Title: Shaft positioning mechanism
Inventor: COLBY ROBERT A
IPC: G05D3/12
Filed: 1956-05-30
Abstract: 793,147. Stopping rotary elements in predetermined positions. COLLINS RADIO CO. May 30, 1956, No. 16770/56. Classes 80 (2) and 80 (4). [Also in Group XXXVIII] In an apparatus for positioning a variable condenser 12 in any one of a plurality of predetermined settings, a shaft 13, driving the condenser, is coupled through a clutch gear 15 and gear 16 to a motor 14, the clutch being arranged to slip when the shaft is held and rotate the shaft when it is free. The motor is controlled by a switch 18 operated by a lever 21 which through a roller 22 co-operates with a plate 40 of magnetic material, which is slidably mounted on shaft 13. The plate 40 also carries a plunger 45 which through an opening 39 in the frame 24 cooperates with spring-loaded balls 36 mounted around the periphery of a stop-wheel 34 fixed to the shaft 13. An electromagnet 31 is carried within a portion 28 of the frame, and guide-pins 43 on the portion 28 co-operate with corresponding openings in the plate 40 to prevent rotation of the plate. A spring 49 forces the plate 40 to the right. In operation the control knob 61 moves wiper contact 58 to the selected contact 57A ... 57L, and over the appropriate wire 56A ... 56L and switch rotor 53, which is attached to shaft 13, the magnet 31 is energized. The plate 40 is moved to the left causing plunger 45 to force ball 36 out of the opening 39 and simultaneously the switch 18 is actuated to start the motor 14. The motor runs until notch 54 on switch rotor 53 reaches a position corresponding to the setting of control 58 and the electromagnet is de-energized to allow the plate 40 to move to the right. Thus the switch 18 is operated to disconnect the motor, and the plunger 45 is moved to allow the ball 36 adjacent the opening 39 to seat therein and lock the stopwheel and thereby the shaft 13. Any rotation of the motor after disconnection is dissipated in clutch 15. Specifications 660,939, [Group XXXVIII], and 784,971 are referred to.
Patent GB-407924-A (GB)
Title: Improvements in and connected with electrical heating systems for buildings
IPC: F24D13/02
Filed: 1932-06-15
Abstract: 407,924. Electric radiators. TAYLOR, J. H., TAYLOR, G. P., TAYLOR, A., and TAYLOR, K. M., 14, Queen's Road, Huddersfield. June 15, 1932, No. 16887. [Class 39 (iii).] Buildings, vehicles, ships, or other structures are electrically heated by cables of a cross-sectional area of .001 square inch which, if embedded in the structure, may have a maximum loading of 1¢ watts per foot run, and if otherwise mounted may have a loading of 3 watts per foot. The maximum loading for cables of larger sizes will be directly proportional to their surface areas. In the case of cables insulated by vulcanised indiarubber the temperature of the metallic conductor should not exceed 100‹ F. ; paper or fibre insulation enables 130‹ F. to be reached. The cables may have protective sheathing. The heating effect of a circuit may be varied by altering the length and specific resistance of the conductors. Examples are given of the calculation involved in providing circuits for heating the various rooms and passages of a house. The heating effect may be varied by supplying the system from a transformer with several tappings or by the use of series parallel switches. The cables may be mounted in clips 16 and 17 on plates 13 provided with flanges 14 and covered by a plate 11 having clips 12 engaging with the flanges 14. Alternatively blocks 21 and 22 may be attached to the walls or ceiling of a room and covered by a plate 26, washers 23 on blocks 22 holding the cables in place. This construction may be varied by forming the blocks on a moulded plate attached to the ceiling or walls. If the cables are of tape formation, they may be secured to the required surface by adhesive and covered by an embossed plate or simply by wall paper. Reference has been directed by the Comptroller to Specification 272,166, [Class 39 (iii)].

Title: Improvements in or relating to electro-magnetically operated signalling devices
IPC: B60Q1/34
Filed: 1949-06-29
Abstract: 675,975. Road-traffic signals on vehicles; electric indicators. KRUMM, J. L. June 29, 1949. [June 30, 1948] No. 17239/49. Classes 40 (i) and 118 (ii). [Also in Group XXXV] A signalling device suitable for use in motor vehicles of the type in which a signalling arm is longitudinally projected from a casing upon energization of a solenoid associated with a ferromagnetic core forming part of the signal arm is characterised in that the said core is substantially longer than the solenoid and has an iron cross-sectional area varying in longitudinal direction. A. non-magnetic casing 10 containing a solenoid coil 1. and a slidable hollow iron core 2 having a portion 15 provided with triangular slots is mounted inside the wall 13 of a vehicle body adjacent an opening 14 through which the core may project. Fig. 3 is a developed view of the core 2 showing the slotted portion 15 and an unslotted portion 16. A small electric lamp 4 is fitted at the slotted end of the core in a translucent housing 5 itself secured to the core. The entire lamp and core system has a thin translucent plastic cover (not shown) which with the core is movable in the casing 10. The current is fed to the lamp 4 by means of a wire 6 and spring 7, which is secured to the core at 8 and serves to return the core to the inoperative position (as shown) when the solenoid is de-energized. To reduce friction two sets of three balls are provided, one set 11 moving with the core and the other set 12 being embedded in the wall of the casing. The return line of the lamp 4 is not shown but may be housed in the space between core and casing by winding helically round the core system. To obviate false operation by centrifugal force when rounding an opposite bend the opening 14 may be obturated by locking means (not described) which are automatically removed when the solenoid is energized. Instead of using triangular slots the varying iron crosssectional area may alternatively be obtained by providing the core with a conical bore or constructing it as a spiral spring having a linearly variable pitch. Both the triangular slot and spiral spring constructions allow the lamp to illuminate the entire length of the signalling arm, and the latter construction has the added advantage of flexibility and less liability to damage when extended.
