Title: Improvements in adjustable wrench
IPC: B25B13/46
Filed: 1919-09-03
Abstract: 137,810. Palm, V. F. L. Jan. 13, 1919, [Convention date]'. Ratchet and like wrenches; wrench-jaw faces and attachments; sliding-jaw wrenches; pivotedjaw wrenches.-An adjustable wrench is so constructed that the jaws grip a nut securely when actuated in one direction, but on a reverse movement of the wrench handle the lower jaw moves so as to slip past the corner of the nut, and the next pair of sides of the nut are gripped securely when the wrench is again reversed. The movable jaw member may be held secure by a catch when it is desired to use the device as an ordinary wrench. As shown in Figs. II and III, the wrench comprises a fixed jaw 1 integral with a plurality of guide-members 2, 3, over which slides a carrier composed of side members 4, 5, 6, 7, the members 4, 5, having bent edges 8, 9 Fig. V, which embrace the edges of the guides 2, 3, and the members 6, 7, being connected to a fixed nut 14 which is engaged by a screw 19 with a head 20 secured between ledges 23, 24 on a member 22 secured to the guides 2, 3 and connected to a wooden &c. handle 29. Between the members 6, 7 is arranged a movable jaw 33, formed as shown in Fig. VI with a rear part 36 provided with pins 40, 41, which are guided by slots 45, 46, in the carrier members 4, 5. A spring 48 tends to keep the member 36 in the position shown with the pins 40, 41, in the slots 45, 46, and a spring 52, which is arranged on a projection 53 of the screw 19 and is secured to a lug 39 in a recess 38 on the underside of the jaw 33, tends to keep the jaw in its normal position shown in Fig. II. By engaging a catch 64 formed with split sides and with an operating knob 67 under a hook 37 formed on the part 36, the jaw 33 is held rigidly in its carrier, and the device can be used as an ordinary wrench. If, however, the catch 64 is disengaged and the wrench is operated in the direction of the arrow C, Fig. II, the nut A will be rotated and the jaw 33 is rigid. On the reverse movement, however, the jaw 33 moves to the position shown in Fig. III, the pins 40, 41 assuming the positions shown, and the abutment 50 on the jaw moves from off its supporting ledge 51, Figs. II and V. The jaw thus moves past the corners of the nut, and on again reversing the movement, the jaw 33 assumes its original position and moves the nut. The spring 52 is protected by a spring-controlled flap 58 and an apron 59 attached to the jaw 33. In a modification, Fig. VIII, the jaw 33 is formed with two supporting surfaces 51<a>, 51b, with which correspondingly shaped members co-operate, and a leaf spring 48<a> replaces the coiled spring 48. In this modification, the jaw moves so as to remain substantially parallel to its original position. In a further modification, Fig. XI, the jaw 33 is guided in its swinging movements by one pin 40a and one slot 45a, and by a link 74 arranged in a recess.

Abstract: 500,880. Alkyl chlorides ; purifying olefines; catalysts. STRANGE, E. H., and KANE, T. Aug. 16, 1937, No. 22425. [Class 2 (iii)] [Also in Group III] Alkyl chlorides are made by reacting olefines with hydrochloric acid in the presence of a catalyst referred to as " prepared bauxite " which is made by wholly or partially dehydrating a bauxite containing less than about 5 per cent of iron and less than about 1À5 per cent of titanium, the heat treatment being at 200-600‹ C. for 2 to 48 hours. The olefines may be first freed from diolefines by adding about 1 per cent of hydrochloric acid and passing over a polymerizing catalyst which may be prepared bauxite or other bauxite. The olefines are then mixed with about the equivalent quantity of hydrochloric acid and passed over the prepared bauxite. At 80-110‹ C. propylene and higher olefines are converted into alkyl chlorides. After separation of these chlorides, the remaining ethylene, to which more hydrochloric. acid is added if necessary, is passed over the prepared bauxite at 150-300‹ C. for the production of ethyl chloride. When the catalyst requires regeneration, it may be treated with a solvent for tars &c. or may be heated, preferably not above 600‹ C. Specifications 353,032 and 414,766 are referred to.

