Title: Improvements in or relating to an Out-of-Balance Vibrator for Road-Tamping.
IPC: E01C19/34
Filed: 1969-01-13
Abstract: 1,196,894. Vibrators. WACKER-WERKE K.G. 13 Jam, 1969 [15 Jan., 1968], No. 1872/69. Heading F2X. A vibrator for use in a road tamping machine has a first unbalanced mass 2 fast on a shaft 1 driven by sprockets 3, 5 and chain 4 by a control shaft 6, in turn driven by bevel gears 7, 8. A second unbalanced mass 9 is freely rotatable about the shaft 1 and is driven through gears 12, 13, respectively fixed to mass 9 and freely rotatable on shaft 6, and a coupling formed by engageable lugs (15), (16) on the gear 13 and a sleeve 19 splined to the shaft 6. Axial movement of the sleeve 19 by a pin 18 against a spring 17 allows relative movement between sleeve 19 and gear 13 and thus between masses 2 and 9 to change the direction of vibration. Lugs (15), (16) again drivingly engage in a position 180 degrees out of phase with the first position when radial pins (21) on the sleeve 19 ride up cam surfaces 20 on the gear 13.

Abstract: 535,153. Filters. CHEMA MANUFACTURING CO.. Ltd., and SIGMUND, M. Jan. 31, 1940, No. 1924. [Class 8 (ii)] A filter element is formed by winding spirally strips 1, 2, of filter paper or fabric with narrow spacing strips 3, 4, 5, 6, arranged as shown in Fig. 1, the strips 4, 5, being of relatively thick, stiff and impervious material such as cardboard and the strips 3, 6 being of corrugated material such as paper. Adhesive is applied to the faces of the strips 4, 5, and, if necessary, to the ridges of the strips 3, 6. The element is completed by an impervious disc 7, Fig. 3, closing the central space at one end, and an impervious flange 8 encircling the periphery at the other end and fitting in a container in which the element is used. Fluid supplied to the upper end of the container flows past corrugated spacers 3 into alternate spaces, filters through the strips 1, 2 into the adjacent spaces, passes the spaces 6 to the lower portion and then filters again to the spaces below the spacer 4 and leaves at the lower end. The strips 5 may be inset from the edges of the filter strips to form channels to receive layers of bitumen and latex, which serve as a seal. The elements are stated to be applicable in respirators for personal use and in the air treatment plant of gas shelters.

Title: Improvement in driving motors for gyroscopes
IPC: G01C19/38
Filed: 1945-01-24
Abstract: 591,598. Gyroscopic apparatus. AKTIEBOLAGET NORDISKA ARMATURFABRIKERNA. Jan. 24, 1945, No. 1924. Convention date, Jan. 8, 1944. [Class 97 (iii)] The rotor is provided with a short circuited winding and is driven, during normal running, by single phase A.C. supplied to a stator carried by the inner gimbal 8 through point contacts 4, 6, and 5, 7 in line with the pivotal axis of the outer gimbal 3 and point contacts (not shown) in line with the pivotal axis of the inner gimbal 8. For starting up, the gyroscope is supplied with three-phase A.C., the third phase being fed through an auxiliary feeding circuit including a contact member (e.g. the spring 38 cooperating with the rod 39 depending from the gimbal 8) which is controlled by caging mechanism so that the auxiliary feeding circuit is opened when the gyro is uncaged. A switch 40 co-operates with a stop 43 on the caging mechanism to ensure that the circuits to the stator are opened or closed only when the gyro is caged. In the gyro vertical shown, operation of the plunger 22, acting through the bell crank lever 25, 26 27 raises a roller 30 into contact with a heart-shaped cam 31 fixed to the gimbal 3, causing the latter to turn to the horizontal position. The roller 30 then enters a recess in the cam 31 and engages one end of a lever 36 pivoted at 34 on the gimbal. A roller 35 at the other end of the lever 36 then engages a heart-shaped cam 33 on the gimbal 8 and restores the latter to central position, the roller 35 then entering a recess 33a. Further operation of the rod 22 causes a member 37 to raise the spring 38 into contact with the rod 39. In a modification the rod 39 may incorporate a switch by which the stator windings, which are connected in series or parallel for normal running, may be automatically changed to a star or delta connection when the spring 38 presses against the rod 39. The position of the gyro is indicated optically by means of light from sources 15, 16, on the outer gimbal 3, the light being directed on to cylindrical mirrors 17 or 18 fixed to the inner gimbal 8 and reflected, via further cylindrical mirrors 19, 20, fixed to the gimbal 3, to the window 2. The axes of all the cylindrical mirrors are parallel to the axis supporting the gimbal 8 in the gimbal 3. The Specification as open to public inspection under Sect. 91 describes a directional gyroscope in which single phase current is supplied through the gimbal axes to the vertical ring and then to a main stator winding on the inner gimbal and also through a capacity (and/or resistance) to an auxiliary winding. This matter is not included in the Specification as accepted.

