Abstract: 622,689. Hydraulic brakes. DUNLOP RUBBER CO., Ltd., and TREVASKIS, H. W. Nov. 19, 1946, No. 34193. [Class 103 (i)] In a hydraulic master cylinder suitable for operating aircraft wheel brakes, the piston is formed with an axial bore through which the liquid is supplied to the brakes and the valve which opens the pressure chamber to the reservoir has a stem which is slidable in the bore and is opened by engagement with the piston. The piston may be stationary. As shown, a cylinder 3, formed with a reservoir 2, is slidable on a fixed hollow piston 9 connected to the brakes by passages 10, 26. The cylinder is returned by a spring 21 enclosed in a  casing 7. The stem 14 of a valve 18 extends through the cylinder wall 4 and carries an apertured disc 17 and a screwthreaded sleeve 19 which can be locked in adjusted position on the stem by a pin 20. Normally the disc 17 engages a collar 13 and the sleeve 19 engages the wall 4 so that the valve is held open to an extent determined by the adjustment of the sleeve. When the cylinder is moved downwards to apply the brake, the valve is closed by the spring 22. The piston may be movable instead of the cylinder. An end cover fitted with a removable filling-plug and an unspillable vent 24 is shown. When an aircraft is to be steered on the ground by differential braking, two master cylinders, one for each wheel brake, may be mounted on the rudder bar.

[Class 44] A lock of the kind operated by means of a key 1, Figs. 1, 2, having a number of adjustable pins 2 which enter bores in the lock to actuate sliding tumblers 7, comprises a casing, a bolt 21 sliding therein, a frame rotatably mounted in the casing about an axis at right angles to the bolt and provided with bores housing the spring tumblers 7, each connected to a rotatable disc, e.g. by rack 11 and pinion 12, the discs having notches 14 which are brought into alignment when the key is inserted so as to allow a fence 15 to engage therein. The frame, tumblers, discs and fence form a rotatable unit, and co-operating means on the unit, e.g. a latch 19 and a slot in the bolt 21 cause the latter to be moved when the unit is rotated by the key. A push-button 22 acting on a leg of the latch 19 allows the fence 15 to be disengaged from the notches 14 and the lock to be latched again. In the form shown diagrammatically in Fig. 4, the fence 15 is stationary with regard to the frame and rotates therewith, while the unit consisting of the plate 9, sleeves 8, tumblers 7 and discs 10 (the latter being connected to the tumblers by links 61) can slide rearwardly relatively to the fence wnen the notches 14 are aligned, so that a pinion, 62 engages a toothed ring or rack 63 to actuate the bolt. In the elaborated form, Fig. 5, the links 61 are pivoted to hubs on which the discs fit sufficiently tightly to ensure rotation by the hubs, but permit relative rotation when required to change the key setting. The fence 15 is carried by a drum 32 having external teeth engaging a rack on the bolt 21. The tumblers, links, discs and shaft 26 are carried in a sliding casing 42 which is urged towards the key-hole end of the lock by a spring 46, but can be held in each end position by a latch 67 operated by a lever 67<SP>1</SP>. In the forward position, the lock is inoperable by the key, while in the position in which the discs engage the fence, the setting of the lock may be changed by first adjusting the key pins and inserting the key so as to rotate the hubs independently of the discs. An internal knob 40 permits the bolt to be moved by direct operation of the drum 32. A keeper plate 44 is preferably provided to retain the plate while turning. In the form shown in Fig. 8, the tumblers 7 are housed in a barrel 9 and are formed with racks 11 which engage pinions 12, each pinion being coupled to a disc freely mounted on a common shaft 26 by a spider 25 fast to the pinion and having spring arms with projections which engage in depressions 27 in the discs, thus permitting re-setting. Notches 14 on the discs are brought into alignment with one another and with a groove 29. in barrel 9, and on backward movement of the barrel a tongue 34 on a rotatable member 32 enters notches 14 and groove 29. The rotatable member 34 is formed with teeth 35 which engage a rack on the bolt 21.

Abstract: 1473730 Digital data transmission COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE CII HONEYWELL BULL 9 Aug 1974 [3 Sept 1973] 35246/74 Heading G4A In data transmission between a computer 1 (Fig. 7) and a peripheral 2, in which a first signal represents the address at which data is to be read from or written into and a second signal represents the data, both signals are checked for errors. As described the computer and peripheral are connected by two circuits 3, 4. Initially circuit 3 sends a signal ENO and CSO to circuit 4, signal CSO being an outward check signal which results in circuit 4 sending an inward check signal CSI to unit 3. After validation of address data on line DP gate 5 is enabled and first the signal CSO and then a signal CSI lapse. To transfer data to the peripheral, circuit 3 sends a signal DSO which results in a return signal DSI at which signal DSO lapses and the data being transmitted is validated after which signal DSI lapses. This recults in signal ENI being generated which allows signal ENO to lapse. To read-out data to the computer when the signal CSI lapses, signal ENI is generated which makes a signal ENO lapse generating signal DSI. This results in signal DSO being generated, signal DSI then lapsing to validate gate 5 so that the data is checked after which signal DSO lapses causing signal ENI to lapse. If an error is detected in the address or data an error signal EV3 and signal ENI are generated, the latter starting a sequence of signals which results in signal ENO being allowed to lapse and then regenerated to start a new cycle.

Title: Methods of using magnetic digital data recorders
IPC: G11B20/14
Filed: 1976-08-31
Abstract: 1513484 Digital data retrieval INTERNATIONAL BUSINESS MACHINES CORP 31 Aug 1976 [24 Nov 1975] 36047/76 Heading G4C  In a magnetic digital data recorder, the readback signal is phase-adjusted to correspond with the phase of a reference signal. The readback signal passes via an adjustable phase equalizer 14 to a clock generator, detector and digitizer 15, the reference signal being a clock signal generated by a phase-locked loop within the unit 15. Phase errors between the readback signal and the reference signal are counted at 23 and, when a predetermined count N has been reached, a sequencer 33 is actuated to interchange the integration of a pair of alternate integrators 41, 42 and to cause a controller 44 to adjust a counter 34 which in turn controls the phase adjustment made in unit 14. Integrators 41, 42 alternately integrate the phase errors over N cycles of the readback signal, the completion of an integration cycle by one causing the other to be squelched and to begin its integration cycle. A comparator 42C compares the current total phase error with that for the previous cycle, and actuates the controller 44 accordingly. The arrangement is such that if the sign of the current total phase error is the same as that of the previous total phase error, the direction of counting of the counter 34 is reversed; if not, the direction of counting of the counter 34 remains unchanged. Moreover, the direction of counting of the counter 34 remains unchanged or not according as the size of the current total phase error is less than or greater than the size of the previous total phase error. This causes the phase adjustments made in unit 14 to zero in on zero phase error.
