Title: Improvements in or relating to straight bar knitting machines
Inventor: BENTLEY WILLIAM
IPC: D04B11/00
Filed: 1963-02-28
Abstract: In a knitting machine, a row of individually slidable instruments, e.g. beard presser, elements or loop transfer points, is controlled by a row of corresponding electro-mechanical devices which when energized or de-energized govern displacements of the instruments and means for energizing and de-energizing the electromagnetic devices selectively.  As shown, sliders 1 with butts 1a, 1b, which operate as disclosed in Specification 933,072 to press or leave unpressed needle beards primarily for tuck patterning, are operated by droppers 2 slidable in a support 3 with a locating stop 3a for the butts 1b of sliders 1.  Each dropper 2 has butts 2a and 2c and an edge 2d engaging a shaft 5 which carries a mounting for leaf springs 4 engaging slots 3c in support 3 and for a common lifting bar 7 under the droppers. Solenoids 8 with core parts 8a are associated with top butts 2a and are selected by a programming device, e.g. of the punched card control kind.  When a dropper 2 is held raised by a part 8a, its butt 2c rides over the associated slider whereas the remaining droppers 2 lowered by the leaf springs 4 engage the rear butts 1a of the associated sliders.  Shaft 5 is advanced, e.g. as described in Specification 933,072, and the lowered droppers advance their associated sliders to press the associated needles.  Mounting (6) is then raised e.g. as described in Specification 1,057,111 so that bar 7 raises the lowered droppers until the bottom butts 2c are clear of slider butts 1a and top butts 2a are substantially opposite parts 8a.  Shaft 5 retracts carrying droppers 2 with it so that sliders 1 are retracted by the part 3a of support 3.  Top butts 2a of droppers 2 which have been held raised by parts 8a now return parts 2 to inoperative position.  The lifting bar then raises droppers 2 to an upper level with top butts 2c clear of solenoid parts 8a and ready to repeat the cycle of operations with a fresh selection of solenoids operated.  The arrangement is used in a normal straight-bar knitting machine, Figs. 4, 5, 5a (not shown) and the sliders have edges (26) for pressing the needle beards (11) and are mounted on sinker bar (22) between sinkers (21).  Shaft (5) is mounted to be operated through a linkage by a cam on the main shaft (9).  The solenoids 8 are clamped between bars (39), (40) Fig. 6 (not shown) and the cores are slidably guided in a guide bar (43).  The transfer points may be operated similarly.

Title: Improvements relating to lubricants and other hydrocarbon products
IPC: C10L1/14
Filed: 1935-03-15
Abstract: Hydrocarbon oils and greases such as gasolene, kerosene, naphtha, and lubricants, are thickened by an oxygen-free linear polymer of acetylene or an acetylenic hydrocarbon or of a halogen derivative thereof.  Acetylenic compounds specified are divinyl acetylene, diacetylene or its lower polymers, chlorprene, and alkyl or aryl derivatives of acetylene, e.g. propine, butine, phenyl - acetylene. The polymers are preferably stabilized by hydrogenation, destructive hydrogenation, halogenation, alkylation, depolymerization, condensation with other organic compounds, or addition of sulphur or hydrogen halide or other inhibitor of polymerization.  The polymerization may be effected in the lubricating oil or in a solvent; polymers of m.w. 1100--8000 are suitable, a proportion of 0,2--40 per cent being used.  The polymers may be broken down by milling, forcing a solution through a fine orifice or by heating; halogen polymers may be treated with alkali to remove part or all the halogen. There may be added to the thickened lubricants hydrogenated rubber, polymerized isobutylene or like poly-olefine, oxidation inhibitors, e.g. naphthols and thionaphthols, polymerization-inhibitors, e.g. sulphur or soluble sulphur compounds, load-carrying lead or sulphur compounds, oiliness improvers, e.g. fatty acids, carbon preventers, and sludge-dispersing agents.  In examples: (1) divinyl acetylene dissolved in xylene is refluxed in presence of air or butylamine as catalyst for 2--5 hours at 80--90 DEG  C. or at 10 to minus 50 DEG  C. in presence of boron fluoride; the product preferably freed from unpolymerized divinyl acetylene by distillation, is hydrogenated at 15--25 DEG  C. in presence of palladium, or at 30--90 DEG  C. in presence of a copper chromite or an activated nickel catalyst; 5 per cent is added to a lubricating oil; (2) chlorprene, obtained by reacting vinyl acetylene with hydrogen chloride, is polymerized by heating in presence of air or other catalyst; the polymer may be added directly to lubricants, but is preferably first condensed with naphthalene or benzene in presence of boron fluoride, aluminium chloride, acetic acid solution of sulphuric acid, or other catalyst, or is alkylated, reacted with sodium polysulphide, or is condensed by the Wurtz process.

