Abstract: 1518749 Rotary positive-displacement fluidmachines ARTHUR D LITTLE Inc 23 Aug 1976 [3 Nov 1975] 35079/76 Heading F1F [Also in Division F2] In a scroll-type machine, which may be a compressor, an "expansion engine", or a pump, the spiral elements, or "wraps", 13, 15 of fixed and orbiting "scroll members" 10, 11 have channels 70, 71 and 105, 106 therein for a coolant, such as oil or water, for which there may be also spiral channels 50, 102 in end-plate assemblies 12, 14 of the scroll members. The coolant in the channels 102, 105, 106 may be oil taken through passages 145, 146 from a ring of pockets 136, which facilitate lubrication of the assembly 14 and also pressure loading of the orbiting scroll member 11  towards the fixed one. Spring-loaded sealing elements 63, 107 may be lodged in the free edges of the wraps. To reduce leakage tangentially of the wraps and reduce friction layers 12a .. 15a of a self-lubricating material e.g. P.T.F.E., may be applied to the end-plate assemblies and wraps. Oil in a sump 152 is cooled by a coolant, such as water, in finned tubing 170 and is fed to the pockets 136 by a pump 173. A power-input, or output, shaft 175 carries a balancing weight 205 and is connected to a shaft 182 secured to the scroll member 11 by a "swing link" 180 comprising a counterweight 183 housing a bearing 181, a further counterweight 184, a pivot pin (190), Figs. 9, 10 and 11 (not shown), and a disc 193 of self-lubricating material held in place by a screw 194, the disc being said to prevent vibration. To compensate for wear at the lateral surfaces of the wraps the counterweights are also inter-connected by an adjustable spring device (198), Fig. 9, which keeps the wraps in contact with each other, movement of the wraps towards each other being limited by a stop (196), comprised in said device, so as to prevent excessive wear.

Abstract: A manipulator apparatus having a manipulator arm movable in a plurality of axes is programmed to perform a desired sequence of operations over a desired path. The programming is accomplished by an operator manually moving the end of the manipulator arm over the desired path while encoders associated with each axis of the manipulator apparatus produce signals representing movement of the arm in each of the axes. The encoder signals are automatically recorded at predetermined increments of movement of the arm as command signals for controlling movement of the arm during a playback cycle. Recording of these command signals is controlled by a guide wheel which is positioned on the end of the arm during programming and is rotated by maintaining the wheel in contact with the work as the operator moves the manipulator arm over the desired path. Control pulses are generated for each predetermined increment of rotation of the guide wheel and these control pulses are employed to control recording of the encoder output signals. Weld cycle controls, weld speed controls and a manual record control are provided. The manual record control is actuated to record positions between welds wherein the end effector is moved between weld paths without the guide apparatus being in contact with the welding work surfaces. During programming, guide strips having tracks into which the guide apparatus is placed, may be positioned along the desired weld path by the operator. The recorded signals corresponding to the distances the arm is to be moved in each of said axes are utilized during a playback cycle to control drive apparatus for each axis, such as stepping motors, which are de-energized during the programming phase. During playback a welding tip or other implement is positioned in place of the guide wheel apparatus whereby the manipulator performs the desired operation over the programmed path at a predetermined, selectable speed independent of the programming speed. The recorded command signals are effective to drive pulse generation circuitry during playback to produce pulse trains that are supplied to the stepping motors so that they are moved at the required velocities to perform a weld over the programmed path.

Abstract: This device for the separation of a mixture of at least two small components in which one is of a smaller density than the other is designed as a cleaning device for berries. The apparatus comprises a first chamber (1) for receiving uncleaned berries and a second chamber (2) that is connected to the first through an inlet orifice (8) with a limited area. The first chamber has a concave or in principle flat bottom (3). The second chamber (2) has a first bottom section (7) that continues the bottom (3) of the first chamber (1) and limits the inlet orifice (8) downward and a second bottom section (12) that is at a higher level than the first bottom section (7) from which it is separated by an inlet orifice (13) for cleaned berries. Above the second bottom section (12) at an even higher level, the second chamber (2) has an outlet (14) for the lighter mixture component. The outlet (14) is designed to be connected to a vacuum or other suction source. The path from chamber one's bottom to the air outlet (14) is thus curved. Because of this shape and the high speed the berries obtain when passing through the orifice (8), they continue straight along the bottom section (7), while lighter leaves and the like follow the airflow out through the air outlet (14).<IMAGE>

Abstract: An identification card, in particular an all-plastic indentification card, written on by means of a laser, having user-related and user-neutral data such as a name, account number, etc. present on the surface of the indentification card in the form of local discolorations of the identification card material without any transition. Due to a local increase in tensile strength, these decolorized areas have greater resistance to mechanical changes and/or chemical solvents than the surrounding areas of the identification card made of the same identification card material. Thus attempted falsification by means of mechanical and chemical means is prevented in an especially effective way, since such attempts lead to destruction of the identification card in each case. The personalization of the identification card with the freely selectable user-related data can take place by preference decentrally by means of a laser beam, the energy of which is controlled in such a way that the identification card material is decolorized but not destroyed.

Abstract: The raw material is reduced to the required cross sectional area. It is then shaped to the required profile in a mill. At this stage its linear movement speed is sensed before and after the mill. By comparison with a reference value, the position and/or pressure applied is controlled to achieve the desired profile. The linear e.g. thread-like item passes through the tension discs which reduce its diameter and correct its round shape. The devices provide the necessary force to pull the thread. It then passes measuring wheels which register its linear speed. Between there there is a grooved mill to profile the product.
