Title: Optical switch
Inventor: SAKAKIBARA MASAHIRO
IPC: G02B6/35
Filed: 1982-01-05
Abstract: PURPOSE:To obtain a less-loss optical switch which has improved array precision by providing plastic optical waveguides with curved optical waveguides so that respective light guides cross both surfaces of a base material mutually. CONSTITUTION:Optical fibers 26-29 are connected to the plastic optical waveguides 19 and 20 at a fixed part 24. When a movable part 23 is positioned as shown in a figure, a optical signal from an optical fiber for transmission is supplied to an optical receiver 5 through the optical fiber 26, optical waveguide 19, and optical fiber 27. The optical signal after signal processing is led out from an optical transmitter to the optical fiber for transmission through the optical fiber 28, optical waveguide 20, and optical fiber 29. Then when the movable part 23 moves as shown by an arrow A, the optical signal from the optical fiber 2 for transmission is led out to the optical fiber 2 for transmission again through the optical fiber 26, optical waveguid 21, and optical fiber 29 to obtain a by-pass state.

Title: Electrical automatic speed regulators for internal combustion engines
IPC: F02D1/08
Filed: 1946-01-02
Abstract: 605,665. Automatic speed-control systems. LEONARD, C. A. Jan. 2, 1946, No. 194. Convention date, Jan. 10, 1945. [Class 38 (iv)] In a system for automatically regulating the speed of an internal combustion engine a thermally-responsive element heated in dependence on the engine speed closes contacts at a predetermined engine speed to energize electrical means adjusting the engine fuel supply. In Fig. 1, the throttle 18 of a vehicle internal combustion engine 10 is normally adjusted through a linkage 20, 21 by an accelerator pedal 26 acting against a spring 23. A commutator device 36 (shown in detail in Fig. 5) associated with speedometer cable 32 interrupts the current supplied from the vehicle battery 48 to the primary 42 of a transformer 44, the frequency of interruption being thus dependent on engine speed. The secondary 61 of transformer 44 supplies the heating coil 90 of a bimetallic switch 56 (shown in detail in Fig. 3) and, since the efficiency of transformer 44 increases with frequency, the heating of the bimetallic switch increases with increase of engine speed. At a maximum speed determined by the setting of rheostat 64 contacts 86 and 88 of bimetallic 'switch 56 close to energize from battery 48 an electromagnet 28 (shown in detail in Fig. 2). which, by attraction of its armature 72 against a spring 74, adjusts the throttle position to reduce engine fuel supply. The following modifications are referred to separately and in certain combinations : (a) compensation of the bimetallic switch for ambient temperature changes by mounting contact 88 on a bimetallic strip; (b) replacement of the commutator device by a distributor-type switch or a commutator of the single brush type; (c) a two-way bimetallic switch associated with two electromagnets acting on linkage 20, 21 to provide maximum and minimum limitation of engine speed; (d) an A.C. supply from a tachometer alternator replacing the interrupted supply from the commutator device in which case transformer 44 may be dispensed with.

Title: An alarm clock with mechanical pin release
IPC: G04B23/06
Filed: 1926-01-05
Abstract: 253,862. Kopatschek, K. June 22, 1925, [Convention date]. Addition to 246,812. Alarm mechanism of the mechanical pinrelease type, arranged for signals of short, predetermined duration as in the parent Specification, comprises a stationary annular ring to receive the pins 15 and a releasing lever 6 carried by slot 8 and pin 7 on an arm 5 which rotates rigidly with the hour wheel spindle 1, the lever being pressed outwardly by a spring 16 anchored at 17 to the arm 5. Loose on the hour shaft and next to the hour wheel 2 is a cam 3 rigid with a disc 4 having teeth at its periphery. A pin 11 on this disc co-acts with the end 12 of the lever 6 and another pin 10 on this disc engages in a substantially triangular hole 9 in the lever 6. Passing between the cam 3 and disc 4 is a spring 19 which normally locks the lever 18 of the alarm hammer. When a tooth 14 of the lever 6 in rotating with the hour spindle meets a pin 15 it is rocked by the pin so that its end 12 strikes upwardly against the pin 11 and rotates the disc 4 and cam 3 counterclockwise, Fig. 1, whereby the cam 3 is moved axially by the hour wheel 2, removing the spring 19 from the lever 18. The alarm train now operates and drives a member 21 which, by engaging the teeth of the disc 4, moves the latter further counterclockwise whereby, after a short time, the pin 10 on the disc 4 moves the lever 6 to the right, Fig. 1, and removes the tooth 14 from the release pin 15. As soon as the member 21 is disengaged the parts are returnad by the springs 16 and 19. If there is more than one tooth 14 at the end of the release lever 6 the above operations are repeated for each tooth, giving a succession of short signals.