Title: Improvements in or relating to plasticized synthetic resin compositions
IPC: C08K5/03
Filed: 1944-05-01
Abstract: A rubber-like composition comprises a resin containing from 70 to 100 per cent vinyl chloride, a plasticizer other than di-isobutyl adipate, and a plasticizer sealant consisting of either a chlorinated aliphatic paraffin having more than fifteen carbon atoms and from 20 to 68 per cent chlorine, or a chlorinated aryl hydrocarbon having two or more benzene rings each united by two common carbon atoms and containing 26 to 63 per cent chlorine, the weight of plasticizer being greater than that of the sealant, but insufficient alone to plasticize the resin to the same extent as the combination of plasticizer and sealant.  A vinyl chloride-vinyl acetate resin and chlorinated naphthalene and chlorinated anthracene are specified.  As plasticizers ethoxy-ethyl adipate, dibutyl sebacate, or dibutyl phthalate may be used.  Paraffin wax and castor oil may be added. Dipping solutions may be made by adding acetone and cyclohexanone. Dyes, fillers and stabilizers may be added.  Gloves and fountain pen vacs may be so made.  Specifications 573,841, 633,940 and 633,941 are referred to.
Patent GB-256523-A (GB)
Title: Means for regulating the fuel supply to furnaces and the like
IPC: F23N5/20
Filed: 1926-03-25
Abstract: 256,523. Reineke, J. H., and Unipressure, Ltd. March 25, 1926. Gascous-fuel furnaces.-The gaseous fuel supplied to a furnace is maintained at constant "calorific capacity," i.e. the same amount of calories are supplied per unit of time, by a pressure regulator acting in conjunction with a regulator automatically operated in dependence on the heat imparted to a calorimeter by a burner fed by a branch pipe from the main gas supply. The pressure regulator may adjust a valve in the main gas supply or in a pipe supplying richer gas to mix with a poor gas. The throttle valve 5 in the main gas pipe 1 having branches 2, 3, 4 leading to the furnaces &c. is controlled by a device A of the kind described in Specification 144,304, [Class 135, Valves &c.], comprising differential gearing 6 actuated by two motors 7, 8 rotating in opposite directions at speeds controlled by the pressure regulator B. A calorimeter C supplied with water by inlet and outlet pipes 11, 12 and heated by a burner 9 supplied by a branch pipe 10 from the pipe 1 contains a thermo-junction connected to a galvanometer 15 the arm 14 of which engages with one or other of two contacts 16, 17 according as the temperature difference in the pipes 11, 12 is above or below a predetermined value. One of two relays 20, 27 is thus energized controlling the direction of rotation of a motor 13 driving through gear-wheels 42, 41 a screwed rod 40 of the pressure regulator B. A platform 38 sliding on guide rods 43, 44 engages by a nut 39 with the threaded rod 40 so that this platform is raised or lowered according to the direction of rotation of the motor 13. Pivoted to the platform 38 is a lever 33 carrying contacts 34, 35 and connected by a rod 32 with a float 30 in a pipe 29 the lower open end of which is immersed in liquid in a vessel 28 communicating by a pipe 31 with the gas supply pipe 1. Contacts 36, 37 fixed to the platform 38 are adaptad to engage with the contacts 34, 35 as the arm 33 is inclined in opposite directions due to the raising or lowering of the platform 38. The making of one of these contacts causes a resistance to be short-circuited in the circuits of one of the motors 7 or 8 thus increasing the speed of this motor and causing the differential gear 6 to open or close the valve 5 according as the platform 38 is raised or lowered i.e. according as the calorific value of the fuel is below or above the predetermined valve.

Title: Improvements relating to face mill cutters
IPC: B23F21/24
Filed: 1959-03-11
Abstract: 884,743. Milling-cutters. GLEASON WORKS. March 11, 1959 [March 27, 1958], No. 8437/59. Class 83 (3). A rotary tool for cutting a non- generated spiral bevel or hypoid gear G of tapering tooth-depth comprises a plurality of groups of cutter-blades 18a-19b, 18c-19d 18e-19e, each group presenting at least one inner and one outer cutting edge, the blades of each group lying along a different helix 21 coaxial of the cutter, and the helices being substantially identical and equally spaced from each other about the tool-axis 12. The tool cuts by the method described in Specification 750,034 and may be used in the machine of Specification 884,741. In the tool of Fig. 1, which is reciprocated in the direction of its axis three times for each of its rotations, the blades 18a-18e, 19a-19e are integral with mounting segments 13 attached by bolts 14 to a conical surface 15 of the tool. Keys 17 locate the segments 13. Adjacent blades cut on opposite sides of a tooth-space, and the offset (i.e. depthof-cut), of each inner cutting-edge is represented in Fig. 2 by a-e, a common helix 21 being assumed for purposes of illustration. Blade 18e cuts to full depth with its inneredge and blade 18d with its top-edge d<SP>1</SP>, extensions of these edges passing through the helix 21. Similarly (Fig. 3, not shown), the outeredge of blade 19e and the top-edge of blade 19d cut to the full depth of the tooth-space. Blades 18e, 19e are spaced so that they do not engage a tooth-space at the same time. Indexing of the gear blank takes place between the last group 18e, 19e and the first group 18a-19b. Offsets and blade-spacings for a finishing tool are given. In a modified three-stroke tool with separate blades, each having locating key and attachment screw (Fig. 5, not shown), the first blade of the first group has an inner cutting- edge while that of the second group has an outer cutting-edge. A four-stroke tool is also described, and a five-stroke tool in which one of the helices is without teeth, thus facilitating indexing of the gear-blank. The surfaces behind the cutting edges are preferably helicoidal, having a helix angle about six degrees greater than that of helices 21.
