Title: Improvements in or relating to thermionic oscillation generators
IPC: H03B5/30
Filed: 1934-06-04
Abstract: 418,429. Valve generating circuits. ETABLISSEMENTS E. BELIN, 56, Faubourg St. Honore, Paris. June 4, 1934, No. 16623. Convention date, June 2, 1933. [Class 40 (v).] The frequency of a forkcontrolled valve generator is maintained constant during temperature variations by the use, in the cores of the fork-maintaining coils or of other coils associated with the valve circuit, of magnetic material whose permeability varies with temperature. As shown in Fig. 1, the plate coils b and the grid coils c of the valve enclose cores h, i which are associated with the tines of the fork a. Steady flux is maintained in the cores by permanent magnets d, e or by other coils traversed by direct current. The magnetic circuit also includes a branch f, g or f<1>, g<1> formed of material whose permeability decreases with a rise of temperature. If the frequency of the fork tends to rise with temperature, the branch circuit f, g is, as shown, arranged as a shunt to the main magnetic circuit, whilst if the fork frequency falls with rising temperature, the auxiliary core member is placed in series in the magnetic circuit. The auxiliary core member is in two parts of which one is adjustable to vary the gap between them. In a modification shown in Fig. 3, the compensating coil L, with a core whose permeability varies with temperature, is connected in series with a condenser C and with the reaction coil b which maintains the fork a in vibration. If the fork has a positive temperature coefficient, the reaction circuit is arranged to be resonant at the maximum of the temperature range. The coil L may be shunted by a condenser, and the combined impedance arranged to be a maximum when the temperature is at its lower limit (Fig. 4, not shown). When the fork has a negative temperature coefficient, the opposite limits of temperature are taken. The variable coil L may be arranged as a shunt to the fork-maintaining coil b (Fig. 5, not shown) ; or it may be connected in series between the plate and the positive of the H.T. supply (Fig. 6, not shown).

Filed: 1953-06-16
Abstract: 749,522. Controllers. SUTCLIFFE, Ltd., R., HILL, D. S., JOHNSON, I., and METCALFE, P. N. March 30, 1955 [June 16, 1953], No 16642/53. Class 38(3) A control switch 13 for an electric motor 1 is resiliently biased to an open position and is closed when an operating lever 2 is actuated to release a brake for the motor. The actuating means for the control switch comprise an adjustable link 6 pivoted on the member 2 and coupled to lever 8 which is secured to spindle 9 in a cable-operating device 10. Longitudinal movement of the cable 11 resulting from upward movement of the brake lever 2 causes the switch 13 to close. The control switch is connected in parallel with another switch which is closed when the motor is initially switched on and is opened at a predetermined period after the motor has been energized. Thus, if the brake is not released within the predetermined period, then the motor is disconnected. Correct operation of the brake and the associated mechanical linkage, however, allows the switch 13 to maintain the motor circuit when the time-controlled contacts of the other switch are opened.

Abstract: 703,662. Heating fluids by electricity. HEAT-X-CHANGER CO., Inc. July 13, 1951 [July 20, 1950], No. 16647/51. Class 39 (3) An electric fluid, e.g. water, heater comprises a helical water tube 26, 30, Fig. 3, and a concentric helical electric heating element 20, a cast metal block 18 surrounding the tubes 26, 30 and element 20 to provide good heat transfer therebetween and to act as a heat reservoir, a control element 36, selectively responsive to the temperature of the block 18 and incoming water, being mounted on the surface of the block 18. The water heater 12, Fig. 2, comprises the aluminium block 18 cast about copper water tubes 22 and two coiled electric heating elements 20, the block 18 being supported in a metal casing 14 by means of insulating annular rings 15, 23 and a metal cylinder 13, a stud 17 positioning the block 18 in the casing 14. The space between the block 18 and casing 14 is filled with fibre glass. Water enters at 28 and flows through an inner copper coil 26, Fig. 3, and then by an outer concentric coil 30 to the exit 32. The elements 20 are arranged between the coils 26 and 30 with their turns interspaced to form a double helix. The bulb 36 of a thermostat is adjustably placed in a well 38 adjacent the inlet 28 and acts to close the heater circuit at a low temperature and open it at a high one. Thus when no water is flowing, the block, with any water therein, is maintained at a high temperature. The heater 12 is described in conjunction with a coin-actuated device for supplying hot beverages.

Title: Machines supported by rotary propellers, with combined propelling, flapping and steering action
IPC: B64C33/00
Filed: 1931-06-08
Abstract: 383,973. Ornithopters. KRAUSS, A., 68, Torbay Road, Brondesbury, London. June 8, 1931, No. 16686. [Class 4.] An ornithopter comprises wings hingedly mounted on cranks fixed to transverse driving shafts, the hinges being rotatively mounted in the cranks to permit of controlling the angular position of the wing during its rotation, and the beating movements of the wing being effected by linking each wing to a second, parallel, crank arm of greater throw than the first, to which it is connected by gearing so as to rotate in phase therewith. Wings A are connected by flexible hinges G to the shaft of a chain wheel L which shaft passes freely through a crank arm D. Crank arm D is formed as a circular disc and carries bearings for a similar disc to which the hinge C is connected. Shaft E of crank arms D is driven by chain gearing from a symmetrically disposed lower shaft F formed with cranks H. Freely mounted on shaft E are chain wheels M connected to chain wheels L. Levers N secured to hubs P of chain wheels M permit of adjustment of the angle of incidence of the wings during their rotation. Links I connect the crank arms H with the wings A and are so arranged that when crank arms D, H are both horizontal the longitudinal axes of the wings are also horizontal. Crank arm H is longer than crank arm D so that the wing is caused to flap about its hinge C during rotation, as shown in Fig. 5. The levers N may be operated by hand independently for steering, or may be operated automatically by connection to eccentrics O on shaft F, in which case means are provided for disconnecting them when required. Lever N is reciprocated by eccentric O by means comprising an intermediate rocking lever N<1>, Fig. 12, and an arcuate rack 1 meshing with a spur-wheel 3 carried by lever N. Spur-wheel 3 is held against rotation by a ratchet wheel 4, Fig. 13, fixed to its shaft and by a pawl 6 pivoted to a handle 5 on lever N. Disconnecting pawl 6 permits lever N to be moved by hand, the rack 1 merely rotating spur-wheel 3 idly. The rotation of the wings may be reversed for landing. The wings may be folded for storage by turning the chain wheel L until the wings are vertical and then turning the wings back against the body. More than one pair of wings may be fitted to a machine. The wing framework is flexible and is constructed as follows : the fabric is spread out flat and steel ribbons Y are passed through pockets extending transversely across the fabric. Longitudinal strips L are fixed at intervals to ribbons Y forming a network. A shaped steel plate V is fixed intermediate of the ends of the fabric at right-angles to ribbons Y. Longitudinal and lateral tension bands T are fixed to the shorter lengths of the ribbons, the other portion of the fabric is then folded about the part V and connected up as shown in Fig. 11.
