Title: Improvements in and relating to vehicle direction indicators
IPC: B60Q1/36
Filed: 1934-03-26
Abstract: 435,803. :Road - traffic signals on vehicles. OSHEI, W. E., and TRICOFOLBERTH, Ltd., Great West Road, Brentford, Middlesex. March 26, 1934, Nos. 9470 and 20713. [Class 118 (ii)] A semaphore arm is raised to indicating position by one power unit and retained in that position by the power of an independent unit. The latter unit may also assist the former in raising the arm. In the form shown in Fig. 1, a suction unit 12 operates the arm 10 through the piston 13 and bar 15 adapted to descend upon a pin 16 carried by the arm. Normally, the piston and bar are kept slightly raised by a leaf-spring 22 interposed between the bar and the pin, so that the bar locks the arm in its lowered position. The suction is controlled by a slide valve adapted to place the cylinder above and below the piston in communication with the atmosphere and the engine intake alternatively so that the arm may be operated positively in both directions. To retain the arm raised an electromagnet 17 is energized by the shifting of the valve to operating position so that when the piston has descended an iron washer 14<a> engages and is held by the magnet. At the same time a contact 21 may engage a contact 19 rendered live by the bridging of contacts 19<a>, 19<b> by a washer 14b so as to complete circuit for a lamp on the arm. In another arrangement, Fig. 4, two coaxial solenoids 43, 44 are energized together for raising the arm and a switch 50 in the circuit of the outer, or high-powered, coil is automatically opened by the core 45 acting through a spring- controlled plunger 51. In another modification, the retaining coil is disposed end-on to the operating coil, the circuit of which is broken, as in Fig. 4, when the core has descended.

Filed: 1941-07-29
Abstract: 552,317. Automatic control systems for high frequency oscillators. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips Gloeilampenfabrieken). July 29, 1941, No. 9658: [Class 18 (iv)] Frequency  and phase:-An oscillator 2 in a carrier wave telephone system for example, which is synchronized by an oscillator which is or is obtained from a harmonic of a control oscillation of the same frequency, or is obtained from such a harmonic and from a harmonic of the controlled oscillation, has the control suppressed automatically until the oscillator has drifted into exact phase synchronism. Auxiliary oscillations, which are or are equal to harmonics of the controlled, frequency, and the phases of which are respectively dependent on the phase of the oscillation under control and on the controlling oscillation, are applied to the grids of discharge valves 45, in parallel in the circuit of a transformer 6 and arranged to give rectangular wave outputs. Only when these auxiliary oscillations are 180 degrees out of phase with each other is the voltage at the secondary of the transformer below the threshold voltage necessary to render the valve 7 conducting. Only in this case, corresponding to phase synchronism of a definite harmonic of the oscillator with the controlling frequency, is a relay 8 de-energized to permit the controlling frequency to act directly upon the oscillator, as by means of a resistance across which if is applied. A method of obtaining the respective auxiliary harmonics from two harmonics derived from the oscillator and from the control: frequency is described. A method is also described of applying simultaneously to the resistance 3 two control frequencies each equal in frequency to oscillator frequency from two pairs of harmonics of the oscillator frequency and of the control frequency so that should any one harmonic be suppressed by interference a control frequency would still remain operative.

Filed: 1927-04-08
Abstract: 293,484. Johnson, Hodgkinson, & Pearson, Ltd., J., and Taylor, P. April 8, 1927. Pile-fabric looms; terry-forming.-In order that the loop-forming devices may be controlled by pattern surface mechanism which dwells for long periods, a lever 8 for controlling the terryforming mechanism is connected by a rod 7a to a lever 7 pivoted at x. This lever is acted upon by a bowl 5a in the vertical arm of a three-armed lever 5, which is actuated by flexible connections or slotted rods 4, 4<a> from two dobby draw-catches 2, 2<a>. When the lever 5 has been turned by the catch 2a to the position shown in dotted lines in Fig. 1, further operation of the catch 2a has no effect on the lever 5, the bowl 5<a> allowing the right hand end of the lever 7 to fall so that the other end of this lever raises the rod 7<a> and lever 8. At the beat up, this lever engages a pin 10 on a shaft 11 and turns this shaft against the action of a spring whereby the reed arm 11<a> is actuated to form terry. A bowl 20 on a pin or a wheel on a shaft driven from the tappet shaft acts on the lever 7 every fourth or other pick to make the reed fast to beat up the three or other number of loose picks whilst terry is being formed. The terry formation continues until the other draw catch 2 is operated whereupon the lever 5 is moved into the position shown m full lines and terry formation ceases until the catch 2a is again operated. When a dobby with horizontal catches is used, these are connected by bell-crank levers to the slotted rods &c. The catches 2, 2a may be controlled by the body and border pattern surfaces respectively. Letting-off warps. - The three-armed lever carries a second bowl 5<c> to actuate a lever 14 connected by a rod 14a to a lever 15 for operating the friction let-off rope &c., so that when terry is being formed, the friction let-off mechanism is released. The Provisional Specification refers to the use of the three-armed lever for controlling the let-off to produce fabrics with crinkled effects.
