Abstract: 860,290. Electro-forming articles. PLATECRAFT OF AMERICA Inc. May 7, 1958 [July 19, 1957], No. 14588/58. Class 41. An article is produced by electro-deposition by forming a master, applying a coating over the master by simultaneously electro-depositing metal and settling additive particles on to the surface of the master while causing relative movement between the master and the electroplating bath, and thereafter removing the master. The relative movement may be brought about by rotating the master in the bath. The additives may be water-insoluble inorganic salts, metallic oxides, carbides or carbonates, abrasives or finely-divided metal. After applying the coating the master may be electrolytically provided with a further metal coating to provide a stress-free layer around the first coating. The master may be removed mechanically or by chemical attack. Specification 860,291 is referred to.

Title: Improvements relating to the measurement of magnetic field strength by the use of a material exhibiting the "hall" effect
IPC: G01R33/07
Filed: 1949-06-01
Abstract: 659,653. Measuring magnetic intensity. BRITISH THOMSON-HOUSTON CO., Ltd., and HIBBERD, R. G. June 1, 1949, No. 14727. [Class 37] The intensity of a magnetic field is measured by apparatus utilizing the Hall effect. According to the invention, current from V1 is applied at A to a plate P exhibiting the Hall effect, and traverses two parallel paths each including resistance R5, R4, a meter M being connected between the output points XY which are normally at equal potential. A potentiometer R6 enables the points XY to be initially adjusted to equal potential. The two paths AX, AY and the resistances R4, R5, R6 thus form a balanced bridge; any variation of magnetic field at right angles to the plane AXY unbalances the bridge, and the unbalance current is a measure of the variation.

May 22, 1931, No. 15179. Convention date, May 28, 1930: [Class 100 (ii).] Tripping-arrangements.-In a time-recording or other printing device having a solenoidoperated platen the circuit of which is closed by the insertion of the sheet &c., a trigger is provided which holds apart the contacts of the solenoid circuit and is tripped by the insertion of the sheet, to effect the printing stroke, and then rendered inoperative by the presence of the sheet to avoid unintentional repetition of the impression. The platen 17 is carried by a plunger 18 actuated by a solenoid 19, the circuit of which is completed by contacts 21, 22 drawn together by a spring 28. The contact 21 is carried upon an arm 25 pivoted at 27 and having an aperture 36. The arm 26 is normally held so that contact is broken by a trigger 29, pivoted at 31 and drawn towards the position shown in Fig. 3 by a spring 32. The sheet 34 when inserted on the platen displaces the trigger and allows it to pass through the aperture 36, so that the arm 26 falls, as shown in Fig. 2, contact is made, and the solenoid energized. The upward stroke of the platen disengages the trigger and allows it to return to its normal position, as shown in Fig. 3, and the circuit is also broken so that the platen falls. The sheet is now held between the trigger 29 and the arm 26 and the printing operation cannot be repeated since forward movement of the sheet would cover the aperture 36, and retraction of the sheet leaves the trigger in its normal position.

Title: Improvements in and relating to dynamic braking systems
Inventor: SIMONS DAVID SPENCER
IPC: B66B1/12
Filed: 1955-05-26
Abstract: 802,737. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. May 28, 1956 [May 26, 1955], No. 15255/55. Class 38 (3). When an induction motor is operating at full speed its rotor resistance controller is permitted to move at a high rate until it reaches a point providing a slightly higher value of rotor resistance than that affording maximum dynamic braking torque, this point corresponding with position A on potentiometer 6. Accordingly, a contact member 5, which is mechanically coupled to the control member for the rotor resistance, moves at a high rate to the point A. A further reduction in the value of the rotor resistance at this rate would lead to unstable braking operation, so that, when the contact 5 reaches the point B, a relay 3 is energized and contacts 31 close to make the circuit of relay 311 for reducing the rate of change of resistance in the rotor circuit. The relay 3 is subjected to the difference of voltages derived respectively from the potentiometer 6 and a tachometer generator 1, which is driven by the induction motor and is connected to rectifier 2. The relay becomes energized when the speed-responsive voltage exceeds the voltage related to the position of the rotor controller. If the induction motor is running at a speed lower than full speed; the tachometer voltage is less and the change to a lower rate of rotor resistance decrease occurs later than in the conditions just described. In another arrangement, a tachometer generator 1, driven by the induction motor, is connected to voltage-sensitive relays 11, 12, which close their contacts when the tachometer speed exceeds 60 per cent and 30 per cent of full speed, respectively. Conductive strips 14, 15 and 16 are mechanically coupled to the moving element of the rotor resistance and are arranged to close contacts 17, 18 and 19 in succession. If the induction motor is operating at a speed above 60 per cent of full speed, then contacts 11<SP>1</SP>, 12<SP>1</SP>, are closed and relay 13 is energized to reduce the rate of removal of rotor resistance when strip 14 closes contacts 17, the rotor resistance still being at a high value. If the motor is operating at 30-60 per cent of full speed, contact 12<SP>1</SP> only is closed so that the change in rate occurs when strip 15 closes contacts 18. When the induction motor is operating at a low speed, the relay 13 is not energized until strip 16 closes contacts 19.

Abstract: 735,571. Helicopters. HILLER HELICOPTERS. June 18, 1952 [June 25, 1951], No. 15364/52. Class 4, In a control mechanism for helicopters similar to that described in Specification 662,319 increase of pitch of the blades of a pilot actuated control rotor results in consequent flapping of that rotor and associated pitch change of the blades of a lifting rotor, the two rotors being mounted on a central hub in a common plane, so that when the lifting rotor flaps as a result of such pitch change a feed back linkage between the two rotors decreases the pitch of the control blades which in turn limits excessive flapping movement of the lifting rotor. In Specification 662,319 the feed-back linkage results from an offset between the pitch changing and flapping axes of the two rotors whereas in the present invention the axes lie in a common plane and in consequence each feed back linkage comprises an arm 106 pivotally mounted at its inner end 107 on a hub member 76 in which both lifting rotor blades 2 and control rotor blades 3 are pivotally mounted in a common plane for pitch changing movements. The outer end of arm 106 is connected by a ball joint 111 to the lower end of an arm 112 pivotally mounted at 113 on the shaft 72 of the control blade 3. Intermediate its ends, and preferably at its mid point, the arm 106 is connected by a universal joint 104 to one end of a scissors linkage 97, the other end 99 of which is pivotally mounted on the rotatable element 58 of a swash plate actuated by a pilotcontrolled arm 54. Ultimate flapping motion of blade 2 in the direction of arrow A, Fig. 2, as the result of pitch changing motion imparted to the control blade 3 will cause the joint 107 to move in the direction of arrow B and the joint 111 to move in the direction of arrow C thus causing pitch adjustment of the shaft 72 as indicated by arrow C<SP>1</SP> to cancel out some of the cyclic pitch initially imparted to the control blades by the swash plate mechanism. The input leverage X/Y of the linkwork is preferably 2¢ to 1 and the feed-back ratio D/L is preferably 1. Specifications 645,234, 713,358 and 735,572 also are referred to.
