Abstract: 720,859. Spray-producers &c. LECHLER, P., and LECHLER, K., [trading as LECHLER, P., [Firm of]]. March 30, 1953 [March 31, 1952], No. 8787/53. Class 69 (3). A nozzle secured on or within a jet pipe is reversible so that in one direction of liquid flow therethrough a solid jet is produced, whilst upon reversal a sprayed jet is formed. In Fig. 1 the nozzle 2 on a jet pipe 1 has dispersers 5 which break up the jet to form a spray, and on reversal of the nozzle, Fig. 2, a solid jet issues. In Fig. 3 the nozzle 10 is rotatably mounted in a jet pipe 12, and liquid is fed to one or more pipes 8, 9 via a valve 6. In the position shown one or more spray jets are produced by the dispersers 5, 13 depending on the position of the valve 6, and on reversing the nozzle about its axis solid jets are formed.

Filed: 1941-07-17
Abstract: 548,772. Control of D.C. motors. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. July 17, 1941, No. 9039. Convention date, July 20, 1940. [Class 38 (iii)] A lift motor 13 is supplied from a Ward- Leonard generator 16 excited from a regulator machine R which has four fields, viz., a pattern field RPF excited under control of a car switch or of levelling switches; a differential field RDF across the generator armature to cause the generator voltage to equal that desired by the field RPF; an additive field RSF in the generator-motor loop to compensate for resistance drop with load, and a self-excited field RCF to maintain the regulator voltage at the value given by the other fields. During floor to floor runs the field RSF is partly diverted by closure of switch Kl, but during levelling this switch is open so causing greater than normal acceleration. During deceleration from high speed a resistance r4 in series with the pattern field RDF is shorted by switches Tl. Ql until a certain low speed is attained, thus giving a greater rate of deceleration. A brake is released by energization of coil 18a whenever the generator is energized. Specications 497,246 and 526,974 are referred to.

[Class 40 (iv).] A gramophone pick-up comprises a casing 11 containing a pair of horseshoe magnets 23 enclosing a coil 17 and having their adjacent poles of opposite polarity and an armature 27 formed with trunnions 28 surrounded by rubber tubing 29 and journalled in bearing members 30 clamped between the magnets and the lower part of the casing. Each of the bearing members, which are preferably formed of magnetic material, is substantially U-shaped in plan and the limbs 31 of each are bowed to form corrugations 32 whilst the lower part of the casing is cut away at 33 to accommodate the trunnions and the corrugated part of the lower bearing member. The upper end of the armature, which is formed as a fin 26, is located between the ends of a length or two separate pieces of rubber 25 positioned in grooves 24 in the upper pole faces. When it is desired to provide adjustable damping means, the fin 26 is made longer, the strip 25 is kept clear of the magnets and adjusting screws are provided in diagonal bores in shoulders 43 on the casing. The casing 11, which is formed with a rearwardly extending lug 12 for attachment to a supporting arm, is closed at the front by a cover 14 and is provided with a hole 19 in its rear wall through which the moulding 18 containing the winding 17 is inserted, a flange 20 on the moulding being screwed to the rear wall to hold the winding in position. The outer part 21 of the moulding 18 contains terminals for the winding and is surrounded by a flange 22 which is carried upwardly to strengthen the lug 12. The magnets are clamped against the. rear wall of the casing by screws 35 and washers 36. Fig. 3 shows a modification in which only one bearing member 37 is employed, the trunnions 28 being supported from beneath by a detachable part 38 of the lower wall of the casing. In this construction, the casing 11 is formed with positioning means for the magnets 23 in the form of a short projection 40 from the rear wall thereof, two downwardly extending bosses 41 and a ridge 42 projecting for a short distance only from the rear wall, the magnets and bearing member being clamped between the bosses 41 and the detachable part 38. Instead of providing rubber tubing 29 for the trunnions, the bearing member or members and the groove of the detachable part 38 may be lined with resilient material.
