Title: Improvements in envelope making machines
IPC: B31B23/00
Filed: 1932-05-17
Abstract: 394,474. Cutting paper webs. NEWELL, E., Port Credit, Ontario, Canada. May 17, 1932, No. 13974. [Class 31 (i).] In an envelope-making machine in which a paper web is passed between rotatable members having at both ends overlapping faces each formed with a segmental flange, the said members are so arranged and driven that the segmental flange of each face registers with the unflanged portion of the opposing end face so that side recesses with smooth edges are sheared out from the web so as to provide envelope blank flap portions at the longitudinal edges of the web. A web of paper is led from a reel 1 between fountains 5, 6, colouring fluid being applied to the web by rolls 7 .. 10. The web then passes to embossing rollers 13, 14 and printing rollers 15, 16, 17. The side edges of the web are next cut by cutting rollers 19, 20, having cutting flanges 21, 22, strips being cut off at 2x to leave intervening side flaps 2‹. Creasing means, consisting of discs 23 engaging ' in grooves of a drum 25 now slightly turn up the side flaps 2o, a pressure bar 29 holding the main portion of the web flat. Arched plates 30 bevelled on their inner under surfaces and fixed to a bar 31, now engage the partly turned-up side flaps and lay them over on to the bevelled edges of a bar 32, the flaps being ironed down by rollers 33. The flaps are now gummed by rollers 60. The web now reaches the folding rollers 34, 53 and cutting roller 36. The folding roller 34 comprises creasing grooves 38 :. 41 at the inner ends of which are mounted rocking gripper shafts 42 .. 45. Attached to a fixed support is a member carrying cam surfaces, upon which a tail member of each shaft 42 .. 45 bears, due to spring pressure, to hold the appropriate shaft in the non-gripping position. As the web is led onwardly, the cutter 35 cuts it transversely, the portion of the web on each side of the cut being positively separated by means of a bar 54, countersunk in the roller 34, being raised by a cam 58 operating on spring- urged bars 56, pivoted at 55, which through pin-and-slot connections 56<x> move the arms which operate the bar 54. The leading edge of the cut blank is thus raised and moves along a table 53<x>; the blade 36<x> now tucking the fold x into the creasing groove 38 where the cam-operated bar 42 grips it. On further movement of the rollers 34, 53 the blank, gripped at 38, advances until the blade 52 enters the creasing groove 39 to form the crease y, the leading part of the blank having been folded backwardly in passing the edge of the table 53<x>, on to the inturned gummed flaps 2‹. A gummer on roller 53 applies gum to the flap z of the envelope. The creasing grooves with the corresponding shafts 42, 43 and 44, 45 operate alternately.

