Title: Improvements in and relating to weighing machines
IPC: G01G1/00
Filed: 1936-03-16
Abstract: 472,231. Weighing - apparatus. WHESSOE FOUNDRY & ENGINEERING CO., Ltd., and GREENWAY, E. A. March 16, 1936, No. 7833. [Class 143] Loose-weight apparatus.-In a weighing-apparatus of the type wherein the weighing capacity is varied by the addition or removal of manuallyoperated capacity weights, corresponding adjustment of the indicating. mechanism is effected through gearing which operates a quadrant on a secondary chart, the arrangement being such that operation of the device to increase the weighing capacity first renders a number of equal capacity weights effective in succession, then renders a larger capacity weight operative and the smaller weights inoperative, and then renders the smaller weights operative successively to add their effect to the larger capacity weight. Asshown,the load on the apparatus is transmitted to a rack arm 32 and the indicating pointer, through a lever 9, link 11, lever 12 mounted on a fulcrum 14, rod 25, pendulum lever 26, rod 29 and lever 30. The rack arm 32 carries a stud 70 which normally bears against, and follows, the lever 30 but lags behind if a shock load is applied. The capacity weights 15 .. 21 (in the form of levers fulcrumed coaxially with the lever 12) are actuated by a cam shaft 46 rotated by a hand wheel 56, the cams being arranged to engage the weights directly. In increasing the weighing capacity, rotation of the hand wheel successively raises the smaller capacity weights from the lever 12 to increase the weighing capacity by equal increments. Further rotation of the cam shaft returns the smaller capacity weights and, by means of a countershaft, removes the larger capacity weight 21 thereby increasing the weighing capacity by a further increment, after which the smaller capacity weights are again successively removed up to the maximum capacity. At each addition to the weighing capacity a gear wheel on the cam shaft actuates a gear wheel 63 and a toothed quadrant 64 fixed to a secondary chart 65 exhibiting appropriate major order numerals through windows 66 in the dial. Specification 438,978 is referred to.

Abstract: 662,918. Automatic altitude control systems. BENDIX AVIATION CORPORATION. March 24, 1947 [April 8, 1946], No. 8037/47. Class 38 (iv). In an automatic craft control system an elevator surface is controlled from an electrical pick-off on an artificial horizon gyro to maintain level flight and is also controlled by an electric signal proportional to the movement of an expansible container, sealable on one side from atmosphere, to maintain a predetermined altitude. As shown applied to the pitch channel of an automatic pilot, similar to that described in Specification 662,831, when a desired altitude is reached a switch 57 is closed to close a solenoid-operated valve 54 thereby sealing from atmosphere a casing 51 containing a bellows 50. The interior of the bellows, however, still communicates with atmosphere through a conduit 52 so that in response to changes in atmospheric pressure an energized coil 61 of an inductive device is moved linearly relative to fixed coils 62, 63, connected in opposition, to produce a resultant signal which is injected in series with the pitch and followup signals developed by inductive devices 26, 16 to operate elevator 14 of the craft through motor 13 in such a manner as to maintain constant altitude. In a suitable mechanical arrangement of bellows, inductive device and solenoid operated valve, mounted in a common casing, which is described and illustrated, adjustment is provided for setting coil 61 to a null position when casing 51 is open to atmosphere and a safety valve is provided to open casing 51 to atmosphere upon excessive expansion or contraction of the bellows.

Abstract: 742,490. Centralized dictation systems. DICTAPHONE CORPORATION. March 24, 1953 [April 1, 1952], No. 8055/53. Class 40 (4). A remotely-controlled dictation system generally of the type described in Specification 698,444 is provided with means for producing an intermittent signal to give warning of the approaching end of the record. When the recording head passes a predetermined point, a switch 155 is operated and a multivibrator 182 begins to switch an oscillator 184 on and off, producing brief periodic audible warning signals in the dictator's receiver 16. The recording circuit is broken during production of the signals, each of which lasts 0.1-0.2 sec. When the dictator subsequently hangs up, the attendant is warned to change the record by the flashing of a lamp 136 which normally burns steadily or blinks rapidly when the machine is in use. By means of a switch 62 a dictator may energize a solenoid 72 to make a mark on an indicator slip associated with the record. Actuation of the cradle switch at the dictator's substation operates a solenoid 78 to remove a latch and enable the solenoid 72 to make a longer mark. Reference has been directed by the Comptroller to Specification 698,376.

