Title: Circuit for combining signals - has input signals applied across transformer secondary windings and output signal obtained from primary winding
Inventor: LOTZ ALFRED
IPC: H03K19/007
Filed: 1974-12-24
Abstract: The circuit is for logically combining several AC input signals to provide an AC output signal (A1). The input signals are applied to separate input terminals and connected to the secondary windings of a transformer (T) via rectifying means, the rectified input signals providing the individual control potentials for a transistor oscillator. The pulse output voltage of the latter is applied via an amplifier (V5) to the output. For converting static signals into a dynamic signal the first static input (E1) is brought to the base potential of the transistor (V4) in the oscillator circuit via a static Null signal, the supply voltage for this transistor (V4) provided a further static input (E2), which also determines the operating point of the transistor (V4) via a voltage divider.

Title: Ultrasonic copying of internal structures - applicable to solid, liquid or solid and liquid objects and allowing testing of pulse properties in copy medium
IPC: G01H3/12
Filed: 1975-05-06
Abstract: Internal structure of 3-D solid and/or liquid object is reconstructed, e.g. for echo encephalography, by emitting ultrasonic waves into the object and copying the object symmetrically in layers with respect to properties such as damping capacity, absorption capacity, amplification capacity, refraction capacity etc., using a recursion process. The object is activated for a given period, so that in the "i"th stage a coherent monochromatic wave pulse, which is produced outside the object and passes through the "i"the layer of the object during the period, produces two further pulses containing information on absorption capacity and rate of diffusion of waves in the layer. The image layers in the copy medium have the same refraction and absorption properties as corresponding layers in the object.

Title: Machine for mitring both ends of length of wooden workpiece - uses hydraulic slide and then friction belt to bring wood to tool
Inventor: LANG KARL
IPC: B27F1/00
Filed: 1975-11-06
Abstract: The length of workpiece is first moved by a hydraulic slide up to a stop that maraks the first cutting position. The slide holds it while a corner is rounded (to prevent subsequent splitting) and a circular cutter advances obliquely to cut the leading-end mitre, and withdraws. The slide moves the piece forward until the friction band takes over its transport, then returns for the next piece. Meanwhile the friction band, which is ata the side of the wood, takes it forward as far as a stop, and a bar moves across to clamp the wood against the friction band. Again a corner is rounded, and a circular cutter moves obliquely backward to cut the trailing-end mitre, and withdraws. The friction band can be fitted with two stops, to be used alternately, so that the four sides of a picture frame can be cut in order.