Patent GB-601202-A (GB)
Title: Improvements in and relating to the production of branched chain alkenes
IPC: C07C5/27
Filed: 1941-01-10
Abstract: Alkenes are converted to more highly branched isomers by contact at 100-600 DEG  C. and a pressure not exceeding 20 atm., in the presence of not less than an equal volume of a diluent, with an acid phosphate of copper or a mixture thereof with an acid phosphate of cadmium or of an alkaline earth metal.  The catalysts may be prepared, for example, as described in Specifications 460,659 and 535,062, by partial neutralization of phosphoric acid with the metal carbonates or oxides or addition of phosphoric acid to the normal phosphates. They can be used in a dry, hard, porous state or on carriers such as active carbon or kieselguhr. Diluents include nitrogen, hydrogen, water vapour, methane, butane or other saturated hydrocarbon, generally in the ratio of diluent to alkene of 1 to 10 : 1, preferably 2 : 1, by volume under the reaction conditions.  Where cracked alkene fractions are used as feedstock, saturated hydrocarbons within the range specified are generally present.  Small amounts of water are preferably also added.  A continuous vapour phase process is advantageous. Normal butene fractions may be treated to increase the isobutene content to, say, 10 per cent, followed by interpolymerization of the butenes, and further isomerization of the residue.  In examples, normal butene with an equal volume of water vapour is passed over copper-cadmium or copper-calcium acid phosphate at about 300 DEG  C. and atmospheric pressure while a normal butene fraction containing an excess of butanes over butenes is passed with water in a mass ratio to hydrocarbon of 0.9 or 0.1 over the same catalysts at 350 DEG  C. and 80 p.s.i.  Specification 496,676 also is referred to.  The provisional Specifications refer to the use of acid phosphates of metals of Groups 1, 2, 3, 4, 6, 7 or 8 with or without normal phosphates.

Abstract: 1418805 Band-pass filters FINOMMECHANIKAI VALLALAT 8 Jan 1973 [7 Jan 1972] 916/73 Heading H1W A band-pass filter consists of at least two resonant co-axial cavities with homologous ends open (or partially open) and facing each other to effect mutual coupling, such coupling being adjustable by relative movement of the cavities. Fig. 7a shows four such cavities each consisting of a quarter-wave resonator having an internal helical conductor 3. The cavities are arranged with earthed and live ends alternately facing each other and adjustably connected by threaded or slidable sleeves 6. Halfwave cavities, either earthed at both ends or earthed at the centre, may be used. Thus, Fig. 10 shows a central half-wave cavity with open-circuited ends coupled to a pair of quarter-wave cavities. In this example, the internal conductors are straight cylinders. Input/output may be of the direct (Fig. 10) type or of the inductive type (Fig. 7a). The outer conductors may be of polygonal section. The relative movement may be axial (as shown), angular or rotational. Thus, a number of cavities may be arranged to form a rotational switch. In another embodiment (Fig. 11, not shown), a number of cavities are arranged sideby-side with homologous ends facing and open to a further cavity through which they are mutually coupled.
