Abstract: 230,472. Hasler Akt.-Ges. vorm. Telegraphenwerkstõtte von G. Hasler. March 10, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Automatic exchange systems.-In a system in which a subscriber has access to two exchanges, for example, a private and a public exchange, a single two-conductor trunk connects the subscriber to an intermediate switching point, through which connections to one exchange are made by simply dialling the wanted number. whilst connections to the other exchange are obtained by prefixing a special impulse to the dialled number. In the system shown, the subscriber A is connected by a trunk L<1>, L<2> to the intermediate point AV and thence over back contacts of a relay 2 to the exchange I and calls to the latter exchange are made by dialling the wanted number in the usual way. If, however, connection is desired to a line at the exchange II, a special long impulse sufficient to de-energize the slow-release relay 1 is transmitted by a key TA, the de-energization of relay 1 causing the operation of relay 4 which energizes relay 5 to start up the call-finder AS. Relay 4, which remains energized over resistance W, also connects relay 2 to the test contact so that when this contact is reached by the callfinder, relay 2 energizes to disconnect line L<1>, L<2> from exchange I and connect it over finder AS to the selecting apparatus at the exchange II which is then controlled in known manner. The special impulse may also be produced by depressing the receiver hook or by turning the number dial.

Title: Anti-locking brake control system
IPC: B60T8/72
Filed: 1973-02-09
Abstract: 1410144 Antilock braking systems ROBERT BOSCH GmbH 9 Feb 1973 [12 Feb 1972] 6410/73 Heading F2F [Also in Division H3] In an anti wheel lock control system for fluid pressure operated brakes the wheel retardation is measured by a tachogenerator producng signals which are differentiated at 30 and passed through a low pass filter 34 to two threshold value switches 41, 42, such that when the wheel deceleration exceeds a predetermined threshold b 1  switch 41 passes a signal to the setting input S of a store 45 which causes energization of a solenoid 20 of a pressure regulating valve 13 so that the pressure rear wheel cylinders 14, 15 is relieved into reservoir 17. A monostable multivibrator 35 is provided allowing different responses of the system under different road conditions. On dry roads the wheels are accelerated rapidly and when the acceleration exceeds the threshold value b 2  of switch 42 less than 60 milliseconds for which the output of multivibrator 35 is maintained after response of switch 41 so that the positive outputs of multivibrator 35 and switch 42 actuate AND gate 36 which, through OR gate 37 resets store 45 to de-energize solenoid 20 and reestablish braking pressure. On slippery roads, re-acceleration of the rear wheels requires a period longer than the short period of the output pulse of multivibrator 35, the latter returning to its stable position before threshold value b 2  is exceeded. AND gate 36 thus receives a positive signal only by way of switch 42 and is not operative to actuate OR gate 37. After the threshold value b 2  is passed in a negative direction, switch 42 produces a negative signal inverted at 38 to a positive one which signal resets the store 45. In the above embodiment, the average acceleration of the rear wheels is measured since the tachogenerator 27 is located on a cardan shaft 26 to the differential 25. In a further embodiment, Fig. 4 (not shown), for a front wheel drive vehicle, separate tachogenerators (128), (129) are provided on each wheel the outputs of which pass to resistors (541), (542) the junction between which carries a voltage equal to the average of the tachogenerator voltages. The tachogenerator voltages are also fed to diodes (551), (552) the output of which corresponds to that diode whose anode is at the highest voltage. If one wheel decelerates at a different rate from the other so that the threshold b 1  is not exceeded by the average deceleration rate that diode with the highest anode voltage passes a signal to one input of a comparator amplifier (560) the other input of which is connected through a transistor (540) to the junction of the resistors (541), (542). When the average voltage at this junction is exceeded by the diode voltage by a predetermined amount amplifier (560) produces a negative voltage blocking a transistor (563) whose collector then carries a positive signal which sets the store by way of OR gate (153).

Filed: 1949-03-10
Abstract: 701,371. Endless belt conveyers : loading vehicles. FERREIRA, P. D. F. March 10, 1050 [March 10, 1949], No. 6523/49. Classes 78 (1) and (4) Apparatus for loading filled sacks or the like on to vehicles comprises an endless conveyer, means for attaching the conveyer to the vehicle so that it lies in an inclined attitude leading from the loading platform of the vehicle to the ground, means for driving the conveyer, and a loading platform associated with the conveyer at its lower end. In the embodiment shown. the conveyer belt 8 extends round rollers 2 journalled in bearings 3 adjustably mounted in flanges 4 in a pair of side frame bars 1 which are bent over at one end to form parts 10 by which they are detachably secured to the back of a vehicle. These parts are bridged by a bar 11 formed with a hole 12 adapted to receive a peg 19 upstanding from a web 113 of one of a pair of angle irons 13, 14 which are secured together by a bolt 18, the iron 13 fitting over the loading platform 15 of the vehicle and the iron 14 embracing a spar 16 secured to the platform. A loading platform 21 is pivotally connected to the bars 1 by links 22. Wheels 24 provided with projecting angle irons 25 are secured to extensions of the spindle 23 of the lower roller 2, these wheels being of greater diameter than the roller whereby the belt is supported clear of the ground. Belt guides 26 are secured to the bars 1. When it is desired to pick up sacks deposited by a combine harvester, the vehicle trails the conveyer along and slows down with its platform 21 near a sack. The sack is manipulated on to the platform and tilted over into engagement with the conveyer belt 8 so that as the vehicle moves towards the next sack, the wheels 24 are rotated whereby the laths 27 on the belt lift the sack off the platform. Continued movement of the vehicle results in the belt carrying the sack up to the vehicle platform 15. Angle irons 25 may be disposed on the inner faces of the wheels so as to assist in transferring a sack from the platform 21 to the belt. One or more additional rollers may be associated with the lower end of the conveyer to facilitate this transfer. The flanges 4 supporting the bearings of the rollers 2 may be adjusted by screws 5 so as to vary the tension of the belt 8.
