Title: Improvements in and relating to the manufacture of viscose artificial silk
IPC: C08K5/101
Filed: 1930-05-09
Abstract: Viscose silk of diminished lustre is produced by incorporating in the spinning solution a small proportion of a difficulty hydrolyzable ester of a hydrogenated phenol and a mono- or poly-carboxylic acid. The ester, which may be added alone, or together with an emulsifying agent, or as a preformed emulsion, is preferably present in a quantity corresponding to 1 per cent or less in the viscose. Suitable esters referred to are methyl-cyclohexanol esters of cinnamic acid, methyl adipic acid, and of fatty acids such as oleic, stearic, or palmitic acids.  In examples, (1) the ester of methylcyclohexanol and methyl adipic acid is dissolved in the carbon disulphide used in the preparation of the viscose, (2) the ester from commercial stearine and cyclohexanol is added to the vessels whilst the cellulose xanthate is being dissolved.

Title: Light- and heat-sensitive recording materials and information recording processes using such materials
Inventor: VRANCKEN MARCEL NICOLAS
IPC: G03G5/02
Filed: 1963-12-05
Abstract: 1,139,896. Light and heat-sensitive materials. GEVAERT PHOTO-PRODUCTEN N. V. Jan.5, 1965 [Dec.5, 1963], No.14285/68. Divided out of 1,139, 891. Heading G2C. A light and heat-sensitive material comprises a heat-sensitive layer of a hydrophilic binder in which are dispersed hydrophobic particles of polyethylene, polyvinylidene chloride or polyvinylcarbazole and also containing silver halide so that on exposure to light and development (if necessary) to produce a silver image, exposure to uniform infrared radiation will render the heat-sensitive layer less water-permeable in the infrared absorbent silver image areas. The silver halide may be in the heat-sensitive layer or an adjacent layer. The material, which has been rendered selectively less water-permeable, may be further developed as set out in parent Specification 1,139, 891. In the examples, a paper support is coated with either (i) a gelatino silver halide print-out emulsion or (ii) a gelatine layer containing a pyrazolidinone developer and a silver halide emulsion to produce a heatdevelopable material, and overcoated with a heat-sensitive gelatine layer containing dispersed polyethylene particles, imagewise exposed to light and heated (in the second material) to produce a silver image, uniformly exposed to infrared radiation and developed by (i) applying an aqueous dye solution, (ii) pressing against an art paper to remove water-permeable areas and exposing the remainder to light to produce a positive silver image or (iii) pressing against a carbon sheet to transfer the carbon to the waterpermeable areas and producing a spirit duplicating master.

Title: Improvements in or relating to dividing round timber logs
IPC: B27L11/00
Filed: 1961-04-20
Abstract: 926,090. Sawing and chipping wood. K. LINCK, [trading as GEBR. LINCK MASCHINENFABRIK UND EISENGIESSEREI GATTERLINCK]. April 20, 1961 [April 21, 1960], No. 14377/61. Addition to 853,929. Class 145. The combined chipping and sawing machine of the parent Specification, for converting a log into chips alone or baulks and planks alone or both, has differently arranged cutting tools and different means for supporting the log. As shown in Figs. 1 and 3, two staggered pairs of side-milling cutters 24, 25 and 26, 27 are mounted on slides 31, 35 fed transversely across the stationary log by hydraulic cylinders 49, 56. The cutters are driven by separate electric motors and their distance apart is adjustable by threaded shafts 38. The log is supported on two carriages which run on rails 1 and have three clamping jaws 19 or resiliently-mounted rollers pressed against the log by hydraulic cylinders 11. The step-bystep advance of the log may be controlled in dependence on the movements of the chipping tools. After being squared by the chipping tools, the baulk is cut into planks by a frame saw 73 which has upper and lower feed rollers 70, 71 on either side of it and has the saw blades 74 adjustable to vary the plank thickness. If the baulk is not to be cut into planks, the blades are adjusted apart to allow a clear passage or a transfer device is arranged to by-pass the saw. The chipping tools may chip the log on two opposite sides and then the log is turned through 90 degrees to be chipped on the other two sides by a second set of tools. Fig. 4 shows alternative tools B, C of the endmilling type which are rotated and fed axially by hydraulic means D<1>, E<1> and Fig. 6 shows cutters G, H with spirally arranged teeth which can chip a continuously fed log and are axially adjustable for depth of cut. Chain-type and reciprocating tools, elliptical motion of the tools and staggering of the tools in the longitudinal direction of the log are also referred to. The tools may have scoring blades and planing knives and breaking edges for dividing chips which are too long. Several tools may be mounted on a turret head on movable slides or the turret support may itself be traversable.

Further correction of the above output is achieved by comparison with ##0 in a discriminator 40, Fig. 4, the discriminator output being applied to the grid of a cathode follower 45 having its cathode resistor shunted by the secondary of a transformer 48 to which the output Ka 1 a 2 Cosα Cos2#ft from adder 32 is also applied. The secondary is connected in series with a condenser 51 and the corrected output is taken from the centre tap.

Title: Fastener applying device
IPC: B25C1/04
Filed: 1972-03-28
Abstract: 1340450 Fastener driving tool SENCO PRODUCTS Inc 28 March 1972 [25 Aug 1971] 14476/72 Heading B4C A pneumatically operated fastener driving tool comprises means whereby a fastener driving piston can perform a single driving stroke and a single return stroke each time the tool is actuated by depression of a trigger. A movable valve stem 70 in its non-actuated position coacts with a movable valve sleeve 58 to permit passage of air in reservoir 16 via ports 68, 69 and 56 and bore 28 to the upper surface of a main valve 26 so that the main valve is maintained in contact with the upper end of cylinder 18, thus venting the cylinder space above the piston. Depression of the trigger 32 moves the stem relative to the sleeve into a position in which sealing ring 74 engages bore 64 to prevent supply of air to the main valve upper surface and ring 76 no longer sealingly engages the bore 64. Thus the space above the main valve is vented via bore 28, ports 56, 69 and space 66 to atmosphere. The air in the reservoir causes the main valve to move away from the cylinder and air from the reservoir drives the piston 20 on a working stroke. At the end of the working stroke, air from the reservoir passes via bores 34 into a return reservoir 36 and also into chamber 44 via passage 38 and a check valve 40. Air supplied to the chamber 44 causes the sleeve to be moved to the position of Fig. 5 in which air from the reservoir 16 can again pass to the space above the main valve 26. The main valve now returns to its initial position and the cylinder space above the piston is vented. Air within reservoir 36.effects return of the piston. Flats on driver 22 permit venting of the cylinder space below the piston and reservoir 36 via the fastener drive channel. The sleeve 58 is maintained in the position of Fig. 5 until the trigger is released, thus permitting venting of the space 44 via space 48a and grooves 104. A valve body slidably mounted in a bore intersecting the passage 38 may include, besides the check valve, a solid blocking portion and a portion provided with a through bore. With the passage blocked, the piston will only be moved on a driving stroke upon each depression of the trigger, return being effected upon trigger release, and with the through bore coincident with the passage, the tool will continue to recycle if the trigger is retained depressed.
