Filed: 1952-01-25
Abstract: 706,453. Agricultural implements. DAIMLERBENZ AKT.-GES. Jan. 25, 1952, No. 2091/52. Class 6 (1) Relates to agricultural implements, such as hoes, adapted to be pushed in front of a tractor and attached to the vehicle by a two-part frame, one part of which is swingable about an axis parallel to the wheel axles of the vehicle and the other part is mounted in the first part and rockable about an axis at right angles to said axles. According to the invention, each frame part is triangular in shape, the rockable frame part having a pivot at its apex and a pivot at its base, and the pivots being engaged in the swingable frame part and associated with means for coupling the frame parts together to permit a sufficient rocking movement on uneven ground. As shown, a tool bar 17, carrying hoes 2, .is shown connected to the front of a tractor 1 by two triangular frames 3, 4 and 5, 6. The base 4 of one frame is swingably mounted in bearings in arms 7 fast with the tractor, and the base 6 of the other frame is fast with the tool bar 17 and carries vertically-adjustable ground wheels 13. The apex pin 8 of the frame 5, 6 is rockable in a longitudinal bearing 10 fast with the base 4 and the tool bar is rockable in a similar longitudinal bearing 11 at the apex of the frame 3, 4 by means of a pin 9 fast with the base 6. A wedge pin 12 secures with play the pin 9 in the bearing 11 and on removal permits detachment of the frame 5, 6 for separate transport. The frame 3, 4 can then be swung back in bearings on the arms 7 for stowing. Power lift of the complete attachment can be effected by a power connection to arms 23. The tool bar 17 has upstanding pins 18 and wedge fastenings 20 for connection to the base tube 6. The connection of the frames to the tractor is preferably some distance above the axles of ground wheels 13 to assist tool penetration and the frame tubes 5 are bowed upwardly where they cross the frame tubes 3.

Title: Communications system and method for transmitting over a limited bandwidth transmission link
IPC: H04B7/08
Filed: 1974-01-17
Abstract: 1449953 Transmission systems MOTOROLA Inc 17 Jan 1974 [20 Feb 1973] 02160/74 Headings H4R H4L and H4M  In a transmission system, particularly for interconnecting a number of mobile subscribers via radio links and a telephone line, the information signals are passed to a line via a notch filter which removes a small frequency band from the total frequency range of the information signals and in this frequency range is transmitted a carrier frequency which is amplitude and frequency modulated with coded squelch signals, indicating the identity of the wanted subscriber, and a signal indicating the strength of the received information signals. As described a number of receivers 10 receive information, e.g. speech, signals and coded squelch signals, e.g. in the band below 300Hz. After detection the speech signals can be reproduced locally or transmitted to a telephone line via a 4KHz Lp filter 17 and a filter 25 which removes a band 2,200 Hz to 2600Hz. The low frequency 'squelch' signals are selected by filter 14 and control the frequency of oscillator 27, having a nominal centre frequency of 2400Hz. In addition the strength of the received signals is detected at 15 to provide a D.C. level signal, proportional to received signal strength, which is fed to a comparator 36 fed on its other input with the output of a ramp generator 37. When the D.C. level from detector 15 equals the voltage from the ramp generator 37 the pulse generator 38 is fired to generate a pulse which resets the ramp generator and triggers the bistable circuit 40. The bistable 40 thus produces a square wave whose frequency depends on signal strength. The square wave is converted to trapezoidal form, to remove harmonics, by shaping network 41 before amplitude modulating the carrier signal from 27 in modulator 30. The amplitude and frequency modulated carrier is added to the speech signal at 26 for transmission to the telephone line 46. At the receiver, Fig. 2, the signal from the line is passed through an a.g.c. unit 51 and the speech signal fed to a reproducer through -a filter 53 which rejects the signalling carrier frequency at 2,400 Hz. The carrier frequency at 2À4KHz is selected by filter 54 amplified and its frequency determined by the limiter 60 and pulse count discriminator 61 to provide the coded squelch signal at output PL. The amplitude modulation of the carrier is detected at 65, and a smooth version produced by average detector 66 is used to provide the control signal for a.g.c. 51 and also as a reference for comparator 71 from which is derived a square wave whose frequency depends on the amplitude modulation in the received carrier signal. By -means of the differentiating circuits 77, 78, pulses are produced at each zero crossing and used to sample and reset a ramp generator to provide a D.C. level signal, indicating the received signal strength at the receiver of Fig. 1, which may be used by a voting comparator to select that one of a number of receivers having the greatest received signal strength.

