Title: Improvements in and relating to speedometers
IPC: G01P1/10
Filed: 1922-04-26
Abstract: 179,169. Hasler Akt.-Ges. vorm. Telegraphen - Werkstõtte von G. Hasler. April 26, 1921, [Convention date]. Counting infractions of speed limit; registering on counters aggregate duration of excessive speed. -An adjustable cam 4 on the speed indicator spindle 1 positions a pivoted member 11 to put in gear clock-driven mechanism for actuating a counter 56 registering the duration of time thespeed limit is exceeded and to engage a pawl clutch on a speed shaft 21 for actuating a counter 31 registering the number of times the limit is passed. The cam 4 has a series of holes equidistant from its axis, and is removably secured by a nut 6, Fig. 3, over the spindle 1, with a pin 3 projecting from a fast disc 2 engaging one of the holes. The pin projects further into a grooved member 5 around which is wound a spring 7 tending to turn the spindle to the zero position. By varying the setting of the cam on the spindle the speed limit may be varied. A disc 24 loose on the speed shaft 21 carries a spring pawl 25 adapted to engage a groove 26 in the shaft. When the speed is normal, the part 11 is held in the position shown in Fig. 1 against the action of a spring 10, with a tappet 46 in the path of a pin 44 on the pawl 25. The pawl is thus held out of engagement with the shaft. When the speed is exceeded the member 11 moves to the position shown in Fig. 2, when another tappet 47 is brought into the path of the pawl pin to disengage the pawl from the groove. A toothed wheel 22 fast with the disc 24 is thus rotated through half a revolution only, and the units wheel of the counter 31 is driven half a step through gearing 28, 29, 30. At the same time a wheel 17 on the member 11, continuously driven from a clockdriven wheel 15, Fig. 2, is brought into gear with a wheel 49, from which motion is communicated to the time-registering counter through worm gearing 50, 51 and a pinion 52 loose on a shaft 20. The shaft 20 is continuously driven by worm gearing from the wheel 15 and operates an hour counting mechanism. When the member 11 returns to normal position upon a reduction of speed, the wheel 22 and counter 31 are driven the further half step to register the single count. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter :-The counter 31 may be driven by ratchet mechanism instead of by toothed gearing, or may be actuated from the time-registering counter; or it may be actuated electromagnetically from a contact on the speed indicator. This subject-matter does not appear in the Specification as accepted.

Patent GB-418381-A (GB)
Title: Azo dyes
IPC: C09B39/00
Filed: 1933-04-24
Abstract: Azo dyes giving yellow or brown shades on leather are obtained by coupling catechin with one or more diazotized amines containing one or more sulphonic, carboxylic or other groups sufficient to render the dyes soluble in water.  Catechin may be coupled with three equivalents of a diazo component, but the preferred dyes are obtained by using two equivalents of a diazo component or one equivalent of each of two different diazo components, preferably selected so that the dyes contain two sulphonic or carboxylic groups or one of each. When o-oxydiazo or o-carboxydiazo compounds are used, the dyes may be converted into complex metallic derivatives by standard methods.  In the examples: (1) catechin is coupled with between two and three equivalents of diazotized metanilic acid, sulphanilic acid, naphthionic acid or picramic acid; (2) diazotized aniline is coupled with catechin and the product is coupled with diazotized 3-amino-5-sulpho-2-hydroxybenzoic acid; diazotized sulphanilic acid may also be used as first component; (3) a disazo dye obtained as in example 2 is boiled with aqueous copper sulphate to yield a copper derivative; (4) the mononitrated diazo oxide from 1-amino-2-naphthol-4-sulphonic acid is coupled with catechin, and the product is coupled with diazotized 2-aminophenol-4-sulphonic acid; the dye yields a copper derivative when boiled with aqueous copper sulphate; (5) diazotized 2-aminophenol-4-sulphonic acid is coupled with catechin and the product is coupled with diazotized 3-amino-5-sulpho-2-hydroxybenzoic acid; the dye yields a chromium derivative when boiled with aqueous chromium fluoride; (6) two equivalents of the diazo oxide from 1-amino-2-naphthol-4-sulphonic acid are coupled with catechin; the dye yields a chromium derivative when boiled with aqueous chromium fluoride; (7) the mononitrated diazo oxide from 1-amino-2-naphthol-4-sulphonic acid is coupled with an equimolecular proportion of catechin; the dye yields a chromium derivative when boiled with aqueous chromium fluoride; (8) the disazo dye of example 4 is coupled with diazotized 3-amino-5-sulpho-2-hydroxybenzoic acid; the product yields a chromium derivative when boiled with aqueous chromium fluoride.

Title: Improvements in or relating to electric motor control systems
IPC: H02P5/68
Filed: 1949-05-09
Abstract: 659,945. Control of D.C. motors. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 9, 1949, No. 12325. Convention date, May 21, 1948. [Class 38(iii)] A control system for a plurality of electric motors having series field windings comprises a plurality of acceleration controllers for controlling the motor current, a reversible pilot motor for driving said acceleration controllers in unison, switches co-operating with said acceleration controllers to connect the motors first in series-circuit relation and then in parallelcircuit relation, and additional switches co-operating with said acceleration controllers to establish dynamic braking connections for the motors, said acceleration controllers during both series-circuit and parallel-circuit operation being operated by the pilot motor in one direction during acceleration and in the opposite direction during dynamic braking. Traction motors TM1. TM2, are connected in series when switches LS1, G, S1-S4 are closed, the motors being accelerated when a reversible pilot motor PM drives rollers 31, 32 and 41, 42 towards the left from the position shown, so removing portions of sectionalised resistors 33, 34 and 43, 44. The resistor-sections are connected to contact-fingers which are forced against bus-bars when engaged by the rollers. When the rollers reach the sixth positions (shown dotted), switches LS2 and J are closed to establish a transition bridge circuit for the motors; switches S1-S4 are then opened and switches P1-P4 closed, the transition from series to parallel connection of the motors being completed when switch J is opened. During parallel operation the rollers are moved leftwards from the seventh to the tenth, end, positions, controllers F1, F2 then being actuated to shunt the series field windings of the motor step-by-step until maximum speed is reached. Coasting is provided by opening switches LS1, G, LS2, P1-P4, the controllers F1, F2 remaining in the position providing minimum field excitation. Switches B, B1-B4 are closed to establish dynamic braking connections, but since the motors have minimum field excitation and the total armature resistance is included, only a small braking-current is developed during coasting. The braking connections are such that field windings 14, 13 are respectively placed across armatures 11, 12, thereby reversing the armature currents and causing the motors to act as generators. The braking-effort is increased by increasing the field excitation and then moving the rollers from the tenth to the first positions, thereby removing resistors 33, 34, 43, 44. The operation of the rollers may be automaticaJly controlled by current-responsive relays. The controllers F1, F2 may be operated by an air engine.
