Patent DE-2604322-A1 (DE)
Title: Fabric sack offtaker and setdown device - has two position swivel frame with lever and spring operated grip and release hooks over stacking table
Inventor: ESSER HANS-WILLI
IPC: B31B70/00
Filed: 1976-02-05
Abstract: A fabric sack offtaker and setdown device works downstream of the producer machine and places parted sacks direct on the stacking table. The frame (31) alternates between a first position parallel to the web of fabric sacks (69) and a second position parallel to the stacking table (20). Clamping hooks (47, 48, 49, 50) at the corners of the frame extend automatically to grip and retract automatically to set down the sack on the table stack. Two hooks (47, 48, 49, 50) should be mounted in pairs on shafts (44 and 41) and thus be extended and retracted for sack handling. Each shaft or each pair of hooks should have its actuator lever (60, 61, 62, 63) and a re-set spring (51, 54). Preferably the springs should extend the hooks, and the levers be actuated to retract the hooks to free the sack to drop on the stack.
Patent DE-2605759-A1 (DE)
Title: Commutatorless DC motor with rotor position detectors - detectors are around rotor circumference and respond to flux from poles (NL061076)
Inventor: MIYAZAKI KATSUAKI
IPC: H02K29/12
Filed: 1976-02-13
Abstract: The commutatorless dc motor requires no extra rotor for precise position indication. This is achieved by locating a number of position detectors around the circumference of the rotor that only respond to flux generated by the motor in a given direction, and by locating positioning magnetic poles opposite the detectors and poles to give this unidirectional flux response in the detectors. Each position detector consists of a magnetic amplifier and a permanent magnet. The arrangement prevents two or more excitation windings being excited simultaneously, and also prevents none of the windings carrying current when the motor is switched on.

Title: Monitor for strip film and print cutting machine - compares numerical codes on one strip with count of other and converts optical into electrical signals
Inventor: SCHNEIDER HORST
IPC: G03D15/00
Filed: 1976-02-20
Abstract: A long band of connected-up strips of negative (13) and another of the corresponding prints (3) are both cut into units by the machines. Sequential number codes read from the prints (10) are compared with a count of the films (20) and the two results displayed (23-24). Alternatively, or in addition, the values may be compared automatically and a switch thrown, or a warning given, when they do not agree. The optical signals are converted into electrical signals in a decoder (25) and a counter (26) and applied to the comparator (27). The machine relieves the operator of the tasks of checking by direct visual comparison of prints and negatives.

Title: Longitudinally welded pipe made from copper strip - using helium round welding zone to exclude air, thus raising weld strength
Inventor: ZIEMEK GERHARD DR ING
IPC: B23K9/23
Filed: 1976-06-23
Abstract: Longitudinally welded copper pipe is made from Cu strip contg. 0.002% O2, 0.001% S, 0.02-0.3%, pref. 0.025% P, balance Cu. The strip is formed into slit tube, and the slit is welded by one or more electric arcs in an inert gas atmos.; the welded pipe may then be corrugated if required. During welding, but while the longitudinal slit is still open, an inert gas (1) is fed into the pipe; gas (1) has a density lower than the density of air and forms a protective curtain round the welding zone. Gas (1) is pref. helium which flows beyond the welding zone to a point where the weld is still at 200 degrees C. The pref. pipe forming and welding plant includes a He tank and a pipe feeding the He to a trough located in the Cu pipe in the welded zone, the top edges of the trough being provided with a flexible asbestos seal. The weld in Cu pipe can possess grain boundary weakness due to the presence of oxides; this weakness is unsatisfactory for pipes subjected to press. and/or stress. By using Cu strip with the low O2 content given above, a weld with 90% of the strength of the strip can be obtd.

Title: Steam hair curling tongs - produces steam by wick from water holder held against an evaporator
Inventor: AMBUEHL HANS
IPC: A45D1/04
Filed: 1976-09-09
Abstract: These steam curling tongs consist of a plastic handle (1) from which project an aluminium cover tube (2) and a pivoted clamp tongue (3). A plastic cartridge (3) containing water is fitted in the end of the cover tube (2). This cartridge (7) is filled by means of a filler cap screwed into its outer end which also acts as a piston forcing water into a wick in the inner end. To produce steam, the cartridge (7) is pushed into the cover tube (2) until the wick rests against an electrically heated evaporator shell (5). The resulting steam passes along grooves in the evaporater shell and out into the hair through rows of outlet holes (21) in the cover tube (2). A gasket (55) prevents steam from continuing down the tube to the handle. This method provides a simple steam tong which only produces steam when required and does not heat or over cool.
