Title: Reactor charge machine fuel grab lifting mechanism - is hydraulic ram giving reduced height and weight
Inventor: HOFFMEISTER BERNHARD
IPC: G21C19/16
Filed: 1974-05-31
Abstract: A lifting mechanism for the grab of a nuclear reactor charge machine for handling fuel elements or control rods comprises a hydraulic piston-cylinder unit with piston rod. one or other moving component (cylinder or piston rod) engages into the hollow top of the grab by a coupling device, while the other component is mounted on a support attached to the charge machine carriage. In the preferred arrangement, the piston rod is connected to the charge machine support member by a two directional pivoting hinge, and comprises a duct for fluid communicating with the space inside the cylinder and outside the piston rod; the lower end of the cylinder is connected by a two directional hinge to the grab. The preferred hydraulic fluid is water. This water pref. circulates in a closed system consisting of the cylinder space, the duct through the cylinder rod, a connecting line and a displacement chamber of the piston-cylinder type, in which the piston is itself actuated by a different pressure fluid on the opposite side. As compared with a hoisting mechanism comprising cables pulleys etc., the hydraulic arrangement results in a more compact system, a lower centre of gravity, reduced weight and smaller space requirement. It is not possible for contaminated water from the reactor to drip onto the platform of the charge machine.

Title: Dry filter pref. for mine ventilation systems - having pneumatic dust removal system agglomeration device and cyclone
Inventor: HOELTER HEINZ
IPC: B01D46/48
Filed: 1974-06-14
Abstract: The parent patent describes a dry filter for mining applications employing box construction and built as a packaged unit. The floor of the filter chamber is inclined and perforated and compressed air blown through it to fluidise and transport the collected dust is simultaneously used to vibrate the filter to shake the dust from the filter bags. The air/dust mixture is drawn out through and by a jet-ejector into whose high velocity region water is sprayed to agglomerate the dust prior to sepn. in a cyclone. In this addition, the filter is vibrated and/or isolated from the main exhaust fan (for the air being filtered) by an injector nozzle, whilst a reverse air blast is generated in the region of the exhaust duct. The auxiliary inject nozzle temporarily nullifies the suction on the filter elements exerted by the ventilation fan thereby assisting, or rendering unnecessary, the vibration of the elements for dust removal.

Title: Loudspeaker automatic volume control - adjusts to background noise level and has delayed volume reduction to avoid volume pulsing
Inventor: SUEHSMUTH GUENTER
IPC: H03G3/32
Filed: 1975-01-16
Abstract: The automatic volume control for loudspeaker automatically adjusts to the level of background noise. A signal (UP) representing the product of an input voltage (US) and a second voltage (UF) is formed and added to the original input voltage to form a fourth signal (UL). The product signal (UP) rises rapidly as the level of interference increases and falls slowly as the interference level drops. The fourth signal is used to drive the loudspeaker. The advantage of delaying the drop in volume to its 'normal' level lies in preventing unpleasant volumen fluctuations in response to intermittent interference repeated at short intervals.

Title: Transistorised telephone transmission system - using single wire circuit has earth return path and pulse position channel selection
Inventor: SAHEB EYAS DJAWAHER
IPC: H04J99/00
Filed: 1975-03-26
Abstract: The transmit/receive circuits use the carrier line telephony principle with one leg of the circuit connected to earth as a return path. Up to one hundred speech channels can be accommodated. The carrier in the form of unsmoothed half-wave pulses of a sinusoidal waveform. Each speech channel occupies a narrow pulse positioned at any point on the leading or trailing edge of the carrier half-wave. In the receiver, the carrier is converted to a square-wave and further to a sawtooth. A transistor flip-flop produces pulses which are further converted to synchronised pulses and mixed with the carrier waveform. Further circuits demodulate the selected pulses to extract the audio information which is amplified and fed to a headset or loudspeaker.
