Title: Improvements in or relating to Light Projection Apparatus.
Inventor: AMES ADELBERT
IPC: F21V5/00
Filed: 1916-12-06
Abstract: 111,041. Ames, A. Dec. 6, 1016. Vehicular lanterns.-In an automobile or like headlight, the source of light is positioned with respect to the focus of the reflector so as to obtain a concentrated horizontal beam with a slight divergence, the rays of light from approximately one half of the reflector being reflected horizontally or downwardly whilst those rays from the other half of the reflector, which would otherwise be projected upwardly, are deflected downwardly by refracting-means interposed in their path after they strike the reflector. In one form, the refracting-means comprise horizontally disposed prisms 112, Fig. 3, arranged on the upper part of the lantern front and extending in some cases below the lamp bulb. The V-shaped or conical light source 122 is arranged behind the focus of a paraboloidal reflector P with its apex in the focus, and the centre of the lamp bulb is behind the filament. A depending reflecting or non-reflecting apron 113 having horizontal extensions 114 on each side of the lamp bulb prevents light, which radiates horizontally, from being reflected upwardly. In a modification, the prisms 103, Fig. 2, are arranged concentrically, and the intermediate part of the glass front may be frosted as shown at 106. In the same modification, the lower leg of the V.shaped light source is arranged along the axis of the reflector. In a second form, the source of light is in front of the focus of the reflector instead of behind it, and the prisms are arranged on the lower instead of the upper part of the glass front, the apron extending upwardly instead of downwardly. The centre of the lamp bulb is in front of the filament. Specification 108,988 is referred to.

Abstract: 476,215. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. Feb. 19, 1937, No. 5030. Convention date, April 10, 1936. [Class 40 (v)] Relates to direction-finding systems . of the kind in which a rotating beam is combined with a non-directive radiation which is continuously modulated, so as to enable an automatic indication to be given of the position of a mobile receiver by a method of phase difference. The invention consists in means for rendering such a system useful only to authorized listeners. The rotating beam is radiated from an aerial, 1, Fig. 1, provided with one or more reflectors 3, It has a carrier frequency f 1 modulated at TR1 by a note frequency F1, and rotates at a speed of from 10 to 20 times a second. A non-directive aerial 4' radiates a wave of frequency f2 (slightly higher or lower than f1) modulated at TR2 by a note frequency F2 and sub-modulated at a frequency F3 of from 10 to 20 cycles, related to the speed of rotation of the beam. At the mobile receiver, Fig. 2, the incoming frequencies Fl, F2 are separated out by filters 10, 11, rectified at 12, 13 and fed to a phasemeter 14 which indicates the required bearing. In order to ensure secrecy, a pre-determined variation in the phase of the modulation is introduced, say by means of a clock-driven cam at TR2 in Fig. 1, and a similar cam device is carried by the mobile receiver to correct the phasemeter 14.

Title: Improvements in or connected with Continuous Brake Apparatus for Trains.
Inventor: WARD HORACE FUTCHER
IPC: B60T13/46
Filed: 1917-04-20
Abstract: 113,189. Ward, H. F. April 20, 1917. Fluid-pressure. - Track-controlled valve mechanism for railway-train brakes is adapted intermittently to open and close the train-pipe to atmosphere to secure a gradual application of the brakes. The valve mechanism may be arranged to actuate means for shutting off steam on the locomotive. Fig. 3 shows the mechanism for a compressed air brake system. The train-pipe b is connected to a valve box a in which work a pair of pistons d for controlling venting slits e. The pistons d are actuated by differential pistons f, f<1>. The cylinder g of the larger piston f is connected directly to the valve box a by the pipe k and the cylinder g<1> of the piston f<1> is connected by the pipe l to a reservoir m connected through a restricted passage o to the valve box a. The preesures are normally equalized and the valve tends to move upwardly to the open position. It is retained in the closed position by the pivoted arm q passing through the valve rod h and a wire q'. When the wire q<1> is broken by an arm adjacent the track, the valve moves to open position, but as, owing to the contracted orifice o, the pressure in the piston chamber g<1> falls less rapidly than that in the piston chamber g, the valve closes until equalization of the pressure is restored, when it again opens. The valve therefore opens and closes intermittently until the brakes are fully applied. By means of a pipe p with non-return valve p<1>, the reservoir m is quickly recharged when pressure air is re-admitted to the train-pipe. A locking-device adapted to be tripped by an arm or other means adjacent the track may replace the arm q and wire q<1>. For actuating the regulator lever r to shut off steam from the locomotive, the initial upward movement of the arm q may be arranged to unseat a valve t which admits steam beneath the piston s connected to the lever r. A detent w holds the valve-actuating rod v in the raised position and a pin-and-slot connexion v<2> permits of the subsequent oscillating movement of the arm q. In applying the device to a vacuum system, diaphragm pistons are employed.
