Title: Sealed electric motor for use in wet conditions - has shaft connected to magnet inside sealed casing with driven magnet mounted on output shaft outside casing
Inventor: FRANCOISE
IPC: F04D13/10
Filed: 1980-04-14
Abstract: The pump unit which may be used in a mine shaft to pump out stale air includes a motor housed in a waterproof container. A solar battery (4) on the surface above the mine shaft provides a direct current which is fed via conductors passing down the shaft to the motor (2). The motor is sealed inside a casing (1) to prevent the ingress of water. The rotor of this DC motor is connected by a shaft to a rotating magnet assembly (7) near the top of the sealed casing. In the top of the casing there is a cylindrical recess which receives a second magnet (8) mounted to rotate on a vertical shaft. There is a magnetic coupling so that rotation of the motor drives the second magnet (8). This in turn drives a fan (10) in the upper part of the mine shaft to circulate air.

Title: Sensor for milk temp. measurement in tank - is located in pipe from reservoir to tanker lorry and provides output when flow is validated by flow sensor
Inventor: GROUX PIERRE
IPC: G01D1/12
Filed: 1980-12-23
Abstract: The appts. has a temp. sensor located in the outlet pipe from a storage tank through which liquid is pumped to a tanker lorry. The sensor is connected to a current to voltage converter (15) to provide a voltage proportional to temp. A resistance detector (17) is connected to a sensor in the outlet tube to measure the electrical resistance of the liquid to signal its presence or absence. This signal is applied to a timer (21) which allows the converter to measure temp. after the timer period. The converter output is applied to a maximum valve memory (22) containing a capacitor (26) the discharge of which is prevented by diodes (27). A galvanometer (23) displays the temp.

Title: P-codes-analog converter - has code development unit input as inlet while output feeds gates
Inventor: STAKHOV ALEXEI PETROVICH
IPC: H03M1/00
Filed: 1981-01-14
Abstract: Simplified meterological control of the P-code/analog converter is achieved with the usage of code presentation ambiguities in the same digit to enhance the reliability The gates corresp. to the number of digits in the code have their output connected to the relevant input of reference analog magnitudes adder which are proportional to the weights of P-code digits. The adder output forms the converter output feeding the multidigit input of the gates. The converter operates either in the regime of meterological control or in the regime of direct conversion following the first regime. The switching is carried out with a signal fed to controller (9) the command of which inserts a binary 'I' into the high order digit of code development unit (5). The output of each gate (I) is connected to the reference values adder (2) which can be made as a source of weighted currents. The difference of output levels of the adder is detected by the discriminator (6) and the type of development of code is determined by unit (8) while the distorted digits numbers are stored in block (7). The first multidigit input of the code development unit (5) acts as the converter input while the second input is connected to block (7) made as a register. When the reference value cannot be used to provide the output analog value it causes a 'non- construction' failure. If it results in an output analogue value which is not proportional to the weight of the code digit 'detuning'type failure occurs.

Title: Anti-dazzle vehicle headlamp - has two part parabolic reflector directing large component of beam below horizontal axis
IPC: F21V7/00
Filed: 1981-03-19
Abstract: The anti-dazzle headlamp includes a bulb mounted at the centre of a small reflector. This is directed back into the lamp housing and inclined slightly upwards. Light from the bulb and its small reflector strikes one of two parabolic mirror sections. Light leaving the bulb in an upward direction strikes the upper parabolic reflector, whilst light leaving the bulb in a downward direction reflects from the lower parabolic mirror on to the upper mirror before leaving the lamp. This arrangement creates an additional component to the part of the beam which is directed down from the horizontal axis of the lamp beam. The bulb is supported on the side nearest to the front of the lamp housing, behind the lamp cover glass.

The chambers are pref. mounted removably on top of the tunnel. The cryogenic gas employed in the process is pref. carbon dioxide. The conveyor band is pref. stainless steel and the tunnel and chambers are insulated with expanded polyurethane. The process is for freezing small quantities of a variety of food prods. to be packed together for controlled temp. distribution to individual customers with domestic type frozen storage cabinets. Making up this type of mixed package is prohibitively expensive for producers equipped only with industrial plate freezers and blast freezing tunnels.
