Title: Pneumatic post receiving station - uses magnetic valve operated by transport cylinder to interrupt drive air flow from blower
Inventor: TONNE FRIEDRICH DIPL ING
IPC: B65G51/30
Filed: 1975-05-09
Abstract: The pneumatic post receiving station holds a pneumatic post transport cylinder which arrives in the pressure operation ready for removal in a give n position. There is a device operated by the cylinder to interrupt the drive air flow from a continuous blower such that further cylinders which are on the way to the station remain in the tube system in front of the station without drive. After removal the first cylinder is conveyed on by removing the interruption to drive air flow. The air flow interrupter consists of an electrically controlled magnetic valve closing by-pass air orifice, which allows the drive air to flow outwards from the transport tube or the blower connection air tube or interrupts or short circuits the drive air flow of the blower.

Title: Rotor with additional mass for resonance damping - is used in permit use of simple shaft profiles and reduces noise
Inventor: PAPST GEORG F
IPC: H02K7/04
Filed: 1975-06-07
Abstract: The application is mainly to small diameter machines of low power output where, particularly on four pole designs, mechanical oscillations of the rotor can generate undesirable noise levels. These mechanical vibrations may be damped by adding an extra mass in the form of a disc to the rotor shaft, and this method of damping also permits the use of plain cylindrical shafts thereby assisting in the reduction of manufacturing costs. In alternative design variations the additional mass may be attached directly to the rotor body. A reduction in noise level of 5dB may be produced.

Title: Twin piston pneumatic miners pick - piston linked to housing for one-way rotation, pistons threaded to form screw rotor pair
Inventor: PETREJEW ANATOLIJ M
IPC: E21B1/38
Filed: 1975-06-13
Abstract: Pneumatic pick for mines or construction work has a drill rotor, pistons with freewheel coupling and screw pair so as to divide the housing into action spaces. One piston strikes against the drill steel and the piston which works with the chuck holding the drill steel is kinetically coupled to the rotor. The second of the two pistons (3) is kinetically linked to the main housing (1) and is thus prevented from rotating relative to this in one direction. The screw pair (4) is placed between the two pistons (2, 3) and is made up of male and female threads. The piston linked through the freewheel coupling to the housing should comprise a central piston rod which forms a rotor pair with a head component, and a thread on the rod to form the screw pair with the other piston, whilst straight spline slots at the far end of the piston work with the housing during drilling.

Title: Cutting machine for blocks of foamed synthetic resin - has endless wire guided by template for accurate profiles
Inventor: EISELT GUENTER
IPC: B26D1/00
Filed: 1975-09-22
Abstract: A device for cutting blocks of foamed synthetic resin, esp. for cutting profiles of this and similar materials, has a cutting tool stretched across a frame pivoting on a carriage. The cutting tool is a familiar endless thread formed by twisting together a number of separate wires. This runs on guide and driving rollers at least one of which is coupled directly to a motor. The rollers are arranged in a "U"-shaped pivoting frame, lieing roughly in a horizontal plane, arranged on supports and able to pivot on an axis running through the centre of gravity of the frame, and parallel to the extension of the metal thread outside the frame. The supports are assembled on a moving carriage carried horizontally by guides on the base structure of the machine, so as to be displaceable transversely to the axis of the pivoting frame. Beneath the range of movement of the part of the wire outside the frame, there is a horizontal table for the material to be cut. The machine structure is low and allows a wide ranging motion to the cutter, which is easily accessible at any point. The twisted wire gives a clean cut and flat surfaces which can be glued easily and correctly in subsequent operations. Profiles can be cut with the smallest radii, since the wire can move in any direction vertically to its length.
Patent DE-2544548-A1 (DE)
Title: Battery charger control circuit - interrupts power supply when fully charged regardless of battery condition
Inventor: RIEDER KLAUS HARTWIG DIPL ING
IPC: H02J7/00
Filed: 1975-10-04
Abstract: The charging is supervised by an operational amplifier (1) whose inputs are bridged by a resistor (4) and whose inverting input is connected to a capacitor (5). Resistor and capacitor are in parallel with the battery (2). When the battery is charging its voltage is rising, hence a current is flowing through the resistor (4) to charge the capacitor (5), and there is a voltage difference between the amplifier input terminals and therefore also an output. When fully charged the battery voltage ceases to rise, the amplifier inputs become equal and it switches off thereby also switching off the battery power supply (20, 25, etc.). As operation depends only on steady battery voltage, or a predetermined minimum rate or rise, it is not dependent upon battery state. If, due to ageing, the battery voltage no longer reaches the nominal value the charging circuit is still interrupted when steady conditions obtain.

Patent DE-2616234-A1 (DE)
Inventor: KOENIG FERDINAND DIPL ING
IPC: H03L7/24
Filed: 1976-04-13
Abstract: This synchronizing device for electrical oscillators is used for indicating the position, for example of control valves, in redundant systems. The oscillators (Oi) exhibit a switching element (11) which changes from one stable state to the other when a comparison difference of two signals (20-26) changes sign. The oscillators are synchronized by a decaying signal (44) which is connected to the input of all switching elements (54) and is generated by a timing element (42, 43). The decaying signal of the fastest oscillator in each case causes the switching elements of all other oscillators in the system to switch prematurely. <IMAGE>
