Patent GB-866598-A (GB)
Title: Improved coating compositions
Inventor: INSHAW JOHN LESLIE
IPC: C08F299/04
Filed: 1957-10-15
Abstract: An oil-modified alkyd consists of the reaction product of a preformed oil-modified alkyd and 40-70% by weight of a vinyl monomer, the preformed alkyd being a reaction product of a drying oil, polyhydric alcohol, and at least two dibasic acids of which between 15 and 35% by weight of the acids have the formula HOOC (CH2)n COOH where n is 2-8 inclusive.  The drying oil may be a mixture of linseed and wood oils, or dehydrated castor oil.  The alkyd is preferably based on phthalic anhydride and glycerol or pentacrythritol or glycol or mixtures of these polyols with adipic or sebacic acids.  The vinyl monomer may be methyl methacrylate, mixtures of methyl methacrylate with butyl methacrylate, ethyl acrylate, styrene containing at least 50% by weight of methyl methacrylate, or a mixture of methacrylic acid and methyl methacrylate.  The reaction with the vinyl monomer is generally effected in a solution of the alkyd resin, e.g. xylol, in the presence of a peroxytype catalyst, e.g. tert-butyl peroxide.  The oil-modified alkyd in solution may be used for coating metals.

Abstract: 747,112. Removing bark from logs. McKENZIE, H. K. Feb. 24, 1955 [Nov. 25, 1953], No. 32689/53. Class 145 Bark is stripped from a log by several helical springs 46, 47 mounted in a skeleton drum 32, 35 which is rotated by a belt passing round a pulley 36. The springs have a rubber or like core 43 and may be of round, square or other cross-section; they may be arranged, as shown, on two sides of the log or they may encompass it more closely as, for example, in the form of a triangle. The springs are carried on bars 44, 45 linked to one end 32 of the drum and to a ring 39 sliding on pins 38 on the other end 35'of the drum, the ring being moved to adjust the spacing of the springs by a handwheel 56 and screwed rod 53 connected to the ring by pivoted links 51a, 49 and rollers 53 bearing on each side of the drum. Preceding the spring drum, spring-loaded knives 59 pivoted on the framework cut the bark longitudinally and other spring-loaded knives 62 pivoted on a bar 44 and a bar 45 have deflectors 63 which are engaged by the leading end of the log to adjust them outwards to remove some of the bark. The logs are supported on V-shaped tables 11 and 12 and upper and lower resilientlyloaded spindles 13 and 20 driven through universal couplings have radial sloped lugs 19, 26 that feed the logs and also prevent them from rotating. A spring-loaded plate 67 steadies the log on the delivery table 12. The Provisional Specification describes also helical springs anchored in triangular form to rods having rollers rotated on a spaced pair of fixed cylinders, and feed' means comprising lower screw-adjusted rollers and an upper spring-loaded roller,. the rollers being V-shaped and serrated.

Abstract: 1,151,238. Band clamps. WITTEK MFG. CO. 20 July, 1966 [21 Feb., 1966], No. 32695/66. Heading E2B. A worm drive hose clamp has an elongate, partially slotted band 16, a worm housing integral with one end portion of the band the slotted second end portion of the band being looped through the housing and movable therethrough upon tightening of the band upon a hose connection, a worm 14 disposed in the housing and having threads engageable with the slotted second end portion of the band and means 56 for locking the worm within the housing, the housing, band and locking means all being formed from a single member of sheet metal. As described the housing is formed from two lugs 40 which are bent to define a channel formation through which the slotted end portion of the bases passes and a chamber formation, in which the worm is disposed. The lugs 40 are connected together by a tongue 60 extending from one lug and which engages a notch 62 in the other lug so that edges 48 and 50 of the lugs abut; the butt joint between the edges 48 and 50 can either be in the top of the housing or in one side. The tongue 60 shown is of dovetail shape but a T shaped tongue can also be used. The worm locking means 56 are tabs formed by slitting the lugs 40 and they engage between the head of the worm and its screwthreaded portion. To aid flexibility a passageway (not shown) is formed in the band between the lugs. The slots in the band can either extend completely through it or only partly through it.

Abstract: 656,311. Turning wood-screws. STEINEMANN AKT.-GES., U. Dec. 17, 1948, No. 32752. Convention date, Dec. 17, 1947. [Class 83 (iii)] A steady-rest arrangement for use in cutting screw-threads on wood-screw blanks comprises a rotatable and slidable spindle, parallel to the blank axis, to which the rest is secured which is moved in one direction by a driving member connected to a tool carrier and returned by a spring, an adjustable stop limiting the return movement to a position in which the rest covers the forward end of a new blank, the rest sliding ahead of a cutting tool during the cutting operation and being rocked away from the finished screw by the release of a locking lever and spring means. The tool 9 rotated by worm gearing 7, 8, Fig. 4, from a shaft 5 is supported in a holder on a sleeve-like saddle 3. The latter is reciprocated for the cutting operation by a cam-operated lever 17, the end of which engages a yoke 15 secured against axial movement to an extension of the saddle. Rocking movement of the tool-holder to follow the taper required on the screw is effected by a tracer member 33 sliding over a template 35, the tracer being held on the template by a spring 37. The steady rest 20 is carried by a lever 22 secured to a sliding spindle 23. Axial movement of the latter is effected on forward cutting movement of the tool (to the right, Fig. 2) by a member 25 fixed to the saddle striking a collar 24 on the spindle. This movement is effected against the pressure of a spring 29 which returns the spindle on the reverse movement until its movement is arrested by an adjustable stop collar 28. The steady rest in this position is immediately opposite the end of a work-piece and has been released from contact therewith at the end of the forward movement by a cam 44 and bell-crank lever 41, 40, the latter operating as a latch to hold the lever carrying the rest against the work a short distance ahead of the cutting tool until release takes place when a spring 38 withdraws the lever 22.

A tongue 5 on the carrier 4 slides in either of two grooves 3. The support 1 may be integral with, or adjustably attached to, a shank 2. The tool 10 may be gripped in a circular or square adaptor 12, Fig. 9, to allow angular adjustment about the tool axis. Alternatively, the shank 2 is cranked so that the holder may be adjusted about the tool axis. The holder may support the tool for grinding. The Specification as open to inspection under Sect. 91 comprises also a tool-holder having a straight shank and a set of wedge-shaped carriers to adjust the angle of the tool, (see Fig. 20 (Cancelled)) ; and further comprises the use of a round-nosed tool, (see Fig. 2 (Cancelled)) This subject-matter does not appear in the Specification as accepted.

One edge 31a of the depression is determined by cam 33 which is fixedly secured to the drum shaft (the front edge 23a of the copy is always placed in a fixed position abutting studs 19), and the other edge 33a is determined by cam 33 which is adjustable angularly in accordance with the rear edge of the copy by a pointer member 25. This member is freely mounted on the drum shaft, but carries a detent and is spring-urged into engagement with a gear 25 on the shaft at whatever position it is adjusted. The blanking operation may take the form of short-circuiting the transmitter output, Fig. 6 (not shown), or, in the event of scanning negative copy, the replacement of the transmitter output by a white-level signal from a separate source, Fig. 7 (not shown).
