Title: A device for suspending bombs from aircraft
IPC: F42C19/04
Filed: 1924-11-28
Abstract: 233,262. Remondy, L. E. Nov. 28, 1924. Dropping bombs.-A cap adapted to protect the fuze of a bomb to be dropped from aircraft is provided with a suspension clasp and with means for holding the bomb, the arrangement being such that the bomb can be dropped with or without the cap, and the fuze is armed or not according to the manner in which the bomb is dropped. As shown in Figs. 1 and 2, the fuze C of the kind described in Specification 172,326, is retained by a pin c in the fuze body B, the part b<2> of which fits in a cap D provided with a ring E for suspension from an aircraft. The cap D is slotted longitudinally at d, forming spring laths d<1>, which tend to open out, but are normally held in by an embracing collar F, itself locked by a pin H and a cotter G. When these parts are thus locked, the bomb is held by a bevelled shoulder d<2> in the cap D in engagement with a shoulder b on the fuze body. If the cotter G is pulled out, for example by a cable g, the collar F and the laths d<2> of the cap 'D are wedged out of the bomb, which drops free from the cap and therefore armed for explosion or impact. If, however, the bomb is dropped with the cap by releasing the ring E, then, although the cotter G may be pulled out, there is no force tending to withdraw the cap from the bomb, and the fuze remains protected and no explosion occurs. In a modification, the cap is detached from the bomb by spring action when the cable g is pulled to unlock the collar F, the bomb is then dropped in the armed condition when the ring E is released unless the cable g is previously disconnected from the aircraft. In other modifications, (1) the cap is adapted to be removed from the bomb by a lateral tilting action due to springs or to an uneven distribution of weight or of resistance to the air, and (2) the bomb is held in the cap by means of balls surounded by a sleeve, which may be made like an outer cap surrounding the main one.

Filed: 1974-06-27
Abstract: 1462720 Bi-stable circuits BASSANI TICINO SpA 27 June 1974 [24 July 1973] 28615/74 Heading H3T Input pulses are steered alternately to the set and reset inputs of a bi-stable circuit G1, G2 by a steering circuit comprising an RC networks R1, C1, R2, C1 coupled between an input terminal S and the bi-stable circuit inputs and means R3, C3 for switching the time constant of the first RC network between two values, one higher and one lower than that of the second RC network in dependance on the state of the bi-stable circuit, the arrangement being such that input pulses at S are steered to that bistable circuit input to which the higher time constant RC network is connected. Assume initially the time constant of elements R1, C1 is greater than that of R2, C2, the output of gate G2 is "0", and the output of gate G1 is "1" to charge capacitor C3 such that diode D is cut off. Then an input pulse will be steered via C1, R1 to switch the state of the bi-stable to give a "0" output from G1 and a "1" output from G2. Capacitor C3 now discharges until diode D becomes conductive to connect C3, R3 to C1, R1 thus reducing its time constant to a value lower than that of C2, R2. The next input pulse will then be steered via C2, R2 to reset the bi-stable to give a "1" output from G1 and a "0" output from G2. Capacitor C3 now charges again to turn off diode D,thus disconnecting R3,C3 from R1, C1 so that its time constant is again greater than that of R2, C2.

