Abstract: 766,533. Electric air heaters. GILLOTT ELECTRO APPLIANCES, Ltd., [formerly GILLOTT ELECTRO STEAM COOKERS, Ltd.]. April 7, 1953 [April 4, 1952], No. 8604/52. Class 39(3) An air' heater comprises an electric heating element disposed within' an open ended tubular member which is located within and spaced from the wall of an outer casing having openings at each end for the admission and escape of air, the tubular member forming a flue for air to pass through the heater and thence be ceflected through the escape opening by a deflector mounted within the casing above the tubular member. As shown the heater comprises a cylindrical outer casing 10 with a perforated base plate 13 'and upper and lower air outlet and inlet grids 24, 25, and a rectangular cross-section inner tube 16, the lower insulating end 18 of which carries electric heating elements 15 in the form of resistance coils wound on rods or tubes of refractory material. The lower end of the part 18 is perforated at 20 and encloses a thermostat 31 and supports an indicating lamp 32. At the top of the casing 10 a deflector 23 is arranged beneath a cap 22 carrying a handle 35. Air passing up the tube 16 is heated, while cool air passes up the space 21 formed between the tube 16 and the casing 10. In a modification, the tube 16 comprises a single refractory cylindrical tube with support legs at its lower end. Feet 12 on the base plate 13 ensure that if the heater is knocked over, the plate 13 is higher than the openings 24 whereby air flow through the heater is reversed and the thermostat 31, which is normally responsive to incoming cool air, becomes influenced by hot air passing through the heater and therefore operates to de-energize the heating elements.

Title: Improvements in and relating to dynamo electric machines
Inventor: RABY KENNETH FRANCIS
IPC: G05B11/01
Filed: 1952-04-09
Abstract: 721,698. Exciting dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. April 9, 1953 [April 9, 1952], No. 9083/52. Class 35. In order to prevent the output current of an amplidyne from exceeding a definite adjustable maximum value substantially independent of the load, the compensating winding of the amplidyne is connected in series with the load arid also in parallel with a circuit comprising a source of constant P.D. and a unidirectional current-conducting device connected in series and poled in opposition thereto. Fig. 1 shows an arrangement to limit the magnitude of the current I flowing in the direction shown. Here the brush 5 is connected to the negative pole 11 of a constant P.D. source, of which the positive pole 10 is connected through a half-wave rectifier 9 to an output terminal 7. If the control field winding 8 is excited in such a way that a current I flows in the load as shown, a P.D. will be set up between the ends 7, 5 of the compensating winding 6, the potential of 7 being higher than that of 5. As long as the magnitude of the current I is such that the potential of 7 above 5 is less than that of 10 above 11, the point 10 will be positive with respect to 7, but no current would flow from 10 to 7 owing to the rectifier 9. If the load current is increased to such an extent that the P.D. 7-5 exceeds the P.D. 10-11, the potential of 7 will be higher than that of 10 and consequently current will flow from 7 to 10 via the rectifier 9 and the current in the winding 6 will be less than the load current in the armature 1 between the brushes 4-5 by the amount of current in the circuit 7-9-10-11-5. Thus when the balance of armature reaction m.m.f. and compensating m.m.f. is upset, the amplidyne output e.m.f. will cease to be determined mainly by the winding 8 and will rapidly be reduced due to the undercompensated armature reaction of excess load current. Thus the load current will be limited automatically at a value only slightly exceeding that which makes the P.D. 7-5 equal to P.D. 10-11. Hence the load current may be limited by adjustment of the P.D. of 10-11. Reversal of polarity of 10-11 and of rectifier will provide current limit in the opposite direction. When it is desired to limit the current in either direction the arrangements shown in Figs. 2, 3, 4 may be used. Where the load current may flow in either direction the rectifier 9 is replaced by a bridge rectifier as in Fig. 2 (not shown), or by using two separate independently adjustable potentials 10-11 and 11-12 as in Fig. 3, or as illustrated in Fig. 4 (not shown). Specification 606,652 is referred to.

Title: Electromagnetic relays for alternating voltages and sensitive to certain harmonics
IPC: H01H51/30
Filed: 1955-03-30
Abstract: 775,924. Electromagnetic relays; electromagnetic interrupters. SOC. INDUSTRIELLE DE TELECOMMANDE ET DE TELEMECANIQUE. March 30, 1955 [April- 6, 1954], No. 9281/55. Class 38(5) A relay sensitive either to a superposed voltage comprising an even harmonic shifted in phase relatively to the fundamental component or to a superposed voltage having a frequency close to an even harmonic, has its magnetic circuit saturated. The relay comprises a core 1 energized by a coil 5 connected in series with a condenser 6 to the A.C. supply. A permnaent magnet armature 4 pivoted in an opening 3 in the core carries a contact 14 co-operating with a pair of contact springs 16a, 16b. Considering firstly the case where the harmomic is shifted out of phase, this shift may be #/2 or 3#/2 and the fundamental frequency may be 50 c.p.s. and the harmonic 200 c.p.s. The magnetic circuit may be either just saturated-in which instance the armature takes up the central position shown when the harmonic is absent; or the magnetic circuit may be saturated beyond the knee portion of the magnetization characteristic-whereby there is no magnetic bias on the armature in the absence of the harmonic. In this instance the armature either remains in a position displaced from its central position to which it is moved by the harmonic until it is moved into its opposite displaced position by a harmonic 180 degrees out of phase with the first applied harmonic; or, the armature may have a biasing spring to return it to one of the displaced positions. Considering secondly the case when the harmonic has a frequency close to an even harmonic, e.g. 199 c.p.s., the phase shift is continually varying and returns to the same value each second. Thus the armature 4 is oscillated once per second providing the armature assembly is constructed to have a similar natural frequency. of vibration. In a modification of this embodiment the armature may be coupled to a mechanical system (not shown), to drive a contact or contact operating member step-by-step. Preferably, the characteristics of the relay are such that the circuit of coil 5 is resonant at the harmonic frequency. A bar 7 shunting the core 1 is adjustably mounted on lugs 8a for varying the air gaps 10. Undesired vibration of the armature may be prevented by an inertia disc mounted on the armature spindle (Fig. 4, not shown). The theory underlying the relay operation is explained with reference to graphs of the fundamental and superposed voltages (Figs. 5, 6, not shown) .
