Title: Improvements in or relating to load-suspension trollies
IPC: B66C7/00
Filed: 1934-09-04
Abstract: 441,942. Suspended rail vehicles. FELCO HOISTS, Ltd., and TICHELLY, L. J., 17, Victoria Street, Westminster, and PALLETT, W. G., Victoria Works, Millhouses, Sheffield. Sept. 4, 1934, No. 25501. [Class 103 (iv)] In a load-suspension trolley of the kind in which one or more wheels travel along a single or dual track provided by an overhead rail, the trolley is maintained in a position of equilibrium and the wheels prevented from leaving the track, whether the trolley is loaded or unloaded, by means of one or more steadying rollers which are adapted to engage an under surface of the rail section so as to exert an upward thrust on the rail. In the construction shown, the trolley comprises a pair of parallel plates 14, 14a between which are arranged two pairs of wheels 10, 11 mounted on stub axles 12 and running on a dual track furnished by an I- section rail 13. The plate 14<a> at one side supports a driving wheel 21, while the plate 14 at the other side carries upon a pin 22 a steadying roller 23 which may be adjusted in a vertical slot 24 in the plate 14 and engages the under surface of the lower flange of the rail 13. In a modification, the adjustable roller is adapted to engage the under surface of the upper flange of the rail. In another construction one or more rollers, adjustable or not, may be mounted rotatably or integrally on a pin extending between the side plates 14, 14<a> and adapted to engage the under surface of the lower flange of the rail at fixed or variable selected points.

Title: Improvements in photographic camera shutters
IPC: G03B9/58
Filed: 1923-10-13
Abstract: 205,506. Bruns, H., and Gesell, H. Oct. 13, 1923. Shutters. - A system of planetary gearing is used for controlling the time of exposure. The shutter is set by depressing a lever 2, Fig. 1, thereby winding a spring motor member 1 which, on releasing the lever 2, actuates the shutter through a connecting rod. At the moment the shutter blades are open the nose 7 of a retarding lever 8, Figs. 1 and 3, contacts with a shoulder 6 of a recess 5 in the member 1 and delays the closing of the shutter until it is pushed out of the recess, the period of delay being controlled by the setting of the planetary gearing at the other end of the lever 8. The lever 8 is swung round its pivot 9 by a spring 10 and has at its other end gear teeth 11 engaging like teeth on a lever 12 swinging on a pivot 13. The other end of the lever 12 carries a rotatable pin 14 to which, on opposite sides of the lever 12, two gear wheels 15, 16 are rigidly attached. A gear wheel 17 which meshes with the wheel 15 is fastened to an escape wheel 18 both turning on the pivot 13. The anchor 19 of the escape wheel 18 is pivotally carried by a lever 21 which is held by a spring 23 against a pin of the shutter-blade actuating ring 22, so that the anchor 19 is only in engagement with the escape wheel 18 when the shutter is open, and during setting the mechanism can be returned to the starting position without resistance. The gear wheel 16 meshes with an internally geared wheel 24, Fig. 2, rotatably mounted coaxially with the lever 12 and having its teeth extending only part way round, the end of the recess limiting the movement of the gear wheel 16. On the outside of the wheel 24 a recess is formed extending about half-way round and receiving a pin 26 fastened to the shutter cover-plate 4. A rotatable indicating and regulating disc 27 is held by a screw 31 coaxially with the wheel 24, and carries two pins 28, 29 which are located in the path of a pin 30 fastened to the wheel 24. In the drawings the disc is shown set for the longest possible exposure, partly run off, the shoulder 25 on the outer recess on the wheel 24 resting against the pin 26, and the pin 28 bearing against the pin 30, movement of the internally geared wheel 24 being thus prevented. The gear 16 has then to roll off on the internal gear until the nose 7 of the lever 8 has been forced out of the way. By counter-clockwise rotation of the regulating disc 27 settings are obtained in which the rotation of the wheel 24 is successively increased and the rolling off of the gear wheel 16 on the internal gear, and consequently the movement of the escape wheel 18 is successively diminished, and the time of exposure lessened, until finally a setting is obtained in which the nose 7 of the lever 8 does not enter the recess 5 in the member 1 and the influence of the retarding device is completely eliminated.

Abstract: 1,174,205. Torque wrench. E. DAVIES. 29 May, 1968, No. 25608/68. Heading B3N. A torque wrench comprises a handle 1 in which a battery 14 is located, a pointer 5 connected to a socket 13, a scale member 7 which supports an adjustable stop 9, and a warning device 12 which may be a lamp, a buzzer, or both. In operation, the stop is set to the required position on the scale 7, and when the equivalent torque is reached the handle bends, pointer 5 engages the stop, thus completing the circuit from the battery to the warning device. In a modification, the battery 14 is omitted, and leads are provided for connections to a car battery.

Abstract: 1325824 Welding by fusion STEIGERWALD STRAHLTECHNIK GmbH 19 April 1971 [28 March 1970] 25697/71 Heading B3R [Also in Divisions G3 and H1] A workpice 9, Fig. 2, on which a weld is to be made by the electron beam from a generator 7, see Division H1, mounted on a carriage 19 within an evacuable chamber 9. The carriage 19 is supported for vertical adjustment on a device 22 and is co-ordinately movable in the horizontal plane by carriages 20, 21. on cooperating rails 24, 27. The carriage 19 is positioned by electric motors, not shown, responsive to control signals from a programmed electronic computer see Division G3. Errors in the instantaneous position of the carriage, due to the inertia of the positioning mechanism, are sensed by a photo-electric device which is interrogated by the computer to provide energizing signals to an electron-beam deflecting coil 6 whereby the errors are compensated. It is stated that abrupt directional changes in a butt weld, such as at the circled areas along a path 55, Fig. 5, between plates 54, 56 can be compensated by programming the computer to apply deflecting signals to the coil 6.

In a modification, the inner edges of the vanes form an obtuse angle, which may be rounded off. Reference has been directed by the Comptroller to Specifications 244,534 and 286,537, [both in Class 75 (iv), Lamps &c., Kinds &c. of].

Title: Improvements in or relating to thermionic cathodes

Filed: 1957-08-20
Abstract: 860,388. Cathode materials and processing. RAULAND CORPORATION. Aug. 20, 1957 [Aug. 20, 1956], No. 26265/57. Drawings to Specification. Class 39(1). In manufacturing a thermionic cathode coating, alkaline earth metal carbonate is first reduced by heat to form the emissive layer, and then, while maintaining the cathode at approximately operating temperature, particles of metal having a melting point higher than said temperature are evaporated on to it to form a pervious layer. The cathode is then maintained at operating temperature to sinter and stabilize the structure. The metal particles may be nickel, tungsten, tantalum, or stainless steel, and are evaporated from a sleeve containing a heater, after the manner of an indirectly heated cathode. Alternatively this sleeve may be given a positive potential with respect to the cathode, and the particles evaporated by electron bombardment. After deposition, further heating serves to sinter the particle structure and permeate it through with emissive material. Suitable pressures and voltages for an actual working example are given. The chemical and physical stability of such cathodes enables them to be stored after processing, or salvaged from unsatisfactory tubes.
