing in the plate 6, a corner of the plate 5 being cut away to allow this. Welding current is supplied to the contact strips through a bus-bar 35, the guide plate 7, cables 34 and the clamps themselves. By individual adjustment of the guide shoes 16 and of the projection of the strips, a coiled electrode which still retains some of its curvature may be accommodated. Specifications 408,148 and 533,529 also are referred to.

Abstract: 648,228. Variable condensers. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 24, 1948, Nos. 33214/48 and 15457/49. [Class 37] A variable condenser comprises a pair of concentric electrodes 3 and 10 axially relatively adjustable and an intervening sleeve of dielectric 1 having an annular space for the reception of one of the electrodes, viz. 10. The sleeve 1 of dielectric has at one end a closed re-entrant cup 2 and at the other is closed by a metal bush 7 into which screws a spindle 9 having at one end a cup-like part 10 which is free to pass into the annulus formed between the sleeve 1 and re-entrant part 2 of the dielectric. Around the exterior part of the sleeve 1 adjacent the re-entrant part 2 is a metal cylinder 3, a flange 4 on which is soldered to a flange 6 on a cup 5 disposed in the re-entrant part 2. Rotation of the spindle 9 varies the capacity, a spring 13 in a groove 12 in the bush 7 preventing inadvertent movement of the spindle. In one modification the electrode 3 is split longitudinally to form a number of separate part cylindrical electrodes, in which case the electrode 10 may be in the form of a part cylinder, the capacity of each condenser varying from a minimum through a maximum to a minimum for each rotation of the spindle 9. Alternatively the electrode 10 may be split into a plurality of relatively fixed electrodes, and the electrode 3 formed asymmetrically with respect to the axis of the other electrodes;
