Abstract: 392,928. Valve circuits. LYONS & CO., Ltd., J., Cadby Hall, Kensington, DOUGLASS, P. G., 12, Auriol Mansions, West Kensington, and PASSMORE, C. R., Ardneil, Oakleigh Park, Whetstone, all in London. Nov. 23, 1931, No. 32411. [Class 40 (v).] A time-lag device, which mav be used for keeping a door open for a predetermined period after a photo-electric cell has been shadowed by a passing person, is of the kind in which, as described in Specification 353,776, the duration of the effect is determined by the leaking away of a charge from a condenser. According to the invention the condenser is conductively in circuit with the controlling valve. The door-opening mechanism is controlled by relay 1, which remains de-energized so long as photo-electric cell 7 is illuminated by lamp 10, since the unidirectional current via A, 4, 6, 7, b puts a negative charge on grid 5g, and grid 3g also becomes sufficiently negative to de-energize magnet 1. When the cell 7 is shadowed, however, it becomes non-conducting, the small condenser 8 discharges, valve 5 passes current, and condenser 4 acquires a charge which positivizes grid 3g and causes energization of the door-opening relay 1. When the cell 7 is re-illuminated, the charge on the large condenser 4 slowly leaks away through the cell and the resistance 6. After an interval determined by the constants of the circuit, relay 1 again releases and the door closes.

Title: Improvements in or relating to weighing apparatus
IPC: G01G13/30
Filed: 1934-11-10
Abstract: 445,950. Automatic-feed weighers. MAATSCHAPPIJ VAN BERKEL'S PATENT NAAMLOOZE VENNOOTSCHAP, and DUYN, A. VAN, 33, Boezemsingel, Rotterdam, Holland. Nov. 10, 1934, No. 32444. [Class 143] An apparatus for weighing out predetermined quantities of liquids or gases and in which the flow is cut off electrically when the predetermined load has been reached, comprises electric contacts which are relatively movable in separate planes and relatively movable into and out of the same path of movement so that after contact occurring between the contacts in the same path they can move relatively to occupy their different planes and so be capable of free relative movement, one of said contacts being mounted on a load - influenced member such as the pointer and the other being adjustable with reference to the pointer. When an empty receptacle 6, Fig. 1, is placed on the platform 2, the pointer 4 is displaced over the weight dial 5. A hand wheel 10 is turned to adjust the zero of a tare chart 3 to the new position of the pointer, and the cock 7 (which tends to close under spring pressure) is turned by hand to its fully - opened position wherein it is retained by a pawl 18, Fig. 3, cooperating with notches 16, 17 and controlled by spring- pressed plungers 22 , 23. When the major part of the charge has entered the receptacle a contact 40 on the pointer touches a contact 38 on the tare chart, this contact having been moved into the path of the contact 40 by an electromagnet 36 carried on the chart and energized on opening the cock 7. Closure of the contact 38 energizes electromagnets 26, 27 which then release the plunger 23. The cock 7 turns under the influence of its spring (pressing back the pawl 18 and plunger 23) until the second notch 17 engages the pawl which is prevented from further releasing movement by the locked plunger 22. The movement of the plunger 23 de-energizes the electromagnet 36 and the contact 38 is consequently withdrawn from the path of the pointer 4. The reduced flow continues until the weight is made up, whereupon the pointer contact touches a second contact 39 associated with a second electromagnet 37 secured to the tare chart, and releases the upper plunger 22, the cock 7 then turning to the closed position, the action being similar to that in connection with the plunger 23. The contact 39 may be adjustable on the tare chart so that different predetermined loads may be weighed.
