Safety devices in an offset printing machine prevent operation of the run button unless nip guards are in position and prevent the use of controls at different positions when a safety plate is moved to allow operation from one such position. The run switch has in series with it switches at each deck of the machine which are only closed, thus allowing it to operate the machine, when nip guards are in position at each deck to close the switch there. The control buttons may be provided at several positions and may be covered by a plate which must be moved to allow operation of the buttons and the movement of which breaks the circuits to the controls at the other positions thus rendering them inoperative while making the circuit to the control buttons thus exposed.

The body 152 is divided into at least two parts along at least one dividing surface lying between the objects 150 when juxtaposed. The body 152 is rotatable about its axis of rotation such that in one position the ends of the divided parts align substantially with the dividing surface and when the body 152 is rotated from the one position each part links at least two adjacent juxtaposed objects to fasten the objects against relative movement in at least one direction. One of the objects has at least one fluid passage 151 therein and at least one of the parts has a like fluid passage 156, the fluid passages 151,156 are being so disposed that when the objects are fastened together by rotation of the one part, the fluid passage in that part is aligned with the fluid passage in the object. As shown the two objects 150 form a housing each part 150 thereof having two passages and the body has two passages corresponding passages being linked when the objects are connected. The passages are at different levels. However, with passages at the same level (Fig 16, not shown) with the objects uncoupled one of the passages in each part connects both passages in the corresponding object.

Filed: 1972-12-05
Abstract: 1350738 Pressure regulators for anti-skid systems FIAT SpA 5 Dec 1972 [11 Dec 1971] 56126/72 Heading F2F A pressure regulator for an hydraulic antiskid braking system comprises a chamber connectible to an anti-skid control valve, an output port connectible to a brake actuator, a passageway between the chamber and the port controlled by means sensitive to pressure upstream of the chamber which closes the passageway if the pressure in the chamber decreases at a rate greater than a predetermined rate, and a restrictor throttle passage between the chamber and the port for fluid flow when the passageway is closed. A pump 10 supplies fluid to the brake actuators 76 via an electrically controlled valve 28 actuated by a known anti-skid circuit 31. A brake pedal 20 controls a valve 18 to allow fluid flow to a reservoir 12 when the pedal is not actuated. Fluid also returns to the reservoir 12 when the valve 28 is actuated by the circuit 31. Flow enters the regulator chamber 42 via a Venturi-tube 40, the reduced pressure in which acts on a piston 70 actuating a ball 68 controlling the passageway 52, 56. When the brake has been applied, and the valve 28 is subsequently actuated, the pressure in the chamber 42 drops, but that on piston 70 drops at a slower rate causing the ball 68 to close the passageway 52, 56. For the pressure decrease, fluid flows back to the reservoir 12 via a one-way valve 64. Upon subsequent increase of pressure (second cycle) due to action of the valve 28, the fluid passes through the throttle 60 to the actuators 76 producing a slower pressure increase at the actuators, the ball 68 still blocking the passageway 52, 56. A valve other than the electrically controlled valve can be used. Furthermore, the piston 70 may be subject to fluid pressure upstream of the valve 28.
