Title: Improvements relating to vehicle brake adjusting mechanism
IPC: F16D65/56
Filed: 1947-02-07
Abstract: 620,995. Adjusting brake shoes. FODENS, Ltd., FODEN, W., and TWEMLOW, E. Feb. 7, 1947, No. 3698. [Class 103 (i)] In automatic shoe-adjusting means for brakes of the two leading-shoe type, wherein a brake shoe is coupled to an oscillatory frame carrying a pawl so that if in a brake application the shoe movement is sufficient, the pawl during release turns a ratchet-wheel to effect an adjustment, further adjustment is prevented when the friction linings have worn down to a predetermined extent, by a' stop which limits the movement of the pawl frame. The brake shown comprises primary and secondary shoes a, c operated by a cam b, the shoe c through a lever d engaging the shoe at c. The shoe c anchors at the one end or the other 7, 10 on a fixed abutment 8 or on a lug 9 on the lever d according to the direction of rotation of the drum. The part 8 serves also as an abutment for the cam b. The lever d by the eye f, Fig. 3, and the shoe a by the abutment piece o thereon have pivotal connection respectively with sleeves g, n engaging oppositely threaded parts h, m of a shaft driven through worm gearing i, z by a shaft g. A frame s mounted on the shaft y is connected by a rod q to the shoe c and carries a pawl w engaging a ratchet-wheel x coupled to the shaft y. Thus, if in an application of the brake, the movement of the shoe c is sufficient, the pawl slips a tooth and during the return movement operates the sleeves g, n to adjust the shoes. When, however, the lining of the shoe c has worn down the permissible extent, the frame s engages a stop 4 provided on the fixed housing k, thus preventing further adjustment of the shoes, continued application movement of the shoe c being permitted by sliding of the rod q in the pin r on the frame s against the action of a spring t on the rod. Return movement of the frame s is effected by a collar v on the rod. The ratchet-wheel x is coupled to the shaft y by a yielding clutch device 2 as and for the purpose described in Specification 620,994.

Title: Improvements in or relating to electrical oscillators
IPC: H03C3/30
Filed: 1946-02-06
Abstract: 624,692. Automatic control systems for oscillators. PHILCO RADIO & TELEVISION CORPORATION. Feb. 6, 1946, No. 3710. Convention date, Aug. 31, 1944. [Class 38 (iv)] An oscillator to be stabilized in frequency is given a small periodic frequency variation, and its output is fed to a tuned circuit whose rectified output is applied to correct the frequency of the oscillator. The oscillations from a velocity modulated oscillator 11, Fig. 1, are applied to a resonant cavity 31 whose output is rectified at 33 and applied over amplifiers 45, 51 to series connected diodes 58, 59. A multi-vibrator 35, 36 applies a pulse at high audio-frequency to the repelling electrode 15 of oscillator 11 to produce periodic variations in frequency. If the cavity has a characteristic 34, Fig. 2, and the oscillator 11 is producing a frequency fl, the pulse 64 applied to the repeller 15 produces a change of frequency causing a variation of amplitude corresponding to a negative pulse 65 to appear at 33 ; if the oscillator is producing frequency f2, the pulse 66 from the multi-vibrator produces a variation of amplitude corresponding to a positive pulse 67 at 33 ; while if the frequency of oscillator 11 is at fo, the pulse from multi-vibrator 35, 36 produces a variation of amplitude corresponding to a negligible pulse at 33. The series diodes 58, 59 pass the pulses to appropriate charge condenser 63 to vary the impedance of valve 24 and thus the potential of tapping 21 determining the potential of repeller 15, and thus maintaining the frequency of oscillator 11 at the resonant frequency of the cavity 31.

Abstract: 243,204. Culemeyer, J., and Hannoversche Waggonfabrik Akt.-Ges. Feb. 11, 1925. Hopper wagons; doors, wagon.- Relates to self-discharging vehicles, particularly those also adapted for conversion into flat-bottomed vehicles, of the kind in which the hopper opening is closed by means of a pivoted door or trap h rotatable about either of two axes i so as to discharge the contents to the left or right as desired. According to the invention, the axes i are not situated at the side edges of the door, but are disposed at some distance inwardly thereof, so that, when one end of the door is lowered, the other end moves upwardly to effect a loosening or displacement of the goods carried. In the construction shown in Fig. 1, the door is operated by means of two chains k passing over pulleys m to winding-gear n, o and, during the movement of the door, one set of pivot pins i moves in arcuate slots p having their centres at the other set of pins. In order to allow the door to fall past its normal side discharge position II to a substantially vertical position III, one of the slots p is open at the bottom, while the other has a continuation s struck about a pulley m as centre, so that the door may pivot from position II to position III about the axis m. If desired, both slots p may be open at the lower end and provided with a continuation s. In a modification the pins i are carried by pivoted links bearing at their upper forked ends aganst fixed pins disposed near the bottom side edges of the hopper. The door h is preferably given a concave curvature upwardly, thereby giving an increased angle of glide to the goods at the commencement of their discharge. The vehicle can be converted to a flat-bottom vehicle by the usual hinged 'bottom-flaps b and pivoted end-doors d, Fig. 2. The latter are provided with sliding extensions g or are hinged in guide-slots a,t their upper ends so as to compensate for the smaller length required when they are moved to the vertical position. The wheel axles ware preferably located as near the ends of the body as possible and the sides made as high as possible.

Drawings to Specification. [Classes 39 (i) and 40 (iii)] For colour-television or the like, a cathoderay tube comprises a screen provided with a plurality of series of streaks, each series consisting of two or more adjacent and parallel streaks of materials fluorescing in different colours, and the electron beam is deflected to move longitudinally of the streaks to produce traversal of a scanning strip and to move laterally of the streaks to excite a particular colour. The width of each streak is one-third that of the scanning strip and is equal to the width of the fluorescent spot. A photo-electric cell giving progressively greater electrical response from the blue to the red end of the spectrum may be used at the transmitter. Further, the fluorescent spot may traverse portions of two streaks to give a mixed colour. In another form, the width of the fluorescent spot may be the same as that of the scanning strip and the electron beam is varied in intensity across its width by means of a divided control electrode to produce the requisite colours. In a further form, the spot is adapted to move at right angles to the streaks to form the scanning strip, and hovers over those streaks which are to be excited and passes more rapidly over the others. The intensity control of the beam may be effected in the neighbourhood of the cathode and the coloursensitive control may be effected by the normal deflecting plates. The screen may be provided with fluorescent streaks arranged adjacent streaks which do not fluoresce as stated in Specification 425,267. In another form, the screen is adapted to produce white light and is associated with colour filters arranged in striplike formation perpendicular or parallel to the scanning strips.
