Title: Combined disc and drum brake
IPC: F16D55/15
Filed: 1955-03-28
Abstract: 767,914. Combined disc and drum brakes. BENDIX AVIATION CORPORATION. March 28, 1955 [June 1, 1954], No. 8987/55. Class 103 (1). A combined disc and drum brake has flat side plates 68 lined with friction material 66 which are pressed into engagement with the inner radial sides of a drum by one pair of ends of levers 76, the levers being pivoted centrally upon fulcrums 85 and closed at their other ends by a fluid pressure piston and cylinder 80, 72. The side plates coact at their non-actuated ends with cam balls 60 which provide a self-energizing characteristic at a result of the drum drag on the side plates. The balls 60 rests internally in recesses in a member 54 mounted in a bushing 56, which passes perpendicularly through the web 38 of a friction shoe 36 pivoted upon a collar 30 fixed to a back or anchor plate 34. Circumferential movement of the plates 68 thus, through balls 60, causes radial pivotal movement of the shoes 36 against the force of torsional retraction springs 50 to engage the linings 64 with the drum. Automatic adjustment mechanism comprising a pin 102 gripped by a spring friction member 92 so as to set the clearance at the play of a pin 108 in opening 106 is provided for the shoes 36. Pairs of oppositely diametrically disposed plates 68 and shoes 36 are shown.

Title: Method and apparatus for observing vocal cord wave
IPC: G10L25/90
Filed: 1964-03-03
Abstract: 1,051,421. Cathode-ray tube displays. HITACHI Ltd. March 3, 1964 [April 3, 1963], No. 9033/64. Heading H4T. Signals (a1, Fig. 2) derived via a microphone A1 (Fig. 1, not shown), held in the region of the trachea and equalized in a circuit A2 (waveform a2) are displayed on the screen of a cathode-ray tube D against a time base which is triggered at a predetermined instant by a pulse (c). The latter is produced by counting in a circuit C a selected number of the pulses of a train (b1) produced in circuit B1 and the timespacing of which is equal to the period of the cycles of waveform (a1). Additionally, a circuit B 2  is employed to convert pulse train (b1) into a pulse train (b2) having amplitude variations corresponding to the variations in timespacing of (b1), i.e. amplitude variations corresponding to variations in pitch (frequency) of waveform (a1) and such variations are also displayed on the tube, e.g. by employing a dual beam tube. The input to circuit B1 may be replaced by the output of a reference generator E producing frequency modulated waves for calibration purposes. The tube preferably has a long persistence to facilitate direct visions.

Title: Improvements in or relating to the de-ironing and reduction of chromium or manganeseores
IPC: C22B34/32
Filed: 1945-04-12
Abstract: A method of de-ironing a chromium or manganese ore, which consists in submitting the ore in a molten state and optionally with an added flux, such as lime, to the action of an alloy of iron and the base metal of the ore, this alloy being rich in the said base metal, thereafter separating the resulting metallic phase from the overlying slag and submitting the latter to the action of a small quantity of the base metal of the ore in a pure state, or a ferro-alloy containing more than 95 per cent of the said metal.  The alloy acting on the raw ore may be that resulting from the last step of a previous identical operation.  The treated ore may be reduced by carbon or by an aluminothermic process for the production of chromium or manganese or of very rich ferro-alloys of these metals, a part of this product being used in the second stage of a further de-ironing operation. Alternatively, the reduction may be performed in two stages, the first stage of which consists in submitting the de-ironed slag, with or without violent intermixing, in the presence of a base such as lime, to the action of an alloy of silicon and the metal to be obtained, this alloy being poor in silicon, one portion of the so obtained metal being used in the second stage of a further de-ironing operation and the remaining slag being submitted, in a second step, to the action of an alloy of silicon and of the metal to be obtained, preferably with violent intermixing, this alloy being rich in silicon and being obtained by the action of quartz and carbon on a part of the de-ironed slag, for instance in an electric furnace, the alloy resulting from this step, being poor in silicon, being used in the first step of a subsequent reduction operation.  Specification 589,125 is referred to.
