Title: Percussion fuzes for projectiles
IPC: F42C15/26
Filed: 1936-03-13
Abstract: 466,055. Projectile fuzes. BIRKIGT, M. March 13, 1936, No. 7614. Convention date, Jan. 17. [Class 9 (i)] Relates to percussion fuzes of the kind in which the firing-pin is locked by balls which after the shot is fired bear on a surrounding conical wall whereby in moving outwards to release the firing-pin they displace a member longitudinally. According to the invention, the conical wall is normally out of the zone of action of the balls and is brought to operative position by the effect of acceleration when the shot is fired. In the form shown in Fig. 1, the balls 13 rest on a seat 14 and support a conical shoulder 18 on the firing-pin 7 so long as they are confined by the cylindrical rear part of a ring 16 held by friction in the forward position. When the shot is fired, the ring 16 sets back and a conical wall 17 thereon comes opposite the balls 13. These gather rotational speed and ride outwards and up the conical wall 17 to release the firing-pin. The conical shoulder 18 has a larger angle than the conical wall 17, so that the balls, in riding, out push the firing-pin forward before releasing the shoulder. The firing-pin is made of steel and is attached to a head of light metal 11 by a joint 20, which can yield to an accidental blow before the balls have moved out. The front of the fuze body 1 is closed by a small disc 10. In another form, Fig. 7, the balls 13 are normally confined by a tightly fitting cylindrical ring 22, which, when the shot is fired, sets back with a loose ring 23 on which the conical wall 24 is formed. The balls then wedge the ring 23 forward again in moving out to release the shoulder 12 of the firing-pin.

Title: Adjustable conducting roll apparatus
IPC: B22D11/128
Filed: 1972-02-18
Abstract: 1387844 Continuous casting USS ENGS & CONSULTANTS Inc 18 Feb 1972 [25 Feb 1971] 7699/72 Heading B3F [Also in Division B8] Relates to a drive roll apparatus for use in various portions of a strand path, e.g. for conducting a strand 10 down out of a mould 12 through pinch rolls 14, in a curved guide apron (or possibly driven rolls 16) as at B, in a straightener 17 as at A, or horizontally after straightening. In Fig. 2, it has a stationary frame 22, 23, 25 slidably supporting, e.g. in pairs of guides 27, a roll housing 30, 31, 32 in which are mounted bearing blocks 37, 38 (and a pair of rolls 34, 35 journalled in them), the block 37 being movable by power means such as two cylinders-andpistons 40 mounted between the blocks 37 and roll housing so that contraction of the power means moves the one roll 34 away from the other to allow a deviating strand end to pass between the rolls whilst subsequent extension of the means first moves the roll 34 into engagement with the casting end and then causes the roll housing 30-32 to rise in the side members 22, 23 of the frame and move the roll 35 towards roll 34. Should the strand be at too low a level, bottom piston-and-cylinders 46, 47, mounted on a base 25 of the stationary frame, are contracted to lower the rods 47 and the roll housing 30-32 resting on them. The rolls 34, 35 are driven by spindles 48, 49 flexibly attached to drive means. For servicing, the spindles are removable so that the housing 30-32 can be lifted off the rods 47 and out of the guides 27. The cylinders-and-pistons 40 are capable of bending a deviating strand end or of reacting to the deviation. In another embodiment, Figs. 4-6 (not shown), the roll housing consists of two side guides (53) movable in tracks (51). One roll (75) is fixed at one end of the guides, but the blocks (67) of the other roll (65) are movable in the guides and fixed to a support (59) between which and the other end of the guides (53) are mounted double-acting piston-and-cylinders (55, 54). Contraction of these latter first lifts the guides (53) and the roll (75) to receive the strand. Then extension of the rods (55) lowers the guides and roll (75) until it contacts the strand, when by further extension the roll (65) is raised as the support (59) is lifted off a rest 90 and the strand is clamped.