Patent GB-893188-A (GB)
Title: Furfuryl alcohol resins
IPC: C09D163/00
Filed: 1958-07-15
Abstract: Furfuryl alcohol resins (i.e. condensation and polymerization products derived from furfuryl alcohol, and mixed condensation products of furfuryl alcohol and furfural) are modified to render them more suitable for use in lacquers by blending them with certain chain-like polymers containing free OH groups in the chain and heating the blend.  The chain-like polymers containing free OH groups in the chain are chosen from (1) vinyl chloride/vinyl acetate copolymers which have been modified by the introduction of free OH groups into the chain, (2) epoxy resins, (3) alkyd resins and (4) polyvinyl ethers which contain OH groups in the chain. Preferably the chain-like polymer is dissolved in a lacquer solvent before blending with the furfuryl alcohol resin, the solvent being removed by boiling at the beginning of the heating step.  Lacquer solvents mentioned are furfural, ketones, alcohols and esters.  But when furfural is employed as solvent the heating step may be carried out under reflux and the greater part of the furfural driven off under vacuum at the end of the heating step. About 10% of furfural (based on the modified resin) is left to form an ingredient of the lacquer.  In the examples, a furfuryl alcohol resin (formed by the condensation of furfuryl alcohol in the presence of an acid catalyst according to the process of Specification 850,413) is heated with (i) a solution of polyvinyl butyral in a mixture of ethanol and butanol or (ii) a solution of a partially saponified vinyl chloride/vinyl acetate copolymer in furfural.  Lacquers are produced from the product of (i) by dissolving in a mixture of ethyl acetate, butanol and ethanol and adding a hardener consisting of a 3% solution of sulphuric acid in ethyl acetate, and from the product of (ii) by dissolving in a mixture of ethyl acetate, methyl isobutyl ketone and methyl ethyl ketone.

Abstract: 1371821 Moulding tyres GOODYEAR TIRE & RUBBER CO 15 May 1972 [1 June 1971 14 March 1972] 22746/72 Heading B5A  A tyre mould comprises an upper part 18 movable coaxially relative a lower part 14, tread mould segments 22 movable radially and in axially fixed relation to the part 14 which has cam means for moving the segments radially outwardly, and a ring 93 associated with the part 18 for moving the segments radially inwardly when that part is lowered. The part 14 is located on a platen 12, and the lower surface of each segment carries a T-block 50 which slides in a T-slot 52 in the platen. A cam follower 62 is attached to each block and engages a cam ramp 69, Fig. 3, of a cam ring 32 which is rotated about the mould axis by a fluid operated cylinder 76. Rotation of the ring in one direction forces the segments outwardly whereas rotation in the opposite direction allows the segments to be moved inwardly by the ring 93. The ring forms part of a bolster 90 from which depends a platen 16 attached to the part 18, relative movement between the parts 90 and 18 being provided by a number of spring sets 130 and bolts 140. The cam means of Figs. 5-6 includes a cam ring 160 rotated about the lower platen by a cam plate 164 integral with a part-cylindrical plate 170 having a cam slot 172. A stud 174 on the ring 93<SP>1</SP> engages the slot when the ring descends, causing rotation of the plate 164 and permitting a spring-loaded pawl 180 on the plate to pass into a next adjacent notch 188 of the ring 160. Rotation of the latter is prevented by each cam follower 62 engaging a face 190 of a notch. Upward movement of the bolster and ring 93<SP>1</SP> effects clockwise movement of the cam ring whereby the tread segments are moved outwardly. Subsequent downward bolster movement causes inward movement of the segments. In the embodiment of Fig. 8, not shown, the cam ring (200) and cam drive plate (202) are integral, the latter having an upwardly extending slotted plate engaged by a stud (208) on the bolster ring (93<SP>11</SP>); upward bolster movement effects outward radial movement of the tread segments. In an alternative construction, Fig. 11, the slide blocks 257 have portions 263 of limited radial width to permit easier withdrawal of the segments from their T-slots. The upper platen 237 is vertically driven by an hydraulic cylinder and includes a bearer ring 277, preferably of a metal dissimilar from that of the segments 243 and of the closing ring 279. Relative movement of the upper platen relative to the bolster 271 is limited by bolts 291.
