Abstract: 1,074,091. Gyro-magnetic resonance apparatus. NEWPORT INSTRUMENTS Ltd. Jan. 10, 1964 [Jan. 11, 1963], No. 1400/63. Heading G1N. [Also in Division H3] The phase angle between a cyclically recurrent phenomena such as the moments (a, b, a in Fig. 1 not shown) of resonance absorption of power in nuclear magnetic resonance or electron spin resonance, and the cyclic variation of the means inducing the phenomena (e.g. an alternating magnetic field H em  superimposed on a slowly linearly varying direct field H m ) is indicated by the average output of a bi-stable arrangement switched from one stable state to the other by pulses derived from the cyclically recurrent phenomena (a, b, a) and passed through two gating circuits controlled by the inducing means so that pulses occurring in positive half cycles of the inducing means (wave Hem) switch the bi-stable arrangement in one direction and pulses occurring in negative half cycles switch it in the other direction. In the Fig. 2 inputs E and D to the bistable circuit B are derived from gating circuits G1, G2. Antiphase reference signals Ref. 1, Ref. 2 derived from the waveform H cm  and at approximately 90‹ thereto, are fed over switches T 1 , T 2  to open the respective gate G1, G2 when the corresponding reference voltage is positive, or, alternatively, when its reference voltage exceeds a certain positive value shown by the broken line. Pulses representing the resonance times (a, b, a) are passed by gates G1, G2 depending on whether they occur while the amplitude of waveform H cm  is increasing or decreasing. The bi-stable circuit output A thus oscillates between two valves and the average output appearing across capacitor C will be a measure of the ratio of the periods during which the bi-stable circuit is in each state, and hence a measure of the phase of the pulses (a, b, a) relative to the waveform H cm . In an alternative arrangement the separate functions of switching, gating and bi-stable circuit operation may be combined in a single circuit controlled by a single reference waveform.

Abstract: 1389761 Vehicle container lifting and tipping mechanism MASCHINENFABRIK FAHR AG 11 Jan 1973 [28 Jan 1972] 1452/73 Heading B8E A trailer for lifting and tipping a container 6 comprises a lift arm 4 pivotally connected between the vehicle U-shaped frame and upper beams 5 which engage the container. Lifting is effected by rams 12 under the control of a guide rod 7 in two pivotally connected parts 8, 9. A telescopic strut 13 connects the forward ends of the beams 5 to the vehicle frame and comprises interengaging tubular members 14, 15, Fig. 4, the former having a pawl 16 which engages with studs 17, 38 of the latter. An arresting device 27, Fig. 5, is provided at the free end of rod part 9 comprising a pivoted pawl 29 and a pawl 31 connected by a spring 32 thereto. Extension of the rams 12 wiil initially raise the beams 5 to engage and lift the container 6 while held level by the guide rod 7 which cannot contract since the end of the part 9 is engaged by the stop pawl 29 until the stud 17 enters the notch 20 of the pawl 16 and extension of the rams 12 is stopped. When the rams 12 are stopped the beams 5 will fall slightly under the weight of the container 6 causing the stud 17 to move along a slot 21 and by a Bowden cable withdraw a catch 37 from the stop pawl 29. At the same time a pull is exerted on the part 9 causing a stop 30 to engage pawl 31 pivoting it and through the spring 32 moving the pawl 29 to the inoperative position. Further extension of the rams 12 now causes the beams 5 to pivot to tip the container 6 since the guide rod 7 can now move into the arresting device 27. After tipping as the beams 5 lower the rod 7 contracts so that a collar 33 restores the pawls 31, 29 so that the latter is again in the arresting position when the end of the part 9 has passed it. In a modified construction, Figs. 7, 9, a guide rod 38 is pivoted at 40 to a guidepiece 39 in a groove 41 of which a roller 42 attached to the lift arm 4 runs. A catch 52 stops movement of the rod 38 unless it is retracted by a Bowden cable 45 actuated through a diaphragm pump 44 when a stud 49 acts through an arresting device 43 on the pump 44 to allow tipping after a small fall of the arms 5 as in the previous example.

Title: Device for the protection against overcharging of the control chamber of the release valve of a brake control valve
IPC: B60T15/54
Filed: 1931-01-19
Abstract: 356,626. Fluid - pressure brakes. HARDY MASCHINENFABRIK UND GIESSEREI AKT.-GES., GEB., 46, Praterstrasse, Vienna. Jan. 19, 1931, No. 1774. Convention date, Feb. 6, 1930. [Class 103 (i).] In a device for preventing overcharging of the control chamber of a compressed air brake-release valve, the valve through which the control chamber is charged from the auxiliary reservoir is maintained open by a control element when a predetermined maximum pressure is exceeded until the pressure has again fallen below this maximum. The control chamber connected to a duct 7 is charged from the auxiliary reservoir connected to a duct 6 past a valve 9 which can rise independently of a spindle 12 connected to a spring-pressed diaphragm 5. When the pressure in the auxiliary reservoir, and hence also in the control chamber, rises above the normal operating pressure to which the spring 15 acting in the diaphragm 5 is adjusted, the diaphragm 5 and the valve 9 are raised. Air flows from the control chamber into the auxiliary reservoir when the pressure in this latter falls due for instance to a brake application, until the normal operating pressure is attained when the valve 9 is reclosed. The downward movement of the diaphragm is limited by a disc 14 attached to it and engaging a shoulder on the valve casing. The spring 15 is adjusted by a screwed nut 16. The brakes may be released by the operation of a handle 21 which raises a valve 18 and the valve 9 by an extension 19 of the valve 18, thus connecting the control chamber and the auxiliary reservoir to atmosphere.

The feed bars 1, 1<SP>1</SP> are moved along rectangular paths by conventional means and the crank operation of the press fed by the device is also conventional. Links 8, 8<SP>1</SP> connect a plate 4 extending below the bars 1, 1<SP>1</SP> to a member 9 on a rod 11 normally rigid with a sleeve 12. A pinion holder 14 pivoted to the sleeve supports a pinion 16 which runs on a rack 17 fixed to the press frame and engages a rack 18 movable in a groove in the frame and carrying a pair of pushers 20. The links 8, 8<SP>1</SP> are connected by pins 7, 7<SP>1</SP> to blocks 6, 61 which run in slots 5, 5<SP>1</SP> in the bar 4. When the bars are moved, during crank rotation through 120 degrees, through the advance stroke, the assembly of parts 5-20 move too, retaining their relative positions shown in full line in Fig. 3, the pushers 20 advancing a fresh blank towards the leading grippers (not shown in Fig. 3), on the bars 1, 1<SP>1</SP>. As the bars are moved apart to release a blank or blanks gripped between them, the blocks 6, 6<SP>1</SP> slide outwardly in the slots 5, 5<SP>1</SP> causing the links 8, 8<SP>1</SP>, member 9 &c. to move to the broken line position and the pushers 20 to combine feeding the blank until it is located between the leading grippers. The assembly 5-20 is returned to its starting position during the return and gripping strokes. If movement of the pushers is obstructed, spring loaded members 24 in housings 22 on the sleeve 12 are disengaged from a groove 25 in the rod 11 which is allowed to move with the bars 1, 1<SP>1</SP> to prevent damage to the feed device. As the lower member 24 is pushed back in its housing a microswitch 30 actuates an emergency device to stop the press.
