Patent DE-2622989-A1 (DE)
Title: Bobbin change mechanism for a non-stop textile machine - can be loaded with enough bobbins to provide for several successive changes
Inventor: CARLSSON ERIC
IPC: D03J5/08
Filed: 1976-05-21
Abstract: Bobbin holders are mounted on a vertical loop of intermittently driven chain. The thread from each bobbin passes up through an open hook, then down to join the bobbin next ahead in the sequence: the thread from the first bobbin passes to the textile machine through a fixed eyelet. When the bobbin in the first position becomes empty, the machine is for a moment, fed from the second position: the consequent change in the run of the thread operates a microswitch to move the loop of chain round, and bring the second bobbin to the first position. The direct line between bobbins is shorter where the chain passes round the sprockets at the end of the loop, so a support is put between each pair of bobbins to take up this slack. The mechanism supplies of a single thread; it allows the operator to load, at a single occasion, enough bobbins to last for some time.

Title: Drink dispenser operated by drinking glass - has switching and relay system to swing tilting arm supporting glass
Inventor: HIRNSPERGER JOSEF
IPC: B67D3/00
Filed: 1976-06-14
Abstract: The drink dispenser is operated when a drinking glass is placed on a platform, so that a balance arm is tilted. A switch is operated by the arm and a timer relay actuated and a pump operated. At the same time a magnet attracts a weight and air is supplied to the arm to return it, and operate a piston. The switching system is operated by the piston so that the arm is tilted a second time and air is fed to the bottle to expel the contents into the glass. The weight falls back again and the arm is swung for a third time. The switching and relay arrangement operates again and the pump stopped and the arm is tilted for the fourth time to lower the glass.

Title: Land drainage clay pipe - has sloping end faces for internesting, may be oval to vary gap between pipes
Inventor: BRAUCHI PAUL DIPL ING
IPC: E02B11/00
Filed: 1976-07-07
Abstract: A clay pipe for draining land, has the face (22) at one end sloping inwards i.e. countersunk, and the face (24) at the other end sloping outwards and downwards so that the end of one pipe (21) can fit into the end of the next pipe (23). Side guides and supporting planks are thus not required when forming a continuous pipeline. In order to avoid damage to the ends, the sharp edges are omitted, both tube ends having a flat ring portion (24, 35). The sloping face can be made in the form of an oval, viewed on the end of the pipe, so that by rotating it through a small angle it does not seat completely against the next pipe, so that the gap between can be varied.

Title: Explosion-proof electric motor - has ignition-protection pressure-tight encapsulation and uses semiconductor temp. sensors
Inventor: KALLAS HANS DIPL ING
IPC: H02K11/25
Filed: 1976-08-06
Abstract: An explosion proof electric motor esp. a three-phase motor uses ignition-protection type 'd' pressure - tight encapsulation. It is suitable for coolant range from approx. -60 deg.C up to more than 40 deg.C. It uses semiconductor temperature sensors as a primary protection against dangerously high motor housing surface temperatures occurring, such that ignition of gas-air mixtures is prevented when the motor is operated in explosion-hazardous surroundings. The temperature sensors also guard against excessively high bearing(s) temperatures occurring, and are connected together to a sensing-current circuit. Two groups of semiconductor temperature sensors built into the windings of the motor and connected to the sensing-current circuit are specif. used as a secondary or back-up protection to sense the temperature of the windings of the motor operating in an explosion-hazardous ambient, and to allow for fluctuations of the coolant-medium temperature.

Title: Remote adjustment for external driving mirror - using endless loop belt about mirror pivot axis
Inventor: GUMMEL SIEGFRIED
IPC: B60R1/02
Filed: 1976-09-07
Abstract: The external driving mirror is adjustable about a vertical axis using a remote control in which an endless drive belt is threaded about the support and about a control knob (26) on the dashboard. The system can be used for mirrors on either side of the vehicle so that the driver can adjust the view without leaving the driving position. The mirrors are either adjustable permanently, or swing back to their original setting under spring pressure, whichever system is desirable. They can be adjusted when drivers are changed, or can be swung to cover blind angles in the rear view. An improved design has similar adjustments for the horizontal axes.

Title: Voltage divider with variable division ratio - has AC test voltage applied to divider to control variable resistance
Inventor: GIES JOHANNES DIPL ING
IPC: H03H11/24
Filed: 1976-09-15
Abstract: The division ratio is determined by a variable resistor used as a control element. DC (Ur) and AC (Ue) are applied to the input of voltage divider provided at its output with a filter (TP, C2) separating these two voltages (Ur, Ue). One of these voltages (Ue) is the voltage to be divided, and the voltage (Ur) is a constant amplitude test voltage. Output from the latter (TP) is applied, possibly through a rectifier to the first input of a differential amplifier (3). A variable control voltage (UF) whose amplitude is smaller than that of voltage (Ur), is applied to the amplifier second input. The variable resistor is set to such a resistance by the amplifier (3) output, that differential amplifier input voltages are as equal as possible. The variable resistor has about the same resistance for DC and AC.