Title: Electric data translating apparatus
IPC: G06F3/09
Filed: 1958-01-24
Abstract: 871,998. Digital electric calculating apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Jan. 24, 1958 [Jan. 28, 1957], No. 2419/58. Class 106 (1). Data from a computer or first domain, Fig. 1, is fed to a typewriter or second domain via a translating stage which interleaves punctuation marks in accordance with a pre-stored punctuation format. Binary-coded decimal data from the computer is fed parallel by bit and serial by character into a reversible magnetic core shifting register described and claimed in Specification 867,997, which is referred to, with the least significant digit coming first (LF) and is fed out with the most significant digit coming first (MF) via a buffer 37 to a second domain receiving register for controlling the typewriter. In operation data in the reversing register is shifted out MF to the second domain receiving register under control of a shift control circuit which simultaneously also cyclically shifts the pre-stored punctuation format in a punctuation register. When a punctuation mark is to be inserted, this being detected by the shift control circuit, shift of the reversing register is stopped and the punctuation mark passes from the punctuation register via a punctuator (where it is recoded) to the buffer 37 and then to the second domain receiving register. Shift of the reversing register continues until the next punctuation mark has to be inserted. The device can also depunctuate data sent from the second domain to the first, the operation being the reverse of punctuation. Specification 840,050 also is referred to.

Title: Improvements in and relating to switching mechanism for electric discharge lamps
IPC: H05B41/04
Filed: 1943-02-17
Abstract: 562,909. Electric supply. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 17, 1943, No. 2610. Convention date, Feb. 26, 1942. [Class 38 (iv)] [Also in Group XXXVII] A switch is adapted to connect, on manual operation, a discharge lamp with a current supply, and at the same time temporarily to close a circuit through the filaments in series to heat them, and is arranged so that on release of the operating button the series connection is broken, to light the lamp. When more than one lamp is used they may be connected with their filaments in parallel, as shown in Fig. 7, or with all filaments in series, Fig. 8 (not shown). Fig. 6 shows the parts of a switch for effecting the operations. On depressing the button 43, a head 47 bears on a contact disc 36, the underside of the head being so shaped that it coacts with cam surface 37 to allow relative rotation in one direction only. The disc 36 bears arcuate contact bars 39, 40. As it descends a helically twisted strip 31 is caused to rotate as it passes through slot 35, turning a bridging contact 27 to snap over stepped contact surfaces 22 while the bars 39, 40 connect contacts 54, 55 and 56, 57 respectively. As shown in Fig. 7, the closing of these contacts will heat the filaments of the two lamps 60, 61 as long as the button is pressed. On releasing the button, springs 42, 51 cause the disc 36 and plunger 43 to rise, breaking the circuits through the filaments. Since the bridging contact 27 has arms 28 that slip over steps 18 on the base, this contact holds helical strip 31 against turning, thus causing disc 36 to turn as it rises so that bars 39, 40 are no longer opposite their respective contacts 54, 55 and 56, 57. The next depression of plunger 43 will now caupe contact 27 to turn clear of contacts 22, thus switching off the lamp. While bars 39, 40 will, on rising again, rotate into position for restarting the lamps on'a subsequent depression.