Patent GB-735208-A (GB)
Title: Improvements relating to the treatment of crimped fibres of acrylonitrile polymerization products
IPC: D06M13/127
Filed: 1951-06-12
Abstract: The crimp of a longitudinally crimped gelled fibre of an acrylonitrile polymerization product, containing at least 35 per cent by weight of combined acrylonitrile, is stabilized by contacting the longitudinally crimped fibre with a fluid medium comprising water or steam at a temperature above 100 DEG  C. but not exceeding 150 DEG C.  The treatment may be carried out under acid conditions and in such case the colour and colour stability of the fibre are also improved.  Longitudinally crimped fibres are those which have been crimped by subjecting them to longitudinal compression.  The fibres may be obtained by cutting continuous filaments which have been produced by extruding a solution of an acrylonitrile polymerization product into a cold, liquid coagulant comprising water at a temperature not exceeding +10 DEG  C.  The water-swollen aquagel filaments may be stretched in presence of water at 70-110 DEG  C. The acrylonitrile polymerization product may be a copolymer of acrylonitrile with a vinyl ester, vinyl or vinylidene chloride or fluoride, allyl alcohol, an allyl ester or acrylic or methacrylic acid or an ester or amide thereof, or it may be a copolymer of acrylonitrile with isobutylene or with an ester of an alpha or beta unsaturated polycarboxylic acid such as maleic, fumaric or citraconic acid.  The molecular weight of the polymer may be 15,000-300,000.  In an example, a solution of a copolymer of 95 per cent acrylonitrile and 5 per cent methyl acrylate in aqueous calcium thiocyanate is extruded into cold water and the filaments obtained are stretched at 100 DEG  C. while immersed in water.  The filaments are then submerged in cold water and stored in wet state until required for stapling and crimping. A swatch of fibres obtained from these filaments is crimped by compressing it longitudinally, while in gel state, in a cylindrical brass tube, 0.25 inch in diameter.  The crimped swatch is removed and placed in an autocalve in which it is steamed for 30 minutes at 50 lbs. per sq. inch gauge pressure.  It is then removed and dried in warm air.  In another example, the swatch of fibres is soaked in dilute hydrochloric acid solution prior to the crimping and the solution is adjusted so that a pH of about 2.6 prevails during the crimping and the subsequent crimp stabilization, which is performed in the presence of steam under pressure.  In another example, the acidified and crimped swatch of fibres is immersed in dilute hydrochloric acid of pH 2.6 and the containing vessel is placed in an autoclave in which it is steamed for 30 minutes at a gauge pressure of 50 lbs. per sq. p  inch. Specifications 594,999, 672,775 and 735,183 are referred to.
Patent GB-971921-A (GB)
Title: Process and apparatus for producing thermoplastic articles
IPC: B29C48/10
Filed: 1962-04-12
Abstract: 971,921. Moulding thermoplastic articles. K. MAGERLE. April 12, 1962 [April 19, 1961; June 15, 1961], No. 14165/62. Heading B5A. A thermoplastic article is made by injecting hot plastic from a feed plunger into an open mould, closing the mould and pressing by relative movement of the mould parts, which may be cooled. In the embodiment illustrated in Fig. 1, the neck of a tube 25 is formed in a mould consisting of a core 3, 2 and die 19, 17. The lower half shows a section of plastic tube 6 projecting beyond the core shoulder, while plastic 8 is sprayed through apertures 4 in a feed plunger 1 (by movement of a piston 10) on to the inner face of tube 6. The upper half shows the end of the pressing process, when the carriage 13 has moved forward carrying the annular die 19 and the two movable die jaws 17. When the die jaw closure portions 29 pass apertures 4 they scrape off the surplus plastic, finally jaws 17 close together, forming the plastic and welding it to the tube. In the embodiment illustrated in Fig. 2 (not shown), the arrangement is similar to Fig. 1, but the die jaws 42 have separate closure slides 43 which on coming together, with jaws 42 closed, form, with a die 37 and core 38, a completely closed mould before the hot plastic is actually pressed. The modification in Fig. 4 (not shown) is used to form a tube neck with an aperture. Fig. 5 shows a similar arrangement used to make a tapped cap 101. Here the cap is formed entirely from injected hot plastic, sprayed from two concentric sets of apertures 107 in a feed plunger 102 on to a core 108. A sleeve 119 advances, cutting off the flow of plastic, then carriage 110, with a die 109 and die jaws 125 advances; the mould is closed when the die 109 contacts sleeve 128 on core 108, jaws 125 then being closed. Further advance of carriage 110 effects the pressing of the plastic 101 into the shape in the upper half of Fig 5, while sleeve 128 is moved along core 108 against springs 130. The cap 101 may be shaped further by a series of pressings in progressively smaller dies. Fig. 7 (not shown) illustrates such an arrangement, a series of cores 146 being arranged on a turntable and coming in turn under a feed plunger 140 and die 150, subsequent pressings being effected by dies 151, 152. Figs. 9, 10 (not shown) illustrate equipment identical to Fig. 1, except that mould closure is effected when plates 176 engage around the core 167. Figs. 11-16 (not shown) illustrate progressive formation of a screw-thread by successive die jaws of different shape and orientation. Figs. 17, 18 illustrate the pressing of a cap 224 in two stages. A cylindrical blank 203 is formed in a die 201, mould closure being effected by a sleeve 204 in groove 205 engaging with a conical surface 222, further advance of die 201 doing the pressing. Plunger 212 carrying blank 203 is then moved to engage with die 223, and the second pressing is performed.

Abstract: 1,176,313. Cryotron selection matrix. SIEMENS A.G. 25 March, 1968 [23 March, 1967], No. 14278/68. Heading G4C. [Also in Division H3] Selecting matrix, connecting control lines in a superconductive store to a pulse source, has a cryotron having three equal ranking control conductors provided at each intersection of the matrix, with the first control conductors of all the cryotrons in each row being connected in a series chain, the second control conductors of all the cryotrons in each column being connected in a series chain and the third control conductors of all the cryotrons in the matrix being connected in a series chain, and has the gates of the cryotrons connected together to form one or more series chains of gates, each gate being shunted by a wire which is also a control wire of the superconductive store. The gates can be connected as shown in Figs. 1a or 3, the extra decoupling cryotrons r serving to reduce the time constant of the circuit. In the rest state of the circuit the cryotrons are in their superconductive state and all shunt wires U are short circuited. The third control wire carries a current I t  less than the critical current Ic for instance 2/3 Ic. The row I r  and column Ic currents are such that I t  + I r  or It + Ic are less than the critical current while It + I r  + Ic is greater than the critical current to cause the selected cryotron to change to its normally conductive state and the control current Ia to pass along the corresponding shunt wire to the store.

