Abstract: An apparatus for evening a printed stream of printed products comprising a number of revolving entrainment members which are in a drag connection with one another. At the region of their conveying-active path the entrainment members are guided and at the start of this path driven by a thrust drive and at the end thereof driven by a traction drive. The entrainment members engage the printed products and the thrust and traction drives cause a change in the spacing of the entrainment members and, consequently, in the spacing of the products.

Abstract: An expansion device for use in a reversible vapor compression refrigeration cycle for producing, upon demand, either heating or cooling. Two devices are mounted in opposed relationship in a supply line carrying refrigerant between a first heat exchanger and a second heat exchanger. Each expansion device includes a body having a flow passage therein opening into an expanded chamber. A free-floating piston is slidably mounted in the chamber and is moved to a first position when refrigerant is passed through the line in a first direction and to a second position when the direction of flow is reversed. A centrally located metering port passes through the piston while fluted channels are formed in its outer periphery. When in the first position, the fluted channels are closed against one side wall of the chamber and refrigerant is throttled through the metering port from the high pressure exchanger (condenser) into the low pressure exchanger (evaporator). Reversing the direction of refrigerant flow causes the piston to be moved into the second position wherein the fluted channels are opened to the supply line to allow an unrestricted flow of refrigerant about the piston.

Abstract: A method and apparatus for molding food patties, utilizing a pump with a tall, narrow, elongated pump chamber, an outlet port extending along one edge of the chamber, and a wide access port at one side of the chamber. A supply of hamburger or other poor-flowing food product is maintained in a position completely blocking the pump access chamber and can be drawn into the chamber by rapidly withdrawing a plunger from the chamber past the access port. A hydraulic drive powers the plunger, in synchronism with a mold plate cyclically moving into and out of a fill position beneath the outlet port; the hydraulic drive causes the plunger to pump food out of the pump chamber and into mold cavities in the mold plate under a constant pressure, with the hydraulic pumps of the drive cut off immediately following filling of the molds.

Abstract: An error correcting typewriter having separate elevating and feed mechanism for carbon and error correction ribbons includes a common cyclic motive source operable in response to type commands to drive a cam shaft which is axially shiftable by means of an electromagnet energized by a correction signal. Normally, the cam shaft is positioned in engagement with a carbon ribbon drive lever and out of engagement with an error correction ribbon drive lever. A shift of the cam shaft disengages it from the carbon ribbon drive lever and engages it with the error correction ribbon drive lever. The carbon ribbon drive lever simultaneously operates a carbon ribbon elevating mechanism and a feed mechanism. Energization of the electromagnet operates a lever which directly operates the correction ribbon feed mechanism and simultaneously shifts the cam shaft to engage it with the error correction ribbon drive lever which when driven is operative on the correction ribbon elevating mechanism.

Abstract: Reversing mechanism, particularly for semi-reversible ploughs, where the reversing mechanism includes hydraulic reversing cylinders (10, 11). The reversing mechanism, or device (5) to be reversed, includes a lifting arm (8) which at its one end is rotatably supported at a point (9) which the reversing mechanism turns about, and which at its other end is fastened to the device (5) to be reversed. The reversing cylinders (10, 11) have approximately the same volume and approximately the same length of stroke and are affixed symmetrically to the lifting arm (8). The piston rods of the reversing cylinders (10, 11) are rotatably attached (15, 19) with one end of a pressure arm (17, 18) whose other end is rotatably fixed to the point (9) about which the reversing mechanism rotates. Each reversing cylinder (10, 11) is single-acting and arranged to turn the lifting arm (8) approximately 110 degrees from horizontal position before the reversing cylinder (10, 11) has attained full length of stroke and the piston rod of the non-activated reversing cylinder ( 11, 10) is brought to abut against the abutment screw (21, 16) and brake the remainder of the reversing operation, which takes place with the aid of gravity. Two identical double-acting hydraulic steering cylinders (24, 25) are connected in parallel with the reversing cylinders (10, 11) and are thus arranged automatically to adjust, for example, the back wheel (4) of a semi-reversible plough when the reversing mechanism is activated.

Abstract: Impulses from the rotor blades (2) give rise to signals when the blades pass indicators (4, 5). The signals are detected and are used to calculate the blade angles. The rotor (1) is formed as a running wheel for a hydraulic machine, and the signals are received by at least two indicators located in the running wheel chamber wall (3) in a plane parallel to the wheel axis or in a plane parallel to the rotation centre of the blades when the running wheel is stationary. The impulse to the indicators received from each blade are detected as a signal group comprising at least two signals. Synchronisation of the running wheel axis w.r.t. the indicator position is achieved so that a specific signal group may be related to a specific blade. The received signals time difference in each group is measured so that the angle for the blade corresp. to the signal group can be calculated.
