Title: Improvements in and relating to electrical information storage apparatus
Inventor: RINGROSE JOHN WILLIAM
IPC: G11C11/26
Filed: 1955-02-01
Abstract: 789,012. Electric digital-data-storage apparatus. PLESSEY CO., Ltd. May 1, 1956 [Feb. 1, 1955], No. 2955/55. Class 106 (1). An electrical information storage apparatus contains a plurality of storage elements and selection means in the output connections between each of the elements and a common output impedance for selectively reading out information. In Fig. 1 decimal digital data is stored on the dekatron-type counting tubes V1, V2, the zero cathode being indicated at 11. For entering data, clock pulses are supplied to the second guide electrodes 14 from terminal 18 and a number of pulses equal to the digits to be stored are applied to the respective first guide electrodes 13 of V1 and V2 from the respective terminals 19 and 20. Each tube is thereby stepped on from zero to the number to be stored therein. Information is read out by selecting which of the output connections from the zero cathodes is to supply information, the tubes being cycled by applying ten clock pulses to both guide electrodes of V1 and V2, a differentially timed output pulse representative of the digit stored in the tube being read appearing at the terminal 15 across the common output resistor R3 when, the discharge in the tube passes the zero cathode. For reading out from VI, for example, the terminal 17 is maintained at HT - , while the potential of the terminal 16 is suitably raised so that when the discharge in VI is from the zero cathode, the rectifier MR3 will not conduct and the pulse passes to the output terminal 15, whereas when the discharge in V2 is from the zero cathode, a pulse will pass through MR4 and no output appears at 15. An arrangement of tubes in matrix form for storing ten eight-digit numbers which may be selectively read out and which is suitable for use as input and output equipment for the computer referred to in Specification 786,343 is described (Fig. 3, not shown).

Title: Improvements in and relating to aircraft braking mechanism
Inventor: NICHOLL EDWARD JAMES
IPC: B64C25/42
Filed: 1955-03-01
Abstract: 787,470. Aircraft brakes. DOWTY EQUIPMENT Ltd. May 31, 1956 [March 1, 1955], No. 2984/55. Class 103 (1). [Also in Group XXXIII] In an aircraft braking system of the type described in Specification 728,176, it has been found that if too great a pressure is exerted on the friction shoe 17, the force of contact of the wheels with the runway may be reduced to such an extent that it may be difficult to maintain directional control of the aircraft on landing. To avoid this condition the load exerted on the wheels is made to operate, through contraction of the strut 8, 9 and the deflection of torque links 11, 12 and link members 42, 43, a potentiometer 41, shown also in the circuit of Fig. 2. A further similar potentiometer 47 is operated in accordance with the pressure exerted by the pilot on his brake pedal. Thus according to the relation between the load carried by the strut 8, 9 and the pilot's pedal pressure, a contact 63 of a relay B will be moved to make operative either a contact 52 or a contact 56 to supply a relay A. Specification 694,059, [Group XXIX], also is referred to.

A wire-winding machine which is capable of operating either in the Garret systemwith the winding drum rotating -or in the Edenborn systemwith the said drum stationary and the winding arm rotating- is characterized in that a winding disc carrying the winding arm carries two planet pinions, one rolling on a fixed sun-wheel and the other meshing with a sun-wheel fixed or slidingly keyed to the winding drum. A winding disc 8, Fig. 1, carrying a winding, arm, is rotated by a shaft A and carries on a half shaft B, a pinion C meshing with a fixed sun-wheel D and, on a half shaft 19, a pinion 18 meshing with a sun-wheel 20 fixed on a winding drum 15. A clutch 1 is interposed between the two half shafts 19 and B and in one position it connects the two half shafts 19, B so that the pinion 18 rolls on the sun-wheel 20 and the drum 15 is stationary. In the other position the clutch disengages the half shaft B and engages dogs on the winding disc 8 thus preventing the half shaft 19 from rotating. The pinion 18 is then solid with the sun-wheel 20 and the drum 15 is rotated directly by the winding disc 8. In a modification, Fig. 4, a rotating winding disc 5 carries pinions 6, 7 on a common shaft 9, the pinion 7 meshing with a fixed sun-wheel 28 and the pinion 6 with a sun-wheel 4 keyed on a flange 21 of the drum 3. To rotate the drum the sun-wheel 4 is slid by a means 10 to disengage the pinion 6 and engage clutch dogs on the winding disc 5.

IPC: A61H11/02
Filed: 1919-02-13
Abstract: 128,524. Schule, O. Dec. 6, 1918, [Convention date]. Massage. - Adjacent parts of the body are subjected to the action of two flexible bands which oscillate rapidly in opposite directions. The bands are driven by stepped cones on a rock-shaft oscillated by cranks from a continuously-driven shaft of an electro-motor, through an intermediate shaft. The main shaft and the intermediate shaft may be used for working known massage implements, and the motor and gearing are housed in an enclosing casing. The motor shaft 4 drives the intermediate shaft 12 at a reduced speed, and from the latter shaft the shaft 19 carrying stepped cones 20 is rocked through the crank 17. The manner of arranging the massage straps 30, 31 is shown diagrammatically in Fig. 6. They are connected together by links parallel-ruler-wise and are carried by an endless band which can be given different rates of oscillation according to the diameters of the cones employed. Instead of using the crank 17, hypocycloidal spurgearing may be used to oscillate the shaft 19 from the shaft 4. The speed of the massage implements may be controlled by varying the speed of the armature of the motor, e.g. by moving the brushes on the ring 8. Fig. 5 shows an oscillating massaging implement for operating on the throat. It is carried by the cross-head 43 which is coupled to the bar 41, oscillated by the crank 40 from the shaft 36. This is driven by a flexible shaft from the motor shaft or the intermediate shaft.

Abstract: 1373475 Oscillators; pulse detectors INTERNATIONAL BUSINESS MACHINES CORP 24 Jan 1973 [24 Feb 1972] 3609/73 Heading H3T [Also in Division G1] A proximity switching system of the kind depending on the loading of an oscillator-tank circuit, is used to detect missing elements from a train of type passing to a printing machine. Oscillator.-The resonant circuit comprises a capacitor 9 and a ferrite-C-cored inductor 2 having a gap through which the print train 11 passes. The oscillator amplifier comprises an NPN current drive 12 controlled by amplifiers 13, 19. The loop gain of the oscillator is limited by diodes 17, 18. Detector.-The oscillator voltage is sampled at the output of the buffer amplifier 19 by a positive-peak-follower (amp. 26 and diode 27). This output is fed directly to the inverted input of a differential-amplifier 29, and through a delay circuit R32, C30, to the other input of the amplifier 29 whereby a sudden increase in the oscillator voltage due to a missing type element causes the direct signal V1 to rise faster than the delayed signal V2 providing an output from the differential amplifier to stop the machine, e.g. through a "latch circuit" not shown. A similar circuit using individual transistors instead of integrated differential amplifiers is illustrated in Fig. 3 (not shown).
