Title: Improvements in brakes for motor vehicles
IPC: B60T13/36
Filed: 1922-09-20
Abstract: 208,250. Royce, F. H., and Rolls-Royce, Ltd. Sept. 20. 1922. Brakes, arrangement and disposition of; hydraulic and pneumatic transmission.-In a vehicle having a fluidpressure brake system the accelerator pedal is connected to the throttle through means depending on the pressure in the brake system, so that when this pressure fails the throttle is no longer acted upon by the pedal and the driver is at once aware of the failure. The driver can then apply the brakes through mechanical means, one pair by a hand lever and the other pair by depression of the brake pedal beyond its normal working position. A pump c driven by the engine supplies air to a reservoir c<1> and through a valve d to two brake cylinders c<2>. Each cylinder applies the brakes on one axle through differential gears g<10 >or h<8>, shafts g or h, and links or cables. The valve d is opened to apply the brakes by means of a pedal e. The accelerator pedal f operates the throttle lever through levers and linkage, one lever f<4> having a fulcrum f<5> which is maintained in position against the action of a spring by air pressure in the brake system acting on a diaphragm enclosed in a chamber f<8> and connected to the fulcrum f<5>. Thus when the air pressure fails the spring moves back the fulcrum and the throttle closes, although the accelerator pedal may be still depressed. The rear brakes can then be applied by means of a hand lever i connected to the brake linkage through a lost-motion device i<5>. The front brakes can also be mechanically applied by the brake pedal e which is connected through a lostmotion connection g<13> to the brake-differential g<10>.

Title: Improved selectivity and fidelity control in high frequency circuits
IPC: H03H7/01
Filed: 1935-09-14
Abstract: 460,787. Impedance networks. COLE, Ltd., E. K., and FALKUS, A. E. Sept. 14, 1935. No. 25547. [Class 40 (iii)] In a band-pass filter, suitable for use in the intermediate-frequency amplifier of a superheterodyne receiver, the coupling is altered simultaneously with the selectivity by the insertion or elimination of resistance. Thus two tuned circuits N1, N2, which have a constant Inductive coupling, have also a capacitive coupling through the condenser C3 when the switches S1, S2 are open. Under these conditions the tuning is broadened by the resistances R1, R2, but the loss of amplitude caused bv these resistances is compensitted by the additional coupling given by the condenser C3. When, however, the switches S1, S2 are closed so as to short-circuit the resistances the tuning is made more selective, but both sides of the condenser require earthed high-frequency potential, so that the coupling- condenser C3 becomes ineffective and the coupling is reduced to that due to mutual inductance of the coils L1, L2. The resistances R1, R2 may be adjustable so that the selectivity and coupling may be continuously variable.

Title: Improvements in or connected with pencil sharpeners
IPC: B43L23/08
Filed: 1933-09-19
Abstract: 411,723. Pencil sharpeners. MOBIUS, T. P., 19, Gerberei, Erlangen, Germany. Sept. 19, 1933, Nos. 25887 and 25888. Convention dates, Oct. 10, 1932 and March 28, 1933. [Class 146 (iii).] Relates to pencil sharpeners of the block type and consists in the provision of means for limiting the advance of the pencil when the point is sufficiently sharpened. In the simplest form a transverse bore is made in the body of the sharpener into which the conical bore opens, the opposite wall acting as a stop for the lead. The transverse bore also acts to permit the discharge of shavings. In the form shown in Fig. 5, a split pin 7 is frictionally mounted in an aperture transverse to the conical opening for the pencil, and the two arms of the pin are cut to different lengths, the shorter one permitting the formation of a sharp point, while the longer one can be moved into position to close the end of the conical bore and cause a blunt point to be produced ; alternatively the pin may screw into the body of the sharpener. In the form shown in Fig. 9, knob 14 is rotatably mounted in the end of the sharpener, and the part 15 is formed with apertures of different depths to cause points of varying degrees of sharpness to be formed. The knob 14 is held in adjusted position by a spring-pressed pin 21 mounted in the body of the sharpener and engaging one of a series of notches in the face of the knob. Indicating marks are provided on the knob.
