IPC: B27H3/02
Filed: 1919-09-30
Abstract: 146,015. Olsen, H. O., and Nilsen, O. Sept. 30, 1919. Wood, shaping by cutting; planing.-In a machine for shaping cask staves of the kind in which vertically-movable rotary cutters with inclined cutting-faces act on the sides of the stave, the cutters are mounted on pivots and are moved outward by contact of the stave with pivoted blocks. These blocks 50, 51, Fig. 2. are linked to a shaft 57, carrying an arm with a slot which engages with an arm 61, Fig. 5, on a ratchet wheel 62, connected by links 65, with the bearings 34 of the shafts 32 of the cutters 30. Outward movement of the blocks 50, 51 is thus communicated to the bearings 34, which are mounted on pivots 36, in the lower framework. The shafts 32, are free to move longitudinally in relation to the bearings 34, the movement being controlled by members mounted eccentrically on a vertical wheel 67 rotated by engagement with the lower face of the stave. Balls 75 carried at the ends of the eccentric members engage with slots in framing 79 which moves with the shafts. The upper face of the stave is shaped by horizontal cutters 24 and cutters (not shown) are provided to work on the lower face. Pivoted blocks 13, 14 linked together in a similar manner to the blocks 50, 51 guide the work to the cutters.

Patent GB-762152-A (GB)
Title: Novel polypyromellitimides
IPC: C08G73/10
Filed: 1954-08-20
Abstract: Polypyromellitimides of nonamethylene diamine, 4,4-dimethylheptamethylene diamine or 3-methylheptamethylene diamine (see Group IV (b)), have properties, particularly toughness, retention of toughness on heating, stability under oxidizing conditions, suitable melt viscosity and a high "glassy state transition temperature" which render them particularly suitable for injection moulding.  The "glassy state transition temperature" is defined as the temperature at which many physical properties undergo a sharp transition, e.g. the stiffness suddenly decreases. Preferably the initial stage of the reaction is performed under a blanket of inert gas by mixing equimolar amounts of the diamine, and the tetra-acid, the di-anhydride or the acid ester (e.g. diacid diester) in a solvent which may be an aqueous alcohol to form a salt. The solvent is then evaporated, leaving an aqueous mixture which is then heated to complete polymerization.  A number of examples are given of preparation of the polymers and their physical properties are tabulated. Specifications 570,858 and 627,205 are referred to.ALSO:4.4 - Dimethylheptamethylenediamine is prepared by reacting isoprene with 2 mols. of hydrogen chloride and treating the isoprene hydrochloride with ethylene and aluminum chloride at - 20 DEG  C. The 3,3-dimethyl-1,5-dichlorpentane so formed is cyanated with sodium cyanide in refluxing tetrahydrofurfuryl alcohol and the 4,4-dimethylpimelonitrile catalytically reduced to the diamine. Nonamethylene diamine is prepared by heating azelaic acid at 300 DEG C. in gaseous ammonia with polyphosphoric acid as a catalyst.  The azelao-nitrile is hydrogenated to the diamine with a cobalt catalyst. 3 - Methylheptamethylenediamine.  Isobutylene and acrylonitrile reacted under pressure give 2 - methyl - 1 - pentenonitrile which is mixed with diethyl ether and reduced cobalt oxide catalyst and treated with a mixture of carbon monoxide and hydrogen to give 6-cyano-3-methylhexanol which is subjected to reductive amination in presence of ammonia, hydrogen and reduced cobalt oxide catalyst to yield 3-methyl heptamethylenediamine (B.P. 53-60 DEG  C. at 0.4-0.6 mms.).

