Title: Nesting device for paper containers
IPC: B65G57/16
Filed: 1935-12-07
Abstract: 448,393. Nesting paper containers. JAGENBERG - WERKE AKT. - GES., 107, Himmelgeisterstrasse, Dusseldorf, Germany. Dec. 7, 1935, No. 33972. Convention date, Dec. 8, 1934. [Class 18] A nesting device for paper containers which open out towards the top and which has a counter operated by the containers as they are fed into the pile is characterized in that a movably arranged support 2, which carries the pile S moves under the action of the weight of the pile after release from a stop 25 by the operation of the counter and is returned, after ejecting the pile, by a counter weight 5. Paper containers blown through a delivery tube are guided therein by a series of flat springs f, inclined to the direction of motion, until they rest against a stop. Each container in its passage actuates a spring-biassed feeler which makes and breaks an electric circuit to an electromagnet 10, the armature 11 of which operates a spring-biassed lever 13 to turn a ratchet 18 carrying a cam surface 22. After the passage of a number of containers equal to the number of teeth on the ratchet the cam 22 lifts the lever 24 and removes a stop 25 to allow the member 2 carrying the pile S to descend under its weight to deliver same, the member 2 being restored by the counter weight 5.

IPC: H02H7/125
Filed: 1959-10-08
Abstract: 930,647. Converting. SIEMENS-SCHUCKERTWERKE A.G. Oct. 8, 1959 [Oct. 24, 1958], No. 34145/59. Class 38 (2). In a rectifying installation including rectifying elements 4 having PN junctions (e.g. germanium or silicon rectifiers) projection against overload is effected by the provision of transductors 2. As shown the transductors are disposed on the input side of a supply transformer 3, and have control windings 2a<SP>1</SP>, 2b<SP>1</SP> energized from an auxiliary D.C. supply 7. Under normal conditions the transductors are continuously saturated by the auxiliary D.C. supply, but on overload desaturation arises so that the transductor presents a higher impedance and thereby limits the current to protect the rectifying elements. The transductors may be on the D.C. side. The transductor may have any of several known configurations.

Patent GB-921729-A (GB)
IPC: G04C3/06
Filed: 1960-10-12
Abstract: 921,729. Electric watches. FABRIQUES DES MONTRES ZENITH S.A. Oct. 12, 1960 [Dec. 28, 1959; May 9, 1960; May 19, 1960], No. 34983/60. Class 139. In an electronic watch the balance carries a magnet which, as it oscillates, induces impulses in a control coil, such impulses being returned to the magnet by a drive coil after having been amplified by at least one transistor. The axis of the magnet and the common axis of the coils are parallel to the balance axis, and the magnet is arranged to pass between the coils. In the rest position of the balance the magnet is displaced from the coils so that on application of a potential to the base of at least one transistor the emitter-collector current passes through the drive coil to give a starting impulse to the balance. In Fig. 1, the maintaining circuit includes a switch 10 which on closure introduces the resistor 9 so that the transistor 6 operates in class A and the resulting heavy emittercollector current passing through the drive coil 5 gives a starting impulse to the balance. The switch 10 can then be opened so that the transistor operates in class B and the transistor current is very small. If the maintaining circuit is of the form shown in Fig. 5 including two transistors 13, 14 and a capacitance 17, the transistor 14 starts operating in class A to effect starting of the balance; the charge on the capacitance 17 builds up to bias the base of the transistor 14 positively and switch it over to class B operation. Temperature compensation may be obtained by a bridge circuit comprising a battery 21, Fig. 8, fixed resistors 22-25 and resistors 26, 27 which vary inversely with temperature. The index wheel 31, Fig. 9, is stepped-on as the balance swings in one direction by a spring pawl 34 and a spring detent click 32, 33. In another example, Fig. 11, the capacitance is initially so charged because of the resistor 37 that the base is polarized and a heavy current flows in the collector circuit to start the balance. When the amplitude of oscillation of the balance becomes sufficient the transistor input resistance diminishes and the capacitance 38 is partly discharged so that the transistor base is no longer polarized. In a modification of this latter example a capacitance, a diode and a resistance are inserted between the collector and the emitter. Temperature compensation is obtained if the circuit of Fig. 11 is modified by the use of a battery between the emitter and base and a resistor which varies inversely with temperature. The relative internal and external diameters of the control and drive coils 52, 54 may be as shown in Fig. 17.

Title: Automatic variable speed gear
IPC: F16H61/02
Filed: 1930-11-25
Abstract: 364,274. Controlling change speed gearing; speed governors. JANIK, E., 5, Weimarerstrasse, Vienna. Nov. 25, 1930, No. 35507. [Class 80 (ii).] Change-speed gearing of the countershaft sliding-gear type is controlled by a centrifugal governor on the driven shaft, which governor disconnects the engine clutch upon a vehicle during each change, and is affected by the throttle to vary the automatic range in accordance with engine speed. Gears 3, 4, 9, Fig. 1, slide on the driven shaft 8, which is in line with clutch shaft 1 and parallel to a countershaft 48. The gears 3, 4, 9 are operated by separate striker forks 12b, 12a, 12, Fig. 9, with forked ends engaged alternatively by toothed discs 11b, 11a, 11 fast on a transverse shaft 43 geared at 51 to a parallel shaft 23 carrying a pinion engaging the governor sleeve 40, Fig. 1. The sleeve 40 is moved axially by toothed sectors f which also engage racks d, Fig. 5, on the governor weights 20. The weights 20 slide on a transverse rod 80 against springs 20b. As the governor functions, the gears 3, 4, 9 are moved separately to bring in direct drive and three reduced speeds. Changes are facilitated by synchronizing elastic friction discs R, S, one pair for each pair of gears, and also by a dashpot 27, Fig. 3, which delays the changing operation. The dashpot 27 is engaged by projections 29 on a sector 50 secured to shaft 23. The edge of disc 50 is formed with notches O, I, II, III, IV, so that during changing, the engine clutch pedal 54 is moved through a lever 52 to disengage that clutch. The shaft 23 is secured to a hand speed-control lever 24, Fig. 1, which during the automatic changing moves over a locking sector 76 to the left of a limiting stop a. A lock bolt 25 must be raised by hand to pass stop a and bring the gear to no-drive position. The accelerator pedal 400 is connected by a lever 30, spring 31, lever 34, and shaft 23 to the governor sleeve 40, so that the automatic range changes with the engine speed.
