Title: Improvements relating to vehicles with regulating means for maintaining the body at a constant height
IPC: B60G17/033
Filed: 1964-03-20
Abstract: 1,015,210. Vehicle suspensions. DAIMLERBENZ A.G. March 20, 1964 [March 23, 1963], No. 11952/64. Heading B7D. A motor vehicle self-levelling suspension comprises hydropneumatic suspension units interconnected in front and rear pairs, each pair being supplied with pressure fluid by a pump or exhausted to reservoir through a control unit. Each control unit comprises a shuttle valve 18, a non-return valve 19 and stop valves 20, 21 and 22. A lever 24 is pivoted at 25 to the unit and connected by a link 28 to the axle 29, there being tappet members 26 and 27 screwed to the lever and coacting with tappet rods 20<SP>1</SP> and 22<SP>1</SP>, the rod 20<SP>1</SP> coacting with valve 20 and the rod 22<SP>1</SP> being in two parts, 22<SP>1</SP> and 21<SP>1</SP> separated by the valve 22 and coacting with the valve 21. In the initial position the shuttle valve 18 is maintained in its right-hand position by the pressure of the fluid in the lines 12, but when load is placed on the vehicle causing the lever 24 to move in the direction of the arrow X, the valve 20 is opened and the pressure in the line 16 and duct 23 acting upon the face 18<SP>11</SP> of the shuttle 18 exceeds that acting upon the face 18<SP>111</SP> of the shuttle which moves to the left, causing a build-up of pressure on the face of the non- return valve 19 which opens to allow fluid to pass into the suspension units to restore the initial position. An operational check is obtained by a momentary opening of the valves 21 and 22 by the tappet 27 acting on the rod 22<SP>1</SP>, the action being similar to when load is taken off the vehicle, and liquid flows from the duets 23 and 16 to reservoir and the shuttle 18 returns to the right-hand position.

Abstract: 220,062. James, R. W., (Remington Typewriter Co.). May 8, 1923. Portable machines; carriage-releasing arrangements; paper-carriages; carriage-shift mechanism; locking-devices; key locks. - In machines that are adapted to be collapsed and enclosed in a carrying-case, a collapsable part of the machine automatically controls a carriage-releasing device, a carriage-centring lock, and means for holding the shift-carriage in the normal position and for releasing the shift-key lock. The Figure shows part of a portable machine comprising (1) typelevers adapted to be collapsed and expanded by means of a vertically-movable frame 99 connected by links 110 to arms 108 on a shaft 102 which can be rocked bv means of a hand-lever 104, (2) a paper-carriage 19 running on a support 4 secured to a shift frame, movable rearwards by means of a shift-key lever 35 which carries a locking-key lever 39 having a lug 42 for engaging a plate 45, (3) letter-spacing mechanism comprising a rack 49 on the paper-carriage, and cooperating fast and loose dogs 71, 53 mounted on a plate 56 which is pivoted at 57 to a rocker 60 operated by a universal bar pivoted on the shift frame, the plate 56 being provided to permit yielding of the loose dog when the carriage is returned, and (4) an enclosing-case which, after collapsing the type-levers, centring the papercarriage, and returning the shift frame to normal position, can be folded over the machine. The shaft 102 is now adapted to operate the means referred to above. For releasing the papercarriage, the shaft 102 is formed with a crank 103 connected by a link 129 to a lever having a pin 135 adapted to engage, the plate 56 carrying the dogs 53, 71. The centre-lock consists of a blade 143, pivoted to a bracket 145 on the carriage support 4, and having a stop 146 co-operating with a stop 140 on the carriage. The stop 146 is formed with a notch 149 and inclines 148, and the stop 140 is pivoted on the carriage, and engaged by a spring 142. A lug 150 on the blade 143 engages a slide 151 which is connected by a link 152 to an arm 159 on the shaft 102. When the shaft is rocked, an incline 155 on the slide raises the blade, and the stop 146 is brought into the path of the stop 140, whereupon the carriage runs or is moved by hand until the stops engage and lock the carriage against movement in either direction. The locking-key lever 39 is released by means of a finger 125 formed on a slide 122 which is connected by a link 118 to an arm 121 on the shaft 102. If the key-lever 39 is locked when the shaft rocks, the finger engages the lug 42, the key-lever being thereby released, and the shift-frame permitted to return to the normal position. The finger also prevents effective operation of the key-lever until the shaft 102 is returned to normal position. To prevent rearward movement of the shift frame when the machine has been collapsed, the shaft 102 is formed with fingers 126 adapted to engage a member of the universal bar, which, as pointed out above, is mounted on the shift frame. Specification 220,061 is referred to.

Abstract: 747,928. Electric correspondence control systems. SMIDTH & CO., AKTIESELSKAB, F. L. April 28, 1954, No. 12363/54. Class 40(1) The weight of material delivered in unit time by a conveyer is maintained constant by detecting the weight on a supporting roller and varying the speed of the conveyer in inverse proportion. The material is fed in a substantially uniform layer from a hopper 1 to a conveyer 2 driven by a motor 6 via a manually adjustable infinitely-variable speed gear 8 and an automatically adjustable infinitely-variable speed gear 10. The roller 12 responsive to the weight on the conveyer is carried on a frame 13 pivoted at 14 and linked to a counterbalancing frame 27 pivoted at 17 and carrying an adjustable counterweight 18. The servomotor 23, controlled by contacts 25, 26 adjusts the weight 18 via a flexible shaft 19 and screw 16 so that the frame 27 is self-balancing. The motor 23 simultaneously corrects the speed of the conveyer by adjustment of gear 10 via shaft 20. The rate of delivery is manually adjustable by gear 8. The total weight delivered is indicated by a counter driven at.a speed proportional to that of the conveyer. In a modification Fig. 3, (not shown) the same infinitely-variable gear is used both for the automatic and the manual control of conveyer speed, and limit switches on either side of the counterweight actuate an alarm should the deviation in weight be excessive.