Abstract: 652,731. Knitting. STOLLE, F., STOLLE, H., and PEJSEK, A. Aug. 20, 1946, No. 24768. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 20, 1946.] [Class 74 (ii)] In making elastic fashioned articles (such as body belts, bandages, girdles and corselets) on a warp knitting-machine, the warp threads are divided into zones (e.g. A, B<SP>1</SP>, C) located side-by-side, by omitting needles of one row over small spaces D, feeding warp threads to the other row of needles only over these spaces and laying in, in one or more zones, elastic and nappable or non-nappable non-elastic weft threads to extend in straight lines between the warp-knitted courses. The wefts are introduced through guides F<SP>1</SP>, F<SP>2</SP>, the guides Fl reciprocating more quickly than the guides F<SP>2</SP>; and the articles are fashioned by varying the tension of the elastic wefts GS and by the size, nature and'distribution of the elastic and non- elastic zones. The tension is varied by holding the elastic yarn for varying periods during laying-in, to produce differing degrees of subsequent contraction and the frequency of the weft insertions may be varied, as between zones I, II and III of Fig. 4. Separating courses Tr, between the articles, are formed by omitting weft threads within nappable zones A and laying them in after every fourth course only in the other zones. The warp threads may be of rubber, cotton, cellulose, or silk and individual warps may differ. The rubber thread of the elastic wefts may be covered with cotton, cellulose or silk. The non-elastic wefts may be of cotton, cellulose, wool or waste yarn and be covered with fancy thread (e.g. artificial silk). The nappable wefts are of readilyteasable cotton, cellulose, or wool. Selvedges serving as sewing strips may be formed in the same way as are the inter-zonal parts D.

Title: Improvements in artificial limbs
IPC: A61F2/60
Filed: 1919-10-10
Abstract: 156,887. Trautman, R. Oct. 10, 1919. Limbs, artificial. - Artificial legs comprise hollow shells formed of fibre moulded into a shape of standard size, and having longitudinal edges which may be overlapped to any required extent and secured by rivets, so that a limb of any required size may be formed. The length nf the casings may be adjusted by cutting. An ankle block secured to the shank member is spaced from the rear thereof so as not to interfere with the amount of overlapping of the shell. The thigh member 114, Figs. 2 and 5, is overlapped at the rear to the required amount and rivetted at 120, and is secured to a knee block 160 the upper end of which is reduced to fit the adjusted shell. A leather lining 172 is similarly overlapped. The knee block 160 is pivoted by means of a pin 166 to mteal strips 158 secured to the shank member 116, and is slotted to receive a pivoted bar 176, Figs. 2 and 3, the lower end of which is secured to an elastic strip180 supported by cords 182 from the top of the shank member. A rubber buffer is placed on the rear of the lower end of the bar 176 to form a cushion between the bar and the shank member. Strips 128 secured inside the lower end of the shank member 116, Figs 6 and 7, carry a sleeve or bushing 132 which is spaced from the rear of the shell 116 so as to allow of the necessary adjustment by overlapping. A foot 118 is connected to a cylindrical member 134 within the sleeve 132, by means of a bolt 136 passing through a slot in the sleeve. A spring or other elastic member 150 and a rubber buffer 152 control the movements of the foot. The rear portion 156 of the foot may be cut away to adjust it to the size of the shank according to the amount of the overlapping in any particularly case. Figs.10 and 12 show a modification for cases of amputaion below the knee in which an inner socket 192 is adjustable by lacing to the adjusted size of the outer shell. The fibre employed in making the shells is prepared by chemical treatment of cotton or linen cloth and is not bleached or coloured. Sheets of fibre are softened by prolonged soaking in water before moulding to the required shape.

Abstract: 836,027. Non - contact - making relays. SPERRY RAND CORPORATION. Aug. 17, 1956 [Aug. 18, 1955], No. 25251/56. Class 40(9). A circuit in response to a binary input produces one output representing the binary input and another output representing its complement and comprises a transformer T which has a winding 11 connected at one end to a source of clock pulses and at the other end to an output terminal 18, a winding 12 connected to an output terminal 20, and a winding 10 which is open or short-circuited under control of the binary input. In Fig. 1 a switch, shown as a transistor, is connected across winding 10 and on receipt of an input pulse 16 the winding which is normally open circuit is short-circuited. Input pulses, if they occur, coincide with negativegoing clock pulses. If, with no input pulse, winding 10 is open circuit, winding 11 has a large impedance and a voltage is induced in winding 12 to give an output at 20 representing the complement of the input, output 18 being held at earth potential by rectifier D3 and a constant current source 19. If winding 10 is short-circuited by an input pulse, winding 11 has a low impedance and no output is induced in winding 12, rectifier D3 being cut-off by the negative clock pulse to give an output at terminal 18. The winding 10 may be open-circuited by the input pulse and positive clockpulses may be used with positive input pulses.
