Title: Recording method for a number of voltages - which are recorded as a function of time on a common chart
Inventor: BACHEM CHRISTIAN DR
IPC: G01R13/10
Filed: 1973-09-14
Abstract: All voltages are recorded periodically by points by a common recording device, whose possible working point is periodically moved over the whole chart width. It is operated by the equality signal of comparators whose outputs are connected together. Each voltage to be recorded is applied to a respective comparator first input, and a voltage periodically crossing the whole measurement range is applied to its other input. This voltage is synchronised with the recording device periodic change of its working point. The common recorder is frictionally connected to a potentiometer wiper from which the reference voltage for the comparators is collected. A strip lies on the charge and covers it whole width. It carries a large number of insulated metal points, to which the marking signals from comparators are applied through a commutator running synchronously with the reference voltage of the comparators.

Title: Item pneumatic tube conveyor - has emitters detecting slug passage controlling overflow valves at each section
Inventor: KOWANOW PAWEL WASILEWITSCH
IPC: B65G51/08
Filed: 1973-10-06
Abstract: Overflow valves discharge the compressed air temporarily at the loading and unloading stations to allow the transport slugs to be halted there, and work under the control of emitters after each station detecting passage of the slugs, which cause them to open and close accordingly. The overflow valves are so spaced along the tube that they divide it into sections in which during movement the slug or train of slugs are. The number of such sections is at least one more than the number of slugs or slug trains in the system at one time, and individual emitters are mounted downstream of each valve. These transmit signals to open the valve in the next section and close that in the previous one.

Title: Hydraulic line leak protection for dredger - monitoring piston actuates main piston to close line
Inventor: MESSMANN JOSEF
IPC: F17D5/02
Filed: 1974-04-01
Abstract: A load handling machine such as a dredging machine has a safety valve incorporated in the line to a hydraulically operated device such as a jib or shovel, in order to protect the device in the event of a leak in the line. The valve is located between two throttling points at each end of the line to be safeguarded, one of the throttling points being a chamber between the double ended valve member. This member is actuated by a monitoring piston at one end of the valve, that in the event of a fall in pressure the monitoring piston moves the double piston which blocks the main line.

Title: Stop watch or timer restraint mechanism - uses two congruent wheels with meshing peripheral teeth of two wheels
Inventor: ULMER MANFRED
IPC: G04B15/06