Title: Improvements in or relating to agricultural machines for planting crops
IPC: A01C11/02
Filed: 1947-05-30
Abstract: 627,358. Transplanting-machines. TAPP, E. T. J. May 30, 1947, No. 14450. [Class 6(i)] A transplanting-machine comprises a belt 24 encircling pulleys 23, 25, 26, one of which is disposed adjacent to the ground, the belt being provided with tongs 35, which open to receive plants as the belt flexes over an upper pulley 25 and open again to release the plants as the belt flexes over the lower pulley 23. Operators on seats 13 place the plants in cups on an endless belt 14 running transversely across the machine. The cups are arranged in pairs 18, 19 with a space 20 between them. The bent ends 36 of the tongs 35 enter each of the spaces 20 as the belt 14 passes over one of its supporting pulleys 15 to grip a plant and carry it downwardly. To ensure synchronism between the motions of the tongs 35 and the cups 18, 19, the planting belt 24 carries pins 37 which engage similar pins 21 on the feeding belt 14 and drive the latter in step-by-step relation. Alternatively, a Maltese-cross mechanism may be employed. To prevent the tongs being opened in passing over the intermediate pulley 26, the latter is flanked by discs 38 against which the pins 37 lie in passing around the pulley, the intervening portions of the belt 24 being straight. Alternatively, the pulley 26 may be polygonal. The tongs open as the belt flexes around the pulley 23 and the seedlings fall into a furrow formed by an elongated shoe 30, consolidation being effected by a pair of inclined presser wheels 32. A single land wheel 12 drives the belt 24. Specification 627,325 is referred to.

Title: Improvements relating to apparatus for decoding digital code signals
Inventor: JONES IAN CLIFFORD
IPC: G09C1/10
Filed: 1958-05-07
Abstract: 931,762. Electric selective signalling. ELECTRIC & MUSICAL INDUSTRIES Ltd. Aug. 7, 1959 [May 7, 1958], No. 14612/58. Class 40 (1). Apparatus for decoding electric digital representations of a continuously varying displacement, comprises means for producing electric signals from a moving member bearing a code pattern and means for decoding the signals comprising electronic valves arranged to operate as output switches. The cyclic permutation code used, Fig. 1, may be represented on a rotating disc or sliding member sensed by photo-electric or mechanical means. Applications to automatic weighing machines and digital voltmeters are mentioned. Fig. 2 shows the decoding means for one decade (tens), terminals A, B, C and D receiving positive signals corresponding with the blackened squares in Fig. 1. Inter-. pretation of each code combination in a decade is dependent on whether the digit in the next higher decade is " odd " or " even " (cf. patterns for " 5 " and " 14 " in the " units," Fig. 1). A terminal 4 receives a positive potential when an " odd " number is decoded in the next higher decade; it corresponds with an output terminal 5 which supplies a similar potential to the next lower decade (if any) when an "odd" number is decoded in the decade shown. Thus, positive signals at terminals B and C, representing " 40 " when the hundreds value is " even," cause valves V2A and V3A to conduct while, in the absence of a signal at A, valve V1B conducts. Also, since no positive voltage is received at terminal 4, a valve V6B remains non- conductive and current passes through V6A from valve V4B. Connections run from the anodes of V1A, V1B, V2A ... &c. to diodes MR1 ... MR36 grouped to form coincidence gates, and in this example the potential of the grid of V11 only is raised to provide a positive potential at an output terminal 4, representing " 40." Transistors may be used instead of thermionic valves.

A cylindrical test piece 1 has a part b, Fig. 1, which is gripped by a tensioning member 6 in Fig. 3, and its part a is closely surrounded by a truncated cone or collar 2 into which it is pressed by a force F, Fig. 2, and welded as at 4 in a heat controlled welding device 3. As a consequence of a difference in thermal conductivity the test piece increases in length more than the collar 2 so that on later cooling a residual interval axial tensile stress #int appears in part a. The thermal treatment given to the test piece varies of course according to the temperature of pre-heating the collar 2 and the hydrogen content of the welding electrodes. The lower the pre-heat temperature and the higher the hydrogen content the weaker the welded joint at the heat affected zone (HAZ), see Fig. 4. The cooled test piece with its collar 2 welded thereto Fig. 3, is tensioned by being pulled down by the screw-threaded tensioning member 6 against a heavy supported block 5 with an external force #ext greater than the internal tension #int. The residual tensile stress in the test piece may be varied.
