The table 7 is pivoted at 6 to a unit 5 slidable into and out of the housing 1 of the apparatus. Spring-urged pawls 13 pivotally mounted on the unit 5 have shouldered parts 13a which can be engaged with lugs 11 on the table 7 to hold the table in a lowered position so that when a stack of sheets is placed on the table 7 in the withdrawn position and the unit 5 is pushed into the casing 1 the pile 8 first passes beneath the roller 10. A stop 15 then engages the pawls 13 to release them, thus allowing the stack 8 to be pressed against the roller 10. Flanges 5a extend over the margins of the stack and ensure that the roller 10 removes only the uppermost sheet, the flanges being separated from the top of the stack by 0À1-0À5 mm. when the roller 10 is stationary.

Title: Level control for hydraulic press brakes and the like
IPC: F15B11/22
Filed: 1969-11-07
Abstract: 1,274,082. Hydraulic presses. NIAGARA MACHINE & TOOL WORKS. 7 Nov., 1969, No. 54684/69. Heading B5F. [Also in Division B3] A press brake or shearing machine comprises a pair of hydraulic piston and cylinder assemblies 11 and 12 for reciprocating a ram 10, pumps 20, 21 for supplying pressure fluid to the assemblies 11 and 12 via conduits 30, 31, means 46 for detecting advancement of one of the assemblies 11 or 12 beyond the other, a valve 52 which is normally shut but is shiftable to supply pressure fluid from a conduit 54 to either a conduit 60 or 61 in response to operation of the detecting means 46 so as to add pressure fluid to the assembly which is lagging behind the other. In operation a solenoid 83 is operated to move the ram 10 and valve 82 shifts to block drain passage 85 so that the full output pressure from pumps 20, 21 is applied to pressure reducing valves 67, 68. In the figure, directional valves 37, 38 are positioned to effect downward movement of the ram and are controllable as to direction by a solenoid 88 of a pilot valve 39. Due to a greater pressure in the conduit 54, any shifting of the valve 52 in response to movement of the detecting means 46 due to an out of level condition, establishes proportional pressure flow from conduit 54 past one or other of check valves 93 and 94 to the corresponding conduit 60 or 61 and thence through the corresponding conduit 63 or 64 to the main pressure conduit 30 or 31. Since conduits 30 and 31 are between the pressure reducing valves 67 and 68 respectively, and the associated directional valves 37 and 38, the higher fluid pressure from the conduit 54 causes fluid flow into the conduit 30 or 31, thus correcting the out-of-level condition by producing a relative advancement of the position of the lagging piston.

Abstract: 1,159,172. Automatic train control. GENERAL ELECTRIC CO. 9 Dec., 1966 [3 Jan., 1966], No. 55164/66. Heading B7N. [Also in Division G3] In an automatic train control system, the train is supplied from trackside apparatus with speed signals indicative of the speed limit of the track section being traversed and carries a radar ranging system providing signals indicative of the distance of a vehicle in advance and its speed is automatically controlled to the more restrictive of these signals. Signals modulated in accordance with the track speed limit are picked up from the rails by coils 37 and applied via receiver 39 to the selector circuits 41-45. In dependence on the modulation one or other of these circuits is energized and an associated relay HSR (high speed), MSR (medium speed), LSR (low speed) &c., picks up. Ranging signals from radar unit 22 are applied to threshold devices 30-32 with associated relays HVSR (high separation), MVSR (medium separation) and LVSR (low separation) and in dependence on the separation energize all, some or none of these relays. Contacts of these speed and separation relays in the speed and range aspect priority selector means select which of the speed signals, i.e. stop, low, medium and fast supplied from potentiometers 54-57, respectively, is applied to comparison means 62, the selection being determined by the most restrictive speed or range aspect. In the comparison circuit the tone is compared with an actual speed tone supplied from the tachogenerator 64 and the vehicle traction control 70 is controlled in accordance with the error.

Title: Ramp voltage generators

Filed: 1971-12-03
Abstract: 1399819 Ramp generators MARCONI INSTRUMENTS Ltd 6 Nov 1972 [3 Dec 1971] 56126/71 Headings H3T and H3P A ramp is produced by integrating a staircase voltage produced by a binary counter 1. The outputs of the binary counter are fed through weighting resistors 2-10 to the input of a summing amplifier 11 at whose output 13 the staircase appears. An integrating capacitor receives the staircase through a selected one of resistors 14, 16, 17 according to the range of the ramp voltage to be generated. Because the initial steps of the staircase provide a relatively low voltage for the capacitor voltage to charge towards, the initial part of the ramp has a slope different from the later part (Fig. 3(b), not shown); and to avoid this, a monostable 22 is triggered by the first pulse fed to the counter from 21 and provides in response a negative pulse (V s , Fig. 5a, not shown) which is added through R23 to the input of the amplifier. This gives the capacitor a negative level from which to charge towards the following first staircase step. By varying R23, the initial slope of the output ramp may be made concave or convex.
