Title: Machine for tying fishing hooks
Inventor: ROSSELET JEAN
IPC: A01K91/04
Filed: 1968-10-25
Abstract: 1,247,698. Fish hooks. J. ROSSELET and P. A. C. DUVILLARD. 25 Oct., 1968 [28 Oct., 1967], No. 50774/68. Heading A1A. [Also in Division B3] A machine for tying hooks comprises a central bar 30 having a longitudinal passage 36 for the extremity of a linking thread 37 and an adjusting recess 34 for a hook 35, a support shaft 18 for a spool 20 of binding thread 22 coaxial to the central bar 30 and helically movable about the bar, the shaft support having a guide 23 for the binding thread 22; a clamp 54 serving to maintain the hook 35 in-the recess 34 and a mechanism for closing the binding having an axially movable eyelet 44 for pulling the free extremity of the tying thread 22 under the coils of thread surrounding the hook. During operation the end of the linking thread 37 is pulled along hook 35 while the thread of the tie is held manually in front of the hook by its end 57. On starting motor the stock 3 moves to the left, making a helical movement which winds the tie line 22 on the hook and enclose the free end 57 of the tie line. The motor is then stopped with the tie line occupying position 58. (see Fig. 11) and the free end of the tie line cut at 59. The tie line 22 is then wound up to position 60, the linking wire cut at 61 and the tie line wound up to 62, where the closing mechanism is moved to the left by means of a handle 43. This advances the eyelet 44 over coils of the tie line 22. The tie line is then  wound on eyelet 44 up to portion 64 (see Fig. 13) where a hook 65 is passed through the eyelet hooking the thread 64 which is pulled to position 66. The closing mechanism is moved to the right so that the eyelet 44 pulls the strand of the line 66 under the last coils of the tie and the line is then cut.

Abstract: A reinforced polymer comprises an organic polymeric material and a mineral reinforcing agent, the latter being chemically bound to the polymeric material by a silane having the general formula <FORM:1097678/C3/1> in which X is a halogen atom or an alkoxy group, each of Y and Z is a hydrogen atom or a hydrocarbyl group, R is an alkylene group having at least 10 carbon atoms, an alkenylene group or a cycloalkane group, a is 1, 2 or 3, b is 0, 1 or 2, c is 1, 2 or 3 and the sum of a, b and c is 4, e is 1 when R is an alkylene or alkenylene group or 1, 2 or 3 when R is a cycloalkane group. Preferred polymeric materials are polyamides, particularly polycaprolactam or polyhexamethyleneadipamide, and a polymer of an olefinic monomer when the silane contains an alkenylene group. The compositions are prepared by reacting a silane of the above formula either (a) with a functional group present in said mineral reinforcing agent, or (b) with a functional group present in a polymerizing monomer or prepolymer and then reacting a product obtained by a treatment under (a) with a monomer or prepolymer which is a precursor of an organic resinous material, which monomer or prepolymer contains a functional group reactive with said silane or reacting a product obtained by a treatment under (b) with a functional group present in said mineral reinforcing agent.  The silanes in which the alkylene group has 10 to 20 carbon atoms or the alkenylene group has 2 to 20 carbon atoms are claimed as novel compounds.  In the examples are used, as mineral reinforcing agent: mullite, calcium metasilicate, feldspar and wollastonite; as prepolymer material: alkali-catalysed e -caprolactam and a reaction product of a low molecular weight polycarbonate (prepared from bisphenol A and phosgene) and maleic anhydride; as silane: methyl 11-(trimethoxysilyl) undecanoate, ethyl 12 - (triethoxysilyl) tetradecanoate, n - butylb  - (methyldichlorosilyl) acrylate, n - butylb  - trichlorosilyl acrylate and ethyl - b  - trichlorosilyl acrylate.  In several examples a polyfunctional isocyanate promoter is added to the polymerization mixture, e.g. an 80/20 mixture of 2,4- and 2,6-diisocyanato-toluene. Glass fibres are also incorporated in Example 7.

Abstract: 1522146 Multistable state circuits AEP INTERNATIONAL Ltd 2 Dec 1975 15 Dec 19741 52752/74 Heading H3T Manual actuation of a push button switch PB I, Fig. 1 causes a signal via 22 to an input of an associated bistable BS1 and causes by means of a monostable 1C7A and 1C7B, Fig. 2 signals to be applied to the inputs of bistables BS1-BS10 such that the bistable BS 1 is set, the remaining bistables are maintained in or restored to a reset condition and a switching circuit Q1 associated with the set bistable is operated. Set and reset pulses are obtained from monostables 1C7A and 1C7B, Fig. 2. A reed relay REL 1 associated with the selected bistable connects inputs 1, 2 to a single output 31, 32. A lamp associated with the selected push button switch PB1 is lit. Diodes D1-D10 protect the transistors Q1-Q10 against transients induced in the relay winding. In a modification (Figs. 4-6 not shown) the transistors Q1-Q10 are replaced by logic elements (1C6A, 1C10B). In a further modification (Figs. 7-9, not shown) integrated circuits (1C1-1C3) each provide four bistable devices. On actuation of a switch a signal via (107) triggers a monostable which provides a pulse at (108) to all the bistables. Also the actuated switch changes the polarity of the voltage applied to one input of the selected bistable from 0 to + V and the pulse from 108 causes the selected bistable to be set and resets the bistable that was previously in the set state. The selector switch arrangement can be used to connect outputs of sensors such as thermocouple, resistance thermometers or other element to a common output to a read out instrument.

A field deflection circuit is driven by a control signal having sawtooth and parabolic components, the circuit being directly coupled to deflection coil 20 and having a direct current negative feedback path arranged to provide selective attenuation of low frequencies in the output. As shown, the output of a sawtooth generator 1, synchronized by field pulses 4, is integrated so as to provide a parabolic component giving a composite waveform 2 which is passed via an optional capacitor 5 and a driving transistor 7 to a complementary transistor output stage 12, 13 feeding field deflection coils 24. The scan is linearized by feedback via a highpass filter 20, 21. A direct current feedback path is provided via resistor 28 so as to minimize the effect of sudden changes in amplitude from source 1. Transistors 12, 13 operate in class B push-pull, the standing current being adjustable at 30. A negative temperature coefficient resistor 11 provides temperature compensation for the output transistors 12, 13. A diode 17 and capacitor 18 permit free oscillation of the deflection coil 16 during the flyback. If capacitor 5 is omitted, attenuation of low frequencies may be achieved by a resistance/capacitance emitter circuit for transistor 7. Modifications.-The collectors of transistor 12, 13 may be commoned instead of their emitters. Output transistors 12, 13 may be of like conductivity if a driver transformer or a complementary pair of driving transistors is provided. Driver transistor 7 may be omitted or replaced by an FET. Transistor 13 may be replaced by a choke.
