The device of the parent Specification is modified to enable it to be used for stopping the motion of a member other than a suspended element and accordingly the winding drum is omitted and the lever 10, 11, which is rotatable about fixed spindle 7, is engaged directly by a rod 1 coupled to the member to be retarded, such engagement causing the lever to apply torsion to one end of a spring 13 arranged in a bore 16 of inertia flywheel 17, whereby the spring expands and frictionally engages the flywheel to cause it to rotate and thus absorb the energy of the member prior to end 11 of the lever engaging an adjustable stop 4. The latter is adjusted to bring the member to rest without rebound or undue shock the continued rotation of the flywheel releasing the spring torsion whereby the spring contracts and friction between it and the flywheel reduces to allow slippage until the flywheel comes to rest. A spring 20 returns the lever to its initial position when the rod 1 is withdrawn.

Abstract: 1,156,633. Automatic speed control. AMBAC INDUSTRIES Inc. Oct. 7, 1966 [Nov. 12, 1965], No.44873/66. Heading G3R. The speed of a diesel engine 10 is regulated by fuel controller 12 responsive to signals fed to winding 14 of actuator 16 which is spring-biased in a direction to decrease the fuel supply. A loadbearing gear 22 co-operates with speed-senser 30 producing an original signal having a frequency which varies with the speed of the engine and is variable in amplitude. A saturating amplifier 36 provides a train of pulses recurrent at the frequency of the original signal but of substantially constant amplitude, the widths of the pulses varying inversely with their frequency. The output of the amplifier 36 is applied to filter 80 whose output pulses have amplitudes dependent upon frequency, the response characteristic of the filter having a steep lowerfrequency skirt extending over a limited band wherein the amplitude of the output pulses increases substantially linearly with increase of frequency. A variable inductor 98 permits shifting of the frequency position of the lower-frequency skirt over a range which is large compared with the band occupied by the skirt at any given time. The pulses from the circuit 80 are supplied to a rectifier and D.C. filter 106 to produce a continuous direct voltage which varies in accordance with the amplitude of the input pulses. Thus, the voltage across leads 108, 110, has a value proportional to the pulse frequency when the latter lies within the band occupied by the skirt. The D.C. signal is applied to three-stage transistor amplifier 130 whose output feeds the winding 14. Upon starting, the fuel control is opened by a large current from the D.C. amplifier until the frequency of the original signal reaches the band occupied by the skirt, after which the control signal decreases with increase of speed to stabilize the engine against load variations. The regulated speed is adjusted over a substantial range by adjusting the value of the inductor 98.

Abstract: 989,233. Semi-conductor devices. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORPORATION. Dec. 22, 1961 [Dec. 26, 1960], No. 46061/61. Heading H1K. A semi-conductor device having bilaterally bi-stable characteristics (see Fig. 2) comprises monocrystalline silicon having a resistivity of at least 300 ohm-cm., the silicon having alloyed to each of two opposite surfaces an electrode consisting of gold or gold alloy containing less than 5% of one or more elements selected from Group V or Group III of the Periodic Table. Where the silicon is N-type, Group V impurity such as antimony, phosphorus or arsenic may be used in the gold alloy. Where the silicon is P-type, Group III impurity such as gallium, boron or aluminium may be used in the gold alloy. If a current is passed through the device from one electrode to an opposite electrode at room temperature, irrespective of the direction of current flow, the voltage/current characteristics of the device include a negative resistance region 4 or 4<SP>1</SP> between two positive resistance regions, so that a load resistance may be connected to the device to provide two stable operating points 2, 5 or 2<SP>1</SP>, 5<SP>1</SP> in either direction of current flow. Monocrystalline N-type silicon 1 (Fig. 1), cut so that its two major faces are (111) crystollographic surfaces, is etched and water washed. The silicon is of high purity and is made by a zone refining process. Its specific resistance is 1000 ohm-cm. and the life-time of injected carriers is 1/1000 sec. Two gold strips 2, 3, preferably containing a Group V element, are pressed and fused to the crystal. The piece is heated for 10 to 30 minutes in a vacuum or inert gas to alloy the strips with the silicon. The heat-treated piece is etched, water-washed and sealed in a vacuum or inert gas. Alternatively, P-type silicon replaces the N-type silicon, the electrodes being gold strips preferably containing 1% gallium or other Group III element. A matrix of semi-conductor devices may be made by alloying two pairs of three strips of gold to monocrystalline silicon (Fig. 3). In another example (Fig. 5) monocrystalline silicon 1 is cut to provide two opposed (100) crystallographic faces. Gold wire held in a jig is lightly pressed on to both faces while the assembly is held at 400 C. for 10 to 30 minutes in a vacuum or inert gas. After the heat treatment the alloyed parts are tetragonal pyramids.

