Title: Means for facilitating changing speed
IPC: F16H61/02
Filed: 1929-03-01
Abstract: 326,335. Lush, G. W. M. March 1, 1929. Facilitating changing speed. - The driving and driven shafts C, D of a main changespeed gear A are connected by flexible shafts S<1>, S<2> to shafts l,m in an auxiliary gear box E, whioh has a differential for each speed, the cage element k of which differential is at rest when the corresponding speed is operative, or when the gears for that speed are in condition for engagement without shock. A separate centrifugal governor t, Fig. 3, is associated with each differential and mechanical means are provided to prevent gear-control lever G from being moved to bring in a speed unless the cage k corresponding is at rest. Normally lever G cannot be moved into slots 1, 2, 3 in the gate because a sliding block x upon it is obstructed by levers V', V<2>, V<3>, which are pivoted upon a plate w. These levers V<1> &c. are prevented from moving out of the way by trigger-levers u<1>, u<2>, u<3>. which, as shown in Fig. 4, project above plate w and are adapted to be operated by the sliding parts r of the governors t. When, say, the second speed can be engaged without shock, the cage k and governor t corresponding stop, and trigger lever u<2> is withdrawn below the plate w. Stop lever V<2> is then free to move out of the way when control lever G is moved into gate slot 2. To move lever G into reverse slot R, block x is raised by hand out of the way of a fixed stop r. In changing down from third or highest to second speed, a lug x<1> on block x engages a trip lever z<2>, Fig. 3, which pulls a Bowden wire B so as to accelerate the engine. When the first or lowest speed is put into action, a link y extending from lever V<1> engages a trip lever z<1>, which also pulls wire B.

Title: Adjusting or regulating arrangement for negative electric resistances
IPC: H03B7/00
Filed: 1935-03-04
Abstract: 443,664. Telephonic amplifiers. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. March 4, 1935, No. 6772. Convention date, March 2, 1934. [Class 40 (iv)] [See also Group XL] The transmission gain afforded by a negative resistance device is regulated or adjusted by connecting the device between the source and the output and by shunting it by a resistance or impedance, permeable to alternating current and preferably variable. The negative resistance 5, connected in series between the source 1, 2 and the output 3, 4, is shunted by a variable resistance 6 in series with a blocking condenser 8. The working-point on the characteristic of the device 5 is determined by a battery 7 from which the signal current is diverted by a choke 9. The resistance 6 may be supplemented or replaced by an inductance coil, a condenser, or a resonance circuit; and the resistance 6 may be connected across the terminals 1, 2 or 3, 4. The negative resistance 5 may be inductively associated with the circuit connecting the terminals 1, 3 or 2, 4. The variable resistance 6 may be adjusted by remotely controlled step-by-step switches, or may be self-adjusting in dependence on any given factor. A gridcontrolled valve may be used as the variable resistance. When a variable inductance is employed, its value may be adjusted by varying a saturating current. By continuous variation of the resistance 6 by means of a modulating current, a carrier applied at 1, 2 may be modulated. If the negative resistance 5 produces frequency distortion, this may be corrected by suitable choice of the shunting impedance.