Title: Improvements in or relating to aircraft sustaining rotors
IPC: B64C27/54
Filed: 1946-03-15
Abstract: 609,551. Rotary-wing aircraft. FAIREY AVIATION CO., Ltd., and BENNETT, J. A. J. March 15, 1946, No. 8157. [Class 4] Provision is made on a rotary wing aircraft by which the rotor blade drag hinges 13 may be locked when the rotor speed is below a predetermined value. The rotor blade arm 25 is pivoted at 13 to a drag link 16 carried on a flapping pivot 19 on the rotor head 23 and carries two lugs 26, 27 adapted to engage a pin 28 on the drag link 16. The blade may be locked in its rearmost position with the lug 27 and pin 28 in engagement by a link 29, pivoted at 30 to the blade arm 25 and at 31 to a plunger 32 in cylinder 33 integral with the drag link 16. A locking lever 36 pivoted to the drag link 16 carries a roller 38 which by bearing against the end 35 of the plunger 32 prevents motion of this plunger and thus prevents the blade arm 25 from moving out of the position in which the lug 27 bears against the pin 28. The locking lever 36 is biassed to this locking position by a spring 40 and is forced therefrom by a link 41 to a spider 43, mounted concentrically of the rotor shaft 22, but free to rotate thereon. The spider 43 is turned from the locked position shown when the rotor speed exceeds a predetermined value by the resulting upward movement of the rotor blade about its flapping hinge 19 which causes a pin 45 on the hinge 19 to bear against an arm 44 of the spider 43. Since all the links 41 controlling the unlocking of the rotor blades are connected to the spider 23, the rotor blades are all released simultaneously. By providing a reversing lever connection between the link 29 and the plunger 32, the rotor blade may be locked in the forward, instead of rearward, position. To lock the rotor when the rotor speed is below the predetermined value, the shaft is accelerated or braked to move the rotor blades to the forward or rearward position, according to which is the locking position. The spider 43 may be replaced by a centrifugal governor actuating the links 41 either directly or through hydraulic servo means.

Abstract: 457,268. Automatic control systems. PORTALS, Ltd., MARSDEN, J. C., and KNAGGS, J., Laverstoke Mills, Whitchurch, Hampshire. March 20, 1935, No. 8755. [Class 38 (iv)] Registration.-In cutting sheets from a web of paper the paper is provided at regular intervals with watermarks which are thinner or thicker than the web and the cutting apparatus is provided with a movable feeler pressing on one side of the web which is supported on the other side as by a transverse roller. Operative connections extend from this feeler to a control device, whereby registration of the cutting is automatically effected. The movements of the feeler cause a succession of electrical impulses which may be used to vary the speed of the web relative to the cutting knives or vice versa, for example by reciprocating a contact member across the path of two contacts on a carrier running at constant speed. A change in the frequency of the impulses will cause engagement with one or other of the latter contacts, and the respective actuation of relays causing a compensating variation in the speed of a motor in the drive for the web or cutting knives or in the circumference of an expanding pulley. The feeler is constituted by a roller 79 which is supported in a cradle giving a magnified movement of a plunger 81. The plunger turns a spindle 83 which may carry a mirror to deflect a beam on to a photo-electric cell 86 or an arm 93 adapted to engage a contact 95. To permit operation with various thicknesses of web the plunger 81 and the elements actuated thereby are mounted on an arm 87 which may be adjusted about a pivot 88. Specification 455,606 also is referred to. The Provisional Specification describes also means for longitudinal and/or lateral registration electrically controlled by a selenium or other light sensitive cell activated by a beam passing through watermarks on the web which may be in the form of crosses. Lateral registration may be effected by axial movement of a guide roll or the feed roll in relation to slitting knives.
