Abstract: 836,594. Soldering. BIRFIELD TOOLS & DESIGNS Ltd., [formerly TOOLMAKERS & DESIGNS (COVENTRY) Ltd.], and LANCASTER (LONDON) Ltd., G. K. Sept. 11, 1957 [Juno 15, 1956], No. 18501/56. Class 83 (4). Apparatus for removing the soldered-on closure member from a metal container has a frame in which the container is located, heating means to be brought adjacent to or in contact with the soldered joint and means incorporated in the holding frame to lift the container from the closure member when the solder melts. A bed 5 has guides in which are slidable four blocks 6-9 each having a pin 16 passing through a slot in the bed with a roller 18 engaging a slot 11 in a cam 10 rotatable by a hand wheel 15 through a worm and a wheel 12. Slides 19-22 are mounted on the blocks and are adjustable on the blocks by screws 23-26 fixed relatively to the blocks and passing through nuts 27 on the slides. The screws each have a sprocket-wheel mounted on its outer end, these wheels being connected by chains 40, 41 to sprocket-wheels on shafts 34-37, the shafts 34, 35 having sliding pin-and-slot connection with the ends of opposed shafts 32 and the shafts 36, 37 having similar connection with the ends of shafts 33. Hand wheels 28, 29 are mounted on the screws 24, 26 to effect adjustment of the slides on the blocks. To urge the rollers 18 against the cam slots springs 45 are provided between blocks 43 in which the screws are slidable and collars on the screws. On the slides 19-22 are mounted laterally-adjustable frame members 46-49 each carrying spring- mounted electric heaters 51, the members 48, 49 additionally carrying slide members 54, 55 downwardly inclined to overhang the members 48, 49 and spring-urged forwards. In operation with the frame members adjusted by moving the slides 19-22 by turning the hand wheels 28, 29, a metal container 57, e.g. for telephone radar or electronic apparatus having a soldered-on closure 58 is located with its edge 60 on a stepped part 61 of the slide members 54, 55. The hand wheel 15 is then rotated to rotate the cam and move the blocks 6-9 and hence the members 46-49 forwards so that the switchedon heaters engage the soldered seam, lips 58 being provided on the heater casings to engage the seam 58. The members 54, 55 on the inward movements of the frame members 48, 49 move along their inclined slideways and so lift the container away from its closure member.

Title: Nonwoven web material and a method for making same
IPC: D21H13/40
Filed: 1966-04-28
Abstract: A reticulate non-woven web materialwhich may be used for many purposes, for example in making lamp shades, place mats, tea bags, or as a ply in a laminate - is formed by depositing on a wire screen which has a mesh size less than 50 and a plurality of upstanding knuckles formed by the warp strands crossing the weft strands a fibrous slurry to form a lightweight web in which there is a relatively low fibre concentration on the knuckles and a relatively high fibre concentration between the knuckles.  The slurry may contain wood, cotton, hemp, rayon, nylon, acrylic, vinyl, polyester, synthetic cellulosic, asbestos, quartz, or glass fibres, and also dispersing agents.  The wire screen preferably has a mesh of between 8 and 45 strands/inch.  The weft strands are monofils and are straight while the warp strands are preferably multifilaments strands and bend under and over the weft strands.  The weave is preferably plain and the strands may be of bronze, stainless steel, or a plastics.  Various examples of screens are given.  The paper-making apparatus used may be one in which an upwardly inclined stretch of the wire screen forms one side of the headbox or may be a Fourdrinier or cylinder machine.  In one example a slurry of hemp and bleached kraft wood pulp was fed to a headbox of the above mentioned inclined wire paper-making apparatus and a very dilute slurry of fibres of hemp, wood, and a copolymer of vinyl acetate and vinyl chloride was fed to the exit end of the headbox, and a two phase heat seal paper was formed as in specification 621823.  Tea bags were made from this paper.  In another example a web after having been dried was saturated with a latex dispersion of a copolymer of acetate and an acrylic monomer.

Title: Plugboard for use as a fixed pattern store for a pattern attachment of a circular knitting machine
IPC: D04B15/66
Filed: 1972-04-24
Abstract: 1372471 Knitting machines; pattern mechanisms MASCHINENFABRIK SPAICHINGEN GmbH 24 April 1972 [10 May 1971] 18810/72 Heading D1C [Also in Divisions G3 and G4] A programme store comprises a plug board having a plurality of sockets wherein at least one magnetic field dependent resistor is associated with each socket and the magnetic field influencing each resistor is charged by a plug inserted in the respective socket. The resistor is connected in a switching circuit and the charge in resistance causes the conductivity state of a respective transistor to change. Preferably each socket has two resistors 10a, 10b associated with it to give four separate combinations of signals on the output terminals 19a, 19b. In the construction shown in Figure 4 the resistors are in the air gap of a magnetic circuit comprising magnet 26 and yokes 27, 28. The plug has magnetic shunts 31 which when inserted divert the flux around the air gap. The plugs 301 may carry one or two shunts or can be omitted altogether to give the different codings and are shaped to only fit in one way. The conductors 13, 14, 15 are printed on insulating plate 20 and the resistors after insertion are secured by dip soldering. The store is interrogated by cyclically earthing the row conductors 13. The store is stated to be used for a pattern attachment of a multi-system circular knitting machine where the plugs represent the stitches of a pattern repeat and the rows and columns correspond to the stitch courses and wales respectively.

Title: Air circulation system
IPC: B60H1/00
Filed: 1974-04-30
Abstract: 1468706 Vehicle ventilating systems NISSAN MOTOR CO Ltd 30 April 1974 18894/74 Heading F4V In an air circulating system for a motor vehicle the rate of flow of air is varied by continuously and periodically varying the speed of the fan, Fig. 1. Also the outlet duct 6, Fig. 5, may be reciprocated backwards and forwards behind the grille 5 to vary the path of the air flow. For this purpose the duct 6 is flexible or jointed and is attached by a rod 9 to a pin 10 sliding in a slot 7 of guide 8. A lever 10 pivoted to the guide end 11 has a slot engaging the pin 10 and is connected at the other end to a crank or eccentric 17 rotated by motor 14. The fan motor 47, Fig. 1, and motor 14, Fig. 5, are each controlled by a circuit, Fig. 2, which generates a cyclically varying signal. A magnetic recording medium 25 carries a record of amplitude modulated pulses or sinusoidal signal. The head 24 reads this signal and it is amplified at 27, rectified at 29 and smoothed at 31 to give the varying amplitude signal 32. This is applied to each of a series of triggers 36 each of which operates a relay 38 through an amplifier 37. The triggers respond at successively higher voltages and the corresponding relay contacts 38 are connected in a ladder circuit with resistors 39 between earth and motor 14. As the voltage 32 rises the triggers set successively, picking the corresponding relays and shortening the chain of resistors so that a greater voltage is applied to the motor and it runs at a greater speed. As the voltage 32 decreases the operation is reversed. The outlet duct thereby reciprocates at a varying rate, changing the direction of the air flow. The volume of the air flow also changes cyclically so that people in the vehicle are subjected to recurrent stimulations. The air circulation system using a reciprocating grille, Fig. 5, forms the subject of divisional application 28624/76 (Pending).
