Abstract: 1,020,456. Springs. E.T.A. A.G. EBAUCHES-FABRIK. Oct. 30, 1962 [Nov. 1, 1961], No. 41082/62. Heading F2S. [Also in Division G3] The rundown time of a clockwork spring barrel is increased, albeit with some slight loss of power and timekeeping ability in a later stage of the rundown, by a particular mainspring. This spring, Figs. 1-10 (not shown), comprises a spirally coiled blade, characterized in that an outer length 6 thereof adapted for connection to the barrel, is of the same thickness throughout, so as to deliver the correct driving force, whilst a second length 7 extending inwardly from the outer length and adapted for connection to the arbor, is of lesser thickness than the outer length 6. This enables the diameter of the arbor to be reduced and the space available for the spring to be increased. The thickness of the outer length may be <SP>1</SP>/ 25 th of the diameter formed by the inner length when fully wound. The inner length 7 may also be of uniform thickness, but in one form it is made of uniformly increasing thickness from its inner end outwardly to its junction with the length 6. The rate of increase of thickness, from known rules concerning the smallest diameter to which the turns can safely be wound, is made as great as possible, to keep the inner length relatively short and improve the power/time characteristic. The spring may be in one piece or the lengths welded or riveted.

Abstract: 1,040,077. Driving record tapes. MAGNAVOX ELECTRONICS CO. Ltd. Oct. 9, 1964 [Oct. 18, 1963], No. 41275/63. Heading G5R. The take-up spool holder 14 is directly coupled to a wheel 24, Fig. 3, which is coupled by a felt washer 26 to a further wheel 25; the supply spool holder 13 is directly coupled to a wheel 21 engaging an idler roller 23; and an idler roller 27 is movable axially and transversely to engage 25, 24 or 23 to provide drive for normal operation, fast wind or fast re-wind respectively. The drives are selected by one of three piano keys 60-62, Fig. 1, depression of which moves a corresponding operating bar 69, 67 or 70 the end of which is provided with a pin 71 which enters a groove 72 in a locking plate 73 to prevent actuation of either of the other two keys while the third key is depressed. When the normal play key 61 is depressed, a lug 85 on bar 67 engages an arm 86 of a bellcrank 56 and rotates it, thereby moving a lever 70 which rotates the arm 37 supporting roller 27 to move the latter so that it transmits drive from driving pulley 8 to the wheel 25. At the same time a pivotal link 79 attached to bar 67 causes rotation of a mounting plate 77 thereby causing pressure pads 84 to press against the heads 2 and causing a pinch roller 76 to engage the capstan 5. For fast wind key 60 is depressed, and a lug 89 on bar 69 causes rotation of arm 37 as before; in addition, the end of the bar engages and rotates a lever 42 provided with an inclined cam head 45 which raises the arm 37 on its spindle 40 against the action of a spring 41 (shown in Fig. 3). Thus the roller 27 transmits drive to wheel 24 instead of to wheel 25. For fast re-wind key 62 is depressed and a lug (not shown) on its operating lever 70 engages one arm of a bell-crank 52 thereby rotating arm 37 in the opposite direction so that idler 27 transmits drive to the wheel 23. A pulley 20 may be provided on the supply spool holder for driving a spool capacity indicator.

Title: Motor vehicles having independent suspension for the steered wheels
IPC: B60G3/20
Filed: 1969-08-20
Abstract: 1285047 Vehicle independent suspensions BAYERISCHE MOTOREN WERKE AG 20 Aug 1969 [20 Aug 1968] 41551/69 Headings B7D and B7H  The steered wheel of a motor vehicle is suspended from the vehicle frame by upper and lower suspension linkages of which at least one is formed by a pair of mutually independent arms connected at separate points, e.g. by ball joints, to a stub-axle carrier and the vehicle frame. As shown in Fig. 6 an upper suspension member comprises a wishbone 11 having a ball-joint connection 12 to the stub-axle carrier 31, while the two lower suspension members form a pair of independent arms 50 connected at points 6<SP>1</SP> to the stub-axle carrier. The swivel axis of the wheel is thus the line 10<SP>1</SP>, connecting the ball-joint 12 to the point of intersection 9<SP>1</SP> of the axes 50<SP>1</SP> of arms 50. In another embodiment (Fig. 7, not shown) the two arms are connected to the upper part of the carrier, and the wishbone to the lower. As shown in Fig. 2, four arms are provided and arranged in pairs 4, 4 and 5, 5, the arms of each pair being coplanar and all the arms having a symmetrical disposition. In another embodiment (Figs. 8 and 9, not shown) four arms have an asymmetrical disposition, a spring and damping element (17) also being provided and pivotally connected to the carrier and frame, preferably the point of attachment (18) of this element to the frame lies on the effective swivel axis of the wheel. The asymmetrical disposition of the arms is said to counteract forward pitch of the vehicle during braking. As shown in Fig. 10, a spring strut 21 provides a linear guide arm for the wheel while two suspension members forming a pair of independent co-planar arms 22 have ball-joint connections 24 to the stub-axle carrier. In another embodiment (Fig. 13, not shown) similar to the embodiment just described, the two arms are non-co-planar. The swivel axes of two wheels on transversely opposite sides of the vehicle may be so inclined as to normally intersect either above or below the surface on which the vehicle stands. Specification 1,285,048 is referred to.

Abstract: 1437757 Valve TOMCO Inc 27 Sept 1974 [4 Oct 1973] 42094/74 Heading F2V [Also in Division G3] A spool valve has a body 12, a bore 14 with a pair of recesses 16, 17; a fluid inlet 24 to which recess 16 is connected; a discharge 26 to which recess 17 is connected; a pair of passages 30, 30<SP>1</SP> for fluid flow between the valve bore at the recesses 20, 21 and a work cylinder (not shown); a pair of passages 35, 35<SP>1</SP> linking the cylinder recesses 22, 23 with discharge ports to take exhaust fluid to a tank (not shown) and a pressure passage 28 to take fluid from the inlet 24 to the valve bore at recesses 18, 19 via a control orifice 104. The spool 46 is slidable in opposite directions from a neutral mid position to cause pressure fluid to flow from the pressure passage to one of the cylinder passages and exhaust fluid to flow from the opposite end cylinder passage to an exhaust passage. Spool movement is controlled at its ends by fluid at inlet pressure via passages 72, 44 and restrictors 45, 45<SP>1</SP>. The spool is moved by venting one end control pressure through the solenoid valve 88 or (88<SP>1</SP>) (not shown) so that a ball 76, 761 is moved away from the spool relieving it of load from the spring 78 or 78<SP>1</SP>. When the spool is in an operative position the space between its end and the ball towards which it is displaced is vented to the pressure of the pressure passage via the check valve 27, 27<SP>1</SP> and passages 52, 52<SP>1</SP> 54, 54<SP>1</SP>. The restriction 104 may be formed by a valve member 102 lifted against a spring as determined by the current to a solenoid pilot valve 116. The differential pressure across the restriction 104 determines the position of the spool and hence the flow rate is maintained substantially constant by spool movement to compensate for pressure changes across the orifice. In a modification the solenoid valves 80, 80<SP>1</SP> and 100 are replaced by a rod operated valve assembly (210), Fig. 8 (not shown). In a further modification a manually set restriction, Fig. 6 (not shown), replaces the solenoid assembly. Pressure on the spool at the neutral position is maintained by a spring loaded valve (154), Fig. 9 (not shown). Valve assemblies (130), 130<SP>1</SP> at each end of the spool valve provide for an increased flow rate and reduce the time for spool return to neutral.