Title: Improvements in load limiting clutch
IPC: F16D43/21
Filed: 1927-01-25
Abstract: 288,750. Dehn, r. B., (Healey-Aeromarine Bus Co., Inc.). Jan. 25, 1927. Clutches.-In load-limiting clutches, spring- pressed friction elements are driven by antifriction means acting to separate them with a force proportional to the driving torque in either direction of rotation. A driving-member 10, Fig. 1, contains in symmetrical cam-like depressions 21 balls 24, which engage also tapering depressions 22, 23 in loose discs 18, 19. These discs are drawn together by adjustable springs 20 and normally press into contact friction plates 15, 16 splined to the driven shaft 13 and slidable on pins 17 respectively. On predetermined overload, the balls 24 wedge the discs 18, 19 apart and allow slip. In order to minimize error due to variation in the coefficient of friction of the clutch plates, the bulk of the spring load is designed to be taken by the balls 24 when drive is being transmitted. In a preferred modification, the driving-member 10<a>, Fig. 3, has a central flange with conical pockets 21a on both sides to receive balls 24<a>, 24b which engage conical pockets 22<a>, 23a in the pressure-discs 18<a>, 19<a>. The clutch spring is formed by dished discs 20a, adjusted by screws 17a, which are locked in set position by engagement of the turned-up edge of one disc 20<a> with notches 27 in their heads.

Title: Stock ticker printer on central energy system
IPC: H04L12/10
Filed: 1930-01-22
Abstract: 347,133. Type - printing telegraphs. CREED & CO., Ltd. and SALMON, R. D., Telegraph Works, Croydon. Jan. 22, 1930, No. 2224. [Class 40 (iii).] In a signalling system operating on signals separated by intervals of direct current, an electromotor SM of a continuously rotatable type, connected to a line circuit L, is operated chiefly in the intervals of direct current, and winds up energystoring means for actuating apparatus under the control of the signals. A relay PR, responsive to current reversals to control an escapement of a rotatable type wheel, is connected in series with a capacity K in the line circuit, and the electromotor is connected in parallel to wind up a weight or spring motor. Two condensers A, B are alternately charged through rectifiers A1, A2 by the current reversals and are discharged through an electromagnet PM to operate a printing anvil or letter feed, when the direct current at the end of the signal operates a slow-acting relay NPR. Alternatively, the condensers are alternately charged through a contact tongue operated by the relay PR (Fig. 2, not shown). Specification 346,003 is referred to.

Title: Crimped electrical connections and methods and tools for making them
IPC: H01R4/20
Filed: 1950-01-30
Abstract: 673,198. Cable and wire terminals. AIRCRAFT-MARINE PRODUCTS, Inc. Jan. 30, 1950 [Feb. 1, 1949], No. 2360/50. Class 38 (i). [Also in Groups XXII and XXIII] To prevent damage, caused by interrupting the natural flow of the material, to the plastic sleeve 26 placed over the ferrule 25 of a connector 27, as described in Specification 613,013, the crimping dies 37, 38 have their surfaces 35, 36 smoothly curved and their lateral edges 39 abruptly rounded off so that an elliptical crimp is produced. The ratio of the radius of the die surfaces to the width thereof, i.e. from one die edge 42 to the other die edge 42, ranges from 1: 1.5 to 1: 1.8, and is preferably 1: 1.7. The major axis of the ellipse is from 1<SP>1</SP>/ 5  to 2 times the minor axis. The edges 42 are preferably chamfered but may be sharp if the die material is hard enough, and the edges 28 of the ferrule also should be abruptly chamfered where they contact the sleeve. The length of the dies should not be less than that of the ferrule and at least four times the thickness of the crimped sleeve. The width of the die surface 35 should not be much greater than the diameter of the sleeve and the die 38 should so fit between the walls 40 of the die 37 that a smooth curve is produced at the meeting points. Additionally, one wall 40 may be on one die and the other wall on the other die. In modifications, two cables may be crimped together in a sleeve having an insulating sleeve either face-to-face, or parallel or alongside. Hexagonal crimps can be used as in Specification 585,507 to secure the cable insulation and the sleeve, Figs. 7 to 10 (not shown). As a further precaution the die surfaces may be rubber-lined, Fig. 14 (not shown). The dies are intended for use with hand-operated crimping tools.

