Title: Security alarms in association with concrete structures
Inventor: LEIH MICHAEL PERCIVAL
IPC: G08B13/12
Filed: 1982-09-13
Abstract: A concrete structure, in particular a precast concrete wall (2), has a security alarm assembly (1,7) associated therewith for providing an alarm condition if an access aperture is formed through the structure or wall. The alarm assembly includes tangible conductors (1) on the structure or wall such that a conductor will be broken when an access aperture is formed. Various forms of attaching the conductors to the concrete structure and wall are envisaged, such as by adhesively securing them (at 3) to the outer concrete surface; embedding them during casting of the concrete; and thereby then through tubes cast into the concrete. <IMAGE>

Patent GB-2154467-A (GB)
Title: Medical humidifier
Inventor: MITCHELL VICTOR
IPC: A61M16/16
Filed: 1984-01-28
Abstract: A medical humidifier has an electrically or mechanically actuated valve (1) which is controlled by a temperature sensor (5) sited in a mixing chamber (4). By varying gas flow through two saturators (2) and (3) which are maintained at predetermined temperatures and recombining the product gas streams a single gas stream is produced with desired humidity and temperature. By virtue of this configuration the humidifier is able to respond rapidly to changing conditions and can give accurately determined temperature and humidity, immediately upon connection if the saturators are pre-warmed. The temperature of the gas stream emerging from the humidifier can, if required be elevated further by an independently controlled heater situated downstream of the mixing chamber. The operating temperatures of the humidifier can be adjusted to suit the application. <IMAGE>

Title: Television pick-up system operating with mutually differing a.c. voltage mains frequency and television field frequency
Inventor: VAN DE POLDER LEENDERT JOHAN
IPC: H04N5/217
Filed: 1985-10-09
Abstract: A scene illumination (L2FU) obtained with the aid of the a.c. mains voltage (Un) results in a picture signal to be produced line and field sequentially by a pick-up arrangement which on display shows annoying flicker phenomena. The phenomenon is caused by the difference between the mains frequency (FU) and the field frequency (FV). To prevent the annoying flicker phenomena, the pick-up arrangement is periodically operated for scene recording with a pick-up period (TO) per field period (TV) substantially equal to or an integral multiple of half the period of the a.c. voltage mains cycle (TU). During the remaining part of the field period (TV) there is a blocking period (TB1 + TB2). <IMAGE>

The comparators 60, 65, 70 discriminate between three signal levels provided at node 24 by processors 3 and 4. A yellow LED 67 is turned on in response to a high level at node 24 obtained when information from the trailer processor 4 is not available, e.g. due the tractor and trailer being uncoupled, absence of a processor 4 on the trailer, malfunction of the processor 4 or an interruption in the connection of processor 4 to node 24. If the device and light circuit are normal, an intermediate level is provided at node 24 and a green LED 69 is turned on. In the presence of a failure in the supply circuit of lamps 5, 6, e.g. due to an interruption in the circuit or burning out of a lamp 5, or 6, node 24 is at a low level and green LED 69 and red LEDS 72, 73 are turned on. <IMAGE>
