Patent GB-283603-A (GB)
Title: Improvements in and relating to motor mechanism actuated by springs and electromagnetic impulses
IPC: F16H31/00
Filed: 1926-07-14
Abstract: 283,603. Muck, O. July 14, 1926. Oscillating machines.- A device for converting electric vibrations into mechanical energy, e.g. for operating switches, comprises an alternating- current magnet adapted to vibrate a spring tuned to the frequency of the current and arranged to strike a separate and pivoted actuating member which, in its turn, acts on the member to be driven, so that the spring is damped by the impact but not materially by friction, and the distance between the spring and the separate actuating member is variable. In the construction shown in Fig. 1, the tuned spring a strikes a tapper e which is pivoted at g and carries a pawl b by which it turns a wheel c. The damping effect of the tapper upon the spring is controlled by a spring e<1> bearing on the tapper, the distance of the spring e<1> from the spring a being adjusted by a screw d. The leaf spring a may be replaced by a coiled or other spring a<1>, Fig. 4, and the tapper may be pivoted centrally as at g, Fig. 4, in which arrangement it may carry either a switch contact v, as shown, or a pawl for turning a wheel. In the arrangement shown in Fig. 4, the tapper alternately opens and closes the switches x and v, s in alternative circuits. A spring y is arranged to return the tapper slowly so that the switch v, s remains closed while the tuned spring a<1> is vibrating, and the switch x is closed when the vibration stops. In the arrangement shown in Fig. 5 the tuned spring a is vertical, while the tapper normally rests on a contact x to close one circuit, but when the spring a is vibrated the tapper engages a contact z<1> to close another circuit. In the arrangement shown in Fig. 7, the circuits I and II are selectively opened and closed by energizing the magnet coil m by currents of different frequencies corresponding to the tuning of two springs u, v, which are adapted to throw a tumbler H to one side or other of its pivot g and so close the corresponding switch t, x.

Title: Process and apparatus for detecting asymmetry in an electrolyte
Inventor: CHEMLA MARIUS
IPC: G01N27/416
Filed: 1962-05-09
Abstract: In the process described in Specification 921,366 according to which salt solutions are electrolysed to separate isotopes by adding to the bath a substance which dissolves metal tending to be deposited on the cathode and controlling the electrolysis by measuring periodically the voltage between the cathode and a reference electrode, the normal anode is used instead of a separate reference electrode which introduces disturbing effects. In operation, electrolysis current is interrupted and the potential difference between the cathode and anode is measured, and if different from a predetermined value thus revealing a concentration gradient in the vicinity of an electrode, the electrolysis current remains cut off until the normal value is established, whereupon electrolyte current is restored.  The process may be applied to all types of electrolyte.  The apparatus described is similar to that of Specification 921,366, but employs time-operated relays, switches and measuring instruments having electrical contacts with which a pointer may contact at predetermined positions, whereby the process is rendered automatic.

Abstract: 513,408. Drilling machines ; brakes. WESSELMANN-BOHRER CO., AKT.-GES. Oct. 19, 1938, No. 17865/39. Convention date, Jan. 27, 1938. Divided out of 512,294 under which a Specification was laid open to inspection under Sect. 91 of the Acts, April 24, 1939. [Class 83 (iii)] In the spindle or work feed of a drilling &c. machine, wherein the spindle &c. is fed by hand and automatically returned by a balancing means, a brake is provided for preventing the return movement when the hand feed lever is released temporarily. The quill 2 containing the drill spindle 3 is fed by a pinion 4 on a shaft 5 to which is attached a balancing and returning spring 7. The other end of the spring is attached to a casing 8 which is angularly adjustable to vary the spring tension. A clutch disc 23 fixed to the shaft 5 has teeth 10 engageable with teeth on a sleeve 12 slidable and rotatable on a boss 13 attached to the shaft and having one or more hand feed levers 15 pivoted thereto at 14 so that lateral movements of a lever 15 by the operator will engage the clutch and allow the lever to feed the spindle by rotation about the axis of the shaft 5. A roller 19, Fig. 2, is located in a recess 18 of the drill head 1 and is pressed by a spring 21 into engagement with the disc 23 and a wedge-shaped plate 22. If the operator desires to make successive strokes with the lever- 15 during one feed movement of the spindle, the roller 19 will become wedged against the disc 23 when the clutch 10 is disengaged and so prevent the spring 7 from returning the spindle, but at the end of a drilling operation the roller may be depressed by a cam 24 actuated by a hand lever 25 to allow reverse rotation of the shaft 5, whereupon the spring 7 may return the spindle without rotating the hand levers 15. The strength of the spring 21 and design of the plate 22 may be such that upward pressure on the hand levers 15 will overcome the resistance of the brake 19 and return the spindle.

Abstract: 444,146. Conveyers; hoppers. GIBBONS, J. S., Brick House, Dunmow, Essex. June 21, 1935, No. 17924. [Class 78 (i)] A device for feeding fruit &c. to a grading- machine comprises a continuously rotating recessed drum 12 which receives the fruit from a conveyer 6b and transfers it to a member 17 of the grading machine. The recesses 16 in the circumference of the drum 12 are dimensioned to pick up one fruit only at a time, and have substantially radial receiving walls and delivery walls which are tangential to a circle smaller than the root circle of the recesses. The drum may be in one piece or may be built up of two star wheels separated by annulµ both from one another and from side enclosing discs 15 of the same diameter as the star wheels. The side annulµ 14 are of similar diameter to that of the root circle of the recesses, and the central annulus 13 of smaller diameter, thus providing grooves into which central and side fingers 7, 8, of the conveyer trough 5, and similar fingers 18, 19 of the member 17, are introduced. The conveyer comprises two endless parallel round-sectioned belts 6a, 6b, of which 6a is short to deal with all the fruit precipitated on the conveyer and 6b is sufficiently long to take the fruit in single file to the drum 12. The conveyers may be driven by a band from a pulley 26 on the drum shaft 22, and may both be constituted by this band. The fruit is introduced to the conveyer by a periodically tilted sloping-hopper 2, and enters the conveyer below a fence 4 which permits only one row at a time to pass. The hopper 2 is oscillated about an axis a a by a lever 24 rocked by a cam &c. 23 on the shaft 22, and receives its fruit from a stationary platform 1.
