[Also in Division HI]  A method of coating a wire wound electrical resistor 10 in fused vitreous enamel 12 comprises the steps of preheating resistor 10 with a flame 28‹ to #400‹ C., adding enamel frit 34 (m. pt. #450‹ C.) to the flame so that it melts before reaching and coating the resistor, and then cooling the resistor to #300‹ C. in a blast of cold air, the whole process taking not longer than about 5 seconds. The resistor may be mounted in rotating chucks 24, 26 by its 16-18 AWG copper terminals, thus improving heat dissipation. A mild steel shield 40 with a heat resistant silicone rubber pad 38, or shields (68, 70, Fig. 2, not shown) may cover part of the resistor. The resistor is preheated and cooled in periods of about one second, and the enamel frit of 150 mesh is applied for about 2 seconds to produce a layer about 1/16 inch thick. The burner 30 may be moved during the application of the layer, and a plurality of burners may be used. The gas used is CH 4 , H 2 , CO or household gas.

Title: Improvements in power assisted steering gears for vehicles
IPC: B62D5/06
Filed: 1955-05-10
Abstract: 800,813. Vehicle power steering. MULLER, F. and MULLER, M., [trading as FULMINAWERK KOMM-GES., F. MULLER]. May 10, 1955 [May 14, 1954], No. 13475/55. Class 79(5) In a power assisted steering gear, as shown in Figs. 1 to 3, parts 1, 4 of the steering column are interconnected by a differential gear 3 comprising two spurwheels 19, 20 and a planet gear 21 and the planet gear carrier 22 has an arm 25 whereby differences of rotation between the parts 1, 4 control a spring-held slide valve 10 which springs urge the carrier 22 into a neutral position. As shown in Fig. 1 the invention is applied to a vehicle steering gear 5 having a drop arm 6. A double-acting piston in a cylinder 9 is connected by a rod 7 to the arm 6, the cylinder 9 having supply conduits 11, 12 connected by the valve 10 and by a conduit 17 to a reservoir 16 and by a conduit 13 to pump 14. The planet gear carrier 22 can be locked by a screw 24, is journalled on the portion 4and the arm 25 is connected by pins 26 to a groove 27 in a valve spindle 28. Within the valve casing 29 the spindle 28 carries lands 30, 31 and is centred by springs 32, 33 which also serve to centre the carrier 22. Between the casing and the spindle is a sleeve 40 having ports 34...39, the ports 34, 35 connecting with the cylinder supply conduits 11, 12 and the ports 36, 37 normally communicating through the porfs 38, 39 with the conduit 17. With the spindle 28 in its centre position pressurized oil from the conduit 13 passes to the conduits 11, 12, 17. Movement of the spindle to right or left consequent upon manual rotation of the wheel 2 and hence differential movement in the gear 3 causes increased flow to one side of the piston 8 and throt-. tling of the flow to the other side, which gradually is fully connected to the exhaust conduit 17, consequent movement of the piston 8 giving power assistance to the steering gear. In a modification, Fig. 4, the valve spindle 28 is formed with reduced portions 41, 42 each closed on one side by a collar 30<SP>1</SP> against which bears a land 30 under the action of the spring 32, and the exhaust conduit is formed by end branches 17,<SP>1</SP> 17<SP>11</SP>. Ports 34<SP>1</SP>, 35<SP>1</SP> associated with the conduits 11, 12 are formed as slits distributed on the circumference with the edges of the slits being axially offset so that a gradual opening of the port is obtained. Alternatively the edges of the slit may be of semicircular shape.

Classes 40 (6) and 40 (7). In a cathode-ray tube deflection circuit (e.g. the frame deflection circuit of a television receiver) the deflection coil 11, which is energized from the scanning generator output valve 1 through a transformer 8, is connected in series in the main D.C. supply lead 16 of the equipment for the purpose of receiving a current for centring the deflection. As illustrated the coil is in the negative supply lead between a filter inductance 12 and a resistor 7. As an alternative, the coil may be connected in the positive lead, or may have parts in both leads. The voltage set up across resistor 7 is applied through C.R. network 5, 4, to the cathode of valve 1 to correct for non-linearity introduced in the scan by any mains hum in the supply current. Part of the supply current flows through the secondary winding 10 of transformer 8 and is arranged to compensate for the magnetic induction due to the anode current of valve 1 in the primary winding 9. By this means magnetic saturation is avoided and the transformer may be constructed of normal magnetic materials without an air gap.
