Abstract: 819,519. Electric motors. GONY, A. L. J. V. March 4, 1958 [April 2, 1957: Nov. 8, 1957], No. 6916/58. Class 35. [Also in Group XIV] The drive pin of a dry shaver is secured to a side of a quadrilateral frame having its opposite sides parallel and is reciprocated by parallel, tilting movement of two of the opposed sides of the frame by an electromagnetic vibrator or an electric motor within the frame. As shown, a drive pin 2 secured to the side 3 of a metal frame is moved in the direction of the arrow F by tilting of the sides 4, 5 as a result of the attraction of an electromagnet 6 for an armature 8 secured to the side 4, the elasticity of the frame causing it to resume its original shape after each pulse. A stop 9 prevents contact between the armature and the magnetic poles and eliminates noise. Multiple cutting heads are operated by a frame having a corresponding number of drive pins and in modifications the distortion of the frame is produced by a cam keyed to one end of a rotated shaft and acting on a tongue projecting from the frame or by an armature staggered with respect to the attracting poles. In a further modification the tilting sides of the frame are formed by blade or U-shape wire springs secured to the other sides of the frame by screws so that the air gap of the vibrator is adjustable.

Patent GB-1367282-A (GB)
Title: Adaptive braking control system
IPC: B60T8/72
Filed: 1973-02-14
Abstract: 1367282 Antiskid braking systems BENDIX CORP 14 Feb 1973 [22 Feb 1972] 7334/73 Heading F2F In an antiskid braking system wheelspeed indicative signals from a sensor 12 are amplified at 16, the amplified pulses being counted by a counter 18 which produces an output waveform, filtered at 20 and differentiated by a derivative amplifier 22 which inverts the signal and passes it to the base of a transistor 26 forming with a transistor 30 a comparator circuit controlling operation of a decay valve driver 44 which operates a solenoid valve 46 of a brake pressure modulator. As the deceleration increases on brake application the voltage output of amplifier 24 and the base bias of transistor 26 increases so that the latter is switched on while transistor 30 is off so that no current flows from a supply line 32 to driver 44. When the bias on the base of transistor 26 equivalent to a deceleration G1 equals that of transistor 30 as determined by resistors 36, 38, 40, transistor 26 turns off and transistor 30 turns on thereby transmitting an actuating signal to valve driver 44 to relieve the braking pressure. The wheel then accelerates past the G1 level until a lower deceleration G2 is attained. When valve driver 44 is actuated, the high voltage output thereof turns on a transistor 56. At the same time a timer mechanism 48 produces an output for a predetermined time so that transistor 52 is turned on. Resistor 38 is thereby connected to ground at 54 so that resistor 40 is switched out of the circuit causing the base bias of transistor 30 to be reduced and to permit a lower base voltage of transistor 26 from amplifier 22 before turning off transistor 30 to suppress the valve driver 44 actuating signal. This lower voltage corresponds to the G2 deceleration level and solenoid valve 46 is turned off when the G2 level is exceeded or timer 48 output signal expires. To suppress spurious signals due to the vehicle passing over certain road surfaces causing a number of decay cycles to be initiated in a short time period a transistor 60 is provided the base of which is initially connected to supply line 32 so that the voltage is at a high level and transistor 60 is switched off. When the wheel accelerates past the G1 level the timer 48 output signal turns on transistor 52 thereby connecting the transistor 60 base to ground 54 through resistor 60. The latter is not turned on since the base thereof is also connected to the output terminal 47 of valve driver 44. If the G2 level is reached, valve driver 44 is turned off, output terminal 47 voltage is grounded and transistor 60 turns on to connect transistor 30 to ground at 66 thereby suppressing all further signals to valve driver 44 to prevent the latter from being actuated until the timer 48 output expires. When this occurs, transistor 52 is switched off, the transistor 60 base bias is raised to turn it off through its supply line 32 connection. Signals will again be transmitted from the transistor 30 to valve driver 44 again permitting decay cycles if wheel deceleration falls below the G1 level.

Title: Improvements in and relating to electric switches
IPC: H01H21/40
Filed: 1925-03-19
Abstract: 253,223. Dodds, J. March 19, 1925. Switches, quick-action. - The quick-action device is mounted on the exterior of the main switch casing and comprises, Figs. 7 and 11, a two-part casing 30, 31 in one part 30 of which is mounted an operating-arm 55 connected to a member 44, and in the other 31 is mounted an elliptical member 32 connected to the switch, and an intermediate bar-member 35 the ends 36 of which engage recesses in the member 32 so that the members 32, 35 always rotate together. The ends 36 are also pressed by a spring 39 into engagement with two of four equidistant slots 59 in the casing, so that normally the member 35 cannot rotate. When the operating-arm 55 is rotated, the member 44 moves with it, and a shoulder 46 on the member 44 engages one end of a spring 42 and moves it towards the other end, which is prevented from moving by a projection 41 on the member 32 till a cam surface 60 on the member 44 presses down the bar 35 against the action of the spring 39 and releases it from engagement with the casing. The spring 42 then causes the members 32, 35 to rotate and the switch to open or close. For this purpose the member 32 is fixed to a shaft 63 which carries a crank 62 which is connected by a link 64, Fig. 1, to crank 22 on a shaft 20, rotation of the shaft 20 actuating cranks 19 and links 18 connected to switch arms 12 pivoted at 9<b>.
