Title: Door having a spring door closer
IPC: E05F1/06
Filed: 1978-06-26
Abstract: This invention relates to a door (1) having a closing device and arranged for movement about a substantially vertical axis. The closing device comprises two members (18, 22) urged towards each other by resilient means (26), one member (18) provides a cam path (19 extending both axially of and co-axially with the door axis. A rolling body (20) is mounted on the other member (22) to roll along the cam path. One of the members (18) remains stationary while the other (22) moves with the door. One of the members (22) is displaceable substantially parallel to the door axis against the resilient means (26). Opening of the door (1) causes the rolling body (20) to roll along the cam path (19) and one of the members (22) to be dis- placed against the resilient means (26) when the door (1) is released, the resilient means (26) urges the rolling body (20) back along the cam path (19) and the door (1) closed. The door (1) only moves about the axis and not along it. <IMAGE>

Patent GB-786032-A (GB)
IPC: G06F7/38
Abstract: 786,032. Digital electric calculating apparatus. DIRKS, G. June 23, 1950 [Oct. 1, 1948], No. 37213/54. Divided out of 786,021. Class 106 (1). An arithmetic unit comprises a cathode-ray tube, means for giving the beam two deflections in accordance with respective digit values, and means whereby the resulting position of the cathode-ray is detected and gives rise to signals representative of the result of the computation in the same scale. The values of resistors 7<SP>0</SP> ... 7<SP>9</SP>, 11<SP>0</SP> ... 11<SP>9</SP> are chosen to allow current through a resistor, when its associatd gas-discharge tube 3<SP>0</SP> ... 3<SP>9</SP>, 4<SP>0</SP> ... 4<SP>9</SP> is triggered, proportional to the digit represented by its tube. Thus voltages developed across common loads 6 (for the tubes 3<SP>0</SP> ... 3<SP>9</SP>) and 10 (for the tubes 4<SP>0</SP> ... 4<SP>0</SP>) will he proportional to two digits entered by triggering a tube in each set. The application of the voltages to the plates of a cathode-ray tube 1 causes the beam to be deflected to a point on the screen representing (in the example shown) the sum of the two digits. There are two target elements at each result position, and elements having like values are connected together and coupled to a result tube 5<SP>0</SP> ... 5<SP>9</SP> which is triggered by a voltage developed by secondary-emission current. The tens digit which, in the case of addition, cannot be greater than 1, is detected by a tube 15 which performs carryover by increasing the current in the load 6 by unity in the next denomination. Other arithmetical tables can be employed, and the two digits may be arranged to cause deflections in the same direction or in a spiral fashion. The secondary emission spots may be replaced by anode elements for direct cathode-ray switching. Alternatively, photo-cells may be used to detect the illuminated result spot on a fluorescent screen. Instead of employing selectively operative discharge tubes and resistors to represent digit values, electromechanical relays may be used.

Title: Apparatus for clarifying water
IPC: B04C5/30
Filed: 1980-10-10
Abstract: Apparatus for clarifying water by the separation of and removal therefrom of undissolved solids includes four chambers A, B, C, D separated from each other by weirs 5, 6 and 7. The water to be clarified is introduced into chamber A and extracted therefrom by a pump 10 and passed to a vortex or cyclone separator 11. This discharges clarified water into chamber B from which water overflows into chamber A. Water from chamber B is passed by pump 14 into a pair of vortex or cyclone separators 15 connected in parallel and discharging clarified water into chamber C from which water overflows into chamber B. Water from chamber C is extracted by pump 18 and is introduced into a pair of vortex or cyclone separators 19 connected in parallel and discharging clarified water into chamber D from which water overflows into chamber C. Thus there is a continuous overflow of water from chamber D into chamber C from chamber C into chamber B and from chamber B into chamber A. The water is progressively clarified as it is recirculated by the pumps 10, 14 and 18 and so sufficiently-clarified water is extracted by pump 22 from chamber D. <IMAGE>

Title: Physical Variable Monitor
IPC: G06F17/40
Filed: 1980-12-23
Abstract: A monitor receives consecutive digital signals (at 11) representative of the value of a variable such as temperature, voltage, current or pressure, at predetermined time intervals, and temporarily stores the digital signals (at 13). A central processor unit (14) calculates, under control of an EPROM (15) the mean of a number of consecutive stored signals and compares the mean with a previously calculated mean to determine whether the calculated mean differs from the previously calculated mean to more than a predetermined extent. A clock (16) is provided, and a storage means (13) stores the calculated mean signal when it so differs together with the clock signal. The task of monitoring a physical variable, for example the progress of a number of batteries under charged, is thereby made more efficient. <IMAGE>
