Title: Improvements in and relating to devices for indicating the level of an electrically conducting liquid
Inventor: BLAKE LESLIE REGINALD
IPC: G01F23/24
Filed: 1956-05-08
Abstract: 856,004. Pressure gauges. BRITISH THOMSON-HOUSTON CO. Ltd. May 2, 1957 [May 8, 1956], No. 14262/56. Class 106 (2). [Also in Group XXXVI] A device for indicating the level 2 (Fig. 3.) of an electrically-conductive liquid in a tube of conductive material comprises a member M slidably mounted on the tube and carrying three contacts c1, c2, c3 which touch the tube, the portions of the tube between c1 and c3, and between c2 and c3, which are of equal lengths, having resistances R1, R2, respectively, and being connected with two resistors R3, R4 of equal values in a bridge arrangement, a D.C. voltage V being applied between the ends of the tube and a galvanometer G being connected between contact c3 and the junction of R3 and R4. Maximum deflection of the galvanometer needle occurs when contact c3 is adjacent the level 2. In an embodiment (not shown) for use with A.C., contacts c1 and c2 are connected to opposite ends, and the contact c3 to the midpoint of the primary of a transformer, two secondaries of which, each inductively coupled to one half of the primary, are connected in series opposition in a circuit including a voltmeter. Alternatively, a pair of separate, preferably identical, transformers, can be used. The difference in the levels of liquid in two tubes T 1 , T 2  (Fig. 6), of a manometer, is indicated on a linear scale 12 by a pointer 8 mounted on a floating pulley 7 to which half the algebraic sum of the movements of members M1, M2, is transmitted by a cord 4, the sense of the displacement imparted by M1 being changed by passing the cord 4 over a fixed pulley 13. Fig. 1 (not shown), depicts a conventional manometer comprising a conductive U-tube containing conductive liquid, the resistances of each half of the U-tube being connected in a bridge circuit to determine the level difference of liquid in the two limbs of the tube.

Title: Improved thermostatic electric switch for oven control
IPC: H01H37/36
Filed: 1946-05-14
Abstract: 611,951. Supply systems for heating resistances. CONSTANTINE, W. W. (General Motors Corporation). May 14, 1946, No. 14511. [Class 38 (iv)] [Also in Group XXXVII] Three heating elements 22, 23, 24 in an oven are controlled selectively by a thermostatic switch comprising three pairs of contacts 28, 29, 30 actuated simultaneously by a diaphragm 27, the contacts 29 having an insulating barrier 93 normally interposed between them. The diaphragm 27, connected by a tube 26 to a phial within the oven, acts on a triangular plate 60 supported by a leaf 61 to rest on a knife-edge 69, the lower end 65 of the plate acting on a -tension spring 53. The moving  contacts 28, 29 are mounted on members 42, 43 bridging the free ends of trifurcated plates 41, the middle legs of which are clamped at 45, 451 by conductive rivets connected to live supply lines L<SP>1</SP>, L<SP>2</SP>. The moving contact 30 is carried by a conductive extension of the plate 451. The spring 53 is secured to an insulating bar 51 which carries the plates 41 and thus holds the middle legs thereof in compression, moving with a snap-action from the normal " on " position when the diaphragm 27 moves the spring 53 to the left, Fig. 6. Setting of the diaphragm 27 is varied by a knob 15 rotating a threaded rod 17 in a fixed boss 13<SP>1</SP>, thereby moving a plate 10 about its lower edge. The knob 15 also drives a pin 81 which rests in a spring latch, Fig. 3 (not shown), when the diaphragm is compelled to open the contacts irrespective of the oven temperature. When the knob 15 is rotated beyond the high temperature setting to the " broil " position, the pin 81 acts through levers to raise the insulator 93 and also to hold the moving contact 30 open so that the lower heater 22 is disconnected and the upper heaters 23, 24 are connected between line L<SP>1</SP> and neutral line 37 respectively and line L<SP>2</SP>, Fig. 9 (not shown). If the knob 15 is now rotated back to a temperature setting, " preheat " conditions exist with all the heaters on full, until the thermostatic control opens the contacts and allows the gravity-controlled insulator 93 to fall and prevent reclosure of the contacts 29, so that, when subsequently energized, the heaters 28, 29 are connected in series between live and neutral lines L<SP>1</SP>, 37. The switch may be used on a two-wire circuit with an oven having only the two heating elements 22, 23.

Title: Improvements in or relating to carburetters for internal combustion engines
IPC: F02M69/00
Filed: 1941-11-14
Abstract: 553,349. Carburetters.-BENDIX AVIATION CORPORATION. Nov. 14, 1941, No. 14699. Convention date, Jan. 13. [Class 7 (iii)] The fuel supplied by a pump 30 through passages 42, 47, 48 to a nozzle 51 in the airintake pipe 10 is controlled by a by-pass valve 40 actuated by diaphragms 81, 82, the former of which is subjected to differential pressures in the air intake 22 and in a venturi 24, and the latter to the difference in pressure between the unmetered fuel in the pump delivery 34 and the metered fuel in passage 47. The airflow and the fuel flow thus act in opposite directions on the diaphragms and the valve 40. This balance is somewhat upset for idling, by a light spring 94, which tends to close the valve 40 so as to provide a richer mixture. The action of the air pressures on the diaphragm 82 is varied according to altitude by a valve 106 connected to a capsule 107. If the valve 106 should stick at high altitudes, too lean a mixture is prevented by the opening of a valve 1110 effected by an excessive movement of the pilot's control 57. Normal movements of this control adjust a needle 56, in the fuel passage 46, and a further control valve 65 is opened at higher powers by the action of the fuel on a diaphragm 67. Another restriction of the fuel passage is caused by a valve 61 when the throttle 15 is closed. A disc 60 on the valve 56 shuts off the fuel when the engine is stopped. The by-pass slide valve 40 may be replaced by a balanced poppet valve. Specifications 523,895, 536,622 and 551,926 are referred to.
