Title: Method of baiting  hooks and apparatus for carrying out the  method
IPC: A01K97/00
Filed: 1974-11-26
Abstract: 1457689 Apparatus for baiting hooks MUSTAD INDUSTRIER A/S 26 Nov 1974 [7 Jan 1974] 51049/74 Heading A1A An apparatus for baiting hooks 2 attached to a line 4 by means of a snood 3 comprises a hook guide 1, retaining flap 5 mounted at 6 on frame 7 to pivot in the advance direction of hook 2 against the action of tension spring 8, a finger 13 mounted transversely of the hook guide, and arm 9 mounted at 10 to be raised against the action of spring 11 for the introduction of a bait piece 12. The bait piece is retained by a stepped portion 1' of the upper side of the hook guide 1. As the hook 2 is drawn through the apparatus the inner surface of its curved part engages finger 13 which projects inwardly above path 16 of the hooks 2 in hook guide 1, and pivots against the action of spring 15 thereby slowing the movement of the hook and tightening, both snood 3 and line 4 so that the hook 2 enters the bait piece 12 at reduced speed. The finger 13 with the inner surface of the hook 2 forms a cross-shaped bearing surface for the bait piece 12. As the hook 2 enters the bait piece it rotates to the position indicated by broken lines in Fig. 1 due to the positioning of the lower edge of the flap 5 with respect to that of the cross shaped bearing surface, forcing the hook through the back portion of the bait piece. Return movement of finger 13 serves to actuate means (not shown) for feeding a fresh bait piece to the bait holder with displacement of any bait piece too soft to be conveyed to the hook.

Abstract: 1410636 Automatic control of electro-erosion ING C OLIVETTI & C SpA 8 Nov 1972 [9 Nov 1971] 51600/72 Heading G3N [Also in Division B3] An electro-erosion machine having a wire electrode tool extending between two tool supports comprises means responsive to the relative movement between the tool supports and a workpiece table along two co-ordinate axes for relatively adjusting the tool supports to incline the wire electrode to enable a raked cut edge to be produced. In one embodiment, the machine's control apparatus, which is similar to that described in Specification 1154761 comprises an interpolator 97 connected to a punched tape reader 96 supplying the co-ordinates of the workpiece tables and to an adaptive control unit 98 for modifying the speed of the tables computed by the interpolator 97 as a function of the voltage between the wire electrode and the workpiece. Depending on the sign of the output signals of the interpolator 97, gates 102, 103, 108, 109 are enabled to cause valves 92-95 to open which in turn cause movement of the tool supports to incline the wire (see Division B3). In another embodiment Fig. 15 (not shown), the output signals of the interpolator 97 are fed to a resolver (260) via registers (266, 267) and converters (268, 269) timed by an oscillator (270). An output error signal from the resolver (260) is fed to a motor (257) which rotates a sleeve (151) causing the tool supports to move to incline the electrode. During rotation of the sleeve (151), the rotor of the resolver (260) is rotated by gears (157, 262) until the error signal is nullified.

Patent GB-535428-A (GB)
Abstract: 535,428. Cash registers. KOOPERATIVA FORBUNDET FORENING U.P.A. Oct. 13, 1939, No. 27828. Convention date, Oct. 22, 1938. [Class 106 (i)] A tens transfer device for overflow wheels of totalizers in cash registers and like calculating machines has a totalizer wheel shaft 1 movable laterally for bringing the ordinary totalizer wheels 15 into and out of mesh with the differential setting members 5, characterized in that the tens transfer toothed wheels 13 are mounted on a stationary shaft 11, that the overflow totalizer wheels 19 are adapted to be in engagement with the toothed wheels 13 when the ordinary totalizer wheels 15 are in driving mesh with the differential setting members 5 and that said toothed wheels 13, when the last-mentioned totalizer wheels 15 leave their driving mesh with the differential setting members, are lockable in set position by means of a locking device 20 participating in the lateral motion of the totalizer wheel shaft 1. The invention is described in connection with Specification 410,974 in which the ordinary totalizer wheels 15 are set by racks 5 which receive an extra step for tens transfer. The totalizer shaft 1 is carried by sledges 2 moved to the right, as shown in Fig. 1, to engage the totalizer with the setting members and the transfer wheels 13 at the same time. When a wheel turns from " 9 " to " 0," its trip tooth 18 drives transfer wheel 13 and hence the wheel 19 of the next higher denomination, and as the totalizer is withdrawn, a member 20 secured to sledges 2 engages between the teeth of wheels 13. The overflow wheels each have a ratchet 17 and a spring detent 16. Since the transfer members are already out of engagement with the totalizer wheels, zeroizing is thereby simplified.

Abstract: 1293237 Polyurethane foams FARBENFABRIKEN BAYER AG 13 Nov 1970 [17 Dec 1969] 54086/70 Headings C3C and C3R Polyurethane foams are prepared by reacting, in the presence of a blowing agent and a catalyst for the reaction, a hydroxyl-group containing polyether which contains at least 10% primary OH groups and has a M.W. of 3500 to 10,000 with a biuret-containing polyisocyanate dissolved in a monomeric polyisocyanate at a concentration of 1 to 85% by weight. The polyether is suitably prepared by reacting an alkylene oxide with a compound which contains reactive hydrogen atoms followed by reaction with ethylene oxide to introduce the primary hydroxyl groups. Other compounds having reactive hydrogen atoms may be used in admixture with the polyethers. The biuret containing polyisocyanates are prepared preferably by reacting a monomeric polyisocyanate with water or formic acid, and are then dissolved in monomeric polyisocyanates or are suitably prepared using excess monomeric polyisocyanate in which case the required mixture is produced in one-step. Solutions containing urethane-containing polyisocyanates or isocyanate-containing polyisocyanates as well as the biuret-containing polyisocyanate in monomeric polyisocyanates are particularly suitable. In a typical example a mixture is prepared from a propylene glycol/ trimethylolpropane/ethylene oxide polyether, ethylene glycol, monofluorotrichloromethane, 1 - dimethylaminoethyl - 4 - methylpiperazine and endoethylenepiperazine and is reacted in a closed mould with a biuret-containing polyisocyanate mixture prepared by reacting 2,4- and 2,6-toluylene diisocyanate with water.