Filed: 1968-01-17
Abstract: 1,215,541. Auto changer. V-M CORP. 17 Jan., 1968 [13 Feb., 1967], No. 2644/68. Heading G5R. In an automatic record changer gramophone in which the usual change cycle cam wheel is driven by an electric motor 23 which is energized either automatically by switch 24 at the end of a record or manually by switch 25 to commence play and in which manually operated control keys 27 " off," 28 " auto," 29 " manual " and 30 " cue " are provided, a first latching means is used to hold the switch 25 operated when the " off " key is pressed whereby all the records stored are cycled without being played and a second latching means is provided for holding a cue plate depressed when the " manual " key is operated thereby preventing lowering of the pick-up arm until the latch is released by operation of the " cue " key. Operation of " auto " key 28 or " manual " key 29 depresses bar 44 and energizes the turntable drive motor 17 via switch 20. Latch 52 mounted on an extension 46 of bar 44 acts to maintain the bar depressed and the switch operated after the keys are released until a push off arm 58 is actuated by the auto change mechanism after the last record has been played. In addition operation of either key actuates switch 25 via bar 47 whereby a change cycle is initiated by energization of motor 23. Means, not described, are provided for maintaining energization of the motor after release of the key until the change cycle is completed. On operation of the " off " key bar 47 is depressed to operate switch 25 to initiate a change cycle and by pivoting of latch 64 is held depressed with the switch operated by engagement of the latch hook under a portion 62 of bar 44 in its depressed position. The mechanism then continues cycling without playing a record until the last record is released from the store when the push-off arm releases bar 44 to switch off the turntable drive motor and the upward movement of part 62 of the bar 44 releases the latch 64 whereby bar 47 is released and switch 25 is opened. The cycling process commenced by operation of the " off " key can be halted to continue play by operation of either the " auto " or " manual " keys which release latch 64 by engaging edge 70 thereof. Operation of the " manual " key to play a single record stored on the turntable spindle depresses cue plate 72 and operates latch 82 to hold the plate in its depressed position. The plate compresses spring 96 which in turn moves a collar 74 over a ribbed shaft 73 and pivots an arm 76 which lifts the tone arm 14 and prevents it being lowered during the change cycle after the record has been lowered on to the turntable. Operation of the " cue " key then releases the cue plate and arm 76 is pivoted to lower the pick-up arm on to the record. Movements of the pick-up arm via the cue plate are damped by a viscous material e.g. silicon grease deposited in the grooves of the ribbed shaft 73,

Filed: 1934-01-26
Abstract: 431,156. Actuation of switches. ELLISON, Ltd., G., and ANDERSON, J., Wellhead Lane Works, Perry Barr, Birmingham. Jan. 26, 1934, No. 2716. [Class 38 (v)] Closing mechanism for a circuit-breaker comprises a solenoid a which, on energization, moves a lever m into a position in which it can be actuated by a cam 2 driven by a motor y, switch mechanism for controlling the motor, and means for actuating the said switch mechanism under the control of the solenoid. In the arrangement shown, the plunger b of the solenoid is connected by a link c to a lever d secured to a shaft e. The initial movement of the plunger rocks the shaft e and a lever 9 connected thereto. The upper end of the lever 9 engages a spring-controlled pawl 10 pivoted to a lever secured to a switch shaft 13, and the movement of the lever 9 initiates a switching movement which is completed by spring action and closes the circuit of the motor y and also a maintaining circuit for the solenoid a. On further movement of the plunger b, the lever d engages a lever f connected through levers i, j and l to the lower end of the lever m. This end of the lever carries a roller 22 guided between members 7 and 23 ; by the actuation of the lever f, the roller 22 is moved to the right to bring another roller 3 mounted on the middle portion of the lever m into engagement with the cam 2. The upper end of the lever m is connected by a link n through a spring o to one end of a two-part lever p, q, the part p of which is secured to a shaft r carrying a lever s which, when the cam 2 actuates the lever m, imparts the closing movement to the circuitbreaker. The part q is carried freely on the shaft v carrying the cam 2, the shaft v being driven by the motor through a worm x and worm wheel w. After the circuit-breaker has closed, a projection 21 on the shaft v engages a projection 20 on a lever 19 connected by a link 18 to the switch shaft 13 and moves the latter to the " off " position to reopen the circuit of the solenoid or motor.
