Title: Wire bundle binder mechanism - automatically adjusts arm working width and binder wire quantity to match bundle diameter
Inventor: FASHOLZ HANNS
IPC: B65B27/10
Filed: 1977-02-12
Abstract: The mechanism is for binding bundles of wires and particularly concrete reinforcing bars. The working width of the binder arms (8, 8') and the amount of binder wire (13) fed forward are automatically adjusted to match the diameter of the bundle (10). There can be clamping arms (50a, 50b) each with a concave jaw (51a, 51b) acting against the wires or bars, and to which a metering cylinder is coupled. This dispenses a quantity of oil used for a motor (29) driving the binder arms. When the clamping arms have compressed the bundle the distance between the binder arms is the sum of the bundle circumference and a doubled value to allow for twisting of the binder wire.

Title: Pressure gradient measurement in conductive pipe - having conductive cylinder surrounding and insulated from pipe
Inventor: MOSER WERNER DIPL ING
IPC: G01L9/00
Filed: 1977-10-26
Abstract: Appts. for electrical measurement of the pressure gradient in an electrically conductive pipe contg. a liquid or gas comprises a rigid electrically conductive hollow cylinder surrounding the pipe, and between cylinder and pipe an insulating layer which elastically takes up radial expansion of the pipe. These elements either directly form a capacitive - pick-up or coact with inductive pick-ups attached to the hollow cylinder. The cylinder pref. consists of two half rings, while the insulating layer also consists of two half rings and is applied to the cylinder in the form of a coating of plastic e.g. PTFE. Where inductive pick-ups are used, these each consist of a split ferrite core with a winding and are embedded in the cylinder by a hard casting compsn. Pressure is thus measured without affecting the liquid or gas or its flow conditions and without reducing operational reliability.

Title: Normal frequency generator with phase control circuit - has pulse absorbing gate mounted between VCO and programmed counter
Inventor: TANIZCE TOSHIO
IPC: H03L7/18
Filed: 1978-12-20
Abstract: The phase control circuit compares the phase of an output frequency of a frequency divider with that of an output frequency a programmable couter, in order to generate a reference signal. Thus the phase comparator detects a phase difference which is then integrated by a low-pass filter in order to be converted into a corresponding d.c. voltage output signal. This output signal is then fed to a voltage controlled oscillator for its excitation at a frequency corresponding to that of the d.c. voltage output signal. Between the oscillator (6) and the programmable counter (4) is mounted a pulse absorbing gate (7). The output pulses of the reference signal generating frequency divider (2) are counted so that the gate is closed during each period of the output pulses of the oscillator during a time interval of the frequency divider.
