Patent DE-2414105-A1 (DE)
Title: Concealed actuating mechanism for piston jacks for infinite adjustment - has control lever inserted in opening of sealed cylinder extension
IPC: A47B9/00
Filed: 1974-03-23
Abstract: The lifting mechanism or jack comprises a cylinder housing which is extended beyond and actuating ram so that an actuating lever for the valve ram is guided through an opening in this cylinder extension and held by an actuating member which abuts the valve ram and is mounted in the extension to be axially displaceable but relatively free of play in the radial sense. The end of the actuating lever is mounted in the actuating member so as to swivel but not move longitudinally and is supported against the cylinder extension near the opening in the side of the latter. Since only one opening need be provided in the cylinder extension no undue weakening is likely to occur and with no parts protruding beyond the extension the overall appearance is neat. Used especially for height adjustable tables and chairs etc.

Title: Permanent magnet device for lifting upper eyelid - is mounted to spectacle-frame and interacting with magnet on eyelid
Inventor: LENNE HEINZ DR MED
IPC: A61F9/007
Filed: 1974-04-08
Abstract: The device for lifting or opening the human upper eyelid, in case of ptosis of the upper eyelid or myasthenia gravia, comprises a permanent magnet mounted to a spectacle-frame. The permanent magnet is brough sufficiently close to a magnet implanted in the inner eyelid or placed externally on it. The paralysed upper eyelid is thus opened by magnetic attraction and when the spectacle-frame is moved, wholly or partly closed again. Direct manual contact, which can be difficult and painful, is avoided. The magnet is attached to a lever linkage.

Title: Pressure arrangement on magnetic head in tape recorder - presses magnetic tape against head using elastic leaf spring
Inventor: SIEGEMUND RICHARD DIPL ING
IPC: G11B15/62
Filed: 1974-06-19
Abstract: The spring (6) is positioned opposite the magnetic head and the operating gap (5) of the magnetic head is arranged at the side of the pressure transmitting medicon (7) which consists of a bundle of fibres.

Title: Electromagnetic brake for curtain actuator motor - with the coil supplied via a rectifier in series with the motor achieves reduced voltage drop
Inventor: IVKOVIC ZORAN DIPL ING
IPC: H02K7/102
Filed: 1974-10-02
Abstract: In curtain actuators the brake is released electromagnetically when the motor is switched on, and the simplest control system employs brake and motor windings which are connected in series. In this connection the voltage available for the motor is only about 90% of the supply value. By placing a bridge rectifier (5) in series with the motor windings (1, 2) the voltage drop across the brake release circuit (6) is reduced to approx 2-3% of the supply value allowing a higher voltage to be developed across the motor (4). The dimensioning of the motor can be optimised and the space requirements may be reduced.

Title: Cables with extruded plastic coating pass to a vulcaniser - separated from extruder to allow inspection of coating for faults (SW280676)
Inventor: GRAEBER AUGUST
IPC: B29C48/06
Filed: 1975-07-30
Abstract: A cable is coated with a plastic coating in an extruder and advanced to a vulcanizing chamber which is separated from the extruder. Immediately adjacent the entry end to the vulcanizing chamber is a sealing tube through which the cable passes guided by internal guide plates with guide apertures for the cable. A sealing fluid is pumped into the sealing tube through an inlet to produce a pressure in the sealing tube slightly greater than the pressure in the vulcanizing chamber. The various compartments formed between the guide plates in the sealing tube are connected to exhaust ducts. The cable passes through a free space between the extruder and sealing tube so that the coating can be visually inspected for faults.
