Abstract: 1,084,180. Photo-electric inspection of moving webs. BUCKBEE-MEARS CO. Oct. 6, 1965 [July 30, 1965], No. 42497/65. Heading G1A. Portions of a continuously moving web are sensed by an array of photo-cells which travel along with the web for the period of the test and then return to their home position prior to sensing a fresh portion of the web. Fig. 1 shows a continuously moving metal web 33 in which are formed T. V. aperture masks 31 comprising a multitude of miniature apertures which have been etched through the metal. The apertures are sensed for correctness in diameter by an array of five photocells 35 distributed over the mask area and carried on horizontal bars 36 of a square-frame 19. The frame is contained within a larger one 19 which becomes clamped to the web by a clamp 29 also Fig. 3 (not shown) when in the home position as shown and travels to the left on rollers with the moving web whilst the photo-cells sense the apertures and then releases the web on reaching the limit of its travel, after which it is returned to the home position by piston 28. Further photocells may be mounted on the other side of the web. During the return travel of the frame the array of photo-cells is re-aligned on the oncoming masks by the aid of a locating slot 42 adjacent each mask and two photo-cells 34a, b, which control the up and down movement of the inner frame on vertical guide rails 20 carried by the outer frame 18. The photo-cell 34c senses a second slot 43 during the return travel and primes a circuit to clamp the frame at every third mask. Buffer switches positioned at the two ends of travel of the frame have over-riding control of the clamping and unclamping. Another photo-cell 39 provides a safety device in that it prevents clamping of the photo-cell senses a mask, thus indicating a false location of the array of photo-cells.

Abstract: 1,143,647. Valves. HANSA METALLWERKE A.G. 15 Aug., 1966, No. 36450/66. Heading F2V. [Also in Division F4] In a compression-condensation refrigeration system which is defrosted by operation of a changeover valve 1 in the compressor outlet and suction lines, a valve assembly 16 is located between the condenser 9 and evaporator 11 and has connections to a receiver 25 and dryer 26, and to a point between an expansion valve 14 and the evaporator inlet, the valve assembly being such that during defrosting the valve 14 is by-passed and the direction of refrigerant flow through the receiver 25 and dryer 26 is the same as in normal operation. During normal operation the pressure difference between valve connections 17 and 21 to the condenser and evaporator respectively acts on check valve 36 to allow flow from the condenser to the receiver, and a spring loaded check valve 40 closes a port 38 to allow flow from the dryer to the expansion valve. When the valve 1 is reversed to initiate defrosting, the expansion valve 14 closes automatically in response to the change in evaporator pressure and the lower pressure obtaining in the condenser allows the check valve 40 to open causing flow from the dryer to the condenser. The reversed pressure difference between the evaporator and condenser acts on the check valve 36 to allow flow from the evaporator through the connection 21 to the receiver. The check valve 40 has a stem 47 which is freely movable in a bore 48 of a valve 43 which may be adjusted by screw action to vary the maximum flow cross-section of the port 38. The changeover valve 1 is operated by a solenoid 13 which is controllable by hand or by a time switch or by reference to the amount of ice on the evaporator. Alternatively the change-over valve may be arranged for direct manual operation.

The target of an image pick-up tube comprises an array of P-N junctions arranged in a pattern with axes which do not coincide with the scanning axes; this equalizes the probability of beam impingement in each scanning line and thereby reduces noise. The target may comprise an N- type silicon substrate covered on one side by an anti-reflective coating and on the other side by a layer of SiO 2  through which a plurality of holes are etched and P-type material diffused into the exposed substrate. Preferably a metallic coating is formed over each P-type area and extends over the adjacent insulating area; this reduces the insulating area on which charges may be deposited by the scanning electron beam and thereby reduces noise. In Fig. 6b the metal coatings 30b are hexagonal and the junctions are arranged along axes X 3  and Y 3  inclined at 30 degrees to theline scanning direction; the P-type areas are diffused through 22À6 micron diameter holes in the insulating layer and are spaced 40 microns apart, and there is a 5À3 micron spacing between the conductive coatings 30b. In a modification, Fig. 6a (not shown), the P-type areas are arranged in a rectangular array and are covered with square conductive coatings. Circular P-type regions with no conductive coatings arranged in a rectangular array or in the array shown in Fig. 6b are also described (Figs. 4a and 4b, not shown).

[Also in Division E2] An automatic safety device in a vehicle comprising control means 18 for opening and closing doors, a two-way manual emergency switch 8, door jamb switches 7, an automatic brake control 31, a vehicle-speed sensitive switch 23 and signal means 12, 33, comprises a control unit incorporating two multiple-contact relays 1, 2 and a two-contact adjustable time-delay relay 3 responsive to disconnection of a terminal f of its energizing coil 3e from earth, the other coil terminal d being connected to a voltage source, suitable connections being provided between the control unit and the signal means and control switches and other means. In operation when the vehicle slows to e.g. below 2 m.p.h. the switch 23 closes operating signal light 12 until a door unlocking push button 11 is operated thereby energizing the coil 1e and operating the first relay 1, putting out the light 12 and connecting the door opening switch 16 to the power source through the relay arm 1a. Closing of the switch 16 energizes one or more electromagnetic door valves 18 to open the doors. As a first door opens a respective jamb switch 7 is closed thereby energizing the coil 2e to close the relay 2 and hence energize an automatic brake valve 31, a brake indicator light 33 and the coil 3e of the relay 3 through relay contacts 2a and 1c and switch 23. The doors are closed by opening switch 16 and opening of the jamb switches 7 de-energizes the relay 2, thereby opening contacts 2b, to de-energize the relay 1 and hence illuminate the light 12 again, and 2a, to disconnect terminal f of the relay 3 from earth which actuates the time delay 4. The two lights 12, 33 together denote operation of the time-delay and that the brake valve 31 and door switch 16 are still connected to the power source through the relay contacts 3a and 3c. If during this period a door sensitive-edge was actuated a door jamb switch 7 would then be closed to re-energize the relays. Normally at the end of the time delay the brakes are released and the vehicle may proceed. The two-way switch 8 permits energization of the switch 16 through a conductor 14 should there be a failure in the relays or associated components.