Title: Improvements relating to electrode holding devices for electrothermic melting furnaces
IPC: H05B7/105
Filed: 1951-04-03
Abstract: 693,068. Band clips. AKT.-GES FUR STICKSTOFFDUNGER. April 3, 1951 [April 3, 1950] No. 7728/51. Class 44 [Also in Group XI] An electrode is supported in an electrothermic meltingfurnace by contact plates 2 which are pressed against the electrode I and are supported by a closed flexible ring 4, the plates 2 being tightened on or loosened from the electrode by altering the snape ot the ring without altering its length. The circumference of the ring is widened or narrowed in a plane perpendicular to the axis of the electrode in order to loosen or tighten the plates 2 against the electrode without alteration of the length of the ring, the variation in circumference being effected by producing undulations in the ring by the action thereon of members movable in planes parallel with the axis of the electrodes. Connecting links such as springs or hydraulic or pneumatic devices may be arranged between the flexible ring and the contact plates so that the distance between the flexible ring and each contact plate undergoes equal changes on tightening the ring. The flexible ring 4 is a stranded wire rope, a link chain, a marine chain or a Gall chain and when used below the furnace cover is surrounded by a tubular flexible jacket for circulation of cooling liquid or inert gas. The rope 4 is supported in Fig. 1 by hooks 11 on a curved arm 3 bearing on wedges 10 on the contact plates 2. A hydraulic piston 15 raises a rigid ring 6 with draw bars 5 having at their lower ends hooks 12 engaging the curved bar 3 which pivots on the wedge 10 to clamp the electrode. The bars 3 may be replaced by rollers. In Fig. 4, the rope 4 is engaged by draw bars 5 attached thereto between the contact plates 2, which are tightened equally on the electrode by raising the draw bars. The electrodes are of circular or polygonal cross section, and may be composite as in Fig. 10. When the chain protrudes from the cooling jacket it may be replaced by a metal cylinder or wire rope. When the curved arms 3 forming roll off levers are used, they may be secured to the contact plates 2 by indents or furcations.

Abstract: 794,973. Electric resistors; capacitors; semiconductors. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 28, 1954 [Sept. 28, 1953], No. 7994/56. Divided out of 794,971. Class 37. A printed circuit component is made by printing a negative mask of the desired pattern on an insulating backing, applying by vacuum deposition a conducting, resistive or semi-conducting coating over the whole, forming a subsequent layer by further printing and coating and removing the masking material and coatings superimposed thereon. A negative mask of the desired resistive or semi-conducting areas may first be printed on the base and a coating of resistive or semi-conducting material applied after which the mask and overlying coating are removed. An alternative method comprises printing on the base a negative mask of the desired resistive or semi-conducting pattern, applying a coating of resistive or semi-conducting material, printing a second negative mask of the desired conducting pattern thereover, coating this with conductive material, which adheres to the exposed areas of the resistive or semi-conducting coating, then removing the masking layers and any superimposed material. Two or more successive layers of resistance material may be applied to obtain the desired resistivity. A nickel-chromium alloy may be used for the resistance material and selenium or germanium for semi-conductors. The insulating base may comprise polyester-bonded glass laminates, glass, paper-based. " Bakelite " board or " Araldite " (" Bakelite " and " Araldite " are Registered Trade Marks). The component may be rolled or folded and encased in plastic, wire leads soldered to the films of nickelchromium and being brought out for connection. Condensers may be made of metallizing an area on both surfaces of an insulator or metallizing similar areas on one side of a sheet insulator which is then folded, additional layers being placed within the folds if necessary.

Title: Improvements in or relating to electric timing circuits
IPC: H03K17/288
Filed: 1964-02-26
Abstract: 1,045,802. Road traffic signals. S.G.E. SIGNALS Ltd., H. J. N. RIDDLE and E. C. D. HOWARD. Feb. 3, 1965 [Feb. 26, 1964], No. 8003/64. Heading G4Q. In a vehicle-operated traffic signal system the green period on one road is given a standard extension on demand for a change of right of way, and this is followed by a variable extension dependent on traffic density in the road. During the green period the contact RS1 is in the opposite position to that shown, and a capacitor 8 is alternately charged from a source 11 and discharged into a storage capacitor 21 by a vehicle-operated relay contact RT1, so that the charge on capacitor 21 is proportional to traffic density. When there is a demand for change of right of way, a standard extension is timed by means not shown and at the end of this period relay RS is released. The valve 6 is held non-conducting by an initial charge on capacitor 33 which starts discharging through resistors 35. The charge on capacitor 33 is replenished from capacitor 28 via zener diode 32 each time contact RT2 is changed over by vehicle actuation, the capacitor 28 being charged from capacitor 21 which also discharges through resistor bank 22. When capacitor 33 discharges sufficiently the valve 6 contacts and changes over relay RG which operates the traffic lights. When relay RS is released its contact RS2 causes relay RT to be energized so that contacts RT2 are operated to provide the initial charge on capacitor 33 even if no vehicle is present. Resistance banks 22 and 35 can be adjusted individually for each route; resistance 22 controls the extension granted for a given traffic density, and resistance 35 adjusts the threshold of diode 32 to control the traffic density required to give a further extension.