Title: Improvements in and relating to dynamo-electric machines
IPC: H02K3/28
Filed: 1952-11-13
Abstract: 736,520. Winding layouts for dynamo-electric machines. GENERAL ELECTRIC CO. Nov. 13, 1952 [Nov. 20, 1951], No. 28648/52. Class 35. The invention relates to a layout of double windings on A.C. generators. The layout described in Specification 366,184 comprises a generator winding having two separate but identical parts formed by dividing each phase belt into equal groups of slots and assigning one group to each winding. According to the present invention the phase belts are each split into more sections than there are windings, i.e. for two windings, into three or more sections, at least two of which have different numbers of conductors. The fom shown is a two layer lap winding having two separate three-phase windings a, b, c and A, B, C, phases a and A only being shown in heavy and light lines respectively, and conductors in the bottoms of slots being shown dotted. The two layers may be con. sidered separately for convenience. Each phase belt comprises coil sides of the two windings belonging to similar phases and corresponding to one pole. Thus, the first phase belt of the top layer is AAaaaAA, i.e. it comprises three sections of 2A, 3a and 2A respectively. The voltage of the whole windings are kept the same by means of appropriate reversals between the conductors of the two windings at every other phase belt, i.e. the layout of the next phase belt is 2a, 2A, 2a. Each phase belt is thus of the same 2, 3, 2 pattern and the arrangement of the bottom layer is the same as the top with the appropriate shift to give the desired pitch to the coils. In the case of machines having more than two poles, the reversals of the conductors in each phase may take place at each third or more phase group. Modifications are described having equal numbers of conductors of each winding in each phase belt, in which the layouts are 2A, 4a, 2A, &c., and 1A, 3a, 3A, la, &c. For fractional slot machines layouts 2a, 3A, 2a; 3a, 3A; 2A, 3a, 2A, &c. and 2A, 4a, 2A; 2A, 3a, 2A; 2a, 4A, 2a, &c. may be used. Specification 311,344, [Class 38 (iv)], is referred to.

Filed: 1937-10-21
Abstract: 487,375. Gauges. STEINMETZ AKT.- GES., A. L. Oct. 21, 1937, No. 28795. Convention date, Oct. 22, 1936. [Class 106 (ii)] Comprise a particular construction of the micrometer screw three-point contact V-gauge type for cylindrical pieces. A body a is formed with a V-shaped recess having surfaces b, b. Bisecting the angle c is the axis of a sleeve d slidable to a limited extent without rotation on ball bearings e in a bore of the body a. Slidable in the sleeve d is an anvil g moved by a micrometer screw. An arm k on the sleeve engages the feeler pin h of a dial gauge m carried by the body. A pin f projecting into a groove in the sleeve prevents rotation of the sleeve and limits its axial movement. If the distance moved through by the anvil from its position to gauge the smallest diameter of the range to the position for the largest diameter is divided into 100,1,000, or 10,000 parts and the screw is graduated accordingly the dial gauge m will read zero in positions of maximum or minimum range. In use the screw is set to the dimension and differences noted on gauge m.

Abstract: 945,070. Protractors. C. PIERCE, and W. W. ANDREWS. Sept. 17, 1962 [Aug.10, 1961], No. 28973/61. Heading G1X. A protractor comprises an outer ring 2 adapted to be rotatably received in a mount 1, an inner ring 3 supporting a screen and rotatably received in the outer ring, the screen having a plurality of radial lines of known angular spacing, means for locking the inner ring against rotation with respect to the outer ring, and a gauge 11 for indicating angular displacement of the outer ring 2 relative to the mount 1. The ring 3 is held in place in the ring 2 by a clip 5 and knobs 6 are provided for manual rotation of the ring 3. The locking means comprises a block 7, secured to the ring 2, provided with a clamping screw 8 for locking the ring 3. The block 7 has a shoulder 9 engaging the movable head 10 of the gauge 11, a tension spring 12 being provided to ensure engagement. The shape of the shoulder 9 is such as to provide a linear relationship between angular movement of the ring 2 and linear movement of the head 10. In use an image of a workpiece is projected on the screen 4, which is translucent, and the ring 3 is rotateduntil the 0 degrees reference line on the screen coincides with one side of the angle to be measured. The ring 3 is then clamped to ring 2 and the other side of the angle to be measured will then fall between two other radial lines on the screen. These lines are conveniently at 5‹ intervals and the angles are measured from the reference line in an anticlockwise direction. The gauge 11 is then adjusted to make the other side of the angle coincident with the lower value line of the two between which the side originally fell. The gauge is calibrated to read 0 to 5 degrees and thus the angle to be measured is given by adding the reading of the gauge 11 to the marked value of the appropriate radial line.