In operations that involve only customers' accounts, a control slip is printed at d instead of an account card. The carriage 104 for the account card is positioned in the machine by a handle 107, Figs. 12 and 13, that serves also as an index to show the line of the card that is in printing position. The carriage is resiliently held in adjusted position by a detent 136 urged by a spring into engagement with a line-spacing rack 109 on the carriage. Line-spacing is effected in itementering operations by a floating lever 110 mounted by rollers 111, 112 in guide-slots 113, 114 and urged by a spring 115 towards the rack 109. The floating lever is operatively connected through link 117, lever 118, and link 120, to a lever 121 pivoted centrally on a slide 125 that is shifted to the right by a cam 129 during each machine operation. In old and new balance operations the lever rocks idly about the pivot 121<1>, but in item-entering operations its upper end is restrained by a plate 130 controlled by the accumulator keys with the result that the lever 121 rocks counterclockwise and actuates the floating lever to effect line-spacing. When a control slip is to be printed the carriage is adjusted to the position shown in which the floating lever cannot engage the rack and no line-spacing occurs. After printing has taken place on the last line of an account card, a stop 138 on the carriage shifts a slide 139 inwardly, whereby a stop 144 is positioned in the path of a shoulder 153 of a plate 146 and depression of a key to initiate a new operation is prevented.

A fluid-operated brake adapted to stop the rotation of a declutched shaft and hold it at a definite angle of rotation comprises in combination an annular cylinder 10 fixed on the machine frame and having two annular walls 18, 19, an open end and a closed end, an annular piston 11 shiftable in the annular cylinder, an annular brake disc 12 rigidly connected with at least one of the annular walls of the annular cylinder and arranged in front of the open end of the annular cylinder, apertures 22 being distributed around the outer border zone of the annular brake disc, outward projections 33 extending from the periphery of the annular piston and through open-ended recesses in the outer annular wall, a pressure ring 13 on the outer side of the annular brake disc, axially shiftable pins 23 mounted at one end in the pressure ring and coupling the pressure ring with the outward projection, said pins extending through and being guided by the apertures distributed around the outer border zone of the annular brake disc, and a brake disc 14 rigidly secured to the shaft and engaging between the annular brake disc fixed on the annular cylinder and the pressure ring fixed on the annular piston. The annular cylinder 10 is bolted to the frame through a flange 15. The working fluid, e.g. compressed air or oil, is introduced into the interior 16 of the annular cylinder through a connection 17. A flange 20 on the inner annular wall 19 serves as an abutment for the annular brake disc 12, the apertures 22 of which guide the pins 23. The annular piston 11 is U-shaped in cross-section and shrouds a series of springs 27 which seat on rings 26, 30, the former seating in an annular recess 25 in the face of the annular brake disc 12. The brake disc 14, which is welded to a hub 34 keyed on the shaft, has apertures in which are brake blocks 38 which are axially movable. The annular brake disc 12 bears against a flange 40 on the annular wall 10 through a heat insulating member 42. A heat insulating member 21 is inserted between the annular brake disc 12 and the flange 20. The Figure shows the brake in the " on " position, with the springs 27 forcing the annular piston 11 to the right as shown in the Figure, and the force is transmitted through the pins 23 and pulls the pressure ring 13 against the brake blocks 38 which it forces against the face 24 of the annular brake disc 12, which is fixed, and the brake disc 14 is therefore held against rotation. The brake is released by the introduction of fluid under pressure into the space 16. Cooling ribs 35, 36, 37 are provided on the hub 34 and pressure ring 13. In a modification the number of brake discs could be multiplied.
