Title: Unloading station for conveyed pallets - has vertical lift frame across conveyor with horizontal clamp arms to lift layers on pallet
Inventor: HECKMANN WERNER
IPC: B65G59/02
Filed: 1976-04-30
Abstract: The unloading station for pallets has a floor level pallet conveyor (1, 2). A vertical lift frame (4) straddles the conveyor at the unloading position. Two horizontal clamp arms (5) are located by the lift frame so that they can be moved vertically. When the clamp arms (5) have lifted the top layer of the pallet load, two integral transport belts (7) transfer the load onto an exit conveyor (9). As the load height is reduced, the clamp arms (5) and the exit conveyor which is attached to them is lowered. Thus the load transfer from the pallet to the exit conveyor (9) is carried out in very short time.
Patent DE-2627017-A1 (DE)
Title: Warp beam transporter - using position switches to give automatic horizontal control while suspended from crane hooks
Inventor: MEYER KARL
IPC: D03J1/12
Filed: 1976-06-16
Abstract: While wound warp beams, together with their associated loom harnesses, are being transported from the warping station to the loom, there is an automatic horizontal control in one or two planes, laterally and longitudinally, while suspended from one to more crane hooks. This is effected by positional switches and transmission carriers to ensure that the crane's lifting point always remains over the centre of gravity of the total load, with its various attachments. The system ensures that the warp beam and loom harness are carried horizontally and accurately, without requiring large access areas for the transporter.
Patent DE-2638630-A1 (DE)
Title: Navigational instrument for sun sighting - has device automatically deriving light source elevation above artificial horizon
IPC: G01C21/02
Filed: 1976-08-27
Abstract: The instrument has a viewing device rotatable about a horizontal axis. Its light path running in radial direction to the axis, leads to a light detector which generates a signal when the light path points to the light source. The viewer (22) is rotated about the horizontal axis (30) at a speed specified by a motor. A reference device (50, 52, 54) delivers a reference signal when the viewer (22) is at a specified position w.r.t. an artificial horizon (20). An angle measuring unit automatically derives the elevation angle from the speed of rotation and time interval between the reference signal and detector signal. It gives the light source (56) elevation above the artificial horizon.

Patent DE-2654517-A1 (DE)
Inventor: SCHLEGEL HANS-DIETER ING GRAD
IPC: B25J9/04
Filed: 1976-12-01
Abstract: The arm of the gripper is carried by a lifting and swivelling unit driven by an electric motor. In addition, the lifting column of the lifting unit can be driven via a centrally arranged spindle drive. So that a simultaneous rotary and lifting movement can be achieved with simple means at as small a moment of inertia as possible, the spindle drive (13) is coupled to an electric drive (11) arranged outside the lifting column (14). In addition, the lifting column (14) can be swivelled via a gear rim (22) which is displaceable in the vertical direction relative to the lifting column (14) and to which the rotary movement of a further electric drive (21) can be transmitted via gearing (24). <IMAGE>

Title: Traffic rate measuring device in telephone exchanges - has first counter monitoring number of disconnections in series and second counter counts number of series
Inventor: SCHMITZ RICHARD
IPC: H04M3/36
Filed: 1977-04-05
Abstract: The telephone exchange has a central control which counts the number of the central control engagements. It counts the number of its disconnections after the connection time limiting becomes operative. The central control monitors all telephone calls. The number of connection time limiting operations occurring in series is measured separately, using two counters of which the first counts all time limiting operations carried out after the first, provided they occur after the preceding limitation not later than a specified period. The second counter counts the number of series.

Title: Tongued edged sheet metal cladding panel - has front embossed structured patterns and rear hollow foamed insulating plastics filling
Inventor: HEINEMANN HERBERT
IPC: B32B15/08
Filed: 1977-04-15
Abstract: The sheet metal panel, usually of aluminium, for interior and exterior cladding of buildings, has vertical longitudinal edges shaped as tongues and grooves. It is designed to provide a more appealing finish when applied as cladding over a large surface area. Plastically formed structured patterns (13) are impressed into the front side. The hollow space formed by the raised longitudinal edges on the rear side is filled with foamed heat-insulating plastics. In continuous production, a length of sheet metal runs in a single process through one or more pairs of rollers to impress the pattern, and through a coating position where the foamed plastic is applied.

Title: Connecting system fixing wires to substrate - applies second ultrasound dose to ensure wire passes through hollow electrode after bonding
IPC: H05K3/32
Filed: 1977-09-19
Abstract: The connecting system connects wires to a substrate using a hollow electrode through which the wire passes. The edge of the electrode presses the wire against the substrate where the wire is bonded to the substrate by ultrasound or similar. The electrode is then raised and the wire cut at the selected place. After bonding, the electrode is supplied with ultrasound at a lower level than that used for bonding to ensure that the wire passes through the electrode.

Title: Hydraulic tappet for IC engine valve gear - has adjustable piston with scroll port to vary valve timing while engine is running
Inventor: KEYLWERT JOHANN DIPL ING
IPC: F01L1/14
Filed: 1978-03-25
Abstract: The valves of the engine are opened against springs by rocker arms moved by push rods. Each push rod is raised by a piston (7) in an hydraulic cylinder(9). As it rises the piston uncovers the oil discharge port (12) in the cylinder. Oil is admitted into the cylinder through an inlet port (15) which is uncovered by a second piston (16). This piston is raised by the cam (18) through a follower (17). It compresses the oil to raise the first piston after it closes the inlet port. The timing is varied by rotation of the second piston (16) which has an inclined top face.

Title: Static pressure of gases measuring device - has oscillating element whose amplitude variations due to gas pressure changes are measured
Inventor: NICOLAI WALTER
IPC: G01L9/00
Filed: 1978-07-15
Abstract: An oscillating element (1) in contact with the gas is made to oscillate at a frequency equal or near to its natural frequency. The change of amplitude due to a change of gas pressure is measured either directly by measurement of a length, an angle or a piezopressure, or indirectly by measurement of the reaction of the oscillation amplitude on a variable electric parameter of the excitation system. The variable parameter used may be impedance, current voltage or a physical quantity effected through the gas by the oscillation amplitude, such as sound pressure or velocity. These variables are measured and used as an indirect measure for the static gas pressure.

Title: Two=part housing for telephone instrument - in which upper housing holds number selection panel and lower part circuitry components
Inventor: HANSBAUER HERMANN
IPC: H05K5/03
Filed: 1979-01-19
Abstract: The housing for a telephone instrument comprises an upper (17) and lower part which can be released from each other. The upper part (17) has a recessed area (18) in its outer face into which a number selection push-button panel and also indicating lamps (5, 6) can be fitted.
