Title: Improvements relating to protection devices for electrical discharge vessels, particularly rectifiers
IPC: H02H7/127
Filed: 1934-06-29
Abstract: 420,282. Rectifying alternating current. SIEMENS - SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. June 29, 1934, No. 19288. Convention date, Sept. 7, 1933. [Class 38 (ii)] In rectifier installations employing gridcontrolled discharge devices in which the grids are subjected to a negative biassing voltage on which are superimposed positive voltage impulses for effecting ignition, the circuits from which the two voltages are derived are made interdependent and provision is made whereby in the event of fault conditions arising the negative bias is increased and the ignition impulses are simultaneously reduced or suppressed. In one arrangement, Fig. 1, the ignition impulses are derived from a transformer 2 fed through a choke or series transformer 4 from a supply 3. The negative bias is derived from a secondary winding on the transformer 4 associated with rectifiers 5. The core of the transformer 4 is normally saturated by a winding 6 in the circuit of the exciter anode 7. In the event of fault conditions arising, a switch 8 in the latter circuit is caused to open thus allowing the core of the transformer 4 to desaturate and thereby causing an increase in the biassing voltage and, by reason of an increase in the choking effect of the series transformer, a decrease in the amplitude of the ignition impulses. In an alternative arrangement, Fig. 3, in which the ignition impulses are supplied by a transformer 10 and the biassing voltage by a series transformer 12 through a rectifier 13, an automatic switch 14 actuated under fault conditions by a current transformer 15 in the primary circuit of the main supply transformer suppresses the ignition impulses and increases the negative bias by interconnecting the leads between the transformers 10 and 12.

Title: Improvements in sighting devices for air-craft
IPC: F41G3/22
Filed: 1920-07-08
Abstract: 147,486. Zeiss, C., [Firm of]. Aug. 13, 1917, [Convention date]. Sights.-Relates to bomb-dropping sights of the kind comprising a telescope having a sighting-mark which is rotatable relatively to the aircraft, either by itself or along with the telescope, and is therefore adjustable in the direction of flight, the sighting-line being primarily inclined at an angle a to the vertical in the vertical plane of flight of the aircraft, the angle a being determined by the equation tan a = vgt-R/H where vg is the overland-speed of the aircraft, t the time of fall of a bomb, R the lag of the bomb on the assumption that the air resistance acts only in the plane of flight, and. H the height of the aircraft. According to the invention, a wind correction is applied to the angle a by rotating the telescope objective, such correction having a component in the plane of flight and a component perpendicular to this plane. The invention is shown applied to a telescope sight mounted in gimbals to maintain the tube a vertical. The tube a is rotatably mounted in a ring b. The objective a<1> is carried by a ring d adapted to be rotated about a vertical axis Y Y to apply the wind correction. Below the objective are two reflecting prisms a<5>, a<6>, one of which a<6> is rotatable to incline the sight-line at the angle a. The tube a, ring d and fixed ring b are so connected by gearing that when the telescope tube a is rotated the ring d carrying the objective is rotated through the same angle in the opposite direction. In the zero position of the sight, the principal section of the prisms a<5>, a<6>, which is indicated by a course wire in the telescope, lies parallel to the fore-and-aft axis of the aircraft. In use the prism a' is rotated to set the sight-line at the angle a, and the tube a is rotated to bring the course wire parallel to the line of flight of the aircraft. The objective is thereby rotated and the wind correction applied.

Abstract: 1,224,890. Gear shaving machines. CHARLES CHURCHILL Ltd. 5 Dec., 1969 [16 Oct., 1968; 16 April, 1969], Nos. 49000/68 and 19502/69. Heading B3K. In a gear shaving machine having a worktable 15 pivotally mounted on a carrier 19 for horizontal reciprocation beneath a cutter 13 there is provided a crowning and taper shaving assembly comprising a slotted member 26 arranged for reciprocation with the carrier 19 in the longitudinal direction of the table, the slotted member 26 being connected to a toothed segment 20 which meshes with a stationary rack 21 to effect rotation of the member 26 simultaneously with its longitudinal movement, and a pin 28 mounted in a bearing 29 which is supported for independent vertical and horizontal adjustment on the table 15, the pin 28 engaging a radial slot 32 in the slotted member 26. If the pin 28 is so adjusted that it is coaxial with the pin 22 about which the member 26 rotates rotary movement of the latter is not transmitted to the table and no crowning takes place. Adjustment of the pin 28 horizontally (by means of screw 31) to a position in the slot 32 either to the left or right of the axis of the pin 22 provides for pivotal movement of the table 15 to result from the longitudinal movement and crowning or inverse crowning is effected. Adjustment of the pin 28 vertically relative to the table 15 (by means of screw 33) has no effect on crowning but moves the table 15 to an inclined position suitable for taper shaving. Suitable scales are provided adjacent the bearing mount 30 to indicate the crowning angle and degree of taper shaving. An alternative arrangement is envisaged in which the slotted member and pin are mounted on the table and knee respectively
