Title: Pressure-demand Breathing Apparatus With Automatic Air Shut-off
IPC: A61M16/00
Filed: 1979-07-17
Abstract: A face mask 16 is connected to a source 2 of breathing fluid through a pressure-demand regulator 14 and a supply line 6, 10. The regulator 14 admits breathing fluid to the mask 16 on demand and maintains a positive pressure within the mask at all times to prevent inflow from the surrounding atmosphere. The regulator 14 has a flow capacity considerably greater than that normally required, even when gasping or breathing heavily. An automatic shut-off device 12 in the supply line 10 upstream of the regulator 14 permits the peak flow of a predetermined breathing requirement but is responsive to abnormal flow conditions, as for example where the mask 14 is removed from the wearer, to close the supply line 10 and thereby prevent wasting of the air breathing fluid supply. The apparatus can be manually reset to normal operation and will reset itself after the mask is repositioned on the wearer. <IMAGE>

Title: Regulating a slip-ring induction motor
IPC: H02P1/36
Filed: 1980-05-01
Abstract: Three-phase slip-ring induction motors with liquid starters 3 are frequently used as drives for winders. The position of the liquid starter 3 is controlled by means of a position control device 4 as a function of the respective desired resistance value. However, such adjustment of the starter 3 can lead to an actual resistance value which, as a result of the parameters of the starter 3, deviates to a considerable extent from the desired value. To obtain the actual resistance value required, therefore, a rotor current regulator 17 feeds the position control device 4. The product of a signal which is proportional to a desired resistance ie motor current set at 16 and of an actual value signal of the slip of the motor as derived from the measured induction motor speed are supplied to the rotor current regulator 17. <IMAGE>

Title: Control device for a heating apparatus with time-dependent lowering of heating characteristics
IPC: G05D23/24
Filed: 1980-12-16
Abstract: In a control device for a heating apparatus with adjustable heating characteristic (set point) in which, with respect to a heating characteristic set for first periods, the heating characteristic is lowered during second, more particularly nightly, periods, the lowering of the heating characteristic is cancelled during said second periods if a room temperature comparator detects a lower temperature than a set minimally desired temperature in a room which is temperature controlled. Operation is also slightly influenced by the exterior temperature during each of the said periods. As shown, the outputs of a boiler water temperature sensor R2 and a room temperature sensor R4 are summoned and compared in OA with a reference value determined by resistors R5-R6 and R11-R13. In the daytime, R13 is short-circuited by relay contact S; but at night a clock KL de-energizes the relay so that the temperature set point is lowered. However, if room temperature comparator RTV detect a temperature below a desired minimum, the relay is again energized to restore the higher set point, to prevent freezing. <IMAGE>

Title: Image digitising system
Inventor: DASKALAKIS COSTAS
IPC: G06T5/40
Filed: 1982-05-21
Abstract: An image is scanned by a TV camera 9 and the resultant signal digitised in an analogue to digital converter 12 the output of which represents the measured intensity of each picture element of the image. The values relating to selected lines may be captured in a line store 13. Alternatively the number of picture elements of a selected intensity may be counted during the count of a scan in a level counter 14, using a look-up table 15 as a mask to select the desired level. After all levels have been similarly counted the resultant histogram is modified by mapping each intensity into a new value with a smaller number of bits in such a way as to tend to equalise the number of picture elements in each new level. The new values are loaded into the look-up table 15 and in subsequent scans the measured intensities are converted into the new values, which may be displayed on a monitor 16 or captured in the line store 13. <IMAGE>
Patent GB-2127534-A (GB)
Title: Gas fire
Inventor: SMITH KENNETH GEORGE
IPC: F24C1/14
Filed: 1982-09-17
Abstract: A box-radiant gas fire 15 has an array of burners which direct combustion products into radiants 16. These combustion products are then made to pass into the inlet chamber of a heat exchanger having two separate parallel passageways which extend from the inlet chamber to an outlet which communicates with the atmosphere; thus the combustion products can escape from the fire through the exchanger only after being divided into two separate portions as shown by the arrows in full line. Each passageway is surrounded by a common conduit 13 along which clean, initially cool, air is passed in a direction opposite to that of the combustion products flow. Thus the heat is transferred from the combustion products to the air and the latter, once warm, is then fed into the room containing the fire. In another form, the arrangement of passageways and conduits is such that the flow of combustion products is substantially parallel to that of the convection gases.
