Title: Improvements in or relating to voltage regulators
IPC: H02H7/06
Filed: 1963-04-05
Abstract: 1,035,071. Automatic voltage control. ROBERT BOSCH G.m.b.H. April 5, 1963 [April 7, 1962],No.13584/63. Heading G3R. In a voltage regulator of the kind in which the field winding of a generator is connected in series with a main transistor controlled by a second transistor in dependence upon output voltage variations, the transistors are protected against possible overload, should a short-circuit occur in the field winding, by a circuit including a semi-conductor controlled rectifier. As shown, a main transistor 26 connected in series with the field winding 16 of a generator 15 is controlled by a second transistor 27 in dependence upon output voltage variations whereby the field current is varied to counteract these variations in known manner. Resistors 28, 29 and a diode 30 connected in series between the positive lead 18 and the base of transistor 26 ensure excitation when the generator starts from standstill. The overload protection circuit includes an input resistor 40 and a potentiometer 41 connected in parallel between the transistor 26 and the negative lead 20, and a semi-conductor controlled rectifier 42 having its anode connected to the collector of transistor 27 and to the junction of resistors 28 and 29, its cathode connected to negative lead 20, and its control electrode connected to the slider 44 of potentiometer 41. The arrangement is such that if excessive current flows through transistor 26 because of a fault in the field winding 16, the increased voltage at slider 44 renders the controlled rectifier 42 conductive so that transistor 27 is short-circuited by a low impedance path; also, the current flowing through resistor 28 and rectifier 42 is of such magnitude that the main transistor 26 returns to its blocked condition. Transistor 26 is thus protected and the circuit returns automatically to normal operation when the fault is removed. In a modification (Fig. 3, not shown), for use with a generator having an operating voltage of about 100V, a diode is connected in series with the controlled rectifier and the junction between the diode and the rectifier is connected to a tapping point of a voltage divider shunting the output terminals.

Filed: 1937-05-14
Abstract: 484,634. Controlling shock-absorbers. FICHTEL & SACHS AKT.-GES. May 14, 1937, No. 13729. Convention date, May 16, 1936. [Class 108 (iii)] In a piston and cylinder type of shock-absorber, the throttle valve 15 controlling the flow of liquid from cylinder 10 is loaded by a spring 22 the pressure on which is adjusted by an axially movable flanged sleeve 15a abutting a nut 23 screwed onto a lug on a casing 12. As shown in Fig. 1 the rod 19 and valved piston 18 moves up or down in the cylinder 10, on relative movement between the sprung and unsprung parts of the vehicle, and forces liquid at each direction of movement through the throttle valve 15. The displaced liquid flows in a closed circuit downwardly through the annular space between the cylinders 10, 12 and enters the space below the piston through a valve 28. The tension of the spring 22 on the throttle valve 15 is adjusted by turning the nut 23 either directly or through the medium of a depending skirt attached to the nut. In Fig. 3 the cylinder 12 is screwed at 25 to the lower cylinder head and by screwing the cylinder on or off the head the tension of the spring 22 on the throttle valve 15 is adjusted. Specification 458,895 is referred to.

Title: Dolls or other movable devices and vibration apparatus for moving such dolls or devices
IPC: A63H11/00
Filed: 1953-05-18
Abstract: 742,818. Kinematograph cartoons. GARBEN, A, R. May 18, 1953, No. 13826/53. Class 97 (1). [Also in Groups XV and XVIII] A doll, toy figure or like movable device adapted to become animated when stood upon a vibrative surface includes a supporting member or members, the geometric centre of the area of the vibrative surface defined by the supporting member or members being offset in relation to the projection of the centre of gravity of the device on the said surface and along a line perpendicular to the plane of said defined area. The apparatus may be used in production of trick kinematograph films. In Fig. 1, supporting members U<SP>1</SP>, U<SP>2</SP>, U<SP>3</SP> secured to a toy figure A define a triangular area on a vibrating diaphragm B and the position of the centre of gravity t of the figure is such that the point t<SP>1</SP> on the diaphragm corresponding to the projection on the triangular area from the centre of gravity t does not coincide with the geometric centre m of the triangular area. Fig. 2 shows cylindrical devices 8, 9 which when placed at the centre of the vibrating diaphragm move away therefrom and then move around the diaphragm circumferentially at the radii indicated, these radii corresponding to the angles which the support surfaces of the devices form with the longitudinal axes of the devices. Weights 10 may be added, Fig. 3, to produce movement of the cylinders around their own axes: Change of position of the centre of gravity may alternatively be effected by providing a slot in the cylinder and the cutting of a corner adjacent the slot, Fig. 4 (not shown). The doll shown in Fig. 5 has a stiff skirt 29 on which it rests and the skirt may be adjusted to vary the distance apart of the supporting points formed by three or four of the skirt pleats. The position of the umbrella 30 is also adjustable. In Fig. 6 (not shown), a figure is mounted on a brush-like member. Fig. 7 shows a cylindrical member 22 in which is freely retained a ball 27 having an asymmetrically disposed centre of gravity, the ball striking the cylinder intermittently and producing a spontaneous movement of a doll 23, which may have movable limbs and head. The diaphragm may have a number of guide plates or projections or concentric rings and may be of varying thickness or damped in places to produce varying effects on the movable objects. The damping may be controlled by pads actuated from a keyboard. More than one diaphragm and vibration generator may be provided and figures may move from one diaphragm to another. The vibration generator may be energized from a music reproducing apparatus. The diaphragm may be on supporting columns and when the apparatus is used for advertising, these parts may be of a transparent material, e.g. a plastic, and a vibration generator and associated components may be mounted out of normal view. Movable devices representing cigarette boxes are specified. Moving shadow effects may be produced by combining the apparatus with a light source and a curved screen.

Abstract: 1,067,945. Measuring reactive characteristics. FUNKWERK DRESDEN, V.E.B. April 1, 1965, No.13877/65. Heading G1U. A circuit arrangement for the measurement of complex two terminal and four terminal parameters includes four lines 2.1-2.4 of equal electrical length which extend between a generator 1 and four rotatably arranged coupling loops 3.1-3.4 which are disposed in the vicinity of slotted regions of outer conductors of four coaxial lines 5.1-5.4 arranged in a common plane and of short length compared with the wavelength at the measuring frequency. The inner conductors of three of the coaxial lines 5.1-5.3 meet at a junction 4 while the inner conductor of the fourth line is terminated in the vicinity of the junction in such a manner as to be short circuited at high frequencies. A coaxial null indicator line 7 is provided extending from the point 4 perpendicularly to the plane of the lines 5.1-5.4 to an indicator 8 and from this line 7 in the vicinity of the junction 4 a further coaxial line 6 short in comparison with the measuring frequency extends, terminated at substantially the same location as the end of the line 5.4. To use the apparatus to measure the parameters of a four terminal network, the loop 3À1 is adjusted so that no voltage is induced in the line 5À1, the lines 5.2, 5.3 are terminated with a standard admittance 10 and susceptance 11 respectively, and the four terminal network is connected between the lines 5.4 and 6, one input and one output terminal being earthed. The loops 3.2, 3.3, 3.4 are then adjusted until a null is obtained on the meter 8. The settings of the loops enable the parameters to be evaluated. The parameters of a two terminal network 12 may be determined similarly by connecting it  to the line 5À1 and setting the loop 3.4 so that no voltage is induced in the line 5.4. An alternative arrangement using double coupling loops is described Fig. (not shown).