In a compatible colour television system employing an amplitude-modulated sound carrier of frequency fs the relationship necessary to obtain compatibility (i.e. nfL = fv -fs) between the line scanning frequency fL and the difference between the vision and sound carrier frequencies fv - fs is obtained by applying the composite vision signal produced by the camera chain 1 and the colour information to transmitter 2 and to synchronizing pulse separator 3. The output fL of circuit 3 is applied to frequency multiplier 4, the multiplier output nfL being applied to mixer 5 whose other input is a sound carrier fs derived from modulator 7 and transmitter 6. The output of mixer 5fv is applied as the carrier input to the vision signal transmitter 2. The multiplication factor n is chosen to satisfy the equation nfL = fv - fs.

Title: Improvements in or connected with parallax measuring instruments
IPC: G01C3/14
Filed: 1943-05-24
Abstract: 580,531. Range-finders. BARR & STROUD, Ltd., and FRENCH, SIR J. W. May 24, 1943, No. 8204. [Class 97 (i)] Relates to the arrangement of the optical parts in a range- or height-finder whereby parallax errors due to a temperature gradient transverse to the base (set up for example by the sun heating one portion more than another) are wholly or substantially either annulled or compensated. The invention is applicable to instruments either of the stereoscopic or of the coincidence type and several arrangements are described. In Fig. 5, for example, instead of the arrangement in the right-hand system of a stereoscopic instrument being the mirror image of that in the left-hand system, a roof pentagonal F<1> replaces the roof reflector E and a plain reflector B<1> replaces the pentagonal A. The effect of the unequally heated air in the systems may be represented by hot air prisms 10, 11, 12, 13, the effects of which, combined with the additional reflection in F<1> is to deviate each ray through the eyepieces in parallel directions and by equal or substantially equal amounts x + y, where x is the effect of prisms 10 and 12 and y that of prisms 11 and 13. As shown in the imcompensated form of Fig. 3, with a symmetrical arrangement in the two systems, the rays would be deviated in diverging directions and no compensation would be provided. In Fig. 12, projector lenses 25, 26 are arranged in the systems. The deviations 2x to the focal planes 27, 28 are annulled by the deviations 2y between the focal planes and the eyepiece prisms E<4>, F<4>. In Fig. 13, the left-hand focal plane 27 is further from the end prism A than the right-hand focal plane 28 is from the end prism B. The deviation effect of prisms 29 and 30 is greater than that of the prisms 31, 32 and there is a residual deviation. at one eyepiece which is parallel to that at the other eyepiece. In Fig. 14, the rays are reversed by prisms M and the image formed at the focal plane H is returned by prisms N to the eyepiece prism E<5>. If the column of hot air AM is equal to the column MH, annulment up to the focal plane H is effected. No compensation beyond the focal plane H containing the reference mark is necessary as other refraction due to hot air will effect the image and reference marks equally. In the coincidence type shown in Fig. 18, the ray from the left window 50 is passed into the eyepiece separating prism 44 by the prism S and that from the right window by the pentagonal T, and parallax angles are measured by prism 55 which can be translated along the right beam and a scale 60 read through a window 59. Specifications 15140/14 and 2114/15, [both in Class 97 (i)], are referred to.

Abstract: 932,708. Cores for electric motors. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. March 9, 1960, No. 8318/60. Class 35. A small three-phase induction motor has only three bobbin-wound salient poles (i.e. one per phase) for each stator pole-pair, most of the stator flux passing through leakage webs 11 between the poles, and a smaller proportion through the rotor. The invention may be applied to split-phase (capacitor) motors which normally have four salient poles for a two-pole machine, i.e. two main poles and two auxiliary poles. The machine may have three poles, the bore being lined by a laminated sleeve having thin areas between the poles (Fig. 4, not shown). But in the form shown, six salient poles 5-10 give four electrical poles. The three phase windings are delta-connected with the phase splitting condenser across one side. The Dahlander connection, Fig. 2b, may be used to give two-pole operation. The leakage webs may be integral with the poles and of stepped thickness, the stator being enclosed by a peripheral ring. In a further modification, the pole shoes are bridged by inserts of magnetic material (Fig. 5, not shown).