Title: Improvements in or relating to motion transmitting mechanism
IPC: G05G19/00
Filed: 1926-01-27
Abstract: 246,847. Bethlehem Steel Co., (Assignees of Nieman, H. W.). Jan. 28, 1925, [Convention date]. Reversing-gearing; clutches, friction.-Means for repeating in a power-driven element the rotation in either direction of a manually-controlled element comprises a driven shaft, a power shaft, two members driven thereby in opposite directions, a constant-pressure friction coupling between one member and the driven shaft, a variable-pressure friction clutch between the other member and the shaft, and a coaxial manually-driven element so connected to control means for the clutch as to disturb the normal equality of slip between the two members and the shaft to cause it to rotate in the same direction as the manually-driven element. A power shaft 10 drives oppositely, through pinions 12 .. 14 and worms 15', 16', worm-wheels 18, 19 loose on the driven shaft 17. The wheel 18, under adjustable axial spring pressure, and a disc 20 fast on the shaft 17, together with an interposed cork or other friction disc 21, constitute a slipping coupling, and the wheel 19 is connected to the shaft 17 by a compound band clutch normally exerting the same slip resistance as the coupling 18, 20, so that the shaft remains stationary. A primary contracting-band 32 surrounding the hub 25 of the wheel 19 is connected at one end to an arm 34 on a rotatable control element 35 and at the other end 28<1>, through a lever 28, to one end 40 of an expanding band 26 coacting with the interior of the wheel. The other end is secured to a pin 31, this pin and the pivot 29 of lever 28 being carried by a disc 30 fast on the shaft 17, through a slot in which disc passes the arm 34. On manually turning the spindle 35, either directly or by remote control, in a direct ion to tighten the band 32, the effort is multiplied in the band 26, and the shaft 17 rotated in the same direction as the spindle so long as its rotation is continued. On turning it to slacken the bands 32, 26, the coupling 18, 20 predominates, and the shaft 17 again follows the part 35. On ceasing to drive, equilibrium is automatically restored. The bands 32, 26 are faced with cork &c. 33, 27, and the band 32 is of lighter section than the band 26. The bands may further taper from end to end in width or thickness or both. The Specification as open to inspection under Sect. 91 (3) (a), comprises also the replacement of the constant-pressure friction coupling and its driving-member by any constant-torque means, such as a magnetic field, spring, weight, or normal torque-load on the driven shaft. This subject-matter does not appear in the Specification as accepted.

Filed: 1925-01-27
Abstract: 245,947. Imray, O. Y., (Bergman Elektricitõts-Werke Akt.-Ges.). Jan. 27, 1925. Driving printing-machines. - A main working motor A is assisted by an auxiliary motor B which also serves to feed the paper at low speeds, the two motors being always in driving connection with the machine shaft F. Both motors are controlled by variation of field current and armature current so that the auxiliary motor provides all the power at low speeds and takes up a diminishing proportion of the load with increasing speed. In the arrangement shown in the Figure, the starting switch H first makes connection to the armature of the motor B and accelerates it through the steps 1 - - 6 before putting in the armature of the motor A. The starting switch also in its initial position connects the motor B with a solenoid 0 which automatically regulates the current. A rheostat M controls the fields of both motors in common. Power-speed diagrams are given in the Specification.
